Is β-catenin required in the neural crest and mesencephalon for pituitary gland organogenesis?
β-catenin in the Wnt1 expression domain, including the neural crest, plays a critical role in regulation of pituitary gland growth, development, and vascularization.
Experienced emergency physicians were both faster and more accurate than residents. Instructions to proceed quickly and interruptions had a small effect on response time but no effect on accuracy.
