Knowledge of the organization of the components of bone is of primary importance in understanding how this tissue responds to stresses and provides a starting point for the design and development of… Expand
Dexamethasone in osteogenic medium strongly induces adipocyte differentiation of mouse bone marrow stromal cells and increases osteoblast differentiation
BackgroundOsteoblasts and adipocytes share a common mesenchymal stem cell origin. Therefore, it has been suggested that the accumulation of marrow adipocytes observed in bone loss is caused by a… Expand

Biological tissues have a complex and heterogeneous 3D structure, which is only partially revealed by standard histomorphometry in 2D. We here present a novel chemical compound for contrast-enhanced… Expand
Heterogeneous microchemistry between CdSO4 and CaCO3 particles under humidity and liquid water.
Laboratory experiments using in situ Raman imaging combined with ex situ TOF-S-SIMS demonstrate the behavior of CdSO4·8/3H2O microparticles in contact with 101¯4 CaCO3 (calcite) surface under three… Expand
Region specific Raman spectroscopy analysis of the femoral head reveals that trabecular bone is unlikely to contribute to non-traumatic osteonecrosis
Non-traumatic osteonecrosis (ON) of the femoral head is a common disease affecting a young population as the peak age of diagnosis is in the 40 s. The natural history of non-traumatic ON leads to a… Expand
Tissue-specific mineralization defects in the periodontium of the Hyp mouse model of X-linked hypophosphatemia.
X-linked hypophosphatemia (XLH) is a dento-osseous disorder caused by inactivating mutations in the PHEX gene, leading to renal phosphate wasting and hypophosphatemia, and impaired mineralization of… Expand
Physico-chimie de micro particules pour la prévision de la spéciation du plomb, du zinc et du cadmium dans des aérosols de pollution atmosphérique

- 19 December 2006
De nos jours, les industries metallurgiques sont a l'origine de la majeure partie des emissions dans l'air de poussieres contenant des metaux. Ces activites emettent de fines particules de PbSO4, de… Expand
Molecular interactions between zoledronic acid and bone: An in vitro Raman microspectroscopic study.
The aim of this study was to investigate molecular interactions between a bisphosphonate (BP), zoledronic acid, and bone tissue by the use of Raman microspectroscopy. In this way, samples of… Expand
