Two Harvard-led groups pull well-cited cancer papers for duplication

the-journal-of-clinical-investigationTwo sets of authors based largely at Harvard Medical School have each retracted a paper for duplication in the same journal.

Both papers — which are more than a decade old — were pulled in The Journal of Clinical Investigation on November 1 by their respective corresponding authors.

One paper’s last author told us it was difficult to identify how the duplications occurred since the study took place so long ago, but added that multiple experiments had corroborated the results.

Here’s the first retraction notice for “Complementary roles of IRS-1 and IRS-2 in the hepatic regulation of metabolism:” Continue reading Two Harvard-led groups pull well-cited cancer papers for duplication

Researcher denies faking reviews for 5 newly retracted papers

engineering-failure-analysisJournals have retracted five papers by a materials researcher based in Poland after concluding the peer-review process had been faked. 

According to the retraction notices — which all appear in Elsevier journals and contain the same text — the papers were accepted due to “positive advice of at least one faked reviewer report,” which were submitted from fictitious email accounts for reviewers suggested by the author.

All five studies were solely authored by Mariusz Książek, who is based at the Wrocław University of Science and Technology in Poland, and has denied any wrongdoing.

A spokesperson from the Wrocław University of Science and Technology confirmed that the university “has taken legal actions.” 

Książek told Retraction Watch why he doesn’t agree with the decision to retract his papers: Continue reading Researcher denies faking reviews for 5 newly retracted papers

Genetics study flagged for reliability issues by Frontiers journal

frontiers-in-geneticsA genetics journal has issued an expression of concern (EOC) for a study after an investigation by its chief editors.

According to the notice in Frontiers in Genetics, the authors of the paper — based at Hokkaido University in Sapporo, Japan — are conducting further experiments to resolve the issues raised by the journal’s investigation.

In February, the same paper received a corrigendum due to errors in the assembly of one of the figures.

Here’s the EOC, issued earlier this week: Continue reading Genetics study flagged for reliability issues by Frontiers journal

Danish university revokes PhD of anti-terrorism researcher

Anti-terrorism researcher Nasrullah Memon has lost his PhD after a committee in Denmark found he had plagiarized his doctoral thesis.

He’s also recently been let go by his latest employer, the University of Southern Denmark in Odense; a spokesperson for the university told us the decision stemmed from budgetary cutbacks, and was unrelated to the loss of his PhD.

We previously reported on 15 retractions for papers co-authored by Memon; in 2014, the Danish Committee on Scientific Dishonesty (DCSD) ruled that Memon’s thesis had been plagiarized.

In May this year, an official from Aalborg University (AAU) in Denmark — where Memon earned his PhD — told us the university was considering whether to revoke Memon’s PhD. They ultimately decided to do so, Inger Askehave, AAU’s pro-rector, told Retraction Watch: Continue reading Danish university revokes PhD of anti-terrorism researcher

Family decries publication of child’s picture in open access journal

indian-journal-of-dermatology-venereology-and-leprologyAn author of a paper about a boy with a rare genetic disorder has retracted it after the patient’s family revoked permission to use his photo.

The 2012 paper in the Indian Journal of Dermatology, Venereology and Leprology (IJDVL) told the tale of a 14-year old boy with Delleman syndrome, a condition that often results in the development of cysts within the cavities of the skull, leading to malformations in the eyes, brain, and skin.

Mabel Nocito, the study’s first and corresponding author from Hospital Churruca in Buenos Aires, Argentina told us the parents initially gave permission to publish their son’s picture, but then became concerned when they realized the paper was freely accessible: Continue reading Family decries publication of child’s picture in open access journal

Two journals, same name: Did one editor retract the other’s paper?

amphibian-and-reptile-conservationTwo journals sharing the same title — allegedly due to an “academic divorce” between the founders — are giving two different accounts to why a paper may (or may not) have been retracted.

Confused yet? We are.

Here’s what we can piece together. The journal Amphibian and Reptile Conservation once had two editors, Craig Hassapakis and Robert Browne; both names appear on the same cover of a 2011-2012 issue of the journal, as librarian Jeffrey Beall noted in a blog post published last year. But since then, there seems to have been an “academic split” between the two (as defined by Beall), and each now publishes a different version of the publication named Amphibian and Reptile Conservation.

Recently, we came across a 2013 paper co-authored by Browne marked “Retracted” on the version of the site founded by Craig Hassapakis. Browne’s version of the journal can be found here. 

Meanwhile, the study’s first author, Omar Fadhil Al-Sheikhly from the University of Baghdad in Iraq, claims the paper was never retracted in the first place: Continue reading Two journals, same name: Did one editor retract the other’s paper?

Authors retract third cancer paper for missing original data

international-journal-of-oncologyResearchers have retracted their third paper due to missing original data, following an investigation at their former institution in New York.

We’ve previously reported on two retractions of papers co-authored by Bhagavathi Narayanan and Narayanan K. Narayanan, previously based at the New York University (NYU) School of Medicine. The studies were pulled when the pair couldn’t provide original images to investigators at NYU School of Medicine. One author has blamed the lack of original data on the abrupt closure of her previous institution in 2004, after it allegedly misspent millions in federal grants. 

However, the latest retraction affects a paper published eight years later in the International Journal of Oncology. Its coauthors include Bhagavathi Narayanan, Narayanan K. Narayanan and Rajkishen Narayanan; we haven’t been able to uncover if there is a relation between them.

A spokesperson for the NYU School of Medicine sent us this statement: Continue reading Authors retract third cancer paper for missing original data

Leading diabetes researcher acted negligently, probe concludes

Kathrin Maelder
Kathrin Maedler

Several duplications in the work of a prominent diabetes researcher were the result of negligence, but there is not enough evidence to support charges of misconduct, according to an investigation at her university in Germany.

Recently, we’ve reported on several notices for papers co-authored by Kathrin Maedler, a researcher at the University of Bremen. So far, Maedler has one retraction, multiple corrections, and two expressions of concern to her name, after several of her papers were questioned on PubPeer. Previously, the University of Zurich in Switzerland — where Maedler completed her PhD in 2002 — determined there was a lack of evidence to support allegations of misconduct in papers that were part of her doctoral thesis. 

Last week, the University of Bremen released its own investigation report (in German), which we translated using One Hour Translation. It concludes that Maedler Continue reading Leading diabetes researcher acted negligently, probe concludes

Medical journal retracts study over fake review, authorship concerns

european-journal-of-medical-researchA journal has retracted a 2015 study about lung cancer after learning the peer-review process had been compromised.

The paper was published in March, 2015 — the same month publisher BioMed Central (BMC) pulled 43 papers for fake reviews.

According to the retraction notice in the European Journal of Medical Research, the authors’ institution in China informed the publisher that the authors had used a third party to help with copyediting and submission to the journal, raising concerns about the authorship of the paper.

Here’s the retraction notice, published in August: Continue reading Medical journal retracts study over fake review, authorship concerns
