In the article listed above, there are errors in Figures 3, 4, and 5, which show the effects of quercetin and apigenin in CD38 activity in vitro and in cells. The labels on the figures should read [Apigenin] and [Quercetin] and not Log [Apigenin] and Log [Quercetin] since the actual concentration is shown in the axis, and the scale already is log. These changes have no impact on the results or the conclusions of the study.

The online version reflects these changes.
