Inhibition of Glucose Oxidase Paper Tests by Reducing Metabolites

Diabetes, 1970
A negative urinary glucose oxidase test in the presence of glucbsuria may occur in patients with alcaptonuria or the carcinoid syndrome. It may also be noted after ingestion of aspirin or L-dopa. The responsible agents are potent reducing metabolites such as gentisic acid, homogentisic acid, or 5-hydroxyindole acetic acid.

A one-minute oxidase test to detect Vibrio strains isolated from cultures on thiosulphate-citrate-bile salts-sucrose (TCBS) medium.

Journal of Applied Bacteriology, 1992
Vibrio cholerae is oxidase positive, a primary characteristic used to differentiate it from Enterobacteriaceae. But false negative oxidase test results have been obtained with colonies from thiosulphate-citrate-bile salts-sucrose (TCBS) agar medium.

CSF rhinorrhoea: significance of the glucose oxidase strip test

Injury, 1987
Many authoritative medical textbooks recommended use of glucose oxidase reagent strips to distinguish cerebrospinal fluid rhinorrhoea from clear nasal discharge following head injury. A study of 50 subjects with clear nasal and lacrimal secretions, demonstrated a large proportion of positive results for glucose (44 per cent).

Evaluation of seven commercial oxidase test products with Pasteurella

American Journal of Veterinary Research, 1982
SUMMARY Seven commercial oxidase reagents were tested with 50 isolates each of Pasteurella multocida and P haemolytica. Each group of organisms consisted of a variety of serotypes from many locations and animal sources. Pasteurella multocida and P haemolytica were expected to be 90% oxidase-positive; however, only 2 commercial reagents were positive ...

QUALITY CONTROL OF MILK PRODUCTION BY MEANS OF THE CYTOCHROME OXIDASE TEST

, 1968
The test for determination of organisms which are oxidase-positive applied to raw milk samples is an effective means for indication of proper cleaning and sanitary procedures on the farm.

Glucose oxidase-mediated gelation: a simple test to detect glucose in food products.

Journal of Agricultural and Food Chemistry, 2012
This paper reports a simple, rapid, and sugar-selective method to induce gelation from glucose-containing samples. This method employs glucose oxidase (GOx) to selectively "recognize" and oxidize glucose to generate gluconic acid, which acts to ...

Contilisant, a Tetratarget Small Molecule for Alzheimer's Disease Therapy Combining Cholinesterase, Monoamine Oxidase Inhibition, and H3R Antagonism with S1R Agonism Profile.

Journal of Medicinal Chemistry, 2018
Contilisant, a permeable, antioxidant, and neuroprotectant agent, showing high nM affinity at H3R and excellent inhibition of the monoamine oxidases and cholinesterases, is an affine and selective S1R agonist in the nanomolar range, based on the binding ...

THE EFFECT OF MONOAMINE OXIDASE INHIBITORS ON GROWTH AND THE RAT TIBIA TEST

Journal of Endocrinology, 1965
SUMMARY A large number of monoamine oxidase (MAO) inhibitors: pivhydrazine (Tersavide), nialamide (Niamide), isocarboxazid (Marplan), mebanazine (Actomol), phenelzine (Nardil), pheniprazine (Catron) and tranylcypromine (Parnate), decrease cartilage growth in normal rats. This inhibition is not directly due to their properties as MAO inhibitors.

Inhibition of monoamine oxidase-B by 5H-indeno[1,2-c]pyridazines: biological activities, quantitative structure-activity relationships (QSARs) and 3D-QSARs.

Journal of Medicinal Chemistry, 1995
A large series (66 compounds) of indeno[1,2-c]pyridazin-5-ones (IPs) were synthesized and tested on their monoamine oxidase-A (MAO-A) and MAO-B inhibitory activity.

Serum Xanthine Oxidase: A Sensitive Test of Acute Liver Injury

Gastroenterology, 1965
Summary A sensitive assay for xanthine oxidase developed in our laboratory was used for the determination of the serum level of this enzyme (SeXO) in healthy subjects as well as in patients with various clinical disorders. In patients with viral hepatitis there was a marked elevation of SeXO (300 to 2800 times the upper limit of normal) during the ...
