hepatic and renal contents of essential trace elements provide good clues to monitor the nutritional status of grazing animals. liver and kidney samples were collected from 60 sheep and 60 goats slaughtered in zarrinshahr abattoirs and analyzed for essential trace elements. hepatic fe concentrations were significantly higher in sheep than goats. there were also higher renal and hepatic fe conce...

in order to assess the potential of copper mineralization and its associated elements in soltan meydan basaltic formation situated in the north of shahrud, the method of stream sediment and heavy mineral has been used. to achieve this aim, totally 68 samples of sediments (-80 mesh in particle size) and 6 samples of heavy minerals (-20 mesh in particle size) have been collected in an optimized n...

To investigate the impact of artisanal zinc smelting activities (AZSA) on the distribution and enrichment of trace metal(loid)s in street dust of a small city in Guizhou province, SW China, street dust samples were collected and analyzed for 10 trace metal(loid)s (Cr, Co, Ni, Cu, Zn, As, Cd, Sb, Pb, and Hg). Meanwhile, the health risks of local resident exposed to street dust were assessed. The...

Heavy metal homeostasis is maintained in plant cells by specialized transporters which compartmentalize or efflux metal ions, maintaining cytosolic concentrations within a narrow range. OsMTP1 is a member of the cation diffusion facilitator (CDF)/metal tolerance protein (MTP) family of metal cation transporters in Oryza sativa, which is closely related to Arabidopsis thaliana MTP1. Functional c...

We have previously reported that oxidative stimuli liberate Zn(2+) from metalloproteins, a phenomenon that can trigger neuronal cell death. Excessive intracellular Zn(2+) in many cell types triggers the expression of genes that encode metal binding proteins, such as metallothionein, via the activation and nuclear translocation of metal response element (MRE)-binding transcription factor-1 (MTF-...

cr(iii), co(ii), ni(ii), cu(ii) and zn(ii) salts of 2-(4-nitrophenylaminocarbonyl)benzoic acid were characterized by physical, analytical and spectroscopic studies and checked for their  in-vitro antimicrobial activity against three bacterial strains, mycobacterium smegmatis (gram +ve), escherichia coli (gram -ve), pseudomonas aeuroginosa (gram -ve) and three fungal strains, nigrospora oryzae, ...

BACKGROUND Hydrazones and their metal complexes were heavily studied due to their pharmacological applications such as antimicrobial, anticonvulsant analgesic, anti-inflammatory and anti-cancer agents. This work aims to synthesize and characterize novel complexes of VO(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Zr(4+)and Pd(2+) ions with oxalo bis(2,3-butanedione-hydrazone). Single crystals of the li...

BACKGROUND Sweet fennel (Foeniculum vulgare Mill.) is one of the precious spices. Almost all parts of fennel plant are edible. The herb is used as carminative, digestive, diuretic, cosmetic and medicine. METHODS A 0.5 g of the oven dried fennel fruit and soil samples were digested by wet-digestion method. The levels of selected elements (Ca, Mg, Fe, Mn, Cu, Cr, Co, Zn, Ni, Cd and Pb) were det...

Metal contamination in agricultural soils is of increasing concern due to food safety issues and potential health risks. Accumulation of Heavy and trace metals in vegetables occur by various sources but soil is considered the major one. Consumption of vegetables containing (heavy/trace) metals is one of the main ways in which these elements enter the human body. Once entered, heavy metals are d...

2-(pyridine-2-yl)-N-p-chlorohydrazinecarbothioamide (HCPTS) was synthesized, characterized and successfully applied for the preconcentration of Cu(II), Ni(II), Zn(II), Cd(II), Co(II), Pb(II), Fe(II), and Hg(II) in water, blood, and urine samples prior to graphite furnace atomic absorption determination (GFAAS); Hg was determined by cold vapor technique. Under the optimum experimental conditions...
