Sequential and reciprocal epithelial-mesenchymal interactions govern the development of most tissues and organs of the craniofacial region. Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-beta family of secreted signaling molecules that have long been implied to have a significant contribution in this process. However, evidence for such a role during craniofacia...
BACKGROUND In order to gain a better understanding of how growth of the alveolar bone is linked to the vertical development of the face, the purpose of this study was to investigate if there is an association between the cross-sectional morphology of the maxillary and mandibular bodies with the craniofacial height, using images from cone beam computed tomography (CBCT). METHODS From 450 pre-t...
BACKGROUND The RSK2 gene is responsible for Coffin-Lowry syndrome, an X-linked dominant genetic disorder causing mental retardation, skeletal growth delays, with craniofacial and digital abnormalities typically associated with this syndrome. Craniofacial and dental anomalies encountered in this rare disease have been poorly characterized. METHODOLOGY/PRINCIPAL FINDINGS We examined, using X-Ra...
During the first year of life, the brain grows rapidly and the neurocranium increases to about 65% of its adult size. Our understanding of the relationship between the biomechanical forces, especially from the growing brain, the craniofacial soft tissue structures and the individual bone plates of the skull vault is still limited. This basic knowledge could help in the future planning of cranio...
E-mail [email protected] Obstructive sleep apnoea syndrome (OSAS) is a disorder of breathing during sleep characterised by prolonged partial airway obstruction and/ or intermittent complete obstruction (obstructive apnoea) that interrupts normal ventilation during sleep and disrupts normal sleep pattern, affecting about 2–3% of children [1, 2]. Although adenotonsillar hypertrophy remai...
Substantial evidence attests to the capability of the joint to undergo morphological alteration in response to biomechanical forces transmitted to it during function. Measurements expressing the size of mandibular condyles and fossae were obtained from skulls representative of a broad spectrum of subsistence practices and tooth use. Craniofacial dimensions were measured for some groups. Conside...
Ribosome biogenesis is a global process required for growth and proliferation of all cells, yet perturbation of ribosome biogenesis during human development often leads to tissue-specific defects termed ribosomopathies. Transcription of the ribosomal RNAs (rRNAs) by RNA polymerases (Pol) I and III, is considered a rate limiting step of ribosome biogenesis and mutations in the genes coding for R...
The aim of this project was to study the impact on craniofacial morphology from Turner syndrome (TS) karyotype, number of intact X chromosomal p-arms, and age as well as to compare craniofacial morphology in TS with healthy females. Lateral radiographs from 108 females with TS, ranging from 5.4 to 61.6 years, were analysed. The TS females were divided into four karyotype groups: 1. monosomy (45...
OBJECTIVE To compare facial expressiveness (FE) of infants with and without craniofacial macrosomia (cases and controls, respectively) and to compare phenotypic variation among cases in relation to FE. DESIGN Positive and negative affect was elicited in response to standardized emotion inductions, video recorded, and manually coded from video using the Facial Action Coding System for Infants ...
