The interaction between acoustic breathing modes and optical Mie resonances in a spherical particle made of a chalcogenide glass material is investigated by means of rigorous calculations, correct to any order in the acousto-optic coupling parameter. Our results reveal the occurrence of strong effects beyond the linear-response approximation, which lead to enhanced modulation of light by acoustic waves through multiphonon exchange mechanisms when both photons and phonons have a very long lifetime inside the particle.
For decades, parenteral drugs, such as the low molecular weight heparins and unfractionated heparins or vitamin K antagonists, have been used as anticoagulants for prevention of venous thromboembolism following major lower limb surgery. However, these regiments have limitations that rendered the quest for new anticoagulants mandatory. Recently, research has been focused on the development of orally active small molecules that directly target thrombin or activated factor X (FXa). These regiments exhibit a number of characteristics that an "ideal" anticoagulant should possess. Currently, two agents, dabigatran etexilate and rivaroxaban, which inhibit thrombin and FXa, respectively have been approved in the European Union and Canada for venous thromboprophylaxis in patients undergoing elective hip- or knee-replacement surgery. Other agents are at an early or late stage of clinical evaluation. In this study, we summarize the current evidence for these new developed or under development drugs regarding their applications in the filed of lower limb orthopaedic surgery.
Areas covered in this review: In this review, we present the classic approach of bioequivalence assessment, some situations of special importance such as the role of metabolites and highly variable drugs, and the current regulatory state in North America and Europe. Special emphasis is given to the methods proposed for solving the problems caused by high variability such as multiple-dose studies, replicate designs, individual bioequivalence and the widening of bioequivalence limits. Other issues discussed include the concept of biowaivers and the rising field of the equivalence of biologicals (biosimilars). What the reader will gain: The reader will gain an understanding of why bioequivalence assessment is necessary, how it is performed and what one should be aware of when planning to conduct a bioequivalence study. Take home message: The aim of bioequivalence studies is to ensure comparable in vivo performance of two drug products. This is accomplished by performing an appropriate clinical study which should be capable of ensuring the drug's safety and efficacy for consumers with less human exposure and costs of producing.
Summary form only given. Megawatt gyrotrons are found to suffer from various RF oscillations in the beam tunnel prior to the desired interaction zone (the cavity). The development of such parasitics degrades the beam quality reducing the efficiency of the cyclotron interaction and the overall produced power. Furthermore, it affects the stability of operation. Several design approaches have been implemented in order to suppress the parasitic modes; most of them involve the increase of the dissipation in the beam tunnel by means of lossy ceramic materials. However, despite the increased losses, parasitic oscillations still appear in several new designs, especially when the produced power and/or operating frequency is increased. In this work, we employ the numerical code FISHBONE, as well as the commercial simulation software CST STUDIO SUITE in order to study the parasitic modes which appear in a gyrotron beam tunnel. Furthermore, the effect of the geometry of the structure as well as the various design parameters on the parasitic modes is studied, in order to identify the origin and properties of the parasitic oscillations.

CulturalIdentityand Olympic Sports. In the last decades accelerated and unrestrained structural and institutional changes—on an institutional level— have been shattering significant cultural spheres such as class, gender, nationality, nation, and so forth. Today, due to social transformations individual/personal identities are changing and undermining, our sense of self as complete subjects. Namely, the social subject is losing his/her autonomy and self-sufficiency. Identity is no longer formulated on the basis of the social subject’s inner nucleus but is constructed in the interrelations of the self with the social values, meanings and symbols (culture) of the world in which we live and act in [Hall, Held, McGrew 1992]. Social identity is no longer focused on the self as the centre but on the social-cultural environment and as a result identities are being transformed due to structural and institutional changes. The postmodern social subject, in this framework and as a rule, cannot have a stable, static or permanent identity. The social subject— athlete, individual as well as diverse social groups— is confronted with different representations according to socio-cultural conditions. Olympic sports, as a relatively autonomous socio-cultural system, exercise a dynamic influence on the social subject— who acts and communicates within its structures— in the construction of personal/individual identities as well as collective identities. For example, since 1981 the changes that came about with the official recognition of the commercialization of Olympic activity, for some meant deviance and for others adaptation to transforming-evolving social processes. Significant here are the changes regarding Olympic social reality— the material and structural conditions that influence the formation of identity— which affect the active participants as well as the passive ones. In our postmodern period, identities are continuously formed, transformed and reconstructed in relation to the ways that we are represented or addressed in the cultural system that surrounds us (Donnelly, Young 1988).
Keywords: globalization, cosmopolitanism, ecumenical values, collective identity, diverse identities, sport identity.
In Greece, there is no officially organized training in clinical chemistry for scientists. The Greek Society of Clinical Chemistry-Clinical Biochemistry decided to organize an intensive educational program of 18 seminars on clinical chemistry content as it is described in the EC4 Syllabus. The duration of each seminar was about 6 hours and consisted of 6 to 9 lectures. At the end of each seminar there was a voluntary written examination, comprised of 24 multiple choice questions. Successful completion of the Educational program was leading to a Certificate of Competence. Two cycles of the 18 seminars were performed: 1st cycle from October 2003 to December 2005 and 2nd cycle from March 2005 to October 2007. One hundred eighty nine colleagues was the mean attendance per seminar for the seminars of the 1st cycle and 38 colleagues for the seminars of the 2nd cycle. The mean participation to the examination for each seminar was almost 80% for the 1st cycle and 68% for the 2nd cycle. More than 80% of the participants performed Good or Very good in the examination in both cycles. It is estimated that more than 40% of the scientists who practice Clinical Chemistry in Greece, participated to this educational activity. This program is now provided as an e-learning application, and it is open for all scientists who want to follow the discipline of clinical chemistry.
Background: Randomized studies have shown that bevacizumab combined with taxane-based regimens increases response rates and prolongs progression-free survival (PFS) of patients with metastatic breast cancer (MBC). However predictive or prognostic biological markers that identify the appropriate target population, thus improving the cost-effectiveness ratio of this treatment, are still needed. Patients and Methods: Retrospectively, 124 patients with MBC treated either with paclitaxel 90 mg/m2 weekly x12 plus bevacizumab 10 μg/kg every 2 weeks or 15 μg/kg every 3 weeks (85 patients) or paclitaxel 175 mg/m2 plus bevacizumab 15 μg/kg every 3 weeks for 6 cycles (36 patients) were identified. Additionally, the prognostic significance of a panel of key biological markers was evaluated centrally by immunohistochemistry (IHC) in 88 evaluable patients. Results: More than two thirds of the patients completed chemotherapy, as planned. The response rate was almost identical (55.3% vs. 55.6%) in the patients treated with weekly or 3-weekly paclitaxel, respectively. After a median follow-up time of 23 months, the median PFS of the study population was 13 months, while median survival had not yet been reached. Common severe adverse events were neutropenia (33%), neuropathy (18.6%) and metabolic disturbances (17.6%). The incidence of hypertension of all grades was 28.1%. High expression of vascular endothelial growth factor (VEGF) receptor 3 (VEGFR3) was associated with clinical response, while high expression of VEGFR1 was associated with poor survival. Conclusion: The safety and activity of the combination of bevacizumab with paclitaxel given either weekly or 3-weekly in patients with MBC is confirmed.
Dispilio is a lakeside settlement by the Orestias Lake, Kastoria, northern Greece. The site was inhabited from the Middle Neolithic to the Chalcolithic, with some surface evidence of Bronze Age occupation. Microfacies analysis of the sediments, supported by a suite of environmental indices, has provided detailed paleoenvironmental data and elucidated the main processes involved in the formation of the site and its history of occupation. The settlement was established on the lakeshore, on a shallow sand ridge and a shore marsh. Initially, houses were built on raised platforms above the water. After a major conflagration, a range of depositional microenvironments were established that caused local changes in the sedimentation rate. Therefore, some areas quickly emerged and became dry land, while some others continued to be flooded as part of the transitional supra-littoral environment. On the dry land, houses were built directly on the ground, whereas in the transitional areas houses continued to be built on raised platforms. Thus, gradually, a mound was formed and further shaped by subsequent lake-level fluctuations. One of the lake-level rises is tentatively related to the abandonment of the mound in the Chalcolithic and the development of a hardpan on its surface. There is also evidence of later occupation during the Bronze Age in the form of a few, mostly surface, archaeological remains.
Background. Esophagogastroduodenoscopy (EGD) and colonoscopy (CS) can evoke anxiety, embarrassment, and discomfort. These concerns can culminate in panic attacks, which may traumatize patients and significantly decrease their compliance to the procedure. The objective of this study was to evaluate the relationship between preendoscopic anxiety and the possibility of a panic attack during an elective gastrointestinal endoscopy (EGE). Methods. The study population comprised of 79 Greek outpatients. The examination was carried out without the use of conscious sedation. Patients' anxiety levels were assessed before the procedure using the Greek version of the Spielberger State-Trait Anxiety Inventory (STAI-Y). Results. Seventy-nine patients were enrolled: 45 EGD and 34 CS. Females had higher state and trait anxiety levels than males (48.14 ± 7.94 versus 44.17 ± 7.43, P < 0.05; and 43.68 ± 6.95 versus 39.86 ± 7.46, P < 0.05). Patients who experienced panic attack had significantly higher levels of both trait and state anxiety, compared to those who were panic-free. There was no significant relationship between panic attacks and sex or type of procedure. Conclusions. Patients who experience panic attacks during endoscopic procedures appear to have significantly higher anxiety levels before the procedure. Administering the STAI questionnaire prior to the endoscopy seems to be a useful screening method for vulnerable patients.
Summary form only given. Coaxial cavity gyrotrons with axial corrugated insert are able to provide high-frequency microwave power in the MW region. The insert reduces the voltage depression and enhances the mode-selectivity of the cavity. Choosing the insert's radius and corrugation parameters properly, the parasitic modes are more easily suppressed. A major constraint in the design of such resonators is the heating of the structure due to the dissipation of part of the generated RF power of 2-3kW/cm2, whereas for the inner one this limit is up to ten times lower. The EU 2 MW, 170 GHz coaxial gyrotron cavity has been designed using the Surface Impedance Model (SIM) to calculate the ohmic loading of the insert. However, comparisons of SIM results with those obtained by the full-wave Space Harmonics Method (SHM) revealed significant discrepancies in the calculated ohmic loading. In this work, we perform a parametric study of the ohmic loading using SHM and SIM. Possible optimization, by means of minimization of ohmic losses and mode competition, of the EU coaxial gyrotron cavity is investigated.
{Cow's milk is one of the most common causes of food allergy. In two-thirds of patients, adverse symptoms following milk ingestion are caused by IgE-mediated allergic reactions, whereas for one-third, the mechanisms are unknown. Aim of this study was to investigate whether patients suffering from non-IgE-mediated cow's milk protein intolerance can be distinguished from persons without cow's milk protein intolerance based on serological measurement of IgG and IgA specific for purified cow's milk antigens.|We determined IgG(1-4) subclass and IgA antibody levels to purified recombinant αS1-casein, αS2-casein, β-casein, κ-casein, α-lactalbumin, and β-lactoglobulin in four patient groups by ELISA: Patients with IgE-mediated cow's milk allergy (CMA

INTRODUCTION: Correlations between cephalometric measurements are frequently assumed to represent biologic associations. However, a significant portion of such correlations might arise from purely geometric dependencies, when measurements share common landmarks. Analytic calculation of this topographic component is difficult. The purpose of this study was to propose a permutation method for evaluating the topographic component of cephalometric correlations.
METHODS: The method consisted of creating a virtual sample of cephalometric tracings (landmark configurations) from the original biologic sample under investigation. Each novel landmark configuration was constructed by assigning coordinates to the cephalometric points; the coordinates of each point were taken randomly from the original sample, each from a potentially different subject. Correlation analysis was performed separately on both samples and the results compared. Biologic meaning was ascribed only when there was a significant difference in correlation values between the samples. Confidence intervals for assessing statistical significance were calculated by using a randomization approach. The method was tested on a sample of 170 radiographs to evaluate the correlation between cranial base angle (NSBa) and angles SNA and SNB, as well as between ANB angle and the Wits appraisal.
RESULTS: No biologic association was found between ANB and Wits, or between NSBa and SNA. The biologic correlation between NSBa and SNB was statistically significant but low (r(2) = 12%).
CONCLUSIONS: Topographic associations between cephalometric measurements are ubiquitous and difficult to assess. The proposed method enables evaluation of their relative strength without the need for analytic solutions.

New CCD light curves of the recently detected eclipsing variable GSC 4589-2999 were obtained and analysed using the Wilson-Deninney code. Spectroscopic observations of the system allowed the spectral classification of the components and the determination of their radial velocities. The physical properties and absolute parameters of the components and an updated ephemeris of the system are given.
We present a detailed analysis of the optical modes and light propagation in photonic crystals consisting of chiral spheres in a nonchiral isotropic medium, calculated by the full electrodynamic layer-multiple-scattering method. It is shown that resonant modes of the individual spheres give rise to narrow bands that hybridize with the extended bands of the appropriate symmetry associated with light propagation in an underlying effective chiral medium. The resulting photonic dispersion diagrams exhibit remarkable features, peculiar to a system that possesses time-reversal but not space-inversion symmetry, which are analyzed in terms of group theory. In particular, we reveal the occurrence of strong band bending away from the Bragg points with consequent negative-slope dispersion inside the first Brillouin zone, slow-photon bands, and frequency gaps. The calculated band structure is discussed in conjunction with relevant reflection diagrams, providing a consistent interpretation of the underlying physics.
We report on the occurrence and properties of photonic surface states in fcc crystals of metallic nanoshells, by means of full-electrodynamic calculations using the layer-multiple-scattering method, properly extended. Detailed dispersion diagrams of the surface states associated with the (001) and (111) surfaces are calculated for such semi-infinite crystals and corresponding finite slabs, and convergence by increasing the slab thickness is discussed. It is shown that these states can be tuned over a broad frequency range by varying the shell thickness and can be characterized, along high-symmetry directions, according to their symmetry. Absorption in the metallic material limits the propagation length which can, however, be as long as several tens of lattice constants for low-loss metals and relatively broad bands.
Periodic media offer impressive opportunities to manipulate the transport of classical waves namely light or sound. Elastic waves can scatter light through the so-called acousto-optic interaction which is widely used to control light in telecommunication systems and, additionally, the radiation pressure of light can generate elastic waves. Concurrent control of both light and sound through simultaneous photonic-phononic, often called phoxonic, bandgap structures is intended to advance both our understanding as well as our ability to manipulate light with sound and vise versa. In particular co-localization of light and sound in phoxonic cavities could trigger nonlinear absorption and emission processes and lead to enhanced acousto-optic effects. In the present communication, we present our efforts towards the design of different phoxonic crystal architectures such as three-dimensional metallodielectric structures, two-dimensional patterned silicon slabs and simple one-dimensional multilayers, and provide optimum parameters for operation at telecom light and GHz sound. These structures can be used to design phoxonic cavities and study the acousto-optic interaction of localized light and sound, or phoxonic waveguides for tailored slow light-slow sound transport. We also discuss the acousto-optic interaction in onedimensional multilayer structures and study the enhanced modulation of light by acoustic waves in a phoxonic cavity, where a consistent interpretation of the physics of the interaction can be deduced from the time evolution of the scattered optical field, under the influence of an acoustic wave.
OBJECTIVES: To examine the association between physical activity (PA) and Alzheimer disease (AD) course.
BACKGROUND: PA has been related to lower risk for AD. Whether PA is associated with subsequent AD course has not been investigated.
METHODS: In a population-based study of individuals aged 65 years and older in New York who were prospectively followed up with standard neurologic and neuropsychological evaluations (every ~1.5 years), 357 participants i) were nondemented at baseline and ii) were diagnosed with AD during follow-up (incident AD). PA (sum of participation in a variety of physical activities, weighted by the type of activity [light, moderate, and severe]) obtained 2.4 (standard deviation [SD], 1.9) years before incidence was the main predictor of mortality in Cox models and of cognitive decline in generalized estimating equation models that were adjusted for age, gender, ethnicity, education, comorbidities, and duration between PA evaluation and dementia onset.
RESULTS: One hundred fifty incident AD cases (54%) died during the course of 5.2 (SD, 4.4) years of follow-up. When compared with incident AD cases who were physically inactive, those with some PA had lower mortality risk, whereas incident AD participants with much PA had an even lower risk. Additional adjustments for apolipoprotein genotype, smoking, comorbidity index, and cognitive performance did not change the associations. PA did not affect rates of cognitive or functional decline.
CONCLUSION: Exercise may affect not only risk for AD but also subsequent disease duration: more PA is associated with prolonged survival in AD.

OBJECTIVE: Insomnia is frequently underrecognized in medical wards; therefore, we assessed the prevalence and explored medical and psychological variables associated with insomnia. METHOD: The Athens Insomnia Scale and the Hospital Anxiety and Depression Scale (HADS) were completed in 235 inpatients along with demographic data, admission diagnosis, lifetime psychiatric diagnosis and prescribed psychotropics. RESULTS: The overall insomnia prevalence was 37%. Logistic regression showed that HADS anxiety and depression cases and patients with infections were more likely to have insomnia (OR 24.2, 6.1 and 5.4, respectively). CONCLUSIONS: Patients with depressive and mainly anxiety symptoms are more likely to experience insomnia in medical wards. Patients with infections are also likely to have insomnia, independently of depressive and anxiety symptoms, and appropriate interventions should be applied.
We reexamined the total extinction along the sightline of a quasar (J004457+4123) behind the disk of M31 and used a varying total-to-selective extinction ratio in order to obtain a better agreement between its optical spectrum and a composite SDSS spectrum based on input spectra of quasars from DR7 at similar redshifts. The M31 outermost disk predominates (~85%) the total foreground (Milky Way+M31) selective extinction EB-V = 0.30+/-0.05 mag and the derived gas-to-dust ratio is N(H)/EB-V = (3.5+/-0.7)×1020 atcm-2 mag-1.

Between 2004 and 2009, 60 patients with proximal tibial fractures were included in this prospective study. All fractures were treated with the polyaxial locked-plate fixation system (DePuy, Warsaw, IN, USA). Clinical and radiographic data, including fracture pattern, changes in alignment, local and systemic complications, hardware failure and fracture union were analysed. The mean follow-up was 14 (12-36) months. According to the Orthopaedic Trauma Association (OTA) classification, there were five 41-A, 28 41-B and 27 41-C fractures. Fractures were treated percutaneously in 30% of cases. Double-plating was used in 11 cases. All but three fractures progressed to union at a mean of 3.2 (2.5-5) months. There was no evidence of varus collapse as a result of polyaxial screw failure. No plate fractured, and no screw cut out was noted. There was one case of lateral joint collapse (>10°) in a patient with open bicondylar plateau fracture. The mean Knee Society Score at the time of final follow-up was 91 points, and the mean functional score was 89 points. The polyaxial locking-plate system provided stable fixation of extra-articular and intra-articular proximal tibial fractures and good functional outcomes with a low complication rate.
In a previous paper ([1]), we associated a holonomy groupoid and a C*-algebra to any singular foliation (M,ℱ). Using these, we construct the associated pseudodifferential calculus. This calculus gives meaning to a Laplace operator of any singular foliation ℱ on a compact manifold M, and we show that it can be naturally understood as a positive, unbounded, self-adjoint operator on L2(M).

The effects of the geological, tectonic and neotectonic structure and the impact of the human presence and activity on the drainage network of Pineios river are presented here in order to determine the causes of its diversion and the implications to the shoreline. We used, analyzed and evaluated (a) geomorphological, geological, tectonic and neotectonic data of the study area, (b) historical information and archaeological findings from buried and eroded archaeological sites of the wider study area, (c) published data related to drill cores and radiocarbon dates, and (d) remote sensing datasets, as satellite and aerial photos of different capturing periods, as well as real-time kinematic differential GPS measurements for the definition of the current shoreline. It is concluded that the detected shoreline displacements and drainage diversions are the result of the combination of active tectonics and human activity during the last 100 kyrs.
Human kallikrein-related peptidase 14 gene (KLK14) is regulated by androgens and progestins. This gene is expressed in the central nervous system and endocrine tissues such as the breast, prostate and ovary. The differential KLK14 mRNA expression levels are related to several human neoplasias, among them breast cancer. The aim of this study was to analyse the KLK14 expression in breast tissues and to investigate its differential diagnostic and prognostic value in the mammary carcinomas. For this purpose, we isolated total RNA from 70 malignant and 33 benign specimens. After testing RNA quality, we synthesised cDNA by reverse transcription and applied a highly sensitive quantitative real-time PCR (qRT-PCR) method for KLK14 mRNA quantification using the SYBR Green(R) chemistry. HPRT1 was used as a reference gene and the BT20 breast cancer cell line as a calibrator. Relative quantification analysis was performed using the comparative CT method 2-DeltaDeltaCT. KLK14 expression was detected in both types of breast tumours. However, a statistically significant increase of the KLK14 mRNA level was observed in the malignant, compared to the benign tumour samples (p<0.001), highlighting its value in discriminating these breast lesions. Elevated KLK14 expression profiles were associated with higher tumour grade (p=0.043) and size (p=0.007) in cancerous samples. Furthermore, KLK14 mRNA expression showed negative correlation in a statistically significant manner with estrogen receptor status (p=0.024). In accordance with logistic regression models (p=0.012) and receiver-operating-characteristics analysis (p<0.001), KLK14 gene expression could be evaluated as a putative independent diagnostic biomarker in breast tumour biopsies.

Background in Ancient Greek Music Theory and Philosophy. The foundation of musicology as agenuine discipline with a clear-cut subject matter and a well-defined terminology can be traced backto the writings of Aristoxenus of Taras, a pupil of Aristotle. However, its epistemological roots in harmonicsand origin in Pythagorean philosophy reach back until the 6th century. Ad interim the developmentof a melodic notation system acted as a crucial factor to grow musicology into a ̔science’ oflogical reasoning. Interestingly, and still without satisfactory explanation, notation as an adequatemedium of music was brusquely rejected by Aristoxenus.Background in Music Technology and Signal Processing. Besides the thought-provoking fact thatsignal processing as the foundation of modern music technology itself originates from the domain ofharmonic analysis and, similarly, became relevant to ̔musicology proper’ only by extension with adiscrete agency purely logic in nature—i.e. the computer—now, real-time pitch-tracking andpitch-shifting can be used to augment ancient instruments electronically in order to pose archaeologicalquestions and challenge sedimented hermeneutical interpretations.Aims. While re-enacting historical configurations, applied media theory provides an unconventionalframework to interlink both backgrounds anachronistically. In practice, the aim of the present interdisciplinaryapproach is to take issue with common exegeses of the rise of ancient Greek music theory,deliver testable hypotheses to corroborate a modified picture and finally to overcome the outdatedantithesis of Pythagorean vs. Aristoxenian views on music—i.e. numerology vs. phenomenology—propounded since the Hellenistic Period and still prevalent today.Main contribution. The historical background and epistemological circumstances that led to theformation of musicology as a separate field of knowledge are reviewed. During the course of discussiona "pre-Aristoxenian codec of notation" is uncovered and linked with scattered references to thebarbiton-lyre. The acoustical significance of its origin becomes ̔instrumental’ to augment a self-madereconstruction of such an instrument electronically. Hereby a perceptual model of melody isre-enacted that logically connects and unifies theoretical camps previously considered irreconcilable.The technology and methodology necessary to achieve this is described.Implications. Towards the end of the 5th century, many sources ascribe a revolutionary ̔new music’to the advent of frequent modulations and different ̔styles’ of playing techniques. Taking this revolutionseriously, the present paper constructs a history of hearing that proposes a rupture in the ancientGreek sonosphere. Accordingly, the changed strategy of listening is regarded the true cause of theAristoxenian separation of musicology. Today, the ̔kernel’ of this parting can be identified with themore general domain of "time-critical processes" in computation and signal processing whose applicationenables us to understand the subsequent reshaping of music theory and the radical remodellingof its philosophical conception. By extension, this lesson in mousikḗ may make us rethink music asstill a vital epistemological field and may encourage us to form a new research domain possibly calledcomputational archaeomusicology.
Abstract Renal impairment (RI) is a common presenting complication of multiple myeloma associated with significant morbidity and early mortality, while it has been associated with inferior survival in patients treated with conventional regimens. We assessed the impact of RI in 203 unselected consecutive patients treated upfront with novel agents (thalidomide, lenalidomide, bortezomib). RI was assessed by the estimated glomerular filtration rate (eGFR). RI (eGFR <60 mL/min) was present in 93 (45.8%) of patients at diagnosis and was associated with advanced age, advanced International Staging System (ISS) stage, poorer performance status, hypercalcemia, urine Bence-Jones proteinuria, anemia and thrombocytopenia. Myeloma response rates were similar for patients with or without RI. In univariate analysis RI was associated with shorter survival and a higher rate of early death (7% vs. 3.5%); however, when adjusted for other prognostic factors, RI was not independently associated with survival. In conclusion, in unselected newly diagnosed patients treated with novel agent-based therapies, RI is not independently associated with inferior survival, probably due to the significant activity of novel agents even in the context of RI.
Differences in ecological conditions can result in the evolution of dramatic inter-population shifts in whole suites of traits. We studied variation in reproductive output in three lizard populations of the Skyros Wall Lizard (Podarcis gaigeae, Lacertidae) endemic to the Skyros Archipelago (Greece), which live under similar climatic conditions but differ in predation pressure and food availability. Based on the ‘‘island syndrome’’ hypothesis, we predicted that females from island populations would produce larger, but fewer offspring. The study populations differ conspicuously in average body size, with males from the satellite Lakonissi and Diavates islets being respectively 20% and 39% larger than males from the main Skyros Island. Lizards from these predator-free islets produced eggs of larger size than the main Skyros population; however, they also produced significantly larger clutches than the Skyros population (2.31±0.83 and 2.73±1.0 vs. 1.97±0.58 eggs). All inter-population differences in clutch size, clutch volume, and egg size were explained by corresponding differences in average body size of the dams, revealing that across all populations, reproductive effort scaled similarly with maternal body size. There was no evidence of trade-offs between egg size and clutch size as generally encountered in many reptile taxa. The occurrence of this unusual pattern of reproductive investment among islet populations of giants is probably best explained by the occurrence of two underlying drivers: first, the substantial marine subsidies by resident seabird colonies and second, the existence of intense cannibalistic behaviors in the form of attacks to the tail and severe intraspecific predation on juveniles. This suggests that subsidies-driven gigantism in island endemics may free species from such trade-offs and allow a population to maximize reproductive output in multiple, normally conflicting dimensions.
Successful research management requires multifunctional, equal teamwork and efficient coordination, aiming to increase the impact of the research outcomes. Aim of this paper is to present the strategies that have been followed to successfully manage the RN4CAST study, one of the largest multi country research projects ever conducted. The paper focuses on the core research strategies rather than on the administrative management activities also required for the success of this case report. Management of a multi-country nursing survey requires the use of common data collection tools, applicable to every context, research protocols supporting the scope of the research, data models for multi-country analyses and global dissemination strategies.
European legislators and wine producers still debate on the requirement for labeling of wines fined with potentially allergenic food proteins (casein, egg white or fish-derived isinglass). We investigated whether wines fined with known concentrations of these proteins have the potential to provoke clinical allergic reactions in relevant patients.|In-house wines were produced for the study, fined with different concentrations of casein (n = 7), egg albumin (n = 1) and isinglass (n = 3). ELISA and PCR kits specific for the respective proteins were used to identify the fining agents. Skin prick tests and basophil activation tests were performed in patients with confirmed IgE-mediated relevant food allergies (n = 24). A wine consumption questionnaire and detailed history on possible reactions to wine was obtained in a multinational cohort of milk, egg or fish allergic patients (n = 53) and patients allergic to irrelevant foods as controls (n = 13).|Fining agents were not detectable in wines with the available laboratory methods. Nevertheless, positive skin prick test reactions and basophil activation to the relevant wines were observed in the majority of patients with allergy to milk, egg or fish, correlating with the concentration of the fining agent. Among patients consuming wine, reported reactions were few and mild and similar with the ones reported from the control group.|Casein, isinglass or egg, remaining in traces in wine after fining, present a very low risk for the respective food allergic consumers. Physician and patient awareness campaigns may be more suitable than generalized labeling to address this issue, as the latter may have negative impact on both non-allergic and allergic consumers.
Environmental history often reveals the contribution of humans in the modification of natural environment, always in relation with the climatic factors. Archaeological settlements may be preserved through desiccation, however, they are commonly found in floodplain sediments. Archaeological evidences may provide with useful information about the processes and extent of environmental changes, but they may also be used as tools for the analysis of floodplain sedimentation, relative chronology of sedimentation events and for the geomorphological evaluation of the particular archaeological site. The characteristics of archaeological indicators and the deposits in which they occur, may indicate important aspects of their source, transportation way and age. Evidence of river migration may be found in alluvial plains, through careful observations. The study area is located in Kalavrita region in northern Peloponnese. The archaeological excavations carried out revealed the fortification wall of the ancient city of "Kleitor"which is dated between the 3rd and 2nd century BC (Hellenistic Period). It may also provide clues for land surface development, reworking of sedimentary deposits, paleoenvironmental and climatic conditions. Sediments indicating considerable climatic changes are alluvial deposits of considerable thickness, covering areas with human impact. All the aforementioned become a tool for dating the course changes of the rivers and consequently a geomorphological instability. The relationship between geomorphology and history is recognizable also in the settlement distribution. This close relationship between environment and man provides a tool to understanding the landscape evolution from a geomorphological and historical point of view.
Hyaluronan (HA) modulates key cancer cell functions through interaction with its CD44 and receptor for hyaluronic acid-mediated motility (RHAMM) receptors. HA was recently found to regulate the migration of fibrosarcoma cells in a manner specifically dependent on its size. Here, we investigated the effect of HA/RHAMM signaling on the ability of HT1080 fibrosarcoma cells to adhere onto fibronectin. Low molecular weight HA (LMWHA) significantly increased (p
During prostate carcinogenesis the cellular adhesion molecules, i.e.; integrins and cadherins mediate aberrant interactions between glandular epithelial cells and the extracellular matrix. Several integrin α subunits are downregulated, while β subunits are up-regulated. The expression of several cadherins and catenins has specific prognostic value. There is an association between the expression of the E-cadherin/catenin complex and high grade prostate cancer. Clinical trials evaluating the efficacy of integrin antagonists are ongoing with promising results. In this article we update the role of integrins and cadherins in prostate carcinogenesis and evaluate the therapeutic potential of their manipulation.
We have performed the Fourier decomposition analysis of 11-yr V-band light curves of a carefully selected sample of 100 RR Lyrae variables, detected in the central regions of the Small Magellanic Cloud (SMC), with the Optical Gravitational Lensing Experiment, phases II and III. The sample consisted of 84 fundamental mode pulsators (RRab stars) and 16 first-overtone pulsators (RRc stars). The Fourier decomposition parameters were used to derive metal abundances and distance moduli for these RR Lyrae variables. The average metal abundance of the RRab stars on the new scale of Carretta et al. is found to be <[Fe/H]C09>=-1.62 ± 0.41 dex (std, with a standard error of 0.05 dex). The distance modulus of the SMC was found to be <μ>= 18.90 ± 0.18 (std) from the RRab population in a distance scale where the distance modulus of the Large Magellanic Cloud (LMC) is μLMC= 18.52 ± 0.06 (std). The 1σ line-of-sight depth for the RRab stars was found to be σint= 4.13 ± 0.27 kpc, in good agreement with that estimated from red clump stars and eclipsing binaries. There is a clear indication that the metal-poorer and metal-richer objects in the sample may belong to different dynamical structures. The metal-rich stars have smaller scaleheight and could be part of a disc-like structure, while the more metal poor objects could be part of a much thicker structure, such as an inner halo or a bulge component.
Four sampling sites were selected in the area of Velouhi mountain, Greece in order to screen for Pseudomonas syringae isolates with high ice nucleation activity from a ski resort environment. Bacterial isolates (n=147) were obtained from soil and phyllosphere samples. Seven isolates exhibited morphological, biochemical and physiological profile similar to P. syringae. Phylogenetic relationships of the seven isolates were determined by 16S rRNA gene sequencing. Two isolates were phylogenetically affiliated to P. syringae, three to P. viridiflava, one to P. avellanae, and one Pseudomonas strain could not be assigned to a known species. The seven isolates were examined for their ice-nucleation activity properties. Three out of the seven studied isolates exhibited ice nucleation activity from –4.67 to –4.35 ice nuclei per cell, values similar to those obtained from a known ice-nucleation protein producer P. syringae strain and therefore could be used for the production of artificial snow in ski resort areas with short snow periods.
Phospholamban (PLN), the reversible inhibitor of the sarco(endo)plasmic reticulum Ca(2+)-ATPase (SERCA2a), is a key regulator of myocyte Ca(2+) cycling with a significant role in heart failure. We previously showed that the single amino acid difference between human and mouse PLN results in increased inhibition of Ca(2+) cycling and cardiac remodeling and attenuated stress responses in transgenic mice expressing the human PLN (hPLN) in the null background. Here we dissect the molecular and electrophysiological processes triggered by the superinhibitory hPLN in the mouse. Using a multidisciplinary approach, we performed global gene expression analysis, electrophysiology, and mathematical simulations on hPLN mice. We identified significant changes in a series of Na(+) and K(+) homeostasis genes/proteins (including Kcnd2, Scn9a, Slc8a1) and ionic conductance (including L-type Ca(2+) current, Na(+)/Ca(2+) exchanger, transient outward K(+) current). Simulation analysis suggests that this electrical remodeling has a critical role in rescuing cardiac function by improving sarcoplasmic reticulum Ca(2+) load and overall Ca(2+) dynamics. Furthermore, multiple structural and transcription factor gene expression changes indicate an ongoing structural remodeling process, favoring hypertrophy and myogenesis while suppressing apoptosis and progression to heart failure. Our findings expand current understanding of the hPLN function and provide additional insights into the downstream implications of SERCA2a superinhibition in the mammalian heart.
Conditions resulting in insulin resistance, as well as metabolic, immune, and angiogenic perturbations, have been associated with an increased risk of preeclampsia (PE). Our purpose was to assess whether the adipose tissue-secreted hormones adiponectin, which has immune-modulating, metabolic, and angiogenic properties, and leptin, which reflects overall fat mass, are associated with PE risk. We performed a case-control design study within a hospital-based cohort of 368 pregnant women (106 with PE and 262 controls; mean age, 26.6 ± 6.8 years; mean gestational age at admission, 38.2 ± 2.8 weeks) between March 2005 and August 2007 at the Hospital of Pennsylvania University. Serum adiponectin and leptin were measured by radioimmunoassay. Statistical analysis of data was performed using simple and multiple regression analyses. No significant differences in adiponectin or leptin levels between preeclamptic and control pregnant women emerged in univariate analyses (P = .57 and P = .15, respectively). Among preeclamptic women, there were also no differences in adipokines between those with mild and severe disease. Serum adiponectin and leptin were not associated with higher risk of PE before and after adjustment for maternal age, race, primigravida, smoking status, body mass index at screening, gestational age at admission, history of PE, chronic hypertension, and gestational diabetes (odds ratio, 0.93; 95% confidence interval, 0.83-1.04 and odds ratio, 1; 95% confidence interval, 0.97-1.03, respectively). Maternal serum adiponectin and leptin levels, drawn at the time of PE diagnosis, were not associated with PE.
OBJECTIVE: Menopause is associated with weight gain and an increase of cardiovascular risk. The aim of the present study was to estimate serum ischemia-modified albumin (IMA) levels in postmenopausal women and evaluate their association with body mass index (BMI) and coronary artery disease (CAD).
METHODS: The study included 130 non-smoker postmenopausal women aged 43-80: 40 with BMI 26-32 kg/m(2) (Group A), 60 with BMI 21-25 kg/m(2) (Group B), and 30 with documented CAD and BMI 23-29 kg/m(2) (Group C). Serum IMA, albumin, hsCRP and NT-proBNP, glucose and insulin were measured. Homeostasis assessment model score (HOMA) and Quantitative insulin sensitivity index (QUICKI) were co-estimated.
RESULTS: Serum IMA and IMA to albumin ratio were significantly elevated in Group A as compared to Group B (p<0.001) and similar to those of Group C. hsCRP and NT-proBNP did not differ between Groups A and B while they were lower in comparison to Group C (p<0.001). Glucose, insulin and HOMA were elevated in Group A compared to Group B (p<0.001) while QUICKI was lower (p<0.001). In Group A, IMA was positively correlated with BMI, hsCRP, insulin, HOMA and negatively with QUICKI. In postmenopausal women, multivariable regression analysis revealed that obesity was the strongest significant determinant of circulating IMA levels (p<0.001) contributing, therefore, to the elevated serum IMA concentration.
CONCLUSIONS: Postmenopausal obesity is associated with elevated serum IMA possibly due to obesity associated oxidative stress. IMA measurement could provide an assessment of atherosclerotic burden in postmenopausal women. Further clinical evaluation is under investigation.
INTRODUCTION: Sex differences have been identified in antidepressant treatment; however, it remains unclear to what extent pharmacokinetics contributes to these differences. As current antidepressant pharmacotherapy is less than optimal, understanding the role of sex in pharmacokinetics may substantially contribute to a gender-based optimized treatment. AREAS COVERED: An unrestricted PubMed literature search on antidepressant pharmacokinetics and sex was performed. Sex differences in absorption, distribution, metabolism and elimination of antidepressants, as well as the interaction of sex with age, genetic polymorphisms and gonadal hormones are discussed. We also provide an overview of how each antidepressant presents a particular sex-differentiated pharmacokinetic profile. Most antidepressants present to some extent pharmacokinetic sex differences, which often are further accentuated by gonadal hormones. In most cases, women, particularly elderly women, are expected to have higher exposure to antidepressants when dosed in a similar way as men. EXPERT OPINION: Although the available pharmacokinetic evidence indicates that women should receive lower doses of antidepressants and men should receive higher doses, current guidelines do not recommend dose adjustment, because these sex differences are considered to be clinically insignificant. Unless we understand the link between pharmacokinetics and pharmacodynamics of antidepressants, it will be difficult to determine whether sex differences are of clinical importance or not. Thus, further systematic and particularly focused research is needed on sex differences in pharmacokinetics.

Women are more susceptible than men to certain stress-related psychiatric disorders, such as depression. Preclinical studies aim to understand these sex differences by studying male and female rats in stress models. In this chapter, we review sex differences in behavioural aspects, as well as neurochemical and neurobiological findings derived from acute, repeated and chronic stress models. In particular, we focus on sex differences in depressive-like symptomatology expressed in the forced swim test, the chronic mild stress (CMS) and the learned helplessness models, the Flinders Sensitive Line rats (FSL), which is a genetic model of depression and in the lipopolysaccharide (LPS)-induced sickness behaviour, a putative inflammatory model of depression. Also, sex differences in stress effects on learning and memory parameters are discussed, because cognitive alterations are often seen in sex-differentiated psychiatric disorders. The observed behavioural alterations are often linked with abnormalities in the endophenotype, such as in hormonal, neurochemical, immune and neuroplasticity indices. From these data, it is clear that all stress models have strengths and limitations that need to be recognized in order to use them effectively in the investigation of sex differences in affective disorders.

The present study investigates whether the human mandible is sexually dimorphic during early postnatal development and whether early dimorphic features persist during subsequent ontogeny. We also examine whether mandibular dimorphism is linked to dimorphism of dental development. Dense CT-derived mandibular meshes of 84 females and 75 males, ranging from birth to adulthood, were analyzed using geometric morphometric methods. On the basis of the specimen's chronological ages and mineralization stages of the deciduous and permanent teeth, we compute dental age as proxy for dental development by the additive conjoint measurement method. By birth, males have, on average, more advanced age-specific shapes than females. However, sex differences decrease quickly as females catch up via a different association between shape and size. This leads to an almost complete reduction of sexual dimorphism between the ages of 4 and 14. From puberty to adulthood, males are characterized by allometric shape changes while the shape of the female mandible continues to change even after size has ceased to increase. Dimorphism of dental maturation becomes visible only at puberty. Sexual dimorphism, concentrated at the ramus and the mental region during the earliest ontogenetic stages and again at adulthood, is not associated with the development of the teeth. At puberty there is a simultaneous peak in size increase, shape development, and dental maturation likely controlled by the surge of sex hormones with a dimorphic onset age. We argue that the infant and adult dimorphism of the mental region may be associated with the development of supralaryngeal structures.
Par le biais de l’étude du cas de la professeure de philosophie Simone Weil (1931-1940), cet article s’intéresse à faire émerger un aspect du versant féminin de la transgression des normes au sein de l’Université de l’entre-deux-guerres. Il prend appui sur le point de vue des autorités universitaires tel qu’il se dessine surtout à travers la lecture des documents conservés dans le dossier de carrière de la fonctionnaire. Le présent travail tente aussi d’interpréter, sous un éclairage différent, les faits relatés par ses biographes.L’analyse prend tout d’abord en considération le double registre de la langue utilisée par l’administration : discrétion dans notices annuelles, libération du langage dans la correspondance. La deuxième partie du travail enregistre les griefs les plus graves formulés contre la philosophe. L'administration fustige, en premier lieu, les rapports que Weil entretient avec ses collègues et sa conduite irrespectueuse à l’égard de sa directrice. On lui reproche en outre de ne pas respecter les programmes officiels et de transformer sa chaire en tribune où elle défend ses idées politiques et sociales : elle viole ainsi le principe de neutralité scolaire. La troisième partie de l’étude nous entraîne sur le terrain des activités militantes de la professeure. Les rapports de police, la correspondance de ses chefs administratifs, des articles de presse, enfin, se réfèrent surtout à sa participation aux grèves ouvrières organisées à la ville du Puy. L’examen du discours déployé dans ces documents révèle que le sexe de la militante gêne davantage que sa fonction : Weil provoque en premier lieu parce qu’elle est femme, donc non citoyenne, et ensuite parce qu’elle est professeure de l’enseignement public.Dans la dernière partie sont mis en évidence les « silences » du dossier de Weil après 1933, ce qui laisse supposer qu’il fut systématiquement dépouillé après cette date. Malgré les vides dans la documentation, les documents repérés laissent percevoir clairement le point de vue de l’administration au sujet de la place de Simone Weil dans l’Université : celle-ci est, à tout moment, présentée comme une intruse, comme une déplacée, une « indésirable ».
The Hellenic subduction zone displays well-defined temporal and spatial variations in subduction rate and offers an excellent natural laboratory for studying the interaction among slab buoyancy, subduction rate, and tectonic deformation. In space, the active Hellenic subduction front is dextrally offset by 100–120 km across the Kephalonia Transform Zone, coinciding with the junction of a slowly subducting Adriatic continental lithosphere in the north (5–10 mm/yr) and a rapidly subducting Ionian oceanic lithosphere in the south (∼35 mm/yr). Subduction rates can be shown to have decreased from late Eocene time onward, reaching 5–12 mm/yr by late Miocene time, before increasing again along the southern portion of the subduction system. Geodynamic modeling demonstrates that the differing rates of subduction and the resultant trench offset arise naturally from subduction of oceanic (Pindos) lithosphere until late Eocene time, followed by subduction of a broad tract of continental or transitional lithosphere (Hellenic external carbonate platform) and then by Miocene entry of high-density oceanic (Ionian) lithosphere into the southern Hellenic trench. Model results yield an initiation age for the Kephalonia Transform of 6–8 Ma, in good agreement with observations. Consistency between geodynamic model results and geologic observations suggest that the middle Miocene and younger deformation of the Hellenic upper plate, including formation of the Central Hellenic Shear Zone, can be quantitatively understood as the result of spatial variations in the buoyancy of the subducting slab. Using this assumption, we make late Eocene, middle Miocene, and Pliocene reconstructions of the Hellenic system that include quantitative constraints from subduction modeling and geologic constraints on the timing and mode of upper plate deformation.
BACKGROUND: Heat shock proteins (Hsp) are known to enhance cell survival under various stress conditions. In the heart, the small Hsp20 has emerged as a key mediator of protection against apoptosis, remodeling, and ischemia/reperfusion injury. Moreover, Hsp20 has been implicated in modulation of cardiac contractility ex vivo. The objective of this study was to determine the in vivo role of Hsp20 in the heart and the mechanisms underlying its regulatory effects in calcium (Ca) cycling. METHODS AND RESULTS: Hsp20 overexpression in intact animals resulted in significant enhancement of cardiac function, coupled with augmented Ca cycling and sarcoplasmic reticulum Ca load in isolated cardiomyocytes. This was associated with specific increases in phosphorylation of phospholamban (PLN) at both Ser16 and Thr17, relieving its inhibition of the apparent Ca affinity of SERCA2a. Accordingly, the inotropic effects of Hsp20 were abrogated in cardiomyocytes expressing nonphosphorylatable PLN (S16A/T17A). Interestingly, the activity of type 1 protein phosphatase (PP1), a known regulator of PLN signaling, was significantly reduced by Hsp20 overexpression, suggesting that the Hsp20 stimulatory effects are partially mediated through the PP1-PLN axis. This hypothesis was supported by cell fractionation, coimmunoprecipitation, and coimmunolocalization studies, which revealed an association between Hsp20, PP1, and PLN. Furthermore, recombinant protein studies confirmed a physical interaction between AA 73 to 160 in Hsp20 and AA 163 to 330 in PP1. CONCLUSIONS: Hsp20 is a novel regulator of sarcoplasmic reticulum Ca cycling by targeting the PP1-PLN axis. These findings, coupled with the well-recognized cardioprotective role of Hsp20, suggest a dual benefit of targeting Hsp20 in heart disease.
Paros Island is part of the complex of Cyclades Islands, situated in the central Aegean Sea, Greece. The climate of Paros Island is representative of the Mediterranean type, with abrupt rainfalls and lower temperatures during winters and long term sunshine accompanied by dry periods during the summer, conditions able to cause severe problems on the land. The island's low vegetation leaves the ground exposed to erosion. Also, the recent change from the local's people agricultural activities to touristic ones-especially the abandonment of the agricultural terraces during the last 50 years-has influenced the soil cover of the island in an unfavorable way, leading to total soil loss and exposure of the bedrock in many areas. Aggravating this fact, the island's steep slopes render soil regeneration almost impossible. The transferred soil is either moving towards the small alluvial plains or, in most cases, is being deposited directly to the sea. In the following paper an effort is being made to depict the currently existing situation on the island by delineating the areas still appearing to be at a high risk for erosion and to estimate the average amount of soil loss. For the later, the Universal Soil Loss Equation (USLE) was tested on the data of the island. The application of the USLE was implemented via MapInfo and ArcGIS Tools Software. The main result of the present study is that it outlines the areas where severe erosion might occur and also gives a good example for land users what is the best scenario o protect their land against erosion and which plant they should use or avoid to protect their soil from erosion.
Η εποποιία του 1940 συγκλόνισε τους Έλληνες της Αμερικής, οι οποίοι παρακολουθούσαν αγωνιωδώς τις δραματικές εξελίξεις μέσα από τον ελληνοαμερικανικό τύπο, τις αφηγήσεις των μεταναστών εθελοντών και τις προκηρύξεις που διέρρεαν στις ελληνοαμερικανικές κοινότητες. Η ελληνοαμερικανική δραματουργία στο διάστημα του Β΄ Παγκοσμίου Πολέμου κατόρθωσε να υπερβεί τις ιδεολογικές της αντιφάσεις και να ακολουθήσει μια κοινή δραματουργική γραμμή. Κυριαρχεί ο ρομαντισμός και οι έννοιες της αυτοθυσίας και της ελευθερίας. Θεματολογικά τα έργα πραγματεύονται τον ελληνοαλβανικό πόλεμο και τα χρόνια της Κατοχής, εμπλουτισμένα με στομφώδη ρητορεία και υπερβολική συναισθηματολογία, βρίθουν από συγκινησιακά στοιχεία φορτισμένα από πατριωτισμό. Στον τομέα της θεατρικής πρακτικής τη δεκαετία του 1940 επικρατούν οι ερασιτεχνικοί θίασοι έναντι των επαγγελματικών, οι οποίοι επιλέγουν το πατριωτικό ρεπερτόριο και τις διάσημες αθηναϊκές πολεμικές οπερέτες. Έλληνες ηθοποιοί, οι οποίοι προπολεμικά συμμετείχαν ενεργά στους γηγενείς ελληνοαμερικανικούς θιάσους, είτε καταξιώνονται σε νευραλγικές θέσεις των ελληνικών κοινοτήτων, είτε επιστρέφουν στην Ελλάδα, στηρίζοντας τον Αγώνα της Αντίστασης.
Ο Αριστείδης Παρίσης, ψευδώνυμο του ηθοποιού Αριστείδη Σακκά, γεννήθηκε και μεγάλωσε στο Ληξούρι της Κεφαλλονιάς στα τέλη του 19ου αι. Παντρεύτηκε τη Δέσποινα Παρίση και απέκτησε δύο κόρες : την Κατίνα και την Ευαγγελία. Ως έφεδρος αξιωματικός υπηρέτησε στην Εθνική Άμυνα της Θεσσαλονίκης. Λόγω των πολιτικών αντιβασιλικών φρονημάτων του καταδιώχθηκε, τόσο από τη Θεσσαλονίκη, όσο και από τη Λάρισα όπου είχε καταφύγει. Παράλληλα δρούσε ως ηθοποιός σε θιάσους, όπως στο θίασο Σαμαρτζή, αλλά και ως θιασάρχης. Τα μέλη της οικογένειάς του συγκροτούσαν, κατά κύριο λόγο, το θίασο. Οι κόρες του έπαιζαν στην σκηνή, τραγουδούσαν και χόρευαν από πολύ μικρή ηλικία. Στη Λάρισα, παρουσία αξιωματικών, τον πυροβόλησαν την ώρα όπου βρισκόταν επί σκηνής και παιζόταν μια αντιβασιλική επιθεώρηση, την οποία μάλιστα είχε γράψει ο ίδιος. Έπειτα από τα δραματικά γεγονότα στη Θεσσαλία, η οικογένεια Παρίση ξεκίνησε περιοδεία σε ολόκληρη την Ελλάδα και ακολούθησε μια συγκλονιστική θεατρική περιπέτεια με σταθμούς την Κωνσταντινούπολη, τη Σερβία, την Ιταλία, την Αίγυπτο, τη Ρουμανία, το Παρίσι, τη Μασσαλία, τις Βρυξέλλες και την Αμερική. Οι περιοδείες του Παρίση διήρκεσαν δεκαετίες, προσφέροντας αποφασιστικά στις εστίες του ελληνισμού της διασποράς. Το ρεπερτόριο του θιάσου αποτελείτο από κωμωδίες, πολύπρακτες και μονόπρακτες, επιθεωρήσεις, οπερέτες, κωμειδύλλια, δραματικά ειδύλλια και πατριωτικά δράματα. Ο Παρίσης επιδίωκε να ικανοποιεί τα γούστα του κοινού, προσκολλημένος στα έργα της σίγουρης σκηνικής επιτυχίας, χαρίζοντας γενναιόδωρα άλλοτε γέλιο και άλλοτε συγκίνηση. Ο Αριστείδης Παρίσης υπήρξε πολυσχιδής προσωπικότητα και η δράση του εκτείνεται σχεδόν σε όλους τους κλάδους του θεάτρου: σκηνοθέτης, ηθοποιός, δάσκαλος θεάτρου, θεατρικός επιχειρηματίας, σκηνογράφος, ενδυματολόγος, συγγραφέας αλλά και μεταφραστής θεατρικών έργων.
Αντικείμενο του άρθρου αποτελεί η ιστορία και η διαδρομή των Επτανήσιων Γεράσιμου Κουρούκλη και Παναγή Σβορώνου, άγνωστων ή λιγότερο γνωστών καλλιτεχνών του μουσικού θεάτρου αλλά και της νεοελληνικής σκηνής του πρώτου μισού του 20ου αι. Γεννήθηκαν στην Κεφαλονιά στα τέλη του 19ου αι. και εν συνεχεία βρέθηκαν στην πρωτεύουσα όπου εντάχθηκαν σε αθηναϊκούς θιάσους παίζοντας μικρούς ρόλους, κυρίως σε επιθεωρήσεις και οπερέτες. Σύντομα ο Κουρούκλης εγκατέλειψε την Ελλάδα και περιπλανήθηκε σε όλο τον κόσμο (Αφρική, Αυστραλία, Αμερική κ.α.) αρχικά συμπράττοντας με περιοδεύονται θιάσους και αργότερα ως θιασάρχης, όπως και ο Σβορώνος, ο οποίος είχε μια αντίστοιχη περιπετειώδη καλλιτεχνική πορεία. Στις αρχές της δεκαετίας του 1930 οι δύο Κεφαλλονίτες κατάφεραν να γίνουν οι κυρίαρχοι των ελληνοαμερικανικών σκηνών της Αμερικής ως επικεφαλής οπερετικών θιάσων. Ο Κουρούκλης παρέμεινε στην Νέα Υόρκη, όπου έλαβε και την αμερικανική υπηκοότητα ενώ ο Σβορώνος επέστρεψε στην Ελλάδα, όπου όχι μόνο συνέχισε την θεατρική του πορεία αλλά δραστηριοποιήθηκε και στον κινηματογράφο. Οι δύο ηθοποιοί, έχουν πολλά κοινά σημεία επαφής, καθώς οι διαδρομές τους διασταυρώνονται στην Κεφαλονιά, σε αθηναϊκούς θιάσους, στην Αίγυπτο, στις αμερικανικές πολιτείες κ.α. δίνοντας μια ιδιότυπη συνοχή στην καλλιτεχνική τους πορεία.
Έλληνες μετανάστες στην Αμερική των αρχών του 20ου αι., όντας αυτοδίδακτοι, επιδόθηκαν στην συγγραφή αυτοσχέδιων θεατρικών έργων: κωμικών, ιστορικών, ηθικοπλαστικών αλλά κυρίως νοσταλγικών ή αλλιώς μεταναστευτικών δραμάτων. Οι δημιουργοί, αν και διαφορετικοί ως ιδιοσυγκρασίες, έχουν πολλά σημεία επαφής, καθώς εσωτερικές σχέσεις και διαδρομές διασταυρώνονται στις αμερικανικές πολιτείες δίνοντας μια ιδιότυπη συνοχή στην εργογραφία τους. Απ’ τη μια οι συνθήκες στέρησης και απ’ την άλλη η ανάγκη διατήρησης της ελληνικότητας τους οδήγησαν στη νοσταλγική δραματουργία. Το ύφος των έργων σε πολλά σημεία συγκλίνει διατηρώντας το ίδιο μοτίβο ως προς το σχήμα και το περιεχόμενο, ενώ ο αναγνώστης εύκολα αισθάνεται την αμηχανία συναισθηματολογίας και τον άκαιρο ρομαντισμό, την εσωστρέφεια και την αδυναμία προσαρμογής. Τα χρόνια που ακολούθησαν, όταν πλέον οι συνθήκες διαβίωσης των μεταναστών είχαν βελτιωθεί, παραμόνευε η παγίδα της επανάληψης, η μανιέρα. Η νέα γενιά δραματουργών της δεκαετίας του 30’, μετατοπίζουν την θεματολογία απομακρύνοντάς την από τις τραυματικές μεταναστευτικές εμπειρίες και εστιάζοντας στην ανάγκη απόκτησης μιας νέας ταυτότητας. Απ’ την μια λοιπόν διαιωνίζεται η νοσταλγική δραματουργία, «της μνήμης», από μερίδα παλαίμαχων δραματουργών και από την άλλη καλλιεργείται η γραφή της νέας εποχής, όπου συγκεράζει την ελληνική παράδοση με τον αμερικανικό τρόπο ζωής. Ωστόσο ούτε η νέα οπτική είναι ψύχραιμη αφού σχεδόν πάντα διαφαίνεται η ανοικτή πληγή της ξενιτιάς.
We measured a spin polarization above a Pt(111) surface in the vicinity of a Co nanostripe by spin-polarized scanning tunneling spectroscopy. The spin polarization exponentially decays away from the Pt-Co interface and is detectable at distances larger than 1 nm. By performing self-consistent ab initio calculations of the electronic structure for a related model system we reveal the interplay between the induced magnetic moments within the Pt surface and the spin-resolved electronic density of states above the surface.
By employing the layer-multiple-scattering method, properly extended to periodic assemblies of arbitrarily oriented axis-symmetric particles, we investigate the optical response of a three-dimensional spiral-staircase structure of metallic nanorods. We show that the combination of plasmonic modes and helical arrangement of the nanorods results in the formation of collective optical eigenmodes with a specific predominant circular polarization character, sizable polarization gaps, and negative group velocity bands that lead to negative refraction. Moreover, we demonstrate that multilayer slabs of the given crystal exhibit strong optical activity and circular dichroism combined with reduced dissipative losses, which make the proposed structure potentially useful for polarization control applications in miniaturized optoelectronic devices.

The possibility of Holocene subsidence along the northern coast of the Corinth Gulf is often mentioned in the literature; however, systematic detailed evidence that submergence (e.g. of archaeological remains) does not simply depend from eustatic sea-level rise is most often missing. In this paper, a new detailed study of submerged tidal-notch profiles along the limestone coast has shown that periods of sea-level stability are intercalated with periods of rapid subsidence or gradual relative sea-level rise. It appears that most of the sites considered, seem to have been affected by a relatively recent co-seismic subsidence of about half a meter, whereas during the longer period, by stages of relative sea-level stability and/or gradual relative sea-level rise. This evidence of subsidence is confirmed by radiocarbon dating in doline sediments, suggesting that during certain periods, a relative sea-level rise was much faster than the raising suggested by glacio-eustatic or hydro-isostatic estimations. Juxtaposing a list of known earthquakes occurred in the area shows that several earthquakes (e.g. the 1981 one for the easternmost sites considered) are potential candidates for the recent co-seismic displacements and thus supporting the geomorphological interpretations.
Objectives This study was undertaken to investigate the effect of d-alpha-tocopheryl polyethylene glycol 1000 succinate (vitamin E TPGS) on the dissolution of carbamazepine (CBZ) commercial tablets (Tegretol (R)) as a function of temperature and to modify the reaction-limited model of dissolution for the description of classical supersaturated dissolution data. Methods Solubility studies were performed using various concentrations of (i) TPGS and (ii) silicon dioxide and microcrystalline cellulose, which are excipients of Tegretol (R) at 10, 25 and 37 degrees C. Dissolution studies were carried out using Tegretol (R) tablets, 200 mg/tab. Key findings The solubility of CBZ in the presence of TPGS was found to increase in a concentration-dependent manner at all temperatures studied. Classical supersaturated dissolution curves with concentration maxima higher than the corresponding solubility values in the presence of TPGS were observed only at 10 degrees C. The model developed was based on a time-dependant expression for the forward microconstant of the CBZ-TPGS reaction at the solid-liquid interface and it was fitted successfully to the dissolution data of CBZ in the presence of TPGS at 10 degrees C. Conclusions Vitamin E TPGS increased the solubility of CBZ at all temperatures studied. The modification of the reaction-limited model of dissolution allowed us to describe classical supersaturated dissolution curves.
AIM: To investigate three isoforms of survivin in colorectal adenocarcinomas.
METHODS: We used the LightCycler Technology (Roche), along with a common forward primer and reverse primers specific for the splice variants and two common hybridization probes labeled with fluorescein and LightCycler-Red fluorophore (LC-Red 640). Real time quantitative polymerase chain reaction (PCR) was performed on cDNAs from 52 tumor specimens from colorectal cancer patients and 10 unrelated normal colorectal tissues. In the patients group, carcinoembryonic antigen (CEA) and CA19-9 tumor markers were also measured immunochemically.
RESULTS: Wild type survivin mRNA isoform was expressed in 48% of the 52 tumor samples, survivin-2b in 38% and survivin-ΔΕx3 in 29%, while no expression was found in normal tissues. The mRNA expression of wild type survivin presented a significant correlation with the expression of the ratio of survivin-2b, survivin-ΔΕx3, survivin-2b/wild type survivin and survivin-ΔΕx3/wild type survivin (P < 0.001). The mRNA expression of wild-survivin and survivin-ΔΕx3 was related with tumor size and invasion (P = 0.006 and P < 0.005, respectively). A significant difference was found between survivin-2b and morphologic cancer type. Also, the ratio of survivin-ΔEx3/wild-survivin was significantly associated with prognosis. No association was observed between the three isoforms and grade, metastasis, Dukes stage and gender. The three isoforms were not correlated with CEA and CA19-9.
CONCLUSION: Survivin isoforms may play a role in cell apoptosis and their quantification could provide information about clinical management of patients suffering from colorectal cancer.

Background and aims. Primary malignant peritoneal mesothelioma is a rare malignancy with an unfavorable prognosis. Pemetrexed has proven effective in the treatment of malignant mesothelioma, alone or in combination with platinum agents. In the present study, chemo-naïve patients were evaluated for the efficacy and safety of the pemetrexed-cisplatin combination. Methods. Six patients with diffuse peritoneal mesothelioma were treated with 6 cycles of pemetrexed (500 mg/m2) and cisplatin (75 mg/m2). Chemotherapy was administered on an outpatient basis every 3 weeks. Results. Complete response was observed in 2 patients (33%) and partial response was observed in 3 patients (50%). The estimated median overall survival was 24 months and the estimated median time to disease progression was 9.5 months. The regimen was well tolerated. Conclusions. Though our data reflect a small sample size, pemetrexed plus cisplatin accomplished a particularly high clinical benefit rate on chemo-naïve patients. Free full text available at www.tumorionline.it.
Global models of glacio-isostatic adjustment (GIA) depend critically on assumptions
about the rheology of the mantle and the history of ice melting since the Last
Glacial Maximum. Here we employ different viscosity profiles in the range of 0.4 x
10^21 Pa.s for upper mantle and 4 x 10^21Pa.s for lower mantle and several late-
Pleistocene ice sheets chronologies to interpret relative sea level (RSL) observations collected along the Tyrrhenian coasts. Neglecting the tectonic contributions to sea level variations and supposing a laterally uniform rheology, in these regions, RSL curves depart from eustasy mainly because of the effects of melt water loading, responsible for a widespread subsidence reaching its largest amplitude in the bulk of the basin. We reassess the importance of archaeological sea level indicators along the Tyrrhenian coasts of Italy (Lazio, Italy), recently revisited within the European COST Action ES0701. It appears that the local sea level rise since 2000 y ears ago can be estimated of the order of about half a meter, that agrees with the classical literature about this topic, rather than ~1.35 m, as recently proposed. The mismatch between observations from field data and model predictions can be partly attributed to the poor knowledge of the visco-elastic property of the mantle and to uncertainties of the details of the melting history. By forward modelling based on a modified ICE5G chronology, and using data from Tyrrhenian coast of Italy and SE Tunisia, we also evaluate the effects of a melt water pulse of the history of RSL, according to distinct assumptions about its origin
(Antarctic or Northern Hemispheric).
We analyse the spontaneous magnetization reversal of supported monatomic chains of finite length due to thermal fluctuations via atomistic spin-dynamics simulations. Our approach is based on the integration of the Landau-Lifshitz equation of motion of a classical spin Hamiltonian in the presence of stochastic forces. The associated magnetization lifetime is found to obey an Arrhenius law with an activation barrier equal to the domain wall energy in the chain. For chains longer than one domain wall width, the reversal is initiated by nucleation of a reversed magnetization domain primarily at the chain edge followed by a subsequent propagation of the domain wall to the other edge in a random-walk fashion. This results in a linear dependence of the lifetime on the chain length, if the magnetization correlation length is not exceeded. We studied chains of uniaxial and triaxial anisotropy and found that a triaxial anisotropy leads to a reduction of the magnetization lifetime due to a higher reversal attempt rate, even though the activation barrier is not changed.
Typical red–brown (Fe-rich) and high-quality white–grey (Fe-depleted) bauxite samples from active mines of the Parnassos-Ghiona area, central Greece, were investigated. According to \{XRF\} and ICP-MS analyses their actinide content, and particularly of Th, is relatively increased. Fe-depleted samples contain up to 62.75 ppm Th corresponding to 220 Bq/kg due to 228Ac (232Th-series), whereas Fe-rich samples are less Th-radioactive (up to 58.25 ppm Th, 180 Bq/kg due to 228Ac). Powder-XRD patterns showed that Th-enriched (Fe-depleted) bauxite consists mostly of diaspore (AlOOH polymorph), anatase and rutile (TiO2 polymorphs). SEM-EDS indicated the presence of Ti–Fe–containing phases (e.g. ilmenite, FeTiO3), chromite (Cr-spinel) and besides LREE-minerals (mostly bastnäsite/parisite-group) and zircon (ZrSiO4) hosting a part of the bulk Th. The presence of Th in diaspore and in Ti-containing phases (not detected by SEM-EDS as in the case of REE-minerals and zircon) was investigated, into distinct pisoliths of Fe-depleted bauxite, using μ-XRF and μ-XAFS in the SUL-X beamline of the \{ANKA\} Synchrotron facility (KIT, Germany). \{XAFS\} spectra of Th salts and Th-containing reference materials were obtained as well. Accordingly it was revealed, for the first time in the literature, that Ti-phases, and particularly anatase, host significant amounts of Th. This novel conclusion was complementary supported by LA-ICP-MS analyses indicated an average of 73 ppm Th in anatase grains together with abundant Nb (3356 ppm), Ta (247 ppm) and U (33 ppm). The Th LIII-edge \{XAFS\} spectra as compared to reference materials, give also evidence that Th4+ may not replace Ti4+ in distorted [TiO6] fundamental octahedral units of anatase and ilmenite lattice (CN = 6). The occupation of either extraframework sites of higher coordination (CN = 6.9 or even CN = 7.4), according to \{EXAFS\} signals evaluation, or of defected/vacant (**) sites is more probable. This is likely explained by the difficulty of Th4+ to replace directly Ti4+ in [6]-coordinated (octahedral) sites due to the large difference in the relevant ionic radii (0.940 and 0.605 Å respectively).
Background/Aim: Easily assessable clinical predictors of response to chemotherapy in advanced castration-resistant prostate cancer (CRPC) are few. The objective of this retrospective study was to search for and identify such candidate predictors of outcome. Patients and Methods: A retrospective analysis of clinical data of CRPC patients entered in the Clinical Therapeutics' departmental prostate cancer database from 1996-2009 was performed. Univariate and multivariate analyses for progression-free survival and overall survival included patients receiving both docetaxel- and non-docetaxel-containing regimens. Results: From 1996 until June 2009, 286 out of 313 patients in our database were treated with chemotherapy. Prostate-specific antigen (PSA) reduction >30% correlated with improved survival irrespective of treatment. Beyond previously reported predictors, i.e. baseline PSA>30 ng/dl, hemoglobin below 10 mg/dl, weight loss, poor performance status, elevated lactic dehydrogenase and alkaline phosphatase, and time to CRPC of less than or equal to two years was associated with a poor overall survival and shorter progression-free survival upon univariate analysis. Pain was associated with shorter survival. Multivariate analysis confirmed time to CRPC, lactate dehydrogenase and alkaline phosphatase as independent predictors of overall and progression-free survival. Conclusion: Time to castration resistance is an important predictor of outcome in CRPC. PSA reduction >30% predicts survival improvement following chemotherapy for CRPC regardless of chemotherapy applied.
Thromboembolic disease remains one of the most devastating and potentially lethal complications after elective total knee replacement (TKR) surgery. Studies have shown that 40-85% of patients undergoing TKR will develop venographically confirmed deep vein thrombosis (DVT) if they are not given any type of post-operative thromboprophylaxis and approximately 0.1 to 1.7% will suffer fatal pulmonary embolism (PE). Consequently, there is a general consensus that patients undergoing elective TKR require adequate antithrombotic prophylaxis. The following article reviews current evidence regarding chemical thromboprophylaxis after total knee replacement. Clinical guidelines as described by the American Academy of Orthopaedic Surgeons (AAOS), the American College of Chest Physicians (ACCP) and the UK's National Institute for Health and Clinical Excellence (NICE) are summarized along with the differences between the recommendations. The results of the new oral anticoagulants are reviewed as well as the most recent developments in the search for the most effective venous thromboembolism (VTE) prophylaxis after TKR surgery.
INTRODUCTION: The dilemma of extraction vs nonextraction treatment, along with the uncertain potential of orthodontic treatment to control vertical dimensions, still remains among the most controversial issues in orthodontics. The aim of this study was to evaluate 2 contradictory treatment protocols for hyperdivergent Class II Division 1 malocclusion regarding their effectiveness in controlling vertical dimensions.
METHODS: The subjects were retrospectively selected from 2 orthodontic offices that used contrasting treatment protocols. The patients had similar hyperdivergent skeletal patterns, malocclusion patterns, skeletal ages, and sexes. Group A (29 patients) was treated with 4 first premolar extractions and "intrusive" mechanics (eg, high-pull headgear), whereas group B (28 patients) was treated nonextraction with no regard to vertical control (eg, cervical headgear, Class II elastics). Twenty-seven landmarks were digitized on lateral cephalometric radiographs before and after treatment, and 14 measurements were assessed. Geometric morphometric methods were also implemented to evaluate size and shape differences.
RESULTS: As expected, the maxillary and mandibular molars translated mesially and the mandibular incisors uprighted in group A but remained approximately unchanged in group B. The vertical positions of the molars and the incisors were similar between groups before and after treatment, although they were altered by treatment or growth. No significant differences were observed in the posttreatment skeletal measurements between the 2 groups, including vertical variables, which remained unaltered. Permutation tests on Procrustes distances between skeletal shapes confirmed these results.
CONCLUSIONS: This study demonstrated the limitations of conventional orthodontics to significantly alter skeletal vertical dimensions. More important factors are probably responsible for the development and establishment of the vertical skeletal pattern, such as neuromuscular balance and function.
The aim of this study was to compare craniofacial morphology and soft tissue profiles in patients with complete bilateral cleft lip and palate at 9 years of age, treated in two European cleft centres with delayed hard palate closure but different treatment protocols. The cephalometric data of 83 consecutively treated patients were compared (Gothenburg, N=44; Nijmegen, N=39). In total, 18 hard tissue and 10 soft tissue landmarks were digitized by one operator. To determine the intra-observer reliability 20 cephalograms were digitized twice with a monthly interval. Paired t-test, Pearson correlation coefficients and multiple regression models were applied for statistical analysis. Hard and soft tissue data were superimposed using the Generalized Procrustes Analysis. In Nijmegen, the maxilla was protrusive for hard and soft tissue values (P=0.001, P=0.030, respectively) and the maxillary incisors were retroclined (P<0.001), influencing the nasolabial angle, which was increased in comparison with Gothenburg (P=0.004). In conclusion, both centres showed a favourable craniofacial form at 9-10 years of age, although there were significant differences in the maxillary prominence, the incisor inclination and soft tissue cephalometric values. Follow-up of these patients until facial growth has ceased, may elucidate components for outcome improvement.
Comparable international data on food and nutrient intake is often hindered by the lack of a common instrument to assess food intake. The objective of this study was within the Global Allergy and Asthma European Network of Excellence (GA(2)LEN), we developed and piloted a food frequency questionnaire (FFQ) to assess its validity in Europe.|Five countries participating in GA(2)LEN took part in the pilot study. A total of 200 adults aged 31-75 years were invited to complete a FFQ in two occasions and to give a blood sample. The intra-class correlation coefficient (ICC) was used to assess repeatability of the FFQ. Plasma phospholipid fatty acids (FAs) were analysed by gas chromatography. Pearson correlation was used to analyse the correlation between estimated dietary FA intake and plasma phospholipid FA levels.|A total of 177 participants (89%) had complete data on FFQ(1) and plasma phospholipid FAs. In all, 152 participants (76%) completed both FFQs. ICCs between macronutrients ranged from 0.70 (saturated FAs) to 0.78 (proteins) and between 0.70 (retinol) and 0.81 (vitamin D) for micronutrients. Dietary n-3 FAs showed a good correlation with total plasma phospholipid n-3 FAs and with docosahexaenoic acid in the whole sample (0.40) and in individual countries. Poor correlations were observed for other FAs.|The GA(2)LEN FFQ is an appropriate tool to estimate dietary intake for a range of nutrients across Europe regardless of cultural and linguistic differences. The FFQ seems to be useful to estimate the intake of n-3 FAs but not other FAs.
OBJECTIVES: To investigate the hypothesis that specific fracture patterns in patients with femoral shaft fractures can predict the likelihood of associated injuries.
DESIGN: Retrospective cohort study.
SETTING: Level I trauma center.
PATIENTS/PARTICIPANTS: Consecutive patients treated because of a traumatic diaphyseal femoral fracture.
MAIN OUTCOME MEASUREMENT: We studied the association between the Orthopaedic Trauma Association (OTA) fracture classification (derived from initial radiographs) and concomitant injuries of the head, spine, chest, abdomen, and pelvis with a severity of two or more points according to the Abbreviated Injury Scale by logistic regression analysis.
RESULTS: One hundred forty-three of 203 patients (80 men, 63 women; mean age 54 ± 26 years) met the inclusion criteria. All patients had unilateral diaphyseal fractures, 64 OTA 32.A (45%), 46 OTA 32.B (32%), and 33 OTA 32.C (23%). In addition, 134 associated injuries were identified in 52 patients. Increasing fracture severity, as expressed by the OTA classification (ie, A, B, C), was significantly associated with a higher likelihood of thoracic (odds ratio [OR], 5.89; 95% confidence interval [CI], 2.59-13.40), pelvic (OR, 4.55; 95% CI, 2.01-10.28), upper (OR, 2.38; 95% CI, 1.27-4.48), and lower extremity injuries (OR, 3.12; 95% CI, 1.78-5.46). Fracture severity explained between 70% and 86% of the probability of having accompanying injuries.
CONCLUSION: Radiographic grading of the severity of a femoral shaft fracture may signal the presence of accompanying injuries and should contribute to the clinical decision-making process in severe trauma.

This study explores the longitudinal relationship between patient characteristics and use of 4 drug classes (antihypertensives, antidepressants, antipsychotics, and hormones) that showed significant changes in use rates over time in patients with Alzheimer disease. Patient/caregiver-reported prescription medication usage was categorized by drug class for 201 patients from the Predictors Study. Patient characteristics included use of cholinesterase inhibitors and/or memantine, function, cognition, living situation, baseline age, and sex. Assessment interval, year of study entry, and site were controlled for. Before adjusting for covariates, useage increased for antihypertensives (47.8% to 62.2%), antipsychotics (3.5% to 27.0%), and antidepressants (32.3% to 40.5%); use of hormones decreased (19.4% to 5.4%). After controlling for patient characteristics, effects of time on the use of antidepressants were no longer significant. Antihypertensive use was associated with poorer functioning, concurrent use of memantine, and older age. Antipsychotic use was associated with poorer functioning and poorer cognition. Antidepressant use was associated with younger age, poorer functioning, and concurrent use of cholinesterase inhibitors and memantine. Hormone use was associated with being female and younger age. Findings suggest accurate modeling of the Alzheimer disease treatment paradigm for certain subgroups of patients should include antihypertensives and antipsychotics in addition to cholinesterase inhibitors and memantine.
A major part of the burden of asthma is caused by acute exacerbations. Exacerbations have been strongly and consistently associated with respiratory infections. Respiratory viruses and bacteria are therefore possible treatment targets. To have a reasonable estimate of the burden of disease induced by such infectious agents on asthmatic patients, it is necessary to understand their nature and be able to identify them in clinical samples by employing accurate and sensitive methodologies. This systematic review summarizes current knowledge and developments in infection epidemiology of acute asthma in children and adults, describing the known impact for each individual agent and highlighting knowledge gaps. Among infectious agents, human rhinoviruses are the most prevalent in regard to asthma exacerbations. The newly identified type-C rhinoviruses may prove to be particularly relevant. Respiratory syncytial virus and metapneumovirus are important in infants, while influenza viruses seem to induce severe exacerbations mostly in adults. Other agents are relatively less or not clearly associated. Mycoplasma and Chlamydophila pneumoniae seem to be involved more with asthma persistence rather than with disease exacerbations. Recent data suggest that common bacteria may also be involved, but this should be confirmed. Although current information is considerable, improvements in detection methodologies, as well as the wide variation in respect to location, time and populations, underline the need for additional studies that should also take into account interacting factors.
In 2 quasi-experimental field studies in a real-life physical education (PE) setting, the authors investigated whether the interest-enjoyment and vitality of Greek pupils (age range, 10-12 years) varied from class-to-class as a function of the class-to-class variation in the manipulated motivational environment (Studies 1 and 2) and pupils' relative autonomous motivation (Study 2). In Study 1, multilevel analyses showed at the within-student level that students (N = 138, 48.6% boys and 51.4% girls) reported, on average, more interest-enjoyment and vitality after a need-supportive, relative to a typical (i.e., control group), PE class. This main effect was replicated in Study 2 (N = 155, 53.6% boys and 46.4% girls), and Study 2 findings further showed at the between-student level that interest-enjoyment was somewhat higher among pupils scoring higher in relative autonomous motivation. Moreover, Study 2 provided evidence for an interaction effect such that pupils with high, as compared with those with low, relative autonomous motivation benefited significantly more from a need-supportive class. Perceived need support was found to fully explain the effects of manipulated need support on interest-enjoyment and vitality. Results are discussed within the self-determination theory (Deci & Ryan, 2000).
The largest Local Group spiral galaxy, M31, has been completely imaged for the first time, obtaining a luminosity lower limit about 1035erg/s in the 0.2-4.5keV band. Our XMM-Newton EPIC survey combines archival observations along the major axis, from June 2000 to July 2004, with observations taken between June 2006 and February 2008 that cover the remainder of the D25 ellipse. The main goal of the paper is to study X-ray source populations of M31. An X-ray catalogue of 1897(*) sources was created with 914 detected for the first time. Source classification and identification were based on X-ray hardness ratios, spatial extent of the sources, and cross correlation with catalogues in the X-ray, optical, infrared and radio wavelengths. We also analysed the long-term variability of the X-ray sources and this variability allows us to distinguish between X-ray binaries and active galactic nuclei (AGN). Furthermore, supernova remnant classifications of previous studies that did not use long-term variability as a classification criterion could be validated. Including previous Chandra and ROSAT observations in the long-term variability study allowed us to detect additional transient or at least highly variable sources, which are good candidate X-ray binaries. (*) the final catalog of table5 icludes 1948 sources. (2 data files).
Context. Classical novae (CNe) represent the major class of supersoft X-ray sources (SSSs) in the central region of the galaxy M31. We performed a dedicated monitoring of the M31 central region with XMM-Newton and Chandra between Nov 2007 and Feb 2008 and between Nov 2008 and Feb 2009, respectively, to find SSS counterparts of CNe, determine the duration of their SSS phase, and derive physical outburst parameters. We systematically searched our data for X-ray counterparts of CNe, determined their X-ray light curves and characterised their spectra using blackbody fits and white dwarf (WD) atmosphere models. Additionally, we determined luminosity upper limits for all previously known X-ray emitting novae that are not detected any more and for all CNe in our field of view with optical outbursts between one year before the start of the X-ray monitoring (Oct 2006) and its end (Feb 2009). (2 data files).
BACKGROUND: Osteonecrosis has been associated with the presence of white matter lesions. The objective of this study was to investigate the association between macro- and micro- vascular disease and white matter lesions.
METHODS: Sixty-four patients with femoral head osteonecrosis were assessed during a cross sectional study in our university-based hospital. A vascular 'profile' was obtained for each patient and included measurement of plasma lipids, fundoscopic examination and common carotid artery triplex ultrasonography. All patients had brain MRI to assess for presence of white matter lesions. The two groups formed, with and without white matter lesions, were compared in order to define the association between white matter lesions and vascular disease.
RESULTS: Patients without white matter lesions had more frequently corticosteroid induced osteonecrosis. There was no difference in the two groups with respect to intima media thickness and ApoB/ApoA1 ratio. Only one of our patients demonstrated retinopathy.
CONCLUSIONS: There is no evidence of concurrent macro- and micro- vascular pathology in young patients with white matter lesions and femoral head osteonecrosis. Cortisone appears to have a 'protective' effect against occurrence of white matter lesions.
This paper explores the role of meso- and macro-context in the interpretation of text, on the basis of our research on the text of Greek laws. The use of the grammatical categories of tense, aspect and modality in these texts deviates from everyday use (Panaretou 2005, Moser and Panaretou 2009).The study is based on a comparison of native speakers’ judgements (elicited through questionnaires and interviews and subjected to qualitative analysis) on law texts and everyday contexts containing the performance of the same type of speech act as the law: a mother setting a rule for her children and delineating the consequences of breaking this rule. Uses judged unanimously as ungram- matical and unacceptable in the latter context went unnoticed in law texts.Our conclusion is that what licenses deviant uses is not the type of speech act, but the genre of law texts; it is argued that, as a form of meso-context, the genre of law texts, by virtue of being highly institutionalized within the cognitive and socio-cultural context in which it is embedded (Fetzer 2004, 2007), creates a cognitive frame so powerful as to impose specific interpretations even to grammatical forms which would be unacceptable in different (con)texts.
Aims: One of the goals of the XMM-Newton survey of the Small Magellanic Cloud is to study the Be/X-ray binary population. During one of our first survey observations, a bright new transient - XMMU J004814.0-732204 - was discovered. Methods: We present the analysis of the EPIC X-ray data, together with optical observations, to investigate the spectral and temporal characteristics of XMMU J004814.0-732204. Results: We found coherent X-ray pulsations in the EPIC data with a period of (11.86642 ± 0.00017) s. The X-ray spectrum can be modelled by an absorbed power law with an indication for a soft excess. Depending on the modelling of the soft X-ray spectrum, the photon index ranges between 0.53 and 0.66. We identify the optical counterpart as a B = 14.9 mag star that was monitored during the MACHO and OGLE-III projects. The optical light curves show regular outbursts by ~0.5 mag in B and R and up to 0.9 mag in I, which repeat on a time scale of about 1000 days. The OGLE-III optical colours of the star are consistent with an early B spectral type. An optical spectrum obtained at the 1.9 m telescope of the South African Astronomical Observatory in December 2009 shows Hα emission with an equivalent width of 3.5 ± 0.6 Å. Conclusions: The X-ray spectrum and the detection of pulsations suggest that XMMU J004814.0-732204is a new high-mass X-ray binary pulsar in the SMC. The long term variability and the Hα emission line in the spectrum of the optical counterpart identify it as a Be/X-ray binary system.
Context. Classical novae (CNe) represent the major class of supersoft X-ray sources (SSSs) in the central region of the galaxy M 31. Aims: We performed a dedicated monitoring of the M 31 central region with XMM-Newton and Chandra between Nov. 2007 and Feb. 2008 and between Nov. 2008 and Feb. 2009, respectively, to find SSS counterparts of CNe, determine the duration of their SSS phase, and derive physical outburst parameters. Methods: We systematically searched our data for X-ray counterparts of CNe, determined their X-ray light curves and characterised their spectra using blackbody fits and white dwarf (WD) atmosphere models. Additionally, we determined luminosity upper limits for all previously known X-ray emitting novae that are not detected any more and for all CNe in our field of view with optical outbursts between one year before the start of the X-ray monitoring (Oct. 2006) and its end (Feb. 2009). Results: We detected 17 X-ray counterparts of CNe in M 31, only four of which were previously known. These latter sources are still active 12.5, 11.0, 7.4 and 4.8 years after the optical outburst. In addition, we detected three known SSSs without a nova counterpart. Four novae displayed short SSS phases (<100 d). Based on these results and previous studies we compiled a catalogue of all novae with SSS counterparts in M 31 known so far. We used this catalogue to derive correlations between the following X-ray and optical nova parameters: turn-on time, turn-off time, blackbody temperature (X-ray), t2 decay time and expansion velocity of the ejected envelope (optical). Temperatures derived from blackbody fits and WD atmosphere models were found to characterise the effective SSS temperatures almost equally well. Furthermore, we found a first hint for the existence of a difference between SSS parameters of novae associated with the stellar populations of the M 31 bulge and disk. Additionally, we conducted a Monte Carlo Markov chain simulation on the intrinsic fraction of novae with SSS phase. This simulation showed that the high fraction of novae without detected SSS emission might be explained by the inevitably incomplete coverage with X-ray observations in combination with a large part of novae with short SSS states, as expected from the WD mass distribution. Conclusions: Our results confirm that novae are the major class of SSSs in the central region of M 31. The catalogue of novae with X-ray counterpart, mainly based on our X-ray monitoring, contains valuable insight into the physics of the nova process. In order to verify our results with an increased sample, more monitoring observations are needed.

Aims: We study the expected variability patterns of blazars within the two-zone acceleration model, putting special emphasis on flare shapes and spectral lags. Methods: We semi-analytically solve the kinetic equations that describe the particle evolution in the acceleration and radiation zone. We then perturb the solutions by introducing Lorentzian variations in its key parameters and examine the flaring behavior of the system. We apply the above to the X-ray observations of blazar 1ES 1218+304, which exhibited a hard lag behavior during a flaring episode and discuss possibilities of producing it within the context of our model. Results: The steady-state radio to X-rays emission of 1ES 1218+304 can be reproduced with parameters that lie well within the ones generally accepted from blazar modeling. Additionally, we find that the best way to explain its flaring behavior is by varying the rate of particles injected in the acceleration zone.
In this essay, we study the relationship between psychoanalysis and education, a relationship that is as old as the history of psychoanalysis itself. Freud’s views on this issue, which appear scattered in his various writings, are identified and synthesized. More specifically, we discuss Freud’s views on the importance of applying psychoanalysis in education, the significance of the educator’s personality, his/her difficulties in understanding children, the “prophylactic” (preventive) role of education, the necessity to adopt an optimum stance between the two poles of permissiveness and frustration, the links of education with sublimation and culture, the limits of education as compared to the individual’s development, etc. These views are discussed in relation to Anna Freud’s systematic elaboration on the relationship between psychoanalysis and education, as well as to various views of contemporary psychoanalysts on the same issue.
In this theoretical paper, we search and integrate historical information about Sigmund Freud’s, the founder of psychoanalysis, attendance of the classic Gymnasium in Vienna (1865‐1873). Drawing from Freud’s essay “Some reflections on schoolboy psychology” (1914), which he wrote for the fiftieth anniversary of his school, some of his letters, his biographer Ernest Jones, as well as the testimony of one of his sisters and the son of one of his classmates, we attempt to reconstruct Freud’s attendance in the Gymnasium. We also attempt a historical interpretation of psychoanalysis, according to which Freud’s years in the classic Gymnasium – mainly his relationships with his masters – are associated with the Oedipus complex, ambivalence, and of course the educational philosophy of that time.
Η απόφαση 2533/2011 του Δ Τμήματος του ΣτΕ παραπέμπει το ζήτημα της συνταγματικότητας της θέσπισης πληθυσμιακών κριτηρίων για την έκδοση άδειας λειτουργίας φαρμακείου στην Ολομέλεια. Η απόφαση ΣτΕ (Ολ.) 3665/2005 είχε κρίνει ότι τα πληθυσμιακά κριτήρια αντίκεινται στο άρθρο 5 παρ. 1 του Συντάγματος που καθιερώνει την επαγγελματική ελευθερία. Από την ανάγνωση των αποφάσεων αυτών δεν προκύπτει κανένα νεότερο νομικό στοιχείο. Υποστηρίζω ότι τα πληθυσμιακά κριτήρια όπως ισχύουν δεν συνάδουν ούτε με το άρθρο 5 παρ. 1 του Συντάγματος ούτε με όσα το ευρωπαϊκό δίκαιο κάνει δεκτά. Δεν αποτελεί λόγο δημοσίου συμφέροντος η εξασφάλιση της βιωσιμότητας των υφιστάμενων φαρμακείων ενώ η πρόσβαση του πληθυσμού της υπαίθρου στο φάρμακο μπορεί να επιτευχθεί με προσφορότερα και λιγότερο περιοριστικά μέτρα.
Στόχος της εργασίας αυτής είναι να συνοψίσει και να παρουσιάσει τα ευρήματα των πιο πρόσφατων μετα-αναλύσεων και ανασκοπήσεων για την αποτελεσματικότητα των προληπτικών και παρεμβατικών προγραμμάτων κατά του σχολικού εκφοβισμού. Γίνονται αναφορές στα ερευνητικά σχέδια με τα οποία έχει αξιολογηθεί η αποτελεσματικότητα των προγραμμάτων, καθώς και στους τρόπους αξιολόγησης του εκφοβισμού και της θυματοποίησης στα προγράμματα αυτά. Με δεδομένη την ελάχιστη έως μέτρια επιτυχία των περισσότερων παρεμβάσεων, διατυπώνονται ερμηνείες για την περιορισμένη αυτή αποτελεσματικότητα. Η ερευνητικά τεκμηριωμένη γνώση των αρχών, των συστατικών και των επιπέδων παρέμβασης που επιφέρουν τη μεγαλύτερη μείωση του σχολικού εκφοβισμού είναι απολύτως απαραίτητη για τη διαμόρφωση της αντι-εκφοβιστικής πολιτικής και στην Ελλάδα.

The aim of my participation in the Round Table entitled “Victimization and bullying in school (kindergarten, primary school, secondary school)” is to present a number of dysfunctional beliefs of educators about school bullying, which impede the implementation of preventive and interventive anti-bullying programs. Data are drawn from empirical research in various countries, and from recent Greek studies. Identifying and challenging these dysfunctional beliefs is a necessary first step before anti-bullying intervention, as it is well documented that the effectiveness of this intervention depends largely on the educator.
Η άποψη των φοιτητών/τριών ΤΕΦΑΑ Αθηνών σχετικά με την πρόθεση χρήσης αναβολικών ουσιών στον αθλητισμό,Παναγιώτης Μαυροδάκος, Κωνσταντίνα Γογγάκη. Είναι βέβαιο, ότι η χρήση απαγορευμένων ουσιών υποκρύπτει πολλά κοινωνικά προβλήματα. Ο αθλητισμός, ιδιαίτερα όταν λαμβάνει χώρα σε μια υλιστική κοινωνία που έχει καταστήσει ως προτεραιότητά της την οικονομική επιτυχία, καλείται να ανταποκριθεί σε παρόμοιο ρόλο. Εξάλλου, τα μέσα μαζικής ενημέρωσης διογκώνουν πολλές φορές υπέρμετρα την οικονομική διάσταση μιας επιλογής, προβάλλοντας συχνά κάθε περίπτωση τέτοιας επιτυχίας. Τα ίδια εστιάζονται με ζήλο, τόσο σε περιπτώσεις προσώπων οικονομικής επιφάνειας, όσο και σε πρόσωπα του επαγγελματικού αθλητισμού. Ακόμη χειρότερα, σπεύδουν να προβάλλουν πολύ πέρα από το δέον περιπτώσεις αθλητών και πρωταθλητών που έχουν κάνει χρήση απαγορευμένων ουσιών, με αποτέλεσμα να έχει εθιστεί το μεγαλύτερο μέρος της κοινωνίας, στην αποδοχή τέτοιου είδους ενεργειών. Το αθλητικό μάρκετινγκ, εξάλλου, τείνει να πείσει ολόκληρη την κοινωνία, ότι η χρήση ναρκωτικών και αναβολικών ουσιών είναι απαραίτητη για την επίτευξη οποιασδήποτε επιτυχίας, κάτι, όμως, το οποίο πλάθει μια χαλαρή ηθική συνείδηση. Όσο, όμως κι αν ευθύνονται στη χρήση των αναβολικών ουσιών τα μέσα μαζικής ενημέρωσης και το αθλητικό μάρκετινγκ, δεν μπορεί ν’ αποσείσει κανείς την κύρια ευθύνη από την ίδια την κοινωνία και τις διαμορφωμένες αξίες της. Εάν οι αξίες αυτές δεν είναι ικανές να θωρακίσουν το άτομο με άμυνες και αντιστάσεις, τότε η ηθική του υπόσταση είναι διάτρητη, επιτρέποντας την είσοδο πολλών παράσιτων. Τα παράσιτα που ως ‘απαγορευμένες ουσίες’ εισχωρούν στο σώμα του αθλητισμού, μπορεί κατά καιρούς να του προσφέρουν μια ψεύτικη χαρά, αλλά σταδιακά το κατατρώνε. Οι ουσίες αυτές διατίθενται σε μεγάλη γκάμα, που εκτείνεται από τα ορμονικά πεπτίδια και τα ανάλογά τους, τα διεγερτικά, τα ναρκωτικά διεγερτικά, τους β-αναστολείς, τα διουρητικά, τα ανδρογόνα αναβολικά στεροειδή και τις απαγορευμένες μεθόδους. Η ποικιλία τους έχει ξεπεράσει προ πολλού την όποια «ερασιτεχνικού τύπου» παραγωγή, έχοντας φτάσει σε σφαίρες ψυχρού επαγγελματισμού και αισχροκέρδειας. Ακόμη και από τα Γυμναστήρια της γειτονιάς οι νέοι προμηθεύονται ανεξέλεγκτης παραγωγής ουσίες, προκειμένου να «φουσκώσουν» τους μύες τους.

Σκοπός αυτής της έρευνας ήταν να εξετάσει το κλίμα της σχολικής τάξης όπως το αντιλαμβάνονται τα παιδιά που έχουν προβλήματα συμπεριφοράς. Η συμβολή της έρευνας είναι ότι συμπεριέλαβε μια μεγάλη ποικιλία διαστάσεων του κλίματος της σχολικής τάξης και μια μεγάλη ποικιλία προβλημάτων συμπεριφοράς. Σε 221 μαθητές Ε΄ και Στ΄ τάξης από σχολεία της Αθήνας δόθηκε το Ερωτηματολόγιο της Ζωής στη Σχολική Τάξη (Johnson & Johnson, 1983). Από αυτούς, 46 μαθητές παρουσίαζαν προβλήματα συμπεριφοράς, σύμφωνα με το Achenbach Ερωτηματολόγιο για Εκπαιδευτικούς (Achenbach & Rescorla, 2001) και συγκρίθηκαν, ως προς το αντιληπτό κλίμα της σχολικής τάξης, με 50 μαθητές ίδιας ηλικίας και φύλου χωρίς προβλήματα συμπεριφοράς. Τα ευρήματα έδειξαν ότι οι μαθητές με προβλήματα συμπεριφοράς είχαν χαμηλότερη σχολική αυτοεκτίμηση, την τάση να βιώνουν αποξένωση, να έχουν εξωγενές κίνητρο και να βιώνουν ανταγωνισμό περισσότερο από τους συμμαθητές τους χωρίς προβλήματα συμπεριφοράς. Για κάθε σύνδρομο προβλημάτων συμπεριφοράς προέκυψαν διαφορετικές συνδέσεις με τη σχολική προσαρμογή και το αντιληπτό κλίμα της σχολικής τάξης. Συζητούνται και οι εκπαιδευτικές υποδηλώσεις των ευρημάτων.
The moral evaluation of the use of illegal substances according to The students of the Sport Physical Education Department of the University of Athens.Panagiotis Mavrodakos, Konstantina Goggaki, and Polydoropoulos Konstantinos.
In modern Olympic Games, the first substances used as reinforcement of the athlete for the coveted performance were heroin in racing and morphine on fights. Since then, there is a long history of doping in sport. In competitive sports, where main objective is the maximum athletic performance and, at all costs victory, growing number of athletes recourse to doping for strengthening capabilities, supplanting both moral inhibitions and the effects of this selection in their natural health and life achievements. This study just shows the moral evaluation of the use of illicit substances through the students 'views in the Sport Physical Education Department of the University of Athens. Students' views were recorded on a questionnaire. Their view is particularly important because of its modern and their future position in sport and education. The sample consisted of 200 students in Sport Physical Education Department of Athens, randomly selected. According to the survey results, the majority of the surveyed population had been suffering from the phenomenon of doping in sport. Men, in a small percentage, it seems to have more relaxed moral conscience regarding the use of doping substances by women. This may be due to the fact that in this sample, the men who are engaged to a greater extent with the high level championship.

(2011). H μεταστροφή του Αχιλλέα στα ‘επί Πατρόκλω άθλα’ της ραψωδίας Ψ της Ιλιάδος. Ο βαθύτατος πόνος ως αφορμή για αναδιαμόρφωση της προσωπικότητας του ανθρώπου Κωνσταντίνα Γογγάκη, Ελισάβετ Στραβάκου
Στους αγώνες προς τιμήν του Πατρόκλου, τους επικήδειους αγώνες της ραψωδίας Ψ της Ιλιάδος οι οποίοι διεξάγονται ενώ το δέμας του νεκρού είναι ακόμη ζεστό (Γογγάκη, 2003), ο Αχιλλέας και οι άλλοι Έλληνες επιδεικνύουν την πιο πολιτισμένη συμπεριφορά τους. Ειδικότερα ο Αχιλλέας μετά το θάνατο του Πατρόκλου εξωτερικεύει το μεγάλο του πόνο και το θυμό του με ακραίες αντιδράσεις, μη μπορώντας να αποδεχθεί τον ξαφνικό και άδικο χαμό του αγαπημένου του συντρόφου. Το ξέσπασμα αυτό λειτουργεί λυτρωτικά για τον ήρωα, ώστε να εισέλθει στη φάση της συνειδητοποίησης του θανάτου, ξαναβρίσκοντας και τα ευγενικά χαρακτηριστικά του. Ο Αχιλλέας εξέρχεται από την οδυνηρή εμπειρία του θανάτου περισσότερο «εξανθρωπισμένος» από πριν, με νέα ποιοτικά δεδομένα στην προσωπικότητά του (Krook, 1969). Ο απαρηγόρητος και γεμάτος μίσος ήρωας των προηγούμενων ραψωδιών μεταστρέφεται σε έναν σπλαχνικό ήρωα, ο οποίος δείχνει μια ελεγχόμενη και κάπως απόμακρη κοινωνικότητα (Whitman, 1958, Edwards, 2001).
Στην κατάληξη των επικήδειων αγώνων ο Αχιλλέας είναι ο πιο αγνώριστος απ’ όλους. Ο ήρωας αυτός, με σταθερό γνώρισμά του ως τώρα την αδιαλλαξία, γίνεται στην ενότητα αυτή ο διαλλακτικότερος όλων, ακτινοβολώντας τέτοια καλοσύνη που χαρακτηρίζει τους υψηλόφρονες (Scadewaldt, 1982) . Αξίζει να επισημανθεί ότι στους αθλητικούς αυτούς αγώνες ο απαρηγόρητος για τον θάνατο του Πατρόκλου χαμογελάει, για πρώτη και μοναδική φορά σε ολόκληρη την Ιλιάδα (Ψ 155-157). Ο Αχιλλέας χαμογελάει γνωρίζοντας ότι το αγώνισμα της αρματοδρομίας όσο διαρκεί αναστέλλει και απωθεί το θανάσιμο βάρος του πολέμου. Η ραψωδία Ψ της Ιλιάδος αποτελεί, εν προκειμένω, τη ραψωδία της ψυχικής μεταστροφής. Ο πόνος που επιφέρει στην ανθρώπινη ψυχή ο θάνατος ενός αγαπημένου προσώπου είναι οξύτατος, και η εμπειρία αυτή προξενεί βαθύ ρήγμα στην προσωπικότητα του ανθρώπου, ενώ στη συνέχεια ο πόνος αυτός αρχίζει να μεταστρέφεται σε εμπειρία ζωής και σε γνώση. Η οδύνη της απώλειας σταδιακά ενισχύει την επίγνωση σχετικά με τον φθαρτό χαρακτήρα του ανθρώπινου βίου. Κάποια στιγμή θάρθει και η σειρά του ζωντανού να ακολουθήσει την αναπόδραστη πορεία. Η συνείδηση αυτή τον κάνει πιο ανθρώπινο, διαμορφώνοντας, εν τέλει, μέσα από τη διαδικασία του πόνου, τη νέα ποιότητά του.

Εισαγωγή. Στηv Πετοσφαίριση είναι απαραίτητο από πλευράς τεχνικής και τακτικής να γνωρίζουμε ποιες τεχνικές δεξιότητες επηρεάζουν την απόδοση (Eom & Schutz, 1992). Ειδικά στα σετ με μικρή διαφορά πόντων μεταξύ των αντιπάλων ομάδων ανδρών υψηλού επιπέδου η επίθεση είναι η σημαντικότερη τεχνική δεξιότητα (Drikos & Vagenas, 2011). Η παρούσα έρευνα αξιολόγησε τις διαφορές επίδρασης βασικών δεξιοτήτων συγκρίνοντας την αγωνιστική απόδοση νικητριών και ηττημένων ομάδων σε όλους τους τύπους των σετ. Μέθοδος. Τα δεδομένα προήλθαν από 175 σετ του Πανευρωπαϊκού Πρωταθλήματος Ανδρών (2009). Αναλύθηκαν 12 δείκτες απόδοσης (%) από τέσσερις δεξιότητες: επίθεση, σερβίς, υποδοχή, μπλοκ. Η ανάλυση cluster εξήγαγε τρεις τύπους σετ (διαφορά): αμφίρροπα (2 πόντοι), ισορροπημένα (3-5 πόντοι), άνισα (>5 πόντοι). Λόγω των ακραίων κατανομικών λοξοτήτων σε 11 από τις 12 μεταβλητές (K-S, p<0,05) η στατιστική ανάλυση έγινε με τoν απαραμετρκό έλεγχο σύγκρισης διάμεσων τιμών (Wilcoxon) Αποτελέσματα. Οι έλεγχοι Wilcoxon έδειξαν ότι 9 δείκτες βγήκαν σημαντικοί (p<0,05) για όλα το σύνολο των δεδομένων και για τα άνισα σετ, 6 δείκτες για τα ισορροπημένα σετ και ένας δείκτης για τα αμφίρροπα σετ. Οι νικήτριες ομάδες είχαν σημαντικά μεγαλύτερο ποσοστό άμεσων πόντων από την επίθεση από ότι οι ηττημένες (p<0,001). Συμπεράσματα. Επιβεβαιώνεται η προπονητική προτεραιότητα ανάπτυξης των επιθετικών ικανοτήτων των αθλητών ανδρικών ομάδων υψηλού επιπέδου .
(2011). Doping as a major problem in modern sport and the views of the Sport Physical Education Department of the University of Athens students.
Polydoropoulos Konstantinos, Konstantina Goggaki, and Panagiotis Mavrodakos.
The championship has now become professional and high ideals sometimes replaced by an effort to maximize profit. Throughout the world, doping is an illegal act, which is treated with sentences. However, the problem, can not be limited to repression and criminalization of doping, but mainly on prevention. This study presents the students’ views in relation to doping in modern sport. Their view seems to be of great value as they are in majority, modern athletes and future physical education teachers, both in education and in training sessions clubs. Students' views recorded through questionnaire. The results appear to be quite encouraging as only a small percentage of students have used anabolic substances. Quite interesting is the emergence of the fact of doping without a scientific supervision. The survey reveals that most of those who use anabolic substances have been supplied either by themselves or by a shop selling sportswear, either through a gym, either via the internet, or by their coach while few seem to have been supplied through their Sports Doctor.

Το κοινωνικό κεφάλαιο, πρωτεύων και απαραίτητος συντελεστής ανάπτυξης, αποτελεί σήμερα πηγή δυναμικής επιστημονικής έρευνας. Θεωρείται πυρηνική έννοια στην κοινωνιολογία, στην πολιτική επιστήμη, στην επιστήμη της συμπεριφοράς, στην οικονομία, στους τομείς της διοίκησης και της οικονομικής επιχειρηματικότητας αλλά αποτελεί σχετικά καινούργια έννοια στον αθλητισμό, στην αθλητική διοίκηση και ηγεσία. Η εργασία αυτή προβαίνει σε μία συστηματική ανασκόπηση των θεωρητικών προσεγγίσεων και εμπειρικών ερευνών περί κοινωνικού κεφαλαίου με στόχο την προσέγγιση της κοινωνικής περιοχής του αθλητισμού υπό την οπτική της ανάλυσης του κοινωνικού κεφαλαίου. Η διεθνής βιβλιογραφία στο θέμα Αθλητισμός ως Κοινωνικό Κεφάλαιο (Walseth 2008, Nicholson & Hoye 2008, Tonts 2005), μολονότι περιορισμένη, αναδεικνύει ότι όσο ισχυρότερο είναι το κοινωνικό κεφάλαιο που αποκτάται στο πεδίο του αθλητισμού τόσο διευκολύνεται-προωθείται η κοινωνική ενσωμάτωση. Με επίκεντρο τη θεωρητική προσέγγιση και τα τεκμηριωμένα στοιχεία του Robert Putnam (2000, 2004) - και ιδιαίτερα η διάκριση μεταξύ των δύο διαστάσεων του κοινωνικού κεφαλαίου: «γεφυροποιό-έμμεσο» και «περιοριστικό-αποκλειστικό» - πραγματευόμαστε την κοινωνική περιοχή του αθλητισμού. Οι θεωρητικές προσεγγίσεις του Putnam - που διαφέρουν από εκείνες του Bourdieu (1983,1986) - έχουν δεχτεί έντονη κριτική (Adkins 2005, Misztal 2005, Morrow 2003, 2004, Etzioni 2001). Ωστόσο έχουν συμβάλλει δυναμικά στην έρευνα και αποτελούν χρήσιμο εργαλείο ανάλυσης, ειδικά στις έρευνες που εξετάζουν το κοινωνικό κεφάλαιο του αθλητισμού (Walseth 2008, et al). Εξερευνώντας τη συνάφεια του αθλητισμού και του κοινωνικού κεφαλαίου, διακρίνουμε ότι θεωρητικά και πρακτικά ο αθλητισμός είναι δυνατόν να προσδιοριστεί ως «γεφυροποιό- έμμεσο» κοινωνικό κεφάλαιο που προωθεί κοινωνική ενσωμάτωση, αλληλεγγύη, ισότητα, κτλ., όπως δείχνει και η ανασκόπηση των δραστηριοτήτων μη-κυβερνητικών οργανώσεων, όπως οι PeaceFirst (Peace Games) και Sport in Society (SIS), που αγωνίζονται για την εισαγωγή μιας παιδαγωγικής ειρήνης (peace education) στη δημόσια εκπαίδευση. Ταυτόχρονα, ο αθλητισμός μπορεί να προσεγγιστεί και ως κοινωνική περιοχή που αναπαράγει «περιοριστικό-αποκλειστικό» κοινωνικό κεφάλαιο ή ακόμα και σκοτεινό κοινωνικό κεφάλαιο, δεδομένου ότι η πολιτική του αθλητισμού δεν συντελεί πάντα στην πρόοδο - αν λάβουμε υπόψη την εμπορευματοποίηση, το ντόπινγκ, τη φυλετική βία στα γήπεδα, τις περιβαλλοντικές επιπτώσεις των Ολυμπιακών έργων, την κραυγαλέα υποεκπροσώπηση των γυναικών στους αθλητικούς θεσμούς, την «αθλητική μετανάστευση», το «αθλητικό εργατικό δυναμικό», την αφαίρεση της εθνικής ταυτότητας του «παγκόσμιου αθλητή-μετανάστη» (Takahashi & Horne, 2006) και ειδικά την απώλεια αυτού του αθλητικού δυναμικού στη χώρα προέλευσης (social capital drain). Ο αθλητισμός-ανεκμετάλλευτη πηγή κοινωνικής ενέργειας—έχει τη δυνατότητα να εξελιχθεί σε μια μορφή «γεφυροποιού» κοινωνικού κεφαλαίου. Στη λογική αυτή, δεδομένου ότι ο αθλητισμός αποτελεί παγκόσμιο φαινόμενο και πολιτιστικό θεσμό, προτείνεται ο επαναπροσδιορισμός των ηθικών του πλαισίων: διαμόρφωση εναλλακτικών προτάσεων, αθλητικών μοντέλων και προτύπων, επανενεργοποίηση των Ολυμπιακών αξιών.

The purpose of this case study is the presentation of the adverse long-term consequences of school bullying. This case study concerns a 22-year-old female who sought out therapy in order to cope with her intense negative feelings of stress and depression. During the therapeutic process, it became clear that the patient's current problems were related to having been the victim of systematic bullying during her school years. Her self-image in the period she sought out help deteriorated, as shown in her negative cognitions regarding her abilities and capacities, which had been shaped under the influence of the bullying experience. According to a number of empirical investigations (Hawker & Boulton, 2000; Nansei, Craig, & Overpeck, 2004; Kochenderfer & Ladd, 1996; Kochenderfer & Wardrop, 2001; and in Greece: Galanaki & Vogiatzoglou, 2007; Galanaki, Amanaki, & Noikokiri, 2009), some of the consequences of school bullying - such as relationship problems, low self-esteem, limited social contacts, stress, depression, feelings of loneliness - are likely to be maintained for an extended period of time, especially when the individual has failed to form a network of social support (Newman, Holden, & Delville, 2004). Thus, adults who as pupils suffered from bullying experience more feelings of loneliness, depression, and inadequacy and they encounter difficulties in their interpersonal relations (Gilmartin, 1987; Hugh-Jones & Smith, 1999; Isaacs, Hodges, & Salmivalli, 2008; Newman et al., 2005; Olweus, 1994; Storch, Roth, Cales, Heimberg, Bravata, & Moser, 2004). In this case study, the ongoing presence and lasting influence of these negative consequences in adult life become obvious.
Πρόκειται για το κείμενο της ανακοίνωσης στην διεπιστημονική ημερίδα με θέμα «Ελληνογερμανικές σχέσεις: αλληλοεπιδράσεις στον πολιτισμό και την τέχνη», που διοργάνωσε το Εργαστήριο Συγκριτικής Γραμματολογίαςτου Τμήματος Γαλλικής Γλώσσας και Φιλολογίας του Αριστοτελείου Πανεπιστημίου Θεσσαλονίκης στη Θεσσαλονίκη και έλαβε χώρα την 6η Απριλίου 2011 (http://www.del.auth.gr/de/forschung/weitere-veranstaltungen/145-8-4-2011).
Το άρθρο αναφέρεται σε ορισμένες θέσεις της έρευνας, σχετικά με τα χαρακτηριστικά και τις παραλείψεις της πρόσληψης του έργου του Χάινριχ Χάινε στην Ελλάδα, θέσεις που αναπτύσσονται διεξοδικά στην μονογραφία της γράφουσας. Αναφέρεται εδώ και συζητείται ακροθιγώς η άποψη σχετικά με τον αποφασιστικό ρόλο που έπαιξε ο ποιητικός λόγος του Χάινε κατά τη διαδικασία υπέρβασης του αθηναϊκού ρομαντισμού εκ μέρους των ποιητών της γενιάς του 1880, όπως και κατά την πρόσληψη ενός ειρωνικού, κριτικού και παιγνιώδους τρόπου έκφρασης, που εμπεριέχεται μεν εξαρχής στο γερμανικό ρομαντικό παράδειγμα (ρομαντική ειρωνεία), πλην όμως εισήλθε στον νεοελληνικό λογοτεχνικό λόγο κυρίως ως συνέπεια της επαφής, μεταξύ άλλων, με το έργο του Χάινε. Παρουσιάζεται με αδρές γραμμές η ιδιαίτερα ενδιαφέρουσα περίπτωση της πρόσληψης του ποιητή Heinrich Heine (1797-1856) στην Ελλάδα, που ξεκινά τον 19ο αιώνα και συνεχίζεται με διακυμάνσεις ως τις μέρες μας.
Στο άρθρο δίνεται πάντως έμφαση στην παρουσίαση του ποιητή και των ιδιοτήτων του έργου του, που τον καθιστούν αντιπροσωπευτικό συγγραφέα της αρχόμενης νεωτερικότητας, με την έννοια της μετάβασης από τον κλασικορομαντικό ποιητή μιας αισθητικής-ηθικής κοσμοθέασης στον μοντέρνο συγγραφέα και διανοούμενο μιας νεότερης εποχής, ο οποίος παρακολουθεί και σχολιάζει στο έργο του, θεωρητικό και λογοτεχνικό, την ρέουσα πραγματικότητα. Σημαντική θέση στο έργο του Χάινε έχουν οι αναφορές σε μορφές της ελληνικής μυθολογίας και αρχαιότητας που διατρέχουν το σύνολο του έργου του και συνθέτουν την ιδιότυπη προσωπική μυθολογία του ποιητή, η οποία κινείται στο μεταίχμιο ανάμεσα στην ελεγειακή αναπόληση μιας χαμένης αισθησιακής χαράς της ζωής και στην σπινθηροβόλα ειρωνική διάθεση του σχολιασμού της επικαιρότητας με το ένδυμα του μύθου. Προκύπτει το ερώτημα του τρόπου πρόσληψης στην Ελλάδα τόσο αυτής της διάστασης του έργου του Χάινε, όσο και των ιδιαίτερων υφολογικών και ρητορικών δομών των κειμένων του, ερώτημα, το οποίο αντιμετωπίζεται διεξοδικά στη μονογραφία της γράφουσας.
Το παρόν κείμενο αποτελεί πρόλογο του Καθηγητή Ιωάννη Θ. Μάζη στο έργο του Κυριακοῦ Θ. Νικολάου-Πατραγᾶ, "Τὸ μέλλον τῆς δημοκρατίας στὴν Αἴγυπτο: Ἡ συμβολὴ τοῦ ἱππότου Χάλεντ Μόχη ἀλ-Ντήν".
By means of full electrodynamic and elastodynamic multiple-scattering calculations we study the optical and acoustic properties of three-dimensional lattices of metallic nanospheres implanted in a dielectric host. Our results show that such structures exhibit omnidirectional spectral gaps for both telecom infrared light and hypersound, with relatively low absorptive losses. This class of dual (phoxonic) band-gap materials is an essential step toward the hypersonic modulation of light and could lead to the development of efficient acousto-optical devices.

OBJECTIVE: In obese postmenopausal women we assessed leptin and adiponectin, high-sensitive C-reactive protein (hsCRP), serum lipids and lipoxidative stress products: oxidized LDL (oxLDL) and malondialdehyde (MDA), in relation to impaired glucose tolerance (IGT).
METHODS: Thirty-eight overweight/obese postmenopausal women were included in the study. Eighteen with normal glucose metabolism (NGT) and twenty with IGT, as it is diagnosed by OGTT. Serum leptin, adiponectin, hsCRP and MDA were measured at time 0 and 120 min of OGTT while total-cholesterol, LDL, HDL, triglycerides, oxLDL and anti-oxLDL autoantibodies at time 0. Insulin resistance (HOMA)/sensitivity (QUICKI) indexes were estimated.
RESULTS: In subjects with NGT, hsCRP was positively correlated with fasting leptin and HOMA, while in subjects with IGT negatively with QUICKI. In both groups, hsCRP was positively correlated with fasting insulin, body mass index and waist circumference. Fasting adiponectin was positively associated with HDL in both groups and negatively with triglycerides in subjects with NGT as well as with serum glucose levels at time 120 min of OGTT in subjects with IGT. No association was observed between oxLDL and adipokines. A significant positive association was found between oxLDL and HOMA in subjects with IGT. During OGTT there was a significant increase of leptin and MDA levels in both groups.
CONCLUSIONS: A relationship exists between obesity, insulin and sub-clinical inflammation. Leptin and lipid peroxidation are linked to hyperglycaemic state while oxLDL might be considered as a predictor of insulin resistance. Adiponectin could exert its antiatherogenic effect through HDL independently of the presence of IGT.
The present study provides additional data on the distributional range of six alien foraminiferal species in living assemblages from Greek coastal areas (Aegean Sea, Eastern Mediterranean). Amphistegina lobifera LARSEN 1976, Sorites orbiculus (FORSK L 1775) and Coscinospira hemprichii EHRENBERG 1839 are well established in Greek coastal areas, whereas Triloculina fichteliana D'ORBIGNY 1839, Planogypsina acervalis (BRADY 1884) and Cymbaloporetta plana (CUSHMAN 1924), are recorded for the first time in this paper. The occurrence of these species in a number of sites in the Aegean Sea establishes their presence in the Eastern Mediterranean.
Although extensively studied for its pharmaceutical properties, Teucrium polium has yet to disclose its leaf structure and the chemical nature of the accumulated or secreted products. Therefore, light, scanning, and transmission electron microscopy along with histochemical tests were employed to investigate the leaf of this perennial dwarf Mediterranean shrub. Structural characteristics include large cells with cutinized walls, creating cavities of obscured function in contact to a vessel element of the conductive tissue and different types of glandular hairs. A variety of secreted materials was identified by certain histochemical stains within the mesophyll cells and the glandular hairs. A dense indumentum of non-glandular hairs protects the secretory apparatus and the leaf surface from the stressful conditions of the Mediterranean climate.
Pietsch, Henze, and Burwitz -- together with A. Liakos (Department of Physics, University of Athens), D. Hatzidimitriou (Department of Physics, University of Crete), and P. Niarchos (Department of Physics, University of Athens) -- add that confirmation of M31N 2010-06c at mag 18.0 was obtained with a stack of ten 60-s unfiltered CCD images obtained with a 40-cm Cassegrain telescope (+ f/5.1 focal reducer + 2184x1472-pixel ST-10XME CCD camera; pixel size 6.8 microns square) at the Athens University Observatory on June 27.028 UT; they provide position end figures 04s.48, 33".8.
W. Pietsch, M. Henze, and V. Burwitz, Max-Planck-Institut fuer Extraterrestrische Physik; A. Liakos, Department of Physics, University of Athens; D. Hatzidimitriou, Department of Physics, University of Crete; and P. Niarchos, Department of Physics, University of Athens, report the detection of an apparent nova in M31 using observations with the UltraViolet/Optical Telescope (UVOT) onboard the Swift satellite. The object was serendipitously detected in the UVW1 filter (range 181-321 nm; UVOT observation number 31255018 with 4333-s exposure) starting on June 24.02 UT with a magnitude of 19.5 +/- 0.2. The position for the nova candidate, designated M31N 2010-06d, is R.A. = 0h42m55s.56, Decl. = +41d19'25".5 (equinox 2000.0; uncertainty 1".0), which is 127" east and 197" north of the core of M31. The source is clearly detected in the individual images. In the UVW1 filter, Swift observation number 31255014, starting on June 12.04 (4161-s exposure), and in the U filter, Swift observation number 31255017, starting on June 21.29 (1330-s exposure), no object was detected at the position of M31N 2010-06d, with limiting magnitudes of 20.5 and 19.7 (3 sigma), respectively. (All magnitudes are on the UVOT photometric system of Poole et al. 2008, MNRAS 383, 627, and have not been corrected for extinction.) M31N 2010-06d was confirmed on a stacked unfiltered CCD image composed of ten 60-s frames obtained at a 40-cm Cassegrain telescope with a focal reducer (f/5.1) equipped with a 2184x1472-pixel ST-10XME CCD camera (pixel size 6.8 microns square) at the Athens University Observatory on July 1.082 UT, yielding magnitude 17.8 (obtained from a photometric solution using R magnitudes of the Local Group Survey M31 catalogue of Massey et al. 2006) and position end figures 55s.62, 25".7 (uncertainty 0".5), fully consistent with the position of the Swift source. M31N 2010-06d is visible in the UV filter already several days before the detection in the optical (similar to novae M31N 2009-08a and M31N 2010-01b). Public data from the Swift data archive was used. Kamil Hornoch, Ondrejov Observatory, reports the independent discovery of M31N 2010-06d by Marek Wolf and himself on co-added 1620-s and co-added 1350-s R-band CCD frames taken by Hornoch on June 30.003 UT and by Wolf on July 1.022, respectively, with the 0.65-m telescope at Ondrejov. M31N 2010-06d is marginally visible on single images used for the co-added frames. Also, the new object is visible on pre-discovery co-added R-band frames taken with the same instrumentation during three previous nights, but is not present on numerous archive images taken at Ondrejov. M31N 2010-06d is located at R.A. = 0h42m55s.53, Decl. = +41o19'25".0 (equinox 2000.0), which is 126" east and 196" north of the center of M31. Available R-band magnitudes for M31N 2010-06d, measured by Hornoch: June 9.459 UT, [21.7 (P. Garnavich, C. Littlefield, N. Paul, and S. Bouzid, 1.83-m Vatican Advanced Technology Telescope); 18.152, [21.1 (P. Kubanek, J. Gorosabel, O. Lara-Gil, and M. Jelinek, 1.23-m telescope at Calar Alto); 27.034, 20.1 +/- 0.3 (K.

The high quality stellar spectra, recorded with the stellar spectrograph constructed at the Laboratory of Astronomy and Applied Optics of the University of Athens, allows the spectral classification of stars brighter than 9 mag, as well as the measurement of radial velocities of binary systems. The primary application of the spectrograph will be the study of eclipsing binaries, where the lack of spectroscopic observations limits the theoretical models. The spectrograph can be also used for observations of transient phenomena, such as novae, supernovae, comets and cataclysmic variable stars, but also for support observations of larger telescopes around the world.
Are Eccentric Strength Asymmetries Connected with Increased Risk for Muscle Injuries in the Thigh Muscles of Professional Soccer Players?
Konstantinos Fousekis, Elias Τsepis, George Vagenas
Introduction. The purpose of this prospective study was to statistically evaluate the relation between isokinetic strength asymmetries and risk of non-contact muscle strains in soccer. Methods. One hundred professional soccer players (age 23.4±4.8 years, height 178±6.7 cm, body mass 74.2±7.6 kg) were tested for isokinetic concentric and eccentric strength during the extension and flexion of the knee and ankle joint. Isokinetic testing was carried-out concentrically at 60o /sec. 180o/sec & 300o/sec and eccentrically at 60o/sec & 180o/sec for the knee joint. The ankle joint was tested at 60o/sec for both the concentric and eccentric mode of action. Each players? non-contact muscle strains resulting in missing at least one practise session or game were recorded during one competition season. Results. Analysis of the composite muscle strength asymmetries showed a significantly high relative risk of injury for players with eccentric strength asymmetries greater than 15% (RR=5.10; 95% CI: 1.29-20.17). Τhe majority of muscle strains involved 16% the hamstrings and 7% the quadriceps. The relative risk for strains in knee extensors strains was significantly increased in players with eccentric muscle asymmetries >15% (RR=1.93, 95% CI: 0.81- 4.56) and approximated statistical significance in the case of knee flexors strains (RR=1.82, 95% CI: 0.86-3.87). No significant relationship was found between concentric muscle strength asymmetries and muscle strains. Conclusions. Players with eccentric isokinetic strength asymmetries higher than 15% were more prone to injure their lower extremities. Preseason eccentric isokinetic assessment is required for the identification of soccer players being at high risk of thigh muscle strain and for the prevention of potential muscle strains via individualized exercise protocols.
INTRODUCTION: the FcgammaRIIa receptor is responsible for the clearance of large immune complexes and recently has been proved to be a C-reactive protein (CRP) receptor as well. A polymorphism in the corresponding FCG2RA gene resulting in an amino acid change (R131H) has been implicated, with conflicting results in the pathogenesis of various autoimmune or inflammatory disorders (e.g., atherosclerosis and coronary artery disease [CAD]). METHODS: we recently developed a real-time polymerase chain reaction and melting curve analysis method for the genotyping of the above polymorphism. We further looked at its validity with bioinformatics study and DNA sequencing. Then we genotyped 134 CAD patients and 45 angiographically normal controls and determined serum high-sensitivity CRP by nephelometry (Dade-Behring). Also, we used apparently healthy platelet donors (n = 206) as a larger control group. RESULTS: our method is accurate and devoid of problems with homologs and copy number variants. The need for reference materials is stressed. There were statistically significant differences (p < 0.05) between the CAD patients and each of the two other control groups, with the percentage of RR genotype rising from 6.5% and 11% in the control groups to an average of 19% in all CAD patients (17%, 24%, and 18.5% in stable angina, unstable angina, and myocardial infarction, respectively). In a logistic regression model that included known risk factors for CAD including CRP, the RR genotype remained a significant predictor for CAD (odds ratio: 6.3 [1.1-36.3]). Also after linear regression analysis, CRP levels were reduced in the RR carriers (vs. HH + HR), controlling for age, sex, and disease (marginal p = 0.07). CONCLUSIONS: with our accurate genotyping method, the RR genotype was correlated with atherothrombotic CAD events. The inverse correlation found between CRP levels and genotype supports the in vitro data of RR cells binding CRP stronger than HH

Studies have suggested that dental development substantially influences the variation of mandibular morphology and growth in primates. As a contribution to the methodology of such studies, we introduce a novel approach to quantifying the covariation between teeth and mandible. This was done showing fluctuations in the magnitude of this covariation within a sample of modern human mandibles at different postnatal ages. Dense CT- derived mandibular surface meshes of 73 females and 71 males, ranging in age from birth to adulthood, were processed by methods of geometric morphometrics. Each specimen's deciduous and permanent teeth were rated for mineralization stage. Form-space principal component analysis of the morphometric data was used to produce a single metric variable that best explains mandibular-form variation. This variable was then used to quantify the developing teeth, all together, through the use of the additive conjoint measurement method. This new metric variable corresponds to the dental prediction of the mandibular-form variation. Finally, we examine the covariation of the two over the full range of mineralization stages. We found a strikingly tight association between mandibular form and dental maturation up through the full emergence of the deciduous dentition (about age 2 years), followed by an equally striking decline in that association in later developmental stages, particularly for girls. The onset of the decline of the teeth-mandible relationship coincides with the onset time of the adult-like pattern of mastication and speech. The increasingly functional diversity may lead to more independence between dental development and mandibular growth than during the first two years.
AIM: Leptin and adiponectin are two well-studied adipokines in relation to malignancies. In this study, we examined the association between leptin/adiponectin and risk of B-cell chronic lymphocytic leukemia (B-CLL), as well as the relationships between adipokines and several established prognostic factors of B-CLL.
METHODS: Ninety-five patients with incident B-CLL and 95 hospital controls matched on age and gender were studied between 2001 and 2007, and blood samples were collected. Leptin, total and high molecular weight adiponectin, and prognostic markers of B-CLL were determined.
RESULTS: Cases had a higher body mass index (BMI) than controls (p = 0.01) and lower levels of leptin (p < 0.01). Significantly more cases than controls presented a family history of lymphohematopoietic cancer (LHC) (p = 0.01). Higher serum leptin levels were associated with lower risk of B-CLL adjusting for age, gender, family history of LHC, BMI and serum adiponectin; the multivariate odds ratio comparing highest to lowest tertile was 0.05 (95% CI 0.01-0.29, p trend < 0.001); Adiponectin was not significantly different between cases and controls.
CONCLUSION: Leptin was found to be inversely associated with risk of CLL but in contrast to prior studies of CLL and hematologic malignancies, this study found no significant association between CLL and adiponectin.
(2010). Beijing 2008: Οι Ολυμπιακοί Αγώνες στη «Χώρα του Δράκου» και το γεωπολιτικό παιχνίδι στη «στέγη του κόσμου».
Το Πεκίνο, η καρδιά της Κίνας, της πολυπληθέστερης χώρας του πλανήτη, υποδέχτηκε τους 29ους Ολυμπιακούς Αγώνες το 2008. Ποια είναι τα βασικά χαρακτηριστικά της ιδιαίτερης αυτής χώρας από απόψεως ιστορίας, φιλοσοφίας και πολιτικής; Μέσα από ποιες διεργασίες το κομμουνιστικό κόμμα διαδέχτηκε το αυτοκρατορικό σύστημα; Η χώρα του Κομφούκιου και του Μάο Τσε Τούνγκ συνιστά σήμερα ένα εξαιρετικά πολύπλοκο κράτος, όπου η τυραννία και η ελευθερία συνυπάρχουν, μαζί με την πρόοδο και την ελπίδα. Η χώρα του «κόκκινου καπιταλισμού» με αφορμή τους Ολυμπιακούς Αγώνες θα εκμεταλλευόταν την ευκαιρία να δείξει σε όλο τον πλανήτη πόσο μεγάλη και ισχυρή έχει γίνει. Ποιο είναι, όμως, σήμερα το γεωπολιτικό παιχνίδι στη «στέγη του κόσμου»; Ποιες οι αρχές του λαμαϊσμού (του θιβετιανής εκδοχής βουδισμού), όπως τις εκφράζει με τη στάση και τη φιλοσοφία του ο σημερινός 14ος Δαλάι Λάμα; Ο εξόριστος ηγέτης των Θιβετιανών και τιμημένος με το βραβείο Νόμπελ Ειρήνης, ο μοναχός που λατρεύεται ως θεός από τους βουδιστές του κόσμου, έχει επιδιώξει το συγκερασμό μεταξύ πολιτικής και πνευματικότητας, σήμερα τάσσεται υπέρ της παγκοσμιοποίησης και υποστηρίζει την αυτονομία του Θιβέτ. Κατά τη διάρκεια των Ολυμπιακών Αγώνων του Πεκίνου η πολιτική εξουσία δεν έμεινε μακράν των αγώνων, με αφορμή την ανελευθερία και την καταπάτηση των ανθρωπίνων δικαιωμάτων στην Κίνα. Στο μεταξύ, η κρίση στον Καύκασο τίναξε την οποιαδήποτε συζήτηση περί «ολυμπιακής εκεχειρίας» στον αέρα. Στη συνέχεια, πάντως, η όλη διοργάνωση υπήρξε ανάλογη ενός ανερχόμενου γίγαντα όπως είναι σήμερα η Κίνα. Με την αισθητική του σκηνοθέτη Ζανγκ Γιμού συναντήθηκε ο αρχαίος πολιτισμός της με τη σύγχρονη αισθητική, σαν ταινία μυστηρίου και φαντασμαγορίας. Η Κίνα του 21ου αιώνα είναι αναμφισβήτητα μια από τις ηγέτιδες δυνάμεις του σύγχρονου κόσμου. Παρά την γιγαντιαία διοργάνωση, ωστόσο, σημειώθηκαν και ευτράπελα στην Made in China κινεζική τελειότητα.
Magnetic particles are currently applied to special biomedical and environmental applications owing to their unique magnetic, morphological and substance-carrying capabilities. Very recently we introduced Magnetically Assisted Hemodialysis (MAHD), an innovative therapeutic application of Ferromagnetic Nanoparticles (FNs) for the treatment of End-Stage Renal Disease (ESRD). MAHD can be employed for the selective and efficient removal of toxins that, although of high biological importance, they cannot be handled by current Hemodialysis strategies. This work is focused on evaluating the biocompatibility of Fe3O4 FNs with cells of donated human blood, namely Red Blood Cells (RBCs), White Blood Cells (WBCs) and Platelets (Pits). To that end, optical microscopy and atomic force microscopy were employed for the morphological examination of blood cells that were maturated under the presence of Fe3O4 FNs by means of mild incubation up to 120 min at T = 20 degrees C. As a conclusion we have not detected noticeable interference between RBCs, WBCs and Pits with FNs for the maturation conditions and the extreme FNs concentrations examined in this work.
