Oxidative stress and endoplasmic stress in calcium oxalate stone disease: the chicken or the egg?
Free radical research, 2020Crystal modulators play a significant role in the formation of calcium oxalate stone disease. When renal cells are subjected to oxalate stress, the loss in cell integrity leads to exposure of multiple proteins that assist and/or inhibit crystal ...

To investigate potential oxalate‐degrading bacteria, including Oxalobacter formigenes, Lactobacillus (Lac) and Bifidobacterium (Bif) genera, and Oxalyl‐CoA decarboxylase (oxc) encoding Lac (LX) and Bif (BX) species in participants with recurrent calcium ...

Journal of Urology, 1976
Calcium oxalate crystals were obtained from urine specimens submitted to a hospital laboratory. The incidence of crystalluria was 4.2 per cent of 42 times the maximum reported incidence of urinary calculi. In our opinion the crystalluria was real and not artifactual.

Transformation of calcium oxalate hydrates
Journal of Crystal Growth, 1986The 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: calcium phosphate transformations
Urological Research, 2010Knowledge of the physical-chemical mechanisms responsible for the crystal growth and dissolution events involved in stone formation might enable the manipulation of thermodynamics in such a way as to increase the solubility of sparingly soluble phases (such as calcium oxalates and phosphates), thereby reducing the driving force for stone formation ...

Oxalate binding proteins in calcium oxalate nephrolithiasis
Urological Research, 2003The 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.

Journal of the American Dietetic Association, 1993
Dietary restriction of oxalate intake has been used as therapy to reduce the risk of recurrence of calcium oxalate kidney stones. Although urinary oxalate is derived predominantly from endogenous synthesis, it may also be affected by dietary intake of oxalate and calcium.

Urinary oxalate and calcium excretion by dogs and cats diagnosed with calcium oxalate urolithiasis
Veterinary Record, 2012Urine concentrations of oxalate and calcium play an important role in calcium oxalate (CaOx) urolith formation in dogs and cats, with high excretions of both substances increasing the chance of CaOx urolithiasis. In 17 CaOx-forming dogs, urine calcium:creatinine ratio (Ca:Cr) was found to be increased compared with healthy control dogs, whereas urine ...

Calcium Oxalate Crystals in the Aqueous
American Journal of Ophthalmology, 1979We found octohedral crystals in the aqueous of a patient with phacolytic glaucoma. They were identified as calcium oxalate by their physical and chemical characteristics.

Understanding the Role of Citric Acid on the Crystallization Pathways of Calcium Oxalate Hydrates
Crystal Growth & Design, 2019The precipitation of calcium oxalate can be either grown into structural support in plants or precipitated as stones in human kidneys. Previously, citrate, an effective inhibitor for oxalate stone formation, was suggested to alter the crystallization ...
