13. Combined therapy with mineral trioxide aggregate, and guided tissue regeneration for a large radicular cyst: a 13-year follow-up
Biomaterials such as membrane barriers and/or bone grafts are often used to enhance periapical new bone formation. A combination of apical surgery and these biomaterials is one of the latest treatment options for avoiding tooth extraction. In case of periapical lesions, guided tissue regeneration (GTR) is attempted to improve the self-regenerative healing pr

14. Phase I clinical trial of cell therapy in patients with advanced chronic obstructive pulmonary disease: follow-up of up to 3 years
BACKGROUND Chronic obstructive pulmonary disease is a major inflammatory disease of the airways and an enormous therapeutic challenge. Within the spectrum of chronic obstructive pulmonary disease, pulmonary emphysema is characterized by the destruction of the alveolar walls with an increase in the air spaces distal to the terminal bronchioles but without si

15. Scaffolds baseados em nanopartículas de fosfatos de cálcio para engenharia tecidual óssea / Scaffolds based on calcium phosphate nanoparticles for bone tissue engineering
Tissue engineering associated with nanotechnology stood out because of its multidisciplinarity and results, in addition to targeting many areas of study in the field of regenerative medicine. For the process of bone regeneration to occur in appropriate form, the injured area must be organized. The reorganization of the 3D structure in the affected area shoul

16. Mecanismos envolvidos na resposta imune e inflamatória frente à implantação de membrana de cortical óssea bovina no tecido subcutâneo de camundongos: caracterização histomorfométrica, imunoenzimática e molecular / Mechanisms involved in immune and inflammatory response to implantation of bovine bone cortical membrane in subcutaneous tissue of mice: characterization histomorphometric, imunoenzimatic and molecular
Advances related to the biomaterials science and tissue engineering seek to clarify the mechanisms involved in the biological response associated with the use of those devices and their interaction with the immune system. This study evaluated the inflammatory and immune response developed in mice after implantation bovine bone cortical membrane in subcutaneo

18. Células mononucleares autólogas de medula óssea na regeneração do nervo tibial em coelhos / Autologous mononuclear cells from bone marrow in the regeneration of tibial nerve in rabbits
The regeneration of peripheral nerves after injury has been target in researches for new technologies that lead to good results, so as to get completely restoration of nerve function. For such, many techniques have been developed using synthetic materials associated to exogenous factors that enhance the regeneration process, as mononuclear cells of bone marr

19. Alterations of morphology, mechanical and osteogenic capacity of mdx mice bones / Alterações da morfologia, resistência mecânica e capacidade osteogênica dos ossos de camundongos mdx
Duchenne muscular dystrophy (DMD) is a neuromuscular disease caused by lack of dystrophin. DMD patients have brittle bones because of muscle weakness and use of glucocorticoids. The mdx mouse is widely used as experimental model for the study of DMD and it presents lack of dystrophin, intense inflammatory process and muscle fiber degeneration. Moreover, it p

20. Bone regeneration in surgically created defects filled with autogenous bone: an epifluorescence microscopy analysis in rats
Although the search for the ideal bone substitute has been the focus of a large number of studies, autogenous bone is still the gold standard for the filling of defects caused by pathologies and traumas, and mainly, for alveolar ridge reconstruction, allowing the titanium implants installation. OBJECTIVES: The aim of this study was to evaluate the dynamics o

23. Treatment of gingival recession with collagen membrane and DFDBA: a histometric study in dogs
In a previous study, we evaluated the findings related to the use of resorbable collagen membranes in humans along with DFDBA (demineralized freeze-dried bone allograft). The aim of this subsequent study was to histometrically evaluate in dogs, the healing response of gingival recessions treated with collagen membrane + DFDBA (Guided Tissue Regeneration, GTR

24. Osseointegração de implantes em defeitos circunferenciais utilizando proteínas angiogênicas purificadas do látex, osso autógeno e regeneração óssea guiada. Estudo comparativo em mandíbulas de cães / Implant osseointegration in circumferential bone defects using latexderived proteins, autogenous bone graft and guided bone regeneration. A comparative study in the dog mandible
The development of biomaterials that can assist osseointegration and implant stability in dissatisfactory anatomical regions has been the goal of several researches in the past years. Despite the array of regenerative therapies to be used, some clinical disadvantages still persist, such as considerable patient morbidity, extended patient recovery periods, su
