Stimulation of the delta(1)-opioid receptor confers cardioprotection to the ischemic myocardium. We examined the role of protein kinase C (PKC) after delta-opioid receptor stimulation with TAN-67 or D-Ala(2)-D-Leu(5)-enkephalin (DADLE) in a rat model of myocardial infarction induced by a 30-min coronary artery occlusion and 2-h reperfusion. Infarct size (IS) was determined by tetrazolium staini...
The adenosine A2b receptor (Adora2b) has been implicated in cardioprotection from myocardial ischemia. As such, Adora2b was found to be critical in ischemic preconditioning (IP) or ischemia/reperfusion (IR) injury of the heart. Whereas Adora2b is present on various cells types, the tissue-specific role of Adora2b in cardioprotection is still unknown. To study the tissue-specific role of Adora2b...
Remote ischemic preconditioning (RIPC) of the heart is exerted by brief ischemic insults affected on a remote organ or a remote area of the heart before a sustained cardiac ischemia. To date, little is known about the inter-organ transfer mechanisms of cardioprotection by RIPC. Exosomes and microvesicles/microparticles are vesicles of 30-100 nm and 100-1000 nm in diameter, respectively (collect...
Doxorubicin (Dox) is an antitumor agent used in cancer treatment, but its clinical use is limited due to cardiotoxicity. Although exercise training can defend against Dox-mediated cardiac damage, the means for this cardioprotection remain unknown. To investigate the mechanism(s) responsible for exercise training-induced cardioprotection against Dox-mediated cardiotoxicity, we tested a two-prong...
This review will summarize proteomic methods that are useful in studying the role of mitochondria in cardioprotection. The strengths and weaknesses of some of the different approaches are discussed. We focus on the cardiac mitochondrial proteome with emphasis on changes associated with cell death and protection, and we summarize how proteomic data have contributed to addressing the role of mito...
Oxygen is the main participant in redox reactions body and its deficiency can lead to organ dysfunction. Thus, a decrease blood flow certain region of myocardium patients with coronary heart disease cause attack. According experimental studies, early reperfusion reduces infarct size, clinical studies have shown that effective affected artery prevention re-occlusion basis for minimizing size mor...
Although anaesthesia itself is now very safe, perioperative cardiac complications during non-cardiovascular surgery are a major cause of morbidity and mortality, because of the increasingly high underlying prevalence of cardiovascular disease. Fortunately, although there is no "magic bullet", pharmacological intervention can reduce the risk. In particular, current evidence strongly supports the...
