O objetivo deste trabalho foi avaliar os efeitos do uso de interenxertos, com diferentes comprimentos, sobre o vigor de plantas de pessegueiro da cultivar Jubileu. Foram utilizados interenxertos da cultivar de baixo vigor, Granada, com 5, 10, 15 e 20 cm de comprimento. Avaliaram-se o crescimento vegetativo, a floração e a frutificação efetiva das plantas. O experimento foi conduzido em Pelotas, RS, de março de 2007 a dezembro de 2008. O crescimento vegetativo do pessegueiro 'Jubileu' está diretamente ...

Sexual dysfunction in the female has been associated with a decrease in androgen levels, which can be reversed by testosterone treatment, however, bearing the risk of adverse side effects. Nasally administered testosterone could be an effective method for androgenic treatment avoiding the first-pass intestinal and hepatic metabolism and side effects. Here we examined the effects of chronic intranasal administration of testosterone on sexual behavior in female capuchin monkeys (Cebus apella) that ...

Postnatal heart stem and progenitor cells are a potential therapeutic tool for cardiomyopathies, but little is known about the mechanisms that control cardiac differentiation. Recent work has highlighted an important role for microribonucleic acids (miRNAs) as regulators of cardiac and skeletal myogenesis. In this paper, we isolated cardiac progenitors from neonatal β-sarcoglycan (Sgcb)–null mouse hearts affected by dilated cardiomyopathy. Unexpectedly, Sgcb-null cardiac progenitors spontaneously ...

Sexual dysfunction in the female has been associated with a decrease in androgen levels, which can be reversed by testosterone treatment, however, bearing the risk of adverse side effects. Previously we found that intranasal application of testosterone led to an increase in proceptive behavior in female capuchin monkeys, which was still enhanced beyond treatment pointing to prolonged effects. Here, we sought to replicate our previous findings and to further examine possible prolonged effects of ...

This paper proposes a methodology to predict benzene uptake rate in ambient air, using passive samplers with Tenax TA. Variations in the uptake rate were found to occur as a function of the sampling time; and were greater at the beginning of sampling. An empirical model was obtained and values for uptake rate agree with literature. Concentration prediction errors can be minimized by using sampling times of 4 to 14 days, thus avoiding the influence of excessive uptake rates in the initial days and ...

Although Angelica archangelica is a medicinal and aromatic plant with a long history of use for both medicinal and food purposes, there are no studies regarding the antineoplastic activity of its root. This study aimed to evaluate the cytotoxicity and antitumor effects of the crude extract of A. archangelica root (CEAA) on breast cancer. The cytotoxicity of CEAA against breast adenocarcinoma cells (4T1 and MCF-7) was evaluated by a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide ( ...

Our data suggest that impaired activity of myeloperoxidase (MPO) may play an important role in the dysfunction of neutrophils from hyperglycemic rats. Neutrophil biochemical pathways include the NADPH oxidase system and the MPO enzyme. They both play important role in the killing function of neutrophils. The effect of hyperglycemia on the activity of these enzymes and the consequences with regard to Candida albicans phagocytosis and the microbicidal property of rat peritoneal neutrophils is evaluated ...
