The corresponding author for both papers, Hung-Chuan Pan of Taichung Veterans General Hospital, had contacted the journal about publishing an erratum for one of the articles when the journal was tipped off by an email pointing out deeper problems in the two retracted papers.
The tipster provided evidence that alleged “a violation of ethics on the part of the authors,” according to the communications manager at the JNS Publishing Group, Jo Ann Eliason.
Both retraction notices, published October 2, detailed a number of “similarities” and “overlaps” in the papers.
A paper about the molecular details of lung cancer is being retracted for repeating datasets and “careless errors” in a pair of figures.
According to the note, the editor of Carcinogenesis wouldn’t have known about the problems if he hadn’t been tipped off that the paper by first author, XiaoJuan Sun — a researcher at Shenzhen Second People’s Hospital in China — shared “significant similarities” with another one of Sun’s papers that was retracted years ago. After the journal investigated the paper, it discovered that the authors had reported the same data as in the retracted paper “without significant additions or amendments,” along with some errors and inconsistencies.
Here’s the detailed note for “The EDA-containing cellular fibronectin induces epithelial mesenchymal transition in lung cancer cells through integrin α9β1-mediated activation of PI3-K /Akt and Erk1/2:”
The authors of a Cell Metabolism paper are pulling it after discovering blot images that “appear more than once in independent and unrelated experiments.”
Just how the duplication occurred in the 2009 paper — about transcription of mitochondrial DNA — remains a mystery, the authors note:
…the reasons for the errors are still under investigation…
Meanwhile, we’ve learned that the last author on the paper — Carlos Moraes of the University of Miami — has requested a retraction for another 2013 paper in Mitochondrion, also co-authored by Tina Wenz at the University of Cologne in Germany. That paper is among multiple publications co-authored by Moraes and Wenz that have been flagged on PubPeer.
We’ve reached out to the parties involved, and received a warning from an attorney representing Wenz that if we write about Read the rest of this entry »
A journal has retracted a duplicate version of a case report about a patient with Parkinson’s disease after mistakenly publishing the paper twice.
The Journal of Movement Disorders initially published the report — which detailed the case of an elderly woman with Parkinson’s disease whose symptoms worsened during drug treatment — in 2010. But it ended up printing it again in 2011 because of “a mistake of the editorial office and the publisher.”
The notice reads:
In August, we reported on a clinical trial on hundreds of hypertensive patients that was published six times. Now, copies published in Expert Opinion on Drug Safety and Journal of the American Society of Hypertension (JASH) have been retracted, making for a total of three retractions for the group of papers.
The authors have defended the papers as being decidedly “different,” but one of the latest retraction notes points to an earlier retraction by some of the same authors (including first author Giuseppe Derosa, at the University of Pavia in Italy) for publishing two papers that “contain considerable text that is duplicative.”
Inflammation editor in chief Bruce Cronstein, who retracted one of the six duplicated papers from the clinical trial, told us in August that he and the editors of the other journals were all contacted “en masse” by an author doing a Cochrane Review on hypertension, who noticed that all six papers were “nearly identical.”
Just recently, we received a statement from the authors — sent by corresponding author Derosa — which argued that even if six papers stem from one trial, each was decidedly “different:”
Countries that publish less science appear to “borrow” more language from others than other, more scientifically prolific countries, according to a new small study.
Using a novel approach of comparing a country’s total citations against its total published papers (CPP), the authors categorized 80 retractions from journals in general and internal medicine. This is a relatively small number of retractions from one specific field of research; still, they found that:
Thus, retractions due to plagiarism/duplication were 3.4 times more likely among low-CPP countries than among high-CPP countries.
The CPP authors’ suggested interpretation? Read the rest of this entry »
Aspergillus spores are often ubiquitous yet harmless, but can irritate people whose lungs aren’t in top working order. Duplication, on the other hand, is more universally deadly. The editors of The Pan African Medical Journal told us that, in addition to the retraction, there were personal consequences for the authors: Read the rest of this entry »
A sixth paper co-authored by plant researcher Olivier Voinnet has been retracted by PLOS Pathogens “following an investigation into concerns.”
The investigation found “several band duplications” in one figure provided by fifth author, Patrice Dunoyer, who took it from “the Master thesis of a former student working under his supervision, without the prior consultation or consent of this student,” according to the notice. There was also an incorrect “loading control” in another figure, attributed to first author Raphael Sansregret and last author Kamal Bouarab.
Voinnet and Bouarab, the study’s corresponding authors, took full responsibility for “the publication of this erroneous paper.”
Although investigators found that the raw data in the duplicated figure backed up its conclusions, “given the nature and extent of data manipulation,” the authors asked the journal to retract the paper .
A paper on an equation useful in finance has been retracted after editors discovered an “identical” version had been published in another journal.
The paper, “On the Parametric Interest of the Black-Scholes Equation,” was published in the Thai Journal of Mathematics. According to the introduction, that equation has a practical use:
In financial mathematics, the famous equation named the Black-Scholes equation plays an important role in solving the option price of stocks
(According to The Guardian, it was “The mathematical equation that caused the banks to crash.”)
Here’s the retraction note in full:
A 2010 paper on plant fungus has been retracted after a comment on PubPeer revealed that a study image had been flipped over and reused to represent two different treatments.
In May, a commenter pointed out the plants in Figure 2a of the paper in the journal Molecular Plant-Microbe Interactions “look remarkably similar.” A commenter writing under the name of corresponding author, Yukio Tosa at Kobe University in Japan, posted a response two days later agreeing with the assessment and stating that the paper should be retracted.
