Estradiol was detected in Day 7 embryos and production increased approximately 50-fold (P<0.05) in medium recovered from Day 13 compared to Day 11 embryos and was greatest (P<0.05) from...
The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...

The diversity of attitudes held by California community college faculty about Student Learning Outcomes (SLOs) was studied. In twelve semi-structured interviews, faculty informants explained how their work has changed as a result of increased standardization and accountability measures, how they value those changes, and how they expect the profession to...
