Contribution of Dietary Oxalate and Oxalate Precursors to Urinary Oxalate Excretion [PDF]

open access: yesNutrients, 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 ...

Determination of plasma oxalate with oxalate oxidase [PDF]

open access: yesClinica 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).

The Handling of Oxalate in the Body and the Origin of Oxalate in Calcium Oxalate Stones [PDF]

open access: yesUrologia Internationalis, 2019
Urolithiasis is one of the most common urologic diseases in industrialized societies. More than 80% of renal stones are composed of calcium oxalate, and small changes in urinary oxalate concentrations affect the risk of stone formation. Elucidation of the source of oxalate and its mechanism of transport is crucial for understanding the etiology of ...

Oxalate and Oxalate Oxidase in Malt [PDF]

open access: yesJournal of the Institute of Brewing, 2009
Barley kernels contain a single oxalate oxidase located in the embryo and aleurone. It is already present in substantial quantities in unmalted grain and increases in activity during germination. It displays a very broad pH optimum: the optimum was at pH 4.0, but the enzyme still displayed more than 50% of its activity at pH 7.

Dietary Oxalate and Calcium Oxalate Nephrolithiasis [PDF]

open access: yesJournal 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 Oxalate in Urine Using Oxalate Oxidase: Comparison with Oxalate Decarboxylase [PDF]

open access: yesClinical Chemistry and Laboratory Medicine, 1979
The oxalate content of urine is determined by means of oxalate oxidase and simple pH measurement. The enzyme specifically decarboxylates oxalate, producing two moles CO2 per mole oxalate. The CO2 diffuses into an alkaline buffer solution (Hallson, P. C. & Rose, G. A. (1974), Clin. Chim. Acta 55, 29--39) in the closed reaction vessel, and reduces the pH

Interest of the BLAST paradigm and salivary markers for the evaluation of sleepiness in drivers

open access: yesFrontiers in Neuroscience, 2022
ObjectivesSleepiness is associated with decreased cognitive abilities and remains one of the main causes of fatal road accidents. The tools currently available to assess sleepiness, such as questionnaires, are subject to intra- and inter-individual ...
