BACKGROUND A patient with cystic fibrosis (CF) and repeated calcium oxalate renal stones prompted us to investigate other children for risk factors for this recognised complication of CF. METHODS Twenty four hour urinary excretion of calcium, oxalate, and glycolate was measured in children with CF and no symptoms of renal tract stones. Normal diet and treatments were continued. RESULTS In 2...

Glycidate (2,3-epoxypropionate) increased CO(2) photoassimilation in intact spinach (Spinacia oleracea L.) chloroplasts in the presence of various inhibitors of photosynthesis, including O(2), arsenite, azide, iodo-acetamide, and carbonylcyanide 3-chlorophenylhydrazone. Although the mechanism by which glycidate enhances photosynthesis is obscure, the stimulatory effect cannot be ascribed to eit...

A phosphatase specific for P-glycolate5 was purified from extracts of tobacco leaves until no other phosphatase activity could be demonstrated in the preparation (10). Other plants have now been examined for the presence of this phosphatase. A new isolation procedure for the enzyme was developed because the (NH4) 2SO4 fractionation procedure, which was used with tobacco leaf extracts, inactivat...

Photosynthetic carbon metabolism is rate limiting in C3 plants because of a competing process: photorespiration. Photorespiration lowers the energy efficiency of photosynthesis by metabolizing glycolate produced by the oxygenate activity of Rubisco. The chloroplasts of Arabidopsis thaliana have recently been reported to contain a novel respiratory pathway that converts glycolate directly to gly...

The isotope effects of neodymium in Nd-glycolate ligand exchange system were studied by using ion exchange chromatography. The separation coefficients of neodymium isotopes, ε's, were calculated from the observed isotopic ratios at the front and rear boundaries of the neodymium adsorption band. The values of separation coefficients of neodymium isotopes, ε's, for the Nd-glycolate ligand exchang...

Increasing levels of CO(2) have been shown to stimulate the rate of photosynthesis, eliminate the oxygen inhibition of photosynthesis (Warburg effect), and decrease glycolate formation in isolated spinach chloroplasts. Ribose 5-phosphate and fructose 1,6-diphosphate at concentrations of 5 to 10 mum also stimulate the rate of plastid photosynthesis and eliminate the Warburg effect. In contrast t...

The present work was aimed at formulation development, evaluation and comparative study of the effects of superdisintegrants in Cefixime 50 mg oral disintegrating tablets. The superdisintegrants used for the present study were sodium starch glycolate and crosscarmellose sodium. The formulated tablets were evaluated for various tableting properties, like hardness, thickness, friability, weight v...

In the title organic-inorganic hybrid compound, (C(4)H(10)NO)(3)[H(6)CrMo(6)O(24)]·4H(2)O, the Anderson-type [H(6)CrMo(6)O(24)](3-) polyoxoanion is centrosymmetric, with the Cr(III) ion lying on an inversion center. One of the two crystallographiclly independent morpholinium cations is half-occupied. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link the cations, polyoxoanions and uncoordinate...

Mildly disrupted cells of Chlamydomonas reinhardi Dangeard were incubated in a reaction medium containing glycolate, ferricyanide, and cupric ions, and then processed for electron microscopy. As a result of the cytochemical treatment, an electron opaque product was deposited specifically in the outer compartment of mitochondria; other cellular components, including microbodies, did not accumula...
