environmental effects of gol-e-gohar iron ore mine on groundwater of the area
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
A lipophilic iron chelator can replace transferrin as a stimulator of cell proliferation and differentiation
Of the different growth supplements used in chemically defined media, only transferrin is required for differentiation of tubules in the embryonic mouse metanephros. Since transferrin is an iron-carrying protein, we asked whether iron is crucial for tubulogenesis. Differentiation of metanephric tubules both in whole embryonic kidneys and in a transfilter system was studied. The tissues were gro...
متن کاملIron bound to the lipophilic iron chelator, 8-hydroxyquinoline, causes DNA strand breakage in cultured lung cells.
The formation of DNA-strand breaks was studied in cultured human lung cells (A 549) subjected to iron, either in the form of iron(III) citrate or in combination with the metal chelators ethylene diamine tetra-acetic acid (EDTA), nitrilo triacetic acid (NTA), or 8-hydroxyquinoline (8HQ). After 15 min exposure to 5 microM iron(III) citrate or iron chelate, the cellular levels of iron were found t...
متن کاملEfficacy and Possible Adverse Effects of the Oral Iron Chelator
Eleven patients with p thalassemia major were entered into the trial of the oral chelator 1.2-dimethyl-3-hydroxypyrid-4one (L1). Their ages ranged from 17 to 26 years (mean & SD, 22.3 & 2.7). Six were male and five were female. L1 was administered at an initial daily dose of 42.5 to 60 mg/kg as a single dose. After 4 weeks, the dose was increased to 85 to 119 (102 f 10.7) mg/kg for 191 to 352 d...
متن کاملCytotoxic analogs of the iron(III) chelator pyridoxal isonicotinoyl hydrazone: effects of complexation with copper(II), gallium(III), and iron (III) on their antiproliferative activities.
This study examined if complexation with metals increased the antiproliferative activities of chelators of the pyridoxal isonicotinoyl hydrazone (PIH) class. Addition of iron(III) to some PIH analogs markedly depressed their activities, whereas it had little effect on others. The gallium(III) complex of PIH, but not its copper(II) complex, was more efficient than the apochelator at inhibiting [...
