It was known for a while that some bactericidal antibiotics put bacterial respiration into over-drive, which, by producing too many oxygen radicals
, becomes toxic to the pathogens.
Prior Information Notice: Provision of highly sensitive oxygraf enabling simultaneous measurements of oxygen consumption polarographically and mitochondrial membrane potential, production of antibiotics and oxygen radicals
Evidence for the counterintuitive idea that oxygen radicals
are beneficial came from experiments in which researchers gave animals an antioxidant called N-acetyl cysteine.
New insights into mechanisms of endothelial dysfunction, such as a better understanding of the regulation of important vascular sources of oxygen radicals
, may lead to novel therapeutic strategies with the potential to improve prognosis.
Neutralising oxygen radicals
(free radicals), where they occur in excess in the body.
Burning of carbohydrates and lipids for providing energy in biological systems cause formation of free oxygen radicals
The studies on curing reaction of NR revealed that once heated DCP would dissociate to two isopropylbenzene oxygen radicals
in neutral medium, and RO radical could not react with the C = C of polyisoprene.
The chemicals generate oxygen radicals
from the light energy, destroying the cancer cells.
These metabolic reactions normally result in the formation of free oxygen radicals
, which play a role in the defense against foreign substances and infectious agents (3, 4).
It produces oxygen radicals
which can damage fish gills leading to suffocation, press tv reported.
Chronic intake of potato chips in humans increases the production of reactive oxygen radicals
by leukocytes and increases plasma C-reactive protein: a pilot study.
Chemical peptizers are materials usually based on a combination of a free radical scavenger and a so-called booster material, as an effective source of oxygen radicals
that serve to increase oxidative chain scission at higher temperatures.
