The purpose of the bone density measurement is to quantify the density or mass of bone mineral (calcium hydroxyapatite) in a medium consisting not only of the mineral itself, but also fat, muscle and bone marrow constituents as well as other biological materials. Measurements at central sites, ...
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 ...
Bone adapts to the loads that are applied to it (Wolff's Law), and higher mechanical loads lead to increased bone density. This is particularly true during childhood and growth (8). High-impact forces applied to the skeleton appear to confer the greatest benefit. Weight-bearing exercise is ...
The skeleton is one of the most common sites for metastatic cancer, and tumors arising from the breast or prostate possess an increased propensity to spread to this site. The growth of disseminated tumor cells in the skeleton requires tumor cells to inhabit the bone marrow, from which they sti...
g Bone volume fraction (BV/TV) (Exact p value calculated with one-way ANOVA Tukey’s multiple comparisons test: **p = 0.0076, p = 0.0532); and h Bone mass density (BMD) (Exact p value calculated with one-way ANOVA Tukey’s multiple comparisons test: **p = 0.0045, p...
The goals of this study were to determine whether bone density measured using CT (CTBD) can show significant differences in bone loss according to smoking status and pack-years, and to examine the correlation between CTBD and bone mineral density when measured by dual-energy X-ray absorptiometry...
Refers to density 1. Cancellous = spongy = trabecular bone - bone that has spicules of bone interspersed with space - typically prevalent in development 2. Dense = compact = cortical bone - densely arranged osteons or layer of bone - typically found in the diaphysis ...
Bone strength refers to the ability of bones to resist fractures, which is a concept distinct from bone density. While bone mass determines bone mineral density, bone strength is considered a better indicator of fracture risk in conjunction with other traditional risk factors. ...
Physical activity, which inherently stimulates the axial loading of the tibia, femur, and axial skeleton, may also promote bone density after SCI by improving bone vascularization and osteoblast activity [4,112]. Static loading and prone position muscle stimulation appear to be less effective ...
demonstrated improved bone mineral density and motor function in patients with OI, while Högler et al. found increased lean mass, but no changes in bone mass or muscle function [78,81]. A recent study by Berman et al. evaluated the osteogenic potential and tensile strain in vivo on oim...
