The PACAP/PAC1 Receptor System and Feeding.

Pituitary adenylyl cyclase activating polypeptide (PACAP) belongs to the vasoactive intestinal polypeptide (VIP)/secretin/glucagon superfamily. PACAP is present in two forms (PACAP-38 and PACAP-27) and binds to three guanine-regulatory (G) protein-coupled receptors (PAC1, VPAC1, and VPAC2). PACAP is expressed in the central and peripheral nervous systems, with high PACAP levels found in the hypothalamus, a brain region involved in feeding and energy homeostasis.

EXAMINING THE EFFECTOF LANGUAGE-BASED INSTRUCTIONAL INTERVENTIONS ON ELL AND NON-ELL LANGUAGE PRODUCTION AND TASK-ORIENTED BEHAVIOR IN ELEMENTARY MATH, SCIENCE, AND SOCIAL STUDIES CLASSROOMS.

As the population of K-12 English language learners (ELLs) grows, teachers are challenged to employ strategies that efficiently promote content-learning and language-learning. This paper reports an action research project investigating the effects of three consecutive instructional interventions on student language production at a suburban elementary school. Teachers identified a problem of practice, consulted scholarship for intervention design, and conducted collaborative action research in science, mathematics, and social studies classes.
