To investigate the effects of Mg-6Zn alloy on the healing of the common bile duct (CBD), Mg-6Zn alloy stents were implanted into the CBDs of rabbits. Stainless steel stents were transplanted into a second group of rabbits to serve as a control. Computed tomography (CT) scanning was performed and weight loss was recorded to evaluate the in vivo degradation process. Hematoxylin and eosin staining...

Purpose: The paper presents results of the research connected with the development of new approach based on the neural network to predict chemical composition and cooling rate for the mechanical properties of the Mg-Al-Zn cast alloys. The independent variables on the model are chemical composition of Mg-Al-Zn cast alloys and cooling rate. The dependent parameters are hardness, ultimate compress...

BACKGROUND This study was designed to investigate the effect of BMSCs transfected BMP-2 composite with magnesium alloy rod in the repair of the femoral head necrosis in New Zealand white rabbits. Multifactorial but mostly traumatic, osteonecrosis of the femoral head account for 10 % of the 250,000 total hip arthroplasties done annually in the United States while its prevalence in most countries...

Mg(OH)2 conversion coatings were formed on an Mg-2Zn-0.5Mn-Ca-Ce alloy via hydrothermal method at three different synthesizing temperatures (160, 170 and 180 ̋C). The effect of synthesizing temperature on microstructure and electrochemical property of the coatings were systematically studied. With increasing synthesizing temperature, the coating became thicker due to the faster reaction and dep...

The microstructures of ¡-Mg, long-period stacking ordered (LPSO) phases, and kink bands in a Mg­Y­Zn alloy were observed by transmission electron microscopy (TEM). The results showed that extruded Mg97Zn1Y2 alloy included different kinds of phases: 2H-Mg, 2H-Mg with many stacking faults, 14H and 18R. Kink bands tended to occur in areas where there were many intermetallic compounds. The element ...
