Oxalate binding proteins in calcium oxalate nephrolithiasis

Urological Research, 2003
The existence of several oxalate specific binding proteins have been demonstrated in human and rat kidney. These occur in both cortical and medullary cells and are distributed mostly in the subcellular organelles. About 1/3 of the total cellular oxalate binding was localised in the inner mitochondrial membrane while the rest was in the nucleus.

Calcium oxalate in plants

Trends in Plant Science, 2001
Calcium oxalate is a common biomineral in plants, occurring as crystals of various shapes. It can be found in any tissue or organ in plants and is often formed in the vacuoles of specialized cells called crystal idioblasts. Recent work indicates that calcium oxalate formation is generally a mechanism for regulating bulk-free calcium levels in tissues ...

Calcium oxalate crystal morphology

Trends in Plant Science, 2002
Plants invest considerable resources of carbon and calcium in crystal formation, indicating that it is an important basic process in growth and development. The diversity of crystal shapes, as well as their prevalence and spatial distribution, have led to several hypotheses regarding crystal function in plants.

Oxalate transport and calcium oxalate renal stone disease

Urological Research, 1996
Hyperoxaluria is considered to play a crucial role in calcium oxalate (CaOx) renal stone disease. The amount of oxalate excreted into the urine depends on intestinal absorption, endogenous production, renal clearance and renal tubular transport. Since a primary disorder has not been found so far in most CaOx stone formers and since oxalate is freely ...

Idiopathic Calcium Oxalate Urolithiasis

Endocrinology and Metabolism Clinics of North America, 1990
Approximately 70% of patients who form metabolic stones have the idiopathic calcium oxalate urolithiasis syndrome, which is diagnosed by exclusion of other identifiable metabolic abnormalities. This article reviews the classification, risk factors, and treatment options for those patients with this syndrome.

Idiopathic Calcium Oxalate Urolithiasis and Endogenous Oxalate Production

Journal of Urology, 1996
Despite the great effort that has gone into investigating urolithiasis, this condition still persists as one of the major ailments of the urinary tract. Calcium oxalate urolithiasis is the most common form, accounting for some 60 to 80% of total stones.

Transformation of calcium oxalate hydrates

Journal of Crystal Growth, 1986
The transformation kinetics of calcium oxalate trihydrate and calcium oxalate dihydrate to the thermodynamically stable monohydrate have been studied in batch precipitation systems. A combination of size distribution measurements, optical microscopy, X-ray diffraction and thermogravimetric analysis were used to characterise the processes involved.

Calcium Oxalate Urolithiasis in Cats

Journal of Endourology, 1999
Urolithiasis has long been recognized as a cause of irritative voiding in cats. Before the late 1980s, sterile struvite was the most common urolith; today, however, 40% of feline uroliths are of calcium oxalate. This change may be partly attributable to the change to urine-acidifying, magnesium-restricted diets that were introduced to reduce the ...

Oxalate: effect on calcium absorbability

The American Journal of Clinical Nutrition, 1989
Absorption of calcium from intrinsically labeled Ca oxalate was measured in 18 normal women and compared with absorption of Ca from milk in these same subjects, both when the test substances were ingested in separate meals and when ingested together. Fractional Ca absorption from oxalate averaged 0.100 +/- 0.043 when ingested alone and 0.140 +/- 0.063 ...
