Analysis of Three-dimensional Printing Strategies for Meniscus/Articular Disc Repair and Regeneration.

Three-dimensional printing (3DP) strategies in the field of meniscus and articular disc repair and regeneration have recently garnered significant attention. However, a comprehensive bibliometric assessment to evaluate the scientific progress in this area is lacking. This research aims to explore the development, key areas of focus, and new directions in 3DP techniques for meniscus and articular disc over the last 15 years, considering both structural and temporal perspectives.

Research hotspots and trends of mesenchymal stem cell-derived extracellular vesicles for drug delivery: a bibliometric and visualization analysis from 2013 to 2023.

Introduction: Our study aims to provide a comprehensive overview of mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) in drug delivery research, focusing on the period between 2013 and 2023. Given the increasing global interest in this field, we utilized bibliometric tools to explore publication trends, key contributors, and thematic research clusters.

Methods: Data was collected from the Web of Science (WoS) database, and an in-depth bibliometric analysis was conducted using VOSviewer.

Carbon dioxide emissions and environmental risks: Long term and short term.

The world is currently experiencing the environmental challenge of global warming, necessitating careful planning of carbon dioxide (CO ) emissions to deal with this problem. This study examines the environmental challenge posed by CO emissions from both a long and short-term perspective. In the long term, despite efforts made by countries, our change-point detection analysis shows that there has been no structural change in CO emissions since 1950.
