... include those associated with an increase in urinary levels of calcium, oxalate and phosphate. Under these conditions, urine concentration and supersaturation leads to calcium crystal precipitation, which may be an intratubular event or initiate within the renal interstitium. The focus of discussion...

...Caroline DEAN; Jerry KANELLOS; Hung PHAM; Maria GOMES; Adrian OATES; Phulwinder GROVER; Rosemary RYALL The bikunin peptide chain of the protease inhibitor inter-α-inhibitor (∣α∣) has been reported to be an inhibitor of calcium oxalate (CaOx) crystallization, and hence has been proposed as having...

... crystallization kinetics occur in unseeded urine when supersaturation exceeds the metastable limit and that aggregation during the initial phase of crystallization does not significantly contribute to changes in turbidity. Metastable limits of urine from healthy volunteers corresponded to a calcium oxalate...

... excretion, questioning its use in hypercalciuric stone-forming patients. In addition, calcium restriction has been previously demonstrated to induce other urinary changes which might influence the relative supersaturation of calcium oxalate. So the overall effect of calcium deprivation on the relative...

... and were separated by a 20 day washout interval. Blood and urine chemistries, including intact parathyroid hormone, calcitriol and two markers of bone resorption, were performed at the end of each study period. The stone-forming risk was assessed by calculating urine saturation with calcium oxalate (βCaOx...

The whole dialysate was used for the determination of the overall calcium and oxalate removal by dialysis. The degree of saturation with calcium oxalate mono-hydrate was estimated by a computer program...
