非相对论极限下的双原子分子的振动光谱

在低温或常温下，双原子分子的振动比较弱，用薛定谔方程求解的双原子分子的振动光谱能满足要求．在高温下双原子分子的振动很强，相对论带来的影响也许要考虑．因此利用狄喇克方程求解一维谐振子系统的能谱，进而讨论相对论对双原子分子振动光谱的修正．     

分子杂交法检测女性尖锐湿疣中的人乳头瘤病毒DNA

本研究以~(32)P标记的重组HPV 11,16,18质粒为探针,采用打点杂交法检测了60例女性尖锐湿疣组织(其中外阴47例,阴道12例、宫颈1例)中的HPVDNA;用限制性内切酶和Southern转印杂交法分析了8例HPV 11 DNA的物理状态。结果检出HPV11 19例,其中外阴13例,阴道5例,宫颈1例,阳性率31.7%;HPV16,18各1例,分别检自阴道和外阴,阳性率均为1.7%;HPV 11均以游离状态存在。这一结果为国内进一步深入研究HPV与生殖器癌之间的关系提供了资料。     

“台海商危期”严厉警告台独势力

9月6日，在澳大利亚举行的APEC会议期间，中国国家主席和美国总统布什如期举行高峰会谈。约一个半小时的会谈超出预定时间半小时，显示出会谈内容广泛和具有实质性。[第一段]     

狂热分子专属：路上最快的四轮“危险品”

Koenigsegg制造的车，数量并不多。比起其它的超级跑车厂商，规模也小了许多。不过，对于每一辆车都用毫不妥协的态度打造，也让这间车厂在车坛上一直享有盛名。Koenigsegg针对少数消费族群所打造的CCX，不但兼具性能与质感，那独特性更是让那少数的狂热份子深深着迷……     

PRELIMINARY STUDY OF A NOVEL HUMAN PAPILLOMAVIRUS TYPE 16L1／E6-E7 CHIMERIC RECOMBINANT DNA VACCINE

Objective Preparations of HPV16 L1/E6 and L1/E7 prophylactic and therapeutic DNA vaccines. Methods The nucleotides within HPV16 E6 and E7 genes, which are responsible for viral transforming activity, were mutated by mage primer site-directed mutagenesis method. The correctly mutated E6 and E7 fragments were separately cloned into an eukaryotic expression vector pVAX1, together with HPV16 L1 gene, generating chimeric recombinants plasmids 1MpVAX1-L1E6, 2MpVAX1-L1E6, 1MpVAX1-L1E7, 2MpVAX1-L1E7 and 3MpVAX1-L1E7. CHO cells were transiently transfected with the individual DNA vaccines by calcium phosphate method. Target protein expressions in the extracts of the transfected cell lines were measured by ELISA and immunohistochemistry, with HPV16 L1 and E6 specific monoclonal antibodies. Results ELISA assays showed the P/N ratios in the cell extracts transfected with L1E6 and L1E7 plasmids were more than 2.1. Immunohistochemistry revealed brownish precipitant signal in cytoplasm and nuclei of the transfected cells. Conclusion Successful constructions of prophylactic and therapeutic DNA vaccine plasmids lay solid foundation for future animal experiment and clinical trial.
