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