    The authors compare the prevalence of challenges and opportunities in commentaries and descriptive accounts versus evaluative studies of social media use in medical education. A previously published report of social media use in medical education provided an in-depth discussion of 14 evaluative studies, a small subset of the total number of 99 articles on this topic. This study used the full set of articles identified by that review, including the 58 commentaries and 27 descriptive accounts which had not been previously reported, to provide a glimpse into how emerging tools in medical education are initially perceived. Each commentary, descriptive account, and evaluative study was identified and compared on various characteristics, including discussion themes regarding the challenges and opportunities of social media use in medical education. Themes related to the challenges of social media use in medical education were more prevalent in commentaries and descriptive accounts than in evaluative studies. The potential of social media to affect medical professionalism adversely was the most commonly discussed challenge in the commentaries (53%) and descriptive accounts (63%) in comparison to technical issues related to implementation in the evaluative studies (50%). Results suggest that the early body of literature on social media use in medical education-like that of previous innovative education tools-comprises primarily commentaries and descriptive accounts that focus more on the challenges of social media than on potential opportunities. These results place social media tools in historical context and lay the groundwork for expanding on this novel approach to medical education.

    Most cases of candidiasis have been attributed to Candida albicans, but Candida glabrata, Candida parapsilosis and Candida tropicalis, designated as non-C. albicans Candida (NCAC), have been identified as frequent human pathogens. Moreover, Candida biofilms are an escalating clinical problem associated with significant rates of mortality. Biofilms have distinct developmental phases, including adhesion/colonisation, maturation and dispersal, controlled by complex regulatory networks. This review discusses recent advances regarding Candida species biofilm regulatory network genes, which are key components for candidiasis. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Emergency departments are important safety nets for people who live in rural areas. Moreover, a serious problem in access to healthcare services has emerged in these regions. The challenges of providing access to quality rural emergency care include recruitment and retention issues, lack of advanced imagery technology, lack of specialist support and the heavy reliance on ambulance transport over great distances. The Quebec Ministry of Health and Social Services published a new version of the Emergency Department Management Guide, a document designed to improve the emergency department management and to humanise emergency department care and services. In particular, the Guide recommends solutions to problems that plague rural emergency departments. Unfortunately, no studies have evaluated the implementation of the proposed recommendations. To develop a comprehensive portrait of all rural emergency departments in Quebec, data will be gathered from databases at the Quebec Ministry of Health and Social Services, the Quebec Trauma Registry and from emergency departments and ambulance services managers. Statistics Canada data will be used to describe populations and rural regions. To evaluate the use of the 2006 Emergency Department Management Guide and the implementation of its various recommendations, an online survey and a phone interview will be administered to emergency department managers. Two online surveys will evaluate quality of work life among physicians and nurses working at rural emergency departments. Quality-of-care indicators will be collected from databases and patient medical files. Data will be analysed using statistical (descriptive and inferential) procedures. This protocol has been approved by the CSSS Alphonse-Desjardins research ethics committee (Project MP-HDL-1213-011). The results will be published in peer-reviewed scientific journals and presented at one or more scientific conferences.

    The availability of reliable biomarkers of aging is important not only to monitor the effect of interventions and predict the timing of pathologies associated with aging but also to understand the mechanisms and devise appropriate countermeasures. Blood cells provide an easily available tissue and gene expression profiles from whole blood samples appear to mirror disease states and some aspects of the aging process itself. We report here a microarray analysis of whole blood samples from two cohorts of healthy adult and elderly subjects, aged 43±3 and 68±4 years, respectively, to monitor gene expression changes in the initial phase of the senescence process. A number of significant changes were found in the elderly compared to the adult group, including decreased levels of transcripts coding for components of the mitochondrial respiratory chain, which correlate with a parallel decline in the maximum rate of oxygen consumption (VO2max), as monitored in the same subjects. In addition, blood cells show age-related changes in the expression of several markers of immunosenescence, inflammation and oxidative stress. These findings support the notion that the immune system has a major role in tissue homeostasis and repair, which appears to be impaired since early stages of the aging process.

    Most medical photographers, unless working as dedicated ophthalmic photographers or retinal screeners, will shoot portraits or publicity pictures. Many will spend a proportion of their time producing brochure shots for patient information material or their Trust's Annual Report. High-quality images of staff at work are often required by the strategic planning departments of Trusts to support bids for business from service commissioners. This "non-clinical" work is in reality commercial work - the jobs that high street portrait and general practice photographers would undertake in different settings. Medical photographers use many of the same tools as their commercial cousins. They use the same DSLR cameras and lenses. They use Adobe Photoshop to manipulate images. However, one software tool extensively used by portrait and social photographers, but possibly unfamiliar to many medical photographers, is Portrait Professional. Currently in its 10th version, it is produced by Anthropics Technology ( http://www.anthropics.com ), a London-based company specialising in image manipulation software.

    Chondrosarcoma is the second most frequent malignant bone tumor. However, the etiological background of chondrosarcomagenesis remains largely unknown, along with details on molecular alterations and potential therapeutic targets. Massively parallel paired-end sequencing of whole genomes of 10 primary chondrosarcomas revealed that the process of accumulation of somatic mutations is homogeneous irrespective of the pathological subtype or the presence of IDH1 mutations, is unique among a range of cancer types, and shares significant commonalities with that of prostate cancer. Clusters of structural alterations localized within a single chromosome were observed in four cases. Combined with targeted resequencing of additional cartilaginous tumor cohorts, we identified somatic alterations of the COL2A1 gene, which encodes an essential extracellular matrix protein in chondroskeletal development, in 19.3% of chondrosarcoma and 31.7% of enchondroma cases. Epigenetic regulators (IDH1 and YEATS2) and an activin/BMP signal component (ACVR2A) were recurrently altered. Furthermore, a novel FN1-ACVR2A fusion transcript was observed in both chondrosarcoma and osteochondromatosis cases. With the characteristic accumulative process of somatic changes as a background, molecular defects in chondrogenesis and aberrant epigenetic control are primarily causative of both benign and malignant cartilaginous tumors.

The opinion is that it was not painted later, over the original layer of the frescoes, but that it was made simultaneously with the other wall paintings of the lowest zones of the church. Considering the age of Stefan represented in the portrait composition, it is assumed that the decoration of the church was completed around 1385.

  1. Emerging use of gene expression microarrays in plant physiology.

    Wullschleger, Stan D; Difazio, Stephen P

    2003-01-01

    Microarrays have become an important technology for the global analysis of gene expression in humans, animals, plants, and microbes. Implemented in the context of a well-designed experiment, cDNA and oligonucleotide arrays can provide highthroughput, simultaneous analysis of transcript abundance for hundreds, if not thousands, of genes. However, despite widespread acceptance, the use of microarrays as a tool to better understand processes of interest to the plant physiologist is still being explored. To help illustrate current uses of microarrays in the plant sciences, several case studies that we believe demonstrate the emerging application of gene expression arrays in plant physiology were selected from among the many posters and presentations at the 2003 Plant and Animal Genome XI Conference. Based on this survey, microarrays are being used to assess gene expression in plants exposed to the experimental manipulation of air temperature, soil water content and aluminium concentration in the root zone. Analysis often includes characterizing transcript profiles for multiple post-treatment sampling periods and categorizing genes with common patterns of response using hierarchical clustering techniques. In addition, microarrays are also providing insights into developmental changes in gene expression associated with fibre and root elongation in cotton and maize, respectively. Technical and analytical limitations of microarrays are discussed and projects attempting to advance areas of microarray design and data analysis are highlighted. Finally, although much work remains, we conclude that microarrays are a valuable tool for the plant physiologist interested in the characterization and identification of individual genes and gene families with potential application in the fields of agriculture, horticulture and forestry.

    2015-02-01

    Lighting is a key factor in creating impressive artistic portraits. In this paper, we propose to analyze portrait lighting by learning templates of lighting styles. Inspired by the experience of artists, we first define several novel features that describe the local contrasts in various face regions. The most informative features are then selected with a stepwise feature pursuit algorithm to derive the templates of various lighting styles. After that, the matching scores that measure the similarity between a testing portrait and those templates are calculated for lighting style classification. Furthermore, we train a regression model by the subjective scores and the feature responses of a template to predict the score of a portrait lighting quality. Based on the templates, a novel face illumination descriptor is defined to measure the difference between two portrait lightings. Experimental results show that the learned templates can well describe the lighting styles, whereas the proposed approach can assess the lighting quality of artistic portraits as human being does.

It focuses on time and memory, including the experiential associations (in consciousness and the senses that the self engenders, thus linking the "visual" (photographic and "auto/biographical". The article attempts to "map" a field—the use of portraiture within social science—drawing on narrative and biographical research, on one side, and photographic portraiture, on the other. In supporting the use of photography in qualitative research it points to the need for researchers to have a greater knowledge of photographic (and art criticism and cognisance of photographic practices. The article does not intend to give a definitive account of photographic portraiture or prescribe in detail how it may be used within social science. It is an initial overview of the development and issues within the area of photographic portraiture and an exploration of relevant methodological issues when images of individuals are employed within social science—so that "portraiture" is better understood and developed within biographical and narrative research.

    Marie Curie was awarded the Nobel Prize in chemistry 1911. During the preceding year a rumour had circulated in Stockholm that she had had an affaire with one of her assistants. She received a letter, in which she was told that there had been strong opposition to her election not on scientific but moral grounds, and that she should not go to Stockholm, because nobody could forsee what reactions her appearance at the prize ceremony could evoke. Emil Kleen, a man of violent temper and radical opinions, reacted strongly to these rumours. He wrote a paper, with a violent attack on Gustaf Retzius, previous professor of Histology at Karolinska Institutet. Rightly or wrongly he suspected him to be the author of the infamous letter. Retzius is described as a dilletant in scientific matters, as a "sexual hyena" and a garroulus old man. This portrait of Retzius is of course most unfair, but the portrait of Emil Kleen by the famous swedish artist Bruno Liljefors is a masterpiece and one of the most valuable of the Swedish Medical Association.

Later I learned that Salk’s efforts were built on pioneering work of many others, including John Enders, Thomas Weller and Frederick Robbins (Nobelists, 1954), and David Bodian, who pioneered studies of polio pathogenesis and immunity. Bodian became my teacher in medical school, and Robbins became a colleague. Later, Salk, Robbins and I shared a platform at an infectious diseases symposium, and I was privileged to speak at Robbins’ retirement. But that gets ahead of my story.

  13. On the number of New World founders: a population genetic portrait of the peopling of the Americas.

    The founding of New World populations by Asian peoples is the focus of considerable archaeological and genetic research, and there persist important questions on when and how these events occurred. Genetic data offer great potential for the study of human population history, but there are significant challenges in discerning distinct demographic processes. A new method for the study of diverging populations was applied to questions on the founding and history of Amerind-speaking Native American populations. The model permits estimation of founding population sizes, changes in population size, time of population formation, and gene flow. Analyses of data from nine loci are consistent with the general portrait that has emerged from archaeological and other kinds of evidence. The estimated effective size of the founding population for the New World is fewer than 80 individuals, approximately 1% of the effective size of the estimated ancestral Asian population. By adding a splitting parameter to population divergence models it becomes possible to develop detailed portraits of human demographic history. Analyses of Asian and New World data support a model of a recent founding of the New World by a population of quite small effective size.

    Full Text Available One of the most important Macedonian artists from the first half of the twentieth century, Gorgi Zografski (1871-1945, spent a part of his life in Nis, painting icons and frescoes in this town and around it. He also worked in the area of Southern Serbia (Surdulica, Kursumlija. While he was living in Nis, he painted a few portraits, however, they disappeared without a trace. One of his pieces, made in 1910, was discovered in Aleksinac in the mid 2011. It is a group portrait of a merchant family. The painting shows a married couple, elegantly dresses with three children. The work I signed and dated. It is a formal, ceremonial portrait based on a photograph. Although the coloring is rather poor, the figure of the merchant is considered to be the best painted nail portrait in Gorgi Zografski's opus. The 'Portrait of the Members of a Merchant Family' is a piece of art found after the death of this artist. Gorgi lived, worked and created in the area of three Balkan countries (Macedonia, Bulgaria and Serbia. The portrait is seriously damaged at three places by bomb shrapnels during the bombardment of Nis on 4th, April, 1944. When it has been cleaned of dust and some restoration interventions been carried out, Macedonian art will certainly be one outstanding piece richer.

  3. The emerging pathogenic and therapeutic importance of the anaplastic lymphoma kinase gene.

    Kelleher, Fergal C

    2012-02-01

    The anaplastic lymphoma kinase gene (ALK) is a gene on chromosome 2p23 that has expression restricted to the brain, testis and small intestine but is not expressed in normal lymphoid tissue. It has similarity to the insulin receptor subfamily of kinases and is emerging as having increased pathologic and potential therapeutic importance in malignant disease. This gene was originally established as being implicated in the pathogenesis of rare diseases including inflammatory myofibroblastic tumour (IMT) and ALK-positive anaplastic large cell lymphoma, which is a subtype of non-Hodgkin\\'s lymphoma. Recently the number of diseases in which ALK is implicated in their pathogenesis has increased. In 2007, an inversion of chromosome 2 involving ALK and a fusion partner gene in a subset of non-small cell lung cancer was discovered. In 2008, publications emerged implicating ALK in familial and sporadic cases of neuroblastoma, a childhood cancer of the sympatho-adrenal system. Chromosomal abnormalities involving ALK are translocations, amplifications or mutations. Chromosomal translocations are the longest recognised ALK genetic abnormality. When translocations occur a fusion gene is created between ALK and a gene partner. This has been described in ALK-positive anaplastic large cell lymphoma in which ALK is fused to NPM (nucleolar protein gene) and in non-small cell lung cancer where ALK is fused to EML4 (Echinoderm microtubule-associated protein 4). The most frequently described partner genes in inflammatory myofibroblastic tumour are tropomyosin 3\\/4 (TMP3\\/4), however in IMTs a diversity of ALK fusion partners have been found, with the ability to homodimerise a common characteristic. Point mutations and amplification of the ALK gene occur in the childhood cancer neuroblastoma. Therapeutic targeting of ALK fusion genes using tyrosine kinase inhibition, vaccination using an ALK specific antigen and treatment using viral vectors for RNAi are emerging potential therapeutic

    Full Text Available Eli Heckscher was not only author of extensive investigations into economic history. He was also skillful in depicting phenomena in small format in encyclopædias, journals and newspapers. This article presents Heckscher as portrait maker of economic scholars. In these portraits—what he emphasized, what he praised, what he criticized—one can discern the stance of the portrait maker himself. Overall, his portraits are permeated by admiration of sharp theoretical analyses and massive economic historical investigations. He admires the founding fathers of political economy, Adam Smith and David Ricardo, stresses continuity in the development of economic thought, praises humble innovators like David Davidson, Knut Wicksell and Alfred Marshall and denounces (what he perceives as pretentious innovators like Gustav Cassel and John Maynard Keynes. He is critical towards economists who attempt to break out of the classical and neoclassical tradition, especially representatives of the German historical school, and what he judges to be a new type of mercantilism, represented by Bertil Ohlin and Keynes. At the same time he appreciates voluminous and solid investigations into economic history, even if performed without theoretical beacons, by scholars like William Cunningham, William Ashley, John Clapham, Marc Bloch, Richard Ehrenberg and Werner Sombart.

    Full Text Available Philosopher, feminist theoretician and artist Alenka Spacal paints her self-portraits on kitchen towels (2003–2005. After first being placed in exhibition, eventually the hanging of these pieces morphed into performance, dubbed Hanged Woman, during which the artist hung her self-portraits on a rope with clothespins in front of an audience. Transgressing gender, religion and race, Spacal through these self-portraits situates herself in different subjective positions. During such a journey, the artist multiplicates subjectivities, accomplishing theoretical and artistic figuration of nomadic subject, which, according to Rosi Braidotti constitutes by changing subject positions and thus overcoming dominant phallocentric rationality. In this case it occurs through artistic practice and irony. The second portion of this paper is devoted to the children’s picture book Rainbow Masquerade, also written and illustrated by Spacal, who abandons the essentialist dual normativity of sex and gender in order to represent plurality of the two categories in the fantastic world of a wood and its inhabitants.

  7. Phylostratigraphic tracking of cancer genes suggests a link to the emergence of multicellularity in metazoa

    Directory of Open Access Journals (Sweden)

    Domazet-Lošo Tomislav

    2010-05-01

    Full Text Available Abstract Background Phylostratigraphy is a method used to correlate the evolutionary origin of founder genes (that is, functional founder protein domains of gene families with particular macroevolutionary transitions. It is based on a model of genome evolution that suggests that the origin of complex phenotypic innovations will be accompanied by the emergence of such founder genes, the descendants of which can still be traced in extant organisms. The origin of multicellularity can be considered to be a macroevolutionary transition, for which new gene functions would have been required. Cancer should be tightly connected to multicellular life since it can be viewed as a malfunction of interaction between cells in a multicellular organism. A phylostratigraphic tracking of the origin of cancer genes should, therefore, also provide insights into the origin of multicellularity. Results We find two strong peaks of the emergence of cancer related protein domains, one at the time of the origin of the first cell and the other around the time of the evolution of the multicellular metazoan organisms. These peaks correlate with two major classes of cancer genes, the 'caretakers', which are involved in general functions that support genome stability and the 'gatekeepers', which are involved in cellular signalling and growth processes. Interestingly, this phylogenetic succession mirrors the ontogenetic succession of tumour progression, where mutations in caretakers are thought to precede mutations in gatekeepers. Conclusions A link between multicellularity and formation of cancer has often been predicted. However, this has not so far been explicitly tested. Although we find that a significant number of protein domains involved in cancer predate the origin of multicellularity, the second peak of cancer protein domain emergence is, indeed, connected to a phylogenetic level where multicellular animals have emerged. The fact that we can find a strong and

    Full Text Available If the artistic value of the Romanian medieval embroidery is obvious, it is no less real its documentary value. Most embroided portraits are made on liturgical pieces and they are a proof of the relationship of the rulers with the Orthodox Church. The position of the characters is a mute way of communicating the status that the voievod had. The vertical rigid representations, kneeling, the gestures of the palms and elbows, the beneficence objects, the way characters are grouped, the proportion or their placement in the work can be symbolically interpreted depending on the type of the Liturgical item on which the embroidery was done.

  12. An immunologic portrait of cancer

    Directory of Open Access Journals (Sweden)

    Stroncek David F

    2011-08-01

    Full Text Available Abstract The advent of high-throughput technology challenges the traditional histopathological classification of cancer, and proposes new taxonomies derived from global transcriptional patterns. Although most of these molecular re-classifications did not endure the test of time, they provided bulk of new information that can reframe our understanding of human cancer biology. Here, we focus on an immunologic interpretation of cancer that segregates oncogenic processes independent from their tissue derivation into at least two categories of which one bears the footprints of immune activation. Several observations describe a cancer phenotype where the expression of interferon stimulated genes and immune effector mechanisms reflect patterns commonly observed during the inflammatory response against pathogens, which leads to elimination of infected cells. As these signatures are observed in growing cancers, they are not sufficient to entirely clear the organism of neoplastic cells but they sustain, as in chronic infections, a self-perpetuating inflammatory process. Yet, several studies determined an association between this inflammatory status and a favorable natural history of the disease or a better responsiveness to cancer immune therapy. Moreover, these signatures overlap with those observed during immune-mediated cancer rejection and, more broadly, immune-mediated tissue-specific destruction in other immune pathologies. Thus, a discussion concerning this cancer phenotype is warranted as it remains unknown why it occurs in immune competent hosts. It also remains uncertain whether a genetically determined response of the host to its own cancer, the genetic makeup of the neoplastic process or a combination of both drives the inflammatory process. Here we reflect on commonalities and discrepancies among studies and on the genetic or somatic conditions that may cause this schism in cancer behavior.

    2017-01-01

    The Mexican artist Frida Kahlo (1907-1954) is one of the most celebrated artists of the 20th century. Although famous for her colorful self-portraits and associations with celebrities Diego Rivera and Leon Trotsky, less known is the fact that she had lifelong chronic pain. Frida Kahlo developed poliomyelitis at age 6 years, was in a horrific trolley car accident in her teens, and would eventually endure numerous failed spinal surgeries and, ultimately, limb amputation. She endured several physical, emotional, and psychological traumas in her lifetime, yet through her art, she was able to transcend a life of pain and disability. Of her work, her self-portraits are conspicuous in their capacity to convey her life experience, much of which was imbued with chronic pain. Signs and symptoms of chronic neuropathic pain and central sensitization of nociceptive pathways are evident when analyzing her paintings and medical history. This article uses a narrative approach to describe how events in the life of this artist contributed to her chronic pain. The purpose of this article is to discuss Frida Kahlo's medical history and her art from a modern pain sciences perspective, and perhaps to increase our understanding of the pain experience from the patient's perspective. © 2017 American Physical Therapy Association.

  14. The advantages and disadvantages of horizontal gene transfer and the emergence of the first species

    2011-01-01

    Full Text Available Abstract Background Horizontal Gene Transfer (HGT is beneficial to a cell if the acquired gene confers a useful function, but is detrimental if the gene has no function, if it is incompatible with existing genes, or if it is a selfishly replicating mobile element. If the balance of these effects is beneficial on average, we would expect cells to evolve high rates of acceptance of horizontally transferred genes, whereas if it is detrimental, cells should reduce the rate of HGT as far as possible. It has been proposed that the rate of HGT was very high in the early stages of prokaryotic evolution, and hence there were no separate lineages of organisms. Only when the HGT rate began to fall, would lineages begin to emerge with their own distinct sets of genes. Evolution would then become more tree-like. This phenomenon has been called the Darwinian Threshold. Results We study a model for genome evolution that incorporates both beneficial and detrimental effects of HGT. We show that if rate of gene loss during genome replication is high, as was probably the case in the earliest genomes before the time of the last universal common ancestor, then a high rate of HGT is favourable. HGT leads to the rapid spread of new genes and allows the build-up of larger, fitter genomes than could be achieved by purely vertical inheritance. In contrast, if the gene loss rate is lower, as in modern prokaryotes, then HGT is, on average, unfavourable. Conclusions Modern cells should therefore evolve to reduce HGT if they can, although the prevalence of independently replicating mobile elements and viruses may mean that cells cannot avoid HGT in practice. In the model, natural selection leads to gradual improvement of the replication accuracy and gradual decrease in the optimal rate of HGT. By clustering genomes based on gene content, we show that there are no separate lineages of organisms when the rate of HGT is high; however, as the rate of HGT decreases, a tree

    2018-04-01

    Full Text Available The ubiquitous mold Scedosporium apiospermum is increasingly recognized as an emerging pathogen, especially among patients with underlying disorders such as immunodeficiency or cystic fibrosis (CF. Indeed, it ranks the second among the filamentous fungi colonizing the respiratory tract of CF patients. However, our knowledge about virulence factors of this fungus is still limited. The role of iron-uptake systems may be critical for establishment of Scedosporium infections, notably in the iron-rich environment of the CF lung. Two main strategies are employed by fungi to efficiently acquire iron from their host or from their ecological niche: siderophore production and reductive iron assimilation (RIA systems. The aim of this study was to assess the existence of orthologous genes involved in iron metabolism in the recently sequenced genome of S. apiospermum. At first, a tBLASTn analysis using A. fumigatus iron-related proteins as query revealed orthologs of almost all relevant loci in the S. apiospermum genome. Whereas the genes putatively involved in RIA were randomly distributed, siderophore biosynthesis and transport genes were organized in two clusters, each containing a non-ribosomal peptide synthetase (NRPS whose orthologs in A. fumigatus have been described to catalyze hydroxamate siderophore synthesis. Nevertheless, comparative genomic analysis of siderophore-related clusters showed greater similarity between S. apiospermum and phylogenetically close molds than with Aspergillus species. The expression level of these genes was then evaluated by exposing conidia to iron starvation and iron excess. The expression of several orthologs of A. fumigatus genes involved in siderophore-based iron uptake or RIA was significantly induced during iron starvation, and conversely repressed in iron excess conditions. Altogether, these results indicate that S. apiospermum possesses the genetic information required for efficient and competitive iron uptake

    Older adults are increasingly likely to experience cohabitation, or living together unmarried in an intimate, heterosexual union. In order to begin building a conceptual framework, we provide a descriptive portrait of older adult cohabitors, emphasizing how they compare to older remarrieds and unpartnereds. We used data from both Census 2000 and the 1998 Health and Retirement Study ( HRS; Health and Retirement Study, 1998) to estimate the size and composition of the cohabiting population aged 51 and older. Also, using HRS data, we estimated multinomial logistic regression models to identify the correlates associated with cohabitation and remarriage (vs being unpartnered) among women and men who were previously married. More than 1 million older adults, composing 4% of the unmarried population, currently cohabit. About 90% of these individuals were previously married. We identify significant differences among cohabitors, remarrieds, and unpartnereds across several dimensions, including sociodemographic characteristics, economic resources, physical health, and social relationships. Cohabitors appear to be more disadvantaged than remarrieds, and this is especially evident for women. Older cohabitors differ from individuals of other marital statuses, and therefore future work on marital status should explicitly incorporate cohabitation.

    2009-09-01

    With increased attention on the visual in the history of science, there is renewed interest in the role of portraiture and other forms of personal imagery in constructing scientific reputation and the circulation of scientific ideas. This essay indicates some directions in which researchers could push forward by studying the dissemination of pictures and portraits of Charles Darwin. Selected portraits are discussed, with particular attention paid to their circulation. The mode of production and original intent of these portraits is briefly addressed, but the thrust of the argument is to highlight subsequent shifts in usage. While self-fashioning is an important part of the story, it is useful also to dwell on the rise and diversification of printed media in conjunction with escalating interest in Darwin as a celebrity figure. Historicizing the variety of opportunities that people have had of "looking"at Darwin adds considerably to our understanding of scientific fame.

  6. Emergent properties of gene evolution: Species as attractors in phenotypic space

    Reuveni, Eli; Giuliani, Alessandro

    2012-02-01

    The question how the observed discrete character of the phenotype emerges from a continuous genetic distance metrics is the core argument of two contrasted evolutionary theories: punctuated equilibrium (stable evolution scattered with saltations in the phenotype) and phyletic gradualism (smooth and linear evolution of the phenotype). Identifying phenotypic saltation on the molecular levels is critical to support the first model of evolution. We have used DNA sequences of ∼1300 genes from 6 isolated populations of the budding yeast Saccharomyces cerevisiae. We demonstrate that while the equivalent measure of the genetic distance show a continuum between lineage distance with no evidence of discrete states, the phenotypic space illustrates only two (discrete) possible states that can be associated with a saltation of the species phenotype. The fact that such saltation spans large fraction of the genome and follows by continuous genetic distance is a proof of the concept that the genotype-phenotype relation is not univocal and may have severe implication when looking for disease related genes and mutations. We used this finding with analogy to attractor-like dynamics and show that punctuated equilibrium could be explained in the framework of non-linear dynamics systems.

However, neuronal death induced by KA treatment was restricted to the injected hippocampus, although there was some contralateral axonal degeneration. We profiled gene expression changes in dorsal and ventral regions of both the injected...... and contralateral hippocampus. Changes were detected in the expression of 1526 transcripts in samples from three time-points: (i) during the KA-induced status epilepticus, (ii) at 2 weeks, before recurrent seizures emerged, and (iii) at 6 months after seizures emerged.

    In this paper, following the phase portraits analysis, we investigate the integrability of a system which physically describes the transverse oscillation of an elastic beam under end-thrust. As a result, we find that this system actually comprises two families of travelling waves: the sub- and super-sonic periodic waves of positive- and negative-definite velocities, respectively, and the localized sub-sonic loop-shaped waves of positive-definite velocity. Expressing the energy-like of this system while depicting its phase portrait dynamics, we show that these multivalued localized travelling waves appear as the boundary solutions to which the periodic travelling waves tend asymptotically.

    Full Text Available Abstract Background Solid tumors residing in tissues and organs leave footprints in circulation through circulating tumor cells (CTCs and circulating tumor DNAs (ctDNA. Characterization of the ctDNA portraits and comparison with tumor DNA mutational portraits may reveal clinically actionable information on solid tumors that is traditionally achieved through more invasive approaches. Methods We isolated ctDNAs from plasma of patients of 103 lung cancer and 74 other solid tumors of different tissue origins. Deep sequencing using the Guardant360 test was performed to identify mutations in 73 clinically actionable genes, and the results were associated with clinical characteristics of the patient. The mutation profiles of 37 lung cancer cases with paired ctDNA and tumor genomic DNA sequencing were used to evaluate clonal representation of tumor in circulation. Five lung cancer cases with longitudinal ctDNA sampling were monitored for cancer progression or response to treatments. Results Mutations in TP53, EGFR, and KRAS genes are most prevalent in our cohort. Mutation rates of ctDNA are similar in early (I and II and late stage (III and IV cancers. Mutation in DNA repair genes BRCA1, BRCA2, and ATM are found in 18.1% (32/177 of cases. Patients with higher mutation rates had significantly higher mortality rates. Lung cancer of never smokers exhibited significantly higher ctDNA mutation rates as well as higher EGFR and ERBB2 mutations than ever smokers. Comparative analysis of ctDNA and tumor DNA mutation data from the same patients showed that key driver mutations could be detected in plasma even when they were present at a minor clonal population in the tumor. Mutations of key genes found in the tumor tissue could remain in circulation even after frontline radiotherapy and chemotherapy suggesting these mutations represented resistance mechanisms. Longitudinal sampling of five lung cancer cases showed distinct changes in ctDNA mutation portraits that

    Full Text Available Notarial signs serving to authenticate private and public legal documents emerged in Dalmatia during the 12th century, and by the late Middle Ages they had become a mandatory part of official documents written on parchment for the legal parties. These signs were graphic as a rule: more or less elaborate drawings with decorative motifs, occasionally with integrated typography, yet without any figural elements. Among the very diverse forms of notarial signs preserved in Croatian archives, that of Split’s canon and Zadar’s notary Helias deserves special attention: instead of using a simple graphic symbol, he depicted a young man’s torso, which for several reasons may be presumed to be his self-portrait. More than fifty notarial signs by Helias have been preserved, but it may be presumed that he produced more than a thousand during more than two decades of his career as a notary. These signs are drawing of very small dimensions (3 x 1.5 cm on the average and most probably not a result of “artistic” ambition, presuming that such terminology applies at all to the visual production of the time. As many other literate men, Helias probably indulged in drawing and incorporated some of this inclination and skill into his work in a peculiar manner. Over the period of two decades, the depicted figure went through several transformations. Starting from a relatively realistic and quite detailed depiction, in the second phase Helias simplified the drawing and enhanced its elements of caricature, ending with a partially stylized and unified version of his sign. Generally speaking, his drawings were closer to the genre of caricature than an official visual representation, which is why he could style them rather freely as compared to the norms that could be observed in the professional circles, especially in the monumental painting of the 14th century. Despite the fact that they seem somehow timeless, their visual features indicate certain knowledge of

  13. Hemispheric asymmetries and gender influence Rembrandt's portrait orientations.

    2000-01-01

    For centuries painters have predominantly painted portraits with the model's left-cheek facing the viewer. This has been even more prevalent with females ( approximately 68%) than males ( approximately 56%). Numerous portraits painted by Rembrandt typify this unexplained phenomenon. In a preliminary experiment, subjects judged 24 emotional and social character traits in 20 portraits by Rembrandt. A factor analysis revealed that females with their left cheek exposed were judged to be much less socially appealing than less commonly painted right-cheeked females. Conversely, the more commonly painted right-cheeked males were judged to be more socially appealing than either left-cheeked males or females facing either direction. It is hypothesized that hemispheric asymmetries regulating emotional facial displays of approach and avoidance influenced the side of the face Rembrandt's models exposed due to prevailing social norms. A second experiment had different subjects judge a different collection of 20 portraits by Rembrandt and their mirror images. Mirror-reversed images produced the same pattern of results as their original orientation counterparts. Consequently, hemispheric asymmetries that specify the emotional expression on each side of the face are posited to account for the obtained results.

    Systematically distinguishing genetic liability from other contributing factors is critical for designing a preventive strategy for post-traumatic stress disorder (PTSD). To address this issue, we investigated a murine model exposing C57BL/6j, DBA/2j and BALB/cj mice to repeated stress via exposure to conspecific aggressors (Agg-E). Naïve mice from each strain were subjected to the proximity of aggressor (Agg) mice for 6h using a 'cage-within-a-cage' paradigm, which was repeated for 5 or 10 days with intermittent and unpredictable direct contact with Agg mice. During the Agg-E stress, DBA/2j developed a different strategy to evade Agg mice, which potentially contributed to its phenotypic resilience to Agg-E stress. Although Agg mice inflicted C57BL/6j and BALB/cj with equivalent numbers of strikes, BALB/cj displayed a distinct behavioral phenotype with delayed exhibition of a number of PTSD-like features. By contrast, C57BL/6j mice displayed unique vulnerability to Agg-E stress induced myocardopathy, possibly attributable to their particular susceptibility to hypoxia. A group of genes (Bdnf, Ngf, Zwint, Cckbr, Slc6a4, Fkbp5) linked to PTSD and synaptic plasticity were significantly altered in C57BL/6j and BALB/cj Agg-E mice. Contributions of Agg-E stress history and genotypic heterogeneity emerged as the key mediators of PTSD-like features. Linking genetic components to specific phenotypic and pathological features could have potential clinical implications. Copyright © 2015 Elsevier B.V. All rights reserved.

    This article explores the psychoanalytic significance of the self-portraits of Egon Schiele and Frida Kahlo. Both artists employed the self-portrait as a central means of artistic expression. Their fanatic and prolific focus on artistic self-representation exemplifies the manner in which they dealt creatively with narcissistic issues. The therapeutic function of the self-portrait as mirror is examined as well as the part it plays in self-consolidation and identity maintenance.

    Full Text Available During the second half of the XIXth century, Europe, the United States and Russia witnessed a blossoming interest in the use of photography in the anthropological field, its specific use was not very clear and defined yet; as a consequence, its heuristic methodologies, technical shooting modalities, stylistic elements and figurative conventions were not clear either. We range goes from anthropometric photography to an ethnographic and folkloric portrait painting signed at the same time by anthropologists and travellers, professional photographers looking for exotic subjects, amateur photographers and soldiers who encourage a figural medley characterised by scientific, commercial and artistic veins that slowly finds its definition in some of its prevailing features, in primis those of the portrait with pictorial origins, however continuously declined and reinterpreted in several ways. In this context Anthropology seeks some links with aesthetics.

    Full Text Available Abstract Background With over 20 million formalin-fixed, paraffin-embedded (FFPE tissue samples archived each year in the United States alone, archival tissues remain a vast and under-utilized resource in the genomic study of cancer. Technologies have recently been introduced for whole-transcriptome amplification and microarray analysis of degraded mRNA fragments from FFPE samples, and studies of these platforms have only recently begun to enter the published literature. Results The Emerging Technologies for Translational Bioinformatics symposium on gene expression profiling for archival tissues featured presentations of two large-scale FFPE expression profiling studies (each involving over 1,000 samples, overviews of several smaller studies, and representatives from three leading companies in the field (Illumina, Affymetrix, and NuGEN. The meeting highlighted challenges in the analysis of expression data from archival tissues and strategies being developed to overcome them. In particular, speakers reported higher rates of clinical sample failure (from 10% to 70% than are typical for fresh-frozen tissues, as well as more frequent probe failure for individual samples. The symposium program is available at http://www.hsph.harvard.edu/ffpe. Conclusions Multiple solutions now exist for whole-genome expression profiling of FFPE tissues, including both microarray- and sequencing-based platforms. Several studies have reported their successful application, but substantial challenges and risks still exist. Symposium speakers presented novel methodology for analysis of FFPE expression data and suggestions for improving data recovery and quality assessment in pre-analytical stages. Research presentations emphasized the need for careful study design, including the use of pilot studies, replication, and randomization of samples among batches, as well as careful attention to data quality control.

    Full Text Available Images of a sound. Portraits and Pictures of Jazz. Davide Sparti [trans. lise hogan] It has always been maintained that jazz reflects the social and urban changes of its times, but little attention has been given to the reversed statement, or rather, that twentieth-century culture reflects jazz, reacting and responding to its presence, and re-elaborating its sounds in visual (as well as textual and choreographic forms. This paper, inspired by an exhibition of jazz album covers, examines the interplay between jazz and the visual arts. Notwithstanding the significant link between image and sound at the referential level of the content (album covers represent a mirror of the era and of its political changes, it is primarily the relationship established through the notion of process, action or operation that is crucial. We live in a videocentric age that greatly emphasizes the defined and completed object, and that has sanctioned the existence of a place for its worship: the museum. But an (improvised performance is above all an action, the action of generating music during the course of a performance. By focusing on the final product of a performance, we risk losing sight of the “phenomenon”: the emergence, sound after sound, of a musical sense. For many painters, precisely because they can take their time deciding what to “express”, the process recedes to the background and what becomes relevant (also for the evaluation of the artwork is what they produce. Yet, dating from the Surrealists and from Pollock, many visual arts exhibitors have been inspired by jazz and have placed the notion of process at the centre of their artistic practice.

  15. PORTRAIT IN LITERATURE AND GRAPHIC ART: THE CASE OF THE FIERY ANGEL

    Natalia A. Drovaleva

    2017-06-01

    Full Text Available This essay analyzes portraits in several editions of The Fiery Angel published during This essay analyzes portraits in several editions of The Fiery Angel published during Bryusov’s lifetime and claims that the portrait was as a universal point of convergence for verbal and visual arts. The dialogue between literature and graphics in the context of the synthesis of arts sheds new light on the possibilities for interdisciplinary research. The time of the “beautiful book” was a time of great artists and illustrators who introduced the peculiarities of their own style and the manner of their artistic schools into their art. Books were commonly decorated with vignettes and famous paintings. Portraits, as well as plates in general, were of the highest quality. They were ornamental and illusory, with every minute detail finely drawn out. Yet, in the second edition of the novel Bryusov deliberately included medieval engravings and portraits. A comparative analysis of the verbal portraits in The Fiery Angel and engraved portraits in the book (Ruprecht, Heinrich, Faust, Mephistopheles, Renata, and Madiel demonstrates that both the main and the secondary characters of the novel are picturesque and multidimensional whereas the xylographic portraits rather reveal conventionality and simplicity of the medieval time. This way Bryusov was seeking to debase clichе’s, especially as regards Agrippa von Nettesheim and Faust: according to Bryusov, the character of Agrippa had already become a clichе’d image and so was the popular engraving of the scientist that he reproduced in the middle of the sixth chapter of the 1909 edition. Juxtaposing the verbal and the graphic portraits in The Fiery Angel helps us better understand the function of the verbal portrait in a Symbolist text that was determined by the author’s design, on the one hand, and by various “instruments” of different arts, on the other.

    Full Text Available Nicotinamide Adenine Dinucleotide (NAD levels are essential for cellular homeostasis and survival. Main sources of intracellular NAD are the salvage pathways from nicotinamide, where Nicotinamide phosphoribosyltransferases (NAMPTs and Nicotinamidases (PNCs have a key role. NAMPTs and PNCs are important in aging, infection and disease conditions such as diabetes and cancer. These enzymes have been considered redundant since either one or the other exists in each individual genome. The co-occurrence of NAMPT and PNC was only recently detected in invertebrates though no structural or functional characterization exists for them. Here, using expression and evolutionary analysis combined with homology modeling and protein-ligand docking, we show that both genes are expressed simultaneously in key species of major invertebrate branches and emphasize sequence and structural conservation patterns in metazoan NAMPT and PNC homologues. The results anticipate that NAMPTs and PNCs are simultaneously active, raising the possibility that NAD salvage pathways are not redundant as both are maintained to fulfill the requirement for NAD production in some species.

    Directory of Open Access Journals (Sweden)

    Konstantin B Zeldovich

    2007-07-01

    Full Text Available In this work we develop a microscopic physical model of early evolution where phenotype--organism life expectancy--is directly related to genotype--the stability of its proteins in their native conformations-which can be determined exactly in the model. Simulating the model on a computer, we consistently observe the "Big Bang" scenario whereby exponential population growth ensues as soon as favorable sequence-structure combinations (precursors of stable proteins are discovered. Upon that, random diversity of the structural space abruptly collapses into a small set of preferred proteins. We observe that protein folds remain stable and abundant in the population at timescales much greater than mutation or organism lifetime, and the distribution of the lifetimes of dominant folds in a population approximately follows a power law. The separation of evolutionary timescales between discovery of new folds and generation of new sequences gives rise to emergence of protein families and superfamilies whose sizes are power-law distributed, closely matching the same distributions for real proteins. On the population level we observe emergence of species--subpopulations that carry similar genomes. Further, we present a simple theory that relates stability of evolving proteins to the sizes of emerging genomes. Together, these results provide a microscopic first-principles picture of how first-gene families developed in the course of early evolution.

This raises questions regarding the emotional significance of such biased positions. I presented rightward and leftward facing male and female portraits. I measured observers’ pupil size while asking observers to report how (displeasing they found each image. This was a methodological improvement over the type of research initially done by Eckhard Hess who claimed that pupils dilate to pleasant images and constrict to unpleasant images. His work was confounded since his images’ luminances and contrasts across conditions were inconsistent potentially affecting pupil size. To overcome this limitation I presented rightward or leftward facing male and female portraits by Rembrandt to observers in either their original or mirror-reversed position. I found that in viewing male portraits pupil diameter was a function of arousal. That is, larger pupil diameter occurred for images rated both low and high in pleasantness. This was not the case with female portraits. I discuss these findings in regard to the perceived dominance of males and how emotional expressions may be driven by hemispheric laterality.

  1. Strategy Escalation: An emerging paradigm for safe clinical development of T cell gene therapies

    Full Text Available Abstract Gene therapy techniques are being applied to modify T cells with chimeric antigen receptors (CARs for therapeutic ends. The versatility of this platform has spawned multiple options for their application with new permutations in strategies continually being invented, a testimony to the creative energies of many investigators. The field is rapidly expanding with immense potential for impact against diverse cancers. But this rapid expansion, like the Big Bang, comes with a somewhat chaotic evolution of its therapeutic universe that can also be dangerous, as seen by recently publicized deaths. Time-honored methods for new drug testing embodied in Dose Escalation that were suitable for traditional inert agents are now inadequate for these novel "living drugs". In the following, I propose an approach to escalating risk for patient exposures with these new immuno-gene therapy agents, termed Strategy Escalation, that accounts for the molecular and biological features of the modified cells and the methods of their administration. This proposal is offered not as a prescriptive but as a discussion framework that investigators may wish to consider in configuring their intended clinical applications.

However, a temporary increase in VIM-4-producing, clonally unrelated Enterobacteriaceae strains was described earlier in a Kuwaiti hospital. We investigated the genetic support of blaVIM-4 in six Klebsiella pneumoniae strains, one Escherichia coli, and one Enterobacter cloacae strain and compared it to that of VIM-4-producing isolates from other countries of the region. Five K. pneumoniae strains and the E. coli strain from Kuwait carried an ~165 kb IncA/C-type plasmid indistinguishable by restriction fragment length polymorphism. The complete sequence of one of them (pKKp4-VIM was established. pKKp4-VIM exhibited extensive similarities to episomes pKP-Gr642 carrying blaVIM-19 encountered in Greece and to the partially sequenced pCC416 harboring blaVIM-4 detected in Italy. In other countries of the region, the only similar plasmid was the one detected in the isolate from the UAE. In all Kuwaiti strains, irrespective of the species and their VIM plasmids, the blaVIM-4 gene was located within the same integron structure (In416, different from those of other countries of the region. Our data show that the spread of this IncA/C plasmid and particularly that of the In416 integron caused a considerable, albeit temporary, increase in the rate of mostly clonally unrelated VIM-producing Enterobacteriaceae strains of multiple species

    The canine parvovirus (CPV) infection is a highly contagious and serious enteric disease of dogs with high fatality rate. The present study was taken up to characterize the full-length viral polypeptide 2 (VP2) gene of CPV of Indian origin along with the commercially available vaccines. The faecal samples from parvovirus suspected dogs were collected from various states of India for screening by PCR assay and 66.29% of samples were found positive. Six CPV-2a, three CPV-2b, and one CPV-2c types were identified by sequence analysis. Several unique and existing mutations have been noticed in CPV types analyzed indicating emergence of newer variants of CPV in India. The phylogenetic analysis revealed that all the field CPV types were grouped in different subclades within two main clades, but away from the commercial vaccine strains. CPV-2b and CPV-2c types with unique mutations were found to be establishing in India apart from the prevailing CPV-2a type. Mutations and the positive selection of the mutants were found to be the major mechanism of emergence and evolution of parvovirus. Therefore, the incorporation of local strain in the vaccine formulation may be considered for effective control of CPV infections in India.

    While there is an ongoing trend to identify single nucleotide substitutions (SNSs) that are linked to inter/intra-species differences and disease phenotypes, short tandem repeats (STRs)/microsatellites may be of equal (if not more) importance in the above processes. Genes that contain STRs in their promoters have higher expression divergence compared to genes with fixed or no STRs in the gene promoters. In line with the above, recent reports indicate a role of repetitive sequences in the rise of young transcription start sites (TSSs) in human evolution. Following a comparative genomics study of all human protein-coding genes annotated in the GeneCards database, here we provide a genome-scale portrait of human-specific short- and medium-size (≥ 3-repeats) tri- and tetranucleotide STRs and STR motifs in the critical core promoter region between - 120 and + 1 to the TSS and evidence of skewing of this compartment in reference to the STRs that are not human-specific (Levene's test p human-specific transcripts was detected in the tri and tetra human-specific compartments (mid-p genome-scale skewing of STRs at a specific region of the human genome and a link between a number of these STRs and TSS selection/transcript specificity. The STRs and genes listed here may have a role in the evolution and development of characteristics and phenotypes that are unique to the human species.

    Dating in later life is likely common, especially as the proportion of older adults who are single continues to rise. Yet there are no recent national estimates of either the prevalence or factors associated with dating during older adulthood. Using data from the 2005-2006 National Social Life, Health, and Aging Project, a nationally representative sample of 3,005 individuals ages 57-85, the authors constructed a national portrait of older adult daters. Roughly 14% of singles were in a dating relationship. Dating was more common among men than women and declined with age. Compared to non-daters, daters were more socially advantaged. Daters were more likely to be college educated and had more assets, were in better health, and reported more social connectedness. This study underscores the importance of new research on partnering in later life, particularly with the aging of the U.S. population and the swelling ranks of older singles. PMID:24319296

Their main concern was to confirm Sava’s personal charisma and to convey a sense of his saintly authority. The focus of the paper is on the hagiographical techniques of imitation such as comparing the hero to biblical models and telling stories of his miracles that repeat the miracles of Christ himself and the most important saints. The paper devotes particular attention to those sections of the vitae that describe Sava’s wielding institutional authority, and it is precisely here that there are notable similarities between Teodosije’s vita and his hagiographical model, the vita of St. Sava of Jerusalem by Cyril of Skythopolis.

    Full Text Available Guided by the Christian faith, Byzantine art has attached special meaning to the representation of the human figure. Grounded on aesthetic principles, the artistic representation of the human face relinquished on the physical materiality of the represented model, searching for its essences and resemblances to the divine world. Subject to specific representation rules, Byzantine portraiture bears a series of peculiar characteristics that mark it out among other images of this kind belonging to other spirituality areas, periods and artistic styles. Both in icons, where it highlights a series of particular significances describing the divine nature of saints, and in other fields of Byzantine arts – such as mural painting or mosaic –the portrait stands out due to its importance. This paper intends to present a few of the defining characteristics of portraiture in Byzantine art, exemplifying the evolution of this artistic genre by analysing some of the most representative creations of this field.

  8. The Absent Painter: Ideological Premises in Tacitus portraits

    Juan Luis Conde

    2015-09-01

    Full Text Available An interpretation of René Magritte's series La condition humaine underlines its anti-realistic warning. On that analogical basis, an approach to three of Cornelius Tacitus' protraits of emperors is provided, namely those of Galba, Tiberius, and Augustus. A common feature in these personalities is their particular difficulty to be represented in the static and univocal way required by literary portrait. The paper analyzes the rhetorical and ideological devices used by the artist to tackle that goal. As a counterpart, a circularity in the appropriation of ideological legacies is suggested, according to which forms that were designed by writers to describe characters in their works have historically moulded social representations of personality

    Full Text Available OBJECTIVES The aim of our study is to determine the mental state of the arsonists that have undergone forensic psychiatric evaluation. MATERIALS AND METHODS We have examined the mental health records between years 2014-2015. Only subjects who committed fire setting crimes and were referred to the Legal Medicine Institute from Timișoara for a psychiatric evaluation were selected for the study. We analysed the following data: socio-demographic parameters, psychiatric diagnosis, motivation for the perpetrated crime, alcohol and drug addiction, the applied safety measure, the administrated neuroleptic and complementary treatment and the social support network. RESULTS The portrait of the arsonist is mainly male, young, single, poorly educated, unskilled and unemployed, living mostly in rural areas and with alcohol or drugs additction at the time of comitting the fire setting. Regarding the mental state of the patient, the most common diagnoses among the subjects were: psychoses, toxic substance delusional disorder, mixed personality disorder and intellectual disabilities. In most cases, arsonists lost discerment at the time of comitting the criminal act and they were not held accountable for it. CONCLUSIONS Our study established the most common psychiatric disturbances of arsonists as seen by forensic psychiatric examination. Different reasons for setting up fire have also been discussed. Patients were both delusional and irritated. We attempted to sketch a "portrait" of the arsonist and suggestions were included in order to ensure further "profiling" information gathering.

    We use dynamical system methods to explore the general behaviour of f(T) cosmology. In contrast to the standard applications of dynamical analysis, we present a way to transform the equations into a one-dimensional autonomous system, taking advantage of the crucial property that the torsion scalar in flat FRW geometry is just a function of the Hubble function, thus the field equations include only up to first derivatives of it, and therefore in a general f(T) cosmological scenario every quantity is expressed only in terms of the Hubble function. The great advantage is that for one-dimensional systems it is easy to construct the phase space portraits, and thus extract information and explore in detail the features and possible behaviours of f(T) cosmology. We utilize the phase space portraits and we show that f(T) cosmology can describe the universe evolution in agreement with observations, namely starting from a Big Bang singularity, evolving into the subsequent thermal history and the matter domination, entering into a late-time accelerated expansion, and resulting to the de Sitter phase in the far future. Nevertheless, f(T) cosmology can present a rich class of more exotic behaviours, such as the cosmological bounce and turnaround, the phantom-divide crossing, the Big Brake and the Big Crunch, and it may exhibit various singularities, including the non-harmful ones of type II and type IV. We study the phase space of three specific viable f(T) models offering a complete picture. Moreover, we present a new model of f(T) gravity that can lead to a universe in agreement with observations, free of perturbative instabilities, and applying the Om(z) diagnostic test we confirm that it is in agreement with the combination of SNIa, BAO and CMB data at 1σ confidence level.

  14. The Imaginary Self-portrait in the Poem Roman de la Rose

    Full Text Available “Every portrait that is painted with feeling is a portrait of the artist, not of the sitter…It is not he who is revealed by the painter; it is rather the painter who, on the coloured canvas, reveals himself,” explains the painter who created the evolving portrait of Dorian Gray. Guillaume de Lorris, the author of the medieval poem Roman de la Rose, also presents his soul through the character of the ideal lover, so Amans is a kind of self-portrait. But unlike an ordinary self-portrait, this one does not present the author’s personality. It is painted with words, and such an ekphrastic image is universal or influences the reader in ways that can be explained by the Iser’s reader-response theory. The poem enables the reader to feel love, and transforms him into the ideal courtly lover. As distinct from a painting, the invisible ekphrastic image in this text surpasses appearances and presents the reader with a hidden side of his soul. The object represented by ekphrasis does not exist in the outer world, therefore in the example examined here the reader’s other self is brought into existence. In contrast to a painted self-portrait, which represents the identity of the author, since the picture and the pictured are identical, a word is a sign which refers to something else. A verbal self-portrait which expresses the author’s feelings opens itself up to the reader, who has to complete the image with his imagination. This imaginary image then differs from the external appearance, because it reveals the associated feelings, enables the reader to feel what the author feels, and presents the reader with his other self. The imaginary self-portrait thus does not represent the actual self, but the self that is transformed or improved by the art of love.

    Full Text Available In the reign of Ferdinand I of Habsburg, important examples of portrait painting were done in the Lands of the Bohemian Crown. Though few examples of Renaissance portraiture of that period have survived, there are some noteworthy portraits dating from 1526–1564. The paper focuses on the reception of the so-called Habsburg portrait type in portrait painting in Bohemia and Moravia and examines the purpose for which the commissioners used it. Two specific approaches will be illustrated on the portrait cycle of Adam I of Hradec and his family, painted by Jacob Seisenegger and dated 1529, and portraits of William of Rosenberg, his brother and sisters, commissioned between 1552 and 1554. In both cases, the commissioners were persons of the highest rank in Bohemian aristocratic society

    Full Text Available Abstract Background Biological processes are mediated by networks of interacting genes and proteins. Efforts to map and understand these networks are resulting in the proliferation of interaction data derived from both experimental and computational techniques for a number of organisms. The volume of this data combined with the variety of specific forms it can take has created a need for comprehensive databases that include all of the available data sets, and for exploration tools to facilitate data integration and analysis. One powerful paradigm for the navigation and analysis of interaction data is an interaction graph or map that represents proteins or genes as nodes linked by interactions. Several programs have been developed for graphical representation and analysis of interaction data, yet there remains a need for alternative programs that can provide casual users with rapid easy access to many existing and emerging data sets. Description Here we describe a comprehensive database of Drosophila gene and protein interactions collected from a variety of sources, including low and high throughput screens, genetic interactions, and computational predictions. We also present a program for exploring multiple interaction data sets and for combining data from different sources. The program, referred to as the Interaction Map (IM Browser, is a web-based application for searching and visualizing interaction data stored in a relational database system. Use of the application requires no downloads and minimal user configuration or training, thereby enabling rapid initial access to interaction data. IM Browser was designed to readily accommodate and integrate new types of interaction data as it becomes available. Moreover, all information associated with interaction measurements or predictions and the genes or proteins involved are accessible to the user. This allows combined searches and analyses based on either common or technique-specific attributes

    Wastewater effluents increase the nutrient load of receiving streams while introducing a myriad of anthropogenic chemical pollutants that challenge the resident aquatic (micro)biota. Disentangling the effects of both kind of stressors and their potential interaction on the dissemination of antibiotic resistance genes in bacterial communities requires highly controlled manipulative experiments. In this work, we investigated the effects of a combined regime of nutrients (at low, medium and high concentrations) and a mixture of emerging contaminants (ciprofloxacin, erythromycin, sulfamethoxazole, diclofenac, and methylparaben) on the bacterial composition, abundance and antibiotic resistance profile of biofilms grown in artificial streams. In particular, we investigated the effect of this combined stress on genes encoding resistance to ciprofloxacin (qnrS), erythromycin (ermB), sulfamethoxazole (sul1 and sul2) as well as the class 1 integron-integrase gene (intI1). Only genes conferring resistance to sulfonamides (sul1 and sul2) and intI1 gene were detected in all treatments during the study period. Besides, bacterial communities exposed to emerging contaminants showed higher copy numbers of sul1 and intI1 genes than those not exposed, whereas nutrient amendments did not affect their abundance. However, bacterial communities exposed to both emerging contaminants and a high nutrient concentration (1, 25 and 1 mg L -1 of phosphate, nitrate and ammonium, respectively) showed the highest increase on the abundance of sul1 and intI1 genes thus suggesting a factors synergistic effect of both stressors. Since none of the treatments caused a significant change on the composition of bacterial communities, the enrichment of sul1 and intI1 genes within the community was caused by their dissemination under the combined pressure exerted by nutrients and emerging contaminants. To the best of our knowledge, this is the first study demonstrating the contribution of nutrients on

    Full Text Available Tumor necrosis factor-stimulated gene-6 (TSG-6 is a 35-kDa glycoprotein that has been shown to exert anti-inflammatory effects in experimental models of arthritis, acute myocardial infarction, and acute cerebral infarction. Several lines of evidence have shed light on the pathophysiological roles of TSG-6 in atherosclerosis. TSG-6 suppresses inflammatory responses of endothelial cells, neutrophils, and macrophages as well as macrophage foam cell formation and vascular smooth muscle cell (VSMC migration and proliferation. Exogenous TSG-6 infusion and endogenous TSG-6 attenuation with a neutralizing antibody for four weeks retards and accelerates, respectively, the development of aortic atherosclerotic lesions in ApoE-deficient mice. TSG-6 also decreases the macrophage/VSMC ratio (a marker of plaque instability and promotes collagen fibers in atheromatous plaques. In patients with coronary artery disease (CAD, plasma TSG-6 levels are increased and TSG-6 is abundantly expressed in the fibrous cap within coronary atheromatous plaques, indicating that TSG-6 increases to counteract the progression of atherosclerosis and stabilize the plaque. These findings indicate that endogenous TSG-6 enhancement and exogenous TSG-6 replacement treatments are expected to emerge as new lines of therapy against atherosclerosis and related CAD. Therefore, this review provides support for the clinical utility of TSG-6 in the diagnosis and treatment of atherosclerotic cardiovascular diseases.

    An association has been found between receipt of harsh parenting in childhood and adult health problems. However, this research has been principally retrospective, has treated children as passive recipients of parental behavior, and has overlooked individual differences in youth responsivity to harsh parenting. In a 10-year multiple-wave prospective study of African American families, we addressed these issues by focusing on the influence of polymorphisms in the oxytocin receptor gene (OXTR), variants of which appear to buffer or amplify responses to environmental stress. The participants were 303 youths, with a mean age of 11.2 at the first assessment, and their parents, all of whom were genotyped for variations in the rs53576 (A/G) polymorphism. Teachers rated preadolescent (ages 11 to 13) emotionally intense and distractible temperaments, and adolescents (ages 15 and 16) reported receipt of harsh parenting. Allostatic load was assessed during young adulthood (ages 20 and 21). Difficult preadolescent temperament forecast elevated receipt of harsh parenting in adolescence, and adolescents who experienced harsh parenting evinced high allostatic load during young adulthood. However, these associations emerged only among children and parents who carried A alleles of the OXTR genotype. The results suggest the oxytocin system operates along with temperament and parenting to forecast young adults' allostatic load.

    Seed germination is important to soybean (Glycine max) growth and development, ultimately affecting soybean yield. A lower seed field emergence has been the main hindrance for breeding soybeans low in phytate. Although this reduction could be overcome by additional breeding and selection, the mechanisms of seed germination in different low phytate mutants remain unknown. In this study, we performed a comparative transcript analysis of two low phytate soybean mutants (TW-1 and TW-1-M), which have the same mutation, a 2 bp deletion in GmMIPS1, but show a significant difference in seed field emergence, TW-1-M was higher than that of TW-1 . Numerous genes analyzed by RNA-Seq showed markedly different expression levels between TW-1-M and TW-1 mutants. Approximately 30,000-35,000 read-mapped genes and ~21000-25000 expressed genes were identified for each library. There were ~3900-9200 differentially expressed genes (DEGs) in each contrast library, the number of up-regulated genes was similar with down-regulated genes in the mutant TW-1and TW-1-M. Gene ontology functional categories of DEGs indicated that the ethylene-mediated signaling pathway, the abscisic acid-mediated signaling pathway, response to hormone, ethylene biosynthetic process, ethylene metabolic process, regulation of hormone levels, and oxidation-reduction process, regulation of flavonoid biosynthetic process and regulation of abscisic acid-activated signaling pathway had high correlations with seed germination. In total, 2457 DEGs involved in the above functional categories were identified. Twenty-two genes with 20 biological functions were the most highly up/down- regulated (absolute value Log2FC >5) in the high field emergence mutant TW-1-M and were related to metabolic or signaling pathways. Fifty-seven genes with 36 biological functions had the greatest expression abundance (FRPM >100) in germination-related pathways. Seed germination in the soybean low phytate mutants is a very complex process

    Ribosomal RNAs (rRNAs) account for >60% of all RNAs in eukaryotic cells and are encoded in the ribosomal DNA (rDNA) arrays. The rRNAs are produced from two sets of loci: the 5S rDNA array resides exclusively on human chromosome 1, whereas the 45S rDNA array resides on the short arm of five human acrocentric chromosomes. The 45S rDNA gives origin to the nucleolus, the nuclear organelle that is the site of ribosome biogenesis. Intriguingly, 5S and 45S rDNA arrays exhibit correlated copy number variation in lymphoblastoid cells (LCLs). Here we examined the genomic architecture and repeat content of the 5S and 45S rDNA arrays in multiple human genome assemblies (including PacBio MHAP assembly) and ascertained contacts between the rDNA arrays and the rest of the genome using Hi-C datasets from two human cell lines (erythroleukemia K562 and lymphoblastoid cells). Our analyses revealed that 5S and 45S arrays each have thousands of contacts in the folded genome, with rDNA-associated regions and genes dispersed across all chromosomes. The rDNA contact map displayed conserved and disparate features between two cell lines, and pointed to specific chromosomes, genomic regions, and genes with evidence of spatial proximity to the rDNA arrays; the data also showed a lack of direct physical interaction between the 5S and 45S rDNA arrays. Finally, the analysis identified an intriguing organization in the 5S array with Alu and 5S elements adjacent to one another and organized in opposite orientation along the array. Portraits of genome folding centered on the ribosomal DNA array could help understand the emergence of concerted variation, the control of 5S and 45S expression, as well as provide insights into an organelle that contributes to the spatial localization of human chromosomes during interphase. © The Author(s) 2016.

    Gustav Klimt was an Austrian Symbolist painter and one of the most important representatives of the modernist movement of the Viennese Secession. The most notable works carried out at his golden age were the "Portrait of Adele Bloch-Bauer I" and "The kiss". In 1901 he paints "Medicine" where he returns to the entanglement of floating bodies -the lifetime- among which appears the skeleton of death; a female figure stands out from the column to represent freedom from pain. The figure of Hygeia or Hygieia, daughter of Aesculapius, who personifies medicine, is shown in the foreground. In 1911, thanks to "The life and death", a picture related to medicine, he was awarded the first prize at the Universal Exhibition of Rome. A number of his artworks were confiscated by the Nazi dictatorship. During the advance of enemy troops, and fearing that these works would become spoils of war, it was decided to burn the castle where they remained confiscated. Therefore, countless artworks were lost. The progressive development of symbolic or abstract motifs already emphasized the freedom of spirit that permeated all the avant-garde of early twentieth century.

    These images, taken by Galileo's solid state imaging system between November 1996 and June 1997, provide the first ever 'family portrait' of the four small, irregularly shaped moons that orbit Jupiter in the zone between the planet's ring and the larger Galilean satellites. The moons are shown in their correct relative sizes, with north approximately up in all cases. From left to right, arranged in order of increasing distance from Jupiter, are Metis (longest dimension is approximately 60 kilometers or 37 miles across), Adrastea (20 kilometers or 12 miles across), Amalthea (247 kilometers or 154 miles across), and Thebe (116 kilometers or 72 miles across). While Amalthea, the largest of these four tiny moons, was imaged by NASA's two Voyager spacecraft in 1979 with a resolution comparable to what is shown here, the new Galileo observations represent the first time that Metis, Adrastea, and Thebe have been seen as more than points of light.The Jet Propulsion Laboratory, Pasadena, CA manages the Galileo mission for NASA's Office of Space Science, Washington, DC.

  7. Adaptation effects to attractiveness of face photographs and art portraits are domain-specific

    We studied the neural coding of facial attractiveness by investigating effects of adaptation to attractive and unattractive human faces on the perceived attractiveness of veridical human face pictures (Experiment 1) and art portraits (Experiment 2). Experiment 1 revealed a clear pattern of contrastive aftereffects. Relative to a pre-adaptation baseline, the perceived attractiveness of faces was increased after adaptation to unattractive faces, and was decreased after adaptation to attractive faces. Experiment 2 revealed similar aftereffects when art portraits rather than face photographs were used as adaptors and test stimuli, suggesting that effects of adaptation to attractiveness are not restricted to facial photographs. Additionally, we found similar aftereffects in art portraits for beauty, another aesthetic feature that, unlike attractiveness, relates to the properties of the image (rather than to the face displayed). Importantly, Experiment 3 showed that aftereffects were abolished when adaptors were art portraits and face photographs were test stimuli. These results suggest that adaptation to facial attractiveness elicits aftereffects in the perception of subsequently presented faces, for both face photographs and art portraits, and that these effects do not cross image domains.

  8. How did Leonardo perceive himself? Metric iconography of da Vinci's self-portraits

    Some eighteen portraits are now recognized of Leonardo in old age, consolidating the impression from his bestestablished self-portrait of an old man with long white hair and beard. However, his appearance when younger is generally regarded as unknown, although he was described as very beautiful as a youth. Application of the principles of metric iconography, the study of the quantitative analysis of the painted images, provides an avenue for the identification of other portraits that may be proposed as valid portraits of Leonardo during various stages of his life, by himself and by his contemporaries. Overall, this approach identifies portraits of Leonardo by Verrocchio, Raphael, Botticelli, and others. Beyond this physiognomic analysis, Leonardo's first known drawing provides further insight into his core motivations. Topographic considerations make clear that the drawing is of the hills behind Vinci with a view overlooking the rocky promontory of the town and the plain stretching out before it. The outcroppings in the foreground bear a striking resemblance to those of his unique composition, 'The Virgin of the Rocks', suggesting a deep childhood appreciation of this wild terrain. and an identification with that religious man of the mountains, John the Baptist, who was also the topic of Leonardo's last known painting. Following this trail leads to a line of possible selfportraits continuing the age-regression concept back to a self view at about two years of age.

    Skin and soft tissue infections (SSTIs) caused by mupirocin-resistant Staphylococcus aureus strains have recently increased in number in our settings. We sought to evaluate the characteristics of these cases over a 43-month period. Data for all community-acquired staphylococcal infections caused by mupirocin-resistant strains were retrospectively reviewed. Genes encoding products producing high-level resistance (HLR) to mupirocin ( mupA ), fusidic acid resistance ( fusB ), resistance to macrolides and lincosamides ( ermC and ermA ), Panton-Valentine leukocidin (PVL) ( lukS/lukF -PV), exfoliative toxins ( eta and etb ), and fibronectin binding protein A ( fnbA ) were investigated by PCRs in 102 selected preserved strains. Genotyping was performed by SCC mec and agr typing, whereas clonality was determined by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). A total of 437 cases among 2,137 staphylococcal infections were recorded in 2013 to 2016; they were all SSTIs with the exception of 1 case of primary bacteremia. Impetigo was the predominant clinical entity (371 cases [84.9%]), followed by staphylococcal scalded skin syndrome (21 cases [4.8%]), and there were no abscesses. The number of infections detected annually increased during the study years. All except 3 isolates were methicillin susceptible. The rates of HLR to mupirocin and constitutive resistance to clindamycin were 99% and 20.1%, respectively. Among the 102 tested strains, 100 (98%) were mupA positive and 97 (95%) were fusB positive, 26/27 clindamycin-resistant strains (96.3%) were ermA positive, 83 strains (81.4%) were lukS/lukF positive, 95 (93%) carried both eta and etb genes, and 99 (97%) were fnbA positive. Genotyping of methicillin-sensitive S. aureus (MSSA) strains revealed that 96/99 (96.7%) belonged to one main pulsotype, pulsotype 1, classified as sequence type 121 (ST121). The emergence of a single MSSA clone (ST121) causing impetigo was documented. Resistance to

    Full Text Available Germline mutations in BRCA1, BRCA2 and TP53 genes have been identified as one of the most important disease-causing issues in young breast cancer patients worldwide. The specific defective biological processes that trigger germline mutation-associated and -negative tumors remain unclear. To delineate an initial portrait of Brazilian early-onset breast cancer, we performed an investigation combining both germline and tumor analysis. Germline screening of the BRCA1, BRCA2, CHEK2 (c.1100delC and TP53 genes was performed in 54 unrelated patients <35 y; their tumors were investigated with respect to transcriptional and genomic profiles as well as hormonal receptors and HER2 expression/amplification. Germline mutations were detected in 12 out of 54 patients (22% [7 in BRCA1 (13%, 4 in BRCA2 (7% and one in TP53 (2% gene]. A cancer familial history was present in 31.4% of the unrelated patients, from them 43.7% were carriers for germline mutation (37.5% in BRCA1 and in 6.2% in the BRCA2 genes. Fifty percent of the unrelated patients with hormone receptor-negative tumors carried BRCA1 mutations, percentage increasing to 83% in cases with familial history of cancer. Over-representation of DNA damage-, cellular and cell cycle-related processes was detected in the up-regulated genes of BRCA1/2-associated tumors, whereas cell and embryo development-related processes were over-represented in the up-regulated genes of BRCA1/2-negative tumors, suggesting distinct mechanisms driving the tumorigenesis. An initial portrait of the early-onset breast cancer patients in Brazil was generated pointing out that hormone receptor-negative tumors and positive familial history are two major risk factors for detection of a BRCA1 germline mutation. Additionally, the data revealed molecular factors that potentially trigger the tumor development in young patients.

    This paper describes a self-portrait scoring system and compares the self-portraits of two groups of adults. The scoring system effectively differentiated between the two groups of subjects which were known to differ on several observable behavioral characteristics. It correlated well with the ratings obtained from counselors but not with a self-report inventory of anxiety. A self-portrait is a single manifestation of an individual's self-concept. It presents only a fraction of the hypothetical universe of one's behavioral manifestations. In addition, every single observation is affected by the place, time, and the presence of the observer. However, if these isolated observations can be studied systematically, they can contribute to a reliable and a valid index of the self-concept. This paper presents one means of achieving that end.

    2015-08-01

    A portrait of uncertain origin recently came to light which, after extensive research and examination, was shown to be that rarest of things: a newly discovered Leonardo da Vinci painting entitled La Bella Principessa. This research presents a new illusion which is similar to that identified in the Mona Lisa; La Bella Principessa's mouth appears to change slant depending on both the Viewing Distance and the Level of Blur applied to a digital version of the portrait. Through a series of psychophysics experiments, it was found that a perceived change in the slant of the La Bella Principessa's mouth influences her expression of contentment thus generating an illusion that we have coined the "uncatchable smile". The elusive quality of the Mona Lisa's smile has been previously reported (Science, 290 (2000) 1299) and so the existence of a similar illusion in a portrait painted prior to the Mona Lisa becomes more interesting. The question remains whether Leonardo da Vinci intended this illusion. In any case, it can be argued that the ambiguity created adds to the portrait's allure. Copyright © 2015 Elsevier Ltd.

  11. The PIN1 family gene PvPIN1 is involved in auxin-dependent root emergence and tillering in switchgrass

    Directory of Open Access Journals (Sweden)

    Kaijie Xu

    2016-03-01

    Full Text Available Abstract Switchgrass (Panicum virgatum L.; family Poaceae is a warm-season C4 perennial grass. Tillering plays an important role in determining the morphology of aboveground parts and the final biomass yield of switchgrass. Auxin distribution in plants can affect a variety of important growth and developmental processes, including the regulation of shoot and root branching, plant resistance and biological yield. Auxin transport and gradients in plants are mediated by influx and efflux carriers. PvPIN1, a switchgrass PIN1-like gene that is involved in regulating polar transport, is a putative auxin efflux carrier. Neighbor-joining analysis using sequences deposited in NCBI databases showed that the PvPIN1gene belongs to the PIN1 family and is evolutionarily closer to the Oryza sativa japonica group. Tiller emergence and development was significantly promoted in plants subjected toPvPIN1 RNA interference (RNAi, which yielded a phenotype similar to that of wild-type plants treated with the auxin transport inhibitor TIBA (2,3,5-triiodobenzoic acid. A transgenic approach that inducedPvPIN1 gene overexpression or suppression altered tiller number and the shoot/root ratio. These data suggest that PvPIN1plays an important role in auxin-dependent adventitious root emergence and tillering.

    Directory of Open Access Journals (Sweden)

    Ratana Tacharoenmuang

    Full Text Available The emergence and rapid spread of unusual DS-1-like intergenogroup reassortant rotavirus strains have been recently reported in Asia, Australia, and Europe. During rotavirus surveillance in Thailand in 2013-2014, novel DS-1-like intergenogroup reassortant strains having G8P[8] genotypes (i.e., strains KKL-17, PCB-79, PCB-84, PCB-85, PCB-103, SKT-107, SWL-12, NP-130, PCB-656, SKT-457, SSKT-269, and SSL-55 were identified in stool samples from hospitalized children with severe diarrhea. In this study, we determined and characterized the complete genomes of these 12 strains (seven strains, KKL-17, PCB-79, PCB-84, PCB-85, PCB-103, SKT-107, and SWL-12, found in 2013 (2013 strains, and five, NP-130, PCB-656, SKT-457, SSKT-269, and SSL-55, in 2014 (2014 strains. On full genomic analysis, all 12 strains showed a unique genotype constellation comprising a mixture of genogroup 1 and 2 genes: G8-P[8]-I2-R2-C2-M2-A2-N2-T2-E2-H2. With the exception of the G genotype, the unique genotype constellation of the 12 strains (P[8]-I2-R2-C2-M2-A2-N2-T2-E2-H2 was found to be shared with DS-1-like intergenogroup reassortant strains. On phylogenetic analysis, six of the 11 genes of the 2013 strains (VP4, VP2, VP3, NSP1, NSP3, and NSP5 appeared to have originated from DS-1-like intergenogroup reassortant strains, while the remaining four (VP7, VP6, VP1, and NSP2 and one (NSP4 gene appeared to be of bovine and human origin, respectively. Thus, the 2013 strains appeared to be reassortant strains as to DS-1-like intergenogroup reassortant, bovine, bovine-like human, and/or human rotaviruses. On the other hand, five of the 11 genes of the 2014 strains (VP4, VP2, VP3, NSP1, and NSP3 appeared to have originated from DS-1-like intergenogroup reassortant strains, while three (VP7, VP1, and NSP2 and one (NSP4 were assumed to be of bovine and human origin, respectively. Notably, the remaining two genes, VP6 and NSP5, of the 2014 strains appeared to have originated from locally

    Emergence of races in Fusarium oxysporum f. sp. lycopersici (Fol) is caused by loss or mutation of at least one avirulence (AVR) gene. The product of AVR1 is a small protein (Avr1) secreted by Fol in tomato xylem sap during infection. This protein triggers Fol race 1 specific resistance (I) in tomato, indicating that AVR1 is an AVR gene. Deletion of AVR1 in race 1 resulted in the emergence of race 2, and an additional mutation in AVR2 generated race 3. Previously, we reported a new biotype of race 3, KoChi-1, in which AVR1 was truncated by a transposon Hormin, which suggested a new route to evolution of races in Fol However, to date no race 2 isolate carrying Hormin-truncated AVR1 has been reported. In this report, we describe such isolates, represented by Chiba-5, in which Hormin insertion occurred in AVR1 at a position different from that in KoChi-1. AVR1 truncation in both isolates resulted in production of defective Avr1 proteins. Chiba-5 and KoChi-1 belong to different phylogenetic clades, A1 and A2, respectively, suggesting that insertion of Hormin in AVR1 in Chiba-5 and KoChi-1 occurred as independent evolutionary events. © FEMS 2016.

    New antivirals are required to prevent rising antimicrobial resistance from replication inhibitors. The aim of this study was to analyse the range of emerging mutations in herpesvirus by whole genome deep sequencing. We tested human herpesvirus 6 treatment with novel antiviral K21, where evidence indicated distinct effects on virus envelope proteins. We treated BACmid cloned virus in order to analyse mechanisms and candidate targets for resistance. Illumina based next generation sequencing technology enabled analyses of mutations in 85 genes to depths of 10,000 per base detecting low prevalent minority variants (<1%). After four passages in tissue culture the untreated virus accumulated mutations in infected cells giving an emerging mixed population (45-73%) of non-synonymous SNPs in six genes including two envelope glycoproteins. Strikingly, treatment with K21 did not accumulate the passage mutations; instead a high frequency mutation was selected in envelope protein gQ2, part of the gH/gL complex essential for herpesvirus infection. This introduced a stop codon encoding a truncation mutation previously observed in increased virion production. There was reduced detection of the glycoprotein complex in infected cells. This supports a novel pathway for K21 targeting virion envelopes distinct from replication inhibition. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

    The discoloration of ancient paper, due to the development of oxidized groups acting as chromophores in its chief component, cellulose, is responsible for severe visual degradation in ancient artifacts. By adopting a non-destructive approach based on the combination of optical reflectance measurements and time-dependent density functional theory ab-initio calculations, we describe and quantify the chromophores affecting Leonardo da Vinci's iconic self-portrait. Their relative concentrations are very similar to those measured in modern and ancient samples aged in humid environments. This analysis quantifies the present level of optical degradation of the Leonardo da Vinci's self-portrait which, compared with future measurements, will assess its degradation rate. This is a fundamental information in order to plan appropriate conservation strategies.

  2. Le portrait d’enfants – entre statut social et art photographique

    Full Text Available Special attention was offered to the infantile portrait in the 19th century studio photography. This was also the most difficult to make because of the agility or timidity of the models. The photographer must have shown good parenting skills and a lot of diplomacy – and, why not, cleverness – to convince the little model to stand still for a few seconds while the photograph was taken. Without too much alienation from the standards of the studio portrait, the photographer used to give vent to the fantasy when the client was a child. In many cases many pieces of photographic art were made this way and after many years still represent the impersonation of the childhood that is long gone.

    Full Text Available My critical musings on this little-known maternal self-portrait are meant to reconceive its meaning as an uncanny predecessor to contemporary feminist embodied knowledge. This knowledge holds the potential for articulating new strategies of respect for the maternal and for the real mother, in other words for thinking m(otherwise. This portent photograph not only presented a non-normative concept of pregnancy during its cultural moment; it continues to challenge the deep patriarchal “embarrassment” that pregnancy carries. Arbus’ performance of the maternal was crafted within her creative practice and deeply embedded within a new maternal structure of projected work and self. Picturing herself as artist/photographer, other, lover and projected mother, she embodies a creative interplay between the passion of theory and the thinking body.   This photograph can be viewed at https://onlineonly.christies.com/s/photographs-diane-arbus/self-portrait-pregnant-n-y-c-1945-1/222.

  4. HUBBLE'S PANORAMIC PORTRAIT OF A VAST STAR-FORMING REGION

    Science.gov (United States)

    2002-01-01

    NASA's Hubble Space Telescope has snapped a panoramic portrait of a vast, sculpted landscape of gas and dust where thousands of stars are being born. This fertile star-forming region, called the 30 Doradus Nebula, has a sparkling stellar centerpiece: the most spectacular cluster of massive stars in our cosmic neighborhood of about 25 galaxies. The mosaic picture shows that ultraviolet radiation and high-speed material unleashed by the stars in the cluster, called R136 [the large blue blob left of center], are weaving a tapestry of creation and destruction, triggering the collapse of looming gas and dust clouds and forming pillar-like structures that are incubators for nascent stars. The photo offers an unprecedented, detailed view of the entire inner region of 30 Doradus, measuring 200 light-years wide by 150 light-years high. The nebula resides in the Large Magellanic Cloud (a satellite galaxy of the Milky Way), 170,000 light-years from Earth. Nebulas like 30 Doradus are the 'signposts' of recent star birth. High-energy ultraviolet radiation from the young, hot, massive stars in R136 causes the surrounding gaseous material to glow. Previous Hubble telescope observations showed that R136 contains several dozen of the most massive stars known, each about 100 times the mass of the Sun and about 10 times as hot. These stellar behemoths all formed at the same time about 2 million years ago. The stars in R136 are producing intense 'stellar winds' (streams of material traveling at several million miles an hour), which are wreaking havoc on the gas and dust in the surrounding neighborhood. The winds are pushing the gas away from the cluster and compressing the inner regions of the surrounding gas and dust clouds [the pinkish material]. The intense pressure is triggering the collapse of parts of the clouds, producing a new generation of star formation around the central cluster. The new stellar nursery is about 30 to 50 light-years from R136. Most of the stars in the

    Full Text Available Abstract. The date of ear emergence (DEE and the date (time of physiological maturity (TPM, as quantitative indication affect yield and in this respect any information about their genetic nature is important for breeding in climatic anomalies of the country. This study aims to give a detailed analysis of the succession of traits DEE and TPM to gather updated information on the genetic control of contrast by combining traits varieties. We studied six generations originating from 6 hybrid combinations of "early " and "late " with respect to the varieties of both traits. It was determine the type of inheritance and coefficients of heritability. To identify real opportunities for breeding of early forms recurrent combinations with each of the parental varieties are made. Data suggest complex interactions between genes for both traits .An inspection for the presence of epistas by applying the well-known 3-parameter test, is calculated. For additional information components of genetic diversity were calculated. In crosses in which is found non-allelic interaction is applied 6 - parameter model, that explains the specific nature of these interactions on a cross. The combination of varieties with different dates of ear emergence and maturation succession of both traits is partially dominant to the complete domination of the "late" parent. Performing backcross procedure changes significantly in direct proportion to recurrent that in late varieties causes heterosis . At 2 /3 of the combinations studied non-allelic interaction are set at both traits. On the inheritance of every trait share a non-allelic interactions between genes that are specific for each cross and defy generalization. The direction of the inheritance to the later date suggests that the breeding of the early forms is preferable by making recurrent crosses . Earlier of ear emergence date varieties as Enola, Galatea and Obrii should be used in terms of a compromise combination of early ear

    Purpose: To compare the dosimetric properties of radiochromic films with different orientation. Methods: A sheet of EBT3 film was cut into eight pieces with the following sizes: 15×15 cm2 (one piece), 5x15 cm 2 (two) and 4×5 cm 2 (five). A set of two EBT3 sheets was used at each dose level. Two sets were used changing the delivered doses (1 and 2 Gy). The 5×15 cm 2 pieces were rotated by 90 degrees in relation to each other, such that one had landscape orientation and the other had portrait orientation. All 5×15 cm2 pieces were irradiated with their long side aligned with the x-axis of the radiation field. The 15×15 cm 2 pieces were irradiated rotated at 90 degrees to each other. Five pieces, (a total of ten from two sheets) were used to obtain a calibration curve. The irradiated films were scanned using an Epson ES-2200 scanner and were analyzed using ImageJ software. In this study, no correction was applied for the nonuniform scanner signal that is evident in the direction of the scanner lamp. Each film piece was scanned both in portrait and landscape orientations. Dosimetric comparisons of the beam profiles were made in terms of the film orientations (portrait and landscape) and scanner bed directions (perpendicular and parallel to the scanner movement). Results: In general, portrait orientation exhibited higher noise than landscape and was adversely affected to a great extent by the nonuniformity in the direction of the scanner lamp. A significant difference in the measured field widths between the perpendicular and parallel directions was found for both orientations. Conclusion: Without correction for the nonuniform scanner signal in the direction of the scanner lamp, a landscape orientation is preferable. A more detailed investigation is planned to evaluate quantitatively the effect of orientation on the dosimetric properties of a film

    Avian influenza viruses of subtype H9N2 are widely prevalent in poultry in many Asian countries, and the segmented nature of the viral genome results in multiple distinct genotypes via reassortment. In this study, genetic evolution of H9N2 viruses circulating in eastern China during 2007-2013 was analyzed. The results showed that the diversity of the gene constellations generated six distinct genotypes, in which a novel genotype (S) bearing the backbone of A/chicken/Shanghai/F/98-like viruses by acquiring A/quail/Hong Kong/G1/97-like polymerase basic subunit 2 and matrix genes has gradually established its ecological niche and been consistently prevalent in chicken flocks in eastern China since its first detection in 2007. Furthermore, genotype S possessed the peculiarity to donate most of its gene segments to other emerging influenza A viruses in China, including the novel reassortant highly pathogenic avian influenza H5N2, the 2013 novel H7N7, H7N9 and the latest reassortant H10N8 viruses, with potential threat to poultry industry and human health.

    2016-01-01

    This study explored why nurses chose to remain in the Western Australian workforce and to develop insights into the role of resilience of nurses and to identify the key characteristics of resilience displayed by these nurses. Nursing is a stressful profession. Prolific quantitative research which measures job stress and resilience has been implemented; however, there is a dearth of qualitative studies which hear the personal narratives as to why nurses remain and thrive in a stressful workplace. Vignettes of nursing resilience reveal underlying themes of resilience where personal stories and events are presented as narrative. Portraiture recognises the inherent value of the nurses' stories giving attention to the nature of their resilience. Interpretation illuminates the portraits or verbal canvasses of the told experience, reflecting success and positivity despite disarray in healthcare settings. Eight themes were identified. The portraits highlight a sometimes imperceptible theme of resilience within nursing. Nurses are resilient; they rely on the social support of colleagues, family and friends to continue to bear their mantle of responsibility. They take pride in their work and accomplishments and give to others altruistically. They laugh, they love nursing and they keep the needs of their patients, clients, residents or students foremost. This paper describes the hallmarks of resilience demonstrated by nurses. Resilience and its relationship to coping in times of adversity are captured within the portraits presented.

  13. Painterly rendered portraits from photographs using a knowledge-based approach

    2007-02-01

    Portrait artists using oils, acrylics or pastels use a specific but open human vision methodology to create a painterly portrait of a live sitter. When they must use a photograph as source, artists augment their process, since photographs have: different focusing - everything is in focus or focused in vertical planes; value clumping - the camera darkens the shadows and lightens the bright areas; as well as color and perspective distortion. In general, artistic methodology attempts the following: from the photograph, the painting must 'simplify, compose and leave out what's irrelevant, emphasizing what's important'. While seemingly a qualitative goal, artists use known techniques such as relying on source tone over color to indirect into a semantic color temperature model, use brush and tonal "sharpness" to create a center of interest, lost and found edges to move the viewers gaze through the image towards the center of interest as well as other techniques to filter and emphasize. Our work attempts to create a knowledge domain of the portrait painter process and incorporate this knowledge into a multi-space parameterized system that can create an array of NPR painterly rendering output by analyzing the photographic-based input which informs the semantic knowledge rules.

    Genetic differences that specify unique aspects of human evolution have typically been identified by comparative analyses between the genomes of humans and closely related primates, including more recently the genomes of archaic hominins. Not all regions of the genome, however, are equally amenable to such study. Recurrent copy number variation (CNV) at chromosome 16p11.2 accounts for approximately 1% of cases of autism and is mediated by a complex set of segmental duplications, many of which arose recently during human evolution. Here we reconstruct the evolutionary history of the locus and identify bolA family member 2 (BOLA2) as a gene duplicated exclusively in Homo sapiens. We estimate that a 95-kilobase-pair segment containing BOLA2 duplicated across the critical region approximately 282 thousand years ago (ka), one of the latest among a series of genomic changes that dramatically restructured the locus during hominid evolution. All humans examined carried one or more copies of the duplication, which nearly fixed early in the human lineage--a pattern unlikely to have arisen so rapidly in the absence of selection (P sapiens-specific duplication. In summary, the duplicative transposition of BOLA2 at the root of the H. sapiens lineage about 282 ka simultaneously increased copy number of a gene associated with iron homeostasis and predisposed our species to recurrent rearrangements associated with disease.

    Yersinia pestis, the causative agent of bubonic andpneumonicplague, has undergone detailed study at the molecular level. Tofurther investigate the genomic diversity among this group and to helpcharacterize lineages of the plague organism that have no sequencedmembers, we present here the genomes of two isolates of the "classical"Antiqua biovar, strains Antiqua and Nepal516. The genomes of Antiqua andNepal516 are 4.7 Mb and 4.5 Mb and encode 4,138 and 3,956 open readingframes respectively. Though both strains belong to one of the threeclassical biovars, they represent separate lineages defined by recentphylogenetic studies. We compare all five currently sequenced Y. pestisgenomes and the corresponding features in Y. pseudotuberculosis. Thereare strain-specific rearrangements, insertions, deletions, singlenucleotide polymorphisms and a unique distribution of insertionsequences. We found 453 single nucleotide polymorphisms in protein codingregions, which were used to assess evolutionary relationships of these Y.pestis strains. Gene reduction analysis revealed that the gene deletionprocesses are under selective pressure and many of the inactivations areprobably related to the organism s interaction with its host environment.The results presented here clearly demonstrate the differences betweenthe two Antiqua lineages and support the notion that grouping Y. pestisstrains based strictly on the classical definition of biovars (predicatedupon two biochemical assays) does not accurately reflect the phylogeneticrelationships within this species. Comparison of four virulent Y. pestisstrains with the human-avirulent strain 91001 provides further insightinto the genetic basis of virulence to humans.

    Sunflower oil is one of the major sources of edible oil. As the second largest hybrid crop in the world, hybrid sunflowers are developed by using the PET1 cytoplasmic male sterility system that contributes to a 20 % yield advantage over the open-pollinated varieties. However, sunflower production in North America has recently been threatened by the evolution of new virulent pathotypes of sunflower rust caused by the fungus Puccinia helianthi Schwein. Rf ANN-1742, an 'HA 89' backcross restorer line derived from wild annual sunflower (Helianthus annuus L.), was identified as resistant to the newly emerged rust races. The aim of this study was to elucidate the inheritance of rust resistance and male fertility restoration and identify the chromosome location of the underlying genes in Rf ANN-1742. Chi-squared analysis of the segregation of rust response and male fertility in F(2) and F(3) populations revealed that both traits are controlled by single dominant genes, and that the rust resistance gene is closely linked to the restorer gene in the coupling phase. The two genes were designated as R ( 11 ) and Rf5, respectively. A set of 723 mapped SSR markers of sunflower was used to screen the polymorphism between HA 89 and the resistant plant. Bulked segregant analysis subsequently located R ( 11 ) on linkage group (LG) 13 of sunflower. Based on the SSR analyses of 192 F(2) individuals, R ( 11 ) and Rf5 both mapped to the lower end of LG13 at a genetic distance of 1.6 cM, and shared a common marker, ORS728, which was mapped 1.3 cM proximal to Rf5 and 0.3 cM distal to R ( 11 ) (Rf5/ORS728/R ( 11 )). Two additional SSRs were linked to Rf5 and R ( 11 ): ORS995 was 4.5 cM distal to Rf5 and ORS45 was 1.0 cM proximal to R ( 11 ). The advantage of such an introduced alien segment harboring two genes is its large phenotypic effect and simple inheritance, thereby facilitating their rapid deployment in sunflower breeding programs. Suppressed recombination was observed in LGs 2, 9

    Enterococcus faecium recently evolved from a generally avirulent commensal into a multidrug-resistant health care-associated pathogen causing difficult-to-treat infections, but little is known about the factors responsible for this change. We previously showed that some E. faecium strains express a cell wall-anchored collagen adhesin, Acm. Here we analyzed 90 E. faecium isolates (99% acm(+)) and found that the Acm protein was detected predominantly in clinically derived isolates, while the acm gene was present as a transposon-interrupted pseudogene in 12 of 47 isolates of nonclinical origin. A highly significant association between clinical (versus fecal or food) origin and collagen adherence (P Acm detected by whole-cell enzyme-linked immunosorbent assay and flow cytometry. Thirty-seven of 41 sera from patients with E. faecium infections showed reactivity with recombinant Acm, while only 4 of 30 community and hospitalized patient control group sera reacted (P Acm were present in all 14 E. faecium endocarditis patient sera. Although pulsed-field gel electrophoresis indicated that multiple strains expressed collagen adherence, multilocus sequence typing demonstrated that the majority of collagen-adhering isolates, as well as 16 of 17 endocarditis isolates, are part of the hospital-associated E. faecium genogroup referred to as clonal complex 17 (CC17), which has emerged globally. Taken together, our findings support the hypothesis that Acm has contributed to the emergence of E. faecium and CC17 in nosocomial infections.

    Much attention has been given to the conservation of small populations, those that are small because of decline, and those that are naturally small. Small populations are of particular interest because ecological theory suggests that they are vulnerable to the deleterious effects of environmental, demographic, and genetic stochasticity as well as natural and human-induced catastrophes. However, testing theory and developing applicable conservation measures for small populations is hampered by sparse data. This lack of information is frequently driven by computational issues with small data sets that can be confounded by the impacts of stressors. We present estimates of demographic parameters from a small population of Boreal Toads (Anaxyrus boreas) that has been surveyed since 2001 by using capture-recapture methods. Estimates of annual adult survival probability are high relative to other Boreal Toad populations, whereas estimates of recruitment rate are low. Despite using simple models, clear patterns emerged from the analyses, suggesting that population size is constrained by low recruitment of adults and is declining slowly. These patterns provide insights that are useful in developing management directions for this small population, and this study serves as an example of the potential for small populations to yield robust and useful information despite sample size constraints.

  2. TOURISM COMPANIES AND THE FALS PORTRAIT GIVEN BY CREATIVE ACCOUNTING

    Full Text Available Theodore Roosevelt expressed so well the need and effectiveness of natural resources “To waste, to destroy our natural resources, to skin and exhaust the land instead of using it so as to increase its usefulness, will result in undermining in the days of our children the very prosperity which we ought by right to hand down to them amplified and developed” in parallel with his statement that "Human beings are unique in that they can learn from others' experience, but also through its refusal to make use of this capacity". Some companies use the knowledge of professional accountants to manipulate figures contained in the annual accounts, without paying attention to detect when "creativity” exceeds the limits imposed by law. Sometimes, professional accountants are convinced on the one hand by incompetent managers, and on the other hand if the business downturn of the need for improvements in the figures in the annual accounts. When asking why a company with the object of catering and tourism would resort to the practice of using creative accounting, the answer is clear from the application of the trends in the field and from the differences that emerged from the accounting procedures used by companies and the moment they are adopted

    In this paper, we propose an enabling computational and theoretical framework for the analysis of experimental instances of collective behavior in response to external stimuli. In particular, this work addresses the characterization of aggregation and interaction phenomena in robot-animal groups through the exemplary analysis of fish schooling in the vicinity of a biomimetic robot. We adapt global observables from statistical mechanics to capture the main features of the shoal collective motion and its response to the robot from experimental observations. We investigate the shoal behavior by using a diffusion mapping analysis performed on these global observables that also informs the definition of relevant portraits of self-organization.

    The Portrait Values Questionnaire (PVQ) is tested for cross-cultural validity. Measurement characteristics are compared across representative consumer samples from 25 European countries (total N = 37,592) using multi-group confirmatory factor analysis with structured means. The results suggest....... Hence, most direct comparisons of PVQ raw scores and sample statistics between European countries are valid without correction. Furthermore, it can be concluded that the ten values measured by the PVQ are invariant across European countries in terms of their relative position on the quasi......-circumplex hypothesised by the theory of basic human values....

  6. Short communication: Emergence of a new race of leaf rust with combined virulence to Lr14a and Lr72 genes on durum wheat

    Leaf rust is a foliar disease caused by the fungus Puccinia triticina that may severely reduce durum wheat yield. Resistance to this pathogen is common in modern durum germplasm but is frequently based on Lr72 and Lr14a. After accounts of races with virulence to Lr14a gene in France in 2000, the present study reports the detection in 2013 for the first time of a new race with virulence to Lr14a and Lr72. The aim of this work was to characterize the virulence pattern of four Spanish isolates with virulence to Lr14a, and to discuss the consequences of this presence. Rusted leaves from cultivars ‘Don Jaime’ (Lr14a) and ‘Gallareta’ (Lr72) were collected in 2013 in the field at two Spanish sites, one in the south (near Cadiz) and another in the north (near Girona). Spores from single pustule for each cultivar and site were multiplied on susceptible cultivar ‘Don Rafael’. Then, the four isolates were inoculated on a set of 19 isogenic lines Thatcher to characterize their virulence spectrum. All isolates presented the same virulence pattern. They were virulent on both Lr14a and Lr72 and the race was named DBB/BS. This race was very similar to those reported in 2009-11, but with added virulence to Lr14a. The resistance based on Lr14a has therefore been overcome in Spain, by a new race that has likely emerged via stepwise mutation from the local predominating races. This information is important to guide breeders in their breeding programmes and gene deployment strategies. (Author)

  7. fMRI-activation during drawing a naturalistic or sketchy portrait.

    Neural processes for naturalistic drawing might be discerned into object recognition and analysis, attention processes guiding eye hand interaction, encoding of visual features in an allocentric reference frame, a transfer into the motor command and precise motor guidance with tight sensorimotor feedback. Cerebral representations in a real life paradigm during naturalistic drawing have sparsely been investigated. Using a functional Magnetic Resonance Imaging (fMRI) paradigm we measured 20 naive subjects during drawing a portrait from a frontal face presented as a photograph. Participants were asked to draw the portrait in either a naturalistic or a sketchy characteristic way. Tracing the contours of the face with a pencil or passive viewing of the face served as control conditions. Compared to passive viewing, naturalistic and sketchy drawing recruited predominantly the dorsal visual pathway, somatosensory and motor areas and bilateral BA 44. The right occipital lobe, middle temporal (MT) and the fusiform face area were increasingly active during drawing compared to passive viewing as well. Compared to tracing with a pencil, both drawing tasks increasingly involved the bilateral precuneus together with the cuneus and right inferior temporal lobe. Overall, our study identified cerebral areas characteristic for previously proposed aspects of drawing: face perception and analysis (fusiform gyrus and higher visual areas), encoding and retrieval of locations in an allocentric reference frame (precuneus), and continuous feedback processes during motor output (parietal sulcus, cerebellar hemisphere).

  8. Self-Portrait of an Artist with a Book in her Hand

    Full Text Available This article considers the book as an important emancipatory motif, expressing the tendency of women self-portrait painters to present themselves as educated and accomplished, and to establish their own subjectivity. In traditional self-portraits, since the Renaissance some female artists have presented themselves as autonomous active individuals depicted painting, reading, or playing a musical instrument. In the past, the motif of the reader has symbolized female erudition, education, and sophistication. In a time when women could only rarely attend school, the use of this motif represented an important and liberating gesture. In a period when artists preferred to portray women as nude seducers rather than as learned ladies, it was all the more important that some female artists endeavored to stress the role of women as readers. Although images of women authors with a book in their hands represented a symbol of learning and wisdom, this same motif could also be used to replace a female author’s signature. This is examined here with reference to the works of the Renaissance painter Sofonisba Anguissola.

    Human content perception has been underlined to be important in multimedia quality evaluation. Recently aesthetic considerations have been subject of research in this field. First attempts in aesthetics took into account perceived low-level features, especially taken from photography theory. However they demonstrated to be insuf- ficient to characterize human content perception. More recently image psychology started to be considered as higher cognitive feature impacting user perception. In this paper we follow this idea introducing social cognitive elements. Our experiments focus on the influence of different versions of portrait pictures in context where they are showed aside some completely unrelated informations; this can happen for example in social networks interactions between users, where profile pictures are present aside almost every user action. In particular, we tested this impact on resumes between professional portrait and self shot pictures. Moreover, as we run tests in crowdsourcing, we will discuss the use of this methodology for these tests. Our final aim is to analyse social biases' impact on multimedia aesthetics evaluation and how this bias influences messages that go along with pictures, as in public online platforms and social networks.

    The global spread of carbapenem-resistant Enterobacteriaceae (CRE) is one of the most severe threats to human health in a clinical setting. The recent emergence of plasmid-mediated colistin resistance gene mcr-1 among CRE strains greatly compromises the use of colistin as a last resort for the treatment of infections caused by CRE. This study aimed to understand the current epidemiological trends and characteristics of CRE from a large hospital in Henan, the most populous province in China. From 2014 to 2016, a total of 7,249 Enterobacteriaceae isolates were collected from clinical samples, among which 18.1% (1,311/7,249) were carbapenem resistant. Carbapenem-resistant Klebsiella pneumoniae and carbapenem-resistant Escherichia coli were the two most common CRE species, with Klebsiella pneumoniae carbapenemases (KPC) and New Delhi metallo-β-lactamases (NDM), respectively, responsible for the carbapenem resistance of the two species. Notably, >57.0% ( n = 589) of the K. pneumoniae isolates from the intensive care unit were carbapenem resistant. Furthermore, bla NDM-5 and mcr-1 were found to coexist in one E. coli isolate, which exhibited resistance to almost all tested antibiotics. Overall, we observed a significant increase in the prevalence of CRE isolates during the study period and suggest that carbapenems may no longer be considered to be an effective treatment for infections caused by K. pneumoniae in the studied hospital.

Having the capacity of differentiating into the cells of all three primary germ layers, iPS cells have high potential to form teratoma tumors. This remains their main disadvantage and hazard which, until resolved, prevents utilization of iPS cells in clinic. Here, we present an approach for increasing iPS cells safety by introducing genetic modification—exogenous suicide gene Herpes Simplex Virus Thymidine Kinase (HSV-TK. Its expression results in specific vulnerability of genetically modified cells to prodrug—ganciclovir (GCV. We show that HSV-TK expressing cells can be eradicated both in vitro and in vivo with high specificity and efficiency with low doses of GCV. Described strategy increases iPS cells safety for future clinical applications by generating “emergency exit” switch allowing eradication of transplanted cells in case of their malfunction.

  16. An Attempt at Reconstruction of the Original Colour Scheme of the Paper Ground of Witkacy’s Portraits

    Full Text Available In the years 2005–2006 at a Restoration Workshop of Muzeum Pomorza Środkowego [Museum of Central Pomerania] in Słupsk, Witkacy’s portraits were framed in a new passe partout and glass pane. Based on the photographs taken then of fragments on which the colour of the paper ground was preserved, a computer reconstruction of the original colour of the paper was made. Comparison of the portraits with their probable original versions allows to risk a claim that nowadays we have to do with totally different pictures. The colour of the paper has changed considerably, e.g. from its initial violet it has turned into grey-beige. Equally big changes can be observed between the reverse and the face. When framing the portrait, restorers found an unfinished portrait on the reverse. The examples presented in this work show how important for the knowledge of the artist and his work is drawing attention to a single work of art, which is best to study directly and not through its reproductions or studies on it.

    genome reassortment, respectively. These evolutionary mechanisms generate novel strains and have the potential to lead to the emergence of vaccine escape mutants. While multiple African countries have introduced a rotavirus vaccine, there are few data describing the evolution of rotaviruses that circulated before and after vaccine introduction. We report the emergence of atypical DS-1-like G1P[8] strains during the postvaccine era in Malawi. Three distinct G1P[8] lineages circulated chronologically from 1998 to 2014; mutation and reassortment drove lineage turnover in 2005 and 2013, respectively. Amino acid substitutions within the outer capsid VP7 glycoprotein did not affect the structural conformation of mapped antigenic sites, suggesting a limited effect on the recognition of G1-specific vaccine-derived antibodies. The genes that constitute the remaining genetic backbone may play important roles in immune evasion, and vaccine effectiveness against such atypical strains needs careful evaluation.

    Although fluency theory predominates psychological research on human aesthetics, its most severe limitation may be to explain why art that challenges or even violates easy processing can nevertheless be aesthetically rewarding. We discuss long-standing notions on art's potential to offer mental growth opportunities and to tap into a basic epistemic predisposition that hint at a fluency counteracting aesthetic pleasure mechanism. Based on divergent strands of literature on empirical, evolutionary, and philosophical aesthetics, as well as research on disfluency, we presumed that challenging art requires deliberate reflexive processing at the level of "aboutness" in order to be experientially pleasing. Here, we probed such a cognitive mastering mechanism, achieved by iterative cycles of elaboration, as predicted by our model of aesthetic experiences. For the study, two kinds of portraits were applied, one associable to a high fluency and one to a high stimulation potential (according to results of an extensive rating study). In Experiment 1, we provided a repeated evaluation task, which revealed a distinctive preference effect for challenging portraits that was absent in the visual exposition conditions of a familiarity and a mere exposure task (Experiment 2). In a follow-up task (Experiment 3) this preference effect was observed with a novel and more encompassing pool of portraits, which corroborated its stability and robustness. In an explorative stimulus-transfer task (Experiment 4), we investigated the presumed underlying mechanism by testing whether the observed effect would generalize onto novel portraits of the same artist-specific styles. Results discounted an alternative interpretation of a perceptual adaptation effect and hinted at meaning-driven mental activity. Conjointly, findings for inexperienced viewers were indicative of an elaboration based mastering mechanism that selectively operated for mentally challenging portraits. Moreover, findings were in

    Full Text Available Georges Bataille believes that most of his contemporary discourses were spiritual and/or intellectual ones. They were, for him, vegetation-like discourses looking upward and underlining the role of head and thinking in their paradigms. He, instead, introduced the notion of "base materialism" which highlights the role of the lower parts of the body; it is here that Bataille raises the notion of "Acéphale" who has beheaded himself with a dagger in his right hand, and thus has beheaded the ruling head of his own body as well as the heads of his surrounding social discourses. For George Bataille, humans are linguistic being entrapped forever in a language system. However, he believes that this system is full of fissures and that through transgressive moments one can experience these voids within language. Through transgression one can look directly in the abyss of language, though he/she cannot see the extremity of these voids and thus Bataille believes that one cannot reach any signified, and therefore, any Bataillean "Impossible." As one can witness, linguistic human being is entrapped within narratives of language system defining him in terms of cause and effect and their related items namely linear time and space. Georges Bataille believes that any heterogeneous element which crosses the defined taboos of the body of self and society at some transgressive moments is regarded as a "foreign body" and an "alterity." This foreign body, as he regards, at the instants of transgression experiences "sovereignty" which means that he is at the epic of being a "sovereign being," of course momentarily, because he at those moments has stepped upon any ruling borders and is bound with no taboo and thus is the "sovereign" of instants. The present study endeavors to analyze Stephen Dedalus in A Portrait of the Artist as a Young Man and his Bataillean experiences in terms of narrative and language.

    Many environmental endocrine-disrupting compounds act as ligands for nuclear receptors. Among these receptors, the human pregnane X receptor (hPXR) is well described as a xenobiotic sensor to various classes of chemicals, including pharmaceuticals, pesticides, and steroids. To assess the potential use of PXR as a sensor for aquatic emerging pollutants, we employed an in vitro reporter gene assay (HG5LN-hPXR cells) to screen a panel of environmental chemicals and to assess PXR-active chemicals in (waste) water samples. Of the 57 compounds tested, 37 were active in the bioassay and 10 were identified as new PXR agonists: triazin pesticides (promethryn, terbuthryn, terbutylazine), pharmaceuticals (fenofibrate, bezafibrate, clonazepam, medazepam) and non co-planar polychlorobiphenyls (PCBs; PCB101, 138, 180). Furthermore, we detected potent PXR activity in two types of water samples: passive polar organic compounds integrative sampler (POCIS) extracts from a river moderately impacted by agricultural and urban inputs and three effluents from sewage treatment works (STW). Fractionation of POCIS samples showed the highest PXR activity in the less polar fraction, while in the effluents, PXR activity was mainly associated with the dissolved water phase. Chemical analyses quantified several PXR-active substances (i.e., alkylphenols, hormones, pharmaceuticals, pesticides, PCBs, bisphenol A) in POCIS fractions and effluent extracts. However, mass-balance calculations showed that the analyzed compounds explained only 0.03% and 1.4% of biological activity measured in POCIS and STW samples, respectively. In effluents, bisphenol A and 4-tert-octylphenol were identified as main contributors of instrumentally derived PXR activities. Finally, the PXR bioassay provided complementary information as compared to estrogenic, androgenic, and dioxin-like activity measured in these samples. This study shows the usefulness of HG5LN-hPXR cells to detect PXR-active compounds in water samples

    Full Text Available The interest in European masters from the past was a phenomenon related to the development of the artistic careers of many artists in Australia at the end of the nineteenth and beginning of the twentieth century. More than that, the copying or emulation of great works of art was seen to be a necessary part of an artist’s training1. This paper looks at Hugh Ramsay and his fascination with the painting Las Meninas (1656 by Velázquez as part of a larger study into understanding how the Spanish in uence was re ected in Australian art. Ramsay introduced elements from Las Meninas into his Portrait of the artist standing before easel, which took him to personify the role of the painter as Velázquez.

  10. Geometric Model of Black Hole Quantum N-portrait, Extradimensions and Thermodynamics

    Full Text Available Recently a short scale modified black hole metric, known as holographic metric, has been proposed in order to capture the self-complete character of gravity. In this paper we show that such a metric can reproduce some geometric features expected from the quantum N-portrait beyond the semi-classical limit. We show that for a generic N this corresponds to having an effective energy momentum tensor in Einstein equations or, equivalently, non-local terms in the gravity action. We also consider the higher dimensional extension of the metric and the case of an AdS cosmological term. We provide a detailed thermodynamic analysis of both cases, with particular reference to the repercussions on the Hawking-Page phase transition.

    Full Text Available The subject of this paper is a fragmented oil-lamp, discovered at Pontes (east Serbia dated to the 6th century, whose handle ending is shaped as a woman’s head. The question posed in this paper is whether the image of this woman could be identified as a portrait of some particular person or if it is just as a pictorial sign with some complicated symbolic meaning. The suggested identification alludes to the image of some of the empresses from the second half of the 6th century.

    Objectives To see whether a collection of portraits depicting inhabitants of a defined geographical region and covering several centuries is a useful source for studying the sociocultural significance and epidemiology of particular visible diseases, such as goitre, which is known to have been common in this region. Design Systematic review of portraits and description of visible signs of illness. Setting The Burgerbibliothek (archives of the burghers' community) in Berne, Switzerland. Data sources 3615 portraits; 2989 of individuals whose identity is known and 626 of individuals whose identity is unknown. Main outcome measures Visible signs of illness evaluated by means of a standardised visual assessment. Results Visible signs of illness in portraits were common and appeared in up to 82% (451/553) of paintings from the 17th and 18th centuries. The most common findings were signs of goitre in women and overweight in men. In only the portraits where the neck region could be evaluated, 41% of women with known identities (139/343) had goitre compared with 24% of men with known identities (21/86). The prevalence of goitre was even higher in sitters whose identities were unknown: 63% in men (5/8) and 68% in women (82/121). Overweight in people with known identities was more common in men than in women (30%, 346/1145 v 44%, 811/1844). Overweight was most common in sitters aged >40 than in those aged 40 or younger. Other conditions, such as missing teeth, amputated limbs, or osteoarthritic deformations were surprisingly rare in the portraits under evaluation. Conclusions Goitre and other diseases are under-represented in the people depicted in these portraits. Artistic idealisation is a likely explanation for this observation: what was reproduced depended on what was considered pathological or shameful at the time, and therefore depended on age and sex. Stigmatising details may have been omitted. Further, artistic skills and contemporary fashion may have influenced the

  15. SOCIAL PORTRAIT OF RURAL TEACHERS: THE RESULTS OF A COMPARATIVE SOCIOLOGICAL STUDY COUNTRY AND CITY TEACHERS

    Full Text Available The article presents the results of application of the comparative sociological study of rural and urban schools. The characteristic of a social portrait of the rural teacher. The basic social problems, an assessment of social well-being of rural and urban teachers. Purpose. The authors aimed to identify specific problems of the rural school for making sound management decisions in the field of social educational policy. Methodology. A comparative type of applied sociological research is realized by applying such methodological approaches as structural and functional analysis and its variety – typological analysis [2; 3; 5]. Results. In summary, the social portrait of a rural educator is characterized by the following social characteristics. He lives mostly in his own house. One member of his family has, mainly, 12-18 or more square meters of living space. Entrepreneurship and tutoring are poorly distributed in rural areas. In comparison with urban teachers, rural teachers are more oriented to vocational training, rather than to the formation of spiritual and intellectual culture of students. This is the practicality of the rural educator. Employment in the subsidiary farm is also the reason for the greater practicality of the rural teacher and his relatively low spiritual activity. In rural educational institutions the level of collectivism is higher, but the desire for individual achievements is lower. Practical implications. The management of social processes at the level of a rural school can be implemented in the form of social planning, drawing up of social programs, social projects aimed at solving social problems of a rural teacher and optimizing the development of a rural school.

    Full Text Available A Portrait of the Artist as a Young Man, written in 1916, is an authobiography and the first novel of the great Irish writer, James Joyce. It's written in Modernist style. So it can be contain of some category of realism, naturalism, and Marxism which aroused in mid-to late nineteenth century. But it mostly included realistic style because of the begining date of this literary school. By reading all works of James Joyce is maybe committing ownself to a  outstanding trickary world of  "chaosmos" (Finnegans Wake, p. 118.21, which stands for poetic mystery that few writers have acheived. In this study attempted is made to survey the main Protagonist in A Portrait of the Artist as a Young Man, and Ulysses, Stephen Dedalus, and its relationship to the author.

  1. A gene transfer agent and a dynamic repertoire of secretion systems hold the keys to the explosive radiation of the emerging pathogen Bartonella.

    Full Text Available Gene transfer agents (GTAs randomly transfer short fragments of a bacterial genome. A novel putative GTA was recently discovered in the mouse-infecting bacterium Bartonella grahamii. Although GTAs are widespread in phylogenetically diverse bacteria, their role in evolution is largely unknown. Here, we present a comparative analysis of 16 Bartonella genomes ranging from 1.4 to 2.6 Mb in size, including six novel genomes from Bartonella isolated from a cow, two moose, two dogs, and a kangaroo. A phylogenetic tree inferred from 428 orthologous core genes indicates that the deadly human pathogen B. bacilliformis is related to the ruminant-adapted clade, rather than being the earliest diverging species in the genus as previously thought. A gene flux analysis identified 12 genes for a GTA and a phage-derived origin of replication as the most conserved innovations. These are located in a region of a few hundred kb that also contains 8 insertions of gene clusters for type III, IV, and V secretion systems, and genes for putatively secreted molecules such as cholera-like toxins. The phylogenies indicate a recent transfer of seven genes in the virB gene cluster for a type IV secretion system from a cat-adapted B. henselae to a dog-adapted B. vinsonii strain. We show that the B. henselae GTA is functional and can transfer genes in vitro. We suggest that the maintenance of the GTA is driven by selection to increase the likelihood of horizontal gene transfer and argue that this process is beneficial at the population level, by facilitating adaptive evolution of the host-adaptation systems and thereby expansion of the host range size. The process counters gene loss and forces all cells to contribute to the production of the GTA and the secreted molecules. The results advance our understanding of the role that GTAs play for the evolution of bacterial genomes.

    Many forms of art accurately depict physical attributes of their subjects. But how precisely do portraits capture personal, emotional, and behavioral aspects of individuals holding leadership positions in academic departments of anesthesiology? We examined formal portraits of the first three academic chairmen of anesthesiology in our department - Leroy D. Vandam, Benjamin G. Covino, and Simon Gelman and obtained information about the artists (George Augusta and Marc Klionsky) regarding how they conducted research on their subjects, and the methods they used to depict significant character traits into their art. We then correlated the artistic depiction with known biographical and behavioral qualities of these leaders. We found that the artists were remarkably astute in their observations and that they successfully captured both physical and emotional aspects of these chairmen in their portraits. Moreover, in one instance, significant early life experiences were added to the composition with subtlety. Individuals familiar with these chairmen and aware of their management style can easily appreciate the techniques employed by the artists. We conclude that art successfully depicted personal and executive attributes of these three academic anesthesia chairmen. Copyright © 2016 Elsevier B.V. All rights reserved.

  3. Reduction of false positives in the detection of architectural distortion in mammograms by using a geometrically constrained phase portrait model

    Objective One of the commonly missed signs of breast cancer is architectural distortion. We have developed techniques for the detection of architectural distortion in mammograms, based on the analysis of oriented texture through the application of Gabor filters and a linear phase portrait model. In this paper, we propose constraining the shape of the general phase portrait model as a means to reduce the false-positive rate in the detection of architectural distortion. Material and methods The methods were tested with one set of 19 cases of architectural distortion and 41 normal mammograms, and with another set of 37 cases of architectural distortion. Results Sensitivity rates of 84% with 4.5 false positives per image and 81% with 10 false positives per image were obtained for the two sets of images. Conclusion The adoption of a constrained phase portrait model with a symmetric matrix and the incorporation of its condition number in the analysis resulted in a reduction in the false-positive rate in the detection of architectural distortion. The proposed techniques, dedicated for the detection and localization of architectural distortion, should lead to efficient detection of early signs of breast cancer. (orig.)

We showed that these genes were likely acquired from an O12 serotype strain that is closely related to P...... in clinical settings and outbreaks. These serotype O12 isolates exhibit high levels of resistance to various classes of antibiotics. Here, we explore how the P. aeruginosa OSA biosynthesis gene clusters evolve in the population by investigating the association between the phylogenetic relationships among 83 P....... aeruginosa strains and their serotypes.

    Events coupled with an emotional context seem to be better retained than non-emotional events. The aim of our study was to investigate whether an emotional context could influence the neural substrates of memory associations with novel portrait art stimuli. In the current prospective fMRI study, we have investigated for one specific visual art form (modern artistic portraits with a high degree of abstraction) whether memory is influenced by priming with emotional facial pictures. In total forty healthy female volunteers in the same age range were recruited for the study. Twenty of these women participated in a prospective brain imaging memory paradigm and were asked to memorize a series of similar looking, but different portraits. After randomization, for twelve participants (Group 1), a third of the portraits was emotionally primed with approach-related pictures (smiling baby faces), a third with withdrawal-related pictures (baby faces with severe dermatological conditions), and another third with neutral images. Group 2 consisted of eight participants and they were not primed. Then, during an fMRI session 2h later, these portraits were viewed in random order intermixed with a set of new (previously unseen) ones, and the participants had to decide for each portrait whether or not they had already been seen. In a separate experiment, a different sample of twenty healthy females (Group 3) rated their mood after being exposed to the same art stimuli, without priming. The portraits did not evoke significant mood changes by themselves, supporting their initial neutral emotional character (Group 3). The correct decision on whether the portraits were Familiar of Unfamiliar led to similar neuronal activations in brain areas implicated in visual and attention processing for both groups (Groups 1 and 2). In contrast, whereas primed participants showed significant higher neuronal activities in the left midline superior frontal cortex (Brodmann area (BA) 6), unprimed

    Egg quality is a complex biological trait and a major determinant of reproductive fitness in all animals. This study delivered the first proteomic portraits of egg quality in zebrafish, a leading biomedical model for early development. Egg batches of good and poor quality, evidenced by embryo survival for 24 h, were sampled immediately after spawning and used to create pooled or replicated sample sets whose protein extracts were subjected to different levels of fractionation before liquid chromatography and tandem mass spectrometry. Obtained spectra were searched against a zebrafish proteome database and detected proteins were annotated, categorized and quantified based on normalized spectral counts. Manually curated and automated enrichment analyses revealed poor quality eggs to be deficient of proteins involved in protein synthesis and energy and lipid metabolism, and of some vitellogenin products and lectins, and to have a surfeit of proteins involved in endo-lysosomal activities, autophagy, and apoptosis, and of some oncogene products, lectins and egg envelope proteins. Results of pathway and network analyses suggest that this aberrant proteomic profile results from failure of oocytes giving rise to poor quality eggs to properly transit through final maturation, and implicated Wnt signaling in the etiology of this defect. Quantitative comparisons of abundant proteins in good versus poor quality eggs revealed 17 candidate egg quality markers. Thus, the zebrafish egg proteome is clearly linked to embryo developmental potential, a phenomenon that begs further investigation to elucidate the root causes of poor egg quality, presently a serious and intractable problem in livestock and human reproductive medicine.

    Asteroids in mean motion resonances with giant planets are common in the solar system, but it was not until recently that several asteroids in retrograde mean motion resonances with Jupiter and Saturn were discovered. A retrograde co-orbital asteroid of Jupiter, 2015 BZ509 is confirmed to be in a long-term stable retrograde 1:1 mean motion resonance with Jupiter, which gives rise to our interests in its unique resonant dynamics. In this paper, we investigate the phase-space structure of the retrograde 1:1 resonance in detail within the framework of the circular restricted three-body problem. We construct a simple integrable approximation for the planar retrograde resonance using canonical contact transformation and numerically employ the averaging procedure in closed form. The phase portrait of the retrograde 1:1 resonance is depicted with the level curves of the averaged Hamiltonian. We thoroughly analyze all possible librations in the co-orbital region and uncover a new apocentric libration for the retrograde 1:1 resonance inside the planet’s orbit. We also observe the significant jumps in orbital elements for outer and inner apocentric librations, which are caused by close encounters with the perturber.

    Full Text Available The paper is focused on a sophisticated radio play by Tom Stoppard, In the Native State (1991, in which the dramatist approaches the problems linked to the ethics of the British Empire in dealing with Indian culture in both the colonial and post-colonial periods. To do this, the play confronts and complexly interlaces two different sets, India in the Thirties and London in 1990, as if they were two worlds reflecting themselves in a time mirror. The issues dealt with, such as the centuries-old westernization of the Indian minds and culture on one side, and the Indianization of British language and customs on the other, are subtlety treated in art terms, as the reciprocal relationship between the two worlds conflates in the hybrid style of the portraits executed by the hand of an Indian painter who, notwithstanding, or thanks to, his mimic identity (in Homi Bhabha’s terms, becomes the mouthpiece of a fundamental ‘change of perspective’, from the Eurocentric representation of the Orient (in Edward Said’s terms to the re-appropriation of a different point of view translating the achievement of the Nationalist movement that led India to independence in the Forties.

  12. Face Attractiveness versus Artistic Beauty in Art Portraits: A Behavioral Study

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available From art portraits, the observer may derive at least two different hedonic values: The attractiveness of the depicted person and the artistic beauty of the image that relates to the way of presentation. We argue that attractiveness is a property that is predominantly driven by perceptual processes, while the perception of artistic beauty is based predominantly on cognitive processing. To test this hypothesis, we conducted two behavioral experiments. In a gist study (Experiment 1, we showed that ratings on attractiveness were higher after short-term presentation (50 ms than after long-term presentation (3000 ms, while the opposite pattern was found for artistic beauty. In an experiment on perceptual contrast (Experiment 2, we showed that the perceptual contrast effect was stronger for attractiveness than for artistic beauty. These results are compatible with our hypothesis that appreciation of artistic beauty is cognitively modulated at least in part, while processing of attractiveness is predominantly driven perceptually. This dichotomy between cognitive and perceptual processing of different kinds of beauty suggests the participation of different neuronal mechanisms.

    The use of the pigment Egyptian blue is investigated on a corpus of fifteen mummy portraits and Roman-period paintings from Tebtunis, Egypt, housed in the Phoebe A. Hearst Museum of Anthropology at the University of California, Berkeley. Egyptian blue has a strong luminescence response in the near infrared that can be exploited to created wide-field images noninvasively showing the distribution of the pigment on a work of art. A growing body of publications in the last decade highlights the increasing use of this tool and its sensitive detection limits. However, the technique is not wavelength specific. Both excitation and emission occur in a broad range. Although Egyptian blue has a strong emission in the NIR, a myriad of other compounds may emit light in this spectral region when excited in the visible. The limited number of studies including complementary analysis to verify the presence of Egyptian blue does not allow its identification on the basis of NIR luminescence alone. Through the use of in situ X-ray fluorescence and X-ray diffraction, and scanning electron microscopy/energy-dispersive spectroscopy of cross sections, this paper confirms the identification of Egyptian blue by NIR luminescence in unexpected areas, i.e., those not blue in appearance.

    2012-06-01

    The biased positioning of faces exposed to viewers of Western portraiture has suggested there may be fundamental differences in the lateralized expression and perception of emotion. The present study investigates whether there are differences in the perception of the left and right sides of the face in real-life photographs of individuals. The study paired conscious aesthetic ratings of pleasantness with measurements of pupil size, which are thought to be a reliable unconscious measure of interest first tested by Hess. Images of 10 men and 10 women were taken from the left and right sides of the face. These images were also mirror-reversed. As expected, we found a strong preference for left-sided portraits (regardless of original or mirror-reversed orientation), such that left hemifaces elicited higher ratings and greater pupil dilation. Interestingly, this effect was true of both sexes. A positive linear relationship was also found between pupil size and aesthetic ratings such that pupil size increased with pleasantness ratings. These findings provide support for the notions of lateralized emotion, right-hemispheric dominance, pupillary dilation to pleasant images, and constriction to unpleasant images.

    Full Text Available The definition of the concept of relationship marketing is discussed. The notion of personal sale, which emphasizes the importance of knowing the psychology of customers, the ability to demonstrate significant competence and knowledge of modern techniques in sales by the seller is represented. The theory of marketing introduced by the concept of a "personal agent", most accurately reflects the activity of the seller in the context of relationship marketing. The necessity of the application of psychology in marketing is proved. This brief description of the four basic psychological concepts, which are the basis of the marketing strategy, is clarified by leading marketers. The three areas of application of differential psychology in marketing are suggested. The basis of the psychological techniques is represented by the typical characteristics of a person. The first point of the customer portrait is showed by the theory of spirits. The second point of psychological portrait is based on the theory of Socionics. The third point of the customer portrait refers to the theory of the types of perception of the world. Three stages of the process of building a psychological portrait of the client are proposed and described. Recommendations for dealing with clients of different psychological types are discussed. A technique of creation a psychological portrait of the client allows improving subjective well-being of customers and promotes the growth of the main indicators characterizing the effectiveness of personal sales.

    The aim of this article were to determinate the mechanism of linezolid resistance in coagulase-negative methicillin-resistant staphylococci from hospitals in the northeast of Brazil. We identified the isolates using VITEK(®) 2 and MALDI-TOF. Susceptibility to antibiotics was measured by the disk-diffusion method and by Etest(®) . Extraction of the whole genome DNA was performed, followed by screening of all the strains for the presence of mecA and cfr genes. The domain V region of 23S rRNA gene was sequenced and then aligned with a linezolid-susceptible reference strain. Pulsed-field gel electrophoresis (PFGE) macro-restriction analysis was performed. Three linezolid-resistant Staphylococcus hominis and two linezolid-resistant Staphylococcus epidermidis strains were analyzed. The isolates showed two point mutations in the V region of the 23S rRNA gene (C2190T and G2603T). We did not detect the cfr gene in any isolate by PCR. The S. hominis showed the same pulsotype, while the S. epidermidis did not present any genetic relation to each other. In conclusion, this study revealed three S. hominis and two S. epidermidis strains with resistance to linezolid due to a double mutation (C2190T and G2603T) in the domain V of the 23S rRNA gene. For the first time, the mutation of C2190T in S. epidermidis is described. This study also revealed the clonal spread of a S. hominis pulsotype between three public hospitals in the city of Natal, Brazil. These findings highlight the importance of continued vigilance of linezolid resistance in staphylococci. © 2015 APMIS. Published by John Wiley & Sons Ltd.

  19. ‘What is that to us? See to it yourself’ (Mt 27:4: Making atonement and the Matthean portrait of the Jewish chief priests

    Full Text Available To read the Gospel of Matthew within its 1st century religious context is to read an intensely Jewish narrative. Central to the world of this Gospel are the Jerusalem temple, its administrators, the chief priests, and the sacrificial system which they are charged by Jewish law to officiate. This article assesses the Matthean portrait of the Jewish chief priests of Jesus’ day against the scriptural backdrop which lays out their prominent role within Jewish religious life, namely ‘making atonement’ before God for the ‘sins’ of the people. In section one I sketch out the Matthean portrait of the scripturally assigned role of the priests, connecting this portrait to its biblical antecedents. In section two I assess the overall performance of the Matthean chief priests against the backdrop of their assigned role. In section three I address the question of atonement. Crucial here is 27:3–10, the account of Judas Iscariot, who returns his 30 silver coins to the chief priests and says (27:4a; emphasis mine, ‘I have sinned, because I have handed over innocent blood’. Here I highlight Matthew’s ironic modus operandi as he portrays the chief priests’ non-priestly response to Judas. Additionally, I contrast Matthew’s portrait of the Jewish chief priests with a brief portrait of Jesus’ own ministry within the Jewish community, a ministry which fulfils the priestly role abandoned by the chief priests. I conclude my article in section four with brief reflections on the rhetorical impact of Matthew’s portrait of the Jewish chief priests within his overall narrative.

  20. The Art of the Portrait in the Religious Painting of Wallachia and Moldavia in the 15th – 17th centuries

    Full Text Available Beyond the diversity of the forms of socio-economic and cultural-artistic development, at the end of the 14th century, Wallachia, Moldavia and the knights of Romanian origins of Transylvania, Banat and Maramureş were gathered in one single system, with feudality institutions of Occidental inspiration, but with mostly Orthodox spirituality, a system that is permanently struggling to find the perfect equilibrium between the Islamic-Ottoman expansionism and the insistent conversion actions of Western Catholicism. Medieval painting promoted the portrait as an artistic genre beyond the canonical constraints of the painting of Byzantine inspiration. The votive portrait of the founder did no necessarily reproduce the individual features of the portrayed person, not even in the last period, when the artistic and technical evolutions could initiate tendencies to a desacralization of the religious themes. The introduction of the portrait reflecting the social class in the Court of the two Romanian Countries through the Central – European sources of Austria, Hungary or Poland produced a major change in the aesthetics of the portrait when the artist came to have a new vision on the way he rendered the physical features and later the mental experiences of the model, sometimes making use of an obvious descriptive exactness in rendering the physical features, the physiognomy of the portrayed person. Just like in the medieval votive portrait, in the case of easel portraits, the artist focused on the representation of external features, according to the social importance and rank of the portrayed person. Gradually, the evolution of the corresponding capture of the physical features, initially sufficient, went up from a qualitative point of view to complete this first effort with a precious performance of the expression of the spiritual characteristics of the portrayed character, insistently claimed by both the artist and the contemplator.

    Full Text Available It is investigated the life and the pedagogical activity of Ukrainian historian, public and educational worker Mykola Volodymyrovych Storozhenko (1862-1942 in a whole, and the period of his directorship in 1909-1919 in the First Kyev’s gymnasium It is noted that as a historian Мykola Storozhenko was formed in the intellectual and cultural environment of the Kyiv documentary school of Volodymyr Antonovych, under whose direction he was successfully engaged in researching of the history of Ukraine; he was very familiar with many representatives of the Ukrainian scientific and public communities in the end of the XIX – at the beginning of the XX centuries; he was active in the Ukrainian community life as a member of the Kyiv Archaeographic Commission and the Historical Society of Nestor the Chronicler, as a member of journals «Kievan antiquity», «Historical Journal», «Russian Thought», a district activist in the Piryatinschina; he had a family origin from the old petty officers family, well-known since the XVII century. It is proved that the long-term Mykola Storozhenko educational and administrative activities contributed to the fact that he perfectly from the inside knew the system of existence and financing of the secondary education, the government policy of the Ministry of public education as an employee and the administrator, the urgent needs of gymnasiums and pedagogues. It is proved that Mykola Storozhenko occupies a worthy place among the cultural and educational figures of the end of the XIX – at the beginning of the XX centuries in Kyiv, whose activities influenced on the formation and education of Kyiv social and cultural environment, who generated a tradition of education and culture of the city, and were involved in the creation of an integrated socio-cultural portrait of pedagogues of Kyiv’s gymnasium of their time.

  2. Scrambled eggs: Proteomic portraits and novel biomarkers of egg quality in zebrafish (Danio rerio.

    Directory of Open Access Journals (Sweden)

    Ozlem Yilmaz

    Full Text Available Egg quality is a complex biological trait and a major determinant of reproductive fitness in all animals. This study delivered the first proteomic portraits of egg quality in zebrafish, a leading biomedical model for early development. Egg batches of good and poor quality, evidenced by embryo survival for 24 h, were sampled immediately after spawning and used to create pooled or replicated sample sets whose protein extracts were subjected to different levels of fractionation before liquid chromatography and tandem mass spectrometry. Obtained spectra were searched against a zebrafish proteome database and detected proteins were annotated, categorized and quantified based on normalized spectral counts. Manually curated and automated enrichment analyses revealed poor quality eggs to be deficient of proteins involved in protein synthesis and energy and lipid metabolism, and of some vitellogenin products and lectins, and to have a surfeit of proteins involved in endo-lysosomal activities, autophagy, and apoptosis, and of some oncogene products, lectins and egg envelope proteins. Results of pathway and network analyses suggest that this aberrant proteomic profile results from failure of oocytes giving rise to poor quality eggs to properly transit through final maturation, and implicated Wnt signaling in the etiology of this defect. Quantitative comparisons of abundant proteins in good versus poor quality eggs revealed 17 candidate egg quality markers. Thus, the zebrafish egg proteome is clearly linked to embryo developmental potential, a phenomenon that begs further investigation to elucidate the root causes of poor egg quality, presently a serious and intractable problem in livestock and human reproductive medicine.

  3. Measuring Values in Environmental Research: A Test of an Environmental Portrait Value Questionnaire

    Four human values are considered to underlie individuals’ environmental beliefs and behaviors: biospheric (i.e., concern for environment), altruistic (i.e., concern for others), egoistic (i.e., concern for personal resources) and hedonic values (i.e., concern for pleasure and comfort). These values are typically measured with an adapted and shortened version of the Schwartz Value Survey (SVS), to which we refer as the Environmental-SVS (E-SVS). Despite being well-validated, recent research has indicated some concerns about the SVS methodology (e.g., comprehensibility, self-presentation biases) and suggested an alternative method of measuring human values: The Portrait Value Questionnaire (PVQ). However, the PVQ has not yet been adapted and applied to measure values most relevant to understand environmental beliefs and behaviors. Therefore, we tested the Environmental-PVQ (E-PVQ) – a PVQ variant of E-SVS –and compared it with the E-SVS in two studies. Our findings provide strong support for the validity and reliability of both the E-SVS and E-PVQ. In addition, we find that respondents slightly preferred the E-PVQ over the E-SVS (Study 1). In general, both scales correlate similarly to environmental self-identity (Study 1), energy behaviors (Studies 1 and 2), pro-environmental personal norms, climate change beliefs and policy support (Study 2). Accordingly, both methodologies show highly similar results and seem well-suited for measuring human values underlying environmental behaviors and beliefs. PMID:29743874

    Meiotic recombination rate varies across the genome within and between individuals, populations, and species in virtually all taxa studied. In almost every species, this variation takes the form of discrete recombination hotspots, determined in some mammals by a protein called PRDM9. Hotspots and their determinants have a profound effect on the genomic landscape, and share certain features that extend across the tree of life. Drosophila, in contrast, are anomalous in their absence of hotspots, PRDM9, and other species-specific differences in the determination of recombination. To better understand the evolution of meiosis and general patterns of recombination across diverse taxa, we present a truly comprehensive portrait of recombination across time, combining recently published cross-based contemporary recombination estimates from each of two sister species with newly obtained linkage-disequilibrium-based historic estimates of recombination from both of these species. Using Drosophila pseudoobscura and Drosophila miranda as a model system, we compare recombination rate between species at multiple scales, and we suggest that Drosophila replicate the pattern seen in human–chimpanzee in which recombination rate is conserved at broad scales. We also find evidence of a species-wide recombination modifier(s), resulting in both a present and historic genome-wide elevation of recombination rates in D. miranda, and identify broad scale effects on recombination from the presence of an inversion. Finally, we reveal an unprecedented view of the distribution of recombination in D. pseudoobscura, illustrating patterns of linked selection and where recombination is taking place. Overall, by combining these estimation approaches, we highlight key similarities and differences in recombination between Drosophila and other organisms. PMID:26430062

  6. Hypothesis on a portrait of a girl of Severan age from Via Labicana (Rome

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available In 2007, during the archaeological excavations in via Labicana close to the church of SS. Pietro e Marcellino, a statue portraying a female head was unearthed: the piece appeared well-preserved and the formal characteristics suggested it had been sculpted under the Severian Dinasty. The Greek marble head by reason of the quality and style, can be compared with a series of portraits dating to the period between second and third decade of the III century A.D. It was possible to identify the head as that of Annia Aurelia Faustina by reason of the face and hair. She was the great niece of Marcus Aurelius and the third wife of emperor Eliogabalus, who was proclaimed Augusta from summer to winter in the year 221 A.D. Stratigraphic data proved uncertain, because in modern times, probably in the XVIIIth century, the head was thrown onto an earth dump, and the archaeological provenance is therefore uncertain being situated within an area where important monuments like the Isium Metellinum and the domus Tetricorum, are not yet placed with certainty. The excavations unearthed a cross-vaulted room with pillars and high skylights, maybe a horreum, that were laid upon previous structures constructed during Domitian’s reign, forming part of the earthworks on the northern side of Caelius hill. Later flights of stairs were built, to enable the room to link with the terrace and brick stamps were found, in part referring to the family of Marcus Aurelius and the Ummidia gens (in fact emperor’s sister, Annia Cornificia Faustina married Ummidius Quadratus, and in part to Commodus. It is suggested that after Ummidius’nephew had conspired in the plot against Commodus, the property formerly belonging to Cornificia was seized by the emperor himself but was later returned by Eliogabalus to his wife Annia Faustina, whom he honoured by commissioning the wonderful sculpture portrayed here.

    Full Text Available This paper explores the diversity and complexity of Rubens’s humanist interests and illustrates his appropriation of learned and esoteric knowledge, by discussing the anonymous painting in the Hermitage Museum in St. Petersburg in which Rubens is portrayed together with his son Albert. This portrait also depicts a sculpture from Rubens’s collection, that of Hecate Triformis, who in antiquity was considered to be a goddess of the underworld. By focusing on the books, manuscripts, Gnostic gems, and the Hecate statue from the artist’s collections, this paper will provide a new iconographic analysis of the Hermitage painting.

    Full Text Available Regeneration of injured nerves is likely occurring in the peripheral nervous system, but not in the central nervous system. Although protein-coding gene expression has been assessed during nerve regeneration, little is currently known about the role of non-coding RNAs (ncRNAs. This leaves open questions about the potential effects of ncRNAs at transcriptome level. Due to the limited availability of human neuropathic pain data, we have identified the most comprehensive time-course gene expression profile referred to sciatic nerve injury, and studied in a rat model, using two neuronal tissues, namely dorsal root ganglion (DRG and sciatic nerve (SN. We have developed a methodology to identify differentially expressed bioentities starting from microarray probes, and re-purposing them to annotate ncRNAs, while analyzing the expression profiles of protein-coding genes. The approach is designed to reuse microarray data and perform first profiling and then meta-analysis through three main steps. First, we used contextual analysis to identify what we considered putative or potential protein coding targets for selected ncRNAs. Relevance was therefore assigned to differential expression of neighbor protein-coding genes, with neighborhood defined by a fixed genomic distance from long or antisense ncRNA loci, and of parent genes associated with pseudogenes. Second, connectivity among putative targets was used to build networks, in turn useful to conduct inference at interactomic scale. Last, network paths were annotated to assess relevance to neuropathic pain. We found significant differential expression in long-intergenic ncRNAs (32 lincRNAs in SN, and 8 in DRG, antisense RNA (31 asRNA in SN, and 12 in DRG and pseudogenes (456 in SN, 56 in DRG. In particular, contextual analysis centered on pseudogenes revealed some targets with known association to neurodegeneration and/or neurogenesis processes. While modules of the olfactory receptors were clearly

    The idea of gerontogenes is in line with the evolutionary explanation of ageing as being an emergent phenomenon as a result of the imperfect maintenance and repair systems. Although evolutionary processes did not select for any specific ageing genes that restrict and determine the lifespan...... of an individual, the term ‘gerontogenes’ primarily refers to any genes that may seem to influence ageing and longevity, without being specifically selected for that role. Such genes can also be called ‘virtual gerontogenes’ by virtue of their indirect influence on the rate and process of ageing. More than 1000...... virtual gerontogenes have been associated with ageing and longevity in model organisms and humans. The ‘real’ genes, which do influence the essential lifespan of a species, and have been selected for in accordance with the evolutionary life history of the species, are known as the longevity assurance...

    2017-08-01

    Full Text Available Dickeya solani is an economically important phytopathogen widespread in mainland Europe that can reduce potato crop yields by 25%. There are no effective environmentally-acceptable chemical systems available for diseases caused by Dickeya. Bacteriophages have been suggested for use in biocontrol of this pathogen in the field, and limited field trials have been conducted. To date only a small number of bacteriophages capable of infecting D. solani have been isolated and characterized, and so there is a need to expand the repertoire of phages that may have potential utility in phage therapy strategies. Here we describe 67 bacteriophages from environmental sources, the majority of which are members of the viral family Myoviridae. Full genomic sequencing of two isolates revealed a high degree of DNA identity with D. solani bacteriophages isolated in Europe in the past 5 years, suggesting a wide ecological distribution of this phage family. Transduction experiments showed that the majority of the new environmental bacteriophages are capable of facilitating efficient horizontal gene transfer. The possible risk of unintentional transfer of virulence or antibiotic resistance genes between hosts susceptible to transducing phages cautions against their environmental use for biocontrol, until specific phages are fully tested for transduction capabilities.

    The genes encoding the glycoprotein VP7, the VP8* trypsin-cleavage product of the protein VP4, a fragment of the protein VP6 associated with subgroup (SG) specificity, and the enterotoxin NSP4 of rotavirus strains identified in diarrheic fecal samples of rabbits in Italy were sequenced. The Italian lapine rotavirus (LRV) strains possessed a G3 VP7, SG I VP6, and KUN-like NSP4, a gene constellation typical of LRVs. One LRV strain (30/96), isolated in 1996, shared the closest amino acid (aa) identity (87-96%) with the P[14] genotype, composed of human and LRV strains. Conversely, three LRV strains (160/01, 229/01, and 308/01), identified in 2001, were highly identical (90-95%) among each other, but showed low aa identity (34-77%) to the VP8* genotype-specific sequences of representative rotavirus strains of all remaining P genotypes. This report confirms the worldwide genetic constellations of LRVs and identifies a novel VP4 genotype in rabbits, tentatively proposed as genotype P[22

  16. Picturing continuity. The beginnings of the portrait gallery of Cracow bishops in the cloisters of the Franciscan friary in Cracow

    2017-12-01

    Full Text Available Important type of “group” portraits are likenesses of people connected by blood, holding the same position or representing the same office, shown next to one another, in chronological order. Such portrait galleries, which usually displayed a high degree of uniformity and disregarded the chronological and spatial accuracy, are examples of commemorative paintings. Their primary purpose was to emphasise the lineage and create a picture of unity by simultaneously showing, as a “family” and “house” people who lived in various times, but were united by heredity or succession. In the case of portraits of Catholic clergy, a key role is played by the notion of the Apostolic succession which has guaranteed the continuity in the Church since the times of Christ. The paper deals with (partially surviving group of likenesses of bishops, in the east and south wings of the cloister of the Franciscan friary in Cracow, initiated in the 1430s by Cardinal Zbigniew Oleśnicki, then ordinary bishop of Cracow, 1323–1455. The Franciscan collection likely showed all of Oleśnicki’s predecessors seated next to one another on stone benches, dressed in pontifical garb and identified by means of coats of arms. The founder of the gallery decided that his predecessors be depicted seated, a pose that was considered to be a privileged one, signified the authority of bishops and their role as teachers. The figures of enthroned bishops form a timeless, “ideal” congregation of hierarchs of the local ecclesiastical community. This particular, and fairly rare, arrangement of the representation may have been influenced by the fact that the portraits were painted on walls of cloister walks where, according to the monastic tradition, stone benches were often present. Zbigniew Oleśnicki was well-versed in history and there can be no doubt that he considered himself to be the heir to the accomplishments of all his predecessors and treated their group representation

  18. Fidelity analysis of mechanically aided copying/enlarging of Jan van Eyck's Portrait of Niccolo Albergati

    Stork, David G.; Duarte, Marco

    2007-01-01

    The contemporary artist David Hockney has hypothesized that some early Renaissance painters secretly projected optical images onto their supports (canvas, paper, oak panel, ...), directly traced these projections, and then filled in the tracings with paint[1]. Hockney has presented somewhat impressionistic image evidence for this claim, but he and thin-film physicist Charles Falco also point to perspective anomalies, to the fidelity of passages in certain paintings, and to historical documents in search of support for this direct tracing claim[2]. Key visual evidence adduced in support of this tracing claim is a pair of portraits by Jan van Eyck of Cardinal Niccolo Albergati - a small informal silverpoint study of 1431 and a slightly larger formal work in oil on panel of 1432. The contours in these two works bear striking resemblance in shape (after being appropriately scaled) and there are at least two "relative shifts" - passages that co-align well after a spatial shift of one of the images [2]. This evidence has led the theory's proponents to claim that van Eyck copied the silverpoint by means of an optical projector, or epidiascope, the relative shifts due to him accidentally bumping the setup during the copying. Previous tests of the tracing theory for these works considered four candidate methods van Eyck might have used to copied and enlarged the image in the silverpoint study: unaided ("by eye"), mechanical, grid, and the optical projection method itself [3]. Based on the full evidence, including the recent discovery of tiny pinprick holes in the silverpoint, reenactments, material culture and optical knowledge in the early 15th century, the mechanical method was judged most plausible and optical method the least plausible[3]. However, this earlier work did not adequately test whether a trained artist could "re-enact" the copying by mechanical methods: "Although we have not explicitly verified that high fidelities can be achieved through the use of a

    In the microevolutionary scales of Entamoeba isolates, the gene migration shows how Entamoeba spp. has epidemiologically drifted among border countries. Five hundred fecal samples were taken from patients suffering gastrointestinal disorders, abdominal pain, and diarrhea at Saggez, northwest Iran located within the border Iraq country. Following parasitological techniques, DNA samples were extracted and amplified by polymerase chain reaction (PCR) of 18S rRNA region to identify Entamoeba infections. To distinguish the Entamoeba spp., a multiplex PCR was conducted. Amplicons were sequenced to reconfirm their heterogeneity traits and phylogenetic analysis. Additionally, Entamoeba histolytica sequences of Iraq were retrieved from GenBank database. The suspected isolates were diagnosed as E. histolytica (2.2 %), Entamoeba moshkovskii (1 %), and Entamoeba dispar (0.4 %). Mixed Entamoeba infections did not detect among isolates. A parsimonious network of the sequence haplotypes displayed star-like features in the overall isolates containing E.h1, E.d2, and E.m3 as the most common haplotypes. According to analysis of molecular variance (AMOVA) test, high partial value of haplotype diversity (0.700 to 0.800) of E. histolytica was shown the total genetic variability within populations while nucleotide diversity was low among Iranian and Iraqi metapopulations. Neutrality indices of the 18S rRNA were shown negative values in E. histolytica populations which indicating significant deviations from neutrality.

    Designer molecules that can be used to impose exogenous control on gene transcription, artificial transcription factors (ATFs), are highly desirable as mechanistic probes of gene regulation, as potential therapeutic agents, and as components of cell-based devices. Recently, several advances have been made in the design of ATFs that activate gene transcription (activator ATFs), including reports of small-molecule-based systems and ATFs that exhibit potent activity. However, the many open mechanistic questions about transcriptional activators, in particular, the structure and function of the transcriptional activation domain (TAD), have hindered rapid development of synthetic ATFs. A compelling need thus exists for chemical tools and insights toward a more detailed portrait of the dynamic process of gene activation.

    In 1996 the Nuclear Regulatory Authority of the Slovak Republic (NRA SR) continued in systematic development of its activities in the field of emergency planning according to the concept adopted by the Authority and according to the concept for building Emergency headquarters (EH) adopted after establishing of Emergency Response Centre (ERC). Major efforts were focused not only on building up a quality EH, but also tasks associated with completion and incorporation of ERC into emergency planning and emergency managing. An important role in building ERC was played by international missions. Significant position among these missions was taken by missions from Great Britain, which in the past years made a significant contribution to building up ERC. These missions focused on review of newly created standard procedures, preparation and implementation of first emergency exercises of the EH. The emergency exercises in which NRA SR took place in 1996 are reviewed. In order to make the co-operation of the Authority with the selected Army units of SR more effective in solving extraordinary situations in nuclear energy, an agreement was signed between NRA SR and the Headquarters of the Army of SR, which will help significantly to the objective

    Increased reactivity to stress is observed in patients with schizophrenia spectrum disorders and their healthy siblings in comparison with the general population. Additionally, higher levels of neuroticism, as a proposed psychological measure of stress sensitivity, increase the risk of schizophrenia. HPA axis dysregulation is one of the possible mechanisms related to the vulnerability-stress model of schizophrenia, and recent studies revealed a possible role of the functional genetic variants of FK506-binding protein 51 (FKBP5) gene which modulate activity of HPA axis. The purpose of the present study was to investigate impact of FKBP5 on schizophrenia in Serbian patients and to explore relationship between genetic variants and neuroticism by using the case-sibling-control design. In 158 subjects, we measured psychotic experiences, childhood trauma and neuroticism. Nine single-nucleotide polymorphisms (rs9295158, rs3800373, rs9740080, rs737054, rs6926133, rs9380529, rs9394314, rs2766533 and rs12200498) were genotyped. The genetic influence was modeled using logistic regression, and the relationship between genetic variants and neuroticism was assessed by linear mixed model. Our results revealed genetic main effect of FKBP5 risk alleles (A allele of rs9296158 and T allele of rs3800373) and AGTC "risk" haplotype combination (rs9296158, rs3800373, rs9470080 and rs737054, respectively) on schizophrenia, particularly when childhood trauma was set as a confounding factor. We confirmed strong relationship between neuroticism and psychotic experiences in patients and siblings and further showed relationship between higher levels of neuroticism and FKBP5 risk variants suggesting potential link between biological and psychosocial risk factors. Our data support previous findings that trauma exposure shapes FKBP5 impact on schizophrenia.

    Historians of medicine--and even Louis Pasteur's biographers--have paid little attention to his close relationship with the Finnish artist Albert Edelfelt. A new look at Edelfelt's letters to his mother, written in Swedish and never quoted at length in English, reveals important aspects of Pasteur's working habits and personality. By understanding the active collaboration through which this very famous portrait was made, we also discover unnoticed things in the painting itself, gain a new appreciation of its original impact on the French public's image of science, and better understand its enduring influence on the portrayal of medicine in the art and the popular culture of many countries even to the present day.

    Emergence refers to the unique human ability to aggregate information from seemingly meaningless pieces, and to perceive a whole that is meaningful. This special skill of humans can constitute an effective scheme to tell humans and machines apart. This paper presents a synthesis technique to generate images of 3D objects that are detectable by humans, but difficult for an automatic algorithm to recognize. The technique allows generating an infinite number of images with emerging figures. Our algorithm is designed so that locally the synthesized images divulge little useful information or cues to assist any segmentation or recognition procedure. Therefore, as we demonstrate, computer vision algorithms are incapable of effectively processing such images. However, when a human observer is presented with an emergence image, synthesized using an object she is familiar with, the figure emerges when observed as a whole. We can control the difficulty level of perceiving the emergence effect through a limited set of parameters. A procedure that synthesizes emergence images can be an effective tool for exploring and understanding the factors affecting computer vision techniques. © 2009 ACM.

    2016-01-01

    Anorectal emergencies refer to anorectal disorders presenting with some alarming symptoms such as acute anal pain and bleeding which might require an immediate management. This article deals with the diagnosis and management of common anorectal emergencies such as acutely thrombosed external hemorrhoid, thrombosed or strangulated internal hemorrhoid, bleeding hemorrhoid, bleeding anorectal varices, anal fissure, irreducible or strangulated rectal prolapse, anorectal abscess, perineal necrotizing fasciitis (Fournier gangrene), retained anorectal foreign bodies and obstructing rectal cancer. Sexually transmitted diseases as anorectal non-surgical emergencies and some anorectal emergencies in neonates are also discussed. The last part of this review dedicates to the management of early complications following common anorectal procedures that may present as an emergency including acute urinary retention, bleeding, fecal impaction and anorectal sepsis. Although many of anorectal disorders presenting in an emergency setting are not life-threatening and may be successfully treated in an outpatient clinic, an accurate diagnosis and proper management remains a challenging problem for clinicians. A detailed history taking and a careful physical examination, including digital rectal examination and anoscopy, is essential for correct diagnosis and plan of treatment. In some cases, some imaging examinations, such as endoanal ultrasonography and computerized tomography scan of whole abdomen, are required. If in doubt, the attending physicians should not hesitate to consult an expert e.g., colorectal surgeon about the diagnosis, proper management and appropriate follow-up. PMID:27468181

    Full Text Available In recent years, the surprising progress made in other areas of hematology (advances in the understanding of leukemogenesis, improved transplant techniques has been conspicuously absent in the management of hematologic emergencies. And yet, every step toward greater knowledge, every new treatment option will be of little value unless we are able to manage the acute complications of hematologic diseases. These complications are better defined as hematologic emergencies, and they are characterized by a high rate of mortality. This review is based on a search of the literature that was initially confined to articles published in the journal Hematology from 2000 to 2009. The search was then extended to the Cochrane Library and to Pub Med in February 2010 with the following Keywords emergencies; urgencies; hematology. The same key words were employed in a search of the archives of Blood and the New England Journal of Medicine from 2000 to 2010. The results confirm that hematologic emergencies can be caused by hematologic malignancies as well as by non-neoplastic hematologic diseases. Within the former category; this review examines the causes; manifestations; treatment and prevention of disseminated intravascular coagulation; superior vena caval syndrome; spinal cord compression; tumor lysis syndrome; hyperleukocytosis; and hypercalcemia. We also review emergency situations associated with non-neoplatic haematological diseases; such as thrombotic thrombocytopenic purpura; drug-induced hemolytic anemia; and acute sickle-cell crisis.

    On September 19th 2008, a technical fault was at the centre of a sequence of events which hampered the performance of certain equipments of the LHC 3-4 sector. Once the first effects of this sequence of events were detected, the behaviour of the CERN staff confronted to this complex and critical situation became the centre of the risk control process. During such a downward spiral the preparation of all stakeholders is essential and should respect the (apparently) basic principles of emergency preparedness. Preparedness towards normal operation of CERN facilities towards minor up to major emergency situations will be presented. The main technical, organisational and legal frameworks of the CERN emergency preparedness will be recalled, highlighting the CERN risk management and risk control strategy. Then, the sequence of events experienced by different stakeholders on September 19th will be reported, thus starting the learned lessons process.

    The nuclear activities are exercised so as to prevent the accidents. They are subjected to a rule whom application is controlled by the Asn. The risk of grave accident is so limited to a very low level of probability. He cannot be however completely pushed aside. The expression ' radiological emergency situation ' indicates a situation which ensues from an incident or of an accident risking to lead to an emission of radioactive materials or a level of radioactivity susceptible to strike a blow at the public health. The term ' nuclear crisis ' is used for the events which can lead to a radiological emergency situation on a nuclear basic installation or during a transport of radioactive materials. The preparation and the management of emergency situations, that they are of natural, accidental or terrorist origin, became a major concern of our society. We propose you of to know more about it in this file. (N.C.)

It aims at providing exhaustive information that will help the reader understand the clinical problems in the full range of neurological emergencies and to select the methodological and technical options that will ensure prompt and effective response and correct interpretation of the clinical findings. The various chapters address the most common neuroradiological emergencies, summarize their fundamental physiopathological features, describe the main semiological and differential diagnostic features, and provide operative suggestions for the selection of the appropriate techniques to be applied in a sequential order. The book addresses the application of state-of-the-art techniques and their implications for clinical practice (particularly the contributions of standard and functional MRI and of spiral and multislice CT). The illustrations provide not only training but also reference material for routine clinical work. (orig.)

    2018-04-01

    This mini-review is devoted to the problem genetic meaning of main polytene chromosome structures - bands and interbands. Generally, densely packed chromatin forms black bands, moderately condensed regions form grey loose bands, whereas decondensed regions of the genome appear as interbands. Recent progress in the annotation of the Drosophila genome and epigenome has made it possible to compare the banding pattern and the structural organization of genes, as well as their activity. This was greatly aided by our ability to establish the borders of bands and interbands on the physical map, which allowed to perform comprehensive side-by-side comparisons of cytology, genetic and epigenetic maps and to uncover the association between the morphological structures and the functional domains of the genome. These studies largely conclude that interbands 5'-ends of housekeeping genes that are active across all cell types. Interbands are enriched with proteins involved in transcription and nucleosome remodeling, as well as with active histone modifications. Notably, most of the replication origins map to interband regions. As for grey loose bands adjacent to interbands, they typically host the bodies of house-keeping genes. Thus, the bipartite structure composed of an interband and an adjacent grey band functions as a standalone genetic unit. Finally, black bands harbor tissue-specific genes with narrow temporal and tissue expression profiles. Thus, the uniform and permanent activity of interbands combined with the inactivity of genes in bands forms the basis of the universal banding pattern observed in various Drosophila tissues.

    Full Text Available Emergency contraception refers to any device or drug that is used as an emergency procedure to prevent pregnancy after unprotected sexual intercourse.The first method of emergency contraception was high dose of estrogen. Concern about side effects led to subsequent development of the so-called Yuzpe regimen which combined ethinil estradiol with levonorgestrel and levonorgestrel alone. Less convenient to use is the copper intauterine contraceptive device.It is known that in some women sexual steroids may inhibit or delay ovulation and may interfere with ovum and sperm transport and implantation. Copper intrauterine device causes a foreign-body effect on the endometrium and a direct toxic effect to sperm and blastocyst.The Yuzpe regimen reduces the risk of pregnancy after a single act of sexual intercourse by about 75% and the levonorgestrel alone by about 85%. The copper intrauterine device is an extremely effective method for selected patients.Nausea and vomiting are common among women using the Yuzpe regimen and considerably less common among women using levonorgestrel alone regimen.Emergency contraception is relatively safe with no contraindications except pregnancy. It is ineffective if a woman is pregnant. There is no need for a medical hystory or a phisical examination before providing emergency contraceptive pills. They are taken long before organogenesis starts, so they should not have a teratogenic effect.Counseling should include information about correct use of the method, possible side effects and her preferences for regular contraception.Unintended pregnancy is a great problem. Several safe, effective and inexpensive methods of emergency contraception are available including Yuzpe regimen, levonorges-trel-only regimen and copper intrauterine device.

    Mediator is a multi-subunit protein complex that regulates gene expression in eukaryotes by integrating physiological and developmental signals and transmitting them to the general RNA polymerase II machinery. We examined, in the fungal pathogen Candida albicans, a set of conditional alleles of genes encoding Mediator subunits of the head, middle, and tail modules that were found to be essential in the related ascomycete Saccharomyces cerevisiae. Intriguingly, while the Med4, 8, 10, 11, 14, 17, 21 and 22 subunits were essential in both fungi, the structurally highly conserved Med7 subunit was apparently non-essential in C. albicans. While loss of CaMed7 did not lead to loss of viability under normal growth conditions, it dramatically influenced the pathogen's ability to grow in different carbon sources, to form hyphae and biofilms, and to colonize the gastrointestinal tracts of mice. We used epitope tagging and location profiling of the Med7 subunit to examine the distribution of the DNA sites bound by Mediator during growth in either the yeast or the hyphal form, two distinct morphologies characterized by different transcription profiles. We observed a core set of 200 genes bound by Med7 under both conditions; this core set is expanded moderately during yeast growth, but is expanded considerably during hyphal growth, supporting the idea that Mediator binding correlates with changes in transcriptional activity and that this binding is condition specific. Med7 bound not only in the promoter regions of active genes but also within coding regions and at the 3' ends of genes. By combining genome-wide location profiling, expression analyses and phenotyping, we have identified different Med7p-influenced regulons including genes related to glycolysis and the Filamentous Growth Regulator family. In the absence of Med7, the ribosomal regulon is de-repressed, suggesting Med7 is involved in central aspects of growth control.

    Full Text Available Abstract Background Uncovering the molecular mechanisms involved in epileptogenesis is critical to better understand the physiopathology of epilepsies and to help develop new therapeutic strategies for this prevalent and severe neurological condition that affects millions of people worldwide. Results Changes in the transcriptome of hippocampal cells from rats subjected to the pilocarpine model of epilepsy were evaluated by microarrays covering 34,000 transcripts representing all annotated rat genes to date. Using such genome-wide approach, differential expression of nearly 1,400 genes was detected during the course of epileptogenesis, from the early events post status epilepticus (SE to the onset of recurrent spontaneous seizures. Most of these genes are novel and displayed an up-regulation after SE. Noteworthy, a group of 128 genes was found consistently hyper-expressed throughout epileptogenesis, indicating stable modulation of the p38MAPK, Jak-STAT, PI3K, and mTOR signaling pathways. In particular, up-regulation of genes from the TGF-beta and IGF-1 signaling pathways, with opposite effects on neurogenesis, correlate with the physiopathological changes reported in humans. Conclusions A consistent regulation of genes functioning in intracellular signal transduction regulating neurogenesis have been identified during epileptogenesis, some of which with parallel expression patterns reported in patients with epilepsy, strengthening the link between these processes and development of epilepsy. These findings reveal dynamic molecular changes occurring in the hippocampus that may serve as a starting point for designing alternative therapeutic strategies to prevent the development of epilepsy after acquired brain insults.

    Full Text Available Emergency post-coital contraception (EC is an effective method of preventing pregnancy when used appropriately. EC has been available since the 1970s, and its availability and use have become widespread. Options for EC are broad and include the copper intrauterine device (IUD and emergency contraceptive pills such as levonorgestrel, ulipristal acetate, combined oral contraceptive pills (Yuzpe method, and less commonly, mifepristone. Some options are available over-the-counter, while others require provider prescription or placement. There are no absolute contraindications to the use of emergency contraceptive pills, with the exception of ulipristal acetate and mifepristone. This article reviews the mechanisms of action, efficacy, safety, side effects, clinical considerations, and patient preferences with respect to EC usage. The decision of which regimen to use is influenced by local availability, cost, and patient preference.

    1996-01-01

    In 1995, major efforts of the Nuclear Regulatory Authority of the Slovak Republic (NRA SR) were focused on tasks associated with completion and incorporation of the Emergency Response Centre (ERC) of NRA SR in emergency planning and crisis management. Construction of the ERC had begun based on NRA SR's knowledge, as well as recommendations of Regulatory Assistance Management Group (RAMG) International Mission in 1993 and follow-up missions in 1994. Early in 1994, re-construction of selected rooms had been done and early in 1995, supported by the UK and U.S.A. Government's funding, technical equipment was purchased. The equipment was necessary for ERC operation as tools to improve NRA SR readiness for the management of emergency situations at nuclear installations. NRA SR commenced operation of the Centre in April 1995. The Centre has been on-line connected to a teledosimetric system of Radiation Monitoring Laboratory in Trnava. The basic software for assessment of radiation consequences of a NPP accident was supplied were also focused on cooperation with state administration authorities and organizations which were involved in an emergency planning structure. In September 1995, staffing of the ERC was completed and parallel, the first document concerning the ERC prime task, i.e. activities and procedures of of NRA SR Crisis crew in case of an accident at a nuclear installation on the territory of the Slovak Republic, was approved by the NRA SR's Management. In the period that is being assessed, NRA SR made significant progress in events classification and emergency planning terminology in order to unify the above between both the Slovak NPPs

  18. Historical Painting and Portraits of Independence Heroes in Colombia during the Nineteenth Century: Lack of Public Support and Importance of Private Initiatives

    Full Text Available In this article we study historical painting and portraits of founding fathers and independence heroes produced in Colombia during the 19th century. These paintings have usually been analyzed from iconographic and iconological perspectives; however, they are presented here as cultural objects that undergo specific production, diffusion, reception and appropriation processes. To shine some light on these topics, we examined different document collections from the General Archive of the Nation (Colombia and the Historical Archive of the National Museum (Colombia, as well as the press and legislation of the time. It was found that the minimal state support of pictorial production would have discouraged the elaboration of historical paintings in Colombia. We discovered that although portrait painting was occasionally encouraged by the Government throughout the 19th century, most of the portraits were the result of private initiatives. This situation, however, didn’t prevent their exhibition in public spaces and an increase in their circulation. In conclusion, the absence of wide ranging projects for an official production of that type of paintings leads us to relativize the role of representation in the creation of Colombia’s national narrative, particularly in the National Museum.

    Full Text Available Abstract Background Validation of a novel gene expression signature in independent data sets is a critical step in the development of a clinically useful test for cancer patient risk-stratification. However, validation is often unconvincing because the size of the test set is typically small. To overcome this problem we used publicly available breast cancer gene expression data sets and a novel approach to data fusion, in order to validate a new breast tumor intrinsic list. Results A 105-tumor training set containing 26 sample pairs was used to derive a new breast tumor intrinsic gene list. This intrinsic list contained 1300 genes and a proliferation signature that was not present in previous breast intrinsic gene sets. We tested this list as a survival predictor on a data set of 311 tumors compiled from three independent microarray studies that were fused into a single data set using Distance Weighted Discrimination. When the new intrinsic gene set was used to hierarchically cluster this combined test set, tumors were grouped into LumA, LumB, Basal-like, HER2+/ER-, and Normal Breast-like tumor subtypes that we demonstrated in previous datasets. These subtypes were associated with significant differences in Relapse-Free and Overall Survival. Multivariate Cox analysis of the combined test set showed that the intrinsic subtype classifications added significant prognostic information that was independent of standard clinical predictors. From the combined test set, we developed an objective and unchanging classifier based upon five intrinsic subtype mean expression profiles (i.e. centroids, which is designed for single sample predictions (SSP. The SSP approach was applied to two additional independent data sets and consistently predicted survival in both systemically treated and untreated patient groups. Conclusion This study validates the "breast tumor intrinsic" subtype classification as an objective means of tumor classification that should be

    The ideal reference, or control, gene for the study of gene expression in a given organism should be expressed at a medium‑high level for easy detection, should be expressed at a constant/stable level throughout different cell types and within the same cell type undergoing different treatments, and should maintain these features through as many different tissues of the organism. From a biological point of view, these theoretical requirements of an ideal reference gene appear to be best suited to housekeeping (HK) genes. Recent advancements in the quality and completeness of human expression microarray data and in their statistical analysis may provide new clues toward the quantitative standardization of human gene expression studies in biology and medicine, both cross‑ and within‑tissue. The systematic approach used by the present study is based on the Transcriptome Mapper tool and exploits the automated reassignment of probes to corresponding genes, intra‑ and inter‑sample normalization, elaboration and representation of gene expression values in linear form within an indexed and searchable database with a graphical interface recording quantitative levels of expression, expression variability and cross‑tissue width of expression for more than 31,000 transcripts. The present study conducted a meta‑analysis of a pool of 646 expression profile data sets from 54 different human tissues and identified actin γ 1 as the HK gene that best fits the combination of all the traditional criteria to be used as a reference gene for general use; two ribosomal protein genes, RPS18 and RPS27, and one aquaporin gene, POM121 transmembrane nucleporin C, were also identified. The present study provided a list of tissue‑ and organ‑specific genes that may be most suited for the following individual tissues/organs: Adipose tissue, bone marrow, brain, heart, kidney, liver, lung, ovary, skeletal muscle and testis; and also provides in these cases a representative

    Full Text Available Cet article analyse l’incidence des modes de circulation de l’image sur les pratiques de la photographie de presse. L’exemple choisi est celui d’une photographie qui représente une femme au milieu des décombres d’Ishinomaki, image achetée par l’Agence France-Presse (AFP à un quotidien japonais, au lendemain du Tsunami de mars 2011. Reprise en couverture de nombreux journaux occidentaux, recadrée autour de la figure féminine, initialement saisie en plan large, cette photographie devient un portrait, rapidement désigné comme « la madone des décombres ». En décrivant les facteurs techniques, commerciaux et éditoriaux qui structurent le secteur de la photographie de presse, l’article interroge la mondialisation des standards visuels. Il s’agit de comprendre comment des phénomènes de stéréotypie visuelle apparaissent en lien avec le fonctionnement du marché de l’image numérique : l’auteur procède donc à une observation des logiciels utilisés par les journalistes de l’AFP, combinée à une analyse sémiotique des formats, légendes, commentaires sur l’image. Il apparaît que la mondialisation de la photographie de presse, qui repose sur des « syndications » internationales, modifie aussi le statut du photographe d’agence. Alors que les normes journalistiques pour le journalisme agencier préconisent l’effacement de l’auteur, les transformations de la photographie d’Ishinomaki sont le déclenchement d’un feuilleton médiatique, sur les réseaux sociaux comme dans les magazines occidentaux, dont le photographe lui-même devient le héros. L’AFP publie une semaine après le Tsunami une dépêche concernant l’histoire de cette image, dévoilant toutes sortes d’informations qui demeurent ordinairement inconnues du public : prix de vente de la photographie, nom du chef du bureau chargé de la collecte d’informations en Asie, identité du photographe.

    South Korean and Taiwanese brands have long been household names. Today, however, the names of transnational companies (TNCs) from an increasingly diverse set of emerging and developing economies are regularly making if not the dinner table conversation then at least the headlines...... of the international business press. This reflects that companies such as Mittal and Tata (India), China National Offshore Oil Corporation (CNOOC), Haier and Lenovo (PRC), Embraer (Brazil), SAPMiller (South Africa), and Cemex (Mexico) are foraying ever deeper into the international economy and increasingly investing...... countries. Apart from a few early pioneering studies (Lecraw 1977; Lall 1983; Wells 1983; Agarwal 1985) only few studies have been made so far of outward investment from emerging and developing economies. This is in spite of the fact that the value of outward FDI stock from developing countries reached USD...

    In this work, we propose a novel search strategy for new physics at the LHC that utilizes calorimeter jets that (i) are composed dominantly of displaced tracks and (ii) have many different vertices within the jet cone. Such emerging jet signatures are smoking guns for models with a composite dark sector where a parton shower in the dark sector is followed by displaced decays of dark pions back to SM jets. No current LHC searches are sensitive to this type of phenomenology. We perform a detailed simulation for a benchmark signal with two regular and two emerging jets, and present and implement strategies to suppress QCD backgrounds by up to six orders of magnitude. At the 14 TeV LHC, this signature can be probed with mediator masses as large as 1.5 TeV for a range of dark pion lifetimes, and the reach is increased further at the high-luminosity LHC. The emerging jet search is also sensitive to a broad class of long-lived phenomena, and we show this for a supersymmetric model with R-parity violation. Possibilit...

    According the conception of the Emergency Response Centre (ERC) of the Nuclear Regulatory Authority of the Slovak Republic (NRA), and the obtained experience from exercises, and as well as on the basis of recommendations of international missions, the NRA SR started, in 1997 the ERC extension. The new room enable the work for radiation protection group, reactor safety and logistic group separately. At the same time special room was build for work of the NECRA Technical Support Group of the Emergency Commission for Radiation Accidents of the SR.This group co-operates closely with ERC while evaluation the situation, and by using the information system of the NRA and database of ERC to generate the conditions of nuclear facilities in once of emergency. Extension of the mentioned rooms was carried out. The financing by the European Union helped to build the project RAMG. In this way the NRA gained a working site which, with its equipment and parameters belongs to the top working sites of regulatory bodies of developed European countries. The NRA preparation of exercise and special staff education was carried out in 1997, for employees of the NRA and members of Emergency Headquarters (EH) for work in ERC in case of nuclear installation accident. The task of education of member of EH was their preparation for carrying out three exercises. These exercises are described. In the area of emergency preparedness, in accordance with inspection plan of the Office, 7 team inspections were carried out in individual localities; in NPP Bohunice, two in NPP Mochovce and one in Bohunice Conditioning Centre for radioactive wastes. Solution of the task of development of science and technology in the area of 'Development of technical and programme means for analyses of accidents and solutions of crisis situations'continued in 1997. Another regulations were elaborated for activity of members of EH of the NRA. The following was was carried out: selection of data for transfer and the

    Full Text Available Neuroinflammatory processes are recognized key contributory factors in Parkinson's disease (PD physiopathology. While the causes responsible for the progressive loss of midbrain dopaminergic (mDA neuronal cell bodies in the subtantia nigra pars compacta are poorly understood, aging, genetics, environmental toxicity, and particularly inflammation, represent prominent etiological factors in PD development. Especially, reactive astrocytes, microglial cells, and infiltrating monocyte-derived macrophages play dual beneficial/harmful effects, via a panel of pro- or anti-inflammatory cytokines, chemokines, neurotrophic and neurogenic transcription factors. Notably, with age, microglia may adopt a potent neurotoxic, pro-inflammatory “primed” (M1 phenotype when challenged with inflammatory or neurotoxic stimuli that hamper brain's own restorative potential and inhibit endogenous neurorepair mechanisms. In the last decade we have provided evidence for a major role of microglial crosstalk with astrocytes, mDA neurons and neural stem progenitor cells (NSCs in the MPTP- (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine- mouse model of PD, and identified Wnt/β-catenin signaling, a pivotal morphogen for mDA neurodevelopment, neuroprotection, and neuroinflammatory modulation, as a critical actor in glia-neuron and glia-NSCs crosstalk. With age however, Wnt signaling and glia-NSC-neuron crosstalk become dysfunctional with harmful consequences for mDA neuron plasticity and repair. These findings are of importance given the deregulation of Wnt signaling in PD and the emerging link between most PD related genes, Wnt signaling and inflammation. Especially, in light of the expanding field of microRNAs and inflammatory PD-related genes as modulators of microglial-proinflammatory status, uncovering the complex molecular circuitry linking PD and neuroinflammation will permit the identification of new druggable targets for the cure of the disease. Here we summarize

    The objective of this article is to provide a portrait of prefrontal lobotomy performed at the Royal Prince Alfred Hospital, Sydney by the Head of Neurosurgery Dr Rex Money and to describe Dr Money's role in the promotion of psychosurgery in Sydney. We draw attention to an oral presentation by Dr Rex Money in 1951, a journal article written by Money, archival information held at the Royal Prince Alfred Hospital, including Dr Money's accounts of his travels and his reports regarding neurosurgery - both internationally and in Australia. Dr Rex Money performed a series of 13 prefrontal lobotomies between 1945 and 1951, and presented the theoretical basis for his series, his operative procedures and the outcomes at the annual meeting of its medical officers' association. Notwithstanding various deficiencies in his clinical research, Money's descriptions give a relatively comprehensive account of one of the first series of prefrontal lobotomies performed in Australia. The current article also describes Dr Money's contributions to the promotion of psychosurgery in Sydney, and illustrates the participation of a senior neurosurgeon and of a major Sydney teaching hospital during the psychosurgery saga. © The Royal Australian and New Zealand College of Psychiatrists 2016.

    Despite the burgeoning scientific literature examining the sluggish cognitive tempo (SCT) construct, very little is known about the clinical presentation of SCT. In clinical cases where SCT is suspected, it is critical to carefully assess not only for attention-deficit/hyperactivity disorder (ADHD) but also for other comorbidities that may account for the SCT-related behaviors, especially internalizing symptoms and sleep problems. The current case study provides a clinical description of SCT in a 7-year-old girl, offering a real-life portrait of SCT while also providing an opportunity to qualitatively differentiate between SCT and ADHD, other psychopathologies (e.g. depression, anxiety), and potentially related domains of functioning (e.g. sleep, executive functioning [EF]). "Jessica" was described by herself, parents, and teacher as being much slower than her peers in completing schoolwork, despite standardized testing showing Jessica to have above average intelligence and academic achievement. Jessica's parents completed rating scales indicating high levels of SCT symptoms and daytime sleepiness, as well as mildly elevated EF deficits. More research is needed to determine how to best conceptualize, assess, and treat SCT, and Jessica's case underscores the importance of further work in this area. © The Author(s) 2014.

    Full text: There are numerous conditions that affect mainly or exclusively the pediatric population. These constitute true emergencies, related to patient's health. Delay in diagnosis and treatment of abdominal non-traumatic emergencies may result in rapid deterioration, peritonitis, sepsis, even death or in severe complications with subsequent morbidity. Abdominal emergencies in children mostly present with pain, tenderness, occasionally coupled by vomiting, fever, abdominal distension, and failure to pass meconium or stools. Diarrhea, blood per rectum, abnormal laboratory tests and lethargy may also be manifestations of acute abdominal conditions. Abdominal emergencies have a different aetiology, depending on age and whether the pain is acute or chronic. Symptoms have to be matched with age and gender. Newborns up to 1 months of age may have congenital diseases: atresia, low obstruction including Hirschsprung's disease, meconium ileus. Meconium plug is one of the commonest cause of low obstruction in newborns that may also develop necrotizing enterocolitis, incarcerated inguinal hernia and mid-gut volvulus. Past the immediate postnatal period, any duodenal obstruction should be considered midgut volvulus until proven otherwise and patients should undergo ultrasonography and/or properly performed upper GI contrast study that records the exact position of the deduno-jejunal junction. Infants 6 months-2 years carry the risk of intussusception, mid-gut volvulus, perforation, acute pyelonephritis. Preschool and school-aged children 2-12 years carry the risk of appendicitis, genito-urinary abnormalities including torsion, urachal abnormalities, haemolytic uremic syndrome and Henoch-Schonlein purpura. Children above 12 years suffer from the same conditions as in adults. Most conditions may affect any age despite age predilection.

    2014-08-01

    Building on findings that self-uncertainty motivates attempts to restore certainty about the self, particularly in ways that highlight one's distinctiveness from others, we show that self-uncertainty, relative to uncertainty in general, increases creative generation among individualists. In Studies 1 to 3, high (but not low) individualists performed better on a creative generation task after being primed with self-uncertainty as opposed to general uncertainty. In Study 4, this effect emerged only among those who were told that the task measured creative as opposed to analytical thinking, suggesting that the positive effects of self-uncertainty on performance are specific to tasks that bolster perceptions of uniqueness. In Study 5, self-uncertain individualists experienced a restoration of self-clarity after being induced to think about themselves as more (vs. less) creative. Implications for compensatory responses to self-uncertainty and factors that influence creativity are discussed. © 2014 by the Society for Personality and Social Psychology, Inc.

    While the past decades were marked by an increased interest for the existential situation of man suffering from disease, the mechanisms alienating the patient from himself and from his context have been poorly investigated. These mechanisms, though operating in a dynamic interaction, will be discussed here sequentially. The first part of this article focuses on individual mechanisms of alienation emerging from the relationship the patient establishes with his body and psyche and on those related to his relational context. The aim is not to comprehensively describe these phenomena, but to discuss--based on clinical vignettes--some examples and their implications. The second part of the article describes some mechanisms of alienation that are incorporated in the medical apparatus and the dominant discourses.

    Full Text Available We report a study of genome-wide, dense SNP (∼ 900K and copy number polymorphism data of indigenous southern Africans. We demonstrate the genetic contribution to southern and eastern African populations, which involved admixture between indigenous San, Niger-Congo-speaking and populations of Eurasian ancestry. This finding illustrates the need to account for stratification in genome-wide association studies, and that admixture mapping would likely be a successful approach in these populations. We developed a strategy to detect the signature of selection prior to and following putative admixture events. Several genomic regions show an unusual excess of Niger-Kordofanian, and unusual deficiency of both San and Eurasian ancestry, which were considered the footprints of selection after population admixture. Several SNPs with strong allele frequency differences were observed predominantly between the admixed indigenous southern African populations, and their ancestral Eurasian populations. Interestingly, many candidate genes, which were identified within the genomic regions showing signals for selection, were associated with southern African-specific high-risk, mostly communicable diseases, such as malaria, influenza, tuberculosis, and human immunodeficiency virus/AIDs. This observation suggests a potentially important role that these genes might have played in adapting to the environment. Additionally, our analyses of haplotype structure, linkage disequilibrium, recombination, copy number variation and genome-wide admixture highlight, and support the unique position of San relative to both African and non-African populations. This study contributes to a better understanding of population ancestry and selection in south-eastern African populations; and the data and results obtained will support research into the genetic contributions to infectious as well as non-communicable diseases in the region.

    Full Text Available Gene therapy "the use of genes as medicine" involves the transfer of a therapeutic or working copy of a gene into specific cells of an individual in order to repair a faulty gene copy. The technique may be used to replace a faulty gene, or to introduce a new gene whose function is to cure or to favorably modify the clinical course of a condition. The objective of gene therapy is to introduce new genetic material into target cells while causing no damage to the surrounding healthy cells and tissues, hence the treatment related morbidity is decreased. The delivery system includes a vector that delivers a therapeutic gene into the patient′s target cell. Functional proteins are created from the therapeutic gene causing the cell to return to a normal stage. The vectors used in gene therapy can be viral and non-viral. Gene therapy, an emerging field of biomedicine, is still at infancy and much research remains to be done before this approach to the treatment of condition will realize its full potential.

  19. Gisèle d’Estoc: Portraits of a decadent woman

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available A quarrel in the pages of the literary review Le Décadent in 1888 recalls the often belligerent existence of Gisèle d'Estoc, a shadowy figure who stalks the margins of the decadent period and whose life beyond the pages of specialized reviews has long presented something of a mystery. Who was she, and what did she look like? The first question proves the easiest to answer. Tied intimately - by love, by hatred, or by both - to numerous figures of the French decadent movement (Léo Pillard d'Arkaï, Laurent Tailhade, Rachilde, d'Estoc's real name was Marie-Paul Alice Courbe Desbarres. In addition to being the lover of Guy de Maupassant, and of being accused of planting a bomb at the Foyot Restaurant, d'Estoc had an independent career as an artist before launching her literary career in the 1880s. It proves more difficult to know what she looked like, even though she was often represented in paintings, drawings, and photographs. This article analyses some of these representations in order to understand why it is sometimes so difficult to see the decadent woman even when she emerges from the shadows of literary history.

  20. A PORTRAIT OF CHINESE ENTERPRISE THROUGH THE LENS OF ORGANIZATIONAL CULTURE

    Directory of Open Access Journals (Sweden)

    Siew-Huat Kong

    2003-01-01

    Full Text Available By adopting a cultural perspective of organizations, and more specifically, using the structural model of culture as a framework, this investigation attempts to discover the underlying structure of reality in mainland Chinese organizations.This study proposes that at the heart of Chinese organizational culture lie three dominant assumptions, namely "the ever hostile environment", "social reality in hierarchical order", and the "self-seeking human being", which relate to the environment, group, and individual respectively. This triad of assumptions not only animates Chinese organizational culture but also constitutes a unifying thread connecting the different components of this culture. The outward manifestations of this mix of organizational assumptions can best be depicted as a clash of two cultural elitist forces – power and role culture. While power culture is characterized by bonds of personal patronage, personal connections, and displays of personal authority and subservience, role culture emphasizes institutional authority, the rule of law, and meritocracy. The former is presently in command of organizational leadership while the latter has emerged principally as a response to the excesses of the former. Interestingly, although the two cultures are supported by two different sets of values, they rest on a common set of organizational assumptions.

    Mammography is a widely used screening tool for the early detection of breast cancer. One of the commonly missed signs of breast cancer is architectural distortion. The purpose of this study is to explore the application of fractal analysis and texture measures for the detection of architectural distortion in screening mammograms taken prior to the detection of breast cancer. A method based on Gabor filters and phase portrait analysis was used to detect initial candidates for sites of architectural distortion. A total of 386 regions of interest (ROIs) were automatically obtained from 14 ''prior mammograms'', including 21 ROIs related to architectural distortion. From the corresponding set of 14 ''detection mammograms'', 398 ROIs were obtained, including 18 related to breast cancer. For each ROI, the fractal dimension and Haralick's texture features were computed. The fractal dimension of the ROIs was calculated using the circular average power spectrum technique. The average fractal dimension of the normal (false-positive) ROIs was significantly higher than that of the ROIs with architectural distortion (p = 0.006). For the ''prior mammograms'', the best receiver operating characteristics (ROC) performance achieved, in terms of the area under the ROC curve, was 0.80 with a Bayesian classifier using four features including fractal dimension, entropy, sum entropy, and inverse difference moment. Analysis of the performance of the methods with free-response receiver operating characteristics indicated a sensitivity of 0.79 at 8.4 false positives per image in the detection of sites of architectural distortion in the ''prior mammograms''. Fractal dimension offers a promising way to detect the presence of architectural distortion in prior mammograms. (orig.)

    Serial killers are important in American horror because of their ability to exist between ‘myth’ and ‘reality’. The serial killer is one of the most important American myths, but it is one firmly rooted in real life: unlike Paul Bunyan or Superman, serial killers do exist. This essay examines the relationship between the ‘myth’ and the ‘reality’ of serial killers, and the complex relationship between the American public and the serial killer, using Henry: Portrait of a Serial K...

    The 17 Y chromosomal short tandem repeat loci included in the AmpFlSTR® Yfiler™ PCR Amplification Kit were used to analyse the genetic diversity of 517 unrelated males representing the non-tribal and Irula tribal population of Tamil Nadu. A total of 392 unique haplotypes were identified among the 400 non-tribal samples whereas 111 were observed among the 117 Irula tribal samples. Rare alleles for the loci DYS458, DYS635 and YGATAH4.1 were also observed in both population. The haplotype diversity for the non-tribal and Irula tribal population were found to be 0.9999, and the gene diversity ranged from 0.2041 (DYS391) to 0.9612 (DYS385). Comparison of the test population with 26 national and global population using principal coordinate analysis (PCoA) and determination of the genetic distance matrix using phylogenetic molecular analysis indicate a clustering of the Tamil Nadu non-tribal and Irula tribal population away from other unrelated population and proximity towards some Indo-European (IE) and Asian population. Data are available in the Y chromosome haplotype reference database (YHRD) under accession number YA004055 for Tamil non-tribal and YA004056 for the Irula tribal group.

    Fasciola gigantica (Digenea) is an important foodborne trematode that causes liver fluke disease (fascioliasis) in mammals, including ungulates and humans, mainly in tropical climatic zones of the world. Despite its socioeconomic impact, almost nothing is known about the molecular biology of this parasite, its interplay with its hosts, and the pathogenesis of fascioliasis. Modern genomic technologies now provide unique opportunities to rapidly tackle these exciting areas. The present study reports the first transcriptome representing the adult stage of F. gigantica (of bovid origin), defined using a massively parallel sequencing-coupled bioinformatic approach. From >20 million raw sequence reads, >30,000 contiguous sequences were assembled, of which most were novel. Relative levels of transcription were determined for individual molecules, which were also characterized (at the inferred amino acid level) based on homology, gene ontology, and/or pathway mapping. Comparisons of the transcriptome of F. gigantica with those of other trematodes, including F. hepatica, revealed similarities in transcription for molecules inferred to have key roles in parasite-host interactions. Overall, the present dataset should provide a solid foundation for future fundamental genomic, proteomic, and metabolomic explorations of F. gigantica, as well as a basis for applied outcomes such as the development of novel methods of intervention against this neglected parasite.

    Antibacterial resistance is a worldwide threat, and concerns have arisen about the involvement of animal commensal and pathogenic bacteria in the maintenance and spread of resistance genes. However, beyond the facts related to the occurrence of resistant microorganisms in food, food-producing animals and companion animals and their transmission to humans, it is important to consider the vast environmental 'resistome', the selective pathways underlying the emergence of antibacterial resistance and how we can prepare answers for tomorrow.

  10. Spontaneous imbibition in fractal tortuous micro-nano pores considering dynamic contact angle and slip effect: phase portrait analysis and analytical solutions.

    Shales have abundant micro-nano pores. Meanwhile, a considerable amount of fracturing liquid is imbibed spontaneously in the hydraulic fracturing process. The spontaneous imbibition in tortuous micro-nano pores is special to shale, and dynamic contact angle and slippage are two important characteristics. In this work, we mainly investigate spontaneous imbibition considering dynamic contact angle and slip effect in fractal tortuous capillaries. We introduce phase portrait analysis to analyse the dynamic state and stability of imbibition. Moreover, analytical solutions to the imbibition equation are derived under special situations, and the solutions are verified by published data. Finally, we discuss the influences of slip length, dynamic contact angle and gravity on spontaneous imbibition. The analysis shows that phase portrait is an ideal tool for analysing spontaneous imbibition because it can evaluate the process without solving the complex governing ordinary differential equations. Moreover, dynamic contact angle and slip effect play an important role in fluid imbibition in fractal tortuous capillaries. Neglecting slip effect in micro-nano pores apparently underestimates imbibition capability, and ignoring variations in contact angle causes inaccuracy in predicting imbibition speed at the initial stage of the process. Finally, gravity is one of the factors that control the stabilisation of the imbibition process.

    A portrait of Henry VIII on oak panel c. 1535 has recently undergone technical examination to inform questions regarding authorship and the painting's relationship to a group of similar works in the collections of the National Portrait Gallery, London, and the Society of Antiquaries. Due to previous conservation treatments of the painting, the conventional transmission X-radiograph image was difficult to interpret. As a result, the painting underwent high-definition X-ray fluorescence (XRF) elemental mapping on the X-ray fluorescence microscopy beamline of the Australian Synchrotron. Scans were conducted at 12.6 and 18.5 keV, below and above the lead (Pb) L edges, respectively. Typical scan parameters were 120 μm pixel size at 7 ms dwell time, with the largest scan covering an area 545 x 287 mm{sup 2} collected in 23 h (10.8 MP). XRF mapping of the panel has guided the conservation treatment of the painting and the revelation of previously obscured features. It has also provided insight into the process of making of the painting. The informative and detailed elemental maps, alongside ultra-high-definition scans of the painting undertaken before and after varnish and over-paint removal, have assisted in comparison of the finely painted details with the London paintings. The resolution offered by the combination of imaging techniques identifies pigment distribution at an extremely fine scale, enabling a new understanding of the artist's paint application. (orig.)

  12. "Peintre de Sa Majesté Britannique". Franz Adolph of Freenthal and his portrait of Maximilian Hamilton, Prince-Bishop of Olomouc

    Directory of Open Access Journals (Sweden)

    Suchánek, Pavel

    2012-09-01

    Full Text Available This essay examines the portrait of Maximilian von Hamilton (1714-1776, the last Prince-Bishop of Olomouc/Olmütz, painted between 1769 and 1772 by Franz Adolph of Freenthal (1721-1773, a former painter to the British royal court. The study focuses in turn on three visual motifs in Hamilton's portrait: the rhetorical gestures of the sitter, his attire and the way he is depicted, and the form of presentation and the function of the painting in the ceremonial space of the princely residence. In examining each of these motifs, account is taken of the specific visual conventions applied in this genre, and of the contemporary rules of visual rhetoric. By referencing the classical motif of modesty and moderation from antiquity, Adolph underlined the importance of the ideal of antiquity and with it "natural" speech and behaviour. He attempted to express the spirit of antiquity by comparing contemporary clothing and rhetorical gestures to those of the orators or other public figures of antiquity. In a similar way to contemporary British painters, he thus referenced models taken from antiquity, with the aim of evoking a noble past and representing the ideal of the virtue of antiquity.

    Two decades after the initial gene therapy trials and more than 1700 approved clinical trials worldwide we not only have gained much new information and knowledge regarding gene therapy in general, but also learned to understand the concern that has persisted in society. Despite the setbacks gene therapy has faced, success stories have increasingly emerged. Examples for these are the positive recommendation for a gene therapy product (Glybera) by the EMA for approval in the European Union and the positive trials for the treatment of ADA deficiency, SCID-X1 and adrenoleukodystrophy. Nevertheless, our knowledge continues to grow and during the course of time more safety data has become available that helps us to develop better gene therapy approaches. Also, with the increased understanding of molecular medicine, we have been able to develop more specific and efficient gene transfer vectors which are now producing clinical results. In this review, we will take a historical view and highlight some of the milestones that had an important impact on the development of gene therapy. We will also discuss briefly the safety and ethical aspects of gene therapy and address some concerns that have been connected with gene therapy as an important therapeutic modality.

  6. Just what is it that makes identification-portrait hypotheses so appealing? On why Hans Süss von Kulmbach “must” have portrayed John Boner

    Directory of Open Access Journals (Sweden)

    Masza Sitek

    2017-12-01

    Full Text Available The alleged apprentice of Albrecht Dürer, Hans Süss von Kulmbach (d. 1522, ‘must’ have painted at least one crypto-portrait of the Krakow banker John Boner (d. 1523, who went down in history as ‘the Polish Jacob Fugger.’ Such a conviction has seemingly inspired art-history scholarship devoted to Kulmbach and his relations to Poland. What varies is the selection of figures in his religious pictures claimed to represent Boner. This paper aims to examine two best argued theories, which concern two panel paintings preserved in the collection of St Mary’s Basilica in Krakow: Disputation of St Catherine of Alexandria with heathen philosophers, 1514-15, and Self-burial of St John the Evangelist, 1516. The suspect images will be analysed in terms of the enduring ‘premodern’ concept of recognizability, with focus on such aspects as mimesis versus schematism, heraldry and costume.

    A Künstlerroman is a literary genre that focuses on the psychological and moral growth of the protagonist from youth to adulthood, and in which character change is thus extremely important. A portrait of the artist as a young man as a Künstlerro-man also shows the growth process of the protagonist from childhood to youth. The paper aims to point out the growth process of the protagonist focusing on the text. Especially, from the two aspects:content and form. The content and the form together re-flect the growth process of the protagonist and the development of his personality, so we also see the protagonist was destined to be mature and at last decided to escape his home, exile himself and began his new life with the purpose of art.

    Full Text Available his paper will attempt to analyze the clothing from the rococo period and underline fashion as an important segment in the reconstruction of a specific style era. Based on conserved portraits from the second half of the 18th century, as well as rare artifacts of clothing from the period found in Croatia, a description of primarily women’s types of clothing, accessories and the terms used to describe them will be given. Influences had, primarily through cultural and trade routes, come from the fashion capital of the period – France, and fashion innovations and the intensity of their changes were under the influence of the personal style first of Madame de Pompadour and afterwards Marie Antoinette. Croatia, which had at the time been part of the Habsburg monarchy and under the Republic of Venice, tended toward French influences in fashion, which represents a considerable move from the prior influence of Italian and German style.

    How can science inform art and art inform science and how does that interrelationship affect social change, research and the dissemination of scientific evidence? Carol Devine's Aquamess: Portraits of Garbage at the Top of the World project is based on a 2015 civilian expedition, CleanUp Svalbard. Volunteers on this stewardship initiative collected garbage accumulating on the Norwegian archipelago's remote shores as a recognized marine debris mitigation strategy. For four days, Devine and fellow volunteers travelled 10 nautical miles and collected 13.5 metres of garbage including 3.5 cubic metres of plastic fishing nets. Devine documented the effort and created Aquamess, a photography exhibit with garbage 'portraits', noting their geolocations. Her objective was to disseminate knowledge about the global marine debris problem, such as how ocean currents carry plastics, how the density varies due to hydrological and meterological conditions, what gyres are etc., and to encourage dialogue and continued interdisciplinary research and action. At the request of Dr. David Pantalony, Curator at the Canada Science and Technology Museum, Devine also collected a sample of the debris from Svalbard. This "Arctic garbage" is now archival material and part of an upcoming multimedia Oceans exhibit the museum created with her about marine science and ocean health. Already, Aquamess has engaged discussions about marine pollution's impact on human and planetary health in the 2016-7 group show Science Inspires Art: Food at the New York Hall of Science exploring contemporary food issues including food waste. It will be in a November 2017 group exhibit Photography as Response at the Center for Fine Art Photography in Colorado and is the subject of Devine's TEDxMontreal Women talk. Devine has written blogs and articles about Aquamess;has been interviewed in science, sciart and culture journals in the US, Europe, and Canada; and is observing scientific and non-scientific reactions through

    Genes are perpetually added to and deleted from genomes during evolution. Thus, it is important to understand how new genes are formed and evolve as critical components of the genetic systems determining the biological diversity of life. Two decades of effort have shed light on the process of new gene origination, and have contributed to an emerging comprehensive picture of how new genes are added to genomes, ranging from the mechanisms that generate new gene structures to the presence of new genes in different organisms to the rates and patterns of new gene origination and the roles of new genes in phenotypic evolution. We review each of these aspects of new gene evolution, summarizing the main evidence for the origination and importance of new genes in evolution. We highlight findings showing that new genes rapidly change existing genetic systems that govern various molecular, cellular and phenotypic functions. PMID:24050177

    2013-11-01

    Using the Durham Child Health and Development Study, this study (N = 171) tested whether observed parenting behaviors in infancy (6 and 12 months) and toddlerhood/preschool (24 and 36 months) interacted with a child polymorphism of the brain-derived neurotrophic factor gene to predict oppositional defiant disorder (ODD) and callous-unemotional (CU) behaviors at age 3 years. Child genotype interacted with observed harsh and intrusive (but not sensitive) parenting to predict ODD and CU behaviors. Harsh-intrusive parenting was more strongly associated with ODD and CU for children with a methionine allele of the brain-derived neurotrophic factor gene. CU behaviors were uniquely predicted by harsh-intrusive parenting in infancy, whereas ODD behaviors were predicted by harsh-intrusive parenting in both infancy and toddlerhood/preschool. The results are discussed from the perspective of the contributions of caregiving behaviors as contributing to distinct aspects of early onset disruptive behavior.

  17. Medical Emergencies in Goa

    Saddichha, Sahoo; Saxena, Mukul Kumar

    2010-01-01

    Background: Most emergencies in Goa arise due to road traffic accidents and drowning, which have been compounded by the rise in number of recorded accidents in 2007 to be above 4000. It is believed that 11 people meet with an accident on Goa's roads every day and this is expected to rise by 10% by next year. Similar is the case with drownings and other medical emergencies. We therefore aimed to conduct a cross-sectional survey of medical emergencies and identify various types of emergencies presenting to emergency departments. Materials and Methods: Using a stratified random sampling design, all emergencies presenting to the three government hospitals in Goa, which handle 90% of all emergencies currently, were studied on specially designed data sheets in order to collect data. Emergency medical technicians (ETs) were placed in the Casualty Ward of the medical colleges and they recorded all emergencies on the data sheet. The collected data were then analyzed for stratification and mapping of emergencies. Results: GMC Hospital attended to majority of emergencies (62%), which were mainly of the nature of accidents or assaults (17%) and fever related (17%). Most emergencies were noncritical and about 1% expired. Maximum emergencies also presented from Salcette and Bardez, and occurred among young males in the age group of 19-45 years. Males were also more prone to accidents while females had pregnancies as emergencies. Conclusion: Potential emergency services need to target young males with higher concentrations required in Salcette in South Goa and Bardez in North Goa. PMID:20606921

    2015-05-06

    In this review, we discuss new emerging medical applications of the rapidly evolving field of mammalian synthetic biology. We start with simple mammalian synthetic biological components and move towards more complex and therapy-oriented gene circuits. A comprehensive list of ON-OFF switches, categorized into transcriptional, post-transcriptional, translational and post-translational, is presented in the first sections. Subsequently, Boolean logic gates, synthetic mammalian oscillators and toggle switches will be described. Several synthetic gene networks are further reviewed in the medical applications section, including cancer therapy gene circuits, immuno-regulatory networks, among others. The final sections focus on the applicability of synthetic gene networks to drug discovery, drug delivery, receptor-activating gene circuits and mammalian biomanufacturing processes. © 2015 The Author(s) Published by the Royal Society.

    The organization for dealing with radiation emergencies in France is complex and centralized. It consists of the Radiation Security Council with participants from the Premier Ministre and the Ministers of Interior, Industry, Health, and Defense. A permanent general secretary for radiation security coordinates the work of the various departments. Planning for nuclear power emergencies is divided between on-site, in which organization and intervention are the responsibilities of the manager of the plant, and off-site, in which organization and intervention are the responsibility of the regional governor. Both on-site and off-site planning have models integrated into a special code of practice called the radiation emergency organization

    With the rising influence of the Gene On-tology, new approaches have emerged where the similarity between genes or gene products is obtained by comparing Gene Ontology code annotations associ-ated with them. So far, these approaches have solely relied on the knowledge en-coded in the Gene Ontology and the gene annotations associated with the Gene On-tology database. The goal of this paper is to demonstrate that improvements to these approaches can be obtained by integrating textual evidence extracted from relevant biomedical literature.

    2008-11-01

    In recent years, emerging diseases were defined as being infectious, acquiring high incidence, often suddenly, or being a threat or an unexpected phenomenon. This study discusses the hallmarks of emerging diseases, describing the existence of noninfectious emerging diseases, and elaborating on the advantages of defining noninfectious diseases as emerging ones. From the discussion of various mental health disorders, nutritional deficiencies, external injuries and violence outcomes, work injuries and occupational health, and diseases due to environmental factors, the conclusion is drawn that a wide variety of noninfectious diseases can be defined as emergent. Noninfectious emerging diseases need to be identified in order to improve their control and management. A new definition of "emergent disease" is proposed, one that emphasizes the pathways of emergence and conceptual traits, rather than descriptive features.

  13. On meme--gene coevolution.

    Science.gov (United States)

    Bull, L; Holland, O; Blackmore, S

    2000-01-01

    In this article we examine the effects of the emergence of a new replicator, memes, on the evolution of a pre-existing replicator, genes. Using a version of the NKCS model we examine the effects of increasing the rate of meme evolution in relation to the rate of gene evolution, for various degrees of interdependence between the two replicators. That is, the effects of memes' (suggested) more rapid rate of evolution in comparison to that of genes is investigated using a tunable model of coevolution. It is found that, for almost any degree of interdependence between the two replicators, as the rate of meme evolution increases, a phase transition-like dynamic occurs under which memes have a significantly detrimental effect on the evolution of genes, quickly resulting in the cessation of effective gene evolution. Conversely, the memes experience a sharp increase in benefit from increasing their rate of evolution. We then examine the effects of enabling genes to reduce the percentage of gene-detrimental evolutionary steps taken by memes. Here a critical region emerges as the comparative rate of meme evolution increases, such that if genes cannot effectively select memes a high percentage of the time, they suffer from meme evolution as if they had almost no selective capability.

    Williams, Vernon B

    2014-12-01

    Sports neurology is an emerging area of subspecialty. Neurologists and non-neurologists evaluating and managing individuals participating in sports will encounter emergencies that directly or indirectly involve the nervous system. Since the primary specialty of sports medicine physicians and other practitioners involved in the delivery of medical care to athletes in emergency situations varies significantly, experience in recognition and management of neurologic emergencies in sports will vary as well. This article provides a review of information and elements essential to neurologic emergencies in sports for the practicing neurologist, although content may be of benefit to readers of varying background and expertise. Both common neurologic emergencies and less common but noteworthy neurologic emergencies are reviewed in this article. Issues that are fairly unique to sports participation are highlighted in this review. General concepts and principles related to treatment of neurologic emergencies that are often encountered unrelated to sports (eg, recognition and treatment of status epilepticus, increased intracranial pressure) are discussed but are not the focus of this article. Neurologic emergencies can involve any region of the nervous system (eg, brain, spine/spinal cord, peripheral nerves, muscles). In addition to neurologic emergencies that represent direct sports-related neurologic complications, indirect (systemic and generalized) sports-related emergencies with significant neurologic consequences can occur and are also discussed in this article. Neurologists and others involved in the care of athletes should consider neurologic emergencies in sports when planning and providing medical care.

    We prepared probes for isolating functional pieces of the metallothionein locus. The probes enabled a variety of experiments, eventually revealing two mechanisms for metallothionein gene expression, the order of the DNA coding units at the locus, and the location of the gene site in its chromosome. Once the switch regulating metallothionein synthesis was located, it could be joined by recombinant DNA methods to other, unrelated genes, then reintroduced into cells by gene-transfer techniques. The expression of these recombinant genes could then be induced by exposing the cells to Zn 2+ or Cd 2+ . We would thus take advantage of the clearly defined switching properties of the metallothionein gene to manipulate the expression of other, perhaps normally constitutive, genes. Already, despite an incomplete understanding of how the regulatory switch of the metallothionein locus operates, such experiments have been performed successfully

    There are so many emergency issues in our daily life. Such as typhoons, tsunamis, earthquake, fires, floods, epidemics, etc. These emergencies made people lose their lives and their belongings. Every day, every hour, even every minute people probably face the emergency, so how to handle it and how to decrease its hurt are the matters people care most. If we can map it exactly before or after the emergencies; it will be helpful to the emergency researchers and people who live in the emergency place. So , through the emergency map, before emergency is occurring we can predict the situation, such as when and where the emergency will be happen; where people can refuge, etc. After disaster, we can also easily assess the lost, discuss the cause and make the lost less. The primary effect of mapping is offering information to the people who care about the emergency and the researcher who want to study it. Mapping allows the viewers to get a spatial sense of hazard. It can also provide the clues to study the relationship of the phenomenon in emergency. Color, as the basic element of the map, it can simplify and clarify the phenomenon. Color can also affects the general perceptibility of the map, and elicits subjective reactions to the map. It is to say, structure, readability, and the reader's psychological reactions can be affected by the use of color.

  1. Update on emergency contraception.

    Fok, Wing Kay; Blumenthal, Paul D

    2016-12-01

    Emergency contraception provides a critical and time-sensitive opportunity for women to prevent undesired pregnancy after intercourse. Both access and available options for emergency contraception have changed over the last several years. Emergency contraceptive pills can be less effective in obese women. The maximum achieved serum concentration of levonorgestrel (LNG) is lower in obese women than women of normal BMI, and doubling the dose of LNG (3 mg) increases its concentration maximum, approximating the level in normal BMI women receiving one dose of LNG. Repeated use of both LNG and ulipristal acetate (UPA) is well tolerated. Hormonal contraception can be immediately started following LNG use, but should be delayed for 5 days after UPA use to avoid dampening the efficacy of UPA. The copper intrauterine device (IUD) is the only IUD approved for emergency contraception (and the most effective method of emergency contraception), but use of LNG IUD as emergency contraception is currently being investigated. Accurate knowledge about emergency contraception remains low both for patients and healthcare providers. Emergency contraception is an important yet underutilized tool available to women to prevent pregnancy. Current options including copper IUD and emergency contraceptive pills are safe and well tolerated. Significant gaps in knowledge of emergency contraception on both the provider and user level exist, as do barriers to expedient access of emergency contraception.

    to assess the profile and the characteristic of oncological patients, establishing management in patients with neoplasia presented in the emergency department (ED), the analysis of short-term movements in patients with neoplasia whilst in the ED. we performed a retrospective study on nonrandomized consecutive cases. The lot analysis included 1315 oncological patients admitted in the Emergency Department of the Clinical Emergency Hospital "St. Spiridon" Iaşi, in the period June 1st, 2009 - May 31st, 2010. 23.12% of the patients had high suspicion of neoplasia at the first visit to the ED. 67.07% of patients were in metastatic stage disease located as follows: liver metastasis 37.59%, lung metastasis 18.36%, lymph node metastasis 13, 29%. After processing the data there were found statistically significant correlations between the age of patients and the documented/suspected diagnosis of neoplasia (p = 0.01) in the sense that a neoplasia diagnosis in emergency was more frequent in people of young age. It should be mentioned that other studies rarely mention first diagnosis of neoplasia in emergency department with presence of complications. 1315 oncological patients presented in ED, almost a quarter of which presented high suspicion of neoplasia (still without histopathological confirmation) when in ED (23.12%). Most of them were aged male patients (over 65 years old), with tumors of the digestive system. A significant proportion (almost 60%) of these patients ended up in emergency due to complications and the therapy intended life support and pain management. Some of these patients were directed to further exploring and emergency outpatient therapy while 75% of patients were hospitalized after stabilization. Although we expected that the frequency of complications to be higher in patients previously diagnosed with cancer, data analysis showed no statistically significant differences (p = NS) between the rate of complications in patients previously diagnosed with

    Full Text Available The rise of the Evo-Devo field and the development of multidisciplinary research tools at various levels of biological organization have led to a growing interest in researching for new non-model organisms. Squamates (lizards and snakes are particularly important for understanding fundamental questions about the evolution of vertebrates because of their high diversity and evolutionary innovations and adaptations that portrait a striking body plan change that reached its extreme in snakes. Yet, little is known about the intricate connection between phenotype and genotype in squamates, partly due to limited developmental knowledge and incomplete characterization of embryonic development. Surprisingly, squamate models have received limited attention in comparative developmental studies, and only a few species examined so far can be considered as representative and appropriate model organism for mechanistic Evo-Devo studies. Fortunately, the agamid lizard Pogona vitticeps (central bearded dragon is one of the most popular, domesticated reptile species with both a well-established history in captivity and key advantages for research, thus forming an ideal laboratory model system and justifying his recent use in reptile biology research. We first report here the complete post-oviposition embryonic development for P. vitticeps based on standardized staging systems and external morphological characters previously defined for squamates. Whereas the overall morphological development follows the general trends observed in other squamates, our comparisons indicate major differences in the developmental sequence of several tissues, including early craniofacial characters. Detailed analysis of both embryonic skull development and adult skull shape, using a comparative approach integrating CT-scans and gene expression studies in P. vitticeps as well as comparative embryology and 3D geometric morphometrics in a large dataset of lizards and snakes, highlights

  5. Defining an emerging disease.

    Moutou, F; Pastoret, P-P

    2015-04-01

    Defining an emerging disease is not straightforward, as there are several different types of disease emergence. For example, there can be a 'real' emergence of a brand new disease, such as the emergence of bovine spongiform encephalopathy in the 1980s, or a geographic emergence in an area not previously affected, such as the emergence of bluetongue in northern Europe in 2006. In addition, disease can emerge in species formerly not considered affected, e.g. the emergence of bovine tuberculosis in wildlife species since 2000 in France. There can also be an unexpected increase of disease incidence in a known area and a known species, or there may simply be an increase in our knowledge or awareness of a particular disease. What all these emerging diseases have in common is that human activity frequently has a role to play in their emergence. For example, bovine spongiform encephalopathy very probably emerged as a result of changes in the manufacturing of meat-and-bone meal, bluetongue was able to spread to cooler climes as a result of uncontrolled trade in animals, and a relaxation of screening and surveillance for bovine tuberculosis enabled the disease to re-emerge in areas that had been able to drastically reduce the number of cases. Globalisation and population growth will continue to affect the epidemiology of diseases in years to come and ecosystems will continue to evolve. Furthermore, new technologies such as metagenomics and high-throughput sequencing are identifying new microorganisms all the time. Change is the one constant, and diseases will continue to emerge, and we must consider the causes and different types of emergence as we deal with these diseases in the future.

  7. “Too Long in Foreign Parts”?: An Asian Reception to Cosmopolitanism in Henry James’s The American and The Portrait of a Lady

    2012-04-01

    Full Text Available The works of Henry James with their attention to cosmopolitanism in the late nineteenth and early twentieth centuries provide valuable insight into contemporary expectations of cultural hybridity and globalism. This paper assesses the ways students studying English as a foreign language in Taiwan read the cultural exchanges between Americans and Europeans in James’s "The American" (1877 and "The Portrait of a Lady" (1881. It places the main attention upon how students evaluate James’s characters based upon their own attitudes toward cosmopolitanism, work and leisure, and women’s independence. Informed by the travel theory of Mary Louise Pratt (2008 and Homi Bhabha’s (1994 concept of the third space, it studies the negotiation and subversion of meaning in postcolonial and reverse-colonial contexts. The analysis of student responses reveals that in this culturally hybrid reading site, the limited consciousness technique of James generates judgments of characters’ potentialities based upon the students’ own values. Reconciling the cultural oppositions in the self to become a citizen of the world remains an ideal they do not see fully realized in James’s highly conflicted characters, and, as their own partial views attest, not realizable in their own lives.

    In 17th century Old Master Paintings, the underpainting generally refers to the first sketch of a composition. The underpainting is applied to a prepared ground using a monochrome, brown oil paint to roughly indicate light, shade and contours. So far, methods to visualize the underpainting - other than in localized cross-sections - have been very limited. Neither infrared reflectography nor neutron induced autoradiography have proven to be practical, adequate visualization tools. Thus, although of fundamental interest in the understanding of a painting's genesis, the underpainting has virtually escaped all imaging efforts. In this contribution we will show that 17th century underpainting may consist of a highly heterogeneous mixture of pigments, including copper pigments. We suggest that this brown pigment mixture is actually the recycled left-over of a palette scraping. With copper as the heaviest exclusive elemental component, we will hence show in a case study on a Portrait of an Old Man attributed to Rembrandt van Rijn how scanning macro-XRF can be used to efficiently visualize the underpainting below the surface painting and how this information can contribute to the discussion of the painting's authenticity.

    Peripheral artery disease (PAD) is associated with poor health status (symptoms, functioning, quality of life (QOL)). Whether sex differences exist in PAD-specific health status is unknown. In patients presenting to a specialty clinic with new-onset or recent exacerbation of PAD, we examined sex differences as assessed by the Peripheral Artery Questionnaire (PAQ). The Patient-centered Outcomes Related to TReatment Practices in Peripheral Arterial Disease: Investigating Trajectories (PORTRAIT) study is a multicenter, international prospective study of patients with new or worsening PAD symptoms. Baseline characteristics and mean PAQ scores were compared among women ( n=481) and men ( n=793) before they underwent treatment. The independent association of sex with health status was assessed with multivariable linear regression. As compared with men, women were less often Caucasian, married and employed, and more often lacking health insurance, living alone (36.2% vs 23.6%, pPAQ scores on all domains (physical functioning adjusted mean difference of -8.40, p<0.001; social functioning adjusted mean difference of -6.8, p<0.001; QOL adjusted mean difference of -6.7, p<0.001), although no differences were observed in treatment satisfaction (adjusted mean difference -0.20, p=0.904). Despite similar ABIs, women presenting with symptoms of PAD had poorer PAD-specific functioning as compared with men, impacting all major health status domains, independent of socio-economic and clinical characteristics.

  12. Feminism and Postmodernism in Paloma Díaz-Mas's "The World According to Valdés" and "In Search of a Portrait"

    2002-06-01

    Full Text Available This paper analyzes the influence of postmodernism in Paloma Díaz-Mas's feminist approach through two short stories, "The World According to Valdés," and "In Search of a Portrait." The political situation after Franco's death embraced democracy which allowed writers to pay more attention to intellectual concerns. Women writers steered the radical positions of the 1970s toward a more philosophical and intellectual analysis of reality and artistic expression during the eighties. In these two short stories, Díaz-Mas addresses women's issues by questioning the scope of modernist and humanist views. She criticizes the modernist concept of unity (text/identity pointing out the discrimination that this unity creates in art, through the distinction between high art/mass culture; and in the individual, through the distinction between feminine/masculine and high/low. Even though Díaz-Mas's main characters in the two stories are women, she does not solely focus on defending them, but she contrasts present and past to parody the causes which produce discrimination in the social and artistic processes.

    2010-01-01

    Full Text Available This paper aims at presenting and examining Joyce's first novel entitled A Portrait of the Artist as a Young Man which introduces us to the life and artistry of Joyce himself. In addition to this, the special emphasis will be placed on the intellectual growth of the fictional counterpart of Joyce himself, Stephen Dedalus who, for the sake of embracing his true vocation as an artist guided by the unflinch­ing devotion to both truth and beauty, exiles himself from the stifling conventionality of his homeland - Ireland. Envisioning the culture of Ireland as imbued with a series of 'nets' embodied in nationality, church, and family which restrain the initial stimulus of his soul, Joyce's alter ego refuses to bow down before the authority of any institution other than the authority of his art. Much of this paper has been inspired by the work of humanist philosopher Erich Fromm, whose ideas have prompted me to view Joyce in the light of the great Humanist tradition focusing on man's innate capability of creating valid ethical criteria he/she is to live by.

    Professional boxing has done an admirable job in promoting safety standards in its particular sport. However, injuries occur during the normal course of competition and, unfortunately, an occasional life-threatening emergency may arise. Although most common medical emergencies in boxing are injuries from closed head trauma, in this article those infrequent but potentially catastrophic nonneurologic conditions are reviewed along with some less serious emergencies that the physician must be prepared to address.

  16. Transcriptional portrait of Actinobacillus pleuropneumoniae during acute disease--potential strategies for survival and persistence in the host.

    Directory of Open Access Journals (Sweden)

    Kirstine Klitgaard

    Full Text Available BACKGROUND: Gene expression profiles of bacteria in their natural hosts can provide novel insight into the host-pathogen interactions and molecular determinants of bacterial infections. In the present study, the transcriptional profile of the porcine lung pathogen Actinobacillus pleuropneumoniae was monitored during the acute phase of infection in its natural host. METHODOLOGY/PRINCIPAL FINDINGS: Bacterial expression profiles of A. pleuropneumoniae isolated from lung lesions of 25 infected pigs were compared in samples taken 6, 12, 24 and 48 hours post experimental challenge. Within 6 hours, focal, fibrino hemorrhagic lesions could be observed in the pig lungs, indicating that A. pleuropneumoniae had managed to establish itself successfully in the host. We identified 237 differentially regulated genes likely to encode functions required by the bacteria for colonization and survival in the host. This group was dominated by genes involved in various aspects of energy metabolism, especially anaerobic respiration and carbohydrate metabolism. Remodeling of the bacterial envelope and modifications of posttranslational processing of proteins also appeared to be of importance during early infection. The results suggested that A. pleuropneumoniae is using various strategies to increase its fitness, such as applying Na+ pumps as an alternative way of gaining energy. Furthermore, the transcriptional data provided potential clues as to how A. pleuropneumoniae is able to circumvent host immune factors and survive within the hostile environment of host macrophages. This persistence within macrophages may be related to urease activity, mobilization of various stress responses and active evasion of the host defenses by cell surface sialylation. CONCLUSIONS/SIGNIFICANCE: The data presented here highlight the importance of metabolic adjustments to host conditions as virulence factors of infecting microorganisms and help to provide insight into the mechanisms

    2013-01-01

    The Working Group on Inspection Practices (WGIP) was tasked by the NEA CNRA to examine and evaluate the extent to which emergency arrangements are inspected and to identify areas of importance for the development of good inspection practices. WGIP members shared their approaches to the inspection of emergency arrangements by the use of questionnaires, which were developed from the requirements set out in IAEA Safety Standards. Detailed responses to the questionnaires from WGIP member countries have been compiled and are presented in the appendix to this report. The following commendable practices have been drawn from the completed questionnaires and views provided by WGIP members: - RBs and their Inspectors have sufficient knowledge and information regarding operator's arrangements for the preparedness and response to nuclear emergencies, to enable authoritative advice to be given to the national coordinating authority, where necessary. - Inspectors check that the operator's response to a nuclear emergency is adequately integrated with relevant response organisations. - Inspectors pay attention to consider the integration of the operator's response to safety and security threats. - The efficiency of international relations is checked in depth during some exercises (e.g. early warning, assistance and technical information), especially for near-border facilities that could lead to an emergency response abroad. - RB inspection programmes consider the adequacy of arrangements for emergency preparedness and response to multi-unit accidents. - RBs assess the adequacy of arrangements to respond to accidents in other countries. - The RB's role is adequately documented and communicated to all agencies taking part in the response to a nuclear or radiological emergency. - Inspectors check that threat assessments for NPPs have been undertaken in accordance with national requirements and that up-to-date assessments have been used as the basis for developing emergency plans for

    Sakha--an area connecting South and Northeast Siberia--is significant for understanding the history of peopling of Northeast Eurasia and the Americas. Previous studies have shown a genetic contiguity between Siberia and East Asia and the key role of South Siberia in the colonization of Siberia. We report the results of a high-resolution phylogenetic analysis of 701 mtDNAs and 318 Y chromosomes from five native populations of Sakha (Yakuts, Evenks, Evens, Yukaghirs and Dolgans) and of the analysis of more than 500,000 autosomal SNPs of 758 individuals from 55 populations, including 40 previously unpublished samples from Siberia. Phylogenetically terminal clades of East Asian mtDNA haplogroups C and D and Y-chromosome haplogroups N1c, N1b and C3, constituting the core of the gene pool of the native populations from Sakha, connect Sakha and South Siberia. Analysis of autosomal SNP data confirms the genetic continuity between Sakha and South Siberia. Maternal lineages D5a2a2, C4a1c, C4a2, C5b1b and the Yakut-specific STR sub-clade of Y-chromosome haplogroup N1c can be linked to a migration of Yakut ancestors, while the paternal lineage C3c was most likely carried to Sakha by the expansion of the Tungusic people. MtDNA haplogroups Z1a1b and Z1a3, present in Yukaghirs, Evens and Dolgans, show traces of different and probably more ancient migration(s). Analysis of both haploid loci and autosomal SNP data revealed only minor genetic components shared between Sakha and the extreme Northeast Siberia. Although the major part of West Eurasian maternal and paternal lineages in Sakha could originate from recent admixture with East Europeans, mtDNA haplogroups H8, H20a and HV1a1a, as well as Y-chromosome haplogroup J, more probably reflect an ancient gene flow from West Eurasia through Central Asia and South Siberia. Our high-resolution phylogenetic dissection of mtDNA and Y-chromosome haplogroups as well as analysis of autosomal SNP data suggests that Sakha was colonized by

    Full Text Available As urgências e as emergências hipertensivas são ocorrências clínicas que podem representar mais de 25% dos atendimentos a urgências médicas. O médico deverá estar habilitado a diferenciá-las, pois o prognóstico e o tratamento são distintos. Estima-se que 3% de todas as visitas às salas de emergência decorrem de elevações significativas da pressão arterial. Nos quadros relacionados a estes atendimentos, a emergência hipertensiva é a entidade clínica mais grave que merece cuidados intensivos. É caracterizada por pressão arterial marcadamente elevada e sinais de lesões de órgãos-alvo (encefalopatia, infarto agudo do miocárdio, angina instável, edema agudo de pulmão, eclâmpsia, acidente vascular encefálico. O objetivo deste estudo foi apresentar os principais pontos sobre o seu apropriado diagnóstico e tratamento. Foi realizada busca por artigos originais com os unitermos "crise hipertensiva" e "emergência hipertensiva" nas bases de dados Pubmed e MedLine nos últimos dez anos. As referências disponíveis destes artigos foram verificadas. Os artigos foram identificados e revisados e o presente estudo condensa os principais resultados descritos. Para esta revisão foram considerados ensaios clínicos em língua inglesa, estudos retrospectivos e artigos de revisão. A crise hipertensiva é a entidade clínica com aumento súbito da PA (> 180 x 120 mmHg, acompanhada por sintomas, que podem ser leves (cefaléia, tontura, zumbido ou graves (dispnéia, dor precordial, coma e até morte, com ou sem lesão aguda de órgãos-alvo. Se os sintomas forem leves e sem lesão aguda de órgãos alvos, define-se a urgência hipertensiva. Se o quadro clínico apresentar risco de vida e refletir lesão aguda de órgãos-alvo têm-se, então, a emergência hipertensiva. Muitos pacientes também apresentam uma PA elevada demais, por não usarem suas medicações, tratando-se apenas de hipertensão arterial sistêmica crônica n

    A total of 7194 faecal samples collected over a 1-year period from patients presenting with diarrhoea were screened for Campylobacter spp. using EntericBio(®) , a multiplex-PCR system. Of 349 Campylobacter-positive samples, 23.8% were shown to be Campylobacter ureolyticus, using a combination of 16S rRNA gene analysis and highly specific primers targeting the HSP60 gene of this organism. This is, to the best of our knowledge, the first report of C. ureolyticus in the faeces of patients presenting with gastroenteritis and may suggest a role for this organism as an emerging enteric pathogen.

    Full Text Available The objective has been to create a Protocol of Structured Presurgical Visit applicable to the patients who are undergoing an emergency surgery, to provide the user and his family all the necessary cares on the basis of those nursing diagnosis that prevail in all the cases of surgical emergency interventions. The used method has been an analysis of the emergency surgical interventions more prevalent from February 2007 until October 2008 in our area (a regional hospital, and statistic of those nursing diagnosis that more frequently appeared in these interventions, the previous moment to the intervention and in addition common to all of them. The results were the following ones: the more frequent emergency operations were: Caesarean, ginecological curettage, laparotomy, help in risk childbirth, orthopaedic surgery and appendectomy. The more frequent nursing diagnosis in all the emergency operations at the previous moment of the intervention were: risk of falls, pain, anxiety, deficit of knowledge, risk of infection, movement stress syndrome, risk of hemorrhage, cutaneous integrity deterioration. The conclusion is that users present at the previous moment to an emergency operation several problems, which force to the emergency surgical ward nurse to the introduction of the nursing methodology, in order to identify the problems, to mark results and to indicate the interventions to achieve those results, besides in a humanitarian way and with quality. This can be obtained by performing a Structured Emergency Presurgical Visit.

To review the literature and identify key components needed to prevent shootings at higher education institutions in the United States, and in particular, institutions housing radiologic science programs. Twenty-eight emergency preparedness plans were retrieved electronically and reviewed from a convenience sample of accredited radiologic science programs provided by the Joint Review Committee on Education in Radiologic Technology Web site. The review of the 28 emergency preparedness plans confirmed that most colleges are prepared for basic emergencies, but lack the key components needed to successfully address mass-casualty events. Only 5 (18%) of the 28 institutions addressed policies concerning school shootings.

  14. Repeated adaptive introgression at a gene under multiallelic balancing selection.

    Directory of Open Access Journals (Sweden)

    Vincent Castric

    2008-08-01

    Full Text Available Recently diverged species typically have incomplete reproductive barriers, allowing introgression of genetic material from one species into the genomic background of the other. The role of natural selection in preventing or promoting introgression remains contentious. Because of genomic co-adaptation, some chromosomal fragments are expected to be selected against in the new background and resist introgression. In contrast, natural selection should favor introgression for alleles at genes evolving under multi-allelic balancing selection, such as the MHC in vertebrates, disease resistance, or self-incompatibility genes in plants. Here, we test the prediction that negative, frequency-dependent selection on alleles at the multi-allelic gene controlling pistil self-incompatibility specificity in two closely related species, Arabidopsis halleri and A. lyrata, caused introgression at this locus at a higher rate than the genomic background. Polymorphism at this gene is largely shared, and we have identified 18 pairs of S-alleles that are only slightly divergent between the two species. For these pairs of S-alleles, divergence at four-fold degenerate sites (K = 0.0193 is about four times lower than the genomic background (K = 0.0743. We demonstrate that this difference cannot be explained by differences in effective population size between the two types of loci. Rather, our data are most consistent with a five-fold increase of introgression rates for S-alleles as compared to the genomic background, making this study the first documented example of adaptive introgression facilitated by balancing selection. We suggest that this process plays an important role in the maintenance of high allelic diversity and divergence at the S-locus in flowering plant families. Because genes under balancing selection are expected to be among the last to stop introgressing, their comparison in closely related species provides a lower-bound estimate of the time since the

    Hepatic resection is the most curative treatment option for early-stage hepatocellular carcinoma, but is associated with a high recurrence rate, which exceeds 50% at 5 years after surgery. Understanding the genetic basis of hepatocellular carcinoma at surgically curable stages may enable the identification of new molecular biomarkers that accurately identify patients in need of additional early therapeutic interventions. Whole exome sequencing and copy number analysis was performed on 231 hepatocellular carcinomas (72% with hepatitis B viral infection) that were classified as early-stage hepatocellular carcinomas, candidates for surgical resection. Recurrent mutations were validated by Sanger sequencing. Unsupervised genomic analyses identified an association between specific genetic aberrations and postoperative clinical outcomes. Recurrent somatic mutations were identified in nine genes, including TP53, CTNNB1, AXIN1, RPS6KA3, and RB1. Recurrent homozygous deletions in FAM123A, RB1, and CDKN2A, and high-copy amplifications in MYC, RSPO2, CCND1, and FGF19 were detected. Pathway analyses of these genes revealed aberrations in the p53, Wnt, PIK3/Ras, cell cycle, and chromatin remodeling pathways. RB1 mutations were significantly associated with cancer-specific and recurrence-free survival after resection (multivariate P = 0.038 and P = 0.012, respectively). FGF19 amplifications, known to activate Wnt signaling, were mutually exclusive with CTNNB1 and AXIN1 mutations, and significantly associated with cirrhosis (P = 0.017). RB1 mutations can be used as a prognostic molecular biomarker for resectable hepatocellular carcinoma. Further study is required to investigate the potential role of FGF19 amplification in driving hepatocarcinogenesis in patients with liver cirrhosis and to investigate the potential of anti-FGF19 treatment in these patients. © 2014 by the American Association for the Study of Liver Diseases.

  17. Emergence in Dynamical Systems

    2013-12-01

    Full Text Available Emergence is a term used in many contexts in current science; it has become fashionable. It has a traditional usage in philosophy that started in 1875 and was expanded by J. S. Mill (earlier, under a different term and C. D. Broad. It is this form of emergence that I am concerned with here. I distinguish it from uses like ‘computational emergence,’ which can be reduced to combinations of program steps, or its application to merely surprising new features that appear in complex combinations of parts. I will be concerned specifically with ontological emergence that has the logical properties required by Mill and Broad (though there might be some quibbling about the details of their views. I restrict myself to dynamical systems that are embodied in processes. Everything that we can interact with through sensation or action is either dynamical or can be understood in dynamical terms, so this covers all comprehensible forms of emergence in the strong (nonreducible sense I use. I will give general dynamical conditions that underlie the logical conditions traditionally assigned to emergence in nature.The advantage of this is that, though we cannot test logical conditions directly, we can test dynamical conditions. This gives us an empirical and realistic form of emergence, contrary those who say it is a matter of perspective.

  18. Gene doping: possibilities and practicalities.

    2009-01-01

    Our ever-increasing understanding of the genetic control of cardiovascular and musculoskeletal function together with recent technical improvements in genetic manipulation generates mounting concern over the possibility of such technology being abused by athletes in their quest for improved performance. Genetic manipulation in the context of athletic performance is commonly referred to as gene doping. A review of the literature was performed to identify the genes and methodologies most likely to be used for gene doping and the technologies that might be used to identify such doping. A large number of candidate performance-enhancing genes have been identified from animal studies, many of them using transgenic mice. Only a limited number have been shown to be effective following gene transfer into adults. Those that seem most likely to be abused are genes that exert their effects locally and leave little, if any, trace in blood or urine. There is currently no evidence that gene doping has yet been undertaken in competitive athletes but the anti-doping authorities will need to remain vigilant in reviewing this rapidly emerging technology. The detection of gene doping involves some different challenges from other agents and a number of promising approaches are currently being explored. 2009 S. Karger AG, Basel

    There are specific boundary conditions where preparedness for in-plant emergency management is as necessary and useful as is the training for the management of design-based accidents. The shift personnel has to be trained to cope particularly with the difficult and demanding initial phase of an emergency, and care must be taken to be very close to reality. Only thus can weak points be discovered and removed by pinpointed measures such as organisational changes, optimization of emergency management procedures, or hardware conditions. (orig.) [de

    Full Text Available A look at the family portrait in Francoist Spain provides valuable information concerning the Spanish upbringing style and its relationship with the state ideology. A regime of Estado Nuevo (1939–1975 evolved from German and Italian fascism models to national-catholic autoritharianism, and marked all spheres of political, economic and social life. The dominant patriarchal family model, a woman’s role limited to household duties and her spouse’s will, or aggressively promoted by the authorities role models defined for many decades not only the Spanish upbringing style, but also the shape of relationships between family members. The values and norms passed to the youngest had to match the governmental reality, and due to this control, at the stage of primary socialization young people became recipients of propaganda content. From that moment it was constantly presentat every stage of education and professional life of the Spanish nation. As it was in other totalitarian countries, in Spain film was used as a propaganda tool. With the growing interest and availability of this entertainment form, cinema has become a perfect and effective communication and agitation medium. A domestic production was subjected to full control because of the compatibility of the presented content with current ideology, and censorship took care to save the Spanish audience from Western patterns of “depravity and extravagance”. With this background, analysis of the motive of family in selected Spanish films from the Francoist period allows observation of a political involvement of the family and educational processes and phenomena.

    We analysed 15 autosomal STRs in 200 unrelated individuals (102 males and 98 females) and 17 Y-STRs in 102 unrelated males living in Jharkhand, India, to establish parameters of forensic interest. The examined autosomal STRs revealed high combined power of exclusion (CPE) and combined power of discrimination (CPD) as equal to 0.9999 and greater than 0.99999, respectively. The combined probability of match (CP m ) and combined paternity index (CPI) for all 15 autosomal STR loci were found to be 5.15 × 10 -18 and 6.83 × 10 5 , respectively. A total of 97 unique haplotypes were obtained, of which 93 were observed only once. The haplotype diversity, discrimination capacity and matching probability for 17 Y-STR loci were 0.999, 0.951 and 1.09 × 10 -2 , respectively. The highest gene diversity values at the single copy locus DYS635 and multi-copy locus DYS385 a/b were 0.785 and 0.823, respectively.

In the scope of this paper, emergencies are those accidents that may lead to severe releases of oil and gas, whereby also attention is paid to collisions between offshore installations and drifting objects and the situation where people fall overboard. Case histories show that coping with these serious accidents is not always as effective and successful as intended. The stage from being aware of the risks, to being prepared to cope with the consequences, to actually being capable to combat is long and consists of many elements. This paper will deal with the general approach of emergency management, the development of automated tools for decision support on emergencies as well as some fate and effect models

    Acute abdominal pain related to the female genital organs is frequently encountered in the emergency department. Gynecological emergencies are diseases of the female reproductive system that are potentially life-threatening and peril the sexual function and fertility. In the diagnostic work-up of acute abdominal pain, a wide variety of differential diagnoses needs to be considered depending on the age of the patient and a concomitant pregnancy. There is significant clinical overlap with gastrointestinal emergencies. Therefore, imaging plays a key role in diagnosing the cause of the pain and the planning of the therapy. The aim of this review is to illustrate the significant role of imaging in frequently encountered gynecologic emergencies.

  15. Emerging nuclear suppliers

    International Nuclear Information System (INIS)

    Sands, A.

    1990-01-01

    Efforts to prevent the spread of nuclear weapons have usually taken two tracks: The traditional approach has concentrated on a potential proliferant's perceived need for nuclear technology and possibly weapons; a second approach has targeted the supply side of the proliferation equation. The issue being examined in this book---emerging nuclear suppliers---falls between these two approaches. The potential proliferants have emerged as possible unrestrained suppliers of nuclear materials and technology. They threaten the entire nonproliferation regime by their exporting, not their weapons development. Analyzing and understanding the issue of emerging suppliers requires a refined definition of suppliers in general. The simple dichotomy of traditional versus emerging suppliers is no longer an adequate framework for analysis. Suppliers differ significantly in their technical capabilities, experience, and regime involvement, and these distinctions result in different nuclear export policies

    There is an increasing potential for severe accidents as the industrial development tends towards large, centralised production units. In several industries this has led to the formation of large organisations which are prepared for accidents fighting and for emergency management. The functioning of these organisations critically depends upon efficient decision making and exchange of information. This project is aimed at securing and possibly improving the functionality and efficiency of the accident and emergency management by verifying, demonstrating, and validating the possible use of advanced information technology in the organisations mentioned above. With the nuclear industry in focus the project consists of five main activities: 1) The study and detailed analysis of accident and emergency scenarios based on records from incidents and rills in nuclear installations. 2) Development of a conceptual understanding of accident and emergency management with emphasis on distributed decision making, information flow, and control structure sthat are involved. 3) Development of a general experimental methodology for evaluating the effects of different kinds of decision aids and forms of organisation for emergency management systems with distributed decision making. 4) Development and test of a prototype system for a limited part of an accident and emergency organisation to demonstrate the potential use of computer and communication systems, data-base and knowledge base technology, and applications of expert systems and methods used in artificial intelligence. 5) Production of guidelines for the introduction of advanced information technology in the organisations based on evaluation and validation of the prototype system.

    2014-08-01

    Zoonotic diseases are infectious diseases that are naturally transmitted from vertebrate animals to humans and vice versa. They are caused by all types of pathogenic agents, including bacteria, parasites, fungi, viruses and prions. Although they have been recognised for many centuries, their impact on public health has increased in the last few decades due to a combination of the success in reducing the spread of human infectious diseases through vaccination and effective therapies and the emergence of novel zoonotic diseases. It is being increasingly recognised that a One Health approach at the human-animal-ecosystem interface is needed for effective investigation, prevention and control of any emerging zoonotic disease. Here, the authors will review the drivers for emergence, highlight some of the high-impact emerging zoonotic diseases of the last two decades and provide examples of novel One Health approaches for disease investigation, prevention and control. Although this review focuses on emerging zoonotic viral diseases, the authors consider that the discussions presented in this paper will be equally applicable to emerging zoonotic diseases of other pathogen types.

    An emergency nuclear reactor cooling device comprises a water reservoir, emergency core cooling water pipelines having one end connected to a water feeding sparger, fire extinguishing facility pipelines, cooling water pressurizing pumps, a diesel driving machine for driving the pumps and a battery. In a water reservoir, cooling water is stored by an amount required for cooling the reactor upon emergency and for fire extinguishing, and fire extinguishing facility pipelines connecting the water reservoir and the fire extinguishing facility are in communication with the emergency core cooling water pipelines connected to the water feeding sparger by system connection pipelines. Pumps are operated by a diesel power generator to introduce cooling water from the reservoir to the emergency core cooling water pipelines. Then, even in a case where AC electric power source is entirely lost and the emergency core cooling system can not be used, the diesel driving machine is operated using an exclusive battery, thereby enabling to inject cooling water from the water reservoir to a reactor pressure vessel and a reactor container by the diesel drive pump.

    2011-01-01

    The most recent developments in the area of deep DNA sequencing and downstream quantitative and functional analysis are rapidly adding a new dimension to understanding biochemical pathways and metabolic interdependencies. These increasing insights pave the way to designing new strategies that address public needs, including environmental applications and therapeutic inventions, or novel cell factories for sustainable and reconcilable energy or chemicals sources. Adding yet another level is building upon nonnaturally occurring networks and pathways. Recent developments in synthetic biology have created economic and reliable options for designing and synthesizing genes, operons, and eventually complete genomes. Meanwhile, high-throughput design and synthesis of extremely comprehensive DNA sequences have evolved into an enabling technology already indispensable in various life science sectors today. Here, we describe the industrial perspective of modern gene synthesis and its relationship with synthetic biology. Gene synthesis contributed significantly to the emergence of synthetic biology by not only providing the genetic material in high quality and quantity but also enabling its assembly, according to engineering design principles, in a standardized format. Synthetic biology on the other hand, added the need for assembling complex circuits and large complexes, thus fostering the development of appropriate methods and expanding the scope of applications. Synthetic biology has also stimulated interdisciplinary collaboration as well as integration of the broader public by addressing socioeconomic, philosophical, ethical, political, and legal opportunities and concerns. The demand-driven technological achievements of gene synthesis and the implemented processes are exemplified by an industrial setting of large-scale gene synthesis, describing production from order to delivery.

    2006-04-01

    Together with the rapidly increasing knowledge on genetic therapies as a promising new branch of regular medicine, the issue has arisen whether these techniques might be abused in the field of sports. Previous experiences have shown that drugs that are still in the experimental phases of research may find their way into the athletic world. Both the World Anti-Doping Agency (WADA) and the International Olympic Committee (IOC) have expressed concerns about this possibility. As a result, the method of gene doping has been included in the list of prohibited classes of substances and prohibited methods. This review addresses the possible ways in which knowledge gained in the field of genetic therapies may be misused in elite sports. Many genes are readily available which may potentially have an effect on athletic performance. The sporting world will eventually be faced with the phenomena of gene doping to improve athletic performance. A combination of developing detection methods based on gene arrays or proteomics and a clear education program on the associated risks seems to be the most promising preventive method to counteract the possible application of gene doping.

    Dendritic metapopulations have been attributed unique properties by in silico studies, including an elevated genetic diversity relative to a panmictic population of equal total size. These predictions have not been rigorously tested in nature, nor has there been full consideration of the interacting effects among contemporary landscape features, colonization history and life history traits of the target species. We tested for the effects of dendritic structure as well as the relative importance of life history, environmental barriers and historical colonization on the neutral genetic structure of a longnose sucker (Catostomus catostomus) metapopulation in the Kogaluk watershed of northern Labrador, Canada. Samples were collected from eight lakes, genotyped with 17 microsatellites, and aged using opercula. Lakes varied in differentiation, historical and contemporary connectivity, and life history traits. Isolation by distance was detected only by removing two highly genetically differentiated lakes, suggesting a lack of migration-drift equilibrium and the lingering influence of historical factors on genetic structure. Bayesian analyses supported colonization via the Kogaluk's headwaters. The historical concentration of genetic diversity in headwaters inferred by this result was supported by high historical and contemporary effective sizes of the headwater lake, T-Bone. Alternatively, reduced allelic richness in headwaters confirmed the dendritic structure's influence on gene flow, but this did not translate to an elevated metapopulation effective size. A lack of equilibrium and upstream migration may have dampened the effects of dendritic structure. We suggest that interacting historical and contemporary factors prevent the achievement of the idealized traits of a dendritic metapopulation in nature. © 2016 John Wiley & Sons Ltd.

    MicroRNAs (miRNAs) are critical regulators of gene expression, and their role in a wide variety of biological processes, including host antimicrobial defense, is increasingly well described. Consistent with their diverse functional effects, miRNA expression is highly context dependent and shows marked changes upon cellular activation. However, the genetic control of miRNA expression in response to external stimuli and the impact of such perturbations on miRNA-mediated regulatory networks at the population level remain to be determined. Here we assessed changes in miRNA expression upon Mycobacterium tuberculosis infection and mapped expression quantitative trait loci (eQTL) in dendritic cells from a panel of healthy individuals. Genome-wide expression profiling revealed that ∼40% of miRNAs are differentially expressed upon infection. We find that the expression of 3% of miRNAs is controlled by proximate genetic factors, which are enriched in a promoter-specific histone modification associated with active transcription. Notably, we identify two infection-specific response eQTLs, for miR-326 and miR-1260, providing an initial assessment of the impact of genotype-environment interactions on miRNA molecular phenotypes. Furthermore, we show that infection coincides with a marked remodeling of the genome-wide relationships between miRNA and mRNA expression levels. This observation, supplemented by experimental data using the model of miR-29a, sheds light on the role of a set of miRNAs in cellular responses to infection. Collectively, this study increases our understanding of the genetic architecture of miRNA expression in response to infection, and highlights the wide-reaching impact of altering miRNA expression on the transcriptional landscape of a cell.

    2015-04-01

    Although considered an extremely unlikely event, many genes emerge from previously noncoding genomic regions. This review covers the entire life cycle of such de novo genes. Two competing hypotheses about the process of de novo gene birth are discussed as well as the high death rate of de novo genes. Despite the high death rate, some de novo genes are retained and remain functional, even in distantly related species, through their integration into gene networks. Further studies combining gene expression with ribosome profiling in multiple populations across different species will be instrumental for an improved understanding of the evolutionary processes operating on de novo genes.

    Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

  13. Emergency planning zone reduction

    International Nuclear Information System (INIS)

    Edwards, C.

    2002-01-01

    This paper describes the process used by a large industrial Department of Energy (DOE) site to communicate changing hazards to its stakeholders and install the confidence necessary to implement the resulting emergency planning changes. Over the last decade as the sites missions have shifted from full-scale production to a greater emphasis on environmental restoration and waste management, the off-site threat from its operations has substantially decreased. The challenge was to clearly communicate the reduced hazards, install confidence in the technical analysis that documented the hazard reduction, and obtain stakeholder buy-in on the path forward to change the emergency management program. The most significant change to the emergency management program was the proposed reduction of the sites Emergency Planning Zone (EPZ). As the EPZ is defined as an area for which planning is needed to protect the public in the event of an accident, the process became politically challenging. An overview of how the site initially approached this problem and then learned to more substantially involve the state and local emergency preparedness agencies and the local Citizens Advisory Board will be presented.

  15. Hormonal modulation of breast cancer gene expression: implications for intrinsic subtyping in pre-menopausal women

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available Clinics are increasingly adopting gene expression profiling to diagnose breast cancer subtype, providing an intrinsic, molecular portrait of the tumour. For example, the PAM50-based Prosigna test quantifies expression of 50 key genes to classify breast cancer subtype, and this method of classification has been demonstrated to be superior over traditional immunohistochemical methods that detect proteins, to predict risk of disease recurrence. However, these tests were largely developed and validated using breast cancer samples from post-menopausal women. Thus, the accuracy of such tests has not been explored in the context of the hormonal fluctuations in estrogen and progesterone that occur during the menstrual cycle in pre-menopausal women. Concordance between traditional methods of subtyping and the new tests in pre-menopausal women is likely to depend on the stage of the menstrual cycle at which the tissue sample is taken, and the relative effect of hormones on expression of genes versus proteins. The lack of knowledge around the effect of fluctuating estrogen and progesterone on gene expression in breast cancer patients raises serious concerns for intrinsic subtyping in pre-menopausal women, which comprise about 25% of breast cancer diagnoses. Further research on the impact of the menstrual cycle on intrinsic breast cancer profiling is required if pre-menopausal women are to benefit from the new technology of intrinsic subtyping.

  16. Portrait pictures of actors in Ukrainian cinema posters of 1920s - early 1990s (based on the materials of Ukrainian cinema posters collection from the fonds of V. Vernadsky National Library of Ukraine

    2015-01-01

    Full Text Available The author examines cinema posters as a source of visual information. Based on the materials of Ukrainian cinema posters collection of V. Vernadsky National Library of Ukraine, the article analyzes posters, the compositions of which contain portrait pictures of Ukrainian and world cinema actors. It characterizes approaches which were used by the artists during their work of posters creaton in order to present the cinema activity of the actors through the creation of cinema images in graphics or collage technique. The author traces main stylistic peculiarities of the posters with portrait pictures and creative style of certain poster artists. It is worth acknowledging that nowadays unique posters to some films of 1920-1930s which have not been preserved up to the present are of special value as important artistic documents in the history of cinema. Despite the fact that the period of the first third of the twentieth century was an age of silent black-and-white films in the history of cinema, all the posters that accompanied the films release were colored, and together they became a bright and unique page in the history of Ukrainian graphic art and cinema advertising

    2014-05-01

    Full Text Available It is common ground amongst almost all commentators that the world has changed radically over the past 25 years – the 25 years since the fall of the Berlin Wall heralded the ending of the Cold War, the reunification of a tragically divided Europe, and the acceleration of the process of globalisation which has its only comparable period in the decades leading up to the First World War in 1914. When analyzing the Emerging World Order it is important to cover more than Brazil economy or any other individual BRICs or other Emerging Powers. Instead, our analysis will provide a global view about the economic and political global power structures which are evolving and forming before our eyes, and then to talk about the challenges these emerging realities pose for us in Europe, and in the West in general.

    1982-01-01

    Purpose: To smoothen the emergency operation of the control rod in a BWR type reactor and to eliminate the external discharge of radioactively contaminated water. Constitution: A drain receiving tank is connected through a scram valve to the top of a cylinder which is containing a hydraulic piston connected to a trombone-shaped control rod and an accumulator is connected through another scram valve to the bottom of the cylinder. The respective scram valves are constructed to be opened by the reactor emergency shutdown signal from a reactor control system in such a manner that drain valve and a vent valve of the tank normally opened at the standby time are closed after approx. 10 seconds from the opening of the scram valves. In this manner, back pressure is not applied to the hydraulic piston at the emergency time, thereby smoothly operating the control rod. (Sikiya, K.)

    1990-01-01

    Since the early 1980s, a growing amount of attention has been paid to a small group of mostly developing countries that have come to be called the emerging nuclear suppliers. Argentina and Brazil, China and South Korea, India and Pakistan, Spain and Yugoslavia have frequently been mentioned in this category. Their actual and potential nuclear export dealings and policies have been the subject of academic writings and policy papers, of scholarly symposia and exchanges at meetings of the traditional nuclear suppliers. With foundation and other support, UCLA's Center for International and Strategic Affairs has begun a major project to develop a database on the transactions, policies, and export control institutions of the emerging suppliers. This chapter provides some guidelines for policy toward the emerging nuclear suppliers

    In work http://dx.doi.org/10.1103/PhysRevD.86.086001, a surface embedded in flat ℝ{sup 3} is associated to any three hermitian matrices. We study this emergent surface when the matrices are large, by constructing coherent states corresponding to points in the emergent geometry. We find the original matrices determine not only shape of the emergent surface, but also a unique Poisson structure. We prove that commutators of matrix operators correspond to Poisson brackets. Through our construction, we can realize arbitrary noncommutative membranes: for example, we examine a round sphere with a non-spherically symmetric Poisson structure. We also give a natural construction for a noncommutative torus embedded in ℝ{sup 3}. Finally, we make remarks about area and find matrix equations for minimal area surfaces.

  3. PFP Emergency Lighting Study

    International Nuclear Information System (INIS)

    BUSCH, M.S.

    2000-01-01

    NFPA 101, section 5-9 mandates that, where required by building classification, all designated emergency egress routes be provided with adequate emergency lighting in the event of a normal lighting outage. Emergency lighting is to be arranged so that egress routes are illuminated to an average of 1.0 footcandle with a minimum at any point of 0.1 footcandle, as measured at floor level. These levels are permitted to drop to 60% of their original value over the required 90 minute emergency lighting duration after a power outage. The Plutonium Finishing Plant (PFP) has two designations for battery powered egress lights ''Emergency Lights'' are those battery powered lights required by NFPA 101 to provide lighting along officially designated egress routes in those buildings meeting the correct occupancy requirements. Emergency Lights are maintained on a monthly basis by procedure ZSR-12N-001. ''Backup Lights'' are battery powered lights not required by NFPA, but installed in areas where additional light may be needed. The Backup Light locations were identified by PFP Safety and Engineering based on several factors. (1) General occupancy and type of work in the area. Areas occupied briefly during a shiftly surveillance do not require backup lighting while a room occupied fairly frequently or for significant lengths of time will need one or two Backup lights to provide general illumination of the egress points. (2) Complexity of the egress routes. Office spaces with a standard hallway/room configuration will not require Backup Lights while a large room with several subdivisions or irregularly placed rooms, doors, and equipment will require Backup Lights to make egress safer. (3) Reasonable balance between the safety benefits of additional lighting and the man-hours/exposure required for periodic light maintenance. In some plant areas such as building 236-Z, the additional maintenance time and risk of contamination do not warrant having Backup Lights installed in all rooms

    This paper will talk about the technologies that have been emerging over the 25 years since the Human Vision and Electronic Imaging conference began that the conference has been a part of, and that have been a part of the conference, and will look at those technologies that are emerging today, such as social networks, haptic technologies, and still emerging imaging technologies, and what we might look at for the future.Twenty-five years is a long time, and it is not without difficulty that we remember what was emerging in the late 1980s. Yet to be developed: The first commercial digital still camera was not yet on the market, although there were hand held electronic cameras. Personal computers were not displaying standardized images, and image quality was not something that could be talked about in a standardized fashion, if only because image compression algorithms were not standardized yet for several years hence. Even further away were any standards for movie compression standards, there was no personal computer even on the horizon which could display them. What became an emergent technology and filled many sessions later, image comparison and search, was not possible, nor the current emerging technology of social networks- the world wide web was still several years away. Printer technology was still devising dithers and image size manipulations which would consume many years, as would scanning technology, and image quality for both was a major issue for dithers and Fourier noise.From these humble beginnings to the current moves that are changing computing and the meaning of both electronic devices and human interaction with them, we will see a course through the changing technology that holds some features constant for many years, while others come and go.

    In order to cope with accidents beyond the design basis within German nuclear power plants which possibly lead to relevant radiological consequences, the utilities as well as the competent authorities exist emergency organisations. The efficiency, capacity for teamwork and preparedness of such organisations should be tested by regular, efficient exercise activities. Such activities can suitably be based on scenarios which provide challenging tasks for all units of the respective emergency organisation. Thus, the demonstration and further development of the efficiency of the respective organisational structures, including their ability to collaborate, is promoted. (orig.)

    Several severe radiological emergencies were reviewed to determine the likely range of conditions which must be coped with by a mobile teleoperator designed for emergencies. The events reviewed included accidents at TMI (1978), SL-1 (1961), Y-12 (1958), Bethesda (1982), Chalk River (1952 and 1958), Lucens (1969). The important conditions were: radiation fields over 10,000 R/h, severe contamination, possible critical excursion, possible inert atmosphere, temperatures from 50 0 C to -20 0 C, 100% relative humidity, 60-cm-high obstacles, stairs, airlocks, darkness, and lack of electric power

    From February 1986 to March 1988 113 abdominal US exams were performed in emergency situation to evaluate the accuracy of this methodology: 13 were blunt traumas, 18 post-operative complications. A real-time scanner with a linear probe of 5 MHz was employed. The results were confirmed by surgical and/or clinical and instrumental evaluation. In 81% of the examinations, ultrasonography allowed a diagnosis to be made. Gallbladder and biliary pathologies were the most common findings. The results (sensibility 96%, specificity 88%, accuracy 95%) confirm the affidability of ultrasonography in abdominal emergencies, as shown in literature

    This article discusses abdominal aortic emergencies. There is a common thread of risk factors and causes of these diseases, including age, male gender, hypertension, dyslipidemia, and connective tissue disorders. The most common presenting symptom of these disorders is pain, usually in the chest, flank, abdomen, or back. Computed tomography scan is the gold standard for diagnosis of pathologic conditions of the aorta in the hemodynamically stable patient. Treatment consists of a combination of blood pressure and heart rate control and, in many cases, emergent surgical intervention. Copyright © 2017 Elsevier Inc. All rights reserved.

  11. The portrait miniature of Cardinal Zbigniew Oleśnicki on a letter of indulgence issued in 1449 for the Church of All Saints in Cracow

    Directory of Open Access Journals (Sweden)

    Marek Walczak

    2017-12-01

    Full Text Available A particularly interesting example of illuminated document is the indulgence granted to all who would visit the parish church of All Saints in Cracow on the major feasts of the liturgical year, issued by the Cracow Bishop, Cardinal Zbigniew Oleśnicki (1423–1450 in 1449. A piece of parchment is decorated with the miniature composed of two juxtaposed fields, of which the upper one shows Christ with St Peter on His right, surrounded by the community of saints; the bottom field depicts the Pope seated between St Jerome and Cardinal Oleśnicki. This hierarch had been raised to the purple no fewer than three times. For the first time, Pope Eugene IV granted him this dignity with the accompanying title of St Prisca, but Oleśnicki did not accept it. Then Antipope Felix V, elected by the Council of Basle, elevated Oleśnicki to the cardinalate (with the title of St Anastasia, but the Cracow prelate likely did not accept the cardinal’s hat again and did not use the title, abiding by the orders of King Ladislaus the Jagiellon who was reluctant towards the Council. It was only in 1447 that Oleśnicki had relinquished the camp of the Council’s supporters, regarded by Rome as schismatics, and endorsed the rightful pope, Nicholas V. Oleśnicki received the cardinal’s hat sent from Rome in Cracow Cathedral, on 1 October 1449. The portrait composition on the Cracow miniature is complex and combining a few iconographic solutions popular in the late Middle Ages. Of particular significance seem to be the representation of the pope enthroned, the Traditio legis and Traditio clavium, as well as the juxtaposition of ecclesiastical hierarchy with the heavenly one. The Cracow miniature fitted perfectly in the then current problems of Church discussed anew in the mid-fifteenth century. Commissioned shortly after Oleśnicki had pledged obedience to Nicholas V and had received his cardinal’s hat, it is a public declaration by the former conciliarist of his new

    Full Text Available The city of Londrina (north of Paraná State emancipated politically on December 10, 1934, five years after the arrival of the pioneers of the Companhia de Terras Norte do Paraná (CTNP - mostly English owned company that began colonization in 1929. In October 1934, two months before being elevated to the status of municipality, was born the first communication vehicle in the city, the newspaper Paraná-Norte. Present from the beginning, the press reported on its pages the transformations that city suffered through the years, being a document of important historical value. This study therefore aims to analyze the beginning of the trajectory ofLondrina's press from the place occupied by the image in the pages of the city's first newspaper, Paraná-Norte (1934-1953 and the magazine A Pioneira (1948-1954. To understand the importance of photography published in such vehicles as trace for writing the history ofLondrina, it employed some research methodologies. The first was the literature, followed by the documentary analysis (MOREIRA, 2009 for all editions of the newspaper and magazine available to the public consultation, which allowed to write about the history of the two media pioneers. Already a comparative study of photography in Paraná-Norte and A Pioneira was done by iconographic analysis, proposed by Kossoy (2001. Faced with the impossibility of studying the universe of photographs published by two journals, we chose to select, via random draw, one copy per year of circulation newspaper and magazine. Thus, the study focused on 18 editions of Paraná-Norte (for the years 1951 and 1952 there are no copies available and 7 of the magazine A Pioneira. Drawing on theoretical frameworks that deal with interfaces between story and image, press photography and memory, portraits and family albums, we conclude that, although the use of imagery has been explored differently by the two vehicles, even because of difficulties technical and financial, in

    1993-01-01

    The system of the present invention can determine an emergency operation coping with abnormal events occurring during nuclear plant operation without replying on an operator's judgement. That is, the system of the present invention comprises an intelligence base which divides and classifies the aims of the plant operation for the function, structure and operation manual and puts them into network. Degree of attainment for the extend of the status normality is determined on every aim of operation based on various kinds of measured data during plant operation. For a degree of attainment within a predetermined range, it is judged that an emergency operation is possible although this is in an abnormal state. Degree of emergency is determined by a fuzzy theory based on the degree of attainment, variation coefficient for the degree of attainment and the sensitivity to external disturbance as parameters. Priority for the degree of emergency on every operation aims is determined by comparison. Normality is successively checked for the determined operation aims. As a result, equipments as objects of abnormality suppressing operation are specified, and the operation amount of the equipments as objects are determined so that the measuring data are within a predetermined range.

  14. Biodosimetry: emergency preparedness

    International Nuclear Information System (INIS)

    Pradeepkumar, K.S.

    2016-01-01

    Biodosimetry assays are the only methods available for ascertaining and estimating biological dose for suspected over-exposures and manage radiological emergency situations. These methods also plays a major role in medical management and triage. In the eventuality of radiological emergency, it becomes inevitable to provide care for exposed individuals. However, large numbers of unexposed individuals or those with clinically insignificant doses are to be screened off for effective medical management of those who really need the specialized medical attention. Majority of individuals involved in radiological accidents may not need any medical attention but will need ascertainment of dose estimation and counselling. The decision making and counselling is possible only with the evidence of dose estimation. Though Biodosimetry procedures-are known for their inherent delay, since radiation effects are very slow in nature, give ample time for such investigations to be completed without any hurry to take medical actions in most cases. High throughput facilities in the state of the art Biodosimetry lab established at HS and EG, BARC has helped us to address many small scale radiological emergencies in the past. These experiences also helped the lab to prepare itself for large scale scenario and support the emergency management with continually improving preparedness and indigenous development of facilities.

    2015-04-01

    During and after disasters, focus is directed toward meeting the immediate needs of the general population. As a result, the routine health care and the special needs of some vulnerable populations such as pregnant and postpartum women may be overlooked within a resource-limited setting. In the event of hazards such as natural disasters, manmade disasters, and terrorism, knowledge of emergency preparedness strategies is imperative for the pregnant woman and her family, obstetric providers, and hospitals. Individualized plans for the pregnant woman and her family should include knowledge of shelter in place, birth at home, and evacuation. Obstetric providers need to have a personal disaster plan in place that accounts for work responsibilities in case of an emergency and business continuity strategies to continue to provide care to their communities. Hospitals should have a comprehensive emergency preparedness program utilizing an "all hazards" approach to meet the needs of pregnant and postpartum women and other vulnerable populations during disasters. With lessons learned in recent tragedies such as Hurricane Katrina in mind, we hope this review will stimulate emergency preparedness discussions and actions among obstetric providers and attenuate adverse outcomes related to catastrophes in the future.

    Gaston K. Mazandu

    2012-01-01

    Full Text Available The wide coverage and biological relevance of the Gene Ontology (GO, confirmed through its successful use in protein function prediction, have led to the growth in its popularity. In order to exploit the extent of biological knowledge that GO offers in describing genes or groups of genes, there is a need for an efficient, scalable similarity measure for GO terms and GO-annotated proteins. While several GO similarity measures exist, none adequately addresses all issues surrounding the design and usage of the ontology. We introduce a new metric for measuring the distance between two GO terms using the intrinsic topology of the GO-DAG, thus enabling the measurement of functional similarities between proteins based on their GO annotations. We assess the performance of this metric using a ROC analysis on human protein-protein interaction datasets and correlation coefficient analysis on the selected set of protein pairs from the CESSM online tool. This metric achieves good performance compared to the existing annotation-based GO measures. We used this new metric to assess functional similarity between orthologues, and show that it is effective at determining whether orthologues are annotated with similar functions and identifying cases where annotation is inconsistent between orthologues.

    Utility emergency preparedness exercises constitute an important link in upgrading the response to nuclear power plant emergencies. Various emergency exercises are arranged annually at the Loviisa nuclear power plant. The on-site simulator is a practical tool in developing suitable accident scenarios and demonstrating them to the site emergency players and spectators. The exercises concentrate on emergency management and radiological activities. It is important to create a high degree of motivation. (author)

    Operation Enduring Freedom (OEF-A) in Afghanistan and Operation Iraqi Freedom (OIF) represent the first major, sustained wars in which emergency physicians (EPs) fully participated as an integrated part of the military's health system. EPs proved invaluable in the deployments, and they frequently used the full spectrum of trauma and medical care skills. The roles EPs served expanded over the years of the conflicts and demonstrated the unique skill set of emergency medicine (EM) training. EPs supported elite special operations units, served in medical command positions, and developed and staffed flying intensive care units. EPs have brought their combat experience home to civilian practice. This narrative review summarizes the history, contributions, and lessons learned by EPs during OEF-A/OIF and describes changes to daily clinical practice of EM derived from the combat environment.

    This is a clinical approach regarding 43 resection of intestine, performed in emergency condition, terminated as enterostomy, with represent 20% of enterectomyes performed in emergency condition and 1.6% of urgent operations. The decision of enterostomy has been taken in the conditions of peritoneal sepsis, occlusion or the association of the two circumstances. The results are comparatively analyzed between the cases with enterostomy that has been made from the beginning (66% success, 33% gone wrong), and those with enterostomy made at the second intervention (14% success, 86% gone wrong). One discusses problems of leading, technique and post-operating nursing. The intestinal reintegration has been made possible at 16 patients after a timing of three of four weeks.

    The Chernobyl disaster prompted authorities in Belgium to carry out a comprehensive review of all emergency plans and, in particular, those designed specifically for nuclear accidents. This review was aimed at determining what type of plans existed and to what extent such plans were operational. This paper sets out to present a broad overview of different aspects of this problem: organization of public emergency plans, co-ordination of operations, merits and demerits of centralization as opposed to decentralization, planning zones, obligation to release information to the public and relations with the media, and finally the international dimension to the problem. The author expresses the hope that the latter area will inspire practical suggestions [fr

    Several emerging or disruptive technologies can be identified that might, at some point in the future, displace established laboratory medicine technologies and practices. These include increased automation in the form of robots, 3-D printing, technology convergence (e.g., plug-in glucose meters for smart phones), new point-of-care technologies (e.g., contact lenses with sensors, digital and wireless enabled pregnancy tests) and testing locations (e.g., Retail Health Clinics, new at-home testing formats), new types of specimens (e.g., cell free DNA), big biology/data (e.g., million genome projects), and new regulations (e.g., for laboratory developed tests). In addition, there are many emerging technologies (e.g., planar arrays, mass spectrometry) that might find even broader application in the future and therefore also disrupt current practice. One interesting source of disruptive technology may prove to be the Qualcomm Tricorder XPrize, currently in its final stages.

    Overuse of hospital emergency rooms (HERs) is parallel to their controversy. To understand this problem, some concepts should be first clarified. In HERs, there are some intrinsic aspects which are directly related to the emergency itself and thus cannot be modified (intermittent patient flow, need to prioritize, difficulty to achieve a rapid diagnosis, influence of time on treatment, value of clinical follow up, patient's expectations, impact of HER on the overall hospital working dynamics). On the other hand, there are some extrinsic aspects which indeed are not related to HER itself but are rather historically associated with it (precarious structure, delay on admission, lack of privacy, inadequate triage of cases, lack of professionalization); these latter aspects may be potentially modified and should be reconsidered.

    The ambulance service is very important in emergency medicine. The aim of this study was to investigate the new governing statuate of private ambulance service and to propose some new ideas. We examinated the new governing statuate of private ambulance service, rules of patient transporte between the hospitals and reports written by SSK Goztepe Educational Hospital ambulance drivers. We concluded that SSK Goztepe Educational Hospital ambulance drivers have a iot of problems especially at the rules of patient transport between the hospitals and there are some defiencies at the new governing statuate of private ambulance service. We concluded that it is necesssary to manage all the ambulance services in one center; all the private ambulance services have to have a specialist and all these must be determinated by the special rules. Key words: Regulation ofprivate ambulance, emergency head maintanence, ambulance services

  17. Hantaviruses as emergent zoonoses

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Hantaviruses belong to the Bunyaviridae family, which consists of vector-borne viruses. These viruses can provoke two infection types: hemorrhagic fever with renal syndrome (HFRS - which occurs in the Old World - and hantavirus cardiopulmonary syndrome (HCPS - an emergent zoonosis that can be found in many countries of the western hemisphere. Rodents are hantavirus reservoirs and each species seems to host a different virus type. Humans acquire the infection by inhaling contaminated aerosol particles eliminated by infected animals. The factors involved in the emergence of hantavirus infections in the human population include ecological modifications and changes in human activities. The most important risk factor is contact between man and rodents, as a result of agricultural, forestry or military activities. Rodent control remains the primary strategy for preventing hantavirus diseases, including via health education and hygienic habits.

    Experiments on the combined action of radiation and a DNA inhibitor using Crepis roots and on split-dose irradiation of human lymphocytes lead to the conclusion that there are two types of repair. The 'regular' repair takes place twice in each mitotic cycle and ensures the maintenance of genetic stability. The 'emergency' repair is induced at all stages of the mitotic cycle by high levels of injury. (author)
