Studies on the effect of curcumin/PLGA ratio (CPR), stabilizer (PVA) concentration, homogenization speed, homogenization time, and sonication time on mean particle size (MPS) and percentage drug encapsulation (PDE) were performed using the multivariate technique. MPS and PDE were found to be more dependent on the interaction of sonication time with the other variables. Curcumin was released in a sustained manner from curcumin-PLGA nanoparticles (CPN). CPN improved the survival rate of Ehrlich ascites carcinoma (EAC)-bearing mice and controlled the EAC-induced change in hematological parameters. Histopathology of vital organs showed that the formulation was safe. Polycaprolactone was used in preparing an in situ implant containing CPN.

In situ bone regeneration and vertical bone augmentation have been huge problems in clinical practice, always imposing a significant economic burden and causing patient suffering. Herein, MgZnYNd magnesium alloy rod implantation in mouse femur resulted in substantial subperiosteal new bone formation, with osteoimmunomodulation playing a pivotal role. Abundant macrophages were attracted to the subperiosteal new bone region and proved to be the most important regulation cells for bone regeneration.

Novel ferrite/polyurethane nanocomposites were synthesized using the in situ polymerization method after the addition of different spinel nanoferrite particles (copper, zinc, and copper-zinc) and examined as potential coatings for medical devices and implants in vascular tissue engineering. The influence of the nanoferrite type on the structure and functional characteristics of the polyurethane composites was investigated by FTIR, SWAXS, AFM, TGA, DSC, nanoindentation, swelling behavior, water contact angle, and water absorption measurements. Biocompatibility was evaluated by examining the cytotoxicity and adhesion of human endothelial cells and fibroblasts onto prepared composites and performing a protein adsorption test.

Articular cartilage has a limited self-healing capacity, leading to joint degeneration and osteoarthritis over time. Therefore, bioactive scaffolds are gaining attention as a promising approach to regenerating and repairing damaged articular cartilage through tissue engineering. In this study, we reported on a novel 3D bio-printed proteinaceous bioactive scaffolds combined with natural porcine cancellous bone dECM, tempo-oxidized cellulose nanofiber (TOCN), and alginate carriers for TGF-β1, FGF-18, and ADSCs to repair cartilage defects.
