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.

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 ...

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the risk of food poisoning due to the presence of biogenic amines in meals made from chicken meat consumed by children under 3 years of age

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Biogenic amines are low molecular weight organic bases that come from the enzymatic decarboxylation of amino acids. They are present in many types of food, with the highest concentrations usually found in fish and their derived products, as well as in beverages and fermented foods of plant, meat and dairy origin.

Carboxymethyl starch: Chitosan monolithic matrices containing diamine oxidase and catalase for intestinal delivery [PDF]

, 2012
The capacity of carboxymethyl starch (CMS):Chitosan monolithic tablets to protect diamine oxidase and/or catalase therapeutic enzymes against simulated gastric fluid (SGF) and to control their delivery in simulated intestinal fluid (SIF) was investigated.

Aging Triggers an Intestinal Energy Crisis and HDL3 Deficiency Disrupting Gut–Liver Axis Homeostasis

Aging Cell, Volume 25, Issue 3, March 2026.
The age‐related mitochondrial energy crisis and the consequent disruption of intestinal HDL3 biosynthesis converge to disrupt the gut–liver HDL3‐LPS/TLR4 axis, compromising hepatic anti‐inflammatory function and driving liver injury, an effect reversible upon NMN administration.

Circadian profiling reveals higher histamine plasma levels and lower diamine oxidase serum activities in 24% of patients with suspected histamine intolerance compared to food allergy and controls [PDF]

, 2017
Histamine intolerance is thought to trigger manifold clinical symptoms after ingesting histamine-rich food due to reduced activity of diamine oxidase (DAO).

Microbial‐Immune Interplay in CNS Autoimmune Diseases: Lessons from Animal Models and Clinical Studies

European Journal of Immunology, Volume 56, Issue 2, February 2026.
Mechanism of action of the intestinal microbiota on CNS autoimmune diseases. Environmental factors shape gut microbiota composition; dysbiosis alters microbial metabolites and antigenic signals. These modulate innate and adaptive immunity, affect barrier integrity, and influence CNS‐resident cells such as microglia and astrocytes, contributing to ...

Nitrate Enhances Gastric Mucosa Defense and Repair Process in Ethanol‐Induced Gastric Ulcer Rats via the Notch–Tff2 Pathway

MedComm, Volume 7, Issue 2, February 2026.
Nitrate protects the three major barriers of the gastric mucosa, alleviating bleeding and inflammation of ethanol‐induced gastric ulcer in rats, and promotes migration of gastric epithelial cells, accelerating the restoration of the ulcerated epithelium, which is strongly related to TFF2, a gastric mucosal protective factor negatively regulated by the ...
