Somaclonal variations analysis on mixoploid hybrid plant BI-1 showed that percentage of cells with 2n=25, 26 decreased and percentage of cells with 2n=29 ascended.Chromosome segments of I.

并对混倍体杂种BI-1的无性系变异进行了分析，发现染色体数目为25、26的细胞比例呈明显下降趋势，而染色体数为29的细胞比例明显上升，其他染色体数目的细胞比例处于动态变化之中。

The extensive variation in chromosome number in root tip cells of three Chinese cabbage-cabbage monosomic alien addition lines with 21 chromosomes, 6-2-4, c-2-4 and d6, was obsevered after vegetative propagation multi-generations. The chromosome number varied from 17 to more than 50. The 25S rDNA signals were very complex in the three different clones.

染色体数目为21条的3个大白菜-结球甘蓝单体异附加系6-2-4、c-2-4和d6，在无性繁殖多代后根尖细胞均出现了广泛的染色体数目变异的现象，变异范围从17条到50多条不等，25S rDNA在这些无性系的FISH杂交信号较为复杂。

We observed that the nestin positive cells distributed mainly near the internal limiting membrane and mantle layer of neuroepithelium. The positive cells arranged regularly along the neuroepithelial layer. After RA-treated, it was found that the number of neural stem cells reduced, especially at the eighth day of embryo p

RA作用后Nestin阳性细胞数目均普遍低于正常组；尤其在E8.5d时阳性细胞数目减少最为显著 p CDK5相似，于胚胎E14d已见其强阳性表达，成年期、老年期表

It has been demonstrated that, as an indicator of the fragmentation of political system, the effective number of candidates running under the single nontransferable vote system converges to M+1, where M is district magnitude.

关於「单记非让渡投票」选制之下的有效政党数目，曾有学者延伸杜弗杰定律，主张在应选名额为M的选区中，有效参选人数目应趋近於M+1。

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。

Large though the sum seems in European terms, it pales in comparison to sums raised in the US.

尽管以欧洲人的眼光来看，这是一笔很大的数目，但若与美国商学院的筹资数目相比，它就要黯然失色了。

It identifies those communities by way of the multidimensional eigenvectors of network's connection matrices, and then the effects of key parameters on the division results are analyzed through simulation so as to determine the parametrical values which make sure that the results of division are optimum.

利用网络连接矩阵的多维特征向量划分网络社团，通过仿真实验分析关键参数对划分效果的影响，从而确定使得划分结果最优的参量值，并综合多维特征量阈值和社团数目两方面的因素决定被划分的社团数目。

The few surviving animals (possibly including only 23 reproductively active females) face a number of hazards throughout their range. A complete copy of the report can be found at www.iucn.org

数目稀少的灰鲸（大概只有23头具有生殖能力的母鲸）处于种群数目危险的范围内，完整的报告可以登陆IUCN 的网站获得www.iucn.org

Results: nk 4r immunoreactivity was found extensively localized in neuronal somata and neurite of cerebral cortex, and mainy in layer ⅲ,ⅴ. double labeling experiments confirmed that 100% nk 4r immunoreactive neurons co expressed neun, but not gfap.

结果：nk 4r免疫阳性产物在皮层的锥体细胞层分布最多，在皮层内、外颗粒层、多形层也广泛分布，其阳性产物表达于神经元胞体和突起上，免疫荧光双标结果观察到nk 4r与神经元胞核特异性标记物neun共存（100%，146/146，双标细胞数目/nk 4r阳性细胞数目），且不与星形胶质细胞标记物gfap共存。

Chromosome observation of the male sterile line and fertile line, parents of hybrid combination and F1 indicated that the chromosome number of the male sterile line is the same as that of fertile line 2n=2x=24; Pollen parent (Tagetes putula PHBO029) is tetraploid 2n=4x=48; the F1 is triploid 2n=3x=36 with hybrid vigor.

通过对不育系、正常可育系以及杂交组合父母本、子一代的染色体数目观察发现：万寿菊雄性不育系的染色体数目与正常可育系相同，均为2n=2x=24；孔雀草PHBO029为四倍体2n=4x=48，它与万寿菊不育系杂交、其杂种为具有杂种优势的三倍体2n=3x=36。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
