INTRODUCTION Bone mass measurement is the major tool for the diagnosis of osteoporosis.Dual energy x-ray absorptiometry can be used to measure bone mass in the axial skeleton and whole body with the high accuracy and precision.In this present study,we measured bone mineral density at the lumbar...
At present, clinical research in the pediatric bone field strongly focuses on whole-bone characteristics such as bone mineral density, whereas basic research mainly deals with single molecules and cells. However, bone cells rarely work in isolation but rather form teams that collaborate in a ...
The long-term effect of ovariectomy on the loss of bone mineral density (BMD) was evaluated in rats with and without estrogen treatment; BMD was studied in the lumbar and caudal vertebrae, measured by DXA, to find how the losses of BMD occur in the axial skeleton. Seventy female Wistar ra...
3, Kyle K Nishiyama2, Chiyuan A Zhang2, Thomas L Nickolas2, Elizabeth Shane2 and X Edward Guo1 Hispanic Americans of Caribbean origin are a fast-growing subset of the US population, but there are no studies on bone density, microstructure and biomechanical integrity in this minority group. ...
In conclusion, BMD of children with CRF did not differ from healthy children. Adequate treatment with α-calcidiol or the short duration of renal failure may have attributed to the absence of osteopenia in our patients. BMD of the axial skeleton and growth improved with GHRx. 展开 ...

Bone mass refers to the amount of bone in the skeleton or in one location. However, no technology produces a measurement called bone mass. Bone mineral density is defined as the average concentration of mineral per unit area (for single-energy x-ray absorptiometry [SXA] and dual-energy x-...
Five different bone measurements can be obtained using QCT to study skeletal development in children; the density of cancellous bone, the density of cortical bone, the size of the axial skeleton, the size of the appendicular skeleton and the volume of cortical bone in the appendicular skeleton. ...
but also provide bone mineral density measurements that are independent of body size. Previously, with DXA alone, one could not distinguish between the cortical or outer dense envelope of the bone which predominantly comprises the appendicular skeleton and the trabecular or inner compartment of the bo...
deletion of OB prostaglandin E (EP) 4 receptors does not alter bone density in mice, suggesting that PGE2-induced bone formation is mediated through alternative pathways from cell autonomous EP4 signaling, such as skeletal interoception pathway.83However, how the brain perceives the changes in PGE2...
