OBJECTIVE To investigate osteogenesis of bone marrow mesenchymal stem cells (BMSCs) on strontium-substituted nano-hydroxyapatite (Sr-HA) coated roughened titanium surfaces. METHODS Sr-HA coating and HA coating were fabricated on roughened titanium surfaces by electrochemical deposition technique and characterized by field emission scanning electron microscope (FESM). BMSCs were cultured on Sr...

A methodology to engineer roughened inorganic nanostructures on zeolites by deposition and growth of metal hydroxides is reported. Pure-silica (PS) MFI and (aluminosilicate) LTA zeolite crystals are treated by solvothermal methods to deposit inorganic hydroxide (e.g., Mg(OH)2) coatings with nanoscale roughened features on the crystal surfaces in a controlled manner. Detailed characterization of...

Dysplastic acetabula were augmented during total hip replacement by superolateral autografts. In cases of primary arthroplasty these were taken from the excised femoral head and in revision surgery from the iliac crest. Two or (usually) three small grafts were used to facilitate revascularisation; they were fixed with lag screws to the roughened iliac bone above the acetabulum. We reviewed 84 h...

Retrieval studies of total hip replacements with highly cross-linked ultra-high-molecular-weight polyethylene liners have shown much less surface damage than with conventional ultra-high-molecular-weight polyethylene liners. A recent revision hip replacement for recurrent dislocation undertaken after only five months revealed a highly cross-linked polyethylene liner with a large area of visible...

The initial stages of oxidation on roughened Cu(1 1 0) surface were explored by an in situ ultra-high vacuum transmission electron microscope (UHV-TEM). The dynamic observation of the nucleation and growth of Cu oxide islands shows a highly enhanced nucleation rate on the roughened Cu(1 1 0) surface. The kinetic data obtained from the initial stages of the oxidation indicate that oxygen surface...

This paper reports the preliminary finding that the unique surface morphologies of avian red blood cells (aRBCs) infected by the malaria parasite Plasmodium gallinaceum enables the cells to interact with the roughened surface and become immobilized inside the microfluidic channels. It is also found that a roughened glass substrate with ten-pointheight larger than the depth of surface lesions an...

A microfluidic platform is designed, fabricated, tested, and demonstrated that the unique surface morphologies of avian red blood cells (aRBCs) infected by the malaria parasite Plasmodium gallinaceum enables the cells to interact with the roughened surface and become immobilized inside the microfluidic channels. It is also found that a roughened glass substrate with ten-point-height larger than...
