The development of common bean cultivars with high technological quality that are biofortified with minerals, is required to meet the demand for food with health benefits. The objectives of this study were to evaluate whether common bean genotypes differ in terms of technological and mineral biofortification traits, to study the correlations between these characters, to analyze the genetic diss...

Plasma FGF-23 concentrations and its relationship with calcium-phosphate homeostasis were evaluated in 48 perimenopausal obese women and in 29 nonobese controls. Serum parathyroid hormone, 25-hydroxyvitamin D(3), CTX1, osteocalcin, total calcium, phosphorus, creatinine, and plasma intact FGF-23 concentrations were assessed. DXA of lumbar spine and femoral neck was performed to determine bone mi...

Dietary calcium intake and bone density In the January issue of the British Journal of Nutrition Ramsdale et al. reported their study on bone density and calcium intake in fifty-six healthy pre-menopausal women. They showed that there was a correlation between calcium intake and bone density at all three femoral sites and at the spine. In a study of young Chinese women, in whom calcium intake i...

There are over 70 known mineral inten'elationships in which an additional dietary quantity of one mineral element wilt influence absowtion or utilization of another mineral element. As the animal ages, the readiness of availability of stored mineral dements in the bone decreases. Animals do adapt to reduced dietary intake of minerals as shown for Ca by reducing fecal excretion and increasing ab...

Some abnormalities in mineral metabolism are evident even at very early stages of chronic kidney disease (CKD) and are important determinants of subsequent bone and cardiovascular disease.1,2 A decade ago, fibroblast growth factor 23 (FGF23) was recognized by a few as the protein responsible for several rare inherited and acquired syndromes of osteomalacia and rickets.3,4 Only recently have stu...

Abstract Silicate minerals constitute the main components in silicon (Si)-rich biomass, affecting phosphorus (P) adsorption and release competencies of mineral-engineered biochar; however, mechanisms underlying their differences remain largely unresolved. To examine these interactions, we investigated mineralogical compositions quantified P-adsorption capacities Al-, Fe-, Mn-, Zn-, Mg-engineere...

As long ago as 1908 it was reported' that in intestinal infantilism there was serious derangement of the mineral metabolism. A number of investigations of the calcium anid phosphorus metabolism of patients with fatty diarrhoea, both adults and children, have been made at intervals since that time. It has been consistently found that the serum calcium tended to be low, and the serum inorganic ph...

egg production is lowered, with the eggshells becoming pro gressively thinner. The serum calcium of the hen falls and there is a depletion of the calcium and phosphorus contents of the bones. Nevertheless, according to Branion, the percentage composition of the shell remains constant, showing that, as in bone formation, if the mineral is deposited, it is laid down in the normal proportion. Deob...

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...
