3063. Molecular MRI reveals atherosclerotic plaque fibrogenesis and stabilization in ApoE-/- mice with steatotic liver disease
B. Moon, Y-C Chen, I. Zhou, Y. Ning, E. Akam-Baxter, M. Le Fur, H. Ma, J. Weigand-Whittier, N. Rotile, P. Pantazopoulos, M. Tyros, C. Zhang, C. Farrar, J. Roberts Jr, Y. Iwamoto, D. Rohde, D. Sosnovik, K. Corey, M. Nahrendorf, P. Caravan
Cardiovascular Research Center, Massachusetts General Hospital and Harvard Medical School, Boston, United States
Impact:

An innovative fibrogenesis-targeted molecular MR probe revealed that reducing cholesterol resulted in atherosclerotic plaque stabilization even in a high-risk metabolic milieu of steatotic liver disease.

3064. Transmembrane pH imaging distinguishes glycolytic and oxidative phenotypes in gliomas
D. Coman, S. Mishra, S. Kurdi, J. Santana, F. Hyder
Yale University, New Haven, United States
Impact: Transmembrane pH gradient imaging can be used to distinguish between glycolytic and oxidative tumor phenotypes in glioblastoma. This technique could help design more efficient therapies, where targeting both phenotypes might be more effective than individually targeting each phenotype.
 
Computer Number: 41
