AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Synthetic bone substitutes are potentially the future gold standard in orthopaedic and traumatologic surgery. The availability of these bone substitutes with different biomechanical properties may well replace autografts in the future as they overcome comp ...
This study reports on in vivo particle induced X-ray emission (PIXE) measurements combined with Rutherford backscattering spectroscopy (RBS) analyses of new remodeled sheep bone formed around TiAIV screws. The implants (screws) were anodized by a modified ...
Mechanical testing of trabecular bone is mainly motivated by the huge impact of osteoporosis in post-menopausal women and the aged in society in terms of social and health care costs. Trabecular bone loss and impairment of its mechanical properties reduce ...
The mechanical properties of healthy and diseased bone tissue were extensively studied in mechanical tests. Most of this research was motivated by the immense costs of health care and social impacts due to osteoporosis in post-menopausal women and the aged ...
The transcription factor Sox4 is vital for fetal development, as Sox4–/– homozygotes die in utero. Sox4 mRNA is expressed in the early embryonic growth plate and is regulated by parathyroid hormone, but its function in bone modeling/remodeling is unknown. ...
Properties of the organic matrix of bone(1) as well as its function in the microstructure(2) could be the key to the remarkable mechanical properties of bone(3). Previously, it was found that on the molecular level, calcium-mediated sacrificial bonds incre ...
Total Hip Replacement (THR) is today a routine procedure executed more than 800'000 times per year worldwide. THR gives generally satisfactory results, although the quality of outcome is inversely proportional to the age of the patient. In parallel, there ...
In the nanocomposite bone, inorganic material is combined with several types of organic molecules, and these complexes have been proposed to increase the bone strength. Here we report on a mechanism of how one of these components, human osteopontin, forms ...
BACKGROUND: A theoretical model and an experimental setup were specifically designed to identify and determine the delay of the cortical bone response (restricted to mineralization and demineralization) to a stress change. METHODS: The in vivo experiment c ...
The mechanical properties of healthy and diseased bone tissue are extensively studied in mechanical tests. Most of this research is motivated by the immense costs of health care and social impacts due to osteoporosis in post-menopausal women and the aged. ...
