UNLABELLED Several materials have been injected or introduced in the vocal folds in attempt of solving the glottic insufficiency. However, few studies have evaluated the cicatricial process due to the implantation of these materials. AIM The objective of this research was to evaluate the concentration of collagen after microsurgery graft of muscular fascia and fat in the vocal folds of rabbit...

PURPOSE The objective of this study was to clinically evaluate the use of OSTEON as a sinus graft material and to measure the effect of healing at 4 and 6 months after surgery. MATERIALS AND METHODS After sinus graft using OSTEON in 17 patients, bone specimens were collected from lateral sinus using 2.0-mm trephine bur at the time of 4 or 6 months after surgery. Histology of the bone specimen...

Objective Sinus floor elevation with lateral approach is probably the most frequently performed reconstructive procedure to rehabilitate posterior maxilla when a bone deficiency is present. Different graft materials have been proposed and tested, often with high clinical performances and predictable results. Histological analysis is required when evaluating new materials. We investigated human ...

MATERIALS AND METHODS: We report on our treatment of 6 limbs in 3 patients (age range, 19–36 years). In each case we applied fat graft at the medial side of the limb 150–175 cc. There were minimal deformity (Langenskiöld stage 1), patients had only aesthetic complaint, not pain or osteoartrit.The varus angulation at the tibia was measured and osteoarthritis was evaluated with radiographs.Patien...

An efficient procedure to produce polyethene–graft–polystyrene (E-C3–graft–PS) copolymers by simple thermal treatment at 200 1C of polyethene (PE)-containing cyclopropane ring units (E-C3) in the presence of a high excess of styrene is reported. The high treatment temperature likely induces the breaking of the constrained cyclopropane rings, leading to the formation of radicals on the PE chains...

BACKGROUND AND PURPOSE Cerebral bypass grafts may develop generalized graft narrowing or focal stenosis during the perioperative period or later. Endovascular techniques such as PTA and stent placement of graft vessels are potential treatment options. Our objective was to review the safety, indications, technique, and results of endovascular management of graft problems. MATERIALS AND METHODS...

Polylactic acid (PLA) has found widespread use in plastics and in biomedical applications due to its biodegradability into natural benign products. However, PLA-based materials remain limited in usefulness due to difficulty of incorporating functional groups into the polymer backbone. In this paper, we report a strategy for PLA functionalization that establishes the preparation of highly deriva...

Materials and Methods: The graft materials were assessed for bone healing efficacy in the athymic rat posterolateral fusion (PLF) model. This model has been extensively characterized to ensure that there are not instances of spontaneous fusion, and instead that the fusion results from the osteogenic, osteoconductive and/or osteoinductive nature of the graft materials. The transverse processes o...

Introduction: Mucogingival surgery is performed to correct defects in the morphology, position, and/or amount of gingiva. Such post-operative complications as bleeding, swelling, and pain have often been documented after mucogingival surgery and are associated with discomfort after surgery. The low-intensity laser has been used to promote analgesia. Low level laser therapy (LLLT) not only accel...

Introduction: Post-transplantation proteinuria is a risk factor for graft failure. A progressive decline in renal graft function is a predictor for mortality in kidney transplant patients. Objectives: To assess the development and the progression of urinary protein excretion (UPE) in the first year post-transplant in recipients of kidney transplants and its effect on patient and graft outcomes....
