Cranial sutures and diploae morphology.
The aim of the study was to assess the normal cranial suture and bone diploae ultrastructural morphology. Two types of sutures from different specimens were collected. The micro-CT scanning provided a three-dimensional view of the sutures at a microscopic level thus allowing the evaluation of the development stage and a rapid analysis evaluation of bone and diploae morphology. In the meantime, ...
متن کاملAcute upregulation of hedgehog signaling in mice causes differential effects on cranial morphology
Hedgehog (HH) signaling, and particularly signaling by sonic hedgehog (SHH), is implicated in several essential activities during morphogenesis, and its misexpression causes a number of developmental disorders in humans. In particular, a reduced mitogenic response of cerebellar granule cell precursors to SHH signaling in a mouse model for Down syndrome (DS), Ts65Dn, is substantially responsible...
متن کاملThree-dimensional cranial suture morphology analysis.
The aim of the study was to assess the normal and synostosed coronal cranial sutures morphology at an ultrastructural level. Different operative specimens of human coronal sutures were collected. Three-dimensional reconstruction of the microcomputed tomography (micro-CT) slices were obtained and compared with the representative histologic sections. The micro-CT scanning provides a three-dimensi...
متن کاملObjective Three-Dimensional Analysis of Cranial Morphology
OBJECTIVE The lack of adequate means to objectively characterize cranial shape contributes to ongoing controversies in the surgical management of craniosynostosis. Cranial shape analysis must address relevant clinical questions objectively and thoroughly and must be broadly applicable across the spectrum of normal and abnormal. Herein, we demonstrate and statistically validate an automated comp...
متن کاملCranial morphology in the brachygnathic sheep
BACKGROUND Craniofacial morphology of sheep with phenotypically observed mandibular distocclusion was analysed using the multivariate techniques principle component analysis and cluster analysis in order to test whether different types of craniofacial malformations can be distinguished. RESULTS The results showed 8 principal components with a variance of 82.72% in the database. The method cre...
