Despite higher sulphate concentration, the microbial metabolism was greatly compromised or absent in the acidified slurry. This could be explained by the high concentration

of protonized short-chained volatile fatty acids in the acidified slurry (approximately 25 mM, compared to untreated slurry <0.1 mM), which act as an uncoupling agent of the cell membrane potential and thereby arrest microbial metabolism. In total the consequences of slurry acidification are greatly reduced production GSK1120212 nmr rates and loss of sulphide and methane, and eliminated loss of ammonia. On the other hand, increased volatilization and loss of smelly fatty acids is to be expected. (C) 2008 IAgrE. Published by Elsevier Ltd. All rights reserved.”
“Evaluation for endocrine function is a pivotal part of the male infertility workup. Endocrine dysfunction may result from endogenous and exogenous sources. This article describes the traditional roles that the hypothalamic-pituitary-gonadal endocrine axis plays in spermatogenesis and testicular dysfunction, as well as other insults that may contribute to hypospermatogenesis. Recent research into the role alternative hormonal axes play in spermatogenesis

and promising new technologies that may correct inborn or acquired endocrinopathies leading to impaired sperm growth and maturation are discussed.”
“Honokiol, a novel antitumor agent, could induce P005091 supplier apoptosis and inhibit the growth of vascular endothelium in several tumor cell lines and xenograft models. It has been suggested that the antitumor effect of chemotherapy could be increased by combining

it with an antiangiogenesis agent in anticancer strategy. The present study explored the potential to increase the antitumor effect of adriamycin by combining it with honokiol in mouse 4T1 breast cancer models, and the underlining mechanism was investigated. Honokiol was encapsulated in liposomes to improve the water insolubility. In vitro, liposomal honokiol inhibited the proliferation of 4T1 cells via apoptosis and significantly enhanced the apoptosis of 4T1 cells induced by adriamycin. In vivo, the systemic administration FK506 supplier of liposomal honokiol and adriamycin significantly decreased tumor growth through increased tumor cell apoptosis compared with either treatment alone. Collectively, these findings suggest that liposomal honokiol may augment the induction of apoptosis in 4T1 cells ill vitro and in vivo, and this combined treatment has shown synergistic suppression in tumor progression according to the analysis of isobologram. The present study may be important in future exploration of the potential application of the combined approach in the treatment of breast cancer. Copyright (C) 2008 John Wiley & Sons, Ltd.
