introduction: during hemorrhagic shock (hs), the kidneys are one of the primary target organs involved. oxidative stress is shown to be enhanced in different models of acute kidney injury (aki). remote ischemic preconditioning (rpc) by brief limb ischemia is considered to be a safe method to protect different organs from further damage. in this study, we investigated the effects of brief hind l...

Background: Central renin angiotensin system has an important role on the cerebral microcirculation and metabolism. Our previous work showed that inhibition of angiotensin converting enzyme (ACE) activity prior to induction of ischemia protected the brain from severe ischemia/reperfusion (I/R) injuries. This study evaluated the impacts of post-ischemic inhibition of ACE, enalapril, on brain inf...

This review summarizes the data on anti-ischemic activity of carnosine. The pronounced anti-ischemic effects of carnosine in the brain and heart are due to the combination of antioxidant and membrane-protecting activity, proton buffering capacity, formation of complexes with transition metals, and regulation of macrophage function. In experimental cerebral ischemia, carnosine decreases mortalit...

BACKGROUND Brain thrombin activity is increased following acute ischemic stroke and may play a pathogenic role through the protease-activated receptor 1 (PAR1). In order to better assess these factors, we obtained a novel detailed temporal and spatial profile of thrombin activity in a mouse model of permanent middle cerebral artery occlusion (pMCAo). METHODS Thrombin activity was measured by ...
