Introduction: Immunotherapy, especially immune checkpoint blockade (ICB), holds promise as a therapeutic strategy in colorectal cancer (CRC) by harnessing the patient's immune system to target malignant cells. Particularly, the PD-1/PD-L1 axis is widely recognized for its critical role in tumor microenvironment immunosuppression. Antibodies targeting PD-1 or PD-L1 have shown sustained efficacy against various cancers, including CRC.

Article Synopsis
  • The study investigates the impact of metabolic dysfunction-associated steatotic liver disease (MASLD) on significant fibrosis in patients with chronic hepatitis B (CHB), aiming to determine if those with both conditions face a higher risk.
  • A total of 1818 patients were analyzed, revealing that those with CHB and MASLD exhibited significant fibrosis at rates of 35.5%, compared to 23.5% in those with just CHB.
  • The findings suggest that MASLD is linked to increased fibrosis in CHB patients, especially for those with three or more cardiometabolic risk factors, highlighting the importance of early detection and intervention.

Article Synopsis
  • The study analyzed the interface adhesion work in three terminal systems involving CrAlSiN and WC-Co, finding that the CrAlSiN/WC-Co model had the highest adhesion work, indicating better bonding properties, while the others had lower values.
  • Rare earth oxides CeO and YO were then introduced into the Al terminal model, leading to the construction of doping models for various interfaces, where doping with CeO and YO generally reduced adhesion work in the WC/WC and CrAlSiN/WC-Co interfaces but improved it in the WC/Co interface.
  • The study also examined charge density differences and bond populations, revealing that doping with YO resulted in stronger atomic interactions and improved bonding strength at the interface compared to CeO

A double-coil inductive displacement transducer is a non-contact element for measuring displacement and is widely used in large power equipment systems such as construction machinery and agricultural machinery equipment. The type of coil excitation signal has an impact on the performance of the transducer, but there is little research on this. Therefore, the influence of the coil excitation signal on transducer performance is investigated.

A dual-coil inductive displacement transducer is a non-contact type measuring element for measuring displacement and is widely used in large power equipment systems such as construction machinery and agricultural equipment. However, the effect of the coil excitation method on the performance of dual-coil inductive displacement sensors has not been studied. This paper investigates the impact of different coil excitation methods on the operating performance of displacement transducers.

Article Synopsis
  • The study investigates the interface properties of TiAlSiN/WC-Co models with graphene integrated into various layers using a first-principles method to enhance bonding characteristics.
  • Results indicate that doping the matrix with intrinsic graphene improves the adhesion strength, while doping the coating or coating/matrix separately also yields better bonding properties.
  • Strong covalent bonds (Si/Co and N/Co) and increased charge transfer in these interfaces contribute to higher adhesion work, demonstrating that graphene doping significantly enhances the material interface performance.

As an important artificial implant material, the corrosion resistance of NiTi shape memory alloy is closely related to the machined surface quality. In this paper, the multiple analysis methods concerning potentiodynamic polarization, impedance spectrum and corrosion morphology are used to analyze the corrosion resistance of the alloy. The potentiodynamic polarization and impedance spectrum test results show that the conductivity and corrosion current density of electrochemical polishing surface decrease, and the polarization resistance and corrosion potential increase compared with milling.

An axially chiral indolyl-pyrroloindole scaffold, a new member of axially chiral indole-based scaffolds, has been designed, and the catalytic asymmetric construction of this scaffold has been established by the strategy of organocatalytic asymmetric (2 + 3) cycloaddition of 3,3'-bisindoles with isoindolinone-based propargylic alcohols. By this approach, a series of indolyl-pyrroloindole derivatives bearing both axial chirality and central chirality were synthesized in high yields with excellent diastereo- and enantioselectivities (up to 95% yield, 91:9 dr, 99% ee). This reaction not only realizes the first catalytic asymmetric (2 + ) cycloaddition of 3,3'-bisindoles as 1,2-dinucleophiles but also provides a new strategy for atroposelective construction of axially chiral indole-based scaffolds bearing five-five-membered rings, thus solving the challenges in constructing this class of axially chiral indole-based scaffolds.

Background And Aims: Collagen β(1-O) galactosyltransferase 25 domain 1 (GLT25D1) is associated with collagen production and glycosylation, and its knockout in mice results in embryonic death. However, its role in liver fibrosis remains elusive, particularly in hepatic stellate cells (HSCs), the primary collagen-producing cells associated with liver fibrogenesis. Herein, we aimed to elucidate the role of GLT25D1 in HSCs.

Background: A preliminary study by our group revealed that the deficiency of EGF domain-specific O-linked N-acetylglucosamine transferase (EOGT) impaired regulatory T-cell differentiation in autoimmune hepatitis. Nevertheless, the prognostic value of EOGT in advanced hepatocellular carcinoma (HCC) and its relationship with immune infiltration remain obscured.

Methods: Initially, EOGT expression was evaluated by Oncomine, TIMER, GEO, and UALCAN databases.

Even though numerous studies have shown that adolescent empathy is positively related to bystander defending in school bullying, others have failed to detect a significant association between these two variables. To address this discrepancy, a three-level meta-analysis of 27 papers (35 independent studies, = 25,012 adolescents) was conducted. The results showed that empathy was positively correlated with bystander defending.

Background: Endoplasmic reticulum (ER) stress is one of the major causes to the pathogenesis of nonalcoholic fatty liver disease (NAFLD). Our previous study showed that maintains the homeostasis of ER could effectively alleviate NAFLD. In this study, we found that the loss of FAM172A increased ER stress.

Post-translational modifications such as glycosylation play an important role in the functions of homeostatic proteins, and are critical driving factors of several diseases; however, the role of glycosylation in autoimmune hepatitis is poorly understood. Here, we established an O-GlcNAc glycosylation-deficient rat model by knocking out the gene by TALEN-mediated gene targeting. O-GlcNAc glycosylation deficiency overtly aggravated liver injury in concanavalin-A induced autoimmune hepatitis, and delayed self-recovery of the liver.
