The relationship between gut microbiota and short chain fatty acids in the renal calcium oxalate stones disease

The FASEB Journal, 2020
The relationship of gut microbiota and calcium oxalate stone has been limited investigated, especially with no study of gut microbiota and short chain fatty acids (SCFAs) in nephrolithiasis. We provided Sprague Dawley rats of renal calcium oxalate stones

Determination of Oxalate in Urine Using Oxalate Oxidase: Comparison with Oxalate Decarboxylase [PDF]

Clinical 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

Sources and Geographical Origins of PM₁₀ in Metz (France) Using Oxalate as a Marker of Secondary Organic Aerosols by Positive Matrix Factorization Analysis

Atmosphere, 2019
An original source apportionment study was conducted on atmospheric particles (PM10) collected in Metz, one of the largest cities of Eastern France. A Positive matrix factorization (PMF) analysis was applied to a sampling filter-based chemical dataset ...

Metabolomic Alteration in the Mouse Distal Colonic Mucosa after Oral Gavage with Oxalobacter formigenes

Metabolites, 2020
Oxalobacter formigenes has been investigated for years due to its proposed ability to produce a secretagogue compound that initiates net intestinal oxalate secretion, thereby theoretically reducing circulating oxalate and risk of kidney stone formation ...

Dietary Oxalate Intake and Kidney Outcomes

Nutrients, 2020
Oxalate is both a plant-derived molecule and a terminal toxic metabolite with no known physiological function in humans. It is predominantly eliminated by the kidneys through glomerular filtration and tubular secretion.

Reversibilidade de fósforo não-lábil em solos submetidos à redução microbiana e química: II - extrações sucessivas do fósforo pela resina de troca aniônica Reversibility of non-labile phosphorus in soils under microbial and chemical reduction: II - successive anion exchange resin extraction of phosphorus

Revista Brasileira de Ciência do Solo, 2008
A formação de P não-lábil a partir de formas lábeis, adsorvidas aos oxihidróxidos de Fe e Al, é razão para o baixo efeito residual da fertilização fosfatada em solos tropicais.

Effect of Compost Extract Addition to Different Types of Fertilizers on Quality at Harvest and Shelf Life of Spinach

Agronomy, 2021
Spinach is rich in minerals, vitamins, phytochemicals and bioactive compounds with health-beneficial effects; however, this plant also tends to accumulate oxalates and nitrates in their leaves.

Glycinium oxalate

Acta Crystallographica Section C Crystal Structure Communications, 2001
In the title compound, C2H6NO2+.C2HO4-, the glycine molecule exists in the cationic form and the oxalic acid molecule in the mono-ionized state. The molecules aggregate into alternate columns of glycinium and semi-oxalate ions. The structure is stabilized by an extensive network of hydrogen bonds.

Field Evidence of Fe-Mediated Photochemical Degradation of Oxalate and Subsequent Sulfate Formation Observed by Single Particle Mass Spectrometry.

Environmental Science and Technology, 2020
In this work, we deployed a single particle aerosol mass spectrometer (SPAMS) at a suburban coastal site in Hong Kong from February 04 to April 17, 2013 to study individual oxalate particles and a Monitor for Aerosols and Gases in Ambient air (MARGA) to ...
