The efficacy of sodium fluoride tubes in preserving glucose was compared against a serum separator tube with gel barrier. We the fall blood levels - oxalate tube. A heparinized used as standard. 45 samples were drawn from healthy patient volunteers and distributed into different tubes. Patients on medications or chronic kidney disease excluded. Glucose estimation done by oxidase-peroxidase meth...

Abstract Background Although panicle blast is more destructive to yield loss than leaf in rice, the cloned genes that function resistance are still very limited and molecular mechanisms underlying remain largely unknown. Results In present study, we have confirmed three Oxalate oxidase ( OXO ) genes, OsOXO2 , OsOXO3 OsOXO4 from a blast-resistant cultivar BC10 rice. The expression of were induce...

Oxalate-degrading bacteria comprise a functional group of microorganisms, commonly found in the gastrointestinal tract of mammals. Oxalate is a plant secondary compound (PSC) widely produced by all major taxa of plants and as a terminal metabolite by the mammalian liver. As a toxin, oxalate can have a significant impact on the health of mammals, including humans. Mammals do not have the enzymes...

n engl j med 369;22 nejm.org november 28, 2013 2163 and its soluble salts are toxic before conversion to calcium oxalate endogenously remains unclear. Although the depiction of the metabolism of glyoxylate in Figure 1 of the article is correct, the figure does not show the generation of oxalate. The legend states that in hyperoxaluria types 1 and 2, accumulated glyoxylate is converted to oxalat...

About 75% of all kidney stones are composed primarily of calcium oxalate and hyperoxaluria is a primary risk factor for this disorder. Since absorbed dietary oxalate can make a significant contribution to urinary oxalate levels, oxalate from legumes, nuts, and different types of grain-based flours was analyzed using both enzymatic and capillary electrophoresis (CE) methods. Total oxalate varied...

Oxalate, broadly found in both dietary and endogenous sources, is a primary constituent in 80% of kidney stones, an affliction that has tripled in prevalence over the last 40 years. Oxalate-degrading bacteria within the gut microbiota can mitigate the effects of oxalate and are negatively correlated with kidney stone formation, but bacteriotherapies involving oxalate-degrading bacteria have met...

The radioenzymatic method was used to determine the oxalate contents in common Japanese foods. High concentrations of oxalate were detected in spinach, Perilla frutescens, pepper, sesame, chocolate, and tea. Beer and coffee also contained some oxalate. Fruit and meat were low in oxalate content. Therefore, among the common Japanese foods, the most important foods to be avoided to restrict oxala...

Peroxidase and hydrogen peroxide both play important roles in the final stages of the lignification pathway. Peroxidase, in the presence of H2O2 catalyses the oxidation of monolignols to give lignin. In order to examine this process we looked at lignification in transgenic tobacco plants expressing a barley peroxidase gene, HvPrx8, either alone or in combination with a wheat germin gene, g.f 2....

The recently described cupin superfamily of proteins includes the germin and germinlike proteins, of which the cereal oxalate oxidase is the best characterized. This superfamily also includes seed storage proteins, in addition to several microbial enzymes and proteins with unknown function. All these proteins are characterized by the conservation of two central motifs, usually containing two or...

Hyperoxaluria is a major risk factor for calcium oxalate kidney stones and the intestine is recognized as an important extra-renal pathway for eliminating oxalate. The membrane-bound chloride/bicarbonate (Cl(-)/) exchangers are involved in the transcellular movement of oxalate, but little is understood about how they might be regulated. , CO2, and pH are established modulators of intestinal NaC...
