NIH/NCRR Biomedical Informatics Research Network (BIRN) Emory Univ. Yerkes NPRC Mediator architecture Knowledge-based mediation Integrated view definitions
Biomedical Informatics Research Network (BIRN) What is data mediation? The Biomedical Informatics Research Network (BIRN) will use a “mediator architecture” to link multiple databases with different schemas, maintained at different research institutions into a data federation. This type of architecture is flexible, scalable, and powerful. It allows individual researchers to manage their own data in databases tailored to meet their specific needs. Those searching the system, however, will see the BIRN Data Federation as if it were a single database. Queries will be issued against the “mediator”, a virtual database that combines the individual data sources in meaningful ways. This combination is achieved using “Integrated View Definitions” which describe how the mediator represents the source databases. A user will submit a query to the mediator (or more precisely, to one of the integrated views the mediator can expose). The mediator will then parse the query and submit one or more queries to the relevant data sources.

Transgenic Monkeys • Born with mutant gene, e.g., over-expression of protein • Short time to expression • Treatment interventions • Behavioral assessments
Biomarkers and Brain Imaging Amyloid plaques PET scan
Vaccines for Noninfectious Diseases • Elan vaccine, AN-1792 • Designed to attack and clear out plaques. • Mice immunized at a young age were protected from plaque deposits; in animals that already had deposits, they were halted and in some cases reversed. • Clinical trials stopped; inflammation of brain. • Deposits of amyloid in blood vessel walls in old monkeys.
Sequencing of Human and Nonhuman Primate Genomes (Chimpanzee, Rhesus monkey…) • Yerkes Chimpanzee, Clint • Differences in genome important; Similarities in genome important. • Where and when are genes important for memory function expressed? • How are cells expressing these genes influenced by the environment? New finding of structural variation in normal subjects. Individual differences? • Where do we spot points of vulnerability that can make the difference between healthy memory and diseases that impair memory?
