    以貉为材料,用两种系统凝胶电泳方法,比较貉LHD同工酶分离效果,实验表明不连续系统凝胶电泳貉LDH同工酶效果要佳。用不连续系统凝胶电泳分析结合LDH同工酶热稳定性和尿素抑制实验,初步鉴定貉LDH同工酶,确定了貉也存在五种标准LDH同工酶。并有其组织特异性图谱。讨论肌肉组织LDH同工酶基因表达与其运动状态之间关系

    用不连续系统聚丙烯酰胺凝胶电泳方法,对东北虎(Panthera tigris altaica)六种组织中LDH同工酶进行电泳分析。分析结果表明:六种组织都具有五种LDH同工酶,但酶带分布类型不同,显示出确定组织特异性。同时测定了东北虎心肌和肝脏LDH同工酶热稳定性和对尿素抑制的敏感性。并对东北虎LDH同工酶电泳行为进行初步探讨

    Determination of the number of ψ(3686) events taken at BESIII

    No full text
    The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
