Brain tolerance and preconditioning.
In this review article the authors describe a phenomenon of "brain tolerance" which represents transient resistance of brain tissue to a lethal insult established by preconditioning with a mild insult of short duration. Tolerance evoked by brief ischemia resembles transient ischemic attack(s) (TIA) often preceding full-blown ischemic stroke in a clinical setting. A series of recent studies have...
متن کاملIschemic preconditioning in the brain.
physiologic responses to its environment is important for survival. Certain organs respond to sub-lethal exposures to hypoxia or ischemia by a variety of physiologic mechanisms. Some of these mechanisms induce a greater tolerance to a subsequent exposure to hypoxia or ischemia. This phenomenon is described as ischemic or hypoxic preconditioning.1,2 It is nature’s “what doesn’t kill you makes yo...
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...
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 کاملRemote Ischemic Preconditioning and Diabetic Macular Edema
Objective: Remote Ischemic Preconditioning (RIPC) as the transient ischemia and reperfusion of the arm is a promising method for protecting different tissue from future ischemia. These effects might be mediated through vascular and endothelial growth factor (VEGF) pathway. We investigated the influence of RIPC on diabetic macular edema (DME) as a chronic ischemic condition in patients who were ...
