Epilepsy is characterized by the occurrence of repetitive seizures and can greatly affect a patient's cognition, particularly in terms of learning and memory. Orexin-A is an excitatory neuropeptide produced by the lateral hypothalamus that has been shown to be involved in learning and memory. A reduction in the levels of orexin-A after seizures may underlie the learning and memory impairments induced...
Endothelial dysfunction is associated with cardiovascular diseases. The Ca 2+ influx occurring via activation of plasmalemma Ca 2+ channels was shown to be critical in signaling the increase in endothelial permeability in response to a variety of permeability-increasing mediators. It has been reported that angiotensin II (AngII) could induce Ca 2+ signaling in some cells, and...
Angiotensin II (Ang II) is the main active peptide of the renin–angiotensin system (RAS), producing a number of inflammatory mediators that lead to endothelial dysfunction and the progression of atherosclerosis. Ang II-induced NF-κB nuclear translocation plays a pivotal role in this response. This study examines the NF-κB activation mechanism elicited by Ang II in human umbilical vein endothelial...
