introduction: it has been reported that traumas such as transverse abdominal incision before myocardial ischemia result in a significantly decreased infarct size. this phenomenon is named remote preconditioning of trauma. since small skin burn is one of most common traumas, the effect of this injury on ischemia-induced arrhythmias and infarct size was investigated in a rat model of ischemia-rep...

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 incidence and severity of primary cardiac events are inversely related to the plasma concentration of high-density lipoproteins (HDLs). We investigated whether HDLs may exert a direct cardioprotection in buffer-perfused isolated rat hearts, which underwent a 20-minute low-flow ischemia followed by a 30-minute reperfusion. The administration of HDLs at physiological concentrations (0.5 and 1...

Nanobiotechnology is the assembling of biological molecules into nanodimension complexes. This has been used for the preparation of polyhemoglobin formed by the assembling of hemoglobin molecules into a soluble nanodimension complex. New generations of this approach include the nanobiotechnological assembly of hemoglobin, catalase, and superoxide dismutase into a soluble nanodimension complex. ...

SUDDEN CARDIAC ARREST IS THE most common lethal consequence of cardiovascular disease. Even if return of spontaneous circulation (ROSC) from cardiac arrest is achieved, approximately 60% of patients will not survive to hospital discharge. The high mortality is attributed to the postcardiac arrest syndrome, which involves global ischemiareperfusion injury, myocardial stunning, and anoxic brain i...

Purpose: To evaluate the protective effect, effective time window, and mechanism of protection sevoflurane post-conditioning late on heart muscle ischemiareperfusion (I/R) lesion in isolated rat heart.Methods: Langendorff perfusion model was established Sprague-Dawley (SD) rats. After 15 min stabilization, rats were assigned to 10 groups, based treatments given: control group (TTC), I/R group, ...

In emergency and critical care medicine, lung ischemia-reperfusion injury is a prevalent disorder, which has significant morbidity mortality. However, there still lack of effective means to block the injury. Established model mice; histological analysis scoring were helpful assess pathological in tissue; using an enzymelinked immunosorbent assay kit, expressed interleukin-6 interleukin-1 bronch...

The possible pathways of oxidative stress in anaerobic exercise includes transient and acute muscular deoxygenation, which resembles the ischemiareperfusion, xanthine oxidase activation, catecholamine autoxidation, and NADPH oxidase activation, prostanoid metabolism, phagocyte respiratory burst activity, disruption of iron containing proteins, and altered calcium homeostasis. 5 Mechanical stres...
