25. Enxerto sintético e biológico, com e sem preenchimento de veia jugular externa, no reparo de nervo periférico em ratos / Syntetic and biological graft, filled with the external jugular vein in the repair of peripheral nerve in rats
Despite the development of technology involved in peripheral nerve regeneration, there is no technique that presents a recovery of the nervous tissue with completely satisfactory results. This fact arouses interest of several researchers around the word. Although the autologous nerve grafting is the current gold standard for the repair of large nerve gaps, o

26. O uso de células-tronco na regeneração dos tecidos dentários e periodonto / The use of stem cells in regeneration of dental tissues and periodontium
Os estudos abordando a regeneração dos tecidos dentários ganharam uma nova perspectiva com a utilização das células-tronco. E novas perspectivas têm surgido com a bioengenharia tecidual e as terapias periodontais e pulpares regeneradoras. O objetivo deste trabalho foi desenvolver o modelo experimental de autotransplante em ratos visando compará-lo à

27. Expressão do receptor de macrófago com estrutura de colágeno (MARCO) em macrófagos, células dendríticas e células tumorais após internalização de nanotubos de carbono / Expression of macrophage receptor with collagen structure (MARCO) in macrophages, dendritic cells and tumor cells after internalization of carbon nanotubes
The aplication of nanotechnology emerges with potential for application in the biomedical area, pathological diagnosis and treatment, drug transport and intracellular transport of molecules. Among the nanoparticles, carbon nanotubes (NT) belong to a new class of material for application in the biomedical area. Due to its small size, the NT can be internalize

28. Normal skin and hypertrophic scar fibroblasts differentially regulate collagen and fibronectin expression as well as mitochondrial membrane potential in response to basic fibroblast growth factor
Basic fibroblast growth factor (bFGF) regulates skin wound healing; however, the underlying mechanism remains to be defined. In the present study, we determined the effects of bFGF on the regulation of cell growth as well as collagen and fibronectin expression in fibroblasts from normal human skin and from hypertrophic scars. We then explored the involvement

29. Efeitos do veneno de Apis mellifera e do metotrexato sobre peptidases do plasma, do líquido e membrana sinoviais e de leucócitos circulantes em ratos com artrite induzida por colágeno tipo II. / Effects of Apis mellifera venom and methotrexate on plasma, synovial fluid and membrane and circulating leukocytes peptidases in rats with type II collagen- induced arthritis.
Atividades peptidásicas têm sido relacionadas à artrite reumatoide (AR). Os mecanismos de ação do tratamento usual, o metotrexato (MTX), e de terapias alternativos da AR, como a acupuntura com veneno de abelhas (BV), não são completamente compreendidos. Para contribuir com o conhecimento da AR, o presente estudo avaliou parâmetros consagrados para AR

30. Emprego do colageno com organização supramolecular na regeneração nervosa periferica in vitro e in vivo / Influence of a naturally supraorganized collagen on the peripheral nerve regeneration in vitro and in vivo
The present study investigated in vitro and in vivo the influence of naturally supraorganized collagen on the peripheral nerve regeneration. In the in vitro study, Schwann cells (SCs) were seeded on naturally supraorganized collagen membranes and evaluated with immunocytochemistry and scanning electron microscopy. The results revealed that SCs kept the expre

31. Digital subtraction radiographic analysis of the combination of bioabsorbable membrane and bovine morphogenetic protein pool in human periodontal infrabony defects
OBJECTIVES: This study assessed the bone density gain and its relationship with the periodontal clinical parameters in a case series of a regenerative therapy procedure. MATERIAL AND METHODS: Using a split-mouth study design, 10 pairs of infrabony defects from 15 patients were treated with a pool of bovine bone morphogenetic proteins associated with collagen

32. Efeito da finasterida e da doxazosina sobre a próstata de rato : análise ultra-estrutural e da expressão dos colágenos tipo I e III e do TGF-b 1 / Finasteride and doxazosin effects on rat prostate : ultrastructural and type Iand type III and TGF-1 expression analyses
Finasteride and doxazosin are drugs used in the benign prostatic hyperplasia (BPH) treatment and, more recently, they re have been used in the prostate cancer (PCa) chemoprevention, mainly because their apoptotic effect in the prostatic epithelial cells. However, few attentions have been given to the effects of these drugs in the glandular stroma. Thus, the

33. Avaliação clínica e histológica de implantes imediatos e tardios associados a matriz óssea xenógena e membranas: acompanhamento de 10 anos / Clinical and histological evaluation of immediate and late implants associated with xenogeneous bone matrix and membranes: 10 years follow-up
The aim of this research is to evaluate the clinical and histological findings of installed implants immediately after exodontics (Group 1) and later after the alveolus regeneration (Group 2). In both groups, xenogeneous lyophilized bone matrix was used in association with resorbable bovine collagen membrane and/or nonresorbable expanded politetrafluoretane

34. Análise das células inflamatórias e da proteína anexina 1 no modelo de artrite experimental e reumatóide humana. / Analysis of the inflammatory cells and annexin 1 protein in the experimental model arthritis and in the human rheumatoid .
Rheumatoid arthritis (RA) is a disease characterized by auto-antibody formation, chronic inflammation and joint oedema resulting in injury of affected cartilage and adjacent bone. In the treatment of this disease glucocorticoids (GC) have been used, wich induce genic expression of anti-inflammatory mediators, such as the annexin 1 protein (Anx-A1), and proin

35. Collagen XVIII/endostatin expression in experimental endotoxemic acute renal failure
Acute renal failure (ARF) is a frequent complication of Gram-negative sepsis, with a high risk of mortality. Lipopolysaccharide (LPS)-induced ARF is associated with hemodynamic changes that are strongly influenced by the overproduction of nitric oxide (NO) through the cytokine-mediated up-regulation of inducible NO synthase. LPS-induced reductions in systemi

36. Alport syndrome: significance of gingival biopsy in the initial diagnosis and periodontal evaluation after renal transplantation
Alport Syndrome (AS) is an important hereditary disorder affecting the glomerular basement membrane. Diagnosis of AS is based on the presence of hematuric nephropathy, renal failure, hearing loss, ocular abnormalities and changes in the glomerular basement membrane of the lamina densa. The aims of this case report were to show the changes in the gingival tis
