On the last post I sent in today, I messed up my references for
the first section. The first reference (3) should be: Salem N et al.
Arachidonic and docosahexaenoid acids are biosynthesized from their
18-carbon precursors in human infants. Proc Natl Acad Sci 1996;93:49-54.
The second (3) in the text should actually be (4) and the reference (3)
in the list of references should be labeled (4).
