Biodiversity and antibiotic resistance profile provide new evidence for a different origin of enterococci in bovine raw milk and feces
Food Microbiol. 2024 Jun;120:104492. doi: 10.1016/j.fm.2024.104492. Epub 2024 Feb 18.ABSTRACTEnterococci are widely distributed in dairy sector. They are commensals of the gastrointestinal tract of animals, thus, via fecal contamination, could reach raw milk and dairy products. The aims of this study were: 1) to investigate the enterococcal diversity in cow feces and milk samples and 2) to evaluate the antibiotic resistance (AR) of dairy-related enterococci and their ability to transfer resistance genes. E. faecalis (59.9%), E. faecium (18.6%) and E. lactis (12.4%) were prevalent in milk, while E. faecium (84.2%) and E. hi...

The effects of drug-drug interaction on linezolid pharmacokinetics: A systematic review
ConclusionsThis systematic review found that numerous drugs have an impact on the pharmacokinetics of linezolid, and the purported main mechanism may be that linezolid is the substrate of P-glycoprotein. In clinical practice, it is prudent to pay attention to the changes in linezolid pharmacokinetics caused by interactions. Conducting therapeutic drug monitoring (TDM) is beneficial to improve efficacy and reduce adverse reactions of linezolid. (Source: European Journal of Clinical Pharmacology)

Unlocking Amides: A General Method for the Self-Immolative Release of Amide-Containing Molecules
Angew Chem Int Ed Engl. 2024 Feb 27:e202402267. doi: 10.1002/anie.202402267. Online ahead of print.ABSTRACTThe controlled liberation of molecules from a constructed framework is a subject of profound interest across various chemical fields. It allows for the masking of a molecule's properties and precise deployment upon a single controllable release event. While numerous methodologies have been developed for amines, alcohols, and thiols, approaches for utilising amides as payload-release handles are still in their early stages of development, despite the prevalence of amides in therapeutic compounds and materials. Herein, ...

A systematic efficacy analysis of tuberculosis treatment with BPaL ‐containing regimens using a multiscale modeling approach
In this study, we present a unique framework that uses a primate granuloma modeling approach to screen many combination regimens that are currently under clinical and experimental exploration and assesses their efficacies to inform future studies. We tested well-studied regimens such as HRZE and BPaL to evaluate the validity and accuracy of our framework. We also simulated additional promising combination regimens that have not been sufficiently studied clinically or experimentally, and we provide a pipeline for regimen ranking based on their efficacies in granulomas. Furthermore, we showed a correlation between simulation...
