Furthermore, biological specimens like the bone specimen used in this study are weaker than inorganic materials like minerals and metals, so thicker slices have usually been used.
A material testing system (MTS 458.2 MicroConsole™, Minneapolis, MN, USA) was used to rub the titanium specimens alongside the bone specimen with a fixed displacement rate (0.33 mm/s) over a distance of 30 mm.
For Chiari osteotomy, because the maximal movement distance was 1.0 cm due to its own limitation of antiseptic cadaver specimen, the bone fragment was tried to be moved inward by 1.0 cm.
With every storm, more of them are exposed: everything from the scattered teeth or claws of isolated specimens to the bone beds of entire herds.
In those three specimens, the subchondral bone matrix was also positive.
There was no significant difference in relative expression levels of THBS3, SPARC and SPP1 when the initial biopsy specimens, the primary bone tumor resection specimens, and the biopsies of metastasis were compared.
After biomechanical testing, specimens at the bone-implant interphase were fixed with 10% buffered formalin overnight.
Comparisons with other birdlike dinosaur specimens indicated that the bone structure of this Archaeopteryx was not abnormal.
These 20 specimens were from the bone metastasis group of the patients with bone metastasis only.
