the aim of this study was to measure the alterations in serum zinc (zn) copper (cu) and iron (fe) concentrations in patients with acute and chronic cutaneous leishmaniasis. serum zinc and copper were measured by flameless atomic absorption spectrophotometer and serum iron concentration was measured by the ferrozine method with commercial kits and assay was carried out by using an automatic anal...

We describe the intracellular distributions of nine essential elements (P, S, Cl, K, Ca, Mn, Fe, Cu, and Zn) found in cardiomyocytes imaged using synchrotron X-ray induced fluorescence. Cardiomyocytes were isolated from rat hearts, flash frozen on Si(3)N(4) windows, freeze-dried, and imaged with approximately 300 nm spatial resolution. Distinct longitudinal patterns in cardiomyocytes were most ...

The concentrations of heavy metals in 21 samples collected from surface sediments from the Qinghai section of the Yellow were investigated in order to evaluate their distribution and pollution levels. The total concentrations showed wide variations with Cu 11.86~57.02 mg/kg, Fe 17236.67~41340.00 mg/kg, Mn 431.93~877.27 mg/kg, Ni 14.58~86.11 mg/kg, Zn 67.18~149.00 mg/kg, Cr 87.84~169.70 mg/kg, P...

fifty street dust samples were collected from southern and eastern parts of tehran, the capitalof iran. samples were collected during summer under dry and stable weather conditions. total concentrationsof copper (cu), cadmium (cd), lead (pb), chromium (cr), nickel (ni), zinc (zn), iron (fe), manganese (mn)and lithium (li) were determined. ten samples were then selected for characterization, met...

Freshwater quality criteria for iron (Fe), lead (Pb), nickel (Ni), and zinc (Zn) were developed with particular reference to aquatic biota in Malaysia, and based on USEPA's guidelines. Acute toxicity tests were performed on eight different freshwater domestic species in Malaysia which were Macrobrachium lanchesteri (prawn), two fish: Poecilia reticulata and Rasbora sumatrana, Melanoides tubercu...

Anthropogenic and agricultural activities are deteriorating drinking water quality of the Siling reservoir. Spatio-temporal variations and risk assessment of select heavy metals (Zn, Cu, Mn, Fe, Cr, Cd, and Pb) were investigated in water samples. During summer Mn (37.32 μg/L), Fe (41.0 μg/L), and Cd (1.18 μg/L) concentrations were higher in the water samples, while the concentrations of Zn (86....

Graded levels of a trace mineral premix containing an organic (Bioplex) source of Cu, Fe, Mn, and Zn was evaluated with additional treatments containing organic Zn or Fe. Grower-finisher pigs were fed from 25 to 115 kg BW. The number of pigs in the experiment, the breeding/genetics of the pigs, the management, and the average age of the pigs were previously reported. The experiment was conducte...

Blood selenium and trace minerals play an important role in animal's health and production. The aims of this study were to determine selenium effect on blood glutathione peroxidase (GPX) activity, trace minerals and weight gain in lambs. Twelve female Makuei breed were studied for 63 days in groups of control, nanoselenium (NanoSe) and sodium selenite (NaSe). Mean concentrations of GPX, Cu and ...

This study was conducted to investigate the blood serum and diet levels of copper, zinc and iron in Holstein dairy cattle kept under industrial farming in Isfahan province, Iran. A total of 240 blood serum samples and 24 diet samples were collected from industrial dairy cattle farms. The Cu, Fe and Zn contents were assessed in samples using atomic absorption spectrophotometer. In serum samples,...
