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.

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 ...

Colorimetric Biosensor Based on Magnetic Enzyme and Gold Nanorods for Visual Detection of Fish Freshness

Biosensors, 2022
Histamine, an important safety index for aquatic products, can also be used as a freshness indicator for red-fleshed fish. In this work, magnetic graphene oxide (Fe3O4@GO, MGO) was applied to immobilize diamine oxidase (DAO) through a method of ...

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.

Postheparin Plasma Diamine Oxidase In Subjects With Small-bowel Mucosal Atrophy

, 1987
Diamine oxidase (DAO) is an enzyme whose low plasma values are enhanced by an intravenous injection of heparin, which releases the enzyme from the enterocytes of the villous tips.

Optimization of agro-technological processing parameters to enhance diamine oxidase activity in edible legume sprouts

Journal of Agriculture and Food Research
Histamine intolerance is associated with impaired histamine metabolism caused by a deficiency of the enzyme diamine oxidase (DAO). A recommended strategy to alleviate symptoms is a low-histamine diet supplemented with exogenous DAO.

Nutritional Intervention With Perennial Ryegrass Modulates UA Metabolism in Goslings via Gut Microbiota–Antioxidant Pathway Modulation

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Perennial ryegrass supplementation modulates UA‐metabolism in goslings by reducing serum uric acid and creatinine through inhibition of hepatic xanthine oxidase and upregulation of urate transporters (ABCG2, OAT1, OAT3). It enhances antioxidant capacity via Nrf2 activation, improves intestinal barrier integrity, and enriches beneficial gut microbiota ...
