Nitrogen dioxide and carbonate radical anion: two emerging radicals in biology.
Nitrogen dioxide and carbonate radical anion have received sporadic attention thus far from biological investigators. However, accumulating data on the biochemical reactions of nitric oxide and itsExpand

Reactions of yeast thioredoxin peroxidases I and II with hydrogen peroxide and peroxynitrite: rate constants by competitive kinetics.
Peroxiredoxins are receiving increasing attention as defenders against oxidative damage and sensors of hydrogen peroxide-mediated signaling events. Likely to be critical for both functions is a rapidExpand

Uric acid oxidation by peroxynitrite: multiple reactions, free radical formation, and amplification of lipid oxidation.
Uric acid has been considered to be an efficient scavenger of peroxynitrite but the reaction between urate and peroxynitrite has been only partially characterized. Also, previous studies haveExpand

Direct EPR Detection of the Carbonate Radical Anion Produced from Peroxynitrite and Carbon Dioxide*
The biological effects of peroxynitrite have been recently considered to be largely dependent on its reaction with carbon dioxide, which is present in high concentrations in intra- and extracellularExpand

Even free radicals should follow some rules: a guide to free radical research terminology and methodology.
Free radicals and oxidants are now implicated in physiological responses and in several diseases. Given the wide range of expertise of free radical researchers, application of the greaterExpand

Reduction of 1-Cys peroxiredoxins by ascorbate changes the thiol-specific antioxidant paradigm, revealing another function of vitamin C
Peroxiredoxins (Prx) are widely distributed peroxidases that can be divided into 1-Cys and 2-Cys Prx groups based on the number of conserved cysteine residues that participate in their catalyticalExpand

Vascular oxidant stress early after balloon injury: evidence for increased NAD(P)H oxidoreductase activity.
Available evidence for oxidative stress after angioplasty is indirect or ambiguous. We sought to characterize the pattern, time course, and possible sources of free radical generation early afterExpand

Nitrite as the major source of nitric oxide production by Arabidopsis thaliana in response to Pseudomonas syringae
The origin of nitric oxide (.NO) in plants is unclear and an .NO synthase (NOS)‐like enzyme and nitrate reductase (NR) are claimed as potential sources. Here we used wild‐type and NR‐defective doubleExpand

The carbonate radical and related oxidants derived from bicarbonate buffer
The unequivocal demonstration that the carbonate radical (CO3 •‐) is produced from the reaction between the ubiquitous carbon dioxide and peroxynitrite, renewed the interest in the pathogenic rolesExpand

Connecting the chemical and biological properties of nitric oxide.
Nitric oxide (NO(•); nitrogen monoxide) is known to be a critical regulator of cell and tissue function through mechanisms that utilize its unique physicochemical properties as a small and unchargedExpand
