Anil Jaiswal

When journals learn papers are problematic, how long does it take them to act?

We recently had a chance to find out as part of our continuing coverage of the case of Anil Jaiswal at the University of Maryland, who’s retracted 15 papers (including two new ones we recently identified), and has transitioned out of cancer research. Here’s what happened.

As part of a public records request related to the investigation, we received letters that the University of Maryland sent to 11 journals regarding 26 “compromised” papers co-authored by Jaiswal, four of which had been retracted by the time of the letter. The letters were dated between August and September 2016 (and one in February) — although, in some cases, the journals told us they received the letter later. Since that date, three journals have retracted nine papers and corrected another, waiting between four and six months to take action. One journal published an editorial note of concern within approximately two months after the university letter.

And six journals have not taken any public action.

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: Read the rest of this entry »
