Effects of oral implants with miR-122-modified cell sheets on rat bone marrow mesenchymal stem cells
The aim of the present study was to regulate the transformation of bone marrow mesenchymal stem cells (BMMSCs) to osteoblasts to promote bone formation and osseointegration surrounding oral implants. BMMSCs were cultured using the whole bone marrow adherence method. Cell surface markers were detected by flow cytometry, and multi‑lineage differentiation potential was detected by osteogenic and a...
Hybrid nanostructured arrays based on carbon nanotubes (CNT) and palladium or titanium dioxide materials have been synthesized using self-supported and silicon-supported anodized aluminum oxide (AAO) as nanoporous template. It is well demonstrated that carbon nanotubes can be grown using these membranes and hydrocarbon precursors that decompose at temperatures closer to 600°C without the use of...
In the present study, the finite element analysis of the hot deep drawing process of commercially pure (CP) titanium has been performed without the blank holder in order to investigate the influence of temperature (T), die radius (Rd) and blank diameter (D) on the maximum punch force (Fp) and minimum thickness of the blank (t). Tensile tests were first conducted to extract...
