Maternal stress alters endocrine function of the feto-placental unit in rats.
Prenatal stress (PS) can cause early and long-term developmental effects resulting in part from altered maternal and/or fetal glucocorticoid exposure. The aim of the present study was to assess the impact of chronic restraint stress during late gestation on feto-placental unit physiology and function in embryonic (E) day 21 male rat fetuses. Chronic stress decreased body weight gain and food in...
متن کاملFeto-placental ratio
The dimension of delivered placentae mirrors the cumulative conception to parturition. Placental weight is the gross summary of fetal growth under the influence of many extrinsic and intrinsic factors. Hence, the present study evaluated the influence of gestation, sex of the newborn, and parity on feto singleton newborn from a teaching hospital of North Karnataka, India. Data was collected from...
متن کاملInduction of cytochrome P4501A1.
Cytochrome P4501A1 is a substrate-inducible microsomal enzyme that oxygenates polycyclic aromatic hydrocarbons, such as the carcinogen benzo(a)pyrene, as the initial step in their metabolic processing to water-soluble derivatives. Enzyme induction reflects increased transcription of the cognate CYP1A1 gene. The environmental toxicant 2,3,7,8-tetrachlorodibenzo-p-dioxin is the most potent known ...
متن کاملEndocrine regulation of feto-placental growth.
Hormones are both growth stimulatory and growth inhibitory in utero. They regulate tissue growth and development by controlling the rates of cell proliferation, apoptosis and differentiation in many fetal tissues. They also signal the level of resources available for intrauterine growth to the fetal tissues and relay back to the placenta the degree of mismatch between the actual fetal nutrient ...
متن کاملMultiscale modelling of the feto-placental vasculature.
The placenta provides all the nutrients required for the fetus through pregnancy. It develops dynamically, and, to avoid rejection of the fetus, there is no mixing of fetal and maternal blood; rather, the branched placental villi 'bathe' in blood supplied from the uterine arteries. Within the villi, the feto-placental vasculature also develops a complex branching structure in order to maximize ...
