    Diante do advento das novas tecnologias e suas diversas possibilidades de uso, verifica-se que várias instituições estão começando a ofertar seus programas educacionais a distância. O curso de Administração a distância da Universidade Federal de Santa Catarina destinado aos funcionários do Banco do Brasil, servidores da UFSC e outros servidores públicos. O curso possui 650 alunos, divididos em 10 pólos de ensino em todo o Estado de Santa Catarina. Quanto à metodologia de estudo, esta pesquisa pode ser classificada como: qualitativa, descritiva, teórica aplicada, estudo de caso, documental, bibliográfica, ex-post facto e participante. Conclui-se, portanto que o ambiente virtual pode trazer interatividade e um espaço organizado para o aluno, podendo a vir facilitar sua aprendizagem. Destaca-se ainda que este é um software livre, e passível de evolução contínua. Além disso, o Ministério da Educação apresenta indicativo para adoção do software Moddle em todos os programas da Universidade Aberta do Brasil

    Type 1 diabetes (T1D) is the result of the selective destruction of the pancreatic β-cells by T cells of the immune system. Although spleen is a secondary lymphoid organ, it is also involved in the T1D pathogenesis. However, the alterations in a variety of cellular processes of this disease need to be further understood. We aimed to analyze the benefits of resveratrol, and its complexed form on diabetic complications in the spleen of rats. To this end, we investigated important enzymes of phosphoryl transfer network, and Na+, K+-ATPase activity. Wistar rats were divided into non-diabetic groups: Control, Ethanol, Resveratrol, Hydroxypropyl-β-cyclodextrin, Resveratrol-hydroxypropyl-β-cyclodextrin, and diabetic groups with the same treatments. Diabetes was induced by a single dose of 60 mg/kg of streptozocin intraperitoneally, and treatments by intragastric gavage once daily for 60 days. Hyperglycemia reduced creatine kinase activity, which was reversed by the administration of resveratrol. Na+, K+-ATPase activity was greatly affected, but it was reversed by resveratrol and resveratrol-hydroxypropyl-β-cyclodextrin. This suggest an energetic imbalance in the spleen of diabetic rats, and in case this also occurs in the diabetic patients, it is possible that resveratrol supplementation could be beneficial to the better functioning of the spleen in diabetic patients

    Pela análise de prontuários médicos de instituição para tratamento de alienados, dirigida por uma associação de seguidores do espiritismo de orientação kardecista, identificam-se as diferentes percepções e estratégias de tratamento e administração social da loucura desenvolvidas por setores da população brasileira na primeira metade do século XX, numa região interiorana do país. Enfatiza-se o aspecto multidimensional da experiência da loucura, tomando-a como acontecimento sociocultural capaz de produzir diferentes análises e interpretações por grupos heterogêneos de atores sociais, que irão interpretá-la a partir de seus sistemas próprios de significação e entendimento._________________________________________________________________________________ ABSTRACT: Through analysis of the medical charts from an institution for treatment of the insane run by an association of Kardecist spiritists, it is possible to identify the various perceptions and strategies for treatment and social control of insanity developed by different sectors of the Brazilian population in the first half of the twentieth century in the Brazilian countryside. The multidimensional aspect of the experience of insanity is stressed, as it is a sociocultural event capable of different analyses and interpretations by heterogeneous groups of social actors, who interpret it based on their own systems of meaning and understanding

    Pervasive gaps in Amazonian ecological research

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
