Mechanisms Underlying Delayed loss of HBeAg and HBV DNA Following HBsAg Seroclearance in PEG-IFNα Treated Patients of chronic hepatitis B.

Background & Aims: A notable proportion of CHB patients undergoing PEG-IFNα based therapy experience lagged serum HBeAg and/or HBV DNA disappearance in patients achieving HBsAg loss. In this study, we explored the molecular mechanisms behind this clinical phenomenon, offering novel insights into the sustainability of chronic HBV infection.

Methods: Two independent clinical cohorts were enrolled to validate this phenomenon.

Intrinsic STING of CD8 + T cells regulates self-metabolic reprogramming and memory to exert anti-tumor effects.

Background: Our team has previously found that the stimulator of interferon genes (STING) plays a more significant anti-tumor role in host immune cells than in tumor cells. Although STING is necessary for CD8 + T cells to exert immunological activity, its effect on CD8 + T cells remains debatable. In this study, we used both in vitro and in vivo models to explore the metabolic effects of STING on CD8 + T cells.

Single-cell sequencing of peripheral blood mononuclear cells reveals immune landscape of monkeypox patients with HIV.

The monkeypox (MPXV) outbreak in 2022 is more prevalent among individuals with human immunodeficiency virus (HIV). While it is plausible that HIV-induced immunosuppression could result in a more severe progression, the exact mechanisms remain undetermined. To better understand the immunopathology of MPXV in patients with and without HIV infection, we employed single-cell RNA sequencing (scRNA-seq) to analyse peripheral blood mononuclear cells (PBMCs) from six patients hospitalized for MPXV, three of whom had HIV infection (HIV antibody positive and HIV RNA level below the detection limit), and three patients only infected with MPXV (HIV-).

Assessment and analysis of motor-free visual perception abilities among children aged 5-12 years in Xuzhou, China.

Motor-free visual perception abilities are important reference indicator for children's literacy skills. In the absence of Chinese norms, this study utilized the motor-free visual perception test-4 (MVPT-4) to assess the visual perception abilities of children aged 5-12 years in Xuzhou, China, to lay the foundation for establishing standardized norms in China. From May to July 2023, a stratified random sampling method was used to conduct MVPT-4 evaluation on 525 kindergarten and primary school children in Xuzhou, China.

A Bayesian joint model for mediation analysis with matrix-valued mediators.

Unscheduled treatment interruptions may lead to reduced quality of care in radiation therapy (RT). Identifying the RT prescription dose effects on the outcome of treatment interruptions, mediated through doses distributed into different organs at risk (OARs), can inform future treatment planning. The radiation exposure to OARs can be summarized by a matrix of dose-volume histograms (DVH) for each patient.

Language in job advertisements and the reproduction of labor force gender and racial segregation.

Job advertisements (ads) represent the first point of contact between employers and job seekers. By signaling characteristics expected of an ideal candidate, job ads "gatekeep" the labor force and configure its composition. Meanwhile, labor force composition can also shape the wording of job ads.

What can be observed in intervertebral cartilage endplate with aging? An animal model study of excessive axial mechanical loading.

Introduction: The cartilage endplate (CEP) plays a crucial role as both a mechanical barrier and nutrient channel for the intervertebral disc, but it is vulnerable to excessive axial loading. We modified the Ilizarov external fixator and applied it to the CEP of the rat tail to impose diurnal, controllable excess axial loading. The objective was to measure morphological changes in the CEP when subjected to loading during the aging process.

Progressive transcriptomic shifts in evolved yeast strains following gene knockout.

Gene knockout disrupts cellular homeostasis, altering gene expression, and phenotypes. We investigated whether cells return to their pre-knockout transcriptomic state through adaptive evolution experiments on and yeast strains. Analysis revealed that genes with higher expression levels and more physical interaction partners in wild-type strains were more likely to be restored, suggesting that genes of significant functional importance have increased resilience to genetic perturbations.

Orbital-selective effect of spin reorientation on the Dirac fermions in a non-charge-ordered kagome ferromagnet FeGe.

Kagome magnets provide a fascinating platform for the realization of correlated topological quantum phases under various magnetic ground states. However, the effect of the magnetic spin configurations on the characteristic electronic structure of the kagome-lattice layer remains elusive. Here, utilizing angle-resolved photoemission spectroscopy and density functional theory calculations, we report the spectroscopic evidence for the spin-reorientation effect of a kagome ferromagnet FeGe, which is composed solely of kagome planes.

Screening and identification of microRNAs mediating cartilage endplate degeneration in human intervertebral disks.

Objective: This study aimed to discover micro-ribonucleic acids (microRNAs) involved in the degeneration of cartilage endplates through next-generation sequencing and lay the foundation for further research.

Methods: The cartilage endplate was obtained from patients who underwent interbody fusion surgery at the Department of Spine Surgery, Shanghai East Hospital Affiliated to Tongji University, from 1 January 2020 to 1 January 2023. Total RNA was extracted from the cartilage endplate tissue.

Dual-Mode Reconfigurable Split-Gate Logic Transistor through Van der Waals Integration.

As silicon-based transistors approach their physical size limitations, two-dimensional material-based reconfigurable functional electronic devices are considered the most promising novel device architectures beyond Moore strategies. While these devices have garnered significant attention, they often require complex device fabrication processes and extra electric fields. Additionally, the device performance is usually limited by the metal-semiconductor interface properties.
