Evaluation of ground maize grain silage rehydrated with water or whey: A sustainable storage option

The aim of this study was to assess the quality of ground maize grain silage rehydrated with varying proportions of whey, in comparison with silage rehydrated with water, to determine the potential of using whey during silage production as a strategy to enhance process sustainability. The treatments included four different rehydration methods for the ground maize, with the control treatment adding 30% water to the maize grain, and whey being used to rehydrate the maize at three different rehydration levels (20%, 30%, and 40% whey). The highest effluent losses were observed in the treatment with 40% whey rehydration (7.86 kg/t fresh matter), and the pH was highest in the control treatment (5.51). The silage rehydrated with water contained the fewest lactic acid bacteria (0.90 log colony-forming units/g) and the lowest lactic acid concentration (2.71 g/kg dry matter). Stability loss occurred fastest in the silage rehydrated with water (41.6 hours), followed by the silage rehydrated with 40% whey (46.4 hours). Rehydration with whey enhanced the quality of the ground maize silage, promoting greater sustainability in both the processing and production of grain silage.

Solanum sessiliflorum (mana-cubiu) antioxidant protective effect towards cholesterol oxidation: influence of docosahexaenoic acid

Harmful health effects have been attributed to cholesterol oxidation products (COPs). Factors that modulate their formation in foods are light, oxygen, heat, and food matrix (such as antioxidants content or unsaturation degree of lipids), among others. The objective of this work was to assess the effectiveness of an extract obtained from Solanum sessiliflorum (mana‐cubiu) (MCE) as a potential inhibitor of cholesterol oxidation under heating conditions. The influence of free DHA presence in the system was also evaluated. Results showed that MCE inhibited cholesterol degradation (44 vs. 18% without and with MCE, respectively) and reduced ninefold COPs formation in the absence of DHA. However, when DHA was present, the MCE was not effective toward cholesterol oxidation. In this case, MCE showed its antioxidant effect protecting DHA from degradation (89 vs. 64%)

Morfofisiologia do tecido intertubular e das células de Leydig de jaguatirica (Leopardus pardalis) adulta

Estudou-se o espaço intertubular e descreveu-se seu arranjo em jaguatirica adulta (Leopardus pardalis). Para tal, colheram-se fragmentos dos testículos, de cinco jaguatiricas adultas, provenientes de cativeiro, obtidos por biópsia incisional. O compartimento intertubular correspondeu a 19,4% do parênquima, sendo 3,9% ocupado por células de Leydig. Estes se apresentaram uninucleados, com o núcleo arredondado e nucléolo único, e com grande quantidade de grânulos pigmentares no citoplasma. O compartimento intertubular apresentou padrão do tipo II, e o tecido conjuntivo foi o componente mais abundante do tecido intertubular. Observou-se pequeno percentual de células de Leydig na espécie estudada, e o número médio por grama de testículo, 33,39 x10(6), apresentou-se dentro da amplitude descrita para a maioria dos mamíferos

Cinema: an humanist and pedagogical tool for themes in Health-Education. The experience of CineSocial

Study design: The approach to the research was qualitative. Objective: we used the audiovisual resources (movies) to make teachers, students and health professionals reflect, discuss and updatesocial subjects relevant to health and education. Methodology: The Project was structured as a coursewith five meetings that took place between 2008 August and December. Subjects relevant to PublicHealth and Education were focused (hunger, school violence, teenage pregnancy, health-disease process and teenage drug abuse); for each theme, specialists were invited. The instrument used to acquirethe participant perceptions was a questionnaire with 14 semi-structured questions and at the end ofeach meeting, a report was requested. A Thematic analysis of narrative was conducted with the materialfrom the individual reflection report. Results: The meeting had the presence of 49 participants (undergraduates, public teachers, health professionals, graduates and professors). In the analysis of thenarrative open question material from the individual reflection report, we could identify two sets of categories: the first one identified was the participants' expectancy before beginning the CineSocial project andthe second one identified was the participants' opinions about the course relevance. Discussion andConclusions: The cinema use enabled knowledge flow and experience diffusion; it also corroborated theidea that not only documentaries and fiction films could express the knowledge aimed by Science, butother types of cinema as well. Focusing on cinema was not the priority of this experience, the priority wasfocus on life, society, school, exclusion, current subjects present inside or outside of the school.Modelo do estudo: Abordagem qualitativa de pesquisa Objetivo: foi utilizado recurso audiovisual (filmes)para propiciar reflexões, discussões e atualização de professores, alunos e profissionais da saúde emtemas sociais pertinentes às áreas da saúde e educação. Metodologia: o projeto foi estruturado em formade curso de difusão com cinco encontros, entre agosto e dezembro de 2008. Foram abordados temasrelevantes em Saúde e Educação (fome, violência escolar, gravidez na adolescência, processo saúdedoença e drogas na adolescência) e foram convidados especialistas em cada temática para debate. Oinstrumento utilizado para captar as percepções dos participantes foi um questionário de 14 questõessemi-estruturadas e ao final de cada encontro foi solicitada a entrega de relatório. Foi realizada AnáliseTemática de Narrativa de material proveniente dos relatórios individuais de reflexão. Resultados: osencontros tiveram a presença de 49 participantes (estudantes de graduação, professores da rede municipal de ensino, profissionais da área da saúde, pós-graduandos e docentes do ensino superior). Naanálise do material narrativo advindo das questões abertas dos relatórios individuais de reflexão foipossível levantar dois blocos de categorias, sendo que o primeiro deles destacou as expectativas que osparticipantes tinham antes de iniciar o projeto CineSocial e o segundo bloco levantou a opinião dosparticipantes sobre a relevância do curso. Discussão e Conclusões: o uso do cinema possibilitou acirculação dos conhecimentos, tornou possível a difusão de experiências, corroborou a ideia de quedocumentários assim como filmes de ficção podem exprimir os conhecimentos orientados pela Ciência.Pensar a arte do cinema não foi a prioridade dessa experiência, a prioridade foi pensar a vida, a sociedade, a escola, a saúde, a exclusão social e temas do cotidiano presentes dentro ou fora das escolas
