: Patient-specific instrumentation (PSI) in total knee arthroplasty (TKA) uses preoperative three-dimensional imaging to create cutting blocks tailored to patient anatomy. However, there is debate regarding the additional benefits of PSI in terms of improved alignment or functional outcomes compared to using conventional instruments. Although PSI design has undergone continuous development, the improvements have not been incorporated.

Here we evaluated a nationwide capacity of natural purification in tidal flats. Using in situ sediments from five along the Korean coast (Incheon, Gunsan, Sinan, Gwangyang, and Busan), we applied a mesocosm system informed by 18 years of riverine monitoring data from national surveys.

This study investigated ultrasound-assisted enzymatic hydrolysis (UAEH) of ZMP using different enzymes (Alcalase, Neutrase, and Protamex) to determine its effect on the degree of hydrolysis (DH) compared to enzymatic hydrolysis (EH). UAEH showed greater hydrolysis efficiency than EH, with Alcalase exhibiting the highest DH.
