Using groundwater age determination through CFC analysis and geochemical data from 7 sites in Brittany (France) a hydro-geochemical model for hard rock aquifers is presented. According to the geological structure 3 zones can be defined: the weathered layer, about 30m thick; the weathered-fissured layer (fractured rock with a high density of fissures induced(More)
Growth and patterning of craniofacial sutures is subjected to the effects of mechanical stress. Mechanotransduction processes occurring at the margins of the sutures are not precisely understood. Here, we propose a simple theoretical model based on the orientation of collagen fibres within the suture in response to local stress. We demonstrate that fibre(More)
PURPOSE Autologous bone grafting (BG) remains the standard reconstruction strategy for large craniofacial defects. Calcium phosphate (CaP) biomaterials, such as biphasic calcium phosphate (BCP), do not yield consistent results when used alone and must then be combined with cells through bone tissue engineering (BTE). In this context, total bone marrow (TBM)(More)
Oral and maxillofacial surgeons must be aware of the potentially life-threatening complications of dental extractions in patients with hereditary haemorrhagic telangiectasia because of their high prevalence of pulmonary arteriovenous fistulas. Despite the lack of evidence-based guidelines, antibiotic cover should be given to patients with HHT who require(More)
PURPOSE Ciliary ganglion is a pre-visceral vegetative ganglion, relay of ocular bulb vegetative pathways, concerning three types of fibers: parasympathetic, sympathetic and somatosensory. The objective of this study was to describe the different patterns of distribution of those fibers around the ciliary ganglion to explain rare post-traumatic or(More)
Bone repair is an important concept in tissue engineering, and the ability to repair bone in hypotrophic conditions such as that of irradiated bone, represents a challenge for this field. Previous studies have shown that a combination of bone marrow and (BCP) was effective to repair irradiated bone. However, the origin and role played by each cell type in(More)
