| 1 | Effects of TIG Surface Melting and Chromium Surface Alloying on Microstructure, Hardness and Wear Resistance of ADI显示文摘Microhardness and wear resistance of different microstructures formed by TIG(tungsten inert gas) surface melting and chromium surface alloying(using ferrochromium)of ADI(austempered ductile iron)were studied. Sur- face melting resulted in the formation of a ledeburitic structure in the melted zone, and this structure has a hardness up to 896 HV as compared to 360 HV in that of ADI. Moreover, chromium surface alloying resulted in the forma- tion of different structures including:(1)a hypereutectic structure consisting of primary(Fe,Cr)_7 C_3 carbides and a eutectic matrix of transformed austenite(into martensite and retained austenite),as also (Fe,Cr)_7C_3 carbides, with a hardness of 1 078 HV;(2) a hypoeutectic structure consisting of the same eutectic along with transformed primary austenite, with a hardness of 755 HV; and (3) a ledeburitic structure with an acicular morphology and a hardness of 896 HV. The results also indicated that surface melting reduced the wear rate of the ADI by approximately 37%. Also, chromium surface alloying yielded a superior wear behavior and reduced the wear rate of the treated specimens by about 38% and 70%, depending on the structures formed. | A Amirsadeghi M Heydarzadeh Sohi S F Kashani Bozorg | 2008 | Journal of Iron and Steel Research(International)2008，15，4： | 3 |
| 2 | Contrast-induced acute kidney injury in kidney transplant recipients: A systematic review and meta-analysis显示文摘AIM To evaluate the incidence of contrast-induced acute kidney injury(CIAKI) in kidney transplant recipients. METHODS A literature search was performed using MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from the inception of the databases through July 2016. Studies assessing the incidence of CIAKI in kidney transplant recipients were included. We applied a randomeffects model to estimate the incidence of CIAKI.RESULTS Six studies of 431 kidney transplant recipients were included in the analyses to assess the incidence of CIAKI in kidney transplant recipients. The estimated incidence of CIAKI and CIAKI-requiring dialysis were 9.6%(95%CI: 4.5%-16.3%) and 0.4%(95%CI: 0.0%-1.2%), respectively. A sensitivity analysis limited only to the studies that used low-osmolar or iso-osmolar contrast showed the estimated incidence of CIAKI was 8.0%(95%CI: 3.5%-14.2%). The estimated incidences of CIAKI in recipients who received contrast media with cardiac catheterization, other types of angiogram, and CT scan were 16.1%(95%CI: 6.6%-28.4%), 10.1%(95%CI: 4.2%-18.0%), and 6.1%(95%CI: 1.8%-12.4%), respectively. No graft losses were reported within 30 d post-contrast media administration. However, data on the effects of CIAKI on long-term graft function were limited.CONCLUSION The estimated incidence of CIAKI in kidney transplant recipients is 9.6%. The risk stratification should be considered based on allograft function, indication, and type of procedure. | Wisit Cheungpasitporn Charat Thongprayoon Michael A Mao Shennen A Mao Matthew R D'Costa Wonngarm Kittanamongkolchai Kianoush B Kashani | 2017 | World Journal of Transplantation2017，7，1： | 2 |
