Development of a Voltammetric Amine Oxidase-Modified Biosensor for the Determination of Biogenic Amines in Food

International Journal of Electrochemical Science, 2012
A novel, stable biosensor for the detection of biogenic amines (BAs) was designed by immobilizing pea seedling amine oxidase (PSAO) on MnO2 modified carbon paste electrodes (CPEs).

Coordination‐Tuned Iridium Single‐Atom Nanozymes Boost Multienzyme Activity for Colorimetric Sensing

Advanced Science, Volume 13, Issue 55, 5 October 2026.
Breaking the coordination symmetry of Ir single‐atom sites through asymmetric Ir–N3S1 engineering tailors interfacial electron transfer, oxygen activation, and multienzyme‐like catalytic pathways. Operando spectroscopy and theoretical modeling uncover the atomic‐level origin of activity enhancement, providing a strategy for designing multifunctional ...

β-N-Methylamino-L-Alanine (BMAA) Modulates the Sympathetic Regulation and Homeostasis of Polyamines

Toxins, 2023
The neurotoxin β-N-methylamino-L-alanine (BMAA) is a non-proteinogenic amino acid produced by cyanobacteria. Non-neuronal toxicity of BMAA is poorly studied with a reported increase in reactive oxygen species and a decrease in the antioxidant capacity of

Imine Reductase‐Mediated Regio‐ and Stereoselective Reductive Amination of Diamines

ChemCatChem, Volume 18, Issue 19, 14 October 2026.
Imine reductases (IREDs) have been employed as biocatalysts for the regioselective modification of diamines via reductive amination. The use of racemic diamines resulted in both regio‐ and enantio‐selective reductive amination via kinetic resolution. The application of this methodology has been demonstrated on a preparative scale by the synthesis of a ...

Some properties of diamine oxidase from Pisum sativum [PDF]

Partial purification of diamine oxidase from pea seedlings, Pisum sativum, was accomplished by homogenization of 8-10 day etiolated epicotyl tissue, followed by ammonium sulfate fractionation and DEAE Sephadex column chromatography.

Catechols, Catecholamines, and Hydroxylated Naphthalene Derivatives as Building Blocks for the Electrochemical Deposition of Thin Films: Mechanisms and Properties

ChemElectroChem, Volume 13, Issue 19, 1 October 2026.
This review describes cyclic voltammetry or chronamperometry of phenol derivatives, catecholamines, and hydroxylated naphthalenes on electrodes. Under strong oxidative conditions the solutes are mineralized, but in the electrochemical stability window of the solvent, the electrode undergoes passivation or deposition of porous (eventually conductive ...

Electroacupuncture Ameliorates Alcohol‐Related Cognitive Impairment by Modulating the Gut‐Brain Axis to Alleviate LPS Driven Neuroinflammation

CNS Neuroscience &Therapeutics, Volume 32, Issue 10, October 2026.
Electroacupuncture at ST36 can ameliorate alcohol‐related cognitive impairment by modulating the gut‐brain axis to alleviate LPS driven neuroinflammation. It is a potential strategy for preventing and treating ARCI. ABSTRACT Objective To investigate whether electroacupuncture (EA) at Zusanli (ST36) ameliorates alcohol‐related cognitive impairment (ARCI)

The diamine oxidase gene is associated with hypersensitivity response to non-steroidal anti-inflammatory drugs. [PDF]

PLoS ONE, 2012
UnlabelledNon-steroidal anti-inflammatory drugs (NSAIDs) are the drugs most frequently involved in hypersensitivity drug reactions. Histamine is released in the allergic response to NSAIDs and is responsible for some of the clinical symptoms.

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

Food Safety and Health, Volume 4, Issue 4, Page 824-859, October 2026.
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 ...

Dissimilar Pain of Primary Epiploic Appendagitis and Malabsorption [PDF]

Journal of Clinical and Diagnostic Research, 2017
Primary Epiploic Appendagitis (PEA) is a rare cause of acute or subacute abdominal complaints and non-migratory pain. Usually the diagnosis of PEA is made when Computed Tomography (CT) reveals characteristic figures.
