Composites of YF: Yb, Er, Tm@CN-Au with near-infrared light-driven ability for photocatalytic wastewater purification.

Photocatalytic technology for removing organic dye pollutants has gained considerable attention because of its ability to harness abundant solar energy without requiring additional chemical reagents. In this context, YF spheres doped with Yb, Er, Tm (YF) are synthesized using a hydrothermal method and are subsequently coated with a layer of graphitic carbon nitride (g-CN) with Au nanoparticles (NPs) adsorbed onto the surface to create a core-shell structure, designated as YF: Yb, Er, Tm@CN-Au (abbreviated as YF@CN-Au). The core-shell composites demonstrate remarkable stability, broadband absorption, and exceptional photocatalytic activity across the ultraviolet (UV) to near-infrared (NIR) spectral range.

RBBP6 anchors pre-mRNA 3' end processing to nuclear speckles for efficient gene expression.

Here, a multiscale simulation strategy, enhanced by machine learning potentials are proposed, to investigate this mesoscale behavior.

Privacy protection of sexually transmitted infections information from Chinese electronic medical records.

The comprehensive adoption of Electronic Medical Records (EMRs) offers numerous benefits but also introduces risks of privacy leakage, particularly for patients with Sexually Transmitted Infections (STI) who need protection from social secondary harm.

The objective is to develop effective information extraction and privacy protection strategies to safeguard STI patients in the Chinese healthcare environment and prevent unnecessary privacy leakage during the data-sharing process of EMRs.

Computational exploration of the self-aggregation mechanisms of phenol-soluble modulins β1 and β2 in Staphylococcus aureus biofilms.

The formation of functional bacterial amyloids by phenol-soluble modulins (PSMs) in Staphylococcus aureus is a critical component of biofilm-associated infections, providing robust protective barriers against antimicrobial agents and immune defenses. Clarifying the molecular mechanisms of PSM self-assembly within the biofilm matrix is essential for developing strategies to disrupt biofilm integrity and combat biofilm-related infections. In this study, we analyzed the self-assembly dynamics of PSM-β1 and PSM-β2 by examining their folding and dimerization through long-timescale atomistic discrete molecular dynamics simulations.

Impact of Frequent ARID1A Mutations on Protein Stability: Insights into Cancer Pathogenesis.

The ARID1A gene, frequently mutated in cancer, encodes the AT-rich interactive domain-containing protein 1A, a key component of the chromatin remodeling SWI/SNF complex. The ARID1A protein features a conserved DNA-binding domain (ARID domain) of approximately 100 residues crucial for its function. Despite the frequency of mutations, the impact on ARID1A's stability and contribution to cancer progression remains unclear.

Computational insights into the aggregation mechanism of human calcitonin.

Human calcitonin (hCT) is a peptide hormone that regulates calcium homeostasis, but its abnormal aggregation can disrupt physiological functions and increase the risk of medullary thyroid carcinoma. To elucidate the mechanisms underlying hCT aggregation, we investigated the self-assembly dynamics of hCT segments (hCT, hCT, and hCT) and the folding and dimerization of full-length hCT through microsecond atomistic discrete molecular dynamics (DMD) simulations. Our results revealed that hCT and hCT predominantly existed as isolated monomers with transient small-sized oligomers, indicating weak aggregation tendencies.
