Standardization of a colorimetric technique for determination of enzymatic activity of diamine oxidase (DAO) and its application in patients with clinical diagnosis of histamine intolerance

World Allergy Organization Journal, 2020
Background: Diamine Oxidase (DAO) has an essential role for degradation of exogenous histamine in the intestine; thus, histamine intolerance (HI) mainly has been correlated to a low concentration and/or activity of this enzyme. The objective of the study

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...

Mechanistic Studies on Diamine Oxidase [PDF]

, 1995
To investigate the enzyme pea seedling diamine oxidase our studies concentrated on three main areas: 1. mechanistic studies of the oxidative deamination of primary diamines catalysed by diamine oxidase; 2.

Copper reduction by substrate in diamine oxidase [PDF]

FEBS Letters, 1969
Pig kidney diamine oxidase (diamine: oxygen oxidoreductase, EC 1.4.3.6) similarly to other amine oxidases [ 1,2] , contains cupric copper and pyridoxal phosphate [3-61. The copper content of pig kidney diamine oxidase.is 1 g atom of metal per 90,000 g of protein.

Bile acid metabolism and signaling in human and animal health: A One Health perspective

iMetaOmics, EarlyView.
Bile acids maintain host homeostasis through enterohepatic circulation, microbial transformation, and bile acid receptor signaling, thereby regulating glucose and lipid metabolism, intestinal barrier integrity, and immunity. These effects support human disease intervention and health‐oriented animal production, reducing drug dependence and residue ...

Substrates and Inhibitors of Diamine Oxidase [PDF]

, 1993
This thesis describes a study of the enzyme pea seedling diamine oxidase (ps DAO) and concentrates on four main areas: (1) enzyme-catalysed oxidation of primary diamines by pea seedling diamine oxidase (2) oxidation of pyridine-amines by pea seedling ...

Modified high-performance liquid chromatographic determination of diamine oxidase activity in plasma [PDF]

, 1990
A previous high-performance liquid chromatographic determination of diamine oxidase activity suitable for tissue homogenates was modified in order to adapt it to plasma samples. Simple additional steps were introduced after the enzyme reaction and before

Inhibiting Copper Amine Oxidase Using L-Aminoguanidine Induces Cultivar and Age-Dependent Alterations of Polyamine Catabolism in Tomato Seedlings

Agriculture, 2022
Many effects of polyamines (PAs) are well known in plant developmental processes; however, the significance of their catabolism is not well understood. Copper amine oxidase (CuAO) is involved in the degradation of diamine putrescine (Put).

Colonic Barrier Dysfunction and Inflammation Induced by Nano‐/Micro‐Plastics Fibers in Mice via the FAK/NF‐κB/iNOS and TLR4/NF‐κB/iNOS Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT As emerging environmental contaminants, nano‐ and micro‐plastics (NMPs) have drawn increasing research attention due to potential hazards to organisms. Particle shape is a key factor influencing the toxic effects of NMPs, and NMPs of different shapes cause varying degrees of tissue damage. We investigated the specific mechanisms of polystyrene
