An investigation into the unusual linkage isomerization and nitrite reduction activity of a novel tris(2-pyridyl) copper complex [PDF]
The copper-containing nitrite reductases (CuNIRs) are a class of enzymes that mediate the reduction of nitrite to nitric oxide in biological systems. Metal–ligand complexes that reproduce the salient features of the active site of CuNIRs are therefore of

Zero‐dimensional carbon nanomaterials are presented as multifunctional platforms linking structure, property, and sensing performance. Surface engineering and heteroatom doping modulate electron‐transfer and luminescent behavior, enabling electrochemical, photoluminescent, and electrochemiluminescent detection. Fundamental design principles, analytical

Nitric Oxide‐Generating Poly (allylamine hydrochloride) Coating on Biomedical Titanium Implant
We report a metal‐free, nitric oxide (NO)‐generating coating in which poly(allylamine hydrochloride) (PAH) is covalently immobilized onto titanium. The coating catalyzes NO generation from the endogenous S‐nitrosothiol GSNO, retains activity after multiple reuse cycles and pH exposures, and maintains endothelial cell viability while modulating ...

Nanozymes (NZs) have emerged as versatile artificial enzymes with tunable catalytic properties driven by atomic coordination, defect engineering, and surface chemistry. This review presents a bio–nano interface framework linking synthesis strategies, structural design, and catalytic behavior within complex biological microenvironments.

In Vitro and in Vivo Effects of Alkyl Nitrites on Methionine Synthase from Mouse Kidney and Liver
The effect of butyl and isoamyl nitrites on methionine synthase from mouse kidney and liver was investigated. A strong specific inhibition of the enzyme (50% at 7.3 x 10 4 M nitrites for kidney methionine synthase) was found.

Planktonic rotifers of a saline-lowland river : The Salado River (Argentina) [PDF]
Seasonal samples of zooplankton were taken during 1997-1999 at fifteen stations in the Salado River basin, and analysed in order to study the rotifer fauna. Spatio-temporal changes in the rotifer plankton composition were examined in the main channel and

ABSTRACT Electrochemical biosensors enable the accurate and timely detection of clinical biomarkers, improving healthcare and precision medicine. MXene nanosheets, a class of 2D transition metal carbides, nitrides, and carbonitrides, are promising materials for developing next‐generation electrochemical biosensors due to their unique physicochemical ...

We report a new thiolate‐reactive α,α‐gem‐dibromo lactam warhead that activates transcription factor Nrf2 and demonstrates anti‐inflammatory activities, which have implications in cancer, neurodegeneration, and cardiovascular diseases. RNA‐seq illuminated detailed transcriptional profiles, and chemical reactions with cysteine‐containing compounds ...
