PURPOSE This work evaluated the osteoconductive properties of autogenous demineralized dentin matrix (ADDM) on surgical bone defects in the parietal bone of rabbits, using the guided bone regeneration technique and polytetrafluoroethylene (PTFE) membrane. MATERIALS AND METHODS Surgical bone defects were created in 24 adult rabbits and repaired with either ADDM and PTFE (experimental group) or...

Manipulation of objects and tool-use are known to be controlled by a network of frontal motor and parietal areas. Here, we investigate which of these areas are associated with the somatic sensation of hand-object interactive movement using functional magnetic resonance imaging. To dissociate the sensation of movement from the motor control commands, we used a new kinesthetic illusion. Twelve bl...

UNLABELLED Because of its biocompatibility and osteoconductive properties, calcium-phosphate cement has been used as bone surrogate. OBJECTIVE The purpose of this study was to do a histomorphometric comparison of bone regeneration using hydroxyapatite biphasic ceramic, calcium-phosphate cement and autogenous bone graft. STUDY DESIGN Prospective and laboratorial experiment. MATERIALS AND M...

Today, with emphasis on the mechanical heart and heart transplantation from one human to another andone species to another, a knowledge of the anatomy of the bird’s heart could contribute to theseaccomplishments. Eight male adult ostriches were used to study the heart macroscopically. This studyrevealed that the ostrich heart has some different features from the other birds. In the ostrich, fib...
