Diverging views on health information exchange organizations.

Introduction: Health information exchange (HIE) capabilities meet the demands for a more effective, efficient, and safer health care system. However, organizations and individual providers have pursued different strategies to meet their respective needs for HIE capabilities. Because effective information sharing is necessary to a learning health system, this study sought to explore the perceptions of different approaches' effect on key features of an effective health care system.

FOG-2 mediated recruitment of the NuRD complex regulates cardiomyocyte proliferation during heart development.

FOG-2 is a multi-zinc finger protein that binds the transcriptional activator GATA4 and modulates GATA4-mediated regulation of target genes during heart development. Our previous work has demonstrated that the Nucleosome Remodeling and Deacetylase (NuRD) complex physically interacts with FOG-2 and is necessary for FOG-2 mediated repression of GATA4 activity in vitro. However, the relevance of this interaction for FOG-2 function in vivo has remained unclear.
