Three more retractions for resveratrol researcher Dipak Das, in free radical journals

Das, via UConn

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

Watch and learn, science journals: “This American Life” retracts Mike Daisey segment on Apple in China

“This American Life,” the popular radio show hosted by Ira Glass, is retracting an episode in which monologist Mike Daisey claimed to have described conditions in a Chinese factory that makes electronic devices, including Apple products. According to a note about this week’s episode:

Regrettably, we have discovered that one of our most popular episodes was partially fabricated. This week, we devote the entire hour to detailing the errors in “Mr. Daisey Goes to the Apple Factory,” Mike Daisey’s story about visiting Foxconn, an Apple supplier factory in China. Rob Schmitz, a reporter for Marketplace, raises doubts on much of Daisey’s story.

Ira also talks with Mike Daisey about why he misled This American Life during the fact-checking process. And we end the show separating fact from fiction, when it comes to Apple’s manufacturing practices in China.

A This American Life press release spells out why the show retracted the segment, and it isn’t pretty. The doubts started with Rob Schmitz, who interviewed Daisey’s Chinese interpreter, Li Guifen. (She  goes by Cathy Lee professionally with Westerners, according to the release.) A lot of what Daisey had attributed to Lee was false, she said. And that came on top of the fact that Daisey had told This American Life fact-checkers that Lee’s name was Anna, and that he didn’t have a way to reach her anymore. Glass is quoted in the press release: Continue reading Watch and learn, science journals: “This American Life” retracts Mike Daisey segment on Apple in China

A non-unanimous retraction in PNAS after authors are “unable to reproduce the data”

A group of authors has retracted a 2009 paper in the Proceedings of the National Academy of Sciences (PNAS) after subsequent experiments suggested their original results weren’t holding up.

According to the notice for the paper, which has been cited 8 times, according to Thomson Scientific’s Web of Knowledge: Continue reading A non-unanimous retraction in PNAS after authors are “unable to reproduce the data”

Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry

Journal yanks anemia paper over duplicate data

Blood Cells, Molecules, and Diseases (that’s one title) has retracted a 2011 paper, “Comparative proteomics reveals deficiency of NHE-1 (Slc9a1) in RBCs from the beta-adducin knockout mouse model of hemolytic anemia,” after learning from a reader that the data it contained were previously published by a competing publication.

As the notice explains: Continue reading Journal yanks anemia paper over duplicate data

Another withdrawal by MD Anderson’s Aggarwal, again for unclear reasons

Bharat B. Aggarwal, the MD Anderson researcher under investigation at his institution over concerns of image manipulation, has withdrawn a second paper, although you’d never know why from the statement.

The notice for the article, “Evidence for the critical roles of NF-κB p65 and specificity proteins in the apoptosis-inducing activity of proteasome inhibitors in leukemia cells,” is pretty minimal: Continue reading Another withdrawal by MD Anderson’s Aggarwal, again for unclear reasons

On second thought: Transplant paper retracted for researcher error

When a group from Saint Louis University published a case report in Pediatric Transplantation on a baby with an unusual infection after kidney transplant surgery, they thought they’d stumbled on a first. At the time they wrote:

[Acalculous candidal cholecystitis] caused by Candida is an uncommon entity usually seen in the critically ill. Here, we present the case of an 18-month-old renal transplant patient who developed candidal AAC during the post-operative period. Previous articles have addressed acalculous cholecystitis secondary to a variety of causes, or addressed a wide variety of Candida infections in the biliary tract, but this is the first discussion of cholecystitis caused by Candida without confounding factors such as biliary calculi or multiple pathogens. After the discussion of our patient’s case, we also reviewed the English-language literature regarding candidal AAC and discussed diagnosis, treatment, and mortality.

A year later, however, the group is walking back their article. A retraction notice in the journal states that: Continue reading On second thought: Transplant paper retracted for researcher error

Two more retractions in respiratory journal as University of Louisville completes investigation

Last July, we reported on four retractions by a group of researchers at the University of Louisville, and we noted that the scientists’ work was under investigation. That investigation has apparently concluded, according to a retraction notice in the American Journal of Respiratory Cell and Molecular Biology for two of their papers: Continue reading Two more retractions in respiratory journal as University of Louisville completes investigation

JAMA awaiting final OHRP decision on Harvard-led paper whose authors didn’t fully disclose risks to elderly

Earlier this month, the U.S. Office for Human Research Protections (OHRP) told a group of researchers led by a Harvard Medical School professor that they hadn’t been forthcoming enough about the risks elderly subjects faced in their trial.

As the Boston Globe reported: Continue reading JAMA awaiting final OHRP decision on Harvard-led paper whose authors didn’t fully disclose risks to elderly
