Organic ultraviolet filters in Hainan Coral Reefs: Distribution, Accumulation, and Ecological Risks.

Organic ultraviolet filters (OUVFs) have been widely used as functional ingredients of sunscreen products and have entered into marine ecosystems, particularly in tropical areas where solar UV radiation is strong. These chemicals, with their potential toxicity and ecological risk, have raised widespread concern for the protection of the fragile marine ecosystem of coral reefs. In this study, fourteen OUVFs were analyzed among 24 coral species, together with their habitats including seawater and sediment from the coastal coral reef regions of Hainan Island, South China Sea.

Elucidating the molecular mechanisms of CCR5-containing extracellular vesicles in vitro and in a rat model of experimental Rheumatoid arthritis.

Extracellular vesicles from Rheumatoid arthritis (RA) derived synovial fibroblasts (EVs) have been implicated in the pathogenesis of RA, acting as mediators of cell-to-cell communication. This study aimed to elucidate the role of the chemokine receptor CCR5 and EVs positive for CCR5 (EVs) in RA, focusing on their impact on cartilage destruction and bone erosion in a rat model of Adjuvant-induced arthritis (AIA). In vivo experiments were conducted using AIA rats, treated with either EVs, EVs without CCR5 (EVs), or EVs which encapsulated the CCR5 antagonist Maraviroc.

Non-Pharmacological Therapies for Post-Stroke Spastic Paralysis: A Bibliometric Analysis of Global Research from 2000 to 2024.

Objective: This study aims to explore the research landscape, hot topics, and future trends of non-pharmacological therapies for post-stroke spastic paralysis globally from 2000 to 2024 through a bibliometric analysis.

Methods: We conducted a search in the Web of Science Core Collection database to analyze literature related to non-pharmacological therapies for post-stroke spastic paralysis published between 2000 and 2024. Tools including CiteSpace, VOSviewer, Bibliometrix, Scimago, and R language were used to identify and analyze countries, institutions, journals, references, keywords, as well as the most commonly used therapies and acupuncture points.

The current situation and associated factors of preoperative frailty in elderly patients undergoing abdominal surgery.

Background: This study aimed to investigate the current preoperative frailty status of elderly patients undergoing abdominal surgery and identify its associated factors. The objective of this study was to provide clinicians with valuable insights for implementing frailty intervention strategies.

Methods: A cross-sectional study was conducted with 375 elderly patients who underwent abdominal surgery at a tertiary hospital in Chengdu, Sichuan Province, between October 2021 and August 2022.
