The development of biomimetic scaffolds for osteochondral tissue engineering
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2020)Articular cartilage (AC) is a soft tissue lining the ends of the bones in our joints. Even minor lesions in AC cause pain, impaired mobility and can develop to osteoarthritis (OA), a disease affecting millions of adults ... -
Development and characterization of corneal substitutes from decellularized tissues
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2020)Diseases affecting the cornea can lead to vision impairment and ultimately to blindness. It is estimated that 45 million people worldwide suffer from corneal blindness. Rejection in high-risk patients and donor shortage ... -
Objective and Quantitative acoustic-analysis of musicians dystonia
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2020)Musician s Dystonia (MD) is the most common movement disorder affecting musicians. Being a specific phenotype of Dystonia, MD is a focal, task-specific and painless disorder that affects motor control during musical ... -
3D bioprinting of cartilage-mimetic implants for biological joint resurfacing
