Zone-inspired hydrogel constructs promote spatially controlled chondrogenesis for osteochondral regeneration
In this study, we developed a multilayer hydrogel construct composed of methacrylated chondroitin sulfate (CSMA), gelatin methacryloyl (GelMA), polyethylene glycol dimethacrylate (PEGDMA), and nano-hydroxyapatite (nHA), engineered to replicate the biochemical and biomechanical gradients of the cartilage zones.

Biological Treatment in Meniscus Injury
Meniscal injuries, common in sports, often cause knee pain and instability. The meniscus plays a key role in pressure distribution and joint stability, making its repair essential. Treatments range from conservative approaches to surgical interventions, with growing interest in biological factors such as growth factors, mesenchymal stem cells, platelet-rich plasma, fibrin clot, and tenocyte to enhance healing. This review compares the effects of these biological agents in meniscal repair, examining their mechanisms, limitations, and clinical outcomes.

Does losing weight make an athlete better? Associations between body composition and performance
In endurance sports such as running and cross-country skiing, a lighter body weight can improve relative power generation and reduce energy consumption. However, losing weight requires an energy deficit, which can negatively impact health and performance. Therefore, weight optimization always involves balancing the benefits and risks. In addition to weight, body composition can also impact an athlete's performance.
