Nitrite reduction: a ubiquitous function from a pre-aerobic past

, 2009
In eukaryotes, small amounts of nitrite confer cytoprotection against ischemia/reperfusion-related tissue damage in vivo, possibly via reduction to nitric oxide (NO) and inhibition of mitochondrial function.

Immunocytochemical Localization of Nitrite Reductase in Green Algae

Plant Physiology, 1991
The distribution of nitrite reductase (EC 1.7.7.1) in the green algae Chlamydomonas reinhardtii, Monoraphidium braunii, Chlorella fusca, and Scenedesmus obliquus was studied by immunoelectron microscopy. The labeling of ultrathin cryosections was performed with anti-nitrite reductase antibodies followed by gold-labeled goat anti-rabbit antibodies. In C.

Born early, age fast: Consequences of premature birth on chronic disease and accelerated ageing

The Journal of Physiology, EarlyView.
Abstract figure legend ELGANs are exposed to several postnatal pro‐oxidant stressors, including ambient and supplemental oxygen, mechanical ventilation, infections, hyperalimentation, excessive glucocorticoids and intermittent hypoxia. Since endogenous antioxidant defences are underdeveloped, this imbalance promotes oxidative stress and inflammation ...

The Effect of Chlorhexidine Mouthwash on Blood Pressure: A Systematic Review and Meta‐Analysis

International Journal of Dental Hygiene, Volume 24, Issue 3, Page 390-403, August 2026.
ABSTRACT Aim This study evaluated the effect of rinsing with a chlorhexidine containing mouthwash (CHX‐MW) on blood pressure (BP), as compared to rinsing with a control MW or no MW, based on (randomised) controlled trials and observational studies in humans. PROSPERO CRD42020222495.

Paramagnetic NMR studies of copper-containing nitrite reductases

Paramagnetic signals have been observed in the 1H NMR spectra of copper-containing nitrite reductases (M(r) ≃ 110 kDa), which provide a detailed fingerprint of the type 1 centres in these ...

The molecular mechanism of copper-containing nitrite reductases

, 2002
Nitrogen is an essential component of all living systems and availability is largely governed by the terrestrial nitrogen cycle. From this system, several forms of nitrogen are available for use in the synthesis of biologically relevant molecules such ...

Establishment of a Purge and Trap Continuous‐Flow Isotope Ratio Mass Spectrometer System for Analysis of Stable Nitrate Isotopes (δ15N and δ18O) in Water Samples by Ti(III) Reduction

Rapid Communications in Mass Spectrometry, Volume 40, Issue 14, 30 July 2026.
ABSTRACT Rationale Pollution of surface and shallow groundwater by nitrate (NO3−$$ {\mathrm{NO}}_3^{-} $$) is a global concern, resulting in the deterioration of drinking water quality. Stable isotopes of NO3−$$ {\mathrm{NO}}_3^{-} $$ (δ15N and δ18O) can be used to trace its sources and identify prevailing biogeochemical processes.

Targeting Temozolomide‐Resistant Glioblastoma: Therapeutic Potential of Neuronal Nitric Oxide Synthase Inhibitor

Cancer Medicine, Volume 15, Issue 7, July 2026.
ABSTRACT Background and Purpose The treatment of glioblastoma remains a major clinical challenge, largely due to intrinsic and acquired resistance to Temozolomide (TMZ). We aim to advance a novel therapeutic approach to overcome TMZ resistance in human glioblastoma by using the neuronal nitric oxide synthase inhibitor BA‐101 as both a monotherapy and ...

Crataegus oxyacantha Extract Enhances Cardiac Adaptation and Reduces Oxidative‐Inflammatory Stress in Broiler Chickens Raised at High Altitude Under Cold Stress

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Crataegus oxyacantha extract at 0.4 mL/L improved cardiac function in broilers under cold stress and high altitude by increasing nitric oxide synthase gene expression, boosting nitric oxide, reducing endothelin‐1 gene expression, and lowering oxidative‐inflammatory stress, offering a natural solution to mitigate pulmonary hypertension syndrome ...

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).
