This study suggests that HPV16/18 infection and p53 gene mutation are associated with pathogenesis of laryngeal papillomas.

提示HPV16/18感染和p53变异与喉乳头状瘤的发生明确相关，其内在分子机理及临床意义有待进一步阐明。

Based on the above investigation of ideal layer-by-layer growth process, the surface roughening phenomena during the real epitaxial growth are discussed. Some important microscopic dynamic models for molecular-beam epitaxy , which have attracted much attention recently, are studied. Using the master-equation method, the corresponding growth equations are directly derived, and then the scaling behaviors, the universalities, as well as the crossover effects are determined.

在这一理想层状外延生长研究的基础上对实际外延生长过程中十分显著的表面粗化现象进行了探讨，深入研究了几类近年来受到广泛关注的描述分子束外延生长的重要的微观动力学生长模型，采用主方程方法直接得到了相应的非线性生长方程，并确定了标度性质、普适类以及渡越行为。

We synthesize a series of star-burst compounds using triphenylene as the core, alkyl chain as the linker to connect the core with the triphenylamine / carbazole derivatives. The electrochemical properties of those star-burst compounds were studied by cyclic voltammetry. Then we fabricate OLED device by employing those electropolymeric film as the hole-transport layer, and all the devices show well-performance.

因此我们合成出以三伸苯为核心，以碳链当作连接基团，接上数个不同的三苯胺基团或咔唑基团之星状化合物，佐以循环伏安法观察此一系列化合物之电化学行为，探讨不同三苯胺基团或咔唑基团对於此类分子之电聚效果的影响，并将其运用在有机电激发光材料上，皆有不错的效果。

Weibel-Palade bodies are specialized cigar-shaped secretory organelles in endothelial cells, which contain a variety of biologically active molecules. These contents can be released rapidly by stimulation and involved in hemostasis, inflammation and angiogenesis.

Weibel-Palade小体(Weibel-Palade body， WPB)是血管内皮细胞一种特殊的分泌性杆状细胞器，含有多种生物活性分子，受到刺激后可以非常迅速的释放这些内容物，参与止血、炎症和血管生成等生理功能。

Hydrogen bondings induced from carboxylic groups were intentionally designed at the end of the arm of these star-shaped molecules. The hydrogen bonding positions of the so-perpared star-shaped oligofluorenes were similar to those of trimestic acids which has been intensively studied, and this enlightened us to design these moleucles.

通过羧酸基团，我们将(来源：A3bBCe6论7e文网www.abclunwen.com)氢键作用引入到了星状分子的各条臂上，而这种结构和已被广泛研究的苯三酸体系形成了类似的结构：这也是启发我们设计这个分子结构的原因。

The biological characteristic of many vertebrate parvoviruses have been clarified, for example the genome organization, the structure of capsids protein of virus particle, and the relationship between the structure and its function.

它与其它细小病毒一样，病毒粒子无包膜，呈球状二十面体对称，直径22nm，基因组为单链线状DNA分子，含有五种结构蛋白，嶂螂浓核病毒基因组全长为5454个核昔酸，于C含量为38.13%。

Conclusionclustering results revealed that the dendrogram constructed with issr molecular makers was identical with the classic taxonomic system.

结论我国石斛品种的遗传基础比较丰富，issr分子标记构建的亲缘关系树状图与经典分类系统基本一致。

In compared with acceptor emitters, not only can the emission wavelength be tuned (up to 100 nm of red-shift) by H-bonds, but also much higher emission efficiencies of the H-bonded complexes were induced by reduced aggregation and energy transfer from the OXD donor dendrons.

另外，在使高分子形成高分枝结构之研究上、利用不同含量与不同官能基数目之carbazole单体与茀单体进行聚合，可得一系列高分枝状高分子，能使聚茀共轭高分子产生不同之分枝程度结构，这样方式有效改善分子间聚集之现象并且维持高分子主链良好共轭程度，使得产生之高分子具良好的萤光效率。

Screening and identification: the resulting plasmid was extracted by alkali division, identified by restriction enzyme digestions and PCR, observed by 1% agarose gels electrophoresis.

为了提高了目的片段和载体之间的连接效率以及目的片段的拷贝数，本实验所选用的载体是pMD18-T Vector，它是由pUC18用EcoRⅤ切割后在两个3'末端加上单个的碱基'T'而制得的线状分子。

MyosinⅩ, a vertebrate-specific member of myosin super-family, can be detected in most tissues and cells, such as kidney, liver, brain, and so on. Full-length MyosinⅩcan stimulate the formation or stabilization of filopodia. As an actin-based motor protein, MyosinⅩplays a key role connecting cell membrane proteins and cytoskeleton.

肌球蛋白Ⅹ是脊椎动物所特有的细胞骨架蛋白，在脑、肝、肾等大多数组织中都有表达，它的显著特点是定位于细胞丝足的顶端和片状伪足的边缘，MyosinⅩ作为一个动力蛋白分子，起到连接细胞膜蛋白与细胞内骨架蛋白的桥梁作用，因此推测它可能在SVZa成神经细胞的迁移过程中起到重要作用。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
