Metals and minerals are used profusely in practice of Ayurveda after proper incineration by the name of Bhasma. Some metals and minerals have the potency to produce toxic effects in human being. In this paper safety and toxicity profiles of Tamra Bhasma (incinerated copper, Cu), Lauha Bhasma (incinerated iron, Fe), and Yashada Bhasma (incinerated Zinc, Zn) has been presented, which reveal no se...

BACKGROUND The aim of the present study was to determine the effects of feeding trace mineralsfortified mixed microbial culture (TMC) on ruminal fermentation, nutrient digestibility, blood electrolyte status, nitrogen balance, and trace mineral balance in sheep. METHODS Mixed microbes [0.6 % (v/w) of Enterobacter sp., Bacillus sp., Lactobacillus sp., and Saccharomyces sp.] were cultured with ...

Calcium, magnesium, copper, iron and zinc are stored in hens’ egg yolk and, except for copper, the majority of these minerals are located in egg yolk granules (Table 1). Presumably, up to 90% calcium, magnesium, iron and zinc are firmly bound in the phosvitin-lipovitellin complex of granules (GREENGARD et al., 1964; TABORSKY, 1980; TUPPER et al., 1954). As was discussed by Richards, copper ions...

Copper (Cu) deficiencies are the result of either very low levels of copper in feedstuffs or because of other factors which affect the bioavailability of dietary copper. Baker and Ammerman (1995), in reviewing dietary factors which influence the bioavailability of copper, include metal-ion interactions, chelating agents, and compounds such as ascorbic acid, sugars and starches, and some amino a...

kalchoye copper-gold deposit is located about 110 kilometers east of esfahan province and within the eocene volcano sedimentary rocks. sandy tuff and andesite lava are important members of this complex.the form of mineralization in area is vein and veinlet and quartz as the main gangue phase. the main ore minerals are chalcopyrite, chalcocite, galena and weathered minerals such as goethite, iro...

Thirty-two lambs were distributed in eight treatments under 2×2×2 factorial experiment to compare the effects of two levels of selenium (0.2 to 5 mg/kg dry matter [DM]), sulphur (0.25% and 0.37%) and copper (8 and 25 mg/kg DM) levels on selenium concentration in liver and serum of lambs. A liver biopsy was done on all animals and blood samples were collected from the jugular vein prior to the b...

Objectives The objectives of the study were to evaluate the content of copper and zinc in individual layers of tooth enamel and to analyze the relationships between the study minerals in individual layers of tooth enamel. Patients and methods Fifteen human permanent teeth were cut off every 150 μm alongside the labial surface. Acid biopsy of each layer was performed. The zinc content was dete...

INTRODUCTION Gluten-free products usually contain low amounts of protein and minerals. However, the information about their nutritional quality is limited. The objective of this study was to determine the content and release of minerals from selected gluten-free products. MATERIAL AND METHODS The content and release of Ca, Mg, Fe, Zn and Cu from selected gluten-free products was determined. T...

Flotation is, doubtless, the most important process among the various techniques used for the treatment of ore. This generalpurpose technique allows the treatment of several complex ores (lead zinc, copper zinc), sulphides (copper, lead, and zinc), oxides (hematite, quartz), oxidized minerals (malachite, cerusite) and even non-metal ores (fluorite, phosphate, coal). Due to the flotation, it is ...
