Experimental cerebral ischemia
Neurosurgery, 1980The basic concepts of the pathology and pathophysiology of cerebral ischemia are presented. Special emphasis is given to the changes that occur in the microcirculation and in autoregulation because of their primary role in the pathogenesis of cerebral infarction. The effects of adrenal steroids, barbiturates, and cerebral revascularization are reviewed.

MicroRNAs in Cerebral Ischemia
Translational Stroke Research, 2010Pathogenesis of cerebral ischemia has so far been described in the context of proteins and the pathways that they regulate. The discovery of biomarkers has also been focussed mainly on proteins and to some extent on the mRNAs that encode them. The knowledge on the role of microRNAs in understanding the pathogenesis of cerebral ischemia is still at its ...

Computerized Tomography, 1977
One hundred fifty-eight patients with cerebral ischemia, and divided into four clinical groups were studied with CT. The results were correlated with those of angiography, scintigraphy and regional cerebral blood flow measurement. CT evolution was closely correlated with clinical and anatomical evolution.

Pharmacotherapy of cerebral ischemia
Expert Opinion on Pharmacotherapy, 2009Ischemic stroke remains one of the leading causes of death and disability in the developed world. Despite many promising preclinical results, the only pharmacologic treatments proven effective in improving clinical outcome following ischemic stroke until now are administration of aspirin and acute thrombolysis using tissue-plasminogen activator.To ...

Cerebral Ischemia and Angiogenesis
Current Neurovascular Research, 2006Angiogenesis occurs in a wide range of conditions. As ischemic tissue usually depends on collateral blood flow from newly produced vessels, acceleration of angiogenesis should be of therapeutic value to ischemic disorders. Indeed, therapeutic angiogenesis reduced tissue injury in myocardial or limb ischemia.

Polyamines in cerebral ischemia
Neurochemical Pathology, 1988The present series of experiments was designed to study regional profiles of polyamines (putrescine, spermidine, and spermine) in reversible cerebral ischemia produced in rats and Mongolian gerbils. Polyamine profiles did not change during ischemia, but did following recirculation.

Microvascular Research, 1977
Abstract Total cerebral ischemia often injures or alters the microcirculation. This injury is highly variable within microregions, often resulting in different patterns of reperfusion within 100 μm. There is a growing consensus that the microcirculation injury is a consequence of ischemic brain injury rather than an essential pathogenetic step to it.

Cerebral ischemia and inflammation
Current Opinion in Neurology, 2001Cerebral ischemia is accompanied by a marked inflammatory reaction that is initiated by ischemia-induced expression of cytokines, adhesion molecules, and other inflammatory mediators, including prostanoids and nitric oxide. Preclinical studies suggest that interventions that are aimed at attenuating such inflammation reduce the progression of brain ...

Archives of Surgery, 1970
Eighteen of twenty patients with subclavian or innominate artery obstruction experienced episodes of transient cerebral arterial insufficiency; one patient suffered acute stroke and coma; all patients had angiographic evidence of subclavian or innominate artery obstruction; and most were shown to have retrograde flow in a vertebral artery. Two clinical

JAMA, 1961
Because of the sensitivity of the brain to hypoxia, acute cerebral ischemia due to operative or postoperative disruption of circulatory homeostasis, especially in older persons, should not be surprising. Six cases were selected to illustrate various peripheral circulatory mechanisms which, in conjunction with unrecognized preexisting cerebral vascular ...
