Background and Objective: As one of the widely used drugs, aspirin (acetyl-salicylic acid, ASA) plays an important role in stroke treatment and prevention. In a previous study, we demonstrated ASA injection at 30 min after ischemia onset is neuroprotective. To determine whether the neurons protected by ASA had a normal ultrastructure, hippocampal CA1 pyramidal neurons were examined by Transm...

Aim: Oxidative stress plays a crucial role in the pathophysiology of ischemic stroke. Since water-solublefullerene derivatives act as the potent scavenger of oxygen free radicals in biological systems, we aimedto investigate the possible protective effects of fullerol nanoparticles on brain infarction and edema intransient model of focal cerebral ischemia in rat.Materials & Methods: Experiment ...

objective: it is generally agreed that most of the phenomena observed during brain ischemia and reperfusion can be explained by the damage to membrane structure. oxidative stress is resulted in an imbalance between high consumption of oxygen and low levels of endogenous antioxidants. it is known that gallic acid (ga) is a strong antioxidant. the present study was carried out to evaluate the eff...

objective: the risk of cardiac death in diabetic patients is 3 times more than non-diabetics. but it is not determined who need cardiac screening. about 41% of diabetic patients with silent ischemia are missed. the carotid intima-media thickness (cimt) and ankel brachial index are two independent,simple and non invasive method in vascular complications diagnosis in diabetic patients.the aim of ...

Objective(s):Ischemia is described as organs and tissues are destitute of oxygen due to decreased arterial or venous blood flow. Many mechanisms play role in cell death happened as a consequence of a new blood flow is needed for both cell regeneration and to clean toxic metabolites during ischemia and later. Lung damage induced by ischemia/reperfusion (I/R) is a frequent problem in lung transpl...

Summery. The aim — analysis of preliminary experience treatment COVID-19-associated acute lower limbs ischemia in elderly and senile patients.
 Materials methods. We examined 48 patients (age 60- 84 years). First group 16 with ischemia, second 32 chronic limb without coronavirus infection. .
 Results discussion. group’s had extended blood clotting time (more than 13-15 min). Other ind...

Objective: Oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. The beneficial effects of antioxidant nutrients, as well as complex plant extracts, on cerebral ischemia-reperfusion injuries are well known. This study was conducted to determine the effects of the hydro-alcoholic root extract of Withania coagulans on CA1 hippocampus oxidative damages followin...
