Another image falsification retraction for Emory heart researchers

jbc1112coverA group of authors from Emory University, has lost another paper for image manipulation, bringing their total to at least four. What makes this particularly interesting is that the main actor in the figure fakery, Lian Zuo, does not appear to have been involved this time.

Zuo, you may recall, was cited in multiple retraction notices back in 2011 after Emory investigators concluded that he appeared to have been fabricating figures. But, one of the notices, from Circulation Research, raised the possibility that someone else was implicated, too: Continue reading Another image falsification retraction for Emory heart researchers

Second retraction stemming from Cardiff investigations appears

cancer research 1113A second retraction of a paper by a Cardiff University researcher found to have committed misconduct has appeared.

In April, a Cardiff investigation found that Rossen Donev, a former researcher at the university, had manipulated images in four different papers. Donev, who was at the University of Swansea until August, according to his LinkedIn profile, and is now director of Biomed Consult Ltd., had already retracted a Journal of Immunology paper in late 2011 after a different Cardiff investigation.

The investigation cleared co-author and dean Paul Morgan of misconduct. Morgan resigned from Cardiff in August, but “he categorically denied that his decision had anything to do with the misconduct investigation,” according to Times Higher Education.

Here’s the new notice, from Cancer Research: Continue reading Second retraction stemming from Cardiff investigations appears

JBC issues correction for paper by Khachigian, who has had four others retracted

jbc1113The Journal of Biological Chemistry has a fairly gory correction — we’d call it a mega-correction — for a 2010 paper by Levon Khachigian, an Australian researcher whose studies of a new drug for skin cancer recently were halted over concerns about possible misconduct, including image manipulation. As we reported earlier this year, Khachigian has already lost four papers, including one in the JBC — which the journal simply noted had “been withdrawn by the authors.”

The new correction involves the article “c-Jun regulates shear- and injury-inducible Egr-1 expression, vein graft stenosis after autologous end-to-side transplantation in rabbits, and intimal hyperplasia in human saphenous veins,” which Khachigian wrote with Jun Ni and Alla Waldman. The paper has been cited nine times, according to Thomson Scientific’s Web of Knowledge. Here’s the notice: Continue reading JBC issues correction for paper by Khachigian, who has had four others retracted

He said, she said: Journal of Neuroscience expresses concern, but doesn’t pursue investigation

j neuroscienceThe Journal of Neuroscience‘s retraction notices often give us plenty to chew on, and a new Expression of Concern does the same.

In the notice — for a 16-year-old paper — the journal notes three cases of what certainly sounds like image manipulation, but carefully avoids calling it that: Continue reading He said, she said: Journal of Neuroscience expresses concern, but doesn’t pursue investigation

Image manipulation leads to fifth retraction for plant research group

plant scienceA plant scientist at the Colorado State University has retracted a fifth paper.

Here’s the notice for “Influence of ATP-binding cassette transporters in root exudation of phytoalexins, signals, and in disease resistance, a paper originally published in July 2012:

The Journal, Chief Editor and the Authors wish to retract the Original Research article cited above in its entirety. Based on information reported after publication, this article was found to have images that were inappropriately manipulated (Figure 1B: actin panel; Figure 6A: PR1, PR5; Figure 6B: AtATH6, AtATH10). The authors and the journal regret the errors and regret any inconvenience to the readers of Frontiers in Plant Science.

The last author of the now-retracted paper, Jorge Vivanco, has had four previous retractions, including one in Nature. He tells us: Continue reading Image manipulation leads to fifth retraction for plant research group

Retraction for stem cell scientist facing misconduct inquiry

scadcoverHere’s a retraction from Stem Cells and Development that we’re just now getting around to covering. The paper, “Non-viral reprogramming of skeletal myoblasts with valproic acid for pluripotency,” appeared in June 2012 in a preliminary online form and was written by a group at the University of Cincinnati. As the retraction notice states: Continue reading Retraction for stem cell scientist facing misconduct inquiry

“Ambiguities in the presentation of some of the data” lead to an ambiguous retraction notice

Italian cancer specialist facing criminal investigation for misconduct

A leading Neapolitan cancer researcher is under criminal investigation for fraud, the Italian press is reporting.

Although we have only rough translations of the story, it seems the researcher, Alfredo Fusco, of the National Council of Research’s Institute of Experimental Endocrinology and Oncology, has been accused of manipulating images in published studies and to strengthen the case for grants from the Italian Association for Cancer Research (AIRC).

The case covers eight papers published between 2001 and 2012, according to the media reports. We don’t know the specifics of the eight articles, nor why none appears yet to have been retracted. In our experience, the criminal inquiries usually follow the expose of scientific misconduct, not the other way around.

Fusco’s work is highly cited, with some 50 papers cited at least 100 times, according to Thomson Scientific’s Web of Knowledge.

According to the institute’s website: Continue reading Italian cancer specialist facing criminal investigation for misconduct

Aoki notches fourth retraction for image problems

jbc1013We have a fourth retraction in the Journal of Biochemistry for Naohito Aoki, a Japanese researcher and former postdoc in a German lab, whose images have been called into question but whose retraction notices were scant. In this case, however, the journal, while not exactly overbrimming with information about the article, at least gives us some sense of what’s going on.

Aoki worked in the lab of Axel Ullrich, of the Max Planck Institute of Biochemistry, and appeared on two retracted articles in the Journal of Biological Chemistry (JBC) with his mentor, along with a third with a co-author from Japan, Tsukasa Matsuda. Although those notices don’t say anything about the reason for the retractions — this was before the JBC started providing such information — Ulrich told us that Aoki had been manipulating images.
