The development of a fast and novel methodology to generate carbon-11 carbon monoxide ([11 C]CO) from cyclotron-produced carbon-11 carbon dioxide ([11 C]CO2 ) mediated by a fluoride-activated disilane species is described. This methodology allows up to 74 % conversion of [11 C]CO2 to [11 C]CO using commercially available reagents, readily available laboratory equipment and mild reaction conditi...

background: knowing the pattern of carbon monoxide (co) poisoning in each region is vital for enhanced health planning. this study was designed to evaluate the epidemiologic pattern of unintentional acute co poisoning in major cities of fars province, southwest of iran.  methods: this one-year cross-sectional study was carried out on unintentional co poisoning incidents in fars province, iran, ...

[1] Atmospheric carbon monoxide (CO) is measured by the EOS Microwave Limb Sounder (MLS) on NASA’s recently-launched Aura satellite. Descent has been observed in the 2004–2005 Northern Hemisphere winter polar mesosphere and upper stratosphere. During August and September 2004 enhanced CO was observed in the upper troposphere over India and Tibet. The MLS CO measurements are described and the ra...

A carbon monoxide (CO)-intoxicated patient developed increased permeability-type pulmonary edema demonstrated by a normal capillary wedge pressure and production of protein-rich edema fluid. To investigate the effect of CO on alveolar-epithelial permeability, a radio-active labelled isotope, 51Cr-EDTA (MW 377), was instilled into the airways of rabbits. Subsequent egress of the marker from the ...

In design of anaerobic bioreactor, rate equation is commonly used. Mathematical model was developed at steady state condition, to project concentration of gaseous substrate and product in biological oxidation of carbon monoxide with water to produce hydrogen and carbon dioxide. The concept of bioconversion was based on transport of CO from gas phase to liquid phase, as the CO consumption was in...

Tetrachloromethane (CT) is transformed in biological systems via two major pathways: hydrogenolysis to trichloromethane (CF) and hydrolysis to carbon dioxide. The mechanism of hydrolysis is poorly understood. One possibility is a hydrolytic reduction of CT to formate or carbon monoxide followed by oxidation to carbon dioxide. In biological systems, formate and carbon monoxide are readily oxidiz...

Carbon monoxide (CO) has long been known for its toxicity. However, in recent decades, new applications CO as a therapeutic compound have proposed, and multiple forms of therapy since developed studied. Previous research found that role gasotransmitter promotes anti-inflammatory antioxidant effects, making it an avenue interest medicine. Such effects are possible because the Nrf2/HO1 pathway, w...

A scale-up study has been performed with three different size reactors to establish the optimum operating conditions for the hydrogen production from synthesis gas by biological water-gas shift reaction using the photosynthetic bacterium Rhodosprilliunt rubrum. Optimum medium composition and operating conditions previously determined in a bench scale 1.25 L continuous stirred tank reactor (CSTR...

UNLABELLED Tuberculosis, caused by Mycobacterium tuberculosis, remains a devastating human infectious disease, causing two million deaths annually. We previously demonstrated that M. tuberculosis induces an enzyme, heme oxygenase (HO1), that produces carbon monoxide (CO) gas and that M. tuberculosis adapts its transcriptome during CO exposure. We now demonstrate that M. tuberculosis carries a n...

The carbon monoxide transfer factor (TL,co) is the product of the two primary measurements during breath-holding, the CO transfer coefficient (Kco) and the alveolar volume (VA). Kco is essentially the rate constant for alveolar CO uptake (Krogh's kco), and in healthy subjects, increases when VA is reduced by submaximal inflation, or when pulmonary blood flow increases. Recently, new reference v...
