Abstract The consequences of myocardial infarction (MI) are an increasing problem worldwide. Despite spectacular progress in the invasive treatment ischemic heart disease, ability to limit ischemia-reperfusion (I/R) injury remains largely unrealized. Recent studies have shown that stimulation opioid receptors may confer a cardioprotective effect against I/R injury. Levosimendan, inodilator, is ...

Up to now, over 1,000 experimental treatments found in cells and rodents have been difficult to translate to human ischemic stroke. Since ischemia and reperfusion, two separate stages of ischemic stroke, have different pathophysiological mechanisms leading to brain injury, a combination of protective agents targeting ischemia and reperfusion respectively may obtain substantially better results ...

Objective: The aim of this study was to investigate the potentially deleterious effect in vivo high-fructose feeding rats on ex hemodynamic recovery and infarct size isolated rat hearts subjected low-flow ischemia reperfusion.
 Methods: After Sprague-Dawley male with a (n=9), high-glucose (n=9) or standard diet for four weeks, were extirpated perfused Krebs-Henseleit solution 15 min; there...

To investigate the expression of autophagy markers brain cells and effect propofol on during myocardial ischemia-reperfusion in type 2 diabetic rats. 36 healthy male Sprague Dawley rats were randomly divided into 6 groups, each group, fed with high-sugar high-fat diet for 8 w intraperitoneal injection streptozotocin to prepare rat model diabetes. The groups are: sham operation ischemia reperfus...

Background: Calcium overload and free radical mediated damage in the mitochondria is the most important pathological changes associated with myocardial ischemic-reperfusion injury. The verapamil post-treatment has been previously reported to prevent reperfusion-induced myocardial injury but functional recovery may be delayed due to the drug's inherent direct myocardial depression effect. In the...

BACKGROUND Ischemia-reperfusion injury (IRI) is a major challenge in liver transplantation. The mitochondrial pathway plays a pivotal role in hepatic IRI. Levosimendan, a calcium channel sensitizer, was shown to attenuate apoptosis after IRI in animal livers. The aim of this study was to investigate the effect of levosimendan on apoptosis in human hepatocytes. METHODS Primary human hepatocyte...

BACKGROUND Recently, we observed that small-intestinal ischemia and reperfusion was found to entail a rapid loss of apoptotic and necrotic cells. This study was conducted to investigate whether the observed shedding of ischemically damaged epithelial cells affects IR induced inflammation in the human small gut. METHODS AND FINDINGS Using a newly developed IR model of the human small intestine...

objective(s) dracocephalum moldavica (d. moldavica) have been traditionally used as a cardiotonic agent in the folk medicine of some regions of iran. in the present study, effects of total extract of d. moldavica on ischemia/reperfusion induced arrhythmias and infarct size investigated in isolated rat heart. materials and methods the isolated hearts were mounted on a langendorff apparatus then ...

AIM To assess intestinal barrier function during human intestinal ischemia and reperfusion (IR). METHODS In a human experimental model, 6 cm of jejunum was selectively exposed to 30 min of ischemia (I) followed by 30 and 120 min of reperfusion (R). A sham procedure was also performed. Blood and tissue was sampled at all-time points. Functional barrier function was assessed using dual-sugar ab...

Abstract Background/Introduction In experimental studies, mild hypothermia (<35°C) has reduced infarct size [1], potentially through reperfusion injury [2], but human trials have been ambiguous [3]. Furthermore, a pressure-volume (PV) loop framework is the gold standard for assessing cardiac performance, invasive approach limits its clinical use. Therefore, we used porcine model of ische...
