Suppression of Skpi in mitotic HeLa cells by siRNA resulted in accumulation of telophase cells with elongated inter-cell bridges and with midbodies stretched 2-3 times longer than that of normal cells. These Skpi-eliminated or suppressed cells accumulate higher level of CENP-E, suggesting that spatiotemporal regulation of CENP-E degradation at the midbody is essential for cytokinesis.

接下来，我们用RNA干扰技术系统评估了skp1在有丝分裂末期的具体功能，发现缺少了skp1的HeLa细胞无法完成正常的有丝分裂过程，而更多的以四连细胞的形式存在，从而证明了skp1对于正常细胞周期行进所不可缺少的功能。

The number of differentially expressed genes was 71 at 24h, and 62 at 72h. The metabolisic gene class was the majority among all the differentially expressed genes, and the next was transportational、differentiation and adhesional gene class by turns.1.2. RT-PCR verification of the known HIF-1 targeted genes and proliferation related genesIn the 131 differentially expressed genes, we found 7 known HIF-1 targed genes (ldha、aldoa、eno1、gapdh、tpi1、pgk1、bnip3) and 5 genes (dnaja2、ccnb1、tgfβ2、ccng1、rgs7) which were related to proliferation and cell cycle.

Methods: A model to evaluate lymphocyte proliferation stimulated with a polyclonal activator, concanavalin A, was established by vital dye carboxyl fluorescin diacetate succinmidyl ester labeling technique. Effects of the different doses of anisomycin on the lymphocyte proliferation were estimated by flow cytometry and MTT methods. The propidium iodide labeling technique was applied to assay the effect of the different doses of anisomycin on changes of the lymphocyte cell-cycle stimulated by ConA or by phorbol ester plus Ionomycin. The percentage of the expression level of CD69 and CD25 on the activated lymphocytes was evaluated by fluorescin-conjugated monoclonal antibody double labeling technique.

The numerical simulation shows that the harmonics at the end of the plateau become continuous and form a supercontinuum with a bandwidth of about 80 eV, from which a 50 as isolated pulse in the transform limited case can be generated, when asymmetric molecules are exposed to a multicycle two-color field, which is synthesized by a 10 fs/800 nm fundamental pulse and a 15 fs/1200 nm control pulse.

In this context, we propose a time deployment based, pairwise keymanagement scheme called TDBK. In TDBK, the network lifetime is divided intoseveral consecutive network deployment statuses which are separated by nodedeployment events. Each node to be deployed is assigned its key informationthrough a special two-tier key predistribution mechanism, and timely deletes theuseless part of the key information through the key elimination mechanism eachtime the pairwise key establishment is finished in terms of a new nodedeployment event.

在此背景下，我们提出了一种基于时间部署的对****管理方案(Time Deployment Based Keying，TDBK)，该方案将网络的生命周期分为多个连续的网络部署状态，相邻的部署状态之间通过节点部署事件分隔，每个节点通过特殊的两级****预分配机制来获得用于建立对****的****信息，随后通过****清除机制在每次节点部署事件发生时进行的对****建立过程完成后及时地删除其中无用的****信息。

James Paul Gee, Professor of Literacy at Arizona State University and a leading expert on games, argues that … good games create what's been called a "cycle of expertise" by giving players well-designed problems on the basis of which they can form good strategies, letting them practice these enough to routinize them, then throwing a new problem at them that forces them to undo their now routinized skills and think again before achieving, though more practice, a new and higher routinized set of skills.

通过跟踪观测一年生植物层片在一个生长周期内种类组成及其重要值的变化，并分析变化的生态学机理，得出如下结论：①在固沙区草本层片内，小画眉草的多度、盖度和重要值在群落中所占比例较大，是群落优势种；②在充足的降雨后，一年生植物都突发性萌发，但随着降雨的减少，层片内的一年生植物种群都呈衰退之势，其中小画眉草和虎尾草种群急剧减少，狗尾草、雾冰藜和虫实种群减少幅度不大。

In the cycles before World War II or that of the late 1990s in the United States, the growth periods usually ended with the failure of speculative investments built on a bubble of confidence that bursts or deflates, with the periods of contraction and stagnation reflecting a purging of unsuccessful enterprises as resources were transferred by market forces from less productive uses to more productive uses.
