Triggering mitochondrial radical release: a new function for NADPH oxidases.
Ischemic preconditioning describes a scenario in which brief intermittent periods of ischemia provide protection against subsequent ischemic injury.1 A number of elements in the signal transduction cascade mediating ischemic preconditioning have been identified. The opening of mitochondrial KATP channels is central for this process, as well as the subsequent release of reactive oxygen species (...
متن کاملHyperosmolar triggering of histamine release from human basophils.
Idiopathic reactions occurring during the infusion of hyperosmolar solutions, such as radiocontrast dyes, cause a significant number of deaths each year. These reactions are similar to those which follow mediator release during allergen-induced anaphylaxis. In attempting to explain these nonimmunologic reactions, we examined the direct effect of hyperosmolarity on normal human basophils with em...
متن کاملTriggering the Hf Breakdown of the Atmosphere by Barium Release
RF ionization rates for mixtures of air with bariurn are computed using a Fokker-Planck code. It is shown that there is an optimum mixing ratio of barium to air, significantly ower than unity, which maximizes the ionization rate for a given value of incident RF power density and frequency. Rocket injection of barium at a selected height reduces ignificant/y the RF breakdown threshold for the mi...
متن کاملFree Radical Scavenging Activity of Silymarin with Refrence to Depleted Uranium Induced Mitochondrial Dysfunction
Introduction: Recently depleted uranium is being widely used as anti-armour ammunition and at very high temperature, results in information of an aerosol of very small uranium oxide particles, which may be inhaled. It is alleged that these particles represent a new battlefield hazard because of the chemical toxicology and/or radioactivity. Method & materials: Male Wistar strain albino rats ...
متن کاملThe mitochondrial free radical theory of aging.
The mitochondrial free radical theory of aging is reviewed. Only two parameters currently correlate with species longevity in the right sense: the mitochondrial rate of reactive oxygen species (mitROS) production and the degree of fatty acid unsaturation of tissue membranes. Both are low in long-lived animals. In addition, the best-known manipulation that extends longevity, dietary restriction,...
