  1. Enhancer SINEs Link Pol III to Pol II Transcription in Neurons

    Full Text Available Summary: Spatiotemporal regulation of gene expression depends on the cooperation of multiple mechanisms, including the functional interaction of promoters with distally located enhancers. Here, we show that, in cortical neurons, a subset of short interspersed nuclear elements (SINEs located in the proximity of activity-regulated genes bears features of enhancers. Enhancer SINEs (eSINEs recruit the Pol III cofactor complex TFIIIC in a stimulus-dependent manner and are transcribed by Pol III in response to neuronal depolarization. Characterization of an eSINE located in proximity to the Fos gene (FosRSINE1 indicated that the FosRSINE1-encoded transcript interacts with Pol II at the Fos promoter and mediates Fos relocation to Pol II factories, providing an unprecedented molecular link between Pol III and Pol II transcription. Strikingly, knockdown of the FosRSINE1 transcript induces defects of both cortical radial migration in vivo and activity-dependent dendritogenesis in vitro, demonstrating that FosRSINE1 acts as a strong enhancer of Fos expression in diverse physiological contexts. : Spatiotemporal regulation of gene expression requires the interaction between promoters and distally located enhancers. Policarpi et al. identify a subset of SINEs that functions as enhancers for activity-dependent neuronal genes. The enhancer SINE FosRSINE1 regulates Fos transcription and is necessary for both activity-dependent dendritogenesis and proper brain development.

    The majority of bacteria possess a different set of specialized DNA polymerases than those identified in the most common model organism Escherichia coli. Here, we have studied the ability of specialized DNA polymerases to substitute Pol I in DNA replication in Pseudomonas putida. Our results revealed that P. putida Pol I-deficient cells have severe growth defects in LB medium, which is accompanied by filamentous cell morphology. However, growth of Pol I-deficient bacteria on solid rich medium can be restored by reduction of reactive oxygen species in cells. Also, mutants with improved growth emerge rapidly. Similarly to the initial Pol I-deficient P. putida, its adapted derivatives express a moderate mutator phenotype, which indicates that DNA replication carried out in the absence of Pol I is erroneous both in the original Pol I-deficient bacteria and the adapted derivatives. Analysis of the spectra of spontaneous Rif r mutations in P. putida strains lacking different DNA polymerases revealed that the presence of specialized DNA polymerases Pol II and Pol IV influences the frequency of certain base substitutions in Pol I-proficient and Pol I-deficient backgrounds in opposite ways. Involvement of another specialized DNA polymerase DnaE2 in DNA replication in Pol I-deficient bacteria is stimulated by UV irradiation of bacteria, implying that DnaE2-provided translesion synthesis partially substitutes the absence of Pol I in cells containing heavily damaged DNA.

  3. Evidence that Mediator is essential for Pol II transcription, but is not a required component of the preinitiation complex in vivo.

    The Mediator complex has been described as a general transcription factor, but it is unclear if it is essential for Pol II transcription and/or is a required component of the preinitiation complex (PIC) in vivo. Here, we show that depletion of individual subunits, even those essential for cell growth, causes a general but only modest decrease in transcription. In contrast, simultaneous depletion of all Mediator modules causes a drastic decrease in transcription. Depletion of head or middle subunits, but not tail subunits, causes a downstream shift in the Pol II occupancy profile, suggesting that Mediator at the core promoter inhibits promoter escape. Interestingly, a functional PIC and Pol II transcription can occur when Mediator is not detected at core promoters. These results provide strong evidence that Mediator is essential for Pol II transcription and stimulates PIC formation, but it is not a required component of the PIC in vivo.

    The molecular basis of human characteristics is an intriguing but an unresolved problem. Human characteristics cover a broad spectrum, from the obvious to the abstract. Obvious characteristics may include morphological features such as height, shape, and facial form. Abstract characteristics may be hidden in processes that are controlled by hormones and the human brain. In this review we examine exaggerated characteristics presented as syndromes. Specifically, we focus on human genes that encode transcription factors to examine morphological, immunological, and hormonal anomalies that result from deletion, insertion, or mutation of genes that regulate transcription by RNA polymerase II (the Pol II genes). A close analysis of abnormal phenotypes can give clues into how sequence variations in regulatory genes and changes in transcriptional control may give rise to characteristics defined as complex traits.

    Although it is established that some general transcription factors are inactivated at mitosis, many details of mitotic transcription inhibition (MTI) and its underlying mechanisms are largely unknown. We have identified mitotic transcriptional activation (MTA) as a key regulatory step to control transcription in mitosis for genes with transcriptionally engaged RNA polymerase II (Pol II) to activate and transcribe until the end of the gene to clear Pol II from mitotic chromatin, followed by global impairment of transcription reinitiation through MTI. Global nascent RNA sequencing and RNA fluorescence in situ hybridization demonstrate the existence of transcriptionally engaged Pol II in early mitosis. Both genetic and chemical inhibition of P-TEFb in mitosis lead to delays in the progression of cell division. Together, our study reveals a mechanism for MTA and MTI whereby transcriptionally engaged Pol II can progress into productive elongation and finish transcription to allow proper cellular division.

    Transcription by RNA polymerase II (Pol II) in eukaryotes requires the Mediator complex, and often involves chromatin remodeling and histone eviction at active promoters. Here we address the role of Mediator in recruitment of the Swi/Snf chromatin remodeling complex and its role, along with components of the preinitiation complex (PIC), in histone eviction at inducible and constitutively active promoters in the budding yeast Saccharomyces cerevisiae. We show that recruitment of the Swi/Snf chromatin remodeling complex to the induced CHA1 promoter, as well as its association with several constitutively active promoters, depends on the Mediator complex but is independent of Mediator at the induced MET2 and MET6 genes. Although transcriptional activation and histone eviction at CHA1 depends on Swi/Snf, Swi/Snf recruitment is not sufficient for histone eviction at the induced CHA1 promoter. Loss of Swi/Snf activity does not affect histone occupancy of several constitutively active promoters; in contrast, higher histone occupancy is seen at these promoters in Mediator and PIC component mutants. We propose that an initial activator-dependent, nucleosome remodeling step allows PIC components to outcompete histones for occupancy of promoter sequences. We also observe reduced promoter association of Mediator and TATA-binding protein in a Pol II (rpb1-1) mutant, indicating mutually cooperative binding of these components of the transcription machinery and indicating that it is the PIC as a whole whose binding results in stable histone eviction.

  13. RNA Pol II promotes transcription of centromeric satellite DNA in beetles.

    Directory of Open Access Journals (Sweden)

    Zeljka Pezer

    Full Text Available Transcripts of centromeric satellite DNAs are known to play a role in heterochromatin formation as well as in establishment of the kinetochore. However, little is known about basic mechanisms of satellite DNA expression within constitutive heterochromatin and its regulation. Here we present comprehensive analysis of transcription of abundant centromeric satellite DNA, PRAT from beetle Palorus ratzeburgii (Coleoptera. This satellite is characterized by preservation and extreme sequence conservation among evolutionarily distant insect species. PRAT is expressed in all three developmental stages: larvae, pupae and adults at similar level. Transcripts are abundant comprising 0.033% of total RNA and are heterogeneous in size ranging from 0.5 kb up to more than 5 kb. Transcription proceeds from both strands but with 10 fold different expression intensity and transcripts are not processed into siRNAs. Most of the transcripts (80% are not polyadenylated and remain in the nucleus while a small portion is exported to the cytoplasm. Multiple, irregularly distributed transcription initiation sites as well as termination sites have been mapped within the PRAT sequence using primer extension and RLM-RACE. The presence of cap structure as well as poly(A tails in a portion of the transcripts indicate RNA polymerase II-dependent transcription and a putative polymerase II promoter site overlaps the most conserved part of the PRAT sequence. The treatment of larvae with alpha-amanitin decreases the level of PRAT transcripts at concentrations that selectively inhibit pol II activity. In conclusion, stable, RNA polymerase II dependant transcripts of abundant centromeric satellite DNA, not regulated by RNAi, have been identified and characterized. This study offers a basic understanding of expression of highly abundant heterochromatic DNA which in beetle species constitutes up to 50% of the genome.

  14. Replication restart in UV-irradiated Escherichia coli involving pols II, III, V, PriA, RecA and RecFOR proteins.

    In Escherichia coli, UV-irradiated cells resume DNA synthesis after a transient inhibition by a process called replication restart. To elucidate the role of several key proteins involved in this process, we have analysed the time dependence of replication restart in strains carrying a combination of mutations in lexA, recA, polB (pol II), umuDC (pol V), priA, dnaC, recF, recO or recR. We find that both pol II and the origin-independent primosome-assembling function of PriA are essential for the immediate recovery of DNA synthesis after UV irradiation. In their absence, translesion replication or 'replication readthrough' occurs approximately 50 min after UV and is pol V-dependent. In a wild-type, lexA+ background, mutations in recF, recO or recR block both pathways. Similar results were obtained with a lexA(Def) recF strain. However, lexA(Def) recO or lexA(Def) recR strains, although unable to facilitate PriA-pol II-dependent restart, were able to perform pol V-dependent readthrough. The defects in restart attributed to mutations in recF, recO or recR were suppressed in a recA730 lexA(Def) strain expressing constitutively activated RecA (RecA*). Our data suggest that in a wild-type background, RecF, O and R are important for the induction of the SOS response and the formation of RecA*-dependent recombination intermediates necessary for PriA/Pol II-dependent replication restart. In con-trast, only RecF is required for the activation of RecA that leads to the formation of pol V (UmuD'2C) and facilitates replication readthrough.

  16. Pol II promoter prediction using characteristic 4-mer motifs: a machine learning approach

    Directory of Open Access Journals (Sweden)

    2008-10-01

    Full Text Available Abstract Background Eukaryotic promoter prediction using computational analysis techniques is one of the most difficult jobs in computational genomics that is essential for constructing and understanding genetic regulatory networks. The increased availability of sequence data for various eukaryotic organisms in recent years has necessitated for better tools and techniques for the prediction and analysis of promoters in eukaryotic sequences. Many promoter prediction methods and tools have been developed to date but they have yet to provide acceptable predictive performance. One obvious criteria to improve on current methods is to devise a better system for selecting appropriate features of promoters that distinguish them from non-promoters. Secondly improved performance can be achieved by enhancing the predictive ability of the machine learning algorithms used. Results In this paper, a novel approach is presented in which 128 4-mer motifs in conjunction with a non-linear machine-learning algorithm utilising a Support Vector Machine (SVM are used to distinguish between promoter and non-promoter DNA sequences. By applying this approach to plant, Drosophila, human, mouse and rat sequences, the classification model has showed 7-fold cross-validation percentage accuracies of 83.81%, 94.82%, 91.25%, 90.77% and 82.35% respectively. The high sensitivity and specificity value of 0.86 and 0.90 for plant; 0.96 and 0.92 for Drosophila; 0.88 and 0.92 for human; 0.78 and 0.84 for mouse and 0.82 and 0.80 for rat demonstrate that this technique is less prone to false positive results and exhibits better performance than many other tools. Moreover, this model successfully identifies location of promoter using TATA weight matrix. Conclusion The high sensitivity and specificity indicate that 4-mer frequencies in conjunction with supervised machine-learning methods can be beneficial in the identification of RNA pol II promoters comparative to other methods.

Se estudian las actitudes colectivas del grupo y la evolución de la cultura política nobiliaria en el contexto de las profundas transformaciones que el ejercicio del poder experimentó en el periodo. Grandes y títulos hubieron de dar respuesta a la sucesión de escenarios políticos y, al mismo tiempo, influyeron decisivamente en la marcha de los asuntos. El progresivo deterioro de la autoridad regia determinó el paso a una poliarquía, a un modelo de múltiples centros de poder de equilibrios precarios que reflejaba el debate sobre el absolutismo y la participación política de la alta nobleza. Factores externos, como la cuestión sucesoria y la injerencia de las potencias extranjeras, y factores internos, como la incapacidad nobiliaria de cohesionarse en un proyecto común, la esperanza en liderazgos imposibles y las limitaciones de su cultura política, produjeron la rápida degeneración de la poliarquía en un régimen caótico en el crepúsculo del siglo XVII.ABSTRACT: This paper is focused on the political behaviour of the Spanish aristocracy under the reign of Charles II. It examines the group's general attitudes and the evolution of the noble political consciousness in a context where the exercise of power underwent deep changes. Grandees and titles had to react towards the series of political scenes and at the same time, they decisively had an influence over the course of events. The progressive impairment of the royal authority gave place to a polyarchy, a model of manifold control centres of precarious balance, which reflected the debate between the absolutism and the upper nobility's political concern. External factors, such as successory matters and foreign countries interference, and internal factors, like the noble inability to integrate themselves into a common project, the expectation around

    In vitro transcription is an essential tool to study the molecular mechanisms of transcription. For over a decade, we have developed an in vitro transcription system from tobacco (Nicotiana tabacum)-cultured cells (BY-2), and this system supported the basic activities of the three RNA polymerases (Pol I, Pol II, and Pol III). However, it was not suitable to study photosynthetic genes, because BY-2 cells have lost their photosynthetic activity. Therefore, Arabidopsis (Arabidopsis thaliana) in vitro transcription systems were developed from green and etiolated suspension cells. Sufficient in vitro Pol II activity was detected after the minor modification of the nuclear soluble extracts preparation method; removal of vacuoles from protoplasts and L-ascorbic acid supplementation in the extraction buffer were particularly effective. Surprisingly, all four Arabidopsis Rubisco small subunit (rbcS-1A, rbcS-1B, rbcS-2B, and rbcS-3B) gene members were in vitro transcribed from the naked DNA templates without any light-dependent manner. However, clear light-inducible transcriptions were observed using chromatin template of rbcS-1A gene, which was prepared with a human nucleosome assembly protein 1 (hNAP1) and HeLa histones. This suggested that a key determinant of light-dependency through the rbcS gene transcription was a higher order of DNA structure (i.e. chromatin). PMID:26662274

    Full Text Available Simulation experiences provide experiential learning opportunities during artificially produced real-life medical situations in a safe environment. Evidence supports using simulation in health care education yet limited quantitative evidence exists in occupational therapy. This study aimed to evaluate the differences in scores on the AOTA Fieldwork Performance Evaluation for the Occupational Therapy Student of Level II occupational therapy students who received high-fidelity simulation training and students who did not. A retrospective analysis of 180 students from a private university was used. Independent samples nonparametric t tests examined mean differences between Fieldwork Performance Evaluation scores of those who did and did not receive simulation experiences in the curriculum. Mean ranks were also analyzed for subsection scores and practice settings. Results of this study found no significant difference in overall Fieldwork Performance Evaluation scores between the two groups. The students who completed simulation and had fieldwork in inpatient rehabilitation had the greatest increase in mean rank scores and increases in several subsections. The outcome measure used in this study was found to have limited discriminatory capability and may have affected the results; however, this study finds that using simulation may be a beneficial supplement to didactic coursework in occupational therapy curriculums.

    National Occupational Dose Registry System (NODRS) of Bhabha Atomic Research Centre maintains and updates occupational dose data of all monitored radiation workers in the country. The registry was upgraded in 2008 by establishing networked NODRS system through which personnel monitoring labs at different nuclear installations were networked with main dose registry server using the departmental ANUNET and NPCNET facilities. This has facilitated online allotment of personal numbers, storing of biometric information as well as providing online dose information to respective Health Physics Units (HPUs). On the basis of operational experience of NODRS and its feedback from users, Phase-II program was designed, developed and implemented. The paper gives an overview of implementation of this program at various sites

    Many apoptotic genes are regulated via alternative splicing (AS) but little is known about the mechanisms controlling AS in stress situations derived from DNA damage. Here we show that ultraviolet (UV) radiation affects co-transcriptional, but not post transcriptional, AS through a systemic mechanism involving a CDK-9-dependent hyper phosphorylation of RNA polymerase II carboxy terminal domain (CTD) and a subsequent and unprecedented inhibition of transcriptional elongation, estimated in vivo and in real time by FRAP. To mimic this hyper phosphorylation we used CTD mutants with serines 2 or 5 substituted by glutamic acids and found that they not only display lower elongation rates but duplicate the effects of UV light on AS in the absence of irradiation. Consistently, substitution of the serines with alanines prevents the UV effect on splicing. These results represent the first in vivo proof of modulation of elongation in response to an environmental signal, affecting in turn the kinetic coupling between transcription and splicing.

Trata-se de pesquisa qualitativa que utilizou grupos focais e entrevistas com os 58 alunos dos cursos. Na dimensão educacional, a qualificação profissional recebida foi insuficiente e não preparou os alunos para enfrentar os desafios do mercado de trabalho. A maioria continua buscando cursos como forma de aumentar as chances de trabalho. Na dimensão econômica, a maior parte dos jovens permaneceu desempregada, e na dimensão psicossocial observou-se referência às questões relativas à subjetividade, à autoestima, melhor comunicação e sociabilidade. Quanto à dimensão político-social, o maior ganho dos alunos foi na compreensão dos seus direitos como cidadãos, mas esta não os levou a atuar nos espaços da sociedade civil, como sindicatos e movimentos sociais. Conclui-se que as percepções dos alunos e os sentidos que atribuem ao Programa refletem as contradições da política, indicando que os jovens não são somente receptores passivos, mas sujeitos de direitos e protagonistas que reivindicam uma formação que atenda aos seus interesses.This article aims to analyze the students' expectations with regard to the vocational training courses provided under the "Projovem Trabalhador" occupational health arch, in Rio de Janeiro, the educational concepts and strategies used in the courses, and the changes that took place in their social situation in the educational, economic, psychosocial and socio-political dimensions.

Building occupants affect building energy use directly and indirectly by interacting with building energy systems such as adjusting temperature set...... occupant profiles for prediction of energy use to reduce the gap between predicted and real building energy consumptions. In this study, we exploit diary-based Danish Time Use Surveys for understanding and modelling occupant behaviour in the residential sector in Denmark. This paper is a continuation......-points, switching lights on/off, using electrical devices and opening/closing windows. Furthermore, building inhabitants’ daily activity profiles clearly shape the timing of energy demand in households. Modelling energy-related human activities throughout the day, therefore, is crucial to defining more realistic...

    Mitomycin C (MMC) is a genotoxic agent that induces DNA cross-links, DNA alkylation, and the production of reactive oxygen species (ROS). MMC induces the SOS response and RpoS regulons in Escherichia coli SOS-encoded functions are required for DNA repair, whereas the RpoS regulon is typically induced by metabolic stresses that slow growth. Thus, induction of the RpoS regulon by MMC may be coincidental, because DNA damage slows growth; alternatively, the RpoS regulon may be an adaptive response contributing to cell survival. In this study, we show that the RpoS regulon is primarily induced by MMC-induced ROS production. We also show that RpoS regulon induction is required for the survival of MMC-treated growing cells. The major contributor to RpoS-dependent resistance to MMC treatment is DNA polymerase Pol II, which is encoded by the polB gene belonging to the SOS regulon. The observation that polB gene expression is controlled by the two major stress response regulons that are required to maximize survival and fitness further emphasizes the key role of this DNA polymerase as an important factor in genome stability.

    Full Text Available Se presenta una tentativa de análisis del comportamiento de los gobernadores provinciales andaluces en su relación con las organizaciones políticas locales entre los años 1931 y 1936. Se establecen vínculos entre tales comportamientos y la sucesión de eventos políticos nacionales y locales. Para ello se emplea la información disponible en la Gaceta de Madrid (el órgano oficial español de la administración pública, así como recortes de la prensa local procedente de las ochos provincias andaluzas. Se analiza la estabilidad de los gobiernos en el ejercicio de sus responsabilidades mediante la comparación del promedio general presentado por cada provincia.

    Full Text Available Foi realizada revisão bibliográfica analítica com o objetivo de quantificar o impacto dos efeitos da ocupação sobre a mortalidade de trabalhadores em suas implicações sobre o setor saúde. As repercussões sobre a mortalidade de trabalhadores são medidas através das mortes diretamente relacionadas com o trabalho (acidentes do trabalho fatais e intoxicações fatais e das indiretamente relacionadas. Partindo das grandes causas de morte entre adultos - doenças cardiovasculares, câncer e mortes violentas - e explorando as informações obtidas em estudos epidemiológicos realizados em outros países, estimou-se a força da contribuição da ocupação sobre a mortalidade. O peso e a complexidade das repercussões sobre o setor saúde pressupõem um desempenho mais ativo na definição de políticas e responsabilidades, e na organização de ações destinadas a identificar, reduzir ou eliminar a participação dos riscos ocupacionais nas grandes causas de doença e morte.An attempt to estimate the impact of occupation on worker's health was made as part of the rationale for the progressive integration of Occupational Health into the Health Sector. In this second study, based on a critical review of the literature, the repercussions on mortality are discussed on this basis analysis of the Brazilian data on deaths directly related to occupation (fatal occupational accidents and acute poisonings, as well as on those indirectly so related. The analysis of the major causes of adult deaths - cardiovascular diseases, cancer and violent deaths - compared with the proportion of "work-relatedness" according to several epidemiologic studies carried out in developed countries, make possible an estimation of the influence of the contribution of occupation on mortality. The size of this contribution is the main argument for an active involvement of the health sector in Occupational Health issues, because of the heavy toll in terms of adult morbidity

  10. Global gene expression analysis of fission yeast mutants impaired in Ser-2 phosphorylation of the RNA pol II carboxy terminal domain.

    Directory of Open Access Journals (Sweden)

    Reza Saberianfar

    Full Text Available In Schizosaccharomyces pombe the nuclear-localized Lsk1p-Lsc1p cyclin dependent kinase complex promotes Ser-2 phosphorylation of the heptad repeats found within the RNA pol II carboxy terminal domain (CTD. Here, we first provide evidence supporting the existence of a third previously uncharacterized Ser-2 CTD kinase subunit, Lsg1p. As expected for a component of the complex, Lsg1p localizes to the nucleus, promotes Ser-2 phosphorylation of the CTD, and physically interacts with both Lsk1p and Lsc1p in vivo. Interestingly, we also demonstrate that lsg1Δ mutants--just like lsk1Δ and lsc1Δ strains--are compromised in their ability to faithfully and reliably complete cytokinesis. Next, to address whether kinase mediated alterations in CTD phosphorylation might selectively alter the expression of genes with roles in cytokinesis and/or the cytoskeleton, global gene expression profiles were analyzed. Mutants impaired in Ser-2 phosphorylation display little change with respect to the level of transcription of most genes. However, genes affecting cytokinesis--including the actin interacting protein gene, aip1--as well as genes with roles in meiosis, are included in a small subset that are differentially regulated. Significantly, genetic analysis of lsk1Δ aip1Δ double mutants is consistent with Lsk1p and Aip1p acting in a linear pathway with respect to the regulation of cytokinesis.

    We describe a ribonucleic acid (RNA) reporter system for live-cell imaging of gene expression to detect changes in polymerase II activity on individual promoters in individual cells. The reporters use strings of RNA aptamers that constitute IMAGEtags (Intracellular MultiAptamer GEnetic tags) that can be expressed from a promoter of choice. For imaging, the cells are incubated with their ligands that are separately conjugated with one of the FRET pair, Cy3 and Cy5. The IMAGEtags were expressed in yeast from the GAL1, ADH1 or ACT1 promoters. Transcription from all three promoters was imaged in live cells and transcriptional increases from the GAL1 promoter were observed with time after adding galactose. Expression of the IMAGEtags did not affect cell proliferation or endogenous gene expression. Advantages of this method are that no foreign proteins are produced in the cells that could be toxic or otherwise influence the cellular response as they accumulate, the IMAGEtags are short lived and oxygen is not required to generate their signals. The IMAGEtag RNA reporter system provides a means of tracking changes in transcriptional activity in live cells and in real time.

    Published ages of >50 ka for occupation at Madjedbebe (Malakunanja II) in Australia's north have kept the site prominent in discussions about the colonisation of Sahul. The site also contains one of the largest stone artefact assemblages in Sahul for this early period. However, the stone artefacts and other important archaeological components of the site have never been described in detail, leading to persistent doubts about its stratigraphic integrity. We report on our analysis of the stone artefacts and faunal and other materials recovered during the 1989 excavations, as well as the stratigraphy and depositional history recorded by the original excavators. We demonstrate that the technology and raw materials of the early assemblage are distinctive from those in the overlying layers. Silcrete and quartzite artefacts are common in the early assemblage, which also includes edge-ground axe fragments and ground haematite. The lower flaked stone assemblage is distinctive, comprising a mix of long convergent flakes, some radial flakes with faceted platforms, and many small thin silcrete flakes that we interpret as thinning flakes. Residue and use-wear analysis indicate occasional grinding of haematite and woodworking, as well as frequent abrading of platform edges on thinning flakes. We conclude that previous claims of extensive displacement of artefacts and post-depositional disturbance may have been overstated. The stone artefacts and stratigraphic details support previous claims for human occupation 50-60 ka and show that human occupation during this time differed from later periods. We discuss the implications of these new data for understanding the first human colonisation of Sahul. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2011-07-01

    Since the Civil War, a proportion of U.S. service members continues to return from war with new health problems and continues to reference battlefield exposures as the cause. Hence, one of the most pressing public health debates in military policy, the determination of causality and linking of battlefield exposures to health outcomes in veterans, continues. The advances in military environmental and occupational epidemiologic research and Department of Defense policy concerning battlefield exposures are summarized and examples from World War II through the first Gulf War are provided. The limitations associated with the unique battlefield environment, multiple environmental exposures, and the inherent stresses of war, beget challenges for researchers responsible for determining causality. In light of these difficulties, six strategies for addressing environmental exposures and their possible impact on veterans were recommended by the Institute of Medicine post Operation Desert Storm. These strategies, along with their respective progress and remaining gaps, are addressed.

  15. Inference of RNA polymerase II transcription dynamics from chromatin immunoprecipitation time course data.

    2014-05-01

    Full Text Available Gene transcription mediated by RNA polymerase II (pol-II is a key step in gene expression. The dynamics of pol-II moving along the transcribed region influence the rate and timing of gene expression. In this work, we present a probabilistic model of transcription dynamics which is fitted to pol-II occupancy time course data measured using ChIP-Seq. The model can be used to estimate transcription speed and to infer the temporal pol-II activity profile at the gene promoter. Model parameters are estimated using either maximum likelihood estimation or via Bayesian inference using Markov chain Monte Carlo sampling. The Bayesian approach provides confidence intervals for parameter estimates and allows the use of priors that capture domain knowledge, e.g. the expected range of transcription speeds, based on previous experiments. The model describes the movement of pol-II down the gene body and can be used to identify the time of induction for transcriptionally engaged genes. By clustering the inferred promoter activity time profiles, we are able to determine which genes respond quickly to stimuli and group genes that share activity profiles and may therefore be co-regulated. We apply our methodology to biological data obtained using ChIP-seq to measure pol-II occupancy genome-wide when MCF-7 human breast cancer cells are treated with estradiol (E2. The transcription speeds we obtain agree with those obtained previously for smaller numbers of genes with the advantage that our approach can be applied genome-wide. We validate the biological significance of the pol-II promoter activity clusters by investigating cluster-specific transcription factor binding patterns and determining canonical pathway enrichment. We find that rapidly induced genes are enriched for both estrogen receptor alpha (ERα and FOXA1 binding in their proximal promoter regions.

  16. ENTROPY PRODUCTION IN COLLISIONLESS SYSTEMS. II. ARBITRARY PHASE-SPACE OCCUPATION NUMBERS

    Barnes, Eric I.; Williams, Liliya L. R.

    2012-01-01

    We present an analysis of two thermodynamic techniques for determining equilibria of self-gravitating systems. One is the Lynden-Bell (LB) entropy maximization analysis that introduced violent relaxation. Since we do not use the Stirling approximation, which is invalid at small occupation numbers, our systems have finite mass, unlike LB's isothermal spheres. (Instead of Stirling, we utilize a very accurate smooth approximation for ln x!.) The second analysis extends entropy production extremization to self-gravitating systems, also without the use of the Stirling approximation. In addition to the LB statistical family characterized by the exclusion principle in phase space, and designed to treat collisionless systems, we also apply the two approaches to the Maxwell-Boltzmann (MB) families, which have no exclusion principle and hence represent collisional systems. We implicitly assume that all of the phase space is equally accessible. We derive entropy production expressions for both families and give the extremum conditions for entropy production. Surprisingly, our analysis indicates that extremizing entropy production rate results in systems that have maximum entropy, in both LB and MB statistics. In other words, both thermodynamic approaches lead to the same equilibrium structures.

    2013-10-20

    BACKGROUND: High-occupancy target (HOT) regions are compact genome loci occupied by many different transcription factors (TFs). HOT regions were initially defined in invertebrate model organisms, and we here show that they are a ubiquitous feature of the human gene-regulation landscape. RESULTS: We identified HOT regions by a comprehensive analysis of ChIP-seq data from 96 DNA-associated proteins in 5 human cell lines. Most HOT regions co-localize with RNA polymerase II binding sites, but many are not near the promoters of annotated genes. At HOT promoters, TF occupancy is strongly predictive of transcription preinitiation complex recruitment and moderately predictive of initiating Pol II recruitment, but only weakly predictive of elongating Pol II and RNA transcript abundance. TF occupancy varies quantitatively within human HOT regions; we used this variation to discover novel associations between TFs. The sequence motif associated with any given TF\\'s direct DNA binding is somewhat predictive of its empirical occupancy, but a great deal of occupancy occurs at sites without the TF\\'s motif, implying indirect recruitment by another TF whose motif is present. CONCLUSIONS: Mammalian HOT regions are regulatory hubs that integrate the signals from diverse regulatory pathways to quantitatively tune the promoter for RNA polymerase II recruitment.

    Influenza virus intimately associates with host RNA polymerase II (Pol II) and mRNA processing machinery. Here, we use mammalian native elongating transcript sequencing (mNET-seq) to examine Pol II behavior during viral infection. We show that influenza virus executes a two-pronged attack on host transcription. First, viral infection causes decreased Pol II gene occupancy downstream of transcription start sites. Second, virus-induced cellular stress leads to a catastrophic failure of Pol II termination at poly(A) sites, with transcription often continuing for tens of kilobases. Defective Pol II termination occurs independently of the ability of the viral NS1 protein to interfere with host mRNA processing. Instead, this termination defect is a common effect of diverse cellular stresses and underlies the production of previously reported downstream-of-gene transcripts (DoGs). Our work has implications for understanding not only host-virus interactions but also fundamental aspects of mammalian transcription. Copyright © 2018 The Author(s). Published by Elsevier Inc.

    Gallo-Fernández, M

    Since 1986, the Government of Navarra has taken over the functions of security and health as part of the health 'area', with a broad conception of health, avoiding separating the citizen from the worker. In 1993, the Instituto Navarro de Salud Laboral created, under the direction of the departments of Health and Labor, combined diverse functions and resources, integrating preexisting structures into a technical department to be responsible for the overall health care of workers. The structure is based on two coordinated pillars, security and hygiene at work and occupational health. As more specifically to do with health, we describe the systems of epidemiological information and vigilance and programs for occupational disabilities, health activities in industry and investigation of diseases. The Unidades de Salud Laboral link the workplace with the public health service. The occupational health plan of Navarra will set out future strategies. It is necessary to involve neurologists in occupational health. Occupational risks and injury are everyone's problem. The neurologist's role in accidents is usually of health care; detection of illness is more difficult when an occupational relationship is not considered. Data from work should be included in the clinical history. The official figures for occupational neurological diseases are ridiculous and more cases should be detected. There should be a fluid relationship between neurologists, occupational doctors and experts in prevention.

  2. Stimulation of Pol III-dependent 5S rRNA and U6 snRNA gene expression by AP-1 transcription factors.

    RNA polymerase III transcribes structurally diverse group of essential noncoding RNAs including 5S ribosomal RNA (5SrRNA) and U6 snRNA. These noncoding RNAs are involved in RNA processing and ribosome biogenesis, thus, coupling Pol III activity to the rate of protein synthesis, cell growth, and proliferation. Even though a few Pol II-associated transcription factors have been reported to participate in Pol III-dependent transcription, its activation by activator protein 1 (AP-1) factors, c-Fos and c-Jun, has remained unexplored. Here, we show that c-Fos and c-Jun bind to specific sites in the regulatory regions of 5S rRNA (type I) and U6 snRNA (type III) gene promoters and stimulate their transcription. Our chromatin immunoprecipitation studies suggested that endogenous AP-1 factors bind to their cognate promoter elements during the G1/S transition of cell cycle apparently synchronous with Pol III transcriptional activity. Furthermore, the interaction of c-Jun with histone acetyltransferase p300 promoted the recruitment of p300/CBP complex on the promoters and facilitated the occupancy of Pol III transcriptional machinery via histone acetylation and chromatin remodeling. The findings of our study, together, suggest that AP-1 factors are novel regulators of Pol III-driven 5S rRNA and U6 snRNA expression with a potential role in cell proliferation. © 2017 Federation of European Biochemical Societies.

    At the end of World War II and during the first decade after the war, roughly 200,000 children were fathered in intimate contacts between German women and foreign soldiers. The experiences of these German occupation children (GOC) have been so far described in case reports and from historical perspective only. Research on psychosocial consequences of growing up as a GOC has been missing so far. This study examined traumatic experiences, posttraumatic stress disorder, somatization, and depression in GOC (N = 146) using self-report instruments: Posttraumatic Diagnostic Scale and Patient Health Questionnaire. Findings have then been compared with a representative birth cohort-matched sample from the German general population (N = 977). German occupation children showed significantly higher prevalence rates of most traumatic experiences, higher point prevalence rates of full and partial posttraumatic stress disorder, depression, and somatization than the control group. In summary, GOC often grew up under difficult conditions (e.g., poverty, single mothers, and stigmatization). Even decades later, they showed higher rates of different mental disorders and higher comorbidity. These findings underline the complex and long-term impact of their burdened social, financial, and familial conditions. The results underpin the importance of conceptualizing occupation children as a vulnerable group in postconflict settings.

    This memorandum transmits recommendations that would update previous guidance to Federal agencies for the protection of workers exposed to ionizing radiation. These recommendations were developed cooperatively by the Nuclear Regulatory Commission, the Occupational Safety and Health Administration, the Mine Safety and Health Administration, the Department of Defense, the Department of Energy, the National Aeronautics and Space Administration, the Department of Commerce, the Department of Transportation, the Department of Health and Human Services, and the Environmental Protection Agency. In addition, the National Council on Radiation Protection and Measurements (NCRP), the National Academy of Sciences (NAS), the Conference of Radiation Control Program Directors (CRCPD) of the States, and the Health Physics Society were consulted during the development of this guidance. These recommendations are based on consideration of (1) current scientific understanding of effects on health from ionizing radiation, (2) recommendations of international and national organizations involved in radiation protection, (3) proposed 'Federal Radiation Protection Guidance for Occupational Exposure' published on January 23, 1981 (46 FR 7836) and public comments on that proposed guidance, and (4) the collective experience of the Federal agencies in the control of occupational exposure to ionizing radiation.

  8. Genome-wide RNA polymerase II profiles and RNA accumulation reveal kinetics of transcription and associated epigenetic changes during diurnal cycles.

    Directory of Open Access Journals (Sweden)

    Gwendal Le Martelot

    Full Text Available Interactions of cell-autonomous circadian oscillators with diurnal cycles govern the temporal compartmentalization of cell physiology in mammals. To understand the transcriptional and epigenetic basis of diurnal rhythms in mouse liver genome-wide, we generated temporal DNA occupancy profiles by RNA polymerase II (Pol II as well as profiles of the histone modifications H3K4me3 and H3K36me3. We used these data to quantify the relationships of phases and amplitudes between different marks. We found that rhythmic Pol II recruitment at promoters rather than rhythmic transition from paused to productive elongation underlies diurnal gene transcription, a conclusion further supported by modeling. Moreover, Pol II occupancy preceded mRNA accumulation by 3 hours, consistent with mRNA half-lives. Both methylation marks showed that the epigenetic landscape is highly dynamic and globally remodeled during the 24-hour cycle. While promoters of transcribed genes had tri-methylated H3K4 even at their trough activity times, tri-methylation levels reached their peak, on average, 1 hour after Pol II. Meanwhile, rhythms in tri-methylation of H3K36 lagged transcription by 3 hours. Finally, modeling profiles of Pol II occupancy and mRNA accumulation identified three classes of genes: one showing rhythmicity both in transcriptional and mRNA accumulation, a second class with rhythmic transcription but flat mRNA levels, and a third with constant transcription but rhythmic mRNAs. The latter class emphasizes widespread temporally gated posttranscriptional regulation in the mouse liver.

    Full Text Available Verifica-se que o turismo tem passado por inúmeras transformações no que concerne ao planejamento e gestão da atividade. Observa-se que desde a década de 1970 tem-se pensado em diferentes modelos de desenvolvimento de turismo para a Amazônia, almejando o progresso econômico e social. Neste processo, na década de 1970, a Superintendência de Desenvolvimento da Amazônia (SUDAM, deu inicio a discursão de criação do primeiro Plano de Turismo da Amazônia (PTA que deu inicio na década de 1980 até 1985. A partir da década de 1990 as estratégias de turismo para a região foram desenvolvidas em conformidade com a preocupação mundial em torno da natureza e do homem. Produto deste contexto, o II PTA foi lançado com o objetivo principal de desenvolver medidas que conciliassem o desenvolvimento econômico às questões ambientais e sociais. Outra ação também importante para esse período foi a promoção do desenvolvimento regional por meio de polos de turismo integrados, conforme determinava o PROECOTUR. O objetivo deste artigo, portanto, consiste em destacar as primeiras políticas públicas de turismo para o desenvolvimento dos estados e municípios da Amazônia que deram inicio a partir de 1970. Para isso, a estruturação conceitual do trabalho fundamentou-se em políticas públicas e planejamento de turismo na Amazônia.

    We report diffusion Monte Carlo (DMC) calculations of the quantum translation-rotation (T-R) dynamics of one to five para-H2 (p-H2) and ortho-D2 (o-D2) molecules inside the large hexakaidecahedral (51264) cage of the structure II clathrate hydrate, which was taken to be rigid. These calculations provide a quantitative description of the size evolution of the ground-state properties, energetics, and the vibrationally averaged geometries, of small (p-H2)n and (o-D2)n clusters, n=1-5, in nanoconfinement. The zero-point energy (ZPE) of the T-R motions rises steeply with the cluster size, reaching 74% of the potential well depth for the caged (p-H2)4. At low temperatures, the rapid increase of the cluster ZPE as a function of n is the main factor that limits the occupancy of the large cage to at most four H2 or D2 molecules, in agreement with experiments. Our DMC results concerning the vibrationally averaged spatial distribution of four D2 molecules, their mean distance from the cage center, the D2-D2 separation, and the specific orientation and localization of the tetrahedral (D2)4 cluster relative to the framework of the large cage, agree very well with the low-temperature neutron diffraction experiments involving the large cage with the quadruple D2 occupancy.

    Full Text Available The article analyses the evolution of Brazilian tariff policy between 1844 and 1889. At first a review of the various tariff schedules adopted during the period is made, with their main features highlighted. The next section seeks to assess the impact of tariff policy on the degree of protection afforded to the domestic sector. To that effect, three types of exercises are carried out: first, the “real cost of imports” and its determinants are calculated; we then calculate coefficients of partial correlation between the quantity of imports, GDP, price of imports, the rate of exchange and import tariffs; finally, we estimate econometrically import demand equations. The exercises reveal that during the II Reign tariffs were important in explaining variations in total imports, although this importance diminished after 1869.

    Methylated histones H3K9 and H3K27 are canonical epigenetic silencing modifications in metazoan organisms, but the relationship between the two modifications has not been well characterized. H3K9me3 coexists with H3K27me3 in pluripotent and differentiated cells. However, we find that the functioning of H3K9me3 is altered by H3S10 phosphorylation in differentiated postmitotic osteoblasts and cycling B cells. Deposition of H3K9me3/S10ph at silent genes is partially mediated by the mitogen- and stress-activated kinases (MSK1/2) and the Aurora B kinase. Acquisition of H3K9me3/S10ph during differentiation correlates with loss of paused S5 phosphorylated RNA polymerase II, which is present on Polycomb-regulated genes in embryonic stem cells. Reduction of the levels of H3K9me3/S10ph by kinase inhibition results in increased binding of RNAPIIS5ph and the H3K27 methyltransferase Ezh1 at silent promoters. Our results provide evidence of a novel developmentally regulated methyl-phospho switch that modulates Polycomb regulation in differentiated cells and stabilizes repressed states.

    2008-06-01

    Full Text Available This article deals with the process of proclamation as Caliph of Cordoba of Hišām, son and next-in-line to al-Ḥakam II, when he was scarcely eleven years old. Two problems are analyzed in relation to this aspect. On the one hand, from a legal point of view, it is brought into question the lawfulness of the government of an under age in the classical Islamic societies. On the other hand, the political crisis produced by the proclamation of Hišām as a consequence of the opposition to his proclamation in certain juridical and palatine circles. In this context, Ibn Abī ‘Āmir, the future Almanzor, managed to usurp the political authority, pushing aside the caliph and making in that way the caliphal institution fall into disrepute. As a result, the proclamation of Hišām constitutes the first stage of the crisis of the Cordoban caliphate, which finally led to its collapse.

    Este artículo aborda el proceso de proclamación como califa de Córdoba de Hišām, hijo y sucesor de al-Ḥakam II, cuando era todavía un niño de apenas once años. En relación con este aspecto, se analizan dos problemas. Desde el punto de vista jurídico, la cuestión de la legalidad del gobierno de un menor de edad en las sociedades islámicas clásicas. Por otro lado, la crisis política que la proclamación de Hišām desencadenó, debido a las resistencias que generaba en ciertos medios palatinos y jurídicos su minoría. En este contexto, Ibn Abī ‘Āmir, futuro Almanzor, logró usurpar el ejercicio del poder, marginando por completo al califa y provocando con ello el descrédito de la institución califal. Por todo ello, la proclamación de Hišām constituye la primera fase en la crisis del califato de Córdoba, que acabó desembocando en su abolición.

  19. Streptococcus suis: a re-emerging pathogen associated with occupational exposure to pigs or pork products. Part II – Pathogenesis

    Full Text Available Streptococcus suis is a re-emerging zoonotic pathogen that may cause severe disease, mostly meningitis, in pigs and in humans having occupational contact with pigs and pork, such as farmers, slaughterhose workers and butchers. The first stage of the pathogenic process, similar in pigs and humans, is adherence to and colonisation of mucosal and/or epithelial surface(s of the host. The second stage is invasion into deeper tissue and extracellular translocation of bacterium in the bloodstream, either free in circulation or attached to the surface of monocytes. If S. suis present in blood fails to cause fatal septicaemia, it is able to progress into the third stage comprising penetration into host’s organs, mostly by crossing the blood-brain barrier and/or blood–cerebrospinal fluid barrier to gain access to the central nervous system (CNS and cause meningitis. The fourth stage is inflammation that plays a key role in the pathogen esis of both systemic and CNS infections caused by S. suis . The pathogen may induce the overproduction of pro-inflammatory cytokines that cause septic shock and/or the recruitment and activation of different leukocyte populations, causing acute inflammation of the CNS. Streptococcus suis can also evoke – through activation of microglial cells, astrocytes and possibly other cell types – a fulminant inflammatory reaction of the brain which leads to intracranial complications, including brain oedema, increased intracranial pressure, cerebrovascular insults, and deafness, as a result of cochlear sepsis. In all stages of the pathogenic process, S. suis interacts with many types of immunocompetent host’s cells, such as polymorphonuclear leukocytes, mononuclear macrophages, lymphocytes, dendritic cells and microglia, using a range of versatile virulence factors for evasion of the innate and adaptive immune defence of the host, and for overcoming environmental stress. It is estimated that S. suis produces more than

    This article aims to define occupational rhinitis, classify its various causes, review the steps in its diagnosis, and describe its nonpharmacologic and pharmacologic principles of management. Occupational rhinitis frequently coexists with asthma but also occurs alone. Although it does not have the same impact as occupational asthma, occupational rhinitis causes distress, discomfort, and work inefficiency. By concentrating on the patient's workplace, the clinician has an opportunity to practice preventive medicine: to recognize substances in the patient's micro- and macroenvironment that are causing the problems and then to intervene by altering the environment or removing the patient from the environment.

    Wartime rape is an atrocity with long-lasting impacts not only on victims but whole societies. In this brief report, we present data on experience and witness of sexual violence during World War II (WWII) and subsequent time of occupation and on indicators of mental health in a sample of elderly Austrians. Interviews of 298 elderly Austrians from a larger epidemiological study on WWII traumatization were analyzed for the impact of experience and witness of sexual violence during the wartime committed by occupational forces. Interviews comprised a biographical/historical section and psychological measures (BSI, TLEQ, PCL-C). Participants were recruited in all nine provinces of Austria with respect to former zones of occupation (Western Allied/Soviet). Twelve persons reported direct experience of sexual violence, 33 persons witnessed such atrocities. One third of the victims and 18.2% of the witnesses reported post-traumatic stress disorder (PTSD full/subthreshold). Sexual violence occurred more often in the former Soviet zone. Victims and witnesses displayed higher odds of post-traumatic symptoms and symptoms of depression and phobic fear than non-victims. Furthermore, witnesses displayed higher levels of aggression compared to victims and non-witnesses. Our results corroborate previous findings that wartime rape has long-lasting effects over decades on current mental health and post-traumatic distress in victims and witnesses. We recommend integration of psychotraumatological knowledge on consequences of sexual violence on mental health into geriatric care and the education of dedicated personnel.

    This paper reviews the experience of the Workmen's Compensation Board of Ontario in identifying cases of cancer that could be attributed to occupational hazards. Workers' claims for compensation are allowed if there is reasonable medical evidence that their cancer was caused by exposure to risk factors associated with their occupation. Details of the types of cancers associated with specific carcinogens or fields of employment are discussed. About 50% of the cases were related to exposure in particular industrial operations that functioned for relatively brief periods. The number of deaths from cancer identified as being caused by occupational factors is compared with the total for cancer from all causes in Ontario during the period 1971 through 1975. Although all workers eligible for compensation may not have been identified, the data suggest that less than 1% is presently caused by occupational factors

    The apparent effect of ionizing radiation on lung cancer in A-bomb survivors has not been large enough to still doubts as to its validity. It has seemed essential to determine whether the apparent radiation effect could have resulted from a confounding of heavy smoking and high radiation dose, or if the occupational exposure of high-dose subjects with lung cancer was suggestive of the influence of environmental hazards other than radiation. The available series consists of 204 subjects with lung cancer verified by autopsy, 61 of whom were low-dose (less than 1 rad) and 13 high-dose (200+ rads) subjects. No evidence could be found that the influence of either smoking or occupational exposure upon lung cancer was exerted so as to suggest that the apparent radiation effect is other than real. The study also provides additional evidence of the relationship between lung cancer and smoking in Japan

    RNA polymerase II (Pol II) small nuclear RNA (snRNA) promoters and type 3 Pol III promoters have highly similar structures; both contain an interchangeable enhancer and "proximal sequence element" (PSE), which recruits the SNAP complex (SNAPc). The main distinguishing feature is the presence, in the type 3 promoters only, of a TATA box, which determines Pol III specificity. To understand the mechanism by which the absence or presence of a TATA box results in specific Pol recruitment, we examined how SNAPc and general transcription factors required for Pol II or Pol III transcription of SNAPc-dependent genes (i.e., TATA-box-binding protein [TBP], TFIIB, and TFIIA for Pol II transcription and TBP and BRF2 for Pol III transcription) assemble to ensure specific Pol recruitment. TFIIB and BRF2 could each, in a mutually exclusive fashion, be recruited to SNAPc. In contrast, TBP-TFIIB and TBP-BRF2 complexes were not recruited unless a TATA box was present, which allowed selective and efficient recruitment of the TBP-BRF2 complex. Thus, TBP both prevented BRF2 recruitment to Pol II promoters and enhanced BRF2 recruitment to Pol III promoters. On Pol II promoters, TBP recruitment was separate from TFIIB recruitment and enhanced by TFIIA. Our results provide a model for specific Pol recruitment at SNAPc-dependent promoters. © 2018 Dergai et al.; Published by Cold Spring Harbor Laboratory Press.

    Mediator plays an integral role in activation of RNA polymerase II (Pol II) transcription. A key step in activation is binding of Mediator to Pol II to form the Mediator-Pol II holoenzyme. Here, we exploit a combination of biochemistry and macromolecular EM to investigate holoenzyme assembly. We identify a subset of human Mediator head module subunits that bind Pol II independent of other subunits and thus probably contribute to a major Pol II binding site. In addition, we show that binding of human Mediator to Pol II depends on the integrity of a conserved “hinge” in the middle module MED21-MED7 heterodimer. Point mutations in the hinge region leave core Mediator intact but lead to increased disorder of the middle module and markedly reduced affinity for Pol II. These findings highlight the importance of Mediator conformation for holoenzyme assembly. PMID:27821593

    The International Classification of High-Resolution Computed Tomography (HRCT) for Occupational and Environmental Respiratory Diseases (ICOERD) is used to screen and diagnose respiratory illnesses. Using univariate and multivariate analysis, we investigated the relationship between subject characteristics and parenchymal abnormalities according to ICOERD, and the results of ventilatory function tests (VFT). Thirty-five patients with and 27 controls without mineral-dust exposure underwent VFT and HRCT. We recorded all subjects' occupational history for mineral dust exposure and smoking history. Experts independently assessed HRCT using the ICOERD parenchymal abnormalities (Items) grades for well-defined rounded opacities (RO), linear and/or irregular opacities (IR), and emphysema (EM). High-resolution computed tomography showed that 11 patients had RO; 15 patients, IR; and 19 patients, EM. According to the multiple regression model, age and height had significant associations with many indices ventilatory functions such as vital capacity, forced vital capacity, and forced expiratory volume in 1 s (FEV1). The EM summed grades on the upper, middle, and lower zones of the right and left lungs also had significant associations with FEV1 and the maximum mid-expiratory flow rate. The results suggest the ICOERD notation is adequate based on the good and significant multiple regression modeling of ventilatory function with the EM summed grades.

    Present working conditions in one of the most active areas of the maquiladora system along the Mexico-U.S. border are reminiscent of nineteenth-century U.S. sweatshops. The organization of production is Tayloristic and authoritarian, with detailed division of labor, repetitive simple tasks, and piecework wages. Modern participative management styles are not apparent in the maquiladora setting. This study consists of two separate but interrelated surveys conducted in 1992, one of community leaders and this one of workers in maquiladora enterprises in the towns of Matamoros and Reynosa, Mexico. The community survey evaluated the economic and psychosocial impact of the maquiladora enterprise and was conducted simultaneously to the workers' survey and in the same Mexican towns where the workers lived and worked. The community leaders acknowledged the employment opportunities that maquiladora factories had brought to the region but believed them to have high environmental and psychosocial costs. For the occupational component, a community-based survey of 267 maquiladora workers was conducted. participants were chosen with more than a year seniority in the industry and living in the two Mexican cities surveyed. They responded to an extensive questionnaire given by trained canvassers. The workers' survey found evidence that maquiladora workers (81% female) report symptoms from musculoskeletal disorders related to working conditions. Acute health effects compatible with chemical exposures were also identified. Prevalence of symptoms was correlated with increasing duration of exposure to ergonomic risk factors and qualitative chemical exposure indexes. Other chronic disease was not apparent. The survey demonstrated inequalities in salary, working hours, and safety training between the two communities. Matamoros workers are substantially better paid and work fewer hours per week than Reynosa workers. Most hazards reported in the worker's survey have been well studied in the

De modo geral os argumentos sobre o papel dos direitos humanos na política internacional dividem-se entre os que acham que eles não passam de retórica para encobrir interesses particulares, e os que enxergam na sua afirmação um potencial transformador da ordem internacional. No contexto atual,em que se discute a adoção de mecanismos coercitivos mais fortes para a proteção dos direitos humanos, como as intervenções humanitárias, por exemplo, essa discussão torna-se mais complexa e mais urgente.

  10. Relationship between RNA polymerase II and efficiency of vaccinia virus replication

    International Nuclear Information System (INIS)

    Wilton, S.; Dales, S.

    1989-01-01

    It is clear from previous studies that host transcriptase or RNA polymerase II (pol II) has a role in poxvirus replication. To elucidate the participation of this enzyme further, in this study the authors examined several parameters related to pol II during the cycle of vaccinia virus infection in L-strain fibroblasts, HeLa cells, and L 6 H 9 rat myoblasts. Nucleocytoplasmic transposition of pol II into virus factories and virions was assessed by immunofluorescence and immunoblotting by using anti-pol II immunoglobulin G. RNA polymerase activities were compared in nuclear extracts containing cured enzyme preparations. Rates of translation into cellular or viral polypeptides were ascertained by labeling with [ 35 S]methionine. In L and HeLa cells, which produced vaccinia virus more abundantly, the rate of RNA polymerase and translation in controls and following infection were higher than in myoblasts. The data on synthesis and virus formation could be correlated with observations on transmigration of pol II, which was more efficient and complete in L and HeLa cells. The stimulus for pol II to leave the nucleus required the expression of both early and late viral functions. On the basis of current and past information, the authors suggest that mobilization of pol II depends on the efficiency of vaccinia virus replication and furthermore that control over vaccinia virus production by the host is related to the content or availability (or both) of pol II in different cell types

    Accurate genetic information transfer is essential for life. As a key enzyme involved in the first step of gene expression, RNA polymerase II (Pol II) must maintain high transcriptional fidelity while it reads along DNA template and synthesizes RNA transcript in a stepwise manner during transcription elongation. DNA lesions or modifications may lead to significant changes in transcriptional fidelity or transcription elongation dynamics. In this review, we will summarize recent progress towards understanding the molecular basis of RNA Pol II transcriptional fidelity control and impacts of DNA lesions and modifications on Pol II transcription elongation.

  5. Human Pol ζ purified with accessory subunits is active in translesion DNA synthesis and complements Pol η in cisplatin bypass.

    Lee, Young-Sam; Gregory, Mark T; Yang, Wei

    2014-02-25

    DNA polymerase ζ (Pol ζ) is a eukaryotic B-family DNA polymerase that specializes in translesion synthesis and is essential for normal embryogenesis. At a minimum, Pol ζ consists of a catalytic subunit Rev3 and an accessory subunit Rev7. Mammalian Rev3 contains >3,000 residues and is twice as large as the yeast homolog. To date, no vertebrate Pol ζ has been purified for biochemical characterization. Here we report purification of a series of human Rev3 deletion constructs expressed in HEK293 cells and identification of a minimally catalytically active human Pol ζ variant. With a tagged form of an active Pol ζ variant, we isolated two additional accessory subunits of human Pol ζ, PolD2 and PolD3. The purified four-subunit Pol ζ4 (Rev3-Rev7-PolD2-PolD3) is much more efficient and more processive at bypassing a 1,2-intrastrand d(GpG)-cisplatin cross-link than the two-subunit Pol ζ2 (Rev3-Rev7). We show that complete bypass of cisplatin lesions requires Pol η to insert dCTP opposite the 3' guanine and Pol ζ4 to extend the primers.

  6. Rapid Genome-wide Recruitment of RNA Polymerase II Drives Transcription, Splicing, and Translation Events during T Cell Responses

    Kathrin Davari

    2017-04-01

    Full Text Available Summary: Activation of immune cells results in rapid functional changes, but how such fast changes are accomplished remains enigmatic. By combining time courses of 4sU-seq, RNA-seq, ribosome profiling (RP, and RNA polymerase II (RNA Pol II ChIP-seq during T cell activation, we illustrate genome-wide temporal dynamics for ∼10,000 genes. This approach reveals not only immediate-early and posttranscriptionally regulated genes but also coupled changes in transcription and translation for >90% of genes. Recruitment, rather than release of paused RNA Pol II, primarily mediates transcriptional changes. This coincides with a genome-wide temporary slowdown in cotranscriptional splicing, even for polyadenylated mRNAs that are localized at the chromatin. Subsequent splicing optimization correlates with increasing Ser-2 phosphorylation of the RNA Pol II carboxy-terminal domain (CTD and activation of the positive transcription elongation factor (pTEFb. Thus, rapid de novo recruitment of RNA Pol II dictates the course of events during T cell activation, particularly transcription, splicing, and consequently translation. : Davari et al. visualize global changes in RNA Pol II binding, transcription, splicing, and translation. T cells change their functional program by rapid de novo recruitment of RNA Pol II and coupled changes in transcription and translation. This coincides with fluctuations in RNA Pol II phosphorylation and a temporary reduction in cotranscriptional splicing.

    O'Connell, Allan F.; Bailey, Larissa L.; O'Connell, Allan F.; Nichols, James D.; Karanth, K. Ullas

    2011-01-01

    This chapter deals with the estimation of occupancy as a state variable to assess the status of, and track changes in, species distributions when sampling with camera traps. Much of the recent interest in occupancy estimation and modeling originated from the models developed by MacKenzie et al. (2002, 2003), although similar methods were developed independently (Azuma et al. 1990; Bayley and Petersen 2001; Nichols and Karanth, 2002; Tyre et al. 2003), all of which deal with species occurrence information and imperfect detection. Less than a decade after these publications, the modeling and estimation of species occurrence and occupancy dynamics have increased significantly. Special features of scientific journals have explored innovative uses of detection–nondetection data with occupancy models (Vojta 2005), and an entire volume has synthesized the use and application of occupancy estimation methods (MacKenzie et al. 2006). Reviews of the topical concepts, philosophical considerations, and various sampling designs that can be used for occupancy estimation are now readily available for a range of audiences (MacKenzie and Royle 2005; MacKenzie et al. 2006; Bailey et al. 2007; Royle and Dorazio 2008; Conroy and Carroll 2009; Kendall and White 2009; Hines et al. 2010; Link and Barker 2010). As a result, it would be pointless here to recast all that these publications have so eloquently articulated, but that said, a review of any scientific topic requires sufficient context and relevant background information, especially when relatively new methodologies and techniques such as occupancy estimation and camera traps are involved. This is especially critical in a digital age where new information is published at warp speed, making it increasingly difficult to stay abreast of theoretical advances and research developments.

  11. Characterization of Mycobacterium smegmatis PolD2 and PolD1 as RNA/DNA polymerases homologous to the POL domain of bacterial DNA ligase D.

    2012-12-21

    Mycobacteria exploit nonhomologous end-joining (NHEJ) to repair DNA double-strand breaks. The core NHEJ machinery comprises the homodimeric DNA end-binding protein Ku and DNA ligase D (LigD), a modular enzyme composed of a C-terminal ATP-dependent ligase domain (LIG), a central 3'-phosphoesterase domain (PE), and an N-terminal polymerase domain (POL). LigD POL is proficient at adding templated and nontemplated deoxynucleotides and ribonucleotides to DNA ends in vitro and is the catalyst in vivo of unfaithful NHEJ events involving nontemplated single-nucleotide additions to blunt DSB ends. Here, we identify two mycobacterial proteins, PolD1 and PolD2, as stand-alone homologues of the LigD POL domain. Biochemical characterization of PolD1 and PolD2 shows that they resemble LigD POL in their monomeric quaternary structures, their ability to add templated and nontemplated nucleotides to primer-templates and blunt ends, and their preference for rNTPs versus dNTPs. Deletion of polD1, polD2, or both from a Mycobacterium smegmatis strain carrying an inactivating mutation in LigD POL failed to reveal a role for PolD1 or PolD2 in templated nucleotide additions during NHEJ of 5'-overhang DSBs or in clastogen resistance. Whereas our results document the existence and characteristics of new stand-alone members of the LigD POL family of RNA/DNA polymerases, they imply that other polymerases can perform fill-in synthesis during mycobacterial NHEJ.

  16. [Attitudes of Polish occupational medicine physicians towards a proposal of requirements for occupational medicine training in Europe].

    Indulski, J A; Boczkowski, A; Mikulski, M

    1998-01-01

    In order to determine key competences required of occupational medicine specialists, common throughout Europe, a questionnaire has been developed and distributed among several European countries. The questionnaire contained 115 subjects related to 8 fields of activities carried out by occupational medicine physicians (occupational hazards to health, assessment of disability and fitness for work, communications, research methods, management, environmental medicine, occupational health law and ethics, and health promotion). In each of these fields, competences were classified into three following categories: knowledge, experience and skills. Respondents were asked to allocate a score from 0 to 5 for each subject, where 0 = not necessary; 1 = of minimum importance, and 5 = most important or essential. In Poland the questionnaire was distributed among two groups of specialists: group I--experienced specialists in occupational medicine (leading representatives of occupational health care management), and group II--relatively younger and less experienced occupational medicine physicians, participating in the specialist training, organised by The Nofer Institute of Occupational Medicine. A comprehensive analysis of the completed questionnaires was carried out in two dimensions: substantive (the importance of individual competences as perceived by Polish specialists in occupational medicine), and comparative (evaluation and interpretation of similarities and differences between two groups of respondents). A hierarchy of requirements, occupational medicine training in Poland is to satisfy, was reconstructed with two sets of competences, one recognised by respondents as needless and the other recognised as useful with different grades of importance. Some characteristic differences in opinions between two groups studies were highlighted.

    Mediator is a large, multisubunit complex that is required for essentially all mRNA transcription in eukaryotes. In spite of the importance of Mediator, the range of its targets and how it is recruited to these is not well understood. Previous work showed that in Saccharomyces cerevisiae, Mediator contributes to transcriptional activation by two distinct mechanisms, one depending on the tail module triad and favoring SAGA-regulated genes, and the second occurring independently of the tail module and favoring TFIID-regulated genes. Here, we use chromatin immunoprecipitation sequencing (ChIP-seq) to show that dependence on tail module subunits for Mediator recruitment and polymerase II (Pol II) association occurs preferentially at SAGA-regulated over TFIID-regulated genes on a genome-wide scale. We also show that recruitment of tail module subunits to active gene promoters continues genome-wide when Mediator integrity is compromised in med17 temperature-sensitive (ts) yeast, demonstrating the modular nature of the Mediator complex in vivo. In addition, our data indicate that promoters exhibiting strong and stable occupancy by Mediator have a wide range of activity and are enriched for targets of the Tup1-Cyc8 repressor complex. We also identify a number of strong Mediator occupancy peaks that overlap dubious open reading frames (ORFs) and are likely to include previously unrecognized upstream activator sequences.

    Full Text Available Abstract This editorial is to announce the Journal of Occupational Medicine and Toxicology, a new Open Access, peer-reviewed, online journal published by BioMed Central. Occupational medicine and toxicology belong to the most wide ranging disciplines of all medical specialties. The field is devoted to the diagnosis, prevention, management and scientific analysis of diseases from the fields of occupational and environmental medicine and toxicology. It also covers the promotion of occupational and environmental health. The complexity of modern industrial processes has dramatically changed over the past years and today's areas include effects of atmospheric pollution, carcinogenesis, biological monitoring, ergonomics, epidemiology, product safety and health promotion. We hope that the launch of the Journal of Occupational Medicine and Toxicology will aid in the advance of these important areas of research bringing together multi-disciplinary research findings.

    2004-10-01

    Skin cancer due to occupation is more common than is generally recognized, although it is difficult to obtain an accurate estimate of its prevalence. Over the past two centuries, occupational skin cancers have particularly been due to industrial exposure of men (it seems more so than women) to chemical carcinogens such as polycyclic hydrocarbons (e.g. from coal tar products) or to arsenic. Industrial processes have improved in most Western countries to limit this type of exposure, but those with outdoor occupations are still exposed to solar ultraviolet irradiation without this being widely recognized as an industrial hazard. Ionizing radiation such as X-rays can also cause skin cancer. Occupational skin cancers often resemble skin tumours found in non-occupational subjects, e.g. basal cell carcinoma, squamous cell carcinoma and malignant melanoma, but some pre-malignant lesions can be more specific and point to an occupational origin, e.g. tar keratoses or arsenical keratoses. An uncommon but well-recognized cause of occupational skin cancer is that which results from scar formation following an industrial burn. In the future it will be necessary to focus on preventative measures, e.g. for outdoor workers, the need to cover up in the sun and use sun protective creams and a campaign for earlier recognition of skin cancers, which are usually curable if treated in their early stages.

    The aim of the present study was to investigate the prevalence of burnout and occupational participation limitation among dental students in a dental school in Turkey. Four hundred fifty-eight dental students (females=153; males=305) were included in the study. The age range varied from 17-to-38 years. Maslach Burnout Inventory-Student Version (MBI-SV) and Canadian Occupational Performance Measure (COPM) were used to gather data. Descriptive analyses, t-test, and Kruskall-Wallis test for independent groups were used for data analyses. The results indicated that 26% of all the students have burnout in terms of emotional exhaustion (25%), cynicism (18%), and academic efficacy (14%). The results showed that burnout is statistically significant in relation to demographics (pstudents showed considerably decreased occupational performance and satisfaction scores, which suggested occupational participation limitations. Occupational performance and satisfaction scores were inversely correlated with emotional exhaustion and cynicism, while directly correlated with reduced academic efficacy (pburnout and occupational participation limitation can be seen among dental students. Students with burnout may also have occupational participation limitation. Enriching dental education programs with different psychological strategies may be useful for education of healthy dentists and improve the quality of oral and dental health services.

    Full Text Available Hasta la publicación de Sobre la esencia y el valor de la democracia, Hans Kelsen era solo conocido como experto en derecho público. El valor de este artículo de Lagi radica en rescatar de la obra kelseniana un aspecto casi por completo olvidado por la crítica, a saber, sus análisis sobre el significado y las características de la democracia parlamentaria en los Estados modernos. Se aborda la cuestión no solo desde el debate teórico sino también desde su contexto histórico¿político. La teoría política de Kelsen es considerada una parte integral de su doctrina central, presentada en Teoría pura del derecho, su obra más conspicua. Un análisis del trabajo sobre la esencia y el valor de la democracia nos restituye la imagen de un Kelsen como original pensador político. Se analizan las dos ediciones de Sobre la esencia y el valor de la democracia (1920¿1929 con estos propósitos: comprender por qué decidió dedicarse a la teoría de la democracia un teórico que rigurosamente defendió la separación de la esfera jurídica respecto de la historia, la filosofía y la política; y por qué no se limitó a explicar la esencia de la democracia sino que decidió concentrarse en clarificar qué se entiende por valor de la democracia.

  17. Workplace Congruence and Occupational Outcomes among Social Service Workers.

    Graham, John R; Shier, Micheal L; Nicholas, David

    2016-06-01

    Workplace expectations reflect an important consideration in employee experience. A higher prevalence of workplace congruence between worker and employer expectations has been associated with higher levels of productivity and overall workplace satisfaction across multiple occupational groups. Little research has investigated the relationship between workplace congruence and occupational health outcomes among social service workers. This study sought to better understand the extent to which occupational congruence contributes to occupational outcomes by surveying unionised social service workers ( n = 674) employed with the Government of Alberta, Canada. Multiple regression analysis shows that greater congruence between workplace and worker expectations around workloads, workplace values and the quality of the work environment significantly: (i) decreases symptoms related to distress and secondary traumatic stress; (ii) decreases intentions to leave; and (iii) increases overall life satisfaction. The findings provide some evidence of areas within the workplace of large government run social welfare programmes that can be better aligned to worker expectations to improve occupational outcomes among social service workers.

    2014-06-01

    A collaborative approach with teachers is required when providing community-based occupational therapy to educationally at risk children. Collaborators share common goals and interact and support each other but challenges arise in providing collaborative occupational therapy in settings outside the school environment. The aim of this study was to capture experiences of teachers and occupational therapists working within a school-based occupational therapy program to determine if their experiences could inform collaborative practice. In this pilot study, participant responses to questionnaires (n = 32) about their experiences formed the basis for focus groups and individual interviews. Two focus group were conducted, one with teachers (n = 11) and one with occupational therapy participants (n = 6). Individual interviews were conducted with the supervising occupational therapist, school principal and two leading teachers. Descriptive statistics were used to analyse the data from closed questions, and thematic analysis using a constant comparison approach was used to analyse open ended questions, focus groups and interviews. Three main themes emerged: (i) the need for occupational therapists to spend time in the school, to explain their role, build relationships, understand classroom routines and the teacher role; (ii) occupational therapists need to not see themselves as the expert but develop equal partnerships to set collaborative goals and (iii) occupational therapists advocating for all parties to be informed throughout the occupational therapy process. The pilot study findings identified teacher and therapist experiences within the school setting that could inform improved collaborative practice with teachers and community-based occupational therapists and these findings warrant further investigation. © 2013 Occupational Therapy Australia.

    1997-01-01

    Brazil is a recently industrialised country with marked contrasts in social and economic development. The availability of public/private services in its different regions also varies. Health indicators follow these trends. Occupational health is a vast new field, as in other developing countries. Occupational medicine is a required subject in graduation courses for physicians. Specialisation courses for university graduated professionals have more than 700 hours of lectures and train occupational health physicians, safety engineers and nursing staff. At the technical level, there are courses with up to 1300 hours for the training of safety inspectors. Until 1986 about 19,000 occupational health physicians, 18,000 safety engineers and 51,000 safety inspectors had been officially registered. Although in its infancy, postgraduation has attracted professionals at university level, through residence programmes as well as masters and doctors degrees, whereby at least a hundred good-quality research studies have been produced so far. Occupational health activities are controlled by law. Undertakings with higher risks and larger number of employees are required to hire specialised technical staff. In 1995 the Ministry of Labour demanded programmes of medical control of occupational health (PCMSO) for every worker as well as a programme of prevention of environmental hazards (PPRA). This was considered as a positive measure for the improvement of working conditions and health at work. Physicians specialising in occupational medicine are the professionals more often hired by the enterprises. Reference centres (CRSTs) for workers' health are connected to the State or City Health Secretariat primary health care units. They exist in more populated areas and are accepted by workers as the best way to accomplish the diagnosis of occupational diseases. There is important participation by the trade unions in the management of these reference centres. For 30 years now employers

  16. Política, violencia y literatura

    2002-06-01

    Full Text Available Tomando como punto de partida la opinión general de que América Latina es el continente violento por excelencia y la hipótesis defendida por Ariel Dorfman (1972 se analiza aquí la cuestión de la violencia política, ciñéndose a la literatura de la segunda mitad del siglo XX. Tras discutir las definiciones (divergentes de la violencia propuestas por la filosofía política, se pasa a una fenomenología de la violencia en la literatura, examinando hasta qué punto y en qué sentido ésta sería el carácter distintivo de la literatura latinoamericana. Finalmente, se analiza la metarreflexión sobre la violencia política en la literatura ficcional, centrándose en tres puntos: (1 el (presunto ser violento del mundo latinoamericano, (2 la violencia estatal, y (3 la violencia de la resistencia. Se constata, entre otras cosas, que ha habido una tendencia a atacar la violencia estatal y defender la de la resistencia; tendencia comprensible en tiempos de dictadura, pero que se vuelve problemática bajo una democracia. Dos preguntas cierran este trabajo: hasta qué punto la violencia es un fenómeno de la cultura, que crece en su mismo seno, y no un fenómeno extracultural dirigido contra ella, y hasta dónde la libertad individual y la seguridad cívica pueden ser conciliadas, punto que ha ocupado un lugar central en la discusión internacional después de los acontecimientos del 11 de septiembre.

  19. Amor y política.

    Directory of Open Access Journals (Sweden)

    Hernando Bernal.

    1998-09-01

    Full Text Available Este trabajo pretende hacer una serie de consideraciones que apuntan sobre todo a extraer una definición de lo que es «la política» para el psicoanálisis a partir de una observación que hace Jacques Alain Miller en su texto Lógicas de la vida amorosa sobre cómo Freud introduce una «teoría política» a partir de su texto Psicología de las masas y análisis del yo.En dicho texto Freud hace ver el poder ordenador y apaciguador del amor significante amo en la medida en que una masa no es más que el amor uniendo a muchas personas y reiterado en cada una de ellas. Las fuerzas armadas y la Iglesia son un buen ejemplo de ello.Pero a pesar de la cohesión amorosa de la humanidad por el poder unificante del amor, resta siempre un malestar. El malestar que persiste en la cultura testimonia del fracaso del amor para resolver el empuje del hombre a satisfacerse con el mal. El significante amo no parece entonces solucionar la paradoja del goce. De aquí que preguntarse sobre adónde vaya el goce en el orden social sea también, para el psicoanálisis, una cuestión política. Jacques- Alain Miller observa, en su texto Lógicas de la vida amorosa, cómo, a partir de la Psicología de las masas y análisis del yo, se puede extraer de Freud una «teoría política», que se vincula muy estrechamente con el amor. Esto porque La Psicología de las masas... enseña sobre el poder ordenador y apaciguador del amor, o mejor, del significante «amor» como significante Amo, lo que se puede escribir de la siguiente manera con ayuda de la «teoría de los discursos» o «teoría del vínculo social» de Lacan.

    The proceedings contain the 29 papers presented at the conference plus the opening address from the chair of the Health and Safety Commission. The papers in the first session were concerned with policy, strategy and leadership and included a perspective from the offshore industry advisory committee, details of a health planning tool for occupational health assurance and lessons from occupational health management in the offshore sector. The two sessions on the second day dealt with occupational health in the offshore design process and case studies involving physical, chemical and biological agents. Topics included the need to consider occupational health when designing offshore installations, the development of a human factors engineering strategy in petrochemical engineering projects, measuring occupational exposure to hazardous chemicals, implementation of the noise at work regulations, hand arm vibration syndrome and issues with potable water maintenance. The two sessions on the third day were concerned with human factors and psychological health, and well-being and fitness for duty. Topics covered included circadian adaption to shift change in offshore shift workers, managing stress in the offshore environment, the role of employee assistance programmes in organisational stress management, health care and first aid (the revised ACOP), well-being at work, the medical and physical fitness of offshore emergency response rescue team members, the impact of health surveillance and promotion of offshore accident rates, and the implication of safety and heath of the aging of the workforce ion the Norwegian offshore industry.

    Full Text Available Zoonoses are discussed as occupational diseases, with special reference to animal husbandry and related activities. After quoting some historical references, occupational zoonoses are examined in relation to the evolution of the concept of occupational zoonosis, the involvement of the World Health Organization in this field, their socio-economic significance, the principal working activities, zoonoses of greatest importance (with special reference to the Mediterranean region, the evaluation of damage and risks. An outline is made of the transmission of zoonoses from farm workers to animals and the biological hazards from the environment. The present situation of occupational zoonoses and related risks in industrialised and traditional farming activities are presented and the importance of some emerging and re-emerging zoonoses for the health of workers is highlighted. The author concludes by stressing that the prevention of occupational zoonoses must be implemented jointly by both veterinary and medical services through preventive measures and epidemiological surveillance of human and animal health, risk evaluation, diagnosis of infections and prompt reporting. It is hoped that the future will offer better inter-disciplinary collaboration and that legislation will be timely and better tailored to safeguard working health and safety.

Fraser, 1999; Honnetch, 2003 entre as tradicionais políticas de redistribuição sócio-econômica, e uma nova diretriz de reconhecimento das diferenças sócio-políticas e culturais. O argumento retoma a trajetória sindical do PT e os efeitos das políticas participativas, nas mudanças da cultura política em várias partes do país. Entre esses efeitos, o crescente apoio à democracia parece relacionar-se ao reconhecimento do direito à diferença e ao pluralismo - principalmente entre a juventude e naqueles locais onde o PT tem governado na última década

  3. Proviral HIV-genome-wide and pol-gene specific zinc finger nucleases: usability for targeted HIV gene therapy.

    2011-07-22

    Infection with HIV, which culminates in the establishment of a latent proviral reservoir, presents formidable challenges for ultimate cure. Building on the hypothesis that ex-vivo or even in-vivo abolition or disruption of HIV-gene/genome-action by target mutagenesis or excision can irreversibly abrogate HIV's innate fitness to replicate and survive, we previously identified the isoschizomeric bacteria restriction enzymes (REases) AcsI and ApoI as potent cleavers of the HIV-pol gene (11 and 9 times in HIV-1 and 2, respectively). However, both enzymes, along with others found to cleave across the entire HIV-1 genome, slice (SX) at palindromic sequences that are prevalent within the human genome and thereby pose the risk of host genome toxicity. A long-term goal in the field of R-M enzymatic therapeutics has thus been to generate synthetic restriction endonucleases with longer recognition sites limited in specificity to HIV. We aimed (i) to assemble and construct zinc finger arrays and nucleases (ZFN) with either proviral-HIV-pol gene or proviral-HIV-1 whole-genome specificity respectively, and (ii) to advance a model for pre-clinically testing lentiviral vectors (LV) that deliver and transduce either ZFN genotype. First, we computationally generated the consensus sequences of (a) 114 dsDNA-binding zinc finger (Zif) arrays (ZFAs or ZifHIV-pol) and (b) two zinc-finger nucleases (ZFNs) which, unlike the AcsI and ApoI homeodomains, possess specificity to >18 base-pair sequences uniquely present within the HIV-pol gene (ZifHIV-polFN). Another 15 ZFNs targeting >18 bp sequences within the complete HIV-1 proviral genome were constructed (ZifHIV-1FN). Second, a model for constructing lentiviral vectors (LVs) that deliver and transduce a diploid copy of either ZifHIV-polFN or ZifHIV-1FN chimeric genes (termed LV- 2xZifHIV-polFN and LV- 2xZifHIV-1FN, respectively) is proposed. Third, two preclinical models for controlled testing of the safety and efficacy of either of these

    The workplace is a key setting where gender issues and organizational structures may influence occupational health and safety practices. The enactment of dominant norms of masculinity in high risk occupations can be particularly problematic, as it exposes men to significant risks for injuries and fatalities. To encourage multi-disciplinary collaborations and advance knowledge in the intersecting areas of gender studies, men's health, work and workplace health and safety, a national network of thirteen researchers and health and safety stakeholders completed a critical literature review examining the intersection between masculinities and men's workplace health and safety in order to: (i) account for research previously undertaken in this area; (ii) identify themes that may inform our understanding of masculinity and workplace health and safety and; (iii) identify research and practice gaps in relation to men's workplace health and safety. In this paper we present key themes from this review. Recommendations are made regarding: (i) how to define gender; (ii) how to attend to and identify how masculinities may influence workers' identities, perceptions of occupational risks and how institutionalized practices can reinforce norms of masculinity; (iii) the importance of considering how masculinities may intersect with other variables (e.g. historical context, age, class, race, geographical location) and; (iv) the added significance of present-day labour market forces on men's occupational health and safety.

    1995-10-01

    A study was conducted to show the problem of occupational injuries in Bahrain and try to highlight some solutions that may help to prevent or reduce workplace hazards. The data for occupational injuries between 1988 to 1991 from the social insurance records were reviewed and analysed. The data were summarized, grouped and tabulated according to age, sex, nationality, work place, type of injuries, cause and site of injury. Data were analysed statistically, frequencies were computed and results represented graphically. The study shows that there was a decline in the number of injuries in 1990 and 1991 due to a slow-down of economic activities in general in the Arabian Gulf region during the Gulf War. It also shows that Asian workers are at a high risk of occupational injuries.

On the other hand residues with low modification level can be dramatically affected by mild oxidative imbalance. We make use of high resolution mass...... peptides corresponding to 90 proteins. Only 6 modified peptides changed significantly under mild oxidative stress. Quantitative information allowed us to determine relative modification site occupancy of each identified modified residue and pin point heavily modified ones.

  8. Croce, Gramsci e a "autonomia da política"

    Directory of Open Access Journals (Sweden)

    Álvaro Bianchi

    2007-11-01

    Full Text Available Na reflexão que Gramsci desenvolveu nos Quaderni del carcere, o tema da autonomia da política ocupa uma importante posição. Foi com base nessa reflexão que Gramsci desenvolveu sua pesquisa a respeito de política e da possibilidade de uma ciência política. Segundo Benedetto Croce, cabia a Nicolau Maquiavel o mérito de ter afirmado pela primeira vez a autonomia da política. Para Croce, essa autonomia permitia estabelecer uma distinção radical entre ética e política e entre "filosofia da política" e "ciência empírica da política". Gramsci tomou criticamente a reflexão croceana como ponto de partida de sua leitura de Maquiavel. O reconhecimento da autonomia da política implicava que esta não poderia ser reduzida à religião ou à ética. Como campo do conhecimento e como atividade, a ciência política e a política tinham regras próprias, que as distinguiam de outras formas do conhecimento e da atividade humana. Mas tal "autonomia" não implicava, para o marxista sardo, uma separação radical entre política e moral. Por essa razão, Gramsci encontrava em Maquiavel um precursor da filosofia da práxis em sentido pleno, ou seja, o criador de uma "ciência-ação revolucionária".

    The potentially harmful effects on women of certain workplace exposures are widely appreciated, and steps to control these have included legislative efforts such as right-to-know laws of well as corporate policies mandating selective restriction of fertile women, which are illegal under federal civil rights laws. This chapter reviews the various occupational health risks reproductive women face in the workplace but also considers the effects of other genetic, medical, social, infectious, and environmental factors which may be of even greater concern than most occupational factors.

  16. Human PrimPol activity is enhanced by RPA.

    Science.gov (United States)

    Martínez-Jiménez, María I; Lahera, Antonio; Blanco, Luis

    2017-04-10

    Human PrimPol is a primase belonging to the AEP superfamily with the unique ability to synthesize DNA primers de novo, and a non-processive DNA polymerase able to bypass certain DNA lesions. PrimPol facilitates both mitochondrial and nuclear replication fork progression either acting as a conventional TLS polymerase, or repriming downstream of blocking lesions. In vivo assays have shown that PrimPol is rapidly recruited to sites of DNA damage by interaction with the human replication protein A (RPA). In agreement with previous findings, we show here that the higher affinity of RPA for ssDNA inhibits PrimPol activities in short ssDNA templates. In contrast, once the amount of ssDNA increases up to a length in which both proteins can simultaneously bind ssDNA, as expected during replicative stress conditions, PrimPol and RPA functionally interact, and their binding capacities are mutually enhanced. When using M13 ssDNA as template, RPA stimulated both the primase and polymerase activities of PrimPol, either alone or in synergy with Polε. These new findings supports the existence of a functional PrimPol/RPA association that allows repriming at the exposed ssDNA regions formed in the leading strand upon replicase stalling.

    Directory of Open Access Journals (Sweden)

    ANDRÉ NASSIF

    2015-09-01

    Full Text Available RESUMOEste artigo analisa o chamado tripé da política macroeconômica brasileira, que desde 1999 tem combinado um regime de metas de inflação, um regime de taxa de câmbio flutuante e metas de superávit fiscal primário. A menos que o seu modus operandi seja alterado, o tripé não será capaz de libertar a economia brasileira de outra "possível trindade": altas taxas de juros reais, a apreciação da taxa de câmbio real e crescimento econômico muito baixo. Depois de analisar brevemente a base teórica sob o tripé macroeconômico, o artigo mostra por que este regime de política macroeconômica, se avaliado numa perspectiva de longo ou médio prazo, não tem sido capaz de garantir a estabilidade dos preços nem o crescimento econômico. Além da sugestão de romper com a estratégia brasileira de crescer com poupança externa, o documento também sugere três principais formas de mudar o modus operandi do tripé brasileiro: i aumentar o horizonte de tempo para atingir a meta de inflação, como tem sido o experiência da maioria dos países que adotam esse regime de política monetária; ii restaurar o papel anticíclico da política fiscal brasileira; e iii adotar uma combinação de mecanismos que visem prevenir que a moeda brasileira entre em uma nova tendência cíclica da apreciação em termos reais.

    Full text: The ESOREX project was initiated by the European Commission in 1997. The objectives of this European study are: to provide the European Commission and the national competent radiation protection authorities with reliable information on how personal radiation monitoring, reporting and recording of dosimetric results is organized in European countries; to collect reliable and directly comparable data on individual and collective radiation exposure in all occupational sectors where radiation workers are employed. The information about the monitoring of occupational radiation exposure, the levels of individual personal doses of workers in the different work sectors, the changes and trends of these doses over a period of several years and the international comparison of these data are useful information for many stakeholders. The survey consists of two parts. Part I surveys how radiation protection monitoring, recording and reporting is arranged within each of the 30 European countries. Part II collects doses from occupational exposure of classified workers in the participating countries. For each country, information is provided on the number of workers in defined work categories and how annual individual personal doses are distributed. The summary and the conclusions provide tentative recommendations for harmonizing modifications of some of the national monitoring, reporting and recording arrangements. In all ESOREX studies a beneficial, effective and extensive information base about thirty European states has been created. The studies resulted in country reports describing the legislative, administrative, organizational and technical aspects of the national dose monitoring and recording systems for occupationally radiation exposed workers. These reports are standardized, i.e. they have as far as possible an internationally comparable structure.

    Eklund, Mona; Argentzell, Elisabeth

    2016-07-01

    Aims The aims were to (i) investigate initial construct validity of a tool for assessment of time allocation in occupational balance, and (ii) describe perceived occupational balance and its relationship with socio-demographics, well-being, and personal recovery among people with mental illness. Methods Satisfaction with Daily Occupations and Occupational Balance (SDO-OB) was administered to 226 persons. SDO-OB reflects balance in five occupational domains: work, leisure, home chores, self-care, and overall occupational balance. Indicators for assessing construct validity were: satisfaction with everyday occupations, occupational value, symptom severity, and psychosocial functioning. For the second aim, the data collection included socio-demographics, life quality, self-esteem, self-mastery, and personal recovery. Results Occupational balance ratings indicated the participants were either under-occupied or in balance. Few were over-occupied. Feeling in balance was related to greater well-being and recovery compared with being under-occupied. Risk factors for under-occupation were younger age (in relation to work), and higher education (in relation to overall balance). Conclusions Associations with the indicators suggest initial construct validity. The SDO-OB is promising for assessment of occupational balance among people with mental illness. Being under-occupied was detrimental to well-being and recovery, and this indicates the importance of offering more occupational opportunities for people with mental illness.

In a monocentric retrospective study, from our database, only 31 (0.41%) of patients with contact dermatitis had positive skin tests with proteins: 22 had occupational PCD, 3 had non-occupational PCD, 5 occupational ICU and 1 cook had a neutrophilic fixed food eruption (NFFE) due to fish. From these results and analysis of literature, the characteristics of PCD can be summarized as follows. It is a chronic eczematous dermatitis, possibly exacerbated by work, suggestive if associated with inflammatory perionyxix and immediate erythema with pruritis, to be investigated when the patient resumes work after a period of interruption. Prick tests with the suspected protein-containing material are essential, as patch tests have negative results. In case of multisensitisation revealed by prick tests, it is advisable to analyse IgE against recombinant allergens. A history of atopy, found in 56 to 68% of the patients, has to be checked for. Most of the cases are observed among food-handlers but PCD can also be due to non-edible plants, latex, hydrolysed proteins or animal proteins. Occupational exposure to proteins can thus lead to the development of ICU. Reflecting hypersensitivity to very low concentrations of allergens, investigating ICU therefore requires caution and prick tests should be performed with a diluted form of the causative protein-containing product. Causes are food, especially fruit peel, non-edible plants, cosmetic products, latex, animals.

    Venezuela has pioneered a preventive-focused and comprehensive movement for Occupational Safety and Health (OSH) in Latin America. However, despite being an oil-rich country, it has some of the lowest salaries for their workers and highest levels of hyperinflation, devaluation, crime, and violence of the world. Review the current status and challenges on relevant aspects of OSH in Venezuela. Review of literature and documents from national governments, UN agencies, NGOs, and the Venezuelan government concerning OSH and related topics since 1986. Reformed in 2005, the Organic Law on Prevention, Conditions and Environment (LOPCYMAT) was a fundamental moment of change for OSH. Factors which have impacted OSH the strongest are (i) the creation of the National Institute of Occupational Safety and Health (INPSASEL) and (ii) the socioeconomic crisis Venezuela is going through. Venezuela's laws are innovative and yet non-compliance is enormous. Almost half of the population works in the informal sector. Following the International Labor Office projections, 5 people die per day in Venezuela due to occupational accidents or diseases, making health and safety at work a luxury rather than a right. The quality of life for the average worker has deteriorated, affecting not only health but the overall well-being of all Venezuelans. The political and socio-economic situation has led to a mass exodus of more than 1.6 million highly qualified and talented professionals. Many statistics concerning OSH are not updated and are unreliable regarding occupational accidents and diseases. There is a substantial difference between what is written to protect individual Venezuelans in the workplace and the reality of workplace conditions. Substantial governmental actions are needed in the immediate future to improve occupational safety and health of Venezuelan workers. Copyright © 2015 The Author. Published by Elsevier Inc.

Em razão da eficácia de seu carisma institucional, a Universal procedeu, dentro do próprio grupo religioso, a uma ressemantização do ato de votar em particular e da percepção da política em geral, inscrevendo-os em sua lógica religiosa. Isso é uma importante chave explicativa para o elevado grau de fidelidade de votos e o êxito político cada vez maior constatado nas últimas eleições. Ademais, a prática política da Universal está produzindo um efeito mimético em outra igrejas evangélicas, que tendem a imitar seu modelo de fazer política. Sua inserção política, sobretudo por intermédio do Partido Liberal, não passa despercebida pelos partidos, constituindo-se, assim, em um ator relevante na atual conjuntura política brasileira.

    Purpose: The purpose of this paper is to examine the dynamic relationship between policies related to educational provision and both educational participation and occupational outcomes in Brazil, using PNAD and RAIS-Migra data. Design/methodology/approach: Outcomes are examined using: static...... multinomial logit analysis, and structural dynamic discrete choice modelling. The latter approach, coupled with the quality of the RAIS-Migra data source, allows the authors to evaluate the education policy impacts over time. Findings: The main results show that the education level raises the propensity...... that the individual will be in formal sector work or still in education, and reduces the probability of the other outcomes. Transition into non-manual formal sector work following education may, however, occur via a spell of manual work. Originality/value: This is the first study of occupational destination...

    2005-01-01

    The revision process of the international radiological protection regulations has resulted in the adoption of new concepts, such as practice, intervention, avoidable and restriction of dose (dose constraint). The latter deserving of special mention since it may involve reducing a priori of the dose limits established both for the public and to individuals occupationally exposed, values that can be further reduced, depending on the application of the principle of optimization. This article aims to present, with clarity, from the criteria adopted to define dose constraint values to the public, a methodology to establish the dose constraint values for occupationally exposed individuals, as well as an example of the application of this methodology to the practice of industrial radiography

    Background: Motivation is one of the most important factors for safety behaviour and for implementing change in general. However, theoretical and psychometric studies of safety performance have traditionally treated safety motivation, safety compliance and safety participation unidimensionally....... At the same time many motivation questionnaire items are seldom founded on theory and/or do not account for the theories’ ontological and epistemological differences, e.g. of how knowledge, attitude and action are related. Present questionnaire items tap into occupational safety motivation in asking whether...... or not respondents ‘are’ motivated and whether they feel that safety is important or worthwhile. Another important aspect is ‘what’ motivates workers to comply to and participate in safety. The aim of this article is to introduce a new theory-based occupational safety motivation scale which is validated...

    Full Text Available Jen Gash, an occupational therapist and creativity coach living in the UK, provided the cover art for the winter 2015 issue of The Open Journal of Occupational Therapy. The picture is titled “Over the Exe.” Jen uses her inspiration of the Kawa River model in this painting. The painting is of her husband and daughter standing where the river meets the sea. This is a metaphoric representation of rejoining the greater collective. In addition, Jen has a passion for occupational therapists to encompass creativity. A core aspect of occupational therapy is the multi-dimensional concept of occupations; it allows for occupational therapists to incorporate creativity into daily practice. Jen’s goal is for occupational therapy to embrace its creative theoretical roots.

  5. Perspective on occupational mortality risks

    International Nuclear Information System (INIS)

    Cohen, B.L.

    1981-01-01

    Occupational risks to radiation workers are compared with other occupational risks on the basis of lost life expectancy (LLE) in a full working lifetime. Usual comparisons with National Safety Council accident death statistics for various industry categories are shown to be unfair because the latter average over a variety of particular industries and occupations within each industry. Correcting for these problems makes some common occupations in some industries 20-50 times more dangerous due to accidents alone than being a radiation worker. If more exposed subgroups of radiation workers are compared with more dangerous subgroups of other occupations, these ratios are maintained. Since radiation causes disease rather than acute injury, a wide range effort is made to estimate average loss of life expectancy from occupational disease; the final estimate for this is 500 days. The average American worker loses more than an order of magnitude more life expectancy from occupational disease than the average radiation worker loses from radiation induced cancer. (author)

    2001-03-01

    Occupational ocular trauma is an important cause of acquired monocular blindness in a rapidly industrialising country like India. Knowledge of the epidemiology of occupational eye injuries is essential to formulate viable industrial safety measures. We retrospectively reviewed all patients with occupational open globe injuries between 1994 and 1998. We documented the circumstances of the injuries, their clinical findings and the use of appropriate protective eyewear at the time of the injury. The visual acuity 6 months after the injury was the final outcome measure. In this study period we examined 43 patients with open globe injuries sustained at the work place. Thirty-four (79.1%) patients were young males. The iron and steel industry accounted for 19 (44.2%) cases while 8 (18.6%) patients each were from the agricultural, mining and other small scale industrial sectors. At the time of the injury, 33 (76.7%) were not wearing the recommended protective eyewear and 6 (13.9%) were under the influence of alcohol. The injuries were mild in 6 (13.9%), moderate in 18 (41.9%) and severe in 19 (44.2%) patients. At the end of 6 months, 2 (4.7%) patients had a visual acuity of 6/12 or better, 4 (9.3%) had a visual acuity of 6/18 to 6/60 and 29 (67.4.%) had a vision of eyewear and alcohol-free environment at the work place is likely to reduce the incidence of severe occupational open globe injuries.

  7. PREVENTION OF OCCUPATIONAL ACCIDENTS

    Directory of Open Access Journals (Sweden)

    Jovica Jovanovic

    2004-01-01

    Full Text Available Medical services, physicians and nurses play an essential role in the plant safety program through primary treatment of injured workers and by helping to identify workplace hazards. The physician and nurse should participate in the worksite investigations to identify specific hazard or stresses potentially causing the occupational accidents and injuries and in planning the subsequent hazard control program. Physicians and nurses must work closely and cooperatively with supervisors to ensure the prompt reporting and treatment of all work related health and safety problems. Occupational accidents, work related injuries and fatalities result from multiple causes, affect different segments of the working population, and occur in a myriad of occupations and industrial settings. Multiple factors and risks contribute to traumatic injuries, such as hazardous exposures, workplace and process design, work organization and environment, economics, and other social factors. With such a diversity of theories, it will not be difficult to understand that there does not exist one single theory that is considered right or correct and is universally accepted. These theories are nonetheless necessary, but not sufficient, for developing a frame of reference for understanding accident occurrences. Prevention strategies are also varied, and multiple strategies may be applicable to many settings, including engineering controls, protective equipment and technologies, management commitment to and investment in safety, regulatory controls, and education and training. Research needs are thus broad, and the development and application of interventions involve many disciplines and organizations.

    In the period of transition from a centralized economy to the market economy, occupational health services in Kyrgyzstan have survived through dramatic, detrimental changes. It is common for occupational health regulations to be ignored and for basic occupational health services across many industrial enterprises and farms to be neglected. The aim of this study was to demonstrate the present situation and challenges facing occupational health services in Kyrgyzstan. The transition from centralized to the market economy in Kyrgyzstan has led to increased layoffs of workers and unemployment. These threats are followed by increased workload, and the health and safety of workers becomes of little concern. Private employers ignore occupational health and safety; consequently, there is under-reporting of occupational diseases and accidents. The majority of enterprises, especially those of small or medium size, are unsanitary, and the health status of workers remains largely unknown. The low official rates of occupational diseases are the result of data being deliberately hidden; lack of coverage of working personnel by medical checkups; incompetent management; and the poor quality of staff, facilities, and equipment. Because Kyrgyzstan is a mountainous country, the main environmental and occupational factor of enterprises is hypoxia. Occupational health specialists have greatly contributed to the development of occupational medicine in the mountains through science and practice. The enforcement of existing strong occupational health legislation and increased financing of occupational health services are needed. The maintenance of credible health monitoring and effective health services for workers, re-establishment of medical services and sanitary-hygienic laboratories in industrial enterprises, and support for scientific investigations on occupational risk assessment will increase the role of occupational health services in improving the health of the working population

  12. Comparison of the CAS-POL and IOM samplers for determining the knockdown efficiencies of water sprays on float coal dust.

    Seaman, Clara E; Shahan, Michael R; Beck, Timothy W; Mischler, Steven E

    2018-03-01

    Float coal dust, generated by mining operations, is distributed throughout mine airways by ventilating air designed to purge gases and respirable dust. Float coal dust poses an explosion hazard in the event of a methane ignition. Current regulation requires the application of inert rock dust in areas subjected to float coal dust in order to mitigate the hazard. An alternate method using water sprays, which have been effective in controlling respirable dust hazards, has been proposed as a way to control float coal dust generated on longwall faces. However, the knockdown efficiency of the proposed water sprays on float coal dust needs to be verified. This study used gravimetric isokinetic Institute of Occupational Medicine (IOM) samplers alongside a real-time aerosol monitor (Cloud Aerosol Spectrometer with polarization; CAS-POL) to study the effects of spray type, operating pressure, and spray orientation on knockdown efficiencies for seven different water sprays. Because the CAS-POL has not been used to study mining dust, the CAS-POL measurements were validated with respect to the IOM samplers. This study found that the CAS-POL was able to resolve the same trends measured by the IOM samplers, while providing additional knockdown information for specific particle size ranges and locations in the test area. In addition, the CAS-POL data was not prone to the same process errors, which may occur due to the handling of the IOM filter media, and was able to provide a faster analysis of the data after testing. This study also determined that pressure was the leading design criteria influencing spray knockdown efficiency, with spray type also having some effect and orientation having little to no effect. The results of this study will be used to design future full-scale float coal dust capture tests involving multiple sprays, which will be evaluated using the CAS-POL.

  15. Murine mammary tumor virus pol-related sequences in human DNA: characterization and sequence comparison with the complete murine mammary tumor virus pol gene

    International Nuclear Information System (INIS)

    Deen, K.C.; Sweet, R.W.

    1986-01-01

    Sequences in the human genome with homology to the murine mammary tumor virus (MMTV) pol gene were isolated from a human phage library. Ten clones with extensive pol homology were shown to define five separate loci. These loci share common sequences immediately adjacent to the pol-like segments and, in addition, contain a related repeat element which bounds this region. This organization is suggestive of a proviral structure. The authors estimate that the human genome contains 30 to 40 copies of these pol-related sequences. The pol region of one of the cloned segments (HM16) and the complete MMTV pol gene were sequenced and compared. The nucleotide homology between these pol sequences is 52% and is concentrated in the terminal regions. The MMTV pol gene contains a single long open reading frame encoding 899 amino acids and is demarcated from the partially overlapping putative gag gene by termination codons and a shift in translational reading frame. The pol sequence of HM16 is multiply terminated but does contain open reading frames which encode 370, 105, and 112 amino acids residues in separate reading frames. The authors deduced a composite pol protein sequence for HM16 by aligning it to the MMTV pol gene and then compared these sequences with other retroviral pol protein sequences. Conserved sequences occur in both the amino and carboxyl regions which lie within the polymerase and endonuclease domains of pol, respectively

  18. Prevalence of occupational disease

    Energy Technology Data Exchange (ETDEWEB)

    Newhouse, M.L.

    1976-12-01

    When discussing the prevalence of occupational disease, both the prescribed diseases and the diseases where occupation has an important etiological component should be considered. Available statistics indicate that there has been a substantial improvement in the control of important prescribed diseases such as lead poisoning and pneumoconiosis. In the United Kingdom in 1900 there were 1000 cases of lead poisoning with 38 fatalities. This number decreased to 49 cases in 1956 when the number again increased due to a change from clinical diagnosis to diagnosis on biochemical evidence. The number of cases of coal workers' pneumoconiosis has declined since the 1950s but the number of coal miners has also been reduced by more than /sup 1///sub 3/. Industrial dermatitis is still a considerable problem. Vibration induced white fingers was mentioned as a disease with a very large occupational component but which for a variety of reasons is not prescribed for industrial injury benefit. Illnesses due to injuries to the back, to sciatica, disc disease or lumbago cause a very large amount of sickness and are often associated with heavy manual labor particularly if an awkward posture has to be adopted for the job. The average absence after a back injury in the London Docks was 61 days. Chronic bronchitis is the biggest single cause of sickness absence. Many studies have shown that the etiology is multifactorial but that hard physical work and a dusty environment in the work place are important adverse factors. Improved control of the working environment and methods of work may influence the development of chronic disease in the older worker.

    Nucleoli are formed on the basis of ribosomal DNA (rDNA) clusters called Nucleolus Organizer Regions (NORs). Each NOR contains multiple genes coding for RNAs of the ribosomal particles. The prominent components of the nucleolar ultrastructure, fibrillar centers (FC) and dense fibrillar components (DFC), together compose FC/DFC units. These units are centers of rDNA transcription by RNA polymerase I (pol I), as well as the early processing events, in which an essential role belongs to fibrillarin. Each FC/DFC unit probably corresponds to a single transcriptionally active gene. In this work, we transfected human-derived cells with GFP-RPA43 (subunit of pol I) and RFP-fibrillarin. Following changes of the fluorescent signals in individual FC/DFC units, we found two kinds of kinetics: 1) the rapid fluctuations with periods of 2-3 min, when the pol I and fibrillarin signals oscillated in anti-phase manner, and the intensities of pol I in the neighboring FC/DFC units did not correlate. 2) fluctuations with periods of 10 to 60 min, in which pol I and fibrillarin signals measured in the same unit did not correlate, but pol I signals in the units belonging to different nucleoli were synchronized. Our data indicate that a complex pulsing activity of transcription as well as early processing is common for ribosomal genes.

    Full Text Available El artículo busca resaltar la relevancia de la vida política de Hilferding en el actual contexto de la crisis financiera global y la probablemente alta radicalización de las posiciones políticas de los países dominantes como resultado de aquella. Como se argumenta, había un alto grado de coherencia entre el pensamiento económico de Hilferding y su actuación política. Justamente por el hecho de que el proyecto socialista alemán durante la Republica Weimar no logró sus objetivos, el pensamiento político y económico de su líder intelectual es altamente relevante en el escenario global actual, donde la crisis económica y descomposición social y política que la acompañen reclaman a los principales políticos del mundo un entendimiento económico más amplio y profundo para que las tragedias de Europa central de los años treinta y cuarenta del siglo XX no se reproduzcan.

  6. Mitochondrial DNA replication: a PrimPol perspective

    Science.gov (United States)

    Bailey, Laura J.

    2017-01-01

    PrimPol, (primase–polymerase), the most recently identified eukaryotic polymerase, has roles in both nuclear and mitochondrial DNA maintenance. PrimPol is capable of acting as a DNA polymerase, with the ability to extend primers and also bypass a variety of oxidative and photolesions. In addition, PrimPol also functions as a primase, catalysing the preferential formation of DNA primers in a zinc finger-dependent manner. Although PrimPol's catalytic activities have been uncovered in vitro, we still know little about how and why it is targeted to the mitochondrion and what its key roles are in the maintenance of this multicopy DNA molecule. Unlike nuclear DNA, the mammalian mitochondrial genome is circular and the organelle has many unique proteins essential for its maintenance, presenting a differing environment within which PrimPol must function. Here, we discuss what is currently known about the mechanisms of DNA replication in the mitochondrion, the proteins that carry out these processes and how PrimPol is likely to be involved in assisting this vital cellular process.

    Contact dermatitis--irritant contact dermatitis, allergic contact dermatitis and protein contact dermatitis--are the most common occupational skin diseases, most often localized to the hands. Contact urticaria is rarer The main occupational irritants are wet work, detergents and disinfectants, cutting oils, and solvents. The main occupational allergens are rubber additives, metals (chromium, nickel, cobalt), plastics (epoxy resins, acrylic), biocides and plants. Diagnosis is based on clinical examination, medical history and allergy testing. For a number of irritating or sensitizing agents, irritant or allergic dermatitis can be notified as occupational diseases. The two main prevention measures are reducing skin contact with irritants and complete avoidance of skin contact with offending allergens.

    1996-02-01

    In a case of a fatal occupational accident (construction worker, fall from roof, urine test positive for cocaine and THC, e.g. cannabis) the question arised to what extent those drug-related occupational accidents occur. In the literature only few cases, mainly dealing with cannabis influence, have been reported, however, a higher number is suspected. Cocaine and other stimulating drugs (amphetamine) are more often used to increase physical fitness. By direct or indirect interference with vigilance these compounds may provoke accidents. Due to the lack of a legal basis proving of the influence of drugs at the working place is still very limited, although highly sensitive chemical-toxicological assay procedures are available to detect even the chronic abuse (in hair). In the general conditions of accident insurances a compensation is excluded when alcohol is involved, but drugs are not mentioned. It is indeed difficult to establish a concentration limit for drugs like that existing for alcohol (1.1%). In each case the assay of the drug involved and exact knowledge of its specific effects is in an essential prerequisite to prove the causal relationship.

  13. The effect of occupational meaningfulness on occupational commitment

    2014-11-01

    Full Text Available Existing research lacks a scholarly consensus on how to define and validly measure ‘meaningful work’ (e.g., Rosso, Dekas & Wrzesniewski, 2010. The following correlational study highlights the value of investigating meaningfulness in the context of occupational commitment. The study hypothesizes that occupational commitment is positively correlated with occupational meaningfulness, where meaningfulness is defined as the extent to which people’s occupations contribute to personal meaning in life. One-hundred and fifty-six full-time office based UK workers completed an online questionnaire including 18 questions measuring levels of occupational commitment (Meyer, Allen & Smith, 1993, in addition to six novel items measuring occupational meaningfulness. The results supported the hypothesis and also showed that the affective sub-type of occupational commitment had the highest correlation with occupational meaningfulness. Such results exhibit the importance of finding meaning at work, as well as the relevance of this to one’s level of commitment to his or her job. This paper argues that individuals should consider OM before choosing to take a specific role, whereas organizations ought to consider the OM of their potential candidates before recruiting them into a role. Possible directions for future research directions are also discussed.

    1993-06-01

    The adaptive functions of occupation during the phylogenetic history of the human species and the ontogenetic development of individual primates re examined through a review of relevant research of wild and captive nonhuman primates. This review suggests that the effectiveness of occupation as a therapeutic medium throughout life span development is fundamentally tied to humankind's phylogenetic history. It is accordingly argued that there is considerable justification to maintain occupational therapy's historical commitment to therapeutic occupation as the profession's primary treatment modality. To support this commitment, questions to guide practice and research are identified that emanate from the primate literature and that are highly germane to the therapeutic process in occupational therapy. These questions address: (a) the relationship between the press of the various environments in which occupational therapists practice and subsequent opportunities availed to patients for engagement in occupation; (b) the relationship between the extent to which patients are or are not empowered to exert real control over their use of time and their eventual development of disabling conditions; and (c) the therapeutic efficacy of occupation as compared with other treatment approaches that are not comparably holistic.

    The conserved co-activator complex Mediator enables regulated transcription initiation by RNA polymerase (Pol) II. Here we reconstitute an active 15-subunit core Mediator (cMed) comprising all essential Mediator subunits from Saccharomyces cerevisiae. The cryo-electron microscopic structure of cMed bound to a core initiation complex was determined at 9.7 Å resolution. cMed binds Pol II around the Rpb4-Rpb7 stalk near the carboxy-terminal domain (CTD). The Mediator head module binds the Pol II dock and the TFIIB ribbon and stabilizes the initiation complex. The Mediator middle module extends to the Pol II foot with a 'plank' that may influence polymerase conformation. The Mediator subunit Med14 forms a 'beam' between the head and middle modules and connects to the tail module that is predicted to bind transcription activators located on upstream DNA. The Mediator 'arm' and 'hook' domains contribute to a 'cradle' that may position the CTD and TFIIH kinase to stimulate Pol II phosphorylation.

    The incidence of epithelial skin neoplasms, such as squamous cell carcinoma and basal cell carcinoma is significantly increasing worldwide. Leisure time solar UV exposure is causative in the overwhelming majority of cases in the general population; however, occupational exposure is responsible for a certain percentage of cases. Employees with a relevant exposure to polycyclic aromatic hydrocarbons in soot, raw paraffin, coal tar, anthracene, pitch or similar substances, to sunlight in outdoor occupations as well as to arsenic and ionizing radiation have a significantly increased risk to develop occupational skin cancer compared to the general population. In the official occupational disease list in the appendix of the German by-law on occupational diseases, the following occupational diseases concerning skin cancer are listed: BK 5102 "skin cancer and carcinoma in situ caused by soot, raw paraffin, coal tar, anthracene, pitch or similar substances" (e.g. various solid paraffins, asphalt and mazut as well as mineral oils, grease, cylinder and drilling oils), BK 5103 "squamous cell carcinoma or multiple actinic keratosis caused by natural UV radiation", BK 1108 "diseases caused by arsenic and its compounds" and BK 2402 "diseases caused by ionizing radiation". For further occupational exposure to carcinogenic substances and potential occupationally acquired skin tumors, no official lists are currently available. These cancers might be considered under a special opt out paragraph in the German Social Law (§ 9 para 2 SGB VII). Tumors in scars after occupational skin trauma or occupational burns are compensated as consequences of work accidents. The current official list of occupational skin cancers and new developments for expert opinions are described in this article.

    Full Text Available RESUMEN: Este trabajo analiza el tejido político de la aristocracia romana en los años centrales del siglo II a.C, momento en el que los condicionantes socio-económicos derivados de la expansión mediterránea generan, a un tiempo, un aumento de las reivindicaciones de la plebe, y una importante acentuación de las rivalidades internas en el seno de la aristocracia. Con estas premisas, abordamos el estudio de los grupos de solidaridad política constituidos en torno a determinados individuos y familias. La significación de la figura de Escipión Emiliano no debe ocultar el papel de Mételo Macedónico, de los Calpurnios Pisones y, especialmente, de los Claudio-Fulvios, quienes ensayarán, de forma paralela a Emiliano, una nueva vía de protagonismo basada en la política social. ABSTRACT: This paper deals with the political organization of the Roman aristocracy during the central years of the Ilnd. Century b.C. The Roman conquest of the Mediterranean World, achieved by means of a considerable military effort, was responsible of the development in Italy of new social and economical factors. The growing popular claims and the acentuation of aristocratical competition are the main features of this trend. A prosopographical research makes it clear that some relevant political groups have been traditionaly hidden because of an excesive focus on Scipio Aemilianus. Thus, Metellus Macedonicus, the Calpurnii Pisones and, above all, the Claudii-Fulvii played a decisive paper in the context of political struggle, and some of their members even shared with Scipio an interest in pro-popular politics.

  1. A compromised yeast RNA polymerase II enhances UV sensitivity in the absence of global genome nucleotide excision repair.

    Wong, J M; Ingles, C J

    2001-02-01

    Nucleotide excision repair is the major pathway responsible for removing UV-induced DNA damage, and is therefore essential for cell survival following exposure to UV radiation. In this report, we have assessed the contributions of some components of the RNA polymerase II (Pol II) transcription machinery to UV resistance in Saccharomyces cerevisiae. Deletion of the gene encoding the Pol II elongation factor TFIIS (SII) resulted in enhanced UV sensitivity, but only in the absence of global genome repair dependent on the RAD7 and RAD16 genes, a result seen previously with deletions of RAD26 and RAD28, yeast homologs of the human Cockayne syndrome genes CSB and CSA, respectively. A RAD7/16-dependent reduction in survival after UV irradiation was also seen in the presence of mutations in RNA Pol II that confer a defect in its response to SII, as well as with other mutations which reside in regions of the largest subunit of Pol II not involved in SII interactions. Indeed, an increase in UV sensitivity was achieved by simply decreasing the steadystate level of RNA Pol II. Truncation of the C-terminal domain and other RNA Pol II mutations conferred sensitivity to the ribonucleotide reductase inhibitor hydroxyurea and induction of RNR1 and RNR2 mRNAs after UV irradiation was attenuated in these mutant cells. That UV sensitivity can be a consequence of mutations in the RNA Pol II machinery in yeast cells suggests that alterations in transcriptional programs could underlie some of the pathophysiological defects seen in the human disease Cockayne syndrome.

    Full Text Available It is a simplification of Raymond Aron´s thought to consider him as a mere neo-liberal political thinker. The French sociologist, a well-known political realist, took part in the famous controversy about Machiavellianism that was Aron´s intellectual watershed from the Forties. Starting from that controversy the aim of the present paper is to inquire into his contribution to the so-called “moderate Machiavellianism”, whose Arcanum is that it is not always possible to choose the optimal means to face the right political action. Machiavellianism is not a merely scientific or epistemological question, but something that deeply determines all political actions.

    La presentación de Raymond Aron como un escritor político neoliberal constituye una simplificación de su pensamiento. El sociólogo francés, que pertenece a la tradición del realismo político, tuvo una destacada intervención en la famosa polémica sobre el maquiavelismo que marcó un punto de inflexión en su pensamiento. Este artículo examina su contribución a esa inagotable polémica intelectual desde los años 40 y constata, finalmente, su encuadramiento en el denominado “maquiavelismo moderado”, cuyo arcano político es que, en política, no siempre se pueden elegir los medios de la acción. El maquiavelismo no es, en este sentido, un asunto científico o epistemológico, sino que determina profundamente toda acción política.

O objetivo do texto é triplo: chamar a atenção para a fertilidade das ideias de um autor ainda pouco lido no Brasil (i, assinalar as notáveis consequências corrosivas da abordagem rortyana para pressupostos e pretensões fundantes de importantes vertentes da teoria política (ii, e, numa ótica mais positiva, apontar o potencial inspirador dos escritos desse autor para a reflexão sobre novos modos de justificação da democracia (iii. Salientam-se também, nesse último caso, os limites impostos a esse tipo de empreitada político-intelectual. A abordagem empregada consiste em demarcar os contornos gerais do projeto filosófico do autor, seguindo-se uma apresentação dos tópicos mais propriamente políticos da obra de Rorty. Mais especificamente, o artigo explora a proposta rortyana de substituição da noção de verdade pela de justificação, assinalando-se suas consequências para pretensões de verdade, objetividade e universalismo, presentes em diversas linhas da teoria política. Nesse veio, o artigo discute as eventuais implicações relativistas das teses rortyanas, chegando-se, por essa rota, às ideias de contingência, imaginação e persuasão, núcleos conceituais vitais à reflexão em tela. Um breve contraste com posições de autores como Habermas e Rawls, caros ao próprio Rorty, é esboçado no propósito de tornar mais clara a especificidade da abordagem rortyana da política. Transitando, do modo assinalado, por esses tópicos, o texto resulta em um panorama sintético da perspectiva rortyana acerca do que vem a ser, contemporaneamente, uma "política democrática", liberta de "universalismos" e "objetividades", na qual ganham estatuto decisivo questões de justificação, tolerância e coexist

    Full Text Available Making final decisions on the occupational etiology of musculoskeletal diseases is often difficult and problematic at every stage of the diagnostic procedure. Taking into account the need to facilitate decision-making about the causal relationship between the diagnosed disease entity and the working conditions guidelines for the recognition of work-related musculoskeletal diseases have been developed. This paper presents the guidelines for the diagnosis of occupational etiology of humeral epicondylitis, one of the most common occupational disease of the musculoskeletal system in Poland. The developed guidelines have been based on the literature data concerning occupational risk factors of humeral epicondylitis, workload classification, including repetitive movements, awkward postures, and force. Some criteria applied in ergonomic evaluation methods were also included. The presented diagnostic guidelines define approximate benchmarks for stating (after excluding non-occupational etiology that the identified humeral epicondylitis, is related to the way of working. Crucial work factors that should be analyzed include an operating time of movements overloading tendons connecting to the epicondyle, repetition and force used to perform occupational activities. The developed guidelines are aimed to facilitate occupational physicians diagnostic and certification procedures in case of humeral epicondylitis and determination whether there is a likelihood of its occupational etiology.

    1988-01-01

    In this paper, the author shows that a real and concrete elevation of cancer cases has to be expected in all groups of occupationally irradiated perons. The risk figure one should use for mortality is 0.1% per rem of whole body dose. The mean dose registered for these persons lies well below the maximum permissible dose. In Germany there are about 0.2 rem per year in medical people and below 0.5 rem per year in the nuclear industry. But there are risk groups working in situations with typical higher exposure. In medicine, these are for example nurses working with radium implants in radiotherapy units, technicians doing cardiac catheterization and cholangiogrammes, nurses and physicians holding very young patient during X-ray investigations. In the nuclear industry there are also high level and low level working areas. Highest doses are generally delivered to personnel who are engaged from outside for revision and cleaning procedures

  16. Occupational Animal Allergy.

    Stave, Gregg M

    2018-02-16

    This review explores animal allergen exposure in research laboratories and other work settings, focusing on causes and prevention. (1) Consistent with the hygiene hypothesis, there is new evidence that early childhood exposure to pets produces changes in the gut microbiome that likely lead to a lower risk of allergy. (2) Anaphylaxis from laboratory animal bites occurs more frequently than suggested by prior literature. (3) Animal allergens represent an occupational hazard in a wide variety of work settings ranging from fields that work with animals to public settings like schools and public transportation where allergens are brought into or are present in the workplace. Exposure to animal allergens can result in allergy, asthma, and anaphylaxis. Animal allergy has been most studied in the research laboratory setting, where exposure reduction can prevent the development of allergy. Similar prevention approaches need to be considered for other animal work environments and in all settings where animal allergens are present.

    OBJECTIVE: Previous studies have indicated that shift work, long working hours, and prevalent workplace exposures such as lifting, standing, and physical workload increase the risk of miscarriage, but the evidence is conflicting. We conducted a systematic review of original research reports......% confidence interval (95% CI) 1.27-1.78, N=5), while working in 3-shift schedules, working for 40-52 hours weekly, lifting >100 kg/day, standing >6-8 hours/day and physical workload were associated with small risk increments, with the pooled RR ranging from 1.12 (3-shift schedule, N=7) to 1.36 (working hours......, N=10). RR for working hours and standing became smaller when analyses were restricted to higher quality studies. CONCLUSIONS: These largely reassuring findings do not provide a strong case for mandatory restrictions in relation to shift work, long working hours, occupational lifting, standing...

    1992-01-01

    Ergonomics is often defined simply as the study of work. Related or synonymous terms include human factors, human engineering, engineering psychology, and others. Occupational ergonomics is a term that has been proposed to describe the study of the working environment, including the physical consequences resulting from having an improperly designed workplace. The routine space working environment presents some problems not found in the typical Earthbound workplace. These include radiation, intravehicular contamination/pollution, temperature extremes, impact with other objects, limited psychosocial relationships, sensory deprivation, and reduced gravity. These are important workplace considerations, and may affect astronauts either directly at work or at some point during their life as a result of their work under these conditions. Some of the major issues associated with each of these hazards are presented.

    Full Text Available Institutions of higher education that respond to the economic base in their region will remain competitive and be better positioned to obtain public funds and donor support. In addition to mandated program viability standards based on measures such as graduation rate, individual institutions and state coordinating boards can use ten-year occupational trend data to assess future program viability. We used an occupational demand model to determine whether academic programs can meet projected statewide needs for high demand and high growth occupations. For example, computer engineering, the highest growth rate occupation in Alabama, is projected to have 365 annual average job openings, with 93.6% total growth over ten years. But only 46 computer engineering majors graduate annually from all Alabama institutions of higher education. We recommend using an occupational demand model as a planning tool, decision-making tool, and catalyst for collaborative initiatives.

    Occupational therapy is a global profession represented by the World Federation of Occupational Therapists (WFOT). International research priorities are needed for strategic guidance on global occupational therapy practice. The objective of this study was to develop international research priorities to reflect global occupational therapy practice. A Delphi study using three rounds of electronic surveys, distributed to WFOT member organizations and WFOT accredited universities, was conducted. Data were analyzed after each round, and priorities were presented for rating and ranking in order of importance. Forty-six (53%) out of 87 WFOT member countries participated in the Delphi process. Eight research priorities were confirmed by the final electronic survey round. Differences were observed in rankings given by member organizations and university respondents. Despite attrition at Round 3, the final research priorities will help to focus research efforts in occupational therapy globally. Follow-up research is needed to determine how the research priorities are being adopted internationally.

    It is estimated that about 4% of cancer mortality is attributed to occupational risk factors. Due to long latency periods it is often difficult to establish causal relationships. Thoracal cancer accounts for about 88% of all compensated occupational cancers in Germany. Most important exposures and diseases are asbestos-related lung cancer, asbestos-related malignant mesothelioma and radiation induced lung cancer (by Radon and its decay products). Lung cancer caused by nickel compounds, hexavalent chromium, arsenic and its compounds, coke oven gases and polycyclic aromatic hydrocarbons are rare. Silica-dust induced lung cancer can be compensated as occupational disease if a silicosis is present. In Germany every physician is obliged to notify a suspected occupational cancer as well as other occupational diseases. (orig.) [de

    Airborne allergens are the major cause of allergic rhinitis and asthma. Daily exposure comes from indoor sources, chiefly at home but occasionally at schools or offices. Seasonal exposure to outdoor allergens, pollens, and molds is another important source. Exposure to unusual substances at work causes occupational asthma, accounting for about 5% of asthma in adults. Indoor and outdoor air pollutants trigger airway inflammation and increase the severity of asthma. Diesel exhaust particles increase the production of IgE antibodies. Identification and reduction of exposure to allergens is a very important part of the management of respiratory allergic diseases. The first section of this chapter discusses domestic allergens, arthropods (mites and cockroaches), molds, and mammals (pets and mice). Indoor humidity and water damage are important factors in the production of mite and mold allergens, and discarded human food items are important sources of proliferation of cockroaches and mice. Means of identifying and reducing exposure are presented. The second section discusses outdoor allergens: pollens and molds. The particular plants or molds and the amount of exposure to these allergens is determined by the local climate, and local pollen and mold counts are available to determine the time and amount of exposure. Climate change is already having an important effect on the distribution and amount of outdoor allergens. The third section discusses indoor and outdoor air pollution and methods that individuals can take to reduce indoor pollution in addition to eliminating cigarette smoking. The fourth section discusses the diagnosis and management of occupational asthma. Copyright 2010 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc. All rights reserved.

    Full Text Available Abstract Background Foamy viruses (FVs unlike orthoretroviruses express Pol as a separate precursor protein and not as a Gag-Pol fusion protein. A unique packaging strategy, involving recognition of briding viral RNA by both Pol precursor and Gag as well as potential Gag-Pol protein interactions, ensures Pol particle encapsidation. Results Several Prototype FV (PFV Gag-Pol fusion protein constructs were generated to examine whether PFV replication is compatible with an orthoretroviral-like Pol expression. During their analysis, non-particle-associated secreted Pol precursor protein was discovered in extracellular wild type PFV particle preparations of different origin, copurifying in simple virion enrichment protocols. Different analysis methods suggest that extracellular wild type PFV particles contain predominantly mature p85PR-RT and p40IN Pol subunits. Characterization of various PFV Gag-Pol fusion constructs revealed that PFV Pol expression in an orthoretroviral manner is compatible with PFV replication as long as a proteolytic processing between Gag and Pol proteins is possible. PFV Gag-Pol translation by a HIV-1 like ribosomal frameshift signal resulted in production of replication-competent virions, although cell- and particle-associated Pol levels were reduced in comparison to wild type. In-frame fusion of PFV Gag and Pol ORFs led to increased cellular Pol levels, but particle incorporation was only marginally elevated. Unlike that reported for similar orthoretroviral constructs, a full-length in-frame PFV Gag-Pol fusion construct showed wildtype-like particle release and infectivity characteristics. In contrast, in-frame PFV Gag-Pol fusion with C-terminal Gag ORF truncations or non-removable Gag peptide addition to Pol displayed wildtype particle release, but reduced particle infectivity. PFV Gag-Pol precursor fusion proteins with inactivated protease were highly deficient in regular particle release, although coexpression of p71Gag

    The Schneeberg lung disease is the lung cancer, conditioned by radiation which is caused by the influence of radon and of its subsequent products. It has gained a great importance after World War II as a consequence of the intensified mining of uranium ore. From the history of the disease, lasting some centuries, the period of the twenties and thirties of this century is represented in which on one side the conception of the causal importance of radon has made its way little by little, and on the other side the disease was acknowledged as occupational disease within the first decree of occupational diseases in the former German Reich. Evaluating materials from Saxon archives it is described how the legislative preparations to the acknowledgement of the Schneeberg lung disease as occupational disease and the simultaneous research to the elucidation of nature and cause of the disease have penetrated and influenced each other.

Recusando a perspectiva que dissocia a Filosofia Política da dimensão empiricamente orientada da disciplina, os argumentos apresentados destacam o papel de fertilização de formas de vida cumprido pela primeira. A agenda dos pesquisadores devotados à boa faina da investigação empírica foi, e segue sendo, em grande medida definida e configurada por exercícios prévios de invenção social e política e por decisões de ordem ontológica, epistemológica e retórica. Neste sentido, a distinção entre ciência e filosofia é, além de obscurantista e marcada por enorme otimismo epistemológico, sintoma de um desconhecimento forte com relação à história do conhecimento político.

    Full Text Available El problema político de la sociedad civil se fundamenta en su doble forma de manifestarse: por un lado, en ella se revela el carácter externo u objetivo del Estado y, por otro, produce una escisión al interior del mismo Estado. Tal problema que aparece como contradictorio (el ser exterior e interior a la vez es presentado en el pensamiento político de Hegel, en vistas a superar las dicotomías que en la teoría política moderna aparecían como insalvables. Esta superación Hegel la realiza mediante una interiorización de aquellos elementos que anteriormente habían sido marginados de la política, como son lo natural y el dominio privado, los que emergerían en la sociedad civil. En este artículo se exponen estos elementos en vistas a mostrar cómo es en este movimiento de interiorización y exteriorización de ellos donde se posibilita el acontecer de lo político.

    Multiple myeloma (MM) is an incurable plasma cell malignancy with a poorly understood etiology. The purpose of our research was to examine the relationships between lifetime occupations and MM in a relatively large case-control study. MM cases (n = 180) were identified through cancer registries in the Seattle-Puget Sound area and Detroit. Population-based controls (n = 481) were identified using random digit dialing and Medicare and Medicaid Services files. In-person interviews were conducted to ascertain occupational histories. Standard occupational classification (SOC) and standard industrial classification (SIC) codes were assigned to each job held by each participant. Unconditional logistic regression was used to generate odds ratios (ORs) and 95% confidence intervals (CIs) for associations between MM and having ever worked in each occupation/industry and according to duration of employment in an occupation/industry. The risk of MM was associated with several manufacturing occupations and industries, including machine operators and tenders, not elsewhere classified (SOC 76) (OR = 1.8, CI = 1.0-3.3); textile, apparel, and furnishing machine operators and tenders (SOC 765) (OR = 6.0, CI = 1.7-21); and machinery manufacturing, except electrical (SIC 35) (OR = 3.3, CI = 1.7-6.7). Several service occupations and industries, such as food and beverage preparation (SOC 521) (OR = 2.0, CI = 1.1-3.8), were also associated with MM. One occupation that has been associated with MM in several previous studies, painters, paperhangers, and plasterers (SOC 644) was associated with a non-significantly elevated risk (OR = 3.6, CI = 0.7-19). We found associations between the risk of MM and employment in several manufacturing and service-related occupations and industries. Copyright 2010 Wiley-Liss, Inc.

El primero —el de Gran Bretaaña, Bélgica y Holanda— se caracterizó por su gradualismo, tras la renuncia por parte del bloque político secular a apropiarse del Estado y su aceptación de la idea de que éste debía limitarse a proteger la libertad inherente al individuo. En cambio, el modelo de laicismo estatista —vigente en Francia, Italia y, en su versión más extrema, en la España de la II República—, partía de la idea de que el Estado era intérprete absoluto de un poder que no puede fragmentarse sin dejar de ser democrático, y se tradujo en el intento de contrarrestar la presencia católica mediante la imposición de políticas laicas, especialmente en el ámbito de la educación.

Dessa maneira, verifica-se (i que os brasileiros são pouco ou nada interessados por política; (ii participam das eleições mas não das atividades tradicionais e novas formas de engajamento político; (iii apoiam e estão razoavelmente satisfeitos com a democracia. Em relação aos mais escolarizados, temos o predomínio de mulheres, um público mais jovem e com renda familiar sutilmente superior à dos menos escolarizados. Aqueles que possuem o ensino superior completo tendem a se comportar de forma distinta: são levemente mais informados e interessados por política; apesar dos baixos percentuais encontrados, são os que mais participam das atividades políticas em geral; são os que mais apoiam a democracia, porém os mais insatisfeitos com o seu funcionamento.

  20. Occupational lung diseases in Australia.

    Occupational exposures are an important determinant of respiratory health. International estimates note that about 15% of adult-onset asthma, 15% of chronic obstructive pulmonary disease and 10-30% of lung cancer may be attributable to hazardous occupational exposures. One-quarter of working asthmatics either have had their asthma caused by work or adversely affected by workplace conditions. Recently, cases of historical occupational lung diseases have been noted to occur with new exposures, such as cases of silicosis in workers fabricating kitchen benchtops from artificial stone products. Identification of an occupational cause of a lung disease can be difficult and requires maintaining a high index of suspicion. When an occupational lung disease is identified, this may facilitate a cure and help to protect coworkers. Currently, very little information is collected regarding actual cases of occupational lung diseases in Australia. Most assumptions about many occupational lung diseases are based on extrapolation from overseas data. This lack of information is a major impediment to development of targeted interventions and timely identification of new hazardous exposures. All employers, governments and health care providers in Australia have a responsibility to ensure that the highest possible standards are in place to protect workers' respiratory health.

    Simulated learning experiences are increasingly being used in health-care education to enhance student engagement and provide experiences that reflect clinical practice; however, simulation has not been widely investigated in occupational therapy curricula. The aim of this paper was to: (i) describe the existing research about the use and evaluation of simulation over the last three decades in occupational therapy curricula and (ii) consider how simulation has been used to develop competence in students. A literature review was undertaken with searches of MEDLINE, CINAHL and ERIC to locate articles that described or evaluated the use of simulation in occupational therapy curricula. Fifty-seven papers were identified. Occupational therapy educators have used the full scope of simulation modalities, including written case studies (22), standardised patients (13), video case studies (15), computer-based and virtual reality cases (7), role-play (8) and mannequins and part-task trainers (4). Ten studies used combinations of these modalities and two papers compared modalities. Most papers described the use of simulation for foundational courses, as for preparation for fieldwork, and to address competencies necessary for newly graduating therapists. The majority of studies were descriptive, used pre-post design, or were student's perceptions of the value of simulation. Simulation-based education has been used for a wide range of purposes in occupational therapy curricula and appears to be well received. Randomised controlled trials are needed to more accurately understand the effects of simulation not just for occupational therapy students but for longer term outcomes in clinical practice. © 2017 Occupational Therapy Australia.

    Prioritising control measures for occupationally related cancers should be evidence based. We estimated the current burden of cancer in Britain attributable to past occupational exposures for International Agency for Research on Cancer (IARC) group 1 (established) and 2A (probable) carcinogens. We calculated attributable fractions and numbers for cancer mortality and incidence using risk estimates from the literature and national data sources to estimate proportions exposed. 5.3% (8019) cancer deaths were attributable to occupation in 2005 (men, 8.2% (6362); women, 2.3% (1657)). Attributable incidence estimates are 13 679 (4.0%) cancer registrations (men, 10 063 (5.7%); women, 3616 (2.2%)). Occupational attributable fractions are over 2% for mesothelioma, sinonasal, lung, nasopharynx, breast, non-melanoma skin cancer, bladder, oesophagus, soft tissue sarcoma, larynx and stomach cancers. Asbestos, shift work, mineral oils, solar radiation, silica, diesel engine exhaust, coal tars and pitches, occupation as a painter or welder, dioxins, environmental tobacco smoke, radon, tetrachloroethylene, arsenic and strong inorganic mists each contribute 100 or more registrations. Industries and occupations with high cancer registrations include construction, metal working, personal and household services, mining, land transport, printing/publishing, retail/hotels/restaurants, public administration/defence, farming and several manufacturing sectors. 56% of cancer registrations in men are attributable to work in the construction industry (mainly mesotheliomas, lung, stomach, bladder and non-melanoma skin cancers) and 54% of cancer registrations in women are attributable to shift work (breast cancer). This project is the first to quantify in detail the burden of cancer and mortality due to occupation specifically for Britain. It highlights the impact of occupational exposures, together with the occupational circumstances and industrial areas where exposures to carcinogenic agents

    The American Occupational Therapy Association (AOTA) has challenged occupational therapy practitioners to advance the profession so that we may become more "powerful" and "widely recognized" by the year 2017 (AOTA, 2007a). To fully achieve this vision, this article argues that the profession should encourage occupational therapy entrepreneurship. As Herz, Bondoc, Richmond, Richman, and Kroll (2005, p.2) stated, "Entrepreneurship may provide us with the means to achieve the outcomes we need to succeed in the current health care environment." This article also argues the urgency of seizing the many opportunities that entrepreneurship offers and recommends specific actions to be taken by AOTA and by therapists.

    From pre-historic times miners represented the group which received, inadvertently, occupational exposure to natural radionuclides. At the end of the 19th century scientists researching the newly found radiation called ''radioactivity'' became exposed frequently to uranium, thorium and their decay chains, still hardly aware of the potential risks associated with their work. In the first half of the 20th century some employees in the radium industry received high doses in the course of their professional duties as chemists, maintenance workers, or radium dial painters; many of them lacked adequate information on radiation protection. After World War II the increased international demand for uranium in the military and civilian sector caused overexposures of several thousands of miners (volunteers, prisoners), mostly due to the inhalation of elevated levels of radon and its decay products. By comparison on an international scale a relatively small number of workers was exposed to increased levels of thorium and its decay products in the thorium and rare-earth extraction industry. Health effects due to these past exposures range from relatively weak associations to statistically significant excesses for a variety of symptoms, such as respiratory diseases or cancer of the bone, lung or pancreas. An assessment of today industrial exposure situations indicates a wide range of occupations exposed to partly significant levels of natural radionuclides. 36 refs., 7 tabs., 3 figs

    Full Text Available Hydatidosis is a common infestation caused by Echinococcus spp. Solitary hydatid cyst of the lung is not uncommon but coexistence of two or more pulmonary cysts are less common. These cysts may drain into the bronchial tree or very rarely into the pleural cavity which causes a poor outcome. Certain people such as slaughters, tanners, stockbreeders, shepherds, butchers, veterinarians and all whose job makes them to work closely with animals are at higher risk of the infection and developing echinococcosis. Herein, we present a 14-year-old shepherd who developed severe chest pain and hydropneumothorax following a minor trauma to his chest. He had two pulmonary hydatid cysts, one of which drained to the left pleural cavity and caused the symptoms. Another cyst was complicated during his hospital course. The patient was treated surgically, received albendazole and discharged home uneventfully. A high index of suspicion is of utmost importance for the correct diagnosis and treatment of hydatid disease in hyperendemic areas and in those whose occupation might put them at a higher risk of contraction of hydatid disease.

    There have been two High Court actions and seven inquests in the UK, with reference to the debate on occupational hazards of long term, low dose exposure. In July, 1987, two cases alleging that workers in the nuclear industry had contracted cancer due to their exposure to radiation at work had to be abandoned halfway through the trial after the judge had heard the medical evidence. A 57-year old man claimed that Hodgkin's disease had been caused by radiation while at work at Sellafield. However, medical opinion was that Hodgkin's disease had never been accepted as caused by radiation. In the second case a man who had died of stomach cancer at the age of 54 after working for UKAEA at Dounreay for 7 years, had received 190 mSv. The defendants' experts rated the likelihood of radiation as the cause at 3-6%; the plaintiffs' experts had suggested 30-50%. Seven inquest juries sitting in West Cumbria from 1983 to 1988 have brought in three verdicts of death caused by an industrial disease, three open verdicts, and one of natural causes. The men had all worked for BNFL at Sellafield for many years. (author)

    Recording of occupational doses received by radiation workers during their working life is a mandatory aspect of radiation protection. Maintaining of life-time dose data of these radiation workers is also necessary for (i) ensuring and reviewing radiation safety of workers, (ii) certification and other legal purposes, and (iii) for statistical analysis and epidemiological studies. Centralized dose records are being maintained by BARC since the inception of Directorate of Radiation Protection in late sixties. The dose records were computerized since 1975 and the systems were upgraded from time to time. The requirement of personnel data information was made a pre-requisite for allotment of personnel number to new persons for TLD Badge services since 1992

    Full Text Available Abstract Background Infection with HIV, which culminates in the establishment of a latent proviral reservoir, presents formidable challenges for ultimate cure. Building on the hypothesis that ex-vivo or even in-vivo abolition or disruption of HIV-gene/genome-action by target mutagenesis or excision can irreversibly abrogate HIV's innate fitness to replicate and survive, we previously identified the isoschizomeric bacteria restriction enzymes (REases AcsI and ApoI as potent cleavers of the HIV-pol gene (11 and 9 times in HIV-1 and 2, respectively. However, both enzymes, along with others found to cleave across the entire HIV-1 genome, slice (SX at palindromic sequences that are prevalent within the human genome and thereby pose the risk of host genome toxicity. A long-term goal in the field of R-M enzymatic therapeutics has thus been to generate synthetic restriction endonucleases with longer recognition sites limited in specificity to HIV. We aimed (i to assemble and construct zinc finger arrays and nucleases (ZFN with either proviral-HIV-pol gene or proviral-HIV-1 whole-genome specificity respectively, and (ii to advance a model for pre-clinically testing lentiviral vectors (LV that deliver and transduce either ZFN genotype. Methods and Results First, we computationally generated the consensus sequences of (a 114 dsDNA-binding zinc finger (Zif arrays (ZFAs or ZifHIV-pol and (b two zinc-finger nucleases (ZFNs which, unlike the AcsI and ApoI homeodomains, possess specificity to >18 base-pair sequences uniquely present within the HIV-pol gene (ZifHIV-polFN.

Lo que conocemos de la biografía de Cervantes, sus inquietudes vitales, los argumentos de sus obras y los misterios que rodearon su mecenazgo y participación en la «república de las letras» se relacionan no sólo con el contexto político de desencanto tras la grandeza imperial de Felipe II sino también con la relación con personajes concretos de la Corte de Felipe III y con algunos acontecimientos, como la expulsión de los moriscos, que marcaron tanto el reinado como la propia obra cervantina. Lo cierto es que no existen demasiadas fuentes a partir de las cuales puedan estudiarse estas conexiones, pero es indudable que el creador está unido a una época en la que debe sobrevivir y a la que debe gran parte de sus preocupaciones literarias. En este trabajo se esbozan algunas conexiones políticas de Cervantes, recuperando parte de la bibliografía de los llamados «cervantistas» decimonónicos.ABSTRACT: Miguel de Cervantes' life and work contain interesting data to study the Modern Age politics and courts connections between the writer and the power ful groups at that time.

    Sunlight causes lesions in DNA that if unrepaired and inaccurately replicated by DNA polymerases yield mutations that result in skin cancer in humans. Two enzymes involved in translesion synthesis (TLS) of UV-induced photolesions are DNA polymerase η (Polη) and polymerase ζ (Polζ), encoded by the RAD30A and REV3 genes, respectively. Previous studies have investigated the TLS roles of these polymerases in human and yeast cells irradiated with monochromatic, short wavelength UVC radiation (254 nm). However, less is known about cellular responses to solar radiation, which is of higher and mixed wavelengths (310–1100 nm) and produces a different spectrum of DNA lesions, including Dewar photoproducts and oxidative lesions. Here we report on the comparative cytotoxic and mutagenic effects of simulated sunlight (SSL) and UVC radiation on yeast wild-type, rad30Δ, rev3Δ and rev3Δ rad30Δ strains. The results with SSL support several previous interpretations on the roles of these two polymerases in TLS of photodimers and (6–4) photoproducts derived from studies with UVC. They further suggest that Polη participates in the non-mutagenic bypass of SSL-dependent cytosine-containing Dewar photoproducts and 8-oxoguanine, while Polζ is mainly responsible for the mutagenic bypass of all types of Dewar photoproducts. They also suggest that in the absence of Polζ, Polη contributes to UVC- and SSL-induced mutagenesis, possibly by the bypass of photodimers containing deaminated cytosine. PMID:12888515

    Full Text Available O modo de conduzir a formulação das políticas de desenvolvimento regional tem se constituído em ampla arena de embates acadêmicos e técnicos e levado a reflexões sobre os rumos das múltiplas políticas que acompanham esse processo de planejamento regional. Isso, em parte, decorre do processo de globalização e das políticas neoliberais que o acompanham, as quais possuem um forte apelo à competitividade. Essa estratégia de buscar espaços "privilegiados" se fez presente de uma forma intensa em alguns setores produtivos, que, ao usar o espaço como mercadoria, utilizam seu conjunto de atributos (naturais e artificiais para realizarem-se e reproduzirem-se como parte do sistema. Assim, a proposta de estudo pretende responder a questão: em que medida as políticas públicas setoriais têm dialogado com as políticas de planejamento e desenvolvimento regional no âmbito do governo federal? No caso das políticas de planejamento regional, o recorte espacial é visto como um instrumento que, ao ser aplicado, pode se mostrar capaz de viabilizar a integração de ações multissetorializadas, o que em certa dimensão apontaria para uma maior eficiência do Estado na busca por restabelecer o equilíbrio esgarçado, tornando mais eficiente o planejamento.

    The U.S. Department of Energy (DOE) Office of Analysis within the Office of Health, Safety and Security (HSS) publishes the annual DOE Occupational Radiation Exposure Report to provide an overview of the status of radiation protection practices at DOE.* The DOE 2010 Occupational Radiation Exposure Report provides an evaluation of DOE-wide performance regarding compliance with DOE Part 835 dose limits and as low as reasonably achievable (ALARA) process requirements. In addition, the report provides data to DOE organizations responsible for developing policies for protection of individuals from the effects of radiation. The report provides a summary and an analysis of occupational radiation exposure information from the monitoring of individuals involved in DOE activities. The occupational radiation exposure information is analyzed in terms of aggregate data, dose to individuals, and dose by site over the past 5 years.

This Editorial argues that family physicians are indeed in a position where they can make a major positive difference for their working patients and for the enterprises where they work. Without specialist knowledge in occupational medicine, the family physician......’s empiric knowledge in combination with a narrative approach to the patient permits the contribution from family medicine not only with regard to diagnosis and treatment, but also relating to actions targeted to optimize the patient’s future accommodation at work as well as to protect other similarly......In Denmark, the practice of occupational medicine tends to be carried out by specialists in occupational medicine and less so by family physicians. The provision of health service to workers is therefore limited. This constraint may also apply in other developed countries and even more in countries...

    2017-09-01

    Work in the visual arts, performing arts, and writing can involve exposures to occupational hazards, including hazardous materials, equipment, and conditions, but few art workplaces have strong occupational health resources. Literature searches were conducted for articles that illustrate these concerns. Medical databases were searched for art-related health articles. Other sources were also reviewed, including, unindexed art-health publications, and popular press articles. Information was located that described some exposed populations, art-related hazards, and resulting disorders. Anecdotal reports were used when more complete data were not available. Health hazards in the arts are significant. Occupational health professionals are familiar with most of these concerns and understand their treatment and prevention. The occupational health approach can reduce the health hazards encountered by at-risk art workers. Additional research would benefit these efforts. Resources for further information are available.

  13. Spiritual Assessments in Occupational Therapy

    Directory of Open Access Journals (Sweden)

    Barbara Hemphill

    2015-07-01

    Full Text Available Spirituality is recognized as an important concept in the study and practice of medicine, including occupational therapy. This aligns with occupational therapy’s core value of treating people holistically—mind, body, and spirit. Currently, the Joint Commission for the Accreditation of Hospital Organizations ( JCAHO requires that a spiritual assessment be given to patients on admission. To conduct effective spiritual assessments, occupational therapists must distinguish between religion and spirituality. They also must be aware of their own spiritual beliefs and practices and how those might influence their clinical interactions. This article presents spiritual assessment tools that occupational therapists can use in clinical practice; they range from history taking, to questionnaires, to observation scales. Guidelines are presented for selecting among several spiritual assessments. A case study is presented in which a patient’s faith tradition is being challenged, which could affect the outcome of therapy. Finally, treatment and intervention planning and ethical considerations are discussed.

  16. Sleep as an Occupational Need.

    Science.gov (United States)

    Tester, Nicole J; Foss, Joanne Jackson

    In the same way the human body requires food, hydration, and oxygen, it also requires sleep. Even among healthy people, the amount and quality of sleep substantially influence health and quality of life because sleep helps regulate physiological functioning. Given the impact of sleep on participation, the American Occupational Therapy Association reclassified sleep from an activity of daily living to an occupational domain. Poor sleep is a frequent medical complaint, especially among populations with neurological impairment. Occupational therapy practitioners should consider routinely screening for factors affecting their clients' sleep. By addressing such factors, as well as related routines and habits, practitioners can enhance the effectiveness of rehabilitation, promote health and well-being, and increase engagement and life quality. Practitioners should acknowledge the importance of sleep in practice, and the study of sleep should be prioritized by researchers in the field to meet client needs and establish evidence for interventions.

  17. Occupational applications of ultraviolet radiation

    International Nuclear Information System (INIS)

    Eriksen, P.

    1987-01-01

    A large population of workers are exposed to ultraviolet radiation in various occupational environments which often necessitates protection. Since ultraviolet radiation may create other environmental problems an occupational hazard- and protection evaluation can be complicated. Threshold Limit Values adopted by the American Conference of Governmental Industrial Hygienists (ACGIH) on ultraviolet radiation are used in most countries as guidelines for risk assessment and control measures. This review addresses the levels of ultraviolet radiation met in occupational environments, its measurement and evaluation, and discusses different protection methods. Ultraviolet lasers are beginning to find their way into industrial processes but are still limited in number and they will not be covered here. Emphasis is on broad band incoherent radiation in high risk environments such as welding, and on the evaluation of protective eyewear, see-through curtains and plastics. Other occupational risks associated with the emission of ultraviolet radiation are discussed

  6. La escisión entre Ciencia Política y realidad política: el caso de la Seguridad Democrática

    Directory of Open Access Journals (Sweden)

    Carlos Andrés Ramírez González

    2014-12-01

    Full Text Available La política de seguridad democrática, adoptada por el Presidente Álvaro Uribe Vélez durante su periodo de gobierno, resultó en un viraje fundamental en los rumbos del país luego del fallido proceso de paz del gobierno Pastrana. En este sentido, el presente trabajo busca demostrar que la Ciencia Política abordó el fenómeno político en contravía con el curso de los hechos, de tal manera que mientras la política de Seguridad Democrática propugnaba por un aumento en la ofensiva militar, la visión desde la Ciencia Política se concentraba en la manera de llegar a unos diálogos de paz o una salida concertada al conflicto. Esto, por tanto, se puede traducir en un rechazo al punto de vista preponderante y a una postura alternativa en el estudio de la realidad política nacional. Para demostrar lo anterior, se realiza una revisión documental aplicada a artículos académicos en cuatro revistas de Ciencia Política del país: Análisis Político, Colombia Internacional, Papel Político y Estudios Políticos durante el periodo de publicación de 2002 a 2012.

    1989-01-01

    Findings from a survey of 56,067 women in Montreal on maternal occupation and pregnancy outcome have been reported. Paternal occupation recorded in the same survey was analysed for spontaneous abortion in 24 occupational groups retaining the six main sectors of maternal occupation and allowing, by means of logistic regression, for seven potentially confounding variables. In only one of the 24 fathers' occupational groups was there a statistically significant excess of spontaneous abortions-mechanics, repairers, and certain assemblers (O/E = 1.10, 90% CI = 1.02-1.20); subdivision of this group suggested that this excess was mainly attributable to the large group of motor vehicle mechanics (O/E = 1.17). No significant excess of known chromosomally determined defects was found in any of the 24 occupational groups. An association of developmental defects was found with food and beverage processing (18 defects observed compared with 8.02 expected; p < 0.05); however, there was no specificity in type of food, beverage, or congenital defect, and no obvious explanatory mechanism.

  8. Occupational risk of building construction

    International Nuclear Information System (INIS)

    Aneziris, O.N.; Topali, E.; Papazoglou, I.A.

    2012-01-01

    This paper presents the quantification of occupational risk of a building construction project. Risk assessment is based on the Occupational Risk Model (ORCA) developed under the Workgroup Occupational Risk Model project (WORM), in the Netherlands, for quantifying occupational risk. This model assesses occupational risk of a worker, by taking into account his various tasks, activities and their hazards. Risk is evaluated for three types of consequences: recoverable injury, permanent injury and death. The occupational risk model is based on a set of 63 bowties, which assess risk owing to different hazards such as fall from ladder, scaffold, roofs, falling object, struck by moving vehicle, contact by moving parts, etc. ORCA calculates the risk profile of a building construction site, consisting of thirty-eight workers in different job positions, such as operators of excavators, loaders, compaction equipment, workers in excavation and framing phases, etc. All risk profiles of workers have been quantified and jobs have been ranked according to their risk. Workers installing timber formworks have the highest fatality risk (1.57×10 −3 /yr), followed by the workers installing reinforcement (1.52×10 −3 /yr).

  9. The cost of occupational dose

    International Nuclear Information System (INIS)

    Fleishman, A.B.; Clark, M.J.

    1980-01-01

    The optimization of radiological protection will routinely involve the balancing of public and occupational exposure, particularly within the nuclear fuel cycle. For example the reduction of public exposure from an effluent stream could lead to increases in occupational exposure from treatment, storage and disposal operations. A methodology is propased for the estimation of the cost of occupational exposure in the UK (Pound man-Sv -1 ) based on valuations of changes in risk. A variable value for the cost of the occupational man-Sv is obtained depending on per caput dose levels. The values at particular per caput dose levels are different for occupational workers and the general public, because of different demography and assumptions on risk perception and aversion. They are however approximately the same when the per caput doses are expressed as percentages of the dose limits for workers and the general public respectively. An example of the application of the derived cost of the occupational man-Sv to an optimisation problem is given. (author)

    Full Text Available Occupational dermatoses contribute to a significant portion of work-related diseases, especially in Asia, where a major portion of the workforce is in the unorganized sector. This review article is focussed on the frequency and pattern of occupational skin diseases reported across Asian countries and type of allergens implicated in different occupations. The literature was searched systematically using key words 'occupational dermatoses,' 'occupational skin disease' and name of each Asian country. Ninty five full-text articles were considered relevant and evaluated. Some of the dermatoses seen in industrial workers in Asian countries are similar to those in Western countries, including dermatoses due to chromate in construction and electroplating workers, epoxy resin, and chromate in painters, wood dust in workers in the furniture industry, azo dyes in textile workers and formaldehyde and chromates in those working in the leather and dyeing industries, dermatoses in domestic workers, chefs and health-care workers. Dermatoses in workers engaged in agriculture, beedi (tiny cigars manufacture, agarbatti (incense sticks production, fish processing, carpet weaving, sanitation and those working in coffee plantations and coal mines appear to be unique to Asian countries. Recognition of clinical patterns and geographic variations in occupational skin diseases will provide an impetus to further strengthen future research in these areas, as well as improving their management.

  15. Occupational therapy practice in emergency care: Occupational therapists' perspectives.

    Science.gov (United States)

    Spang, Lisa; Holmqvist, Kajsa

    2015-01-01

    Emergency care takes place in a complex work environment that is characterized by critically ill patients, short hospital stays, and a wide variety of different healthcare professionals. Studies of occupational therapists' (OTs) experiences of working within emergency care have shown that they often experience difficulties in explaining the essence of occupational therapy and have to justify their approaches. Much effort has been made in Sweden to help OTs dispel the notion that occupational therapy is difficult to explain, and the aim of this study was to describe how Swedish OTs perceive their work in emergency care. A qualitative descriptive approach was taken, and 14 interviews were conducted with OTs working in emergency care. Qualitative content analysis was used to analyse the data. The overall theme that emerged was "Feeling established through deliberate occupation-based work". The underlying categories showed different strategies used by the OTs to provide occupational therapy in an emergency care context. Deliberate strategies were used to demonstrate the effectiveness of occupational therapy and its approaches to patients and other health care professionals, and this resulted in the OTs feeling both established and needed. Unlike the OTs in previous studies, the Swedish OTs experienced no difficulties in explaining occupational therapy and could make convincing arguments for their interventions. Parallel to their clinical work, the OTs worked with on-going development to find ways to improve their approaches. In summary, these Swedish OTs seem to have been provided with a professional language and the knowledge required to establish themselves in an emergency care setting.

    Although work management is no longer a new concept, continued efforts are still needed to ensure that good performance, outcomes and trends are maintained in the face of current and future challenges. The ISOE programme thus created an Expert Group on Work Management in 2007 to develop an updated report reflecting the current state of knowledge, technology and experience in the occupational radiological protection of workers at nuclear power plants. Published in 2009, the new ISOE report on Work Management to Optimise Occupational Radiological Protection in the Nuclear Power Industry provides up-to-date practical guidance on the application of work management principles. Work management measures aim at optimising occupational radiological protection in the context of the economic viability of the installation. Important factors in this respect are measures and techniques influencing i) dose and dose rate, including source- term reduction; ii) exposure, including amount of time spent in controlled areas for operations; and iii) efficiency in short- and long-term planning, worker involvement, coordination and training. Equally important due to their broad, cross-cutting nature are the motivational and organisational arrangements adopted. The responsibility for these aspects may reside in various parts of an installation's organisational structure, and thus, a multi-disciplinary approach must be recognised, accounted for and well-integrated in any work. Based on the operational experience within the ISOE programme, the following key areas of work management have been identified: - regulatory aspects; - ALARA management policy; - worker involvement and performance; - work planning and scheduling; - work preparation; - work implementation; - work assessment and feedback; - ensuring continuous improvement. The details of each of these areas are elaborated and illustrated in the report through examples and case studies arising from ISOE experience. They are intended to

    Full Text Available As a pre-processing technique, superpixel segmentation algorithms should be of high computational efficiency, accurate boundary adherence and regular shape in homogeneous regions. A fast superpixel segmentation algorithm based on Iterative Edge Refinement (IER has shown to be applicable on optical images. However, it is difficult to obtain the ideal results when IER is applied directly to PolSAR images due to the speckle noise and small or slim regions in PolSAR images. To address these problems, in this study, the unstable pixel set is initialized as all the pixels in the PolSAR image instead of the initial grid edge pixels. In the local relabeling of the unstable pixels, the fast revised Wishart distance is utilized instead of the Euclidean distance in CIELAB color space. Then, a post-processing procedure based on dissimilarity measure is empolyed to remove isolated small superpixels as well as to retain the strong point targets. Finally, extensive experiments based on a simulated image and a real-world PolSAR image from Airborne Synthetic Aperture Radar (AirSAR are conducted, showing that the proposed algorithm, compared with three state-of-the-art methods, performs better in terms of several commonly used evaluation criteria with high computational efficiency, accurate boundary adherence, and homogeneous regularity.

    This article presents a study of three asylum-seeking men from Iran and Afghanistan. It aimed to explore how and if they experienced occupations as occupations in a Danish asylum centre and how their life experience shaped their choice and value of current occupations. In-depth narrative interviews...... explored the participants’ occupational history and its influence on their occupations in the asylum centre. A thematic analysis showed that the participants had been subjected to occupational disruption and deprivation by politically oppressive systems even before their flight. Their occupations...... in Denmark were to a certain extent influenced by their earlier occupations and the current occupational deprivation they all experienced was due to limited possibilities in the centre. Although they tried their best to fill their days and create structure, there was a loss of valued occupations...

  1. La Defensa, Política de Estado

    2008-12-01

    Full Text Available The areas of the State Policy are set, specially focussing on the Defense as it is closely related to concepts like National Interest and Anglo-Saxon bipartisan policy. Nevertheless, the political alternation will cause differences. It is also necessary to tell the difference between the State Policy and the Policy carried out by the State. That’s why the democratic Parliaments play a fundamental role in shaping the defence policy. Although the Parliament symbolizes the National Sovereignty there can be and there are actually differences with the Public Opinion. This sort of divorce is not really new as, in Spain, it became evident in a very intensive way on the occasion of decisions such as the Spanish entry into the NATO. A State Policy related to Defense, kept during a long time and resistant to political alternation would certainly be the best instrument to reach a culture of defense.Se establecen los ámbitos de las políticas de estado, con especial énfasis en la Defensa al estar esta vinculada al concepto de interés nacional, y al anglosajón bipartisan policy. No obstante, la alternancia política va a crear discrepancias. Conviene diferenciar la “Política de Estado” y la “Política del Estado”. Por ello, los Parlamentos democráticos juegan un papel fundamental en la conformación de la política de defensa. Pese a que el Parlamento representa a la soberanía nacional pueden producirse, y de hecho se producen, discrepancias con la opinión pública. Este divorcio no es nuevo y en España se ha manifestado de forma muy intensa con ocasión de tomas de decisión como la incorporación a la OTAN. Una política de Estado en defensa, mantenida en el tiempo y resistente a las alternancias políticas sería el instrumento más adecuado para lograr una cultura de defensa.

    Full Text Available Las políticas públicas son hijas del crecimiento de los Estados posrrenacentistas y de las necesidades de planificación administrativa de sociedades de masas. Las políticas conservadoras afirman la subsidiariedad del Estado, se centran en la familia y en el temor a la democracia y a los sindicatos. Las liberales se anclan en la corrección de fallas del mercado y de contingencias biológicas. Las socialdemócratas, más ambiciosas, aspiran a una previsión de todas las contingencias y desigualdades ilegítimas, desde un Estado orientador del mercado y no subsidiario. Los Estados de Bienestar surgen del intento de superar recesiones, desempleo y malestar social desde la inversión, hasta deficitaria, de Estados que esperan luego recuperar su inversión. Las nociones de soberanía y de derechos humanos dificultan ese retorno y nutren un crecimiento progresivo de los imaginarios de consumo que erosionan un sistema inicialmente exitoso, desde que no son más inversiones e intervenciones de emergencia sino parte del cálculo de bienestares colectivos e individuales. Son víctimas de su éxito. Pese a que los neoliberales subrayan las insuficiencias teóricas y los fallos históricos de las políticas públicas clásicas, llegados al poder todos las aplican porque la cultura política los supone y enfrentarla sería electoralmente suicida. Hasta los marxistas lo hacen. Sin embargo, la sociedad de consumo y la cultura posmoderna van creando un progresivo hiato entre la moderna oferta tecnoburocrática iluminista de satisfactores, y la más reciente demanda, socialmente mucho más exigente y variada. Deberían disfrutar, por ende, de utilidad marginal político-electoral decreciente. Pero en la medida en que son apreciadas, no por su sustancia material, sino por el ‘reconocimiento’ simbólico que implican, y porque las poblaciones-objetivo han internalizado como legítimas las ofertas iluministas, paterno-maternales, las políticas públicas todav

    Full Text Available Background: Among the Model of Human Occupation (MOHO assessments, the Role Checklist is one of the most established. In spite of its widespread use, no studies have examined role examples and their association with the three embedded levels of doing, as established in the MOHO theory. Method: A cross-sectional survey of 293 respondents from the US, the UK, Japan, Switzerland, Sweden, and Norway produced 7,182 role examples. The respondents completed Part I of the Role Checklist and provided examples of each internalized role they performed. Responses were classified as occupational skill, occupational performance, or occupational participation. Results: Thirty-three percent of the examples were classified as examples of occupational participation, whereas 65% were classified as examples of occupational performance. Four roles linked mostly with occupational participation, another four roles linked mostly with occupational performance, and the two remaining roles were mixed between occupational participation and occupational performance. Discussion: The Role Checklist assesses a person’s involvement in internalized roles at the level of both occupational participation and occupational performance. There are differences among countries with regard to how roles are perceived and exemplified, and different roles relate differently to the occupational performance and occupational participation levels of doing. There are related implications for occupational therapists.

  4. The selection of occupancy factors

    An estimate of the proportion of time that an area is occupied by radiation workers is often used in radiological protection to permit relaxation of exposure rate limits above those for continuous occupation. This proportion is known as an occupancy factor and is used most frequently in X-ray facilities. The strategy for controlling the external exposure of radiation workers must be decided before occupancy factors are selected for the design of the radiation protection facilities. When shielding has to be designed the occupancy factor effects the design objectives and permits increased exposure rates at the shield surface. It is useful to note that the selection of occupancy factors with due regard to the expected spatial variation of the exposure rate can help to reduce the range of the worker's radiation exposure because field gradients are usually steeper close to the shield. When other hazards, such as internal exposure, and other constraints, such as cost of the space consumed, are added, the selection of the optimum set of occupancy factors is more difficult. Two zone occupancy factors are discussed in this paper and proposals are made for a strategy to be used when there is more than one hazard and the designer has to meet constraints imposed by limitations of the facilities available. An important feature of the strategy is the avoidance of high radiation exposure to small groups of workers. The errors involved in assessment of the actual dose received by the radiation worker must be taken into account and in particular the selection of the higher exposure rate limits must be made with attention to the accident potential

    Full Text Available Background: The aim of the paper was to present basic statistical data on occupational diseases diagnosed in 2012. Material and Methods: The work was based on the data from "Occupational Disease Reporting Forms" received by the Central Register of Occupational Diseases in 2012. The data comprised information on nosologic units, gender and age of patients, duration of occupational exposure, sections of the national economy and voivodeships. The incidence was specified in terms of the number of cases in relation to paid employees or to employed people. Results: The number of occupational diseases accounted for 2402 cases. The incidence rate was 23 cases per 100 000 paid employees. In spite of the general decline in the number of cases, the incidence of infectious and parasitic diseases increased by 8.6%. The highest incidence was noted for infectious and parasitic diseases (6.8/100 000, pneumoconioses (5.5/100 000, hearing loss (2.1/100 000, diseases of: the peripheral nervous system (2/100 000, voice disorders (1.9/100 000 and the musculo-skeletal system pathologies (1.1/100 000. The pathologies specified above accounted in total for 84% of all occupational diseases. The industrial sectors of the national economy characterized by the highest incidence included mining and quarrying (288.3/100 000 and manufacturing (27.8/100 000. The highest incidence was recorded in the Silesian (46.2/100 000 and the lowest in the Opolskie (4.2/100 000 voivodeships. Conclusions: The downward trend in the incidence of occupational diseases continues. Different incidence of voice disorders among teachers in individual provinces suggests that uniform preventive, diagnostic and certification standards are missing. Med Pr 2013;64(3:317–326

    The study of human occupation requires a variety of methods to fully elucidate its complex, multifaceted nature. Although qualitative approaches have commonly been used within occupational therapy and occupational science, we contend that such qualitative research must extend beyond the sole use of interviews. Drawing on qualitative methodological literature, we discuss the limits of interview methods and outline other methods, particularly visual methods, as productive means to enhance qualitative research. We then provide an overview of our critical ethnographic study that used narrative, visual, and observational methods to explore the occupational transitions experienced by immigrants to Canada. We describe our use of occupational mapping and participatory occupation methods and the contributions of these combined methods. We conclude that adopting a variety of methods can enable a deeper understanding of the tacit nature of everyday occupation, and is key to advancing knowledge regarding occupation and to informing occupational therapy practice.

    Unbelted occupants may increase the risk of injury for other occupants in a motor vehicle collision (MVC). This study evaluated the association between occupant restraint use and the risk of injury (including death) to other vehicle occupants. A population based cohort study. United States. MVC occupants (n = 152 191 unweighted, n = 18 426 684 weighted) seated between a belted or unbelted occupant and the line of the principal direction of force in frontal, lateral, and rear MVCs were sampled from the 1991-2002 National Automotive Sampling System General Estimates System. Offset MVCs were not included in the study. Risk ratios and 95% confidence intervals for injury (including death) for occupants seated contiguous to unbelted occupants compared to occupants seated contiguous to belted occupants. Risk ratios were adjusted for at risk occupant's sex, age, seating position, vehicle type, collision type, travel speed, crash severity, and at risk occupants' own seat belt use. Exposure to unbelted occupants was associated with a 40% increased risk of any injury. Belted at risk occupants were at a 90% increased risk of injury but unbelted occupants were not at increased risk. Risks were similar for non-incapacitating and capacitating injuries. There was a 4.8-fold increased risk of death for exposed belted occupants but no increased risk of death for unbelted occupants. Belted occupants are at an increased risk of injury and death in the event of a MVC from unbelted occupants.

    Mental health practice can create challenging environments for occupational therapists. This study explores the dynamic processes involved in the development and maintenance of professional resilience of experienced mental health occupational therapy practitioners. It presents the PRIOrity model that summarises the dynamic relationship between professional resilience, professional identity and occupation-based practice. A narrative inquiry methodology with two phases of interviews was used to collect the data from nine experienced mental health practitioners. Narrative thematic analysis was used to interpret the data. Professional resilience was linked to: (i) professional identity which tended to be negatively influenced in contexts dominated by biomedical models and psychological theories; (ii) expectations on occupational therapists to work outside their professional domains and use generic knowledge; and (iii) lack of validation of occupation-focussed practice. Professional resilience was sustained by strategies that maintained participants' professional identity. These strategies included seeking 'good' supervision, establishing support networks and finding a job that allowed a match between valued knowledge and opportunities to use it in practice. For occupational therapists professional resilience is sustained and enhanced by a strong professional identity and valuing an occupational perspective of health. Strategies that encourage reflection on the theoretical knowledge underpinning practice can sustain resilience. These include supervision, in-service meetings and informal socialisation. Further research is required into the role discipline-specific theories play in sustaining professional values and identity. The development of strategies to enhance occupational therapists' professional resilience may assist in the retention of occupational therapists in the mental health workforce. © 2012 The Authors Australian Occupational Therapy Journal © 2012

    Full Text Available Occupational skin cancer and precancerous lesions are skin disorders caused by exposure to chemical carcinogens such as polycyclic hydrocarbons and arsenic, or radiation, such as ultraviolet light and ionizing light in the workplace. Annual increase in skin cancer incidence is believed to be related to various factors such as frequent intense sunlight exposure (i.e. at work, recreational activities, and sun-tanning habit, ozone depletion, an increase in number of geriatric population, and an increase of public awareness in skin cancer. The most common occupational skin cancers are basal cell carcinoma, squamous cell carcinoma, and melanoma. Examples of occupational precancerous lesion of the skin are actinic keratosis and Bowen’s disease. Particular diagnostic criteria to diagnose occupational diseases has been developed. Early detection of occupational skin cancer and precancerous lesion is necessary. An effective prevention program consists of primary prevention such as prevention of hazardous material exposure, secondary prevention such as early detection of disease for early intervention, and tertiary prevention such as minimizing long-term impact of the disease.

    Full Text Available SUMMARY Objective: To analyze the epidemiological profile, risk factors in the workplace environment and prevention methods for professionals at risk of skin cancer. Method: A systematic review of articles on occupational skin cancer, published in the Lilacs, Scielo, Medline and Cochrane Library from January 1st, 2008, to December 31st, 2013, was performed. The search included the following terms: “neoplasias cutâneas” (DeCS, “exposição ocupacional” (DeCS, “epidemiologia” (DeCS as well as the keyword “prevenção”, and their equivalents in English. Results: After analyzing the titles and summaries of articles, the search strategy resulted in 83 references, of which 22 articles met the eligibility criteria. Discussion: We found that sun exposure is the main occupational risk factor for skin cancer, causing outdoor workers to be the most vulnerable to developing occupational skin cancer. Professionals with low levels of education and European descent are at increased risk of developing this cancer. Conclusion: Outdoor workers are more vulnerable to developing occupational skin cancer, estimating that professionals with low level of education and European descent are at increased risk of developing this cancer. Therefore, companies need to invest more in the health of workers by providing protective equipment and thus preventing occupational skin cancer.

  19. Ups and Downs of Poised RNA Polymerase II in B-Cells.

    2016-04-01

    Full Text Available Recent genome-wide analyses have uncovered a high accumulation of RNA polymerase II (Pol II at the 5' end of genes. This elevated Pol II presence at promoters, referred to here as Poll II poising, is mainly (but not exclusively attributed to temporal pausing of transcription during early elongation which, in turn, has been proposed to be a regulatory step for processes that need to be activated "on demand". Yet, the full genome-wide regulatory role of Pol II poising is yet to be delineated. To elucidate the role of Pol II poising in B cell activation, we compared Pol II profiles in resting and activated B cells. We found that while Pol II poised genes generally overlap functionally among different B cell states and correspond to the functional groups previously identified for other cell types, non-poised genes are B cell state specific. Focusing on the changes in transcription activity upon B cell activation, we found that the majority of such changes were from poised to non-poised state. The genes showing this type of transition were functionally enriched in translation, RNA processing and mRNA metabolic process. Interestingly, we also observed a transition from non-poised to poised state. Within this set of genes we identified several Immediate Early Genes (IEG, which were highly expressed in resting B cell and shifted from non-poised to poised state after B cell activation. Thus Pol II poising does not only mark genes for rapid expression in the future, but it is also associated with genes that are silenced after a burst of their expression. Finally, we performed comparative analysis of the presence of G4 motifs in the context of poised versus non-poised but active genes. Interestingly we observed a differential enrichment of these motifs upstream versus downstream of TSS depending on poising status. The enrichment of G4 sequence motifs upstream of TSS of non-poised active genes suggests a potential role of quadruplexes in expression

    DNA polymerase iota (Pol ι) is an error-prone DNA polymerase involved in translesion DNA synthesis (TLS) that contributes to the accumulation of DNA mutations. We recently showed that Pol ι is overexpressed in human esophageal squamous cell cancer (ESCC) tissues which promotes ESCC' progression. The present study was aimed at investigating the molecular mechanisms by which Pol ι enhances the invasiveness and metastasis of ESCC cells. We found that the expression of Pol ι is significantly higher in ESCCs with lymph node metastasis compared to those without lymph node metastasis. Kaplan-Meier analysis revealed an inverse correlation between Pol ι expression and patient prognosis. The expression levels of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9), two essential regulators of cells' invasiveness, were positively associated with Pol ι expression in ESCC tissues. Ectopic expression of Pol ι enhanced the motility and invasiveness of ESCC cells as evaluated by wound-healing and transwell assays, respectively. A xenograft nude mouse model showed that Pol ι promotes the colonization of ESCC cells in the liver, lung and kidney. Signaling pathway analysis identified the JNK-AP-1 cascade as a mediator of the Pol ι-induced increase in the expression of MMP-2/9 and enhancement of ESCC progression. These data demonstrate the underlying mechanism by which Pol ι promotes ESCC progression, suggesting that Pol ι is a potential novel prognostic biomarker and therapeutic target for ESCC.
