Dual functionalization of carboxymethyl cellulose and alginate via Passerini three-component reaction to graft two hydrophobic moieties: Toward modular thin films.

Carbohydr Polym

March 2025

Université Claude Bernard Lyon 1, INSA Lyon, Université Jean Monnet, CNRS UMR 5223, Ingénierie des Matériaux Polymères, F-69621 Cédex, France. Electronic address:

Passerini reaction was advantageously exploited to hydrophobize carboxymethyl cellulose (CMC) and alginates (ALG) by employing various hydrophobic aldehydes and isocyanides. The Passerini reaction, carried out in ecofriendly conditions, allowed to design never described twofold hydrophobized polysaccharide derivatives via the covalent grafting of two hydrophobic moieties. The modified CMC and ALG products were in-depth characterized to guaranty the success of the modification and to calculate the degrees of substitution (DS).

Transcranial Direct Current Stimulation (tDCS) has shown potential in modulating cortical activity and treating depression. Despite its promise, variability in electrode montage configurations and electric field strength across studies has resulted in inconsistent outcomes. Traditional meta-analytic methods assessing the effect of tDCS in depression typically do not compare tDCS montage and the anatomical distribution of electric field, which is a major source of inter-experimental variability.

Leishmaniasis is a neglected tropical disease caused by protozoans of the Leishmania genus, against which no effective treatment or control is available. Like other eukaryotes, parasite telomeres are maintained by telomerase, a ribonucleoprotein complex vital for genome stability. Its protein component, TERT (telomerase reverse transcriptase), presents four structural and functional domains, with the TEN (Telomerase N-terminal) and TRBD (Telomerase RNA-binding) located at its N-terminal.

Water scarcity in the Mediterranean area has increased the number of intermittent rivers. Recently, hyporheic zones (HZ) of intermittent rivers have gained attention since a substantial part of the stream's natural purification capacity is located within these zones. Thus, understanding the flow dynamics in HZs is crucial for gaining insights into the degradation of organic micropollutants.

The aim of the study was to identify distinct trajectories of perceived stress and control in athletes across a season of sports competitions and whether these trajectory memberships could be predicted by subdimensions of the emotional intelligence (EI). Latent class growth analyses were performed on a five-stage longitudinal measurement plan (to cover the entire sporting season). Four hundred fifteen athletes answered to the Brief Emotional Intelligence Scale, the Mastery Scale, the Perceived Stress Scale, and the Attainment of Sport Achievement Goal Scale.

The mRNA splicing machinery has been estimated to generate 100,000 known protein-coding transcripts for 20,000 human genes (Ensembl, Sept. 2024). However, this set is expanding with the massive and rapidly growing data coming from high-throughput technologies, particularly single-cell and long-read sequencing.

Perfluorooctanesulfonic acid (PFOS) is one of the most investigated Per- and polyfluoroalkyl substances (PFAS) for being the strongest compound to eliminate and having adverse health concerns. In this work, we have conducted the sonochemical treatment of PFOS simulated water under high (500 kHz) and low (22 kHz) frequencies while monitoring the operational parameters via an integrated sonochemical system. The integrated advanced sonochemical system includes software to monitor treatment power, solution temperature and frequency while allowing distinctive control of the reaction conditions.

Plastic products contain complex mixtures of chemical compounds that are incorporated into polymers to improve material properties. Besides the intentional chemical additives, other compounds including residual monomers and non-intentionnaly added substances (NIAS) as well as sorbed pollutants are usually also present in aged plastic. Since most of these substances are only loosely bound to the polymer via non-covalently interactions, i.

Model of drop infiltration into a thin amphiphilic porous medium.

J Colloid Interface Sci

January 2025

UMR1114 EMMAH INRAE-AU, 228, Route de L'Aérodrome, Avignon, F84000, France. Electronic address:

Hypothesis: Water drop infiltration into a thin amphiphilic porous medium is influenced by wettability. Due to the reorganization of amphiphilic matter in contact with water, polar interaction changes the wettability in the bulk porous medium and at the liquid/porous substrate interface. To model out of equilibrium water transfer, we propose a thermodynamics approach derived from Onsager's principle.

In this study, a novel imidazolium-based ionic liquid (IL) coating was developed for stir bar sorptive extraction (SBSE) using a sol-gel method. The effects of different counterions, conditioning temperatures and polymer compositions were investigated. The stir bar with bis((trifluoromethyl)sulfonyl) amide 1-butyl-3-(3-(triethoxysilyl)propyl)-1H-imidazol-3-ium showed good mechanical and thermal stability with high resistance to water solubilization.

Introduction: Lyme borreliosis (LB), an infection caused by Borrelia burgdorferi sensu lato (Bbsl), is the most common tick-borne disease in Europe. To further characterize the LB burden in the Czech Republic, we conducted a seroprevalence study and estimated the incidence of symptomatic Bbsl infections.

Methods: Anti-Bbsl IgM and IgG antibodies were detected in sera collected from the adult population in 2011 -2012 by enzyme-linked immunosorbent assay and immunoblot tests at the National Reference Laboratory.

Synthetic Aspects and Characterization Needs in MOF Chemistry - from Discovery to Applications.

Adv Mater

January 2025

Institut des Matériaux Poreux de Paris, Ecole Normale Supérieure, ESPCI Paris, CNRS, PSL University, Paris, 75005, France.

Even if MOFs are recently developed for large-scale applications, the road to applications of MOFs is long and rocky. This requires to overcome challenges associated with phase discovery, synthesis optimization, basic and advanced characterization, and computational studies. Lab-scale results need to be transferred to large-scale processes, which is often not trivial, and life-cycle analyses and techno-economic analyses need to be performed to realistically assess their potential for industrial relevance.

Aims: Secondary mitral regurgitation (SMR) and tricuspid regurgitation (TR) are the most common valvular heart diseases in patients with heart failure (HF). Transcatheter edge-to-edge repair (TEER) devices designed for treating MR and TR have been successfully tested in randomized controlled trials, but methodological issues have often challenged their interpretation. This manuscript aimed to provide an overview of TEER registries on SMR and TR in HF, highlighting their key features, describing clinical characteristics and outcomes of patients receiving these devices, and exploring the available data limitations.

It is striking that visual attention, the process by which attentional resources are allocated in the visual field so as to locally enhance visual perception, is a pervasive component of models of eye movements in reading, but is seldom considered in models of isolated word recognition. We describe BRAID, a new Bayesian word-Recognition model with Attention, Interference and Dynamics. As most of its predecessors, BRAID incorporates three sensory, perceptual, and orthographic knowledge layers together with a lexical membership submodel.

Hepato-Pancreato-Biliary Surgery and Liver Transplantation, Pôle des Pathologies Digestives et Hépatiques, Hôpital de Hautepierre-Hôpitaux Universitaires de Strasbourg, Université de Strasbourg, Strasbourg, France.

Background: The use of multiagent FOLFIRINOX chemotherapy for pancreatic adenocarcinoma in a neoadjuvant setting has been associated with an increased rate of complete pathological response (CPR) after surgery. This study investigated the long-term outcomes of patients with CPR in a multicenter setting to identify prognostic factors for overall survival (OS) and recurrence-free survival (RFS).

Methods: This retrospective cohort study examined biopsy-proven pancreatic adenocarcinomas with CPR after neoadjuvant chemotherapy or chemoradiotherapy and surgery, between January 2006 and December 2023 across 22 French and  2 Belgian centers.
