The management of chronic infected wounds remains a significant clinical challenge, largely due to the deficiency of optimal wound dressings with adequate mechanical strength, appropriate adhesiveness, and efficient sustainable antibacterial, reactive oxygen species (ROS) scavenging, pro-angiogenesis, and immunomodulation properties. To address such a dilemma, we employed a simple and facile strategy to utilize resveratrol (RSV) as a functional component to mediate hydrogel gelation in this study. The structure of this obtained hydrogel was supported by a multibond network, which not only endowed the resultant product with superior mechanical strength and moderate adhesiveness but also effectively prolonged the bioavailability of RSV.

State Key Lab of Geohazard prevention & Geoenvironment protection, College of Materials and Chemistry & Chemical Engineering, Chengdu University of Technology, Chengdu 610059, China. Electronic address:

Sulfur nanoparticles (SNPs) and their composites are promising for heavy metal adsorption, yet current SNPs often lack surface S, leading to low affinity toward heavy metal and ease of aggregation. Here, we report a simple light-driven method for facile prepare SNPs with surfaces enriched with S and in-situ load them onto graphene oxide (GO) to fabricate GO-S composites. Under illumination, the O generated by photosensitizer phloxine B was able to oxidize S into elemental SNPs.

The ultraviolet-activated peroxymosnofulate (UV/PMS) system, an effective advanced oxidation process for removing dissolved organic matter (DOM) from wastewater, is limited by high chloride ion (Cl) concentrations in landfill leachate. This study used Fourier transform ion cyclotron resonance mass spectrometry to explore the transformation of DOM in the UV/PMS system with a high Cl concentration. The results revealed that elevated Cl levels generate reactive chlorine species, including chlorine radicals, dichlorine radicals, and hypochlorous acid/hypochlorite, reducing the total organic carbon (TOC) removal efficiency of Suwannee River natural organic matter (SRNOM) from 78.

The Human Pangenome Reference Consortium, the Chinese Pangenome Consortium, and other plant and animal pangenome projects have announced the completion of pilot work aimed at constructing high-quality, haplotype-resolved reference graph genomes representative of global ethno-linguistically different populations or different plant and animal species. These graph-based, gapless pangenome references, which are enriched in terms of genomic diversity, completeness, and contiguity, have the potential for enhancing long-read sequencing (LRS)-based genomic research, as well as improving mappability and variant genotyping on traditional short-read sequencing platforms. We comprehensively discuss the advancements in pangenome-based genomic integrative genomic discoveries across forensic-related species (humans, animals, and plants) and summarize their applications in variant identification and forensic genomics, epigenetics, transcriptomics, and microbiome research.

Electronic address:

In order to enhance the anti-HIV-1 potency and selectivity of the previously reported compound 3 (EC = 27 nM, SI = 1361), a series of novel biphenyl-diarylpyrimidine derivatives were developed by employing structure-based drug design strategy. Among these derivatives, compound M44 demonstrated the most potent inhibitory activity against wild-type (WT) HIV-1 as well as five drug-resistant mutants (EC = 5-148 nM), which were 5-173 times more potent than that of 3 (EC = 27-9810 nM). Furthermore, this analogue exhibited approximately 11-fold lower cytotoxicity (CC = 54 μM) than that of etravirine and rilpivirine.

Accurate segmentation of brain tumors from MRI scans is a critical task in medical image analysis, yet it remains challenging due to the complex and variable nature of tumor shapes and sizes. Traditional convolutional neural networks (CNNs), while effective for local feature extraction, struggle to capture long-range dependencies crucial for 3D medical image analysis. To address these limitations, this paper presents VcaNet, a novel architecture that integrates a Vision Transformer (ViT) with a fusion channel and spatial attention module (CBAM), aimed at enhancing 3D brain tumor segmentation.
