Background and Aim: Cardiovascular diseases are the leading cause of morbidity and mortality worldwide. Increased histamine level in the cardiac tissue has deleterious effects after ischemia-reperfusion occurrence. Regarding the existence of histamine type 2 receptors in the heart and their decisive role in inflammation, in the present study the cardioprotective effects of ranitidine in the fac...
OBJECTIVE To investigate the cardioprotective effects of isoflurane and exendin-4 against myocardial ischemia/reperfusion injury and the signaling pathways through which these effects are mediated. MATERIALS AND METHODS For infarct size measurements, anesthetized mice were subjected to 30 min of coronary artery occlusion followed by 2 h of reperfusion. Wild-type or caveolin-3 knockout mice re...
Pharmacological agents suggested for infarct size limitation have serious side effects when used at cardioprotective doses which hinders their translation into clinical practice. The solution to the problem might be direct delivery of cardioprotective drugs into ischemic-reperfused myocardium. In this study, we explored the potential of silica nanoparticles for passive delivery of adenosine, a ...
The present study was designed to investigate the modulatory effects of rottlerin on ischemia reperfusion induced myocardial injury. Isolated rat hearts were exposed to 30 min of global ischemia followed by 120 min of reperfusion using Langendorff apparatus. Myocardial injury was assessed in the terms of infarct size, release of lactate dehydrogenase (LDH), creatine kinase (CK) enzymes. Rottler...
BACKGROUND Urocortin is a novel cardioprotective agent that can protect cardiac myocytes from the damaging effects of ischemia/reperfusion both in culture and in the intact heart and is effective when given at reperfusion. METHODS AND RESULTS We have analyzed global changes in gene expression in cardiac myocytes after urocortin treatment using gene chip technology. We report that urocortin sp...
Cannabinoids can mimic the infarct-reducing effect of early ischemic preconditioning, delayed ischemic preconditioning, and ischemic postconditioning against myocardial ischemia/reperfusion. They do this primarily through both CB1 and CB2 receptors. Cannabinoids are also involved in remote preconditioning of the heart. The cannabinoid receptor ligands also exhibit an antiapoptotic effect during...
background: the cardioprotective effect of ischemic preconditioning has been known for many years. since the temporary ischemia in the heart may cause lethal cardiac effects, the idea of creating ischemia in organs far from the heart such as limbs was raised as remote ischemic preconditioning (ripc). we hypothesized that the extension of ripc has more cardioprotective effect in patients undergo...
