Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry
The Journal of Agricultural and Food Chemistry has retracted three papers by Dipak Das, the resveratrol researcher found to have committed more than 100 counts of fraud by the University of Connecticut.
Journal editor James Seiber writes:
The Journal of Agricultural and Food Chemistry, as all Journals published by the American Chemical Society, is committed to upholding the highest standards of integrity in the content of manuscripts submitted for publication. In adherence to this commitment, the following three previously published articles are being retracted:
Freshly Crushed Garlic is a Superior Cardioprotective Agent than Processed Garlic
Subhendu Mukherjee, Istvan Lekli, Shyamal Goswami, and Dipak K. Das
J. Agric. Food Chem.2009, 57 (15), 7137–7144
Does White Wine Qualify for French Paradox? Comparison of the Cardioprotective Effects of Red and White Wines and Their Constituents: Resveratrol, Tyrosol, and Hydroxytyrosol
Jocelyn I. Dudley, Istvan Lekli, Subhendu Mukherjee, Manika Das, Alberto A. A. Bertelli, and Dipak K. Das
J. Agric. Food Chem.2008, 56 (20), 9362–9373
Broccoli: A Unique Vegetable That Protects Mammalian Hearts through the Redox Cycling of the Thioredoxin Superfamily
Subhendu Mukherjee, Hiranmoy Gangopadhyay, and Dipak K. Das
J. Agric. Food Chem.2008, 56 (2), 609–617
These papers were the subject of a recently completed (January 2012) research misconduct investigation by the University of Connecticut Health Center. This investigation determined that images appearing in these papers contained instances of data fabrication and/or data falsification. This is a violation of the ethical standards of the American Chemical Society (Ethical Guidelines to Publication of Chemical Research, 2011; Section B.1) and Journal of Agricultural and Food Chemistry policy.
This action is effective immediately.
The papers have been cited 5, 37, and 34 times, respectively, according to Thomson Scientific’s Web of Knowledge. The white vs. red wine study was the subject of a UConn press release.
The editor’s note is freely available, while the individual notices are behind paywalls. And as in other American Chemical Society journals, the original abstracts list an “Addition/Correction” rather than a retraction. The journal has made the original papers freely available, as this notice for one of the retractions says:
This paper was withdrawn at the request of the Editor-in-Chief due to violations of the Ethical Guidelines to Publication of Chemical Research of the American Chemical Society. A Special Review Board formed by the University of Connecticut Health Center investigated allegations of research misconduct brought to its attention by the U.S. Office of Research Integrity (Case DIO 3995) and found three instances of data fabrication in Figures 6, 7, and 8 of the above paper. The Special Review Board voted unanimously that this represented research misconduct as defined in the University of Connecticut Health Center’s policy. The original paper was published ASAP on July 17, 2009, and withdrawn on March 14, 2012. The PDF content of the original paper is attached to the Addition and Correction as Supporting Information.
