The coordination geometry of the Eu atom is best described as a strongly distorted square-antipyrism.. The two Eu atoms are bridged by two N-oxide oxygen atoms forming a dimeric unit with crystallographic inversions centre. The Eu……Eu distance is 4.2137(9)〓. The two europium atoms and two bridging oxygen atoms is coplanar. The angles of Eu(1)-O(7)-Eu(1A) and O(7)-Eu(1)-O(7A) are 117.82(14)° and 62.18(14)°, respectively. 15 is the first dinuclear triboluminescent lanthanide complex reported.

Heat shock factor binding protein 1(HSBP1) is a nuclear-localized, novel, conserved, low molecular weight (00 residues) transcriptional factor, which may repress the activity of the heat shock factor 1 (HSF1) by binding HSF1 active trimerization domain.

热激因子结合蛋白1（heat shock factor binding protein 1， HSBP1）是一种新发现的高保守、低分子质量、定位于核中的一种转录因子，它可抑制HSF1的转录域活性，并协同HSP70负调控热激反应。

With two tripodal ligands, dtma and tmpa, dtma=diethylenetriamine-N'-acetate and tmpa=tris(2-pyridyl-methylamine and a polyamine ligand, trien (=triethylenetetramine), serving as terminal ligands, we synthesized 19 species of new imidazolate -bridged Cu-Zn, Zn-Zn and Cu-Cu, and other relating compounds, in which 〓 and 〓 complexes are model compounds of Cu, Zn-SOD.

用不等臂三脚架dtma(diethylenetriamine-N'-acetate)、直链trien和等臂三脚架tmpatris(2-pyridyl-methyl-amine为配体，合成了一系列咪唑桥联Cu-Zn、Zn-Zn和Cu-Cu等有关19个新化合物，其中两个异双核〓Cu〓和〓〓配合物为Cu，Zn-SOD活性中心的模型化合物。2。

Of 549 isolates, 20 isolates (about 3.6% of the total isolates) showed significant activity against P. ultimum and 15 isolates (about 2.8% of the total isolates) against R.

结果表明，对终极腐霉、立枯丝核菌的半抑制稀释倍数（ID50）在10以上的活性菌株分别为20株（占总菌株的3.6%）和15株（占总菌株的2.8%）。

A total of five hundred and forty-nine isolates of endophytic fungi isolated from Taxus mairei were screened for the bioactivity targeted against Pythium ultimum and Rhizoctonia solani.

从南方红豆杉中分离到549株内生真菌，以终极腐霉Pythium ultimum、立枯丝核菌Rhizoctonia solani为靶标菌进行抗菌活性的筛选。

Solani with ID50 beyond 10. The isolate F0028, which has the highest inhibitory rate against P. ultimum (ID50 of 278±15.0) and R. solani (ID50 of 108±18.6) was identified as Aspergillus clavatonanicus.

其中矮棒曲霉Aspergillus clavatonanicus菌株F0028对这两种病原菌的活性最高（对终极腐霉、立枯丝核菌的ID50分别为278±15.0、108±18.6）。

The cytochemical localization of POD showed that the peroxidase was found in cells ofboth cultivars after inoculation. The activity of POD in resistant cultivar was higher than that innot only the uninoculated controls but also the inoculated susceptible ones and localized morewidely, such as localized in mesophyll cell wall, intercellular spaces, membranes of chloroplastand mitochondrion and vacuolar membrane. Whereas the POD in susceptible cultivar waslocalized mainly in cell walls but little in plasma membrane with a lower range and intensitythan that in resistant cultivar.

对过氧化物酶的细胞定位研究发现，无论抗病杨树还是感病杨树，接种后均发现细胞中有过氧化物酶反应产物，通过分析发现，毛白杨过氧化物酶的活性不仅明显高于未接种的对照，也明显高于接种处理后的北京杨，并且定位更广泛，在细胞壁、细胞间隙、叶绿体膜、线粒体膜及液泡膜上均有大量定位，而北京杨酶反应产物主要分布于细胞壁上，在细胞膜、核膜局部有少量定位，定位范围及强度均小于毛白杨。

HTERT is expressed in cancer cell lines despite promoter DNA methylation by preservation of unmethylated DNA and active chromatin around the transcription start site.

人端粒酶逆转录酶是一种核糖核蛋白酶，由端粒RNA和端粒酶蛋白组成的一种特殊逆转录酶，在激活端粒酶的过程中起限速作用，能以自身RNA为模板合成端粒序列以稳定端粒长度使细胞获得永生，也是人类端粒酶的活性中心，其表达是端粒酶活化的必须前题［2～4］。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
