Bcl-2 protein was abundantly immunolocalized in syncytiotrophoblasts in normal term placentas, but least abundant in term placentas complicated by severe preeclampsia or intrauterine growth retardation.
The expression of VEGF and VEGFR-2 mRNAs was significantly lower in normal term or diabetes type-I placenta compared to human endometrium (P≤0.01).
The apoptosis positive rate of syncytiotrophoblast nuclei in severe preeclamptic and intrauterine growth retardation term placentas was significantly higher than that in normal term placentas (severe preeclampsia, P <.001; intrauterine growth retardation, P <.01).
To describe cardiac function, cerebral regional oxygen saturation (rSO2), and cerebral blood flow (CBF) that correspond to changes in arterial oxygen saturation (SaO2) in normal term neonates immediately after birth and after the transition.
Study design: We measured mRNA expression of vascular endothelial growth factor (VEGF), angiopoietin 1 and 2 (Ang-1 and Ang-2), their receptors VEGFR-1, VEGFR-2, Tie-2, fibroblast growth factor 2 (FGF-2), and its receptor FGF-2R in placental tissue of diabetes type-I patients, in normal term placenta, and endometrium of non-pregnant women by real time reverse transcriptase PCR.
Another limitation of the present study is that we did not perform DTI in normal term infants.
This is very important from the point of view of the metabolic pathogenesis of RP in cows which have their parturition in normal term.
Can we "grow" in normal terms?
Placentas stained for IL-1Ra revealed expression within the syncytiotrophoblast layer in the terminal villi, the fetal cell layer in direct contact with maternal blood, as well as in cytotrophoblast in both normal term and RFM tissue (Fig. 4a, black arrowheads).
In preterm infants, the gland is taller than in normal-term infants, even when correcting for gestational age.
