  1. Achievements & Developments of Metabolic Phenotyping and In Vivo Imaging Cores Thomas Balon, Ph.D. tombalon@bu.edu BUMC Faculty Meeting December 1, 2015

  2. Introduction • Other cores • Cellular Imaging Cores – Mike Kirber mkirber@bu.edu • Immunohistochemistry – Natalie Bitar natbitar@bu.edu • Metabolomics – Anqi Zhang • anqi@bu.edu • High Throughput Screening Core - TBA • Analytical Instrumentation Core – Lynn Deng lynndeng@bu.edu later presentation Matt Aumau115@bu.edu

  3. What We Have What Is it Good For • Determination of • total body fat • lean mass • body fluids • total body water • in live rats/mice up to 700 grams • Instrumentation-EchoMRI-700™ Old vs. New System • larger range of weights with • greater precision (smaller rodents) • faster resolution times

  4. Instrumentation-EchoMRI-700™ • Usage • Calendar year Minutes of use 2012 1500 2013 2395 2014 2792 2015 (11 Mo.) 3138 • Challenges - Major user is leaving (44% usage loss) • Resolution - 4 new users & Contract with Harvard for Carcass analysis

  5. Instrumentation-CLAMS • measurement of metabolic rate (caloric expenditure) • determination of substrate used (fat / carbohydrate) • assessment of activity patterns • greater sensitivity (sleep detection)

  6. Instrumentation-CLAMS • Usage • Calendar year Days of use 2012 29 2013 60 2014 43 2015 (11 Mo.) 50 • Challenges - Major user is leaving (74% usage loss) • Resolution -2 new users & Characterization of 2 new strains

  7. Partial List of Publications using Echo and CLAMS 1. Kleckner AS, Wong S, Corkey BE. 2015.
