Maternal and paternal origin differentially affect prosocial behavior and neural mechanisms in prairie voles.

This study tested the hypotheses that maternal and paternal effects differentially influence expression of their offspring's adult behavior and underlying neural mechanisms. We predicted that maternal influences would be greater than paternal influences on male offspring. We tested these hypotheses by cross-breeding two phenotypically-, behaviorally- and neuroanatomically-distinct populations of prairie voles (Microtus ochrogaster) from Illinois, which are highly prosocial, and Kansas, which are significantly less prosocial.

Bisphenol A alters the cardiovascular response to hypoxia in Danio rerio embryos.

The purpose of this study was to determine if the cardiovascular response to hypoxia was altered by the presence of bisphenol A (BPA) in Danio rerio embryos. It was expected that BPA exposure would affect cardiovascular parameters during hypoxia more than normoxia due to an interaction between BPA and the hypoxia-inducible factor (HIF-1α) pathway. We demonstrate that BPA exposure has a minimal effect during normoxia but can severely affect the cardiovascular system during a hypoxic event.
