BACKGROUND AND PURPOSE Perfusion CT has been used to assess the extent of blood-brain barrier breakdown. The purpose of this study was to determine the predictive value of blood-brain barrier permeability measured using perfusion CT for development of malignant middle cerebral artery infarction requiring hemicraniectomy (HC). METHODS We retrospectively identified patients from our stroke regi...

Topographical evaluation of aphasic brain lesions can enhance our knowledge of cognitive physiology and plasticity. This prospective study was conducted on 100 stroke-afflicted patients with aphasia admitted in Valie-Asr Hospital (Khorasan, Iran) in 2003. Topography of infarct lesions was detected by a neurologist based on the map of brain vascular territories in CT-scan. Aphasic lesions catego...

background: stroke is the third leading cause of invalidism and death in industrialized countries. there are conflicting reports about the effects of angiotensin ii on ischemia-reperfusion brain injuries and most data have come from chronic hypertensive rats. in this study, hypotensive and non-hypotensive doses of candesartan were used to investigate the effects of angiotensin ii at1 receptor b...

background: stroke is the third leading cause of death. hypothermia has been recognized as an effective method in reducing brain injury. in this study, we assessed the effects of granulocyte colony-stimulating factor (g-csf) as a neuroprotective agent and mild hypothermia on mortality, behavioral function, infarct volume, and brain edema in wistar rats. methods: forty male rats were used in fiv...

BACKGROUND AND PURPOSE This study evaluated the characteristics and natural history of patients with lacunar (small, deep) cerebral infarcts in a defined population for comparison of these characteristics to those in patients with nonlacunar infarcts. METHODS This is a population-based study in Rochester, Minnesota, from 1960 to 1984, that used the medical record-linkage system to identify an...

BACKGROUND Whether white-coat hypertension in older subjects is a benign condition or is associated with an increased risk for stroke remains uncertain. White-coat hypertension as a risk factor for stroke was investigated in relation to silent cerebral infarct in the older Japanese population. METHODS The prognosis for stroke was studied in 958 older Japanese subjects [147 normotensives (NT),...

Background: Nepeta dschuparensis Bornm (NP) is used as a medicinal herb in Iran. In traditional medicine, this herb is extensively employed for curing ailments such as cardiovascular diseases. NP has antioxidant and anti-inflammatory properties. This project examined the effects of the NP extract on cyclooxygenase-2 (COX-2) and interleukin-1β (IL-1β) protein levels and its efficacy in neuroprot...

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 ...
