BACKGROUND Prenatal tongue development may affect oral-craniofacial structures, but this muscular organ has rarely been investigated. METHODS In order to document the physiology of prenatal tongue growth, we histologically examined the facial and cranial base structures of 56 embryos and 106 fetuses. RESULTS In Streeter's stages 13-14 (fertilization age [FA], 28 to 32 days), the tongue prot...

Skull morphology in achondroplasic (cn/cn) mice was compared with that of normal siblings in order to determine the effects of this chondrodystrophy on skull growth, particular attention being given to dimensions reflecting growth at the synchondroses of the cranial base, the nasal septal cartilage and the condylar cartilage of the mandible. The central section of the cranial base (basicranial ...

I~l a research published by Retzius 1 in 1880, which gives the detailed results of an examination of the various ganglia found in connection with many of the cerebral nerves, the jugu'lar and cer-vical ganglia of the vagus, the jugular and petrosal of the glosso-pharyngeal, the geniculate of the seventh and the Gasserian of the fifth, are described as presenting a structure identical with that ...

We present the implementation of the radiative corrections of the Higgs sector in three public computer codes for the evaluation of the particle spectrum in the Minimal Supersymmetric Standard Model, SoftSusy, SPheno and SuSpect. We incorporate the full one–loop corrections to the Higgs boson masses and the electroweak symmetry breaking conditions, as well as the two–loop corrections controlled...

Abstract Objective To assess the risk of meningioma associated with use high dose cyproterone acetate, a progestogen indicated for clinical hyperandrogenism. Design Observational cohort study. Setting Data from SNDS, French administrative healthcare database, between 2007 and 2015. Participants 253 777 girls women aged 7-70 years living in France who started acetate 2014. had at least one reimb...

Lipomas of the central nervous system are not uncommon, approximately 80 cases having been reported. The most usual site is the dorsal surface of the corpus callosum, although they have frequently been found in the region of the tuber cinereum, the mamniillary bodies, and the midbrain. Lipomas of the spinal cord unassociated with spina bifida are much less common, only 12 cases having been reco...
