Crystalline silica on the lung-environment interface: Impact on immunity, epithelial cells, and therapeutic perspectives for autoimmunity.

Crystalline silica (the most abundant form of silicon dioxide) is a natural element that is ubiquitous in the Earth's crust. Chronic personal or professional exposure has been implicated in various pathologies, including silicosis and autoimmune diseases since the early 20th century. More recently, a specific pathogenic role for crystalline silica has been identified through its impact on lung epithelial cells as well as immune cells present at this organism barrier.

Craving changes in first 14 days of addiction treatment: an outcome predictor of 5 years substance use status?

Addiction is considered a chronic disorder that requires long-term treatment. Early identification of predictors of outcome may enable better and early adjustment of treatment. Daily fluctuations of craving have been shown to predict substance use within hours, making it a major target for treatment.

Deciphering circulating tumor cells binding in a microfluidic system thanks to a parameterized mathematical model.

The spread of metastases is a crucial process in which some questions remain unanswered. In this work, we focus on tumor cells circulating in the bloodstream, the so-called Circulating Tumor Cells (CTCs). Our aim is to characterize their trajectories under the influence of hemodynamic and adhesion forces.

Mobilization of DNAPL lenses in heterogeneous aquifers using shear-thinning PEO polymers: Experimental and numerical study.

Polymer solution injection has emerged as a promising method for the remediation of NAPL (non-aqueous phase liquids)-contaminated aquifers. This technique enhances recovery efficiency by modifying viscous forces, stabilizing the displacement front, and minimizing channeling effects. However, there remains a significant gap in understanding the behavior of polymer solutions, particularly those with different molecular weights (MW), for mobilizing DNAPL (dense non-aqueous phase liquids) trapped in heterogeneous aquifers, especially within low-permeability layers.

Self-diffusion in isotropic and liquid crystalline phases of fd virus colloidal rods: a combined single particle tracking and differential dynamic microscopy study.

In this article, we investigate the dynamics of self-organised suspensions formed by rod-like fd virus colloids. Two methods have been employed for analysing fluorescence microscopy movies: single particle tracking (SPT) in direct space and differential dynamic microscopy (DDM) in reciprocal space. We perform a quantitative analysis on this anisotropic system with complex diffusion across different self-assembled states, ranging from dilute and semi-dilute liquids to nematic and smectic organisations.

Morphological . molecular identification of trematode species infecting the edible cockle across Europe.

Identifying marine trematode parasites in host tissue can be complicated when there is limited morphological differentiation between species infecting the same host species. This poses a challenge for regular surveys of the parasite communities in species of socio-economic and ecological importance. Our study focused on identifying digenean trematode species infecting the marine bivalve across Europe by comparing morphological and molecular species identification methods.

An efficient joint model for high dimensional longitudinal and survival data via generic association features.

This paper introduces a prognostic method called FLASH that addresses the problem of joint modeling of longitudinal data and censored durations when a large number of both longitudinal and time-independent features are available. In the literature, standard joint models are either of the shared random effect or joint latent class type. Combining ideas from both worlds and using appropriate regularization techniques, we define a new model with the ability to automatically identify significant prognostic longitudinal features in a high-dimensional context, which is of increasing importance in many areas such as personalized medicine or churn prediction.

Dealing With the Complexity of Effective Population Size in Conservation Practice.

Effective population size () is one of the most important parameters in evolutionary biology, as it is linked to the long-term survival capability of species. Therefore, greatly interests conservation geneticists, but it is also very relevant to policymakers, managers, and conservation practitioners. Molecular methods to estimate rely on various assumptions, including no immigration, panmixia, random sampling, absence of spatial genetic structure, and/or mutation-drift equilibrium.

Assessment of a next generation sequencing gene panel strategy in 133 patients with negative thrombophilia screening.

Background: Although heritability of venous thromboembolism (VTE) is high, the thrombophilia screening appears to be positive only in a minority of VTE patients. Adding rare variants screening to identify VTE missing heritability still requires further assessment.

Objective: We report the results of a panel strategy after 3 years of application.

Prevalence and correlates of alexithymia in drug-resistant epilepsies.

Introduction: Alexithymia, characterized by difficulty identifying and expressing emotions, is commonly observed in individuals with psychiatric and neurological disorders. However, its prevalence in patients with epilepsy (PWE), particularly in those with drug-resistant epilepsy (DRE), remains under-researched. This study investigates the prevalence of alexithymia in patients with DRE and explores its associated factors.

3D real-time single particle tracking using two-photon fluorescence from bright dye-based organic nanoparticles.

This paper addresses the use of ultrabright dye-based fluorescent organic nanoparticles in a 3D single-particle tracking two-photon microscopy setup. The nanoparticles consist of an assembly of quadrupolar dyes, presenting a large two-photon absorption cross-section. They exhibit low photobleaching, crucial for long-term tracking, and their high brightness allows nanometer localization precision.

Energy metabolism rewiring following acute UVB irradiation is largely dependent on nuclear DNA damage.

Solar ultraviolet B (UVB) radiation-induced DNA damage is a well-known initiator of skin carcinomas. The UVB-induced DNA damage response (DDR) involves series of signaling cascades that are activated to maintain cell integrity. Among the different biological processes, little is known about the role of energy metabolism in the DDR.

Evaluation of clonal hematopoiesis and mosaic loss of Y chromosome in cardiovascular risk: An analysis in prospective studies.

Background: Clonal hematopoiesis of indeterminate potential (CHIP) was initially linked to a twofold increase in atherothrombotic events. However, recent investigations have revealed a more nuanced picture, suggesting that CHIP may confer only a modest rise in myocardial infarction (MI) risk. This observed lower risk might be influenced by yet unidentified factors that modulate the pathological effects of CHIP.

Solvent effects on the second harmonic responses of donor-acceptor Stenhouse adducts: from implicit to hybrid solvation models.

The effect of conformational dynamics and solvent interactions on the second-order nonlinear optical (NLO) responses of the open and closed forms of a donor-acceptor Stenhouse adduct (DASA) are investigated by a mixed quantum/classical computational approach, which couples molecular dynamics (MD) simulations and time-dependent density functional theory (TD-DFT) calculations. The latter are further combined with various solvation schemes, including polarizable continuum models, hybrid QM/MM approaches using either non polarizable or polarizable electrostatic embedding, and QM/QM' schemes with explicit treatment of a few molecules of the first solvation shell. The performances of the different solvation models are discussed in the context of comparisons with experimental data obtained from hyper-Rayleigh scattering measurements.

Remission from addiction: erasing the wrong circuits or making new ones?

Chronic relapse is a hallmark of substance-use disorders (SUDs), but many people with SUDs do recover and eventually enter remission. Many preclinical studies in this field aim to identify interventions that can precipitate recovery by reversing or erasing the neuronal circuit changes caused by chronic drug use. A better understanding of remission from SUDs can also come from preclinical studies that model factors known to influence recovery in humans, such as the negative consequences of drug use and positive environmental influences.

Near-Infrared Light-Induced Spin-State Switching Based on Fe(II)-Hg(II) Spin-Crossover Network.

The development of molecular switches with tunable properties has garnered considerable interest over several decades. A novel spin-crossover (SCO) material based on iron(II) complexes incorporating 4-acetylpyridine (4-acpy) and [Hg(SCN)] anions was synthesized and formulated as [Fe(4-acpy)][Hg(μ-SCN)] (1). Compound 1 is crystallized in a three-dimensional network in the non-centrosymmetric orthorhombic space group Pna2 with two octahedral [Fe(4-acpy)(NCS)] entities featuring two distinct Fe centers (Fe1 and Fe2).

Predicting high variability in imageability ratings across age groups and its influence on visual word recognition.

Imageability, an important word characteristic in the psycholinguistic literature, is typically assessed by asking participants to estimate the ease with which a word can evoke a mental image. Our aim was to explore inter-rater disagreement in normative imageability ratings. We examined the predictors of variability around average imageability ratings for young, middle-aged and older adults (Study 1) and assessed its impact on visual word recognition performance in young adults (Study 2).

Medications for Opioid Use Disorder in People Who Inject Substances: Reflection on the Potential Place of Morphine Sulfate as Substitution Treatment? Results of COSINUS Cohort Study.
