Engineered Bacillus subtilis regulates intestinal barrier in ETEC K88‐infected piglets and modulates miR‐1250‐5p/NFκB pathway in IPEC‐J2

iMetaOmics, Volume 3, Issue 2, June 2026.
Upon enterotoxigenic Escherichia coli (ETEC) K88 infection, intestinal barrier function is disrupted with compromised tight junctions, accompanied by an exacerbated inflammatory response, proliferation of pathogenic Escherichia, and depletion of beneficial Lactobacillus paralimentarius.

Modifications In Ornithine Decarboxylase and Diamine Oxidase In Small Bowel Mucosa of Starved and Refed Rats

, 1987
Starvation followed by refeeding, which provides a model of intestinal adaptation characterised by proliferative and biochemical changes, was used to clarify the biological roles of ornithine decarboxylase (ODC) and diamine oxidase (DAO)--enzymes ...

Dao (diaminoxidase) purification from natural sources and enzyme-enriched food production

Applied Food Research
Histamine intolerance, affecting approximately 1–3 % of the population, is linked to elevated histamine levels that can mimic allergic reactions. Diamine oxidase (DAO) plays a key role in histamine degradation.

Magnolol Improves Intestinal Antioxidant Capacity and Barrier Function by Activating the Nrf2 Signaling Pathway in a Piglet Model

Food Frontiers, Volume 7, Issue 3, May 2026.
ABSTRACT Magnolol is a natural bioactive phenolic compound with potent antioxidant properties and plays an important role in modulating intestinal healthy. However, the underlying mechanisms of magnolol in alleviating intestinal oxidative stress damage and improving the intestinal barrier integrity remain unknown. Thus, this study aimed to evaluate the

Monitoring Biogenic Amines: Comparative Assessment of Detection Methods for Key Market Marine and Freshwater Species

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Biogenic amines, primarily histamine, cadaverine, and putrescine, are important indicators of microbial spoilage and potential health risks. This review summarizes established and novel analytical methods for quantitatively determining biogenic amines in fish and fish products, along with their limits of detection in these complex matrices ...

H2‐Driven Whole‐Cell Conversion of Diamines to N‐Heterocycles by Recombinant Cupriavidus necator

ChemCatChem, Volume 18, Issue 7, 14 April 2026.
A Cupriavidus necator chassis couples a diamine oxidase–imine reductase cascade with an H2‐driven soluble hydrogenase cofactor module to convert linear diamines into saturated N‐heterocycles in vivo, using H2 as the sole source of reducing power.
