Stroke is one of the leading causes death and disability worldwide. However, treatment options for ischemic stroke remain limited. Matrix-metalloproteinases (MMPs) contribute to brain damage during strokes by disrupting blood-brain barrier (BBB) causing edemas. Carnosine, an endogenous dipeptide, was found us others be protective against injury. In this study, we investigated whether carnosine ...
Background: Ultrasound (US) has been used in neuroprotection after cerebral ischemia, however the mechanism of action remains unclearly. We have previously shown the protective effect of ultrasound on infarction volume and brain edema in ischemic brain injured at normothermic condition. Ultrasound may also amplify the effect of fibrinolytic medications in thrombolysis process .We have also show...
Pituitary adenylate cyclase activating polypeptide is a pleiotropic neuropeptide. We previously showed that heterozygous PACAP gene knockout (PACAP(+/-)) mice had larger infarct volumes and worse neurological scores after middle cerebral artery occlusion (MCAO). However, the relationship between endogenous PACAP levels and edema in the ischemic brain has not yet been evaluated. In this study, t...
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...
The use of intravenous tissue plasminogen activator (tPA) in the treatment of ischemic stroke is limited by its propensity to exacerbate brain edema and hemorrhage. The mechanisms underlying these deleterious effects of tPA remain incompletely understood. The purpose of this study was to delineate a pathway of tPA-mediated complement cascade activation in stroke and to determine whether complem...
AIM To explore the possibility of brain imaging by microcomputed tomography (microCT) using x-ray contrasting methods to visualize mouse brain ischemic lesions after middle cerebral artery occlusion (MCAO). METHODS Isolated brains were immersed in ionic or nonionic radio contrast agent (RCA) for 5 days and subsequently scanned using microCT scanner. To verify whether ex-vivo microCT brain ima...
