The impact of neighborhood environment on the mental health: evidence from China.

Introduction: The community environment is a significant social determinant affecting individual mental health.

Purpose: This study explores the impact mechanisms and urban-rural heterogeneity in the relationship between socioeconomic status and individual mental health, focusing on community environmental perceptions and neighborhood interactions.

Methods: This study used data from the 2021 Chinese General Social Survey (CGSS), selecting a sample of 1,974 respondents.

Adhesive transparent antimicrobial quaternized chitosan/oxidized dextran/polydopamine nanoparticle hydrogels for accelerated wound healing.

Hydrogels possessing appropriate adhesion and antibacterial properties have emerged as promising dressings for expediting wound healing, while also providing the convenience of visualizing the wound site to accurately monitor the healing process. In this study, we incorporated oxidized and degraded polydopamine nanoparticles into quaternized chitosan/oxidized dextran hydrogel QOP series, resulting in enhanced transmittance exceeding 95 % and adhesion strengths reaching up to 19.4 kPa.

Comprehensive discovery and functional characterization of the noncanonical proteome.

The systematic identification and functional characterization of noncanonical translation products, such as novel peptides, will facilitate the understanding of the human genome and provide new insights into cell biology. Here, we constructed a high-coverage peptide sequencing reference library with 11,668,944 open reading frames and employed an ultrafiltration tandem mass spectrometry assay to identify novel peptides. Through these methods, we discovered 8945 previously unannotated peptides from normal gastric tissues, gastric cancer tissues and cell lines, nearly half of which were derived from noncoding RNAs.
