The long-term objective of this research is to develop a non-invasive approach for early
assessment of which patients are at high risk for future development of skeletal muscle
atrophy. The investigators hypothesize that the rate constant for the terminal portion of
the isotope decay curve following ingestion of a single oral dose of
deuterated-3-methylhistidine (D-3MH) provides an accurate measure of this increased risk and
that this rate constant can be measured non-invasively from timed spot urine samples. In
addition, the investigators hypothesize that ingestion of a meat-containing meal will
stimulate synthesis of skeletal muscle proteins to a greater extent than a
non-meat-containing meal.
