Accidental Alkyl Nitrite (Poppers) Ingestion in a 37‐Year‐Old Patient: A Case Report

Clinical Case Reports, Volume 13, Issue 5, May 2025.
ABSTRACT This case demonstrates severe methemoglobinemia in a male patient following accidental ingestion of alkyl nitrites (“Poppers”). Prompt recognition and treatment with methylene blue ensured rapid recovery. Clinicians must consider this condition in patients with unexplained cyanosis and discordant oxygen saturation.

Importance of the two dissimilatory (Nar) nitrate reductases in the growth and nitrate reduction of the methylotrophic marine bacterium Methylophaga nitratireducenticrescens JAM1

Frontiers in Microbiology, 2015
Methylophaga nitratireducenticrescens JAM1 is the only reported Methylophaga species capable of growing under anaerobic conditions with nitrate as electron acceptor.

Enhancing Crop Nutrition in Arid and Semiarid Regions of Africa Through Genome Editing Using CRISPR/Cas

Food and Energy Security, Volume 14, Issue 3, May/June 2025.
ABSTRACT Food insecurity is a pressing issue in Africa, aggravated by escalating drought, jeopardizing the region's ability to meet nutritional requirements for human health. In arid and semiarid regions, crop yield is severely affected by drought and salinity.

Catalytically important damage-free structures of a copper nitrite reductase obtained by femtosecond X-ray laser and room-temperature neutron crystallography

IUCrJ, 2019
Copper-containing nitrite reductases (CuNiRs) that convert NO2− to NO via a CuCAT–His–Cys–CuET proton-coupled redox system are of central importance in nitrogen-based energy metabolism.

The regulation of glutamate dehydrogenase, nitrite reductase, and nitrate reductase in excised pea roots by nitrite

Biologia Plantarum, 1973
Both nitrite reductase and nitrate reductase were induced by nitrite, but there were differences in the time course of induction and in the response to different NO2 - concentrations between these enzymes. NH4 + depressed the induction of nitrite reductase. NADH2 dependent glutamate dehydrogenase activity was enhanced by those NO2-concentrations in the

The Cells of the Vasculature: Advances in the Regulation of Vascular Tone in the Brain and Periphery

Basic &Clinical Pharmacology &Toxicology, Volume 136, Issue 5, May 2025.
ABSTRACT The vasculature is a complex tissue in which multiple cell types coordinate the regulation of tissue perfusion in response to hemodynamic and biochemical signals. Advances in this field are continuing to deepen our understanding of the relative importance of these cell types through the body.

Identification of iron(III) peroxo species in the active site of the superoxide reductase SOR from Desulfoarculus baarsii [PDF]

Journal of the American Chemical Society, American Chemical Society, 2002, pp.4966-7, 2015
The active site of superoxide reductase SOR consists of an Fe2+ center in an unusual [His4 Cys1] square-pyramidal geometry. It specifically reduces superoxide to produce H2O2. Here, we have reacted the SOR from Desulfoarculus baarsii directly with H2O2.

Effect of tungsten on nitrate and nitrite reductases in Azospirillum brasilense Sp7

, 1991
Tungstate, at concentrations that completely suppressed nitrate reductase activity in Paracoccus denitrificans, caused only partial inhibition of nitrate reductase in Azospirillum brasilense Sp7.
