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...

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 ...

Chondroitin sulfate is a major component of the extracellular matrix in both the central and peripheral nervous systems. Chondroitin sulfate is upregulated at injury, thus methods to promote neurite extension through chondroitin sulfate-rich matrices and synthetic scaffolds are needed. We describe the use of both chondroitin sulfate and a novel chondroitin sulfate-binding peptide to control the...

The effect of low substrate concentrations on the metabolic pathway and sulfur isotope fractionation during sulfate reduction was investigated for Archaeoglobus fulgidus strain Z. This archaeon was grown in a chemostat with sulfate concentrations between 0.3 mM and 14 mM at 80 degrees C and with lactate as the limiting substrate. During sulfate reduction, lactate was oxidized to acetate, format...

introduction: controlling parenchymal hemorrhage, especially in liver, is still one of the challenges surgeons face with when they try to save the patients’ lives despite improvements in surgical procedures. there is a research contest between the researchers in this field to introduce more effective methods. this study aimed to compare the hemostatic effect of ferric sulfate and ferric chlorid...

a split plot experiment based on complete block design with three replications was carried out to evaluate the effect of irrigation and potassium fertilizer on yield and yield components of green beans, in 2011 at ahvaz. two levels of irrigation (normal irrigation and drought) and four levels of potassium sulfate fertilizer (0, 25, 50 and 100 kg ha-1) were evaluated in this study. the results o...

PURPOSE To investigate cell surface-associated keratan sulfate on the corneal endothelium. METHODS Immunolabeling techniques were used at the light, scanning, and transmission electron microscopic level to localize keratan sulfate on the corneal endothelium. The investigation included human, bovine, and rabbit corneal endothelia. A quantitative study of the relationship between cell size and ...
