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 ...

Over 13,000 articles published since 1966 seemed to show that all of these pieces of the puzzle were important in the pathogenesis of diabetic complications, yet two things suggested that something ...

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 ...

Researchers have uncovered the exact mechanism that causes new solar cells to break down in air, paving the way for a solution. Researchers have uncovered the exact mechanism that causes new solar ...
