Nitric oxide and macrophage function.

Annual Review of Immunology, 1997
At the interface between the innate and adaptive immune systems lies the high-output isoform of nitric oxide synthase (NOS2 or iNOS). This remarkable molecular machine requires at least 17 binding reactions to assemble a functional dimer.

The L-arginine-nitric oxide pathway.

New England Journal of Medicine, 1993
The discovery that mammalian cells generate nitric oxide, a gas previously considered to be merely an atmospheric pollutant, is providing important information about many biologic processes. Nitric oxide is synthesized from the amino acid L-arginine by a

Raman spectra of graphite oxide and functionalized graphene sheets.

Nano letters (Print), 2008
We investigate Raman spectra of graphite oxide and functionalized graphene sheets with epoxy and hydroxyl groups and Stone-Wales and 5-8-5 defects by first-principles calculations to interpret our experimental results.

Single-Atom Catalysts Based on the Metal-Oxide Interaction.

Chemical Reviews, 2020
Metal atoms dispersed on the oxide supports constitute a large category of single-atom catalysts. In this review, oxide supported single-atom catalysts are discussed about their synthetic procedures, characterizations, and reaction mechanism in ...

Oxidized lipoproteins and nitric oxide

Current Opinion in Lipidology, 1996
Nitric oxide has an important biological role as endothelium-derived relaxing factor, a key agent in the maintenance of normal vascular tone. It can also suppress lipoprotein oxidation, a potential anti-atherogenic property. However, in arteries subject to hypercholesterolemia or atherosclerosis, whereas nitric oxide synthesis is normal its biological ...

Oxidation on Metal Oxide Surfaces

1968
The redn. of transition metal oxides and of SnO2 + Sb2O3 by 1-butene and butadiene was investigated. A single parameter Qo, defined as the heat necessary to dissociate 0.5 O2 from the oxide, detd. the type of reaction. Starting from Q0 = 17 (MnO2) and proceeding to Q0 = 70 (SnO2), the redn. produces; CO2 -> (oxygenated products) -> butadiene ->

Oxidant signals and oxidative stress

Current Opinion in Cell Biology, 2003
Although oxidants clearly possess the capacity to behave in a random and destructive fashion, growing evidence suggests that in many instances the production of reactive oxygen species is tightly regulated and their downstream targets exquisitely specific.

Oxide-Oxide composites

2006
The need for high temperature, oxidation-resistant materials has driven research into oxide-oxide composites. These materials require a crack deflecting mechanism to prevent brittle failure; both interface coatings and porous matrices have proven successful in providing this function.
