Two patch-clamping retractions in PNAS and the JCI after first author admits image manipulation

jci1212A group of cardiology researchers formerly of the University of Cologne has retracted two papers, after investigations into allegations of misconduct led to an admission of guilt by one of the lab’s junior members.

Here’s the first retraction, for “Connexin 43 acts as a cytoprotective mediator of signal transduction by stimulating mitochondrial KATP channels in mouse cardiomyocytes,” published last week in the Journal of Clinical Investigation: Continue reading Two patch-clamping retractions in PNAS and the JCI after first author admits image manipulation

Going Dutch: Stapel inquiry eyes credulous colleagues, institution, prompts national soul search

Dutch investigators have released their final report into the case of Diederik Stapel, the social scientist and erstwhile faculty member at Tilburg University who fabricated data in 55 articles and book chapters. So far, 31 of Stapel’s published papers have been retracted — three others have expressions of concern — although more might follow.

In addition, 10 dissertations by students Stapel supervised were found to contain fraudulent data, although those students were cleared of any wrongdoing in the inquiry.

The report — and we’re going by rough translations here — found that Stapel’s colleagues and administrators seemed to accept his results at face value. Meanwhile, his high profile at Tilburg insulated him against initial rumblings about problems with his data. As the Dutch paper NRC Handelsblad reported: Continue reading Going Dutch: Stapel inquiry eyes credulous colleagues, institution, prompts national soul search

Lemus, Stapel each rack up another retraction

The retraction counts keep mounting for two Retraction Watch frequent flyers.

First, Diederik Stapel’s 26th retraction, according to our count. Psychologist Stapel admitted to making up data in dozens of studies, and is also facing a criminal inquiry for misuse of funds.

Here’s the notice: Continue reading Lemus, Stapel each rack up another retraction

ORI investigating University of Florida ob-gyn researcher accused of misconduct

A prominent researcher at the University of Florida is under federal investigation for research misconduct and has lost at least one paper as a result of the fraud.

The researcher, Nasser Chegini, was a professor of obstetrics and gynecology at the U of Florida until about six months ago, when he retired, according to the chair’s office. Nasser has received at least $4 million in federal grant funding, according to the university.

The retracted paper, “MicroRNA 21: response to hormonal therapies and regulatory function in leiomyoma, transformed leiomyoma and leiomyosarcoma cells,” was published in 2010 by Molecular Human Reproduction. The authors were Qun Pan and Xiaoping Luo and Chegini.

Final report on cardiology researcher Poldermans confirms claims of misconduct

Erasmus Medical Center in the Netherlands has released the final report on Don Poldermans, finding that the institution’s once-star cardiology researcher committed misconduct.

As Larry Husten of CardioBrief reports, Erasmus MC’s investigation included that Poldermans — perhaps best known for his work on beta-blockers — has admitted to acts of misconduct but not to fraud.

That’s not merely a distinction without a difference. Continue reading Final report on cardiology researcher Poldermans confirms claims of misconduct

JAMA’s first-ever Expression of Concern appears for hip protector study

JAMA has issued its first-ever Expression of Concern over a 2007 study of hip protectors in the elderly that came under scrutiny from Federal regulators.

As the Boston Globe was first to report yesterday, the journal’s editor and executive deputy editor wrote in a notice published online: Continue reading JAMA’s first-ever Expression of Concern appears for hip protector study

Retraction appears for paper by social psychologist Dirk Smeesters

A paper by Dirk Smeesters — the former Erasmus University social psychology professor investigated for serious irregularities in his work — has been retracted.

The study, “Visual perspective influences the use of metacognitive information in temporal comparisons,” appeared in the Journal of Personality and Social Psychology earlier this year. Here’s the notice, which doesn’t quite say “fraud”: Continue reading Retraction appears for paper by social psychologist Dirk Smeesters

University clears leading dermatology lab head of misconduct as authors issue two corrections

Michael Hertl, a leading dermatology researcher at Philipps-University Marburg, has been cleared of any wrongdoing in a case that spawned a retraction last year and two just-published retractions.

Felicitas Riedel, a legal officer for the university, tells Retraction Watch that the

…Committee for Scientific Misconduct of the Philipps-University Marburg closed the matter and submitted its results to the President of the University who in the meantime after examination consented with it.

The findings? Continue reading University clears leading dermatology lab head of misconduct as authors issue two corrections

Senior author “fully confident” in paper that cites retracted Cell study and shares first author

Last week, we reported on an investigation at Glasgow’s Beatson Institute for Cancer Research into the circumstances of a retraction in Cell. That retraction wasn’t signed by the paper’s first author, Lynne Marshall, who had since moved on to another institution. (We have yet to hear back from Marshall about why she didn’t sign.)

As a commenter on that post pointed out, Marshall was the first author on an EMBO Journal paper that cited the now-retracted Cell paper several times. So we wanted to find out if there were any questions about the EMBO Journal paper, “Nutrient/TOR-dependent regulation of RNA polymerase III controls tissue and organismal growth in Drosophila,” published in February of this year. Savraj Grewal, Marshall’s PI at the University of Calgary until her postdoc ended earlier this summer, tells Retraction Watch: Continue reading Senior author “fully confident” in paper that cites retracted Cell study and shares first author

Fifth Alirio Melendez retraction offers clues about University of Glasgow misconduct findings

A new retraction — his fifth — in the Journal of Immunology for Alirio Melendez, formerly of the National University of Singapore, the University of Glasgow, and the University of Liverpool, sheds some light on the results of an investigation by one of the universities.

Last month, a Glasgow spokesperson told Nature that the university’s investigation had been completed in October 2011, but that it did not comment on individual cases. A spokesperson, according to the Times Higher Education:

…would say only that there was “no evidence that our current staff contributed, falsified or duplicated data to any publications co-authored with (Professor) Melendez”. He also confirmed that relevant journals would be contacted where retractions or corrections were deemed necessary.

The notice for one such necessary retraction, in the September 15 issue of the Journal of Immunology, gives a few details: Continue reading Fifth Alirio Melendez retraction offers clues about University of Glasgow misconduct findings
