The pathophysiologic relevance of altered eicosanoid metabolism and free-radical production during endotoxemia is reviewed. A direct or complement-mediated release of eicosanoids - depending on the ...

The formation of superoxide ion radicals (${\mathrm{O}}_{\dot{2}}^{-}$) by chloroplasts from senescing leaves of Phaseolus vulgaris L. was determined by electron-spin-resonance measurements of Tiron ...

The HE-radical intermediate formed in the assay does not react with oxygen (aromatic aminyl radicals are not reactive toward molecular oxygen). Therefore, unlike assays with other probes (lucigenin, 2 ...

An international team of scientists including the Lomonosov Moscow State University researcher showed under which conditions a body produces more superoxide -- a dangerous form of oxygen, able to ...

According to a study published in Water Research in April 2020, superoxide produces hydroxyl radicals in lake water. Hydroxyl radicals break down poorly biodegradable organic matter such as humic ...
