    Full Text Available The purpose of this article is to give an overview of different molecular techniques which have been used in studies concerning population genetic issues of Lepus species and specifically of L. europaeus. The importance of these researches is ever-growing as the European populations of the brown hare have suffered several falloffs as a consequent upon both natural and anthropogenic effects. With developing tools and techniques molecular genetics have become the centrepiece of population genetics and conservation biology. Nucleic acid methods based on both bi- and uniparentally inherited DNA (allozymes, microsatellites, Y chromosome, mtDNA are often used to study genetic structure, diversity and phylogeography of different species’ populations due to their effectiveness in identifying genetic variability

    Full Text Available The study of Western countries and teaching courses on the related subjects have longstanding and established tradition at MGIMO-University. The basis of this brilliant research and teaching tradition was laid down by such academicians as E.V. Tarle and V.G. Trukhanovsky, Professor L.I. Clove, Y. Borisov, F.I. Notovitch, G.L. Rozanov. Their work in 1940-1960's at the Department of World History at MGIMO-University progressed in following directions: France studies, German studies, American studies. The work resulted in a number of monographs and textbooks on modern history and foreign policy of the studied countries and regions. The aim of the publications was dictated by the goal of the Institute - to prepare the specialists in international affairs primarily for practical work. A close relationship with the Foreign Ministry was "binding advantage" sometimes limiting researchers in choosing periods and subjects for the study. At the same time the undisputed advantage and quality of regional studies at MGIMO were strengthened by the practical relevance of research, making it a vital and interesting not only for specialists but also for students and researchers from other research centers. Another characteristic of the tradition is the analysis of foreign policy and diplomacy in a close relationship with the socio-economic and political processes. Such an integrated approach to regional geography also formed largely under the influence of institutional profile designed to train highly skilled and versatile specialists in specific countries and regions with a good knowledge of their languages, history, economics, politics, law and culture. Therefore, scientific and educational-methodical work at MGIMO-University has always relied on a wealth of empirical data and has been focused on the analysis of real-world phenomena and processes, acute problems of foreign countries. Scientific research at MGIMO-University traditionally intertwined with

    Full Text Available Open Science has gained a lot of attention not only within the academic community but also among policy-makers. Some international publishers have been active in moving towards open access publications and research data, but, overall, modest results have been achieved so far. In this context, the digital piracy engines emerge as vital actors in disseminating and determining the impact of research. This study examines the Sci-Hub downloads data in order to uncover patterns of piracy in European Studies research. We identify journals and the subjects of articles that have been pirated the most. We also study the geographical distribution of download requests. The analysis reveals that the readers are mostly interested in subjects reflecting the current major European challenges, specifically populism and the economic crisis. Both developing countries as well as the ‘old’ EU members are active in illegal downloads.

    Full Text Available Soviet scientific school of pan-European integration studies began to emerge in the 1960s at the Institute of World Economy and International Relations (Russian Academy of Science. Among the leading scientists who have developed methodological approaches of Soviet integration studies were M.M. Maximova, Y.A. Borko, Y. Shishkov, L.I. Capercaillie. Later, a new center for integration studies became the Institute of Europe, created in 1987. It was led by such renowned scientists as Academicians V.V. Zhurkin and N.P. Shmelev. In the 1980s the subject of the integration process in Europe attracted attention of experts from MGIMO. An important role in the development of school of integration research in the USSR was played by a MGIMO professor, head of the chair of history of international relations and foreign policy of the USSR V.B. Knyazhinskiy. His work contributed to the deliverance of the national scientific community from skepticism about the prospects for European integration. Ideas of V.B. Knyazhinsky are developed today in MGIMO by his followers A.V. Mal'gin and T.V. Ur'eva. In the mid-1990s, having retired from diplomatic service, professor Yu. Matveevskiy started to work at MGIMO. With a considerable practical experience in the field, he produced a series of monographs on the history of European integration. In his works, he analyses the development of integration processes in Western Europe from their inception to the present day, showing the gradual maturation of the necessary spiritual and material prerequisites for the start of integration and traces the various stages of the "integration". In the late 1990s, the growing demand from the domestic business and government for professionals who are capable of interacting with the European Union, has produced the necessary supply in the form of educational programs based on accumulated scientific knowledge. Setting up a discipline "European Integration" was a major step in the development

    Reliable atomic and molecular data are of great importance for different applications in astrophysics, atmospheric physics, fusion, environmental sciences, combustion chemistry, and in industrial applications from plasmas and lasers to lighting. Currently, very important resources of such data are highly fragmented, presented in different, nonstandardized ways, available through a variety of highly specialized and often poorly documented interfaces, so that the full exploitation of all their scientific worth is limited, hindering research in many topics like e.g. the characterization of extrasolar planets, understanding the chemistry of our local solar system and of the wider universe, the study of the terrestrial atmosphere and quantification of climate change; the development of the fusion rersearch, etc. The Virtual Atomic and Molecular Data Centre (http://www.vamdc.eu, VAMDC) is an European Union funded FP7 project aiming to build a secure, documented, flexible and interoperable e-science environment-based interface to existing atomic and molecular data. It will also provide a forum for training potential users and dissemination of expertise worldwide. Partners in the Consortium of the Project are: 1) Centre National de Recherche Scientifique - CNRS (Paris, Reims, Grenoble, Bordeaux, Dijon, Toulouse); 2) The Chancellor, Masters and Scholars of the University of Cambridge - CMSUC; 3) University College London - UCL; 4) Open University - OU; (Milton Keynes, England); 5) Universitaet Wien - UNIVIE; 6) Uppsala Universitet - UU; 7) Universitaet zu Koeln - KOLN; 8) Istituto Nazionale di Astrofisica - INAF (Catania, Cagliari); 9) Queen's University Belfast - QUB; 10) Astronomska Opservatorija - AOB (Belgrade, Serbia); 11) Institute of Spectroscopy RAS - ISRAN (Troitsk, Russia); 12) Russian Federal Nuclear Center - All-Russian Institute of Technical Physics - RFNC-VNIITF (Snezhinsk, Chelyabinsk Region, Russia; 13) Institute of Atmospheric Optics - IAO (Tomsk, Russia

    Bat rabies cases in Europe are mainly attributed to two lyssaviruses, namely European Bat Lyssavirus 1 (EBLV-1) and European Bat Lyssavirus 2 (EBLV-2). Prior to the death of a bat worker in Finland in 1985, very few bat rabies cases were reported. Enhanced surveillance in the two subsequent years (1986-1987) identified 263 cases (more than a fifth of all reported cases to date). Between 1977 and 2016, 1183 cases of bat rabies were reported, with the vast majority (>97%) being attributed to EBLV-1. In contrast, there have been only 39 suspected cases of EBLV-2, of which 34 have been confirmed by virus typing and presently restricted to just two bat species; Myotis daubentonii and Myotis dasycneme . The limited number of EBLV-2 cases in Europe prompted the establishment of a network of European reference laboratories to collate all available viruses and data. Despite the relatively low number of EBLV-2 cases, a large amount of anomalous data has been published in the scientific literature, which we have here reviewed and clarified. In this review, 29 EBLV-2 full genome sequences have been analysed to further our understanding of the diversity and molecular evolution of EBLV-2 in Europe. Analysis of the 29 complete EBLV-2 genome sequences clearly corroborated geographical relationships with all EBLV-2 sequences clustering at the country level irrespective of the gene studied. Further geographical clustering was also observed at a local level. There are high levels of homogeneity within the EBLV-2 species with nucleotide identities ranging from 95.5-100% and amino acid identities between 98.7% and 100%, despite the widespread distribution of the isolates both geographically and chronologically. The mean substitution rate for EBLV-2 across the five concatenated genes was 1.65 × 10 -5 , and evolutionary clock analysis confirms the slow evolution of EBLV-2 both between and within countries in Europe. This is further supported by the first detailed EBLV-2 intra

    The molecular basis of 5{alpha}-reductase (5{alpha}R) deficiency was investigated in four patients from three European families. In the French family, the first patient was raised as a female, and gonadectomy was performed before puberty. The second sibling, also raised as female, differed in that gonadal removal was performed after the onset of pubertal masculinization. The other two patients, both from Polish families, developed masculinization of external genitalia during puberty. All patients developed a female sexual identity. In all cases, no known consanguinity or family history of 5{alpha}R deficiency was reported. The genomic DNAs of the patients were sequenced after polymerase chain reaction amplification of the five exons of the 5{alpha}R type 2 gene. We found two homozygous mutations responsible for gutamine to arginine and histidine to arginine substitution in families 1 and 3, respectively. In family 2, we found a heterozygous mutation responsible for an asparagine to serine substitution at position 193. The glutamine/arginine 126 mutation in the French family was previously reported in a Creole ethnic group, and the Polish histidine/arginine 231 mutation was previously reported in a patient from Chicago, Moreover, all of the mutations created new restriction sites, which were used to determine the kindred carrier status in the three families. Because 5{alpha}R deficiency is known to be heterogenous disease in terms of clinical and biochemical expression, our data suggest that molecular biology analysis of the type 2 gene could be an essential step in diagnosing 5{alpha}R deficiency. 22 refs., 3 figs., 1 tab.

    Cade's discovery of lithium's antimanic effect soon became known in Europe and was confirmed by a Danish controlled trial. The same investigators discovered a prophylactic action of lithium against both manic and depressive recurrences, which was confirmed by a Swiss-Czech-Danish cooperative trial. The evidence of these studies was met with skepticism based on methodological speculations, but a Danish randomised, placebo-controlled, double-blind trial of discontinuation design established the prophylactic action of lithium, as did a number of European controlled trials of start design and discontinuation design. The review ends with personal memories of John Cade.

    This special section of Comments on Atomic, Molecular and Optical Physics (CAMOP) in Physica Scripta collects some of the papers that have been presented at the 18th European Conference on Dynamics of Molecular Systems MOLEC 2010 held in September 2010 in Curia, Portugal, as part of a series of biennial MOLEC conferences. This started in 1976 in Trento, Italy, and has continued, visiting 17 cities in 11 countries, namely Denmark, The Netherlands, Israel, France, Italy, Germany, Czech Republic, Spain, United Kingdom, Turkey and Russia. Following the MOLEC tradition, the scientific programme of the Curia meeting focused on experimental and theoretical studies of molecular interactions, collision dynamics, spectroscopy, and related fields. It included invited speakers from 22 countries, who were asked to summarize the problems reported in their presentations with the objective of revealing the current thinking of leading researchers in atomic, molecular and optical physics. It is hoped that their authoritative contributions presented in this CAMOP special section will also appeal to non-specialists through their clear and broad introductions to the field as well as references to the accessible literature. This CAMOP special section comprises ten contributions, which cover theoretical studies on the electronic structure of molecules and clusters as well as dynamics of elastic, inelastic and reactive encounters between atoms, molecules, ions, clusters and surfaces. Specifically, it includes electronic structure calculations using the traditional coupled-cluster method (Barreto et al 028111), the electron-attached equation-of-motion coupled cluster method (Hansen et al 028110), the diffusion Monte Carlo method (López-Durán et al 028107) and the path-integral Monte Carlo method (Barragán et al 028109). The contributions on molecular dynamics include on-the-fly quasi-classical trajectories on a five-atom molecule (Yu 028104), quantum reaction dynamics on triatomics

    The diagnosis of ventilator-associated pneumonia (VAP) remains time-consuming and costly, the clinical tools lack specificity and a bedside test to exclude infection in suspected patients is unavailable. Breath contains hundreds to thousands of volatile organic compounds (VOCs) that result from host and microbial metabolism as well as the environment. The present study aims to use breath VOC analysis to develop a model that can discriminate between patients who have positive cultures and who have negative cultures with a high sensitivity. The Molecular Analysis of Exhaled Breath as Diagnostic Test for Ventilator-Associated Pneumonia (BreathDx) study is a multicentre observational study. Breath and bronchial lavage samples will be collected from 100 and 53 intubated and ventilated patients suspected of VAP. Breath will be analysed using Thermal Desorption - Gas Chromatography - Mass Spectrometry (TD-GC-MS). The primary endpoint is the accuracy of cross-validated prediction for positive respiratory cultures in patients that are suspected of VAP, with a sensitivity of at least 99% (high negative predictive value). To our knowledge, BreathDx is the first study powered to investigate whether molecular analysis of breath can be used to classify suspected VAP patients with and without positive microbiological cultures with 99% sensitivity. UKCRN ID number 19086, registered May 2015; as well as registration at www.trialregister.nl under the acronym 'BreathDx' with trial ID number NTR 6114 (retrospectively registered on 28 October 2016).

    Full Text Available Background: Achondroplasia (ACH is the most frequent form of short-limbed dwarfi sm, caused by mutations in the FGFR3 gene. It follows an autosomal dominant inheritance, though most cases are sporadic. The molecular techniques are the only available methods to confi rm the diagnosis of a skeletal dysplasia. Clinical and radiological features are only suggestive and not confi rmatory. The present study was conducted to fi nd out how often the clinical diagnosis of achondroplasia is verifi ed on molecular studies. Materials and Methods: From 1998 through 2007, we carried out molecular analysis for the two common mutations in the FGFR3 gene in 130 cases clinically suspected to have ACH. Results: A diagnostic mutation was identifi ed in 53 (40.8% cases. The common mutation (1138G>A was present in 50 (94.7% of the positive cases, while the rare 1138 G>C substitution was found in three (5.3%. Conclusion: This study shows that confi rmation of clinical diagnosis of ACH by molecular genetic testing is essential to distinguish it from other skeletal dysplasias, to plan therapeutic options, and to offer genetic counseling. Management (medical and surgical in patients confi rmed to have ACH, is briefl y discussed.

    IntroductionExpanding access to HIV antiretroviral treatment is expected to decrease HIV incidence and acquired immunodeficiency syndrome (AIDS) mortality. However, this may also result in increased HIV drug resistance (DR). Better monitoring and surveillance of HIV DR is required to inform treatment regimens and maintain the long term effectiveness of antiretroviral drugs. As there is currently no formal European Union (EU)-wide collection of HIV DR data, this study aimed to assess the current HIV molecular surveillance capacity in EU/European Economic Area (EEA) countries in order to inform the planning of HIV DR monitoring at EU level. Methods: Thirty EU/EEA countries were invited to participate in a survey on HIV molecular surveillance capacity, which also included laboratory aspects. Results: Among 21 responding countries, 13 reported using HIV sequence data (subtype and/or DR) for surveillance purposes at national level. Of those, nine stated that clinical, epidemiological and sequence data were routinely linked for analysis. Discussion/conclusion: We identified similarities between existing HIV molecular surveillance systems, but also found important challenges including human resources, data ownership and legal issues that would need to be addressed.Information on capacities should allow better planning of the phased introduction of HIV DR surveillance at EU/EEA level.

    The “gold standard” for post-mortem rabies diagnosis is the direct fluorescent antibody test (FAT). However, in the case of ante-mortem non-neural sample material or decomposed tissues, the FAT reaches its limit, and the use of molecular techniques can be advantageous. In this study, we developed......-systems for Rabies virus, European bat lyssavirus type 1 and 2 as well as Bokeloh bat lyssavirus. All assays were validated successfully with a comprehensive panel of lyssavirus positive samples, as well as negative material from various host species.

  3. Molecular evidence on the evolutionary and biogeographical patterns of European cyprinids.

    Science.gov (United States)

    Zardoya, R; Doadrio, I

    1999-08-01

    The phylogenetic relationships of 106 European cyprinid taxa were determined based on the complete nucleotide sequence (1140 bp) of the mitochondrial cytochrome b gene. The molecular phylogeny was used (1) to revise the current systematics of European cyprinids, (2) to establish the phylogenetic utility of traditional morphological characters that are widely used in Cyprinidae systematics, and (3) to discuss alternative hypotheses on the biogeography of the family in Europe. The age of the major lineages within European cyprinids was tentatively estimated with a molecular clock and showed full agreement with the fossil record of the group. Moreover, the results provided unambiguous evidence for a close phylogenetic affinity of some Caucasian and Greek endemic cyprinid taxa (e.g., B. capito and B. brachycephalus and Leuciscus keadicus, Barbus graecus, and B. albanicus, respectively) to Iberian and North African, but not Central European, cyprinids. The existence of such unexpected phylogenetic relationships refutes the classical hypothesis on the biogeography of European cyprinids, which assumes a dispersal of the cyprinid fauna from central Europe to southern Europe and northern Africa during the Miocene (and, hence, predicts a close phylogenetic relationship of all Caucasian, Greek, Iberian, and North African cyprinids to central European taxa). Instead, the existence of a Mediterranean realm independent of the central European route seems plausible based on the molecular evidence. It is likely that the new biogeographical scenario proposed here might apply to other primary freshwater European animals with low dispersal abilities, including fish, amphibians, and invertebrates.

    Neospora caninum is an important intracellular protozoan parasite with an affinity to the central nervous system of many animals and a major causative agent of repeated abortions in cattle. In total, 45 muscle, liver, or spleen samples of brown bear sampled in different locations of Central Slovakia were examined by PCR. Genotyping of N. caninum was based on amplification of Nc-5 gene and ITS1 rRNA fragments and subsequent sequencing. Presence of N. caninum DNA was confirmed in 24.4% (11/45) of tested animals. The results obtained in study confirm the first molecular evidence of N. caninum DNA in European brown bear (Ursus arctos) in Slovakia. Copyright © 2013 Elsevier B.V. All rights reserved.

    The European epidemiology of MRSA is changing with the emergence of community-associated MRSA (CA-MRSA) and livestock-associated MRSA (LA-MRSA). In this study, we investigated the molecular epidemiology of MRSA during 2 years in 13 ICUs in France, Greece, Italy, Latvia, Luxemburg, Portugal, Slovenia and Spain. Surveillance cultures for MRSA from nose and wounds were obtained on admission and twice weekly from all patients admitted to an ICU for ≥3 days. The first MRSA isolate per patient was genotyped in a central laboratory by MLST, spa typing, agr typing and SCCmec (sub)typing. Risk factors for patients with an unknown history of MRSA colonization were identified. Overall, 14 390 ICU patients were screened, of whom 8519 stayed in an ICU for ≥3 days. Overall MRSA admission prevalence was 3.9% and ranged from 1.0% to 7.0% for individual ICUs. Overall MRSA acquisition rate was 2.5/1000 patient days at risk and ranged from 0.2 to 8/1000 patient days at risk per ICU. In total, 557 putative MRSA isolates were submitted to the central laboratory for typing, of which 511 (92%) were confirmed as MRSA. Each country had a distinct epidemiology, with ST8-IVc (UK-EMRSA-2/-6, USA500) being most prevalent, especially in France and Spain, and detected in ICUs in five of eight countries. Seventeen (3%) and three (70 years and hospitalization within 1 year prior to ICU admission. The molecular epidemiology of MRSA in 13 European ICUs in eight countries was homogeneous within, but heterogeneous between, countries. CA-MRSA and LA-MRSA genotypes and Panton-Valentine leucocidin-producing isolates were detected sporadically. © The Author 2015.

    In the present study, phylogenetic relationships of European and Far Eastern representatives of the genus Aspidogaster Baer, 1827 were analysed: A. conchicola Baer, 1827, A. limacoides Diesing, 1834, A. ijimai Kawamura, 1915 and A. chongqingensis Wei, Huang & Dai, 2001. Based on ITS1-5.8S-ITS2 rDNA sequence data, an obvious differentiation was seen between specimens of A. limacoides s ensu stricto from the European part of Russia and A. limacoides sensu Chen et al., 2010 from China (13.7%); the latter parasites were recognized as A. chongqingensis. Aspidogaster chongqingensis was more closely related to A. ijimai than to A. limacoides s. str. Specimens of A. ijimai from the Amur River, Khanka Lake (Russian Far East) and China were grouped into a single clade with low intra specific molecular differentiation (d = 0-0.3%). Specimens of A. conchicola from the European part of Russia, the Russian Far East and China also formed a single distinct clade. Genetic differentiation between European and Chinese samples of this species was two times lower (d = 0.45%) than between Russian Far East and European or Chinese samples (d = 0.96%), suggesting a long-term separate existence of A. conchicola in the Russian Far East.

  15. Teaching European Studies: A Blended Learning Approach

    2011-12-01

    Full Text Available This paper will be looking into the teaching method developed by the Institute for European Studies in Brussels, combining an e-learning tool- the E-modules- with face-to-face training sessions and webinars. The main aim is to analyse the three different components of this “blended learning” pedagogical approach, as well as the way they complement each other and to address a few of the challenges that have emerged from the experience of working with them so far. The E-modules are an e-learning platform that has been designed with the purpose of offering a structured and interactive way of learning how the European Union functions. The face-to-face training component currently takes the form of three days in-house seminars, covering in an intensive manner the most important areas of the curriculum. The lectures are held by a mix of academics and practitioners, hereby ensuring a balanced approach, in which theory and practice come together to facilitate the learning experience. The third element of the “blended learning” method is placed in-between online and face-to-face learning: interactive seminars and debates are held online, giving the participants the chance to deepen their knowledge in certain fields of interest and to discuss the content of the course with specialists and among themselves. The mixture of delivery and interaction methods was chosen in order to accommodate a large variety of target groups, ranging from students to professionals working with EU-related issues, with different backgrounds and geographical origins. One of the main challenges is to use each medium for the functionalities it is best designed for and to ensure that the various pieces of the pedagogical puzzle fit together perfectly, while allowing the learners the flexibility that had initially directed them towards “blended learning” instead of a classical classroom approach.

    2016-01-01

    We present a phylogenetic investigation of the Northern Clade, the major monophyletic clade within the freshwater fish family Cobitidae, one of the most prominent families of freshwater fishes found in Asian and European waters. Phylogenetic reconstructions based on the cytochrome b and RAG-1 genes show the genera Microcobitis, Sabanejewia, Koreocobitis and Kichulchoia as monophyletic groups. These reconstructions also show a Cobitis sensu lato and a Misgurnus sensu lato group. The Cobitis sensu lato group includes all species of Cobitis, Iksookimia, Niwaella and Kichulchoia, while the Misgurnus sensu lato group includes Misgurnus, Paramisgurnus and Koreocobitis. Although the monophyly of both the Cobitis sensu lato and Misgurnus sensu lato groups is supported, relationships within the groups are incongruent with current generic definitions. The absence of monophyly of most genera included in the Cobitis sensu lato group (Cobitis, Iksookimia and Niwaella) or their low genetic differentiation (Kichuchoia) supports their consideration as synonyms of Cobitis. Molecular phylogenies indicate that the Asian species of Misgurnus experienced a mitochondrial introgression from a lineage of Cobitis. We also find two nuclear haplotypes in the same Cobitis species from the Adriatic area that, in the absence of morphological differentiation, may indicate molecular introgression. Most lineages within the Northern Clade consist of species found in East Asia. However, some lineages also contain species from Europe and Asia Minor. The phylogenetic relationships presented here are consistent with previous studies suggesting an East Asian origin of the Northern Clade. According to the current distributions and phylogenetic relationships of the Misgurnus sensu lato and Cobitis clade lineages, particularly of M. fossilis and C. melanoleuca, the range expansion of East Asian species into Europe was most likely via Siberia into Northern and Central Europe. Phylogenetic analyses also show

    2009-01-01

    Full Text Available Breast cancer in African-American (AA women occurs at an earlier age than in European-American (EA women and is more likely to have aggressive features associated with poorer prognosis, such as high-grade and negative estrogen receptor (ER status. The mechanisms underlying these differences are unknown. To address this, we conducted a case-control study to evaluate risk factors for high-grade ER- disease in both AA and EA women. With the onset of the Health Insurance Portability and Accountability Act of 1996, creative measures were needed to adapt case ascertainment and contact procedures to this new environment of patient privacy. In this paper, we report on our approach to establishing a multicenter study of breast cancer in New York and New Jersey, provide preliminary distributions of demographic and pathologic characteristics among case and control participants by race, and contrast participation rates by approaches to case ascertainment, with discussion of strengths and weaknesses.

    With the introduction of Nintendo video-games on a large scale, reports of children having seizures while playing suggested a possible specific, provocative factor. Although 50% of the photosensitive patients are also sensitive to a 50-Hz television, nonphotosensitive patients with a history of video-game seizures were described as well. The question arises whether this is a mere coincidence, provoked by fatigue and stress, is related to the reaction to the television screen itself, or depends on the movement and color of the pictures of this specific game. A European study was performed in four countries and five sites. All patients were selected because of a history of television, video- or computer-game seizures, with a history of sun-light-, discotheque-, or black and white pattern-evoked seizures, or were already known to be sensitive to intermittent photic stimulation. A total of 387 patients were investigated; 220 (75%) were female and 214 (55%) of those were Super Mario World and a standard relatively nonprovocative TV program, both on a 50- and 100-Hz television. Regardless of the distance, Super Mario World proved to be more provocative than the standard program (Wilcoxon, p computer-game seizure, were significantly more sensitive to pattern and to the 50-Hz television (chi square, p Super Mario, compared with the standard program (Wilcoxon, p = 0.001) and more sensitive with playing versus viewing (p = 0.016). Of the patients who were referred because of seizures in front of the television, or evoked by a video- or computer game, 14% proved not to be photosensitive. Although no difference in age or use of medication was found, twice as many men were found in this nonphotosensitive group.

    2010-08-14

    The Joint United States - European Union Theoretical and Practical Course on Molecular Approaches for in situ Biodegradation was held May 24 through June 7 at The University of Oklahoma. Twenty-four graduate and postgraduate students from both the United States and the European Union attended the course. Nine states and ten European countries were represented. Students were assigned living quarters and laboratory partners to maximize interactions between US and EU participants as well as to mix people with different technical backgrounds together. The students used the latest methods in molecular biology to characterize beneficial microorganisms and genes involved in the biodegradation of pollutants at a nearby landfill as well as an active hydrocarbon-producing site, part of which is undergoing bioremediation. Seminars by distinguished scientists were organized to expose the students to the breadth of the environmental field, including field assay and engineering applications, laboratory scale bioreactors, microbiology, genetics, regulation, pathway analysis, design of recombinant bacteria, and application of the associated techniques to the field. Lectures were given by various OU faculty on the principles behind the techniques to be used in the laboratory. These lectures included troubleshooting hints and encouraged questions and comments from the audience. The laboratory experiments covered chemical, microbiological, and molecular genetic analyses of soils; bioavailability of contaminants; enrichment cultures; gene probing; PCR amplification of known genes and gene families; identification of microbes based traditional and nontraditional approaches, nutritional capabilities, and 16S rRNA sequence; mRNA detection; and enzyme assays. Field trips were made to the USGS landfill field sampling site, and to the Tall Grass Prairie Preserve, a Nature Conservancy site which also featured long-term studies of bioremediation of crude oil and brine spills by one of the

    Circumstellar envelopes (CEs) around evolved stars are an active site for the production of molecules. After evolving through the Asymptotic Giant Branch (AGB), proto-planetary nebula (PPN), to planetary nebula (PN) phases, CEs ultimately merge with the interstellar medium (ISM). The study of molecules in PNe, therefore, is essential to understanding the transition from stellar to interstellar materials. So far, over 20 molecular species have been discovered in PNe. The molecular composition of PNe is rather different from those of AGB and PPNe, suggesting that the molecules synthesized in PN progenitors have been heavily processed by strong ultraviolet radiation from the central star. Intriguingly, fullerenes and complex organic compounds having aromatic and aliphatic structures can be rapidly formed and largely survive during the PPN/PN evolution. The similar molecular compositions in PNe and diffuse clouds as well as the detection of C60 + in the ISM reinforce the view that the mass-loss from PNe can significantly enrich the ISM with molecular species, some of which may be responsible for the diffuse interstellar bands. In this contribution, I briefly summarize some recent observations of molecules in PNe, with emphasis on their implications on circumstellar chemistry.

    This article is a comparative analysis of the European Values Study (EVS) and the European Social Survey (ESS) using five analytical dimensions: agents, ideas, methods, institutions and context. From the outset, both surveys were closely connected to national and European social science...... institutions, had ties to the EU, and used survey techniques to address urgent contemporary political and social problems. Despite their similarities, the surveys represent two rather different constellations of social science knowledge production. The EVS emerged from a coalition of Catholic-oriented agents...... from a diverse set of social institutions driven by political and ethical concerns about social change in the 1960s and 1970s.

    The phenomena observed in young stellar objects (YSO), circumstellar regions and extra-galactic nuclei show some similarity in their morphology, dynamical and physical processes, though they may differ in scale and energy. The European Workshop on Astronomical Molecules 2004 gave astronomers a unique opportunity to discuss the links among the observational results and to generate common interpretations of the phenomena in stars and galaxies, using the available diagnostic tools such as masers and dense molecular gas. Their theoretical understanding involves physics, numerical simulations and chemistry. Including a dozen introductory reviews, topics of papers in this book also cover: maser and dense gas diagnostics and related phenomena, evolution of circumstellar regions around protostars, evolution of circumnuclear regions of active galaxies, diagnostics of the circumnuclear gas in stars and galactic nuclei. This book summarizes our present knowledge in these topics, highlights major problems to be addressed...

Should academics engage with the public? What are the most effective outreach strategies? And what are the implications for universities and departments? The article argues that engaging with the public should be considered an integral part for academics working on topics that relate to the European Union or European politics. The article has a theoretical and a practical dimension. The first part of the paper deals with the nature of public engagement, explaining why it is an important issue and how it differs from the mainstream understanding of public engagement. The practical part of the paper presents the idea of building an online presence through which academics can engage with the public debate both during periods of low issue salience and high issue salience.

M. plutonius is one of the major bacterial pathogens of honeybee broods and is the causative agent of European Foulbrood disease (EFB. Larvae from samples suspected of infection were collected from different apiaries and homogenized in phosphate buffered saline (PBS. Bacteria were isolated on MYPGP agar medium. Two bacterial isolates, ksuMP7 and ksuMP9 (16S rRNA GenBank accession numbers, KX417565 and KX417566, respectively, were subjected to molecular identification using M. plutonius -specific primers, a BLAST sequence analysis revealed that the two isolates were M. plutonius with more than 98% sequence identity. The molecular detection of M. plutonius from honeybee is the first recorded incidence of this pathogen in Saudi Arabia. This study emphasizes the need for official authorities to take immediate steps toward treating and limiting the spread of this disease throughout the country.

    A molecular beam photoionization apparatus which combines the advantages of both the molecular beam method with photoionization mass spectrometry has been designed and constructed for carrying out some unique photoionization experiments. Rotational cooling during the supersonic expansion has resulted in high resolution photoionization efficiency curves for NO, ICl, C/sub 2/H/sub 2/ and CH/sub 3/I. The analysis of these spectra has yielded ionization potentials for these molecules to an accuracy of +- 3 MeV. Detailed autoionization structures were also resolved. This allows the investigation of the selection rules for autoionization, and the identification of the Rydberg series which converge to the excited states of the molecular ions. The degree of relaxation for thermally populated excited states has been examined using NO and ICl as examples. As a result of adiabatic cooling, a small percentage of dimers is also formed during the expansion. The photoionization efficiency curves for (NO)/sub 2/, ArICl, Ar/sub 2/, Kr/sub 2/ and Xe/sub 2/ have been obtained near the thresholds. Using the known dissociation energies of the (NO)/sub 2/, Ar/sub 2/, Kr/sub 2/ and Xe/sub 2/ van der Waals molecules, the corresponding dissociation energies for NO-NO/sup +/, Ar/sub 2//sup +/, Kr/sub 2//sup +/, and Xe/sub 2//sup +/ have been determined. The ionization mechanisms for this class of molecules are examined and discussed.

    Patients increasingly use social media to communicate. Their stories could support quality improvements in participatory health care and could support patient-centered care. Active use of social media by health care institutions could also speed up communication and information provision to patients and their families, thus increasing quality even more. Hospitals seem to be becoming aware of the benefits social media could offer. Data from the United States show that hospitals increasingly use social media, but it is unknown whether and how Western European hospitals use social media. To identify to what extent Western European hospitals use social media. In this longitudinal study, we explored the use of social media by hospitals in 12 Western European countries through an Internet search. We collected data for each country during the following three time periods: April to August 2009, August to December 2010, and April to July 2011. We included 873 hospitals from 12 Western European countries, of which 732 were general hospitals and 141 were university hospitals. The number of included hospitals per country ranged from 6 in Luxembourg to 347 in Germany. We found hospitals using social media in all countries. The use of social media increased significantly over time, especially for YouTube (n = 19, 2% to n = 172, 19.7%), LinkedIn (n =179, 20.5% to n = 278, 31.8%), and Facebook (n = 85, 10% to n = 585, 67.0%). Differences in social media usage between the included countries were significant. Social media awareness in Western European hospitals is growing, as well as its use. Social media usage differs significantly between countries. Except for the Netherlands and the United Kingdom, the group of hospitals that is using social media remains small. Usage of LinkedIn for recruitment shows the awareness of the potential of social media. Future research is needed to investigate how social media lead to improved health care.

    To determine fusidic acid resistance rates (MICs of > or = 2 mg/L) and the prevalence of fusidic acid resistance mechanisms among Staphylococcus spp. collected from European countries (2008). Staphylococcal isolates (3134) collected from Europe were tested by CLSI broth microdilution. Isolates displaying a fusidic acid MIC of > or = 2 mg/L (non-susceptible; European Committee on Antimicrobial Susceptibility Testing breakpoint) were tested for fusB, fusC and fusD. The fusidic acid target sites fusA and fusE were then sequenced, and a method for the detection of the fusA mutation L461K was developed. Selected isolates were typed by PFGE. Fusidic acid resistance rates were higher among coagulase-negative staphylococci (CoNS) compared with Staphylococcus aureus. Acquired fusidic acid resistance genes were detected in 64.9% of the samples; fusB and fusC were detected among 10.1% and 16.9% of the fusidic acid-resistant S. aureus and among 26.5% and 11.3% of the CoNS, respectively. Ireland and Greece showed the highest S. aureus fusidic acid resistance levels, with low rates of acquired fusidic acid resistance genes. Isolates from these countries displayed MIC values of > or = 512 mg/L, the presence of the elongation factor G L461K alteration and clonal occurrences. Low S. aureus fusidic acid resistance rates (1%-3%) were observed in Germany, Israel, Italy, Poland, Spain and Sweden. Isolates with MIC values < or = 64 mg/L showed a great diversity of acquired fusidic acid resistance mechanisms. Acquired fusidic acid resistance genes were detected in the majority of fusidic acid-resistant isolates from Belgium, France, Switzerland, Sweden, Italy and the UK (72.2%-92.9%), and were slightly less frequent in Germany, Spain and Israel (61.3%-66.7%). This contemporary study showed that acquired fusidic acid resistance genes were prevalent among fusidic acid-non-susceptible European staphylococcal isolates.

    Full Text Available Insulin plays an important role in maintaining the blood glucose level of the body. The β-cells of pancreas produce insulin in the form of precursor that is preproinsulin. The gene of preproinsulin provides an interesting system for addressing question related to molecular evolution. Recombinant DNA technology has made it possible to isolate and sequence the chromosomal genes coding for unique protein products. Although preproinsulin of various organism has been isolated and cloned, but there is no report from buffalo (Bubalus bubalis that is our major livestock. The genomic DNA of buffalo was isolated using Laura-Lee-Boodram method. The part of preproinsulin gene (596bp and 520bp using BPPI-UPS and bpiful_F as forward and BC1-C as reverse primer was amplified. Cloning of amplified fragments of gene were performed in pCR 2.1 vector. Positive clones were screened on the basis of blue white selection. The band obtained on 596bp and 520bp after colony PCR confirmed the successful cloning of preproinsulin gene in pCR 2.1 vector.

    Full Text Available Purpose – Our paper aims at analyzing how different European countries cope with the European Energy Policy, which proposes a set of measures (free energy market, smart meters, energy certificates to improve energy utilization and management in Europe.Design/methodology/approach – The paper first reports the general vision, regulations and goals set up by Europe to implement the European Energy Policy. Later on, it performs an analysis of how some European countries are coping with the goals, with financial, legal, economical and regulatory measures. Finally, the paper draws a comparison between the countries to present a view on how Europe is responding to the emerging energy emergency of the modern world.Findings – Our analysis on different use cases (countries showed that European countries are converging to a common energy policy, even though some countries appear to be later than others In particular, Southern European countries were slowed down by the world financial and economical crisis. Still, it appears that contingency plans were put into action, and Europe as a whole is proceeding steadily towards the common vision.Research limitations/implications – European countries are applying yet more cuts to financing green technologies, and it is not possible to predict clearly how each country will evolve its support to the European energy policy.Practical implications – Different countries applied the concepts and measures in different ways. The implementation of the European energy policy has to cope with the resulting plethora of regulations, and a company proposing enhancement regarding energy management still has to possess robust knowledge of the single country, before being able to export experience and know-how between European countries.Originality/Value – Even though a few surveys on energy measures in Europe are already part of the state-of-the-art, organic analysis diagonal to the different topics of the European

    2008-08-01

    The aim of this study was to determine the prevalence of burnout, and of associated factors, amongst family doctors (FDs) in European countries. Methodology. A cross-sectional survey of FDs was conducted using a custom-designed and validated questionnaire which incorporated the Maslach Burnout Inventory Human Services Survey (MBI-HSS) as well as questions about demographic factors, working experience, health, lifestyle and job satisfaction. MBI-HSS scores were analysed in the three dimensions of emotional exhaustion (EE), depersonalization (DP) and personal accomplishment (PA). Almost 3500 questionnaires were distributed in 12 European countries, and 1393 were returned to give a response rate of 41%. In terms of burnout, 43% of respondents scored high for EE burnout, 35% for DP and 32% for PA, with 12% scoring high burnout in all three dimensions. Just over one-third of doctors did not score high for burnout in any dimension. High burnout was found to be strongly associated with several of the variables under study, especially those relative to respondents' country of residence and European region, job satisfaction, intention to change job, sick leave utilization, the (ab)use of alcohol, tobacco and psychotropic medication, younger age and male sex. Burnout seems to be a common problem in FDs across Europe and is associated with personal and workload indicators, and especially job satisfaction, intention to change job and the (ab)use of alcohol, tobacco and medication. The study questionnaire appears to be a valid tool to measure burnout in FDs. Recommendations for employment conditions of FDs and future research are made, and suggestions for improving the instrument are listed.

    Present is the role of formal education on natural disasters in Europe. To ensure a uniform overview, the study used secondary-school geography textbooks from the collection of textbooks at the Georg Eckert Institute for International Textbook Research in Braunschweig, Germany. Altogether, more than 160 textbooks from 36 European countries were examined in order to investigate how much their content (pages, text, figures) is related to natural-disasters topics, and to find out which types of hazards are presented more often. In the research it was also analyzed which disaster events are frequently used as an example.

    Reproduction in captivity is a key study issue in Anguilla anguilla as a possible solution for its dwindling population. Understanding the mechanisms controlling the production of ribosomal building blocks during artificially induced oocyte maturation could be particularly interesting. Transcription levels of ribosomal biogenesis associated genes could be used as markers to monitor oogenesis. Eels from the Albufera Lagoon were injected with carp pituitary extract for 15weeks and ovaries in previtellogenic (PV) stage (non-injected), in early-, mid-, late-vitellogenesis (EV, MV, LV), as well as in migratory nucleus stage (MN) were analysed. 5S rRNA and related genes were highly transcribed in ovaries with PV oocytes. As oocytes developed, transcriptional levels of genes related to 5S rRNA production (gtf3a), accumulation (gtf3a, 42sp43) and nucleocytoplasmic transport (rpl5, rpl11) and the 5S/18S rRNA index decreased (PV>EV>MV>LV>MN). On the contrary, 18S rRNA was at its highest at MN stage while ubtf1 in charge of activating RNA-polymerase I and synthesising 18S rRNA behaved as 5S related genes. Individuals that did not respond (NR) to the treatment showed 5S/18S index values similar to PV females, while studied genes showed EV/LV-like transcription levels. Therefore, NR females fail to express the largest rRNAs, which could thus be taken as markers of successful vitellogenesis progression. In conclusion, we have proved that the transcriptional dynamics of ribosomal genes provides useful tools to characterize induced ovarian development in European eels. In the future, such markers should be studied as putative indicators of response to hormonal treatments and of the quality of obtained eel oocytes. Copyright © 2017. Published by Elsevier Inc.

    The European mink Mustela lutreola is regarded as one of the most endangered mammals in the world. We chose to characterize microsatellite loci in order to investigate the pattern of decline of this species. We used primer pairs developed for a related species Mustela vison to genotype individual of Mustela lutreola. Out of 19 primer pairs used 8 were useful for our purpose. The conservation of primer sequence point out the problem of neutrality of some microsatellite loci as this conservation could be related to strong selection pressure on those loci. Finally we present the first data allowing an estimation of heterozygosity of French population of European mink.

  20. Ethics teaching in European veterinary schools: a qualitative case study.

    2014-12-13

    Veterinary ethics is recognised as a relevant topic in the undergraduate veterinary curriculum. However, there appears to be no widely agreed view on which contents are best suited for veterinary ethics teaching and there is limited information on the teaching approaches adopted by veterinary schools. This paper provides an inside perspective on the diversity of veterinary ethics teaching topics, based on an in-depth analysis of three European veterinary schools: Copenhagen, Lisbon and Nottingham. The case study approach integrated information from the analysis of syllabi contents and interviews with educators (curricular year 2010-2011). These results show that the curriculum of veterinary ethics is multidimensional and can combine a wide range of scientific, regulatory, professional and philosophical subjects, some of which may not be explicitly set out in the course descriptors. A conceptual model for veterinary ethics teaching is proposed comprising prominent topics included within four overarching concepts: animal welfare science, laws/regulations, professionalism, and theories/concepts. It is intended that this work should inform future curriculum development of veterinary ethics in European schools and assist ethical deliberation in veterinary practice.

    The second order nonlinear optical processes of second harmonic generation and sum frequency generation are powerful new probes of surfaces. They possess unusual surface sensitivity due to the symmetry properties of the nonlinear susceptibility. In particular, infrared-visible sum frequency generation (SFG) can obtain the vibrational spectrum of sub-monolayer coverages of molecules. In this thesis, we explore the unique information that can be obtained from SFG. We take advantage of the sensitivity of SFG to the conformation of alkane chains to study the interaction between adsorbed liquid crystal molecules and surfactant treated surfaces. The sign of the SFG susceptibility depends on the sign of the molecular polarizability and the orientation, up or down, of the molecule. We experimentally determine the sign of the susceptibility and use it to determine the absolute orientation to obtain the sign of the molecular polarizability and show that this quantity contains important information about the dynamics of molecular charge distributions. Finally, we study the vibrational spectra and the molecular orientation at the pure liquid/vapor interface of methanol and water and present the most detailed evidence yet obtained for the structure of the pure water surface. 32 refs., 4 figs., 2 tabs.

    The 19th Europhysics Sectional Conference on the Atomic and Molecular Physics of Ionized Gases (ESCAMPIG-2008) took place in Granada (Spain) from 15 to 19 July 2008. The conference was mainly organized by the Spanish National Research Council (CSIC), with the collaboration and support of the University of Córdoba (UCO) and the Research Center for Energy, Environment and Technology (CIEMAT). It is already 35 years since the first ESCAMPIG in 1973. The first editions of ESCAMPIG were in consecutive years (1973 and 1974) but later on it became a biennial conference of the European Physical Society (EPS) initially focusing on the collisional and radiative atomic and molecular processes in low temperature plasmas. The successive ESCAMPIGs took place in Bratislava in 1976 (3rd), Essen in 1978 (4th), Dubrovnik in 1980 (5th) and so on until the last one organized in Granada in 2008 (19th), the first ESCAMPIG in Spain. A number of changes have taken place in the Granada edition of ESCAMPIG. First, the previous six topics that have remained unchanged for almost two decades (since 1990) have now been updated to become twelve new topics which, in the opinion of the International Scientific Committee (ISC), will enhance the opportunity for discussions and communication of new findings and developments in the field of low temperature plasmas. The new list of topics for ESCAMPIG is: • Atomic and molecular processes in plasmas • Transport phenomena, particle velocity distribution function • Physical basis of plasma chemistry • Plasma surface interaction (boundary layers, sheath, surface processes) • Plasma diagnostics • Plasma and dicharges theory and simulation • Self-organization in plasmas, dusty plasmas • Upper atmospheric plasmas and space plasmas • Low pressure plasma sources • High pressure plasma sources • Plasmas and gas flows • Laser produced plasmas Secondly, a new prize has been created, the `William Crookes' prize in Plasma Physics to be

    Full Text Available Smart grid is a power system consisting of many transmission and distribution systems subjected to an automation which are efficient, reliable and coordinated with each other. As a nature friendly technology, Smart grid come into prominence due to the increasing energy consumption and limited renewable energy sources around the world. In the near future, the use of renewable energy sources is not expected to grow rapidly; but the transmission and distribution systems will be enhanced by Smart grid technologies. Considering these significant benefits, the studies have been increased on Smart grid technologies to meet the energy requirement in each country. Herewith, the aim of this study is to analyse the scientific studies in developed European countries such as Italy, Germany, United Kingdom, France and Spain to find out the increment rate of the importance devoted to the Smart grid technologies in academicals manner. The scientific researches on Smart grid are achieved from the Web of Science database and the statistical analysis have been made by utilizing proper SQL queries in combination with Excel Power Pivot for these countries. The correlation between the scientific studies on smart grid and the virtual smart grid applications are also outlined for each selected country.

    To characterize meal patterns across ten European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) calibration study. Cross-sectional study utilizing dietary data collected through a standardized 24 h diet recall during 1995-2000. Eleven predefined intake occasions across a 24 h period were assessed during the interview. In the present descriptive report, meal patterns were analysed in terms of daily number of intake occasions, the proportion reporting each intake occasion and the energy contributions from each intake occasion. Twenty-seven centres across ten European countries. Women (64 %) and men (36 %) aged 35-74 years (n 36 020). Pronounced differences in meal patterns emerged both across centres within the same country and across different countries, with a trend for fewer intake occasions per day in Mediterranean countries compared with central and northern Europe. Differences were also found for daily energy intake provided by lunch, with 38-43 % for women and 41-45 % for men within Mediterranean countries compared with 16-27 % for women and 20-26 % for men in central and northern European countries. Likewise, a south-north gradient was found for daily energy intake from snacks, with 13-20 % (women) and 10-17 % (men) in Mediterranean countries compared with 24-34 % (women) and 23-35 % (men) in central/northern Europe. We found distinct differences in meal patterns with marked diversity for intake frequency and lunch and snack consumption between Mediterranean and central/northern European countries. Monitoring of meal patterns across various cultures and populations could provide critical context to the research efforts to characterize relationships between dietary intake and health.

  13. Spaceflight studies of tropisms in the European Modular Cultivation System

    Science.gov (United States)

    Kiss, J. Z.; Correll, M. J.; Edelmann, R. E.

    Phototropism and gravitropism play key roles in the oriented growth of roots in flowering plants. In blue or white light, roots exhibit negative phototropism, but red light induces positive phototropism in Arabidopsis roots. The blue-light response is controlled by the phototropins while the red-light response is mediated by the phytochrome family of photoreceptors. In order to better characterize root phototropism, we plan to perform experiments in microgravity so that this tropism can be more effectively studied without the interactions with the gravity response. Our experiments are to be performed on the European Modular Cultivation System (EMCS), which provides an incubator, lighting system, and high resolution video that are on a centrifuge palette. These experiments will be performed at μ g, 1g (control) and fractional g-levels. In order to ensure success of this mission on the International Space Station (ISS), we have been performing ground-based studies on growth, phototropism, and gravitropism in experimental unique equipment (EUE) that was designed for our experiments that will use Arabidopsis seedlings. Currently, the EMCS and our EUE are scheduled for launch on space shuttle mission STS-121. This project should provide insight into how the blue-light and red-light signaling systems interact with each other, and also with the gravisensing system.

    This cross-sectional study assesses the relationship between consumption frequencies of food items and high-sensitivity C-reactive protein (hs-CRP) in European children. Out of the baseline sample (N = 16.228) of the IDEFICS study, 6.403 children (1.315 boys aged 2 to food frequency questionnaire. Logistic regression adjusted for body mass index z-score, education of the mother, breast-feeding and self-reported hours of physical activity in a sport club per week was conducted. Mean frequency intake of raw vegetable was lower in boys (p = 0.022 in young and p = 0.020 in old) and older girls (p = 0.026) with high hs-CRP concentration, while in younger girls (p = 0.008) the same occurred with the cooked vegetables. The probability of having higher hs-CRP concentration was significantly associated with having low consumption frequency of vegetables (p = 0.004 in older boys, raw vegetables; and p = 0.0032 in younger girls, cooked vegetables). Also, honey/jam intake decreased the probability of having higher concentration of hs-CRP, whereas soft drinks with sugar, mayonnaise and cereals milled increased this probability. Out of all food items associated with hs-CRP, frequency intake of vegetables presented more associations across all the analysis. Findings suggest that a high-frequency intake of vegetables is inversely related to an inflammatory status in children. More studies are needed to assess the association between diet and inflammation.

    Full Text Available For several years, the European Union (EU has been increasing its international presence and moving into the role of a global security actor. To support the goal of greater crisis management capabilities, European security integration (ESI has been deepening. This article therefore examines an Ell operation - the European Union Training Mission in Mali (EUTM Mali - with the aim of gauging the success of the EU's efforts at ESI. To determine the success of EUTM Mali and thus of ESI, three propositions are examined: if EUTM Mali is a security operation showing successful security integration, there will be evidence of (i broad participation, (ii financial burden-sharing and (iii the successful incorporation of troops and equipment. The first and third propositions are supported whereas the second does not receive as much support. Overall, EUTM Mali shows considerable success and bodes well for further ESI.

    program by 16 invited lectures, 7 selected hot topics, and 191 poster presentations. The largest number of contributed papers was submitted in Topic 5: Plasma diagnostics (37). The workshop topics were addressed by 10 invited lectures, 5 oral presentations and 7 posters. A post-conference workshop with 5 invited lectures was organized, dealing with the data needs for modeling of plasma sources of light. ESCAMPIG XX was attended by 185 scientists from 31 countries. Of the participants, 30% were PhD students (55). The list includes scientists from the USA, Japan, Australia, Mexico and other non-European countries, which indicates the truly international status of the conference. We would like to thank the authors for their efforts in preparing stimulating lectures and interesting articles for the readers of PSST, and the scientific community dealing with ionized gases, plasma sources and atomic, molecular and chemical physics of low-temperature plasmas for continued interest in the field of ESCAMPIG. We would like to thank the organizers of all previous ESCAMPIG conferences for setting the standards for organization and, in particular, the organizers of ESCAMPIG XVIII and XIX for their direct help and insight. Finally the International Scientific Committee and its chairman in particular have worked hard to select the best possible program and to keep us in line with almost 40 years of tradition and standards of the conference. Most importantly this has been the 20th conference. The quality of new papers shows maturity and new vistas in the field that has produced so much fundamental understanding of complex, non-equilibrium, even nonlinear plasmas. At the same time the field has led to some of the key technologies of modern civilization and has shown that responsible science that pays attention to its societal benefits should have no fear for its future. All critical issues studied today were presented at the meeting and only a small part is represented here. For example

    Surveillance was conducted for the occurrence of protozoan parasites of the genus Cryptosporidium in European hedgehogs (Erinaceus europaeus) in Great Britain. In total, 108 voided faecal samples were collected from hedgehogs newly admitted to eight wildlife casualty treatment and rehabilitation centres. Terminal large intestinal (LI) contents from three hedgehog carcasses were also analysed. Information on host and location variables, including faecal appearance, body weight, and apparent health status, was compiled. Polymerase Chain Reaction (PCR) targeting the 18S ribosomal RNA gene, confirmed by sequencing, revealed an 8% (9/111) occurrence of Cryptosporidium parvum in faeces or LI contents, with no significant association between the host or location variables and infection. Archived small intestinal (SI) tissue from a hedgehog with histological evidence of cryptosporidiosis was also positive for C. parvum by PCR and sequence analysis of the 18S rRNA gene. No other Cryptosporidium species were detected. PCR and sequencing of the glycoprotein 60 gene identified three known zoonotic C. parvum subtypes not previously found in hedgehogs: IIdA17G1 (n=4), IIdA19G1 (n=1) and IIdA24G1 (n=1). These subtypes are also known to infect livestock. Another faecal sample contained C. parvum IIcA5G3j which has been found previously in hedgehogs, and for which there is one published report in a human, but is not known to affect livestock. The presence of zoonotic subtypes of C. parvum in British hedgehogs highlights a potential public health concern. Further research is needed to better understand the epidemiology and potential impacts of Cryptosporidium infection in hedgehogs. Copyright © 2015 Elsevier B.V. All rights reserved.

    Environmental DNA and culture-based analyses have suggested that fungi are present in low diversity and in low abundance in many marine environments, especially in the upper water column. Here, we use a dual approach involving high-throughput diversity tag sequencing from both DNA and RNA templates and fluorescent cell counts to evaluate the diversity and relative abundance of fungi across marine samples taken from six European near-shore sites. We removed very rare fungal operational taxonomic units (OTUs) selecting only OTUs recovered from multiple samples for a detailed analysis. This approach identified a set of 71 fungal 'OTU clusters' that account for 66% of all the sequences assigned to the Fungi. Phylogenetic analyses demonstrated that this diversity includes a significant number of chytrid-like lineages that had not been previously described, indicating that the marine environment encompasses a number of zoosporic fungi that are new to taxonomic inventories. Using the sequence datasets, we identified cases where fungal OTUs were sampled across multiple geographical sites and between different sampling depths. This was especially clear in one relatively abundant and diverse phylogroup tentatively named Novel Chytrid-Like-Clade 1 (NCLC1). For comparison, a subset of the water column samples was also investigated using fluorescent microscopy to examine the abundance of eukaryotes with chitin cell walls. Comparisons of relative abundance of RNA-derived fungal tag sequences and chitin cell-wall counts demonstrate that fungi constitute a low fraction of the eukaryotic community in these water column samples. Taken together, these results demonstrate the phylogenetic position and environmental distribution of 71 lineages, improving our understanding of the diversity and abundance of fungi in marine environments. © 2015 The Authors.

    Among 8000-9000 species of Cnidaria, only several dozens of species of Hydrozoa have been found in the fresh water. Hydra is such a fresh water polyp and has been used as a good material for research in developmental biology, regeneration and pattern formation. Although the genus Hydra has only a few ten species, its distribution is cosmopolitan. The phylogenetic relationship between hydra species is fascinating from the aspect of evolutionary biology and biogeography. However, only a few molecular phylogenetic studies have been reported on hydra. Therefore, we conducted a molecular phylogenetic study of the genus Hydra based on mitochondrial and nuclear nucleotide sequences using a hydra collection that has been kept in the National Institute of Genetics (NIG) of Japan. The results support the idea that four species groups comprise the genus Hydra. Within the viridissima group (green hydra) and braueri group, genetic distances between strains were relatively large. In contrast, genetic distances between strains among the vulgaris and oligactis groups were small irrespective of their geographic distribution. The vulgaris group strains were classified at least (as far as our investigated samples) into three sub-groups, vulgaris sub-group, carnea sub-group, and H. sp. (K5 and K6) sub-group. All of the vulgaris sub-group and H. sp. (K5 and K6) sub-group strains were collected in Eurasia. The carnea sub-group strains in NIG collection were all collected in North America. A few newly collected samples in Japan, however, suggested belonging to the carnea sub-group according to the molecular phylogenic analysis. This suggests a trans-Pacific distribution of the carnea sub-group hydra. Copyright © 2010 Elsevier B.V. All rights reserved.

    We present an analytic and stochastic simulation study of a molecular engine working with a flux of particles as a turbine. We focus on the physical observables of velocity, flux, power, and efficiency. The control parameters are the external conservative force and the particle densities. We revise a simpler previous study by using a more realistic model containing multiple equidistant vanes complemented by stochastic simulations of the particles and the turbine. Here we show that the effect of the thermal fluctuations into the flux and the efficiency of these nanometric devices are relevant to the working scale of the system. The stochastic simulations of the Brownian motion of the particles and turbine support the simplified analytical calculations performed.

    Full Text Available Molecular dynamics simulations were performed to study thermodynamics and structural properties of expanded caesium fluid. Internal pressure, radial distribution functions (RDFs, coordination numbers and diffusion coefficients have been calculated at temperature range 700–1600 K and pressure range 100–800 bar. We used the internal pressure to predict the metal–non-metal transition occurrence region. RDFs were calculated at wide ranges of temperature and pressure. The coordination numbers decrease and positions of the first peak of RDFs slightly increase as the temperature increases and pressure decreases. The calculated self-diffusion coefficients at various temperatures and pressures show no distinct boundary between Cs metallic fluid and its expanded fluid where it continuously increases with temperature.

  16. Thermal transpiration: A molecular dynamics study

    T, Joe Francis [Computational Nanotechnology Laboratory, School of Nano Science and Technology, National Institute of Technology Calicut, Kozhikode (India); Sathian, Sarith P. [Department of Applied Mechanics, Indian Institute of Technology Madras, Chennai (India)

    Thermal transpiration is a phenomenon where fluid molecules move from the cold end towards the hot end of a channel under the influence of longitudinal temperature gradient alone. Although the phenomenon of thermal transpiration is observed at rarefied gas conditions in macro systems, the phenomenon can occur at atmospheric pressure if the characteristic dimensions of the channel is less than 100 nm. The flow through these nanosized channels is characterized by the free molecular flow regimes and continuum theory is inadequate to describe the flow. Thus a non-continuum method like molecular dynamics (MD) is necessary to study such phenomenon. In the present work, MD simulations were carried out to investigate the occurance of thermal transpiration in copper and platinum nanochannels at atmospheric pressure conditions. The mean pressure of argon gas confined inside the nano channels was maintained around 1 bar. The channel height is maintained at 2nm. The argon atoms interact with each other and with the wall atoms through the Lennard-Jones potential. The wall atoms are modelled using an EAM potential. Further, separate simulations were carried out where a Harmonic potential is used for the atom-atom interaction in the platinum channel. A thermally insulating wall was introduced between the low and high temperature regions and those wall atoms interact with fluid atoms through a repulsive potential. A reduced cut off radius were used to achieve this. Thermal creep is induced by applying a temperature gradient along the channel wall. It was found that flow developed in the direction of the increasing temperature gradient of the wall. An increase in the volumetric flux was observed as the length of the cold and the hot regions of the wall were increased. The effect of temperature gradient and the wall-fluid interaction strength on the flow parameters have been studied to understand the phenomenon better.

    The aim of this study was to describe the variation of soy product intake in 10 European countries by using a standardised reference dietary method. A subsidiary aim was to characterise the pattern of soy consumption among a sub-group of participants with a habitual health-conscious lifestyle (HHL), i.e. non-meat eaters who are fish eaters, vegetarians and vegans. A 24-hour dietary recall interview (24-HDR) was conducted among a sample (5-12%) of all cohorts in the European Prospective Investigation into Cancer and Nutrition (EPIC). Study participants totalled 35 955 after exclusion of subjects younger than 35 or older than 74 years of age. Soy products were subdivided into seven sub-groups by similarity. Distribution of consumption and crude and adjusted means of intake were computed per soy product group across countries. Intake of soy products was also investigated among participants with an HHL. In total, 195 men and 486 women reported consuming soy products in the 24-HDR interview. Although soy product intake was generally low across all countries, the highest intake level was observed in the UK, due to over-sampling of a large number of participants with an HHL. The most frequently consumed soy foods were dairy substitutes in the UK and France and beans and sprouts among mid-European countries. For both genders, the sub-group of soy dairy substitutes was consumed in the highest quantities (1.2 g day-1 for men; 1.9 g day-1 for women). Participants with an HHL differed substantially from others with regard to demographic, anthropometric and nutritional factors. They consumed higher quantities of almost all soy product groups. Consumption of soy products is low in centres in Western Europe. Soy dairy substitutes are most frequently consumed. Participants with an HHL form a distinct sub-group with higher consumptions of fruit, vegetables, legumes, cereals and soy products compared with the other participants.

    We apply a merchant transmission model to the trilateral market coupling (TLC) arrangement among the Netherlands, Belgium and France as an example, and note that it could further be applied to other market splitting or coupling of Europe's different national power markets. In this merchant framework the system operator allocates financial transmission rights (FTRs) to investors in transmission expansion based upon their preferences, and revenue adequacy. The independent system operator (ISO) preserves some proxy FTRs to manage potential negative externalities that may result from expansion projects. This scheme could help European market coupling arrangements attract additional investment. (author)

    Women organize in women’s organizations for various causes across Europe and across the globe today as they have for the past 150 years. The European Women’s Lobby (EWL) is the largest platform for non-governmental women’s organizations in the EU and on their website they state that they have more than 4000 member organizations. It is therefore reasonable to assume that there is a great deal more women’s organizations in the EU, which may not be registered at the EWL, and even more when all t...

    2007-10-01

    To summarize advances in understanding the molecular biology of vestibular schwannomas over the past year. The role of the neurofibromatosis type 2 protein, denoted as merlin or schwannomin, in embryonic development, cellular adherence, and in cell proliferation has become better elucidated in the past year. Likewise, the role of merlin in Schwann cell-axon interaction has been studied. Additionally, two comprehensive analyses of the spectrum of human neurofibromatosis type 2 mutations have been compiled which make up a valuable resource in understanding critical regions of the neurofibromatosis type 2 gene. Neurofibromatosis type 2 screening guidelines for young patients with solitary vestibular schwannomas have been published. The role of electromagnetic radiation via cellular and portable telephones as a predisposing factor to vestibular schwannoma formation has also been the topic of several studies. Based on increased knowledge of the pathways in which merlin functions and the available transgenic and xenograft mouse models, preliminary data regarding directed pharmacotherapy are also summarized. With increased knowledge of the pathologic mechanisms and interacting proteins associated with merlin, the research community is poised to begin trials of targeted interventions in vitro and in the current mouse models.

    Full Text Available Calypogeia azurea, a widespread, subboreal-montane liverwort species, is one of a few representatives of the Calypogeia genus that are characterized by the occurrence of blue oil bodies. The aim of the study was to investigate the genetic variation and population structure of C. azurea originating from different parts of its distribution range (Europe and North America. Plants of C. azurea were compared with C. peruviana, another Calypogeia species with blue oil bodies. In general, 339 gametophytes from 15 populations of C. azurea were examined. Total gene diversity (HT estimated on the basis of nine isozyme loci of C. azurea at the species level was 0.201. The mean Nei’s genetic distance between European populations was equal to 0.083, whereas the mean genetic distance between populations originating from Europe and North America was 0.413. The analysis of molecular variance (AMOVA showed that 69% of C. azurea genetic variation was distributed among regions (Europe and North America, 15% - among populations within regions, and 16% - within populations. Our study revealed that C. azurea showed genetic diversity within its geographic distribution. All examined samples classified as C. azurea differed in respect of isozyme patterns from C. peruviana.

    Atopic dogs with hypersensitivity to Dermatophagoides farinae (Df) have IgE recognizing high molecular weight (MW) allergens more often than the low MW Der f 1 and 2. A new high MW Df allergen, Zen-1, has been identified recently. To determine the IgE reactivity of American and European Df-hypersensitive dogs to Zen-1, Der f 1 and Der f 2. We tested sera from 33 Df-reactive dogs from the USA, 29 from Europe and 15 experimentally sensitized to Df, by ELISA against crude Df, Der f 1, Der f 2 and Zen-1. ELISA inhibition was performed with sera reactive to Zen-1. Intradermal testing (IDT) was also done with the same allergens in 25 other American atopic dogs. Altogether, IgE seropositivity to Zen-1 was more prevalent (86%) than that to Der f 1 (17%) or Der f 2 (19%). The IgE reactivity to Zen-1 was correlated to that against crude Df; this allergen alone inhibited a high percentage (median: 50%; range: 22-84%) of the binding to the crude mite extract. The seropositivity to low MW allergens was highest in experimentally sensitized dogs. Serum IgE recognition of Der f 1 was low in dogs with AD; that to Der f 2 was significantly lower in American dogs (6%) than in European ones (28%). A high prevalence of positive immediate IDT reactions to Zen-1 confirmed the likely relevance of serological results. This study establishes Zen-1 as a major allergen in atopic dogs sensitized to Df. © 2016 ESVD and ACVD.

    Hydration status is linked with health, wellness, and performance. We evaluated hydration status, water intake, and urine output for seven consecutive days in healthy adults. Volunteers living in Spain, Germany, or Greece (n = 573, 39 ± 12 years (51.1% males), 25.0 ± 4.6 kg/m2 BMI) participated in an eight-day study protocol. Total water intake was estimated from seven-day food and drink diaries. Hydration status was measured in urine samples collected over 24 h for seven days and in blood samples collected in fasting state on the mornings of days 1 and 8. Total daily water intake was 2.75 ± 1.01 L, water from beverages 2.10 ± 0.91 L, water from foods 0.66 ± 0.29 L. Urine parameters were: 24 h volume 1.65 ± 0.70 L, 24 h osmolality 631 ± 221 mOsmol/kg Η2Ο, 24 h specific gravity 1.017 ± 0.005, 24 h excretion of sodium 166.9 ± 54.7 mEq, 24 h excretion of potassium 72.4 ± 24.6 mEq, color chart 4.2 ± 1.4. Predictors for urine osmolality were age, country, gender, and BMI. Blood indices were: haemoglobin concentration 14.7 ± 1.7 g/dL, hematocrit 43% ± 4% and serum osmolality 294 ± 9 mOsmol/kg Η2Ο. Daily water intake was higher in summer (2.8 ± 1.02 L) than in winter (2.6 ± 0.98 L) (p = 0.019). Water intake was associated negatively with urine specific gravity, urine color, and urine sodium and potassium concentrations (p hydration level. PMID:27058557

  13. Non-hemagglutinating flaviviruses: molecular mechanisms for the emergence of new strains via adaptation to European ticks.

    Full Text Available Tick-borne encephalitis virus (TBEV causes human epidemics across Eurasia. Clinical manifestations range from inapparent infections and fevers to fatal encephalitis but the factors that determine disease severity are currently undefined. TBEV is characteristically a hemagglutinating (HA virus; the ability to agglutinate erythrocytes tentatively reflects virion receptor/fusion activity. However, for the past few years many atypical HA-deficient strains have been isolated from patients and also from the natural European host tick, Ixodes persulcatus. By analysing the sequences of HA-deficient strains we have identified 3 unique amino acid substitutions (D67G, E122G or D277A in the envelope protein, each of which increases the net charge and hydrophobicity of the virion surface. Therefore, we genetically engineered virus mutants each containing one of these 3 substitutions; they all exhibited HA-deficiency. Unexpectedly, each genetically modified non-HA virus demonstrated increased TBEV reproduction in feeding Ixodes ricinus, not the recognised tick host for these strains. Moreover, virus transmission efficiency between infected and uninfected ticks co-feeding on mice was also intensified by each substitution. Retrospectively, the mutation D67G was identified in viruses isolated from patients with encephalitis. We propose that the emergence of atypical Siberian HA-deficient TBEV strains in Europe is linked to their molecular adaptation to local ticks. This process appears to be driven by the selection of single mutations that change the virion surface thus enhancing receptor/fusion function essential for TBEV entry into the unfamiliar tick species. As the consequence of this adaptive mutagenesis, some of these mutations also appear to enhance the ability of TBEV to cross the human blood-brain barrier, a likely explanation for fatal encephalitis. Future research will reveal if these emerging Siberian TBEV strains continue to disperse westwards

    2016-12-01

    Usher syndrome (USH), the most prevalent cause of hereditary deafness-blindness, is an autosomal recessive and genetically heterogeneous disorder. Three clinical subtypes (USH1-3) are distinguishable based on the severity of the sensorineural hearing impairment, the presence or absence of vestibular dysfunction, and the age of onset of the retinitis pigmentosa. A total of 10 causal genes, 6 for USH1, 3 for USH2, and 1 for USH3, and an USH2 modifier gene, have been identified. A robust molecular diagnosis is required not only to improve genetic counseling, but also to advance gene therapy in USH patients. Here, we present an improved diagnostic strategy that is both cost- and time-effective. It relies on the sequential use of three different techniques to analyze selected genomic regions: targeted exome sequencing, comparative genome hybridization, and quantitative exon amplification. We screened a large cohort of 427 patients (139 USH1, 282 USH2, and six of undefined clinical subtype) from various European medical centers for mutations in all USH genes and the modifier gene. We identified a total of 421 different sequence variants predicted to be pathogenic, about half of which had not been previously reported. Remarkably, we detected large genomic rearrangements, most of which were novel and unique, in 9% of the patients. Thus, our strategy led to the identification of biallelic and monoallelic mutations in 92.7% and 5.8% of the USH patients, respectively. With an overall 98.5% mutation characterization rate, the diagnosis efficiency was substantially improved compared with previously reported methods.

    The major thrust of this research project is to elucidate detailed dynamics of simple elementary reactions that are theoretically important and to unravel the mechanism of complex chemical reactions or photochemical processes that play important roles in many macroscopic processes. Molecular beams of reactants are used to study individual reactive encounters between molecules or to monitor photodissociation events in a collision-free environment. Most of the information is derived from measurement of the product fragment energy, angular, and state distributions. Recent activities are centered on the mechanisms of elementary chemical reactions involving oxygen atoms with unsaturated hydrocarbons, the dynamics of endothermic substitution reactions, the dependence of the chemical reactivity of electronically excited atoms on the alignment of excited orbitals, the primary photochemical processes of polyatomic molecules, intramolecular energy transfer of chemically activated and locally excited molecules, the energetics of free radicals that are important to combustion processes, the infrared-absorption spectra of carbonium ions and hydrated hydronium ions, and bond-selective photodissociation through electric excitation.

  18. Osmosis : a molecular dynamics computer simulation study

    Science.gov (United States)

    Lion, Thomas

    Osmosis is a phenomenon of critical importance in a variety of processes ranging from the transport of ions across cell membranes and the regulation of blood salt levels by the kidneys to the desalination of water and the production of clean energy using potential osmotic power plants. However, despite its importance and over one hundred years of study, there is an ongoing confusion concerning the nature of the microscopic dynamics of the solvent particles in their transfer across the membrane. In this thesis the microscopic dynamical processes underlying osmotic pressure and concentration gradients are investigated using molecular dynamics (MD) simulations. I first present a new derivation for the local pressure that can be used for determining osmotic pressure gradients. Using this result, the steady-state osmotic pressure is studied in a minimal model for an osmotic system and the steady-state density gradients are explained using a simple mechanistic hopping model for the solvent particles. The simulation setup is then modified, allowing us to explore the timescales involved in the relaxation dynamics of the system in the period preceding the steady state. Further consideration is also given to the relative roles of diffusive and non-diffusive solvent transport in this period. Finally, in a novel modification to the classic osmosis experiment, the solute particles are driven out-of-equilibrium by the input of energy. The effect of this modification on the osmotic pressure and the osmotic ow is studied and we find that active solute particles can cause reverse osmosis to occur. The possibility of defining a new "osmotic effective temperature" is also considered and compared to the results of diffusive and kinetic temperatures..

  1. How to communicate safety? Some reflections from European project studies

    2009-12-15

    Attempts to site geological disposal facilities for radioactive waste - and associated public reactions - indicate that communicating safety and demonstrating safety are very different things. The three different approaches to stakeholder engagement undertaken in the context of the PAMINA, ARGONA and CIP projects have provided valuable insights into how risk communication processes and tools can be improved. The approaches used in these projects all involve the participation of interested stakeholders in identifying concerns and issues, which are then examined in a co-operative fashion between stakeholders and developers acting in partnership. Such approaches offer avenues for dialogue and confidence building where such channels were previously not well developed, Full results from the projects will be available in late 2009 for PAMINA and ARGONA and in early 2010 for CIP. The comments and interim insights outlined here will be developed further and incorporated in the overall project outputs, and help inform developing European policy in this area. It is already clear, however, that the approaches used in these projects offer great promise in helping to develop the trust in the institutions and organisations involved that is essential in gaining support and acceptance for the waste management activities now underway across Europe

    Full Text Available The ontology mapping in resilience surveillance on organization level can found utilization in analysis of association between idiosyncrasies and structure adaptability. Starting from the data regarding the economic trends for European Union members from 2014 to 2016 the aim of the research is to analyse the European Union resilience through interpretation of the link between members behaviour and structure convergence. The members positioned in European Union was analysed after organization clusterization of the twenty-eight state members. Two different structures are included into analysis for the studied periods: a structure which incorporates just the state members, and other which also take into account the eurozone blue-chips. In order to analyse the members’ relation in structure a gravity model has been developed, the obtained results for each state members pair are contained in a skew matrix. The values are interpreted through a knowledge-base to highlight the European Union resilience degree.

    The European Society for the Study of Tourette syndrome (ESSTS) was established in Denmark in 2000 by Mary Robertson and Anne Korsgaard. The aims of the organisation are to foster research activity and raise awareness of Tourette syndrome throughout Europe. The organisation went into abeyance in 2002 but was resurrected in 2007 in Bari, Italy. Since that time ESSTS has grown and prospered. We have established elected officers and a constitution. We have successfully applied for three large scale European research grants and have members throughout the European Union. We have held yearly meetings across Europe including two training schools and we have developed successful alliances with patient support groups. ESSTS has developed and published the first European guidelines on assessment, diagnosis and treatment of Tourette syndrome.

    The northern European taxa of genus Melanostoma Schiner, 1860 (Syrphidae, Diptera) are revised. A longstanding question concerning the number of Melanostoma taxa occurring in northern Europe prompted us to contrast and compare their morphological and molecular variability. Particular uncertainty concerned the putative existence of a sibling species of Melanostoma mellinum, and the identity of the taxon Melanostoma dubium in northern Europe due to existence of morphologically similar dark forms of M. mellinum in the northern parts of its distributional range. Partial sequences of two DNA markers, the mitochondrial protein-coding gene cytochrome c oxidase subunit I (COI-3') and the nuclear second internal transcribed spacer (ITS2) were analysed separately under parsimony. The obtained COI-3'gene fragment showed taxon-specific haplotypes and haplotypes that were shared among the taxa. The ITS2 sequences presented genotypes unique to each species, and congruence with our independently established taxonomic entities. Based on congruent signal of the ITS2 sequences and study of morphological characters we establish the presence of four taxa in northern Europe: Melanostoma mellium (= M. dubium nec auctt., syn. n.), M. certum sp. n. (= M. dubium auctt.), M. mellarium stat. n. (= M. mellinum auctt. partim) and M. scalare. Lectotype designations were made for Musca mellina, Syrphus mellarius and Melanostoma mellinum var. melanatus. Melanostoma mellarium = Melanostoma melanatum syn. n.; Melanostoma mellinum = Scaeva dubia syn. n., Melanostoma tschernovi syn. n., and Melanostoma clausseni syn. n. Morphological circumscriptions of the taxa and an identification key are presented.

    External quality assurance (EQA) systems are essential to ensure accurate diagnosis of TB and drug-resistant TB. The implementation of EQA through organising regular EQA rounds and identification of training needs is one of the key activities of the European TB reference laboratory network (ERLTB-Net). The aim of this study was to analyse the results of the EQA rounds in a systematic manner and to identify potential benefits as well as common problems encountered by the participants. The ERLTB-Net developed seven EQA modules to test laboratories' proficiency for TB detection and drug susceptibility testing using both conventional and rapid molecular tools. All National TB Reference laboratories in the European Union and European Economic Area (EU/EEA) Member States were invited to participate in the EQA scheme. A total of 32 National TB Reference laboratories participated in six EQA rounds conducted in 2010-2014. The participation rate ranged from 52.9% - 94.1% over different modules and rounds. Overall, laboratories demonstrated very good proficiency proving their ability to diagnose TB and drug-resistant TB with high accuracy in a timely manner. A small number of laboratories encountered problems with identification of specific Non-tuberculous Mycobacteria (NTMs) (N = 5) and drug susceptibility testing to Pyrazinamide, Amikacin, Capreomycin, and Ethambutol (N = 4). The European TB Reference laboratories showed a steady and high level of performance in the six EQA rounds. A network such as ERLTB-Net can be instrumental in developing and implementing EQA and in establishing collaboration between laboratories to improve the diagnosis of TB in the EU/EEA.

  10. Central European parasitic flatworms of the family Renicolidae Dollfus, 1939 (Trematoda: Plagiorchiida): molecular and comparative morphological analysis rejects the synonymization of Renicola pinguis complex suggested by Odening.

    The Renicolidae are digenean parasites of piscivorous and molluscivorous birds. Although they exhibit few morphological autapomorphies and are highly variable, the numerous suggested re-classifications within the family have never been supported by any molecular analyses. We address the possible synonymization of species within the Renicola pinguis complex suggested previously by Odening. We provide and analyse sequences of two nuclear (ITS2, 28S rDNA) and two mitochondrial (CO1, ND1) DNA loci of central European species of the Renicolidae, namely Renicola lari, Renicola pinguis and Renicola sternae sp. n., and we also provide first sequences of Renicola sloanei. The combined molecular and comparative morphological analysis confirms the previously questioned validity of the three Renicola spp. of highly similar morphology, which display strict niche separation in terms of host specificity and selectivity. We identify two previously unreported clades within the genus Renicola; however, only one of them is supported by the analysis of adult worms. We also provide comparative measurements of the three examined closely related central European renicolids, and describe the newly proposed tern-specialized species Renicola sternae sp. n., which was previously repeatedly misidentified as Renicola paraquinta. Based on the extensive dataset collected in 1962-2015, we update the host spectrum of Renicolidae parasitizing central European birds (Renicola bretensis, R. lari, Renicola mediovitellata, R. pinguis, Renicola secunda and R. sternae sp. n.) and discuss their host-specific prevalence and intensity of infections.

  12. A genome-wide association study identifies five loci influencing facial morphology in Europeans.

    2012-09-01

    Full Text Available Inter-individual variation in facial shape is one of the most noticeable phenotypes in humans, and it is clearly under genetic regulation; however, almost nothing is known about the genetic basis of normal human facial morphology. We therefore conducted a genome-wide association study for facial shape phenotypes in multiple discovery and replication cohorts, considering almost ten thousand individuals of European descent from several countries. Phenotyping of facial shape features was based on landmark data obtained from three-dimensional head magnetic resonance images (MRIs and two-dimensional portrait images. We identified five independent genetic loci associated with different facial phenotypes, suggesting the involvement of five candidate genes--PRDM16, PAX3, TP63, C5orf50, and COL17A1--in the determination of the human face. Three of them have been implicated previously in vertebrate craniofacial development and disease, and the remaining two genes potentially represent novel players in the molecular networks governing facial development. Our finding at PAX3 influencing the position of the nasion replicates a recent GWAS of facial features. In addition to the reported GWA findings, we established links between common DNA variants previously associated with NSCL/P at 2p21, 8q24, 13q31, and 17q22 and normal facial-shape variations based on a candidate gene approach. Overall our study implies that DNA variants in genes essential for craniofacial development contribute with relatively small effect size to the spectrum of normal variation in human facial morphology. This observation has important consequences for future studies aiming to identify more genes involved in the human facial morphology, as well as for potential applications of DNA prediction of facial shape such as in future forensic applications.

    By including immunohistochemical parameters the WHF Task Force for the Definition of Acute and Chronic Myocarditis expanded the light microscopical Dallas criteria of myocarditis. The rapid development of new molecular biological techniques such as polymerase chain reaction (PCR) and in-situ hybridization has improved our understanding of the underlying etiological and pathophysiological mechanisms in inflammatory heart disease. Treatment of dilated cardiomyopathy with inflammation is still controversial, however. The American Myocarditis Treatment Trial could not demonstrate a significant difference in the improvement of ejection fraction between patients with active myocarditis in the cyclosporine/prednisolone treated group when compared to placebo. In the European Study of Epidemiology and Treatment of Inflammatory Heart Disease (ESETCID) patients with acute or chronic myocarditis are treated specifically according to the etiology of the disease. Patients are screened not only for infiltrating cells, but also for the presence of persisting viral genome (enterovirus, cytomegalovirus and adenovirus). By investigating endomyocardial biopsies of 3,055 patients ongoing inflammatory processes in the heart could be found in 17.2%. Only 182 showed a reduced ejection fraction below 45% fulfilling the entrance criteria for the ESETCID trial. These data imply that in symptomatic patients inflammatory heart muscle disease has to be considered regardless of left ventricular function and that endomyocardial biopsy can be an important tool for diagnosis. Virus could be detected in 11.8% (enterovirus 2.2%, cytomegalovirus 5.4%, adenovirus 4.2%). These first epidemiological results of this prospective randomized study demonstrate that viral persistence may contribute to the pathogenesis of inflammatory heart muscle disease, and that in chronic myocarditis viral persistence occurs in a smaller percentage of patients compared to previously published studies which were performed on

    2009-12-01

    Full Text Available Abstract Background Several studies considered the relation between long-term exposure to particulate matter (PM and total mortality, as well as mortality from cardiovascular and respiratory diseases. Our aim was to provide a comprehensive review of European epidemiological studies on the issue. Methods We searched the Medline database for epidemiological studies on air pollution and health outcomes published between January 2002 and December 2007. We also examined the reference lists of individual papers and reviews. Two independent reviewers classified the studies according to type of air pollutant, duration of exposure and health outcome considered. Among European investigations that examined long-term PM exposure we found 4 cohort studies (considering total and cardiopulmonary mortality, 1 case-control study (considering mortality from myocardial infarction, and 4 ecologic studies (2 studies considering total and cardiopulmonary mortality and 2 studies focused on cardiovascular mortality. Results Measurement indicators of PM exposure used in European studies, including PM10, PM2.5, total suspended particulate and black smoke, were heterogeneous. This notwithstanding, in all analytic studies total mortality was directly associated with long-term exposure to PM. The excesses in mortality were mainly due to cardiovascular and respiratory causes. Three out of 4 ecologic studies found significant direct associations between PM indexes and mortality. Conclusion European studies on long-term exposure to PM indicate a direct association with mortality, particularly from cardiovascular and respiratory diseases.

  16. Voluntary agreements, implementation and efficiency. European relevance of case study results. Reflections on transferability to voluntary agreement schemes at the European level

    2000-04-01

    As a policy instrument, voluntary agreements often fascinate policy-makers.This is fuelled by a number of assumed advantages, such as the opportunity for co-operation rather than confrontation, speed and flexibility and the cost-effectiveness. Some advantages might even be accentuated at the European level: Co-operation has added advantage at the European level where the culture of consensus decision is strong. Flexibility is extra attractive for policy makers dealing with an economy less homogeneous than the average national economy. Speed is certainly welcomed by policy-makers otherwise faced with the slow-winding European legislative process. Cost-effectiveness is eagerly sought by European policy makers facing tight administrative budgets and staff limits. This report examines lessons from the VAIE case studies that may be useful to policy makers engaged in the development of voluntary approaches at the European level. These case studies are about voluntary agreement schemes for industrial energy efficiency deployed in Denmark, France, Germany, Netherlands, and Sweden. For a summary of these case studies, please refer to the the VAIE final report. More detailed information is available in the VAIE national reports. It needs to be emphasised that the empirical base is very narrow. The 'lessons' presented can only be hypotheses, based on an inductive leap from a very narrow experience. The reader will need to check these hypotheses against her own broader experience and personal judgement. According to the principle of subsidiarity, voluntary agreements should be implemented at the European level only if that would have significant advantage over national action. Action at the European level, rather than the national level, would have these potential advantages: Being more consistent with the development of the single market; Allowing higher demands on energy efficiency without negative effect on competitiveness and employment; Stimulating company

    2008-10-15

    At the request of Enova (the 'Client'), Garrad Hassan and Partners Limited ('GH') has provided technical advice on capital cost expectations for wind farm developments. In summary, the work provides a survey of the present and future 5-year prognosis for costs and conditions facing developers and suppliers in the European wind power market. The report will be used as a benchmark to support tendering for future Norwegian projects. As such, it will also provide discussion of how project characteristics can influence project cost. Data Used in the Analysis GH has obtained data on the investment costs for 35 projects developed or in development in Europe. The projects represent to the extent possible the characteristics representative of potential Norwegian projects. The data used in this analysis are from actual projects in: France, Germany, Hungary, Ireland, Italy, Northern Ireland, Portugal, Scotland, Spain and Wales. The turbine capacities represented in the data are typically 2 MW or above, except in one case where a mix of turbines sizes was used at the project. GH highlights that because of high demand for turbines, the main manufacturers have recently been offering to meet delivery schedules for new orders from late 2010. For new tenders it is likely that delivery time frames offered will now be for 2011 deliveries. As a result of the current 'Seller's Market', production capacity typically relates directly to the number of turbines sold in the year; therefore for 2007 the annual production capacity was approximately 22 GW. GH is aware that turbine suppliers across the market are working to increase their production capacity in order to ease the pressure on the market, however, there are bottlenecks through the supply chain at the sub component level. As a result, increases in production capacity will likely remain at a relatively steady state in the short term. Energy Assessment The energy assessment of a project is the area

    2003-10-01

    The European Union is developing its noise policy by using a number of expert groups on specific noise issues. One of the most relevant noise problems is railway traffic which is dealt with by Working Group 6 (WG 6). The Commission of the European Union appointed a consortium of six consultants and experts in railway noise to prepare a study on European priorities and strategies for railway noise abatement. The main purpose of this study was to support the work within WG 6 and to create an inventory of measures for future railway noise abatement policy of the European Union. The EURailNoise study was to be completed in autumn 2001. The countries included the European Union member states, together with Norway, and Switzerland, and three prospective members (Hungary, the Czech Republic, and Poland). The EURailNoise study consisted of three main parts. The baseline was a review of current European legislation on railway noise generation as well as noise perception. In parallel a documentation of cases, where technical measures against railway noise had been successfully applied, was prepared using a classification of "good practice", "promising new technology", and "promising research results". The second part covered the potential for further noise reduction demonstrated for High Speed Passenger Traffic, S-Trains, Locomotives, Trams, Freight Traffic, Track Design and finally Wheels and Track Monitoring and Maintenance. Thirdly, a strategy for future activities of the Commission concerning the reduction of rail noise was to be proposed including a proposal for noise emission limits. This paper summarizes the results of the EURailNoise study.

    Ginger is an economically important and valuable plant around the world. Ginger is used as a food, spice, condiment, medicine and ornament. There is available information on biochemical aspects of ginger, but few studies have been reported on its molecular aspects. The main objective of this review is to accumulate the available molecular marker information and its application in diverse ginger studies. This review article was prepared by combing material from published articles and our own research. Molecular markers allow the identification and characterization of plant genotypes through direct access to hereditary material. In crop species, molecular markers are applied in different aspects and are useful in breeding programs. In ginger, molecular markers are commonly used to identify genetic variation and classify the relatedness among varieties, accessions, and species. Consequently, it provides important input in determining resourceful management strategies for ginger improvement programs. Alternatively, a molecular marker could function as a harmonizing tool for documenting species. This review highlights the application of molecular markers (isozyme, RAPD, AFLP, SSR, ISSR and others such as RFLP, SCAR, NBS and SNP) in genetic diversity studies of ginger species. Some insights on the advantages of the markers are discussed. The detection of genetic variation among promising cultivars of ginger has significance for ginger improvement programs. This update of recent literature will help researchers and students select the appropriate molecular markers for ginger-related research.

    2013-01-01

    Extremely fast rotating molecules carrying significantly more energy in their rotation than in any other degree of freedom are known as "super rotors". It has been speculated that super rotors may exhibit a number of unique and intriguing properties. Theoretical studies showed that ultrafast molecular rotation may change the character of molecular scattering from solid surfaces, alter molecular trajectories in external fields, make super rotors surprisingly stable against collisions, and lead to the formation of gas vortices. New ways of molecular cooling and selective chemical bond breaking by ultrafast spinning have been proposed. Owing to the fundamental laws of nature, bringing a large number of molecules to fast, directional and synchronous rotation is rather challenging. As a result, only indirect evidence of super rotors has been reported to date. Here we demonstrate the first controlled creation, direct observation and study of molecular super rotors. Using intense laser pulses tailored to produce an ...

    Background It is largely unknown what medication is used by patients with lower respiratory tract infection (LRTI). Aim To describe the use of self-medication and prescribed medication in adults presenting with LRTI in different European countries, and to relate self-medication to patient characteristics. Design and setting An observational study in 16 primary care networks in 12 European countries. Method A total of 2530 adult patients presenting with LRTI in 12 European countries filled in a diary on any medication used before and after a primary care consultation. Patient characteristics related to self-medication were determined by univariable and multivariable logistic regression analysis. Results The frequency and types of medication used differed greatly between European countries. Overall, 55.4% self-medicated before consultation, and 21.5% after consultation, most frequently with paracetamol, antitussives, and mucolytics. Females, non-smokers, and patients with more severe symptoms used more self-medication. Patients who were not prescribed medication during the consultation self-medicated more often afterwards. Self-medication with antibiotics was relatively rare. Conclusion A considerable amount of medication, often with no proven efficacy, was used by adults presenting with LRTI in primary care. There were large differences between European countries. These findings should help develop patient information resources, international guidelines, and international legislation concerning the availability of over-the-counter medication, and can also support interventions against unwarranted variations in care. In addition, further research on the effects of symptomatic medication is needed. PMID:24567621

    Full Text Available The results of the European elections 2014 in Spain were characterized by the outstanding rise of a new party, Podemos, which obtained five seats in the European Parliament, despite being founded few months before the elections. The present study analyzes both the content and the presence of emotions in Podemos’ discourse on Facebook during the European electoral campaign. In particular, the affective content of both the party’s discourse and the comments of its followers will be analyzed through a pragmatic linguistic approach applied to a corpus of 163 posts and 215 followers’ comments. Results show an insistence on positive emotions in the party’s discourse and a prevalence of negative emotions in the comments of the citizens.

    2003-12-01

    Full Text Available This paper is an attempt to empirically test a theory of access that investigates the logic behind the apparent ad hoc lobbying behavior of business interests in the European Parliament. The theoretical framework tries to explain the degree of access of different organizational forms of business interest representation (companies, associations and consultants to the European Parliament in terms of a theory of the supply and demand of "access goods". The generated hypotheses are analyzed in an empirical study of the EU financial services sector. On the basis of 14 exploratory and 27 semi-structured interviews the hypotheses are checked in the Committee on Economic and Monetary Affairs of the European Parliament.

    Full Text Available With Romania’s integration in the European Union, the media content related to the member states has acquired growing importance. The themes of journalism were enriched with new approaches towards national image in the European context and vice versa. At a first level, the study aims to conduct a quantitative analysis on the news topics broadcasted by Radio Romania Actualitati and Europa FM, for the duration of 32 days. The qualitative component focuses on the topics addressed in radio news in order to see what is the media content which reflects the image of the European Union. The findings show, beyond the numbers, that the editorial policy of the Romanian media is not concerned with the interests of the citizens - from the perspective of common themes - but rather with how can the EU, as a unified body, help member countries solve their problems.

    There are a limited number of papers on the long term effect of air pollution on morbidity and mortality in Europe, particularly with reference to small particles with aerodynamic diameters less than 2.5 microns (PM2.5). Most information comes from US cohort studies, including the American Cancer Society Cancer Prevention Study II, the Harvard Six Cities Study, the Adventists' Health Study of Smog, and the Veterans' Cohort Mortality Study. Ambient levels of several relevant pollutants are more variable within Europe than in the USA, and are in several areas comparably high. Selected European cohort studies, including the Netherlands Cohort Study on Diet and Cancer and the European Prospective Investigation on Cancer and Nutrition study found some association between indicators of air pollution such as PM10 or NO2 and lung cancer risk, but the results were inconsistent and inadequate to address the health effects of exposure to PM2.5. In addition to the effect on mortality, there are open issues on the potential impact of air pollution on childhood asthma, allergy and airway disease. In consideration of the difficulties in estimating the prevalence of the conditions in various populations, these issues require additional focus. In order to provide an indication on possible further analyses of existing European datasets, and on future new studies, a critical review of existing literature (with a focus on European data) was performed. The project resulted in a detailed report (see Appendix 1) and in a paper published in the European Journal of Cancer Prevention.

    2010-01-01

    Sample size calculation is a critical procedure when designing a new biological study. In this chapter, we consider molecular biology studies generating huge dimensional data. Microarray studies are typical examples, so that we state this chapter in terms of gene microarray data, but the discussed methods can be used for design and analysis of any molecular biology studies involving high-dimensional data. In this chapter, we discuss sample size calculation methods for molecular biology studies when the discovery of prognostic molecular markers is performed by accurately controlling false discovery rate (FDR) or family-wise error rate (FWER) in the final data analysis. We limit our discussion to the two-sample case.

    2017-05-01

    The first clinical trial aimed at targeting fundamental processes of aging will soon be launched (TAME: Targeting Aging with Metformin). In its wake is a robust pipeline of therapeutic interventions that have been demonstrated to extend lifespan or healthspan of preclinical models, including rapalogs, antioxidants, anti-inflammatory agents, and senolytics. This ensures that if the TAME trial is successful, numerous additional clinical trials are apt to follow. But a significant impediment to these trials remains the question of what endpoints should be measured? The design of the TAME trial very cleverly skirts around this based on the fact that there are decades of data on metformin in humans, providing unequaled clarity of what endpoints are most likely to yield a positive outcome. But for a new chemical entity, knowing what endpoints to measure remains a formidable challenge. For economy's sake, and to achieve results in a reasonable time frame, surrogate markers of lifespan and healthy aging are desperately needed. This review provides a comprehensive analysis of molecular endpoints that are currently being used as indices of age-related phenomena (e.g., morbidity, frailty, mortality) and proposes an approach for validating and prioritizing these endpoints.

    Models of liquid ethylenediamine (ED) are built using the molecular dynamics approach at temperatures of 293-363 K and a size of 1000 molecules in a basic cell as a cuboid. The structural and dynamic characteristics of liquid ED versus temperature are derived. The gauche conformation of the ED molecule that is characteristic of the gas phase is shown to transition easily into the trans conformation of the molecules in the liquid. NH···N hydrogen bonds are analyzed in liquid ED. The number of H-bonds per ED molecule is found to vary from 5.02 at 293 K to 3.86 at 363 K. The lifetimes in the range of the temperatures and dissociation activation energy for several H-bonds in liquid ED are found to range from 0.574 to 4.524 ps at 293 K; the activation energies are 8.8 kJ/mol for 50% of the H-bonds and 16.3 kJ/mol for 6.25% of them. A weaker and more mobile spatial grid of H-bonds in liquid ED is observed, compared to data calculated earlier for monoethanolamine.

    Full Text Available Lassa virus (LASV is a causative agent of hemorrhagic fever in West Africa. In recent years, it has been imported several times to Europe and North America. The method of choice for early detection of LASV in blood is RT-PCR. Therefore, the European Network for Diagnostics of 'Imported' Viral Diseases (ENIVD performed an external quality assessment (EQA study for molecular detection of LASV. A proficiency panel of 13 samples containing various concentrations of inactivated LASV strains Josiah, Lib-1580/121, CSF, or AV was prepared. Samples containing the LASV-related lymphocytic choriomeningitis virus (LCMV and negative sera were included as specificity controls. Twenty-four laboratories from 17 countries (13 European, one African, one Asian, two American countries participated in the study. Thirteen laboratories (54% reported correct results, 4 (17% laboratories reported 1 to 2 false-negative results, and 7 (29% laboratories reported 3 to 5 false-negative results. This EQA study indicates that most participating laboratories have a good or acceptable performance in molecular detection of LASV. However, several laboratories need to review and improve their diagnostic procedures.

    Systematic sequencing is the method of choice for generating genomic resources for molecular marker development and candidate gene identification in nonmodel species. We generated 47,357 Sanger ESTs and 2.2M Roche-454 reads from five cDNA libraries for European beech (Fagus sylvatica L.). This tree species of high ecological and economic value in Europe is among the most representative trees of deciduous broadleaf forests. The sequences generated were assembled into 21,057 contigs with MIRA software. Functional annotations were obtained for 85% of these contigs, from the proteomes of four plant species, Swissprot accessions and the Gene Ontology database. We were able to identify 28,079 in silico SNPs for future marker development. Moreover, RNAseq and qPCR approaches identified genes and gene networks regulated differentially between two critical phenological stages preceding vegetative bud burst (the quiescent and swelling buds stages). According to climatic model-based projection, some European beech populations may be endangered, particularly at the southern and eastern edges of the European distribution range, which are strongly affected by current climate change. This first genomic resource for the genus Fagus should facilitate the identification of key genes for beech adaptation and management strategies for preserving beech adaptability. © 2015 John Wiley & Sons Ltd.

  6. Does the committee peer review select the best applicants for funding? An investigation of the selection process for two European molecular biology organization programmes.

    Full Text Available Does peer review fulfill its declared objective of identifying the best science and the best scientists? In order to answer this question we analyzed the Long-Term Fellowship and the Young Investigator programmes of the European Molecular Biology Organization. Both programmes aim to identify and support the best post doctoral fellows and young group leaders in the life sciences. We checked the association between the selection decisions and the scientific performance of the applicants. Our study involved publication and citation data for 668 applicants to the Long-Term Fellowship programme from the year 1998 (130 approved, 538 rejected and 297 applicants to the Young Investigator programme (39 approved and 258 rejected applicants from the years 2001 and 2002. If quantity and impact of research publications are used as a criterion for scientific achievement, the results of (zero-truncated negative binomial models show that the peer review process indeed selects scientists who perform on a higher level than the rejected ones subsequent to application. We determined the extent of errors due to over-estimation (type I errors and under-estimation (type 2 errors of future scientific performance. Our statistical analyses point out that between 26% and 48% of the decisions made to award or reject an application show one of both error types. Even though for a part of the applicants, the selection committee did not correctly estimate the applicant's future performance, the results show a statistically significant association between selection decisions and the applicants' scientific achievements, if quantity and impact of research publications are used as a criterion for scientific achievement.

    1996-01-01

    Molecular spectroscopy has achieved rapid and significant progress in recent years, the low temperature techniques in particular having proved very useful for the study of reactive species, phase transitions, molecular clusters and crystals, superconductors and semiconductors, biochemical systems, astrophysical problems, etc. The widening range of applications has been accompanied by significant improvements in experimental methods, and low temperature molecular spectroscopy has been revealed as the best technique, in many cases, to establish the connection between experiment and theoretical calculations. This, in turn, has led to a rapidly increasing ability to predict molecular spectroscopic properties. The combination of an advanced tutorial standpoint with an emphasis on recent advances and new perspectives in both experimental and theoretical molecular spectroscopy contained in this book offers the reader insight into a wide range of techniques, particular emphasis being given to supersonic jet and matri...

    2015-03-11

    We proposed molecular photoionization studies in order to probe correlated events in fundamental scattering phenomena. In particular, we suggested that joint theoretical-experimental studies would provide a window into the microscopic aspects that are of central importance in AMO and chemical physics generally, and would generate useful data for wide array of important DOE topics, such as ultrafast dynamics, high harmonic generation, and probes of nonadiabatic processes. The unifying theme is that correlations between electron scattering dynamics and molecular geometry highlight inherently molecular aspects of the photoelectron behavior.

  9. Study of the seasonal ozone variations at European high latitudes

    The geographic area at high latitudes beyond the polar circle is characterized with long darkness during the winter (polar night) and with a long summertime insolation (polar day). Consequentially, the polar vortex is formed and the surrounding strong polar jet is characterized by a strong potential vorticity gradient representing a horizontal transport barrier. The ozone dynamics of the lower and middle stratosphere is controlled both by chemical destruction processes and transport processes.To study the seasonal ozone variation at high latitudes, ozone vertical distributions are examined, collected from the Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR) (69.3°N, 16.0°E,) station at Andenes and from the stations at Sodankylä (67.4°N, 26.6°E) and at Ny-Ålesund (78.9°N, 11.9°E). The data sets cover the time period from 1994 until 2004. We find a second ozone maximum near 13-15 km, between the tropopause and the absolute ozone maximum near 17-20 km. The maximum is built up by the combination of air mass transport and chemical ozone destruction, mainly caused by the NOx catalytic cycle, which begins after the polar night and intensifies with the increasing day length. Formation of a troposphere inversion layer is observed. The inversion layer is thicker and reaches higher altitudes in winter rather than in summer. However, the temperature inversion during summer is stronger. The formation of an enhanced ozone number density is observed during the spring-summer period. The ozone is accumulated or becomes poor by synoptic weather patterns just above the tropopause from spring to summer. In seasonal average an ozone enhancement above the tropopause is obtained.The stronger temperature inversion during the summer period inhibits the vertical stratosphere-troposphere exchange. The horizontal advection in the upper troposphere and lower stratosphere is enforced during summer. The combination of these mechanisms generates a layer with a very low

  10. Databases for Studies of Infrasound Propagation in the European Arctic

    Gibbons, Steven J.; Ringdal, Frode

    2010-05-01

    Industrial and military sources in northern Fennoscandia and NW Russia generate both seismic and infrasound signals observed at regional distances. Similar seismic signals constrain origin times and explosion yield and, using correlation detectors at the ARCES array, have enabled us to detect and classify hundreds of events from a small number of sites. This has in turn provided superb datasets for infrasound propagation studies. The multi-channel waveform correlation procedure has even had considerable success in detecting closely spaced events when the signals from subsequent events show considerable differences. A post-processing system which examines the alignment of the single-channel cross-correlation traces allows for very low detection thresholds with low false alarm rates. Near-surface explosions at Hukkakero in northern Finland generate infrasound signals on the seismic sensors at ARCES, 175 km to the North, near to the edge of the classical "Zone of Silence". Many tropospheric phase observations can be predicted using ray-tracing given favourable winds at low altitudes. However, the vast majority of the observed infrasound signals - probably refracted from stratospheric heights - are not predicted by ray-tracing, warranting a re-evaluation of propagation models for these distances. In 2008, a mini-array of microbarographs, co-located with ARCES seismometers, also observed later signals probably refracted from thermospheric heights. These signals are more impulsive and of smaller amplitude than the more typically observed signals. A second site near the northern coast of the Kola Peninsula is approximately 250 km from ARCES to the West and Apatity to the South. Despite poor waveform similarity between events, multichannel correlation detectors assign confidently over 350 events over an 8 year period to this site. Infrasound is observed at ARCES for almost all events in the summer and almost no events in the winter, and is observed at Apatity for almost

  17. Student mobility and European identity: Erasmus study as a civic experience?

    Directory of Open Access Journals (Sweden)

    Kristine Mitchell

    2012-12-01

    Full Text Available From its inception, the Erasmus student exchange programme has been promoted by the European Commission as a “civic experience” that instils or enhances a European consciousness among participants. Recent scholarship on European identity has made similar claims about the civic significance of foreign study, yet the empirical basis for these claims remains a subject of debate. This article unpacks the logic of the civic view of Erasmus and submits the individual assumptions to empirical investigation. Based on a survey of more than 2000 respondents from 25 EU countries, this study has the advantage of being both larger and more multinational in composition than the major previous studies. The data largely support the logic of the civic view of Erasmus, demonstrating the intercultural nature of the sojourn abroad, providing compelling evidence that the Erasmus experience contributes to attitudinal changes about Europe among participants, and highlighting significant differences between the Erasmus students and those who do not study abroad when it comes to levels of support for the EU and extent of identifying as European.

    Twenty cases of trisomy 13 were examined with molecular markers to determine the origin of the extra chromosome. Six cases had translocation trisomy: two de novo rob(13q;14q), one paternally derived rob(13q;14q), two de novo t(13q;13q), and one mosaic de novo t(13q;14q), one paternally derived rob(13q;14q), two de novo t(13q;13q), and one mosaic de novo t(13q;13q)r(13). Eighteen of nineteen informative patients were consistant with a maternal origin of the extra chromosome. Lack of a third allele at any locus in any of the three t(13q;13q) cases indicate that all were most likely isochromosomes of post-meiotic origin. In addition, two free trisomy cases were compatible with a somatic origin. Two mosaic free trisomy-13 cases, however, were both consistent with a maternal meiotic origin. The patient with a paternal inheritance of the translocation chromosome was purely coincidental. Since there is not a significantly increased risk for unbalanced offspring of a t(13;14) carrier and most trisomies are maternal in origin, this result should not be surprising; however it illustrates that one cannot infer the origin of translocation trisomy based on parental origin of the translocation. One balanced (non-trisomic) case with a non-mosaic 45,-13,-13,+t(13;13) karyotype was also investigated and was determined to be a somatic Robertsonian translocation between the maternal and paternal homologs, as has been found for all homologous Robertsonian translocations so far investigated. It is therefore also incorrect to assume in de novo translocation cases that the two involved chromosomes are even from the same parent. We cannot therefore infer anything about the origin of the chromosomes 13 and 14 involved in the two cases with de novo t(13q;14q) plus a maternally derived trisomy 13.

    This proposal investigated effects of radiation using a set of archival tissues. Main interests of this proposal were to investigate effects of irradiation alone or in the presence or radioprotectors; to investigate these effects on different tissues; and to use/develop molecular biology techniques that would be suitable for work with archived tissues. This work resulted in several manuscripts published or in preparation. Approach for evaluation of gene copy numbers by quantitative real time PCR has been developed and we are striving to establish methods to utilize Q-RT-PCR data to evaluate genomic instability caused by irradiation(s) and accompanying treatments.

    Background Growth charts based on data collected in different populations and time periods are key tools to assess children’s linear growth. We analyzed the impact of geographic factors and the secular trend on height-for-age charts currently used in European populations, developed up-to-date European growth charts, and studied the effect of using different charts in a sample of growth retarded children. Methods and Findings In an international survey we obtained 18 unique national height-for-age charts from 28 European countries and compared them with charts from the World Health Organization (WHO), Euro-Growth reference, and Centers of Disease Control and Prevention (CDC). As an example, we obtained height data from 3,534 children with end-stage renal disease (ESRD) from 13 countries via the ESPN/ERA-EDTA registry, a patient group generally suffering from growth retardation. National growth charts showed a clear secular trend in height (mean height increased on average 0.6 cm/decade) and a North-South height gradient in Europe. For countries without a recent (>1990) national growth chart novel European growth charts were constructed from Northern and Southern European reference populations, reflecting geographic height differences in mean final height of 3.9 cm in boys and 3.8 cm in girls. Mean height SDS of 2- to 17-year-old ESRD patients calculated from recent national or derived European growth charts (−1.91, 95% CI: −1.97 to −1.85) was significantly lower than when using CDC or WHO growth charts (−1.55, 95% CI: −1.61 to −1.49) (Pmonitoring growth of healthy and diseased European children.

    We investigated whether octogenarian patients with acute myeloid leukemia enrolled onto Cooperative Group clinical trials and treated with intensive induction therapy could be cured, and whether karyotype and selected molecular markers had any prognostic significance in these patients. Among 138 patients with cytogenetic information, normal karyotype was the most common (47.1%) followed by complex karyotype (14.5%) and sole +8 (9.4%). Among these patients, the relapse-free survival rate at 1 year was 37% and 13% at 3 years, and the respective overall survival rates were 24% and 8%. Whereas the 90 patients who survived beyond 30 days had the same relapse-free survival rates, their 1-year and 3-year overall survival rates were 36% and 11%, respectively. Of the 66 patients surviving beyond 30 days who could be classified into European LeukemiaNet genetic groups, those in the intermediate-I group had better overall survival than patients in the adverse group (P=0.01). Among patients with cytogenetically normal acute myeloid leukemia who were tested for the European LeukemiaNet-associated molecular alterations, FLT3-internal tandem duplication and NPM1 mutations, it was found that FLT3-internal tandem duplication (detected in 29% of patients) did not associate with overall survival (P=0.31), whereas NPM1 mutations (30%) were associated with a significantly longer overall survival (P=0.002). We conclude that intensive induction is effective and indicated in selected octogenarians with acute myeloid leukemia, that their overall survival varies among the European LeukemiaNet genetic groups and that NPM1 mutations may be of prognostic significance among octogenarian patients with cytogenetically normal acute myeloid leukemia.

    Full Text Available Bronchiectasis is one of the most neglected diseases in respiratory medicine. There are no approved therapies and few large-scale, representative epidemiological studies. The EMBARC (European Multicentre Bronchiectasis Audit and Research Collaboration registry is a prospective, pan-European observational study of patients with bronchiectasis. The inclusion criterion is a primary clinical diagnosis of bronchiectasis consisting of: 1 a clinical history consistent with bronchiectasis; and 2 computed tomography demonstrating bronchiectasis. Core exclusion criteria are: 1 bronchiectasis due to known cystic fibrosis; 2 age <18 years; and 3 patients who are unable or unwilling to provide informed consent. The study aims to enrol 1000 patients by April 2016 across at least 20 European countries, and 10 000 patients by March 2020. Patients will undergo a comprehensive baseline assessment and will be followed up annually for up to 5 years with the goal of providing high-quality longitudinal data on outcomes, treatment patterns and quality of life. Data from the registry will be available in the form of annual reports. and will be disseminated in conference presentations and peer-reviewed publications. The European Bronchiectasis Registry aims to make a major contribution to understanding the natural history of the disease, as well as guiding evidence-based decision making and facilitating large randomised controlled trials.

    Full Text Available Studies with molecular markers are currently more common for all groups of living organisms. Molecular techniques used in Platyhelminthes parasites of fishes do not merely reveal complex life cycles, but are important for species distinction and the elucidation of the phylogenetic hypothesis. Current research verified which molecular markers were mainly used phylogenetic studies on Platyhelminthes parasites of fish so that subsidies for further phylogenetic studies in Icthyoparasitology could be provided. Data base of CAPES Journals platform was employed for bibliometric analysis comprising the keywords “fish” and “phylogeny” associated with “Cestoda”, “Digenea” or “Monogenea”. Information retrieved was quantified and tabulated. Most studies were on Monogenea (43%, followed by Digenea (37% and Cestoda (18%. Ribosomal molecular markers were the most used in the phylogenetic studies for fish parasites. Due to the advance of molecular biology techniques and of bioinformatics, with more robust phylogenetic analysis, the use of these techniques in other areas such as Ichytioparasitology is on the increase. In fact, molecular phylogenetics and morphological structures analysis have efficiently contributed towards the understanding of phylogenetic relationships among the groups.

    Full Text Available European wine policy is a significant factor influencing winemakers in the European Union. This paper examines perception of this policy by winemakers and other persons working in Czech wine sector on the sample of respondents. Methodological triangulation consisting of non-structured interview and semantic differential was chosen. Field research was carried out, therefore the study uses primary data. Application of the methodology along with the method of evaluation of data creates an original approach which may be applied on several other research questions. General perception of European Wine Policy is complemented with its impact on competitiveness, practical running of vineyards and winery and on future development of winery. Data is statistically evaluated within categories of respondents. Special emphasis is placed on direct payments as a controversial factor of the policy. The policy is perceived as bureaucratic (“all respondents” x = 4.56, and among micro winemakers discriminating (x = 4.5, selfish (x = 4.5 and malfunctioning (x = 3.5. “Professional” winemakers perceive the impact on competitiveness in the Czech market as rather positive (x = 2.67. This study represents pilot research on perception of European Wine Policy by owners of wineries, viticulturists, micro winemakers, a sommelier and a representative of marketing-supporting institution, conducted in the Czech Republic. The author also outlines further direction of research, as the topic is not paid enough scientific attention.

    Full Text Available Abstract Background Reducing harm in drinking environments is a growing priority for European alcohol policy yet few studies have explored nightlife drinking behaviours. This study examines alcohol consumption and blood alcohol concentration (BAC in drinking environments in four European cities. Methods A short questionnaire was implemented among 838 drinkers aged 16-35 in drinking environments in four European cities, in the Netherlands, Slovenia, Spain and the UK. Questions included self-reported alcohol use before interview and expected consumption over the remainder of the night. Breathalyser tests were used to measured breath alcohol concentration (converted to BAC at interview. Results Most participants in the Dutch (56.2%, Spanish (59.6% and British (61.4% samples had preloaded (cf Slovenia 34.8%. In those drinking 5 h. In other nationalities, BAC increases were less pronounced or absent. High BAC (> 0.08% was associated with being male, aged > 19, British and having consumed spirits. In all cities most participants intended to drink enough alcohol to constitute binge drinking. Conclusions Different models of drinking behaviour are seen in different nightlife settings. Here, the UK sample was typified by continued increases in inebriation compared with steady, more moderate intoxication elsewhere. With the former being associated with higher health risks, European alcohol policy must work to deter this form of nightlife.

    The purpose of this study is to investigate the differences in the psychophysical judgment of mobile display color appearances between Europeans and Asians. A total of 50 participants, comprising 20 Europeans (9 French, 6 Swedish, 3 Norwegians, and 2 Germans) and 30 Asians (30 Koreans) participated in this experiment. A total of 18 display stimuli with different correlated color temperatures were presented, varying from 2,470 to 18,330 K. Each stimulus was viewed under 11 illuminants ranging from 2,530 to 19,760 K, while their illuminance was consistent around 500 lux. The subjects were asked to assess the optimal level of the display stimuli under different illuminants. In general, confirming the previous studies on color reproduction, we found a positive correlation in the correlated color temperatures between the illuminants and optimal displays. However, Europeans preferred a lower color temperature compared to Asians along the entire range of the illuminants. Two regression equations were derived to predict the optimal display color temperature (y) under varying illuminants (x) as follows: y = α + β*log(x), where α = -8770.37 and β = 4279.29 for European (R2 = 0.95, p cultural-sensitive approach to enhancing their products' appeal in the global markets.

    2010-11-01

    Genetic diversity and linkage disequilibrium (LD) were investigated in 376 Asian and European accessions of bread wheat (Triticum aestivum L.). After a first and rapid screening about diversity and genetic structure at the whole genome scale using 70 simple sequence repeats (SSRs), we focused on a sequenced contig (ctg954) of 3.1 Mb located on the short arm of chromosome 3B of cv. Chinese Spring, using 32 SSRs and 10 single nucleotide polymorphisms. This contig is part of a multiple fungal resistance region. Mean polymorphism information content value on the 32 SSRs was slightly higher in the Asian genepool (0.396) than that for the European (0.329) pool. Compared with results at the whole genome scale, data from this 3.1-Mb region indicated similar trends in genetic diversity indices between both genepools. Population structure and molecular variance analyses demonstrated significant genetic differentiation and geographical subdivision in both groups of accessions. Concerning LD at the contig level, the European population had a significantly higher mean r(2) value (0.23) than the Asian population (0.18), indicating a stronger LD in the European material. With a mean of 1 marker every 74 kb, the resolution reached here allowed to perform a detailed comparative analysis of the LD and genetic diversity along the complete 3.1-Mb region in both genepools. A sliding-window approach revealed some interesting regions of the contig where LD is increasing when genetic diversity is decreasing. This study provides an in-depth understanding of molecular population genetics in European and Asian wheat gene pools, and prospects for association mapping of important sources of fungal disease resistance.

    2017-11-01

    The present work is a theoretical study of the electronic properties of some molecular structures. The system that takes into account in the study is left lead-donor-molecule-acceptor-right lead. The molecule, such as (phenyl, biphenyl, triphenyl, naphthalene, anthracene, and phenanthrene), is threaded by magnetic flux. This work contains two parts. First is computing density of states of the molecular structures as a closed system by density functional theory (DFT). Second is calculating the transmission probability and electric current of such molecular structures as an open system by steady-state theoretical model. Furthermore, the most important effects, taking into consideration are quantum interference, magnetic flux, and interface structure. Our results show that the connection of the molecule to the two leads, the number of rings, the magnetic flux, and the geometrical structure of the molecule play an important role in determining the energy gap of molecular structures.

    Robinson, Lauren M; Boland, Joseph R; Braverman, John M

    2016-03-01

    A constant rate of molecular evolution among homologous proteins and across lineages is known as the molecular clock. This concept has been useful for estimating divergence times. Here, we revisit a study by Richard Dickerson (J Mol Evol 1:26-45, 1971), wherein he provided striking visual evidence for a constant rate of amino acid changes among various evolutionary branch points. Dickerson's study is commonly cited as support of the molecular clock and a figure from it is often reproduced in textbooks. Since its publication, however, there have been updates made to dates of common ancestors based on the fossil record that should be considered. Additionally, collecting the accession numbers and carefully outlining Dickerson's methods serves as a resource to students of the molecular clock hypothesis.

  2. Molecular Dynamics and Electron Density Studies of Siderophores and Peptides.

    1990-08-01

    The dissertation comprises three separate studies of siderophores and peptides. In the first of these studies the relative potential energies for a series of diastereomers of a siderophore neocoprogen I are evaluated with molecular mechanics force field methods. Charges on the hydroxamate moiety are determined with a synthetic model siderophore compound using valence population refinements, and alternatively, with the theoretical ab initio/ESP calculations. The single diastereomer found in the crystal structure is among four characterized by the low potential energy, while prevalence of Delta vs. Lambda configuration about the iron is found to be a property of the entire series. In the second study the crystal structure of a ferrichrome siderophore ferrirhodin is reported. The crystal structure conformation of the molecular backbone as well as the iron coordination geometry compare well with other ferrichrome structures. The differences between the acyl groups of ferrirubin and ferrirhodin are explored using the methods of molecular mechanics. The third study a 300 ps, 300 K, in vacuo molecular dynamics simulation of didemnin A and B yields distinct molecular conformers, which are different from the one found in the crystal structure or modeled in solution, using the Nuclear Overhauser Effect data. Evaluations of the relative potential energy are performed with short 10 ps simulations in solution. Didemnins are natural depsipeptides isolated from a Caribbean tunicate and characterized by particularly potent antiproliferative and immunomodulatory activity. Conformationally rigid and flexible regions of the molecule are described. A short review of the molecular mechanics methodology is given in the introduction.

    Full Text Available Background: Advances in viral sequence analysis make it possible to track the spread of infectious pathogens, such as HIV, within a population. When used to study HIV, these analyses (i.e., molecular epidemiology potentially allow inference of the identity of individual research subjects. Current privacy standards are likely insufficient for this type of public health research. To address this challenge, it will be important to understand how stakeholders feel about the benefits and risks of such research. Design and Methods: To better understand perceived benefits and risks of these research methods, in-depth qualitative interviews were conducted with HIV-infected individuals, individuals at high-risk for contracting HIV, and professionals in HIV care and prevention. To gather additional perspectives, attendees to a public lecture on molecular epidemiology were asked to complete an informal questionnaire. Results: Among those interviewed and polled, there was near unanimous support for using molecular epidemiology to study HIV. Questionnaires showed strong agreement about benefits of molecular epidemiology, but diverse attitudes regarding risks. Interviewees acknowledged several risks, including privacy breaches and provocation of anti-gay sentiment. The interviews also demonstrated a possibility that misunderstandings about molecular epidemiology may affect how risks and benefits are evaluated. Conclusions: While nearly all study participants agree that the benefits of HIV molecular epidemiology outweigh the risks, concerns about privacy must be addressed to ensure continued trust in research institutions and willingness to participate in research.

    We report on temperature dependent magnetic susceptibility and Moessbauer effect studies of the influence of hydrostatic pressure (up to 1.2 GPa) on dynamic electronic structure phenomena in 3d transition metal coordination compounds. The systems under investigation are mononuclear spin crossover compounds of iron (II) and chromium (II), dinuclear complexes of iron (II) exhibiting coexistence of intramolecular antiferromagnetic coupling and thermal spin crossover, 1D, 2D and 3D polynuclear spin crossover complexes of iron (II), a valence tautomeric system of cobalt (II) showing a thermal transition from a high spin [Co{sup II} (semiquinone)] to a low spin [Co{sup II} (catecholate)] species on lowering the temperature and a photomagnetically active Prussian blue type system with temperature- and pressure induced electron transfer. It is demonstrated that pressure effect studies can be very helpful in elucidating the mechanisms and cooperative interactions of solid state compounds with electronic bistability.

    Differences in the genetic architecture of inflammatory bowel disease between different European countries and ethnicities have previously been reported. In the present study, we wanted to assess the role of 11 newly identified UC risk variants, derived from a recent European UC genome wide association study (GWAS) (Franke et al., 2010), for 1) association with UC in the Nordic countries, 2) for population heterogeneity between the Nordic countries and the rest of Europe, and, 3) eventually, to drive some of the previous findings towards overall genome-wide significance. Eleven SNPs were replicated in a Danish sample consisting of 560 UC patients and 796 controls and nine missing SNPs of the German GWAS study were successfully genotyped in the Baltic sample comprising 441 UC cases and 1156 controls. The independent replication data was then jointly analysed with the original data and systematic comparisons of the findings between ethnicities were made. Pearson's χ2, Breslow-Day (BD) and Cochran-Mantel-Haenszel (CMH) tests were used for association analyses and heterogeneity testing. The rs5771069 (IL17REL) SNP was not associated with UC in the Danish panel. The rs5771069 (IL17REL) SNP was significantly associated with UC in the combined Baltic, Danish and Norwegian UC study sample driven by the Norwegian panel (OR = 0.89, 95% CI: 0.79-0.98, P = 0.02). No association was found between rs7809799 (SMURF1/KPNA7) and UC (OR = 1.20, 95% CI: 0.95-1.52, P = 0.10) or between UC and all other remaining SNPs. We had 94% chance of detecting an association for rs7809799 (SMURF1/KPNA7) in the combined replication sample, whereas the power were 55% or lower for the remaining SNPs.Statistically significant PBD was found for OR heterogeneity between the combined Baltic, Danish, and Norwegian panel versus the combined German, British, Belgian, and Greek panel (rs7520292 (P = 0.001), rs12518307 (P = 0.007), and rs2395609 (TCP11) (P = 0.01), respectively).No SNP reached genome

    An optical study of N-(p-n-alkyloxybenzylidene)-p-n-butyloxyanilines, nO.O4 compounds with the alkoxy chain number n = 1, 3, 6, 7, and 10 has been carried out by measuring the refractive indices using modified spectrometer and direct measurement of birefringence employing the Newton's rings method. Further, the molecular polarizability anisotropies are evaluated using Lippincott δ-function model, the molecular vibration method, Haller's extrapolation method, and scaling factor method. The molecular polarizabilities α e and α 0 are calculated using Vuk's isotropic and Neugebauer anisotropic local field models. The order parameter S is estimated by employing the molecular polarizability values determined from experimental refractive indices and density data and the polarizability anisotropy values. Further, the order parameter S is also obtained directly from the birefringence data. A comparison has been carried out among the order parameter obtained from different ways and the results are compared with the body of the data available in the literature.

    As the European population ages, the demand for nursing care increases. Yet, a shortage of nurses at the labour market exists or is predicted for most European countries. There are no adequate solutions for this shortage yet, and recruitment of future nurses is difficult. Therefore, retaining nurses for the profession is urgent. To determine factors associated with nurses' intention to leave the profession across European countries. A multi-country, multi-centre, cross-sectional analysis of survey data. 2025 surgical and medical units from 385 hospitals in ten European countries that participated in the RN4Cast study. Hospital selection was based on a stratified randomised selection procedure. All nurses from the participating medical and surgical hospital wards received a survey. 23,159 nurses (64%) returned the survey. The nurse survey included questions about intention to leave the profession, nurse characteristics, factors related to work environment, patient-to-nurse staffing ratio, burnout and perceived quality and safety of care. Multilevel regression analyses with 'intention to leave the profession' as dependent variable were conducted for all 10 countries combined as well as per country. Overall, 9% of the nurses intended to leave their profession. This varied from 5 to 17% between countries. Seven factors were associated with intention to leave the profession at European level: nurse-physician relationship (OR 0.86; 95%CI 0.79-0.93), leadership (OR 0.78; 95% CI 0.70-0.86), participation in hospital affairs (0.68; 95%CI 0.61-0.76), older age (OR 1.13; 95%CI 1.07-1.20), female gender (OR 0.67; 95%CI 0.55-0.80), working fulltime (OR 0.76; 95%CI 0.66-0.86) and burnout (OR 2.02; 95%CI 1.91-2.14). The relevance of these factors differed for the individual countries. Nurse perceived staffing adequacy, patient-to-nurse staffing ratio, perceived quality and safety of care and hospital size were not associated with intention to leave at a European level. Burnout is

    Marjolein Bonthuis

    Full Text Available BACKGROUND: Growth charts based on data collected in different populations and time periods are key tools to assess children's linear growth. We analyzed the impact of geographic factors and the secular trend on height-for-age charts currently used in European populations, developed up-to-date European growth charts, and studied the effect of using different charts in a sample of growth retarded children. METHODS AND FINDINGS: In an international survey we obtained 18 unique national height-for-age charts from 28 European countries and compared them with charts from the World Health Organization (WHO, Euro-Growth reference, and Centers of Disease Control and Prevention (CDC. As an example, we obtained height data from 3,534 children with end-stage renal disease (ESRD from 13 countries via the ESPN/ERA-EDTA registry, a patient group generally suffering from growth retardation. National growth charts showed a clear secular trend in height (mean height increased on average 0.6 cm/decade and a North-South height gradient in Europe. For countries without a recent (>1990 national growth chart novel European growth charts were constructed from Northern and Southern European reference populations, reflecting geographic height differences in mean final height of 3.9 cm in boys and 3.8 cm in girls. Mean height SDS of 2- to 17-year-old ESRD patients calculated from recent national or derived European growth charts (-1.91, 95% CI: -1.97 to -1.85 was significantly lower than when using CDC or WHO growth charts (-1.55, 95% CI: -1.61 to -1.49 (P<0.0001. CONCLUSION: Differences between height-for-age charts may reflect true population differences, but are also strongly affected by the secular trend in height. The choice of reference charts substantially affects the clinical decision whether a child is considered short-for-age. Therefore, we advocate using recent national or European height-for-age charts derived from recent national data when monitoring growth

    The Brachylaimoidea are digenean parasites of vertebrates, including humans, domestic animals, poultry and wild game. Numerous Brachylaimoidea, particularly adults of Brachylaima and Leucochloridium, are difficult to identify to species. We provide and analyse sequences of two nuclear (18S rDNA, ITS2) and two mitochondrial (CO1, ND1) DNA loci of central European species of the Brachylaimoidea, namely Leucochloridium holostomum, Leucochloridium paradoxum, Leucochloridium perturbatum, Leucochloridium subtilis, Leucochloridium vogtianum, Urotocus rossitensis, Urogonimus macrostomus, Michajlovia migrata, Leucochloridiomorpha lutea, Brachylaima arcuatus, Brachylaima fuscata and Brachylaima mesostoma. We identified three clades in the genus Leucochloridium, which do not correspond to the previously suggested subgenera Neoleucochloridium, Papilloleucochloridium and Leucochloridium. We reject classification of Urotocus and Urogonimus in Leucochloridiinae, and, instead, re-establish the subfamilies Urotocinae and Urogoniminae. We synonymize the genus Renylaima with the genus Brachylaima. We reject M. migrata as a member of Leucochloridiinae sensu stricto or Brachylaimidae suggested by some previous authors. We found that the previously sequenced Glaphyrostomum sp. does not cluster with any hitherto sequenced Brachylaimidae. We also provide comparative measurements of the examined central European Brachylaimoidea, address the the specificity of their localization in the host and discuss their host-specific prevalence and intensity of infections based on the extensive dataset of birds examined in 1962-2015.

    Highlights: ► We identify the binding mode of PCB153 to human serum albumin (HSA). ► Spectroscopic and molecular modeling results reveal that PCB153 binds at the site II. ► The interaction is mainly governed by hydrophobic and hydrogen bond forces. ► The work helps to probe transporting, distribution and toxicity effect of PCBs. -- Abstract: Polychlorinated biphenyls (PCBs) possessed much potential hazard to environment because of its chemical stability and biological toxicity. Here, we identified the binding mode of a representative compound, PCB153, to human serum albumin (HSA) using fluorescence and molecular dynamics simulation methods. The fluorescence study showed that the intrinsic fluorescence of HSA was quenched by addition of PCB153 through a static quenching mechanism. The thermodynamic analysis proved the binding behavior was mainly governed by hydrophobic force. Furthermore, as evidenced by site marker displacement experiments using two probe compounds, it revealed that PCB153 acted exactly on subdomain IIIA (site II) of HSA. On the other hand, the molecular dynamics studies as well as free energy calculations made another important contribution to understand the conformational changes of HSA and the stability of HSA-PCB153 system. Molecular docking revealed PCB153 can bind in a large hydrophobic activity of subdomain IIIA by the hydrophobic interaction and hydrogen bond interactions between chlorine atoms and residue ASN391. The present work provided reasonable models helping us further understand the transporting, distribution and toxicity effect of PCBs when it spread into human blood serum.

  3. A phenological study on European larch (Larix decidua Mill. in the Drahanská vrchovina highlands

    Emilie Bednářová

    2008-01-01

    Full Text Available The phenological study on the onset and duration of individual phenological phases of European larch (Larix decidua Mill. has been performed using sample trees growing in the research station of the Faculty of Forestry and Wood Technology, MUAF Brno for altogether 15 years. This study involves also recording of meteorological data. In this region, the European larch is an introduced woody species and its share in the stand composition is approximately 8%. In European larch, the phenological stages have a markedly periodic character but they are also largely dependent on a complex of exogenous conditions, especially of climatic effects; this was corroborated also in studies on the phenology of other forest tree species growing in this region. Results of this phenological study demonstrated that the spring phenophases were influenced above all by air temperatures while the autumn ones were dependent, besides temperatures and precipitation, also on the duration of assimilation apparatus activities. The onset of breaking of needles occurred between Days 89 and the 110 of the calendar year. A full development of the assimilation area was reached between Days 125 and 150. The onset of individual phenophases was determined by threshold air temperatures, which were markedly different in individual forest trees. This requirement could be expressed at best by the sum of effective temperatures (i.e. air temperatures above 5 °C. In the analysed fifteen-year study period, the sum of effective temperatures for European larch ranged from 1 301.0 to 2 337.0 °C within the period delimited by dates of the flushing and 100-percent fall (abscission of needles.Results of a long-term phenologic monitoring of forest woody species may be used when evaluating the condition of forest stands from the viewpoint of expected global climatic changes.

    of Capability-Expectations Gap in the study of European foreign policy. Through examples from the literature, it is shown that the concept sets up standards for the EU as a foreign policy actor that are not met by most other international actors and that this curtails analysis of EU foreign policy......This book argues that theories of European foreign policy are performative: they create the objects they analyse.The book first outlines the performativity approach to the role of theories based on the work of Derrida. It then examines the performative role of Christopher Hill's concept....... It then demonstrates that the widespread use of the concept of ‘gap’ in different forms affects the way in which EU foreign policy has been studied and that it always produces the same result: the EU is an unfulfilled actor outside the realm of “normal” actors in IR....

    Full Text Available This research is devoted to the study of vertical movements of the European crust on the basis of two independent methods, namely tide gauge and GNSS observations results. The description and classification of factors affecting sea level change has been made. The precision with which the movement of the earth's crust according to the results of tide gauge observations can be explored has been calculated . A methodology to identify the duration of tide gauge observations required for studies of vertical movements of the earth 's crust has been presented. Approximation of tide gauge time series with the help of Fourier series has been implemented, the need for long-term observations in certain areas has been explained. The diagram of the velocities of the vertical movements of the European crust on the basis of the tide gauge data and GNSS observations has been built and the anomalous areas where the observations do not coincide have been identified.

    The integration of European energy markets is a key goal of EU energy policy, and has also been the focal point of many scientific studies in recent years. International markets for coal, oil, natural gas and electricity have previously been investigated in order to determine the extent of the respective markets. This study enhances this field of research to bioenergy markets. Price series data and time series econometrics are used to determine whether residential sector wood pellet markets of Austria, Germany and Sweden are integrated. The results of the econometric tests show that the German and Austrian markets can be considered to be integrated, whereas the Swedish market is separate from the other two countries. Although increased internationalization of wood pellet markets is likely to contribute to European price convergence and market integration, this process is far from completed. (author)

The main objective was to sustain environmental health policy by building a coherent and sustainable framework and by increasing the comparability...... of data across countries. A pilot study to test common guidelines for setting up surveys was considered a key step in this process. Through a bottom-up approach that included all stakeholders, a joint study protocol was elaborated. From September 2011 till February 2012, 17 European countries collected...... metabolites and Bisphenol A in urine were added to take into account increasing public and political awareness for emerging types of contaminants and to test less advanced markers/markers covered by less analytical experience. Extensive efforts towards chemo-analytical comparability were included. The pilot...

  10. A regime - switching approach to studying speculative attacks : focus on European Monetary System crises

    OpenAIRE

    Peria, Maria Soledad Martinez

    1999-01-01

    The author uses a regime switching framework to study speculative attacks against European Monetary System (EMS) currencies during 1979-93. She identifies speculative attacks by modeling exchange rates, reserves, and interest rates as time series subject to discrete regime shifts. She assumes two states:"tranquil"and"speculative."She models the probabilities of switching between states as a function of fundamentals and expectations. She concludes that: A) The switching models with time -varyi...

    2011-12-01

    Full Text Available This paper presents a literature review concerning the importance of molecular approaches in bivalve’s population study. The class Bivalvia counts more than 20,000 species with a wide distribution both in freshwater and marine environment. Given their importance especially in aquaculture as a source of food, they have also a strong economic impact upon human society. This review encompasses best practices in bivalve studies from field sampling to laboratory analyses, addressing questions about molecular methods and tools commonly used by specialized researchers. Molecular tools specifically deals with phylogeography, population genetics, biology, ecology and taxonomy. In all these fields, molecular markers play an important role by completing some unanswered questions such as the role of the bivalves in the ecosystems in relation to anthropogenic and global change issues. Numerous genetic markers were developed for specific problems, thereferore we identify as a major issue the absence of uniform and universally recognized methods. The various sections of the paper emphasize from peer reviewed literature literature which are considered the most useful markers, costs and benefits of different methodology, major gaps of knowledge.in bivalve population studies. By reviewing virtually all genetic markers employed during nearly half a century of bivalve molecular research, in our opinion two are the best option “tools: the mitochondrial COI (cytochrome oxidase subunit I and nuclear ITS2 (internal transcribed spacer 2.

    The mesoporous zeolite is a novel porous material possessing mesopores as well as the inherent micropores of zeolites. This material can exhibit the dual merits of two different pore structures and enable zeolites to have maximum structural functions. During the past few decades, various synthetic strategies have been well developed. However, up to now, there has only been a few attempts to model mesoporous zeolites. In this paper, the structural properties of a mesoporous ZSM-5 type molecular sieve, which has mesopore walls that are made up of ZSM-5 zeolite-like frameworks, were studied using an atomistic model. The full-atom model of the mesoporous ZSM-5 type molecular sieve was constructed using a molecular modeling technique. The structure model was characterized by estimating the nitrogen accessible solvent surface area, small-angle and wide-angle X-ray diffraction patterns, toluene and benzene adsorption. It was found that these simulated results match well with the experimental data. Furthermore, the present approach can be extended to construct other micro-mesoporous molecular sieve structure models in the future.

    In Europe, volunteers have an important role in the delivery of palliative care. As part of the EU co-funded Europall project, 4 aspects of volunteering in palliative care were studied for 7 European countries (Belgium, England, France, Germany, the Netherlands, Poland, and Spain). These included (1) involvement of volunteers in palliative care, (2) organization of palliative care volunteering, (3) legal regulations concerning volunteering, and (4) education and training of palliative care volunteering. A literature search combined with an interview study. Information from the scientific literature, and country-specific policy documents were obtained and completed, along with data of consecutive semi-structured interviews with experts in the field of palliative care in the participating countries. In all countries, volunteers appeared to be involved in palliative care, yet their involvement across health care settings differed per country. England, for example, has the highest number of volunteers whereas Spain has the lowest number. Volunteering is embedded in law and regulations in all participating countries except for England and the Netherlands. In all participating countries, training programs are available and volunteers are organized, both on a national and a regional level. This study provides a descriptive overview of volunteer work in palliative care in 7 European countries, with a focus on the organizational aspects. Further research should concentrate on the roles and responsibilities of volunteers in the care for the terminally ill in different European health systems. © 2014 World Institute of Pain.

    Pheochromocytoma (pheo) is the second component of the multiple endocrine neoplasia type 2 (MEN 2) syndrome. Clinical expression is sometimes poor, and chronology between medullary thyroid carcinoma (MTC) and pheo is not well evaluated. Therefore, a retrospective study was done in eight European countries in order to precise the main characteristics of pheo in MEN 2. Data from 300 MEN 2 patients with pheo (274 MEN 2 A and 26 MEN 2 B) were obtained from cases registered by the EuroMen study group, and collected by a medical standardized questionnaire. These cases occurred between 1969 and 1992. Mean age at diagnosis of pheo was 39.5 years (range 14-68 years) in MEN 2A and 32.4 years (range 15-41 years) in MEN 2B patients. Pheo occurred first in 25.1% of the cases (2-15 years before diagnosis of MTC) and after MTC in 40.2% (2-11 years). In other cases (34.7%), MTC and pheo were diagnosed at the same time. Involvement was bilateral in 67.8% of cases. Malignancy was only 4%. Thirty-nine deaths occurred in these 300 patients, 64.1% were linked in pheo, 23.1% to MTC and 12.8% to other causes. Surgery was unilateral in 39.7% of the cases and bilateral adrenalectomy was the first procedure in 48.4%. A bilateral adrenalectomy in two steps had to be done in 11.9% of cases. In conclusion, these results justify systematic and prolonged biochemical screening of pheo during follow-up of MTC and address some questions about the best mode of surgery.

    Full Text Available Abstract Background The challenges posed by the rapidly ageing population, and the increased preponderance of disabled people in this group, coupled with the rising level of public expenditure required to service the complex organization of long term care (LTC delivery are causing increased pressure on LTC systems in Europe. A pan-European survey was carried out to evaluate whether patterns of LTC can be identified across Europe and what are the trends of the countries along them. Methods An ecological study was conducted on the 27 EU Member States plus Norway and Iceland, referring to the period 2003-2007. Several variables related to organizational features, elderly needs and expenditure were drawn from OECD Health Data and the Eurostat Statistics database and combined using Multiple Factor Analysis (MFA. Results Two global Principal Components were taken into consideration given that their expressed total variance was greater than 60%. They were interpreted according to the higher (more than 0.5 positive or negative correlation coefficients between them and the original variables; thus patterns of LTC were identified. High alignment between old age related expenditure and elderly needs characterizes Nordic and Western European countries, the former also having a higher level of formal care than the latter. Mediterranean as well as Central and South Eastern European countries show lower alignment between old age related expenditure and elderly needs, coupled with a level of provision of formal care that is around or slightly above the average European level. In the dynamic comparison, linear, stable or unclear trends were shown for the studied countries. Conclusions The analysis carried out is an explorative and descriptive study, which is an attempt to reveal patterns and trends of LTC in Europe, allowing comparisons between countries. It also stimulates further researches with lower aggregated data useful to gain meaningful policy

    Full Text Available Idiopathic pulmonary fibrosis (IPF affects lung parenchyma with progressing fibrosis. In this study, we aimed to replicate MUC5B rs35705950 variants and determine new plausible candidate variants for IPF among four different European populations. We genotyped 26 IPF candidate loci in 165 IPF patients from four European countries: Czech Republic (n = 41, Germany (n = 33, Greece (n = 40, France (n = 51 and performed association study comparing observed variant distribution with this obtained in a genetically similar Czech healthy control population (n = 96 described in our earlier data report. A highly significant association for a promoter variant (rs35705950 of mucin encoding MUC5B gene was observed in all IPF populations, individually and combined [OR (95% CI; p-value as 5.23 (8.94-3.06; 1.80x10-11. Another non-coding variant, rs7934606 in MUC2 was significant among German patients [2.85 (5.05-1.60; 4.03x10-4] and combined European IPF cases [2.18 (3.16-1.50; 3.73x10-5]. The network analysis for these variants indicated gene-gene and gene-phenotype interactions in IPF and lung biology. With replication of MUC5B rs35705950 previously reported in U.S. populations of European descent and indicating other plausible polymorphic variants relevant for IPF, we provide additional reference information for future extended functional and population studies aimed, ideally with inclusion of clinical parameters, at identification of IPF genetic markers.

    2002-10-01

    The study of the molecular biology of Coccidioides sp. is only just beginning. As the importance of coccidioidomycosis grows as a public health problem, our need for understanding of pathogenesis, immune responses, and improved antifungal therapy also increases in proportion. Tools have now become available to study gene manipulation in this pathogen and this will allow molecular approaches to be used. Genetic experiments will also be accelerated by the availability of the whole coccidioidal genome, expected to be made public in the spring of 2003 (see http://www.tigr.org/tdb/tgi/cigi/GenInfo.html). Thus, there seems to be several reasons to expect considerable progress in the coming years.

    2011-01-01

    Full Text Available The objective of this article is to compare the self-regulatory systems of the journalistic profession in Austria, Germany, Denmark, Estonia, Spain, France and Poland. Based on the analysis of the different cases and situations in these seven countries, we offer a comparative analysis of the existence of: ethical codes, pro-consumers associations, print and audiovisual press councils, level of organization and unionism among journalists. The results reveal deficiencies in the European systems as well as progressions in the implementation of self-regulation tools in the journalistic profession, mainly in the field of print and audiovisual media. In most European countries under study, online newspapers lack self-regulatory tools, except for the regulation coming from their parent print or broadcast media companies.

    with the other cities tested. An enrichment of MDMA with the R-(−)-enantiomer was observed in European wastewaters indicating MDMA consumption rather than disposal of unused drug. MDA's chiral signature indicated its enrichment with the S-(+)-enantiomer, which confirms its origin from MDMA metabolism in humans......The aim of this paper is to present the first study on spatial and temporal variation in the enantiomeric profile of chiral drugs in eight European cities. Wastewater-based epidemiology (WBE) and enantioselective analysis were combined to evaluate trends in illicit drug use in the context......-(+)-enantiomer in wastewater suggests stereoselective metabolism in humans, hence consumption, rather than direct disposal of the drug. The investigation of drug precursors, such as ephedrine, showed that their presence was reasonably ascribed to their medical use....

    Ezequiel Perez-Inestrosa

    2011-09-01

    Full Text Available A series of synthetic benzylpenicillinoylated dendrimers has been prepared using up to 4th generation PAMAM dendrimers. These nanoconjugates, as nanosized Dendritic Antigens, are useful in the diagnostic evaluation of drug allergy due to specific molecular recognition with the Human Immunological System (IgE. The morphology and dimensions of the conjugates coupled to the orientation of the peripheral benzylpenicillin residues in the dendrimers may play key roles in such molecular recognition processes. Herein, the characterization and conformation of these structures are studied by a detailed analysis of 1D (1H and 13C NMR and 2D NMR (1H,1H-NOESY spectra. These dendrimers in explicit solvent were studied by the atomistic forcefield-based molecular dynamics. Structural properties such as shape, radius-of-gyration and distribution of the monomers will be discussed in relation to the experimental observations.

    Stress is hypothesized to facilitate the development of obesity, whose the foundations are already set during childhood and adolescence. We investigated the relationship between the stress-system, selected mechanisms of energy homeostasis and insulin resistance (IR) in a sample of European adolescents. Within HELENA-CSS, 723 adolescents (12.5-17.5 years) from 10 European cities provided all the necessary data for this study. Fasting blood samples were collected for cortisol, leptin, insulin and glucose analysis. HOMA-IR was calculated from insulin and glucose concentrations. Adolescents' body fat (BF) %, age and duration of exclusive breastfeeding were assessed. For boys and girls separately, the relationship of cortisol with leptin, insulin, glucose and HOMA-IR was examined by computing Pearson correlation coefficients and Hierarchical Linear Models (HLMs), with 'city' as cluster unit, adjusting for age, BF% and duration of exclusive breastfeeding. In boys, Pearson correlation coefficients illustrated positive correlations of cortisol with insulin (r = 0.144; p = 0.013), glucose (r = 0.315; p adolescents' age, BF% and duration of exclusive breastfeeding after computing HLMs. This study suggests that the stress-system is positively related to mechanisms of energy homeostasis and IR in European adolescents, and reveals a potential small gender difference in this relationship. The hypothesis that stress might facilitate the development of obesity during adolescence is supported. Copyright © 2014 Elsevier B.V. All rights reserved.

    While there has been systematic research on the experiences of immigrant patients in mental health services within certain European countries, little research has explored the experiences of mental health professionals in the delivery of services to immigrants across Europe. This study sought to explore professionals' experiences of delivering care to immigrants in districts densely populated with immigrants across Europe. Forty-eight semi-structured interviews were conducted with mental health care professionals working in 16 European countries. Professionals in each country were recruited from three areas with the highest proportion of immigrants. For the purpose of this study, immigrants were defined as first-generation immigrants born outside the country of current residence, including regular immigrants, irregular immigrants, asylum seekers, refugees and victims of human trafficking. Interviews were transcribed and analysed using thematic analysis. The interviews highlighted specific challenges to treating immigrants in mental health services across all 16 countries including complications with diagnosis, difficulty in developing trust and increased risk of marginalisation. Although mental health service delivery varies between and within European countries, consistent challenges exist in the experiences of mental health professionals delivering services in communities with high proportions of immigrants. Improvements to practice should include training in reaching appropriate diagnoses, a focus on building trusting relationships and measures to counter marginalisation.

    In the present study, molecular imprinting was used to develop a method based on noncovalent interaction for the synthesis of a monocrotophos-specific polymer. The selective binding characteristics of the template polymer were evaluated by 1H NMR and ultraviolet spectrometry. The polymer obtained was found to interact specifically with monocrotophos by cooperative hydrogen bonding. The infrared spectrometry of the polymer further indicated that there were some functional groups in the moleculary imprinted polymer which could interact on the template.

    Full Text Available Abstract Background The post marketing safety surveillance program for a drug containing a new chemical entity should assess both, the safety outcomes that relate specifically to the targeted population, as well as those that could potentially be related to special pharmacological characteristics of the drug. Active safety surveillance using valid epidemiological study designs has been proven to be a pertinent and reliable method to approach this endeavor. Methods/design The primary objective of the study is to compare incidence rates of serious adverse events in users of all types of newly prescribed oral HRT products. This active surveillance study will assess pertinent cardiovascular outcomes - in particular venous and arterial thromboembolism - and other serious adverse events (SAEs in new HRT users over a period of several years. One product under surveillance is Angeliq®, which contains the novel progestagen drospirenone (DRSP combined with estradiol. In addition, all other oral combined HRT products with a novel progestagen or estrogen that will be newly marketed during the study period will be studied. These new HRT products will be compared with established HRT products. The combined cohort will include at least 30,000 women recruited in several European countries. At least 90,000 years of observation are expected from the field work which started in early 2002 and will end around 2008. The participating women will complete a baseline survey using a self-administered questionnaire to describe the baseline risk. After 6 months, 12 months, and then on an annual basis, they will fill out a questionnaire in which they record complaints and events during the use of the prescribed HRTs. All adverse outcomes occurring during the observational period will be evaluated. Discussion A complete lifetime medical history, individually validated SAEs over time, and a low loss to follow-up rate are essential for a robust safety assessment. Therefore

    We report short and efficient scalable syntheses of enantiomerically pure (3R,4S)-3-(hydroxymethyl4-(hydroxyethyl))-piperidine and 1-hydroxymethyl-octahydro-1H-pyrano[3,4-c]pyridine scaffolds. The alkaloid core was readily synthesized from naturally occurring quinine and can serve as a valued starting point for drug-discovery. Cleavage of a terminal 1,2-diol and acid catalysed epoxide opening cyclization are the key steps involved. A number of members of a projected small-molecular library is synthesized for each scaffold.

    2016-01-01

    BACKGROUND: Cardiac rehabilitation (CR) is an evidence-based intervention to increase survival and quality of life. Yet studies consistently show that elderly patients are less frequently referred to CR, show less uptake and more often drop out of CR programmes. DESIGN: The European study...... home-based programme while the control group will receive no advice or coaching throughout the study period. Outcomes will be assessed after the end of CR and at 12 months follow-up. The primary outcome is VO2peak and secondary outcomes include variables describing CR uptake, adherence, efficacy...

    2012-04-15

    This paper describes the construction, operation and predictive modeling of a molecular machine, functioning as a high sensitivity biosensor. Embedded gramicidin A (gA) ionchannels in a self-assembled tethered lipid bilayer act as biological switches in response to target molecules and provide a signal amplification mechanism that results in high sensitivity molecular detection. The biosensor can be used as a rapid and sensitive point of care diagnostic device in different media such as human serum, plasma and whole blood without the need for pre and post processing steps required in an enzyme-linked immunosorbent assay. The electrical reader of the device provides the added advantage of objective measurement. Novel ideas in the construction of the molecular machine, including fabrication of biochip arrays, and experimental studies of its ability to detect analyte molecules over a wide range of concentrations are presented. Remarkably, despite the complexity of the device, it is shown that the response can be predicted by modeling the analyte fluid flow and surface chemical reactions. The derived predictive models for the sensing dynamics also facilitate determining important variables in the design of a molecular machine such as the ion channel lifetime and diffusion dynamics within the bilayer lipid membrane as well as the bio-molecular interaction rate constants.

    2017-05-31

    Despite growing pan-European interest in and awareness of the wide-ranging health and well-being impacts of energy poverty-which is characterised by an inability to secure adequate levels of energy services in the home-the knowledge base is largely British-centric and dominated by single-country studies. In response, this paper investigates the relationship between energy poverty, health and well-being across 32 European countries, using 2012 data from the European Quality of Life Survey. We find an uneven concentration of energy poverty, poor health, and poor well-being across Europe, with Eastern and Central Europe worst affected. At the intersection of energy poverty and health, there is a higher incidence of poor health (both physical and mental) amongst the energy poor populations of most countries, compared to non-energy poor households. Interestingly, we find the largest disparities in health and well-being levels between energy poor and non-energy poor households occur within relatively equal societies, such as Sweden and Slovenia. As well as the unique challenges brought about by rapidly changing energy landscapes in these countries, we also suggest the relative deprivation theory and processes of social comparison hold some value in explaining these findings.

    The relationship between coffee consumption and mortality in diverse European populations with variable coffee preparation methods is unclear. To examine whether coffee consumption is associated with all-cause and cause-specific mortality. Prospective cohort study. 10 European countries. 521 330 persons enrolled in EPIC (European Prospective Investigation into Cancer and Nutrition). Hazard ratios (HRs) and 95% CIs estimated using multivariable Cox proportional hazards models. The association of coffee consumption with serum biomarkers of liver function, inflammation, and metabolic health was evaluated in the EPIC Biomarkers subcohort (n = 14 800). During a mean follow-up of 16.4 years, 41 693 deaths occurred. Compared with nonconsumers, participants in the highest quartile of coffee consumption had statistically significantly lower all-cause mortality (men: HR, 0.88 [95% CI, 0.82 to 0.95]; P for trend coffee drinking with circulatory disease mortality (HR, 0.78 [CI, 0.68 to 0.90]; P for trend coffee consumption was associated with lower serum alkaline phosphatase; alanine aminotransferase; aspartate aminotransferase; γ-glutamyltransferase; and, in women, C-reactive protein, lipoprotein(a), and glycated hemoglobin levels. Reverse causality may have biased the findings; however, results did not differ after exclusion of participants who died within 8 years of baseline. Coffee-drinking habits were assessed only once. Coffee drinking was associated with reduced risk for death from various causes. This relationship did not vary by country.

    The paper shows the results on the relationship between zinc status, psychological dimensions (cognitive functions, mood, perceived stress) and nutritional aspects in European healthy old subjects recruited for ZINCAGE Project (supported by the European Commission in the Sixth Framework Programme). The old healthy subjects were recruited in Italy, Greece, Germany, France, Poland taking into account the different dietary habits between Northern and Southern European Countries and the pivotal role played by zinc for psychological functions. Measures of the cognitive status, mood and perceived stress level were obtained at baseline, using the "Mini Mental State Examination (MMSE)"; the "Geriatric Depression Scale (GDS - 15 items)" and the "Perceived Stress Scale (PSS)", respectively. Nutritional status was assessed using "Frequency Food Questionnaire". The sample included 853 old subjects, classified in 4 groups of age: 60-69-years-old (n = 359); 70-74-years-old (n = 225); 75-79-years-old (n = 153); 80-84-years-old (n = 116). Subjects were studied on the basis of plasma zinc, in which zinc cognitive decline, whereas 76% presented a low GDS value indicating no depression. However, all psychological variables were related to plasma zinc values and nutritional assessment. In particular, a relationship between marginal zinc deficiency and impaired psychological dimensions occurred in Greece than in other European countries due to low intake and less variety of foods rich of zinc. This phenomenon was independent by the age, suggesting that a correct zinc intake from a wide range of foods may be useful to maintain a satisfactory plasma zinc levels as well as psychological status in elderly with subsequent achievement of healthy ageing.

    We present an ab initio molecular dynamics study of siloxane elastomers placed under tensile stress for comparison with single molecule AFM experiments. Of particular interest is stress-induced chemical bond breaking in the high force regime, where a description of the molecular electronic structure is essential to determine the rupture mechanism. We predict an ionic mechanism for the bond breaking process with a rupture force of 4.4 nN for an isolated siloxane decamer pulled at a rate of 27.3 m/s and indicate lower values at experimental polymer lengths and pulling rates.

    2015-01-01

    It was reported that buffalo is a low susceptibility species resisting to TSEs (Transmissible Spongiform Encephalopathies) (same as rabbits, horses and dogs). TSEs, also called prion diseases, are invariably fatal and highly infectious neurodegenerative diseases that affect a wide variety of species (in humans prion diseases are (v)CJDs, GSS, FFI, and kulu etc). It was reported that buffalo is a low susceptibility species resisting to prion diseases (as rabbits, dogs, horses). In molecular structures, these neurodegenerative diseases are caused by the conversion from a soluble normal cellular prion protein, predominantly with alpha-helices, into insoluble abnormally folded infectious prions, rich in beta-sheets. This paper studies the molecular structure and structural dynamics of buffalo prion protein, in order to find out the reason why buffaloes are resistant to prion diseases. We first did molecular modeling a homology structure constructed by one mutation at residue 143 from the Nuclear Magnetic Resonanc...

    A molecular approach to information storage employs redox-active molecules tethered to an electroactive surface. Zinc porphyrins tethered to Au(111) or Si(100) provide a benchmark for studies of information storage. Three sets of porphyrins have been synthesized for studies of the interplay of molecular design and charge-storage properties: (1) A set of porphyrins is described for probing the effect of surface attachment atom on electron-transfer kinetics. Each porphyrin bears a meso-CH2X group for surface attachment where X = OH, SAc, or SeAc. (2) A set of porphyrins is described for studying the effect of surface-charge density in monolayers. Each porphyrin bears a benzyl alcohol for surface attachment and three nonlinking meso substituents of a controlled degree of bulkiness. (3) A set of porphyrins is described that enables investigation of on-chip patterning of the electrolyte. Each porphyrin bears a formyl group distal to the surface attachment group for subsequent derivatization with a molecular entity that comprises the electrolyte. Taken together, this collection of molecules enables a variety of studies to elucidate design issues in molecular-based information storage. Copyright 2004 American Chemical Society

    Full Text Available European Years are a means of promoting European issues at a macro and micro-level. The objective of this paper is to provide the visual differences in the framing of the issue of volunteering at a European and national level. The approach focuses on a blending of two qualitative research methods in visual communication: ATLAS.ti (computer assisted/ aided qualitative data analysis software and social semiotics. The results of our analysis highlight two network views on volunteering promoted through videos, a salience of transactional processes in the implementation of volunteering at a European and national level, and a classification of various types of social practices specific to Romania. This study provides an insight into the way in which two different qualitative methods may be combined in order to provide a visual representation and interpretation to a European issue.

    Full Text Available Abstract Background Mucormycosis has emerged as a rare but frequently fatal invasive fungal disease. Current knowledge on paediatric mucormycosis is based on case reports and small series reported over several decades. Contemporary data on a large cohort of patients is lacking. Methods Two large international registries (Zygomyco.net and FungiScope™ were searched for mucormycosis cases in ≤19 year-old patients. Cases enrolled between 2005 and 2014 were extracted, and dual entries in the two databases merged. Epidemiology, clinical characteristics, diagnostic procedures, therapeutic management and final outcome were recorded and analysed with SPSS v.12. Results Sixty-three unique cases (44 proven and 19 probable were enrolled from 15 countries (54 in European and 9 in non-European countries. Median age was 13 years [Interquartile Range (IQR 7.7] with a slight predominance (54.1 % of females. Underlying conditions were haematological malignancies (46 %, other malignancies (6.3 %, haematopoietic stem cell transplantation (15.9 %, solid organ transplantation, trauma/surgery and diabetes mellitus (4.8 % each and a variety of other diseases (7.9 %; in 9.5%, no underlying medical condition was found. Neutropenia was recorded in 46 % of the patients. The main sites of infection were lungs (19 %, skin and soft tissues (19 %, paranasal sinus/sino-orbital region (15.8 % and rhino-cerebral region (7.9 %. Disseminated infection was present in 38.1 %.

    The current lung cancer classification from the Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society has considerably changed the pathologic diagnosis of lung invasive adenocarcinoma, identifying disease subtypes with substantial implications for medical practice, such as clinical, radiological, molecular, and prognostic differences. We analyzed the differences in the genetic expression of adenocarcinoma subtypes according to the new classification. Microarray gene expression analysis was performed on a cohort of 29 adenocarcinoma patients treated at the Instituto Nacional de Cancerología of Mexico from 2008 to 2011. All patients had an available biopsy sample and were classified into 4 different subtypes of adenocarcinoma (2015 World Health Organization classification). Lepidic-predominant adenocarcinoma was the only pattern that exhibited a marked gene expression difference compared with other predominant histologic patterns, revealing genes with significant expression (P adenocarcinoma that could be used as a gene signature. The lepidic-predominant histologic pattern has a differential gene expression profile compared with all predominant histologic patterns. Additionally, we identified a gene expression signature of 13 genes that have a unique behavior in the lepidic histologic pattern; these 13 genes are candidates for follow-up studies for their potential use as biomarkers or therapeutic targets. Results from this study highlight the importance of the new Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society classification and exemplify the potential clinical implications of correlating histopathology with exclusive molecular beacons.

    While the effects of hydrophilic excipients in enhancing the dissolution rate of water-insoluble drugs have been validated, the underlying mechanism remains poorly understood, particularly at a molecular level. In this work, a combination of docking calculations and MD simulations was applied to investigate the molecular interactions between bicalutamide (BIC) and each of three excipients: lactose (LAC), hydroxypropyl methylcellulose (HPMC), and mannitol (MAN). The calculated results indicated that BIC interacted with HPMC and MAN mainly by Lennard-Jones (LJ) interactions but with LAC mainly by Coulomb (Coul) interactions. There was no hydrogen bond formed between BIC and excipient. It was shown that BIC/LAC had the biggest total solvent accessible surface area with the biggest hydrophilic area and formed the most hydrogen bonds between excipient and water. In addition to the structure analyses, BIC/LAC had both the lowest interaction energy between BIC and excipient and the lowest interaction energy between BIC/excipient and water. All these led to the best dissolution performance of BIC/LAC, which could correspond to the experimental results of dissolution test. The present study suggests that a combination of docking calculations and MD simulations, which aims at complementing the experimental work, could provide a molecular insight into the interaction between drug and excipient. It also holds the great potential to simplify the optimization process of drug delivery system and reduce both time and costs.

    We discuss the features of a three-terminal molecular device and the control of electric current using a gate terminal. We introduce a capacitance model to investigate the effect of the gate terminal that could reduce to a two-terminal molecule for a very small gate capacitance. Therefore, this capacitance model can be used in the framework of ordinary ab initio quantum chemical methods. We show the effect of the gate terminal analytically using a simple Hückel method. Moreover, we used our capacitance model with a nonequilibrium Green's function (NEGF)-based Hartree-Fock (HF) approach to study the gate control features of the benzenedithiolate molecule, and we show that the current through the molecule can be modulated by the gate voltage in the case of a high gate control parameter. We also discuss the molecule's response to the applied bias voltage. It is found that the molecular charging effect has a strong influence on the behavior of molecular-based electronic devices.

    An original formulation of the relativistic molecular rotational g-tensor valid for heavy atom containing compounds is presented. In such formulation, the relevant terms of a molecular Hamiltonian for non-relativistic nuclei and relativistic electrons in the laboratory system are considered. Terms linear and bilinear in the nuclear rotation angular momentum and an external uniform magnetic field are considered within first and second order (relativistic) perturbation theory to obtain the rotational g-tensor. Relativistic effects are further analyzed by carrying out the linear response within the elimination of the small component expansion. Quantitative results for model systems HX (X=F, Cl, Br, I), XF (X=Cl, Br, I), and YH{sup +} (Y=Ne, Ar, Kr, Xe, Rn) are obtained both at the RPA and density functional theory levels of approximation. Relativistic effects are shown to be small for this molecular property. The relation between the rotational g-tensor and susceptibility tensor which is valid in the non-relativistic theory does not hold within the relativistic framework, and differences between both molecular parameters are analyzed for the model systems under study. It is found that the non-relativistic relation remains valid within 2% even for the heavy HI, IF, and XeH{sup +} systems. Only for the sixth-row Rn atom a significant deviation of this relation is found.

    2013-09-01

    The aim of the present study was to estimate the associations between the prevalence of asthma symptoms in schoolchildren and meteorological variables in west European countries that participated in the International Study of Asthma and Allergies in Children (ISAAC), Phase III 1997-2003. An ecologic study was carried out. The prevalence of asthma was obtained from this study from 48 centers in 14 countries, and meteorological variables from those stations closest to ISAAC centers, together with other socioeconomic and health care variables. Multilevel mixed-effects linear regression models were used. For schoolchildren aged 6-7 years, the prevalence rate of asthma decreased with an increase in mean annual sunshine hours, showed a positive association with rainy weather, and warm temperature, and a negative one with relative humidity and physician density (PD). Current wheeze prevalence was stronger in autumn/winter seasons and decreased with increasing PD. Severe current wheeze decreased with PD. For schoolchildren aged 13-14 years, the prevalence rates of asthma and current wheeze increased with rainy weather, and these rates decreased with increased PD. Current wheeze, as measured by a video questionnaire, was inversely associated with sunny weather, and nurse density. Severe current wheeze prevalence was stronger during autumn/winter seasons, decreased with PD, and indoor chlorinated public swimming pool density, and increased with rainy weather. Meteorological factors, including sunny and rainy weather, and PD may have some effect on the prevalence rates of asthma symptoms in children from west European countries.

    Genetic counsellors have been working in some European countries for at least 30 years. Although there are great disparities between the numbers, education, practice and acceptance of these professionals across Europe, it is evident that genetic counsellors and genetic nurses in Europe are working autonomously within teams to deliver patient care. The aim of this study was to use the Delphi research method to develop a core curriculum to guide the educational preparation of these professionals in Europe. The Delphi method enables the researcher to utilise the views and opinions of a group of recognised experts in the field of study; this study consisted of four phases. Phases 1 and 4 consisted of expert workshops, whereas data were collected in phases 2 and 3 (n=35) via online surveys. All participants in the study were considered experts in the field of genetic counselling. The topics considered essential for genetic counsellor training have been organised under the following headings: (1) counselling; (2) psychological issues; (3) medical genetics; (4) human genetics; (5) ethics, law and sociology; (6) professional practice; and (7) education and research. Each topic includes the knowledge, skills and attitudes required to enable genetic counsellors to develop competence. In addition, it was considered by the experts that clinical practice should comprise 50% of the educational programme. The core Master programme curriculum will enable current courses to be assessed and inform the design of future educational programmes for European genetic counsellors.

    This study aimed to identify and prioritise neonatal intensive care nursing research topics across Europe using an e-Delphi technique. An e-Delphi technique with three questionnaire rounds was performed. Qualitative responses of round one were analysed by content analysis and research statements were generated to be ranged on importance on a scale of 1-6 (not important to most important). Neonatal intensive care units (NICUs) in 17 European countries. NICU clinical nurses, managers, educators and researchers (n=75). None. A list of 43 research statements in eight domains. The six highest ranking statements (≥5.0 mean score) were related to prevention and reduction of pain (mean 5.49; SD 1.07), medication errors (mean 5.20; SD 1.13), end-of-life care (mean 5.05; SD 1.18), needs of parents and family (mean 5.04; SD 1.23), implementing evidence into nursing practice (mean 5.02; SD 1.03), and pain assessment (mean 5.02; SD 1.11). The research domains were prioritised and ranked: (1) pain and stress; (2) family centred care; (3) clinical nursing care practices; (4) quality and safety; (5) ethics; (6) respiratory and ventilation; (7) infection and inflammation; and (8) professional issues in neonatal intensive care nursing. The results of this study might support developing a nursing research strategy for the nursing section of the European Society of Paediatric and Neonatal Intensive Care. In addition, this may promote more European researcher collaboratives for neonatal nursing research. Published by the BMJ Publishing Group Limited.

    Although atmospheric 222radon (222Rn) activity concentration measurements are currently performed worldwide, they are being made by many different laboratories and with fundamentally different measurement principles, so compatibility issues can limit their utility for regional-to-global applications. Consequently, we conducted a European-wide 222Rn / 222Rn progeny comparison study in order to evaluate the different measurement systems in use, determine potential systematic biases between them, and estimate correction factors that could be applied to harmonize data for their use as a tracer in atmospheric applications. Two compact portable Heidelberg radon monitors (HRM) were moved around to run for at least 1 month at each of the nine European measurement stations included in this comparison. Linear regressions between parallel data sets were calculated, yielding correction factors relative to the HRM ranging from 0.68 to 1.45. A calibration bias between ANSTO (Australian Nuclear Science and Technology Organisation) two-filter radon monitors and the HRM of ANSTO / HRM = 1.11 ± 0.05 was found. Moreover, for the continental stations using one-filter systems that derive atmospheric 222Rn activity concentrations from measured atmospheric progeny activity concentrations, preliminary 214Po / 222Rn disequilibrium values were also estimated. Mean station-specific disequilibrium values between 0.8 at mountain sites (e.g. Schauinsland) and 0.9 at non-mountain sites for sampling heights around 20 to 30 m above ground level were determined. The respective corrections for calibration biases and disequilibrium derived in this study need to be applied to obtain a compatible European atmospheric 222Rn data set for use in quantitative applications, such as regional model intercomparison and validation or trace gas flux estimates with the radon tracer method.

    The World Health Organization has identified developing the knowledge and skills of healthcare professionals who are involved in dementia care as a priority. Most healthcare professionals lack the necessary knowledge, skills and understanding to provide high quality dementia care. While dementia education amongst most UK university health and social care programmes is inconsistent, we know little about the provision of dementia education in European universities. To examine the provision of accredited higher education on dementia in European countries, to illustrate that it is highly variable despite universities being the major provider of education for healthcare professionals internationally. An exploratory research design was used. The providers of higher education undergraduate and postgraduate programmes in the Czech Republic, Portugal, Scotland, Slovenia, Spain, Sweden. Higher Education Institutions who provide undergraduate and postgraduate education in the fields of nursing, medicine, psychology, social work, physiotherapy, occupational therapy, and gerontology in six European countries. The data was collected using a structured questionnaire. Researchers in each country conducted an internet-based search using the websites of Higher Education Institutions to identify existing accredited dementia education. These searches revealed a lack of dementia education in undergraduate health and social care study programmes. Three of the six countries offered postgraduate study programmes on dementia. There was a significant variation amongst the countries in relation to the provision of dementia education at undergraduate, postgraduate and doctoral levels. Dementia is a global challenge and educating and upskilling the workforce is a policy imperative. To deliver the best dementia care, investment in interprofessional evidence-based education is required if we are to respond effectively and compassionately to the needs of people living with dementia and their

    Full Text Available Scardinius is a genus of ray-finned fish in the Cyprinidae family commonly called rudds. The common rudd(Scardinius erithrophthalmus is a bentho-pelagic freshwater fish that occurs mainly in nutrient-rich, well vegetatedlowland rivers, backwaters, oxbows, ponds and lakes and it is widespread in Europe and middle Asia. It has a mediumlength of 20-30 cm, but it can reach 50 cm. The classification of cyprinids has always been controversial the morphologicaltraits have an unclear homology this led to the idea that the recognized monophyletic groups are surely misinterpreted. Thispaper aims to assess the current level of molecular data regarding Scardinius genera. Some of the molecular data obtainedfor Scardinius genus is from DNA barcoding studies on fresh water fishes, but studies regarding this genus and Cyprinidaefamily used mitochondrial genes like cytochrome b (cyt b and cytochrome oxidase (CO, but nuclear genes or nuclearmicrosatellites were also used. We found that molecular data exists for both nuclear and mitochondrial genes, but this genuswasn’t studied separately and as many of the researchers suggest more taxonomic studies are required in order to solve theuncertainties within it.

    Full Text Available Existing research on undocumented migration has focused predominantly on Latin American and Mexican immigrants and largely overlooked the experiences of immigrants originating from other parts of the world. As such, very few studies have considered how the lack of legal residency status can influence life opportunities of undocumented immigrants from Eastern Europe. The overarching aim of the present study was to explore the personal experiences of unauthorized Eastern European immigrants in the United States in order to: (a augment research on undocumented migration, and (b highlight the experiences of undocumented Eastern Europeans who remain an understudied group of the undocumented immigrants. Comprehensive personal interviews were conducted with a small group of unauthorized immigrants to explore: (1 reasons for immigration and prior expectations, and (2 psychosocial experiences (i.e., status related anxiety, experience with prejudice and discrimination, job satisfaction, sense of belonging, family relations, and future plans. Some of the results are presented in terms of similarity and differences between the current study's sample and the undocumented immigrants from other regions of the world, namely, Mexico and Latin America.

    The presence of noncutaneous neoplasms does not seem to increase the risk of cutaneous malignant melanoma; however, it seems to be associated with the development of other hematological, brain, breast, uterine, and prostatic neoplasms. An ecological transversal study was conducted to study the geographic association between cutaneous malignant melanoma and 24 localizations of cancer in forty European countries. Cancer incidence rates were extracted from GLOBOCAN database of the International Agency for Research on Cancer. We analyzed the age-adjusted and gender-stratified incidence rates for different localizations of cancer in forty European countries and calculated their correlation using Pearson's correlation test. In males, significant correlations were found between cutaneous malignant melanoma with testicular cancer (r = 0.83 [95% confidence interval (CI): 0.68-0.89]), myeloma (r = 0.68 [95% CI: 0.46-0.81]), prostatic carcinoma (r = 0.66 [95% CI: 0.43-0.80]), and non-Hodgkin lymphoma (NHL) (r = 0.63 [95% CI: 0.39-0.78]). In females, significant correlations were found between cutaneous malignant melanoma with breast cancer (r = 0.80 [95% CI: 0.64-0.88]), colorectal cancer (r = 0.72 [95% CI: 0.52-0.83]), and NHL (r = 0.71 [95% CI: 0.50-0.83]). These correlations call to conduct new studies about the epidemiology of cancer in general and cutaneous malignant melanoma risk factors in particular.

    Fish is a rich source of essential nutrients for fetal development, but in contrast, it is also a well-known route of exposure to environmental pollutants. We assessed whether fish intake during pregnancy is associated with fetal growth and the length of gestation in a panel of European birth cohort studies. The study sample of 151,880 mother-child pairs was derived from 19 population-based European birth cohort studies. Individual data from cohorts were pooled and harmonized. Adjusted cohort-specific effect estimates were combined by using a random- and fixed-effects meta-analysis. Women who ate fish >1 time/wk during pregnancy had lower risk of preterm birth than did women who rarely ate fish (≤ 1 time/wk); the adjusted RR of fish intake >1 but fish during pregnancy gave birth to neonates with a higher birth weight by 8.9 g (95% CI: 3.3, 14.6 g) for >1 but fish intake during pregnancy is associated with lower risk of preterm birth and a small but significant increase in birth weight.

    Alien species invasion is one of the most important drivers of worldwide environmental change, which may result in environmental degradation, biodiversity loss, and food and water shortage. It may also increase the possibility and severity of natural disasters, and damage international trade and benefits. In last two decades, DNA-based molecular markers were widely used to detect the genetic diversity of invaded alien species. Inter-simple sequence repeat (ISSR) is a microsatellite-based technique, with the superiorities of simple, quick, reliable, and generating higher levels of DNA polymorphism, and being used as a new molecular marker for genetic study. This paper introduced the principles, characteristics and procedures of ISSR, and summarized its applications in studying the genetic structure, genetic diversity, origin, distribution mode, phylogenesis, and breeding features of invasive plants.

  16. Molecular taxonomy of phytopathogenic fungi: a case study in Peronospora.

    Directory of Open Access Journals (Sweden)

    Markus Göker

    Full Text Available BACKGROUND: Inappropriate taxon definitions may have severe consequences in many areas. For instance, biologically sensible species delimitation of plant pathogens is crucial for measures such as plant protection or biological control and for comparative studies involving model organisms. However, delimiting species is challenging in the case of organisms for which often only molecular data are available, such as prokaryotes, fungi, and many unicellular eukaryotes. Even in the case of organisms with well-established morphological characteristics, molecular taxonomy is often necessary to emend current taxonomic concepts and to analyze DNA sequences directly sampled from the environment. Typically, for this purpose clustering approaches to delineate molecular operational taxonomic units have been applied using arbitrary choices regarding the distance threshold values, and the clustering algorithms. METHODOLOGY: Here, we report on a clustering optimization method to establish a molecular taxonomy of Peronospora based on ITS nrDNA sequences. Peronospora is the largest genus within the downy mildews, which are obligate parasites of higher plants, and includes various economically important pathogens. The method determines the distance function and clustering setting that result in an optimal agreement with selected reference data. Optimization was based on both taxonomy-based and host-based reference information, yielding the same outcome. Resampling and permutation methods indicate that the method is robust regarding taxon sampling and errors in the reference data. Tests with newly obtained ITS sequences demonstrate the use of the re-classified dataset in molecular identification of downy mildews. CONCLUSIONS: A corrected taxonomy is provided for all Peronospora ITS sequences contained in public databases. Clustering optimization appears to be broadly applicable in automated, sequence-based taxonomy. The method connects traditional and modern

The acoustic response of the system to loading is evaluated as forces acting on sensors which represent separate atomic areas located on the specimen surface. The analysis of acoustic emission and internal specimen structure shows a significant change in the emission signal due to the emergence of dislocations on the specimen surface.

    Full Text Available In an era of increased globalisation, the need for a sense of belonging and an identity is becoming more pressing. The way nations form images of others and, conversely, conscious or unconscious images of themselves is becoming increasingly important as these images impact on public opinion and on political and decision-making discourse. With the development of supranationalism in Europe, the age-old notion of European identity has come more and more to the fore. Conflicting interpretations and a general disinclination to consider the matter leave the notion of European identity as polysemic as ever. Furthermore, the expansion of the EU has contributed to blurring this notion, so much so that in the collective psyche, it has become closely linked to the membership of the European Union and it is proving sometimes difficult to dissociate one from the other. In this context, the debate surrounding Turkey’s membership of the EU gives an insight into prototypical and stereotypical representations of Europe. As the controversy has been particularly salient in France, the aim of this study is to explore the European self-conceptions and images of the other through the example of France’s opposition to Turkey’s membership of the EU. For this purpose, opinion polls and the Press will be used as forms of narrative in order to highlight these representations and how they have evolved in time. The first part of the study will concentrate on the arguments put forward to justify the opposition to Turkey joining the EU. The second part will then evaluate how the image of the other contributes to the prototypical representation French citizens have of Europe.

    Diseases caused by Streptococcus pneumoniae (pneumococcus) are a major global public health problem. Despite their importance, information on the burden of the different pneumococcal diseases is limited and estimates vary widely. We critically reviewed the full economic evaluations (FEEs) on the new pneumococcal conjugate vaccines (PCVs) conducted in the European Union (EU) to assess their potential contribution to public decision making. We selected the FEEs focussed on PCV-10 and PCV-13 and published in English from January 2007 until June 2013. We screened the selected articles to assess their main methodological features using a common checklist composed of epidemiological, clinical and economic items. All the ten studies selected were based on modelling and the time horizon was always long term. Two studies focused on adults, the remaining eight on infants. Only one study based herd immunity on national data, eight used foreign data or modelling and the last did not consider it. National prices and tariffs were claimed to be sources for unit costs in all studies; however, half of them assumed price parity when one vaccine was not yet marketed, and the figures varied within the countries where more than one study was conducted. Conclusions supported the economic utility of pneumococcal vaccination in all studies, raising some concern only in (i) the independent study, which found that PCV-13 was borderline cost effective, and (ii) the study sponsored by both manufacturers, which estimated an incremental ratio slightly above the national threshold for both PCV-10 and PCV-13. The European studies we analysed are mostly based on weak sources of data. Because of the limited information on vaccine effectiveness and lack of epidemiological and economic data, the need for extensive recourse to assumptions leads to great within- and between-study variability generated by authors' choices.

    The clinical progression of Alzheimer disease (AD) was studied in European subjects under treatment with AChE inhibitors (AChE-I) in relation to geographical location over a 2-years period. One thousand three hundred and six subjects from 11 European countries were clustered into 3 regions (North, South, West) and investigated with biannual follow-up over 2 years. Primary outcomes were cognitive, functional and behavioral measures. Caregiver burden, hospital admission and admission to nursing home were also recorded. Participant cognitive function declined non-linearly over time (MMSE: -1.5 pts/first year, -2.5 pts/second year; ADAScog: + 3.5 pts/first year, + 4.8 pts/second year), while the progression of behavioral disturbances (NPI scale) was linear. Neither scale showed regional differences, and progression of the disease was similar across Europe despite different health care systems. Functional decline (ADL, IADL) tended to progress more rapidly in Southern Europe (p=0.09), while progression of caregiver burden (Zarit Burden Interview) was most rapid in Northern Europe (5.6 pts/y, p=0.04). Incidences of hospital admission (10.44, 95%CI: 8.13-12.75, p < 0.001) and admission to nursing home (2.97, 95%CI: 1.83-4.11, p < 0.001) were lowest in Southern Europe. In general cognitive and functional decline was slower than in former cohorts. European geographical location reflecting differences in culture and in health care system does not impact on the progression of AD but does influence the management of AD subjects and caregiver burden.

    FT-IR and FT-Raman spectra of 5-nitro-2-phenoxymethylbenzimidazole were recorded and analyzed theoretically and experimentally. The splitting of Nsbnd H stretching mode in the IR spectrum with a red shift from the calculated value indicates the weakening of the NH bond. The theoretical calculations give the phenyl ring breathing modes at 999 cm-1 for mono substituted benzene ring and at 1040 cm-1 for tri-substituted benzene ring. The theoretical NMR chemical shifts are in agreement with the experimental chemical shifts. The most reactive sites for electrophilic and nucleophilic attack are predicted from the MEP analysis. HOMO of π nature is delocalized over the entire molecule whereas the LUMO is located over the complete molecule except mono-substituted phenyl ring and oxygen atom. Reactive sites of the title molecule have been located with the help of ALIE surfaces and Fukui functions. In order to determine locations prone to autoxidation and locations interesting for starting of degradation, bond dissociation energies have been calculated for all single acyclic bonds. For the determination of atoms with pronounced interactions with water we have calculated radial distribution functions obtained after molecular dynamics simulations. The calculated first hyperpolarizability of the title compound is 58.03 times that of standard nonlinear optical material urea. The substrate binding site interactions of the title compound with Topo II enzyme is reported by using molecular docking study. Biological activity studies show that the title compound can be leaded for developing new anticancer agents.

    Cutaneous leishmaniasis (CL) is a major public health problem in Libya. The objective of this study was to investigate, for the first time, epidemiological features of CL outbreaks in Libya including molecular identification of parasites, the geographical distribution of cases and possible scenarios of parasite transmission. We studied 450 patients that came from 49 areas distributed in 12 districts in north-west Libya. The patients' ages ranged from 9 months to 87 years (median age 25 years); 54% of the cases were males. Skin scrapings spotted on glass slides were collected for molecular identification of causative agent. The ribosomal internal transcribed spacer 1 (ITS1) was amplified and subsequently characterized by restriction fragment length polymorphism (RFLP) analysis. In total, 195 samples were successfully identified of which 148 (75.9%) were Leishmania major, and 47 (24.1%) Leishmania tropica. CL cases infected with L. major were found in all CL areas whereas L. tropica cases came mainly from Al Jabal Al Gharbi (46.4%), Misrata (17.8%) and Tarhuna districts (10.7%). A trend of seasonality was noticed for the infections with L. major which showed a clear peak between November and January, but was less pronounced for infections by L. tropica. The first molecular study on CL in Libya revealed that the disease is caused by L. major and L. tropica and the epidemiological patterns in the different foci were the same as in other Mediterranean foci of CL.

    The risk of psychological disorders influencing the health of workers increases in accordance with growing requirements on employees across various professions. This study aimed to compare approaches to the burnout syndrome in European countries. A questionnaire focusing on stress-related occupational diseases was distributed to national experts of 28 European Union countries. A total of 23 countries responded. In 9 countries (Denmark, Estonia, France, Hungary, Latvia, Netherlands, Portugal, Slovakia and Sweden) burnout syndrome may be acknowledged as an occupational disease. Latvia has burnout syndrome explicitly included on the List of ODs. Compensation for burnout syndrome has been awarded in Denmark, France, Latvia, Portugal and Sweden.Only in 39% of the countries a possibility to acknowledge burnout syndrome as an occupational disease exists, with most of compensated cases only occurring in recent years. New systems to collect data on suspected cases have been developed reflecting the growing recognition of the impact of the psychosocial work environment. In agreement with the EU legislation, all EU countries in the study have an action plan to prevent stress at the workplace.

    Consumer perception of the healthiness of beef is an important determinant of beef consumption. However, little is known about how consumers perceive the healthiness of beef. The aim of this study is to shed light on the associations between beef and health. Eight focus group discussions were conducted in four European countries (France, UK, Germany, Spain), each consisting of seven to nine participants. A content analysis was performed on the transcripts of these discussions. Although beef was generally perceived as healthful, focus group participants expected positive as well as negative effects of beef consumption on their health. Labelled, branded, fresh and lean beef were perceived as signalling healthful beef, in contrast with further processed and packaged beef. Consumers felt that their individual choices could make a difference with respect to the healthiness of beef consumed. Focus group participants were not in favour of improving beef healthiness during processing, but rather focussed on appropriate consumption behaviour and preparation methods. The individual responsibility for health implies that consumers should be able to make correct judgements about how healthful their food is. However, the results of this study indicate that an accurate assessment of beef healthiness is not always straightforward. The presented results on consumer perceptions of beef healthiness provide insights into consumer decision making processes, which are important for the innovation and product differentiation in the European beef sector, as well as for public health policy decisions related to meat consumption in general and beef consumption in particular.

The paper will be structured into three parts so that the study will begin to clarify the notion of competece, then determining the place and role of local communities-we will identify common features and criteria for their differentiation.Given this objective we propose to realise a comparative study of local collectivities skills in Europe, to identify their relationship with the State. The conducted research continues others concerning the timeliness of this research in the theoretical plan, therefore the following are necesary: establishing the place and role, definition and identification of its legal nature, emphasizing key features of the functions and criteria in relation with the State. The work may be useful to the Romanian authorities involved in the enforcement of local collectivities in the context of decentralization. The results and the essential contribution of the work, its originality, consist of the general examination of the categories of local collectivities elected for representation and the diversity of european experiences, regarding the local administrative device -organizatoric forms, in federal states, decentralized unitary states and unitary states partial or non-centralized.

    International partnerships are a mechanism for supporting the academic development of occupational therapy and promoting cultural competence. This case study describes the factors that have helped to sustain a post-qualifying programme implemented by five higher education institutions in Denmark, the Netherlands, Sweden, Switzerland and the UK since 1999. Data collection methods were documentary analysis and the reflections of a purposive sample of six key informants. Cohort and outcome data, from 193 students from 31 countries who enrolled between 1999 and 2011, are reported. Each cohort comprises students from an average of eight countries to optimize inter-cultural dialogue. Four factors support sustainability. These are 1) supportive professional European networks; 2) timeliness and alignment with European higher education policy; 3) partnership structures and processes that emphasize joint decision making and accountability; and 4) the stimulus and satisfaction associated with internationalization. The main limitations are considering the OT-EuroMaster as an intrinsic case study and using opportunistic data collection that undermines the rigor and transferability of the findings. Future opportunities include doctoral networks, transnational research and sharing our curricula design with other Regions to spread the collaborative, capacity building endeavours more widely.

    The identification of isolation signatures is fundamental to better understand the genetic structure of human populations and to test the relations between cultural factors and genetic variation. However, with current approaches, it is not possible to distinguish between the consequences of long-term isolation and the effects of reduced sample size, selection and differential gene flow. To overcome these limitations, we have integrated the analysis of classical genetic diversity measures with a Bayesian method to estimate gene flow and have carried out simulations based on the coalescent. Combining these approaches, we first tested whether the relatively short history of cultural and geographical isolation of four “linguistic islands” of the Eastern Alps (Lessinia, Sauris, Sappada and Timau) had left detectable signatures in their genetic structure. We then compared our findings to previous studies of European population isolates. Finally, we explored the importance of demographic and cultural factors in shaping genetic diversity among the groups under study. A combination of small initial effective size and continued genetic isolation from surrounding populations seems to provide a coherent explanation for the diversity observed among Sauris, Sappada and Timau, which was found to be substantially greater than in other groups of European isolated populations. Simulations of micro-evolutionary scenarios indicate that ethnicity might have been important in increasing genetic diversity among these culturally related and spatially close populations.

  11. Study of percolation behavior depending on molecular structure design

    Science.gov (United States)

    Yu, Ji Woong; Lee, Won Bo

    Each differently designed anisotropic nano-crystals(ANCs) are studied using Langevin dynamic simulation and their percolation behaviors are presented. Popular molecular dynamics software LAMMPS was used to design the system and perform the simulation. We calculated the minimum number density at which percolation occurs(i.e. percolation threshold), radial distribution function, and the average number of ANCs for a cluster. Electrical conductivity is improved when the number of transfers of electrons between ANCs, so called ''inter-hopping process'', which has the considerable contribution to resistance decreases and the number of inter-hopping process is directly related with the concentration of ANCs. Therefore, with the investigation of relationship between molecular architecture and percolation behavior, optimal design of ANC can be achieved.

  12. A molecular density functional theory to study solvation in water

    CERN Document Server

    Jeanmairet, Guillaume

    2014-01-01

    A classical density functional theory is applied to study solvation of solutes in water. An approx- imate form of the excess functional is proposed for water. This functional requires the knowledge of pure solvent direct correlation functions. Those functions can be computed by using molecular simulations such as molecular dynamic or Monte Carlo. It is also possible to use functions that have been determined experimentally. The functional minimization gives access to the solvation free energy and to the equilibrium solvent density. Some correction to the functional are also proposed to get the proper tetrahedral order of solvent molecules around a charged solute and to reproduce the correct long range hydrophobic behavior of big apolar solutes. To proceed the numerical minimization of the functional, the theory has been discretized on two tridimensional grids, one for the space coordinates, the other for the angular coordinates, in a functional minimization code written in modern Fortran, mdft. This program i...

    1993-07-01

    Goal is to study the organization and structures of guest atoms and molecules and their reactions on internal surfaces within pores of zeolites and aluminophosphate molecular sieves. 27Al and 23Na double rotation NMR (DOR) is used since it removes the anisotropic broadening in NMR spectra of quadrupolar nuclei, thus increasing resolution. This work concentrates on probing aluminum framework atoms in aluminophosphate molecular sieves and sodium extra framework cations in porous aluminosilicates. In aluminophosphates, ordering and electronic environments of the framework 27Al nuclei are modified upon adsorption of water molecules within the channels; a relation is sought between the sieve channel topology and the organization of adsorbed water, as well as the interaction between the Al nuclei and the water molecules. Extra framework Na+ cations are directly involved in adsorption processes and reactions in zeolite cavities.

    Full Text Available Human T-cell leukemia virus type 1 (HTLV-1 was the first human retrovirus discovered. Studies on HTLV-1 have been instrumental for our understanding of the molecular pathology of virus-induced cancers. HTLV-1 is the etiological agent of an adult T-cell leukemia (ATL and can lead to a variety of neurological pathologies, including HTLV-1-associated-myelopathy/tropical spastic paraparesis (HAM/TSP. The ability to treat the aggressive ATL subtypes remains inadequate. HTLV-1 replicates by (1 an infectious cycle involving virus budding and infection of new permissive target cells and (2 mitotic division of cells harboring an integrated provirus. Virus replication initiates host antiviral immunity and the checkpoint control of cell proliferation, but HTLV-1 has evolved elegant strategies to counteract these host defense mechanisms to allow for virus persistence. The study of the molecular biology of HTLV-1 replication has provided crucial information for understanding HTLV-1 replication as well as aspects of viral replication that are shared between HTLV-1 and human immunodeficiency virus type 1 (HIV-1. Here in this review, we discuss the various stages of the virus replication cycle—both foundational knowledge as well as current updates of ongoing research that is important for understanding HTLV-1 molecular pathogenesis as well as in developing novel therapeutic strategies.

    Full Text Available Community support and participation among persons with disabilities. A study in three European countriesThis article describes a European project which was aimed at improving the situation of persons with psychiatric or learning disabilities with regard to social participation and citizenship. The project took place in three countries (Estonia, Hungary and the Netherlands and four cities (Tallinn, Budapest, Amersfoort and Maastricht. The project included research and actions at the policy level, the organizational level and the practice level. At the policy level, the framework of the United Nations Convention on the Rights of Persons with Disabilities (United Nations, 2006 and the European Disability Strategy (European Commission, 2010 were used to look at national and local policies, at the reality of the lives of those with disabilities and at the support that professional services offer with regard to participation and inclusion. The project generated a number of insights, recommendations and methods by which to improve the quality of service and increase the number of opportunities for community engagement. In this article, we present some of the lessons learned from the meta-analysis. Although the circumstances in each country are quite different with regard to policy, culture and service systems, it is remarkable that people with disabilities face many of the same problems.The study shows that in all three countries, access to services could be improved. Barriers include bureaucratic procedures and a lack of services. The research identified that in every country and city there are considerable barriers regarding equal participation in the field of housing, work and leisure activities. In addition to financial barriers, there are the barriers of stigma and self-stigmatization. Marginalization keeps people in an unequal position and hinders their recovery and participation. In all countries, professionals need to develop a stronger focus

    Full Text Available This study aimed to evaluate the overall satisfaction determinants of the student’s body of a higher education institution in the northwest of Rio Grande do Sul/Brasil. To do so, a descriptive quantitative research was performed, which used a model based on a Survey with 402 students, being the instrument used to conduct the survey based on the European model of satisfaction. Represented by a structural equation (PASWAN YOUNG, 2002, apud VIEIRA et al., 2008, the ECSI (European Customer Satisfaction Model, focuses on: (i evaluating the influence of perceived quality, the expectation of quality, image and perceived value in the overall student satisfaction; (II evaluating the influence of the general satisfaction of students in the level of loyalty and retention of students in the educational institution, and (III pointing key areas as well as a set of indicators for the management and maintenance of the students’ satisfaction from the institution being analyzed. Thus, with the application of the instrument, three factors able to explain 78% of student’s satisfaction towards the university were found: the first and most representative factor was called the student perceived value, which is the perceived value or level of teaching quality for the price paid by the students, the second factor is the image of the university, and the third factor are the expectations of the student.

    To identify and to establish research priorities for pediatric intensive care nursing science across Europe. A modified three-round electronic Delphi technique was applied. Questionnaires were translated into seven different languages. European PICUs. The participants included pediatric intensive care clinical nurses, managers, educators, and researchers. In round 1, the qualitative responses were analyzed by content analysis and a list of research statements and domains was generated. In rounds 2 and 3, the statements were ranked on a scale of one to six (not important to most important). Mean scores and SDs were calculated for rounds 2 and 3. None. Round 1 started with 90 participants, with round 3 completed by 64 (71%). The seven highest ranking statements (≥ 5.0 mean score) were related to end-of-life care, decision making around forgoing and sustaining treatment, prevention of pain, education and competencies for pediatric intensive care nurses, reducing healthcare-associated infections, identifying appropriate nurse staffing levels, and implementing evidence into nursing practice. Nine research domains were prioritized, and these were as follows: 1) clinical nursing care practices, 2) pain and sedation, 3) quality and safety, 4) respiratory and mechanical ventilation, 5) child- and family-centered care, 6) ethics, 7) professional issues in nursing, 8) hemodynamcis and resuscitation, and 9) trauma and neurocritical care. The results of this study inform the European Society of Pediatric and Neonatal Intensive Care's nursing research agenda in the future. The results allow nurse researchers within Europe to encourage collaborative initiatives for nursing research.

Flexibility, muscular fitness, speed/agility and aerobic capacity were tested using the back-saver sit and reach, handgrip, standing broad jump, Bosco jumps (squat jump, counter movement jump and Abalakov jump), bent arm hang, 4 x 10 m shuttle run, and 20-m shuttle run tests. The ANOVA analysis showed that neither systematic bias nor sex differences were found for any of the studied tests, except for the back-saver sit and reach test, in which a borderline significant sex difference was observed (P=0.044). The Bland-Altman plots graphically showed the reliability patterns, in terms of systematic errors (bias) and random error (95% limits of agreement), of the physical fitness tests studied. The observed systematic error for all the fitness assessment tests was nearly 0. Neither a learning nor a fatigue effect was found for any of the physical fitness tests when repeated. The results also suggest that reliability did not differ between male and female adolescents. Collectively, it can be stated that the reliability of the set of physical fitness tests examined in this study is acceptable. The data provided contribute to a better understanding of physical fitness assessment in young people.

    Full Text Available Bacillus anthracis es una de las bacterias más monomórficas conocidas y los estudios epidemiológicos de este microorganismo se han visto dificultados por la falta de marcadores moleculares. El objetivo de este trabajo fue caracterizar molecularmente catorce cepas de campo argentinas y la cepa vacunal Sterne 34F2 sobre la base del estudio del locus vrrA, que contiene una repetición en tándem de número variable (VNTR y presenta un polimorfismo con cinco variantes. También se ha tenido en cuenta la presencia o ausencia de los plásmidos de virulencia. Las cepas fueron aisladas de vacas, ovejas y cerdos durante brotes ocurridos en Buenos Aires, Entre Ríos, Santa Fe y La Pampa durante los últimos cincuenta años. Todas las cepas de campo presentaron los plásmidos pXO1 y pXO2, con excepción de una cepa aislada de cerdo que únicamente presentó el plásmido pXO2. Todos los aislamientos y la cepa vacunal pertenecieron a la misma variante molecular de VNTR, que se definió secuenciando el locus vrrA de tres de los aislamientos y de la cepa 34F2. Estas secuencias fueron completamente idénticas y correspondieron a la variante VNTR4; así, las catorce cepas argentinas de B. anthracis estudiadas mostraron una gran uniformidad a nivel molecular, aun cuando se habían aislado de diferentes especies de mamíferos, en un amplio período de tiempo y en una extensa zona geográfica.Bacillus anthracis is one of the most monomorphic bacteria known and epidemiological studies of this microorganism have been hampered by the lack of molecular markers. For the genotyping of fourteen Argentine field strains and the vaccine strain Sterne 34F2, the presence or absence of the virulence plasmids as well as vrrA locus containing a variable-number tandem repeat (VNTR and presenting a polymorphism involving five variants, were analyzed. Strains were isolated from cows, sheep and pigs during outbreaks occurred in Buenos Aires, Entre Ríos, Santa Fe and La Pampa in

    International consensus recognises four medulloblastoma molecular subgroups: WNT (MBWNT), SHH (MBSHH), group 3 (MBGrp3), and group 4 (MBGrp4), each defined by their characteristic genome-wide transcriptomic and DNA methylomic profiles. These subgroups have distinct clinicopathological and molecular features, and underpin current disease subclassification and initial subgroup-directed therapies that are underway in clinical trials. However, substantial biological heterogeneity and differences in survival are apparent within each subgroup, which remain to be resolved. We aimed to investigate whether additional molecular subgroups exist within childhood medulloblastoma and whether these could be used to improve disease subclassification and prognosis predictions. In this retrospective cohort study, we assessed 428 primary medulloblastoma samples collected from UK Children's Cancer and Leukaemia Group (CCLG) treatment centres (UK), collaborating European institutions, and the UKCCSG-SIOP-PNET3 European clinical trial. An independent validation cohort (n=276) of archival tumour samples was also analysed. We analysed samples from patients with childhood medulloblastoma who were aged 0-16 years at diagnosis, and had central review of pathology and comprehensive clinical data. We did comprehensive molecular profiling, including DNA methylation microarray analysis, and did unsupervised class discovery of test and validation cohorts to identify consensus primary molecular subgroups and characterise their clinical and biological significance. We modelled survival of patients aged 3-16 years in patients (n=215) who had craniospinal irradiation and had been treated with a curative intent. Seven robust and reproducible primary molecular subgroups of childhood medulloblastoma were identified. MBWNT remained unchanged and each remaining consensus subgroup was split in two. MBSHH was split into age-dependent subgroups corresponding to infant (<4·3 years; MBSHH-Infant; n=65) and

    Inflammation plays a key role in atherosclerosis and this process seems to appear in childhood. The ideal cardiovascular health index (ICHI) has been inversely related to atherosclerotic plaque in adults. However, evidence regarding inflammation and ICHI in adolescents is scarce. The aim is to assess the association between ICHI and inflammation in European adolescents. As many as 543 adolescents (251 boys and 292 girls) from the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study, a cross-sectional multi-center study including 9 European countries, were measured. C-reactive protein (CRP), complement factors C3 and C4, leptin and white blood cell counts were used to compute an inflammatory score. Multilevel linear models and multilevel logistic regression were used to assess the association between ICHI and inflammation controlling by covariates. Higher ICHI was associated with a lower inflammatory score, as well as with several individual components, both in boys and girls (p < 0.01). In addition, adolescents with at least 4 ideal components of the ICHI had significantly lower inflammatory score and lower levels of the study biomarkers, except CRP. Finally, the multilevel logistic regression showed that for every unit increase in the ICHI, the probability of having an inflammatory profile decreased by 28.1% in girls. Results from this study suggest that a better ICHI is associated with a lower inflammatory profile already in adolescence. Improving these health behaviors, and health factors included in the ICHI, could play an important role in CVD prevention.

    The objective of the NEXT (Nurses' Early Exit) study was to identify the organizational and health factors in the 10 participating countries associated with job satisfaction of nurses and nurses' aides or with their desire to change occupation or stop working prematurely. Questions about health were somewhat more detailed in the French version of the questionnaire and allowed us to determine health behaviors of this representative sample of French caregivers (PRESST: Promotion of Health and Job Satisfaction of European Healthcare Workers [www.next-study.net; www.presst-next.fr]). Of the 6980 (796 men and 6184 women) nurses and nurses' aides studied in late 2002 and early 2003, 32.6% reported that they smoked at least occasionally and 24.3% regularly. Only 24.4% of the staff in our sample exercised at least weekly. Overweight was observed in 27,6% of the sample, mostly women (42% of men and 24.7% of women), and obesity affected 6,4% of men and 7% of women. Overweight was slightly less frequent than among the general adult population of France, 39.8% according to the CREDES SPS survey in 2002, but these healthcare workers were younger. On the whole, burnout was higher among French caregivers than among those from other European nations in the Next study. This study demonstrates the need to conduct and assess interventions for the dual purpose of (1) reducing the morbidity and mortality associated with the conditions most sensitive to these risk factors in healthcare personnel and (2) improving their knowledge, motivations and credibility in providing health education to patients.

  6. Toward Computational Spectroscopy Studies for Large Molecular Systems

    Integrated computational approaches built on quantum mechanical (QM) methods combined with time-independent schemes to account for nuclear motion effects are applied to the spectroscopic investigation of molecular systems, from large biomolecules to hybrid supra-molecular systems. Within the time-independent approaches, vibrational spectra are computed including anharmonicities through perturbative corrections while UV-vis line-shapes are simulated accounting for the vibrational structure; in both cases, the environmental effects are taken into account by explicit or continuum models. Extension to larger systems relies on reduced dimensionality approaches and effective schemes to select transitions of interest, available for both vibrational and vibronic spectra. Such procedures are exploited to simulate IR and UV-vis spectra leading in all cases to good agreement with experimental observations and allowing to dissect different effects underlying spectral phenomena, finally, paving a feasible route toward the state-of-the-art computational spectroscopy studies, even for relatively large molecular systems [1,2]. 1.

    A systematic vibrational spectroscopic assignment and analysis of piracetam [(2-oxo-1-pyrrolidineacetamide)] have been carried out using FT-IR and FT-Raman spectral data. The vibrational analysis was aided by an electronic structure calculation based on the hybrid density functional method B3LYP using a 6-311G++(d,p) basis set. Molecular equilibrium geometries, electronic energies, IR and Raman intensities, and harmonic vibrational frequencies have been computed. The assignments are based on the experimental IR and Raman spectra, and a complete assignment of the observed spectra has been proposed. The UV-visible spectrum of the compound was recorded and the electronic properties, such as HOMO and LUMO energies and the maximum absorption wavelengths λmax were determined by the time-dependent DFT (TD-DFT) method. The geometrical parameters, vibrational frequencies and absorption wavelengths were compared with the experimental data. The complete vibrational assignments are performed on the basis of the potential energy distributions (PED) of the vibrational modes in terms of natural internal coordinates. The simulated FT-IR, FT-Raman, and UV spectra of the title compound have been constructed. Molecular docking studies have been carried out in the active site of piracetam by using Argus Lab. In addition, the potential energy surface, HOMO and LUMO energies, first-order hyperpolarizability and the molecular electrostatic potential have been computed. Copyright © 2014 Elsevier B.V.

  8. Need for a European approach to the effects of extremely low-frequency electromagnetic fields on cancer. ELF-EMF European Feasibility Study Group.

    Science.gov (United States)

    1997-02-01

    A European feasibility study on environmental exposure to extremely low-frequency electromagnetic fields (ELF-EMF) and cancer was conducted. The study was motivated by public health concern about possible adverse health effects associated with ELF-EMF exposure. A review of completed research in Europe was conducted. Information on the methods and accessibility of new epidemiologic studies were requested and reviewed. Eight studies on environmental ELF-EMF exposure have been completed in Europe while 15 large studies are in progress. Although there is no known mechanism by which electric or magnetic fields of this frequency could play a role in the development of cancer or other adverse health effects, the results of the studies conducted so far provide some support for the hypothesis that they are associated with the incidence of childhood leukemia. The best use of available data will be made through a pooled re-analysis of data, particularly those on childhood tumors. It is recommended to apply multiple methods for exposure assessment in view of the heterogeneity in the methods used in different studies. New multicenter case-referent studies should not be initiated until the results of the large on-going studies have been reported. Prospective cohort studies will have to be very large to identify moderate excess risks resulting from environmental exposure to ELF-EMF, and their feasibility should be discussed after the results of the on-going case-referent studies have been reported. A European collaborative approach will lead to greater statistical power and will assess the exposure-effect association under differing exposure patterns and distributions of potential confounding factors.

    ABSTRACT Rotavirus (RV) is worldwide considered as the most important viral agent of acute gastroenteritis in children less than 5 y. Since 2006, the availability of anti-RV vaccines has deeply modified the incidence and economic burden of RV infection. In Europe, some countries have introduced an anti-RV vaccination program in the last 10 y. Although community acquired RV (CARV) disease is the most studied condition of RV infection, recently some authors have highlighted the importance of nosocomial RV (nRV) disease as an emerging public health issue. The aim of this review is to summarize the epidemiology of both CARV and nRV, in order to discuss the difficulty of a clear evaluation of the burden of the disease in absence of comparable data. In particular, we focused our attention to European studies regarding nRV in terms of divergences related to definition, report of incidence rate and methodological issues. PMID:27185183

    The goal of this European pilot study was to evaluate the knowledge, attitudes and beliefs of prison staff from five countries towards HIV infection and to identify factors related to the potential discrimination of HIV-positive inmates. The survey revealed that the levels of knowledge with regard to HIV transmission and the degrees of tolerance varied significantly between prisons. A large proportion of staff overestimated the prevalence of HIV in their prison and feared being contaminated. The willingness of the staff to know the inmates' HIV seropositive status was negatively correlated to their level of tolerance; however, it was positively correlated to their knowledge of the modes of HIV transmission. This study underlines the necessity to improve HIV/AIDS prevention policy for prison staff in order to strengthen good practice in terms of managing the risk of contamination and hindering discrimination.

    Full Text Available Background Cervical cancer is the fourth most common cancer affecting women worldwide. Since 2006, two Human Papillomavirus vaccines (HPVV have been licensed to protect women against the virus that causes cervical cancer. However, worldwide coverage remains unequal. Studies from the USA found strong evidence for differences in HPVV uptake by ethnicity and healthcare coverage. As the profile of ethnic groups and the healthcare system in the USA differ from countries in Europe where HPVV is free in most of the countries, we conducted a systematic review in order to analyze the determinants of HPVV uptake in Europe.Methods We performed a systematic Pubmed, Scopus and Science Direct search to find articles published from HPVV availability in European countries until April 2014. No age restriction was applied. We included all studies assessing factors associated with HPVV uptake. Uptake refers to either initiation and/or completion of the three dose vaccination program. Results Out of the 23 eligible studies, 14 were retrospective reviews of data, six were cross-sectional surveys and three were prospective cohort studies. Higher HPVV uptake was associated with ethnic majority populations, higher socio-economic status, regular cervical screening participation by the mother and having received previous childhood vaccinations.Conclusions Since the vaccine is offered for free in most of the European countries, the findings suggest that ethno-cultural and educational factors play an important role when it comes to HPVV uptake. Girls who were undervaccinated had also a lower uptake of standard childhood vaccines and mothers who were less likely to attend cervical cancer screening. This may indicate, that only few parents have specific concerns with HPVV, and that preventive health care should seek ways to target these vulnerable groups.

    2010-09-01

    Full Text Available Abstract Background The identification of vast numbers of unknown organisms using DNA sequences becomes more and more important in ecological and biodiversity studies. In this context, a fragment of the mitochondrial cytochrome c oxidase I (COI gene has been proposed as standard DNA barcoding marker for the identification of organisms. Limitations of the COI barcoding approach can arise from its single-locus identification system, the effect of introgression events, incomplete lineage sorting, numts, heteroplasmy and maternal inheritance of intracellular endosymbionts. Consequently, the analysis of a supplementary nuclear marker system could be advantageous. Results We tested the effectiveness of the COI barcoding region and of three nuclear ribosomal expansion segments in discriminating ground beetles of Central Europe, a diverse and well-studied invertebrate taxon. As nuclear markers we determined the 18S rDNA: V4, 18S rDNA: V7 and 28S rDNA: D3 expansion segments for 344 specimens of 75 species. Seventy-three species (97% of the analysed species could be accurately identified using COI, while the combined approach of all three nuclear markers provided resolution among 71 (95% of the studied Carabidae. Conclusion Our results confirm that the analysed nuclear ribosomal expansion segments in combination constitute a valuable and efficient supplement for classical DNA barcoding to avoid potential pitfalls when only mitochondrial data are being used. We also demonstrate the high potential of COI barcodes for the identification of even closely related carabid species.

    Full Text Available Background: Compared with European Americans, African Americans (AA exhibit lower levels of the cardio-metabolically protective adiponectin even after accounting for adiposity measures. Because few studies have examined in AA the association between adiponectin and genetic admixture, a dense panel of ancestry informative markers (AIMs was used to estimate the individual proportions of European ancestry (PEA for the African Americans enrolled in a large community-based cohort, the Jackson Heart Study (JHS. We tested the hypothesis that plasma adiponectin and PEA are directly associated and assessed the interaction with a series of cardio-metabolic risk factors.Methods: Plasma specimens from 1,439 JHS participants were analyzed by ELISA for adiponectin levels. Using pseudo-ancestral population genotype data from the HapMap Consortium, PEA was estimated with a panel of up to 1,447 genome-wide preselected AIMs by a maximum likelihood approach. Interaction assessment, stepwise linear and cubic multivariable-adjusted regression models were used to analyze the cross-sectional association between adiponectin and PEA.Results: Among the study participants (62% women; mean age 48 ± 12 years, the median (interquartile range of PEA was 15.8 (9.3%. Body mass index (p = 0.04 and insulin resistance (p = 0.0001 modified the association between adiponectin and PEA. Adiponectin was directly and linearly associated with PEA (β = 0.62 ± 0.28, p = 0.03 among non-obese (n = 673 and insulin sensitive participants (n = 1,141; β = 0.74 ± 0.23, p = 0.001, but not among those obese or with insulin resistance. No threshold effect was detected for non-obese participants.Conclusions: In a large African American population, the individual proportion of European ancestry was linearly and directly associated with plasma adiponectin among non-obese and non insulin-resistant participants, pointing to the interaction of genetic and metabolic factors influencing adiponectin

  16. Molecular determinants of epidermal growth factor binding: a molecular dynamics study.

    Directory of Open Access Journals (Sweden)

    Jeffrey M Sanders

    Full Text Available The epidermal growth factor receptor (EGFR is a member of the receptor tyrosine kinase family that plays a role in multiple cellular processes. Activation of EGFR requires binding of a ligand on the extracellular domain to promote conformational changes leading to dimerization and transphosphorylation of intracellular kinase domains. Seven ligands are known to bind EGFR with affinities ranging from sub-nanomolar to near micromolar dissociation constants. In the case of EGFR, distinct conformational states assumed upon binding a ligand is thought to be a determining factor in activation of a downstream signaling network. Previous biochemical studies suggest the existence of both low affinity and high affinity EGFR ligands. While these studies have identified functional effects of ligand binding, high-resolution structural data are lacking. To gain a better understanding of the molecular basis of EGFR binding affinities, we docked each EGFR ligand to the putative active state extracellular domain dimer and 25.0 ns molecular dynamics simulations were performed. MM-PBSA/GBSA are efficient computational approaches to approximate free energies of protein-protein interactions and decompose the free energy at the amino acid level. We applied these methods to the last 6.0 ns of each ligand-receptor simulation. MM-PBSA calculations were able to successfully rank all seven of the EGFR ligands based on the two affinity classes: EGF>HB-EGF>TGF-α>BTC>EPR>EPG>AR. Results from energy decomposition identified several interactions that are common among binding ligands. These findings reveal that while several residues are conserved among the EGFR ligand family, no single set of residues determines the affinity class. Instead we found heterogeneous sets of interactions that were driven primarily by electrostatic and Van der Waals forces. These results not only illustrate the complexity of EGFR dynamics but also pave the way for structure-based design of

    Full Text Available Abstract Background A number of single nucleotide polymorphisms (SNPs have been associated with broadband ultrasound attenuation (BUA and speed of sound (SOS as measured by quantitative ultrasound (QUS at the calcaneus in the Framingham 100K genome-wide association study (GWAS but have not been validated in independent studies. The aim of this analysis was to determine if these SNPs are associated with QUS measurements assessed in a large independent population of European middle-aged and elderly men. The association between these SNPs and bone mineral density (BMD measured using dual-energy X-ray absorptiometry (DXA was also tested. Methods Men aged 40-79 years (N = 2960 were recruited from population registers in seven European centres for participation in an observational study of male ageing, the European Male Ageing Study (EMAS. QUS at the calcaneus was measured in all subjects and blood was taken for genetic analysis. Lumbar spine (LS, femoral neck (FN and total hip (TH BMD were measured by DXA in a subsample of 620 men in two centres. SNPs associated with BUA or SOS in the Framingham study with p -4 were selected and genotyped using SEQUENOM technology. Linear regression was used to test for the association between SNPs and standardised (SD bone outcomes under an additive genetic model adjusting for centre. The same direction of effect and p Results Thirty-four of 38 selected SNPs were successfully genotyped in 2377 men. Suggestive evidence of replication was observed for a single SNP, rs3754032, which was associated with a higher SOS (β(SD = 0.07, p = 0.032 but not BUA (β(SD = 0.02, p = 0.505 and is located in the 3'UTR of WDR77 (WD repeat domain 77 also known as androgen receptor cofactor p44.

German preschoolers spent the least amount of time in television viewing (43.3 min/day on weekdays, while Greek preschoolers spent the most time in television viewing (88.5 min/day on weekdays. A considerable amount of time was spent in quiet play in all countries, with the highest levels in Poland (104.9 min/day on weekdays, and the lowest levels in Spain (60.4 min/day on weekdays. Belgian, German, and Polish preschoolers had the lowest intakes of water and the highest intakes of sugar-sweetened beverages. The intake of snacks was the highest in Belgian preschoolers (73.1 g/day and the lowest in Greek preschoolers (53.3 g/day.Across six European countries, differences in preschoolers' energy balance-related behaviours were found. Future interventions should target European preschoolers' energy balance-related behaviours simultaneously, but should

    Full Text Available Anxiety disorders (ADs are common mental disorders caused by a combination of genetic and environmental factors. Since ADs are highly comorbid with each other, partially due to shared genetic basis, studying AD phenotypes in a coordinated manner may be a powerful strategy for identifying potential genetic loci for ADs. To detect these loci, we performed genome-wide association studies (GWAS of ADs. In addition, as a complementary approach to single-locus analysis, we also conducted gene- and pathway-based analyses. GWAS data were derived from the control sample of the Molecular Genetics of Schizophrenia (MGS project (2,540 European American and 849 African American subjects genotyped on the Affymetrix GeneChip 6.0 array. We applied two phenotypic approaches: (1 categorical case-control comparisons (CC based upon psychiatric diagnoses, and (2 quantitative phenotypic factor scores (FS derived from a multivariate analysis combining information across the clinical phenotypes. Linear and logistic models were used to analyse the association with ADs using FS and CC traits, respectively. At the single locus level, no genome-wide significant association was found. A trans-population gene-based meta-analysis across both ethnic subsamples using FS identified three genes (MFAP3L on 4q32.3, NDUFAB1 and PALB2 on 16p12 with genome-wide significance (false discovery rate (FDR] <5%. At the pathway level, several terms such as transcription regulation, cytokine binding, and developmental process were significantly enriched in ADs (FDR <5%. Our approaches studying ADs as quantitative traits and utilizing the full GWAS data may be useful in identifying susceptibility genes and pathways for ADs.

    The combination of therapy and diagnostics in one process "theranostics" is a trend in a modern medicine, especially in oncology. Such an approach requires development and usage of multifunctional hybrid nanoparticles with a hierarchical structure. Numerical methods and mathematical models play a significant role in the design of the hierarchical nanoparticles and allow looking inside the nanoscale mechanisms of agent-cell interactions. The current position of in silico approach in biomedicine and oncology is discussed. The review of the molecular level in silico studies in oncology, which are using the direct models, is presented.

    Nosema ceranae, a microsporidian parasite originally described from Apis cerana, has been found to infect Apis melllifera and is highly pathogenic to its new host. In the present study, data on the ultrastructure of N. ceranae, presence of N. ceranae-specific nucleic acid in host tissues, and phylogenetic relationships with other microsporidia species are described. The ultrastructural features indicate that N. ceranae possesses all of the characteristics of the genus Nosema. Spores of N. ceranae measured approximately 4.4 × 2.2 μm on fresh smears. The number of coils of the polar filament inside spores was 18--21. PCR signals specific for N. ceranae were detected not only in the primary infection site, the midgut, but also in the tissues of hypopharyngeal glands, salivary glands, Malpighian tubules, and fat body. The detection rate and intensity of PCR signals in the fat body were relatively low compared to other examined tissues. Maximum parsimony analysis of the small subunit rRNA gene sequences showed that N. ceranae appeared to be more closely related to the wasp parasite, N. vespula than to N. apis, a parasite infecting the same host.

    The magnitude of socioeconomic inequalities in mortality differs importantly between countries, but these variations have not been satisfactorily explained. We explored the role of behavioral and structural determinants of these variations, by using a dataset covering 17 European countries in the period 1970-2010, and by conducting multilevel multivariate regression analyses. Our results suggest that between-country variations in inequalities in current mortality can partly be understood from variations in inequalities in smoking, excessive alcohol consumption, and poverty. Also, countries with higher national income, higher quality of government, higher social transfers, higher health care expenditure and more self-expression values have smaller inequalities in mortality. Finally, trends in behavioral risk factors, particularly smoking and excessive alcohol consumption, appear to partly explain variations in inequalities in mortality trends. This study shows that analyses of variations in health inequalities between countries can help to identify entry-points for policy. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    Hospitals are making big investments in various types of ICT, so it is important to investigate their effects on innovation and performance. This paper presents an empirical study in this direction, based on data for 743 hospitals from 18 European countries. We specified and estimated econometrically five equations: one for product innovation, one for process innovation and three equations for the three different dimensions of (ICT-enabled) hospital performance. All five equations included various ICT-related variables reflecting ICT infrastructure and a series of important ICT applications, some of them hospital-specific, and some others of general business use, and also ICT personnel (viewed as a kind of 'soft' ICT investment), while the performance equations also included the two innovation measures.

  5. VSI@ESS: Case study for a vibrational spectroscopy instrument at the european spallation source

    2015-01-01

    Full Text Available Neutron Vibrational Spectroscopy is a well-established experimental technique where elementary excitations at relatively high frequency are detected via inelastic neutron scattering. This technique attracts a high interest in a large fraction of the scientific community in the fields of chemistry, materials science, physics, and biology, since one of its main applications exploits the large incoherent scattering cross section of the proton with respect to all the other elements, whose dynamics can be spectroscopically detected, even if dissolved in very low concentration in materials composed of much heavier atoms. We have proposed a feasibility study for a Vibrational Spectroscopy Instrument (VSI at the European Spallation Source ESS. Here, we will summarize the preliminary design calculations and the corresponding McStas simulation results for a possible ToF, Inverted Geometry, VSI beamline.

    Full Text Available Diffuse and bi-directional reflectance spectroscopy were applied in this research in order to characterize chemical and mineralogical properties in volcanic soils. The study was conducted on 77 volcanic soil profiles from several European countries. Diffuse reflectance spectroscopy was used in conjunction with parameterization using the second derivative of the Kubelka-Munk function and colour calculation. From derivative curves, one band of interest was characterized and identified around 450 nm. Using correlation analysis, significant relationships were observed between amplitude of this band and Fed (r = 0.6. In addition, the data showed that soil organic matter content, Ald and Fep were moderately correlated with reflectance values centered at 546, 579 and 2048 nm.

    Since stress is hypothesized to be involved in the aetiology of obesity, the present study examined the current perception of stress in European adolescents and the association between adolescent perceived stress and their adiposity. Observational data from 1121 adolescents aged 12.5-17.5 years from six European cities involved in the Healthy Lifestyle in Europe by Nutrition in Adolescence cross-sectional study, was investigated. The adolescents completed the adolescent stress questionnaire, comprising 10 different stress dimensions. Anthropometric measurements (weight, height, skinfold thicknesses and circumferences) and bioelectrical impedance analysis were performed, and personal characteristics (age, pubertal stage and parental education) were collected. The measures of perceived stress were described for boys and girls separately and gender differences were investigated. Associations between the adolescents' perceived stress and indicators of general (body mass index z-score, sum of skinfold thicknesses and body fat%) and abdominal (waist and hip circumference, and waist/height ratio) adiposity were examined using hierarchical linear models. While girls reported systematically higher levels of stress compared with boys, their stress profiles were similar, with highest levels for school-related stress followed by future uncertainty. Only in girls, perceived stress was significantly associated with increased measures of general and abdominal adiposity. In boys, no relationship between perceived stress and adiposity measures was observed. School is reported to be an important source of adolescent stress and should be the focus of stress management campaigns. Only in girls, the hypothesis that stress might be involved in the aetiology of obesity during adolescence was supported.

    Because of the magnitude of the global tobacco epidemic, the World Health Organisation developed the Framework Convention on Tobacco Control (FCTC), an international legally binding treaty to control tobacco use. Adoption and implementation of specific tobacco control measures within FCTC is an outcome of a political process, where social norms and public opinion play important roles. The objective of our study was to examine how a country's level of tobacco control is associated with smoking prevalence, two markers of denormalisation of smoking (social disapproval of smoking and concern about passive smoking), and societal support for tobacco control. An ecological study was conducted, using data from two sources. The first source was the Tobacco Control Scale (TCS) from 2011, which quantifies the implementation of tobacco control policies in European Union (EU) countries. Data on smoking prevalence, societal disapproval of smoking, concern about passive smoking, and societal support for policy measures were taken from the Eurobarometer survey of 2009. Data from Eurobarometer surveys were aggregated to country level. Data from the 27 European Union member states were used. Smoking prevalence rates in 2009 were negatively associated with a country's TCS 2011 score, although not statistically significant (r = -.25; p = .21). Experience of societal disapproval was positively associated with higher TCS scores, though not significantly (r = .14; p = .48). The same was true for societal support for tobacco control (r = .27; p = .18). The TCS score in 2011 was significantly correlated with concern about passive smoking (r = .42; p =.03). Support for tobacco control measures was also strongly correlated with concern about passive smoking (r = .52, p = .006). Smokers in countries with a higher TCS score were more concerned about whether their smoke harms others. Further, support for tobacco control measures is higher in countries that have more of these concerned smokers

    The assessment of individual vulnerability to stress emerges as a predictive factor of a higher risk of developing stress-related disorders. In the last decade, the geography of immigration in Portugal experienced intense transformations in terms of recruitment and patterns of geographic settlement, with an increasing and exponential inflow of new and diversified migratory groups. The immigrant populations coming from Eastern European countries are a recent migratory flow, with linguistic, cultural and socio-demographic specificities which are very different from the general Portuguese population. This makes them a paradigmatic group in potential transcultural studies on mental health issues. The primary aim of the study was to describe the characteristics of vulnerability to stress and determine their impact on the mental health status of Russian-speaking immigrants residing in Portugal. The relationship between vulnerability to stress, sociodemographic variables, mental health status and social support were analyzed, using the SSQ6, GHQ28, 23QVS and a socio-demographic questionnaire. A comparative analysis was carried out, using a control group of 110 Portuguese subjects without previous migratory experiences, matched by sex, age group and academic qualifications. The eastern European immigrants reported high levels of vulnerability to stress assessed by the cut-off point of the 23QVS. Immigrants also reported higher percentage of vulnerability to stress and lower social support levels of social support versus the control group. Several factors inherent to the dynamics of the migratory process were related to the presence of vulnerability to stress. The findings suggest that vulnerability to stress is positively correlated with worse mental health outcomes and negatively correlated with the social support perceived as available--number of supporters and satisfaction with social support.

    Full Text Available The objective was to identify the main factors influencing micronutrient policies in the opinion of policy actors in ten European countries. Study was carried out during Jan-Nov 2010 in European countries: the Czech Republic, Denmark, England, Germany, Greece, Italy, the Netherlands, Norway, Poland and Spain. Semi-structured qualitative interviews were conducted with representatives of stakeholders involved in the vitamin D, folate and iodine policy making process. Fifty eight key informants representing mainly scientific advisory bodies (n=24 and governmental organisations (n=19 participated in the study. The remaining interviewees represented non-governmental organisations (n=6, industry (n=4 or were independent academic or health professional experts (n=5. Data were analysed by theoretical interpretative thematic analysis. Insights from interviewees on the development of micronutrient policies were grouped using the Public Health Nutrition Policy-making model. The main factors influencing the micronutrient policies were: systematic monitoring of nutrition and health, causal relationships between consumers’ diet-related behaviours and health outcomes, scientific recommendations from national bodies (Science area; scientific recommendations from international authorities and experiences of other countries, EU legislation, cultural factors (Wider context and political environment, national capacity to deal with the problem, national legislation, economics, stakeholder engagement, relationships between stakeholders (Policy and institutions area. The spectrum and weight of the factors influencing nutritional policy depends on nutrient, country and degree of its “advanced status” within nutrition policy, political environment, culture and socio-economic conditions as well as the point of view (who is expressing the opinion.

    Injury to children in Europe, resulting in both death and disability, constitutes a significant burden on individuals, families and society. Inequalities between high and low-income countries are growing. The World Health Organisation Health 2020 strategy calls for inter-sectoral collaboration to address injury in Europe and advocates the whole of government and whole of society approaches to wicked problems. In this study we explore which sectors (e.g. health, transport, education) are relevant for four domains of child safety (intentional injury, water, road and home safety). We used the organigraph methodology, originally developed to demonstrate how organizations work, to describe the governance of child safety interventions. Members of the European Child Safety Alliance, working in the field of child safety in 24 European countries, drew organigraphs of evidence-based interventions. They included the different actors involved and the processes between them. We analyzed the organigraphs by counting the actors presented and categorizing them into sectors using a pre-defined analysis framework. We received 44 organigraphs from participants in 24 countries. Twenty-seven sectors were identified across the four domains. Nine of the 27 identified sectors were classified as 'core sectors' (education, health, home affairs, justice, media, recreation, research, social/welfare services and consumers). This study reveals the multi-sectoral nature of child safety in practice. It provides information for stakeholders working in child safety to help them implement inter-sectoral child safety interventions taking a whole-of-government and whole-of-society approach to health governance.

    2017-04-26

    In 1974, molecular electronics pioneers Mark Ratner and Arieh Aviram predicted that a single molecule could act as a diode, in which electronic current can be rectified. The electronic rectification property of the diode is one of basic functions of electronic components and since then, the molecular diode has been investigated as a first single-molecule device that would have a practical application. In this review, we first describe the experimental fabrication and electronic characterization techniques of molecular diodes consisting of a small number of molecules or a single molecule. Then, two main mechanisms of the rectification property of the molecular diode are discussed. Finally, representative results for the molecular diode are reviewed and a brief outlook on crucial issues that need to be addressed in future research is discussed.

    2013-11-01

    The concept of single crystals of macromolecules as thermodynamic systems is not a common one. However, it should be possible to derive thermodynamic properties from single crystal structures, if the process of crystallization follows thermodynamic rules. We review here an example of how the stabilizing potentials of molecular interactions can be measured from studying the properties of DNA crystals. In this example, we describe an assay based on the four-stranded DNA junction to determine the stabilizing potentials of halogen bonds, a class of electrostatic interactions, analogous to hydrogen bonds, that are becoming increasing recognized as important for conferring specificity in protein-ligand complexes. The system demonstrates how crystallographic studies, when coupled with calorimetric methods, allow the geometries at the atomic level to be directly correlated with the stabilizing energies of molecular interactions. The approach can be generally applied to study the effects of DNA sequence and modifications of the thermodynamic stability of the Holliday junction and, by inference, on recombination and recombination dependent processes.

    The successful advent of a genome-wide approach in association studies raises the hopes of human geneticists for solving a genetic maze of complex traits especially the disorders. This approach, which is replete with the application of cutting-edge technology and supported by big science projects (like Human Genome Project; and even more importantly the International HapMap Project) and various important databases (SNP database, CNV database, etc.), has had unprecedented success in rapidly uncovering many of the genetic determinants of complex disorders. The magnitude of this approach in the genetics of classical anthropological variables like height, skin color, eye color, and other genome diversity projects has certainly expanded the horizons of molecular anthropology. Therefore, in this article we have proposed a genome-wide association approach in molecular anthropological studies by providing lessons from the exemplary study of the Wellcome Trust Case Control Consortium. We have also highlighted the importance and uniqueness of Indian population groups in facilitating the design and finding optimum solutions for other genome-wide association-related challenges.

    Obese individuals are more likely to develop heart failure. Yet, once heart failure is established, the impact of overweight and obesity on prognosis and survival is unclear. The purpose of this joint scientific statement of the European Association for the Study of Obesity and the European Society of Hypertension is to provide an overview on the current scientific literature on obesity and heart failure in terms of prognosis, mechanisms, and clinical management implications. Moreover, the document identifies open questions that ought to be addressed. The need for more tailored weight management recommendations in heart failure will be emphasized and, in line with the emerging evidence, aims to distinguish between primary disease and secondary outcome prevention. In the primary prevention of heart failure, it appears prudent advising obese individuals to lose or achieve a healthy body weight, especially in those with risk factors such as hypertension or type 2 diabetes. However, there is no evidence from clinical trials to guide weight management in overweight or obese patients with established heart failure. Prospective clinical trials are strongly encouraged.

    The development of structured and validated training curricula is one of the current priorities in robot-assisted urological surgery. To establish the feasibility, acceptability, face validity, and educational impact of a structured training curriculum for robot-assisted radical prostatectomy (RARP), and to assess improvements in performance and ability to perform RARP after completion of the curriculum. A 12-wk training curriculum was developed based on an expert panel discussion and used to train ten fellows from major European teaching institutions. The curriculum included: (1) e-learning, (2) 1 wk of structured simulation-based training (virtual reality synthetic, animal, and cadaveric platforms), and (3) supervised modular training for RARP. The feasibility, acceptability, face validity, and educational impact were assessed using quantitative surveys. Improvement in the technical skills of participants over the training period was evaluated using the inbuilt validated assessment metrics on the da Vinci surgical simulator (dVSS). A final RARP performed by fellows on completion of their training was assessed using the Global Evaluative Assessment of Robotic Skills (GEARS) score and generic and procedure-specific scoring criteria. The median baseline experience of participants as console surgeon was 4 mo (interquartile range [IQR] 0-6.5 mo). All participants completed the curriculum and were involved in a median of 18 RARPs (IQR 14-36) during modular training. The overall score for dVSS tasks significantly increased over the training period (p10 (scale 4-16) for all procedural steps using a generic dedicated scoring tool. In performance comparison using this scoring tool, the experts significantly outperformed the fellows (mean score for all steps 13.6 vs 11). The European robot-assisted urologic training curriculum is acceptable, valid, and effective for training in RARP. This study shows that a 12-wk structured training program including simulation

    2015-04-01

    A measurement system for location seismic events in the Central Part of East European Platform is situated within the Mikhnevo Geophysical Observatory of the RAS Institute of Geospheres Dynamics and consists of 12 seismic stations. One vertical station is located in the center of the group in a shaft tunnel. The other stations are located on the periphery in three concentric circles and are almost equally spaced with regard to the terrain to ensure full azimuth coverage to the maximum extent possible. The unique array identifies events with a magnitude up to 3 at the distances until 1000 km within the Central Part of East European platform. Most of the events recorded by the Mikhnevo array at a distance of 60-500 km are man-made events represented by explosions in quarries during the development of mineral deposits. Long-term seismic records of explosions in quarries have been processed for the period from 2004 to 2014 to generate a database containing standard waveforms for each quarry. Some events of unknown origin appear in the records for this period; these do not correspond to the identified seismic forms for explosions in known quarries. Epicenter coordinates for these events do not match the coordinates of the known quarries. A cosmotectonic map of the Central Part of East European Platform was compiled during the studies using the LESSA software package (Lineament Extraction and Stripe Statistical Analysis) and data on the deep crustal structure, which made it possible to define the morphostructural plan and evaluate the geodynamic conditions in the area. The deep basement structure through the sedimentary cover is expressed in the surface texture of the area under study. The region's neotectonics is closely related to the history of deep structures, in particular, aulacogens extending in different directions, which may show in the contemporary morphostructural plan, mainly as inversion and partially inherited forms.

    The aim of this study was to examine the psychometric properties of the European Portuguese version of the World Health Organization Quality of Life-Older Adults Module (WHOQOL-OLD). The European Portuguese WHOQOL-OLD includes a new identified facet, Family/Family life. A convenience sample of older adults was recruited (N = 921). The assessment protocol included demographics, self-perceived health, depressive symptoms (GDS-30), cognitive function (ACE-R), daily life activities (IAFAI), health status (SF-12) and QoL (WHOQOL-Bref, EUROHIS-QOL-8 and WHOQOL-OLD). The internal consistency was excellent for the total 24-item WHOQOL-OLD original version and also for the final 28-item European Portuguese WHOQOL-OLD version. The test-retest reliability for total scores was good. The construct validity of the European Portuguese WHOQOL-OLD was supported in the correlation matrix analysis. The results indicated good convergent/divergent validity. The WHOQOL-OLD scores differentiated groups of older adults who were healthy/unhealthy and without/mild/severe depressive symptoms. The new facet, Family/Family life, presented evidence of good reliability and validity parameters. Comparatively to international studies, the European Portuguese WHOQOL-OLD version showed similar and/or better psychometric properties. The new facet, Family/Family life, introduces cross-cultural specificity to the study of QoL of older adults and generally improves the psychometric robustness of the WHOQOL-OLD.

The level of genetic diversity was assessed in Alburnus alburnus, Alburnoides bipunctatus, C. genei, C. n. nasus, C. soetta, C. t. toxostoma, L. idus, L. leuciscus, Pachychilon pictum, Rutilus rutilus, Squalius cephalus and Telestes souffia. The applicability of the markers was also tested on Abramis brama, Blicca bjoerkna and Scardinius erythrophtalmus specimens. Overall, between 24 and 37 of these markers revealed polymorphic for the investigated species and 23 markers amplified for all the 15 European cyprinid species. Conclusions The developed set of markers demonstrated its performance in discriminating European cyprinid species. Furthermore, it allowed detecting and characterizing hybrid individuals. These microsatellites will therefore be useful to perform comparative evolutionary and population genetics studies dealing with European cyprinids, what is of particular interest in conservation issues and constitutes a tool of choice to conduct hybridization studies.

    Full Text Available Hydrotropy is a phenomenon where the presence of a large quantity of one solute enhances the solubility of another solute. The mechanism of this phenomenon remains a topic of debate. This study employed molecular dynamics simulation to investigate the hydrotropic mechanism of a series of urea derivatives, that is, urea (UR, methylurea (MU, ethylurea (EU, and butylurea (BU. A poorly water-soluble compound, nifedipine (NF, was used as the model solute that was solubilized. Structural, dynamic, and energetic changes upon equilibration were analyzed to supply insights to the solubilization mechanism. The study demonstrated that NF and urea derivatives underwent significant nonstoichiometric molecular aggregation in the aqueous solution, a result consistent with the self-aggregation of urea derivatives under the same conditions. The analysis of hydrogen bonding and energy changes revealed that the aggregation was driven by the partial restoration of normal water structure. The energetic data also suggested that the promoted solubilization of NF is favored in the presence of urea derivatives. While the solutes aggregated to a varying degree, the systems were still in single-phase liquid state as attested by their active dynamics.

    Head injuries are considered harmful in children. We analyzed head and neck injuries in organized football in 7- to 12-year-old children. Data for this analysis were obtained from a prospective cohort study over two consecutive football seasons in two European countries, and a randomized intervention trial over one season in four European countries. Football exposure and injuries were documented through an online database. Detailed information regarding injury characteristics and medical follow-up was retrieved from coaches, children and parents by phone. Thirty-nine head injuries and one neck injury (5% of all 791 injuries) were documented during 9933 player-seasons (total football exposure 688 045 hours). The incidence was 0.25 [95%CI 0.15, 0.35] head/neck injuries per 1000 match hours (N=23 match injuries) and 0.03 [95%CI 0.02, 0.03] per 1000 training hours. Eleven concussions (27.5%), nine head contusions (22.5%), eight lacerations or abrasions (20%), two nose fractures (2.5%), and two dental injuries (2.5%) occurred. The remaining eight injuries were nose bleeding or other minor injuries. Thirty injuries (75%) resulted from contact with another player, and ten injuries were due to collision with an object, falling or a hit by the ball. Whereas 70% of all head injuries (N=28) were due to frontal impacts, 73% of concussions (N=8) resulted from an impact to the occiput. The incidence and severity of head injuries in children's football are low. Coaches and parents, however, should be sensitized regarding the potential of concussions, particularly after an impact to the occiput. © 2017 John Wiley & Sons A/S.

    Indoor environmental conditions (thermal, noise, light, and indoor air quality) may affect workers' comfort, and consequently their health and well-being, as well as their productivity. This study aimed to assess the relations between perceived indoor environment and occupants' comfort, and to examine the modifying effects of both personal and building characteristics. Within the framework of the European project OFFICAIR, a questionnaire survey was administered to 7441 workers in 167 "modern" office buildings in eight European countries (Finland, France, Greece, Hungary, Italy, The Netherlands, Portugal, and Spain). Occupants assessed indoor environmental quality (IEQ) using both crude IEQ items (satisfaction with thermal comfort, noise, light, and indoor air quality), and detailed items related to indoor environmental parameters (e.g., too hot/cold temperature, humid/dry air, noise inside/outside, natural/artificial light, odor) of their office environment. Ordinal logistic regression analyses were performed to assess the relations between perceived IEQ and occupants' comfort. The highest association with occupants' overall comfort was found for "noise", followed by "air quality", "light" and "thermal" satisfaction. Analysis of detailed parameters revealed that "noise inside the buildings" was highly associated with occupants' overall comfort. "Layout of the offices" was the next parameter highly associated with overall comfort. The relations between IEQ and comfort differed by personal characteristics (gender, age, and the Effort Reward Imbalance index), and building characteristics (office type and building's location). Workplace design should take into account both occupant and the building characteristics in order to provide healthier and more comfortable conditions to their occupants.

    In the European context regulated by the Bologna Process principles, there is little evidence to date on the different profiles, if any, of nursing students enrolled in the 1st academic year and their academic outcomes. To describe and compare the nursing student profiles and their academic outcomes at the end of the 1st year across European Bachelor of Nursing Science (BNS) courses. An exploratory multicentre cohort study involving five countries: Nursing students who were enrolled in nursing programmes for the academic year 2011/2012 in the participating BNS courses, willing to participate and regularly admitted to the 2nd academic year, were included in this study undertaken in 2013. Individual and faculty level variables were collected after having ensured the validity of the tools developed in English and then appropriately translated into the language of each participating country. A total of 378/710 (53.2%) students participated in the study. They attended from 390 to 810h of lessons, while clinical experience ranged from 162 to 536h. The students reported a mean average age of 21.4 (Confidence of Interval [CI] 95%, 21.0-22.3) and foreign students were limited in number (on average 3.7%). The students reported adopting mainly individual learning strategies (92.9%), duplicating notes or lecture notes prepared by professors (74.4%), and concentrating their study before exams (74.6%). The majority reported experiencing learning difficulties (49.7%) and a lack of academic support (84.9%). Around 33.2% reported economic difficulties and the need to work while studying nursing on average for 24h/week. Personal expectations regarding the nursing role were different (45.6%) than the role encountered during the 1st year, as learning workloads were higher (57.2%) with regard to expectations. Around one-third of students reported the intention to leave nursing education while the proportion of those reporting early academic failure was on average 5.6%. More strategies

  18. [Melanoma: from molecular studies to the treatment breakthrough].

    2013-01-01

    Melanoma holds a leading position in the mortality from skin tumors. Standard treatment of metastatic melanoma allows tumor remission to be achieved only in a small subset of patients. Studies on melanoma molecular pathogenesis led to the identification of several causative genetic events and, consequently, to the development of novel targeted drugs. More than a half of melanomas contain amine acid substitutions in serine-threonine kinase BRAF. Clinical trials involving specific BRAF inhibitors--vemurafenib and dabrafenib--demonstrated high efficacy of these agents towards BRAF-mutated melanoma. MEK inhibitors may show activity against both BRAF--and NRAS-driven tumors. Mucosal and acral melanomas frequently contain mutation in KIT receptor and can be successfully treated by imatinib. There are novel therapeutic monoclonal antibodies targeted against immunosuppressive molecules CTLA4, PD-1 and PD-L1. In some instances these drugs allow to obtain exceptionally prolonged responses. Whole genome sequencing led to the identification of new melanoma genes, e.g. GRIN2A, TRRAP, PREX2, RAC1, STK19, PPP6C, etc. Molecular testing, especially BRAF mutation analysis, has become a mandatory part of melanoma diagnosis. Nevertheless, despite the revolution in melanoma treatment, the prevention of excessive ultraviolet exposure, cancer awareness and early diagnosis remain the main tools for the management of this disease.

    Oil spills have become one of the most serious environmental and ecological problems owing to the growth of oil exploration, production and transportation. Millions of gallons of crude oil and refined products are spilled into marine waters worldwide each year. Large volumes of surfactants are applied to the ocean as a remediation strategy. Environmental and toxicity issues arise when such a voluminous amounts of chemical surfactants are applied. One prospective solution to this problem is to use greener surfactants that possess excellent biodegradation and toxicity characteristics relative to existing classes of commonly used surfactants. In this context, we are interested in designing and developing greener surfactants that are patterned after naturally occurring glycolipids. In the present work, we concentrate on one of the more commonly studied glycolipid, rhamnolipid (Rha1C10C10) . Despite the available experimental data, the molecular structure, shape and geometry of micelles formed by rhamnolipid is unknown. Molecular Dynamics (MD) simulations were performed to understand the aggregation behavior of rhamnolipids in aqueous solution and at air-water interface. All calculations were performed in NPT ensembles at 300 K using NAMD 2.8, a parallel code designed for high-performance simulation of large biological macromolecule using the CHARMM force field. The results obtained from MD simulations on the aggregation of rhamnolipids in water and at air-water interface will be presented.

    Using classical equilibrium molecular dynamics simulations and applying the original Tersoff interatomic potential, we study the thermal transport property of the latest two dimensional carbon allotrope, penta-graphene. It is predicted that its room-temperature thermal conductivity is about 167 W/mK, which is much lower than that of graphene. With normal mode decomposition, the accumulated thermal conductivity with respect to phonon frequency and mean free path is analyzed. It is found that the acoustic phonons make a contribution of about 90% to the thermal conductivity, and phonons with mean free paths larger than 100 nm make a contribution over 50%. We demonstrate that the remarkably lower thermal conductivity of penta-graphene compared with graphene results from the lower phonon group velocities and fewer collective phonon excitations. Our study highlights the importance of structure-property relationship and provides better understanding of thermal transport property and valuable insight into thermal management of penta-graphene.

    CHOICE (CHanges to treatment and Outcomes in patients with type 2 diabetes initiating InjeCtablE therapy) assessed patterns of exenatide bid and initial insulin therapy usage in clinical practice in six European countries and evaluated outcomes during the study. CHOICE was a 24-month, prospective, noninterventional observational study. Clinical and resource use data were collected at initiation of first injectable therapy (exenatide bid or insulin) and at regular intervals for 24 months. Costs were evaluated from the national health care system perspective at 2009 prices. A total of 2515 patients were recruited. At the 24-month analysis, significant treatment change had occurred during the study in 42.2% of 1114 eligible patients in the exenatide bid cohort and 36.0% of 1274 eligible patients in the insulin cohort. Improvements in glycemic control were observed over the course of the study in both cohorts (P bid cohort (P bid cohort and €3265.5 in the insulin cohort (€1791.9 versus €2465.5 due to costs other than those of injectable therapy). When baseline direct cost and patients' and disease characteristics were controlled for, mean direct costs differed by country (P bid, compared with insulin, therapy was compensated for by lower mean costs of other health service utilization. Costs associated with exenatide bid or insulin initiation varied across countries, highlighting the need to avoid generalization of resource use and cost implications of a particular therapy when estimated in specific country settings.

  7. Study of correlations in molecular motion by multiple quantum NMR

    1981-11-01

    Nuclear magnetic resonance is a very useful tool for characterizing molecular configurations through the measurement of transition frequencies and dipolar couplings. The measurement of spectral lineshapes, spin-lattice relaxation times, and transverse relaxation times also provide us with valuable information about correlations in molecular motion. The new technique of multiple quantum nuclear magnetic resonance has numerous advantages over the conventional single quantum NMR techniques in obtaining information about static and dynamic interactions of coupled spin systems. In the first two chapters, the theoretical background of spin Hamiltonians and the density matrix formalism of multiple quantum NMR is discussed. The creation and detection of multiple quantum coherence by multiple pulse sequence are discussed. Prototype multiple quantum spectra of oriented benzene are presented. Redfield relaxation theory and the application of multiple quantum NMR to the study of correlations in fluctuations are presented. A specific example of an oriented methyl group relaxed by paramagnetic impurities is studied in detail. The study of possible correlated motion between two coupled methyl groups by multiple quantum NMR is presented. For a six spin system it is shown that the four-quantum spectrum is sensitive to two-body correlations, and serves a ready test of correlated motion. The study of the spin-lattice dynamics of orienting or tunneling methyl groups (CH/sub 3/ and CD/sub 3/) at low temperatures is presented. The anisotropic spin-lattice relaxation of deuterated hexamethylbenzene, caused by the sixfold reorientation of the molecules, is investigated, and the NMR spectrometers and other experimental details are discussed.

Sofia 2015 The 11th Congress of South-East European Studies took place in Sofia, Bulgaria, between 31 August and 4 September 2015. It was organised by the International Association for Southeast European Studies (orig. in French: AIESEE – Associacion Internationale d’ Études du Sud-Est Européen. South-Eastern Europe is an area looked upon by world powers with a large amount of ambivalence. As the region’s states are not considered to be key global players, the events that occur in this part of the continent draw interest that is cyclical in nature and that is usually triggered by cyclical issues, too. Though relatively small, the area has been a point of interest for many researchers for over 100 years due to its ethnic diversity and the related inherent multi-nationality the scale of which is not encountered anywhere else in Europe. The cultural, linguistic, and religious pluralism of this region often produces specific social amalgams. With the cyclical interest aside, for a little more than a century the main European (and not only European political powers have been making efforts to exert influence in the region, understanding the significance of its geographic location, where East meets West. Regardless of the changing dynamics of interest in South-Eastern Europe, the region will certainly remain one of the most fascinating focus areas for researchers and academics across the world, who will meet again not in five, but in four years at another congress this time to be held in Romanian Constanţa to discuss issues and topics related to this corner of the world.   11.

    Spiritual care is expected of nurses, but it is not clear how undergraduates can achieve competency in spiritual care at point of registration as required by nursing/midwifery regulatory bodies. To describe undergraduate nurses'/midwives' perceptions of spirituality/spiritual care, their perceived competence in delivering spiritual care, and to test out the proposed method and suitability of measures for a larger multinational follow-on study. Cross-sectional, multinational, descriptive survey design. Author administered questionnaires were completed by 86% of the intended convenience sample of 618 undergraduate nurses/midwives from 6 universities in 4 European countries in 2010. Students held a broad view of spirituality/spiritual care and considered themselves to be marginally more competent than not in spiritual care. They were predominantly Christian and reported high levels of spiritual wellbeing and spiritual attitude and involvement. The proposed method and measures were appropriate and are being used in a follow-on study. The following are worthy of further investigation: whether the pilot study findings hold in student samples from more diverse cultural backgrounds; whether students' perceptions of spirituality can be broadened to include the full range of spiritual needs patients may encounter and whether their competence can be enhanced by education to better equip them to deliver spiritual care; identification of factors contributing to acquisition of spiritual caring skills and spiritual care competency. © 2013.

    A cross-sectional school-based survey study (N=13,284; 53% females; mean age 15.8±0.7) of 14-17-year-old adolescents was conducted in seven European countries (Greece, Spain, Poland, Germany, Romania, the Netherlands, and Iceland). The aim of the study was to investigate the prevalence of Internet addictive behavior (IAB) and related psychosocial characteristics among adolescents in the participating countries. In the study, we distinguish two problematic groups: adolescents with IAB, characterized by a loss of control over their Internet use, and adolescents "at risk for IAB," showing fewer or weaker symptoms of IAB. The two groups combined form a group of adolescents with dysfunctional Internet behavior (DIB). About 1% of adolescents exhibited IAB and an additional 12.7% were at risk for IAB; thus, in total, 13.9% displayed DIB. The prevalence of DIB was significantly higher among boys than among girls (15.2% vs. 12.7%, pgaming) at least 6 days/week was associated with greater probability of displaying DIB. Multiple logistic regression analysis indicated that DIB was more frequent among adolescents with a lower educational level of the parents, earlier age at first use of the Internet, and greater use of social networking sites and gaming sites. Multiple linear regression analysis showed that externalizing (i.e., behavioral) and internalizing (i.e., emotional) problems were associated with the presence of DIB.

    Full Text Available Background and objectives: More than 40 different alkaloids have been obtained from opium the most important of which are morphine, codeine, papaverine, noscapine and tabaine. Opioid alkaloids produce analgesia by affecting areas of the brain that have peptides with pharmacological pseudo-opioid properties. These alkaloids show important effects on some intracellular peptides like mu, delta, and kappa receptors. Therefore, studying the effects of these alkaloids on different receptors is essential. Methods: Molecular docking is a well-known method in exploring the protein-ligand interactions. In this research, five important alkaloids were docked to crystal structure of human mu opioid receptor (4DKL, human delta opioid receptor (4EJ4 and human kappa opioid receptor (4DJH which were retrieved from protein databank. The 3D-structures of alkaloids were drawn by chembiooffice2010 and minimized with hyperchem package and submitted to molecular docking utilizing autodock-vina. Flexibility of the proteins was considered. The docking studies were performed to compare the affinity of these five alkaloids to the mentioned receptors. Results: We computationally docked each alkaloid compound onto each receptor structure and estimated their binding affinity based on dock scores. Dock score is a criteria including binding energy which utilized here for prediction and comparison of the binding affinities. Binding interactions of the docked alkaloids in receptor pockets were also visually inspected and compared. Conclusion: In this approach, using docking study as a computational method provided a valuable insight of opioid receptor pocket structures which would be essential to design more efficient drugs in pain managements and addiction treatments.

  12. In-pile testing of HCPB submodules. Feasibility study for the European Blanket project. Final report

    Full size module systems of the candidate DEMO blanket concepts selected for the European Blanket Project (EBP) will be tested in ITER, presently called Test Blanket modules (TBM). The Helium Cooled Pebble Bed (HCPB) is one of the two concepts developed in the European Union (EU). This development path consists of several scaling steps, including integral testing of a subsized module at realistic operation conditions. As part of the HCPB development work for the TBMs, ECN performed jointly with JRC/IAM at Petten a feasibility study for irradiation tests of subsized HCPB modules. The first stage of the study was concluded with a report on the conceptual design of an in-pile test of a single submodule with a helium cooling loop. Such test was considered technically feasible, but would require significant project duration and expenditures. Further development of detailed objectives for in-pile tests was recommended, in particular in view of the different parameters for the HCPB-ITM and DEMO-concept. This objective has been modified by the EBP in fall 1997. For the final stage of the study the test objective has been: the in-pile testing of the thermal/mechanical behaviour of the HCPB ceramic breeder beds, while giving lower priority to tritium transport issues (release, permeation). Several configuration options in the High Flux Reactor (HFR) in Petten, Netherlands, to perform in-pile test of HCPB submodules have been considered. Neutronics analyses along with thermal and structural analyses have been made for selected options and several HFR peripheral in-tank positions. These pre-design analyses show that the whole range of breeder bed power densities and temperature levels, which are relevant to the HCPB DEMO and BTM designs, can be reached with the options presented. The options are all cooled by the reactor coolant flow. The use of an helium loop is not compulsory and is considered as an unnecessary complication with regard to the present test objectives

    Austerity measures and health-system redesign to minimise hospital expenditures risk adversely affecting patient outcomes. The RN4CAST study was designed to inform decision making about nursing, one of the largest components of hospital operating expenses. We aimed to assess whether differences in patient to nurse ratios and nurses' educational qualifications in nine of the 12 RN4CAST countries with similar patient discharge data were associated with variation in hospital mortality after common surgical procedures. For this observational study, we obtained discharge data for 422,730 patients aged 50 years or older who underwent common surgeries in 300 hospitals in nine European countries. Administrative data were coded with a standard protocol (variants of the ninth or tenth versions of the International Classification of Diseases) to estimate 30 day in-hospital mortality by use of risk adjustment measures including age, sex, admission type, 43 dummy variables suggesting surgery type, and 17 dummy variables suggesting comorbidities present at admission. Surveys of 26,516 nurses practising in study hospitals were used to measure nurse staffing and nurse education. We used generalised estimating equations to assess the effects of nursing factors on the likelihood of surgical patients dying within 30 days of admission, before and after adjusting for other hospital and patient characteristics. An increase in a nurses' workload by one patient increased the likelihood of an inpatient dying within 30 days of admission by 7% (odds ratio 1·068, 95% CI 1·031-1·106), and every 10% increase in bachelor's degree nurses was associated with a decrease in this likelihood by 7% (0·929, 0·886-0·973). These associations imply that patients in hospitals in which 60% of nurses had bachelor's degrees and nurses cared for an average of six patients would have almost 30% lower mortality than patients in hospitals in which only 30% of nurses had bachelor's degrees and nurses cared

    Full Text Available This paper is an analysis of milk support policy in the European Union and in Turkey. Turkey’s adaptation of its milk policy to the Common Agricultural Policy of European Union is on the agenda since Turkey has been a candidate country in 1999. Regarding that the Common Agricultural Policy has been reformed many times, Turkey has to adapt its milk sector to a changing policy. Turkey, on the other hand, pursues different support policy in the milk sector. The producers, who are registered in the Farming Registration System, receive milk incentive premiums. There are no similarities between Turkish milk support policy and European Union’s milk support policy. According to the last progress reports, Turkey has to improve Farming Registration System. Turkey has to adjust milk production process to the European Union standards. Furthermore, in the accession process, Turkey plans to increase consumption and also needs to promote milk and milk products producers’ organizations.

    An accurate molecular diagnosis of diabetes subtype confers clinical benefits; however, many individuals with monogenic diabetes remain undiagnosed. Biomarkers could help to prioritise patients for genetic investigation. We recently demonstrated that high-sensitivity C-reactive protein (hs......CRP) levels are lower in UK patients with hepatocyte nuclear factor 1 alpha (HNF1A)-MODY than in other diabetes subtypes. In this large multi-centre study we aimed to assess the clinical validity of hsCRP as a diagnostic biomarker, examine the genotype-phenotype relationship and compare different hsCRP assays....... High-sensitivity CRP levels were analysed in individuals with HNF1A-MODY (n = 457), glucokinase (GCK)-MODY (n = 404), hepatocyte nuclear factor 4 alpha (HNF4A)-MODY (n = 54) and type 2 diabetes (n = 582) from seven European centres. Three common assays for hsCRP analysis were evaluated. We excluded 121...

    A density functional theory based Car-Parrinello molecular dynamics simulation of liquid dimethyl carbonate, an environmentally benign solvent, has been carried out to study its structure and dynamics. Conformational excitations of the molecule have been probed in both its gas and liquid phases. While the cis-cis conformer is the global energy minimum and, thus, the most predominant, at ambient conditions a few percent of molecules are present in the cis-trans conformation as well. The latter possesses a dipole moment of around 4.5 D in the liquid state, a value that is nearly five times as large as that for the cis-cis conformer. Dipole-dipole interactions play a crucial role in the formation of small hydrogen bonded clusters of cis-trans conformers in the liquid. The vibrational spectrum of liquid dimethyl carbonate has been obtained from the trajectory and is shown to agree quite well with available experimental data.

    The purpose of an F1000 review is to reflect on the bigger picture, exploring controversies and new concepts as well as providing opinion as to what is limiting progress in a particular field. We reviewed about 200 titles published in 2015 that included reference to 'skeletal muscle, exercise, and ageing' with the aim of identifying key articles that help progress our understanding or research capacity while identifying methodological issues which represent, in our opinion, major barriers to progress. Loss of neuromuscular function with chronological age impacts on both health and quality of life. We prioritised articles that studied human skeletal muscle within the context of age or exercise and identified new molecular observations that may explain how muscle responds to exercise or age. An important aspect of this short review is perspective: providing a view on the likely 'size effect' of a potential mechanism on physiological capacity or ageing.

    The shock response of porous amorphous silica is investigated using classical molecular dynamics, over a range of porosity ranging from fully dense (2.21 g/cc) down to 0.14 g/cc. We observe an enhanced densification in the Hugoniot response at initial porosities above 50 %, and the effect increases with increasing porosity. In the lowest initial densities, after an initial compression response, the systems expand with increased pressure. These results show good agreement with experiments. Mechanisms leading to enhanced densification will be explored, which appear to differ from mechanisms observed in similar studies in silicon.

    A national, Web-based survey of 1,219 African American, Latina/o, Asian American, and European American psychology graduate students revealed both similarities and differences in experiences and perspectives. Mentoring was found to be the strongest predictor of satisfaction across groups. Academic supports and barriers, along with perceptions of diversity within the academic environment, were also important predictors of satisfaction. Students of color perceived less fairness of representation of their ethnic group within psychology than European American students, and a greater linkage between aspects of the graduate school experience and their ethnicity. Limitations of the study and implications for future research and action are discussed.

    De Quervain disease is a common pathology resulting in pain caused by resisted gliding of the abductor pollicis longus and extensor pollicis brevis tendons in the fibro-osseous canal. In a situation of wavering assumptions and expanding medical knowledge, a treatment guideline is useful because it can aid in implementation of best practices, the education of health care professionals, and the identification of gaps in existing knowledge. The aim of this study was to achieve consensus on a multidisciplinary treatment guideline for de Quervain disease. A Delphi consensus strategy was used. A European Delphi consensus strategy was initiated. A systematic review reporting on the effectiveness of surgical and nonsurgical interventions was conducted and published and was used as an evidence-based starting point for this study. In total, 35 experts (hand therapists and hand surgeons selected by the national member associations of their European federations and physical medicine and rehabilitation physicians) participated in the Delphi consensus strategy. Each Delphi round consisted of a questionnaire, an analysis, and a feedback report. Consensus was achieved on the description, symptoms, and diagnosis of de Quervain disease. The experts agreed that patients with this disorder should always receive instructions and that these instructions should be combined with another form of treatment and should not be used as a sole treatment. Instructions combined with nonsteroidal anti-inflammatory drugs (NSAIDs), splinting, NSAIDs plus splinting, corticosteroid injection, corticosteroid injections plus splinting, or surgery were considered suitable treatment options. Details on the use of instructions, NSAIDs, splinting, corticosteroid injections, and surgery were described. Main factors for selecting one of these treatment options (ie, severity and duration of the disorder, previous treatments given) were identified. A relationship between the severity and duration of the disorder

    Saffron, the spice produced from the red stigmas of the flower of Crocus sativus L. is a frequent target of fraud and mislabeling practices that cannot be fully traced using the ISO 3632 trade standard specifications and test methods. A molecular approach is proposed herein as a promising branding strategy for the authentication of highly esteemed saffron brands such as the Greek Protected Designation of Origin (PDO) "Krokos Kozanis". Specific ISSR (inter-simple sequence repeat) markers were used to assess for the first time, the within species variability of several populations of C. sativus L. from the cultivation area of "Krokos Kozanis" as well as the potential differences with the band pattern produced by other Crocus species. Then, species-specific markers were developed taking advantage of an advanced molecular technique such as the HRM analysis coupled with universal DNA barcoding regions (trnL) (Bar-HRM) and applied to saffron admixtures with some of the most common plant adulterants (Calendula officinalis, Carthamus tinctorius, Gardenia jasminoides, Zea mays and Curcuma longa). The sensitivity of the procedure was tested for turmeric as a case study whereas HPLC-fluorescence determination of secondary metabolites was also employed for comparison. The overall results indicated that the Bar-HRM approach is quite effective in terms of specificity and sensitivity. Its effectiveness regarding the detection of turmeric was comparable to that of a conventional HPLC method (0.5% vs 1.0%, w/w). Yet, the proposed DNA-based method is much faster, cost-effective and can be used even by non-geneticists, in any laboratory having access to an HRM-capable real-time PCR instrumentation. It can be, thus, regarded as a strong analytical tool in saffron authentication studies. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Molecular profiling of advanced non-small-cell lung cancer (NSCLC) is recommended according to European and Italian guidelines. However, molecular routine assessment remains still heterogeneous. This observational study aimed to take a picture of the real clinical practice in molecular testing and therapeutic choices in advanced Italian NSCLCs. This study prospectively enrolled newly diagnosed advanced or recurrent NSCLCs referred to 38 Italian centres, from November 2014 to November 2015. Information regarding molecular profiling and treatment choices were collected. Description of patients' outcome included overall survival (OS), progression-free survival in first (PFS1) and second-line (PFS2). Among 1787 patients enrolled, 1388 (78%) performed at least one molecular analysis during the history of disease: 76% were tested for EGFR, 53% for ALK, 27% for KRAS, 16% for ROS1, 14% for BRAF, 5% for HER2, 4% for MET and 1% for FGFR. The remaining 399 patients (22.3%) did not receive any molecular test. Among patients receiving at least one molecular analysis, 583 (42%) presented a molecular alteration. Considering EGFR mutated and/or ALK rearranged patients (402), for which target agents were routinely reimbursed at time of study in Italy, the 86% received a personalized treatment as first and/or second line: the 90% (286) of EGFR mutants received an EGFR tyrosine kinase inhibitor, mostly gefitinib (41.1%) or afatinib (36.4%) while 74% (62) of ALK translocated patients received an ALK inhibitor, mostly crizotinib (64%). Median OS was 9.34 months (95% CI 8.62-10.0), median PFS1 was 4.61 months (95%CI 4.31-4.84) and median PFS2 was 2.76 months (95%CI 2.57-3.19). In the Italian clinical practice, routine molecular assessment was largely applied in NSCLC patients, according to national guidelines, but a low level of ALK test was reached. Most of EGFR mutants an ALK rearranged patients received a personalized treatment as first and/or second line. Copyright © 2017 Elsevier

    To assess the relationship between parental education level and the consumption frequency of obesity-related foods in European children. The analysis was based on data from the cross-sectional baseline survey of a prospective cohort study. The effects of parental education on food consumption were explored using analysis of covariance and logistic regression. Primary schools and pre-schools of selected regions in Italy, Estonia, Cyprus, Belgium, Sweden, Hungary, Germany and Spain. Participants (n 14,426) of the IDEFICS baseline cohort study aged 2 to 9 years. Parental education level affected the intake of obesity-related foods in children. Children in the low and medium parental education level groups had lower odds of more frequently eating low-sugar and low-fat foods (vegetables, fruits, pasta/noodles/rice and wholemeal bread) and higher odds of more frequently eating high-sugar and high-fat foods (fried potatoes, fruits with sugar and nuts, snacks/desserts and sugared beverages; P education level was associated with intakes of sugar-rich and fatty foods among children, while high parental education level was associated with intakes of low-sugar and low-fat foods. These findings should be taken into account in public health interventions, with more targeted policies aiming at an improvement of children's diet.

  12. Ground-based studies of tropisms in hardware developed for the European Modular Cultivation System (EMCS)

    Correll, Melanie J.; Edelmann, Richard E.; Hangarter, Roger P.; Mullen, Jack L.; Kiss, John Z.

    Phototropism and gravitropism play key roles in the oriented growth of roots in flowering plants. In blue or white light, roots exhibit negative phototropism, but red light induces positive phototropism in Arabidopsis roots. The blue-light response is controlled by the phototropins while the red-light response is mediated by the phytochrome family of photoreceptors. In order to better characterize root phototropism, we plan to perform experiments in microgravity so that this tropism can be more effectively studied without the interactions with the gravity response. Our experiments are to be performed on the European Modular Cultivation System (EMCS), which provides an incubator, lighting system, and high resolution video that are on a centrifuge palette. These experiments will be performed at μg, 1g (control) and fractional g-levels. In order to ensure success of this mission on the International Space Station, we have been conducting ground-based studies on growth, phototropism, and gravitropism in experimental unique equipment (EUE) that was designed for our experiments with Arabidopsis seedlings. Currently, the EMCS and our EUE are scheduled for launch on space shuttle mission STS-121. This project should provide insight into how the blue- and red-light signaling systems interact with each other and with the gravisensing system.

    2015-09-01

    Full Text Available The purpose of this study was to analyse players’ positional variability during the 2012 UEFA European Championship by applying principal component analysis (PCA to data gathered from heat maps posted on the UEFA website. We analysed the teams that reached the finals and semi-finals of the competition. The players’ 2D coordinates from each match were obtained by applying an image-processing algorithm to the heat maps. With all the players’ 2D coordinates for each match, we applied PCA to identify the directions of greatest variability. Then, two orthogonal segments were centred on each player’s mean position for all matches. The segments’ directions were driven by the eigenvectors of the PCA, and the length of each segment was defined as one standard deviation around the mean. Finally, an ellipse was circumscribed around both segments. To represent player variability, segment lengths and elliptical areas were analysed. The results demonstrate that Portugal exhibited the lowest variability, followed by Germany, Spain and Italy. Additionally, a graphical representation of every player’s ellipse provided insight into the teams’ organisational features throughout the competition. The presented study provides important information regarding soccer teams’ tactical strategy in high-level championships that allows coaches to better control team organisation on the pitch.

  14. Experimental studies of food choices and palatability responses in European subjects exposed to the Umami taste.

    In the Western world, consumers have only recently learned to discriminate the Umami taste, although they have enjoyed its contribution to the palatability of traditional dishes for centuries. The flavor enhancing properties of MSG have been scientifically investigated in European subjects. By adding MSG to such foods as soups, their content in sodium can be decreased without altering palatability, thus favoring a net decrease in sodium intake. Consumers presented with a novel food often have to get accustomed to the new taste before they acquire a preference for the food. A study showed that when such novel foods are added with some appropriate amount of MSG, consumers acquire a preference for them more rapidly. In elderly persons, the addition of MSG to nutritionally valuable foods (soups, vegetables, starches) did induce an increase of intake of MSG-added foods. Total meal size, however, was not affected, since the increased intake of MSG-containing foods was followed by a decreased consumption of foods served later in the meal, such as desserts. The same observations were repeated in hospitalized diabetic patients. Again, the patients ingested more healthy MSG-containing foods and less of other foods, with the same total meal energy intake. These two studies suggested that MSG could be used to stimulate appropriate food choices in certain populations.

Individually assigned levels of nitrogen dioxide, nitrogen oxides, particulate matter ≤ 2.5 μm (PM2.5), absorbance of PM2.5 (PM2.5abs), PM10, PMcoarse, and two indicators of residential proximity to highly trafficked roads were obtained under a standard exposure protocol (European Study of Cohorts for Air Pollution Effects-ESCAPE study) in the Stockholm area (Sweden), the Ausburg and Ruhr area (Germany), and the Girona area (Spain). We used linear regression and meta-analyses to examine the association between long-term exposure to air pollution and CIMT. The meta-analysis with 9,183 individuals resulted in an estimated increase in CIMT (geometric mean) of 0.72% (95% CI: -0.65%, 2.10%) per 5-μg/m3 increase in PM2.5 and 0.42% (95% CI: -0.46%, 1.30%) per 10-5/m increase in PM2.5abs. Living in proximity to high traffic was also positively but not significantly associated with CIMT. Meta-analytic estimates for other pollutants were inconsistent. Results were similar across different adjustment sets and sensitivity analyses. In an extended meta-analysis for PM2.5 with three other previously published studies, a 0.78% (95% CI: -0.18%, 1.75%) increase in CIMT was estimated for a 5-μg/m3 contrast in PM2.5. Using a standardized exposure and analytical protocol in four European cohorts, we found that cross-sectional associations between CIMT and the eight ESCAPE markers of long-term residential air pollution exposure did not reach statistical significance. The additional meta-analysis of CIMT and PM2.5 across all published studies also was positive but not significant.

    South Asian children and adults have a more adipose body composition compared with those of European ancestry. This is thought to be related to their increased risk of metabolic disorders. However, little is known about how early in life such differences are manifest. To determine whether there are differences in fat mass (FM) and fat-free mass (FFM) between UK-born South Asians and White Europeans in infancy. Design A cross-sectional study of 30 South Asian and 30 White European infants aged 6-12 weeks. Mothers were recruited from clinics in London, and infants' FM and FFM were determined using air-displacement plethysmography (PeaPod(®)). In early infancy South Asians had less FFM than White Europeans [0.34 kg less, 95% confidence interval (CI): 0.15, 0.52], with a considerably weaker indication of them also having more FM (0.02 kg more, 95% CI: -0.14, 0.18). These differences persisted when the overall smaller body size of South Asian infants was taken into account. For a given total infant weight, the balance of body composition of South Asians was shifted by 0.16 kg (95% CI: 0.06, 0.25) from FFM to FM. The ethnic differences in the amount of FFM were almost completely accounted for by ethnic differences in the rate of growth in utero and length of gestation. The characteristic differences in body composition observed between adult South Asians and White Europeans are apparent in early infancy. Of particular note is that this is the first study to demonstrate that South Asians compared with White Europeans have reduced FFM in infancy. The early manifestation of this phenotype suggests that it is either genetic and/or determined through exposure to maternal physiology, rather than a consequence of behaviours or diet in childhood or at older ages.

    The molecular mechanism of the binding of norfloxacin (NRF) to trypsin was investigated by fluorescence, synchronous fluorescence and UV-vis absorbance spectroscopy and molecular modeling at physiological conditions. The quenching mechanism and the binding mode were investigated in terms of the association constants and basic thermodynamic parameters. The results of spectroscopic measurements suggested that NRF have a strong ability to quench the intrinsic fluorescence of trypsin through static quenching procedure. Moreover, fluorescence experiments were also performed at different values of pH to elucidate the effect of pH on the binding. The NRF-trypsin complex was stabilized by hydrophobic forces and hydrogen bonding, via tryptophan residue as indicated from the thermodynamic parameters, which was consistent with the results of molecular docking and accessible surface area calculations.

    Full Text Available Abstract Background Young individuals are the age group with the highest risk of car accidents. One of main explanations relies on the use of psychoactive substances (alcohol, illegal and medicinal drugs, which are known to be major risk factors of road accidents, and whose consumption is almost universally more common among younger drivers. Although the correlation between psychoactive substances use and decrease in driving performance has been established in controlled experimental or laboratory settings, few studies were conducted in naturalistic circumstances. The TEND by Night project has been designed to evaluate the relationship between driving performance and psychoactive substances assumption in young drivers enrolled at typical places of consumption. Methods/Design The TEND by Night project, endorsed by the European Commission, is a multidisciplinary, multi-centric, cross-sectional study conducted in six European countries (Italy, Belgium/Netherlands, Bulgaria, Spain, Poland and Latvia. The study population consists of 5000 young drivers aged 16-34 years, attending recreational sites during weekend nights. The intervention is based on the portal survey technique and includes several steps at the entrance and exit of selected sites, including the administration of semi-structured questionnaires, breath alcohol test, several drug assumption test, and measurement of the reaction time using a driving simulator. The main outcome is the difference in reaction time between the entrance and exit of the recreation site, and its correlation with psychoactive substances use. As a secondary outcome it will be explored the relationship between reaction time difference and the amount of consumption of each substance. All analyses will be multivariate. Discussion The project methodology should provide some relevant advantages over traditional survey systems. The main strengths of the study include the large and multicentric sample, the objective

    2016-08-01

    Full Text Available This study explored the social science-orientated literature on genetically modified (GM crops in Europe and compared it with the corresponding literature on GM crops in African contexts, in order to determine the nature and extent of north-south cross-fertilisation in the literature. A total of 1625 papers on GM crops and agriculture falling within the ‘social science and humanities’ subject area in the Scopus abstract and citation database of peer-reviewed literature were analysed for major trends relating to geographical areas. More detailed analysis was performed on papers discussing African (56 papers and European (127 papers contexts. The analysis revealed that studies on policy and politics were common in both strands of the literature, frequently focusing on effects of the relatively restrictive European Union regulations on GM crops. There were also clear differences, however. For example, papers focusing on Africa frequently examined farm-level impacts and production, while this theme was almost non-existent in the Europe literature. It focused instead on policy impacts on trade and consumer attitudes to GM products. The lack of farm-level studies and of empirical studies in general in the European literature indicates a need for empirical research on GM crops in European farming. Social science research on GM crop production in Europe could draw lessons from the African literature.

Higher education and business communication promotion and synergy are being dedicated as a prior target for all EU and EU member countries to be able to continue increasing employment, productivity, as well as social connections. The research of the enterprise and its stimulation in higher education (using higher education and business collaboration is not deep enough, although the enterprise’s multiple phenomenon were analysed from many perspectives. It is being planned to raise EU’s investments to youth much more compared to other main parts of the budget in 2014-2020. Analysis of European Union documents and Lithuanian case studies was chosen on purpose according to the enterprise’s created added value for European development. Realization, creativity, initiative, motivation, taking risks, planning and reaching personal goals are the main parts of the enterprise. Development of these skills in higher education is becoming very important because of “the advantage of the competitiveness is being determined by country‘s social education therefore the effective usage of human recourses is the most important part seeking to increase stabile economical and social well being.” Research of the EU’s and Lithuania’s national documentation and scientific literature review of entrepreneurship in higher education identifies the current enterprise position in education. According to the analyses of the documentation and the scientific literature review, the enterprise’s evaluation level was appointed. The new beginning of the enterprise in higher education is being started after the research was done and centrepiece’s promotion was critically evaluated in the EU and Lithuania.

    Biofuels are a well-known alternative to the largely used fossil-derived fuels, however the competition with food production is an ethical dilemma. Fortunately a solution is offered by second-generation biofuels which can be produced from agricultural waste or, more specifically, from plant cell wall polysaccharides. The conversion process involves typically enzymatic hydrolysis of lignocellulosic biomass and then separation of its constituent sugars that are further fermented to produce ethanol. Over the years several technologies have been developed that allow this conversion process to occur and the objective is now to make this process cost-competitive in today's markets. We observe that reduction of enzymatic efficiency in the presence of gluco-oligosaccharides is associated with a loss of the enzyme's flexibility, the latter being required to bind new substrate, while the presence of manno-oligosaccharides does not pose this problem. Molecular dynamics simulations identify key contacts between substrates and the enzyme catalytic pocket that might be modified through site-directed mutagenesis to prevent loss of enzymatic efficiency. Based on previous experimental studies and the new molecular dynamics data, we suggest that cellohexaose in the active site pocket slows down or even inhibits Man5B enzymatic activity. The assumption of such a mechanism is reasonable since when the gluco-oligosaccharide substrate is attached to the catalytic pocket it takes much longer to leave the pocket and thus prevents other substrates from reaching the active site. The insight is of crucial importance since the inhibition of enzymes by the enzymatic product or by an unsuitable substrate is a major technological problem in reducing the competitiveness of second-generation biofuel production.

    The DNA barcode has been widely used in species identification and phylogenetic analysis since 2003, but there have been no reports in Demodex. In this study, to obtain an appropriate DNA barcode for Demodex, molecular identification of Demodex caprae based on mitochondrial cox1 was conducted. Firstly, individual adults and eggs of D. caprae were obtained for genomic DNA (gDNA) extraction; Secondly, mitochondrial cox1 fragment was amplified, cloned, and sequenced; Thirdly, cox1 fragments of D. caprae were aligned with those of other Demodex retrieved from GenBank; Finally, the intra- and inter-specific divergences were computed and the phylogenetic trees were reconstructed to analyze phylogenetic relationship in Demodex. Results obtained from seven 429-bp fragments of D. caprae showed that sequence identities were above 99.1% among three adults and four eggs. The intraspecific divergences in D. caprae, Demodex folliculorum, Demodex brevis, and Demodex canis were 0.0-0.9, 0.5-0.9, 0.0-0.2, and 0.0-0.5%, respectively, while the interspecific divergences between D. caprae and D. folliculorum, D. canis, and D. brevis were 20.3-20.9, 21.8-23.0, and 25.0-25.3, respectively. The interspecific divergences were 10 times higher than intraspecific ones, indicating considerable barcoding gap. Furthermore, the phylogenetic trees showed that four Demodex species gathered separately, representing independent species; and Demodex folliculorum gathered with canine Demodex, D. caprae, and D. brevis in sequence. In conclusion, the selected 429-bp mitochondrial cox1 gene is an appropriate DNA barcode for molecular classification, identification, and phylogenetic analysis of Demodex. D. caprae is an independent species and D. folliculorum is closer to D. canis than to D. caprae or D. brevis.

    Full Text Available Glucose oxidase (GOx is an enzyme produced by Aspergillus, Penicillium and other fungi species. It catalyzes the oxidation of β-d-glucose (by the molecular oxygen or other molecules, like quinones, in a higher oxidation state to form d-glucono-1,5-lactone, which hydrolyses spontaneously to produce gluconic acid. A coproduct of this enzymatic reaction is hydrogen peroxide (H2O2. GOx has found several commercial applications in chemical and pharmaceutical industries including novel biosensors that use the immobilized enzyme on different nanomaterials and/or polymers such as polyethylenimine (PEI. The problem of GOx immobilization on PEI is retaining the enzyme native activity despite its immobilization onto the polymer surface. Therefore, the molecular dynamic (MD study of the PEI ligand (C14N8_07_B22 and the GOx enzyme (3QVR was performed to examine the final complex PEI-GOx stabilization and the affinity of the PEI ligand to the docking sites of the GOx enzyme. The docking procedure showed two places/regions of major interaction of the protein with the polymer PEI: (LIG1 of −5.8 kcal/mol and (LIG2 of −4.5 kcal/mol located inside the enzyme and on its surface, respectively. The values of enthalpy for the PEI-enzyme complex, located inside of the protein (LIG1 and on its surface (LIG2 were computed. Docking also discovered domains of the GOx protein that exhibit no interactions with the ligand or have even repulsive characteristics. The structural data clearly indicate some differences in the ligand PEI behavior bound at the two places/regions of glucose oxidase.

    To compare dietary intakes of European, Māori, Pacific, and Asian men and women living in Auckland. Daily nutrient intakes were calculated from a self-administered food frequency questionnaire from participants in a cross-sectional health screening study carried out between 2002 and 2003. Participants were 4,007 Māori, Pacific, Asian and European people (1,915 men, 2,092 women) aged 35 to 74 years. Compared with Europeans, Māori and Pacific men had higher total energy intakes per day, while Asians had lower intakes. A similar pattern was observed for carbohydrate and fat consumption. While protein and cholesterol consumption tended to be lower in Europeans than the other three ethnic groups, alcohol consumption and calcium intakes were highest among Europeans. Many of the differences between ethnic groups were attenuated when nutrient consumption was expressed as their percentage contribution to total energy intake suggesting that total food consumption was the major determinant of ethnic differences in nutrient intakes. There were substantial differences in dietary habits, food selections and cooking practices between European, Māori, Pacific and Asian participants. However, the observed differences were in the area of serving sizes and frequency of consumption of certain foods than to major differences in the range of foods and nutrients consumed or the percentage contribution of carbohydrate, fat or protein to total energy intake. The development of strategies to reduce serving sizes and the frequency of consumption of certain foods will be required to help address the major nutrition-related health problems in New Zealand.

    This study was conducted to compare attitudes of psychiatrists, other professionals, and laypeople towards compulsory admission and treatment of patients with schizophrenia in different European countries. Three case reports of patients with schizophrenia were presented to N=1,737 persons: 235 in England, 622 in Germany, 319 in Hungary, and 561 in Switzerland; 298 were psychiatrists, 687 other psychiatric or medical professionals, and 752 laypeople. The case reports presented typical clinical situations with refusal of consent to treatment (first episode and social withdrawal, recurrent episode and moderate danger to others and patient with multiple episodes and severe self-neglect). The participants were asked whether they would agree with compulsory admission and compulsory neuroleptic treatment. The rates of agreement varied between 50.8 and 92.1% across countries and between 41.1 and 93.6% across the different professional groups. In all countries, psychologists and social workers supported compulsory procedures significantly less than the psychiatrists who were in tune with laypeople and nurses. Country differences were highly significant showing more agreement with compulsion in Hungary and England and less in Germany and Switzerland (odds ratios up to 4.33). Own history of mental illness and having mentally ill relatives had no major impact on the decisions. Evidence suggests that compulsory procedures are based on traditions and personal attitudes to a considerable degree. Further research should provide empirical data and more definite criteria for indications of compulsive measures to achieve a common ethical framework for those critical decisions across Europe.

We used the Language Development Survey (LDS; Rescorla, 1989) with children (18-35 months) learning European Portuguese (n = 181) and English (n = 206). In both languages, girls had higher vocabulary scores than boys and vocabulary scores increased with age. Portuguese LDS scores were significantly lower than English scores, but the effect size was small. Cross-linguistic concordance of percentage use scores yielded a Q correlation of .50, with 64 of the "top 100" words being exact matches. Cross-linguistic concordance was highest for the youngest age group. In both languages, vocabulary composition in late talkers (children ≥ 24 months with < 50 words) was highly correlated with composition in vocabulary size-matched younger children. Results replicated previous Greek, Korean, and Italian LDS studies. The early lexicons of typical talkers and late talkers contained many of the same words, indicating considerable universality and suggesting good targets for clinical intervention.

    Full Text Available The use of drugs in newborns admitted to NICUs is characterized by a great variability. This widespread phenomenon, observed both within and between different countries, has been highlighted by reporting data on the treatment of neonatal sepsis and PDA throughout Europe: the dosages and the intervals between administrations of ciprofloxacin and fluconazole varied significantly and a wide variation was also observed as regards the use of NSAIDs to treat PDA. Given the unique characteristics of the neonatal population, the use of drugs on an individual basis could be sometimes justified. However, other factors such as the lack of evidence-based guidelines and the common use of drugs in an off-label manner (more than 80% of newborns receive this kind of treatment could contribute to the variability in medicine use, making the neonatal population vulnerable to adverse drug reactions (ADRs and medication errors: the potential ADRs rate, 3 times higher in pediatric wards, is more significantly higher in NICUs and the frequency of medication errors (mostly dose errors widely exceeds the medium value. The differences in clinical practices observed between NICUs need to be addressed at a European level and a multicentre study could be useful to harmonize drug use in newborns.

    A transsexual course of development that starts before puberty (early onset) or during or after puberty, respectively (late onset), may lead to diverse challenges in coping with sexual activity. The authors explored the sexual behavior of 380 adult male-to-female and female-to-male individuals diagnosed according to DSM-IV-TR criteria who had not yet undergone gender-confirming interventions. Data originated from the European Network for the Investigation of Gender Incongruence Initiative, conducted in Belgium, Germany, The Netherlands, and Norway. Information on outcome variables was collected using self-administered questionnaires at first clinical presentation. Compared with late-onset male-to-females, early-onset individuals tended to show sexual attraction toward males more frequently (50.5%), involve genitals less frequently in partner-related sexual activity, and consider penile sensations and orgasm as more negative. Early-onset female-to-males predominantly reported sexual attraction toward females (84.0%), whereas those with a late-onset more frequently showed other sexual attractions (41.7%). The study (a) shows that early- and late-onset male-to-females differ considerably with regard to coping strategies involving their body during sexual relations and (b) reveals initial insights into developmental pathways of late-onset female-to-males.

    Understanding public risk perceptions and their underlying processes is important in order to learn more about the way people interpret and respond to hazardous emergency events. Direct experience with an involuntary hazard has been found to heighten the perceived risk of experiencing the same hazard and its consequences in the future, but it remains unclear if cross-over effects are possible (i.e., experience with one hazard influencing perceived risk for other hazards also). Furthermore, the impact of objective risk and country of residence on perceived risk is not well understood. As part of the BeSeCu (Behavior, Security, and Culture) Project, a sample of 1,045 survivors of emergencies from seven European countries (i.e., Germany, the Czech Republic, Poland, Sweden, Spain, Turkey, and Italy) was drawn. Results revealed heightened perceived risk for emergency events (i.e., domestic and public fires, earthquakes, floods, and terrorist attacks) when the event had been experienced previously plus some evidence of cross-over effects, although these effects were not so strong. The largest country differences in perceived risk were observed for earthquakes, but this effect was significantly reduced by taking into account the objective earthquake risk. For fires, floods, terrorist attacks, and traffic accidents, only small country differences in perceived risk were found. Further studies including a larger number of countries are welcomed. © 2013 Society for Risk Analysis.

    Predicting ecosystem responses to global change has become a major challenge, particularly as terrestrial ecosystems contribute to the mitigation of global climate change through carbon sequestration. Plant traits are major surrogates of ecosystem physiology may thus help to predict carbon (C) fluxes and their consequences for the delivery of ecosystem services (e.g. C sequestration) across climatic gradients and in changing environments. However, linkages between community abundance-weighted means (CWM) of plant functional traits and ecosystem C fluxes have rarely been tested. It is also not known to what degree traits, which are typically measured at a defined point in time, are suitable for predicting annual C fluxes. We analysed the relationships between ecosystem fluxes and community level plant traits for 13 European grasslands under contrasting climate and management regimes, using multiyear eddy covariance data. Plant traits (specific leaf area SLA, leaf dry matter content LDMC, specific root length SLR) were determined at peak biomass. Analyses showed that GPPmax (at maximum radiation) was related to SLA, SRL and LDMC across sites and management, where GPPmax was an excellent indicator for annual GPP. Similar relations were found between for root density (and -diameter) and ecosystem respiration. Ecosystems respiration at GPPmax was also in line with annual respiration, indicating the strong predictive potential of plant community traits. Our study therefore suggests that above- and belowground community level plant traits are well suited surrogates for predicting ecosystem C fluxes at peak biomass and at annual scale.

  7. Implications of Switching Fossil Fuel Subsidies to Solar: A Case Study for the European Union

    Full Text Available Fossil fuel subsidies (FFS constitute one of the most obvious barriers to tackling climate change, as they encourage inefficient energy consumption and divert investment away from clean energy sources. According to the International Monetary Fund, FFS amounted globally to $233 billion in 2014, over four times the value of subsidies awarded to promote renewable energy. In this study an integrated assessment model is used to analyse the CO2 implications in the European Union of eliminating FFS and recycling the revenues to promote rooftop PV. It is found that eliminating FFS would give rise to a small reduction in CO2 due to fuel-switching from coal to gas. If the revenues were recycled to promote solar, then the CO2 reduction would increase from 1.8% to 2.2% by 2030. Eliminating FFS is not a panacea from the mitigation point of view, even if the revenues are recycled, but other important objectives, such as those related to renewable energy promotion and the reduction of air pollution, are advanced at zero cost for the government.

    Factors promoting family adaptation to child's disability are poorly studied together. The aim of the study was to describe the family adaptation to disability and to identify determinants associated with using a global theoretical model. 286 families of teenagers [13-17 years] with cerebral palsy (CP) from 4 European disability registers were included and visited at home. Face to face interviews were performed in order to measure parental distress, perceived impact in various dimensions of family life, family resources and stressors. Relationships were modelled with structural equations. 31.8% of parents living with an adolescent with CP showed clinically significant high stress requiring professional assistance. The main stressors were the level of motor impairment and behavioural disorders in adolescent. A good family functioning was the best protective factor. Respite in care and a parents' positive attitude were significantly related to less parental distress. Material support, socioeconomical level, marital status or parental qualifications did not appear to be significant protector factors. Particular attention must be paid not only on physical condition but also on adolescent psychological problems to improve family adaptation. Families at risk of experiencing severe distress should be targeted early and proactive caregiver interventions on the whole family should be performed. Family is a dynamic system: facing disability, it tries to recover its balance with available resources and its perception of the situation. Literature highlights potential stressors and protecting factors that could affect the disabled child's family adaptation but few papers study a global model including most of these factors. This study validated a global theoretical model of family adaptation to disability at adolescence. It identified behaviour disorders and motor impairment level as main stressors, family functioning as the largest protecting factors, and equipment and

    Full Text Available Abstract Background Systematic and reliable epidemiological information at population level, preferably cross-national, is needed for an adequate planning of (end-of-life health care policies, e.g. concerning place of death, but is currently lacking. This study illustrates opportunities and weaknesses of death certificate data to provide such information on place of death and associated factors in nine European countries (seven entire countries and five regions. Methods We investigated the possibility and modality of all partners in this international comparative study (BE, DK, IT, NL, NO, SE, UK to negotiate a dataset containing all deaths of one year with their national/regional administration of mortality statistics, and analysed the availability of information about place of death as well as a number of clinical, socio-demographic, residential and healthcare system factors. Results All countries negotiated a dataset, but rules, procedures, and cost price to get the data varied strongly between countries. In total, about 1.1 million deaths were included. For four of the nine countries not all desired categories for place of death were available. Most desired clinical and socio-demographic information was available, be it sometimes via linkages with other population databases. Healthcare system factors could be made available by linking existing healthcare statistics to the residence of the deceased. Conclusion Death certificate data provide information on place of death and on possibly associated factors and confounders in all studied countries. Hence, death certificate data provide a unique opportunity for cross-national studying and monitoring of place of death. However, modifications of certain aspects of death certificate registration and rules of data-protection are perhaps required to make international monitoring of place of death more feasible and accurate.

    In the Astrobiology context, the study of the physico-chemical interactions involving "building blocks of life" in plausible prebiotic and space-like conditions is fundamental to shed light on the processes that led to emergence of life on Earth as well as to molecular chemical evolution in space. In this PhD Thesis, such issues have been addressed both experimentally and computationally by employing vibrational spectroscopy, which has shown to be an effective tool to investigate the variety of intermolecular interactions that play a key role in self-assembling mechanisms of nucleic acid components and their binding to mineral surfaces. In particular, in order to dissect the contributions of the different interactions to the overall spectroscopic signals and shed light on the intricate experimental data, feasible computational protocols have been developed for the characterization of the spectroscopic properties of such complex systems. This study has been carried out through a multi-step strategy, starting the investigation from the spectroscopic properties of the isolated nucleobases, then studying the perturbation induced by the interaction with another molecule (molecular dimers), towards condensed phases like the molecular solid, up to the case of nucleic acid components adsorbed on minerals. A proper modeling of these weakly bound molecular systems has required, firstly, a validation of dispersion-corrected Density Functional Theory methods for simulating anharmonic vibrational properties. The isolated nucleobases and some of their dimers have been used as benchmark set for identifying a general, reliable and effective computational procedure based on fully anharmonic quantum mechanical computations of the vibrational wavenumbers and infrared intensities within the generalized second order vibrational perturbation theory (GVPT2) approach, combined with the cost-effective dispersion-corrected density functional B3LYP-D3, in conjunction with basis sets of

    Full Text Available Lung deep lymphatic drainage (LDLD plays an important role in the removal of foreign materials from lungs being alveolar macrophages the first line of phagocytic defence with high affinity for pathogenic microorganisms. Bacillus subtilis is a well-known genome- decoded saprophyte of the human respiratory tract used in research and in the biotechnology industry.Lung deep lymphatic chains (LDLC constitute one of the first sites of lung tumours’ dissemination. In this work we intended to develop and validate a non-invasive method for assessing LDLC by nanoradioliposomes aerosolised modulated on the Bacillus subtilis spore wall. The final goal was to produce a nanoradioliposome formulation that can mimics the dynamics of preferential removal of spores by LDLD and present the ideal properties as a tracer for molecular imaging studies.Seven different liposomal formulations were tested, and the formulation-F demonstrated physicochemical and radiopharmaceutical properties that make it an ideal candidate as an in vivo probe for molecular imaging studies of the LDLC.Nanoradioliposomes of the formulation-F after labelling with 99mTc-HMPAO were administered as aerosols to 20 Sus scrofa. Hilar and interpulmonary communications were visualized in first 5 minutes post-inhalation, infradiaphragmatic chains between 10 and 20 minutes, the ganglia of the aortic chain at 20 minutes and those of the renal hilar region at 30 minutes. Conclusion: the proposed method enables visualization of deep lymphatic lung network and lymph nodes. Besides, this technique involving the modulation of nanoradioliposomes targeting specific organs or tissues may be an important tool for diagnostic or even for therapeutic purposes. Resumo: A drenagem linfática pulmonar profunda (DLPP desempenha um papel importante na remoção de materiais estranhos, constituindo os macrófagos alveolares a primeira linha de defesa fagocitária, dada a grande afinidade para

  13. Cluster beam steering onto silicon surfaces studied by molecular dynamics

    Mazzone, A M

    2002-01-01

    The purpose of this study is to investigate the effects of the impact conditions on cluster deposition in silicon and is motivated by recent results obtained using a variable incidence angle during deposition of metallic clusters and atoms. Therefore deposition of silicon clusters with a kinetic energy in the range from 0.5 to 10 eV/atom directed at normal and grazing incidence onto crystalline silicon has been studied using a molecular dynamics simulation method. The influence of other relevant parameters, such as the interatomic forces and the cluster size and shape, has also been investigated. This study shows that the physics of deposition is almost entirely dictated by the nature of the interatomic forces. When using potentials with the four-fold coordination typical of bulk a clear dependence on the size N is observed and the spreading index eta decreases with the increase of N for all incidence conditions. The cluster binding strength is perceptibly increased when using a potential accounting for the c...

    Restless legs syndrome is a prevalent chronic neurological disorder with potentially severe mental and physical health consequences. Clearer understanding of the underlying pathophysiology is needed to improve treatment options. We did a meta-analysis of genome-wide association studies (GWASs) to identify potential molecular targets. In the discovery stage, we combined three GWAS datasets (EU-RLS GENE, INTERVAL, and 23andMe) with diagnosis data collected from 2003 to 2017, in face-to-face interviews or via questionnaires, and involving 15 126 cases and 95 725 controls of European ancestry. We identified common variants by fixed-effect inverse-variance meta-analysis. Significant genome-wide signals (p≤5 × 10 -8 ) were tested for replication in an independent GWAS of 30 770 cases and 286 913 controls, followed by a joint analysis of the discovery and replication stages. We did gene annotation, pathway, and gene-set-enrichment analyses and studied the genetic correlations between restless legs syndrome and traits of interest. We identified and replicated 13 new risk loci for restless legs syndrome and confirmed the previously identified six risk loci. MEIS1 was confirmed as the strongest genetic risk factor for restless legs syndrome (odds ratio 1·92, 95% CI 1·85-1·99). Gene prioritisation, enrichment, and genetic correlation analyses showed that identified pathways were related to neurodevelopment and highlighted genes linked to axon guidance (associated with SEMA6D), synapse formation (NTNG1), and neuronal specification (HOXB cluster family and MYT1). Identification of new candidate genes and associated pathways will inform future functional research. Advances in understanding of the molecular mechanisms that underlie restless legs syndrome could lead to new treatment options. We focused on common variants; thus, additional studies are needed to dissect the roles of rare and structural variations. Deutsche Forschungsgemeinschaft, Helmholtz Zentrum

    In 2004 the European Commission and Member States initiated activities towards a harmonized approach for Human Biomonitoring surveys throughout Europe. The main objective was to sustain environmental health policy by building a coherent and sustainable framework and by increasing the comparability of data across countries. A pilot study to test common guidelines for setting up surveys was considered a key step in this process. Through a bottom-up approach that included all stakeholders, a joint study protocol was elaborated. From September 2011 till February 2012, 17 European countries collected data from 1844 mother–child pairs in the frame of DEMOnstration of a study to COordinate and Perform Human Biomonitoring on a European Scale (DEMOCOPHES). Mercury in hair and urinary cadmium and cotinine were selected as biomarkers of exposure covered by sufficient analytical experience. Phthalate metabolites and Bisphenol A in urine were added to take into account increasing public and political awareness for emerging types of contaminants and to test less advanced markers/markers covered by less analytical experience. Extensive efforts towards chemo-analytical comparability were included. The pilot study showed that common approaches can be found in a context of considerable differences with respect to experience and expertize, socio-cultural background, economic situation and national priorities. It also evidenced that comparable Human Biomonitoring results can be obtained in such context. A European network was built, exchanging information, expertize and experiences, and providing training on all aspects of a survey. A key challenge was finding the right balance between a rigid structure allowing maximal comparability and a flexible approach increasing feasibility and capacity building. Next steps in European harmonization in Human Biomonitoring surveys include the establishment of a joint process for prioritization of substances to cover and biomarkers to develop

    PurposeThe purpose of the study was to investigate safety and feasibility of day-case endovascular procedures for the management of peripheral arterial disease.Materials and MethodsThis was a multi-center, retrospective study including all patients treated over a 30-month period with endovascular angioplasty or stenting for intermittent claudication (IC) or critical limb ischemia (CLI) on a day-case basis, in Interventional Radiology (IR) departments of three European tertiary hospitals. Exclusion criteria were not related to the type of lesion and included unavailability of an adult able to take care of patient overnight; high bleeding risk and ASA score ≥4. Primary efficacy outcome was the rate of procedures performed on an outpatient basis requiring no further hospitalization and primary safety outcome was freedom from 30-day major complications’ rate.ResultsThe study included 652 patients (male 75 %; mean age 68 ± 10 years; range: 27–93), 24.6 % treated for CLI. In 53.3 % of the cases a 6Fr sheath was used. Technical success was 97.1 %. Haemostasis was obtained by manual compression in 52.4 % of the accesses. The primary efficacy outcome occurred in 95.4 % (622/652 patients) and primary safety outcome in 98.6 % (643/652 patients). Major complications included five (0.7 %) retroperitoneal hematomas requiring transfusion; one (0.1 %) common femoral artery pseudoaneurysm successfully treated with US-guided thrombin injection, two cases of intra-procedural distal embolization treated with catheter-directed local thrombolysis and one on-table cardiac arrest necessitating >24 h recovery. No major complication was noted after same-day discharge.ConclusionsDay-case endovascular procedures for the treatment of IC or CLI can be safely and efficiently performed in experienced IR departments of large tertiary hospitals.

    Few studies have examined the mode of birth among women with fear of childbirth, and the results are conflicting. The objective of this study was to assess the association between fear of childbirth and cesarean delivery in North European women. A longitudinal cohort study was conducted among 6,422 pregnant women from Belgium, Iceland, Denmark, Estonia, Norway, and Sweden. Fear of childbirth was measured by the Wijma Delivery Expectancy Questionnaire during pregnancy and linked to obstetric information from hospital records. Among 3,189 primiparous women, those reporting severe fear of childbirth were more likely to give birth by elective cesarean, (OR, 1.66 [95% CI 1.05-2.61]). Among 3,233 multiparous women, severe fear of childbirth increased the risk of elective cesarean (OR 1.87 [95% CI 1.30-2.69]). Reporting lack of positive anticipation, one of six dimensions of fear of childbirth, was most strongly associated with elective cesarean (OR 2.02 [95% CI 1.52-2.68]). A dose-effect pattern was observed between level of fear and risk of emergency cesarean in both primiparous and multiparous women. Indications for cesarean were more likely to be reported as "nonmedical" among those with severe fear of childbirth; 16.7 versus 4.6 percent in primiparous women, and 31.7 versus 17.5 percent in multiparous women. Having severe fear of childbirth increases the risk of elective cesarean, especially among multiparous women. Lack of positive anticipation of the upcoming childbirth seems to be an important dimension of fear associated with cesarean delivery. Counseling for women who do not look forward to vaginal birth should be further evaluated. © 2015 Wiley Periodicals, Inc.

    To examine the association of health-related physical fitness components and accurate measures of fatness with attention in European adolescents. Cross-sectional study. A sub-sample of 444 adolescents from the HELENA study (14.5±1.2years) from 6 different countries participated in this study. Adolescents underwent evaluations of fitness (20m shuttle run, handgrip strength, standing long jump and 4×10m shuttle run tests), fatness (body mass index, skinfold thicknesses, bioelectrical impedance, Bod Pod and dual-energy X-ray absorptiometry) and attention (d2-test). Higher cardiorespiratory fitness was positively associated with better attention capacity (β=0.1, p=0.03). Body mass index and fat mass index measured by Bod Pod and dual-energy X-ray absorptiometry in a subset were negatively associated with attention (β=-0.11, p=0.02; β=-0.36, p=0.02; β=-0.34, p=0.03; respectively). All models were adjusted for age, sex, family-affluence scale and mother education. When these models were additionally adjusted for cardiorespiratory fitness when fatness was the main predictor and vice versa, the associations were somewhat attenuated and were no longer statistically significant. Muscular strength, speed-agility and body fatness markers measured by bioelectrical impedance and skinfolds were not associated with attention. The fit and non-overweight adolescents presented the highest values of attention capacity whilst their unfit and overweight peers showed the lowest values of attention (47.31±2.34 vs. 33.74±4.39; p<0.01). Our results support that both cardiorespiratory fitness and fatness are associated with attention, yet these associations are not independent. A combined effect was also observed, with fit and non-overweight adolescents showing the highest levels of attention and those unfit and overweight the lowest.

    In 2004 the European Commission and Member States initiated activities towards a harmonized approach for Human Biomonitoring surveys throughout Europe. The main objective was to sustain environmental health policy by building a coherent and sustainable framework and by increasing the comparability of data across countries. A pilot study to test common guidelines for setting up surveys was considered a key step in this process. Through a bottom-up approach that included all stakeholders, a joint study protocol was elaborated. From September 2011 till February 2012, 17 European countries collected data from 1844 mother-child pairs in the frame of DEMOnstration of a study to COordinate and Perform Human Biomonitoring on a European Scale (DEMOCOPHES).(1) Mercury in hair and urinary cadmium and cotinine were selected as biomarkers of exposure covered by sufficient analytical experience. Phthalate metabolites and Bisphenol A in urine were added to take into account increasing public and political awareness for emerging types of contaminants and to test less advanced markers/markers covered by less analytical experience. Extensive efforts towards chemo-analytical comparability were included. The pilot study showed that common approaches can be found in a context of considerable differences with respect to experience and expertize, socio-cultural background, economic situation and national priorities. It also evidenced that comparable Human Biomonitoring results can be obtained in such context. A European network was built, exchanging information, expertize and experiences, and providing training on all aspects of a survey. A key challenge was finding the right balance between a rigid structure allowing maximal comparability and a flexible approach increasing feasibility and capacity building. Next steps in European harmonization in Human Biomonitoring surveys include the establishment of a joint process for prioritization of substances to cover and biomarkers to develop
