Safranal is a monoterpene aldehyde found in saffron (Crocus sativus L.) petals. It has been previously reported that safranal has a wide range of activities such as antioxidant and anti-inflammatory effects. In this study, we examined the effect of safranal on brain injuries in a transient model of focal cerebral ischemia. Transient focal cerebral ischemia was induced by middle cerebral artery ...

PURPOSE We aim to characterize infarct volume evolution within the first month post-ischemic stroke and to determine the effect of recanalization status on early infarct volume estimation. METHODS Ischemic stroke patients recruited for the MONITOR and VISION studies were retrospectively screened and patients who had infarcts on diffusion-weighted imaging (DWI) at baseline and had at least two...

BACKGROUND Myocardial perfusion single photon emission computed tomography (MPS) is frequently used as the reference method for the determination of myocardial infarct size. PERFIT(R) is a software utilizing a three-dimensional gender specific, averaged heart model for the automatic evaluation of myocardial perfusion. The purpose of this study was to compare the perfusion defect size on MPS, as...

Background and Objective: Recent studies suggest that sub-lethal ischemia protect the brain from subsequent ischemic injuries. This study was an effort to identify and shed light on the nature of changes in the blood brain barrier permeability and brain edema. Materials and Methods: Rats were divided into four main experimental groups, each of 21 animals. The first group acted as a model of isc...

In the mouse model of permanent, middle cerebral artery occlusion, infarct volume varies widely across inbred strains but generally is inversely correlated with collateral vessel number. However, we also observed certain mouse strains that share similar collateral vessel anatomy but exhibit significantly different infarct volume. To identify genetic factors determining infarct volume in a colla...

objective(s):to investigate the effects of local mild hypothermia on the expression of fas, fasl and mmp-3 after cerebral ischemia-reperfusion in rats. materials and methods:male wistar rats were divided into sham-operated group (sham), normothermia group (nt), and hypothermia group (ht). mcao/r model was established by longa’s method, and reperfusion was allowed after 2 hr occlusion. mild hypo...

Background and Purpose—Reduction in infarct volume is the standard measure of therapeutic success in animal stroke models. Reduction in infarct volume has been advocated as a biological surrogate or auxiliary outcome measure for human stroke clinical trials to replace or supplement deficit, disability, and global clinical scales. However, few studies have investigated correlations between infar...

BACKGROUND AND PURPOSE In ischemic stroke, MR perfusion-weighted imaging (PWI) and diffusion-weighted imaging (DWI) mismatch represents tissue at risk for infarction. Infarct growth should only take place in the presence of mismatch, although there have been reports of this occurring. We hypothesized that this observation may be attributable to the presence of undetected "hidden mismatch," whic...
