U Colorado’s former “golden boy” up to 7 retractions

University of Colorado DenverA former graduate student at the University of Colorado Denver has gained three retractions and two expressions of concern (EOC), following an institutional probe into his work. 

Last year, we reported on an investigation by the University of Colorado Denver into the research of Rajendra Kadam, which recommended retracting 10 papers. The report also flagged eight additional papers co-authored by Kadam whose data could not be validated, raising “concerns as to the scientific validity and integrity” of the material. A few months later, we reported on some of the notices — four retractions and an EOC — that had begun to appear for Kadam’s manuscripts.

We’ve since discovered more notices, bringing his total to seven retractions and three EOCs. 

Kadam was once a prominent member in the lab of Uday Kompella, and often referred to by colleagues as the “golden boy,” according to the institution’s report. In 2012, he won a graduate student symposium award from the American Association of Pharmaceutical Scientists.

A nutrition researcher with multiple retractions who unsuccessfully sued the Canadian Broadcasting Corporation (CBC) for libel has been charged with defrauding a state health insurance plan.

The Toronto Star reports that a warrant has been issued for the arrest of Ranjit Kumar Chandra for billing the Ontario Health Insurance Plan for “services that were either not provided or billed inappropriately.” The charges do not appear to be related to his research: Chandra worked once a week as an allergist for the past four years, the Star reports, and the alleged fraud was at least $5,000.

A pharmacology researcher at Ohio State University has added his seventh retraction, four years after a finding of misconduct by the U.S. Office of Integrity (ORI).

An analysis of the work of Terry Elton determined that he had

falsified and/or fabricated Western blots in eighteen (18) figures and in six (6) published papers.

 In 2012, the ORI finding, which resulted in a three-year funding ban (that is now complete), recommended that Elton retract all six papers, one of which had already been retracted at the time of the report. 

Four years later, the last of the six papers flagged by the ORI has finally been retracted by Molecular and Cellular Endocrinology.

Here’s the retraction notice: Continue reading 7th retraction for Ohio researcher who manipulated dozens of figures

A tale of two retraction notices — for the same paper

curentHere’s a strange one: We discovered a paper about an antibiotic-resistant strain of bacteria that bore two retraction notices, and each provided a different reason for retraction. One alleged misconduct; that notice still appears now. The other — which has since disappeared — said the paper was submitted by mistake.

“In vitro effect of boric acid and calcium fructoborate esters against methicillinresistant Staphylococcus aureus strain” was published in the South-Western Journal of Horticulture, Biology and Environment. The full text isn’t available on the journal’s website.

First, here’s the text in the retraction notice that appears when one clicks on the “download full text” link in the table of contents next to the paper: Continue reading A tale of two retraction notices — for the same paper

A retraction cluster? Two papers retracted for overlap with other retractions

molecular biology reportA cluster of papers by different authors has been retracted for sharing text, even though some papers were submitted at the same time.

How is that possible? A spokesperson for Springer told us that they have reason to believe a third-party company may have helped prepare the papers for publication, and in the process might have spread the material around to multiple manuscripts.

The details of the cluster are a bit perplexing, so bear with us. Two of the papers — that were published only months apart — have already been retracted, as we reported in April. Now, two other papers have been retracted from Molecular Biology Reports — and both notices cite the previously retracted papers. The new notices also say that there’s reason to believe that the peer-review process was compromised.

All papers conclude that a certain polymorphism could signal a risk for coronary artery disease among Chinese people.

We’ll start with the retraction notice for “Fibroblast growth factor receptor 4 polymorphisms and coronary artery disease: a case control study,” which cites the two papers that were retracted previously:

Collateral damage: Paper — and editorial, and author’s response — retracted in one fell swoop

euro jA journal has retracted the results of a clinical trial comparing strategies for bladder tumors after the authors mischaracterized the way patients were assigned to each procedure.

In addition, the journal European Urology has pulled a string of correspondence between author Harry Herr at Memorial Sloan Kettering Cancer Center and an outside expert, who had questioned aspects of the study totally unrelated to the methodology, such as its generalizability.

Here’s the retraction notice for ” Randomized Trial of Narrow-band Versus White-light Cystoscopy for Restaging (Second-look) Transurethral Resection of Bladder Tumors:”  Continue reading Collateral damage: Paper — and editorial, and author’s response — retracted in one fell swoop

Journal pulls abstract author didn’t submit

A journal has retracted an abstract after discovering the author didn’t submit it — and also because it appears “highly similar” to a previous publication in Chinese.

The abstract was presented at the 2nd International Conference on Biomedicine and Pharmaceutics in 2014, and lists Qing Guo as the sole author, based Wuhan, China at the China University of Geosciences.

According to the retraction notice, published in the Journal of Investigative Medicine last December, the organizer of the conference discovered Guo hadn’t consented to publish the abstract — moreover, it appeared to overlap with another article in Chinese, written by different authors: Continue reading Journal pulls abstract author didn’t submit

Author of retracted math paper defends against plagiarism charge, threatens to sue journal

A researcher in Egypt is threatening to sue a mathematics journal if it doesn’t un-retract one of his papers.

The American Journal of Computational Mathematics in May retracted Mostafa M. A. Khater‘s 2015 paper, “The Modified Simple Equation Method and Its Applications in Mathematical Physics and Biology.” The retraction notice is sparse on the details, indicating only that the article was not up to snuff: Continue reading Author of retracted math paper defends against plagiarism charge, threatens to sue journal

Study of air quality around Damien Hirst’s artwork retracted — against most authors’ wishes

The corresponding author of the study that detected toxic leaks from the work of prominent British artist Damien Hirst has now retracted it — but most of his co-authors disagree with the decision.

The April Analytical Methods study was covered extensively by the media when it suggested staff at Damien Hirst’s 2012 exhibition at Tate Gallery in London of dead animals embalmed in formaldehyde were being exposed to higher than recommended levels of the carcinogen. 

Tate and Hirst’s company, Science Limited, immediately objected to the results; we’ve obtained what appears to be letter from a lawyer for Science Limited to the corresponding author of the paper — Pier Giorgio Righetti of the Polytechnic University of Milan in Italy — saying it was “deeply concerned and troubled by the claims” in the paper.

Last month, the journal issued an expression of concern (EOC) for the paper, nothing the data may not be reliable, and on July 15, Righetti announced in a joint statement with Hirst’s company that he will be retracting his study.

Now, the paper has been officially retracted, noting more recent measurements show formaldehyde levels to be much lower than originally reported. But most of Righetti’s co-authors disagree with the decision, the notice says:  Continue reading Study of air quality around Damien Hirst’s artwork retracted — against most authors’ wishes

Does dose matter? Tumor killer paper thought so, now must retract

Molecular Medicine ReportsAfter questions from a reader, researchers took a second look at their data about the effects of a vitamin A metabolite on tumor cells, and realized their key finding was inaccurate.

They’re now retracting the paper, from Molecular Medicine Reports, because it originally reported that higher concentrations of retinoic acid (RA) were more effective in curbing the proliferation of brain tumor cells. But it seems that the RA dose made less of a difference than they originally believed, according to the retraction notice:
