Práticas artísticas no ensino básico e secundário

O crescimento carece de uma pedagogia, e educar é ao mesmo tempo algo de muito antigo, e de muito diferente. Neste ensejo, assinalam-se dois polos: o professor, os alunos. Mas a educação faz-se num contexto social, cultural, tecnológico, ambiental. Sobre isto conhecem-se alguns pontos de fixação que tornam a educação mais consequente e humanista. A Matéria-Prima, na Educação Artística, é exatamente o que parece: os materiais à espera de serem utilizados, os processos experimentados, as vivências significadas e sentidas. O professor de artes tem uma grande possibilidade de diferença.info:eu-repo/semantics/publishedVersio

Convergent synthesis and cruzain inhibitory activity of novel 2-(N `-benzylidenehydrazino)-4-trifluoromethyl-pyrimidines

To search for new cruzain inhibitors, the synthesis of a series of novel 2-(N`-benzylidenehydrazino)-4-trifluoromethyl-pyrimidines in a convergent manner is presented. The cruzain inhibitory activity of some of these compounds was evaluated and a binding model was proposed. All derivatives tested were active and the most significant inhibitory effect (80% at 100 mu M) and IC(50) value (85 mu M) were obtained from the 2-(N`-4-chloro-benzylidenehydrazino)-4-trifluoromethyl-pyrimidine. Although further structural optimization to improve solubility is necessary, the molecular docking studies suggest that these inhibitors occupy the S2 pocket without irreversible enzyme inactivation, through hydrophobic interactions, thus, indicating a desirable mode of interaction for the design of novel inhibitors.

Gênero e deficiência: interseções e perspectivas Gender and disability: intersections and perspectives

O campo de estudos feministas e de gênero tem avançado à medida que se articula com outras categorias de análise, tais como geração, classe, raça/etnia, orientação sexual, região e religião. Uma questão, contudo, permanece à revelia do esforço de interseção dessas categorias, a saber, a deficiência. Para tanto, busca-se aqui avaliar algumas das possibilidades de análise de fenômenos sociais e culturais nas quais se considera oportuno o diálogo entre os estudos feministas e de gênero com o campo de estudos sobre deficiência. Espera-se proporcionar maior visibilidade para o debate dessa questão, avaliando seu potencial analítico e político em vista da sua contribuição para as políticas públicas.<br>The field of feminist and gender studies has advanced while becoming linked with other categories of analysis, such as generation, class, race/ethnic groups, sexual orientation, region and religion. However, one issue still remains isolated from the effort of intersecting those categories, namely disability. Therefore, here we have sought to evaluate some of the possibilities to the analysis of social and cultural phenomena in which the dialog between feminist and gender studies and the field of disability studies is considered to be appropriate. It is expected that greater visibility will be provided to the debate on such issue by evaluating its analytical and political potential in view of its contribution to public policies

Increased interregional virus exchange and nucleotide diversity outline the expansion of chikungunya virus in Brazil

Abstract The emergence and reemergence of mosquito-borne diseases in Brazil such as yellow fever, zika, chikungunya, and dengue have had serious impacts on public health. Concerns have been raised due to the rapid dissemination of the chikungunya virus across the country since its first detection in 2014 in Northeast Brazil. In this work, we carried out on-site training activities in genomic surveillance in partnership with the National Network of Public Health Laboratories that have led to the generation of 422 chikungunya virus genomes from 12 Brazilian states over the past two years (2021–2022), a period that has seen more than 312 thousand chikungunya fever cases reported in the country. These genomes increased the amount of available data and allowed a more comprehensive characterization of the dispersal dynamics of the chikungunya virus East-Central-South-African lineage in Brazil. Tree branching patterns revealed the emergence and expansion of two distinct subclades. Phylogeographic analysis indicated that the northeast region has been the leading hub of virus spread towards other regions. Increased frequency of C > T transitions among the new genomes suggested that host restriction factors from the immune system such as ADAR and AID/APOBEC deaminases might be driving the genetic diversity of the chikungunya virus in Brazil

Omega-3 Blood Levels and Stroke Risk:A Pooled and Harmonized Analysis of 183 291 Participants from 29 Prospective Studies

BACKGROUND: The effect of marine omega-3 PUFAs on risk of stroke remains unclear. METHODS: We investigated the associations between circulating and tissue omega-3 PUFA levels and incident stroke (total, ischemic, and hemorrhagic) in 29 international prospective cohorts. Each site conducted a de novo individual-level analysis using a prespecified analytical protocol with defined exposures, covariates, analytical methods, and outcomes; the harmonized data from the studies were then centrally pooled. Multivariable-adjusted HRs and 95% CIs across omega-3 PUFA quintiles were computed for each stroke outcome. RESULTS: Among 183 291 study participants, there were 10 561 total strokes, 8220 ischemic strokes, and 1142 hemorrhagic strokes recorded over a median of 14.3 years follow-up. For eicosapentaenoic acid, comparing quintile 5 (Q5, highest) with quintile 1 (Q1, lowest), total stroke incidence was 17% lower (HR, 0.83 [CI, 0.76-0.91]; P&lt;0.0001), and ischemic stroke was 18% lower (HR, 0.82 [CI, 0.74-0.91]; P&lt;0.0001). For docosahexaenoic acid, comparing Q5 with Q1, there was a 12% lower incidence of total stroke (HR, 0.88 [CI, 0.81-0.96]; P=0.0001) and a 14% lower incidence of ischemic stroke (HR, 0.86 [CI, 0.78-0.95]; P=0.0001). Neither eicosapentaenoic acid nor docosahexaenoic acid was associated with a risk for hemorrhagic stroke. These associations were not modified by either baseline history of AF or prevalent CVD. CONCLUSIONS: Higher omega-3 PUFA levels are associated with lower risks of total and ischemic stroke but have no association with hemorrhagic stroke.</p
