Ischemic Tolerance in Uremic Rabbits
Background: Cardiac complications after myocardial infarction are believed to be worse in the presence of comorbidities; we tested whether experimentally induced prolonged uremia exacerbated myocardial necrosis in a rabbit preparation of ischemia-reperfusion injury. In addition, we examined if treatment with an angiotensin converting enzyme inhibitor (Enalapril, ENA, 3 mg/Kg, IV) could reduce p...
متن کاملMechanisms of Ischemic Induced Neuronal Death and Ischemic Tolerance
Stroke is the second leading cause of death and the primary cause of disability in humans. The phenomenon of ischemic tolerance perfectly describes the quote: “What does not kill you makes you stronger.’’ Ischemic preor postconditioning is actually the strongest known procedure to prevent or reverse delayed neuronal death. It works specifically in sensitive vulnerable neuronal populations, whic...
متن کاملIschemic Preconditioning Increases Myocardial Tolerance to Subsequent Ischemic Episodes
It has long been recognized that a brief episode of myocardial ischemia causes reversible myocyte injury, "reversible" being defined by the fact that early restoration of arterial flow prevents infarction and permits eventual restoration of normal myocardial structure, function, and metabolism. However, numerous studies during the last 15 years1-5 have revealed that complete recovery is not imm...
متن کاملImmune mechanisms in cerebral ischemic tolerance
Stressor-induced tolerance is a central mechanism in the response of bacteria, plants, and animals to potentially harmful environmental challenges. This response is characterized by immediate changes in cellular metabolism and by the delayed transcriptional activation or inhibition of genetic programs that are not generally stressor specific (cross-tolerance). These programs are aimed at counte...
متن کاملHypoxic Preconditioning-Induced Cerebral Ischemic Tolerance
Background and Purpose—The importance of bioactive lipid signaling under physiological and pathophysiological conditions is progressively becoming recognized. The disparate distribution of sphingosine kinase (SphK) isoform activity in normal and ischemic brain, particularly the large excess of SphK2 in cerebral microvascular endothelial cells, suggests potentially unique celland region-specific...
