background: minerals are essential materials in animal reproduction. the determination of these elements is valuable in relation to different conditions in arabian horses. objectives: the purpose of this study was to evaluate the effects of pregnancy on certain macro and micro minerals in arabian horses. methods: blood samples were collected from one hundred apparently healthy mares from differ...

Abstract A deficiency of the essential macronutrient sulfur leads to stunted plant growth and yield loss; however, an association with a symbiotic fungus can greatly improve nutrient uptake by host plant. Here, we identified functionally characterized high-affinity sulfate transporter from endophytic Serendipita indica. SiSulT fulfills all criteria expected functional responding limitation: exp...

Tetrachloroethene (PCE) dehalorespiration was investigated in a continuous coculture of the sulfate-reducing bacterium Desulfovibrio fructosivorans and the dehalorespiring Desulfitobacterium frappieri TCE1 at different sulfate concentrations and in the absence of sulfate. Fructose (2.5 mM) was the single electron donor, which could be used only by the sulfate reducer. With 2.5 mM sulfate, the d...

Introduction:Jaundice is considered as a common clinical condition during infancy. Prevention of severe hyperbilirubinemia (jaundice) is safer and easier than current therapies, like phototherapy or blood exchange. In some animal studies, zinc was found effective in reducing jaundice. In this study we evaluated the effect of zinc sulfate on neonatal hyperbilirubinemia. Materials and Methods: Th...

Sulfate ions did not inhibit methanogenesis in estuarine sediments supplemented with methanol, trimethylamine, or methionine. However, sulfate greatly retarded methanogenesis when hydrogen or acetate was the substrate. Sulfate reduction was stimulated by acetate, hydrogen, and acetate plus hydrogen, but not by methanol or trimethylamine. These results indicate that sulfate-reducing bacteria wil...
