Using the Isolated Rat Placenta to Assess Fetoplacental Hemodynamics

Frontiers in Toxicology, 2022
Placental health is critical to fetal growth and maternal health during gestation. However, investigating placental flow in an ex-vivo isolated system where inflow is independently controlled has yet to be developed in the rat.

Lung-gut axis of microbiome alterations following co-exposure to ultrafine carbon black and ozone

Particle and Fibre Toxicology, 2023
Background Microbial dysbiosis is a potential mediator of air pollution-induced adverse outcomes. However, a systemic comparison of the lung and gut microbiome alterations and lung-gut axis following air pollution exposure is scant.

Maternal nano-titanium dioxide inhalation alters fetoplacental outcomes in a sexually dimorphic manner

Frontiers in Toxicology, 2023
The placenta plays a critical role in nutrient-waste exchange between the maternal and fetal circulations, thus functioning as an interface that profoundly impacts fetal growth and development. The placenta has long been considered an asexual organ, but,
