Nanocurvature‐Activated Dipolar Polarization in M–N4 Single‐Atom Sites for High‐Performance Electromagnetic Wave Absorption

Advanced Science, EarlyView.
Increasing nanocurvature effectively enriches the local electron density of the M–N4 motif, which facilitates electron transfer from the metal center to nitrogen atoms. This electronic behavior intensifies the localization and asymmetric distribution of charge, thereby significantly amplifying the dipole moment and polarizability.

Metabolic retroconversion of trimethylamine N-oxide and the gut microbiota

Microbiome, 2018
Background The dietary methylamines choline, carnitine, and phosphatidylcholine are used by the gut microbiota to produce a range of metabolites, including trimethylamine (TMA).

Relationship between red meat metabolite trimethylamine N-oxide and cardiovascular disease

Heart and Mind, 2022
Many cardiovascular diseases (CVD) are caused by the interplay of lifestyle and genetic factors. Studies have suggested an association between red meat consumption and increased CVD risk. There is evidence indicating that trimethylamine N-oxide (TMAO), a

O2-independent demethylation of trimethylamine N-oxide by Tdm of Methylocella silvestris [PDF]

, 2016
Bacterial trimethylamine N-oxide (TMAO) demethylase, Tdm, carries out an unusual oxygen-independent demethylation reaction, resulting in the formation of dimethylamine and formaldehyde.

Gut microbiota metabolite trimethylamine N-oxide promoted NAFLD progression by exacerbating intestinal barrier disruption and intrahepatic cellular imbalance.

International Immunopharmacology
Non-alcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease worldwide, with the gut microbiota and its metabolites are important regulators of its progression.

Contribution of Trimethylamine N-Oxide (TMAO) to Chronic Inflammatory and Degenerative Diseases

Biomedicines, 2023
Trimethylamine N-oxide (TMAO) is a metabolite produced by the gut microbiota and has been mainly associated with an increased incidence of cardiovascular diseases (CVDs) in humans. There are factors that affect one’s TMAO level, such as diet, drugs, age,
