Recombinant CD 59 protein using ICAM-2 promoter with enhancer can be exlSt:essed highly, effectively and specifically in PAECs and transgenic mice.

以人细胞间黏附因子Ⅱ(ICAM-2)为启动子并带增强子的CD59重组基因在猪的血管内皮细胞及小鼠体内均高效特异表达。

While AcMNPV and BmNPV had no stimulatory effect in nonsensitive cell lines BmNPV hr3 has been demonstrated to increase the transcriptional activity of cislinked hel510 promoter. In this study, Sf-21, Bm-N and Hi-5 cell lines were transfected with pBmhel510luc-hr3down, and then were infected with each of AcMNPV, BmNPV and HyNPV. The results indicated that viral factors could interact with hr3 to significantly copromote the transcriptional level of hel510 promoter.

BmNPV hr3已被证明具有增强子功能，将hr3与hel510启动子顺式连接的质粒pBmhel510luc-hr3down转染Sf-21、Bm-N和Hi-5细胞后，再用上述三种病毒分别感染每一种细胞，hel510启动子的转录活性得到显著提高，表明病毒因子能够识别hr3，二者通过相互作用，共同增强解旋酶基因启动子的转录水平。

Studies of heavy quarkonium production in high energy collisions may provide im-portant information on both perturbative and nonperturbative QCD.

本文在微扰QCD的框架下讨论重夸克偶素的产生和高能强子对撞机上的硬衍射物理。

As is well known, in high energy collisions the hadromzation of partons, being a soft process, can not be analyzed using perturbative QCD.

在高能碰撞多粒子产生中，部分子的强子化是一个软过程，不能用微扰QCD来进行研究。

The theory of Quantum Chromo-Dynamics, which describes the strong interactions, has two different vacuum states—perturbative vacuum and physical vacuum.

强相互作用的基本理论量子色动力学有微扰真空和物理真空两种不同的真空态，带色的夸克和胶子不能在通常的物理真空中运动，而只能被禁闭在色中性的强子中。

There are many methods in dealing with this problem, such as naive factorization, QCD factorization approach, perturbative QCDfactorization approach, etc.

长期以来，为了提高强子矩阵元计算的精度，人们提出了多种因子化方法，例如：简单因子化方法、QCD因子化方法、pQCD因子化方法，等等。

We have first studied a new concept, PPSD (PHOS Pre-Shower Detector), for the charged particle detector.

之二，对PHOS中的簇射进行拓扑分析，从而区分电磁簇射和强子簇射。

Erve growth factor combined with its receptor, activated Ras - MAP kinase , mitogen - activated protein kinase kinase is the important regulating factor that make IkB kinase, IKK, phosphated, IkB kinase make the IκBα:(the subunit of NF -κB ) phosphated, the phosphated IkBα degraded, and p65 - p50 heterodimer can be formed, then the heterodimer translocated to nucleus and combined with the promoter domain or other consensus sequence.

GF与其受体相结合，最后可以激活Ras-有丝分裂激活的蛋白激酶途径，有丝分裂激活的蛋白酶激酶(MEKK1)是IγB激酶发生磷酸化的重要调节因子，IKK使NF-κB的亚单位IKBα发生磷酸化，磷酸化的IKBα发生降解，而最后留下p65-p50二聚体，该二聚体然后转位到细胞核内与κB基因的增强子区域或与他的顺式作用序列结合。

The effect in the shoot is caused by the increased influx, mediated by HKT1;1, of Na+ into stelar root cells, which is demonstrated in planta and leads to a reduction of root-to-shoot transfer of Na+.

本研究介绍了拟南芥成熟根部Na+运输体HKT1；1的表达降低了37%到60%Na+在芽部的累积量，HKT1；1在成熟根部专一性的表达是通过增强子诱导表达系统过量表达来实现的。

Here we show that consolidation but not reconsolidation of inhibitory avoidance memory requires the expression of the transcription factor CCAAT enhancer binding protein beta in the hippocampus.

这里，我们发现固化但不是禁止回避记忆的再固化需要转录因子CCAAT增强子的表达，结合到海马回的蛋白质β上。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
