Summary
Second trimester amniotic fluid transferrin and uric acid levels predict infant birth weight and gestational age. These biomarkers may indicate early fetal development, aiding in predicting birth outcomes.
Area of Science:
- Biochemistry
- Obstetrics
- Fetal Development
Background:
- Amniotic fluid composition offers insights into fetal well-being.
- Identifying biomarkers for predicting birth outcomes is crucial in prenatal care.
Purpose of the Study:
- To determine if second trimester amniotic fluid protein and uric acid concentrations correlate with and predict infant birth weight and gestational age.
Main Methods:
- Collected and analyzed amniotic fluid samples (n=230) from mothers undergoing amniocentesis.
- Quantified albumin, IgG, transferrin, and uric acid using capillary zone electrophoresis (CZE).
- Gathered maternal and infant data including birth weight and gestational age.
Main Results:
- Higher transferrin concentrations were observed in preterm infants.
- Transferrin negatively correlated with gestation length; uric acid positively correlated with gestational age in spontaneous vaginal delivery infants.
- Uric acid significantly predicted infant birth weight.
Conclusions:
- Second trimester amniotic fluid transferrin and uric acid levels are associated with birth outcomes.
- These amniotic fluid components may serve as potential biomarkers for early fetal development assessment.

01:15Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
