Contribution of Dietary Oxalate and Oxalate Precursors to Urinary Oxalate Excretion [PDF]
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]
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 title salt, 2C19H23FN3O3+·C2O42−{systematic name: bis-[4-(3-carboxy-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydroquinolin-7-yl)-1-ethylpiperazin-1-ium] oxalate}, crystallizes with two independent monocations (AandB) and an oxalate dianion (C) in the asymmetric unit.

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