Dissolution, bioactivity behavior, and cytotoxicity of 19.58Li O·11.10ZrO ·69.32SiO glass-ceramic.

Glass and bioactive glass-ceramic can be used in several applications. In bone growth where good bone/biomaterial adhesion was required, bioactive coatings for implants can improve bone formation. The glass and glass-ceramics of the LZS (Li O-ZrO -SiO ) system are very interesting because of their mechanical, electrical, and thermal properties.

Polydimethylsiloxane/nano calcium phosphate composite tracheal stents: Mechanical and physiological properties.

In this study, we report the production and characterization of tracheal stents composed of polydimethylsiloxane/nanostructured calcium phosphate composites obtained by reactive synthesis. Tracheal stents were produced by transfer molding, and in vivo tests were carried out. PDMS was combined with H PO and Ca(OH) via an in situ reaction to obtain nanoparticles of calcium phosphate dispersed within the polymeric matrix.

Fiber-reinforced silicone for tracheobronchial stents: An experimental study.

A trachea is a tubular structure composed of smooth muscle that is reinforced with cartilage rings. Some diseases can cause sagging in smooth muscle and cartilaginous tissue. The end result is reduction (narrowing) of the trachea diameter.
