Many highly efficient methods exist which enable transgenic flies to contribute to diagnostics and therapeutics for human diseases. In this study, researchers describe a drug-based genetic platform with four selection and two counterselection markers, increasing transgenic efficiency by more than 10-fold compared to established methods in flies. Researchers also developed a plasmid library to adapt this technology to other model organisms. This highly efficient transgenic approach significantly increases the power of not only Drosophila melanogaster but many other model organisms for biomedical research.

Effects of Early Daily Alcohol Exposure on Placental Function and Fetal Growth in a Rhesus Macaque Model

In a rhesus macaque model for chronic prenatal alcohol exposure, daily consumption during early pregnancy significantly diminished placental perfusion at mid to late gestation and significantly decreased the oxygen supply to the fetal vasculature throughout pregnancy. These findings were associated with the presence of microscopic placental infarctions. Although placental adaptations may compensate for early environmental perturbations to fetal growth, placental blood flow and oxygenation were reduced, consistent with the evidence of placental ischemic injury that persisted throughout pregnancy.
