It consists of approximately 5% elastin, an extensible tissue that is primarily made up of the amino acids glycine, valine, alanine, and proline.Metallosis: Metallosis is the putative medical condition involving deposition and build-up of metal debris in the soft tissues of the body.Robot-assisted double heart valve replacement: The first robotic-assisted double heart valve replacement was carried out in the Chennai region of India at Chettinad Hospital. Considered a rare form of surgery, this is the first instance of such a procedure using robotic surgery.Photovoltaic retinal prosthesis: Photovoltaic retinal prosthesis is a technology for restoring sight to blind patients suffering from degenerative retinal diseases. In retinal degenerative diseases such as Retinitis Pigmentosa and Age-Related Macular Degeneration, patients loss ‘image capturing’ photo-receptors, but, neurons in the ‘image-processing’ inner retinal layers are relatively well preserved.Utkal Prantiya Marwari Yuva ManchRunning room (dentistry): In implant dentistry, running room refers to the apico-coronal distance between the platform of a dental implant and the gingival margin. It is a critical factor in restorative implant dentistry because it is effectively the "vertical distance [available subgingivaly] to make a transition from the smaller diameter prosthetic platform of an implant to the larger cross-sectional cervical shape of the tooth being restored.George Allan HancockKurt KossmannJoint replacementThomas Girdlestone: Thomas Girdlestone (Holt, Norfolk, 1758 – 25 June 1822) was an English physician and writer.Opacifier: An opacifier is a substance added to a material in order to make the ensuing system opaque.
