Bone biology is physiologically complex and intimately linked to calcium homeostasis. The literature provides a wealth of qualitative and/or quantitative descriptions of cellular mechanisms, bone dynamics, associated organ dynamics, related disease sequela, and results of therapeutic interventions. We present a physiologically based mathematical model of integrated calcium homeostasis and bone biology...
Bone loss and alterations in bone quality are major causes leading to bone fragility in postmenopausal women. Although bisphosphonates are well known to reduce bone turnover and prevent bone loss in postmenopausal osteoporosis, their effects on other bone properties are not fully characterized. Changes in bone mineral and matrix properties may contribute to the anti-fracture efficacy observed with...
Techniques for assessing bone dynamic are in high demand. Calcium (Ca) kinetic studies are currently being used in our clinical studies of bone turnover in adolescents and elderly. The technique has rarely been compared to the standard method of bone dynamic histomorphometry. We perturbed bone turnover through ovariectomy and sub-optimal dietary Ca in a female rat model to cross-calibrate Ca kinetics...
