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]

open access: yesHuman 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

open access: yesInternational 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

open access: yesВісник 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 ...

Characterization of two marker chromosomes in a patient with acute nonlymphocytic leukemia by two-color fluorescence in situ hybridization [PDF]

open access: yes, 1993
A patient with acute nonlymphocytic leukemia (ANLL), M5b according to French-American-British (FAB) classification, showed monosomy 16, an extra 1p−, and a 21q+. These derivative chromosomes could not be defined by GTG-banding.

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

open access: yesBMC 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

Multicolour interphase cytogenetics: 24 chromosome probes, 6 colours, 4 layers [PDF]

open access: yes, 2011
From the late 1980s onwards, the use of DNA probes to visualise sequences on individual chromosomes (fluorescent in-situ hybridisation - FISH) revolutionised the study of cytogenetics.

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

open access: yesMolecular 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

open access: yesCell 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

open access: yesBMC 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.
