1. Behavior study of the doped castor bean polymer rod with bioactive glass and hidroxyapatite in mice femur medullary canal
Abstract Purpose To evaluate the polymer doped rods behavior with bioactive glass and hydroxyapatite for possible application as a fracture fixing method. Methods Twenty eight Rattus norvegicus Wistar underwent bone defect for access to the femoral medullary canal and distributed into three experimental groups: group A - doped castor bean polymer with bi

2. Biocompatibility and osteogenesis of the castor bean polymer doped with silica (SiO2) or barium titanate (BaTiO3) nanoparticles
PURPOSE:To evaluate the biocompatibility and osteogenesis of castor oil polymer doped with SiO2 or BaTiO3 nanoparticles.METHODS: Twenty four male rats Wistar were submitted to bone defect filled with castor oil polymer. The animals were distributed in two experimental groups had been formed with 12 animals each: Group 1 - Castor oil polymer doped with 0.30 g

3. Evaluation of the tensile resistance and the elasticity modulus after a bone repair using the bovine bones grafts and castor bean polymer / Avaliação da resistência à tração e módulo de elasticidade após reparo ósseo de enxertos de osso bovino e polímero de mamona
Devido à limitada capacidade regenerativa, a reparação insuficiente do alvéolo dentário tem representado grande desafio à técnica de implantes osseointegrados, passando a exigir a utilização de enxertos. Este trabalho avaliou um novo biomaterial para enxerto, visando calcular a resistência à tração e o módulo de elasticidade do osso neoformado

4. Bone regeneration after demineralized bone matrix and castor oil (Ricinus communis) polyurethane implantation
Innocuous biocompatible materials have been searched to repair or reconstruct bone defects. Their goal is to restore the function of live or dead tissues. This study compared connective tissue and bone reaction when exposed to demineralized bovine bone matrix and a polyurethane resin derived from castor bean (Ricinus communis). Forty-five rats were assigned

5. Evaluation of ridge preservation after castor bean alloplastic polymer bone graft post-extraction sockets of rats a radiographical and histological study / Avaliação da manutenção da dimensão de rebordo alveolar após enxerto aloplástico de composto ósseo de rícino pós-extração dental em rato, estudo radiográfico e histológico
The aim of this work is to study the behavior of the castor bean alloplastic polymer bone graft on ridge preservation. The dental extraction cicatrization process is an atrophy process. There are preventive techniques for maintenance of the dimensions of the alveolar ridge. These techniques are: dental implant, guided bone regeneration, bone graft and the co

6. Properties of Rhizopus stolonifer Polygalacturonase, an Elicitor of Casbene Synthetase Activity in Castor Bean (Ricinus communis L.) Seedlings 1
Some properties of the polygalacturonase-elicitor from the filtrates of Rhizopus stolonifer cultures have been examined in an attempt to understand its mode of action as an elicitor of casbene synthetase activity in castor bean seedlings. Both the polygalacturonase activity and the elicitor activity are heat-labile with similar heat-sensitivity profiles. Als

7. Chemical, immunochemical, and structural studies of the cross-reactive antigens of Streptococcus mutans AHT and B13.
Two antigenic polysaccharides were extracted from cell walls of the cross-reactive strains Streptococcus mutans AHT (a) and S. mutans B13 (d). The antigens extracted from walls by the hot formamide method, were purified by affinity chromatography on columns containing the galactose-specific lectin from the castor bean and were found to be diheteroglycans con
