... Fibroblast growth factor 23 (FGF23) increases phosphorus excretion and decreases calcitriol (1,25(OH) 2 D) levels. FGF23 increases from early stages of renal failure. We evaluated whether strict control of phosphorus intake in renal failure prevents the increase in FGF23 and to what extent inflammation...

...-23, which might contribute to elevation of circulating FGF-23 and plasma phosphate levels. In addition to its role in phosphorus regulation, recent evidence suggests that Klotho is directly involved in regulating VSMC signalling responses. In cultured VSMCs, Klotho suppressed sodium-dependent uptake...

We studied the effect of mineral supplementation and its duration is osteoporosis by analysing the calcium and phosphorus balances of 49 treated osteoporotic patients whose median length of calcium treatment...

Diets deficient in phosphorus have been shown to preserve the renal function of uraemic rats, but the role of concomitant alterations in the intake of other nutrients caused by such diets...

..., calcium, phosphorus and nitrogen. 2. There was a highly significant correlation between total body sodium measured by activation analysis and total exchangeable sodium measured by a standard isotope-dilution technique ( r = 0·92, P < 0·001). Exchangeable sodium averaged 80·3% of total body sodium. 3...

A method of measuring changes in the total body content of calcium, phosphorus, nitrogen and sodium in rats by activation analysis in vivo is described. 2. The change in the body content of the elements has...

The phosphorus balance became more positive in one subject, less negative in two and changed from negative to positive in the other two subjects...
