Jul 18, 2018 · Trabecular BV/TV of Aged animals remained lower than control animals even with exercise during 7 days of reloading and after 28 days of reloading. CONCLUSIONS:These data suggest that aged bone is less responsive to both increased and decreased mechanical loading, and that acute periods of disuse may leave older subjects with a long-term
Regression modeling of the mechanical outcomes revealed competing effects of T2DM on bone mechanical behavior. The trend of higher BV/TV values and the greater mineral content observed in the T2DM specimens increased strength, whereas the greater values of pentosidine in the T2DM group decreased postyield strain and toughness.

Aug 11, 2012 · Fracture of the proximal femur is a major public health problem in elderly persons. It has recently been suggested that combining texture analysis and bone mineral density measurement improves the failure load prediction in human femurs. In this study, we aimed to compare bone texture analysis with three-dimensional (3D) microarchitecture and mechanical properties of trabecular DH36 Chemical Composition , DH36 Mechanical Property DH36 Chemical Composition , DH36 Mechanical Property .

These regions mostly contain minimum values in BV/TV, which were found to predict ultimate stress better than average BV/TV. AB - Human cancellous bone is a heterogeneous material. Despite this, most of the published studies report correlations between mechanical properties and morphometric parameters averaged on the whole specimen. Different subchondral trabecular bone microstructure and May 01, 2020 · The results indicated that BV/TV and pBV/TV might be the key factors for biomechanical properties of subchondral trabecular bone in the three groups (r 2 > 0.5, Table 3). Moreover, the correlation coefficients for BV/TV and pBV/TV were higher in the OA group than in the DDH and NC groups, suggesting that subchondral trabecular bone in the OA
Nov 26, 2009 · The aim of the presented study is to identify some properties of the dynamic behavior of the cancellous bone and to identify the link between this mechanical behavior and the microstructural properties. 7 cylinders of bovine cancellous bone (diameter 41 mm, thickness 14 mm) were tested in quasi static loading (0.001 s-1), 8 in dynamic loading (1000 s-1) and 10 in dynamic loading (1500 s-1 Effects of CNF dispersion on mechanical properties of CNF The variations in the mechanical properties of the CNF/A7xxx nanocomposites according to the concentration of CNFs were analyzed. The yield strength, ultimate tensile strength, and elastic modulus of the nanocomposites for CNF of 0.76wt% increased by 33%, 55%, and 17%, respectively, in comparison to those of the A7xxx matrix.

Marc Bokeloh - Director at Bambooder - (Bambooder The virtue of the extraction process is reflected in the superior mechanical fibre properties:stiffness between 45-55 GPa and a tensile strength between 500-800 MPa. Combined with the low bamboo fibre density (1.35-1.40g/cm³), it is clear that bamboo can rival with traditional glass fibrers.
Bone mechanical properties encompass both geometric and material factors, while the effects of estrogen deficiency on the material and structural characteristics of bone at micro- to nanoscales are still obscure. We performed a series of combined methodological experiments, including nanoindentation assessment of intrinsic material properties, atomic force microscopy (AFM) characterization of Tissue level microstructure and mechanical properties of Trabecular mechanical parameters along the trabecular orientation were significantly correlated with BS/BV, BV/TV, Tb.Th, and DA. In this study, regional variations of microstructural features and mechanical properties in the femoral head of patients with proximal femur fracture were thoroughly investigated at the tissue level.
