Background Elevated CRP and increased CCA-IMT are both associated with the occurrence of stroke. CRP and IMT are closely associated; the higher the CRP, the greater the carotid atherosclerosis as measured by carotid IMT. Objectives To study the relationship between elevated C-reactive protein as a blood biomarker and increased intimal media thickness of carotid artery, and its relation to infarct...
Background In acute ischemic stroke, collateral circulation plays an important role in maintaining blood flow to the tissue that is at risk of progressing into ischemia, and in increasing the successful recanalization rate without hemorrhagic transformation. Objectives To compare between collaterals in patients with extracranial carotid stenosis alone and in patients having both extracranial and...
Background Brain perfusion is most likely to be impaired in border zone regions, and clearance of emboli will be most impaired in these regions of least blood flow. Severe occlusive disease of the internal carotid artery causes both embolization and decreased perfusion as well as some cardiac diseases that cause microembolization. Objectives To differentiate between hypoperfusion and microemboli...
The genetic diversity of the HBV S gene has a significant impact on the prophylaxis and treatment of hepatitis B infection. The effect of selective pressure on this genetic alteration has not yet been studied in Iranian blood donors. To explore HBV evolution and to analyze the effects and patterns of hepatitis B surface antigen (HBsAg) mutations on blood screening assays, 358 Iranian blood donors...
