Role of Simulated Digests in Shaping Gut Microbiota and Short-Chain Fatty Acid Levels.

The connection between gut microbiota and factors like diet is crucial for maintaining intestinal balance, which in turn impacts the host's overall health. microalgae is a sustainable source of bioactive compounds, mainly known for its used in aquaculture and extraction of bioactive lipids, with potential health benefits whose effects on human gut microbiota are still unknown. Therefore, the goal of this work was to assess the impact of on human gut microbiota composition and derived metabolites by combining the INFOGEST protocol and in vitro colonic fermentation process to evaluate potential effects on human gut microbiota conformation through 16S rRNA gene sequencing and its metabolic functionality.

A simulated 'can't intubate, can't oxygenate' manikin crossover study investigating a modified front-of-neck access airway device.

A 'can't intubate, can't oxygenate' (CICO) situation is an uncommon and time-critical emergency. Many institutions have adopted a 'scalpel-bougie-endotracheal tube (ETT)' technique based on evidence produced by the 4th National Audit Project of the Royal College of Anaesthetists and 2015 Difficult Airway Society guidelines. We made a modification to the traditional 'scalpel-bougie-ETT' technique, using a shortened bougie and replacing the ETT with a cuffed Melker airway in a preassembled device (called 'Secure Airway for Front-of-neck Emergencies' (SAFE airway device)), which we felt might reduce cognitive load on a single operator in an emergency CICO situation.

A chromosomal mutation is superior to a plasmid-encoded mutation for plasmid fitness cost compensation.

Plasmids are important vectors of horizontal gene transfer in microbial communities but can impose a burden on the bacteria that carry them. Such plasmid fitness costs are thought to arise principally from conflicts between chromosomal- and plasmid-encoded molecular machineries, and thus can be ameliorated by compensatory mutations (CMs) that reduce or resolve the underlying causes. CMs can arise on plasmids (i.

Global genomic diversity of Pseudomonas aeruginosa in bronchiectasis.

Objectives: Pseudomonas aeruginosa is the most common pathogen in the bronchiectasis lung, associated with worsened outcomes. P. aeruginosa genomic studies in this context have been limited to single-country, European studies.
