(wikipedia.org)
  • Placentas of these species also differ in their ability to provide maternal immunoglobulins to the fetus. (wikipedia.org)

Procedure2
  • Non-invasive prenatal testing (NIPT) by random massively parallel sequencing of maternal plasma DNA for multiple pregnancies is a promising new option for prenatal care since conventional non-invasive screening for fetal trisomies 21, 18 and 13 has limitations and invasive diagnostic methods bear a higher risk for procedure related fetal losses in the case of multiple gestations compared to singletons. (mdpi.com)

Predictors3
  • Multivariate regression analysis was used to determine significant predictors of logarithmically transformed fetal fraction and test failure. (medscape.com)

Urine3
  • Measure of cotinine in hair, blood, and urine permits the assessment of SHS exposure or active smoking. (biomedcentral.com)
  • These samples are stored in a "biobank" for future research and analyses of environmental exposures and include maternal urine, blood, serum, placenta, cord blood and the newborn's meconium. (mmm.edu)
  • I have also been able to process a few biological samples from both the clinic and the labor/delivery room: maternal urine, fetal urine, blood and placenta. (mmm.edu)
RBCs2
  • The heart begins to pump plasma around day 20, and on the next day, fetal red blood cells (RBCs), which are immature and nucleated, appear. (msdmanuals.com)
  • Fetal RBCs are soon replaced by mature RBCs, and blood vessels develop throughout the embryo. (msdmanuals.com)
Patterns1
  • [ 14 ] Doppler velocimetry measures hemodynamic flow of major fetal vessels, allowing comparison of the flow indices and patterns of normal and IUGR cases. (medscape.com)
Metabolism2
  • 2. The objectives of the study were to establish whether the placenta has a role in feto-maternal cholesterol metabolism through either synthesis or transplacental cholesterol flux. (portlandpress.com)
  • 7 What is new is an understanding that some of the body's memories of early undernutrition become translated into pathology-an unsurprising conclusion since numerous experiments in animals have shown that undernutrition for even brief periods in utero leads to persisting changes in blood pressure, cholesterol metabolism, insulin responses to glucose, and in a range of other metabolic, endocrine, and immune parameters.

Anemia3
  • Complete blood count (CBC): Anemia or polycythemia may be revealed that is not clinically apparent and thrombocytopenia will be known form CBC. (medscape.com)
  • The medium cerebral artery peak systolic velocity was 1.98 multiples of median, which indicated fetal anemia. (cdc.gov)
  • A fetal blood sample showed moderate anemia. (cdc.gov)

  • The cells in the placenta were also under more stress: they were less able to repair damage, and showed signs of inflammation. (tommys.org)
  • A key physiological response to hypoxia is the rise in levels of the hormone erythropoietin (EPO), which leads to increased production of red blood cells (erythropoiesis). (sciencedaily.com)
