Contribution of dietary oxalate to urinary oxalate excretion [PDF]

open access: yesKidney International, 2001
The amount of oxalate excreted in urine has a significant impact on calcium oxalate supersaturation and stone formation. Dietary oxalate is believed to make only a minor (10 to 20%) contribution to the amount of oxalate excreted in urine, but the validity of the experimental observations that support this conclusion can be questioned.

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 ...

Probiotic Oxalate-Degrading Bacteria: New Insight of Environmental Variables and Expression of the oxc and frc Genes on Oxalate Degradation Activity

open access: yesFoods, 2022
Oxalate, a compound produced by many edible plants and as a terminal metabolite in the liver of mammals, is a toxin that has a detrimental role to human health. Humans and other mammals do possess enzymatic systems to degrade oxalate.

Two One-Dimensional Copper-Oxalate Frameworks with the Jahn–Teller Effect: [(CH3)3NH]2[Cu(μ-C2O4)(C2O4)]·2.5H2O (I) and [(C2H5)3NH]2[Cu(μ-C2O4)(C2O4)]·H2O (II)

open access: yesMagnetochemistry, 2023
Two one-dimensional oxalate-bridged Cu(II) ammonium salts, [(CH3)3NH]2[Cu(μ-C2O4)(C2O4)]·2.5H2O (I) and [(C2H5)3NH]2[Cu(μ-C2O4)(C2O4)]·H2O (II) were obtained and characterized.

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 ...

A conserved oxalyl-coenzyme A decarboxylase in oxalate catabolism

open access: yesPlant Signaling & Behavior, 2022
The ability to biosynthesize oxalic acid can provide beneficial functions to plants; however, uncontrolled or prolonged exposure to this strong organic acid results in multiple physiological problems.

Influence of Ambient Atmospheric Environments on the Mixing State and Source of Oxalate-Containing Particles at Coastal and Suburban Sites in North China

open access: yesAtmosphere, 2022
Photodegradation is a key process impacting the lifetime of oxalate in the atmosphere, but few studies investigated this process in the field due to the complex mixing and sources of oxalate. Oxalate-containing particles were measured via single-particle

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).

Effect of Calcium Fertilization on Calcium Uptake and Its Partitioning in Citrus Trees

open access: yesAgronomy, 2023
Calcium (Ca) plays a vital role as a macronutrient in the growth and development of plants. In order of decreasing solubility, Ca can be found in vegetal tissues as soluble Ca (Fraction I), bound Ca (mainly pectates, Fraction II), inorganic insoluble Ca (
