Effect of low-level laser therapy on the membrane induced by the Masquelet tech...
Coris,Jeniffer Gabriela Figueroa; Rahal,Sheila Canevese; Fonseca-Alves,Carlos Eduardo; Mamprim,Maria Jaqueline; Inamassu,Letícia RochaABSTRACT Purpose: To evaluate the low-level laser therapy (LLLT) on the membrane induced by the Masquelet technique in rabbits. Methods: Twelve Norfolk rabbits at approximately 3 months of age were used. A 1-cm segmental defect was induced in both radii, which were filled with polymethylmethacrylate cylinder. LLLT was used postoperatively in the bone defect of one of the forelimbs every 48 hours for 15 days. Si...
Use of hyaluronic acid associated with triamcinolone acetonide or ozone gas in ...
Brombini,Giovanna Cristina; Rahal,Sheila Canevese; Fabro,Alexandre Todorovic; Santos,Ivan Felismino Charas dos; Tsunemi,Miriam HarumiABSTRACT Purpose: To evaluate the effects of the intra-articular application of hyaluronic acid associated with triamcinolone acetonide, and ozone gas in the treatment of induced osteoarthritis in rabbit’s stifles. Methods: Twenty-one Norfolk rabbits were submitted to cranial cruciate ligament transection of the left stifle. After six weeks of the surgery, the rabbits were randomized assigned into three groups:...
Ex vivo study of use of physiotherapy ultrasound in polymethylmethacrylate bead...
Maciel,Luigi Milanez Ávila Dias; Rahal,Sheila Canevese; Melchert,Alessandra; Genari Filho,Tulio; Maciel,Carlos Dias; Santos,Ivan Felismino Charas dosAbstract Polymethylmethacrylate bone cement is a standard material used as antibiotic carrier in the orthopedic surgery. The ultrasonic energy method is capable of triggering biological effects based on both thermal and non-thermal mechanisms. The aim of the current study is to analyze methylene blue dispersion in polymethylmethacrylate beads, in association with the acoustic field generated by non-thermal ultr...
Biomechanical Analysis of Locking Reconstruction Plate Using Mono- or Bicortica...
Santos,Rogerio Rodrigues; Rahal,Sheila Canevese; Mesquita Neto,Camilo; Ribeiro,Celso Roberto; Sousa,Edson Antonio Capello; Foschini,Cesar RenatoThis experimental in vitro study evaluated the influence of screw length on the mechanical properties of a locking reconstruction plate designed with locking rings inserted into plate holes. Synthetic bone cylinders with 10 mm fracture gap and seven-hole locking reconstruction plates were used. Two groups of bone-plate constructs were assembled: Group 1 – three monocortical screws on each fracture side, Group 2...
In vitro evaluation of three different biomaterials as scaffolds for canine mes...
Pereira-Junior,Oduvaldo Câmara Marques; Rahal,Sheila Canevese; Lima-Neto,João Ferreira; Landim-Alvarenga,Fernanda da CruzPURPOSE: To evaluate in vitro ability the of three different biomaterials - purified hydroxyapatite, demineralized bone matrix and castor oil-based polyurethane - as biocompatible 3D scaffolds for canine bone marrow mesenchymal stem cell (MSC) intending bone tissue engineering. METHODS: MSCs were isolated from canine bone marrow, characterized and cultivated for seven days with the biomaterials. Cell proliferat...
Low-level laser on femoral growth plate in rats
Oliveira,Sidney Piesco de; Rahal,Sheila Canevese; Pereira,Elenize Jamas; Bersano,Paulo Ricardo de Oliveira; Vieira,Fabio de AlmeidaPURPOSE: To determine the influence of low-level laser therapy on femoral growth plate in rats. METHODS: Thirty male Wistar rats aged 40 days were divided into two groups, G1 and G2. In G1 the area of the distal growth plate of the right femur was irradiated at one point using GaAlAs laser 830 nm wavelength, output power of 40 mW, at an energy density of 10 J/cm². The irradiation was performed daily for a maxim...
Afecções ortopédicas dos membros pélvicos em cães: estudo retrospectivo
Souza,Mariana Moraes Dionysio de; Rahal,Sheila Canevese; Padovani,Carlos Roberto; Mamprim,Maria Jaqueline; Cavini,José HenriqueO objetivo deste estudo foi caracterizar as afecções ortopédicas dos membros pélvicos em cães atendidos no Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia, UNESP Botucatu (São Paulo - Brasil), durante um período de 7 anos. De um total de 889 animais avaliados, 31,9% apresentaram fraturas dos ossos longos, 15,1% displasia coxofemoral, 13% luxação de patela, 11,7% ruptura do ligamento cruzad...
Evaluation of castor oil-based polyurethane membranes in rat bone-marrow cell c...
Cerejo,Sofia de Amorim; Rahal,Sheila Canevese; Lima Neto,João Ferreira de; Voorwald,Fabiana Azevedo; Alvarenga,Fernanda da Cruz Landim ePURPOSE: To evaluate three methods to isolate rats MSCs and to analyze the potential of a castor oil polyurethane base membrane as a scaffold for MSCs. METHODS: Four male Wistar rats, aged 20-30 days were used. Bone marrow aspirates from femur and tibia were harvested using DMEM high glucose and heparin. The cell culture was performed in three different ways: direct culture and two types of density gradients. A...
Estudo retrospectivo de cães com luxação patelar medial tratados cirurgicamente
Souza,Mariana Moraes Dionisyio de; Rahal,Sheila Canevese; Padovani,Carlos Roberto; Mortari,Ana Carolina; Mendes,Péricles NobregaO trabalho teve por objetivo avaliar, por meio de estudo retrospectivo, a evolução de 48 cães de porte médio a toy com luxação patelar medial de desenvolvimento submetidos a procedimentos cirúrgicos corretivos. Dos membros com grau 1 (n=15), 46,7% foram tratados apenas com a superposição do retináculo lateral, e 53,3%, com a superposição do retináculo lateral e o aprofundamento do sulco troclear, não sendo dete...
Resposta tecidual a implantes de discos de poliuretana de mamona nas formas pré...
Celeste,Samanta Aires; Rahal,Sheila Canevese; Pereira-Júnior,Oduvaldo Câmara Marques; Sequeira,Julio Lopes; Melo,Simone MacedoO trabalho teve por objetivo avaliar a resposta tecidual à implantação de discos de poliuretana derivada do óleo de mamona confeccionados de duas formas distintas, na forma pré-moldada fornecida pela indústria e em biomassa moldada no momento da aplicação, de forma a observar se haveria algum tipo de reação local tardia associada à possível continuidade do processo de endurecimento final do biomaterial. Foram u...
