Objectives: Epidemiological treatment for suspected Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections is recommended for exposed partners before laboratory confirmation, within 14 days of exposure to reduce symptoms, break transmission chains, and prevent loss of follow-up. This approach may lead to potential antibiotic overuse by uninfected individuals, thereby enhancing antimicrobial resistance. This study investigated the accuracy of epidemiological treatment for CT and NG.

Introducing a Depressurization Step in Online LCxSFC Modulation.

Anal Chem

February 2025

Universite Claude Bernard Lyon 1, ISA UMR 5280, CNRS, 5 rue de la Doua, 69100 Villeurbanne, France.

New online LCxSFC valve technologies have recently been developed, based on the transfer of the first-dimension eluent either in the CO stream or in the cosolvent stream of the SFC dimension. While using the appropriate valve configuration greatly improved peak shapes, the reduction of the analysis time remained a challenge. A compromise between high first-dimension flow rate, to reduce gradient time, and low second-dimension injected volume, to limit injection effects, is to implement a flow split upstream of the valve.

More than 50 ​% of patients undergoing mechanical thrombectomy (MT) for ischemic stroke have a poor functional outcome despite timely and successful angiographic reperfusion, highlighting the need for adjunctive treatments to reperfusion therapy. Mitochondria are key regulators of cell fate, by controlling cell bioenergetics via oxidative phosphorylation (OXPHOS) and cell death through the mitochondrial permeability transition pore (mPTP). Whether these two main mitochondrial functions are altered by reperfusion and could represent a new cytoprotective approach remains to be elucidated in mice.

Service de Neurologie, Centre Hospitalier Universitaire (CHU) Nantes, Institut National de la Santé et de la Recherche Médicale (INSERM), Centre d'Investigation Clinique (CIC), Center for Research in Transplantation, Nantes Université.

Background And Objectives: Older studies reported an increased risk of relapse after in vitro fertilization (IVF) in women with multiple sclerosis (MS), which has not been confirmed by more recent works. All these studies had several limitations, such as small sample sizes, absence of a control population, or lack of neurologic validation of the relapses. The aim of this study was to determine the risk of relapse after IVF in women with MS.

Variation in the fitness impact of translationally optimal codons among animals.

Genome Res

March 2025

Laboratoire de Biométrie et Biologie Évolutive, Université Lyon 1, UMR CNRS 5558, Villeurbanne, France;

Early studies in invertebrate model organisms (fruit flies, nematodes) showed that their synonymous codon usage is under selective pressure to optimize translation efficiency in highly expressed genes (a process called translational selection). In contrast, mammals show little evidence of selection for translationally optimal codons. To understand this difference, we examined the use of synonymous codons in 223 metazoan species, covering a wide range of animal clades.

Experiments have shown that surfactant introduced to a liquid-filled maze can find the solution path. We reveal how the maze-solving dynamics arise from interactions between the added surfactant and endogenous surfactant present at the liquid surface. We simulate the dynamics using a nonlinear model solved with a discrete mimetic scheme on a graph.

Benchtop NMR is becoming an increasingly important tool, sometimes providing a simple and low-cost alternative to high-field NMR. The Achilles heel of NMR and even more critically of benchtop NMR is its limited sensitivity. However, when combined with hyperpolarization techniques, the sensitivity boost can provide excellent sensitivity that can even make benchtop NMR compatible with affinity studies for drug discovery.

The random motion of molecules in living cells has consistently been reported to deviate from standard Brownian motion, a behavior coined as "anomalous diffusion." To study this phenomenon in living cells, fluorescence correlation spectroscopy (FCS) and single-particle tracking (SPT) are the two main methods of reference. In opposition to SPT, FCS, with its classical analysis methodology, cannot consider models of motion for which no analytical expression of the auto-correlation function is known.

Electronic address:

Phenylketonuria (PKU) treatment requires a low-phenylalanine (Phe) diet limiting natural protein intake, using medical low-protein foods and Phe-free amino acids (AA) supplements along with micronutriments' supplies. Current recommendations suggest maintaining this diet for life to prevent neuro-psychological effects of high Phe concentrations. The long-term consequences of such a diet are poorly understood, particularly on bone health.

Although both motor imagery (MI) and low-frequency sound listening have independently been shown to modulate brain activity, the potential synergistic effects that may arise from their combined application remains unexplored. Any further modulation derived from this combination may be relevant for motor learning and rehabilitation. We probed neurophysiological activity during these two processes, measuring alpha and beta band power amplitude by means of EEG recordings.
