Follow this timeline, if you would:
- August 14, 2013: Former UConn researcher Dipak Das, who was found to have committed misconduct, submits a paper to Oxidative Medicine and Cellular Longevity.
- September 19, 2013: Das dies.
- October 17, 2013: Das submits revisions to his paper in Oxidative Medicine and Cellular Longevity.
- October 18, 2013: Paper accepted.
- January 12, 2014: Paper published.
That would appear to be what the timeline on the paper — which lists Das as corresponding author, along with a Gmail address — says:
Here’s the notice, for “Dynamic Action of Carotenoids in Cardioprotection and Maintenance of Cardiac Health,” from Molecules:
We have a few follow-ups from stories we’ve recently covered:
Terry Elton case initially chalked up to “disorganization,” not misconduct
Ohio State University (OSU), which along with the Office of Research Integrity (ORI) recently sanctioned a pharmacy professor for image manipulation, “failed at first to recognize his deception,” according to an investigation by The Columbus Dispatch based on university documents.
The piece, which quotes Ivan, reveals that OSU needed some prompting from the ORI before it concluded that Terry Elton was guilty of misconduct, and not just unintentional errors that he at one point blamed on a research technician who lost her job in October 2011: Read the rest of this entry »
A group of smoking researchers — no, not scientists who are on fire; scientists who study the effects of tobacco smoke — has retracted a 2009 article after deciding that they were no longer “satisfied with the quality of the data.”
The paper, “Cigarette Smoke–induced Oxidative/Nitrosative Stress Impairs VEGF- and Fluid Shear Stress–Mediated Signaling in Endothelial Cells,” came from the lab of Irfan Rahman, a lung disease expert at the University of Rochester. It appeared online in 2009 in Antioxidants & Redox Signaling, which will be familiar to readers watching the case of Dipak Das.
Odd: Retractions 18 and 19 for Dipak Das, and a new paper in the same journal, as if nothing were amiss
Dipak Das, the resveratrol researcher found guilty of more than 100 counts of misconduct by the University of Connecticut, has two more retractions for his resume. But that’s not the most interesting part of this post, so keep reading after the notices.
We have four more retractions by Dipak Das, the disgraced UConn researcher found by the university to have committed 145 counts of misconduct. All appear in the Journal of Molecular and Cellular Cardiology (we left the journal off when we initially posted, as commenters noted):
“Redox regulation of angiotensin II preconditioning of the myocardium requires MAP kinase signaling,” cited 28 times, according to Thomson Scientific’s Web of Knowledge:

Today’s Retraction Watch, to paraphrase Sesame Street, is brought to you by the number 13.
Earlier, we reported on several retractions from Diederik Stapel that bring his total to that number, and now we’ve learned about number 13 for Dipak Das. Das is of course the UConn researcher who was found to have committed 145 counts of misconduct in his studies of the red wine compound resveratrol and other subjects.
Here’s the notice, from The Journal of Nutritional Biochemistry, for “Resveratrol, a unique phytoalexin present in red wine, delivers either survival signal or death signal to the ischemic myocardium depending on dose:” Read the rest of this entry »
Resveratrol researcher Das in video: Yes, I manipulated images, but only because the journals asked me to
Dipak Das, who until earlier this year ran a high-profile cardiovascular research center at the University of Connecticut, has recorded a slick looking video defense against allegations that he cooked data and manipulated images in scores of published studies, 12 of which have been retracted to date.
Das, who was hit with a 60,000 pages of allegations stemming from a three-year investigation by the university, spends the bulk of the documentary-style interview — which is available on YouTube — talking about the wonders of resveretrol. But he gets into the misconduct charges at about the 15-minute mark.
Dipak Das, the UConn researcher whom the university earlier ths year found to have fabricated or falsified data more than 100 times, has four more retractions to his name.
The notices appear in the June 1, 2012 issue of the American Journal of Physiology: Heart and Circulatory Physiology, and suggest that Das was not all that cooperative: Read the rest of this entry »
