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

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

Hospitalization of participant in child psych study prompted misconduct inquiry: Letter

Mani Pavuluri

The adverse event that prompted the University of Illinois at Chicago to shutter three trials by a child psychiatrist occurred when one of the study subjects was hospitalized.

According to a 2013 letter obtained by Retraction Watch through a public records request, the subject was admitted to a 10-day inpatient treatment program after exhibiting an increase in irritability and aggression, which prompted researcher Mani Pavuluri to notify the university’s Institutional Review Board (IRB) in January of that year. As a result, the university halted three studies by Pavuluri, sent out letters to 350 research subjects, and launched a misconduct inquiry.

Here’s how the document describes the event (with some details blacked out): Continue reading Hospitalization of participant in child psych study prompted misconduct inquiry: Letter

Materials researcher falsified data in two studies, probe reveals

advanced-materialsA materials journal has retracted two 2013 papers, citing an investigation at Pennsylvania State University that concluded the first author falsified data.

According to the retraction notice in Advanced Materials, Mehdi Ghaffari — formerly based at Penn State — was solely responsible for the misconduct. Ghaffari’s LinkedIn page says he finished his PhD at Penn State in 2014, and now works as an independent consultant in New York, after a stint as a postdoc at Procter and Gamble.

Prominent heart researcher dismissed by Ontario university; colleagues appeal

Morris Karmazyn

Earlier this month, Morris Karmazyn, an award-winning cardiovascular researcher who’s published hundreds of papers, was called into a meeting with the office of faculty relations at the University of Western Ontario, and terminated.

The reason? A series of image problems in some of his papers, raised by a former member of his lab. When Karmazyn, Canada Research Chair in Experimental Cardiology, was told it was a case of “misconduct,” he was floored: Continue reading Prominent heart researcher dismissed by Ontario university; colleagues appeal

Journals flag two papers by psychologist Jens Förster

forster-j-a1Journals have flagged two papers by prominent social psychologist Jens Förster — whose work has been subject to much scrutiny — over concerns regarding the validity of the data. 

Förster already has three retractions, following an investigation by his former employer, the University of Amsterdam (UvA) in the Netherlands. In 2014, we reported on the first retraction for Förster for one of three studies with odd patterns that were flagged by the UvA investigation, a 2012 paper in Social Psychological and Personality Science; subsequently, the Netherlands Board on Research Integrity concluded that data had been manipulated. Three statistical experts from the UvA then carried out a more in-depth analysis of 24 publications by Förster, and found eight to have “strong evidence for low scientific veracity.”

Last year, Förster agreed to retract two more papers as part of a deal with the German Society for Psychology (DGPs); those retractions appeared earlier this year. All three papers that Förster has lost until now are from the “strong evidence for low scientific veracity” category. Recently, two more of Förster’s papers from the same category were flagged with notices, but not retracted.

One “statement of institutional concern,” issued by Personality and Social Psychology Bulletin, reads:
