    QUESTION: Can an information prescription protocol be successfully integrated into a family medicine practice seeking to enhance patient education and self-management? SETTING: Milton Family Practice, an outpatient clinic and resident teaching site of the University of Vermont and Fletcher Allen Health Care, is located in a semirural area fifteen miles from main campus. OBJECTIVES: The objectives were to increase physicians\u27 knowledge and use of information prescriptions, sustain integration of information prescription use, and increase physicians\u27 ability to provide patient education information. METHODS: Methods used were promotion of the National Library of Medicine\u27s Information Rx, physician instruction, installation of patient and provider workstations, and a collaborative approach to practice integration. MAIN RESULTS: A post-intervention survey showed increased physician knowledge and use of the Information Rx protocol. Support procedures were integrated at the practice. CONCLUSIONS: Sustainable integration of Information Rx in a primary care clinic requires not only promotion and education, but also attention to clinic organization and procedures

    Aurora B Kinase Regulates the Postmitotic Endoreduplication Checkpoint via Phosphorylation of the Retinoblastoma Protein at Serine 780

    The phenotypic change characteristic of Aurora B inhibition is the induction of polyploidy. Utilizing specific siRNA duplexes and a selective small molecule inhibitor (AZD1152) to inhibit Aurora B activity in tumor cells, we sought to elucidate the mechanism by which Aurora B inhibition results in polyploidy. Cells treated with AZD1152 progressed through mitosis with misaligned chromosomes and exited without cytokinesis and subsequently underwent endoreduplication of DNA despite activation of a p53-dependent pseudo G1 checkpoint. Concomitant with polyploid cell formation, we observed the appearance of Rb hypophosphorylation, an event that occurred independently of cyclin-dependent kinase inhibition. We went on to discover that Aurora B directly phosphorylates Rb at serine 780 both in vitro and in vivo. This novel interaction plays a critical role in regulating the postmitotic checkpoint to prevent endoreduplication after an aberrant mitosis. Thus, we propose for the first time that Aurora B determines cellular fate after an aberrant mitosis by directly regulating the Rb tumor suppressor protein
