Array comparative genomic hybridization and flow cytometry analysis of spontaneous abortions and mors in utero samples [PDF]

open access: yes, 2009
Background: It is estimated that 10-15% of all clinically recognised pregnancies result in a spontaneous abortion or miscarriage. Previous studies have indicated that in up to 50% of first trimester miscarriages, chromosomal abnormalities can be ...

Pathological and Genetic Analysis of Foetuses with Ultrasonogram Detected Congenital Anomalies: A Cross-sectional Study from Southern India [PDF]

open access: yesIndian Journal of Neonatal Medicine and Research
Introduction: Prenatal Ultrasonogram (USG) detects the majority of congenital anomalies, but a few cases may be missed due to multiple reasons. Hence, a detailed post-mortem evaluation of foetuses following termination of pregnancy can help to arrive at ...
