  IAN: I sent that moments after collating
  and stapling copies from my last NLM visit
  and did not yet notice that the new study
  is by the same authors as the first. But,
  the second is a review of a larger body
  of research than just the first study.
  This was published in "Metal Ions in
  Biological Systems," volume 34, 1997,
  Institute of Inorganic Chemistry,
  University of Basel, Switzerland.
