Structural Transformation and Degradation of Cu Oxide Nanocatalysts during Electrochemical CO Reduction.

The electrochemical CO reduction reaction (CORR) holds enormous potential as a carbon-neutral route to the sustainable production of fuels and platform chemicals. The durability for long-term operation is currently inadequate for commercialization, however, and the underlying deactivation process remains elusive. A fundamental understanding of the degradation mechanism of electrocatalysts, which can dictate the overall device performance, is needed.

Novel Antibacterial 4-Piperazinylquinoline Hybrid Derivatives Against : Design, Synthesis, and In Vitro and In Silico Insights.

Molecular hybridization, which consists of the combination of two or more pharmacophores into a single molecule, is an innovative approach in drug design to afford new chemical entities with enhanced biological activity. In the present study, this strategy was pursued to develop a new series of 6,7-dimethoxy-4-piperazinylquinoline-3-carbonitrile derivatives (-) with potential antibiotic activity by combining the quinoline, the piperazinyl, and the benzoylamino moieties, three recurrent frameworks in antimicrobial research. Initial in silico evaluations were conducted on the designed compounds, highlighting favorable ADMET and drug-likeness properties, which were synthesized through a multistep strategy, isolated, and fully characterized.

More Than the Sum of Its Parts: Disrupted Core Periphery of Multiplex Brain Networks in Multiple Sclerosis.

Disruptions to brain networks, measured using structural (sMRI), diffusion (dMRI), or functional (fMRI) MRI, have been shown in people with multiple sclerosis (PwMS), highlighting the relevance of regions in the core of the connectome but yielding mixed results depending on the studied connectivity domain. Using a multilayer network approach, we integrated these three modalities to portray an enriched representation of the brain's core-periphery organization and explore its alterations in PwMS. In this retrospective cross-sectional study, we selected PwMS and healthy controls with complete multimodal brain MRI acquisitions from 13 European centers within the MAGNIMS network.

Cognitive reserve predicts long-term cognitive trajectories in relapsing-remitting multiple sclerosis.

Background: The effect of cognitive reserve (CR) on cognition in people with relapsing-remitting multiple sclerosis (pwRRMS) has been partially investigated.

Objectives: We aimed to explore the long-term cognitive trajectories of pwRRMS based on their CR, measured using the Vocabulary Knowledge Test (VOC).

Methods: 78 pwRRMS underwent a neuropsychological evaluation at baseline and after a mean follow-up of 6.

Effect of autoimmune comorbidities on multiple sclerosis course: An observational multicenter study.

Background: The study aims to examine the age and disability levels at diagnosis in people with multiple sclerosis (PwMS), with and without autoimmune comorbidities (AC), and the effect of AC on NEDA-3 status and to characterize AC associated with MS, comparing also therapeutic approaches between MS patients with and without other AC.

Methods: This population-based, multicentric study enrolled patients with relapsing-remitting MS (RRMS) with AC (AC group) or without AC (reference group) from 14 MS centers. Demographical, clinical features, treatment information, MRI activity, EDSS, and no evidence of disease activity (NEDA-3) status were assessed at T36 (enrollment time) and T0 (36 months prior).
