In Dentistry, the search for positive changes in aesthetics of smile has been increasing and with that objectives have become broader, not being restricted only to teeth, but also treating both functional aesthetic parts face, known as Orofacial Harmonization. With aging, tissue loss aggravation resulting from effects gravity, it is observed atrophy region lips erasure philtrum region, inversio...

OBJECTIVE to analyze the effects of hyaluronic acid of different molecular weights in an experimental model of osteoarthritis in rabbits. METHODS forty-four male California rabbits were divided randomly into three groups and underwent resection of the anterior cruciate ligament in his right knee. After three weeks of the surgical procedure began three weekly intra-articular injections of hyal...

A deep burn wound is a critical condition that generally necessitates vascularized tissue coverage. We performed the injection of platelet-derived factor concentrates combined with non-cross-linked hyaluronic acid scaffolds for 2 patients with critical burn wounds with bone and tendon exposure and achieved successful healing. Hyaluronic acid was considered to have served as a controlled-release...

Hyaluronic acid (Healon), oxycellulose (hydroxypropyl methylcellulose), and glycerin are lubricants used in cochlear implant surgery for atraumatic deep insertion of the electrode array into the scala tympani. The electrical impedances of these three lubricants were measured to assess possible effects on intraoperative evoked response measurements, such as the electrically evoked stapedius refl...

In this work we develop a field-theoretic methodology, which combines the concept of Gaussian equivalent representation for functional integrals with the continuous Gaussian thread model of flexible polymers for solving statistical-mechanical problems of polyelectrolyte solutions. We demonstrate the applicability of the method for systems of polyelectrolyte chains where the monomers interact vi...
