Early Proliferation of Bone Marrow Mononuclear Cells on Collagen Membrane, Bone Graft and Tooth Cementum International Journal of Morphology
Milagres,Débora; Rueff-Barroso,Carlos R; Carvalho,Simone N; Carvalho,Laís de; Monte-Alto-Costa,Andréa; Fischer,Ricardo G; Porto,Luís Cristóvão.
The ultimate goal of periodontal therapy is to repair the damaged periodontal supporting tissues, permitting regeneration of the periodontal ligament. However, the cell response, the supportive matrix and the bioactive molecules use have not yet been well established. Bone marrow mononuclear cells were extracted from rat femurs and tibiae and cultured on a cross-linked collagen membrane, bone graft, or molar tooth to compare cell attachment and early proliferation on these materials. Cell attachment was quantified by light microscopy at 24, 48 and 72h, and cell proliferation was observed under a SEM after 72h. After 24h, the number of cells on bone graft was similar to that of the control and more than twice compared to collagen membrane (q=7.473...

Simple and Low Cost Tridimensional Model of the Cerebral Hemisphere International Journal of Morphology
Rueff-Barroso,Carlos R; Garcia,Karina Seixas; Peruzini,Kamila da Silva; Fernandes-Santos,Caroline; Pereira-Sampaio,Marco Aurelio.
Handmade anatomy models may be a complementary useful tool to dissection and prosection, since the student interacts with the body structure in a three-dimensional way. In this study homemade dough (biscuit) was used to create a brain model. Two anatomy trainees from the medical school of the Universidade Federal Fluminense (Niteroi Brazil) were challenged to model the gross anatomy of the lateral aspect of the brain. They prepared and handled homemade dough to produce a simple and low cost model of the cerebral hemisphere. Styrofoam balls fixed by pins were used to create a framework, and dough rolls were modeled in order to create the brain sulci and gyri. At the end, the model closely resembled three-dimensional features of the human brain. Also, brain...
