The role of calcium and phosphorus in animal nutrition has received much attention in recent years, and many studies have been made to determine the need of these minerals in the nutrition of the pig. Much of the work has dealt with deficient rations and means of correcting the deficiencies. Recently the individual minimum requirements of these minerals have received the attention of investigat...

Background The increase in body weight is a serious global public health problem, with high risk of associated diseases such as diabetes, cardiovascular disease, hypertension, and some forms of cancer. The option for foods with high energy value but poor in micronutrients increases the nutritional status and contributes to the deficiency of important minerals in human health. The use of mineral...

Materials and Methods Bone mineral content was commonly used as an indicator of mineral adequacy diets of poultry [1]. The major minerals that form the inorganic matrix of bone are calcium and phosphorus [2]. The extent of bone mineralization affects bone strength [2] and poor mineralization leads to increased risk of fractures [3]. Skeletal abnormalities and architectural deterioration of bone...

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...

probes has provided a tool for investigating the chemistry of the interstitial space. It has provided data which have expanded the understanding of both physiological and pathological conditions. Under a contract with NASA, we developed ultrafiltration probes which could be implanted in bone, muscle and subcutaneous tissue to sample the interstitial fluid. In this project, sheep were used as th...

BACKGROUND Several previous epidemiological studies have shown a relation between drinking water quality and death in cardiovascular disease whereas others have not found such a relationship. An intervention study was undertaken to evaluate the effect of water with added magnesium and natural mineral water on blood pressure. METHODS A group of 70 subjects with borderline hypertension was recr...

Minerals and trace elements in cow's milk occur as inorganic ions and salts or form complexes with proteins and peptides, carbohydrates, fats and small molecules. The main mineral binder or chelators of calcium are the caseins, alphas1-casein, alphas2-casein, beta-casein and kappa-casein, but also whey proteins and lactoferrin bind specific minerals like calcium, magnesium, zinc, iron, sodium a...

Underground coal gasification (UCG) is a promising option for the recovery of low-rank and inaccessible coal resources. Detailed mineralogical information is essential to understand underground reaction conditions far from the surface and optimize the operation parameters during the UCG process. It is also significant in identifying the environmental effects of UCG residue. In this paper, with ...
