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.

Introduction: Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-2 (Nox2) is one of the predominant sources of ROS production during myocardial ischemia-reperfusion and can be induced by angiotensin II. The evidence suggests that pharmacological blockers of renin-angiotensin system can exert direct tissue effects independent of their ability to regulate blood pressure. The mechanism...

The first case of novel corona virus disease (COVID-19) was reported in China and undoubtedly today this has rapidly crossed borders, infecting people throughout the world. There are heaps complications related to COVID-19 namely acute respiratory failure, liver kidney injury, bacterial fungal infections, septic shock. Vascular thrombosis is another burden that pilling on load its complications...

INTRODUCTION Acute mesenteric ischemia is a surgical emergency that entails complex, multi-modal management, but its epidemiology and outcomes remain poorly defined. The aim of this study was to perform a population analysis of the contemporary incidence and outcomes of mesenteric ischemia. METHODS This was a retrospective analysis of acute mesenteric ischemia in the state of Maryland during ...

purpose: to evaluate the effect of aamniotic mmembrane ttransplantation (amt) in the management of acute severe ocular chemical burns. methods: this randomized clinical trial was performed in eligible patients with grade iii & iv acute chemical burn who randomly received conventional medical therapy (15 eyes) versus combined medical & amniotic membrane transplantation (15 eyes). main outcome me...

The goal of this modeling research is to provide mechanistic insight into the effect of altered membrane kinetics associated with 5-12 min of acute global ischemia on the upper limit of cardiac vulnerability (ULV) to electric shocks. We simulate electrical activity in a finite-element bidomain model of a 4-mm-thick slice through the canine ventricles that incorporates realistic geometry and fib...

CONTEXT Observational studies of acute myocardial perfusion imaging in emergency department (ED) patients with chest pain have suggested high sensitivity and negative predictive value for acute cardiac ischemia, but use of this method has not been prospectively tested. OBJECTIVE To assess whether incorporating acute resting perfusion imaging into an ED evaluation strategy for patients with su...

cocaine is used by more than 14 million people worldwide, about 0.3 percent of the global population age is 15 to 64 years. after alcohol, cocaine is the most common cause of acute drug-related emergency department visits in the united states. cocaine consumption is more frequently associated with acute cardiovascular illness.  cocaine stimulates α 1 , α 2 , β 1 and β 2 adrenergic receptors thr...

CONTEXT Ischemia is an established cause of acute pancreatitis; however, acute pancreatitis has never been reported after cardiac arrest. CASE REPORT We report a case of acute pancreatitis following cardiac arrest with prolonged cardiopulmonary resuscitation in a 58-year-old man, the mechanism of which is likely to be ischemic. The patient developed severe ischemic encephalopathy, leading to ...
