FISH analysis for chromosomes 13, 16, 18, 21, 22, X and Y in all blastomeres of IVF pre-embryos from 144 randomly selected donated human oocytes and impact on pre-embryo morphology [PDF]

Human Reproduction, 2003
The data are compiled from two multicentre, prospectively randomized studies on the effect of follicular fluid meiosis-activating sterol (FF-MAS) on human oocytes. The donated oocytes were exposed either to test doses of FF-MAS or to control solutions.

Role of Gene Length in Control of Human Gene Expression: Chromosome-Specific and Tissue-Specific Effects

International Journal of Genomics, 2021
This study was carried out to pursue the observation that the level of gene expression is affected by gene length in the human genome. As transcription is a time-dependent process, it is expected that gene expression will be inversely related to gene ...

Change in the karyotype of the embryo as a cause of spontaneous abortion in the first trimester

Вісник Харківського Національного Університету Імені В.Н. Каразіна: Серія Біологія, 2021
Currently, one of the most actual health problems in the world is the problem of a spontaneous abortion. Chromosomal abnormalities are one of the main reasons of early abortion, stillbirth or the birth of a child with multiple congenital malformations ...

Chromosome breakpoint distribution of damage induced in peripheral blood lymphocytes by densely ionising radiation [PDF]

, 2006
Purpose: To assess the chromosomal breakpoint distribution in human peripheral blood lymphocytes (PBL) after exposure to a low dose of high linear energy transfer (LET) α-particles using the technique of multiplex fluorescence in situ hybridisation (m ...

Chromosome painting in three-toed sloths: a cytogenetic signature and ancestral karyotype for Xenarthra

BMC Evolutionary Biology, 2012
Background Xenarthra (sloths, armadillos and anteaters) represent one of four currently recognized Eutherian mammal supraorders. Some phylogenomic studies point to the possibility of Xenarthra being at the base of the Eutherian tree, together or not with

Chromosome assignment of two cloned DNA probes hybridizing predominantly to human sex chromosomes [PDF]

, 1984
In situ hybridization experiments were carried out with two clones, YACG 35 and 2.8, which had been selected from two genomic libraries strongly enriched for the human Y chromosome.

Human ring chromosome registry for cases in the Chinese population: re-emphasizing Cytogenomic and clinical heterogeneity and reviewing diagnostic and treatment strategies

Molecular Cytogenetics, 2018
Background Constitutional ring chromosomes are rare orphan chromosomal disorders. Ring chromosome syndrome featuring growth retardation and mild to intermediate intellectual disability is likely caused by the dynamic behavior of ring chromosome through ...

Quality of Blastocysts Created by Embryo Splitting: A Time-Lapse Monitoring and Chromosomal Aneuploidy Study

Cell Journal, 2020
Objective: The aim of this study was to screen the potential of human embryos to develop into expanding blastocysts following in vitro embryo splitting and then assess the quality of the generated blastocysts based on chromosomal characteristics and ...

Chromosome painting in the manatee supports Afrotheria and Paenungulata

BMC Evolutionary Biology, 2007
Background Sirenia (manatees, dugongs and Stellar's sea cow) have no evolutionary relationship with other marine mammals, despite similarities in adaptations and body shape.
