Former NIH postdoc doctored data

ori-logoA genetics researcher included falsified data in two published papers, according to a report by the U.S. Office of Research Integrity (ORI) released today.

At the time of the misconduct, Andrew Cullinane was a postdoctoral fellow in the Medical Genetics Branch at the National Human Genome Research Institute (NHGRI). According to his LinkedIn page, he is now an assistant professor at Howard University in Washington D.C. The university’s College of Medicine lists him as an assistant professor in the Basic Sciences/Anatomy department.

As today’s notice in the Federal Register reports, Cullinane Continue reading Former NIH postdoc doctored data

Former professor shoots dean who fired him for misconduct

MountSinai_IcahnSchool_LogoA former assistant professor at the Mount Sinai School of Medicine in New York fired a shotgun yesterday at two men– including the school’s dean, who had fired him six years ago.

The New York Times reports that Hengjun Chao was taken into custody on charges of attempted murder, after his shots hit Mount Sinai dean Dennis Charney and another man outside of a suburban New York deli. Both men were treated at a local hospital for non-life-threatening injuries.

Chao was fired from Mount Sinai in 2010 after an investigating committee found that he Continue reading Former professor shoots dean who fired him for misconduct

A prominent researcher in Scotland has been suspended amidst a misconduct investigation at the University of Dundee.

According to The Scotsman, the allegations against Robert Ryan center around falsifying data and duplicating figures in his work about molecular bacteriology.

U Colorado’s former “golden boy” up to 7 retractions

University of Colorado DenverA former graduate student at the University of Colorado Denver has gained three retractions and two expressions of concern (EOC), following an institutional probe into his work. 

Last year, we reported on an investigation by the University of Colorado Denver into the research of Rajendra Kadam, which recommended retracting 10 papers. The report also flagged eight additional papers co-authored by Kadam whose data could not be validated, raising “concerns as to the scientific validity and integrity” of the material. A few months later, we reported on some of the notices — four retractions and an EOC — that had begun to appear for Kadam’s manuscripts.

We’ve since discovered more notices, bringing his total to seven retractions and three EOCs. 

Kadam was once a prominent member in the lab of Uday Kompella, and often referred to by colleagues as the “golden boy,” according to the institution’s report. In 2012, he won a graduate student symposium award from the American Association of Pharmaceutical Scientists.

7th retraction for Ohio researcher who manipulated dozens of figures

A pharmacology researcher at Ohio State University has added his seventh retraction, four years after a finding of misconduct by the U.S. Office of Integrity (ORI).

An analysis of the work of Terry Elton determined that he had

falsified and/or fabricated Western blots in eighteen (18) figures and in six (6) published papers.

 In 2012, the ORI finding, which resulted in a three-year funding ban (that is now complete), recommended that Elton retract all six papers, one of which had already been retracted at the time of the report. 

Four years later, the last of the six papers flagged by the ORI has finally been retracted by Molecular and Cellular Endocrinology.

Here’s the retraction notice: Continue reading 7th retraction for Ohio researcher who manipulated dozens of figures

A retraction cluster? Two papers retracted for overlap with other retractions

molecular biology reportA cluster of papers by different authors has been retracted for sharing text, even though some papers were submitted at the same time.

How is that possible? A spokesperson for Springer told us that they have reason to believe a third-party company may have helped prepare the papers for publication, and in the process might have spread the material around to multiple manuscripts.

The details of the cluster are a bit perplexing, so bear with us. Two of the papers — that were published only months apart — have already been retracted, as we reported in April. Now, two other papers have been retracted from Molecular Biology Reports — and both notices cite the previously retracted papers. The new notices also say that there’s reason to believe that the peer-review process was compromised.

All papers conclude that a certain polymorphism could signal a risk for coronary artery disease among Chinese people.

We’ll start with the retraction notice for “Fibroblast growth factor receptor 4 polymorphisms and coronary artery disease: a case control study,” which cites the two papers that were retracted previously:

Does dose matter? Tumor killer paper thought so, now must retract

Molecular Medicine ReportsAfter questions from a reader, researchers took a second look at their data about the effects of a vitamin A metabolite on tumor cells, and realized their key finding was inaccurate.

They’re now retracting the paper, from Molecular Medicine Reports, because it originally reported that higher concentrations of retinoic acid (RA) were more effective in curbing the proliferation of brain tumor cells. But it seems that the RA dose made less of a difference than they originally believed, according to the retraction notice:

Five more retractions for researcher who sued PubPeer commenters brings tally to 18

Fazlul Sarkar
Fazlul Sarkar

A cancer researcher who tried to sue PubPeer commenters for criticizing his work has earned five more retractions, bringing his total to 18. 

All of the new retractions for Fazlul Sarkar, formerly based at Wayne State University in Michigan, appear in the International Journal of Cancer. All cite an institutional investigation, and relate to issues with images.

With 18 retractions, Sarkar has now earned a spot on our leaderboard.

We first encountered Sarkar when he subpoenaed PubPeer to reveal the names of anonymous commenters that potentially cost him a job at the University of Mississippi. Earlier this month, a Wayne State spokesperson confirmed to us that Sarkar has now retired from the university. (To get up to speed, check out our timeline on the major events in this case.)

Here’s the first of the retraction notices, issued today: Continue reading Five more retractions for researcher who sued PubPeer commenters brings tally to 18

Journal blacklists authors for plagiarizing case report about hypersexuality in dementia

Advances in Human BiologyA biology journal has blacklisted authors from publishing their work after finding their case report about a dementia patient with hypersexuality was plagiarized from a previously published report.

The retraction notice, issued by Advances in Human Biology (AIHB) in June, recognizes the case as “scientific misconduct.” The journal launched an investigation after the plagiarism was flagged by the author of the original report, the editor-in-chief of the journal told us. Eventually, the journal retracted the report — and removed it entirely from their website.

Additionally, the journal posted this notice on their site, blacklisting the authors from publishing in AIHB again: Continue reading Journal blacklists authors for plagiarizing case report about hypersexuality in dementia

Author loses five papers, most for “compromised” peer review

PLOS OnePLOS ONE has retracted three papers after the first author admitted to submitting the manuscripts without co-authors’ consent, and an investigation suggested that two out of the three papers had received faked reviews.

Last August, the same author — Lishan Wang of the Shanghai Jiao Tong University — lost two more papers (one in Tumor Biology and the other in Gene), also after the peer review process was found to be compromised. All five papers — which share other authors in common — were originally published in 2013, and four list Wang as the first author. The retractions follow an investigation by Shanghai Jiao Tong University.

Here’s the retraction notice for two of the PLOS ONE papers, issued on July 26: Continue reading Author loses five papers, most for “compromised” peer review
