Homogenous catalysis of peroxynitrite conversion to nitrate by diaryl selenide: a theoretical investigation of the reaction mechanism

Frontiers in Chemistry
Quenching peroxynitrite (a reactive oxidant species) is a vital process in biological systems and environmental chemistry as it maintains redox balance and mitigates damaging effects in living cells and the environment.

Is nitrate a good biomarker of the nitric oxide status? / Este ionul nitrat un bun biomarker al producţiei endogene de monoxid de azot?

Romanian Journal of Laboratory Medicine, 2015
Determinarea concentraţiilor in vivo ale monoxidului de azot (NO) este necesară pentru identificarea condiţiilor patologice în care producţia endogenă a acestui compus este redusă sau pentru identificarea unor agenţi care pot genera in vivo acest compus.

Interconversions between RNS Revealed by Transient Voltammetry with Porphyrin‐Modified Carbon Nanopipettes in Single Living Cells

Advanced Science, EarlyView.
By using porphyrin modified conductive nanopipettes, transient voltammetry can be directly applied to reveal the dynamic and complex electrochemical reactions between the reactive nitrogen species inside the single living cells. Abstract Reactive nitrogen species (RNS) play crucial roles in cellular signaling, but their quantification is very ...

Rapid Griess assay (RGA): a chairside test for ex vivo semi-quantitative oral nitrite measurement and in vitro assessment of nitrite production by oral bacteria

Journal of Oral Microbiology
Background Nitrite (NO2−) is produced through enzymatic reduction of dietary nitrate (NO3−) by oral bacteria: a process contributing to cardiovascular – and possibly oral – health.

Amyloid Peptide Nanofibrils Promote Efficient Neurotransmitter Oxidation and Serve as Scaffolds for Melanin Production

Angewandte Chemie, EarlyView.
Short amyloid peptides can act as efficient catalysts of neurotransmitter degradation, and libraries of short peptides can be used to identify core fragments present in larger proteins that might be linked to neurodegenerative diseases. Abstract We have shown that de novo designed peptides self‐assemble in the presence of copper to create ...
