Electronic polarization and dispersion are decisive actors in determining interaction energies between molecules. These interactions have a particularly profound effect on excitation energies of molecules in complex environments, especially when the excitation involves a significant degree of charge reorganization. The direct reaction field (DRF) approach, which has seen a recent revival of interest, provides a powerful framework for describing these interactions in quantum mechanics/molecular mechanics (QM/MM) models of systems, where a small subsystem of interest is described using quantum chemical methods and the remainder is treated with a simple MM force field.

Background: The -metric value is generally used as the importance score of a feature (or a set of features) in a classification context. This study aimed to go further by creating a new methodology for multivariate feature selection for classification, whereby the -metric is associated with a specific search direction (and therefore a specific stopping criterion). As three search directions are used, we effectively created three distinct methods.

Self-assembly is a powerful strategy for building nanosystems for biomedical applications. We have recently developed small amphiphilic dendrimers capable of self-assembling into nanomicelles for tumor imaging. In this context, we studied the impact of increased hydrophobicity of the amphiphilic dendrimer on hydrophilic/hydrophobic balance and consequently on the self-assembly and subsequent biodistribution.

Purpose: This study assessed the measurements of the medial posterior tibial slope (MPTS) using long radiographs and three-dimensional (3D) computed tomography (CT) scans and compared them to measurements taken on short lateral knee radiographs. The study aimed to identify whether the at-risk slope measurements previously defined on the short radiographs would be similar to long radiographs and 3D CT scans.
Methods: A retrospective radiological review of 52 cases, who underwent planning for a slope-changing high tibial osteotomy and had short and long lateral radiographs and 3D CT scans of the tibia.

Background: Non-invasive photobiomodulation therapy (PBMT), employing specific infrared light wavelengths to stimulate biological tissues, has recently gained attention for its application to treat neurological disorders. Here, we aimed to uncover the cellular targets of PBMT and assess its potential as a therapeutic intervention for multiple sclerosis (MS).
Methods: We applied daily dorsoventral PBMT in an experimental autoimmune encephalomyelitis (EAE) mouse model, which recapitulates key features of MS, and revealed a strong positive impact of PBMT on the sensorimotor deficits.

While waves, swells and currents are important drivers of the ocean, their specific influence on the biocolonization of marine surfaces has been little studied. The aim of this study was to determine how hydrodynamics influence the dynamics of microbial communities, metabolic production, macrofoulers and the associated vagile fauna. Using a field device simulating a shear stress gradient, a multi-scale characterization of attached communities (metabarcoding, LC-MS, biochemical tests, microscopy) was carried out for one month each season in Toulon Bay (northwestern Mediterranean).

Background: The prevalence of syphilis, Chlamydia trachomatis (CT), and Neisseria gonorrhoeae (NG) in men who have sex with men (MSM) is very high. As these bacterial sexually transmitted infections (bSTIs) are frequently asymptomatic, they are often undiagnosed and therefore untreated. We aimed to characterize the profile of MSM who reported bSTI screening and diagnosis in the previous 12 months, and to identify the factors associated with a diagnosis of a bSTI among MSM in France.

While the COVID-19 crisis is still ongoing, a new public health threat has emerged with recent outbreaks of monkeypox (mpox) infections in Africa. Mass vaccination is not currently recommended by the World Health Organization (WHO), and antiviral treatments are yet to be specifically approved for mpox, although existing FDA-approved drugs (Tecovirimat, Brincidofovir, and Cidofovir) may be used in severe cases or for immunocompromised patients. A first-line of defense is thus drug repurposing, which was heavily attempted against SARS-CoV-2 - albeit with limited success.

It is currently unclear how Pseudomonadota, a phylum that originated around the time of the Great Oxidation Event, became one of the most abundant and diverse bacterial phyla on Earth, with metabolically versatile members colonizing a wide range of environments with different O2 concentrations. Here, we address this question by studying isoprenoid quinones, which are central components of energy metabolism covering a wide range of redox potentials. We demonstrate that a dynamic repertoire of quinone biosynthetic pathways accompanied the diversification of Pseudomonadota.

Lanthanide nanoparticles (LnNPs) feature sharp emission lines together with millisecond emission lifetimes which make them promising luminescent probes for biosensing and bioimaging. Although LnNPs are attracting much interest, their photoluminescence properties at the single nanoparticle level remain largely unexplored. Here, we employ fluorescence correlation spectroscopy (FCS) and photoluminescence burst analysis to investigate the photodynamics of Sm- and Eu-based LnNPs with single nanoparticle sensitivity and microsecond resolution.

Introduction: Cannabis and cannabidiol (CBD) may potentially alleviate symptoms and improve the quality of life of people with Parkinson's disease (PD), although clinical results to date have provided conflicting evidence. In France, cannabis use is illegal outside the current restricted medical cannabis experimental framework which does not include PD as an eligible condition. In contrast, CBD products are legal and are easily available.

We report the synthesis and characterization of two chiral binuclear iridium(III) complexes ( and ) prepared from enantiopure building blocks [μ-Cl(Δ-Ir(C^N))] and [μ-Cl(Λ-Ir(C^N))]. These building blocks have been obtained by chiral preparative high-performance liquid chromatography of the neutral iridium(III) complex (piv = 2,2,6,6-tetramethylheptane-3,5-dionate) followed by selective degradation of the ancillary ligand. For comparison purposes, we also synthesized a monomer () and a dimer (, mixture).

Mosquito-borne viruses represent a large global health burden. With geographic expansion of competent vectors for chikungunya virus (CHIKV), dengue virus (DENV), and Zika virus (ZIKV) in Europe, it is anticipated that the number of autochthonous cases of these tropical viruses in Europe will increase. Therefore, regular assessment of diagnostic capabilities in Europe is important.
