The objective of the present study was to determine the effect of cellulose on intestinal iron absorption in rats during recovery from iron deficiency anemia. Twenty-one-day-old male Wistar-EPM rats were fed an iron-free ration for two weeks to induce anemia. At 5 weeks of age, the rats were divided into two groups (both groups receiving 35 mg of elemental iron per kg diet): cellulose group (N ...

The combination of microbial reduction and further microbial oxidation of iron was applied to the treatment of food-processing wastewater and recovery of ammonium. Fe2+ ions were formed by ironreducing bacteria under anaerobic conditions. Ammonium was recovered by co-precipitation with negatively charged iron hydroxides produced during oxidation of Fe2+ by iron-oxidizing bacteria under microaer...

BACKGROUND Rehabilitation aids recovery from stroke in animal models, including in intracerebral hemorrhage (ICH). Sometimes, rehabilitation lessens brain damage. OBJECTIVE We tested whether rehabilitation improves recovery and reduces perihematoma neuronal death. We also evaluated whether rehabilitation influences iron toxicity and inflammation, mediators of secondary degeneration after ICH....

By applying an internal standardization, we could use a rapid coprecipitation technique using lanthanum phosphate as a coprecipitant for preconcentration of iron(III) and lead in their flame atomic absorption spectrometric determination. Indium as an internal standard was added to the initial sample solution together with lanthanum and phosphoric acid; the coprecipitation of iron(III) and lead ...

An increasing demand for natural additives has shifted the attention from synthetic to natural antioxidants. The main objective of this research work to establish the antioxidant property of different Phenotypic traits of Aegle marmelos leaf in methanol and water extracts. In the present study three different morphological traits namely Trait I, Trait II and Trait III of Aegle marmelos leaf ext...

Reactive oxygen species are produced during anaerobic exercise mostly by Fe ions released into plasma and endothelial/muscle xanthine oxidase activation that generates uric acid (UA) as the endpoint metabolite. Paradoxically, UA is considered a major antioxidant by virtue of being able to chelate pro-oxidative iron ions. This work aimed to evaluate the relationship between UA and plasma markers...

the mouteh refractory pyrite concentrates at pulp densities of 1.5%, 3%, 4.5% and 6% were treated, using thiobacillus ferrooxidans dsm 581 and the same bacteria adapted on the mouteh pyritic concentrate. compared with a non-adapted culture, use of an adapted inoculum of t. ferrooxidans increased bioleaching rate of iron by a factor of 1.940, 2.011, 1.859 and 1.559 for pulp densities 1.5%, 3%, 4...

In this paper, the characteristics and current problems associated with red mud progress of research on iron extraction from high-iron are briefly described. By adding conditioning materials to quenching tempering, tailings extracted were reconstructed by heating form molten in laboratory. A thermodynamic analysis reduction reaction during reconstruction was performed, best conditions for calci...
