Osteoarthritis (OA) is a degenerative joint disorder resulting in destruction of articular cartilage, osteophyte formation, and subchondral bone sclerosis. In recent years, numerous genetic factors have been identified and implicated in causing osteoarthritis. One such genetic defect is a single nucleotide polymorphism at position -1612 of matrix metalloproteinase-3 (MMP-3) promoter ...

Encapsulation of autologous adult cartilage cells (chondrocytes) in hydrolytically degradable hydrogels may provide a clinically viable tissue engineering therapy for replacement of damaged or osteoarthritic cartilage. When designing a tissue engineering scaffold, it is crucial to evaluate adult chondrocytes due to their limited growth potential. The objective for this study ...

Brain-computer interfaces (BCI) are designed to enable individuals with severe motor impairments such as amyotrophic lateral sclerosis (ALS) to communicate and control their environment.
