glucuronic acid/hypoxia

The regulation of glucuronidation during hypoxia was studied in isolated hepatocytes by analysing the dependence of acetaminophen glucuronidation rate on the intracellular concentrations of UTP, glucose 1-phosphate, UDP-glucose and UDP-glucuronic acid. The steady-state concentrations of these

Heart failure is accompanied with tissue (circulatory) hypoxia, and the metabolism of several drugs has been reported to be reduced in heart failure. The aim of this study was to investigate the effect of another type of respiratory hypoxia, hypoxic hypoxia (FiO2 15 % for 24 h followed by FiO2 10 %

Azomycin glucuronate was coupled to a PnAO ligand to create azomycin-based ligands that would form water-soluble 99mTc-azomycin complexes for imaging hypoxic tissue. 1-beta-D-(2-Nitroimidazolyl)glucuronic acid, (see structure in text), was synthesized by coupling 2-nitroimidazole with

Corneas from mouse, rat and rabbit were analysed quantitatively and/or qualitatively for collagen and acid glycosaminoglycans. They were examined by light and electron microscopy, using Alcian blue and Cupromeronic blue, in critical electrolyte concentration methods, with or without digestion by

Early 2020, racehorse doping cases revolved around the hypoxia-inducible factor (HIF) activator IOX-2. While the composition of IOX-2 was known and monitored also in human doping controls since several years, the testing capability of routine sports drug testing methods was revisited concerning this

Hypoxia-inducible factor (HIF) stabilizers increase blood haemoglobin levels after oral administration and their use in sports was recently banned by the World Anti-Doping Agency. For the support of analytical assay development, the metabolic fate of two model HIF stabilizers, based on the

The purpose of this study was to evaluate the hypothesis that NADPH supply in intact cells is regulated by oxygen tension. This was accomplished by studying monooxygenation in perfused livers from Ah locus-responsive C57BL/6J mice, where rates of monooxygenation are high. Elevation of flow rate

A water-soluble polysaccharide (STPC2) was isolated from the boiling-water extract of Sargassum thunbergii, purified by CaCl2 precipitation and chromatography on DEAE-cellulose and Sephacryl S-300 column. It was found that STPC2, with a molecular weight of 57kD, was composed of fucose, xylose,

The degradable starch microspheres (DSM) used have a size of 45 microns and are dissolved by amylase in blood. After intraarterial administration of a mixture of DSM and cytostatic drugs the coinjected drugs remain for a longer time in the target tissue/tumor. A transient hypoxia occurs. Systemic

We all depend on molecular oxygen and heme for our life, as evident from the pigments in blood and daily wastes. About 80% of serum bilirubin is derived from hemoglobin of senescent erythrocytes, which have finished their mission of 120 days and have been phagocytized by macrophages in the
