Current understanding and prospects for targeting neurogenesis in the treatment of cognitive impairment.

Adult hippocampal neurogenesis is linked to memory formation In the adult brain, with new neurons in the hippocampus exhibiting greater plasticity during their immature stages compared to mature neurons. Abnormal adult hippocampal neurogenesis is closely associated with cognitive impairment in central nervous system diseases. Targeting and regulating adult hippocampal neurogenesis have been shown to improve cognitive deficits.

Effects of air pollution on the development and progression of digestive diseases: an umbrella review of systematic reviews and meta-analyses.

Air pollution, especially particulate matter (PM), is one of the most common risk factors for global burden of disease. However, its effect on the risk of digestive diseases is unclear. Herein, we attempt to explore this issue by reviewing the existing evidence from published meta-analyses.

Parent-child relationship and junior high academic performance: Differentiated impacts of fathers and mothers with self - efficacy as a mediator.

This study aimed to address the overlooked differences in the effects of father-child and mother-child relationships on junior high school students' academic performance. Utilizing data from the China Education Panel Survey, it explored these relationships' impacts on overall and subject-specific academic achievements and the mediating role of self-efficacy. Findings revealed both relationships had positive effects, with the mother-child relationship being more prominent.

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.
