Quadro hematologico e peso do baço de camundongos com tumor de Ehrlich na forma sólida tratados com Agaricus blazei

Este trabalho teve como objetivo avaliar a utilização do Agaricus blazei nas formas de filtrado e suspensão total aquosa (10mg/animal) na terapêutica de camundongos portadores de tumor de Ehrlich sólido, testando sua atividade anti-neoplásica. Os animais tratados diariamente com A. blazei apresentaram valores maiores dos parâmetros hematológicos (eritrograma e leucograma), e peso relativo final do baço quando comparados com o grupo controle (água destilada), porém sem diferença significativa (P>0,05)

Este estudo busca o entendimento dos processos hidrológicos e erosivos associados ao desenvolvimento de canais incisos do tipo voçoroca, conectadas a expansão da rede de canais no domínio dos vales de cabeceiras de drenagem, em resposta a mudanças de uso do solo decorrente da introdução de plantios de eucalipto em antigas áreas de pastagens

Study of comparative bioavailability among two formulations containing hydroxyzine hydrochloride in healthy volunteers after a single dose administration

The study was performed to compare the bioavailability of two hydroxyzine hydrochloride 25 mg tablet formulation in 16 volunteers of both sexes. The study was conducted open with randomized two period crossover design and a two weeks wash out period. Plasma samples were obtained over a 96 h interval. Hydroxyzine concentrations were analyzed by Liquid Chromatography with Tandem Mass Spectrometry (LC-MS/MS). Bioequivalence between the products was determined by calculating 90 % confidence intervals (90 % I.C) for the ratio of AUC0-t , AUC0-inf and Cmax values for the test and reference products, using logarithmic transformed data. The 90 % confidence intervals were 81.89-105.85 %, 84.61-105.30 %, and 84.04-108.66 %, respectively. Since the 90 % confidence intervals for Cmax , AUC0-t and AUC0-inf were within the 80-125 % interval proposed by the Food and Drug Administration, it was concluded that the two hydroxyzine hydrochloride formulations are bioequivalent in their rate and extent of absorption.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Total lipids, fatty acid composition, total cholesterol and lipid-soluble antioxidant vitamins in the longissimus lumborum muscle of water buffalo (Bubalus bubalis) from different production systems of the Brazilian Eastern Amazon

Research Areas: Agriculture ; Veterinary Sciences ; ZoologyThe aim of this study was to analyze the influence of distinct production systems and seasonal variation in the Brazilian Eastern Amazon on the meat lipid composition of water buffaloes. Water buffaloes were reared in commercial farms in the Eastern Amazon either in extensive systems (Marajó Island, Nova Timboteua and Santarém locations), during rainy or dry seasons, or intensive (feedlot) systems. Animals reared in extensive systems were fed natural pastures, and those reared in feedlots were fed sorghum silage and commercial pellets. Buffaloes were slaughtered and ribeye muscle (longissimus lumborum) samples collected. Lipid-soluble antioxidant vitamins and fatty acids were analyzed. The nutritional value of meat from buffaloes reared in Marajó Island extensive system during the rainy season was higher than that of other systems, as it had lower levels of cholesterol and higher amounts of α-tocopherol associated with higher hypocholesterolaemic/hypercholesterolaemic ratio and lower index of atherogenic. Also, this meat had lower percentages of saturated fatty acids and higher proportions of mono- and polyunsaturated fatty acids (PUFA), particularly n-3 PUFA, with increased PUFA/saturated fatty acids ratio and decreased n-6/n-3 PUFA ratio. However, all extensive systems produced meat with a relatively low index of thrombogenicity values, which is advantageous for human healthinfo:eu-repo/semantics/publishedVersio

Comparison of rally times and action effectiveness between professional volleyball and school sub-19

Este estudo teve como objetivo comparar os tempos de rally e o padrão de complexos e de ações realizados no voleibol profissional e escolar sub-19. Foram avaliados um jogo de voleibol masculino e feminino da Superliga Brasileira (voleibol profissional) e um jogo de uma equipa dos Jogos dos Institutos Federais (voleibol escolar sub-19) por meio do software Adobe®Premiere®Pro e analisou-se os tempos de rallies e seus intervalos, a percentagem (%) da densidade, os tipos e números de complexos e das ações nos rallies, além do ponto obtido no rally. Nos jogos de voleibol escolar sub-19 e feminino exibiram maiores tempo de rally e % da densidade, reduzindo o tempo de recuperação. No jogo de voleibol escolar sub-19 realizou-se um maior número de complexos no rally que o profissional. Os complexos com 3 e 1 ações foram os mais executados e exibiram maior ocorrência de pontos. O escalão dos sub-19 mostrou uma maior ocorrência de pontos por meio de erros de fundamentos (bloqueio, defesa e ataque), já nos jogos profissionais ocorreram mais pontos de ataque. Erros de serviço na superliga masculina foram mais relevantes que nas demais categorias. Conclui-se que o voleibol escolar sub-19 difere do profissional nos tempos de rallies e padrões dos complexos e ações, devido à menor experiência no desporto.info:eu-repo/semantics/publishedVersio

Promising prospective effects of Withania somnifera on broiler performance and carcass characteristics: A comprehensive review

Poultry production contributes markedly to bridging the global food gap. Many nations have limited the use of antibiotics as growth promoters due to increasing bacterial antibiotic tolerance/resistance, as well as the presence of antibiotic residues in edible tissues of the birds. Consequently, the world is turning to use natural alternatives to improve birds' productivity and immunity. Withania somnifera, commonly known as ashwagandha or winter cherry, is abundant in many countries of the world and is considered a potent medicinal herb because of its distinct chemical, medicinal, biological, and physiological properties. This plant exhibits antioxidant, cardioprotective, immunomodulatory, anti-aging, neuroprotective, antidiabetic, antimicrobial, antistress, antitumor, hepatoprotective, and growth-promoting activities. In poultry, dietary inclusion of W. somnifera revealed promising results in improving feed intake, body weight gain, feed efficiency, and feed conversion ratio, as well as reducing mortality, increasing livability, increasing disease resistance, reducing stress impacts, and maintaining health of the birds. This review sheds light on the distribution, chemical structure, and biological effects of W. somnifera and its impacts on poultry productivity, livability, carcass characteristics, meat quality, blood parameters, immune response, and economic efficiency
