background and objective: the circle of willis (cow) supports adequate blood supply to the brain. the cardiovascular system, in the current study, is modeled using an equivalent electronic system focusing on the cow. method: in our previous study we used 42 compartments to model whole car- diovascular system. in the current study, nevertheless, we extended our model by using 63 compartments to ...

the anti-ischemic effect of aqueous and ethanolic extracts of nigella sativa l. seed was studied using a four-vessel occlusion model in rats. the ischemia was evaluated by optical and transmission electron microscopy. after 20 min of forebrain ischemia, agents were administered intraperitoneally after reperfusion. both extracts comprised an alkaloid. in ischemic rats, the aqueous (1 g/kg) and e...

Purpose: Doing plyometric training with and without the vessel occlusion is an effective practice for rapid increase of muscles strength their hypertrophy. We evaluated the effects of plyometric training with and without the vessel occlusion on electromyographic parameters. Methods: In this quasi-experimental study, 22 females were selected through convenience sampling method. They were random...

various neurological complications occur in primary or secondary antiphospholipid syndrome (aps) consisting of cerebrovascular attacks, ocular events, dementia, seizure, chorea, and transverse myelopathy that are all related to the titer of antiphospholipid antibodies (apl). we report a patient with chorea and retinal vessel occlusion as manifestations of systemic lupus erythematosus (sle) and ...

results in all groups ischemic changes were apparently observed in hippocampus ca1 neurons. in two-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 14.9% and 23.2%, respectively. in four-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 7.6% and 44.9% (p < 0.0001), respectively. background an appropriate animal m...

BACKGROUND AND PURPOSE The purpose of this study was to evaluate whether bright vessel appearance on arterial spin labeling (ASL) MRI can help localize arterial occlusion sites in patients with acute ischemic stroke. METHODS Patients who underwent MRI for suspected acute ischemic stroke, as identified by an area of restricted diffusion, were included. All images were visually analyzed for the...

background :in addition to diagnosing the acute myocardial infarction (mi), stratifying high-risk patients and proper treatment strategies are important issues in managing patients complaining of chest pain and suspecting mi. many studies have been conducted to predict the occlusion site by interpreting the st segment deviations in electrocardiogram (ecg).additional posterior and right precordi...
