13. STGC3 inhibits xenograft tumor growth of nasopharyngeal carcinoma cells by altering the expression of proteins associated with apoptosis
STGC3 is a potential tumor suppressor that inhibits the growth of the nasopharyngeal carcinoma cell line CNE2; the expression of this protein is reduced in nasopharyngeal carcinoma compared with normal nasopharyngeal tissue. In this study, we investigated the tumor-suppressing activity of STGC3 in nude mice injected subcutaneously with Tet/pTRE-STGC3/CNE2 ce

14. The inhibitory effect of photodynamic therapy and of an anti-VCAM-1 monoclonal antibody on the in vivo growth of C6 glioma xenografts
We investigated the effect of photodynamic therapy (PDT) and of an anti-vascular cell adhesion molecule-1 (VCAM-1) monoclonal antibody on the in vivo growth of C6 glioma. Seven days after inoculation with C6 cells, adult male Wistar rats weighing 280-300 g with MRI-confirmed glioma were randomly assigned to 4 groups (N = 15 per group): PDT + VCAM-1 antibody

15. OSTEOSSÍNTESE UMERAL EM POMBOS DOMÉSTICOS (Columba lívia) POR XENOENXERTO ÓSSEO, CONSERVADO EM MEL TRATADOS OU NÃO COM LASER ARSENETO DE GÁLIO (AsGa) / OSTEOSYNTHESIS OF THE HUMERAL IN DOMESTIC PIGEONS (Columba lívia) BY BONE XENOGRAFTS, PRESERVED IN HONEY TREATED OR NOT WITH GALLIUM ARSENIDE LASER (GaAS)
The increase in attendance of wild animals, especially birds, leads to the veterinarian deal with numerous diseases in these animals, being the fractures one of the most frequent injuries in the veterinary clinical surgery. The aim of this study was to reduce the recovery period of birds with humeral fracture in order to anticipate the release of them back i

16. Estudo do efeito da reticulação por genipin em suportes biocompatíveis de quitosana-PVA
The human integument, known as skin, is made up of distinct layers, joined to each other. Its main functions are to protect the underlying tissues, regulate body temperature, and uphold somatic nerve endings. This human organ is subject to several types of effort and injuries caused by physical and chemical agents. By its importance, the skin has been the su

17. Film based on chitosan compared to autologous fat in the prevention of postoperative adhesions dorsal laminectomy in rabbits / Filme à base de quitosana comparado à gordura autógena na prevenção de aderências pós-laminectomia dorsal em coelhos
The adhesions formation after surgical procedures in the spine is a subject well studied in neurosurgery, according to the discomfort and postoperative pain suffered by patients. Several studies have been performed using anti-inflammatories, autologous grafts, xenografts and xenologer biomaterials and even in film form and gel with the aim of reducing or pre

18. Influência da associação da sinvastatina à matriz de osso desmineralizado bovino na reparação de defeitos ósseos em calvária de ratos
Bone defect healing is a constant concern to several areas of Dentistry. A great variety of materials is currently used to help in the healing process as well as to speed it up. Materials such as autografts, xenografts, membranes, some drugs, and the association of some of them are being used. Simvastatin, a substance used to reduce cholesterol levels, has s

19. Physicochemical characterization of two deproteinized bovine xenografts
Calcium phosphate salts, or more specifically hydroxyapatite, are products of great interest in the fields of medical and dental science due to their biocompatibility and osteoconduction property. Deproteinized xenografts are primarily constituted of natural apatites, sintered or not. Variations in the industrial process may affect physicochemical properties

20. Reconstrução acetabular em enxerto ósseo liofilizado humano ou bovino associado a dispositivo de reforço
O presente estudo é uma coorte contemporânea de 49 pacientes (51 quadris) submetidos à reconstrução acetabular com enxerto ósseo liofilizado humano ou bovino, picado e impactado, associado a reforço acetabular. Foi realizado no Serviço de Ortopedia e Traumatologia do Hospital de Clínicas de Porto Alegre (HCPA), no período de maio de 1997 a fevereir

21. Irinotecano ativa a via PI3-quinase/AKT/mTOR em linhagem de adenocarcinoma de colon / Chronic treatment with irinotecan activates the PI3K/AKT/mTOR pathway in HT-29 colon cancer xenografts
Resistance of tumors to chemotherapeutic agents is a common clinical problem in human cancer. Recently, the blocking of PI3-kinase signaling pathway was shown to enhance apoptosis induced by SN-38, an active form of irinotecan. To gain further insight into the molecular events of irinotecan-associated increase in PI3-kinase signaling pathway, aspirin and rap

22. Arsenic trioxide reduces the invasive and metastatic properties of nasopharyngeal carcinoma cells in vitro
Nasopharyngeal carcinoma (NPC) is notorious for the metastases, which are in close association with Epstein-Barr virus-encoded latent membrane protein 1 (LMP1). Arsenic trioxide (As2O3) has been shown to induce apoptosis and differentiation in NPC xenografts. Then, can it repress the cancer cells' metastasis potential? To elucidate this issue, the present st

23. Compared analysis of the matrix remodeling, angiogenesis and new bone formation during the repair of critical size defects treated with autogenous boen or demineralized xenograft / Analise comparativa da remodelação da matriz, angiogenese e neoformaçao ossea durante o reparo de defeito critico tratado com osso autogeno ou xenoenxerto desmineralizado
O objetivo do trabalho foi avaliar comparativamente a neoformação óssea e o perfil de gelatinases 2 e 9 durante o reparo de defeito crítico em crânio de ratos tratados com osso autógeno ou xenoenxerto desmineralizado. Um defeito ósseo de tamanho crítico (8 mm) foi confeccionado no crânio de 90 ratos Wistar (90 dias de vida), e preenchido com osso au

24. Estudo in vitro da compatibilidade do osso bovino misto quimicamente tratado
Biomaterials have been developed and investigated aiming to help bone regeneration. Xenografts of bovine origin stand out due to their biocompatibility, low cost and availability. Some protocols have been tested to develop a chemically treated material containing the anorganic (hydroxiapatite) and the organic (collagen) components of bovine boned: the mixed
