The elevated serum alpha fetoprotein (AFP) concentration in ataxia-telangiectasia (A-T) patients has been known for decades, but the individual variation of AFP levels over time has not been studied. We have followed 12 patients (five girls and seven boys) for 1-12 years (mean 5.5 years) measuring in each patient AFP 2-8 (mean 4) times. Serum AFP levels(More)
The failure of an osseous fracture to heal (development of a non-union) is a common and debilitating clinical problem. Mice lacking the tumor suppressor Pten in osteoblasts have dramatic and progressive increases in bone volume and density throughout life. Since fracture healing is a recapitulation of bone development, we investigated the process of(More)
The purpose of this study was to compare computed tomography density (ρCT ) obtained using typical clinical computed tomography scan parameters to ash density (ρash ), for the prediction of densities of femoral head trabecular bone from hip fracture patients. An experimental study was conducted to investigate the relationships between ρash and ρCT and(More)
Bone fracture non-unions, the failure of a fracture to heal, occur in 10%-20% of fractures and are a costly and debilitating clinical problem. The Wnt/β-catenin pathway is critical in bone development and fracture healing. Polymorphisms of linking low-density lipoprotein receptor-related protein 6 (LRP6), a Wnt-binding receptor, have been associated with(More)
