1睾丸主要血管或睾丸网旁取精点与取精成功率不具显著相关性:以220例非梗阻性无精子症患者行传统或显微睾丸取精术为例显示文摘采用传统与显微睾丸取精术相结合方式对220例梗阻性无精症患者行精子提取术,如果传统手术方式未见精子即为阴性取精位点,然后选取2—3个阴性取精位点行显微睾丸取精术。术中通过手术显微镜评价睾丸血管系统,同时记录阳性取精位点与睾丸血供的关系。总的精子获取率为58-2%,早期应用传统手术方式精子获取率为46.8%,而后行显微睾丸取精术则精子获取率增加11.7%。故显微睾丸取精术的应用可显著增加精子获取率(P=0.017),且在睾丸网或睾丸主要血管处并不能显著增加阳性取精位点。J Ullrich Schwarzer Heiko Steinfatt Heiko Steinfatt Manfred Schleyer Frank M Kōhn Klaus Fiedler2, Irene von Hertwig Gottfried Krüsmann Wolfgang Würfel 2013Asian Journal of Andrology2013,15,6:5
2Carbonates as Foaming Agent in Chip-based Aluminium Foam Precursor显示文摘Replacement of TiH2 as foaming agent by CaCO3(lime) and CaMg(CO3)2(dolomite) for AlMg4.5-and AlSi9Cu3-foams was investigated considering inluences on foaming capability and cellular structure.Precursor materials were produced from alloy chip and powder mixtures by means of the thixocasting process.AlSi9Cu3 variants showed expansion levels suffcient for commercial use.Variations in expansion observed when CaCO3 and CaMg(CO3)2 were compared as foaming agent are explained based on the course of decomposition.Improved performance of dolomite-based foams relies on formation of stabilizing MgO phases,which do not develop during decomposition of CaCO3 in Al-Si-CuMarco Haesche Dirk Lehmhus Jrg Weise Manfred Wichmann Irene Cristina Magnabosco Mocellin 2010Journal of Materials Science & Technology2010,26,9:3
