               release of a protein produced by the
     body during the inflammation process could
     result in improved treatments for patients
     suffering post-operative infection, particularly
     following cardiopulmonary bypass surgery.
          The 2008 recipient of the Foundation for
     Surgery Scholarship, Dr Chen is investigat-
     ing the pattern of Activin A release as part of
     his Master of Surgery Degree at the Monash
     Medical Centre. Dr Chen said Activin A had
     only been isolated within the past twenty years
     and that while it was originally understood
     to be primarily a reproductive hormone, new
     research suggests it may have a wider role.
          “Recent studies have shown that Activin A is
     released very early by people who have septicae-
