Epstein-Barr virus infection exacerbates ulcerative colitis by driving macrophage pyroptosis via the upregulation of glycolysis.

Background: Epstein-Barr virus (EBV) infection is associated with clinical symptoms, treatment response, need for surgical intervention, and an enhanced likelihood of lymphoma among patients with ulcerative colitis (UC). However, existing studies have primarily concentrated on the epidemiological and clinical associations between EBV and UC, leaving the mechanisms by which EBV exacerbates colitis poorly understood.

Methods: Clinical specimens of UC patients with EBV infection and a mouse model of dextran sulfate sodium-induced colitis with concurrent murine γ-herpesvirus 68 (MHV-68) infection were utilized to investigate the relationship between EBV infection and macrophage pyroptosis.

Intelligent hydrogel and smartphone-assisted colorimetric sensor based on Bi-metallic organic frameworks for effective detection of kanamycin and oxytetracycline.

A smartphone-integrated colorimetric sensor is introduced for the rapid and simultaneous detection of kanamycin (KAN) and oxytetracycline (OTC). This sensor relies on the peroxidase-mimicking activity of Fe/Zr Bi-metallic organic frameworks (UIO-66(Fe/Zr)-NH). This Bi-metallic MOF can facilitate the oxidation of a colorless substrate, 3,3',5,5'-tetramethylbenzidine (TMB), by reactive oxygen species (ROS) derived from hydrogen peroxide (HO), resulting in the formation of blue-colored oxidized TMB (ox-TMB).

S1PR1-biased activation drives the resolution of endothelial dysfunction-associated inflammatory diseases by maintaining endothelial integrity.

G protein-coupled sphingosine-1-phosphate receptor 1 (S1PR1), a drug target for inflammatory bowel disease (IBD), enables immune cells to egress from lymph nodes, but the treatment increases the risk of immunosuppression. The functional signaling pathway triggered by S1PR1 activation in endothelial cells and its therapeutic application remains unclear. Here, we showed that S1PR1 is highly expressed in endothelial cells of IBD patients and positively correlated with endothelial markers.

In order to investigate the basic genetic structure of dysentery in Jingyuan chickens and to explore the genetic markers associated with dysentery resistance in chickens, the present study was based on the genome-wide association analysis (GWAS) technique to investigate the candidate SNPs and genes associated with dysentery resistance in Jingyuan chickens, and a total of 12 SNPs were associated with dysentery resistance in Jingyuan chickens. In addition, some important candidate genes inciuding frizzled class receptor 4 (FZD4), DDB1 and CUL4 associated factor 13(DCAF13), regulating synaptic membrane exocytosis 2 (RIMS2), transmembrane protein 8C (TMEM8C), and RIC1 homolog (RIC1) were identified by selection signal analysis, gene annotation, and enrichment analysis. These results can be used as potential molecular selection markers for chicken dysentery resistance in Jingyuan chickens in order to improve the breeding of disease resistance in Jingyuan chickens.

EMBANet: A flexible efficient multi-branch attention network.

Recent advances in the design of convolutional neural networks have shown that performance can be enhanced by improving the ability to represent multi-scale features. However, most existing methods either focus on designing more sophisticated attention modules, which leads to higher computational costs, or fail to effectively establish long-range channel dependencies, or neglect the extraction and utilization of structural information. This work introduces a novel module, the Multi-Branch Concatenation (MBC), designed to process input tensors and extract multi-scale feature maps.

Influence of nutritional status on rehabilitation efficacy of patients after stroke-a scoping review.

Stroke patients are susceptible to malnutrition as a result of dysphagia, neurological impairments, and altered levels of consciousness. The nutritional status of individuals post-stroke is a critical determinant influencing the efficacy of rehabilitation outcomes. Therefore, there is great interest in the possible role of nutrients in promoting recovery after stroke.

Study on the Friction Behavior and Mechanism of DLC Films in Waxy Oil Extraction Environment Based on Reactive Molecular Dynamics.

Diamond-like carbon (DLC) film is considered a highly promising coating for reducing friction and wear in oil and gas exploitation equipment, owing to its exceptional wear resistance and antifriction properties. Herein, the friction and wear behavior of the Fe-Fe model (conventional steel plunger pump barrel) and the DLC-Fe model (DLC-coated plunger pump barrel) in a waxy oil recovery environment was studied by Molecular dynamics (MD) simulation. The results show that the DLC film can inhibit the lattice evolution of the friction interface and reduce the shear deformation between the friction pairs and the weak interaction between the DLC film and the waxy crude oil system, ultimately reducing the friction and wear.

Host 3' flap endonuclease Mus81 plays a critical role in trimming the terminal redundancy of hepatitis B virus relaxed circular DNA during covalently closed circular DNA formation.

Hepatitis B virus (HBV) relaxed circular DNA (rcDNA) possesses an 8-9 nucleotide-long terminal redundancy (TR, or r) on the negative (-) strand DNA derived from the reverse transcription of viral pregenomic RNA (pgRNA). It remains unclear whether the TR forms a 5' or 3' flap structure on HBV rcDNA and which TR copy is removed during covalently closed circular DNA (cccDNA) formation. To address these questions, a mutant HBV cell line HepDES-C1822G was established with a C1822G mutation in the pgRNA coding sequence, altering the sequence of 3' TR of (-) strand DNA while the 5' TR remained wild type (wt).
