Reactive nitrogen species reactivities with nitrones: theoretical and experimental studies. [PDF]

open access: yesChem Res Toxicol, 2012
Reactive nitrogen species (RNS) such as nitrogen dioxide ((•)NO(2)), peroxynitrite (ONOO(-)), and nitrosoperoxycarbonate (ONOOCO(2)(-)) are among the most damaging species present in biological systems due to their ability to cause modification of key biomolecular systems through oxidation, nitrosylation, and nitration.

Targeting reactive nitrogen species suppresses hereditary pancreatic cancer. [PDF]

open access: yesProc Natl Acad Sci U S A, 2017
Significance Germline mutations of BRCA2 associate with tissue-specific cancers, such as familial pancreatic cancer. However, it is unclear why BRCA2 mutation causes tissue-specific cancer. Here, we show that pancreas-specific reactive nitrogen species (RNS) causes oxidative damage and DNA double-strand breaks.

The Role of Nitric Oxide in Nitrogen Fixation by Legumes

open access: yesFrontiers in Plant Science, 2020
The legume-rhizobia symbiosis is an important process in agriculture because it allows the biological nitrogen fixation (BNF) which contributes to increasing the levels of nitrogen in the soil.

Blue Laser Irradiation Decreases the ATP Level in Mouse Skin and Increases the Production of Superoxide Anion and Hypochlorous Acid in Mouse Fibroblasts

open access: yesBiology, 2022
Photobiomodulation studies have reported that blue light irradiation induces the production of reactive oxygen species. We investigated the effect of blue laser (405 nm) irradiation on the ATP levels in mouse skin and determined the types of reactive ...
