The Journal of Agricultural and Food Chemistry has retracted three papers by Dipak Das, the resveratrol researcher found to have committed more than 100 counts of fraud by the University of Connecticut.
Journal editor James Seiber writes: Continue reading Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry
The Spanish press has picked up on the story of a prominent veterinary scientist in that country who has been accused of research misconduct.
According to El Pais, the researcher, Jesús Ángel Lemus, whose areas of interest include the effects of toxins on birds, ran into trouble in December when colleagues complained to the Ethics Committee of the Higher Council for Scientific Research about the reproducibility of his results and other problems. That triggered an inquiry by the CSIC into Lemus’ body of work, an investigation that, evidently, could not find a body.
Per El Pais (courtesy of Google Translate): Continue reading Spanish veterinary researcher under suspicion of creating “ghost” author, fabricating data
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
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
There’s a bit more this afternoon on the story of Yoshitaka Fujii, the Japanese anesthesiologist accused of fraud and other misconduct that we reported on yesterday.
The British journal Anaesthesia, which has been looking into Fujii’s research record, has posted four articles and editorials about the case and related issues on its website. One in particular is remarkable for its conclusions. Written by a UK anesthesiologist named John Carlisle, the article claims to have analyzed 169 randomized controlled trials that Fujii conducted between 1991 and 2011.
According to the abstract (which we formatted for readability, and which should be online shortly, we’re told): Continue reading Update on Fujii: Anesthesia journal finds overwhelming statistical evidence of data fabrication
We have learned that a widely published Japanese anesthesiologist is under investigation by his university over concerns that he engaged in repeated fraud for decades that has tainted roughly 180 articles—many of which may be retracted as a result.
In a related move, the journal Clinical Therapeutics is retracting papers by the researcher, Yoshitaka Fujii, most recently of Toho University, in Tokyo. Judy Pachella, managing editor of the journal, confirmed the retractions but would not state how many papers were affected. Clinical Therapeutics published 17 articles by Fujii, between 2003 and 2010.
Bharat B. Aggarwal, the MD Anderson researcher under investigation at his institution over concerns of image manipulation, has withdrawn a second paper, although you’d never know why from the statement.
The notice for the article, “Evidence for the critical roles of NF-κB p65 and specificity proteins in the apoptosis-inducing activity of proteasome inhibitors in leukemia cells,” is pretty minimal: Continue reading Another withdrawal by MD Anderson’s Aggarwal, again for unclear reasons
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
Last July, we reported on four retractions by a group of researchers at the University of Louisville, and we noted that the scientists’ work was under 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
Last month, we reported on two retractions by the former neuroscience and physiology department chair at the State University of New York (SUNY) Upstate Medical University in Syracuse. Both of the retractions were requested by the university after an investigation found that Michael W. Miller had committed misconduct.
Now, the Office of Research Integrity (ORI), which reviews misconduct investigations by NIH grantee institutions, has weighed in. As detailed in the Federal Register, ORI found that Miller falsified or fabricated data in four NIH grant applications, the two published (and now retracted) papers, and one manuscript submitted to the Proceedings of the National Academy of Sciences (PNAS). For example, he Continue reading ORI: Former SUNY Upstate neuroscience dept. chair Miller manipulated data in four grant applications
