Abstract Ischemic brain injuries are accompanied by the long-term changes in gene expression hippocampus, limbic system structure, involved regulation of key aspects higher nervous activity, such as cognitive functions and emotions. The altered genes proteins encoded them may be related to development post-ischemic psycho-emotional disturbances. Activation neuroinflammation following stroke hip...

introduction: in the current study, protective effect of natural honey applied during ischemia/reperfusion (i/r) was studied on infarct size in ischemic heartheart. methods: ischemic hearthearts (n=8 per group) were mounted on a langendorff apparatus at constant pressure then subjected to 30 min regional ischemia followed by 120 min reperfusion. in control group, the hearts were perfused by a m...

BACKGROUND Ectonucleotidase plays an important role in the regulation of cardiac function by controlling extracellular levels of adenine nucleotides and adenosine. To determine the influence of ischemia-reperfusion injury on ectonucleotidase activity in coronary vascular bed, we compared the metabolic profile of adenine nucleotides during the coronary circulation in pre- and post-ischemic heart...

The objective of this study was to assess the influence of the ACE gene insertion (I)/deletion (D) polymorphism on plasma ACE activity; blood pressure; and risk of myocardial infarction, ischemic heart disease, and ischemic cerebrovascular disease by comparing small and large studies. The meta-analyses are based on a literature search of MEDLINE up until April 1998 and assessment of bibliograph...

BACKGROUND We have previously reported that ischemic preconditioning increases 5'-nucleotidase activity and adenosine release during ischemia and reperfusion. However, its direct cause-and-effect relation has not been proven. To test the idea that the infarct size-limiting effect of ischemic preconditioning is blunted by inhibition of ectosolic 5'-nucleotidase activity, we assessed 5'-nucleotid...

Electroencephalography is a sensitive indicator for measuring brain condition, and can reflect early changes in brain function and severity of cerebral ischemia. However, it is not yet known whether electroencephalography can predict development of post-cerebral infarction depression. A total of 321 patients with ischemic stroke underwent electroencephalography and Hamilton Depression Rating Sc...

The sensitivity of carnitine palmitoyl coenzyme A (CoA) transferase I to inhibition of its activity by malonyl-CoA is progressively reduced in mitochondria isolated from ischemic cardiac cells as blood flow decreases to 30% or less of the preocclusion flow. The activity of carnitine palmitoyl-CoA transferase I in mitochondria isolated from nonischemic cardiac cells demonstrates incomplete inhib...

Gαi-coupled receptors play important roles in protecting the heart from ischemic injury. Regulator of G protein signaling (RGS) proteins suppress Gαi signaling by accelerating the GTPase activity of Gαi subunits. However, the roles of individual RGS proteins in modulating ischemic injury are unknown. In this study, we investigated the effect of RGS6 deletion on myocardial sensitivity to ischemi...
