    RelaçÔes sociais entre indivĂ­duos estĂŁo pautadas pela experiĂȘncia de educação e formação que cada um traz consigo ao longo da vida, pelo modo como se constituem individual e coletivamente. A partir de Elias e da metodologia da histĂłria oral, o objetivo foi buscar nas memĂłrias de infĂąncia de sete mulheres, professoras de crianças, nascidas entre 1950 e 1970, a formação e a educação que se constituiu na infĂąncia em espaços privados e domĂ©sticos. Apreendeu-se que a escolha profissional tem vĂ­nculos com a educação feminina, normatizada por regras de controle e civilidade

    Echinodorus macrophyllus, commonly known as chapĂ©u-de-couro, is a medicinal plant used in folk medicine to treat inflammation and rheumatic diseases. In this work, we used short-term bacterial assays based on the induction of SOS functions to examine the genotoxicity and mutagenicity of an aqueous extract of E. macrophyllus leaves. Whole extract and an ethyl acetate fraction showed similar genotoxicity and caused an ~70-fold increase in lysogenic induction. The extract also gave a positive result in the SOS chromotest with an increase of 12-fold in ÎČ-Galactosidase enzymatic units. There was a strong trend towards base substitutions and frameshifts at purine sites in the mutations induced by the extract in Escherichia coli (CC103 and CC104 strains) and Salmonella typhimurium test strains (22-fold increase in histidine revertants in TA98 strain). Since reactive oxygen species may be implicated in aging process and in degenerative diseases, we used antioxidant compounds as catalase, thiourea and dipyridyl in the lysogenic induction test. All this compounds were able to reduce the induction factor observed in the treatment with chapĂ©u-de-couro, thus suggesting that the genotoxicity and mutagenicity were attributable to the production of reactive oxygen species that targeted DNA purines

    BACKGROUND: Bladder cancer is the fourth most frequent malignancy among Uruguayan men. A previous study from Uruguay suggested a high risk of bladder cancer associated with matĂ© drinking. We conducted an additional case-control study in order to further explore the role of non-alcoholic beverages in bladder carcinogenesis. METHODS: In the time period 1996–2000, 255 incident cases with transitional cell carcinoma of the bladder and 501 patients treated in the same hospitals and in the same time period were frequency matched on age, sex, and residence. Both cases and controls were face-to-face interviewed on occupation, tobacco smoking, alcohol drinking and intake of matĂ©, coffee, tea, and soft drinks. Statistical analysis was carried out by unconditional multiple logistic regression. RESULTS: Ever matĂ© drinking was positively associated with bladder cancer (odds ratio [OR] 2.2, 95% confidence interval [CI] 1.2–3.9) and the risk increased for increasing duration and amount of matĂ© drinking. Both coffee and tea were strongly associated with bladder cancer risk (OR for coffee drinking 1.6, 95% CI 1.2–2.3; OR for tea drinking 2.3, 95% CI 1.5–3.4). These results were confirmed in a separate analysis of never-smokers. CONCLUSION: Our results suggest that drinking of matĂ©, coffee and tea may be risk factors for bladder carcinoma in Uruguay

    Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

    Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

    Responsabilidade do profissional de saĂșde sobre a notificação de casos de violĂȘncia domĂ©stica

    A notificação da violĂȘncia domĂ©stica pelos profissionais de saĂșde contribui para o dimensionamento epidemiolĂłgico do problema, permitindo o desenvolvimento de programas e açÔes especĂ­ficas. O objetivo do trabalho foi verificar a responsabilidade desses profissionais em notificar a violĂȘncia, especialmente a domĂ©stica e as possĂ­veis implicaçÔes legais e Ă©ticas a que estĂŁo sujeitos. Assim, foi realizada pesquisa na legislação brasileira e cĂłdigos de Ă©tica da medicina, odontologia, enfermagem e psicologia. Quanto Ă  legislação, as sançÔes estĂŁo dispostas na Lei das ContravençÔes Penais, Estatuto da Criança e Adolescente, Estatuto do Idoso e na lei que trata da notificação compulsĂłria de violĂȘncia contra a mulher. TambĂ©m existem penalidades em todos os cĂłdigos de Ă©tica analisados. Conclui-se que o profissional de saĂșde tem o dever de notificar os casos de violĂȘncia que tiver conhecimento, podendo inclusive responder pela omissĂŁo
