Introduction: Polyurethanes (PU) have long been used for biomedical applications due to their excellent mechanical properties and reasonable biocompatibility. However, polyether urethane elastomers are susceptible to biodegradation. Silicones are known to be biostable and biocompatible, making them an ideal replacement for the polyether soft segment of polyurethanes. As a result, a new silicone...

Magnetic properties and heat generation characteristics of a bio-compatible ceramic Mg1þxFe222xTixO4 system have been investigated as an implant material for the magnetic induction hyperthermia. Curie temperature ðTcÞ of the ceramic decreases with increasing x; and become Tc , 350 K at x 1⁄4 0:35 and ,315 K at x 1⁄4 0:38; which is suitable Curie temperature for implant material. The temperature...

Rhombohedral Boron Nitride (r-BN) layers were grown on sapphire substrate in a hot-wall chemical vapor deposition reactor. Characterization of these layers is reported in details. Xray diffraction (XRD) is used as a routine characterization tool to investigate the crystalline quality of the films and the identification of the phases is revealed using detailed pole figure measurements. Transmiss...

All operations were performed under general anaesthesia using a limbal approach to the insertions of the muscles, similar to that recently described by Fells (I97 i). The 6/o Ethiflex suture was then used in the standard manner employing a "whip" stitch on the edge of each muscle. At the moment the suture is presented with a io-mm. taper-point needle. This is not ideal, but no problems, apart f...

Background. Electro Acupuncture (EA) uses the acupuncture needle as an electrode to apply low-frequency stimulation. For its safe operation, it is essential to prevent any corrosion of the acupuncture needle. Objective. The aim of this study is to find an available material and determine the possibility of producing a standard EA needle that is biocompatible. Methods. Biocompatibility was teste...
