Exploring Surface State and Exciplex Dominated Aggregation Induced Electrochemiluminescence of Graphene Quantum Dots Prepared Via Electrochemical Exfoliation.

Graphene quantum dots (GQDs) have emerged as promising materials for electrochemiluminescence (ECL) applications due to their unique optical and electronic properties. In this study, GQDs were synthesized via electrochemical exfoliation of graphite in a constant current density mode, enabling scalable production with controlled size and surface functionalization. GQDs-4 and GQDs-20, synthesized at applied current densities of 4 mA/cm2 and 20 mA/cm2 to the graphite electrode, respectively, were investigated on roles of surface states and exciplex dominated aggregation-induced emission (AIE) in their ECL performance.

The Effects of Exergaming on the Depressive Symptoms of People With Dementia: A Systematic Review and Meta-Analysis.

Background: Depressive symptoms are common among people with dementia (PWD). Exergaming consisting of combined cognitive and physical training in gaming is increasingly used to alleviate their depressive symptoms in research. With its potential synergistic neurobiological and psychosocial effects on reducing depressive symptoms among PWD, this review aimed to understand its effectiveness and contents.

An animal model of severe acute respiratory distress syndrome for translational research.

Background: Despite the fact that an increasing number of studies have focused on developing therapies for acute lung injury, managing acute respiratory distress syndrome (ARDS) remains a challenge in intensive care medicine. Whether the pathology of animal models with acute lung injury in prior studies differed from clinical symptoms of ARDS, resulting in questionable management for human ARDS. To evaluate precisely the therapeutic effect of transplanted stem cells or medications on acute lung injury, we developed an animal model of severe ARDS with lower lung function, capable of keeping the experimental animals survive with consistent reproducibility.

Functional analysis and modification of anti-lipopolysaccharide factor (ALF) from the freshwater crab Sinopotamon henanense and preparation of a novel ShALF6-2 K-AgNPs complex.

Overuse of antibiotics has led to the emergence of drug-resistant bacteria and environmental problems. Antimicrobial peptides (AMPs) and silver nanoparticles (AgNPs) can potentially replace antibiotics. Therefore, it is possible to create composite nanostructures with synergistic bactericidal properties by combining AgNPs and AMPs.

Cripto-1 acts as a molecular bridge linking nodal to ALK4 via distinct structural domains.

The TGF-β family ligand Nodal is an essential regulator of embryonic development, orchestrating key processes such as germ layer specification and body axis formation through activation of SMAD2/3-mediated signaling. Significantly, this activation requires the co-receptor Cripto-1. However, despite their essential roles in embryogenesis, the molecular mechanism through which Cripto-1 enables Nodal to activate the SMAD2/3 pathway has remained elusive.
