The Association between Low Fetal Fraction of Non-Invasive Prenatal Testing and Adverse Pregnancy Outcomes for Placental Compromise.

(1) Background: Non-invasive prenatal testing (NIPT) is a screening test for fetal aneuploidy using cell-free fetal DNA. The fetal fragments (FF) of cell-free DNA (cfDNA) are derived from apoptotic trophoblast of the placenta. The level of fetal cfDNA is known to be influenced by gestational age, multiple pregnancies, maternal weight, and height.

Evaluation of fetal and neonatal outcomes after ingestion of Cnidium root (Cnidium officinale Makino) during pregnancy.

Cnidium officinale Makino is a perennial plant, a member of the Umbelliferae family. Cnidium root has traditionally been used as a medicinal herb. It has analgesic, antiinflammatory, antipyretic, antibacterial, antispasmodic, vasodilatory, hypertensive, and sedative effects.

Functional analysis of cell-free RNA using mid-trimester amniotic fluid supernatant in pregnancy with the fetal growth restriction.

The prediction and monitoring of fetal growth restriction (FGR) fetuses has become with the use of ultrasound. However, these tools lack the fundamental evidence for the growth of fetus with FGR excluding pathogenic factors.Amniotic fluid samples were obtained from pregnant women for fetal karyotyping and genetic diagnosis at 16 to 19 weeks of gestation.
