It has been proposed that, in skeletal muscle, the angiogenic response to exercise may be signaled by the increase in muscle blood flow, via biomechanical changes in the microcirculation (increased shear stress and/or wall tension). To examine this hypothesis, we compared the change in abundance of vascular endothelial growth factor (VEGF), basic fibroblast(More)
This study investigates the effect of increased ventilation on the expression of messenger ribonucleic acid (mRNA) levels of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and transforming growth factor-beta1 (TGF-beta1) in the diaphragm of intact, awake, spontaneously breathing rats, compared with responses in paralysed,(More)
In six intact ewes, deep anaesthesia lasting 1-2 h was induced with pentobarbital given intravenously at the onset of oestrus. In a second group of six ovariectomized ewes, light pentobarbital anaesthesia was induced following a control period of 4 h and then maintained for 2, 3, or 4 h. No drug was given to control animals (seven in the first group, three(More)
Organophosphorus (OP) pesticide poisoning is a significant problem worldwide. Research into new antidotes for these acetylcholinesterase inhibitors, and even optimal doses for current therapies, is hindered by a lack of standardized animal models. In this study, we sought to characterize the effects of the OP pesticide parathion on acetylcholinesterase in a(More)
