PubMed摘要：我们在此提出证据，证实鸣鸟前脑区——前新纹状体的侧巨细胞核在学习鸣叫中，存在长期突触可塑性。

The efficiency of IRES-dependent translation is concerned with the infectivity of viruses, but whether the IRES is concerned with neurotropism or not is still controversial.

另一方面，病毒IRES与核醣体的结合需要细胞中IRES trans-acting factors的参与，而目前对肠病毒71型ITAF的了解仍然有限。

Sbp1p is a nucleolar single-strand nucleic acid binding protein that we found associated with the ribosome.

A new picorna-like virus was isolated from dead Evtropis oblique larvae deceased from NPV infection. Electron microscopic observations of purified virions were non-enveloped isometric particles with diameter of 26nm. The virions contain two capsid proteins: 31.5kDa and 28.8kDa, the amount of later is 2.5 times more than that of the former. Analysis of 3′terminal sequence of EoPV clone identified that it can encode RdRp and has eight conserved motifs. Homology analysis shows that it is closely related to Perina nuda picorna-like virus.

从核型多角体病毒感染致死的茶尺蠖幼虫尸体中分离到一株微小RNA病毒透射电镜观察纯化的病毒粒子为无囊膜、无表面特征、直径约26nm的球状颗粒。16%的SDS-PAGE显示它有两个分子量为31.5 kDa和28.8 kDa的衣壳蛋白，后者的含量是前者的2.5倍。3′端克隆序列分析表明EoPV基因组3′有poly尾，编码RNA聚合酶，含有微小RNA病毒RNA聚合酶的八个保守基序，同源性分析表明它与榕透翅毒蛾微小RNA病毒亲缘关系最近。

Four male sterile lines of different nuclei genotypes with the same cytoplasm of Aeglops bicornis ,msbicorj-83 (37 65. ms-yanshi 9^ ms-80 (6) and ms-90-110, were selected as the materials in the study on gene location of B -type cytoplasmic male sterile lines by using monisomic analysis and nullisomic -tetrasomic analysis methods.

本研究选用4个同质异核二角型不育系ms-83(37)65、ms-偃师9号、ms-80(6)及ms-90-110为材料，采用单体和缺四体两种方法对二角型不育系进行了育性基因定位。

Their shapes were diversiform such as nummular, elliptic and oval etc. Positive neurons had one or several tubers and its axon was short. This experimentation results showed that development level of eNOS immunopositive neurons approach the adult rabbit when it is a young rabbit.

eNOS阳性神经元呈棕褐色，免疫阳性物质主要位于胞浆内，胞浆染色均匀，胞核处着色浅；神经元胞体形态各异，有圆形、卵圆形、椭圆等多种形状，神经元突起有一个或者数个，轴突较短。

The sequences of internal transcribed spacer regions of nuclear ribosomal DNA of 9 samples of Nymphaea and related water lilies as outgroups were sequenced and assembled with the sequences in GenBank to analyze the specific and infraspecific relationships.

本文测定了睡莲属9个样品的核核糖体DNA ITS区序列，结合GenBank中获得睡莲类ITS序列，分析了这些样品间的亲缘关系。

Analysis of mitochondrial DNA composition of the panda-rabit cloned embryos found that mitochondria from both panda somatic cells and rabbit ooplasm co-existed in early blastocyst, but mitochondria from rabbit ooplasm decreased and those from panda donor cells dominated in early fetuses after implantation.

结果显示，应用卵裂球电融合方法可以制作一系列的多倍体胚胎；小鼠囊胚的形成与胚胎中的细胞数目无直接关系，卵裂球的电融合和染色体数目的增加不会改变胚胎的发育进程；而胚胎细胞中的核／质比可能是控制胚胎囊胚化的一个重要因素。

A simple one-step procedure was described for the synthesis of mesoporous monolith and composite sphere, in which hydrolyzation of tetraethyl orthosilicate and polymerization of urea with formaldehyde occurred at the same time.
