Assessing the Health Effects of Blast Injuries and Embedded Metal Fragments
University of Maryland at Baltimore (U.S. Department of Defense)
The primary objective of this project is to determine if the adverse health effects caused by embedded metal fragments can be predicted by changes in gene and microRNA expression in the surrounding muscle, urine or serum. The identification of such an early biomarker has important clinical implications in providing treatment to wounded warriors before the onset of adverse health effects.
