A comparative analysis of 3D bioprinted gelatin-hyaluronic acid-alginate scaffold and microfracture for the management of osteochondral defects in the rabbit knee joint.

Objectives: This study aims to compare the radiological, biomechanical, and histopathological results of microfracture treatment and osteochondral damage repair treatment with a new scaffold product produced by the three-dimensional (3D) bioprinting method containing gelatin-hyaluronic acid-alginate in rabbits with osteochondral damage.

Materials And Methods: A new 3D bioprinted scaffold consisting of gelatin, hyaluronic acid, and alginate designed by us was implanted into the osteochondral defect created in the femoral trochlea of 10 rabbits. By randomization, it was determined which side of 10 rabbits would be repaired with a 3D bioprinted scaffold, and microfracture treatment was applied to the other knees of the rabbits.

Propolis-Based Nanofiber Patches to Repair Corneal Microbial Keratitis.

In this research, polyvinyl-alcohol (PVA)/gelatin (GEL)/propolis (Ps) biocompatible nanofiber patches were fabricated via electrospinning technique. The controlled release of Propolis, surface wettability behaviors, antimicrobial activities against the and , and biocompatibility properties with the mesenchymal stem cells (MSCs) were investigated in detail. By adding 0.

A Comparison of Incremental Running Field and Treadmill Tests in Young Soccer Players.

The purpose of this study was to compare the incremental running tests performed by young soccer players on a treadmill (Tr) and in the field (FT: 100 m change of direction and FT: 100 m circle). Nineteen players (average age 17.4 ± 1.
