Study on the distribution of active centers in novel low Ti-loading MgCl2-supported Ziegler-Natta catalyst     

王剑峰  王立  赵振荣  王文钦  陈涛 《浙江大学学报(A卷英文版)》2004,5(8)

Novel MgCl2-supported Ziegler-Natta (Z-N) catalysts prepared using a new one-pot ball milling method caneffectively control the amounts of Ti-loading in the catalysts. Complex GPC data on polypropylene synthesized by thesenovel catalysts were analyzed using the method of fitting the molecular weight distribution (MWD) curves with a multipleFlory-Schulz function. It was found that multiple active centers exist in these novel catalysts. Detailed study of the effects ofthe Ti-loadings in the catalysts on the distribution of the active centers showed that the Ti-loadings in the novelMgCl2-supported Z-N catalysts might affect the proportion of each type of active centers; and might be the main factorresponsible for the effect of the Ti-loadings on the microstructure, the molecular weight and molecular weight distributionwidth of the resultant polymer, the catalytic activity and polymerization kinetics.  相似文献   

Role of CD97stalk and CD55 as molecular markers for prognosis and therapy of gastric carcinoma patients     

Liu Y  Chen L  Peng SY  Chen ZX  Hoang-Vu C 《Journal of Zhejiang University. Science. B》2005,6(9):913-918

Objectives: To explore the mechanism of development and aggressiveness in gastric carcinomas by investigating the expression and role of CD97 and its cellular ligand CD55 in gastric carcinomas. Methods: Tumor and corresponding normal mucosal tissue, collected from 39 gastric carcinoma patients, were examined by immunohistochemistry and RT-PCR for the expression of CD97 and CD55. Results: CD97stalk was strongly stained on scattered tumor cells or small tumor cell clusters at the invasion front of gastric carcinomas. The expression of CD97stalk was frequently observed in tumors of stage Ⅰ and T1 gastric carcinoma patients. The expression of CD97stalk between Stage Ⅰ and Stage Ⅱ, Ⅲ, Ⅳ specimens showed significant difference (P＜0.05), between T1 and T2, T3, T4 specimens also showed significant difference (P＜0.05). Specimens with tumor invasion depth limited in mucosa of T 1 specimens showed higher positive CD55 expression than specimens with the same tumor invasion depth in T2, T3, T4 specimens, the expression of CD55 between T1 and T2, T3, T4 specimens was significantly different (P＜0.05).There was strong correlation between the distribution patterns of CD97stalk and CD55 on tumor tissues (r=0.73, P＜0.05). Signet ring cell carcinomas frequently contained strong CD97stalk and CD55-staining. Conclusions: Our results suggest that CD97stalk is probably involved in the growth, invasion and aggressiveness of gastric carcinomas by binding its cellular ligand CD55. CD97stalk and CD55 could be useful as molecular markers for prognosis and therapy of gastric carcinoma patients.  相似文献

水稻米香基因的初步定位   总被引：2，自引：0，他引：2  

吴娟 《安徽科技学院学报》2005,19(3):1-5

香味是水稻重要食味品质性状之一,但稻米香味的遗传甚为复杂.早有报道水稻米香基因位于第八条染色体上且与RFLP标记RG28紧密连锁.本实验通过水稻籼粳亚种之间的杂交,利用SSR(Simple Sequence Repeat)分子标记的方法对水稻米香基因进行初步定位.结果表明:稻米香味性状受一对隐性基因控制,且位于第八条染色体SSR标记RM8264和RM1109之间,其遗传距离大约2.1cM.这一结果将对于米香基因的精细定位提供了重要依据.  相似文献
