The mechanism of antidepressant action, at the cellular level, is not clearly understood. It has been reported that chronic antidepressant treatment leads to an up-regulation of brain-derived neurotrophic factor (BDNF) mRNA levels in the hippocampus, and that physical activity (voluntary running) enhances this effect. We wished to investigate whether BDNF(More)
Elastase intratracheal instillation induces early emphysema in rodents. However, Syrian Golden hamsters develop more severe emphysema than Sprague-Dawley rats. We have reported species differences in oxidant/antioxidant balance modulating antiprotease function early after instillation. We now hypothesize that other components of the initial lung response to(More)
OBJECTIVES Critical limb ischemia complicates peripheral artery disease leading to tissue damage and amputation. We hypothesized that modifying adipose stromal cells (ASCs) to overexpress human vascular endothelial growth factor 165 (VEGF) would limit ischemic muscle damage to a larger extent than nonmodified ASCs. APPROACH AND RESULTS Rabbits with(More)
The handoff decision among heterogeneous wireless networks is a very important issue for integrating WLANs and cellular networks. Such networks exhibit different characteristics with respect to bandwidth, latency, power, and their charge model as well. In this paper, we present extensive numerical simulations of a novel vertical handover mechanism, which we(More)
Pharmacological attempts to alter the course of experimental pancreatitis in the opossum were made using synthetic 16, 16-dimethyl prostaglandin E2 (16, 16-dm PGE2). Anatomically, the opossum has an elongated ampulla resulting in a supraduodenal pancreatic duct-common bile duct junction allowing for bile reflux pancreatitis to be produced by ligating the(More)
