Biochemical and structural elucidation of the L-carnitine degradation pathway of the human pathogen Acinetobacter baumannii

Frontiers in Microbiology
Acinetobacter baumannii is an opportunistic human pathogen which can use host-derived L-carnitine as sole carbon and energy source. Recently, an L-carnitine transporter (Aci1347) and a specific monooxygense (CntA/CntB) for the intracellular cleavage of L-

On the Determination of Trimethylamine and Trimethylamine Oxide

NIPPON SUISAN GAKKAISHI, 1957
The extraction of trimethylamine (TMA) with toluene was found to be affected by temperature, sorts of alkali and number of shaking times, as shown in Fig. 1 and Table 1, whereas the color development of TMA with picric acid was not influenced by temperature.

From Two‐Electron to Four‐Electron System: Electrolyte Regulation for Advanced Aqueous Zn–I2 Batteries

Carbon Energy, EarlyView.
This review systematically summarizes recent progress in electrolyte‐regulated aqueous Zn–I2 batteries (AZIBs). It outlines the fundamentals of AZIBs along with their main challenges, and then analyzes electrolyte‐engineering strategies that improve both two‐ and four‐electron reactions.

Microcoulometric analysis of trimethylamine dehydrogenase [PDF]

Biochemical Journal, 1988
Trimethylamine dehydrogenase, which contains one covalently bound 6-S-cysteinyl-FMN and one Fe4S4 cluster per subunit of molecular mass 83,000 Da, was purified to homogeneity from the methylotrophic bacterium W3A1. Microcoulometry at pH 7 in 50 mM-Mops buffer containing 0.1 mM-EDTA and 0.1 M-KCl revealed that the native enzyme required the addition of ...

A‐optimal model‐based design of experiments for processes with uncertain inputs

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Model‐based design of experiments (MBDoE) techniques are tools for selecting experimental conditions that enable accurate parameter estimation for mechanistic models. Most MBDoE approaches assume that the selected experimental conditions will be implemented perfectly, without uncertainties in the independent variables.

Understanding the mechanisms of efficacy of fecal microbiota transplant in treating recurrent Clostridioides difficile infection and beyond: the contribution of gut microbial-derived metabolites

Gut Microbes, 2020
Fecal microbiota transplant (FMT) is a highly-effective therapy for recurrent Clostridioides difficile infection (rCDI), and shows promise for certain non-CDI indications.

Cardiovascular‐Kidney‐Metabolic Syndrome in People With HIV: An Emerging Frontier for Clinical Pharmacology

Clinical Pharmacology &Therapeutics, EarlyView.
As antiretroviral therapy (ART) prolongs lifespans, people with HIV (PWH) face a new syndemic: Cardiovascular‐Kidney‐Metabolic (CKM) syndrome. Yet CKM in PWH is poorly characterized. Inflammation, complex pharmacokinetic (PK) alterations, ART‐associated metabolic effects, and gut dysbiosis amplify risk. Managing CKM increases medication burden, thereby
