Duke lung researcher up to seven retractions

Enviromental Health Perspectives

More journals have pulled papers co-authored by researchers Erin Potts-Kant and Michael Foster, at Duke University, bringing the total up to seven for Potts-Kant and six for Foster.

Authors were unable to replicate the experiments after “concerns about the initial data from the animal physiology laboratory” led them to reanalyze source data, according to the note in Environmental Health Perspectives. The comparison showed “potential inconsistencies in the data,” which “significantly impact the overall conclusions of the manuscript.” Similar issues appear to have felled the pair’s other papers, including the other two recent retractions in the American Journal of Respiratory and Critical Care Medicine and the American Journal of Physiology – Lung Cellular and Molecular Physiology — but in the latter case, the discrepancies don’t affect the conclusion.

Potts-Kant was arrested on embezzlement charges in 2013. Authorities alleged that she stole almost $15,000 from Duke University.

Environmental Health Perspectives posted a retraction in July, for a 2012 paper that looked at the molecular underpinnings in airways that react to ozone.

Here’s the full notice:

Retracted paper on herbicide-ovarian cancer connection republished

ehpA retracted 2008 paper originally flagged by Clare Francis has been republished in Environmental Health Perspectives with updated figures and new data.

According to the editor’s note appended to the newly published paper, there was no evidence of intentional misconduct on the part of the authors. The new paper went through peer review as an entirely new submission, and comes to the same conclusion as the original:  Continue reading Retracted paper on herbicide-ovarian cancer connection republished

Herbicide-ovarian cancer study to be retracted

ehpThe authors of a 2008 study purporting to explain how the herbicide atrazine acts on cancer cells have asked the journal that published it to retract it for “inadvertent errors,” Retraction Watch has learned.

The notice for “G-Protein-Coupled Receptor 30 and Estrogen Receptor-a are Involved in the Proliferative Effects Induced by Atrazine in Ovarian Cancer Cells,” published in Environmental Health Perspectives, will read: Continue reading Herbicide-ovarian cancer study to be retracted

ORI finds Parkinson’s-pesticides researcher guilty of faking data; two papers to be retracted

The U.S. Office of Research Integrity (ORI) has found that a neuroscientist who studied the effects of pesticides on a mouse model of Parkinson’s disease made up data.

As The Scientist reported on Friday, the ORI found that Mona Thiruchelvam faked cell counts in two grant applications and a number of papers that claimed to show how the pesticides paraquat, maneb, and atrazine might affect parts of the brain involved in Parkinson’s. The Scientist notes: Continue reading ORI finds Parkinson’s-pesticides researcher guilty of faking data; two papers to be retracted
