TL;DR: In this article, the effect of surface roughness of hydroxyapatite (HA) on human bone marrow cell response was investigated using a rotating disc device that applied a linear range of shear stresses to the cells.

TL;DR: Cell attachment and proliferation were surface roughness sensitive and increased as the roughness of Ti alloy increased, and may be explained by the differential adsorption of the two proteins onto smooth and rough Ti alloy surfaces.

TL;DR: The present study defines several conditions under which stress relaxation tests can be performed and investigates the viscoelastic behaviour of trabecular bone in compression through a series ofstress relaxation tests at three strain levels and in three loading directions of each cubic specimen.

TL;DR: The new polymeric composite material introduced by incorporating various low concentrations of multiwalled carbon nanotubes into chitosan (CS), aiming at achieving a novel composite biomaterial with superior mechanical and biological properties compared to neat CS, could be suitable for tissue engineering and particularly for cardiovascular TE applications.

TL;DR: The present results suggest that osteoblasts strong anchorage at the very first moment of their contact with the metallic material leads to their apoptosis, and it is most probable that in several cases this is the reason of failed implantation surgeries involving titanium.
