Contribution of Dietary Oxalate and Oxalate Precursors to Urinary Oxalate Excretion [PDF]
Nutrients, 2020 Kidney stone disease is increasing in prevalence, and the most common stone composition is calcium oxalate. Dietary oxalate intake and endogenous production of oxalate are important in the pathophysiology of calcium oxalate stone disease. The impact of dietary oxalate intake on urinary oxalate excretion and kidney stone disease risk has been assessed ...

Oxalate Crystallization under the Action of Brown Rot Fungi
Crystals, 2023 Brown rot fungi belong to the wood-rotting fungi, which produce oxalic acid and actively decompose wood. We first found oxalates formed under the action of brown rot fungi in natural conditions on stone (Rogoselga adit, Karelia, Russia), proposed a model

Journal of Education, Health and Sport, 2018 Urolithiasis is considered a civilization disease. The prevalence is estimated at 5-20% of the population. There are many litogenesis risk factors such as hypercalciuria, hypophosphaturia, low urine pH or increased excretion of oxalates with urine - a ...

One-Pot Synthesis of Dioxime Oxalates
Molbank, 2022 Dioxime oxalates, a type of carbonyl oximes, are well-known as clean sources of iminyl radicals that undergo key organic chemistry transformations. A series of dioxime oxalates is reported in this manuscript, obtained by the reaction of the corresponding

Dietary Oxalate and Calcium Oxalate Nephrolithiasis [PDF]
Journal of Urology, 2007 Patients with calcium oxalate kidney stones are advised to decrease the consumption of foods that contain oxalate. We hypothesized that a cutback in dietary oxalate would lead to a decrease in the urinary excretion of oxalate and decreased stone recurrence. We tested the hypothesis in an animal model of calcium oxalate nephrolithiasis.Hydroxy-L-proline

Determination of plasma oxalate with oxalate oxidase [PDF]
Clinica Chimica Acta, 1984 A method for the determination of plasma oxalate using oxalate oxidase (EC 1.2.3.4) and deproteinised plasma is described. Reference values are 1.2-6.4 mumol/l (n = 24, mean +/- SD 3.3 +/- 1.5 mumol/l). The sensitivity is 6-7 nmol, the accuracy 3-5 nmol, and the coefficient of variation 10.4% (at a level of 23 nmol).
