Drunk rats paper wasted by “significant statistical errors”, among other issues

MolBiolRep_ak5Authors from Xinxiang Medical University in Weihui, China, are retracting a 2014 paper in Molecular Biology Reports because… well, because lots of things.

The researchers exposed nine rats to acute levels of alcohol then compared them to unexposed mice rats, noting differences in gene expression and molecular pathways.

But no one is toasting these findings anymore. Here are the details behind the retraction, courtesy of the notice:

Third structure slip-up for chemist in Korea yields retraction

Chem_ak3Authors of a 2010 Chemistry – A European Journal article have retracted it “due to the wrong assignment of structure” of catalysts.

The retraction is the third, by our count, for corresponding author Doo Ok Jang, a chemist at Yonsei University in Wonju. Jang authored one of the previously retracted papers with Sung Jun Kim and the other with Sang Yoon Kim. Both papers were also sunk by misassigned structures.

The current study, “Enantioselective Radical Addition to Ketimines: A Synthetic Route Towards α,α-Disubstituted α-Amino Acids,” is authored by all three chemists. Here’s the retraction notice:

So you want to be a whistleblower? Part II

John R. Thomas

This is the second article in a series by John R. Thomas, Jr., a lawyer at Gentry Locke [Editor’s note, 3/26/19: He has since moved to Haley, Hafemann, Magee and Thomas] who represents whistleblowers in a variety of False Claims Act cases. In this installment, he writes about how whistleblowers can tell if they have a viable FCA case.

In my first article, I briefly outlined the role that the False Claims Act (FCA) can play in promoting scientific integrity and safeguarding public grant funding. This article will answer a more substantive and practical question that a potential whistleblower must consider: What constitutes a viable FCA case?

Authors retract leptin paper due to “fabricated data”

CellPress_ak2The authors of a study on the effects of the hormone leptin on the liver have retracted it from Cell Metabolism, almost four months after the Office of Research Integrity (ORI) determined it contained faked data, courtesy of its first author.

However, the authors say that the paper’s conclusions remain valid, and are supported by new experiments and additional research by outside groups.

Here’s more from the retraction notice: Continue reading Authors retract leptin paper due to “fabricated data”

Widely covered editorial extolling importance of diet over exercise “temporarily removed”

The British Journal of Sports Medicine has “temporarily removed” an editorial arguing that physical activity alone will not cure the obesity epidemic, following an expression of concern.

In its place stands the following message:

This paper has been temporarily removed following an expression of concern.

First author Assem Malhotra, based at the Department of Cardiology, Frimley Park Hospital and Consultant Clinical Associate to the Academy of Medical Royal Colleges, told us the paper was pulled due to a “technical issue,” and an “official explanation” would be forthcoming.

Indeed, just this morning, we received a statement from Fiona Godlee, editor of the British Medical Journal, which publishes the British Journal of Sports Medicine:

“Unreliable” data suffocates third paper for Duke pulmonary team

ajrcmbOnce again, a team of Duke University scientists has retracted a paper, this time due to “unreliable” figure data.

With co-authors at the U.S. Environmental Protection Agency, the Duke team has withdrawn a paper from the American Journal of Respiratory Cell and Molecular Biology after concern about data in three figures led them to repeat one of their main experiments. They subsequently found “no evidence” supporting their previous conclusion.

By our count, it is the third retraction from a team that includes William Foster, a pulmonary researcher at the Duke Medical Center. The Duke team retracted a paper in 2013 on a related topic—the effect of early life ozone exposure on airways—from the Journal of Applied Physiology when it was discovered that, familiarly, data in a figure were “unreliable”. Recently, they also retracted a PNAS paper on asthma treatment earlier this month, due to missing primary data and mismatched data from two sources.

Malpractice case against Duke, Anil Potti settled

pottiA lawsuit filed in October 2011 against Duke University and Anil Potti, who has retracted 11 papers and corrected a number of others amidst investigation into his work, has been settled, Retraction Watch has learned.

Potti resigned from Duke in 2010 following questions about his work, and revelations that he had lied on grant applications about being awarded a Rhodes Scholarship. He now works at a cancer center in North Dakota.

The lawsuit was filed by subjects in clinical trials based on Potti’s work. Plaintiff’s attorney Thomas W. Henson, who confirmed the settlement, tells Retraction Watch: Continue reading Malpractice case against Duke, Anil Potti settled
