The effect of a vanishing twin on first- and second-trimester maternal serum markers and ultrasound screening for aneuploidy [PDF]

open access: yesObstetrics & Gynecology Science, 2023
A vanishing twin (VT) is the early demise of a twin fetus. It is estimated to occur in 20–30% of pregnancies associated with assisted reproductive technology.

The genomic structure of a human chromosome 22 nucleolar organizer region determined by TAR cloning

open access: yesScientific Reports, 2021
The rDNA clusters and flanking sequences on human chromosomes 13, 14, 15, 21 and 22 represent large gaps in the current genomic assembly. The organization and the degree of divergence of the human rDNA units within an individual nucleolar organizer ...

Novel genetic resources associated with sucrose and stachyose content through genome-wide association study in soybean (Glycine max (L.) Merr.)

open access: yesFrontiers in Plant Science, 2023
The nutritional value of soybean [Glycine max (L.) Merr.] for animals is influenced by soluble carbohydrates, such as sucrose and stachyose. Although sucrose is nutritionally desirable, stachyose is an antinutrient causing diarrhea and flatulence in non ...

Investigation of Chromosomal Structural Abnormalities in Patients With Undiagnosed Neurodevelopmental Disorders

open access: yesFrontiers in Genetics, 2022
Background: Structural variations (SVs) are various types of the genomic rearrangements encompassing at least 50 nucleotides. These include unbalanced gains or losses of DNA segments (copy number changes, CNVs), balanced rearrangements (such as inversion

Homologies in human and Macasa fuscata chromosomes revealed by in situ suppression hybridization with human chromosome specific DNA libraries [PDF]

open access: yes, 1992
We established chromosomal homologies between all chromosomes of the human karyotype and that of an old world monkey (Macaca fuscata) by chromosomal in situ suppression (CISS) hybridization with human chromosome specific DNA libraries.

Clinical manifestations of chromosomal anomalies and polymorphic variations in patients suffering from reproductive failure

open access: yesJournal of Human Reproductive Sciences, 2020
Background: Human reproduction is the most intricate event as ~ 20% of human pregnancies end in miscarriages for which chromosomal anomalies are a common factor.

Порівняльний аналіз каріотипу нової лінії клітин людини 4BL в умовах тривалого культивування. Плоїдність хромосомного набору [PDF]

open access: yes, 2013
Тривале культивування клітин людини, в тому числі стовбурових, може призвести до істотної трансформації каріотипу та генетичної нестабільності. Метою даної роботи було порівняльне цитогенетичне дослідження каріотипу нової лінії стовбурових клітин людини ...

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
