It was shown theoretically and experimentally that the placenta does not prevent entering of toxic chemical compounds to the fetal blood but vice versa provides their larger concentration than in the blood of the mother. Namely this may be related to an increase of the incidence of congenital abnormalities and other kinds of pathology in the newborn.

The purpose of this review is to serve as an update on congenital cytomegalovirus (CMV) evaluation and management for obstetrician-gynecologists and to provide a framework for counseling birthing people at risk for or diagnosed with a primary CMV infection or reactivation or reinfection during pregnancy. A DNA virus, CMV is the most common congenital viral infection and the most common cause of nongenetic childhood hearing loss in the United States. The risk of congenital CMV infection from transplacental viral transfer depends on the gestational age at the time of maternal infection and whether the infection is primary or nonprimary.

It has frequent association with tuberous sclerosis complex and may lead to heart failure, a potentially fatal condition. The use of transplacental sirolimus, a mTOR inhibitor, has emerged as a novel treatment in symptomatic fetal rhabdomyomas, there are, though, only few cases described.

This study focuses on the preparation and characterization of platelet membrane biomimetic nanocarriers (P-PLGA NPs) and investigates their interactions with the transplacental barrier. Poly (lactic-co-glycolic acid) nanoparticles (PLGA NPs) were coated with platelet membrane (PLTM) to construct P-PLGA NPs. Additionally, fluorinated polyethylenimine (F-PEI) was grafted onto PLGA NPs to prepare F-PEI-PLGA NPs, which were compared with PLGA NPs.

Studying iron transfer across trophoblast monolayers is crucial given the significance of iron in maintaining a healthy pregnancy and supporting fetal growth and development. To get insights into the complex mechanism of transplacental iron transfer, we developed a standardized Transwell®-based monolayer model using BeWo (clone b30) cells. Our proposed method is divided into two parts: 1.

Oral vaccines have several advantages compared with parenteral administration: they can be relatively cheap to produce in high quantities, easier to administer, and induce intestinal mucosal immunity that can protect against infection. These characteristics have led to successful use of oral vaccines against rotavirus, polio, and cholera. Unfortunately, oral vaccines for all three diseases have demonstrated lower performance in the highest-burden settings where they are most needed.
