Analysis casts doubt on bone researcher’s body of work

19-coverA new analysis of more than 30 clinical trials co-authored by a bone researcher based in Japan is casting doubt on the legitimacy of the findings.

Yoshihiro Sato, based at Mitate Hospital, has already retracted 12 papers, for reasons ranging from data problems, to including co-authors without their consent, to self-plagiarism. Most of these retracted papers are included in the analysis in the journal Neurology, which concluded that Sato’s 33 randomized clinical trials exhibited patterns that suggest systematic problems with the results.

Other researchers have used similar approaches to analyze a researcher’s body of work — notably, when John Carlisle applied statistical tools to uncover problems in the research of notorious fraudster Yoshitaka Fujii, and Uri Simonsohn, who sniffed out problems with the work of social psychologist  Dirk Smeesters.

Author Mark Bolland of the University of Auckland told us he was surprised by his findings: Continue reading Analysis casts doubt on bone researcher’s body of work

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

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

Journal pulls plug on paper that predicts person’s death, against authors’ objections

frontier-in-human-neuroscienceSome people can look at an old photograph of a person — say, of your grandmother in elementary school — and tell whether the person is today alive or dead, according to a paper published last spring.

If that sounds too weird to be true…well, it might be. The journal editors have retracted the paper for not having enough evidence to back up its claims, despite the authors’ objections.

Here’s the retraction notice for “Prediction of Mortality Based on Facial Characteristics,” published in Frontiers in Human Neuroscience:

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?

Former Duke researcher at center of lawsuit lodges 16th retraction

ajrcmb-2016-55-issue-5-coverTwo former researchers at Duke University at the center of a lawsuit by a whistleblower to recoup millions in federal funding have lost yet another paper.

This is hardly the first retraction for Erin Potts-Kant, who used to work in the pulmonary lab of now-retired William Michael Foster. Earlier this year, a lawsuit filed by a former colleague of Potts-Kant and Foster was unsealed alleging that the pair — along with the university — included fraudulent data in materials involving more than 60 grants, worth hundreds of millions of dollars.

That is the legal side of their story. The science publishing side is that Potts-Kant and Foster have been steadily adding to their list of retractions — this paper represents her 16th, and his 13th.

Here’s the notice for “Nitric oxide mediates relative airway hyporesponsiveness to lipopolysaccharide in surfactant protein A-deficient mice:” Continue reading Former Duke researcher at center of lawsuit lodges 16th retraction

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

A biologist at the University of Georgia has lost a paper after an investigation revealed she had tampered with three images.

In 2014, Azza El-Remessy notched three retractions for a series of image errors. Now, a fourth retraction notice, and an expression of concern, explain there has been an investigation into her work. The investigation — conducted by two Georgia institutions, along with the Charlie Norwood Veterans Affairs Medical Center, where El-Remessy has additional appointments — has found evidence of misconduct.

The retraction notice for “Oxidative stress inactivates VEGF survival signaling in retinal endothelial cells via PI 3-kinase tyrosine nitration” explains:

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
