When citing a journal article, use:
Example:
1. Villalobos AR, Parmelee JT, Renfro JL. Choline uptake across the ventricular membrane of neonate rat choroid plexus. Am J Physiol Cell Physiol 276: C1288-C1296, 1999.
Unpublished/Prepublished Papers:
Papers may appear in online format before being formally published in print. To cite a prepublished paper, use a digital object identifier, or DOI, in your citation, as well as the date of initial access. Once a paper is published in print the citation can be modified to include publisher information, but the DOI and date of initial access are retained.
