We studied the relationship between bilirubin concentrations in amniotic fluid and fetal blood in 68 non-hydropic rhesus d-alloimmunized anemic fetuses at first blood sampling. In these alloimmunized fetuses, the amniotic fluid/fetal blood ratio for bilirubin decreased from 0.09 at 28 weeks to 0.05 at 33 weeks. In normal fetuses, amniotic fluid/fetal blood ratios for bilirubin, and for albumin,...

The aim of the study was to compare sRAGE and esRAGE plasma levels in pregnant women with (A) threatened premature labor (n = 41), (B) preterm premature rupture of membranes (n = 49), and (C) preterm rupture of membranes at term (n = 48). The relationship between these and classic intrauterine infection markers and the latent time from symptoms up to delivery depending on RAGE's concentration w...

BACKGROUND Congenital cystic adenomatoid malformation (CCAM) is a rare hamartomatous cystic lesion. Open fetal surgery currently provides a potential therapeutic option for management of a fetus with CCAM diagnosis. CASE SUMMARY A 22-year-old G2P0 woman presented at (Equation is included in full-text article.)weeks' gestation for evaluation of a fetus with a left lung lesion and diagnosed as ...

Human fetal membranes play an important role in term and preterm labor and are responsive to steroids. We examined the expression of steroid receptor coactivators in fetal membranes obtained prior to and following labor at term. Proteins were localized by immunohistochemistry, Western analysis was carried out in nuclear extracts, and mRNA levels were determined by real-time RT-PCR. SRC-1, SRC-2...

Premature rupture of membranes (PROM) is a common obstetric complication frequently occurring with concomitant chorioamnionitis. The present study aimed to evaluate levels of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in serum and amniotic fluid in pregnant women with PROM and to compare sTREM-1 with the commonly used labor...

The only fetal cell membrane exposed to the mother in the mouse yolk sac placenta is the apical membrane of the endodermal epithelial cells. In yolk sac preparations in vitro, this apical membrane was exposed to reagents or cells in the incubation medium. By using several techniques we were not able to detect fetal major histocompatibility complex (MHC) antigens in this membrane. Immunoferritin...

Spontaneous intestinal perforation (SIP) of the newborn is a single commonly found in terminal ileum without distinct causes. These cases often associated with prematurity. The new COVID-19 pregnancy increased risk premature rupture membranes, preterm delivery, intrauterine fetal death (IUFD), and low birth weight (LBW). Here we report twin SIP that was born from Coronavirus-19 positive mother....

In order to clarify the potential role of IGF-I in fetal growth, the dynamics of IGF receptor were investigated in comparison with insulin receptor in human and rat fetuses. In humans, the serum levels of IGF-I measured by IGF-I radioimmunoassay after acid-ethanol extraction were significantly lower in fetuses than in adult controls. Conversely, serum insulin levels in fetuses were not indistin...
