Jovens estudantes, interdisciplinaridade e multiculturalismo: um estudo em uma escola no meio rural
Este artigo apresenta resultados de uma prática pedagógica de ensino interdisciplinar desenvolvida em uma escola no meio rural localizada no Distrito de Amanhece, município de Araguari, MG, Brasil. Optou-se por trabalhar uma pedagogia de projeto para assim refletir sobre o multiculturalismo. Para avaliar essa prática pedagógica foi utilizada a técnica do grupo focal. Concluiu-se que, por um lado, o projeto cumpriu o seu papel, pois, envolveu os alunos que procuraram conhecer mais sobre a diversidade cultural. Por outro lado, observou-se que para o sucesso de uma educação multicultural faz-se necessária uma revolução em quatro pontos fundamentais: a) a formação de professores; b) o planejamento dos currículos; c) o desenvolvimento de materiais apropriados; d) a análise e a revisão crítica das práticas vigentes. Palavras-chave: Multiculturalismo. Interdisciplinaridade. educação e juventude.
Perfis de proteínas e carboidratos de silagem de capim 'Massai' com polpa cítrica peletizada e inoculante microbiano
The objective of this work was to evaluate the effects of the inclusion of pelleted citrus pulp and microbial inoculant on the fermentation characteristics, carbohydrate and protein fractionation, and total digestible nutrient contents of 'Massai' grass (Megathyrsus maximus × Megathyrsus infestus) silage. The experimental design was completely randomized, in a 2×4 factorial arrangement (application or not of inoculant × 0, 10, 20, and 30% citrus pulp) with five replicates. There was an increase in dry matter recovery as affected by citrus pulp levels. The values obtained for pH and ammonia nitrogen indicated an adequate fermentation process. Under increasing citrus pulp levels, there was a reduction in neutral detergent fiber and an increase in nonfibrous carbohydrate contents and in protein linked to fiber. Total digestible nutrient content reaches a peak of 513.1 g kg-1 with the inclusion of 12.50% citrus pulp. The microbial inoculant, when isolated, does not influence carbohydrate and protein profiles. Inclusions between 10 and 20% citrus pulp are able to maintain adequate fermentative parameters and improve the digestible nutrient profile, with an adequate dry matter recovery.O objetivo deste trabalho foi avaliar os efeitos das inclusões de polpa cítrica peletizada e de inoculante microbiano sobre características fermentativas, fracionamento de carboidratos e proteínas, e teores de nutrientes digestíveis totais de silagem de capim 'Massai' (Megathyrsus maximus × Megathyrsus infestus). O delineamento experimental foi inteiramente casualizado, em arranjo fatorial 2×4 (aplicação ou não de inoculante × 0, 10, 20 e 30% de polpa cítrica), com cinco repetições. Houve aumento da recuperação de matéria seca em função dos níveis de polpa cítrica. Os valores obtidos para pH e nitrogênio amoniacal indicaram adequado processo fermentativo. Sob níveis crescentes de polpa cítrica, houve redução dos teores de fibra insolúvel em detergente neutro e aumento do teor de carboidratos não fibrosos e proteína ligada à fibra. O teor de nutrientes digestíveis totais atinge ponto máximo de 513,1 g kg-1 com a inclusão de 12,50% de polpa cítrica. O inoculante microbiano, quando isolado, não influencia os perfis de carboidratos e proteínas. Inclusões entre 10 e 20% de polpa cítrica são capazes de manter parâmetros fermentativos adequados e melhorar o perfil de nutrientes digestíveis, com adequada recuperação de matéria seca
Whipple's Disease With Neurological Manifestations: Case Report.
Whipple's disease (WD) is an uncommon multisystem condition caused by the bacillus Tropheryma whipplei. Central nervous system involvement is a classical feature of the disease observed in 20 to 40% of the patients. We report the case of a 62 year old man with WD that developed neurological manifestations during its course, and discuss the most usual signs and symptoms focusing on recent diagnostic criteria and novel treatment regimens.62342-
Nutritive value of elephant grass hay ammoniated by urea
The aim of this study was to evaluate the effect of ammoniation by urea on the nutritional value of elephant grass hay harvested after flowering. A completely randomized design, in double factorial designs with an additional treatment: 4 urea doses (2, 4, 6 and 8%) x 2 treatment periods (30 and 45 days) + 1 (Control) with four replicates each, was employed. Dry matter, ash, ether extract, neutral detergent fiber, acid detergent fiber, cellulose, lignin, neutral detergent fiber corrected for the ash and the protein, total nitrogen, acid detergent insoluble nitrogen, neutral detergent insoluble nitrogen, non-protein nitrogen, in vitro gas production and carbohydrates fractionation were analyzed. The treatments influenced the contents of DM, EE, NDF, ADF, lignin, cellulose, NDFap, fraction A + B1, fraction B2, fraction C, TN, NPN, ADIN, NDIN, L and Vf2. There was a positive linear effect of urea dose for NDF, ADIN, NDIN and L, positive linear effect on fraction A + B1, NT and NPN, and positive quadratic effect for Vf2, with absolute maximum point of 4.5%. Elephant grass hay harvested after flowering has its nutritional value improved, with a minimum dose of 4.5% urea on a dry matter basis
COVID-Inconfidentes - SARS-CoV-2 seroprevalence in two Brazilian urban areas during the pandemic first wave: study protocol and initial results
Background: A population study is an important tool that can be used to understand the actual epidemiological scenario of the Covid-19 in different territories, identify its magnitude, understand its transmission dynamics, and its demographic, geographical, and social distribution.
Objective: The aim of this study was to determine the prevalence and dynamics of SARS-CoV-2 infection in the population of two Brazilian cities during the pandemic first wave and subsequent socioeconomic and health effects.
Materials & methods: This paper described the methodological procedures adopted and the prevalence of the SARS-CoV-2 infection in the population. A household survey was conducted between October and December 2020, in two historic cities of Brazil's mining region. Anti-SARS-CoV-2 antibody was detected using the Wondfo® rapid test. The face-to-face interview consisted of administration of a questionnaire containing registration data, sociodemographic and economic variables, living habits, general health condition, mental health, sleep habits, and eating and nutrition.
Results: We evaluated 1,762 residents, of which 764 (43.4%) were in Mariana and 998 (56.6%) in Ouro Preto. For both cities, 51.9% of the interviewees were female, with a predominance of the age range 35 to 59 years old (47.2%). The prevalence of the SARS-CoV-2 infection was 5.5% in all cities, 6.2% in Ouro Preto, and 4.7% in Mariana. The prevalence was similar between cities (P>0.05).
Conclusion: The study was effective in verifying the seroprevalence of infection by the virus and its findings will enable further analyses of the health conditions of the population related to social isolation and the risk of infection with SARS-CoV-2
Cirurgia bariátrica e a redução de Diabetes e Hipertensão Arterial Sistêmica: revisão de literatura
A obesidade atua como fator inflamatório importante no organismo humano, atuando e alterando significativamente a homeostase do indivíduo. Nesse contexto, a introdução da cirurgia bariátrica como prática terapêutica no controle de peso corporal tem se destacado como uma abordagem eficaz no tratamento da obesidade e suas comorbidades, incluindo diabetes mellitus tipo 2 (DM2) e hipertensão arterial sistêmica (HAS). Nesta revisão da literatura, exploramos estudos que investigam os efeitos da cirurgia bariátrica na redução do DM2 e da HAS, bem como os mecanismos subjacentes a essas melhorias. As buscas foram realizadas nas bases de dados PubMed, Scopus e Web of Science, utilizando termos de pesquisa relacionados à “cirurgia bariátrica”, “diabetes” e “hipertensão arterial sistêmica”. Dentre os estudos selecionados houve a constatação de uma sinalização benéfica do uso da cirurgia bariátrica no controle da obesidade e também na melhoria dos padrões pressóricos e também de redução da resistência insulínica. Conclui-se que a cirurgia bariátrica tem seu espaço no arsenal terapêutico de controle às patologias citadas, mas que sua indicação deve ser criteriosa e associada a melhora de hábitos de vida

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
