Background &Objective: Micronutrient deficiencies are the most common nutritional disorders in the world in which iron deficiency is the most important one. This study was done for investigating the prevalence of iron deficiency and its anemia in children and their mothers in Birjand city in 2011.Materials & Methods: 143 children of 1-5 years old who referred to the health care centers of Birja...
Background: Iron overload can cause many complications and damage many organs as well as physiologic functions. Consumption of phetochemicals and flavonoids with iron chelating ability, instead of synthetic iron chelators, can be less harmful and more effective. The aim of this review is to investigate hydrophilic phytochelators in iron overload condition. Methods: In this review, the possible ...
abstract fluorescens pseudomonads can suppress soil-borne plant pathogens by employing several mechanisms such as competition for iron by means of siderophores. three indigenous strains pseudomonas fluorescens (utpf5, utpf61 and utpf76), pseudomonas aeruginosa 7nsk2 and its pyoverdin mutant, mpfm1, were used for investigation the effect of iron competition on bean damping-off suppression. the r...
iron is essential to erythrocyte oxygen transport and is a catalyst for oxidative metabolism in all cells. iron is absorbed by the duodenum and requires an acidic environment for optimal absorption. iron is found for 70% in erythrocytes, and 30% in storage, and a small amount in myoglobin and cytochromes. iron supplementation reduces anemia in breastfed infants and increases in significant dose...
background there have been very few studies evaluating the close association between excess iron and cirrhosis; however, cirrhosis could be regarded as an iron-loading disorder. objectives in this study, the goal was to show the levels of the iron content in the liver tissue in certain types of cirrhosis. patients and methods in this 7 year study (2008 - 2014), in 1000 explanted livers, the amo...
absence of nutritional knowledge is one of the most important reasons of nutritional deficiencies. the aim of this study was to evaluate knowledge, attitude and practices of women about iron deficiency anemia in yazd and orumiyeh. this cross-sectional study was performed on 298 and 242, 15-49 year- old women in yazd and orumiyeh, respectively. questionnaires were prepared to collect the partici...
The structural properties and microwave absorption capability of the iron nanoparticles and iron-carbon core-shell nanoparticles have been studied, in the present paper. The investigated nanoparticles were synthesized by hydrothermal route and by reduction of hematite nanoparticles during annealing in argon-hydrogen atmosphere. Hematite-iron phase transformation during the reduction process has...
Introduction: Industrial and environmental pollution, excessive iron supplementation and blood transfusion are among the factors that may cause iron toxicity. Therefore, it is necessary to identify the mechanisms influencing or protecting against iron toxicity. The present study aimed to investigate the protective effects of quercetin as an antioxidant on hepatotoxicity induced by iron oxide an...
To investigate trunk injection treatment effects on eliminating chlorosis disorder and improving the growth of plane trees (Platanus orientalis L.), an experiment was arranged in a factorial experiment based on a randomized complete block design at Lavark Reasrch Farm, Isfahan University of Technology, Isfahan, Iran, with three replications and four treatments. Treatments consisted of different...
background: a close relationship has been reported between level of serum iron and ischemic heart diseases which is either brought about through direct effect of serum iron on myocardial cells or as an indirect result of elevated serum lipid profile. a widespread use of iron supplements has been observed due to the high prevalence of iron deficiency anemia. yet an elevated serum lipid is strong...
