Magnesium (Mg) alloys have been demonstrated to be potential orthopedic implants due to their biodegradability in vivo. To enhance its corrosion resistance and improve its osteogenesis, β-tricalcium phosphate (β-TCP) was coated on a Mg alloy (Mg-3AI-1Zn) by phosphating process. In vitro, the human osteosarcoma cell line (SaOS-2) showed significantly good(More)
Of particular concern for the health of astronauts during space travel is radiation from protons and high atomic number (Z), high energy particles (HZE particles). Space radiation is known to induce oxidative stress in astronauts after extended space flight. In the present study, the total antioxidant status was used as a biomarker to evaluate oxidative(More)
To study the in vitro antibacterial activity and biocompatibility of 317L stainless steel containing 4.5% copper alloy (317L-Cu), we produced 317L-Cu stainless steel with epsilon-Cu phase. The cell proliferation of osteoblasts on material surface was detected in vitro. Escherichia coli was cultured with 317L-Cu for evaluating the antibacterial activity. We(More)
Bone and intramedullary bacterial infections are one of the most serious complications of the surgical repair of fractures. To reduce the incidence of implant-related infections, several biomaterial surface treatments with integrated antibiotics, antiseptics, or metal ions have been developed for implants. In this study, we evaluated the antibacterial(More)
