Authors retract tanning-UV radiation study for lacking approval

Researchers have agreed to pull a 2015 study exploring whether a plant extract can safeguard tanners from ultraviolet exposure after not obtaining formal approval from an ethics committee.

According to the first author, the problem lay in a misunderstanding – when they originally applied for approval six years ago, the researchers believed they didn’t need to go through a formal approval process, since the compound was commercially available without a prescription. Once they realized their mistake, they chose to retract the paper.

Here’s the retraction note for “Oral Polypodium leucomotos increases the anti-inflammatory and melanogenic responses of the skin to different modalities of sun exposures: a pilot study,” published in Photodermatology Photoimmunology & Photomedicine.  Continue reading Authors retract tanning-UV radiation study for lacking approval

Journal retracts surgery study with data “not intended for use in research”

A journal has retracted a surgery study by researchers at Brown University after noticing it included data that was not intended for research purposes. (Incidentally, the data were collected by the publisher of the journal.)

Ingrid Philbert, managing editor of the Journal of Graduate Medical Education — which published the paper — told Retraction Watch that senior staff at the publisher alerted the journal that they suspected the authors had used data from a confidential source:

This is a fairly new set of case log data, and as the collector [of] the data, the [Accreditation Council for Graduate Medical Education (ACGME)] gets to determine the use and it has decreed that this data be used solely for accreditation decisions.

Philbert said the journal asked the authors where they got the data:

Nature paper with massive correction can’t be reproduced, says independent group

In 2011, authors of a Nature letter caught some flak for issuing a lengthy correction to a neuroscience paper that had raised eyebrows within days of publication — including some suggestions it should be retracted.

The correction notice, published months after the original letter, cited errors in image choice and labeling, but asserted the conclusions remained valid.

Now, those conclusions appear up for debate. In a recent Nature Brief Communications Arising (BCA) article, a team that raised concerns about the paper five years ago says they are unable to reproduce the results. But the authors of the original paper aren’t convinced: They argue that the BCA fails to cite important evidence, has a “complete absence or low quality of analysis,” and the scientists disregard some of their data.

“An example for all authors to uphold:” Researcher logs 5 corrections

A scientist in Ireland has corrected five of his papers in a single journal dating back more than a decade, after image-related problems were brought to his attention.

Four of the newly corrected papers have a common last and corresponding author: Luke O’Neill of Trinity College Dublin in the Republic of Ireland. O’Neill is also a co-author of the remaining paper that was fixed. O’Neill told us the mistakes were a “bit sloppy,” noting that he takes responsibility for the errors in the four papers on which he is last author.

O’Neill forwarded Retraction Watch a comment he received from Kaoru Sakabe — data integrity manager at the American Society for Biochemistry and Molecular Biology (which publishes The Journal of Biological Chemistry (JBC)) — that reads:

Japan group earns 4th retraction following investigation

Researchers in Japan have issued their fourth retraction, noting that the same figures were used to depict different experimental conditions.

The group lost two papers in 2015 for the same reason, following a misconduct investigation at Oita University in Japan. Last year, the same group notched another retraction, and pegged the responsibility for the problematic figures on first author Satoshi Hagiwara.

Now, the group has published a fourth retraction in the European Journal of Pharmacology; the latest notice doesn’t identify a culprit. All four retracted papers list Hagiwara as first author.

Here’s the latest retraction notice: Continue reading Japan group earns 4th retraction following investigation

Plant journal flags fungus paper amid investigation

A journal has issued an expression of concern (EOC) for a recently published study after a probe identified “problems with the figure presentation.”

According to the EOC notice in New Phytologist, two figures in the paper contained “some anomalies,” and the corresponding author has acknowledged that there are problems with the images.

Here’s the EOC notice: Continue reading Plant journal flags fungus paper amid investigation

Authors use same images in two studies — one is retracted, the other flagged by journal

After researchers in China included the same images in two papers published online one month apart, one paper has been retracted, and the other flagged with an expression of concern. 

According to the retraction notice in the International Journal of Molecular Medicine (IJMM), the authors intended that the two different papers offered “different research perspectives.”

Meanwhile, the Chinese Medical Journal — which published the same images one month later — has issued an expression of concern (EOC), noting it “should not be considered as a statement regarding the validity of the work.” Both papers describe how cells regulate blood flow to the retina.

Normally, journals choose to retract the most recent paper containing duplicated images, but in this case, the IJMM paper was published online in February 2016, and the Chinese Medical Journal in March.

Here’s the retraction notice: Continue reading Authors use same images in two studies — one is retracted, the other flagged by journal

Prominent researcher in Taiwan loses another paper for image duplication

In November, a vice president at an institution in Taiwan retracted a hotly debated cancer paper from Nature Cell Biology, citing image problems including duplications. Now, the Journal of Biological Chemistry has done the same, again citing image duplications.

There are a few things to note about the latest retraction: One, the last author is again Kuo Min-liang — who holds an appointment at National Taiwan University (NTU), and is also a vice president at Kaohsiung Medical University in Taiwan. Kuo is currently facing allegations that he accepted bribes to add co-authors to his papers; NTU told us it is investigating the latest retraction in the Journal of Biological Chemistry, including Kuo.

The other notable feature of the retraction is the notice itself, which lists a remarkable number of duplicated images. Take a look:

Researcher loses 4th paper flagged by misconduct probe

A researcher in Germany has logged her fourth retraction following an investigation by her former employer that found evidence of scientific misconduct.

The latest retraction for Tina Wenz in the Journal of Applied Physiology mentions the probe at the University of Cologne in Germany, which recommended retracting six of her papers. One had already been retracted by the time the report was released; last month, we reported that two others had been pulled. Now, we’ve come across a fourth.

Here’s the latest retraction notice: Continue reading Researcher loses 4th paper flagged by misconduct probe

Authors in Spain issue string of corrections

Following a journal probe and questions on PubPeer about their work, authors in Spain have issued four corrections, citing missing raw data for experiments conducted more than 10 years ago.

All papers include the same last two authors, Mireia Duñach at the Autonomous University of Barcelona, and Antonio García de Herreros at the Institut Hospital del Mar d’Investigacions Mèdiques.

Three of the corrections were issued by the Journal of Biological Chemistry, from which the authors retracted three papers earlier this year after a journal investigation concluded they contain reused images, designed to represent different experiments.

Duñach told us the latest corrections are the result of her own initiation:
