Hydrogen Isotope Effect on the Isomerization of Peroxynitrous Acid
Croatica Chemica Acta, 1998 The proton affinity (PA) of peroxynitrite (ONOO-) and peroxynitrous acid (ONOOH) are calculated to be 1440.5 kJ mol-1 and 749.8 kJ mol-1, respectively. Comparison with results for the nitrous, nitric and peroxynitric acid and their anions supports these estimates.

On the proton affinity of peroxynitrite and peroxynitrous acid [PDF]
Croatica chemica acta, 2001 The proton affinity (PA) of peroxynitrite (ONOO-) and peroxynitrous acid (ONOOH) are calculated to be 1440.5 kJ mol-1 and 749.8 kJ mol-1, respectively. Comparison with results for the nitrous, nitric and peroxynitric acid and their anions supports these estimates.

Second OH overtone excitation and statistical dissociation dynamics of peroxynitrous acid
The Journal of Chemical Physics, 2005 The second OH overtone transition of the trans-perp conformer of peroxynitrous acid (tp-HOONO) is identified using infrared action spectroscopy. HOONO is produced by the recombination of photolytically generated OH and NO2 radicals, and then cooled in a pulsed supersonic expansion.

H<sub>2</sub>S Is a Potential Universal Reducing Agent for Prx6-Type Peroxiredoxins. [PDF]
Adv Sci (Weinh)We report the identification of H2S as reducing agent for Prx6‐type peroxiredoxins. In contrast to common physiological reducing agents of other peroxiredoxins, HS− is small enough to access the active site of oxidized Prx6‐type enzymes in the fully‐folded protein conformation.

Antioxidant Properties of Food-Derived Lactic Acid Bacteria: A Review. [PDF]
Microb BiotechnolThe graphical abstract shows an example of the division of the mechanisms of action of lactic acid bacteria in the context of antioxidant properties. Point 1 describes the scavenging of free radicals. Point 2 describes the chelation of metal ions. Point 3 describes the accumulation of manganese and the production of antioxidant enzymes.

Coupled Antibacterial Effects of Plasma-Activated Water and Pulsed Electric Field
Frontiers in Physics, 2022 In the biomedical applications of cold plasma, the dominant biological effect is most typically attributed to the reactive oxygen and nitrogen species (RONS), while the physical effect of electric fields is sometimes overlooked. Here, we investigated the

A guide to reactive oxygen species in tumour hypoxia: measurement and therapeutic implications. [PDF]
Mol OncolHypoxia reshapes tumour redox landscapes by altering compartmental ROS production (mitochondria, NOX, ER, peroxisomes). Accurate interpretation requires oxygen‐contextualised measurement (live biosensors, chemical probes, EPR, LC–MS) and awareness of artefacts (reoxygenation, probe specificity).
