Cancer researcher in Germany loses multiple papers after misconduct finding

A pathology journal is retracting two papers after an investigation at the last author’s institution in Germany found evidence of scientific misconduct.

The notice for both papers cites an investigation involving Regine Schneider-Stock, who studies cancer biology at the Friedrich Alexander-University Erlangen-Nuremberg (FAU). Meanwhile, another 2005 paper that lists Schneider-Stock as the first author was retracted in October, noting evidence of image manipulation.

The most recent retractions, from the American Journal of Pathology, note that FAU declined to provide the journal with details of its investigation beyond a prepared statement:

JAMA article on zinc for the common cold retracted

Authors have retracted a JAMA article summarizing the evidence behind the benefits of a supplement, after the systemic review upon which it was based was withdrawn.

The 2014 paper, “Oral Zinc for the Common Cold,” drew from a 2013 Cochrane Review, considered the gold standard for rigorous analyses of clinical treatments. That Cochrane review was withdrawn last year, a decision that the editors upheld this past September. Both were co-authored by Rashmi Ranjan Das, of the All India Institute of Medical Sciences, in Bhubaneswar, and Meenu Singh, of the Post-Graduate Institute of Medical Education and Research, in Chandigarh, India.

JAMA editor in chief Howard Bauchner told Retraction Watch that this week’s retraction followed an investigation by the journal: Continue reading JAMA article on zinc for the common cold retracted

EMBO journals retract figures in two papers missing source data

Journals published by the European Molecular Biology Organization (EMBO) have retracted a handful of figures in two papers with the same last and first authors.

After some figures in the 2005 and 2007 papers were flagged on PubPeer and the authors couldn’t provide the original data, the journals decided to retract parts of the papers, since other data supported the remaining conclusions, according to the Head of Scientific Publications at EMBO.

The partial retractions are labeled as corrigenda by the journals. Earlier this year, the U.S. National Library of Medicine (NLM) announced it would be classifying partial retractions as errata, noting they had been used so rarely by journals.

Both lengthy corrigenda (also reported by Leonid Schneider) contain statements from the authors and the editors. The statements from the authors provide detailed explanations about the problems with the figures in question; here’s an excerpt from the editor’s statement in The EMBO Journal corrigendum: Continue reading EMBO journals retract figures in two papers missing source data

Researcher logs three retractions for image duplications — two of which with familiar co-authors

A researcher in Brazil is taking responsibility for accidentally mixing up images in three papers in the Journal of Biological Chemistry. 

The corresponding author on the three papers told us the mistake happened because the studies were conducted simultaneously, and relied on one computer.

There’s a side note to these retractions: The co-author list on two papers includes names that should be fairly well-known to our readers — Mario Saad, the researcher who unsuccessfully sued the American Diabetes Association to stop retractions of his papers, and Rui Curi, a researcher whose legal threats assisted in the shutdown of Science-Fraud.org. This makes Saad’s ninth retraction.

According to the retraction notices, Lício Velloso  — who, like his co-authors, is based at the University of Campinas in São Paulo, Brazil — assembled all the figures. He told Retraction Watch that the authors initially wanted to correct the papers, adding: Continue reading Researcher logs three retractions for image duplications — two of which with familiar co-authors

Journal cleans the house by retracting 6 cancer papers for plagiarism

Following an investigation, a genetics journal has pulled six cancer papers published this year for plagiarizing from other sources.

According to an excerpt from the retraction notice in Genetics and Molecular Research, the journal has “strong reason to believe that the peer review process was [a] failure,” and has alerted the authors’ institutions.

The notice announcing the retraction of all six papers begins: Continue reading Journal cleans the house by retracting 6 cancer papers for plagiarism

Journal issues three notices for plant biologist, two citing manipulation

Researchers have retracted a paper from a plant journal after a probe found problems with several figures.

According to the new retraction notice in The Plant Cell, some figures in the paper were manipulated, as well as “inappropriately duplicated and reused from a previous publication.” The authors assert that they believe the conclusions remain valid.

The journal has also issued two corrections that include some of the same authors — including one that cites inappropriate image manipulation.

Here’s the retraction notice, issued last month: Continue reading Journal issues three notices for plant biologist, two citing manipulation

Co-author of retraction record-holder likely fabricated his own data, analysis shows

In 2012, John Carlisle, a British anesthesiologist, demonstrated conclusively using statistics that Yoshitaka Fujii had faked data in many studies. Fujii — as followers of this blog well know — now holds the record for most retractions by an individual author (183).

Carlisle’s work accomplished two things: It put to rest any doubt that problems with Fujii’s work might have resulted from innocent mistakes, and it gave journals a mathematical tool for conducting investigations into potential cases of misconduct.

Now comes the payoff. In a new paper, Carlisle and another anesthesiologist, John Loadsman, take aim at one of Fujii’s frequent co-authors, Yuhji Saitoh of Yachiyo Medical Center and Tokyo Women’s Medical University in Japan. The pair analyzed data from 31 studies Saitoh published between 1993 and 2012 — including one study that was rejected in 2015 — for a total of 32 papers. Of those, 23 did not include Fujii as an author.

Writing in the journal Anaesthesia, where Carlisle published his first study about Fujii, he and Loadsman state that: Continue reading Co-author of retraction record-holder likely fabricated his own data, analysis shows

Oops: Supposedly untreated cancer patients had surgery, after all

gmrThe first author of a 2016 paper has retracted it after realizing that all the lung cancer patients that were supposed to have been untreated did, in fact, have surgery to remove their tumors. 

Zhao Kai, the study’s first author from the Qilu Hospital of Shandong University and Zibo Central Hospital (both in China), took full responsibility for the error.

Here’s the retraction notice, published last month in Genetics and Molecular Research: Continue reading Oops: Supposedly untreated cancer patients had surgery, after all

Prominent cancer researcher committed nearly 30 acts of misconduct

An investigation into the lab of a prominent cancer researcher in British Columbia has revealed nearly 30 acts of misconduct.   

As we detail in our latest feature for Science, the investigation, at the University of British Columbia (UBC), uncovered 29 instances of scientific misconduct, 16 of which were characterized as “serious,” according to university correspondence obtained by Retraction Watch.

The researcher, Sandra Dunn, is prominent in her field, but she left UBC in 2015 under unclear circumstances, shortly after it concluded its investigation. Dunn now heads a private company, Phoenix Molecular Designs, which says it develops therapies for cancer patients and lists local charities among its “partners and supporters.” While at UBC, Dunn obtained at least $1.1 million dollars in Canadian federal funding, some of which was used to support the falsified studies.

To some of the people involved, the most unsettling part of the incident is that it appears Dunn still receives support from Canadian charities. Continue reading Prominent cancer researcher committed nearly 30 acts of misconduct

UCLA lab pulls two papers — one by author who admitted to misconduct

A lab at the University of California, Los Angeles has retracted two papers for duplicated images.

These retractions — in the Journal of Immunology — represent the second and third retractions for the lab head; he lost another paper after one of his former students confessed to manipulating images.

Although Eriko Suzuki admitted to her actions on PubPeer in 2014, the 2007 Oncogene paper wasn’t retracted until June, 2016, when the journal issued a notice citing “data irregularities.”

Unfortunately, Suzuki’s admission in 2014 wasn’t the end of the troubles for lab head Benjamin Bonavida, who recently issued two additional retractions in the Journal of Immunology, only one of which includes Suzuki as a co-author.

Bonavida told us the university received allegations (he’s not sure from who) that some of the control gels were duplicated; he didn’t agree, but couldn’t produce the original gels to disprove it. We asked if any more retractions were coming from Bonavida, who has since retired from running a lab:
