  • Maternal NanoTitanium Dioxide Inhalation Exposure Alters Placental Cyclooxygenase and Oxidant Balance in a Sexually Dimorphic Manner
    Maternal Nano-Titanium Dioxide Inhalation Exposure Alters Placental Cyclooxygenase and Oxidant Balance in a Sexually Dimorphic Manner
    Bowdridge EC ;
    Dunn AC
    2024/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    The placenta plays a critical role in nutrient-waste exchange between the maternal and fetal circulation, and thus impacts fetal growth and development. We have previously shown that nano-titanium dioxide (nano-TiO2) inhalation exposure during gestation decreased fetal female pup and placenta mass [1], which persists in the following generation [2] ...
