France tries husband-wife team for research misconduct in plagiarism case

Mr Sixou
Michel Sixou

We’re always glad to have guest posts, and here’s one from François-Xavier Coudert, reporting from France.

As we reported the other day, a Nature editorial suggested that police involvement might be an appropriate response to research misconduct. The French seem to agree, based on reports in the media there, as Coudert writes:

A husband-wife team of French odontology researchers at l’université Paul-Sabatier in Toulouse have been on trial in that country for research misconduct. Christine Marchal-Sixou, an associate professor, faces a charge of plagiarism, and Michel Sixou, full professor and dean of the faculty of dental medicine until September, has been charged with complicity.

Nature Medicine retracts MS paper with ghost data by former GSK researcher

naturemed1213Nearly six months after first expressing concern about the validity of a 2010 paper on multiple sclerosis, Nature Medicine has retracted the article for containing “erroneous” data — which in this case don’t seem to have existed, making them more fabricated than wrong.

The paper, “Crucial role of interleukin-7 in T helper type 17 survival and expansion in autoimmune disease,” came from a group led by Jingwu Zhang, who at the time ran GlaxoSmithKline’s Research and Development Center in Shanghai.

In June, the journal issued an expression of concern about the article after readers discovered problems with the data, as reported by Nature Medicine’s blog.

Columbia University misconduct retraction highlights what’s wrong with the retraction process

jcacoverThe Journal of Clinical Anesthesia has a retraction of a 2006 paper by a group from Columbia University that, to our minds, is the poster child for how not to handle such things.

The article, “Dexmedetomidine infusion is associated with enhanced renal function after thoracic surgery,” was written by Robert J. Frumento, Helene G. Logginidou, Staffan Wahlander, Gebhard Wagener, Hugh R. Playford and Robert N. Sladen, who now is chief of critical care at the institution. The paper has been cited 30 times, according to Thomson Scientific’s Web of Knowledge.

Why do we bother to name all the authors? Here’s why: According to the retraction notice, one of them — but don’t ask which — is guilty of research misconduct: Continue reading Columbia University misconduct retraction highlights what’s wrong with the retraction process

A Danish researcher has responded to a draft report of the Danish Committees on Scientific Dishonesty (DCSD) that found she had acted in a “scientifically dishonest” and “grossly negligent” manner.

Bente Klarlund Pedersen, a University of Copenhagen researcher, has published with Milena Penkowa, four of whose papers have been retracted following investigations. In the press, she argued that while she had made mistakes, she had not committed misconduct.

The 57-page letter from Klarlund Pedersen’s attorney to the DCSD responds in detail to the critique of her work, including twelve papers. This passage from the summary gathers the arguments together: Continue reading Regrettable, but not scientifically dishonest: Klarlund Pedersen responds to Danish committee

An Australian university has put a hold on trials of an experimental drug for skin cancer whose main developer has been dogged by charges of research misconduct for several years.

The Australian Broadcasting Corporation is reporting that the University of New South Wales has suspended trials of the drug, DZ13, while it investigates the work of Levon Khachigian, who is leading the studies.

According to the news organization, Khachigian and his group were cleared by the school in two prior inquiries. However, additional accusations of misconduct — specifically involving image manipulation and misuse — prompted a third investigation.

We’ve found four retractions of Khachigian’s studies, from the Journal of Biological Chemistry and Biochemical and Biophysical Research Communications, between 2009 and 2010 (before the launch of Retraction Watch).

They are: Continue reading Aussie university halts trials of skin cancer drug whose developer has four retractions

University of Utah finds former faculty member guilty of misconduct because of “reckless disregard”

utahSince last May, we’ve been reporting on a case at the University of Utah involving two retractions and two corrections. When the story first broke, the lab blamed a former worker for inappropriately removing data from the premises, and the university has been investigating. Last month, we reported that Ivana De Domenico, the junior faculty member who was first author on those papers, had left the university, and that senior author Jerry Kaplan had retired.

But the problems went beyond the four papers we reported on, as the Salt Lake Tribune reported on Friday. In a 9-page report provided to the Tribune, the panel overseeing the investigation details its examination of 11 papers. This is the first of six findings: Continue reading University of Utah finds former faculty member guilty of misconduct because of “reckless disregard”
