Das, via UConn

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: Continue reading Retraction count for resveratrol researcher Dipak Das rises to 12

The retraction count for Dipak Das, the resveratrol researcher whom the University of Connecticut found to have committed 145 counts of fabrication and falsification of data, has risen to eight with withdrawals by Free Radical Biology & Medicine and Free Radical Research.

The two Free Radical Biology & Medicine retractions, for “Expression of the longevity proteins by both red and white wines and their cardioprotective components, resveratrol, tyrosol, and hydroxytyrosol” (cited 38 times, according to Thomson Scientific’s Web of Knowledge) and “Redox regulation of resveratrol-mediated switching of death signal into survival signal” (cited 32 times), are carefully detailed and read the same way: Continue reading Three more retractions for resveratrol researcher Dipak Das, in free radical journals

Resveratrol researcher Dipak Das: My lab’s work was “99% correct”

Das, via UConn

Dipak Das, the UConn red wine researcher charged by his institution with rampant misconduct that will likely lead to dozens of retractions, is evidently a 99%-er — when it comes to accuracy, that is.

According to a statement purportedly from his lawyer refuting those charges, Das claims, among other things, that the output from his lab was nearly perfect. He also has a lot to say about a 60,000-page report that the statement says he may not have actually downloaded.

We might note a lot more things about the letter, which we received from Bill Sardi, president of Longevinex, a resveratrol company which has worked with Das. Sardi has been sending Das defenses since the story broke; we posted some of them and Derek Lowe has posted parts of another. But here’s the letter, in its entirety: Continue reading Resveratrol researcher Dipak Das: My lab’s work was “99% correct”

So how peripheral was Dipak Das’ resveratrol work, really?

In the wake of the massive allegations of fraud by resveratrol researcher Dipak Das, other researchers in the field are clearly trying to distance themselves from the University of Connecticut scientist. Nir Barzilai told us yesterday, for example, that despite Das seemingly’ impressive publication record, “Rome was not built on Dr. Das.”

Harvard’s David Sinclair went further, telling The New York Times that he didn’t know who Das was: Continue reading So how peripheral was Dipak Das’ resveratrol work, really?

Resveratrol fraud case update: Dipak Das loses editor’s chair, lawyer issues statement refuting all charges

Das, via UConn

Many Retraction Watch readers will now be familiar with the case of Dipak Das, the resveratrol researcher about whom the University of Connecticut issued a voluminous report yesterday — summary here — detailing 145 counts of data fabrication and falsification. This has been a fast-moving story, so we wanted to highlight a number of updates to our original post, and offer a few more.

First, we have confirmed with publisher Mary Ann Liebert this morning that Das has been relieved of his duties as co-editor in chief of Antioxidants & Redox Signaling. He had shared that post with Chandan Sen, and his name as been removed from the masthead of that journal. Here’s a statement from the publisher: Continue reading Resveratrol fraud case update: Dipak Das loses editor’s chair, lawyer issues statement refuting all charges

UConn resveratrol researcher Dipak Das fingered in sweeping misconduct case

Das, via UConn

The University of Connecticut, in what clearly seems like an attempt to get ahead of damaging news, has announced an “extensive” investigation into research misconduct involving one of its scientists, Dipak K. Das.

According to a press release, the university has notified 11 journals that published Das’ work about the alleged fraud. One area of interest for Das, a government-funded professor of surgery and director of the Cardiovascular Research Center, has been resveratrol, a substance in red wine that has allegedly been linked to improved cardiac health.

The university touted some of his early efforts in this field.
