[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...

iron oxide is an important biological agent that has a key role in medical processes; however, the mechanism whereby it provides iron for human and animal cells and its biological uses remains unclear. we aimed to evaluate the effects of oral iron oxide on serum iron status and compare the results with those of iron sulfate as a reference salt. fifteen adult rabbits were divided into 3 groups o...

cefquinome sulfate (cs) is a fourth-generation cephalosporin, which has been developed solely for veterinary use. it shows potent antibacterial activity against a broad spectrum of bacterial species. however, cefquinome is susceptible to hydrolysis, which limiting its clinical employment efficacies to some extent. so, in this study, to increase cefquinome sulfate biological half-life, a novel c...

though intravenous (iv) magnesium sulphate (mgs04) has additive effect to beta-2 agonists, its additive benefit in face of combination therapy with beta-2-agonists and ipratropium (standard therapy of severe acute exacerbation of asthma) remains unaddressed. the aim of this investigation was to evaluate the role of iv mgso4 when used as an adjunct to standard therapy of severe exacerbations of ...

objectives: the aims of this study were to test whether lightening of the overexposed radiographs improve determination of endodontic files length and whether lightened radiographs are comparable with ideally exposed radiographs. material and methods: four dried human skull coated with soft tissue-equivalent wax used for exposing radiographs of the upper molars. first, the endodontic file was p...

the effect of colistin sulfate on reducing salmonella enteritidis (s.enteritidis) infection in broilers and contamination from broiler carcasses was evaluated. 40000 birds in two separate houses were considered. colistin sulfate was added in to the feed of the test group as 100g containing 1,200,000iu/ton of feed for the whole period (56 days). to isolate s.enteritidis, samples were taken from ...

the anionic surfactant sodium dodecyl sulfate (sds) was degraded by novel strain ofpseudomonas aeruginosa kgs under accession no. jq328193, which was isolated from carwash wastewater. the purpose of this research was to study different optimization conditionsrequired for enhancing the biodegradation of sodium dodecyl sulfate p. aeruginosa kgs.influence of different physicochemical factors such ...
