Advanced practice nursing students: pilot test of a simulation scenario.

In the current educational environment, increasing numbers of advanced practice nursing (APN) students compete for decreasing numbers of clinical sites where patient safety is paramount. Clinical simulations with high-fidelity human patient simulators provide APN students opportunities to demonstrate clinical skills and judgment in a safe supportive environment. Development, implementation, and preliminary evaluation of a scenario for APN students are discussed.

Induction of cellular growth by the axon guidance regulators netrin A and semaphorin-1a.

Although neurite outgrowth has been linked to axon guidance regulators, the effects of guidance molecules on cellular growth are not well understood. Use of the Drosophila wing imaginal disc, an epithelial tissue and a well-characterized system for analysis of cellular growth regulation, permits analysis of the impacts of guidance molecules on cellular growth in a setting in which axon guidance is not a confounding factor. In this investigation, the impacts of Netrin A (NetA) and Semaphorin-1a (Sema1a) signaling on cellular growth are examined during wing development.
