The tremendous need for mineral resources rooting from the rapid population growth and economical development in china has greatly accelerated exploitation of various minerals for last two decades, as a result, a broad array of environmental problems related to human mining activities, such as air and water pollution, land resources and inhabited environment devastation generated by land subsid...
Background & Aims : Many reports show a relation between exogenous thyroxine therapies on bone mineral density but the net effects remain unclear. The aim of this study was to determine the effect of replacement dose of levothyroxine on bone mineral density in premenopausal women with primary hypothyroidism . Materials & Methods: This study included 50 women with primary hypothyroidism. P...
Body weight is positively associated with bone mineral density but the relationship between obesity and bone mineral density is unclear. Leptin and adiponectin are potential independent contributors to bone mineral density. We assessed the correlations of body composition, leptin and adiponectin with bone mineral density, and whether leptin, adiponectin and body composition determine bone miner...
The new approaches of the animal production systems make managing the mineral nutrition a challenge. Versus the excessive, trace mineral supply in intensively managed livestock, well above the physiological requirements, is the no trace mineral supplementation of organic systems, which become highly dependent on trace minerals in the soil. Nowadays, in addition to the animal health perspective,...
Previous studies have demonstrated the influence of calcium phosphate (CaP) mineral coating characteristics on cell attachment, proliferation, and differentiation. However, the wide range of mineral properties that can potentially influence cell behavior calls for an efficient platform to screen for the effects of specific mineral properties. To address this need, we have developed an efficient...
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...
