Electron flow to dimethylsulphoxide or trimethylamine-N-oxide generates a membrane potential in Rhodopseudomonas capsulata

, 1983
Under dark and essentially anaerobic conditions electron flow to either dimethylsulphoxide or trimethylamine-N-oxide in cells of Rhodopseudomonas capsulata has been shown to generate a membrane potential.

Direct Growth of BODIPY‐Based Conjugated Porous Polymer Shell on Upconversion Nanoparticles for NIR‐Driven Photocatalysis

Small, EarlyView.
Monomer prefunctionalization of upconversion nanoparticles directs uniform growth of BODIPY‐based conjugated porous polymers shells, affording precise control over polymer loading and optimized NIR‐triggered photocatalytic activity. ABSTRACT The great applications of upconversion nanoparticles (UCNPs) can be further extended by their encapsulation ...

Gut microbiota dysbiosis in the inflammatory pathogenesis of diabetic retinopathy

VIEW, EarlyView.
This graphical abstract illustrates how gut dysbiosis drives diabetic retinopathy through the gut‐retina axis, a process unfolding in three interconnected stages. First, in the gut, a decrease in beneficial bacteria and an increase in pro‐inflammatory taxa compromise the intestinal barrier, causing a “leaky gut” that allows LPS to translocate into the ...

Hydration of trimethylamine-N-oxide and of dimethyldodecylamine-N-oxide: An ab initio study

, 2007
Density functional theory (B3LYP) calculations of the hydration of trimethylamine-N-oxide (TMAO) and a surfactant dimethyldodecylamine-N-oxide (DDAO) are reported.

The effect of the osmolyte trimethylamine N-oxide on the stability of the prion protein at low pH [PDF]

, 2006
A study of the effect of trimethylamine N-oxide on the stability of two recombinant forms of the prion protein PrP, an ovine full-length and a human truncated form, is here reported.

Association Characteristics and Potential Mechanisms of Aging, Gut Microbiota, and Hearing Loss

Integrative Zoology, EarlyView.
The study found that aging leads to unchanged gut microbiota alpha diversity but an increase in Bacteroidetes and a decrease in Firmicutes at the phylum level, with specific genera, species, and functional pathways co‐associated with aging and hearing loss. Through constructing a microbe‐metabolite network, it revealed the mechanism by which protective

Gut Microbe-Generated Metabolite Trimethylamine-N-Oxide and Ischemic Stroke

Biomolecules
Trimethylamine-N-oxide (TMAO) is a gut microbiota-derived metabolite, the production of which in vivo is mainly regulated by dietary choices, gut microbiota, and the hepatic enzyme flavin monooxygenase (FMO), while its elimination occurs via the kidneys.

Role of urea and methylamines in buoyancy of elasmobranchs [PDF]

, 1994
The possible role of urea and trimethylamine oxide (TMAO) in providing positive buoyancy has been examined for elasmobranch fishes. TMAO has a considerably lower density than an equimolar solution of urea, and solutions of both TMAO and urea are ...

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 ...

Alamandine/MrgD pathway modulates gut–bone marrow axis in ageing

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ageing is associated with colon epithelial barrier disruption and up‐regulation of myelopoiesis in the bone marrow (BM). Alamandine (Ala) and MrgD are novel members of the renin angiotensin system (RAS). This study tested the hypothesis that Ala restores the colon epithelial barrier integrity in ageing via modulating gut–
