纺锤

In this study, we found interesting two-cell stage embryos, which had a monopolar spindle in one blastomere and a bipolar spindle in the other during the second mitosis in a batch subjected to tetraploidization treatment.

在诱导四倍体过程中，我们发现了有趣的二细胞期胚胎现象，在第二次有丝分期间，它的一个分裂球中有一个单极纺锤体，二另一个有一个双极纺锤体。

We propose that SEPT7 forms a link between kinetochore localization of CENP-E and the mitotic spindle checkpoint.

同时我还发现SEPT的敲除会导致双极定向的染色体之间的张力减弱以及纺锤体检验点的激活，SEPT7可能将CENP-E的动点定位与纺锤体检验点信号的级联反应相联系起来。

During cell division,chromosome segregation is governed by the interaction of spindle microtubules with the kinetochore.

细胞分裂时，染色体的分离由纺锤体微管协同动点完成。从纺锤体两极发出的极间微管发生重排，在分开移向两极的染色单体之间形成严密整齐的动态结构：中心纺锤体。

In clinical application practice, the EEG sleep spindles have been found to be relative to the multifold pathology, so it is of an important clinical application value to detect EEG sleep spindles effectively.

在临床应用实践中已发现睡眠纺锤波与多种病症有关，因此，有效地检测出睡眠纺锤波具有重要的临床应用价值。

Result The spindles of oocytes were abnormal at 25℃ for 20 min, and disappeared at 25℃ for 30 min or at 4℃ for 10 min. 5, 10, 20 and 40 μg/ml Cytochalasin B for 2 h had no effects on the spindles of the oocytes. The spindles of oocytes were abnormal in 20 μmol/L colchicines for 1 h, and disappeared in 40 μmol/L colchicines for 1 h. The structure of spindles were perfect for 1-12 h when the oocytes were fixed in 4% paraformaldehyde.

结果］卵母细胞在25℃、20 min时纺锤体异常，25℃、30 min或4℃、10 min时纺锤体缺失；5、10、20和40μg/ml细胞松弛素B作用2 h未对纺锤体产生影响；卵母细胞在20μmol/L秋水仙素中作用1 h纺锤体异常，40μmol/L时作用1 h纺锤体缺失；在4%多聚甲醛中4℃条件下，卵母细胞纺锤体结构以固定时间为1~12 h效果较好。

Then the dominant species of each season was identified and the contribution of the abundance of these dominant species to total abundance was analyzed. The results indicate an obvious succession of dominant species. Centropages dorsispinatus, Acartia pacifica ca and Sagitta enflata were the primary dominant species in summer, however, Paracalanus aculeatus, Acartia pacifica and Paracalanus crassirostris were the major dominant species in autumn.

结果表明，两个季节优势种具有明显更替现象，夏季（6月）主要优势种为背针胸刺水蚤、太平洋纺锤水蚤和肥胖箭虫；秋季（9月）主要优势种是针刺拟哲水蚤、太平洋纺锤水蚤和强额拟哲水蚤。

The spindle tree grows the Brazil in South America plateau last, hope to go to far and far very as a the giant spindle in each put

纺锤树生长在南美洲的巴西高原上，远远望去很像一个个巨型的纺锤插在地里。

The spindle tree grows on South American Brazil highland , is looking for go and inserting very much like colossal every spindle within the field over.

纺锤树生长在南美洲的巴西高原上，远远望去很像一个个巨型的纺锤插在地里。

The results showed that after 2 h of culture in MEM the chromosomes of oocyte were seperated to form telophase I while a small spindle was observed around chromosomes of primary spermatocyte. However, two clear spindles were observed in the oocytes cultured in CB containing MEM. After further culture, the chromosomes of both primary spermatocyte and oocyte intermingled and formed one large spindle.

在无CB的培养液中培养的卵母细胞培养2小时后，卵母细胞已经进入第一次减数分裂的后期，染色体开始被拉向两极，而精母细胞的MI纺锤体才刚刚形成，虽然继续培养两者染色体可以合二为一并形成一个纺锤体，但是有些染色体发生滞后；当卵母细胞在含有CB的培养液中培养2小时后，在卵母细胞内形成两个相似大小的MI纺锤体，进一步培养形成一个大的纺锤体，染色体正常。

At the germinal vesicle stage, LGN is distributed both cytoplasmically and at the cortex.

LGN在小鼠卵母细胞内的过量表达会导致纺锤体伸长、纺锤体两极过度收拢以及纺锤体两极？

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
