In-cell NMR allows characterizing the folding state of a protein as well as posttranslational events at molecular level, in the cellular context. Here, the initial maturation steps of human copper, zinc superoxide dismutase 1 are characterized in the E. coli cytoplasm by in-cell NMR: from the apo protein, which is partially unfolded, to the zinc binding which causes its final quaternary structu...

An extremely sensitive pulse polarographic method for the determination of zinc dimethyldithiocarbamate (an agricultural fungicide) and zinc di-n-pentyldithiocarbamate (a petroleum additive), has been developed based on the reaction of their dithiocarbamate moiety with copper(II) perchlorate in acetonitrile medium. Well defined diffusion-controlled peaks are observed at –140 mV and –130 mV (vs ...

BACKGROUND It is well known that some trace elements such as zinc and copper play a significant role in many forms of hair loss. However, the effect of zinc and copper in the pathogenesis of hair loss is still unknown. OBJECTIVE The purpose of this study is to evaluate the zinc and copper status in each of four types of hair loss. METHODS A study was carried out with 30 health controls and ...

PURPOSE To investigate the aqueous humor, lens, and serum concentrations of zinc, iron, and copper in patients with pseudoexfoliative cataract and compare with patients who have senile cataract without pseudoexfoliation. METHODS Twenty-five patients with pseudoexfoliative cataract and 25 patients with senile cataract as control group were enrolled in the study. Samples from aqueous humor, ser...

The concentrations of zinc, copper, cadmium and lead in surface water, sediments and two native snail species, Bellamya bengalensis and Melanoides tuberculata from Latipada reservoir were determined. The concentrations of cadmium and lead in surface water were higher than the WHO recommended limits for drinking water standards; where as those of zinc and copper were within the permissible limit...

this study was conducted to determine the spatial variability and mapping of available micronutrients iron, zinc, copper and manganese on 20,000 hectares of soils in south of tehran lands in order to identify deficiency, enough and toxicity areas. 196 surface soil samples (0-25cm) to a regular grid network of 1000×1000m were collected and extracted by dtpa and tea and concentrations of elements...

Background: In acute lymphoblastic leukemia (ALL) the bone marrow loses its ability in the differentiation and maturation of blood cells at different stages. Zinc and copper are important co-factors for several enzymes and play an important role in maintenance of DNA integrity. Changes in serum levels of zinc and copper have been found in lymphoproliferative disorders. In the present study, the...

Concentrations of heavy metals, pH, and particle size distribution parameters were measured in Dragica stream and Djetinja River water receiving wastewaters from copper rolling mill industry, Sevojno. The concentrations of copper, zinc, lead, and mercury were determined for water samples collected in summer 2009. It was found that Copper Rolling Mill Sevojno was the significant source of water ...

Cobb 500 broilers were fed diets that were zinc deficient (35ppm), supplemented with 70ppm zinc sulfate, or 70ppm zinc sulfate + 35ppm organic zinc (MINTREXTM Zn or zincmethionine). Half the birds were given a coccidiosis vaccine (ADVENT® coccidiosis control) at day of age, and challenged with all three species on day 24. MINTREX Zn and zinc-methionine both significantly increased intestinal br...
