Researcher committed misconduct “recklessly,” says investigation

American Journal of Physiology Renal PhsyiologyA physiology journal has retracted a paper after an institutional investigation found that portions of the work had been falsified by the first author.

According to the notice issued by the American Journal of Physiology – Renal Physiology (AJP), the last author initiated the investigation at the University of Houston in Texas, which found the first author — Mousa Abkhezr — to be guilty of falsifying and duplicating images. 

We’ve obtained a copy of the investigation report, which concluded that Abkhezr committed misconduct “recklessly,” and the paper must be retracted. Although the report noted that Abkhezr argued that the problems stemmed from an honest error, the investigation committee ruled that data from the retracted paper cannot be included in his doctoral thesis.

The last author told us there is a separate ongoing “academic honesty enquiry” into Abkhezr’s dissertation. 

Here’s the retraction notice: Continue reading Researcher committed misconduct “recklessly,” says investigation

Investigation raises questions about top cancer researcher’s work

Journal of Pathology

A prominent pancreatic cancer researcher has lost a meeting abstract and corrected a Nature paper following an institutional investigation.

Queen Mary University of London determined that, in an abstract by Thorsten Hagemann, “elements of the study summarised by this abstract are not reliable.” Hagemann has recently issued a correction to a 2014 Nature paper he co-authored, which also cited the Queen Mary University of London (QMUL) investigation, noting there was “reason to question the provenance of the data.”

Hagemann is currently the medical director of Immodulon Therapeutics, and has long been recognized for his work in the field, including a three-year grant of £180,000 from the Pancreatic Cancer Research Fund in 2013.

Here’s the retraction notice from the The Journal of Pathology, regarding an abstract from the 7th Joint Meeting of the British Division of the International Academy of Pathology and the Pathological Society of Great Britain & Ireland: Continue reading Investigation raises questions about top cancer researcher’s work

Do publishers add value? Maybe little, suggests preprint study of preprints

ArXiv

Academic publishers argue they add value to manuscripts by coordinating the peer-review process and editing manuscripts — but a new preliminary study suggests otherwise.

The study — which is yet to be peer reviewed — found that papers published in traditional journals don’t change much from their preprint versions, suggesting publishers aren’t having as much of an influence as they claim. However, two experts who reviewed the paper for us said they have some doubts about the methods, as it uses “crude” metrics to compare preprints to final manuscripts, and some preprints get updated over time to include changes from peer-reviewers and the journal.

The paper, posted recently on ArXiv, compared the text in over 12,000 preprint papers published on ArXiv from February 2015 to their corresponding papers published in journals after peer review.

The authors report in their paper, “Comparing published scientific journal articles to their pre-print versions:” Continue reading Do publishers add value? Maybe little, suggests preprint study of preprints

Engineering journal pulls two papers for “compromised” peer review

The Open Mechanical Engineering Journal

An engineering journal has retracted two papers for faked or rigged peer review, but authors of one of the papers are objecting to the retraction. 

The first author of that paper told us he and his co-authors “absolutely disagree” with the retraction, and are prepared to use “legal means” to safeguard their “rights and interests.” He added: 

…my paper was published by normal ways, I don’t know why the peer review process was compromised and what the journal found in its investigation.

Here’s the retraction notice, which is similar for both papers: Continue reading Engineering journal pulls two papers for “compromised” peer review

Authors retract PNAS paper suggesting silk stabilizes vaccines

PNASA PNAS paper that caught the media’s attention for suggesting that adding silk could stabilize vaccines and antibiotics has been pulled after the authors realized there were significant errors in the data analysis. 

According to the notice, the authors agreed to retract the 2012 paper; however, the corresponding author told us the authors did not think a retraction was required as, according to him, the conclusions remained valid.

The paper presented a solution to the long-standing problem that sensitive biological compounds such as vaccines and antibiotics begin to lose their effectiveness outside the recommended temperature range, and naturally biodegrade over time. The degradation process cannot be reversed, and may even speed up during transport or storage under less ideal temperatures.

Here’s the retraction notice: Continue reading Authors retract PNAS paper suggesting silk stabilizes vaccines

Authors pull Nature paper about DEET and flies

Nature CoverAuthors have retracted a Nature paper which identified neurons that render flies sensitive to a potent insect repellent, after losing confidence in the findings. The first author, however, said she does not agree with the retraction, noting that she continues to believe the data are correct.

According to the notice, the remaining authors say they no longer support the claim that certain neurons in the antennae of fruit flies are repelled by DEET, the active ingredient in many insect repellents. The last author told us some of the paper’s results are not in doubt; nevertheless, he added, the paper would not have been published in Nature without the key conclusion, so he and most of his co-authors have pulled the paper in its entirety.

Alongside the retraction, the journal has also published a Brief Communications Arising article by scientists who were unable to reproduce the paper’s findings.

Here’s the retraction notice, published today:

Pharmacology journal pulls paper for “insufficient scientific quality;” authors disagree

Frontiers in PharmacologyAgainst the authors’ wishes, a pharmacology journal has retracted a paper after receiving two messages questioning the “soundness of the experimental results.”

The editors of the journal, Frontiers in Pharmacology, issued an expression of concern about the paper in April 2016, and investigated it following the allegations. According to the retraction notice, the authors disagree with the retraction.

Here’s the retraction notice for the paper: Continue reading Pharmacology journal pulls paper for “insufficient scientific quality;” authors disagree

Authors pull 4 papers from surgery journal for plagiarism

BMC SurgeryThe authors of four papers have pulled them for “significant overlap” with other publications, as well as borrowing “large portions of text” — in other words, plagiarism.

Two of the newly retracted papers published in BMC Surgery also listed co-authors who were “not involved in the study;” a similar note appears for an additional 2015 retraction that we’ve found for one of the authors.

That one author is listed on all of the newly retracted papers: Bruno Amato of the University Federico II of Naples, Italy.

Here’s the retraction notice for “Peripheral blood mono-nuclear cells implantation in patients with peripheral arterial disease: a pilot study for clinical and biochemical outcome of neoangiogenesis,” which has been cited five times since it was published in November, 2012, according to Thomson Reuters Web of Science: Continue reading Authors pull 4 papers from surgery journal for plagiarism

Researcher accused of fraud, embezzlement acquitted by Italian court

University of PerugiaAn Italian court has acquitted a gastroenterologist who was accused of fraud and embezzlement.  

An earlier institutional investigation into Stefano Fiorucci, based at the University of Perugia in Italy, found that he had manipulated images in publications that he allegedly used to win two million Euros of funding. The story, which has dragged on for years, has resulted in four retractions and nine expressions of concern for publications authored by Fiorucci. 

Fiorucci’s lawyer, Stefano Bagianti, told us: Continue reading Researcher accused of fraud, embezzlement acquitted by Italian court

JAMA journals pull 3 papers by same authors for misconduct

JAMAJAMA and another journal in its network have retracted three 2005 papers about preventing hip fractures, after an admission of scientific misconduct. 

All papers are being retracted over concerns about data integrity, and “inappropriate assignment of authorship.” Four of the authors — all based in Japan — have co-authored all of the three newly retracted papers, and also share authorship of a previous retraction from 2015. 

The JAMA paper was tagged with an Expression of Concern last year, regarding the “conduct, integrity, and scientific validity” of the paper. 

Here’s the retraction notice for the JAMA paper, “Effect of Folate and Mecobalamin on Hip Fractures in Patients With Stroke:” Continue reading JAMA journals pull 3 papers by same authors for misconduct
