A Simple Litmus Test for Aldehyde Oxidase Metabolism of Heteroarenes [PDF]
Journal of Medicinal Chemistry, 2014 The bioavailability of aromatic azaheterocyclic drugs can be affected by the activity of aldehyde oxidase (AO). Susceptibility to AO metabolism is difficult to predict computationally and can be complicated in vivo by differences between species. Here we report the use of bis(((difluoromethyl)sulfinyl)oxy)zinc (DFMS) as a source of CF2H radical for a ...

Survey of Oxidase-Positive and -Negative Bacteria Using a Quantitative Kovacs Oxidase Test [PDF]
International Journal of Systematic Bacteriology, 1976 A manometric assay system employing ascorbate and N,N,N',N'-tetra-methyl-p-phenylenediamine (TMPD) was used to quantitate terminal oxidase activity in bacterial non-proliferating whole cells. A wide variety of physiologically diverse bacteria, all of which were grown heterotrophically, was tested by this assay.

Evaluation of Serum Diamine Oxidase as a Diagnostic Test for Histamine Intolerance [PDF]
Nutrients, 2023 Histamine intolerance (HIT) is a clinical condition caused by decreased intestinal degradation of ingested histamine, primarily due to reduced enzyme diamine oxidase (DAO) activity, leading to histamine accumulation and causing various clinical manifestations.

Use of a quantitative oxidase test for characterizing oxidative metabolism in bacteria [PDF]
Applied and Environmental Microbiology, 1976 It was possible to quantitate the terminal oxidase(s) reaction using bacterial resting-cell suspensions and demonstrate the usefulness of this reaction for taxonomic purposes. Resting-cell suspensions of physiologically diverse bacteria were examined for their capabilities of oxidizing N,N,N',N'-tetramethyl-p-phenylenediamine (TMPD) using a manometric ...

In Vitro Sugar Interference Testing With Amperometric Glucose Oxidase Sensors [PDF]
Journal of Diabetes Science and Technology, 2018 Background: Electrochemical enzymatic glucose sensors are intended to measure blood or interstitial fluid glucose concentrations. One class of these glucose sensors are continuous glucose monitors (CGMs), indicated for tracking and trending of glucose concentrations in interstitial fluid and as an adjunct to blood glucose testing.

New insights into the glucose oxidase stick test for cerebrospinal fluid rhinorrhoea [PDF]
Emergency Medicine Journal, 2005 Rhinorrhoea is a clinical sign of cerebrospinal fluid (CSF) leakage in patients with skull fracture, but can also be attributable to respiratory secretions or tears. Laboratory tests confirming the presence of CSF are not sufficiently rapid to support clinical decision making in the emergency department and may not be universally available.

Hinf-I digestion of cytochrome oxidase I region is not a diagnostic test for A. m. lamarckii [PDF]
Genetics and Molecular Biology, 2006 Restriction fragment length polymorphism of whole mitochondrial DNA or PCR amplified mtDNA regions are known to be useful in discriminating among honey bee lineages and also some individual subspecies. In this study, PCR-amplified fragments of cytochrome

GREEN TEA PHENOLS INTERFERENCE IN THE GLUCOSE OXIDASE/PEROXIDASE TEST
Journal of Food Biochemistry, 2011 Green tea extract showed false-negative results in the determination of glucose via glucose oxidase (GOD) test. This investigation was undertaken to verify and find out the precise mechanism underlying this interference by determining the reaction kinetics of production and reduction of end-point chromophore.
