Amorphous biogenic calcium oxalate

ChemistrySelect, 2016
Transition from an amorphous to a crystalline phase and stabilization of amorphous phases is a common strategy in biomineralization. Although no such phenomenon has yet been reported for biogenic calcium oxalate systems, it was recently demonstrated for synthetic calcium oxalate monohydrate (COM).

Reactive oxygen species, inflammation and calcium oxalate nephrolithiasis

Translational Andrology and Urology, 2014
Calcium oxalate (CaOx) kidney stones are formed attached to Randall’s plaques (RPs) or Randall’s plugs. Mechanisms involved in the formation and growth are poorly understood.

Calcium oxalate crystalluria in a goat

Journal of the American Veterinary Medical Association, 1999
Recognition of the diverse shapes of various urine crystals is necessary for their accurate identification. Calcium oxalate dihydrate crystals most commonly have an octahedral or envelope shape. Calcium ions and oxalic acid may form calcium oxalate crystals in urine. Calcium oxalate dihydrate crystalluria is a risk factor for urolith formation.

Specificity of growth inhibitors and their cooperative effects in calcium oxalate monohydrate crystallization.

Journal of the American Chemical Society, 2014
The molecular recognition and interactions governing site-specific adsorption of growth inhibitors on crystal surfaces can be tailored in order to control the anisotropic growth rates and physical properties of crystalline materials. Here we examine this

Calcium oxalate stone and gout

Urological Research, 2009
Gout is well known to be produced by increased uric acid level in blood. The objective of this paper is to assess the relationship between gout and calcium oxalate stone formation in the humans. 48 patients with combination of gout and calcium oxalate stone problem were included.

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 ...

Natural promoters of calcium oxalate monohydrate crystallization.

Journal of the American Chemical Society, 2014
Crystallization is often facilitated by modifiers that interact with specific crystal surfaces and mediate the anisotropic rate of growth. Natural and synthetic modifiers tend to function as growth inhibitors that hinder solute attachment and impede the ...

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.

Stable amorphous calcium oxalate: synthesis and potential intermediate in biomineralization.

Chemical Communications, 2014
Amorphous calcium oxalate nanoparticles with sizes of ≈10 nm were synthesized at room temperature by hydrolysis of dimethyl oxalate from ethanolic solution.
