MORPHOMETRIC PARAMETERS OF PLACENTAL CHORIONIC VILLI IN LABOR AFTER 40 WEEKS

Неонатологія, хірургія та перинатальна медицина
The placenta is the main organ that ensures the vital activity of the fetus during pregnancy. Studying the morphometric characteristics of chorionic villi allows us to better understand the changes that occur in the placenta in late pregnancy.

Vaccinations During Pregnancy Protect the Mother–Infant Dyad and Are Generally Safe

Acta Paediatrica, EarlyView.
ABSTRACT Aim Vaccination in pregnancy has a critical impact on mothers, foetuses and infants. The aim of this paper was to summarise key points presented by experts attending the 12th Maria Delivoria‐Papadopoulos Perinatal Symposium in March 2025 and further expand and update them.

High‐elevation adaptation and gestational hypoxia jointly shape vascular development in a rodent placenta

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how environmental hypoxia and genetic adaptation to high altitudes jointly impact the development of the placental exchange surface in ways that might protect fetal growth potential. We used wild‐derived, lab‐born North American deer mice (Peromyscus maniculatus) from low‐elevation and high‐elevation environments (

PFAS exposure during pregnancy: Implications for placental health and functioning

Environment International
Background: Animal studies have linked prenatal poly- and perfluoroalkyl substances (PFAS) exposures with impaired placental structure and function. In humans, only few studies have investigated such associations.

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

First trimester placental villi grown on Matrigel to obtain invasive cytotrophoblasts (iCTBs) in vitro.

, 2023
(A, B) Representative images of iCTBs outgrowth from a 6.4wk placental villi culture explants for 3 days. (C) Immunostaining of first trimester placenta villi culture explant showed most iCTBs are positive for Cytokeratin-7 (CK-7). (D) CTBs on the tip of

Physiological and anatomical determinants of placental drug transfer

The Journal of Physiology, EarlyView.
Abstract figure legend Fetal exposure to pharmaceuticals and their subsequent clearance back to the maternal circulation are governed by placental transfer. Passive diffusion down a maternal‐to‐fetal concentration gradient is the primary route of fetal drug exposure, with specific compounds undergoing transporter‐mediated transfer.

Implications of Intermittent Fasting on Placental Function [PDF]

Introduction: Women who partake in Ramadan during pregnancy have lower placental weights. Intermittent fasting (IF) impacts upon asynchronous dietary cues and the entrained sleep cycle.

An exploratory study on the placental efficiency, histomorphometric characteristics, hormonal shifts, and oxidative stress in dromedary camels with dystocia

Frontiers in Veterinary Science
The study investigated placental efficiency, histomorphometry, and hormonal concentrations (progesterone, estradiol 17β, and cortisol) alongside oxidative stress indicators (malondialdehyde (MDA) and total antioxidant capacity (TAC)) and performed ...

A primary cell‐based fluidic co‐culture model to investigate drug transport across the human placenta

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of a flow‐driven in vitro model of the human placental barrier designed to study transport processes during pregnancy. The model recreates key features of the maternal–fetal interface, enabling the investigation of how nutrients and therapeutic compounds cross the placental barrier under physiologically ...
