非整倍体

Sperm morphology, DNA integrity and chromosome aneuploidy are the correlative factors to recurrent pregnancy loss.

精子形态、DNA完整性和染色体非整倍体率是反复自然流产的相关性因素。

The mitotic error rate in cleavage stage embryos was proven to be higher than the meiotic aneuploidy rate and as a consequence, the genome of a single blastomere is not representative for the genome of the other cells of the embryo.

在卵裂期胚胎这种有丝分裂的错误率被证明是高于减数分裂的非整倍体错误率，因此，单个卵裂球的基因不能代表其他胚胎细胞的基因组。

Consistent with predominantly stochastic gene expression and increased energy demands induced by aneuploidy,the "buffering" canalization processes in Down syndrome would be reduced thereby giving rise to increased variance to less stable developmental pathways such as proliferation.

与非整倍体诱导的主要预测基因的表达和增长的能量需要相一致，Down综合征中的"缓冲"的发育稳态过程将会减少，从而导致像增殖这样不稳定的发育途径的多样性增加。

Some problems related to "variation of chromosome number" in some teaching materials of genetics are presented in this article.

指出了高校有关遗传学教材"染色体数目变异"一节中，部分概念如单倍体、染色体组、非整倍体等存在的概念表述不清、前后矛盾等问题，并提出了相应的修改意见。

Objective:To examine the effects of ECRG2 in centrosome amplification and chromosome instability.

目的：非整倍体是肿瘤细胞的典型特征，是人类肿瘤染色体不稳定性的普遍形式。

To determine the true rate of aneuploidy and to elucidate the mechanism of aneuploidy,the sperms were decondensed for FISH analysis. It was found that the disomic frequencies of chromosome X was 0.208%. A new decondensation method was developed by trypsin treatment. The basic morphology of sperm was maintained.

为了解非整倍体的真实发生率及其发生机制，本文以X染色体α卫星DNA探针进一步检测出正常精子中X染色体的二体型频率为0.208％，同时，建立了一种保持精子基本形态的胰酶去凝聚的方法，为目前国内尚未开展的精子遗传物质结构的分子细胞遗传学研究，提供了新的手段。

Both single genes and chromosome segments may be hemizygous; for example, the X chromosome in the heterogametic sex, and whole chromosomes in aneuploids.

单独的基因和染色体片断都有可能是半合子。例如在异型性别中的 X 染色体以及非整倍体中的全部染色体。

Objective To study the expression of Mad2, the mitotic checkpoint protein, in esophageal cancer.

非整倍体是恶性肿瘤的显著特征，是染色体不稳定性的表现形式。

The occurrence of ABBB and BBB,but not ABB and aneuploids maybe demonstrates the distribution range of BB have contracted on the continent and Korean peninsula,AABB populations of plants with subglobose bulb have degenerated on the continent since Tertiary,and the mixed populations of BB and AABB are the relicts of populations on the continent,Korean peninsula and Cheju island.

此地出现ABBB和BBB，而未出现ABB以及非整倍体可能是说明自第四纪以来BB细胞型在大陆和朝鲜半岛的分布区正在收缩；大陆上AABB已经接近消失；而大陆、朝鲜半岛和济州岛的BB和AABB混合居群只是残遗。

The fluorescence in situ hybridization technique has established itself as a powerful improvement over conventional cytogenetic techniques and is now a well-accepted procedure for chromosome analysis and aneuploidy screening.

相对于传统的细胞遗传学方法，原位杂交技术具有很大的改进，已成为一种公认的染色体分析和非整倍体筛选技术。
