Medical Mycology Case Reports, 2015 We present two cases of pulmonary aspergillosis in which calcium oxalate crystals in the sputum proved to be a useful diagnostic clue. In case 1, Aspergillus hyphae was not identified; however, calcium oxalate crystals were present, and chronic ...

Cementum Attachment Protein-Derived Peptides Modulate Brushite and Calcium Oxalate Crystallization In Vitro. [PDF]
J Pept SciCementum attachment protein‐derived peptides adsorb to specific crystallographic faces of brushite and calcium oxalate, blocking calcium deposition. This phosphorylation‐enhanced modulation alters crystal growth under conditions in vitro, leading to the formation of irregular brushite crystals and rosette‐like calcium oxalate morphologies.

Inhibitors of Calcium Oxalate Crystallization for the Treatment of Oxalate Nephropathies [PDF]
Advanced Science, 2020 AbstractCalcium oxalate (CaOx) crystal‐induced nephropathies comprise a range of kidney disorders, for which there are no efficient pharmacological treatments. Although CaOx crystallization inhibitors have been suggested as a therapeutic modality already decades ago, limited progress has been made in the discovery of potent molecules with efficacy in ...

Pulmonary aspergilloma with prominent oxalate deposition
Clinical Case Reports, 2022 Some Aspergillus species produce oxalic acid, which reacts with tissue calcium or blood to precipitate calcium oxalate. Oxalate crystals can induce lung and kidney damage.

Randall’s plaque as the origin of idiopathic calcium oxalate stone formation: an update
Comptes Rendus. Chimie, 2021 The majority of idiopathic calcium oxalate kidney stones form on the Randall’s plaque, a subepithelial calcium phosphate plaque at the renal papilla.

Clinical Chemistry, 1989 Abstract Studies in 24 recurrent oxalate stone-formers have shown that values for urinary calcium excretion for this group on at-home diets vary significantly (P less than 0.001) more than values for creatinine excretions. By placing stone-formers on controlled in-hospital diets and measuring their calcium excretions, we were able to ...

Molecules, 2023 The polysaccharides extracted from Aspidopterys obcordata are thought to have anti-urolithiasis activity in Drosophila kidney stones. This study aimed to assess the effects of different extraction solvents on the yield, chemical composition, and ...

HISTOCHEMICAL RECOGNITION OF CALCIUM OXALATE [PDF]
Journal of Histochemistry & Cytochemistry, 1964 Of the workers applying the von Kóssa test to calcium oxalate crystals in animal tissue, about half reported blackening in silver nitrate on exposure to light. We found that "pure" calcium oxalate crystals, produced in rats by the administration of ammonium oxalate or ethylene glycol, gave a negative von Kóssa reaction.

Loss of Ecrg4 improves calcium oxalate nephropathy.
PLoS ONE, 2022 Kidney stone is one of the most frequent urinary tract diseases, affecting 10% of the population and displaying a high recurrence rate. Kidney stones are the result of salt supersaturation, including calcium and oxalate.
