Several journals have retracted or corrected papers from a group at State University of Maringá in Brazil over what one chemistry journal calls “fraudulent use” of figures previously published by the authors.
Química Nova, which is retracting a 2013 paper, issued a notice that taps an additional eight articles with Angelica Lazarin as the corresponding author that reused figures. Specifically, the papers included images “where same trace on the figure was assigned to different conditions and/or compounds.”
A number of the papers mentioned in the Química Nova notice were co-authored by Claudio Airoldi, whose group retracted 11 papers in 2011 following concerns over fraudulent nuclear magnetic resonance images.
Danish judges have overruled scientists in that nation, concluding that a panel of experts erred in finding that physiologist Bente Klarlund Pedersen, of the University of Copenhagen, was guilty of misconduct.
Last September, Pedersen announced that she would fight the ruling of the Danish Committees on Scientific Dishonesty (DCSD, Danish acronym UVVU), which had said she had committed misconduct in four of 12 articles it had examined.
The State University of Campinas University of Campinas and the American Diabetes Association disagree strongly over how to handle disputed images from faculty member Mario Saad, who is suing the ADA to prevent retraction of his papers.
While the State University of Campinas University of Campinas (Unicamp) acknowledges that 2 of Saad’s papers contain “mistakes”, it concluded there was “not an intention in the actions of the authors,” and the mistakes did not have a negative impact on the scientific community. Ultimately: “the studies published have their own strength, are healthy and were not artificially strengthened by the incorrect images.”
In response, however, Saad’s lawsuit says the ADA asked the school to reinvestigate the articles, and refused to accept any papers from Unicamp faculty in any ADA journals until the issues are resolved.
The ADA has issued four expressions of concern in Saad’s research published in its flagship journal, Diabetes. Saad’s lawsuit aims to prevent the journal from retracting those papers, and asks for monetary compensation.
Retraction Watch has obtained a report of the investigation by Unicamp and Saad’s lawsuit. You can read the full lawsuit here, and the investigation report here.
Tulane researchers Tong Wu and Chang Han, who have been anonymously accused of figure duplication in the past, have now finally lost a paper for that reason.
The frequent plagiarism tipster Juuichi Jigen (a pseudonym) set up a blog in 2012 alleging that the pair inappropriately reused images in six other papers, though none of those have been retracted. The recent notice, issued at the end of January by the Journal of Cellular Biochemistry, states that the figure duplication was confirmed by the University of Pittsburgh’s Office of Research Integrity. Han, the first author, was at UPitt when the paper was published in 2008, though she moved to join Wu at Tulane in 2009.
As reported in the Boston Business Journal, Saad’s lawsuit claims that his institution, the State University of Campinas, investigated two articles at the journal’s behest. The American Diabetes Association was unhappy with the results, and asked the school to reopen the investigation, including two additional papers.
Saad is suing to prevent the journal from retracting the papers, in addition to monetary compensation.
The hits keep coming for University of Maryland researcher Anil Jaiswal.
The latest retraction for the cell biologist is in Cancer Research, for a 2007 paper about ways in which the cell tries to protect the tumor suppressor p53. Like the first Jaiswal retraction we covered, the latest notice specifically taps figure duplication as the cause of death, “as a result of an error.” The other two retractions gave no explanation for the withdrawal.
The authors of a 2007 PNAS paper that provided molecular details for how calorie restriction may act on Sir2 enzymes to extend life are now retracting their research after discovering a figure was compromised by “several unintentional anomalies in the background image.”
For one, many of the images were copied from another paper. In addition, one of the authors did not disclose that he was the president of a related company, nor that his company provided reagents for the experiments.
A group of Harvard stem cell researchers who already have one retraction and an expression of concern now have a correction. This one’s in Circulation Research, and it involves an image that previously had been flagged as suspicious in our comments.
The group is led by Piero Anversa, who as we reported last year is one of two researchers suing Harvard because the institution’s investigation into their work
has cost them millions in a forfeited sale of their company, and job offers.
A team of researchers whose work is under investigation by University College London has retracted a second paper.
