PLACENTAL TRANSFER OF NUTRIENTS DURING NORMAL AND PROLONGED GESTATION

Utero-placental transfer of octanoic, palmitic and linoleic acids during late gestation in gilts.

The transfer across the swine uterus and placenta of [1-14C]octanoic acid, [9,10(n)-3H]palmitic acid and [1-14C]linoleic acid was studied in five gilts and their fetuses during late gestation following a single bolus injection. Only trace amounts of labeled fatty acids were found in fetal plasma lipid. The highest fetal plasma lipid values were less than 1.2% of the peak maternal values. The co...

Placental mesenchymal dysplasia: chronological observation of placental images during gestation and review of the literature.

Placental mesenchymal dysplasia (PMD) is characterized by multiple hypoechoic vesicles which are similar to molar changes in the placenta; however, the process of such morphological changes of PMD during pregnancy has not been fully understood. We performed a review of all PMD cases published in English and identified 49 articles including 110 cases. With regard to the gestational age at which ...
