Accurate prediction of Drug-Target Interactions (DTIs) is crucial for drug discovery and development. While current research focuses predominantly on modern medicine, we propose DTI-BGCGCN, a novel predictive model that integrates a bipartite drug-target attribute graph with a Cluster Graph Con- volutional Network (ClusterGCN) for both modern and traditional Chinese medicine. Our approach employs a bipartite attribute graph to efficiently en- capsulate drug-target relationships and common features, while ClusterGCN classifies different graph topological structures and expedites the training process.

Artificial intelligence techniques play a pivotal role in the accurate identification of drug-drug interaction (DDI) events, thereby informing clinical decisions and treatment regimens. While existing DDI prediction models have made significant progress by leveraging sequence features such as chemical substructures, targets, and enzymes, they often face limitations in integrating and effectively utilizing multi-modal drug representations. To address these limitations, this study proposes a novel multi-modal feature fusion model for DDI event prediction: MMDDI-SSE.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has caused significant public health and socioeconomic crises across Africa; however, the prevalent patterns of COVID-19 and the circulating characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants in the continent remain insufficiently documented.

Methods: In this study, national data on case numbers, infection incidences, mortality rates, the circulation of SARS-CoV-2 variants, and key health indexes were collected from various official and professional sources between January 2020 and December 2023 were analyzed with SaTScan and geographically weighted regression (GWR).

Results: The prevalent profiles and circulating features of SARS-CoV-2 across the African continent, including its five regions and all African countries, were analyzed.

Background: Dual-energy CT (DECT) provides several novel methods to assess thrombus perviousness. We aimed to evaluate whether the novel thrombus perviousness measured with DECT is associated with improved recanalisation and better functional outcomes in acute ischaemic stroke (AIS) patients with endovascular thrombectomy (EVT).

Methods: 108 AIS patients with middle cerebral artery occlusion who underwent DECT angiography on admission and received EVT treatment between April 2020 and September 2023 were retrospectively analysed.

Neuroinflammation plays a dual role in prion diseases, contributing both to the clearance of misfolded scrapie-like prion protein and to neuropathology through chronic activation of inflammatory pathways. Key mechanisms, including M-CSF/CSF1R signaling, NLRP3 inflammasome activation, and the Galectin-3/TREM2 axis, etc., highlight the complexity of targeting neuroinflammation for therapeutic intervention.

Predicting drug-target binding affinity (DTA) is a crucial task in drug discovery research. Recent studies have demonstrated that pocket features and interactions between targets and drugs significantly improve the understanding of DTA. However, challenges remain, particularly in the detailed consideration of both global and local information and the further modeling of pocket features.

Amino acids and dipicolinic acid (DPA) are important biomarkers for identifying human health. Establishing rapid, accurate, sensitive, and simple assays is essential for disease prevention and early diagnosis. In this work, a novel Zn(II) metal-organic framework (MOF) with the formula {[Zn(μ-OH)(BTDI)(dpp)]·dpp·4HO·2DMF} (, where denotes Jiangxi University of Science and Technology, HBTDI = 5,5'-(benzo[][1,2,5]thiadiazole-4,7-diyl)diisophthalic acid; dpp = 1,3-di(4-pyridyl)propane) was successfully synthesized via a mixed-ligands strategy.

As a promising anti-tumor modality, photodynamic immunotherapy (PDIT) has been applied for the treatment of many solid tumors. However, tumor hypoxic condition and immunosuppressive microenvironment severely limit the treatment outcome of PDIT. Here, we have designed a hairpin tetrahedral DNA nanostructure (H-TDN)-modified bifunctional cascaded Pt single-atom nanozyme (PCFP@H-TDN) with encapsulation of the photosensitizer.

A new aggregation-induced emission (AIE) luminogen is obtained by dimerizing acridin-9(10H)-one (Ac), an aggregation-caused quenching (ACQ) effect monomer via an N─N bond and forming 9H,9'H-[10,10'-biacridine]-9,9'-dione (DiAc) with D symmetry. The quenching of DiAc in solution is ascribed to the enhanced basicity promoting hydrogen bonding and then a hydrogen abstraction (HA) reaction and/or an unallowed transition in frontier orbitals with the same symmetry facilitating intersystem crossing. It is found that emissive Ac is one product of the non-emissive DiAc solution in the HA reaction activated by UV irradiation.

Transcriptome-wide association study (TWAS) has successfully identified numerous complex disease susceptibility genes in the post-genome-wide association study (GWAS) era. Over the past 3 years, the focus of TWAS algorithms has shifted from merely identifying associations to understanding how single nucleotide polymorphisms (SNPs) regulate gene expression, with a growing emphasis on incorporating fine-mapping techniques. Additionally, the rapid increase in GWAS summary statistics, driven largely by the UK Biobank and other consortia, has made it essential to update our webTWAS resource.
