Beleaguered plant scientist with 22 corrections avoids 3 more

CellCell will not be issuing corrections for three papers co-authored by prominent plant biologist Olivier Voinnet, after readers on PubPeer raised questions about some of the images. 

The news may be a welcome relief for Voinnet, based at ETH Zurich in Switzerland, who has recently issued 22 corrections and seven retractions. Ongoing questions about his work have also earned him a three-year funding ban, and caused the European Molecular Biology Organization to revoke an award.

On July 28, Cell published editorial notes for all three papers, which have been collectively cited more than 1000 times (also reported by Leonid Schneider). The notes say that the journal will take “no further action,” noting that the authors of the papers informed Cell of the problems with figures, which do not appear to compromise the papers’ overall validity.  

Here’s the first editorial note, for a 1998 paper: Continue reading Beleaguered plant scientist with 22 corrections avoids 3 more

A headache: Brain paper retracted over author argument

neurochemical researchResearchers have retracted a paper following an argument over who deserves top billing, according to the last author of the paper.

The last author added the authors plan to republish the paper once they work things out.

The work for the paper — about cell death in the aftermath of a brain hemorrhage — was started in one lab at the Department of Neurology at the Affiliated Hospital of Nantong University, and completed in another.

That led to a dispute, reports the retraction notice, issued by Neurochemical Research:

Cell Press dismisses fraud allegations in high-profile genetics papers

Screen Shot 2016-08-03 at 18.54.35Cell Press has dismissed accusations of image manipulation in two well-cited papers. 

In June 2015, we reported that the publisher was investigating anonymous allegations of more than a dozen instances of manipulation of images in the papers published in Cell and Molecular Cell in 1999 and 2001, respectively. 

After assessing the original high-resolution versions of images from the laboratory notebook of Maria Pia Cosma, the first author of both papers, the journals have not found enough evidence to determine that fraud had occurred. 

Here’s the editorial note, issued last week for both papers (and also reported by Leonid Schneider): Continue reading Cell Press dismisses fraud allegations in high-profile genetics papers

Biologist with five-year funding ban earns 7th and 8th retractions

Biology OpenA biologist in New Jersey has retracted two more papers, bringing his total to eight retractions, following a finding by the U.S. Office of Research Integrity (ORI).

The analysis of the work of John Pastorino, previously a cell biologist at Rowan University, in Glassboro, concluded that he had doctored more than 40 images, resulting in a five-year funding ban.

The report flagged eight published papers (and an unpublished one), six of which had already received expressions of concern (EOCs). Nataly Shulga was a co-author on all eight papers. With these two new retractions in Biology Open and Biochimica et Biophysica Acta (BBA) – Bioenergetics, all of the flagged papers have now been retracted.

Here’s the retraction notice for the Biology Open paper, issued July 15:

Researcher denied PhD after “recklessly” committing misconduct

Molecular PharmacologyA doctoral student at the University of Houston in Texas will not receive his PhD, following an institutional investigation into his work.

Mousa Abkhezr, the researcher in question, is no longer enrolled at the University of Houston, his former supervisor told us.

In June, the probe into papers co-authored by Abkhezr resulted in the retraction of a study in the American Journal of Physiology – Renal Physiology (AJP). Now, his ex-supervisor, Stuart Dryer, has pulled two more papers co-authored by the pair in Molecular Pharmacology.

Here’s the retraction notice for “Angiotensin II and Canonical Transient Receptor Potential-6 Activation Stimulate Release of a Signal Transducer and Activator of Transcription 3–Activating Factor from Mouse Podocytes:” Continue reading Researcher denied PhD after “recklessly” committing misconduct

A researcher sued critics of his work. Now he has 13 retractions.

A cancer researcher who sued PubPeer commenters for criticizing his work has lost six more papers, bringing his total to 13 retractions. 

Four of the new retraction notices issued by the journal Cancer cite an investigation at Wayne State University in Michigan into the work of Fazlul Sarkar and some of his colleagues. All the new notices, including the other two in Breast Cancer Research and Treatment, are for image-related issues.

Retraction Watch readers will recognize the name Fazlul Sarkar, who took PubPeer to court to unmask the anonymous critics whose comments cost him a job at the University of Mississippi. According to this document, Sarkar retired from Wayne State this year.  

Here’s the first of the four Cancer retraction notices, all of which were issued on July 29: Continue reading A researcher sued critics of his work. Now he has 13 retractions.

Researcher whose PhD was revoked is no longer at Harvard lab

mend.2016.30.issue-8.coverA research fellow at Harvard Medical School whose PhD was revoked last month is no longer working in his former lab, Retraction Watch has learned. 

An archived version of the lab site for Alfred Goldberg from December, 2015, lists Sudarsanareddy Lokireddy as a postdoctoral fellow; however, Goldberg’s current lab site doesn’t include Lokireddy as a lab member.

We contacted Goldberg’s lab, and he was unavailable for comment. We were told all of his lab members are on the current website.

Lokireddy has also logged his sixth retraction. But this case isn’t as straightforward as it seems.

Biotech journal pulls well-cited review that plagiarized from several sources

Applied Microbiology and BiotechnologyA biotechnology journal has retracted a 14-year-old review after an investigation concluded that the authors had plagiarized from numerous sources.  

The last author of the paper — which has been cited 289 times, according to Thomson Reuters Web of Science — told us the authors took a few lines from other reviews, and unintentionally left off the references.

In June 2011, the same author was denied a prestigious fellowship after an anonymous plagiarism allegation was filed against him. 

Here’s the retraction notice in Applied Microbiology and Biotechnology for “The nitrile-degrading enzymes: current status and future prospects:” Continue reading Biotech journal pulls well-cited review that plagiarized from several sources

Saudi institution didn’t clear genotyping study

Journal of Pharmacy and Pharmacology

A journal is retracting a paper that sought to validate genotyping techniques after learning the authors skipped a key step.

The authors scanned blood samples from 500 people who visited “the Blood Bank of our institution,” as they note in the abstract, to validate the use of genotyping techniques in the Saudi population. But the authors didn’t obtain the proper clearance from their institution, King Faisal Specialist Hospital, to publish the work.

Here’s the retraction notice for “Genotyping of CYP2C19 polymorphisms and its clinical validation in the ethnic Arab population:”

PhD student expelled for submitting paper without co-authors’ consent

PLOS OneA PhD student has been expelled from a university in China after publishing a paper in PLOS ONE without the permission of her co-authors, and using an external company to complete some of the work. 

PLOS ONE has now retracted the paper, noting that they were tipped off to the problems by a reader who raised concerns about some of the figures. The notice states that the study’s first author, Zhenni Zhang, takes full responsibility. 

The last author of the paper — Zongfang Li from the Xi’an Jiaotong University in China — told us Zhang was his PhD student who was close to completing her PhD, but has now been expelled.

Here’s the retraction notice, issued on July 25: Continue reading PhD student expelled for submitting paper without co-authors’ consent
