Characteristic DNA methylation profiles of chorionic villi in recurrent miscarriage [PDF]

Scientific Reports, 2022
Dysregulation of transcriptional programs that are tightly regulated by DNA methylation during placental and fetal development at different gestational stages, may cause recurrent miscarriage.

Case report: Prenatal diagnosis of rare chromosome mosaicism: discordant results between chorionic villi and amniotic fluid samples [PDF]

Frontiers in Genetics, 2023
Objective: We described a unique case of near-negative chromosome mosaicism in chorionic villi but complete monosomy X in amniotic fluid.Methods: Chorionic villus sampling and amniocentesis were performed separately in the first and second trimesters ...

Discordant structural chromosomal aberrations in chorionic villi and amniotic fluid leading to a formation of an isochromosome 21: a case report [PDF]

Molecular Cytogenetics, 2021
Background Fetoplacental discrepancies occur in approximately 1–2% of analyzed prenatal cases. They are typically due to confined placental mosaicism, where an aberration is observed in the placental cells but not found in the fetal cells.

Microplastic abundance in placental chorionic villi detected by pyrolysis-gas chromatography/mass spectrometry in cases of spontaneous miscarriage during early pregnancyResearch in context [PDF]

EBioMedicine
Summary: Background: There is widespread concern regarding the effect of microplastics (MPs) on human reproductive health. The accumulation of MPs and their potential effect on adverse pregnancy outcomes must be determined, particularly from the ...

Salmonella Typhi-Exposed Placentae: Chorionic Villi Histomorphology and Neonatal Birthweight [PDF]

Diseases
Background: Salmonella infections impose a substantial global health burden, with an estimated 95.1 million cases occurring annually. Pregnant women exhibit a heightened vulnerability due to pregnancy-specific immune adaptations and dietary habits that ...

Chorionic Villi Sampling [PDF]

Journal of Medical Genetics, 1987
The cytogenetic findings were analysed in a series of 500 pregnancies in which chorionic villi sampling was performed. In all cases a direct method was used, karyotyping being successful in 481 cases (96.2%). The main indication for sampling was maternal age over 36 (412 cases; 82.4%).

Progesterone decreased indoleamine 2,3-dioxygenase 1(IDO1) expression in early pregnancy chorionic villi and decidua

Autoimmunity, 2021
Indoleamine 2,3-dioxygenase1(IDO1) is one of the most important proteins in protect the embryos from the mother's immune system during pregnancy. However, the regulation of the protein expression at the maternal–foetal interface is not fully known.
