Effectiveness of iron

Zero valent iron (ZVI) nanoparticles have been considered as effective materials for environmental remediation because of their strong reducing ability, high reaction activity, and excellent absorption properties. In this study, we synthesized iron nanoparticles using an environmentally friendly method in order to treat Cr(VI) ions in an aqueous medium.

This paper aimed to determine the grey water footprint (GWF) of geothermal water resources and to investigate the effect of biochar adsorption on grey water footprint in Southeastern Turkey. In this paper, GWF has been calculated in terms of iron (Fe), arsenic (As), manganese (Mn), boron (B), and chrome (Cr) concentrations for fifteen observation geothermal resources located in Southeastern Anatolia Region. In this study, a new approach based on the GWF was developed in order to determine the geothermal water pollution.

In this paper, oxidation of red methyl (MR) - an azo in dye by UV / H2O2 was studied. The effect of solution volume and initial concentration was studied. Under optimal conditions, project a UV light through the bottom of the solution containing MR. The rate of color change is proportional to the increase of H2O2 concentration. After 50 minutes, the decolorization effect with 16 ppm H2O2 is 38%, slightly higher than the content of 14 ppm H2O2.

The beneficial influence of dietary curcumin, capsaicin and their combina-tion on the susceptibility of low-density lipoprotein (LDL) to oxidation was examined in an animal study. Individually, both dietary curcumin and capsaicin significantly inhibited thein vivo iron-induced LDL oxidation, as well as copper-induced oxidation of LDLin vitro. The protective effect of the combination of curcumin and capsaicin on LDL oxidation was greater than that of individual compounds.

Exposure of mammalian cells to oxidant stress causes early (iron catalysed) lysosomal rupture followed by apoptosis or necrosis. Enhanced intracellular production of reactive oxygen species (ROS), presumably of mitochondrial origin, is also observed when cells are exposed to nonoxidant pro-apoptotic agonists of cell death. We hypothesized that ROS generation in this latter case might promote the apoptotic cascade and could arise from effects of released lysosomal materials on mitochondria.

Intravenous iron, used for the treatment of anemia in chronic renal failure andother diseases, represents a possible source of free iron in tissue cells, particularly in the liver. In this study we examined the effect of different sources of intravenous iron (IVI) on the labile iron pool (LIP) which represents the nonferritin-bound, redox-active iron that is implicated in oxidative stress and cell injury. Furthermore, we examined the role of the LIP for the synthesis of ferritin.

Circular dichroism (CD) spectra of two major hemoglobin components (Hb), HbI and HbIV, from Oncorhyncus mykiss(formerly Salmo irideus) trout were evaluated in the range 250–600 nm. HbI is characterized by a complete insensitivity to pH changes, while HbIV presents the Root effect. Both reduced [iron(II) or oxy] and oxidized (met) forms of the two proteins were studied at different pHs, 7.8 and 6.0, to obtain information about the pH effects on the structural features of these hemoglobins.

The mitochondrial cytochromeb missense mutation, G167E, has been reported inapatientwithcardiomyopathy. The residue G167 is located in an extramembranous helix close to the hinge region of the iron–sulfur protein. In order to characterize the effects of the mutation on the structure and function of thebc1complex, we introducedG167E into the highly similar yeast cytochromeb. The mutation had a severe effect on the respiratory function, with the activity of thebc1complex decreased to a fewper cent of the wild type....

Several studies have shown that deficient uptake or excessive break down of membrane phospholipids may be associated with neurodegenerative and psychiatric disorders. The purpose of the present study was to examine the effects of postnatal iron administration in lipid composition and behavior and whether or not the established effects may be altered by subchronic administration of the neuroleptic compounds, clozapine and haloperidol.
