HIGHLIGHTS Ischemia-reperfusion triggers acute kidney injury due to reactive oxygen species. Quercetin is an antioxidant flavonoid that modulate the Rennin-Angiotensin System. prevents tubular cell death, oxidation, and mitochondrial depolarization. interacts with angiotensin AT1 receptor.

Liver ischemia/reperfusion injury has been extensively studied during the last decades and has been implicated in the pathophysiology of many clinical entities following hepatic surgery and transplantation. Apart from its pivotal role in the pathogenesis of the organ's post reperfusion injury, it has also been proposed as an underlying mechanism responsible for the dysfunction and injury of oth...

introduction: ischemia-reperfusion (ir) injury involves a complex, interrelated sequence of events. generation of reactive oxygen species (ros) especially superoxide anion, during ir is reported. the present study was designed to investigate the effect of mn (iii) tetrakis (4- benzoic acid) porphyrin (mntbap), an active, stable, nontoxic, and cell permeable sod (super oxide dismutase) mimetic i...

conclusion the myocardial grayscale intensity, velocity and displacement can effectively reflect the situation of steiri in patients after cardiac operation, and ti (cvi) has a higher performance in discriminating between patients with and without steiri. background the timely diagnosis of presence or absence of reperfusion injury after cardiac operation is critical for the patient’s outcome. w...

An ischemia-reperfusion (I/R) injury of small intestine is a serious and common condition that result the blockage superior mesenteric artery (SMA) because significant clinical problems. This study evaluated effect Mesna on systemic induced by ischemia/reperfusion (IR) in also liver, kidney lung as remote organs. Forty Wistar albino rats were randomly divided into four groups: control, ischemia...

Objective: Ischemia-reperfusion (I-R) injury is defined as the paradoxical exacerbation of cellular dysfunction and death following restoration blood flow to ischemic tissues. In our study, it was aimed examine potential DNA effects liver IR with an experimental animal model. Material Methods: modeling done seven male New Zealand rabbits. Blood samples were taken before model, 30 minutes after ...

Reperfusion injury includes a spectrum of events, such as reperfusion arrhythmias, vascular damage and no-reflow, and myocardial functional stunning. The concept of reperfusion injury remains controversial with many proposed mechanisms when applied to humans, whereas in animal models, there are two main proposed mechanisms: calcium over-load and formation of oxygen free radicals. To prove that ...

Ischemia-reperfusion syndrome is defined as myocardial injury caused by the restoration of coronary flow. This phenomenon has a complex pathophysiology and results in a paradoxical reduction of the beneficial effect of myocardial reperfusion. Studies suggest that ischemia-reperfusion injury may account for up to 50% of the final size of a myocardial infarct. Vastarel MR (trimetazidine) is a pha...

Exocytosis of endothelial granules promotes thrombosis and inflammation and may contribute to the pathophysiology of early reperfusion injury following myocardial ischemia. TAT-NSF700 is a novel peptide that reduces endothelial exocytosis by inhibiting the ATPase activity and disassembly activity of N-ethylmaleimide-sensitive factor (NSF), a critical component of the exocytic machinery. We hypo...
