Deficiency in plant-available phosphorus is considered to be a major limiting factor to food production in many agricultural soils. Mineral resources are necessary to restore soil phosphorus content. In regions where conventional fertilizers are not used due to cost limitations or to mitigate adverse environmental effects, local sources of phosphate rock are being increasingly recognized for po...

BACKGROUND Mineral elements present in lignocellulosic biomass feedstocks may accumulate in biorefinery process streams and cause technological problems, or alternatively can be reaped for value addition. A better understanding of the distribution of minerals in biomass in response to pretreatment factors is therefore important in relation to development of new biorefinery processes. The object...

This study was carried out to determine the mineral concentrations in the hair and serum of normal pregnant women and hair mineral concentrations in cases of obstetric disorders. The hair mineral concentrations were analyzed by inductively coupled plasma atomic emission spectrometry. Serum mineral concentrations were analyzed by the established method. The following results and conclusions were...

This review explores the potential adverse impact of the increasing phosphorus content in the American diet on renal, cardiovascular, and bone health of the general population. Increasingly, studies show that phosphorus intakes in excess of the nutrient needs of a healthy population may significantly disrupt the hormonal regulation of phosphate, calcium, and vitamin D, which contributes to diso...

than any of the other grass mixtures when collected in the cured stage. Since aphosphorosis did not occur during the winter blood sampling period, phosphorus accumulated during the growing period on winter and alpine ranges may influence blood phosphorus during the winter when forage phosphorus is in short supply. At this time it is not known to what degree a free-ranging animal can accumulate ...

Phosphate retention and, later, hyperphosphatemia are key contributors to chronic kidney disease (CKD)-mineral and bone disorder (MBD). Phosphate homeostatic mechanisms maintain normal phosphorus levels until late-stage CKD, because of early increases in parathyroid hormone (PTH) and fibroblast growth factor-23 (FGF-23). Increased serum phosphorus, and these other mineral abnormalities, individ...

Rigorously standardized laboratory protocols are essential for meaningful comparison of data from multiple sites. Considering that interactions of minerals with organic matrices may vary depending on the material nature, there could be peculiar demands for each material with respect to digestion procedure. Acid digestion procedures were evaluated using different nitric to perchloric acid ratios...

During the first half of infancy, bone accretion in preterm infants fed an isocaloric, proteinand mineral-enriched postdischarge formula (PDF) is higher compared with those fed term formula (TF) or humanmilk (HM). This may be related to higher protein, calcium, phosphorus, and vitamin D intakes. This study investigated serum calcium, phosphate, and 25hydroxyvitamin D [25(OH)D] in relation to bo...

mineral contents of camel meat were investigated during different periods of fattening. 12 camels (camelus dromedarius), at 12 months of age, were fattened with the same diet during six and nine month periods. feed compositions included 25% alfalfa, 25% straw and 50% concentrate (55% barley, 20% bran, 15% beet pulp, 8% cottonseed meal and 2% salt) were fed under the same conditions. completely ...
