Toll-like Receptor 2 Is Essential for the Sensing of Oxidants during Inflammation [PDF]

American Journal of Respiratory and Critical Care Medicine, 2009
Rationale The mechanisms by which oxidants are sensed by cells and cause inflammation are not well understood. Objectives: This study aimed to determine how cells "sense" soluble oxidants and how this Is translated into an Inflammatory reaction ...

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 ...

Role of Nitric Oxide in Hydroxylamine Oxidation by Ammonia-Oxidizing Bacteria

Applied and Environmental Microbiology, 2023
Ammonia oxidation by chemolithoautotrophic ammonia-oxidizing bacteria (AOB) is thought to contribute significantly to global nitrous oxide (N 2 O) emissions and leaching of oxidized nitrogen, particularly through their activity in nitrogen (N)-fertilized agricultural production systems.

Oxide Interfaces: Theory of Oxide-Oxide and Oxide-Metal Interfaces

1987
We discuss the prediction of oxide-metal adhesion emphasising those cases where the metal does not react chemically with the oxide. Theoretically, the complications are forbidding, partly because of the chemical and morphological complexity of practical systems, and partly because there are many distinct contributions to adhesion.

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.

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 ->

The decomposition of nitrous oxide on neodymium oxide, dysprosium oxide and erbium oxide

Journal of Catalysis, 1973
Abstract The decomposition of nitrous oxide on neodymium oxide, dysprosium oxide and erbium oxide has been studied in two pressure ranges of approximately 1 to 10 Torr and 10 to 100 Torr, over a temperature range of 400 to 600 °C. In all cases, the kinetics are first-order in nitrous oxide with a pseudo-rate constant varying with initial pressure ...

Modelling oxide–oxide and oxide–metal interfaces

J. Chem. Soc., Faraday Trans., 1990
Recent years have seen a large increase in interest in interfaces of ionic and ceramic crystals and an appreciation of their importance in determining many of the properties of materials. Static-lattice calculations have made a major impact on the interpretation of the role of point defects in controlling observed behaviour in the bulk and are now ...

Polyneuropathy Due to Ethylene Oxide, Propylene Oxide, and Butylene Oxide

Environmental Research, 1993
Axonal neuropathy occurs due to occupational ethylene oxide (EtO) exposure. The experimental model of human EtO neuropathy was established. In addition, the neurotoxic effects of propylene oxide (PpO) and butylene oxide (BtO) were demonstrated in rats.
