Effects of alpha-linolenic acid vs. docosahexaenoic acid supply on the distribution of fatty acids among the rat cardiac subcellular membranes after a short- or long-term dietary exposure

Correction

A mistake has been noted in our recently published (25 March 2009) article [1]. This error appeared in the material and methods section, and concerns the content of Table 1.

An overlapping of the lines has occurred in the fatty acid profile section of the Table, due to an unfortunate insertion of the 22:2 n-6, a fatty acid that has nothing to do there. This returns any impossible understanding, particularly of the DHA supply and so intake. Table 1 has therefore been replaced here with a version that is both correct and also readable.
