Brazilian Morus nigra

Morus nigra has been used popularly for several proposes, including diabetic. In an attempt to support medicinal value, the acute hypoglycemic, hypolipidemic, and antioxidant effects of the ethanolic extract of Morus nigra (EEMn 200 or 400 mg/kg b.w.) were evaluated in normal and alloxan-induced diabetic treated for 14 days. Serum biochemical and antioxidant analysis were performed at the end of experiment. Oral glucose tolerance test was performed at 10th and 15th days. Chromatographic analysis by HPLC-DAD of EEMn was performed. Insulin was used as positive control to glycemic metabolism as well as fenofibrate to lipid metabolism. EEMn (400 mg/kg/day) reduced fasting and postprandial glycaemia, improved oral glucose tolerance, and reduced lipolysis and proteolysis in diabetic rats. EEMn decreased the blood levels of total cholesterol and increased HDL level when compared to the diabetic control rats. At higher levels, EEMn reduced triglycerides and VLDL levels in diabetic rats. Also, EEMn reduced malondialdehyde and increased the reduced glutathione levels in liver of diabetic rats. Chromatographic analysis identified the presence of the flavonoids rutin, isoquercetin, and kaempferitrin. Acute EEMn treatment reduced hyperglycemia, improved oral glucose tolerance, and minimized dyslipidemia and oxidative stress leading to a reduction in atherogenic index in alloxan-induced diabetic rats

O Movimento Negro do ABC Paulista: diálogos sobre a prevenção das DST/aids

OBJETIVO: Apresentar a avaliação realizada sobre as possibilidades de integração entre as agendas do movimento negro e a prevenção das DST/aids. METODOLOGIA: Utilizou-se o instrumento qualitativo chamado de Panel Delphi, dada a sua flexibilidade de consultas. Foram cadastradas 135 entidades do movimento negro, tendo 41 delas aceitado a proposta de participar do painel de questões. O projeto foi extensivo aos sete municípios da região do ABC paulista, sendo que 32,8% do total da população da região é composta de pretos e pardos. RESULTADOS: O grupo de 41 entidades participantes propôs-se a atuar em ações de prevenção das DST/aids diretamente (agregando-as às suas atividades cotidianas), ou indiretamente (através de ações de controle social) e avaliou a necessidade de um entendimento sócio-histórico da vulnerabilidade da população negra, em relação não somente à prevenção de DTS/aids, mas também da saúde como um todo e da totalidade da vida: "[...] a história do negro é de desumanização, negação da condição de ser humano, que expõe os negros a qualquer doença. A informação fica sem credibilidade vinda dessa maneira. O negro precisa ser visto como ser pleno." (1.10.1). CONCLUSÕES: O racismo vivenciado tem impacto nas condições de acesso à saúde e tem se refletido na maior vulnerabilidade de homens e mulheres negros para a infecção de HIV. Os elementos de afirmação da identidade racial contribuem para a promoção da saúde da população negra. Ações conjuntas entre os serviços de saúde e o movimento social possibilitam condições de fortalecimento de uma política de enfrentamento das DST/aids entre as negras e os negros brasileiros.OBJECTIVE: To present the integration possibility evaluation (between the agendas of the black movement with the themes of health, particularly in relation to prevention of STD/AIDS). METHODS: We used the qualitative instrument called the Delphi Panel, given its flexibility to consultations with stakeholders with different power resources. 135 were registered entities of the black movement: 41 of them agreed to participate in the panel of questions. The project was extended to seven cities in the ABC region, bringing together 655,886 inhabitants (browns and blacks), who represent 32.8% of the total population of the region. RESULTS: The group of 41 participating (grass-roots organizations) proposed to act in actions of prevention of STD/AIDS directly (by adding them to their daily activities) or indirectly (through actions of social control) and assessed the need to understand socio-history of the greater vulnerability of the black population, not only in relation to the prevention of STD/AIDS, but also of health as a whole and the totality of life: "[...] the history of black dehumanization is a denial of the condition to be human, which exposes blacks to any disease. The information is unreliable, if coming this way. Blacks must be seen as a whole. CONCLUSIONS: The racism is understood as something that precedes any other, it has an impact on the access to health and has been reflected in the greater vulnerability of black men and women to HIV infection. The elements of affirmation of racial identity contribute to promoting the health of black people. Joint actions between health services and social movements provide conditions to strengthen a policy of confronting STD/AIDS among black women and black men, all Brazilians

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
