iron (in zero-valent and oxide forms) is used to remove numerous organic and inorganic contaminants in environment. however, there are few reports, especially in nano scale, on the remediation of heavy metals contaminated soils using zero-valent iron in the literature. in this study, the effect of iron on the availability of heavy metals was evaluated in a calcareous soil spiked with cadmium, z...

geophagia characterized by, severe, anaemia, dwarfism, hypogonadism • and hepatosplenomegaly is sometimes seen in young patients (and children) in iran. 2) haematological aspects of the syndrome are those of, severe, iron defi-crency anaemia3) gastric biopsies and histological findings revealed superfi cial or atrophic gastritis showing some resemblance to those seen in pernicious anaemia. 4) h...

the purpose of this study was to determine the effects of feeding iron-deficient diet during pregnancy and lactation on maternal rats. a total number of 64 rats were divided into 4 groups (pregnant), (non pregnant), (lactating) and (non lactating) with 16 animals in each group. parameters used to evaluate the effects of dietary iron deficiency on the maternal animals were: iron contents of live...

Heme oxygenase-2 (HO-2) is a critical antioxidative stress enzyme found in endothelial cells and adventitialnerves. This enzyme in conjunction with other HOs (1 and 3) metabolize heme molecule into ferrous iron,carbon monoxide (CO), and biliverdin which is further converted to bilirubin. Both biliverdin and bilirubin arepotent antioxidants, reducing the risk of atherosclerosis...

the main purpose of this study was to examine the citation patterns of discussion sections employed by local and international article writers in esp and egp subdisciplines of applied linguistics. eighty article discussion sections were selected from well-established local and international journals in the field of applied linguistics, and they were sorted according to thompson and tribble’s (2...

As part of our work on models of the iron(III) site of Fe-containing nitrile hydratase, a designed ligand PyPSH(4) with two carboxamide and two thiolate donor groups has been synthesized. Reaction of (Et(4)N)[FeCl(4)] with the deprotonated form of the ligand in DMF affords the mononuclear iron(III) complex (Et(4)N)[Fe(III)(PyPS)] (1) in high yield. The iron(III) center is in a trigonal bipyrami...

Reaction of thionyl chloride with 2-acetyl-1- benzenesulfonylpyrrole semicarbazone (6 c) gave 4 - (1- benzenesulfonyl-2 - pyrrolyl) - 1, 2, 3 -thiadiazole (lc). Selenium dioxide oxidation of 2-acetylpyrazine semicarbazone (10) in acetic acid afforded 4- (2-pyrazinyl) - 1, 2, 3- selenadiazole (4). Reaction of thionyl chloride with compound 10 gave 4- (2-pyrazinyl) - 1, 2, 3- thiadiazole (3)....
