Combined effect of Tetracycline compounds and essential oils on antimicrobial resistant isolated from the swine food chain.

Antimicrobial resistance (AMR) poses risks for food stakeholders because of the spread of resistant microbes and potential foodborne diseases. In example, pigs may carry strains, which can infect humans through contaminated food preparations. Due to their antibacterial properties and capacity to modulate bacterial drug resistance, essential oils (EOs) are attracting interest as prospective substitutes for synthetic antimicrobials which can help to reverse microbial resistance.

Exploring the Metabolome and Antimicrobial Properties of L. (Baklouti and Paprika) Dried Powders from Tunisia.

In this study, for the first time, the volatile fraction from two domesticated accessions ("Paprika" and "Baklouti") collected in Tunisia was investigated by two complementary analytical techniques, such as Solid-Phase Microextraction-Gas Chromatography/Mass Spectrometry (SPME-GC/MS) and Proton Transfer Reaction-Time-of-Flight-Mass Spectrometry (PTR-ToF-MS). The obtained results highlighted the presence of a high number of Volatile Organic Compounds (VOCs), including monoterpene and sesquiterpene compounds with -curcumene, I-zingiberene, -bisabolene and -sesquiphellandrene as the major components. In addition, GC/MS was used to investigate the non-volatile chemical composition of the dried powders and their extracts, which were found to be rich in sulfur compounds, fatty acids and sugars.

The new 2023 ESC guidelines for the management of cardiomyopathies: a guiding path for cardiologist decisions.

In the ESC 2023 guidelines, cardiomyopathies are conservatively defined as 'myocardial disorders in which the heart muscle is structurally and functionally abnormal, in the absence of coronary artery disease, hypertension, valvular disease, and congenital heart disease sufficient to cause the observed myocardial abnormality'. They are morpho-functionally classified as hypertrophic, dilated, restrictive, and arrhythmogenic right ventricular cardiomyopathy with the addition of the left ventricular non-dilated cardiomyopathy that describes intermediate phenotypes not fulfilling standard disease definitions despite the presence of myocardial disease on cardiac imaging or tissue analysis. The new ESC guidelines provide 'a guide to the diagnostic approach to cardiomyopathies, highlight general evaluation and management issues, and signpost the reader to the relevant evidence base for the recommendations'.

Laser-induced 2D/0D graphene-nanoceria freestanding paper-based films for on-site hydrogen peroxide monitoring in no-touch disinfection treatments.

A one-shot CO laser-based strategy to generate conductive reduced graphene oxide (rGO) decorated with nanoceria (nCe) is proposed. The 2D/0D rGO-nCe films, integrated as catalytic sensing layers in paper-based sensors, were employed for on-site monitoring of indoor fogging treatments against Listeria monocytogenes (Lm), a ubiquitous pathogenic bacterium. The rGO-nCe laser-assisted synthesis was optimized to preserve the rGO film morphological and electron-transfer features and simultaneously integrate catalytic nCe.
