Electrospray tandem mass spectrometry was used to determine steady-state serum and urinary inorganic sulfate and sulfate ester kinetic profiles of nine normal men after intravenous injection of the stable isotope sodium [34S]sulfate. Sulfate ester appearance was traced by eliminating inorganic sulfate from samples, followed by hydrolysis of sulfate esters to inorganic sulfate for analysis. Whol...

[1] We consider the correlation between clouds and sulfate in order to assess the relative importance of cloud aqueous-phase production of sulfate, precipatation scavenging of sulfate, and inhibition of gas-phase sulfate production beneath clouds. Statistical analysis of observed daily cloud cover and sulfate surface concentrations in Europe and North America indicates a significant negative co...

Although its role in mammalian physiology is currently underappreciated, sulfate is an obli‐ gate nutrient for numerous cellular and metabolic processes in human growth and develop‐ ment [1].The diet provides approximately one third of sulfate requirements in adults [2], although sulfate intake can vary greatly (1.5-16mmol/day) and is dependent on the source of drinking water (negligible to >50...

The sulfate-reducing bacteria-mediated reduction process is considered to be an important mechanism affecting arsenic migration and transformation in anaerobic environments. To investigate the effect of bacteria a high-arsenic aquifer on transformation, typical Desulfovibrio vulgaris was selected for micro-cosmic experiments simulate groundwater environment with or without sulfate amendment. Fe...

single-gene disorders occur when mutation in a gene causing alteration of gene function while in multifactorial disorders, mutations occur in multiple genes, and these are usually coupled with environmental causes. in addition, in a multifactorial disorder such as diabetes, the complication is under the influence of different genes. for example, in diabetic retinopathy many genes are involved i...
