Five papers by prominent cardiologist Hiroaki Matsubara subject to Expression of Concern

Hiroaki Matsubara

The American Heart Association, which publishes a number of journals, has issued an Expression of Concern about five papers in three of their publications, following allegations of image manipulation. All of the papers include Hiroaki Matsubara, of Kyoto Prefectural University, as a co-author.

The notice begins:

It has come to the attention of the American Heart Association (AHA), in a public manner, that there are questions concerning a number of figures in several AHA journals’ articles…

The “public manner” was three posts last year on the Abnormal Science blog, available here, here and here, alleging that images were manipulated in the manuscripts, and that histology slides were reused.

The notice continues: Continue reading Five papers by prominent cardiologist Hiroaki Matsubara subject to Expression of Concern

Missouri medical board reprimands Anil Potti

Anil Potti, the former Duke oncology researcher who has now retracted ten papers amid continuing investigations into his work, has been reprimanded by the Missouri medical board.

The reprimand, which was first reported by DukeCheck, became effective on March 6. In it, the Missouri State Board of Registration for the Healing Arts noted that the North Carolina medical board had reprimanded Potti in November after he had Continue reading Missouri medical board reprimands Anil Potti

Plagiarism leads to seven retractions (and counting) in the conservation literature

Serge Valentin Pangou

An ecology researcher in the Congo has found himself at the center of a plagiarism scandal that has felled seven of his papers.

As Science reports today, Serge Valentin Pangou’s work began unraveling in August 2011 after Wageningen University ecologist Patrick Jansen thought a paper he’d been asked to review for the International Journal of Biodiversity and Conservation seemed familiar — because he’d written many of the same words in a 2007 paper in Conservation Biology. He ran the manuscript through the plagiarism detection software Turnitin, and sure enough, it was about 90% identical.

Unfortunately for Pangou, Jansen’s co-author on the Conservation Biology paper was Pierre-Michel Forget, whose father, as Science notes, “was a well-known private detective in France.” Forget and Jansen took a careful look at a number of Pangou’s papers, Continue reading Plagiarism leads to seven retractions (and counting) in the conservation literature

Author who took responsibility for errors in retracted PNAS paper cites it…in error

One of the issues we’ve touched on at Retraction Watch is what happens once papers are retracted. A few studies have found that other authors continue to cite those studies anyway, without noting their withdrawal from the literature. A more recent paper found that retractions are linked to a dramatic decline in citations (see last half of post). And we’ve reported on one case in which the authors of a retracted study decided not to cite it at all when they republished their findings elsewhere.

But it seems unusual for an author to cite his or her own retracted work without noting it had been retracted. That’s what happened in a recently published PLoS ONE paper, “Loss of Secreted Frizzled-Related Protein 4 Correlates with an Aggressive Phenotype and Predicts Poor Outcome in Ovarian Cancer Patients.” The second to last paragraph of that paper ends: Continue reading Author who took responsibility for errors in retracted PNAS paper cites it…in error

Two more retractions in respiratory journal as University of Louisville completes investigation

That investigation has apparently concluded, according to a retraction notice in the American Journal of Respiratory Cell and Molecular Biology for two of their papers: Continue reading Two more retractions in respiratory journal as University of Louisville completes investigation

Journal retracts paper “whose topic bears no relationship whatsoever” to publication’s subject matter

The journal Molecules has retracted a paper — “A comparative study of nozzle/diffuser micropumps with novel valves” — that they apparently never should have published in the first place.

JAMA awaiting final OHRP decision on Harvard-led paper whose authors didn’t fully disclose risks to elderly

Earlier this month, the U.S. Office for Human Research Protections (OHRP) told a group of researchers led by a Harvard Medical School professor that they hadn’t been forthcoming enough about the risks elderly subjects faced in their trial.

As the Boston Globe reported: Continue reading JAMA awaiting final OHRP decision on Harvard-led paper whose authors didn’t fully disclose risks to elderly
