1. Le Thi Bang, Giichiro Kawachi, Masaharu Nakagawa, Melvin Munar, Kunio Ishikawa, Radzali Othman, The use of poly (ε-caprolactone) to enhance the mechanical strength of porous Si-substituted carbonate apatite, Journal of Applied Polymer Scince, 10.1002/app.39164, 130, 426-433, 2013.03, Poly(e-caprolactone) (PCL)/silicon-substituted carbonate apatite (Si-CO3Ap) composite derived from the interconnected
porous Si-CO3Ap reinforced with molten PCL was prepared. PCL was used to improve the mechanical properties of a porous apatite
by a simple polymer infiltration method, in which the molten PCL was deposited through the interconnected channel of porous
Si-CO3Ap. The PCL covered and penetrated into the pores of the Si-CO3Ap to form an excellent physical interaction with Si-CO3Ap
leading to a significant increase in diametral tensile strength from 0.23 MPa to a maximum of 2.04 MPa. The Si-CO3Ap/PCL composite
has a porosity of about 50–60% and an interconnected porous structure, with pore sizes of 50–150 lm which are necessary for
bone tissue formation. These results could pave the way for producing a porous, structured biocomposite which could be used for
bone replacement..
2. Xingling Shi, Masaharu Nakagawa, Lingli Xu, Alireza Valanezhad, Preparation of Magnesium Containing Bioactive TiO2 Ceramic Layer on Titanium by Hydrothermal Treatment, Advances in Bioceramics and Porous Ceramics, 10.1002/9781118217504, 5, 85-89, 2013.03, [URL], Surface modification on titanium was carried out in order to improve its bioactivity. Pure titanium was hydrothermally treated in distilled water and 0.1 M MgCl2 solutions at 200C for 24 h. Surface morphology, roughness, wettability and chemical composition were characterized before and after treatment. Bovine serum albumin was used as model to study protein adsorption. MC3T3-E1 cells were cultured and initial cell attachment, morphology, proliferation were evaluated. After hydrothermal treatment, nano-sized precipitations were observed and samples showed superhydrophilicity. Magnesium (Mg) was immobilized into titanium surface by hydrothermal treatment.
Protein adsorption was significantly increased on Mgcontaining samples. Cell attachment was improved and cell spreading was enhanced on Mg-containing samples compared with untreated or those treated in distilled water.
Increased early cellular attachment on the MgTi surface resulted in subsequent increase of number of proliferated cells. Hydrothermal treatment in MgCl2 solution was expected to be an effective method to fabricate titanium implant with good bioactivity..
