Although biofilms are formed on a variety of surfaces, of utmost significance are those formed on prosthetic devices used as implants. Such biofilms can lead to severe device-related infections that are difficult to treat. In a search for new antibiofilm agents that can be used as "active" implant coatings, purified fraction from a tannin-rich extract of Terminalia chebula was isolated and tested for its antibiofilm properties on a titanium implant material.
Covalent modifications of titanium with small molecules known to promote human osteoblast maturation are especially attractive in developing superior biomaterials. An important step in securing competent bone formation at implant sites is promoting the formation of mature osteoblasts, either from committed pre-osteoblasts or from their mesenchymal progenitors.

OBJECTIVE: This is the last article in a series of 3 articles introducing a new animal model, the external link model (ELM), that permits reversible, nontraumatic control of the cardinal biomechanical features of the subluxation: fixation and misalignment. A detailed description of current ELM procedures is presented and practical issues are reviewed such as expense (dollars and time) and construct failure rates during and after the surgical implant procedure.
