11. A study of potassium channel activation as a pharmacological principle for vasodilation of cerebral blood vessels
Abstract : Increasing [K+]o is intimately coupled to progressive ischemia and reduced CBF. In isolated cerebral and mesenteric arteries, it was found that significant differences in the vascular responses to [K+]o exist. Among the species studied, human cerebral arteries were the most sensitive artery to increasing [K+]o. READ MORE

12. Signal Transduction in Focal Cerebral Ischemia : Experimental Studies on VEGF, MAPK and Src family kinases
Abstract : Cerebral ischemia elicits a wide range of events, including complex activation of various intracellular signaling pathways. This study aims to investigate the expression of vascular endothelial growth factor (VEGF) and the activation pattern of mitogen-activated protein kinases (MAPK) in reponse to focal cerebral ischemia.

13. Brain-derived neurotrophic factor in cerebral ischemia: a quantitative study on surviving and newly formed neurons
Abstract : This study explores the role of brain-derived neurotrophic factor (BDNF) for neuronal vulnerability and neurogenesis following cerebral ischemia in the rat. Cerebral ischemia results in selective neuronal cell loss in specific brain regions. We here demonstrate the rank order of vulnerability in two regions affected by global forebrain ischemia, i.

14. Stroke, Sex and Vascular Receptor Changes in the Brain
Abstract : Stroke is a severe cerebrovascular disease in which the neuronal tissue and vasculature of the brain undergo ischemia-evoked alterations. We have demonstrated an increased expression of cerebrovascular contractile receptors in the brain. This is hypothesized to mitigate cerebral blood flow and exacerbate tissue damage after stroke.

15. Electrical Bioimpedance Cerebral Monitoring: Fundamental Steps towards Clinical Application
Abstract : Neurologically related injuries cause a similar number of deaths as cancer, and brain damage is the second commonest cause of death in the world and probably the leading cause of permanent disability. The devastating effects of most cases of brain damage could be avoided if it were detected and medical treatment initiated in time. READ MORE
