BACKGROUND Ferrous sulfate drops are routinely used in Iran in infants older than 6 months of age. Effect of ferrous sulfate drops in preventive or therapeutic doses on gastrointestinal mucosa of infants is not studied as yet. Upper gastrointestinal complications due to acute iron poisoning are well known in this age group. In this article, we reviewed published articles on iron deposition in u...

Cellular labeling with ferumoxides (Feridex IV) superparamagnetic iron oxide nanoparticles can be used to monitor cells in vivo by MRI. The objective of this study was to use histology and MRI to evaluate an in vivo, as opposed to in vitro, technique for labeling of mononuclear leukocytes as a means of tracking inflammatory processes in the brain. Long-Evans rats were intravenously injected wit...

A study was undertaken in order to understand the kinetics and mechanism of the chemical oxidation of N,N-diethyl-m-toluamide, an insect repellent, by sulfate radical. In this experiment, sulfate radical was generated using peroxymonosulfate with iron(II) and cobalt(II) as activator. The second-order rate constant for the reaction of the sulfate radical with N,N-diethyl-m-toluamide was found to...

The dietary iron requirement for normal growth and optimum hematological values and bioavailability was determined for channel catfish Ictalurus punctatus fingerlings using eggwhite based diets supplemented with 0,5,10,20,60, and 180-mg ironkg from iron methionine or 20, 60, and 180-mg ironkg from iron sulfate. The basal diet which contained 9.2-mg ironkg, 34% crude protein and 3.1 kcal of dige...

iron deficiency is the most common form of malnutrition in developing countries. iron containing supplements have been used effectively to solve this problem. in children, because of teeth staining after taking iron drops, parents have the idea that iron drops are the cause of tooth decay; therefore, they limit this vital supplement in their children's diet. hereby, we evaluate the histologic e...

The oxidation of ferrous iron (Fe2+) in solution using Acidithiobacillus ferrooxidans has industrial applications exclusively in the regeneration of ferric iron (Fe3+) as an oxidizing agent for the removal of hydrogen sulfide from waste gases, desulfurization of coal, leaching of non-ferrous metallic sulfides and treatment of acid mine drainage. The aim of this investigation was to increase the...

Background: Advanced oxidation processes are used to remove toxic aromatic compounds with low biodegradability, such as 2-chlorophenol. This study investigates the use of Sulfate (SO4-) and persulfate (S2O82-) radicals, as one of the advanced oxidation methods, to remove 2- chlorophenol from aquatic solutions. Materials and Methods: This experimental and pilot-scale study was carried out usi...

A dynamic mixture of iron complexes was used as a colorimetric sensor for sulfated glycosaminoglycans. The sensing ensemble was prepared by mixing [FeCl(2)(H(2)O)(4)] with dipicolylamine, the functionalized bipyridyl ligand N-(6-aminohexyl)-4'-methyl-2,2'-bipyridine-4-carboxamide, and the dye Evans Blue. Upon addition of the analytes, characteristic changes in the UV-Vis spectrum of the solutio...

STUDY OBJECTIVES To determine if coadministration of polysaccharide iron complex and slow-release ferrous sulfate alter the absorption of mycophenolic acid (MPA), and to examine the potential influence of dosing relative to mycophenolate mofetil (MMF) administration and the effect of immediate- versus sustained-release iron products on the steady-state pharmacokinetics of MPA. DESIGN Prospect...
