2Sand harm in Taklimakan Desert highway and sand control显示文摘Re puted as a wonderful achievement of the world’s highway construction h istory, the Taklimakan Desert highway is now facing serious sand drift encroachment problems due to its 447-km-long passage of sand sea consist ing of crescent dunes, barchan chains, compound transverse dune ridges and co mplex megadunes. To solve some technical problems in the protection of the highway from sand drift encroachment, desert experts have been conductin g the theoretical and applied studies on sand movement laws; causes, severities and time-space differentiation of sand drift damages; and control ways in cluding mechanical, chemical and biological measures. In this paper the authors give an overall summary on the research contents and recent progress i n the control of sand drift damages in China and hold that the theoretica l research results and practices in the prevention of sand drift encr oachment on the cross-desert highway represent a breakthrough and has an epoch-making significance. Since the construction of protective forest along the cross-desert highway requires large amount of ground water, what will be its environmental consequence and whether it can effectiv ely halt sand drift encroachment on the highway forever are the questions to be studied urgently.HAN Zhiwen,WANG Tao,SUN Qingwei,DONG Zhibao,WANG Xunming(Laboratory of Blo wn Sand Physics and Desert Environment, Cold and Arid Regions Environm ental and Engineering Research Institute, CAS, Lanzhou 730000, China) 2003Journal of Geographical Sciences2003,13,1:13
3百日咳毒素S1亚单位的分子修饰及在重组杆状病毒中的表达显示文摘目的:百日咳毒素既是百日咳杆菌的主要毒性因子,又是重要的保护性抗原,其S1亚单位具有ADP核糖转移酶活性和免疫保护性决定簇。为高效表达前构建的一个丧失酶活性但仍保持保护决定簇的S1变异子,开展了本研究。方法:通过添加人流感病毒血凝素基因信号序列或嵌膜序列的方法,对天然和变异S1亚单位基因片段作了遗传学修饰。然后使用重组杆状病毒技术使这些S1亚单位在昆虫细胞和昆虫幼虫中实现了高水平表达。结果:这些重组S1的表达水平介于每万个昆虫卵细胞018~193μg或每只昆虫幼虫046~498mg之间。天然信号肽和HA信号肽均可完整表达,但后者的切割效率(61%~81%)比前者(16%~19%)更高。所有带信号肽的S1亚单位均呈异质性表达(双带)。结论:重组S1亚单位的表达是高效和正确的,表达的异质性是由于信号肽切割不完全的缘故。于康震 Burnette WN Kaslow HR Mar VL Ahmad S Yilma TD 1999中国免疫学杂志1999,15,2:4
