查询词典 DS

In order to prevent linear PCV2 cyclization, PCR mutagenesis was used to construct the first molecular clone (pSK-2PCV2) by ligating two copies of the complete PCV2 genome with the pBluescript SK vector. In addition, pSK-PCV2 and ds-PCV2 were constructed. PK-15 cells were transfected with above three infectious clones.

本研究应用PCR诱变技术解决了外源片段易于自连的难题，成功将2个PCV2 SD1株全基因组(DQ346683)头尾相接插入到真核生物表达载体pSK的多克隆位点中，构建重组质粒pSK-2PCV2；另外课题组成功构建含单个PCV2全基因组的pSK-PCV2和自身环化质粒ds-PCV2。

The specific properties of materials, such as the palate adhesion, dynamic cruor, anti-bacterial and the degradability of lysozyme, were studied, which provide valuable data for further application. The main creative ideas are listed as follows:(1) The water-retention chitosan/poly vinyl alcohol blend fiber was obtained by coagulating in 10％ NaOH/ethanol solution, and the blend and crosslink due to GA can enhance the mechanical properties of fiber;(2) The controlled degradable chitosan/gelatin blend fiber was obtained by solution filature, and the mechanical properties were improved;(3) The N-acylchitosan with the different degree of substitution were successfully prepared, and the relationship between structure and properties was estabilished;(4) By a new solvent system of 6％ NaOH/4％ urea for cellulose, the blood anti-coagulant function films were prepared by blending cellulose with chitin;(5) In the same solvent system above mentioned, the anti-bacterial blend films based on cellulose and carboxymethyl-chitosan were prepared, and the relationship of DS and the anti-bacterial property was concluded;(6) The controlled degradable chitosan films was obtained by the chemical crosslink.

本论文的主要创新点：（1）以NaOH水溶液／无水乙醇为凝固液，采用溶液纺丝法制备出保水性壳聚糖／聚乙烯醇纤维，共混和戊二醛交联极大提高了壳聚糖纤维力学性能；（2）用壳聚糖和明胶共混，以溶液纺丝法制备出可控降解的壳聚糖／明胶纤维，并大幅度提高了壳聚糖共混纤维的干、湿态抗张强度；（3）确立了不同取代度N-酰基壳聚糖的合成方法及其膜的结构与性能的关系；（4）利用纤维素新溶剂6％NaOH／4％尿素制备出抗凝血性纤维素／甲壳素共混膜；（5）利用上述纤维素新溶剂制备出抗菌性纤维素／羧甲基壳聚糖共混膜，揭示了羧甲基壳聚糖取代度与抗菌性能的关系；（6）制备出可控降解壳聚糖交联膜。
