    • The invention relates to a prenatal diagnostic method for the determination of a chromosomal aberration in a biological sample obtained from an individual, the method comprising: a) selecting for and isolating from said biological sample of an individual one or more target sequences of DNA molecules contained in the biological sample, wherein said target sequences comprise DNA sequences having consensus nucleosome binding regions; b)amplifying said selected target sequences; c) sequencing said amplified selected target sequences and allotting them to the chromosomes of the genome and identifying the unique allotted target sequences; d) determining a first amount for each of one or more first chromosomes identified on the basis of said unique allotted target sequences originating from said one or more first chromosomes; e) determining a second amount for each of one or more second chromosomes identified on the basis of said unique allotted target sequences originating from said one or more second chromosomes; and f) determining based on the said first and second amount a chromosomal abberation.
    • 本发明涉及用于确定从个体获得的生物样品中的染色体畸变的产前诊断方法,所述方法包括:a)选择并分离所述生物样品中的一种或多种包含的DNA分子的靶标序列 在生物样品中,其中所述靶序列包含具有共有核小体结合区的DNA序列; b)扩增所述选择的靶序列; c)对所述扩增的选择的靶序列进行测序并将它们分配到基因组的染色体并鉴定独特的分配的靶序列; d)确定基于源自所述一个或多个第一染色体的所述独特分配的靶序列鉴定的一个或多个第一染色体中的每一个的第一量; e)确定基于源自所述一个或多个第二染色体的所述独特分配的靶序列鉴定的一个或多个第二染色体中的每一个的第二量; 和f)基于所述第一和第二量确定染色体变异。

    • The invention concerns a system and method for determining embryo quality comprising monitoring the embryo for a time period, said time period having a length sufficient to comprise at least one cell division period and at least a part of an inter-division period, and determining the length of the at least one cell division period; and/or ii) determining the extent and/or spatial distribution of cellular or organelle movement during the cell division period; and/or iii) determining duration of an inter-division period; and/or iv) determining the extent and/or spatial distribution of cellular or organelle movement during the inter-division period thereby obtaining an embryo quality measure. Thus, the selection of optimal embryos to be implanted after in vitro fertilization (IVF) is facilitated based on the timing, duration, spatial distribution, and extent of observed cell divisions and associated cellular and organelle movement.
    • 本发明涉及一种用于确定胚胎质量的系统和方法,包括在一段时间内监测胚胎,所述时间段具有足以包括至少一个细胞分裂期和至少部分分期间的长度,并且确定 至少一个细胞分裂期的长度; 和/或ii)确定细胞分裂期间细胞或细胞器运动的程度和/或空间分布; 和/或iii)确定分隔期的持续时间; 和/或iv)在分隔期间确定细胞或细胞器运动的程度和/或空间分布,由此获得胚胎质量测量。 因此,基于观察到的细胞分裂的时间,持续时间,空间分布和程度以及相关的细胞和细胞器运动,便于在体外受精(IVF)后植入最佳胚胎的选择。
