OBJECTIVE To investigate the relationship between total and segmental body fat, bone mineral density and bone mineral content in undergraduate students stratified according to nutritional status. METHODS The study included 45 male undergraduate students aged between 20 and 30 years. Total and segmental body composition, bone mineral density and bone mineral content assessments were performed ...
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,...
این تحقیق با هدف تدوین استراتژی برای مدیریت زمین شناسی و اکتشافات معدنی منطقه جنوب خاوری با مرکزیت کرمان انجام گرفته است. این مدیریت امور اکتشاف مواد معدنی و تحقیقات مرتبط با علوم زمین در جنوب شرق کشور را بر عهده دارد. این مدیریت نیاز مبرمی به شناخت نقاط ضعف و قوت و نیز فرصت ها و تهدیدهای محیط فرا روی خود داشت تا با تدوین استراتژی های مناسب بتواند نقش و وظایف خود را به خوبی اجرا نماید. روش مورد...
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...
Automatic mineral identification using evolutionary computation technology is discussed. Thin sections of mineral samples are digitally photographed using a computercontrolled rotating polarizer stage on a petrographic microscope. A suite of image processing functions is applied to the images. Filtered image data for identified mineral grains is then selected for use as training data for a gene...
Mineral supplementation programs are a point of confusion for many ranchers. Sales representatives, university researchers, and cattle buyers bark at ranchers about how important it is to keep their cattle on a mineral program. Ranchers, however, are often at a loss as to how to assess mineral deficiencies, which mineral packages they need to purchase, whether they should have a custom mineral ...
