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.
