Phosphorus recovery from wastewater by precipitation as calcium phosphate could reduce the depletion of scarce phosphate rock resources and the need for mining. This study will introduce simultaneous phosphorus recovery by precipitation of calcium phosphate granules in the anaerobic treatment of black water. The reduction of humic acids in tap water had a minor effect on the free calcium concen...

1. An experiment was conducted to test the independent and combined effects of high dietary calcium and protein concentrations on the induction of visceral gout in growing birds of a layer strain. 2. One hundred and sixty healthy birds were randomly divided into 4 groups at 35 d of age. The different groups were given 4 diets containing normal or high concentrations of dietary calcium or crude ...

Several factors have been identified as important in the pathogenesis of secondary hyperparathyroidism in end-stage renal disease, including serum calcium, phosphorus, and calcitriol. To examine the independent effects of key factors, we prospectively studied 52 new hemodialysis patients with mild secondary hyperparathyroidism (PTH, 110-670 pg/mL) treated with a standardized regimen of calcium ...

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...

It has been shown (Owen, 1948 a, b) that thyroxine increases the percentage of phosphorus in cow milk without affecting the percentages of nitrogen or calcium. Experiments were therefore planned (for preliminary reports see Chanda & Owen, 1949a, b) with the object ofpartitioning the phosphorus in the milk of cows treated with thyroxine to find out whether any particular type of phosphorus compo...

Background: Pruritus is one of the commonest frustrating manifestations in chronic renal failure. The exact cause of uremic pruritus is unknown and several factors are reported to be involved in its pathogenesis, the most important of which are abnormalities in calcium and phosphorus metabolism. Broad band UVB phototherapy plays an important role in treatment of uremic pruritus through differen...

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...

abstract: mastitis is an inflammatory reaction of the mammary tissue in response to the introduction and multiplication of pathogens and is characterized by increasing somatic cell count (scc) in milk. the main objective of present study is to assess the probable associations between somatic cell (sc) levels and calcium and phosphorus and ratio of ca/p in raw milk. milk samples were collected f...

Fibroblast growth factor (FGF) 23 inhibits calcitriol production, which could exacerbate calcium deficiency or hypocalcemia unless calcium itself modulates FGF23 in this setting. In Wistar rats with normal renal function fed a diet low in both calcium and vitamin D, the resulting hypocalcemia was associated with low FGF23 despite high parathyroid hormone (PTH) and high calcitriol levels. FGF23 ...
