ischemic stroke accounts for about 87 percent of all cases. it occurs as a result of an obstruction within a vessel of the brain and sudden loss of blood circulation to the corresponding area resulting in the loss of brain function. it is caused by thrombotic or embolic occlusion of an artery and is more common than hemorrhagic stroke. we know that most of the injuries after an acute ischemic s...

Background: Activated normal platelets undergo many biochemical and morphological changes, some of which are apoptotic. Platelet derived microparticles and shrinked platelets as hallmark of platelet activation and apoptosis disperse surfaces containing procoagulant activity around injured vessels and tissues. This study was conducted to determine microparticles formation and platelet shrinkage ...

T restoration of coronary flow after an acute myocardial infarction (AMI) has been the most remarkable advance in the treatment of acute coronary syndromes in recent decades. Pharmacological and mechanical ways of achieving rapid and complete reperfusion of epicardial arteries have been the goal of many clinical trials. Questions such as whether PCI is superior to fibrinolysis, or if bolus lyti...

Membranous microparticles (MP) appearing in the supernatant plasma of stored platelet concentrates (PC) were analyzed by flow cytometry. Two populations of MP were arbitrarily delineated by light scatter as larger or smaller than 0.5 micron fluorescent beads. An estimate of MP concentration was obtained by adding a known amount of fluorescent beads to each sample before analysis of a set number...

Gastric infection by Helicobacter pylori is considered a risk factor for gastric and duodenal cancer, and extragastric diseases. Previous data have shown that, in a non-enzymatic way, H. pylori urease (HPU) activates neutrophils to produce ROS and also induces platelet aggregation, requiring ADP secretion modulated by the 12-lipoxygenase pathway, a signaling cascade also triggered by the physio...
