    Cardioprotective Properties Of Aerobic And Resistance Training Against Myocardial Infarction

    Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)We evaluated the effects of aerobic and resistance exercise training on ventricular morphometry and function, physical capacity, autonomic function, as well as on ventricular inflammatory status in trained rats prior to myocardial infarction. Male Wistar rats were divided into the following groups: sedentary+Sham, sedentary+myocardial infarction, aerobic trained+myocardial infarction, and resistance trained+myocardial infarction. Sham and myocardial infarction were performed after training periods. In the days following the surgeries, evaluations were performed. Aerobic training prevents aerobic (to a greater extent) and resistance capacity impairments, ventricular dysfunction, baroreflex sensitivity and autonomic disorders (vagal tonus decrease and sympathetic tonus increase) triggered by myocardial infarction. Resistance training was able to prevent negative changes to aerobic and resistance capacity (to a greater extent) but not to ventricular dysfunction, and it prevented cardiovascular sympathetic increments. Additionally, both types of training reduced left ventricle inflammatory cytokine concentration. Our results suggest that aerobic and, for the first time, dynamic resistance training were able to reduce sympathetic tonus to the heart and vessels, as well as preventing the increase in pro-inflammatory cytokine concentrations in the left ventricle of trained groups. These data emphasizes the positive effects of aerobic and dynamic resistance training on the prevention of the negative changes triggered by myocardial infarction.376421430Fundacao de Amparo a Pesquisa do Estado de Sao Paulo, Brazil [FAPESP - 2013/14788-9, FAPESP - 2014/06669-2]Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

    Universal procedure to cure future singularities of dark energy models

    Full text link
    A systematic search for different viable models of the dark energy universe, all of which give rise to finite-time, future singularities, is undertaken, with the purpose to try to find a solution to this common problem. After some work, a universal procedure to cure all future singularities is developed and carefully tested with the help of explicit examples corresponding to each one of the four different types of possible singularities, as classified in the literature. The cases of a fluid with an equation of state which depends on some parameter, of modified gravity non-minimally coupled to a matter Lagrangian, of non-local gravity, and of isotropic turbulence in a dark fluid universe theory are investigated in detail

    Os agricultores do Sul do Brasil cultivam uma grande diversidade de variedades crioulas de abóboras (Cucurbita moschata, C. maxima, C. pepo, C. ficifolia e C. argyrosperma).Os frutos de Cucurbita maxima são uma rica fonte de nutrientes importantes para a saúde humana, dentre os quais se destacam os carotenoides. O objetivo deste trabalho foi avaliar o teor de carotenoides totais em acessos de Cucurbita maxima do Banco Ativo de Germoplasma (BAG) de Cucurbitáceas da Embrapa Clima Temperado. Foram analisados nove acessos de variedades crioulas procedentes do Sul do Brasil. Para a determinação do teor de carotenoides totais foi utilizado o método de Talcott e Howard com modificações. Os resultados foram calculados através de uma curva padrão de ?-caroteno e expressos em ?g de ?-caroteno por gramas de amostra fresca. As médias obtidas para cada uma das determinações foram comparadas entre si pelo teste de Duncan a 5% de probabilidade. O acesso com maior valor médio de carotenoides totais apresentou 221,92 ?g/g, enquanto que o menor valor de carotenoides totais encontrado foi de 22,64 ?g/g. O BAG da Embrapa Clima Temperado conserva acessos de C. maxima com variabilidade genética para teores de carotenoides totais na polpa de frutos maduros
