Co-option of neck muscles supported the vertebrate water-to-land transition.

A major event in vertebrate evolution was the separation of the skull from the pectoral girdle and the acquisition of a functional neck, transitions that required profound developmental rearrangements of the musculoskeletal system. The neck is a hallmark of the tetrapod body plan and allows for complex head movements on land. While head and trunk muscles arise from distinct embryonic mesoderm populations, the origins of neck muscles remain elusive.

MRI management of NMOSD and MOGAD: Proposals from the French Expert Group NOMADMUS.

Background: Currently, there are no available recommendations or guidelines on how to perform MRI monitoring in the management of neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). The issue is to determine a valuable MRI monitoring protocol to be applied in the management of NMOSD and MOGAD, as previously proposed for the monitoring of multiple sclerosis.

Objectives: The objectives of this work are to establish proposals for a standardized and feasible MRI acquisition protocol, and to propose control time points for systematic MRI monitoring in the management of NMOSD and MOGAD.

Ocrelizumab in Early-Stage Relapsing-Remitting Multiple Sclerosis: The Phase IIIb ENSEMBLE 4-Year, Single-Arm, Open-Label Trial.

Background And Objectives: Early treatment of multiple sclerosis (MS) reduces disease activity and the risk of long-term disease progression. Effectiveness of ocrelizumab is established in relapsing MS (RMS); however, data in early RMS are lacking. We evaluated the 4-year effectiveness and safety of ocrelizumab as a first-line therapy in treatment-naive patients with recently diagnosed relapsing-remitting MS (RRMS).

[Effects of air pollution on eye health].

EFFECTS OF AIR POLLUTION ON EYE HEALTH. In addition to its well-known effects on cardio-respiratory health, air pollution could also have an impact on eye health. Indeed, certain air pollutants, especially fine particles and nitrogen dioxide, can enter the bloodstream, triggering oxidative and inflammatory mechanisms involved in the development of the major eye diseases (glaucoma, age-related macular degeneration [AMD], cataracts).

Reconciling Pollen Limitation Theories: Insights From Temperate Oak Masting.

Pollen limitation has a considerable influence on forest masting, the highly variable and synchronised seed production, on which forest regeneration and ecosystem dynamics largely rely. Depending on the various mechanisms possibly involved in pollen limitation, the consequences of climate change on masting could be very different. These mechanisms were investigated in 10 oak populations along a climatic gradient using surveys of airborne pollen and fruiting rate as a proxy of pollen limitation.

Membrane mechanics dictate axonal pearls-on-a-string morphology and function.

Axons are ultrathin membrane cables that are specialized for the conduction of action potentials. Although their diameter is variable along their length, how their morphology is determined is unclear. Here, we demonstrate that unmyelinated axons of the mouse central nervous system have nonsynaptic, nanoscopic varicosities ~200 nm in diameter repeatedly along their length interspersed with a thin cable ~60 nm in diameter like pearls-on-a-string.

Molecular interactions driving the complexation of rose bengal by triazine-carbosilane dendrons.

Amphiphilic dendrons or Janus dendrimers self-assembling into nanoscale vesicles offer promising avenues for drug delivery. Triazine-carbosilane dendrons have shown great potential for the intracellular delivery of rose bengal, additionally enhancing its phototoxic activity through non-covalent interactions. Thus, understanding the complexation dynamics between dendrons and photosensitizers is crucial for the development of efficient drug carriers.

Modified neuroimmune processes and emotional behaviour in weaned and late adolescent male and female mice born via caesarean section.

Elective and emergency Caesarean section (C-section) procedures are on the rise, exceeding the recommended guidelines by the World Health Organization. Higher morbidities and long-term health conditions are correlated to C-section deliveries, including neurodevelopmental disorders. During C-section delivery, newborns are not exposed to the vaginal commensal flora, which impedes the early establishment of the gut microbiota.

NSAID exposure delays time-to-pregnancy in patients with spondyloarthritis: an analysis of the GR2 prospective cohort.

Background: The impact of disease activity and treatment on fertility outcomes in patients with spondyloarthritis (SpA) has been little explored. This study aimed to describe median time to pregnancy (TTP) in women with SpA and the factors influencing TTP in this population.

Methods: This prospective observational multicentre (63 centres) French cohort (GR2 study-NCT02450396) included consecutive women with a diagnosis of SpA (according to their rheumatologist) who wanted to become pregnant between 2015 and 2021.

[Use of HemoCue® or portable hemoglobinometer: results of the national surveys carried out by the SFBC POCT working group].

Hemoglobin (Hb) measurement is a fundamental biological test, especially in emergency situations where rapid medical decisions are required. Portable hemoglobinometers, such as HemoCue®, provide a delocalized solution for capillary whole blood. The SFBC's POCT News and Issues working group designed and conducted two national surveys to assess the use and management of these devices, both on the clinical and biological side, with 306 and 160 responses respectively.

Blood metabolomic profiling reveals new targets in the management of psychological symptoms associated with severe alcohol use disorder.

Background: Alcohol use disorder (AUD) is a global health problem with limited therapeutic options. The biochemical mechanisms that lead to this disorder are not yet fully understood, and in this respect, metabolomics represents a promising approach to decipher metabolic events related to AUD. The plasma metabolome contains a plethora of bioactive molecules that reflects the functional changes in host metabolism but also the impact of the gut microbiome and nutritional habits.

[Screening for sleep disorders in internal medicine as potential comorbidities of systemic autoimmune diseases and improving patients' quality of life].

Sleep medicine and internal medicine share a global and transdisciplinary vision of human physiology and illnesses, with an approach guided by the complaint and semiology. In France, approximately 13 to 18 million individuals suffer from a sleep disorder: these disorders therefore represent a public health problem. Their comorbidities with systemic autoimmune diseases are frequent.

Transcatheter Edge-to-Edge Repair for Severe Isolated Tricuspid Regurgitation: The Tri.Fr Randomized Clinical Trial.

Importance: Correction of tricuspid regurgitation using tricuspid transcatheter edge-to-edge repair (T-TEER) in addition to guideline-directed optimized medical therapy (OMT) may improve clinical outcomes.

Objective: To evaluate the efficacy of T-TEER + OMT vs OMT alone in patients with severe, symptomatic tricuspid regurgitation.

Design, Setting, And Participants: Investigator-initiated, prospective, randomized (1:1) trial evaluating T-TEER + OMT vs OMT alone in adult patients with severe, symptomatic tricuspid regurgitation.

Scattering of CO from Vacant-MoSe with O Adsorbates: Is CO Formed?

Using ab initio molecular dynamics (AIMD) simulations, based on density functional theory that also accounts for van der Waals interactions, we study the oxidation of gas-phase CO on MoSe with a Se vacancy and oxygen coverage of 0.125 ML. In the equilibrium configuration, one of the O atoms is adsorbed on the vacancy and the other one atop one Se atom.

Bessel Beam Femtosecond Laser Interaction with Fused Silica Before and After Chemical Etching: Comparison of Single Pulse, MHz-Burst, and GHz-Burst.

We investigate the elongated modifications resulting from a Bessel beam-shaped femtosecond laser in fused silica under three different operation modes, i.e., the single-pulse, MHz-burst, and GHz-burst regimes.

[Between the normal and the pathological: The concept of pre-disease applied to systemic autoimmune rheumatic diseases].

The incidence of systemic autoimmune diseases is constantly rising. They are chronic diseases requiring prolonged treatment, with considerable psychosocial impact. While attention to the promising results obtained with CAR-T cells in refractory patients is justified, it seems important not to overlook the opportunities for prevention based on the identification of a pre-disease state.

Toward understanding grapevine responses to climate change: a multistress and holistic approach.

Recent research has extensively covered the effects of climate change factors, such as elevated CO2, rising temperatures and water deficit, on grapevine (Vitis spp.) biology. However, the assessment of the impacts of multiple climate change-related stresses on this crop remains complex due to the large number of interactive effects among environmental factors and the regulatory mechanisms that underlie these effects.

Pervaporation-driven electrokinetic energy harvesting using poly(dimethylsiloxane) microfluidic chips.

Electrokinetic energy harvesting from evaporation-driven flows in porous materials has recently been the subject of numerous studies, particularly with the development of nanomaterials with high conversion efficiencies. The configuration in which the energy conversion element is located upstream of the element which passively drives the evaporative flow has rarely been studied. However, this configuration offers the possibility of increasing the harvested energy simply by increasing the evaporation surface area and/or the hydraulic resistance of the energy conversion element.

Machine learning in knee injury sequelae detection: Unravelling the role of psychological factors and preventing long-term sequelae.

Purpose: This study evaluated the performance of three machine learning (ML) algorithms-decision tree (DT), multilayer perceptron (MLP) and extreme gradient boosting (XGB)-in identifying regular athletes who suffered a knee injury several months to years prior. In addition, the contribution of psychological variables in addition to biomechanical ones in the classification performance of the ML algorithms was assessed, to better identify factors to get back to competitive sport with the lowest possible risk of new knee injury.

Methods: A cohort of 96 athletes, 36 with prior knee injuries, practicing an average of 5.

Integrating gene expression analysis and ecophysiological responses to water deficit in leaves of tomato plants.

Soil water deficit (WD) significantly impacts plant survival and crop yields. Many gaps remain in our understanding of the synergistic coordination between molecular and ecophysiological responses delaying substantial drought-induced effects on plant growth. To investigate this synergism in tomato leaves, we combined molecular, ecophysiological, and anatomical methods to examine gene expression patterns and physio-anatomical characteristics during a progressing WD experiment.
