In Brief: Advanced maternal age (AMA) is associated with adverse pregnancy outcomes, particularly those associated with placental dysfunction. This study showed that in a mouse model of AMA, male but not female fetuses had increased placental apoptosis and lipid peroxidation, as well as increased mitochondrial content, suggesting that the placentas of male fetuses in AMA mothers adapt to be able to deliver sufficient energy to the fetus.
Abstract: Although advanced maternal age (AMA) increases the risk of fetal growth restriction (FGR) and stillbirth, the mechanisms leading to the placental dysfunction observed in AMA are unknown.

This study investigated the effects of two emerging PFAS compounds, perfluorododecane sulfonic acid (PFDoDS) and perfluoro-4-ethylcyclohexane sulfonic acid (PFECHS), alongside legacy perfluorooctanesulfonic acid (PFOS), on gene expression in the liver, heart, and bursa of Fabricius from mallard ducklings (Anas platyrhynchos) exposed in ovo, simulating maternal transfer to the egg. These PFAS compounds were selected based on their detection in a declining sea duck species and concerns over their endocrine disruption potential. Farmed mallard eggs were injected with 80 ng/g of PFDoDS, PFECHS, or PFOS, reflecting concentrations at the upper end of those reported in wild bird eggs.

Background And Objectives: Alzheimer disease (AD) has a complex etiology with a strong genetic component. Despite mounting evidence that genetic risk effect sizes vary by population, most research on the genetics of AD has examined only data sets of individuals with European ancestry. In this study, we investigate the variable performance and transferability of polygenic risk scores (PRSs) by deriving a PRS from analyses of AD for various race and ethnic categories and applying this across groups using a -fold cross-validation approach.

Amphibians are sensitive biomonitors of environmental pollutants. However, existing research on per- and polyfluoroalkyl substances (PFASs) between different species of amphibians is limited. In the present study, water, soil, tiger frog (Hoplobatrachus chinensis) and forest frog (Rana chensinensis) samples were collected from Qingyuan County, South China.
