Flexible Chemiresistive Chitosan‐Glycerol Sensors on Laser‐Induced Graphene Electrodes for Room‐Temperature Ammonia Detection

Advanced Materials Technologies, EarlyView.
Flexible Chitosan‐glycerol sensor integrated with porous laser‐induced graphene (LIG) electrodes enable room‐temperature chemiresistive detection of ammonia (NH3) and proof‐of‐concept detection of fish spoilage. ABSTRACT We report a metal‐free sensor platform combining laser induced graphene (LIG) electrodes with drop‐deposited, glycerol‐plasticized ...

Reduction of trimethylamine N-oxide to trimethylamine by the human gut microbiota: supporting evidence for ‘metabolic retroversion’ [PDF]

, 2015
Dietary sources of methylamines such as choline, trimethylamine (TMA), trimethylamine N-oxide (TMAO), phosphatidylcholine (PC) and carnitine are present in a number of foodstuffs, including meat, fish, nuts and eggs.

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.

The Role of the Gut Microbiota in Allogeneic Hematopoietic Cell Transplantation

American Journal of Hematology, EarlyView.
ABSTRACT Allogeneic hematopoietic cell transplantation (allo‐HCT) is an effective treatment for patients with high‐risk hematologic malignancies. Over the last decade, gut microbiota composition during allo‐HCT has been associated with patients' outcomes.

Gut microbiota in atherosclerosis: focus on trimethylamine N‐oxide [PDF]

APMIS, 2020
The increasing prevalence of cardiovascular diseases cannot adequately be explained by traditional risk factors. Recently, accumulating evidence has suggested that gut microbiota‐derived numerous metabolites are contributors to atherosclerotic events.

Trimethylamine N-oxide—a marker for atherosclerotic vascular disease

Reviews in Cardiovascular Medicine, 2021
As a potential causative factor in various cardiovascular diseases, the gut microbe-generated metabolite trimethylamine N-oxide (TMAO) has courted considerable research interest as a potential biomarker. TMAO is a small molecule considered to be beneficial for the health of deep-water animals due to its ability to protect proteins against hydrostatic ...

Nuclear magnetic resonance studies of blood plasma and urine from subjects with chronic renal failure: identification of trimethylamine-N-oxide

, 1991
We have used 1H-, 13C- and 14N-NMR spectroscopy to investigate the constituents of plasma and urine in 16 patients with chromic renal failure (CRF). Resonances not previously observed in spectra of plasma from healthy volunteers were seen in CRF plasma ...

Evaluation of a pantoprazole and 4‐desmethylpantoprazole‐sulfate metabolic ratio as a novel CYP2C19 phenotyping method

British Journal of Clinical Pharmacology, EarlyView.
Aims CYP2C19 is one of the most important pharmacogenes, and its activity is highly variable due to factors such as genetics or drug–drug interactions. Due to the lack of an appropriate endogenous CYP2C19 biomarker, surrogate methods to assess its activity are warranted.

Trimethylamine N-Oxide as a Potential Biomarker for Cardiovascular Disease: Its Association with Dietary Sources of Trimethylamine N-Oxide and Microbiota

The Eurasian Journal of Medicine, 2023
Trimethylamine N-oxide (TMAO), the oxidized form of trimethylamine (TMA), was previously thought to be a waste product but is now considered an important risk factor for cardiovascular disease (CVD) and its comorbidities. Foods or supplements containing choline and carnitine are major precursors of TMA in the diet and are metabolized by gut microbiota.
