OBJECTIVE To investigate the influence of infarct zone viability on remodelling after late recanalisation of an occluded infarct related artery. METHODS A subgroup of 26 volunteers from TOAT (the open artery trial) underwent dobutamine stress cardiovascular magnetic resonance at baseline to assess the amount of viable myocardium present with follow up to assess remodelling at one year. TOAT s...
background: hyperthyroidism as a risk factor for stroke is not conclusive. there are no definite data on the relationship between ischemic cerebrovascular injury and hyperthyroidism. this study was designed to define whether the outcomes of post-ischemic stroke injury are influenced by chronic hyperthyroidism. methods: two groups of hyperthyroid (ht) and control euthyroid rats of equal numbers ...

Introduction: The purpose of this study was to determine Na-Ca exchanger 2, 3 (NCX2, 3) protein level changes during 2, 5, 10, 15 days after induction of normobaric hyperoxia (HO) preconditioning. Materials and Methods: Rats were divided in two experimental groups. The first group was exposed to 95% inspired HO for 4 h/day for 6 consecutive days (HO). The second group acted as control, and was...
BACKGROUND Propofol is neuroprotective when administered immediately after stroke. The therapeutic window, duration of administration, and antioxidant mechanisms of propofol in neuroprotection are not known. The effects of propofol after stroke were examined in the conscious animal. The authors have previously shown that light propofol anesthesia (25 mg x kg(-1) x h(-1)) for a period of 4 h, ev...
BACKGROUND AND PURPOSE We evaluate associations between the severity of magnetic resonance perfusion-weighted imaging abnormalities, as assessed by the hypoperfusion intensity ratio (HIR), on infarct progression and functional outcome in the Diffusion and Perfusion Imaging Evaluation for Understanding Stroke Evolution Study 2 (DEFUSE 2). METHODS Diffusion-weighted magnetic resonance imaging a...
objective(s): electrical inhomogeneity between ischemic and non ischemic myocardium is the basis of arrhythmia which occurs following coronary artery occlusion. the leakage of potassium from the ischemic region to the non ischemic region is very effective in the generation of these arrhythmias. the aim of this study is to research the effect of atp-dependent potassium (katp) channel blocker (gl...
introduction: black pepper (piper nigrum l.) is one of the medicinal plants being used to prevent and manage stroke in persian medicine. current findings support its anti-inflammatory, radical scavenging and neuroprotective characteristics. in this study, we aimed to evaluate role of black pepper on functional and histopathological outcomes of stroke in an animal model of mcao. materials and me...
