Background: Postoperative swelling is a common complication after total knee arthroplasty (TKA), associated with pain, limited mobility, and delayed recovery. This study aimed to systematically review the literature on interventions that reduce postoperative swelling, categorized into preoperative, intraoperative, and postoperative phases.

Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant search of PubMed, Medline, Embase, and Cochrane databases was performed for clinical studies evaluating interventions to reduce swelling after primary TKA.

Self-Propelled Magnetic Micromotor-Functionalized DNA Tile System for Autonomous Capture of Circulating Tumor Cells in Clinical Diagnostics.

Circulating tumor cells (CTCs) carry intact tumor molecular information, making them invaluable for personalized cancer monitoring. However, conventional capture methods, relying on passive diffusion, suffer from low efficiency due to insufficient collision frequency, severely limiting clinical utility. Herein, a magnetic micromotor-functionalized DNA-array hunter (MMDA hunter) is developed by integrating enzyme-propelled micromotors, magnetic nanoparticles, and nucleic acid aptamers into distinct functional partitions of a DNA tile self-assembly structure.

Despite growing interest in smartphone applications (apps) as tools for eating disorder (ED) intervention, significant challenges remain in optimizing their utility and implementation. Cruz et al. conducted a meta-analysis of 14 trials examining smartphone app-based interventions for EDs, finding apps to effectively reduce numerous symptoms.

This paper presents the results of experimental research on rolling resistance forces occurring during the motion of omnidirectional wheels equipped with dual rows of passive rollers. Due to the complexity of wheel-surface interactions and the stochastic nature of contact transitions, such wheels are often characterized experimentally rather than analytically. A custom-built test stand was used to measure resistance forces for different wheel orientations (0°, 30°, 45°, 60°, and 90°) and two vertical loads (117.
