background: embolus is one of the causes of ischemic stroke that can be due to cardiac sources such as valvular heart diseases and atrial fibrillation and atheroma of the aorta. transesophageal echocardiography (tee) is superior in identifying potential cardiac sources of emboli. due to insufficient data on tee findings in ischemic stroke in iran, the present study was done to evaluate tee in d...

background: impact of high level of uric acid on stroke is still controversial. we conducted this study to investigate the relationship between acute ischemic non-embolic stroke and serum levels of uric acid. methods: this was a case-control study on patients with acute ischemic non-embolic stroke in rafsanjan, iran. the control group consisted of normal persons who were similar to the case gro...

increased levels of proinflammatory cytokines have been recorded after the onset  of transient  or  permanent  brain  ischemia and  are  usually associated with  exacerbation  of ischemic injury. embolic stroke model is more relevant to the pathophysiological situation in such  patients, because the  majority of  ischemic injuries in humans  are induced  by old thrombi that originate from the h...

myxomas, the most common primary cardiac tumors, are known as a source of cardiogenic emboli. the possibility of their early detection has made them of great importance for emergency medicines. detection of the disease is probable at early stages using echocardiography and associate complications such as syncope, cerebral embolic ischemic strokes, and sudden death. we report experience of a rar...

objective(s) opioid abuse is still remained a major mental health problem, a criminal legal issue and may cause ischemic brain changes including stroke and brain edema. in the present study, we investigated whether spontaneously withdrawal syndrome might affect stroke outcomes. materials and methods addiction was induced by progressive incremental doses of morphine over 7 days. behavioral signs...

Background & Aims: Ischemic postconditioning, conducted by a series of brief occlusion and release of the bilateral common carotid arteries, has neuroprotective properties in permanent or transient models of middle cerebral artery (MCA) occlusion but its delayed neuroprotective effects in the embolic model of stroke, especially in female rat, have not yet been reported and were investigated ...

BACKGROUND AND PURPOSE This study uses T(2)* weighted imaging (T2*WI) to measure the temporal evolution of cerebral angiogenesis in rats subjected to embolic stroke up to 6 weeks after stroke onset with or without sildenafil treatment. Method- Male Wistar rats were subjected to embolic stroke and treated with saline (n=10) or with sildenafil (n=11), with treatment initiated at 24 hours and cont...
