Leptin concentration was positively correlated with values for EMD, PEMD, FAT, PFAT, LW and PWT (P smaller than 0.001), whereas follistatin concentration was negatively correlated with values for EMD and PWT (P smaller than 0.001), and PEMD (P smaller than 0.01) and FAT (P smaller than 0.05). Leptin concentration was negatively related to age and positively related to live
weight at first oestrus and the proportion of females that attained puberty (P = 0.05), and to fertility and reproductive rate (P smaller than 0.01). Follistatin concentration was negatively related to live weight at first oestrus and to fertility (P smaller than 0.01) and reproductive rate (P smaller than 0.05). There were positive this website correlations (P smaller than 0.001) between muscle accumulation and leptin concentration, and between muscle accumulation and reproductive performance. We conclude that leptin and follistatin are probably both involved in effects of
accelerated accumulation of muscle and adipose tissues on the onset of puberty. (C) 2014 Elsevier B.V. All rights reserved.”
“Stroke is the leading cause of disability in adults and the second most common cause of mortality worldwide. There is currently intense interest in the use of natural products in the treatment of the condition. The aim of this study was to investigate the effect of Gualou Guizhi decoction (GLGZD) on rats subjected to cerebral ischemia/reperfusion injury and the possible mechanisms involved. Cerebral ischemia/reperfusion injury was induced selleck products by the middle cerebral artery occlusion method. Ischemic injury was assessed by estimating neurological function and measuring brain infarct volume, and the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method was employed to examine ischemia-induced apoptosis. The levels of the antioxidative enzyme superoxide dismutase (SOD) and the concentrations find more of the non-enzymatic scavenger glutathione (GSH) and malondialdehyde (MDA) were measured
to investigate the antioxidant mechanisms. In addition, the levels of excitatory amino acids (EAAs) and glutamate receptor 1 (GluR1) were examined using an automatic amino acid analyzer and immunohistochemical analysis. The administration of GLGZD attenuated the cerebral ischemia/reperfusion injury-induced neural deficits and cerebral infarct volume, reduced the levels of MDA and EAAs (glutamate and aspartate), significantly increased the activity of the antioxidant GSH and notably elevated the activity of SOD. Consistently, GLGZD inhibited ischemia-induced apoptosis and downregulated the expression of GluR1. In conclusion, this study suggested that GLGZD exerts a neuroprotective effect on focal cerebral ischemia/reperfusion injury through the modulation of multiple antioxidant and anti-excitotoxicity pathways.
