Diet–Microbiome–Immune Interactions at the Gut Mucosa in Food Allergy: Mechanisms, Gaps, and Therapeutic Implications

open access: yesAllergy, Volume 81, Issue 10, Page 3439-3452, October 2026.
ABSTRACT Mucosal surfaces are sites of highly dynamic interactions among epithelial and immune cells, environmental exposures, particularly dietary inputs, and the diverse microbial communities and their metabolites. These elements continually influence each other to maintain homeostasis and ensure appropriate immune discrimination between pathogens ...

PEPC of sugarcane regulated glutathione S-transferase and altered carbon–nitrogen metabolism under different N source concentrations in Oryza sativa

open access: yesBMC Plant Biology, 2021
Background Phosphoenolpyruvate carboxylase (PEPC) plays an important role in the primary metabolism of higher plants. Several studies have revealed the critical importance of PEPC in the interaction of carbon and nitrogen metabolism.

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

open access: yesFEBS Open Bio, Volume 16, Issue 9, Page 1645-1656, September 2026.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

KINETICS OF THE ENZYMICALLY-CATALYZED OXIDATION OF INDOLEACETIC ACID

open access: yes, 1956
A study of the kinetics of the enzymically-catalyzed decarboxylation and oxidation of indoleacetic acid has provided evidence that it is a chain autoxidation initiated and propagated by two enzyme-controlled peroxidations.

Response of Substituted Indoleacetic Acids in the Indolo-alpha-pyrone Fluorescence Determination

open access: yes, 1978
The method of indolo-.alpha.-pyrone fluorescence-determination of IAA was investigated to study possible interference from 4-chloro-indoleacetic acid and 5-hydroxyindoleacetic acid, which occur naturally. Both compounds show about 40% of the fluorescence

Studies on the inactivation of indoleacetic acid by roots [PDF]

open access: yes, 1962
The enzymatic breakdown of indoleacetic acid in the presence of aqueous pea root extracts containing an "indoleacetic acid-oxidase" system was studied. A method based on the "Salkowski" colour reaction was used for the estimation of residual indoleacetic
