Comprehension of maternal-fetal exchange
Endocrine, 20021 During the twentieth century, major scientific studies focused on a discovery the etiology and treatment of adult pathologies and, to a lesser extent, neonatal pathologies, in order to provide better health for our society. Newborns represent our future, so it is important to ameliorate fetal and newborn health.

Maternal-Fetal Exchange of 59 Fe: Radiation Dosimetry and Biokinetics in Human and Sheep Studies
Radiation Research, 1973The estimation of the absorbed radiation dose to the human fetus from59 Fe administered to the mother requires information on the biokinetics of the59 Fe within the mother and fetus. For the first part of pregnancy, up to about 24 wk gestation, information from studies done on women receiving therapeutic abortions is available.

The expression of calcitropic genes and proteins was localized within murine placenta during late gestation (the time frame of active calcium transfer) with an analysis of several gene-deletion mouse models by immunohistochemistry and in situ hybridization. Parathyroid hormone-related protein (PTHrP), the PTH/PTHrP receptor, calcium receptor, calbindin-

AbstractThe placenta establishes a maternal–fetal exchange interface to transport nutrients and gases between the mother and the fetus. Establishment of this exchange interface relies on the development of multinucleated syncytiotrophoblasts (SynT) from trophoblast progenitors and defect in SynT development often leads to pregnancy failure and impaired

Basic Concepts of Maternal-Fetal Amniotic Fluid Exchange: Their Relevance to Fetal Therapeutics
Pediatric Clinics of North America, 1981Traditional concepts of fetal pharmacologic therapy have consisted of treating the mother in order for the fetus to derive secondary benefit. However, amniotic fluid physiology has been the focus of increasing interest recently since this fluid sac may provide more direct pharmacologic access to the fetal compartment.

The placenta provides a maternal-fetal exchange interface that maximizes the diffusion of gases, nutrients, and wastes. However, the placenta also may permit diffusion of lipid-soluble steroid hormones that influence processes such as sex-specific fetal development and maternal pregnancy maintenance. In mammals, placental steroid metabolism contributes

The establishment of pregnancy results from the interaction between the trophoblast and maternal tissues. Evolutionarily, the yolk sac (YS) is the only fetal membrane present in all vertebrate taxa. In mammals, it results in the development of the YS placenta, which is responsible for maternal–fetal exchange in the beginning of gestation. Its functions

The influence of protein restriction on the maternal-fetal transfer of nutrients was explored in rats fed a 6% casein diet. At days 20 and 21 of gestation, 1 muCi/100 g of body weight of 14C-alpha-amino isobutyric acid was injected inthe maternal circulation of controls fed a 27% casein diet, and experimental rats.

[Analysis of maternal-fetal exchange in the study of environmental exposure to lead].
Archivio per le scienze mediche, 1983398 women at various stages of pregnancy and living in two areas subject to different levels of atmospheric pollution were examined. Blood samples were taken from about 200 women and their funiculi at the moment of parturition. The results showed a difference in lead concentrations in the blood and in the ratio of mother and funicular lead ...

Maternal-fetal transfer of glucose and methyl alpha-D-glucopyranoside (AMG) was studied in rats fed either a 6% or a 27% casein diet. On day 21 of pregnancy 3H-labeled glucose and 14C labeled AMG were injected into the maternal circulation of both groups of dams and concentration of tritium and 14C in maternal plasma, placentas and fetuses were ...
