Toxicological data or PBPK models were not available for any of the threeor four-component submixtures. Toxicological data were available only for the binary mixture of carbon monoxide and methylene chloride; toxicological data on the other binary submixtures were not located. PBPK models for methylene chloride generally contain components describing the metabolism of methylene chloride to form...

We examined carbon monoxide (CO) delivery by carbon monoxide-releasing molecule 2 (CORM-2) or hemoglobin (Hb) on cellular oxygen sensing and mitochondrial respiration in bovine aortic endothelial cells (BAECs). CORM-2 reduced hypoxia-inducible factor-1α (HIF-1α) and endothelin-1 (ET-1) expression in normoxic and hypoxic cells, but while Hb alone significantly reduced HIF-1α stabilization in hyp...

Carbon monoxide (CO) was ignored by the medical research community for decades, who thought that no biological relevance could emerge from exploring the physiological effects of a gas that had earned itself a reputation over the years as a ‘silent killer’ [2] . The well-known poisoning by carbon monoxide is a result of it binding to Hemoglobin, the oxygen carrier in blood with very high affinit...

We describe recent results on the CO/C02/H20 composition of comets and compare these with models of the protoplanetary disk. We argue that the cometary observations require reactions on grain surfaces to convert CO to CO2 and also require formation between the CO and CO2 snow lines. This then requires very early mixing of cometesimals in the protoplanetary disk analogous to the mixing described...

The aims of this study were to determine in-vehicle carbon monoxide (CO) levels in major commuting modes in the Metropolitan Area of Mexico City (MAMC) and to identify the main factors affecting the variation in these CO concentrations. CO concentrations were measured inside public and private transport vehicles during the winter of 1991 in Mexico City. Measurements were taken along several com...

The work investigated the carbon monoxide (CO) concentration from anthropogenic sources in eight, different Local Council Development Authority (LCDA) in Lagos State Nigeria. The CO concentration obtained as a result of movement of cars, trucks, motorcycles, working of generators, commercial and residential activities etc., was measured using the digital carbon monoxide detector (model: DC01001...

The catalytic low-temperature oxidation of CO to CO2 with molecular oxygen is of particular industrial and ecological interest. Gas-phase reaction kinetics measurements in conjunction with first-principles calculations provide comprehensive insight into the mechanisms and energetics of the low-temperature CO combustion reaction catalyzed by small free palladium clusters Pdx + (x = 2−7). Similar...

The reductive functionalization of carbon dioxide into high value organics was accomplished via the coupling with carbon monoxide and ethylene/propylene at a zerovalent nickel species bearing the 2-((di-t-butylphosphino)methyl)pyridine ligand (PN). An initial oxidative coupling between carbon dioxide, olefin, and (PN)Ni(1,5-cyclooctadiene) afforded five-membered nickelacycle lactone species, wh...

The conversion of carbon sources such as coal and methane into liquid fuels, methanol and alkanes, the latter via the Fisher-Tropsch process, requires careful control of the H2/CO ratio in synthesis gas. 1 The control is achieved in industry by the water-gas shift reaction. (Figure 1). 2 The study of carbon monoxide dehydrogenase (CODH) enzymes is significant to the water gas shift reaction bec...
