{This study examined the relationship between hamstrings-to-quadriceps strength ratio (H:Q) and relative strength of the knee extensors in elite soccer players. Peak torque was measured during isokinetic knee extension/flexion at angular velocities of 60°·s-1, 180°·s-1 and 300°·s-1. 18 professional players were divided into 2 groups, depending on their H:Q at 60°·s-1. Players in the lower H:Q group (n=7) had significantly smaller H:Q ratios compared with the higher H:Q group (n=11) at all angular velocities (60°·s-1: 49.2%; 95% CI: 61.3-57.8% vs. 59.5%; 95% CI: 52.2-46.2%

Le projet d’universitarisation des études françaises en Grèce est conçu dès la fin du XIXe siècle. Il s’inscrit dans le cadre des stratégies étatiques mises en œuvre par la Grèce et la France en vue de promouvoir leurs intérêts culturels, économiques et politiques respectifs. À Thessalonique, il se concrétise par des initiatives visant, entre les deux guerres, à faire fonctionner une chaire de langue et littérature françaises au sein de la nouvelle université créée en 1925. Or, la période comprise entre la publication de la loi constitutive et la Seconde Guerre mondiale est surtout jalonnée de projets délaissés, de régressions et d’accélérations qui laissent percevoir la multiplicité des enjeux impliqués. Cependant, au cours de la décennie qui suit le conflit et sous l’effet du processus de recomposition des zones d’influence des grandes puissances, émerge en Grèce, en matière de disciplinarisation académique des littératures étrangères, un nouveau paysage universitaire composé de structures issues de conventions culturelles bilatérales : dans ce contexte, est née, en 1954, après de longues négociations menées entre les gouvernements hellénique et français, la section salonicienne d’études françaises, formule de préparation professionnelle qui, intégrée dans l’Institut de langues et littératures étrangères, devait durer jusqu’à la fin des années 1970. The project of the universitarization of French Studies in Greece has been conceived and designed since the late nineteenth century. It is part of state strategies implemented by Greece and France to promote their respective cultural, economic and political interests. In Thessaloniki, it materializes through initiatives launched during the interbellum and aiming at the creation of a Chair of French Language and Literature in the new university. However, the period between the publication in 1925 of the law establishing this University and the Second World War is mostly dotted with abandoned projects, regressions and accelerations that allow us to perceive the multiplicity and complexity of issues involved. Nevertheless, during the decade following the conflict and under the effect of the processes of recomposing the influence zones of the Great Powers, a new landscape for both Greek Schools of Humanities emerges, characterized mainly by the academic disciplinarization of Foreign Languages. It is formulated by structures stemming from bilateral cultural conventions. In this context and after lengthy negotiations between the French and the Greek government, a French Studies Department is integrated in the Institute of Foreign Languages and Literatures of Thessaloniki in 1954. This new academic formula for initial teacher professional preparation was to last until the late 1970s.

Involvement of the central nervous system (CNS) is a rare complication of multiple myeloma (MM). Herein, we have described the incidence, characteristics, prognostic factors for post CNS-MM survival, and outcome of CNS-MM and explored the efficacy of novel agents (NA) (thalidomide, bortezomib, lenalidomide) in this setting. Between 2000 and 2013, 31 (0.9 %) out of 3408 newly diagnosed symptomatic MM patients, consecutively diagnosed and treated during the same period in 12 Greek centers, developed CNS-MM (M/F 15/16, median age 59 years, range 20–96 years; newly diagnosed/relapsed-refractory 2/29; median time to CNS-MM diagnosis 29 months). Clinical and laboratory characteristics were retrospectively recorded. Twenty-six percent of patients had circulating plasma cells (PCs) or plasma cell leukemia (PCL) at CNS-MM and 39 % had skull-derived plasmacytomas, suggesting hematological and contiguous spread. Treatment for CNS-MM was offered in 29/31 patients and 11/29 responded (NA 18/29, additional radiotherapy 9/28, intrathecal chemotherapy 13/29). The median post CNS-MM survival was 3 months (95 % CI 1.9–4.1) and did not differ between patients treated with NA and/or radiotherapy vs. others. In the multivariate analysis, prior treatment of MM with NA, extramedullary disease (EMD) during MM course (i.e., plasmacytomas, circulating PCs, or documented PCL) and abnormally high LDH at MM diagnosis were independent prognostic factors, whereas treatment of CNS-MM with NA did not predict for post CNS-MM survival. Despite the relatively limited number of patients due to the rarity of CNS-MM, our results suggest that NA do not seem to improve post CNS-MM survival. Patients with EMD display shortened post CNS-MM survival and should be followed thoroughly. © 2015, Springer-Verlag Berlin Heidelberg.

Remains of past sea levels, such as tidal notches, benches, beachrocks, etc. may provide valuable information for the investigation of relative sea level changes of eustatic and/or tectonic origin. Tidal notches are usually formed in limestone cliffs in the mid-littoral zone, are well known as precise sea-level indicators and they can attest to the modality of sea level change (rapid or slow) allowing to identify palaeoseismic events. In this framework, this work focuses on the eastern coasts of the Attica Peninsula (eastern Greece) in order to trace the palaeoshorelines of the Upper Holocene through the use of tidal notches and discuss their implication for the interpretation of the recent tectonic history in the area. A submarine geomorphological investigation took place in the coasts of eastern Attica, aiming to identify palaeoshorelines. Former sea-level positions were deduced from emerged and submerged tidal notches. An attempt was made to date past sea level positions, based on 14C datings from sedimentological data of drillings in nearby locations for the submerged tidal notches while one uplifted shoreline was dated with 14C based on a shell collected at a nearby location. Eight fossil shorelines were deduced in the study area; two emerged ones at about +24±6 and +40±6 cm, and six submerged ones at about -22±6 (modern), -40±6, -60±6, -80±6, -130±6 and -460±6 cm. It is worth mentioning that a rather different tectonic behavior may be distinguished between the south (AT1-AT5) and the north (AT10-AT28) part of the study area.

À la charnière des XIXe et XXe siècles, dans un contexte de concurrence franco-allemande accrue dans l’espace balkanique, l’absence en Grèce d’une formation officielle pour francisants, vite associée au faible niveau de l’enseignement donné dans les établissements publics, fut considérée par les milieux de la diplomatie culturelle de l’Hexagone comme un obstacle notable à la promotion de la langue française. Pendant une période de trente ans, jalonnée de projets délaissés et de tentatives mort-nées, de régressions et d’accélérations, l’École française d’Athènes, établissement culturel dont l’une des missions originelles était l’enseignement, mena de difficiles négociations, officieuses et officielles, avec le gouvernement grec en vue d’être chargée de la mission de former les francisants grecs. Le projet français trouve sa réalisation en 1930 dans la loi qui créa la première structure franco-hellénique de préparation au professorat de français et confia le monopole de l’organisation des enseignements de spécialité à l’Institut supérieur d’études françaises, annexe de l’École française d’Athènes.On the verge of the twentieth century, in the midst of an ever increasing antagonism among the great powers in the Balkans, the absence in Greece of a formal instruction for teachers of French was considered by the French cultural diplomacy as a serious obstacle towards realizing the latter’s linguistic political agenda in the area. For thirty years, the French Archaeological School – a cultural institution founded in Greece in 1846 aiming, among other things, to promote the French language through Education – conducted negotiations with the Greek government in order to undertake the responsibility of professionally training Greek teachers of the French Language. This French pursuit was finally realized by the 1930 law, which created the first relevant Greek-French formation structure and assigned the monopoly of organizing specialization courses to the educational branch of the French Archaeological School, the French Institute.

Le but de l’article est de décrire une expérience éducative réalisée en contexte universitaire, afin de discuter de la contribution du tutorat par les pairs au développement de la compétence pédagogique des futurs et novices enseignants de FLE. L’étude de cas en question a duré tout au long d’un semestre académique et a impliqué des étudiants du 1er et du 2e cycle.

The dorsiventral, hypostomatic leaf of Euphorbia characias is investigated to disclose its structural features and the chemical nature of the secondary metabolites produced. Light and scanning electron microscopy along with histochemical tests were employed to investigate the leaf of this well known perennial dwarf Mediterranean shrub. The compact leaf is characterized by numerous, rather uniform, curly, unicellular hairs on both surfaces, vaulty protrusions of the outer periclinal walls of the epidermal cells, prominent on the lower epidermis in particular, and a network of latex producing ducts (laticifers) extending in two layers within the mesophyll. Histochemical reactions proved positive only for alkaloids within the laticifers and phenolic compounds, especially for the condensed tannins accumulated within the vacuole of the epidermal cells. GC-MS and GC-FID analyses of the latex revealed the presence of several secondary metabolites, mainly belonging to the class of triterpenes. Lanosterol, butyrospermol, cycloartenol and lupeol were the major constituents in the extract examined. © 2014 Elsevier GmbH.

Biomechanical findings show that running is asymmetric in many kinetic properties. Running stiffness is a vital kinetic property of yet unknown pattern of lateralization. The aim of this study was to examine the degree and variability of lower limb dominance specific asymmetry of running in terms of leg stiffness, vertical stiffness, contact time, flight time, maximal ground reaction forceduring contact, vertical displacement of the center of mass, and change in leg length. Leg and vertical stiffness was estimated by the sine-wave method in 22 young males during treadmill runningat 4.44m/s. Lower limb dominance was determined by the triple jump test. Asymmetry was expressed as dominant – non-dominant, and indexed by the absolute asymmetry index. Significant asymmetry was found only in flight time (3.98%) and in maximal ground reaction force (1.75%). The absolute asymmetry index ranged from 1.8% to 6.4%, showed high variation between subjects (0–31.6%), and differentiated among the 7 analyzed variables. Leg and vertical stiffness in treadmill running of moderate pace (4.44 m/s) should be considered symmetric.

This is the first of a two-volume final report on the excavation of the Minoan cemetery and associated finds at Livari Skiadi, near Goudouras, at the southeastern end of Crete. The cemetery was unearthed during a rescue excavation performed by the 24th Ephorate of Prehistoric and Classical Antiquities of the Hellenic Ministry of Culture, under the direction of Chrysa Sofianou, who was at that time responsible for the antiquities of the Siteia prefecture, and with the participation of Yiannis Papadatos, together with a small group of archaeology students from the Department of History and Archaeology of the National and Kapodistrian University of Athens. The excavation lasted three consecutive summers, from 2008 until 2010, and it revealed a tholos tomb and burial rock shelter used in the Prepalatial period, a house tomb dated to the Neopalatial period, and deposits of funerary material in open areas surrounding these tombs.

Bortezomib and lenalidomide are increasingly used in patients with AL amyloidosis, but long term data on their use as primary therapy in AL amyloidosis are lacking while early mortality remains significant. Thus, we analyzed the long term outcomes of 85 consecutive unselected patients, which received primary therapy with bortezomib or lenalidomide and we prospectively evaluated a risk adapted strategy based on bortezomib/dexamethasone to reduce early mortality. Twenty-six patients received full-dose bortezomib/dexamethasone, 36 patients lenalidomide with oral cyclophosphamide and low-dose dexamethasone and 23 patients received bortezomib/dexamethasone at a dose and schedule adjusted to the risk of early death. On intent to treat, 67% of patients achieved a hematologic response (24% hemCRs) and 34% an organ response; both were more frequent with bortezomib. An early death occurred in 20%: in 36% of those treated with full-dose bortezomib/dexamethasone, in 22% of lenalidomide-treated patients but only in 4.5% of patients treated with risk-adapted bortezomib/dexamethasone. Activity of full vs. adjusted dose bortezomib/dexamethasone was similar; twice weekly vs. weekly administration of bortezomib also had similar activity. After a median follow up of 57 months, median survival is 47 months and is similar for patients treated with bortezomib vs. lenalidomide-based regimens. However, risk adjusted-bortezomib/dexamethasone was associated with improved 1-year survival vs. full-dose bortezomib/dexamethasone or lenalidomide-based therapy (81% vs. 56% vs. 53%, respectively). In conclusion, risk-adapted bortezomib/dexamethasone may reduce early mortality and preserve activity while long term follow up indicates that remissions obtained with lenalidomide or bortezomib may be durable, even without consolidation with alkylators. © 2015 Wiley Periodicals, Inc.

Consecutive patients that had primary metal-on-metal (MoM) or metal-on-polyethylene (MoP) hip arthroplasty were prospectively enrolled to this study. All operated hips were evaluated with MRI by one radiologist who was blinded to the radiographic findings and clinical symptoms. Three groups of patients were formed: (1) thirteen MoM THRs in 13 patients with groin pain (Group 1), (2) ten MoM THRs in 10 patients with no pain (Group 2), (3) five MoP THRs in 4 patients without pain (control group). Abnormal MRI findings were distributed in all groups in a balanced way, irrespective of the patients' symptoms, prostheses, or metal ion levels. Two patients from Group 1 and one patient of Group 3 (control group) were diagnosed with a large periprosthetic mass (pseudotumor).

Multiciliated cells are abundant in the epithelial surface of different tissues, including cells lining the walls of the lateral ventricles in the brain and the airway epithelium. Their main role is to control fluid flow and defects in their differentiation are implicated in many human disorders, such as hydrocephalus, accompanied by defects in adult neurogenesis and mucociliary disorder in the airway system. Here we show that Mcidas, which is mutated in human mucociliary clearance disorder, and GemC1 (Gmnc or Lynkeas), previously implicated in cell cycle progression, are key regulators of multiciliated ependymal cell generation in the mouse brain. Overexpression and knockdown experiments show that Mcidas and GemC1 are sufficient and necessary for cell fate commitment and differentiation of radial glial cells to multiciliated ependymal cells. Furthermore, we show that GemC1 and Mcidas operate in hierarchical order, upstream of Foxj1 and c-Myb transcription factors, which are known regulators of ependymal cell generation, and that Notch signaling inhibits GemC1 and Mcidas function. Our results suggest that Mcidas and GemC1 are key players in the generation of multiciliated ependymal cells of the adult neurogenic niche.

Spin periods of Be/X-ray binary (BeXRB) pulsars are important for probing their formation channels and the connection between orbital period and pulsar spin in XRBs (Knigge+ 2011). From the 120 BeXRBs in the SMC only 50% have known spin periods, with the majority of them measured during outburst with ToOs. From the remaining systems only 6 have a known orbital period. XMMU J004855.5-734946 is a BeXRB in the SMC (Haberl & Sturm 2016, XMM Lx (0.03-1)x10^35 erg/s) with a 36.43d orbital period (Atel#9198), but with no X-ray pulsations detected so far. On 06/24 a 37s Swift/XRT observation detected the system at Lx 10^37 erg/s (Atel#9197) following a marginal detection on 06/16 (Lx<5x10^36 erg/s) confirming the onset of a large outburst. A follow-up 1ks Swift ToO on 06/29 measures an Lx = 8.3x10^36 erg/s. This is a unique opportunity to measure the spin period of one of the few BeXRBs in the SMC with known orbital period but unknown spin period.

The assessment of dietary attitudes and behaviors provides information of interest to sports nutritionists. Although there has been little analysis of the quality of research undertaken in this field, there is evidence of a number of flaws and methodological concerns in some of the studies in the available literature. This review undertook a systematic assessment of the attributes of research assessing the nutritional knowledge and attitudes of athletes and coaches. Sixty questionnaire-based studies were identified by a search of official databases using specific key terms with subsequent analysis by certain inclusion–exclusion criteria. These studies were then analyzed using 33 research quality criteria related to the methods, questionnaires, and statistics used. We found that many studies did not provide information on critical issues such as research hypotheses (92%), the gaining of ethics approval (50%) or informed consent (35%), or acknowledgment of limitations in the implementation of studies or interpretation of data (72%). Many of the samples were non-probabilistic (85%) and rather small (42%). Many questionnaires were of unknown origin (30%), validity (72%), and reliability (70%) and resulted in low (≤ 60%) response rates (38%). Pilot testing was not undertaken in 67% of the studies. Few studies dealt with sample size (2%), power (3%), assumptions (7%), confidence intervals (3%), or effect sizes (3%). Improving some of these problems and deficits may enhance future research in this field.

In the case of pediatric medicinal products the selection of an appropriate and palatable liquid dosage form can make the difference between treatment success and failure. Since the recent adoption of Pediatric Regulations in the U.S. and E.U., there is a greater demand for age-appropriate medicines for children. Extended research on the use of milk on drug administration in pediatric population has shown the multiple benefits of its use. Milk exhibits great solubilizing, gastroprotective and taste masking properties, which are very important characteristics in the case of insoluble, irritating and bitter-tasting active compounds. Milk-based formulations rely on a novel, simple and user-friendly approach for the delivery of ionized and unionized lipophilic drugs. In parallel they can provide critical nutritive elements and a wide range of biologically active peptides, very important elements especially for pediatric patients. (C) 2015 Elsevier B.V.

This paper addresses the critical issue of how wrong can water resources management go if the structure and hydrodynamic evolution of the exploited system is not well known. As a case study the River Pinios estuarine groundwater system in central Greece, is discussed. The study area has a spatial extent of about 80km2 and a typical estuarine shape. Due to the neotectonic evolution and the eustatic moves, a unique geomorphological environment and a dense hydrological network have been developed. Dominant socioeconomic activity in the region is agriculture and secondarily tourism that is focused only along a narrow strip along the coastal line and occurs only seasonally. Domestic water demands are covered by groundwater abstractions mainly from deeper wells drilled at the margins of the estuarine. Shallow wells in the alluvial sediments of the basin augment irrigation demands that are predominantly catered by surface water from the river Pinios and its tributaries, and to a minor extent several springs that emerge along the marginal fans of the basin. Due to the shallow groundwater levels, a large percentage of irrigation demands is covered by direct osmosis of water from the root zone.

Mitochondria represent the major bioenergetic hub coordinating cellular and organismal homeostasis. The underlying causes of many pathologies tormenting humans converge on impaired mitochondrial maintenance. Mitochondria-specific autophagy (mitophagy), a cellular catabolic process targeting mitochondria, holds a prominent role in mitochondrial quality control. In addition to core autophagic machinery components, mitophagy exploits a variety of molecules that identify damaged or superfluous mitochondria and mediate their elimination. Signaling pathways integrating environmental and genetic stimuli interact with key mitophagy effectors to activate cellular stress response mechanisms, ultimately modulating health and lifespan. Here, we review the signaling cascades and molecular mechanisms that govern the process of mitophagy and discuss their involvement in ageing and neurodegeneration. This article is part of a Special Issue entitled: Mitochondrial Dysfunction in Aging.

Molecular typing data on antimicrobial-resistant Propionibacterium strains are limited in the literature. We examined antimicrobial resistance profiles and the underlying resistance mechanisms in Propionibacterium spp. isolates recovered from patients with moderate to severe acne vulgaris in Greece. The clonallity of the resistant Propionibacterium acnes isolates was also investigated. Propionibacterium spp. isolates were detected using Tryptone-Yeast Extract-Glucose (TYG) agar plates supplemented with 4% furazolidone. Erythromycin, clindamycin, vancomycin, penicillin, co-trimoxazole, doxycycline, minocycline and ciprofloxacin MICs were determined using the gradient strip method. Erythromycin, clindamycin and tetracycline mechanisms of resistance were determined using PCR and sequencing of the domain V of 23S rRNA and 16S rRNA, as well as the presence of the ermX gene. Typing was performed using the multi locus sequence typing (MLST) methodology. Seventy nine isolates from 76 patients were collected. Twenty-three isolates (29.1%) exhibited resistance to erythromycin and clindamycin, while two additional isolates (2.5%) were resistant only to erythromycin. Resistance to tetracycline was not detected. The underlying molecular mechanisms were point mutations A2059G and A2058G. MLST typing of the P. acnes resistant isolates revealed that lineage type IA1 (ST-1, 3 and 52) prevailed (12/18; 66.7%), whilst lineage type IA2 (ST-2 and 22) accounted for five more isolates (27.8%). Susceptible isolates were more evenly distributed between ST types. Propionibacterium spp. from moderate to severe acne vulgaris in Greece are frequently resistant to erythromycin/clindamycin but not to tetracyclines, mainly due to the point mutations A2059G and A2058G. P. acnes resistant isolates were more clonally related than susceptible ones and belonged to a limited number of MLST types.

BACKGROUND: HIV-1 subtype B is the predominant one in European regions several, while other subtypes and recombinants are also circulating with high prevalence. A sub-epidemic of subtype F with specific characteristics and low response to treatment has been recently identified in Galicia. In this study we investigated the characteristics of the HIV-1 subtype F sub-epidemic in A Coruña and Santiago de Compostela in Northwest Spain. METHODS: 420 newly HIV-1 diagnosed patients during 2009-2013 were enrolled in this study. HIV-1 subtyping was carried out using automated subtyping tools and phylogenetic analysis. Molecular epidemiology investigation of subtypes B and F was performed by means of phylogenetic analysis using fast maximum likelihood. Phylodynamic analysis was performed using Bayesian method as implemented in BEAST v1.8. RESULTS: Subtype B found to be the predominant (61.2% and 70.4%) followed by subtype F (25.6% and 12.0%) in both areas (A Coruña and Santiago de Compostela, respectively). The latter found to mainly spread among men having sex with men (MSM). The vast majority of subtype F lineages from both areas clustered monophyletically, while subtype B sequences clustered in several tree branches. The exponential growth of subtype F sub-epidemic dated back in 2008 by means of phylodynamic analysis. Most of new infections during 2009-2013 occurred within the subtype F transmission cluster. CONCLUSIONS: Subtype F circulates at high prevalence in A Coruña and Santiago de Compostela in Northwest Spain, suggesting that the HIV-1 epidemic in this region has distinct characteristics to the rest of Spain. Subtype F has being spreading among MSM and is currently the most actively spreading network. The single cluster spread of this local sub-epidemic might provide an explanation for the distinct characteristics and the low response to antiretroviral treatment.

This chapter has shown that the multiethnic harem slavery institution was the Ottoman system’s primary socialization agent and an indispensable part of its self­-reproduction. It has contributed to the discourse on sexual slavery, primarily through the first-hand accounts of western women and harem inmates of the 19th century. It has shown that multiethnic–multiracial slavery was vital for the Ottoman economy and social system and provided a means of social integration-assimilation and social mobility: status and political power. Sexual slavery was a central part of the slave system and slaves of both genders were easily integrated into Ottoman society, eventually becoming free Muslims.       Mainly through the eyes of western women and harem inmates of the 19th century, corroborating that the harem system was based on slavery, this chapter has contributed additional evidence confirming that:  firstly, the expansionist views of Islam and the institution of slavery resulted in the multiethnic composition of the Ottoman households: harems and selemliks. Secondly, an Ottoman harem— especially that of the elite and so-called middle-class—was made up of women and children from different nations: Islamized slaves, liberated slaves and descendants of slaves, including islamized eunuchs. Thirdly, the Ottoman elite was responsible for the preservation of slavery until the early 20th century and, as a result, the prolongation of polygyny and the large-scale castration of African boys, which was another dehumanizing aspect of the Ottoman slavery institution.   Acknowledgments I would like to express my gratitude to the Greek artist Areti Kamperidis for her magnificent artwork, including her exceptional paintings, inspired by the female accounts and illustrated in this article.Keywords: human trafficking, slavery, sexual slavery, social mobility, polygyny, eunuchs, children’s harem, seraglio, marriage, divorce, veiling, gender, womenWHEN CITING: Kamberidou, I.

Through the eyes of western women of the 18th and 19th centuries, this paper discusses the Ottoman slavery institution and 'the real position of women in the religious system of Islam' (Garnett 1895: 61).  Focusing on primary sources, first-hand accounts of European women travel writers, authors and journalists in Ottoman territories and principally in Asia Minor (Turkey), this article confirms that all the harem inmates were women of different nations and races: Islamized slaves, liberated slaves and descendants of slaves. Western women, in their intimate contacts with the harem inmates—free and slave—discuss the Ottoman dynasty’s reproductive politics, forced abortion, marriage, divorce, veiling or Muslim women’s attire,  slave rights and social mobility, including requirements for slave liberation. This researcher concludes that the Multiethnic-Multiracial Harem Slavery Institution was the collective segregation, confinement or enslavement of the female gender in one specific space (household/harem), as one collective identity since all the women—slave and free—shared or legally belonged to one man or master: sultan, grand vizier, vizier, pacha, etc. Keywords: slavery, sexual slavery, social mobility, polygyny, eunuchs, children’s harem, seraglio, marriage, divorce, veiling ----------------------------------------------------------------------------------------------- When citing: Kamberidou, I.

Tidal notches are a well-known sea-level indicator, marking clearly former shorelines, which have often been used to deduce Quaternary tectonic trends and sea-level changes, mainly in uplifting areas. If raised notches have often been used to estimate past changes in sea level and tectonic movements, submerged notches, which are more difficult to observe, have been studied mainly occasionally by a few authors. Nevertheless, Holocene tectonics may include more than a single episode and it may be useful to extend underwater observations below the first submerged notch. In this context, this work focuses in the Aegean region, an area characterized by extensional tectonics, where subsidence prevails, related to the subduction of the Mediterranean floor below the Hellenic arc, where Quaternary uplift trends tend to prevail. In some islands of Cyclades and Sporades, there is evidence of the occurrence of repeated rapid subsidences during the Late Holocene. In this paper, the shape of tidal notches that may well be preserved underwater is recalled in order to reconstruct sequences of coseismic subsidences and other relative sea-level changes that occurred during at least the last few millennia. A re-analysis of already published measurements of submerged tidal notches in several islands reveals that subsidence trends in many areas of the Aegean are not continuous and gradual, but the result of repeated coseismic vertical subsidences of some decimetres at each time. The estimated average return times are of the order of approximately some centuries to one millennium. Although the results cannot be used for short-term predictions of earthquakes, they may provide useful indications about the long-term tectonic trends that are active in the Aegean region.

Muscle LIM Protein (MLP) has emerged as a key regulator of striated muscle physiology and pathophysiology. Mutations in cysteine and glycine-rich protein 3 (CSRP3), the gene encoding MLP, are causative of human cardiomyopathies, whereas altered expression patterns are observed in human failing heart and skeletal myopathies. In vitro and in vivo evidences reveal a complex and diverse functional role of MLP in striated muscle, which is determined by its multiple interacting partners and subcellular distribution. Experimental evidence suggests that MLP is implicated in both myogenic differentiation and myocyte cytoarchitecture, although the full spectrum of its intracellular roles still unfolds.

The aim of the study was to compare the effects of compound vs. complex resistance training on strength, high-speed movement performance, and muscle composition. Eighteen young men completed compound (strength and power sessions on alternate days) or complex training (strength and power sets within a single session) 3 times per week for 6 weeks using bench press, leg press, Smith machine box squat, and jumping exercises. Pre- and posttraining, jumping and throwing performance and maximum bench press, leg press, and Smith machine box squat strength were evaluated. The architecture of vastus lateralis and gastrocnemius muscle was assessed using ultrasound imaging. Vastus lateralis morphology was assessed from muscle biopsies. Jumping (4 ± 3%) and throwing (9 ± 8%) performance increased only with compound training (p < 0.02). Bench press (5 vs. 18%), leg press (17 vs. 28%), and Smith machine box squat (27 vs. 35%) strength increased after both compound and complex training. Vastus lateralis thickness and fascicle angle and gastrocnemius fascicle angle were increased with both compound and complex training. Gastrocnemius fascicle length decreased only after complex training (-11.8 ± 9.4%, p = 0.006). Muscle fiber cross-sectional areas increased only after complex training (p ≤ 0.05). Fiber type composition was not affected by either intervention. These results suggest that short-term strength and power training on alternate days is more effective for enhancing lower-limb and whole-body power, whereas training on the same day may induce greater increases in strength and fiber hypertrophy.

BACKGROUND: There is sparse evidence that demonstrates the association between macro-environmental processes and drug-related HIV epidemics. The present study explores the relationship between economic, socio-economic, policy and structural indicators, and increases in reported HIV infections among people who inject drugs (PWID) in the European Economic Area (EEA). METHODS: We used panel data (2003-2012) for 30 EEA countries. Statistical analyses included logistic regression models. The dependent variable was taking value 1 if there was an outbreak (significant increase in the national rate of HIV diagnoses in PWID) and 0 otherwise. Explanatory variables included the growth rate of Gross Domestic Product (GDP), the share of the population that is at risk for poverty, the unemployment rate, the Eurostat S80/S20 ratio, the Gini coefficient, the per capita government expenditure on health and social protection, and variables on drug control policy and drug-using population sizes. Lags of one to three years were investigated. FINDINGS: In multivariable analyses, using two-year lagged values, we found that a 1% increase of GDP was associated with approximately 30% reduction in the odds of an HIV outbreak. In GDP-adjusted analyses with three-year lagged values, the effect of the national income inequality on the likelihood of an HIV outbreak was significant [S80/S20 Odds Ratio (OR) = 3.89; 95% Confidence Interval (CI): 1.15 to 13.13]. Generally, the multivariable analyses produced similar results across three time lags tested. INTERPRETATION: Given the limitations of ecological research, we found that declining economic growth and increasing national income inequality were associated with an elevated probability of a large increase in the number of HIV diagnoses among PWID in EEA countries during the last decade. HIV prevention may be more effective if developed within national and European-level policy contexts that promote income equality, especially among vulnerable groups.

BACKGROUND: There is sparse evidence that demonstrates the association between macro-environmental processes and drug-related HIV epidemics. The present study explores the relationship between economic, socio-economic, policy and structural indicators, and increases in reported HIV infections among people who inject drugs (PWID) in the European Economic Area (EEA). METHODS: We used panel data (2003-2012) for 30 EEA countries. Statistical analyses included logistic regression models. The dependent variable was taking value 1 if there was an outbreak (significant increase in the national rate of HIV diagnoses in PWID) and 0 otherwise. Explanatory variables included the growth rate of Gross Domestic Product (GDP), the share of the population that is at risk for poverty, the unemployment rate, the Eurostat S80/S20 ratio, the Gini coefficient, the per capita government expenditure on health and social protection, and variables on drug control policy and drug-using population sizes. Lags of one to three years were investigated. FINDINGS: In multivariable analyses, using two-year lagged values, we found that a 1% increase of GDP was associated with approximately 30% reduction in the odds of an HIV outbreak. In GDP-adjusted analyses with three-year lagged values, the effect of the national income inequality on the likelihood of an HIV outbreak was significant [S80/S20 Odds Ratio (OR) = 3.89; 95% Confidence Interval (CI): 1.15 to 13.13]. Generally, the multivariable analyses produced similar results across three time lags tested. INTERPRETATION: Given the limitations of ecological research, we found that declining economic growth and increasing national income inequality were associated with an elevated probability of a large increase in the number of HIV diagnoses among PWID in EEA countries during the last decade. HIV prevention may be more effective if developed within national and European-level policy contexts that promote income equality, especially among vulnerable groups.

BACKGROUND: Greece experienced an unprecedented increase in HIV cases among drug injectors in 2011 after economic crisis. Network-level factors are increasingly understood to drive HIV transmission in emerging epidemics. METHODS: We examined the relationship between networks, risk behaviors, and HIV serostatus among 1404 people who inject drugs in Athens, Greece. We generated networks using the chain-referral structure within a large HIV screening program. Network proportions, the proportion of a respondent's network with a given characteristic, were calculated. Multiple logistic regression models were used to assess the relationship between network proportions and individual HIV seroprevalence, injection frequency and unprotected sex. RESULTS: Of note, 1030 networks were generated. Respondent HIV seroprevalence was associated with greater proportions of network members who were HIV infected (ie, those with >/= 50% of network members HIV positive vs. those with no network members HIV positive) (AOR: 3.11; 95% CI: 2.10 to 4.62), divided drugs (AOR: 1.60; 95% CI: 1.10 to 2.35), or injected frequently (AOR: 1.50; 95% CI: 1.02 to 2.21). Homelessness was the only sociodemographic characteristic associated with a risk outcome measure--high-frequency injecting (AOR: 1.41; 95% CI: 1.03 to 1.93). These associations were weaker for more distal second- and third-degree networks and not present when examined within random networks. CONCLUSIONS: Networks are an independently important contributor to the HIV outbreak in Athens, Greece. Network associations were strongest for the immediate network, with residual associations for distal networks. Homelessness was associated with high-frequency injecting. Prevention programs should consider including network-level interventions to prevent future emerging epidemics.

The purpose of our study was to summarize all the knowledge concerning the innovative pioneer in the field of orthopaedic surgery, Nicholas J. Giannestras (1908-1978). A thorough study of texts, medical books and reports, in the field of history of medicine, together with a review of the available literature in PubMed, was undertaken. Giannestras left his mark in the history of orthopaedics with his clinical work and his publications, mainly his treatise "Foot Disorders: Medical and Surgical Management" (1973), while his name lingers in Greece with the introduction of spine fusion with the use of metallic implants. He was an eminent university clinical professor of orthopaedics who had harmonically combined academic writing, teaching and clinical research in every field of orthopaedic surgery.

BACKGROUND: Age-related macular degeneration (AMD) is a degenerative ocular disease, which may lead to loss of central vision. In Caucasian populations, a strong correlation has been established with polymorphism Y402H (rs1061170) in the complement factor H gene (CFH). The H131R polymorphism (rs1801274) in the FCGR2A gene has been associated with many inflammatory diseases, but has not been investigated in relation to AMD. The goal of our study was the development of a novel method for Y402H (g.43097C>T) genotyping, the confirmation of its association with AMD in the Greek population and the investigation of the H131R polymorphism in AMD. METHODS: DNAs were extracted from blood samples of 120 patients with the severe wet form of AMD and 103 age- and sex-matched controls, all of whom were clinically evaluated. A real-time PCR and melting curve analysis method for Y402H genotyping was developed in the LightCycler platform, after in silico design of appropriate primers and probes. Genotyping for H131R was performed using a real-time PCR method previously described by our group. RESULTS: The novel genotyping method for Y402H in the CFH gene is fast, reproducible (Efficiency=1.79, reproducibility CVCq=3.33%, Tm C allele 53.36 degrees C and T allele 61.91 degrees C, DeltaTm=8.55) and accurate as results were confirmed with the gold standard DNA Sequencing method. CONCLUSIONS: The present study confirmed the association between CFH Y402H SNP and wet AMD in the Greek population (OR=1.77, p=0.002). FCGR2A H131R polymorphism was investigated for the first time in this present study for possible correlation with wet AMD and a statistically significant association was detected (OR=1.74, p=0.006), that awaits further confirmation in a larger set of samples

OBJECTIVES: Chewing efficiency may be evaluated using cohesive specimen, especially in elderly or dysphagic patients. The aim of this study was to evaluate three two-coloured chewing gums for a colour-mixing ability test and to validate a new purpose built software (ViewGum©). METHODS: Dentate participants (dentate-group) and edentulous patients with mandibular two-implant overdentures (IOD-group) were recruited. First, the dentate-group chewed three different types of two-coloured gum (gum1-gum3) for 5, 10, 20, 30 and 50 chewing cycles. Subsequently the number of chewing cycles with the highest intra- and inter-rater agreement was determined visually by applying a scale (SA) and opto-electronically (ViewGum©, Bland-Altman analysis). The ViewGum© software determines semi-automatically the variance of hue (VOH); inadequate mixing presents with larger VOH than complete mixing. Secondly, the dentate-group and the IOD-group were compared. RESULTS: The dentate-group comprised 20 participants (10 female, 30.3±6.7 years); the IOD-group 15 participants (10 female, 74.6±8.3 years). Intra-rater and inter-rater agreement (SA) was very high at 20 chewing cycles (95.00-98.75%). Gums 1-3 showed different colour-mixing characteristics as a function of chewing cycles, gum1 showed a logarithmic association; gum2 and gum3 demonstrated more linear behaviours. However, the number of chewing cycles could be predicted in all specimens from VOH (all p<0.0001, mixed linear regression models). Both analyses proved discriminative to the dental state. CONCLUSION: ViewGum© proved to be a reliable and discriminative tool to opto-electronically assess chewing efficiency, given an elastic specimen is chewed for 20 cycles and could be recommended for the evaluation of chewing efficiency in a clinical and research setting. CLINICAL SIGNIFICANCE: Chewing is a complex function of the oro-facial structures and the central nervous system. The application of the proposed assessments of the chewing function in geriatrics or special care dentistry could help visualising oro-functional or dental comorbidities in dysphagic patients or those suffering from protein-energy malnutrition.

Valid characterization of carotid atherosclerosis (CA) is a crucial public health issue, which would limit the major risks held by CA for both patient safety and state economies. This paper investigated the unexplored potential of kinematic features in assisting the diagnostic decision for CA in the framework of a computer-aided diagnosis (CAD) tool. To this end, 15 CAD schemes were designed and were fed with a wide variety of kinematic features of the atherosclerotic plaque and the arterial wall adjacent to the plaque for 56 patients from two different hospitals. The CAD schemes were benchmarked in terms of their ability to discriminate between symptomatic and asymptomatic patients and the combination of the Fisher discriminant ratio, as a feature-selection strategy, and support vector machines, in the classification module, was revealed as the optimal motion-based CAD tool. The particular CAD tool was evaluated with several cross-validation strategies and yielded higher than 88% classification accuracy; the texture-based CAD performance in the same dataset was 80%. The incorporation of kinematic features of the arterial wall in CAD seems to have a particularly favorable impact on the performance of image-data-driven diagnosis for CA, which remains to be further elucidated in future prospective studies on large datasets.

abstract extra virgin olive oil contains significant quantities of polar phenolic ingredients. The large majority is made up of esters of tyrosol or hydroxytyrosol with secoiridoid derivatives from oleuropein or ligstroside. in the current study we describe a number of new or incompletely characterized forms of ligstroside and oleuropein aglycons. two of them which are stable enolic forms are described for the first time as real olive oil ingredients although their presence in olive oil had been postulated. to minimize the confusion with the complicated names of the agly-con isomers we propose the names oleokoronal and oleomissional for the two ingredients. after screening 2000 samples of olive oil from most major varieties we were able to identify samples of olive oil in which oleokoronal and oleomissional were the major phenolic ingredients and could be used as starting material for their isolation. interestingly, during normal or reversed phase chromatography both compounds were transformed to the known forms of monoaldehydic closed ring aglycons, which offers an explanation as to why those compounds had not been identified so far. Their real presence in olive oil was confirmed by direct nMr observation without the use of any solvent.

Central to the process of transmembrane cargo trafficking is the successful folding and exit from the ER through packaging in COPII vesicles. Here, we use the UapA purine transporter of Aspergillus nidulans to investigate the role of cargo oligomerization in membrane trafficking. We show that UapA oligomerizes (at least dimerizes) and that oligomerization persists upon UapA endocytosis and vacuolar sorting. Using a validated BiFC assay, we provide evidence that a UapA oligomerization is associated with ER exit and turnover, as ER-retained mutants, either due to modification of a Tyr-based N-terminal motif or partial misfolding, physically associate, but do not associate properly. Co-expression of ER-retained mutants with wild-type UapA leads to in trans plasma membrane localization of the former, confirming that oligomerization initiates in the ER. Genetic suppression of an N-terminal mutation in the Tyr motif and mutational analysis suggest that transmembrane α-helix 7 affects the oligomerization interface. Our results reveal that transporter oligomerization is essential for membrane trafficking and turnover and is a common theme in fungi and mammalian cells.

BACKGROUND: Atherosclerotic lesions at the origin of common carotid, subclavian, and innominate arteries are causes for brain and hand ischemic symptoms. Surgical reconstructions of symptomatic cases remain the golden standard treatment, although the endovascular approach has been promising as well. In this retrospective study, long-term results of open reconstructions from 2 University Hospitals are presented. METHODS: Through a 30-year period, prospective data of 107 patients, suffering from symptomatic atherosclerotic supra-aortic artery disease, were retrospectively reviewed and included in this study. Demographic data, arterial risk factors, presenting symptoms and signs, diagnostic evaluation, operative treatment and complications, resolution of symptoms, redo surgery, and overall mortality were analyzed. RESULTS: Eighty-one patients were operated on for subclavian, 14 for innominate, and 12 for common carotid severe lesions, through an extra-thoracic reconstruction (91 patients) or a transthoracic one (16 patients). Perioperative mortality was null although morbidity was 16.8%, and primary perioperative patency was 97.2% (secondary patency 100%). The cumulative primary patency was 95.3%, 90.7%, and 86.0% at 5, 10, and 15 years, respectively. The mean time of patency was 214.6 months (95% confidence interval = 198.5-230.6), with no difference between transthoracic and extrathoracic reconstructions (P = 0.278). CONCLUSIONS: Open reconstructions remain a therapeutic strategy with a considerably low perioperative morbidity/mortality offering excellent long-term results regarding patency of the reconstructions and clinical resolution of the symptoms. However, in the modern era of the endovascular techniques, we need more studies for establishing anatomic and clinical criteria regarding patient selection for endovascular angioplasty/stenting or open repair.

V404 Cyg is a known black hole Low mass X-ray binary with a late G-type companion, having a ~6.5 d orbital period. On June 15 18:32 UT Swift Burst Alert Telescope (BAT) was triggered due to the high X-ray activity of the system (Barthelmy et al.

A puzzling, slightly submerged, single tidal notch has been reported from the carbonate coasts of the northeastern Adriatic Sea. This paper attempts to explain the origin and the recent evolution of this marine erosion feature and the reasons for its uniqueness in the late Holocene. After reviewing how tidal notches are usually formed, a comparison of recent measurements of bioerosion rates carried out in the area show that when the contribution of dissolution processes can be neglected, bioerosion rates of the deepening of tidal-notch profiles appear to be very low (often <0.1 mm/y) along the coasts of Istria, in contrast to higher rates (between 0.2 and 1.0 mm/y) generally reported in other Mediterranean areas. Such a low rate of bioerosion implies a long period favourable to tidal-notch development. Several glacial isostatic adjustment computations show that relative sea level changes in the area during the last few millennia may correspond to a period of equilibrium between the regional tectonic subsidence and hydro-isostatic emergence during which relative sea level changes were limited, permitting development of the tidal notch observed. The submergence of the notch is consistent with a coseismic subsidence in late Roman time. After this, a new tidal notch could not form at the present sea level because of the limited amount of local bioerosion and the relatively large rate of sea level rise.

NCS1 proteins are H(+) /Na(+) symporters specific for the uptake of purines, pyrimidines and related metabolites. In this article we study the origin, diversification and substrate specificity of fungal NCS1 transporters. We show that the two fungal NCS1 subfamilies, Fur and Fcy, and plant homologues, originate through independent horizontal transfers from prokaryotes, and that expansion by gene duplication led to the functional diversification of fungal NCS1. We characterized all Fur proteins of the model fungus Aspergillus nidulans and discovered novel functions and specificities. Homology modelling, substrate docking, molecular dynamics and systematic mutational analysis in three Fur transporters with distinct specificities identified residues critical for function and specificity, located within a major substrate binding site, in transmembrane segments TMS1, TMS3, TMS6 and TMS8. Most importantly, we predict and confirm that residues determining substrate specificity are located not only in the major substrate binding site, but also in a putative outward-facing selective gate. Our evolutionary and structure-function analysis contributes in the understanding of the molecular mechanisms underlying the functional diversification of eukaryotic NCS1 transporters, and in particular, forward the concept that selective channel-like gates might contribute to substrate specificity.

Bone metabolism has not been systematically studied in primary (AL) amyloidosis. Thus we prospectively evaluated bone remodeling indices in 102 patients with newly diagnosed AL amyloidosis, 35 healthy controls, 35 newly diagnosed myeloma and 40 monoclonal gammopathy of undetermined significance patients. Bone resorption markers (C-telopeptide of type-1 collagen, N-telopeptide of type-1 collagen) and osteoclast regulators (soluble receptor activator of nuclear factor-κB ligand (sRANKL), osteoprotegerin (OPG)) were increased in AL patients compared with controls (P<0.01), but bone formation was unaffected. Myeloma patients had increased bone resorption and decreased bone formation compared with AL patients, while sRANKL/OPG ratio was markedly decreased in AL, due to elevated OPG in AL (P<0.001). OPG correlated with N-terminal pro-brain natriuretic peptide (P<0.001) and was higher in patients with cardiac involvement (P=0.028) and advanced Mayo stage (P=0.001). OPG levels above the upper value of healthy controls was associated with shorter survival (34 versus 91 months; P=0.026), while AL patients with OPG levels in the top quartile had very short survival (12 versus 58 months; P=0.024). In Mayo stage 1 disease, OPG identified patients with poor survival (12 versus >60 months; P=0.012). We conclude that increased OPG in AL is not only a compensation to osteoclast activation but may also reflect early cardiac damage and may identify patients at increased risk of death within those with earlier Mayo stage.

We conclude that increased OPG in AL is not only a compensation to osteoclast activation but may also reflect early cardiac damage and may identify patients at increased risk of death within those with earlier Mayo stage.

INTRODUCTION: Heart failure (HF) treatment attracts a share of intensive research because of its poor HF prognosis. In the past decades, the prognosis of HF has improved considerably, mainly as a consequence of the progress that has been made in the pharmacological management of HF. AREAS COVERED: This article reviews the outpatient pharmacological management of chronic HF due to left ventricular systolic dysfunction and offers recommendations on the use of various drugs. In addition, the present article attempts to provide practical therapeutic algorithms based on current clinical strategies. EXPERT OPINION: Continued research directed toward identifying factors associated with high pharmacotherapy guideline adherence and understanding of variants that influence response to drugs will hopefully halt or reverse the major pathophysiological mechanisms involved in this syndrome.

Summary: In the phase III MM-003 trial, pomalidomide plus low-dose dexamethasone (POM+LoDEX) improved overall survival (OS) versus high-dose dexamethasone (HiDEX) in 455 patients with relapsed and refractory multiple myeloma (RRMM) after treatment with bortezomib and lenalidomide. Here, a two-stage Weibull method was used to adjust for the crossover of patients in the HiDEX arm to pomalidomide-based therapy. The adjusted difference in median OS between patients in the POM+LoDEX and HiDEX arms was 7·0 months (12·7 vs. 5·7 months, respectively). These findings provide important evidence for understanding the clinical efficacy of pomalidomide on OS benefits seen in RRMM patients. © 2014 John Wiley & Sons Ltd.

PURPOSE: The identification of childhood acute lymphoblastic leukemia (ch-ALL) patients who are at a higher risk of chemotherapy resistance and relapse is essential for successful treatment decisions, despite the application of novel therapies. The aim of the study is the evaluation of BCL2 and BAX expression for the prognosis of ch-ALL patients treated with Berlin-Frankfurt-Munster (BFM) backbone protocol. METHODS: Bone marrow specimens were obtained at the time of diagnosis and on day 33 following BFM treatment induction from 82 ch-ALL patients, as well as from 63 healthy children. Following extraction, total RNA was reverse transcribed and BCL2 and BAX expression levels were determined by qPCR. RESULTS: BCL2 expression and BCL2/BAX ratio were strongly upregulated in ch-ALL compared to healthy children and were correlated with favorable prognostic disease features. Increased levels of BCL2 and BAX expression were associated with disease remission, as ch-ALL patients with lower expression ran a significantly higher risk of M2-M3 response, positive MRD and poor survival outcome. Moreover, the upregulation of BCL2 and BAX following BFM treatment induction was shown to represent an independent predictor of patients' short-term relapse, which was further confirmed in ch-ALL patients with favorable prognostic markers. CONCLUSIONS: In conclusion, BCL2 and BAX could be effectively used for an enhanced prediction of BFM-treated patients' outcome.

Oxidative stress refers to cellular or molecular damage caused by reactive oxygen species, which especially occurs in age-related conditions as a result of an imbalance between the production of reactive oxygen species and the antioxidant defense response. Dry age-related macular degeneration (AMD) and exfoliation syndrome (XFS) are two common and complex age-related conditions that can cause irreversible vision loss. Two subtypes of AMD, which is the leading cause of blindness in the Western world, exist: the most prevalent dry type and the most severe wet type. Early dry AMD is characterized by formation of drusen, which are sub-retinal deposits, in the macular area and may progress to geographic atrophy with more dramatic manifestation. XFS is a systemic disorder of the extracellular matrix characterized by the accumulation of elastic fibrils that leads, in most cases, to glaucoma development with progressive and irreversible vision loss. Due to the aging population, the prevalence of these already-widespread conditions is increasing and is resulting in significant economic and psychological costs for individuals and for society. The exact composition of the abnormal drusen and XFS material as well as the mechanisms responsible for their production and accumulation still remain elusive, and consequently treatment for both diseases is lacking. However, recent epidemiologic, genetic and molecular studies support a major role for oxidative stress in both dry AMD and XFS development. Understanding the early molecular events in their pathogenesis and the exact role of oxidative stress may provide novel opportunities for therapeutic intervention for the prevention of progression to advanced disease

Important earthquakes are often accompanied by vertical-land displacements. Therefore in coastal areas they may result in rapid changes of the relative sea level. An essential tool for the study of coastal paleoseismicity is the identification of fossil paleoshorelines, paying special attention to sea-level indicators that are consistent or provide evidence of rapid relative sea-level change.Here, different types of sea-level indicators that are often used in literature in order to determine changes in fossil shorelines are summarized. Information is also provided regarding four case studies of important earthquakes that occurred in Greece (in AD 365, 1953, and 1956) and in Japan (in 1923).

Paleoceanographic proxies, such as marine micropaleontology, sedimentology and organic geochemistry havebeen performed in the sediment record of SK-3 gravity core (total length 217cm, water depth 249m) in order toprovide possible determination of late interglacial-Holocene the paleoenvironmental changes, at the southwestern margin of Cyclades plateau in the SW Aegean Sea. The sediment core exhibits two sapropels layer; thefirst one is associated with sapropel S1. The second sapropelic layer which we focus on represents anoxicconditions during the high sea-level warm event associated with sapropel S5 deposition.

Detailed pollen analyses were performed at the lower sapropelic deposits of the marine core SK-3 within theframework of a multiproxy palaeoceanographic-palaeoenvironmental study. Pollen flora is characterized byhigh arboreal pollen abundances, mainly deciduous Quercus, together with Pinus, Juniperus and otherdeciduous taxa. A transition is marked from vegetation where Mediterranean elements appear more abundanttowards mixed deciduous woodland. In the upper part of the deposits an expansion of Abies, Pinus and Fagushas been recorded. The overall vegetation pattern adds significant evidence about the terrestrialpalaeoenvironmental conditions during deposition of sapropel S5.

Insulinomas are rare pancreatic neuroendocrine tumors that are most commonly benign, solitary, and intrapancreatic. Uncontrolled insulin overproduction from the tumor produces neurological and adrenergic symptoms of hypoglycemia. Biochemical diagnosis is confirmed by the presence of Whipple's triad, along with corroborating measurements of blood glucose, insulin, proinsulin, C-peptide, β-hydroxybutyrate, and negative tests for hypoglycemic agents during a supervised fasting period. This is accompanied by accurate preoperative localization using both invasive and non-invasive imaging modalities. Following this, careful preoperative planning is required, with the ensuing procedure being preferably carried out laparoscopically. An integral part of the laparoscopic approach is the application of laparoscopic intraoperative ultrasound, which is indispensable for accurate intraoperative localization of the lesion in the pancreatic region. The extent of laparoscopic resection is dependent on preoperative and intraoperative findings, but most commonly involves tumor enucleation or distal pancreatectomy. When performed in an experienced surgical unit, laparoscopic resection is associated with minimal mortality and excellent long-term cure rates. Furthermore, this approach confers equivalent safety and efficacy rates to open resection, while improving cosmesis and reducing hospital stay. As such, laparoscopic resection should be considered in all cases of benign insulinoma where adequate surgical expertise is available.

Outcomes for patients with multiple myeloma (MM) have improved significantly over the past decade. Despite these advances, MM remains incurable and an unmet medical need remains for patients who are relapsed and/or refractory. Panobinostat is a potent, oral pan-deacetylase inhibitor that elicits anti-myeloma activity through epigenetic modulation of gene expression and disruption of protein metabolism. Preclinical data demonstrated that panobinostat has synergistic effects on myeloma cells when combined with bortezomib and dexamethasone. In a Phase III clinical trial evaluating bortezomib and dexamethasone in combination with panobinostat or placebo in patients with relapsed or relapsed and refractory MM (PANORAMA 1), panobinostat led to a significant increase in median progression-free survival. Panobinostat is currently under regulatory review with a recent accelerated approval granted for the treatment of relapsed disease, in which both bortezomib and immunomodulatory drugs have failed. Here, we summarize the preclinical, pharmacokinetic and clinical data for panobinostat in MM. © 2015 Informa UK, Ltd.

BACKGROUND: Besides the vast success and reliability of lower extremity joint replacement, deep and periprosthetic infection remains a serious complication of such operations. Many publications addressing periprosthetic infection have remarked about this "devastating" complication, with a risk around 1% after total hip arthroplasty and between 1% and 2% after total knee arthroplasty. The purpose of this study is to assess current trends in prevention of contamination with improved up-to-date pre-operative skin preparation methods and intra-operative draping. METHODS: A literature review was conducted in MEDLINE, Web of Science, and the Cochrane database, looking for high-quality papers summarizing the most widely held and up-to-date concepts of perioperative measures for reducing infection, focusing on the best available evidence concerning skin preparation for joint arthroplasty (THR and THR) and surgical draping. RESULTS: Current evidence suggests the use of alcohol solutions for pre-operative painting with emphasis on the use of chlorhexidine gluconate solutions beginning the night before surgery. Hair removal should be performed in the operating room with electric clippers, not razor blades. In order to enhance drape adhesion to the skin, the use of iodophor-in-alcohol solutions is recommended over the traditional scrub-and-paint technique. Disposable non-woven drapes are superior to reusable woven cotton/linen drapes in resisting bacterial penetration. Finally, the use of adherent plastic adhesive incision drapes for the prophylaxis of post-operative surgical site infections is considered not necessary in orthopedic surgery. CONCLUSIONS: The importance of skin preparation and adequate and reliable draping cannot be overemphasized for infection prevention, especially in clean operations such as THR and TKR. Thorough and strict protocols are mandatory for every department, as well as education curricula for operating room personnel. Further randomized studies are mandatory to specify the effect of the above measures, their pitfalls, and their improvement, along with further crucial details such as cost-benefit analysis of different pre-operative preparations in preventing infections.

A publicity campaign run in Athens by the Alexander S. Onassis Public Benefit Foundation in October 2013 in order to advertise its acquisition of the Cavafy Archive, until then lying in relevant obscurity, turned into a media disaster when critics and members of the public protested against what they argued was a misquoting of the highly revered Alexandrian. In this paper, I am looking at this rather entertaining story of misunderstood intentions in order to suggest that even though Cavafy himself may be shown to have enjoyed history as fragmented experience, and despite the fact that the modern archive is one of often conflicting partialities rather than one of completeness, we, as consumers of Cavafy’s oeuvre, tend to sustain his long-established position as a paragon of Greek culture, canonised through his own nonconformity.

We compared the safety and efficacy of siltuximab (S), an anti-interleukin-6 chimeric monoclonal antibody, plus bortezomib (B) with placebo (plc) + B in patients with relapsed/refractory multiple myeloma in a randomized phase 2 study. Siltuximab was given by 6 mg/kg IV every 2 weeks. On progression, B was discontinued and high-dose dexamethasone could be added to S/plc. Response and progression-free survival (PFS) were analyzed pre-dexamethasone by European Group for Blood and Marrow Transplantation (EBMT) criteria. For the 281 randomized patients, median PFS for S + B and plc + B was 8.0 and 7.6 months (HR 0.869, P = 0.345), overall response rate was 55 versus 47% (P = 0.213), complete response rate was 11 versus 7%, and median overall survival (OS) was 30.8 versus 36.8 months (HR 1.353, P = 0.103). Sustained suppression of C-reactive protein, a marker reflective of inhibition of interleukin-6 activity, was seen with S + B. Siltuximab did not affect B pharmacokinetics. Siltuximab/placebo discontinuation (75 versus 66%), grade ≥3 neutropenia (49 versus 29%), thrombocytopenia (48 versus 34%), and all-grade infections (62 versus 49%) occurred more frequently with S + B. The addition of siltuximab to bortezomib did not appear to improve PFS or OS despite a numerical increase in response rate in patients with relapsed or refractory multiple myeloma. © 2014 Wiley Periodicals, Inc.

The recent IceCube discovery of 0.1-1 PeV neutrinos of astrophysical origin opens up a new era for high-energy astrophysics. Although there are various astrophysical candidate sources, a firm association of the detected neutrinos with one (or more) of them is still lacking. A recent analysis of plausible astrophysical counterparts within the error circles of IceCube events showed that likely counterparts for nine of the IceCube neutrinos include mostly BL Lacs, among which Mrk 421. Motivated by this result and a previous independent analysis on the neutrino emission from Mrk 421, we test the BL Lac-neutrino connection in the context of a specific theoretical model for BL Lac emission. We model the spectral energy distribution (SED) of the BL Lacs selected as counterparts of the IceCube neutrinos using a one-zone leptohadronic model and mostly nearly simultaneous data. The neutrino flux for each BL Lac is self-consistently calculated, using photon and proton distributions specifically derived for every individual source. We find that the SEDs of the sample, although different in shape and flux, are all well fitted by the model using reasonable parameter values. Moreover, the model-predicted neutrino flux and energy for these sources are of the same order of magnitude as those of the IceCube neutrinos. In two cases, namely Mrk 421 and 1H 1914-194, we find a suggestively good agreement between the model prediction and the detected neutrino flux. Our predictions for all the BL Lacs of the sample are in the range to be confirmed or disputed by IceCube in the next few years of data sampling.

The Neolithic settlement of Dispilió (lake Orestiás, northern Greece) is a unique site due to its continual inhabitation from the Middle Neolithic (5400 BC) to the Chalcolithic (3600 BC) and its exceptional location at the shore of Lake Orestiás (also known as Lake Kastoria). The plant landscape shaping of the area has been examined by correlating pollen and non-pollen palynomorphs (NPPs) from both on-site and off-site records. The examined pollen profiles bear concrete evidence of agricultural activities and land use in the area. The local pollen assemblages identified, each of them corresponding either to a different kind or intensity of exploitation of natural resources, display the diachronic evolution of the cultural landscape during more than 2000 years of human activity. The successive phases of intense human impact on vegetation patterns are in good accordance with the periods of major constructing activities described by the archaeological study of the Dispilió settlement. Finally, the differences on palynomorph accumulation pathways of the examined records made possible the distinction between local and “regional” plant landscapes and related human activities.

The polycystins PC1 and PC2 are emerging as major players in mechanotransduction, a process that influences all steps of the invasion/metastasis cascade. We hypothesized that PC1 and PC2 facilitate cancer aggressiveness. Immunoblotting, RT-PCR, semi-quantitative and quantitative real-time PCR and FACS analyses were employed to investigate the effect of polycystin overexpression in colorectal cancer (CRC) cells. The impact of PC1 inhibition on cancer-cell proliferation was evaluated through an MTT assay. In vitro data were analyzed by Student's t-test. HT29 human xenografts were treated with anti-PC1 (extracellular domain) inhibitory antibody and analyzed via immunohistochemistry to determine the in vivo role of PC1 in CRC. Clinical significance was assessed by examining PC1 and PC2 protein expression in CRC patients (immunohistochemistry). In vivo and clinical data were analyzed by non-parametric tests, Kaplan-Meier curves, log-rank test and Cox model. All statistical tests were two-sided. PC1 overexpression promotes epithelial-to-mesenchymal transition (EMT) in HCT116 cells, while PC2 overexpression results in upregulation of the mTOR pathway in SW480 cells. PC1 inhibition causes reduced cell proliferation in CRC cells inducing tumor necrosis and suppressing EMT in HT29 tumor xenografts. In clinical study, PC1 and PC2 overexpression associates with adverse pathological parameters, including invasiveness and mucinous carcinomas. Moreover, PC1 overexpression appears as an independent prognostic factor of reduced recurrence-free survival (HR = 1.016, p = 0.03) and lowers overall survival probability, while aberrant PC2 expression predicts poor overall survival (p = 0.0468). These results support, for the first time, a direct link between mechanosensing polycystins (PC1 and PC2) and CRC progression.

Pomalidomide is a distinct immunomodulatory agent with significant activity in relapsed/refractory multiple myeloma (RRMM). The optimal treatment schedule in patients with RRMM who have received multiple lines of treatment, including bortezomib and lenalidomide, is 4 mg/day on days 1-21 of a 28-day cycle in combination with weekly low-dose dexamethasone. Improved responses and outcomes relative to traditional therapies continue to be confirmed in recently completed and ongoing trials. Pomalidomide exhibits direct tumoricidal, immunomodulatory, anti-angiogenic and anti-inflammatory activities, which facilitate combination therapy with agents with complementary mechanisms of action, resulting in greater anti-myeloma effects than single-agent therapy or previous combination therapies. For example, in combination with proteasome inhibitors and traditional chemotherapeutic agents in doublet or triplet regimens, pomalidomide provides high rates of durable response, and represents an important new treatment option for patients with RRMM requiring effective new therapies. Additionally, pomalidomide maintains its efficacy and tolerability profile in difficult-to-treat patients, including the elderly, patients with poor cytogenetics and those with renal impairment. This review summarises the clinical development of pomalidomide and discusses this effective agent for the treatment of patients with RRMM in the context of current myeloma treatment options, as well as potential future directions to further improve patient outcomes.

Background Health-related quality of life (HRQoL) is an important element for consideration in treatment decisions in patients with relapsed/refractory multiple myeloma (RRMM). The pivotal MM-003 (A Phase 3, Multicenter, Randomized, Open-Label Study to Compare the Efficacy and Safety of Pomalidomide in Combination With Low-Dose Dexamethasone vs. High-Dose Dexamethasone in Patients With Refractory Multiple Myeloma or Relapsed and Refractory Multiple Myeloma and Companion Study [NIMBUS]) randomized, open-label, multicenter, phase III trial demonstrated improved progression-free survival (PFS) and prolonged overall survival (OS) with pomalidomide (POM) plus low-dose dexamethasone (POM + LoDEX) versus high-dose dexamethasone (HiDEX) in patients with RRMM in whom lenalidomide (LEN) and bortezomib (BORT) had failed. MM-003 also investigated HRQoL as a predefined secondary end point. Patients and Methods Recruited patients (n = 455) were refractory to their last treatment and had failed LEN and BORT after ≥ 2 consecutive cycles of each (alone or in combination). Eight clinically relevant and validated HRQoL domains from the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30, EORTC QLQ-MY20, and EQ-5D questionnaires were selected for analysis. Time to symptom worsening based on minimally important differences (MIDs) was calculated. Results Clinically meaningful improvements in HRQoL as determined by MIDs, regression analyses, and best response analyses were observed more frequently in patients receiving POM + LoDEX than in those receiving HiDEX. POM + LoDEX significantly extended median time to clinically meaningful worsening in HRQoL versus HiDEX in 4 HRQoL domains and demonstrated a trend in an additional 3 domains. Patients in the HiDEX arm experienced earlier HRQoL deterioration compared with those in the POM + LoDEX arm in each domain analyzed. Conclusion POM + LoDEX offer good clinical outcomes that lead to improved and prolonged HRQoL compared with HiDEX in patients with RRMM and end-stage disease. © 2015 Elsevier Inc.

The combination of fluticasone propionate (FLP) and salmeterol (SAL) is often used in clinical practice for the treatment of pulmonary disorders. The purpose of this study was to explore the pharmacokinetics (PK) of inhaled FLP and SAL, after concomitant administration, in healthy male and female subjects using two dry powder inhalers. Plasma concentration (C)-time (t) data were obtained from a single dose, two-sequence, two-period, crossover (2 x 2) bioequivalence (BE) study. Activated charcoal was co-administered in order to prohibit absorption from the gastrointestinal tract. A number of 60 subjects were recruited, while 57 of them completed the study and were included in the PK analysis. Initially, PK parameters of FLP and SAL were estimated using the classic non-compartmental methods. Subsequently, BE assessment was applied to the estimated PK parameters of the two dry powder inhalers. Special focus was placed on the population PK analysis of the C-t data, which were pooled together. `Treatment' (i.e., test or reference) and `period' of the BE study were considered as covariates. A variety of structural and residual error models were tested to find the one which best described the plasma C-t data of FLP and SAL. Demographic data were also evaluated for their impact on the PK parameters. Several goodness-of-fit criteria were utilized. The non-compartmental PK estimates of this study were in agreement with previously reported values. The population PK analysis showed that FLP data were described by a two compartment model with first-order absorption and elimination kinetics. Body weight was found to affect significantly absorption rate constant, inter-compartmental clearance, and volume of distribution of the peripheral compartment. As body weight increases, the values of these PK parameters also rise. For SAL, the best results were obtained when a two-compartment disposition model was used assuming very rapid absorption kinetics (like intravenous bolus) and first-order elimination kinetics. Gender was found to be a significant covariate on clearance, with men exhibiting higher clearance than women. (C) 2015 Elsevier B.V. All rights reserved.

Ketamine is an anesthetic with antidepressant properties. The rapid and lasting effect of ketamine observed in preclinical and clinical research makes it a promising therapeutic to improve current major depression (MD) treatment. Our work intended to evaluate whether the combined use of classic antidepressants (imipramine or fluoxetine) and ketamine would improve the antidepressant response. Using an animal model of depressive-like behavior, we show that the addition of ketamine to antidepressants anticipates the behavioral response and accelerates the neuroplastic events when compared with the use of antidepressants alone. In conclusion, our results suggest the need for a reappraisal of the current pharmacological treatment of MD.

Intercostal hernias are rare, and usually occur following injuries of the thoracic wall. The scope of this report is to present a case of a 53-year-old obese patient that developed a transdiaphragmatic intercostal hernia. The patient presented with a palpable, sizeable, reducible mass in the right lateral thoracic wall, with evident bowel sounds in the area, 6 months after a motor-vehicle accident. On computed tomography (CT), the hernia sac contained part of the liver and part of the ascending colon. A surgical repair of the defect was performed, using a prosthetic patch. The patient's postoperative course was uneventful and she remains recurrence free at 12 months after surgery. Intercostal hernias should be suspected following high-impact injuries of the thoracic wall, and CT scans will facilitate the diagnosis of intercostal hernia. We consider the surgical repair of the defect, with placement of a prosthetic mesh, as the treatment of choice to ensure a favorable outcome.

A study on living coccolithophores from the euphotic zone is conducted in the northeastern Aegean Sea, anarea under the direct influence of the Black Sea waters inflowing into the Aegean. A total of 53 planktonsamples from 5 stations have been collected during four sampling periods between 2011 and 2014. Highconcentrations of Emiliania huxleyi and low concentrations of oligotrophic species, such asholococcolithophores, are indicative of a direct influence of the Black Sea waters inflow on the coccolithophoreassemblages in the northeastern Aegean Sea.

Morbidity and mortality attributable to chronic hepatitis C virus (HCV) infection are increasing in many countries as the infected population ages. Models were developed for 15 countries to quantify and characterize the viremic population, as well as estimate the number of new infections and HCV related deaths from 2013 to 2030. Expert consensus was used to determine current treatment levels and outcomes in each country. In most countries, viremic prevalence has already peaked. In every country studied, prevalence begins to decline before 2030, when current treatment levels were held constant. In contrast, cases of advanced liver disease and liver related deaths will continue to increase through 2030 in most countries. The current treatment paradigm is inadequate if large reductions in HCV related morbidity and mortality are to be achieved.

OBJECTIVES: The objective of this study was to define the natural genotypic variation of the HIV-1 integrase gene across Europe for epidemiological surveillance of integrase strand-transfer inhibitor (InSTI) resistance. METHODS: This was a multicentre, cross-sectional study within the European SPREAD HIV resistance surveillance programme. A representative set of 300 samples was selected from 1950 naive HIV-positive subjects newly diagnosed in 2006-07. The prevalence of InSTI resistance was evaluated using quality-controlled baseline population sequencing of integrase. Signature raltegravir, elvitegravir and dolutegravir resistance mutations were defined according to the IAS-USA 2014 list. In addition, all integrase substitutions relative to HXB2 were identified, including those with a Stanford HIVdb score ≥ 10 to at least one InSTI. To rule out circulation of minority InSTI-resistant HIV, 65 samples were selected for 454 integrase sequencing. RESULTS: For the population sequencing analysis, 278 samples were retrieved and successfully analysed. No signature resistance mutations to any of the InSTIs were detected. Eleven (4%) subjects had mutations at resistance-associated positions with an HIVdb score ≥ 10. Of the 56 samples successfully analysed with 454 sequencing, no InSTI signature mutations were detected, whereas integrase substitutions with an HIVdb score ≥ 10 were found in 8 (14.3%) individuals. CONCLUSIONS: No signature InSTI-resistant variants were circulating in Europe before the introduction of InSTIs. However, polymorphisms contributing to InSTI resistance were not rare. As InSTI use becomes more widespread, continuous surveillance of primary InSTI resistance is warranted. These data will be key to modelling the kinetics of InSTI resistance transmission in Europe in the coming years.

Prions induce lethal neurodegeneration and consist of PrPSc, an aggregated conformer of the cellular prion protein PrPC. Antibody-derived ligands to the globular domain of PrPC (collectively termed GDL) are also neurotoxic. Here we show that GDL and prion infections activate the same pathways. Firstly, both GDL and prion infection of cerebellar organotypic cultured slices (COCS) induced the production of reactive oxygen species (ROS). Accordingly, ROS scavenging, which counteracts GDL toxicity in vitro and in vivo, prolonged the lifespan of prion-infected mice and protected prion-infected COCS from neurodegeneration. Instead, neither glutamate receptor antagonists nor inhibitors of endoplasmic reticulum calcium channels abolished neurotoxicity in either model. Secondly, antibodies against the flexible tail (FT) of PrPC reduced neurotoxicity in both GDL-exposed and prion-infected COCS, suggesting that the FT executes toxicity in both paradigms. Thirdly, the PERK pathway of the unfolded protein response was activated in both models. Finally, 80% of transcriptionally downregulated genes overlapped between prion-infected and GDL-treated COCS. We conclude that GDL mimic the interaction of PrPSc with PrPC, thereby triggering the downstream events characteristic of prion infection.

The performance analysis of the classical M / G / 1 queue, under a general mixed joining/balking strategy was carried out recently by Kerner (Stoch Mod 24:364–375, 2008), who used an analytic approach based on the supplementary variable method. The tractability of the corresponding queueing system with state-dependent arrival rates is particularly significant, as it has important applications in situations where the customers are strategic. In this paper, we present an alternative path for the analysis of the same system, using purely probabilistic arguments.

The novel platinum (II) dimethyl complexes Pt(κ2-L1)Me2 and Pt(κ2-L1)Me2 (1), Pt(κ2-L2a)Me2 (2a) and Pt(κ2-L2b)Me2 (2b) bearing the functionalised N-heterocyclic carbenes (NHCs), L1 = 1-(2-diphenylphosphinoethyl)-3-(2,6-diisopropyl-phenyl)-imidazol-2-ylidene, L2a = 1-(2-pyridyl)-3-(2,6-diisopropyl-phenyl)-imidazol-2-ylidene, L2b = 1-(2-(3-picolinyl))-3-(2, 6-diisopropyl-phenyl)-imidazol-2-ylidene, react with the acid [H(Et2O)2+B(ArF)4-], ArF = 3, 5-(CF3)2C6H3, in the presence of various neutral donors (Dn) to give the salts [{Pt(κ2-L)(Me)(Dn)}+{B(ArF)4}-], where Dn occupies specifically the site trans to the P and the CNHC donor atoms of the coordinated ligands L1 and L2a, L2b, respectively. Spectroscopic data give evidence that the same selectivity prevails when other acids are employed. Activation of the Cl-CH2Cl bond by 2b led to [Pt(κ2-L2b)(Me)Cl], while reaction of CH3I with the dimethyl complexes led to isolable [Pt(κ2-L)Me3I] species.

This paper examines the effects of quantitative easing (QE) announcements by the European Central Bank, the Bank of Japan and the Bank of England on exchange rate dynamics. Using intraday data of three major exchange rates (EUR/USD, GBP/USD, JPY/USD), we apply a univariate APARCH(1,1) model and include QE dummies to empirically investigate how exchange rates are affected in mean and volatility. The empirical results indicate: (i) a direct negative impact on GBP and JPY and no effect of their volatility around the QE announcements of the corresponding central banks, (ii) a delayed devaluation of EUR and an increase of its volatility before and after the ECB’s announcements. Furthermore, the behavior of dynamic conditional correlation among currencies is investigated across the QE announcements. We find a decline in the conditional correlation between EUR and GBP around the announcements by the BoE. These findings highlight the differences on the credibility and effectiveness of the monetary easing strategies and provide important implications from the investors’ and policy makers’ perspective.

We introduce a new method to localize lightwaves. We show how the interaction of a gain medium with a planar deep-UV plasmonic heterostructure, at its zero-vg point, strongly localizes light. A quantum-coherent drive provides a means to control the localization and dramatically improve the dynamics. © OSA 2015.

We analyzed near-infrared data of the nearby galaxy IC5063 taken with the Very Large Telescope SINFONI instrument. IC5063 is an elliptical galaxy that has a radio jet nearly aligned with the major axis of a gas disk in its center. The data reveal multiple signatures of molecular and atomic gas that has been kinematically distorted by the passage of the jet plasma or cocoon within an area of ∼1 kpc2. Concrete evidence that the interaction of the jet with the gas causes the gas to accelerate comes from the detection of outflows in four different regions along the jet trail: near the two radio lobes, between the radio emission tip and the optical narrow-line-region cone, and at a region with diffuse 17.8 GHz emission midway between the nucleus and the north radio lobe. The outflow in the latter region is biconical, centered 240 pc away from the nucleus, and oriented perpendicularly to the jet trail. The diffuse emission that is observed as a result of the gas entrainment or scattering unfolds around the trail and away from the nucleus with increasing velocity. It overall extends for ≳700 pc parallel and perpendicular to the trail. Near the outflow starting points, the gas has a velocity excess of 600-1200 km s-1 with respect to ordered motions, as seen in [Fe ii], {Pa}α , or {{{H}}}2 lines. High {{{H}}}2 (1-0) S(3)/S(1) flux ratios indicate non-thermal excitation of gas in the diffuse outflow.

BACKGROUND: Liver resection is currently the most efficient curative approach for a wide variety of liver tumors. The application of modern techniques and new surgical devices has improved operative outcomes. Radiofrequency ablation is used more often for liver parenchymal transection. This study aimed to assess the efficacy and safety of radiofrequency ablation-assisted liver resection. METHODS: A retrospective study of 145 consecutive patients who underwent radiofrequency ablation-assisted liver resection was performed. Intraoperative blood loss, need for transfusion or intraoperative Pringle maneuver, the duration of liver parenchymal transection, perioperative complications, and postoperative morbidity and mortality were all evaluated. RESULTS: Fifty minor and ninety-five major liver resections were performed. The mean intraoperative blood loss was 251 mL, with a transfusion rate of 11.7%. The Pringle maneuver was necessary in 12 patients (8.3%). The mean duration for parenchymal transection was 51.75 minutes. There were 47 patients (32.4%) with postoperative complications. There is no mortality within 30 days after surgery. CONCLUSIONS: Radiofrequency ablation-assisted liver resection permits both major and minor liver resections with minimal blood loss and without occlusion of hepatic inflow. Furthermore it decreases the need for blood transfusion and reduces morbidity and mortality. (

Since 2011, Romania has faced an HIV outbreak among injecting drug users (IDUs). Our aim was to identify and describe clinical and epidemiological patterns of this outbreak. A cross-sectional study enrolled 138 IDUs diagnosed with HIV infection between 2011 and 2013 with 58 sexually infected individuals included as the control group. The IDUs had a long history of heroin abuse (10 years) and a recent history of new psychostimulant injection (3-4 years). Classical epidemiological data and molecular techniques were used to describe the transmission dynamics. A high prevalence of hepatitis C virus (HCV) coinfection was noted (98.6%) compared to the control group (10.3%) (p<0.001). IDUs had initially been infected with HCV. HIV infection was more recent, linked to starting injecting stimulants. HIV subtype analysis showed a predominance of the local F1 strain in both IDUs and sexually infected patients; in IDUs it also identified 28 CRF14_BG recombinants and six unique recombinant forms (URFs) between F1 and CRF14_BG. A few patients from both risk groups were infected with subtype B. Among IDUs, CRF14_BG was associated with a lower CD4 cell count and more advanced stages of disease, which correlated with CXCR4 tropism. Phylogenetic analysis revealed the spread of HIV through three major IDU clusters of recent date. Among IDUs with CRF14_BG, some reported travel abroad (Spain, Greece). By identifying clusters of IDUs with related viruses, molecular epidemiologic methods provide valuable information on patterns of HIV transmission that can be useful in planning appropriate harm reduction interventions.

We report the detection of three new X-ray transients and one recurrent X-ray source in recent XMM-Newton observations of the M31 disk. Two 100-ks observations were carried out on 2015-06-28 (ObsID 0763120101; June) and 2015-08-11 (ObsID 0763120301; August).

The aim of this study is to analyze and quantify the future projections of heat waves in Greece. For this reason, specific climatic indices were used in the analysis concerning absolute, percentile and duration indices defined by the CCl/CLIVAR/JCOMM Expert Team (ET) on Climate Change Detection and Indices (ETCCDI). The future projections (SRES A1B) of these indices such as summer days, tropical days, maximum daily maximum air temperature, warm days, tropical nights, maximum daily minimum air temperature, warm nights and warm spell duration were carried out using six regional climate models from the ENSEMBLES project, concerning the near future 2031-2050 and the far future 2071-2100 compared to the reference period 1961-1990. The ensemble means along with the inter-model-standard deviations of the examined extreme indices for the future model projections are presented and analyzed. Further, the findings of this analysis are discussed against recent recorded heat waves during 2007, in order to understand if such events are even more extreme or common in the future climate. It is very likely, that the anomalies observed in 2007, especially for extreme indices of minimum air temperature, could be more frequent considered as typical events by the end of the 21th century. © 2014 Elsevier B.V.

The cytokine granulocyte colony-stimulating factor (G-CSF) binds to its receptor (G-CSFR) to stimulate hematopoietic stem cell mobilization, myelopoiesis, and the production and activation of neutrophils. In response to exercise-induced muscle damage, G-CSF is increased in circulation and G-CSFR has recently been identified in skeletal muscle cells. While G-CSF/G-CSFR activation mediates pro- and anti-inflammatory responses, our understanding of the role and regulation in the muscle is limited. The aim of this study was to investigate, in vitro and in vivo, the role and regulation of G-CSF and G-CSFR in skeletal muscle under conditions of muscle inflammation and damage. First, C2C12 myotubes were treated with lipopolysaccharide (LPS) with and without G-CSF to determine if G-CSF modulates the inflammatory response. Second, the regulation of G-CSF and its receptor was measured following eccentric exercise-induced muscle damage and the expression levels we investigated for redox sensitivity by administering the antioxidant N-acetylcysteine (NAC). LPS stimulation of C2C12 myotubes resulted in increases in G-CSF, interleukin (IL)-6, monocyte chemoattractant protein-1 (MCP-1), and tumor necrosis factor-α (TNFα) messenger RNA (mRNA) and an increase in G-CSF, IL-6, and MCP-1 release from C2C12 myotubes. The addition of G-CSF following LPS stimulation of C2C12 myotubes increased IL-6 mRNA and cytokine release into the media, however it did not affect MCP-1 or TNFα. Following eccentric exercise-induced muscle damage in humans, G-CSF levels were either marginally increased in circulation or remain unaltered in skeletal muscle. Similarly, G-CSFR levels remained unchanged in response to damaging exercise and G-CSF/G-CSFR did not change in response to NAC. Collectively, these findings suggest that G-CSF may cooperate with IL-6 and potentially promote muscle regeneration in vitro, whereas in vivo aseptic inflammation induced by exercise did not change G-CSF and G-CSFR responses. These observations suggest that different models of inflammation produce a different G-CSF response.

Self-determination theory posits that satisfaction of the needs for autonomy, competence and relatedness represents the basic nutriments for humans’ optimal functioning. It also postulates that with greater the degree to which these three needs are equally satisfied, the quality of motivation is further enhanced. Yet, this premise has remained relatively underexplored. In this correlational study, we surveyed Greek middle-school students (N = 435; 47.1% males; Mage = 13.95; SD = 0.85) and investigated to what extent balanced need satisfaction contributes over and above the need satisfaction in the prediction of quality of motivation in physical education contexts. Path analysis showed that need satisfaction along with balanced need satisfaction were linked with autonomous motivation but not with controlled motivation. The present findings imply that balanced satisfaction of the needs for autonomy, competence and relatedness can be an additional source of optimal motivation and functioning in physical education.

Observations of gamma-ray-bursts and jets from active galactic nuclei reveal that the jet flow is characterized by a high radiative efficiency and that the dissipative mechanism must be a powerful accelerator of non-thermal particles. Shocks and magnetic reconnection have long been considered as possible candidates for powering the jet emission. Recent progress via fully-kinetic particle-in-cell simulations allows us to revisit this issue on firm physical grounds. We show that shock models are unlikely to account for the jet emission. In fact, when shocks are efficient at dissipating energy, they typically do not accelerate particles far beyond the thermal energy, and vice versa. In contrast, we show that magnetic reconnection can deposit more than 50 per cent of the dissipated energy into non-thermal leptons as long as the energy density of the magnetic field in the bulk flow is larger than the rest-mass energy density. The emitting region, i.e. the reconnection downstream, is characterized by a rough energy equipartition between magnetic fields and radiating particles, which naturally accounts for a commonly observed property of blazar jets.

In this article the author argues that the teaching of religion(s) in education, in a social pedagogical context, can encourage community cohesion especially when, during the current harsh crisis, the need for cohesion seems to be of paramount importance in enabling seemingly insurmountable problems to be overcome. At the same time minorities become vulnerable and diversity, a matter of high priority, comes to the fore. The author reviews evidence of research on the effect of educational intervention within Religious Education on student attitudes toward religious diversity. He proposes that constructivist methodology, using theatre/drama as a means of Religious Education, could give people the choice to be critical religious believers and active members in a society applyingthe fundamental social pedagogical principle of tolerance to and respect for the ‘other’.

Religious Education (RE) in Greece is a compulsory school subject according the 2011 new framework for compulsory education, entitled ‘New School’. This article focuses on two statutory documents for RE, ‘The Curriculum for RE’ and the ‘The Teacher’s Guide for RE’, and the pilot scheme of the new curriculum running in school years, 2011–2014, in 188 schools (primary and secondary education). Findings of the research demonstrate that, though the revision seems inevitable, the pedagogical and theological dimension of the RE curriculum is radical as it is based on contemporary theories and methodologies of the construction of the curriculum and RE approaches. However, the article indicates constructivist and critical approaches to RE that influenced the change to an actual non-confessional compulsory subject and also highlighted the tension between an overall constructivist approach to learning and the traditional orthodox content of much of the curriculum. The author opens a discussion on problematic aspects that need to be taken in to consideration when revising the curriculum.

This study is an attempt to address the issue of religion in the public sphere and secularism. Since the Eastern Orthodox Church has been established by the Greek constitution (1975) as the prevailing religion of Greece, there are elements of legal agreements-which inevitably spawn interactions-between state and Church in different areas. One such area is Religious Education. This article focuses on Religious Education (RE) in Greece which is a compulsory school subject and on two important interventions that highlight the interplay between religion, politics and education: firstly the new Curriculum for RE (2011) and secondly the introduction of an Islamic RE (2014) in a Greek region (Thrace) where Christians and Muslims have lived together for more than four centuries. The researches are based on fieldwork research and they attempt to open the discussion on the role of RE in a secular education system and its potential for coexistence and social cohesion.

Purpose: The clinical outcome of multiple myeloma (MM) is heterogeneous. A simple and reliable tool is needed to stratify patients with MM. We combined the International Staging System (ISS) with chromosomal abnormalities (CA) detected by interphase fluorescent in situ hybridization after CD138 plasma cell purification and serum lactate dehydrogenase (LDH) to evaluate their prognostic value in newly diagnosed MM (NDMM). Patients and Methods: Clinical and laboratory data from 4,445 patients with NDMM enrolled onto 11 international trials were pooled together. The K-adaptive partitioning algorithm was used to define the most appropriate subgroups with homogeneous survival. Results: ISS, CA, and LDH data were simultaneously available in 3,060 of 4,445 patients. We defined the following three groups: revised ISS (R-ISS) I (n = 871), including ISS stage I (serum β2-microglobulin level < 3.5 mg/L and serum albumin level ≥ 3.5 g/dL), no high-risk CA [del(17p) and/or t(4;14) and/or t(14;16)], and normal LDH level (less than the upper limit of normal range); R-ISS III (n = 295), including ISS stage III (serum β2-microglobulin level > 5.5 mg/L) and high-risk CA or high LDH level; and R-ISS II (n = 1,894), including all the other possible combinations. At a median follow-up of 46 months, the 5-year OS rate was 82% in the R-ISS I, 62% in the R-ISS II, and 40% in the R-ISS III groups; the 5-year PFS rates were 55%, 36%, and 24%, respectively. Conclusion: The R-ISS is a simple and powerful prognostic staging system, and we recommend its use in future clinical studies to stratify patients with NDMM effectively with respect to the relative risk to their survival. © 2015 American Society of Clinical Oncology.

The epidemiology of multiple myeloma (MM) is an increasingly investigated field, with many controversies. This systematic review aims to synthesize meta-analyses examining risk factors for MM so as to provide a comprehensive, parsimonious summary of the current evidence. Eligible meta-analyses were sought in PubMed adopting a predefined algorithm, without any restriction of publication language; end-of-search date was October 10, 2014. The selection of eligible studies and data extraction were performed by working in pairs, independently and blindly to each other; in case of disagreement, consensus with the whole team was reached. Among the 22 ultimately included meta-analyses, 9 examined occupational factors, 4 assessed aspects of lifestyle (smoking, alcohol, body mass index), 5 evaluated the presence of other diseases, and 4 addressed genetic factors as potential risk factors of MM. A vast compendium of significant associations arose, including farming, occupation as a firefighter, occupation as a hairdresser, exposures to chemicals or pesticides, overweight and obesity, patterns of alcohol intake, pernicious anemia, ankylosing spondylitis, gene promoter methylation, and polymorphisms. In conclusion, MM is a multifactorial disease, encompassing a wide variety of risk factors that span numerous life aspects. Further accumulation of evidence through meta-analyses is anticipated in this rapidly growing field. © 2015 Elsevier Inc.

Purpose: The aim of International Myeloma Working Group was to develop practical recommendations for the use of magnetic resonance imaging (MRI) in multiple myeloma (MM). Methods: An interdisciplinary panel of clinical experts on MM and myeloma bone disease developed recommendations for the value of MRI based on data published through March 2014. Recommendations: MRI has high sensitivity for the early detection of marrow infiltration by myeloma cells compared with other radiographic methods. Thus, MRI detects bone involvement in patients with myeloma much earlier than the myeloma-related bone destruction, with no radiation exposure. It is the gold standard for the imaging of axial skeleton, for the evaluation of painful lesions, and for distinguishing benign versus malignant osteoporotic vertebral fractures. MRI has the ability to detect spinal cord or nerve compression and presence of soft tissue masses, and it is recommended for the workup of solitary bone plasmacytoma. Regarding smoldering or asymptomatic myeloma, all patients should undergo whole-body MRI (WB-MRI; or spine and pelvic MRI if WB-MRI is not available), and if they have > one focal lesion of a diameter > 5 mm, they should be considered to have symptomatic disease that requires therapy. In cases of equivocal small lesions, a second MRI should be performed after 3 to 6 months, and if there is progression on MRI, the patient should be treated as having symptomatic myeloma. MRI at diagnosis of symptomatic patients and after treatment (mainly after autologous stem-cell transplantation) provides prognostic information; however, to date, this does not change treatment selection. © 2015 by American Society of Clinical Oncology.

This work discusses the scientific aspects of the definition of dose as the `highest single oral IR dose' recommended for administration in the SmPC (summary of product characteristics) in the current European Medicines Agency (EMA) 2010 Guideline, for the purpose of biopharmaceutics classification system (BCS)-based biowaiver decision making. Analysis of theoretical and experimental data dealing with drug dissolution and biopharmaceutic drug classification reveals that the drug dose is an important parameter for both drug dissolution and biopharmaceutic classification. The relevant implications for the dose considerations in bioequivalence studies are also discussed briefly. It is suggested that the concept of ``the highest single dose oral IR dose recommended for administration in the SmPC{''} of the EMA 2010 Guideline be abolished. It is advisable, each dose strength be considered separately Le., whether or not it meets the solubility-dissolution regulatory criteria. (C) 2014 Elsevier B.V. All rights reserved.

Because changes in sea level may have a great impact on the distribution of mineral resources, the exploration and exploiting of these resources should not ignore the changes in sea level that may have occurred in the past in the area considered. The study of relative sea-level changes is an essential element of ocean observation and technological advances are often necessary to improve this study that includes the determination of levels (elevation or depth), chronological estimations, and the identification of appropriate sea-level indicators.Indicators of fossil or present-day sea-level positions are the most important elements for a sea-level reconstruction, because they provide information not only on the former level but also on the accuracy of the reconstruction.A classification is proposed of the main criteria that can be used to deduce appropriate sea-level indicators from geomorphological, stratigraphical, biological or archeological coastal data. Two cases studies are used as examples of sea-level reconstructions that may be useful to clarify the geology in certain areas, or to coastal engineering and coastal protection: (1) on the impact of the recent sea-level rise in the interpretation of sea-level indicators; and (2) on the foreseeable impacts of the predicted near-future sea-level rise on the coasts of NE Italy.

Damage scenarios were developed for the Lefkada old town (LOT). LOT is the historical center of the capital of Lefkas Island, part of the Ionian Islands, one of the most seismically prone areas within the Mediterranean region that suffered numerous devastating earthquakes in the past. The most recent strong earthquake with Mw = 6.2 occurred on 14 August 2003 at a distance of about 13 km from LOT. A peak ground acceleration (PGA) equal to 0.42 g was recorded in LOT, one of the highest values ever recorded in Greece. Nevertheless, the 2003 event produced limited damage to the buildings of LOT, comprising traditional construction practices of architectural significance and a high seismic behaviour. Towards the development of damage scenarios the following tasks were performed: (a) buildings inventory and vulnerability indices determination using EMS-98 along with behaviour modification scores, (b) subsoil response functions and 1D visco-elastic models calculation using microtremors and (c) stochastic PGA simulation using site amplification deduced from the subsoil response functions. Two scenarios were developed considering the sources of the 2003 M6.2 earthquake and a future M7 event, located at the same fault. The discrete damage probability was resolved by formulating a beta distribution of an average damage grade related to the vulnerability index and the simulated PGA through empirical equations. The deduced models are comparable with the observed 2003 damage distribution, hence they are likely useful for preparing future emergency plans. In the aftermath, although further investigation is needed to explain outliers, the implementation of the followed methodology into an automated procedure for near real time shake and damage maps generation in case of a seismic crisis is highly recommended. The work herein, with proper adaptations, is potentially fairly applicable for other towns and regions in Europe.

This study focuses on a series of small intraplate earthquakes that took place during May–August 2013 on the southwestern coast of the Corinth Rift (Central Greece), a few km southeast of Aigion city. The Corinth Rift is one of the most seismically active parts of the Mediterranean. We analyzed more than 1500 events with 0.4≤ML≤3.7, the major part of which was recorded by a dense local network. The seismicity is densely clustered in a volume of dimensions ∼4×2×6km3, aligned in a N110° direction and at depths ranging between 6 and 12km. Precisely relocated hypocenters and reliably constrained focal mechanisms indicate north dipping planar faults with an average dip of ∼60°. Stress inversion of focal mechanisms implies that the dominant local stress field is extensional in a N5° direction, in good agreement with geodetic observations. The swarm evolved in two phases, with a spatiotemporal migration of epicenters from the eastern toward the western part of the rupture zone, while slip distribution appears homogeneous over the eastern part and strongly inhomogeneous in the western part. These two phases also produced different results in scaling relations such as the Gutenberg–Richter law, the Modified Omori Formula and the Epidemic Type of Aftershock Sequence model. Similar results from other studies have been reported and correlated with a fluid driven mechanism, however further research is required to strengthen this hypothesis for the purposes of this study.

INTRODUCTION: Morphologic homogeneity is desirable in sample selection of clinical studies that evaluate methods of treating craniofacial discrepancies in orthodontics. The purposes of this study were to assess sample selection criteria commonly used in the orthodontic literature regarding their effectiveness in achieving morphologic homogeneity, and to propose a method that can guarantee selection of a homogeneous sample, for which the degree of homogeneity and the average skeletal pattern can be specified a priori. METHODS: Pretreatment lateral cephalograms from 170 consecutive patients (82 boys, 88 girls) aged 7 to 17 years were used. Sixteen skeletal and 4 dental landmarks were digitized and processed with Procrustes superimposition and principal component analysis. The sample was bootstrapped to a virtual population of 10,000 subjects by random sampling from the normal distribution for each principal component. A systematic literature search of randomized controlled trials showed that the most prevalent sample selection criteria, in addition to molar relationship, included overjet, ANB, and SN-GoGn. Each criterion was applied to the virtual population. The morphologic homogeneity of the samples was assessed as the percentage of shape variance of each sample relative to the shape variance of the population. RESULTS: The first 3 principal components incorporated approximately 53% of shape variability. The evaluated criteria achieved low or moderate morphologic homogeneity scores (range, 28%-63%), and the selected patients were widely spread in the shape space. Although the criteria are commonly applied for selecting samples with skeletal discrepancies, a considerable number of subjects with an average shape were selected. The proposed procedure entails selecting a skeletal pattern appropriate for the study's purpose, setting limits in shape space within which the sample should be confined, and testing candidate patients against these limits. The patients within these boundaries have, by definition, a similar shape to the selected skeletal pattern and form a homogeneous sample. CONCLUSIONS: The cephalometric variables that have been used in randomized controlled trials do not result in samples of high morphologic homogeneity. The proposed method guarantees high morphologic homogeneity. The extent of homogeneity, the average shape of the sample, and the sample's relationship to the general population's average can be specified a priori.

Blazars have been suggested as possible neutrino sources long before the recent IceCube discovery of high-energy neutrinos. We re-examine this possibility within a new framework built upon the blazar simplified view and a self-consistent modelling of neutrino emission from individual sources. The former is a recently proposed paradigm that explains the diverse statistical properties of blazars adopting minimal assumptions on blazars' physical and geometrical properties. This view, tested through detailed Monte Carlo simulations, reproduces the main features of radio, X-ray, and γ-ray blazar surveys and also the extragalactic γ-ray background at energies ≳ 10 GeV. Here, we add a hadronic component for neutrino production and estimate the neutrino emission from BL Lacertae objects as a class, `calibrated' by fitting the spectral energy distributions of a preselected sample of such objects and their (putative) neutrino spectra. Unlike all previous papers on this topic, the neutrino background is then derived by summing up at a given energy the fluxes of each BL Lac in the simulation, all characterized by their own redshift, synchrotron peak energy, γ-ray flux, etc. Our main result is that BL Lacs as a class can explain the neutrino background seen by IceCube above ∼0.5 PeV while they only contribute ∼10 per cent at lower energies, leaving room to some other population(s)/physical mechanism. However, one cannot also exclude the possibility that individual BL Lacs still make a contribution at the ≈20 per cent level to the IceCube low-energy events. Our scenario makes specific predictions, which are testable in the next few years.

Both in vitro and in vivo experiments have confirmed that platelet-rich plasma has therapeutic effects on many neuropathies, but its effects on carpal tunnel syndrome remain poorly understood. We aimed to investigate whether single injection of platelet-rich plasma can improve the clinical symptoms of carpal tunnel syndrome. Fourteen patients presenting with median nerve injury who had suffered from mild carpal tunnel syndrome for over 3 months were included in this study. Under ultrasound guidance, 1-2 mL of platelet-rich plasma was injected into the region around the median nerve at the proximal edge of the carpal tunnel. At 1 month after single injection of platelet-rich plasma, Visual Analogue Scale results showed that pain almost disappeared in eight patients and it was obviously alleviated in three patients. Simultaneously, the disabilities of the arm, shoulder and hand questionnaire showed that upper limb function was obviously improved. In addition, no ultrasonographic manifestation of the carpal tunnel syndrome was found in five patients during ultrasonographic measurement of the width of the median nerve. During 3-month follow-up, the pain was not greatly alleviated in three patients. These findings show very encouraging mid-term outcomes regarding use of platelet-rich plasma for the treatment of carpal tunnel syndrome.

Purpose: Clozapine is an atypical neuroleptic agent, effective in treating drug-resistant schizophrenia. The aim of this work was to investigate overall sleep architecture and sleep spindle morphology characteristics, before and after combination treatment with clozapine, in patients with drug-resistant schizophrenia who underwent polysomnography. Methods: Standard polysomnographic techniques were used. To quantify the sleep spindle morphology, a modeling technique was used that quantifies time-varying patterns in both the spindle envelope and the intraspindle frequency. Results: After combination treatment with clozapine, the patients showed clinical improvement. In addition, their overall sleep architecture and, more importantly, parameters that quantify the time-varying sleep spindle morphology were affected. Specifically, the results showed increased stage 2 sleep, reduced slow-wave sleep, increased rapid eye movement sleep, increased total sleep time, decreased wake time after sleep onset, as well as effects on spindle amplitude and intraspindle frequency parameters. However, the above changes in overall sleep architecture were statistically nonsignificant trends. Conclusions: The findings concerning statistically significant effects on spindle amplitude and intraspindle frequency parameters may imply changes in cortical sleep EEG generation mechanisms, as well as changes in thalamic pacing mechanisms or in thalamo-cortical network dynamics involved in sleep EEG generation, as a result of combination treatment with clozapine. Significance: Sleep spindle parameters may serve as metrics for the eventual development of effective EEG biomarkers to investigate treatment effects and pathophysiological mechanisms in schizophrenia.

An empirical study was conducted to evaluate the users' perception on a pilot mobile application ("SMART Travel Health"), their attitude towards use, and their intention to use it. A theoretical model was constructed based on TAM and other related works. The population was 88 travellers who used the pilot application. Data analysis was performed using partial least squares path modeling. Results highlight the very strong significant effect of perceived ease of use to perceived usefulness, the strong significant effect of perceived usefulness to attitude towards use, as well as, the significant effect of perceived ease of use to attitude towards using the application. Also, the strong significant effect of attitude towards use to behavioral intention to use is presenting the positive perception of the population about this mobile application.

If solitude, as a state of being alone, is a basic human need equally important to attachment and belonging, it is necessary to explore its multiple positive contributions to children's and adolescents' development. However, this type of solitude is a relatively neglected research area in these age periods. Research evidence on the existence, significance, and developmental course of positive aloneness experiences is the focus of this chapter beginning with some clarifications on the various concepts of aloneness (i.e., loneliness, aloneness, solitude, attitude toward aloneness, privacy). Next, research is reviewed on assessment of aloneness and solitude; understanding and content of solitude; assessment of aloneness and solitude; amount, context, and affect of time alone; attitude toward aloneness; the links between solitude and adjustment; the associations between solitude and strategies of coping with loneliness; and the associations between solitude and other aloneness concepts. Data on gender differences also are discussed. Finally, suggestions are offered fo rfuture research on this type of solitude in childhood and adolescence.

The paper describes a framework for the education of ESOL teachers that is inspired by principles grounded in research on English as a lingua franca (ELF) and world Englishes (WE). The essential feature of such a framework is that it involves interested teachers in a critical reorientation of their beliefs toward English language teaching, learning and communication. This transformative framework informs what we call the ‘ELF-aware’ teacher education component. We then present a framework for a transformative perspective for ELF-aware and WE-aware teachers and describe the phases of a teacher education project that attempted to put this framework into practice.

Recent work in the field of English as a Lingua Franca (henceforth ELF) has been focused on defining, delineating, and clarifying the nature of ELF. While some work has addressed issues of teacher education and training (see below for a review), we have yet to see a comprehensive proposal that aims both to educate English as a Foreign Language (henceforth EFL) or English as a Second Language (henceforth ESL) teachers about ELF and to engage them in developing, teaching, and evaluating ELF-aware lessons in their own teaching context.

Ο Διονύσιος και ο αδερφός του Ανδρέας Δεβάρης υπήρξαν σημαντικές προσωπικότητες των αρχών του 20ού αι. Ο Ανδρέας έδρασε ως ηθοποιός, ζωγράφος, μυθιστοριογράφος αλλά και αθλητής ενώ ο Διονύσιος, εκτός από ηθοποιός ήταν θεατρικός συγγραφέας, σκηνοθέτης και δημοσιογράφος. Ο Διονύσιος Δεβάρης, δραστηριοποιήθηκε συστηματικότερα στη θεατρική τέχνη: στις αρχές του 20ού αι. πρωτοεμφανίστηκε ως «μύστης» της «Νέας Σκηνής» του Κ. Χρηστομάνου, το 1909 βρέθηκε στο Παρίσι ενταγμένος στο θίασο του Raymond Duncan ερμηνεύοντας τον Ορέστη στην «Ηλέκτρα» του Σοφοκλή και την επόμενη χρονιά με τον ίδιο θίασο περίοδευσε στις Η.Π.Α., όπου και παρέμεινε για να σπουδάσει αγγλική φιλολογία. Πρωτοστάτησε στις διαδηλώσεις κατά της «Ηλέκτρας» του Hofmannsthal, η οποία παιζόταν το 1910 στη Νέα Υόρκη, θεωρώντας ότι βεβηλωνόταν το αρχαίο ελληνικό θέατρο. Επιστρέφοντας στην Ελλάδα εργάστηκε ως αρχισυντάκτης αθηναϊκών εφημερίδων και παράλληλα άρχισε να συγγράφει θεατρικά έργα. Στις αρχές της δεκαετίας του 1930 συνεργάστηκε με το Σωκράτη Καραντινό και το 1934 ίδρυσε με τον Κάρολο Κουν και το Γιάννη Τσαρούχη τη «Λαϊκή Σκηνή». Υπήρξε ένθερμος υποστηρικτής των Duncan, των Σικελιανών και της Δελφικής Ιδέας, ενώ παράλληλα μέσα από την αρθρογραφία του συχνά διατύπωνε θέσεις και κρίσεις για την αναβίωση του αρχαίου δράματος.

This work presents the current state of seismic vulnerability in Greece, the most seismically active region in Europe and the corresponding impacts of austerity measures imposed to the nation during the last five years. The analysis of physical risks and socio-economic conditions shows a very dangerous situation, which has to be promptly confronted, in terms of a revised and prioritized National reinforcement effort regarding pre-seismic preparedness and post-seismic interventions. The latter certainly requires funding, however it has to be coupled with restorative measures for the existing socio-political status embracing authorities, communities and individuals.

In this paper we attempt to map erosion and deposition zones in the island of Samos (Greece). The relief of Samos is characterized by hilly and mountainous geomorphology mantled by surface sediments and soils. The processes of erosion depends mainly on the frequency and magnitude of precipitation, surface water flow, slope characteristics, rock’s susceptibilitiy to erosion, vegetation and human impacts. The aim of this paper is to study these dynamic processes using easily updated spatial mapping processes in order to design structures to minimize erosion.

The inverse Compton catastrophe is defined as a dramatic rise in the luminosity of inverse Compton scattered photons. It is described by a non-linear loop of radiative processes that sets in for high values of the electron compactness and is responsible for the efficient transfer of energy from electrons to photons, predominantly through inverse Compton scatterings. We search for the conditions that drive a magnetized non-thermal source to the inverse Compton catastrophe regime and study its multiwavelength (MW) photon spectrum. We develop a generic analytical framework and use numerical calculations as a backup to the analytical predictions. We find that the escaping radiation from a source in the Compton catastrophe regime bears some unique features. The MW photon spectrum is a broken power law with a break at ∼mec2 due to the onset of the Klein-Nishina suppression. The spectral index below the break energy depends on the electron and magnetic compactnesses logarithmically, while it is independent of the electron power-law index (s). The maximum radiating power emerges typically in the γ-ray regime, at energies ∼mec2 (∼γmax mec2) for s > 2 (s ≲ 2), where γmax is the maximum Lorentz factor of the injected electron distribution. We apply the principles of the inverse Compton catastrophe to blazars and γ-ray bursts using the analytical framework we developed, and show how these can be used to impose robust constraints on the source parameters.

The inverse Compton catastrophe is defined as a dramatic rise in the luminosity of inverse Compton scattered photons. It is described by a non-linear loop of radiative processes that sets in for high values of the electron compactness and is responsible for the efficient transfer of energy from electrons to photons, predominantly through inverse Compton scatterings. We search for the conditions that drive a magnetized non-thermal source to the inverse Compton catastrophe regime and study its multiwavelength (MW) photon spectrum. We develop a generic analytical framework and use numerical calculations as a backup to the analytical predictions. We find that the escaping radiation from a source in the Compton catastrophe regime bears some unique features. The MW photon spectrum is a broken power law with a break at ∼mec2 due to the onset of the Klein-Nishina suppression. The spectral index below the break energy depends on the electron and magnetic compactnesses logarithmically, while it is independent of the electron power-law index (s). The maximum radiating power emerges typically in the γ-ray regime, at energies ∼mec2 (∼γmax mec2) for s > 2 (s ≲ 2), where γmax is the maximum Lorentz factor of the injected electron distribution. We apply the principles of the inverse Compton catastrophe to blazars and γ-ray bursts using the analytical framework we developed, and show how these can be used to impose robust constraints on the source parameters.

An important contribution to the thermoelectric and spin-caloric transport properties in magnetic materials at elevated temperatures is the formation of a spin-disordered state due to local moment fluctuations. This effect has not been largely investigated so far. We focus on various magnetic nanostructures of CrTe in the form of thin layers or nanowires embedded in ZnTe matrix, motivated by the miniaturization of spintronics devices and by recent suggestions that magnetic nanostructures can lead to extraordinary thermoelectric effects due to quantum confinement. The electronic structure of the studied systems is calculated within the multiple scattering screened Korringa-Kohn-Rostoker Green function (KKR-GF) framework. The Monte Carlo method is used to simulate the magnetization in the temperature induced spin disorder. The transport properties are evaluated from the transmission probability obtained using the Baranger-Stone approach within the KKR-GF framework. We find qualitative and quantitative changes in the thermoelectric and spin-caloric coefficients when spin disorder is included in the calculation. Furthermore, we show that substitutional impurities in CrTe nanowires could considerably enhance the Seebeck coefficient and the thermoelectric figure of merit.

We present the statistics of the ratio, R, between the prompt and afterglow “plateau” fluxes of gamma-ray bursts (GRBs). We define this as the ratio of the mean prompt energy flux in Swift BAT and the Swift XRT one, immediately following the steep transition between these two states and the beginning of the afterglow stage referred to as the “plateau”. Like the distribution of many other GRB observables, the histogram of R is log-normal with maximum at a value {{R}m}≃ 2000, FWHM of about two decades, and with the entire distribution spanning about five decades in the value of R. We note that the peak of the distribution is close to the proton-to-electron mass ratio ({{R}m}≃ {{m}p}/{{m}e}=1836), as proposed to be the case in an earlier publication, on the basis of a specific model of the GRB dissipation process. It therefore appears that, in addition to the values of the energy of peak luminosity {{E}pk}∼ {{m}e}{{c}2}, GRBs present us with one more quantity with an apparent characteristic value. The fact that the values of both these quantities ({{E}pk} and R) are consistent with the same specific model invoked to account for the efficient conversion of their relativistic proton energies to electrons argues favorably for its underlying assumptions.

The photoluminescence properties of CuInS2/ZnS quantum dots (QDs) dispersed in solutions of different concentrations and solvent polarity and deposited as solid films on quartz substrates by drop-casting and spin-coating are studied. Both steady state and time-resolved photoluminescence spectroscopy have been used. The CuInS2/ZnS QDs in solutions exhibit a red-shift of their absorption and photoluminescence spectra by increasing concentration and solvent polarity. In addition, they exhibit a three-exponential decay with time constants 1-3, 20-40 and 200-300 ns, depending on solvent, concentration and detection wavelength. In films, a red-shifted photoluminescence spectrum is observed for films made by drop-casting compared to those prepared by spin-coating. The time-resolved photoluminescence decays in films, apart from the three mechanisms observed in solutions, also exhibit a fast decay component of <1 ns, which is more pronounced in the spin coated films and especially at long emission wavelengths. The time resolved photoluminescence spectra in the drop-casted films experience a larger transient red-shift than in the spin-coated ones, indicative of a possible energy transfer among adjacent QDs. In general, it is shown that the chemical environment and the presence of defects play a central role in the recombination processes. © 2015 Elsevier B.V. All rights reserved.

The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 15 countries, and the relative impact of two scenarios was considered: (i) increased treatment efficacy while holding the treated population constant and (ii) increased treatment efficacy and increased annual treated population. Increasing levels of diagnosis and treatment, in combination with improved treatment efficacy, were critical for achieving substantial reductions in disease burden. In most countries, the annual treated population had to increase several fold to achieve the largest reductions in HCV-related morbidity and mortality. This suggests that increased capacity for screening and treatment will be critical in many countries. Birth cohort screening is a helpful tool for maximizing resources. In most of the studied countries, the majority of patients were born between 1945 and 1985.

Stress exposure triggers cognitive and behavioral impairments that influence decision-making processes. Decisions under a context of uncertainty require complex reward-prediction processes that are known to be mediated by the mesocorticolimbic dopamine (DA) system in brain areas sensitive to the deleterious effects of chronic stress, in particular the orbitofrontal cortex (OFC). Using a decision-making task, we show that chronic stress biases risk-based decision-making to safer behaviors. This decision-making pattern is associated with an increased activation of the lateral part of the OFC and with morphological changes in pyramidal neurons specifically recruited by this task. Additionally, stress exposure induces a hypodopaminergic status accompanied by increased mRNA levels of the dopamine receptor type 2 (Drd2) in the OFC; importantly, treatment with a D2/D3 agonist quinpirole reverts the shift to safer behaviors induced by stress on risky decision-making. These results suggest that the brain mechanisms related to risk-based decision-making are altered after chronic stress, but can be modulated by manipulation of dopaminergic transmission.

Composite magnetoplasmonic nanoparticles with a core-shell morphology exhibit intriguing optical properties and offer impressive opportunities for tailoring in a controllable manner the light-matter interaction at subwavelength dimensions. These properties are usually analyzed in the framework of the quasi-static approximation, which, however, is often inadequate; thus, a full electrodynamic treatment is required. In this respect, we developed a rigorous method for an accurate description of electromagnetic scattering by a gyrotropic sphere coated with a nongyrotropic concentric spherical shell, based on the full multipole expansion of the wave field. The method was applied to specific examples of core-shell cobalt-silver spherical nanoparticles, where the occurrence of strong circular dichroism induced by magnetoplasmonic interaction, which largely exceeds that of homogeneous noble metal nanoparticles in an external magnetic field, was found. Our results were also explained by reference to the quasi-static approximation, which, though it reproduces the main features of the absorption spectra, strongly overestimates circular dichroism in the cases we studied.

Amyloid deposits to the islets of Langerhans are responsible for the gradual loss of pancreatic β-cells leading to type II diabetes mellitus. Human mature islet amyloid polypeptide (hIAPP), a 37-residue pancreatic hormone, has been identified as the primary component of amyloid fibrils forming these deposits. Several individual segments along the entire sequence length of hIAPP have been nominated as regions with increased amyloidogenic potential, such as regions 8–20, 20–29, and 30–37. A smaller fragment of the 8–20 region, spanning residues 8–16 of hIAPP has been associated with the formation of early transient α-helical dimers that promote fibrillogenesis and also as a core part of hIAPP amyloid fibrils. Utilizing our aggregation propensity prediction tools AmylPred and AmylPred2, we have identified the high aggregation propensity of the 8–16 segment of hIAPP. A peptide analog corresponding to this segment was chemically synthesized and its amyloidogenic properties were validated using electron microscopy, X-ray fiber diffraction, ATR FT-IR spectroscopy, and polarized microscopy. Additionally, two peptides introducing point mutations L12R and L12P, respectively, to the 8–16 segment, were chemically synthesized. Both mutations disrupt the α-helical properties of the 8–16 region and lower its amyloidogenic potential, which was confirmed experimentally. Finally, cytotoxicity assays indicate that the 8–16 segment of hIAPP shows enhanced cytotoxicity, which is relieved by the L12R mutation but not by the L12P mutation. Our results indicate that the chameleon properties and the high aggregation propensity of the 8–16 region may significantly contribute to the formation of amyloid fibrils and the overall cytotoxic effect of hIAPP. © 2015 Wiley Periodicals, Inc.

Abstract – The study described in this paper is a part of a cross-sectional study which focuses on Greek children in preschool and middle school age and to primary school teachers' concepts and classifications regarding animals and the associated values attached in concepts and classifications; i.e. which entities categorize as animals and which are the categorization criteria they use and if they differ with the course of age. The research was conducted with group and individual interviews and proper modifications of Interview about Instances (IaI) technique. Various groups of children and primary school teachers as a representative group of adults were interviewed for the meaning of the concept "animal", and the constant comparative method was employed to analyze data. Key findings in children ideas are the recording of a limited range of entities, which are categorized as animals, the use of sensory criteria mainly for deciding about the categorization, and especially the humanoriented course of perceptions. Findings indicate that the meaning of the concept of "animal" that both, children and teachers possess is restricted and anthropocentric, as it appears a universal denial of human categorization in animal kingdom. Nonetheless, it seems that the anthropocentric ideas of school children and adults differs qualitatively, as school children, besides taking more anthropocentric stands compared to adults, they are not led so much by ideological and ethical motives in their decisions, a fact that seems to be developed in lateral stages of life. Keywords – Preschool Children, Primary School Pupils, Primary School Teachers, Ideas, Conceptions, Animal.

Relativistic jets in active galactic nuclei (AGN) are among the most powerful astrophysical objects discovered to date. Indeed, jetted AGN studies have been considered a prominent science case for SKA, and were included in several different chapters of the previous SKA Science Book (Carilli & Rawlings 2004). Most of the fundamental questions about the physics of relativistic jets still remain unanswered, and await high-sensitivity radio instruments such as SKA to solve them. These questions will be addressed specially through analysis of the massive data sets arising from the deep, all-sky surveys (both total and polarimetric flux) from SKA1. Wide-field very-long-baseline-interferometric survey observations involving SKA1 will serve as a unique tool for distinguishing between extragalactic relativistic jets and star forming galaxies via brightness temperature measurements. Subsequent SKA1 studies of relativistic jets at different resolutions will allow for unprecedented cosmological studies of AGN jets up to the epoch of re-ionization, enabling detailed characterization of the jet composition, magnetic field, particle populations, and plasma properties on all scales. SKA will enable us to study the dependence of jet power and star formation on other properties of the AGN system. SKA1 will enable such studies for large samples of jets, while VLBI observations involving SKA1 will provide the sensitivity for pc-scale imaging, and SKA2 (with its extraordinary sensitivity and dynamic range) will allow us for the first time to resolve and model the weakest radio structures in the most powerful radio-loud AGN.

The present paper presents measurements of water flow and suspended particulate material of Pinios River (Thessaly) during the hydrological year 2013/2014. The measurements were carried out in two positions before Pinios enters the agricultural deltaic plain and one inside the delta. Furthermore, an effort is made to estimate the water contribution to Pinios by the springs of Tempi valley and the quantity of water being diverted to the old river bed for irrigation purposes. These measurements were compared to corresponding data from the hydrological year 2012/13 and the significant differences that arose can be attributed to decreased rainfall and probably to the operation of a gate valve in Girtoni, that was initiated in the dry period of 2014.

Sulfate is an essential nutrient with pronounced regulatory effects on cellular metabolism and proliferation. Little is known, however, about how sulfate is sensed by cells. Sul1 and Sul2 are sulfate transporters in the yeast Saccharomyces cerevisiae, strongly induced upon sulfur starvation and endocytosed upon addition of sulfate. We reveal Sul1,2-dependent activation of protein kinase A (PKA) targets upon sulfate-induced exit from growth arrest after sulfur starvation. We provide two major arguments in favor of Sul1 and Sul2 acting as transceptors for signaling to PKA. First, the sulfate analogue, D-glucosamine 2-sulfate, acted as a non-transported agonist of signaling by Sul1 and Sul2. Second, mutagenesis to Gln of putative H+-binding residues, Glu427 in Sul1 or Glu443 in Sul2, abolished transport without affecting signaling. Hence, Sul1,2 can function as pure sulfate sensors. Sul1E427Q and Sul2E443Q are also deficient in sulfate-induced endocytosis, which can therefore be uncoupled from signaling. Overall, our data suggest that transceptors can undergo independent conformational changes each responsible for triggering different downstream processes. The Sul1 and Sul2 transceptors are the first identified plasma membrane sensors for extracellular sulfate. High-affinity transporters induced upon starvation for their substrate may generally act as transceptors during exit from starvation.

Magnetoresistance effects observed in ferromagnet/superconductor (FM/SC) hybrids, FM/SC bilayers (BLs) and FM/SC/FM trilayers (TLs), have attracted much interest. Here, we focus on the stray-fields-based superconducting magnetoresistance effect (sMRE) observed in Co(d(Co))/Nb(d(Nb))/Co(d(Co)) TLs with sufficiently thick Co outer layers so that out-of-plane magnetic domains (MDs) and MDs walls (MDWs) emerge all over their surface when subjected to a parallel external magnetic field, H-ex, equal to the coercive field, H-c. To explore the conditions necessary for maximization of the sMRE, we focus on the different kinds of the stray dipolar fields, H-dip, that emerge at the interior of the out-of-plane MDs and at the boundaries of MDWs; these have a different inherent tendency to create straight and semi-loop vortices, respectively. In the recent literature, the creation of straight and semi-loop vortices has been addressed at some extent both theoretically [Laiho et al., Phys. Rev. B 67, 144522 (2003)] and experimentally [Bobba et al., Phys. Rev. B 89, 214502 (2014)] for the case of FM/SC BLs. Here, we address these issues in FM/SC/FM TLs in connection to the sMRE. Specifically, we focus on an experimental finding reported recently [D. Stamopoulos and E. Aristomenopoulou, J. Appl. Phys. 116, 233908 (2014)]; strong magnetostatic coupling of the FM outer layers is accompanied by an intense sMRE in TLs in which the thickness of the SC interlayer, d(SC), matches the width of MDWs, D-MDWs. To investigate this finding, we employ simulations-modeling and energy-considerations and propose two quantitative criteria that facilitate the creation of straight vortices over semi-loop ones. The first focuses on the maximization of the stray H-dip that occur at the interior of the out-of-plane MDs. The second enables the estimation of a crossover between the preferable creation of one kind of vortices over the other. Both criteria respond well, when tested against experimental results. These generic criteria on the interference between d(SC) and D-MDWs can assist the design of cryogenic devices based on FM/SC/FM TLs. (C) 2015 AIP Publishing LLC.

Magnetoresistance is a multifaceted effect reflecting the diverse transport mechanisms exhibited by different kinds of plain materials and hybrid nanostructures; among other, giant, colossal, and extraordinary magnetoresistance versions exist, with the notation indicative of the intensity. Here we report on the superconducting magnetoresistance observed in ferromagnet/superconductor/ ferromagnet trilayers, namely Co/Nb/Co trilayers, subjected to a parallel external magnetic field equal to the coercive field. By manipulating the transverse stray dipolar fields that originate from the out-of-plane magnetic domains of the outer layers that develop at coercivity, we can suppress the supercurrent of the interlayer. We experimentally demonstrate a scaling of the magnetoresistance magnitude that we reproduce with a closed-form phenomenological formula that incorporates relevant macroscopic parameters and microscopic length scales of the superconducting and ferromagnetic structural units. The generic approach introduced here can be used to design novel cryogenic devices that completely switch the supercurrent 'on' and 'off', thus exhibiting the ultimate magnetoresistance magnitude 100% on a regular basis.

We report the detection of three novae in recent XMM-Newton observations of the M31 disk (see also ATel #8227). Two 100-ks observations were carried out on 2015-06-28 (ObsID 0763120101; June) and 2015-08-11 (ObsID 0763120301; August) and have been analysed using the standard data reduction software.

We consider a two node supply chain with a rational manufacturer-retailer pair, in which the retailer has private information that affects the nodes[U+05F3] reservation levels. Quantity discounts offered by the manufacturer is the mechanism we propose in order to achieve reduced costs for both supply chain nodes. We derive analytical expressions of the quantity discounts that minimize the manufacturer[U+05F3]s costs, while enabling the establishment of the business. Furthermore, we show that perfect coordination is possible even under asymmetric information. Sensitivity analysis and numerical examples offer evidence of the robustness of the results and of the potential of the approach for applications to real-life business ventures. © 2014 Elsevier Ltd.

Syndecan-1 is a proteoglycan that acts as co-receptor through its heparan sulfate (HS) chains and plays important roles in cancer. HS chains are highly variable in length and sulfation pattern. This variability is enhanced by the SULF1/2 enzymes, which remove 6-O-sulfates from HS. We used malignant mesothelioma, an aggressive tumor with poor prognosis, as a model and demonstrated that syndecan-1 over-expression down-regulates SULF1 and alters the HS biosynthetic machinery. Biochemical characterization revealed a 2.7-fold reduction in HS content upon syndecan-1 over-expression, but an overall increase in sulfation. Consistent with low SULF1 levels, trisulfated disaccharides increased 2.5-fold. ERK1/2 activity was enhanced 6-fold. Counteracting ERK activation, Akt, WNK1, and c-Jun were inhibited. The net effect of these changes manifested in G1 cell cycle arrest. Studies of pleural effusions showed that SULF1 levels are lower in pleural malignancies compared to benign conditions and inversely correlate with the amounts of syndecan-1, suggesting important roles for syndecan-1 and SULF1 in malignant mesothelioma.

In tectonically active areas, such as in the northwest Peloponnese of western Greece, geomorphic processes are strongly influenced by active faulting; in many cases such faults cannot be easily identified. In this paper we apply multidisciplinary analysis (morphotectonic indices, neotectonic mapping, geophysical surveys and remote sensing techniques) to map the recently-recognized east–west trending Pineios River normal fault zone with a high degree of accuracy, and to better understand its contribution to the evolution of the ancient region of Elis during Holocene time. Fault activity seems to be related to frequent changes in river flow patterns and to displacements of the nearby shoreline. We argue that fault activity is the main reason for migration of Pineios river mouth as documented for several time periods during historical time. Quantitative constraints on deformation caused by the faulting were applied through the application of the morphotectonic indices proposed in this paper, including drainage network asymmetry and sinuosity, and mountain front sinuosity, all of which indicate that this is a highly active structure. Slip rates calculated to be as high as 0.48 mm/yr for the last 209 ka (based on previously published dating) were verified by applied geophysical methods. The fault surface discontinuity was identified at depth using vertical electrical resistivity measurements and depositional layers of different resistivity were found to be clearly offset. Displacement increases toward the west, reaching an observed maximum of 110 m. The most spectacular landform alteration due to surface deformation is the north–south migration of the river estuary into completely different open sea areas during the late Quaternary, mainly during the Holocene. The sediment transport path has been altered several times due to these changes in river geometry with and the most recent seeming to have occurred almost 2000 years ago. The river estuary migrated to its contemporary position along the southern coast, settled on the hanging wall, inducing retrograding of the northern coast, and settled on the foot wall, with rates reaching the order of 0.52 m/yr, as concluded from historical and recently-acquired remote sensing data.

Examination of the stability, ease of purification and reactivity in the substitution reaction led to a number of optimized conditions with the most convenient involving substitution of triazole derivatives under microwave conditions in the presence of silica gel. Under these conditions, a number of N4-aryl-substituted $\beta$-D-glucopyranosylcytosines were prepared as potential inhibitors of glycogen phosphorylase, a molecular target for type-2 diabetes mellitus.

This paper studies subjective priorities for the data amounts in the processing of geopolitical data according to Mazis Ioannis Th., theoretical paradigm of Systemic Geopolitical Analysis. After defining geopolitical plans and geopolitical focus sets, they are introduced geopolitical preferences and geopolitical management capacities. The geopolitical rational choice is studied, as well as the geopolitical preference -capacity distributions. Then, they are investigated geopolitical contrasts of subjective priorities by several geopolitical operators, and it is shown that there are cores and equilibrium of geopolitical contrasts, the study of which may provide useful information.

Relativistic jets can be modeled as magnetohydrodynamic flows. We analyze the related equations and discuss the involved acceleration mechanisms, their relation to the collimation, to the jet confinement by its environment, and to possible rarefaction waves triggered by pressure imbalances.

Survival for patients with multiple myeloma has increased. Both melphalan and lenalidomide are associated with subsequent development of myelodysplasia. We reviewed the cases of all patients with multiple myeloma who had subsequent development of myelodysplastic syndrome (MDS) or acute non-lymphoblastic leukemia (ANLL) during a 12-year period in three centers. Of 55 patients identified, two received only lenalidomide before myelodysplasia developed. The median time between the diagnoses of multiple myeloma and MDS/ANLL was 52.7 months. Median survival after the diagnosis of MDS or ANLL was 6.7 months. Treatment of MDS comprised allogeneic stem cell transplant in eight patients (median survival, 219 days; one patient alive at 624 days) and a hypomethylating agent in 21 patients (response of stable or better in five patients). Myelodysplasia remains a devastating complication of therapy for multiple myeloma, with short survival and poor response rates to available modalities. © 2014 Informa UK, Ltd.

Robust Dye Sensitized Solar Cells have been prepared employing liquid electrolytes using ethyl isopropyl sulfone (EiPS) high boiling point solvent. The cells were tested for their durability under harsh thermal stressing conditions of 85 °C and prolonged ageing time, 3000 h in the dark. The use of EiPS outperforms stability-wise the typical methoxypropionitrile MPN solvent, improving the cell stability from 38 to 75%. For both solvents, the physicochemical analysis infers the thermal degradation of the cell with the main changes occurring in the first 300 h of ageing. This was attributed to partial triiodide loss which reduces short circuit photocurrent and leads to formation of luminescent species in the electrolyte that affects the TiO2 surface and reduces open circuit photovoltage. The degradation effects were notably supressed by the use of the more stable EiPS solvent, where it was possible to optimize the iodine content in the redox mediator. It has been thus confirmed that iodine concentration as low as 0.05 M in the EiPS electrolyte is slightly preferable in terms of stability and device performance, comparing with higher concentrations, 0.1 and 0.15 M, respectively. © 2015 Elsevier Ltd.

We call monomer a B-DNA base-pair and study electron or hole oscillations in monomers, dimers and trimers. We employ two Tight Binding (TB) approaches: (I) at the base-pair level, using the on-site energies of the base-pairs and the hopping parameters between successive base-pairs and (II) at the single-base level, using the on-site energies of the bases and the hopping parameters between neighboring bases. With (II), for monomers, we predict oscillations with frequency f ≈ 50-550 THz. With (I), for dimers, we predict oscillations with f ≈ 0.25-100THz, for trimers made of identical monomers f ≈ 0.5-33 THz. In other cases, the oscillations may be not strictly periodic, but Fourier analysis shows similar frequency content. For dimers, we compare approaches (I) and (II). Finally, we present calculations with (III) RealTime Time-Dependent Density Functional Theory (RT-TDDFT) for the adenine-thymine (A-T) and the guanine-cytosine (G-C) base-pairs. It seems that a non conventional source or receiver of electromagnetic radiation with f from fractions to THz to just below PHz could be envisaged.

Biomedical & Health Informatics (BMHI) is relatively new in Arab States. However, several programs/ tracks are running, with high promises of expansion. Programs are evaluated by national authorities, not by a specialized body/association. This does not always mean that the program is of an international standard. One of the possible ways of ensuring the quality of these programs is to be evaluated by international agencies. The International Medical Informatics Association (IMIA) has the expertise in the evaluation BMHI education programs. Accredited programs staffs will have the opportunities for Internationalization and to be engaged with other top-notch organizations, which will have great impacts on the overall implementations of the BMHI in the Arab World. The goal of this document is to show to Arab Universities (pilot: Egypt) how to apply for IMIA Accreditation for their programs.
