background : the role of minerals on parasite persistency and the interaction between minerals and animal responses to the parasite infestation is not clear. for these reasons, the present re­search was aimed to compare copper, zinc and iron status in sheep with parasitic myocarditis and healthy ones in 2009. methods : blood and heart tissue samples were collected from 145 slaughtered sheep and...

copper smelting slags are hard materials. therefore,to recover their copper by flotation method, grinding should be carried out to obtain optimal particle size. copper smelting slags in the bardeskan district, with work index of 16.24 kwh/st, were grinded for 65 minutes to reach an acceptable degree of freedom for the flotation tests, with particle size of 80%, smaller than 70 μm. with this gri...

Background Copper is one of the most critical of the essential trace minerals required by animals. It is vital in the body as a component of (or cofactor for) enzyme systems involved in iron transport and metabolism, red blood cell formation and immune function. Included in almost every trace mineral premix (blended to provide mineral supplementation to animal rations) is enough copper to satis...

Twenty freshly calved healthy triple crossbred (HF x J x K) cows were divided randomly into four groups each of five animals from the day of calving to observe the effect of supplementation of minerals + proteins-vitamins (Nutri-sacc power pack, Vetcare) and enzymes (Neozyme RU, Biocon India Ltd) on service period and fortnightly plasma profile of macro-micro minerals up to 105 days postpartum....

Copper plays a key role in the physiology of methanotrophs. One way that these bacteria meet their high copper requirement is by the biosynthesis and release of high affinity copper binding compounds called methanobactins. Recent advances in methanobactin characterization include the first crystal structure, detailed spectroscopic analyses, and studies of metal ion specificity. Methanobactin ma...

In this research, copper borates are synthesized by the reaction of copper sulfate pentahydrate (CuSO4.5H2O) and tincalconite (Na2O4B7.10H2O). The experimental parameters are selected as 80C reaction temperature and 60 of reaction time. The effect of mole ratio of CuSO4.5H2O to Na2O4B7.5H2O is studied. For the identification analyses X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectr...

Chelating is the chemical process by which a mineral (iron, cobalt, copper, zinc, and manganese) is combined with a mixture of amino acids and peptides. The resulting substances are known as chelates. Another descriptive term, proteinates, refers to the amino acid bond. These chelated minerals are thought to be more digestible than nonchelated forms. In other words, chelation makes the minerals...

Phosphorus K-edge X-ray absorption near-edge structure (XANES) spectroscopy was performed on phosphate mineral specimens including (a) twelve specimens from the apatite group covering a range of compositional variation and crystallinity; (b) six non-apatite calcium-rich phosphate minerals; (c) 15 aluminium-rich phosphate minerals; (d) ten phosphate minerals rich in either reduced iron or mangan...
