Unveiling the hidden dance: SPP1 + macrophages identified in ulcerative colitis reveal crosstalk with CHI3L1 + fibroblasts.

Background: Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by persistent inflammation of the colon. The specific cause of UC is still not fully understood, but this condition is believed to arise from a combination of environmental, genetic, microbial, and immune factors. This study aimed to explore the specific roles of macrophages and fibroblasts in UC pathogenesis, focusing on their interactions and contributions to disease progression.

Glucosamine supplementation contributes to reducing the risk of type 2 diabetes: Evidence from Mendelian randomization combined with a meta-analysis.

ObjectiveObservational studies on glucosamine supplementation and type 2 diabetes risk have shown inconsistent results, necessitating the use of Mendelian randomization to clarify the true causal relationship.MethodsThe glucosamine supplementation-related genome-wide association study dataset was obtained from the MRC Integrative Epidemiology Unit consortium, whereas type 2 diabetes-related genome-wide association study datasets were obtained from the FinnGen consortium (discovery) and Xue et al.'s meta-analysis (validation).

Nomograms based on clinical factors to predict abnormal metabolism of psychotropic drugs.

Interindividual variability in drug metabolism serves a critical role in the occurrence of adverse drug reactions. Factors such as age, sex, body mass index (BMI) and liver and renal function can influence the metabolism of antipsychotic medications. To the best of our knowledge, however, clinical prediction models based on these factors for estimating drug-metabolizing capacity have not yet been developed.

Gastrointestinal traits, common inflammatory disorders, gallstones, and biliary tract cancer: A network Mendelian randomization study.

Introduction: Observational studies have shown that gallstone disease (GSD), cholecystitis, cholangitis, polyp of gallbladder, viral hepatitis, pancreatitis and gastrointestinal (GI) traits such as H. pylori infection, inflammatory bowel disease, and digestive ulcer are associated with the risk of biliary tract cancer (BTC). However, no study has explored their causal associations.

A conserved methyltransferase active site residue of Zika virus NS5 is required for the restriction of STING activation and interferon expression.

Zika virus (ZIKV) is a re-emerging RNA virus and causes major public health events due to its link to severe neurological complications in foetuses and neonates. The cGAS-STING signalling pathway regulates innate immunity and plays an important role in the invasion of DNA and RNA viruses. This study reveals a distinct mechanism by which ZIKV restricts the cGAS-STING signalling to repress IFN-β expression.

A transcriptome based molecular classification scheme for cholangiocarcinoma and subtype-derived prognostic biomarker.

Previous studies on the molecular classification of cholangiocarcinoma (CCA) focused on certain anatomical sites, and disregarded tissue contamination biases in transcriptomic profiles. We aim to provide universal molecular classification scheme and prognostic biomarker of CCAs across anatomical locations. Comprehensive bioinformatics analysis is performed on transcriptomic data from 438 CCA cases across various anatomical locations.

Currently, there are no approved ZIKV-specific vaccines or drugs for the clinical treatment of the infection.

Single-cell RNA sequencing highlights the role of PVR/PVRL2 in the immunosuppressive tumour microenvironment in hepatocellular carcinoma.

Introduction: The conflict between cancer cells and the host immune system shapes the immune tumour microenvironment (TME) in hepatocellular carcinoma (HCC). A deep understanding of the heterogeneity and intercellular communication network in the TME of HCC will provide promising strategies to orchestrate the immune system to target and eradicate cancers.

Methods: Here, we performed single-cell RNA sequencing (scRNA-seq) and computational analysis of 35786 unselected single cells from 3 human HCC tumour and 3 matched adjacent samples to elucidate the heterogeneity and intercellular communication network of the TME.

Universal Detection and Imaging for Multiple Targets by Coupling Target-Primed Nicking-Enhanced Rolling Circle Amplification with Self-Powered DNAzyme Walker.

Although promising in monitoring low-abundance analytes, most of the DNAzyme walker is only responsive to a specific target. Herein, a universal, ready-to-use platform is developed by coupling nicking-enhanced rolling circle amplification and a self-powered DNAzyme walker (NERSD). It addressed the issues that DNAzyme strands need to be specifically designed for different biosensing system, allowing highly sensitive analysis of various targets with the same DNAzyme walker components.

Facile construction of photocatalytic cellulose-based sponge with stable flotation properties as efficient and recyclable photocatalysts for sewage treatment.

Dispersion and recycling of powdered nano-photocatalysts for water purification is still not an easy task. The self-supporting and floating photocatalytic cellulose-based sponges ware conveniently prepared by anchoring BiOX nanosheet arrays on cellulose-based sponge's surface. The introduction of sodium alginate into the cellulose-based sponge significantly enhanced the electrostatic adsorption of bismuth oxygen ions and promoted the formation of bismuth oxyhalide (BiOX) crystal nuclei.
