Group retracts Nature Immunology paper for figure irregularities after posting a correction to Science

We’re following the case of a group that recently retracted a Nature Immunology paper for figure irregularities, soon after being forced to correct images in a Science paper for similar reasons.

The Nature Immunology paper, “The helminth product ES-62 protects against septic shock via Toll-like receptor 4–dependent autophagosomal degradation of the adaptor MyD88,” has been cited just twice since it appeared online in February 2011, according to Thomson Scientific’s Web of Knowledge. The retraction notice, which appeared online on July 19: Continue reading Group retracts Nature Immunology paper for figure irregularities after posting a correction to Science

Another retraction of IRB-free paper from Aussie sports medicine group

There’s another retraction from the Australian researchers who failed to obtain institutional review board (IRB) approval for their studies of rugby players and footballers.

The 2010 paper, in BMC Musculoskeletal Disorders — which had already retracted two other articles from the group — was titled “The effect of a sports chiropractic manual therapy intervention on the prevention of back pain, hamstring and lower limb injuries in semi-elite Australian Rules footballers: A randomized controlled trial.”

The editor of the journal had added this comment to the PDFs associated with the paper on August 3, a day after our post on the previous two retractions: Continue reading Another retraction of IRB-free paper from Aussie sports medicine group

Publishing scandal costs nursing researcher his post at online university

Scott Weber

Scott Weber, the nursing researcher accused of manipulating references and other publishing misconduct in at least seven retracted articles, has lost his position at Walden University, Retraction Watch has learned.

We noticed the other day that Weber’s name had disappeared from the Walden website and put in a call to the institution. A source there told us that Weber — a part-time faculty member who had been hoping for a full-time appointment at the school — apologized when confronted about the fraud.

The source, who did not want to be identified, said Continue reading Publishing scandal costs nursing researcher his post at online university

Duke sued over Potti case

From the “not terribly surprising” department: Eight patients — or their estates — who enrolled in clinical trials at Duke overseen by Anil Potti and colleagues have sued the university.

The 90-page lawsuit, which names Duke, Potti, Potti’s boss Joseph Nevins, CancerGuide Diagnostics (in which Potti and Nevins had an interest), among others, does a thorough job of documenting the case. In particular, it reviews the history of the trials, which were stopped in 2009, restarted, and then stopped for good as more and more issues came to light. It emphasizes, as you would expect, that Duke and the Potti team were warned repeatedly about problems in their work, notably by Keith Baggerly and a colleague.

Potti and colleagues have, as Retraction Watch readers will remember, now retracted five papers.

The plaintiff’s attorney, Thomas Henson, told Raleigh-Durham’s ABC11: Continue reading Duke sued over Potti case

Dutch university investigating psych researcher Stapel for data fraud

Tilburg University in the Netherlands has suspended the prominent social psychologist Diederik Stapel over concerns that he fabricated data in his published studies. According to a translation of a press release from the school, Stapel, professor of cognitive social psychology and dean of Tilburg’s School of Social and Behavioral Sciences, “has committed a serious breach of scientific integrity by using fictitious data in his publications.”

The release says the rector of Tilburg has set up a committee to investigate Stapel’s manuscripts and report back by October. Heading the panel is W.J.M. Levelt, former* president of the Royal Dutch Academy of Sciences and professor emeritus at the Radboud University in Nijmegen.

What the release does not specify, however, is which of Stapel’s many publications — a Medline search comes up with at least 45 bearing his name — are implicated. Continue reading Dutch university investigating psych researcher Stapel for data fraud

Montreal Heart Institute researcher dismissed following two retractions for image manipulation

A Montreal Heart Institute researcher who retracted two papers less than a month ago has been fired from his post.

Zhiguo Wang, who had been funded by the Canadian Institute of Health Research and the Canadian Diabetes Association, studied the genes linked to heart rhythm abnormalities, among other subjects. Wang also has an appointment at the University of Montreal.

As first reported in Retraction Watch, Wang withdrew two papers for the Journal of Biological Chemistry (JBC) in the journal’s August 12 issue. The story was quickly picked up by Postmedia and the CBC. At the time, Wang told us: Continue reading Montreal Heart Institute researcher dismissed following two retractions for image manipulation

Plagiarism in Indian Journal of Dermatology earns Tunisian authors a 5-year submission ban

The U.S. Department of Health and Human Services’ Office of Research Integrity (ORI) has found that a Boston University cancer researcher made up experiments reported in two papers funded by National Cancer Institute and National Institutes of Health grants. According to the ORI notice:

Sheng Wang, PhD, Boston University School of Medicine Cancer Research Center: Based on the Respondent’s acceptance of ORI’s research misconduct findings, ORI found that Dr. Sheng Wang, who has been an Assistant Professor, Department of Medicine, Boston University School of Medicine Cancer Research Center (BUSM), engaged in research misconduct in research supported by National Cancer Institute (NCI), National Institutes of Health (NIH), grants R01 CA102940 and R01 CA101992.

The two papers were: Continue reading Two papers to be retracted after ORI finds misconduct by Boston University cancer researcher

Authors retract two JBC papers on how heart rhythms go awry; Montreal Heart Institute looking into why

The authors of two Journal of Biological Chemistry (JBC) studies of the molecular underpinnings of hearts whose rhythms have gone awry have retracted the papers, for reasons that are not completely clear.

The two papers are  “MicroRNA miR-133 represses HERG K+ channel expression contributing to QT prolongation in diabetic hearts,” published in 2007, and “Down-regulation of miR-1/miR-133 contributes to re-expression of pacemaker channel genes HCN2 and HCN4 in hypertrophic heart,” published in 2008.

This being the JBC, the retraction notices in the August 12, 2011 issue say nothing: Continue reading Authors retract two JBC papers on how heart rhythms go awry; Montreal Heart Institute looking into why
