Deciphering the pseudouridine nucleobase modification in human diseases: From molecular mechanisms to clinical perspectives.

RNA pseudouridylation, a dynamic and reversible post-transcriptional modification found in diverse RNA species, is crucial for various biological processes, including tRNA homeostasis, tRNA transport, translation initiation regulation, pre-mRNA splicing, enhancement of mRNA translation, and translational fidelity. Disruption of pseudouridylation impairs cellular homeostasis, contributing to pathological alterations. Recent studies have highlighted its regulatory role in human diseases, particularly in tumourigenesis.

Gastric Cancer Models Developed via GelMA 3D Bioprinting Accurately Mimic Cancer Hallmarks, Tumor Microenvironment Features, and Drug Responses.

Current in vitro models for gastric cancer research, such as 2D cell cultures and organoid systems, often fail to replicate the complex extracellular matrix (ECM) found in vivo. For the first time, this study utilizes a gelatin methacryloyl (GelMA) hydrogel, a biomimetic ECM-like material, in 3D bioprinting to construct a physiologically relevant gastric cancer model. GelMA's tunable mechanical properties allow for the precise manipulation of cellular behavior within physiological ranges.

Factors Associated With Minority Patient Enrollment in a Gastric Cancer Biobank.

Introduction: Human tissue samples are essential for translational cancer research. However, less than 20% of current biobank and genomic samples were obtained from minority patients, which may lead to biased understanding of cancer biology. The objective of this study was to identify factors associated with patient enrollment in our institution's gastric cancer biobank.

Tailoring the Porous Structure of Carbon for Enhanced Oxidative Cleavage and Esterification of C(CO)-C Bonds.

The cleavage and functionalization of carbon-carbon bonds are crucial for the reconstruction and upgrading of organic matrices, particularly in the valorization of biomass, plastics, and fossil resources. However, the inherent kinetic inertness and thermodynamic stability of C-C σ bonds make this process challenging. Herein, we fabricated a glucose-derived defect-rich hierarchical porous carbon as a heterogeneous catalyst for the oxidative cleavage and esterification of C(CO)-C bonds.

A randomized prospective study to compare the efficacy of 308-nm light-emitting diode and 308-nm excimer lamp in the treatment of facial vitiligo.

Background: Previous studies have proven that 308-nm light-emitting diode(308-nm LED)and 308-nm excimer lamp(308-nm MEL) are effective in treating vitiligo, but there is a lack of comparison of their efficacy for facial lesions.

Objective: To evaluate and contrast the treatment success rates of 308-nm LED versus 308-nm excimer lamp in managing facial lesions among patients suffering from stable non-segmental vitiligo.

Methods: The enrolled 119 patients with 145 lesions were randomly assigned to receive 308-nm LED or 308-nm MEL for two months.
