1含新的mucA突变基因黏液型铜绿假单胞菌生物被膜特性的研究显示文摘目的研究含新的mucA突变基因黏液型铜绿假单胞菌(PAE17)在不同条件下形成的生物被膜,以了解新的mucA突变基因对铜绿假单胞菌生物被膜的影响。方法采用PIA平板法鉴定3种铜绿假单胞菌的黏液表型,色氨酸反应法测定其胞外多糖蛋白复合物的合成量;刚果红染色法和静态培养法分别观察其在固态及液态条件下形成的生物被膜;采用电转化法将绿色荧光蛋白表达质粒(pGFPuv)导入上述3种病原菌中,应用改良平板法建立体外生物被膜模型,激光共聚焦显微镜观察不同时间点生物被膜的形成。结果PAE17与PDO300呈现明显的黏液表型,其胞外多糖的产量(101.6μg/ml、118.3μg/ml)显著高于PAEO1(56.3μg/ml),但无论在固态、液态和改良平板法体外生物被膜模型中,PAE17形成的生物被膜均与PDO300迥异,而表现类似PAEO1。结论新的mucA突变基因可能存在藻酸盐以外的其他途径调节生物被膜的形成。陈安群 田德英 宋世会 吴会玲 倪明 Kalai Mathee 2008中华医院感染学杂志2008,18,9:4
2卡介苗预先免疫对大鼠慢性绿脓杆菌性肺炎的影响显示文摘为了探讨卡介苗 (BCG )预先免疫对大鼠慢性绿脓杆菌 (PA )性肺炎模型的影响。采用BCG或灭菌生理盐水皮内注射预先免疫 3周 ,然后由支气管内予以PA攻击 ;2周后评估各组的肺部细菌学、肺组织病理学、肺部细胞因子 (IL 4、IFN γ、TNF α )反应、血清PA特异性抗体IgG水平的变化。结果显示BCG免疫组肺组织内的IFN γ、TNF α水平显著升高 (P <0 0 5 ) ,肺组织匀浆PA菌落计数明显低于生理盐水对照组 (P <0 0 1) ;肺组织病理改变及血清PA特异性抗体IgG水平两组均无显著差异 (P >0 0 5 )。以上结果提示BCG接种能够诱导肺部Th1型免疫反应 ,加快PA性肺炎大鼠肺部的细菌清除 。郭向华 宋志军 吴红 闫萍 覃雪君 Kalai Mathee Niels Hoiby 唐步坚 仇晓强 陈一强 2004现代免疫学2004,24,2:4

4A Comparison Study of Moving Object Index Structures显示文摘The task of selecting the most appropriate method for indexing the data according to application requires a careful comparison study of indices of interests. In particular, we consider object movements by tracing their trajectories within a predefined road network. MV3DR-tree and 3DR-tree constitute our first group indexing the objects moving in free movement scenarios. Besides, Mapping and MON-tree are the second group indexing the locations of objects moving over a network of road. Those access methods mainly organize a group of R-tree in order to index the underlying road network and the object movements. Our goal in this study is to evaluate existing proposals under fair circumstances with respect to storage consumption and spatio-temporal query execution performance. In our comparisons, we discuss the structure's sensibility to query's spatial and/or temporal extent as well as the tradeoff arising between two groups in terms of reliability and disk access performance. We believe that revealing the vulnerabilities of the selected structures, especially Mapping and MON-tree motivates us to design more robust organizations.Utku Kalay Oya Kalipsiz 2009Journal of Computer Science & Technology2009,24,6:2

6Beaconless Position-based Routing with Guaranteed Delivery for Wireless Ad hoc and Sensor Networks显示文摘Existing position-based routing algorithms, where packets are forwarded in the geographic direction of the destination, normally require that the forwarding node should know the positions of all neighbors in its transmission range. This information on direct neighbors is gained by observing beacon messages that each node sends out periodically. Several beaconless greedy routing schemes have been proposed recently. However, none of the existing beaconless schemes guarantee the delivery of packets. Moreover, they incur communication overhead by sending excessive control messages or by broadcasting data packets. In this paper, we describe how existing localized position based routing schemes that guarantee delivery can be made beaconless, while preserving the same routes. In our guaranteed delivery beaconless routing scheme, the next hop is selected through the use of control RTS/CTS messages and biased timeouts. In greedy mode, the neighbor closest to destination responds first. In recovery mode, nodes closer to the source will select shorter timeouts, so that other neighbors, overhearing CTS packets, can eliminate their own CTS packets if they realize that their link to the source is not part of Gabriel graph. Nodes also cancel their packets after receiving data message sent by source to the selected neighbor. We analyze the behavior of our scheme on our simulation environment assuming ideal MAC, following GOAFR+ and GFG routing schemes. Our results demonstrate low communication overhead in addition to guaranteed delivery.CHAWLA Mohit GOEL Nishith KALAICHELVAN Kalai NAYAK Amiya STOJMENOVIC Ivan 2006自动化学报2006,32,6:2
