We developed a fiber optical probe to measure spatially resolved diffuse reflectance from beef samples in VIS-NIR bandwidth of 450-950nm. The optical scattering and absorption coefficients were obtained by fitting the measurements with diffuse equation. Beef absorption coefficients are related to the sample chemical compositions such as the concentration of(More)
The Fear Avoidance Beliefs Questionnaire (FABQ) was translated and cross-culturally adapted for China. Its psychometric properties were then evaluated in Chinese-speaking patients with low-back pain and the scales were tested for internal consistency, reproducibility, ceiling-and-floor effects, construct validity and responsiveness. A total of 15 patients(More)
Autogenous bone grafts are widely used in the repair of bone defects. Growth factors such as bone morphogenetic protein 2 (BMP-2) can induce bone regeneration and enhance bone growth. The combination of an autogenous bone graft and BMP-2 may provide a better osteogenic effect than either treatment alone, but BMP-2 is easily inactivated in body fluid. The(More)
