Ameloblastic fibrosarcoma (AFS) is a rare malignant tumor of the jaw. The malignant mesenchymal component of AFS has been described as 'fibroblast-like', although little is known about the immunophenotype, except for vimentin expression. Here, we present a case of AFS in a 62-year-old woman. The mesenchymal component displayed the features of either(More)
Developing biomaterial scaffolds to elicit specific cell responses is important in many tissue engineering applications. We hypothesized that the chemical composition of the scaffold may be a key determinant for the effective induction of differentiation in human mesenchymal stem cells (hMSCs). In this study, electrospun nanofibers with different chemical(More)

INTRODUCTION Bioabsorbable screws became widely used for stable fixation in orthognathic surgery as biomechanical technology advanced. Recently, 3D image analyses begin to be used to evaluate surgical changes. The purpose of this study was to evaluate, using 3D vector analysis, the stability of bicortical bioabsorbable screw fixation in mandibular setback(More)
