Background: the supplementation of natural antioxidants such plant flavonoids may counteract the deleterious actions of gamma-irradiation and iron overload. Material and Methods: the protective effect of naringin (NIN) against kidney injury induced by γ-irradiation (IRR) (6.5 Gy) and/or iron dextran (ID) (50 mg/kg. b. w) has been studied in rats given 80 mg/kg b.w of NIN for 14 days before, and...
Iron oxide (Fe2O3) is widely used as a catalyst, pigment and gas sensitive material. In this article, α-Fe2O3 nano-rods were first synthesized via a simple chemical method using iron(III) nitrate 9- hydrate (Fe(NO3)3.9H2O) as precursor. XRD pattern showed that the iron oxide nanoparticles exhibited alpha-Fe2O3 (hematite) structure in nanocrystals. The single-phase α- Fe2O3 nano-rods were prepa...
abstract this study examined the relationship between noticing pronunciation and the improvement pronunciation by administering a 50 item story, as proficiency- test in order to investigate the effectiveness of noticing pronunciation on the improvement of pronunciation. accordingly 60 qualified students were selected and assigned to the two groups of experimental and control randomly, each gr...
aimed at reducing the consumption of chemical fertilizers on crop production and according to important role of micro-nutrients such as iron, on increase performance of these products, nanocomposites effect of iron on yield and yield components of wax bean genotypes inoculated with rhizobium bacteria during experimental factorial randomized complete block design with three replications was cond...
background: the most common metal used in the body is iron and since it may produce ros, it could potentially be a dangerous substance. objectives: regarding the side effects of nanomaterials such as nano iron particles and possibility of environmental contamination including air pollution with nanoscale iron particle, this study was designed to compare the effects of conventional iron oxide wi...

BACKGROUND Asymptomatic Plasmodium spp. infections and anemia are highly prevalent conditions in tropical regions. We studied whether asymptomatic parasitemia induces hepcidin- and/or cytokine-mediated iron maldistribution and anemia. DESIGN AND METHODS A group of 1197 Indonesian schoolchildren, aged 5-15 years, were screened by microscopy for the presence of parasitemia. Concentrations of he...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
Background and Objectives: Many industrial effluent plants contain amounts of hard biodegradable compounds such as β-naphthol which can be removed by conventional treatment systems. The objective of this research is to treat wastewater containing naphthalene by nano titanium oxide coated on activated carbon. Materials and Methods: Photocatalytic experiments were carried out for different conce...
An examination of the content of arsenic, nickel, copper, selenium, zinc, and iron in the serum of 78 patients with carcinoma of the larynx was carried out. The patients were divided into 4 groups: I - patients before treatment, II - patients after surgical treatment, III - patients after radiotherapy, IV - patients after combined treatment (surgery treatment + radiotherapy). The control group ...
