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.

In vitro toxicoproteomic analysis of A549 human lung epithelial cells exposed to urban air particulate matter and its water-soluble and insoluble fractions

Particle and Fibre Toxicology, 2017
Background Toxicity of airborne particulate matter (PM) is difficult to assess because PM composition is complex and variable due to source contribution and atmospheric transformation.

Carbonyl Compounds Containing Formaldehyde Produced from the Heated Mouthpiece of Tobacco Sticks for Heated Tobacco Products

Molecules, 2020
Diverse harmful compounds can be emitted during the heating of tobacco sticks for heated tobacco products (HTPs). In this study, the generation of harmful compounds from the filter, instead of tobacco in tobacco sticks, was confirmed.

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,
