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Researcher whose PhD was revoked is no longer at Harvard lab

mend.2016.30.issue-8.coverA research fellow at Harvard Medical School whose PhD was revoked last month is no longer working in his former lab, Retraction Watch has learned. 

An archived version of the lab site for Alfred Goldberg from December, 2015, lists Sudarsanareddy Lokireddy as a postdoctoral fellow; however, Goldberg’s current lab site doesn’t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

Biochem journal retracts paper for “striking level of similarity” with another

Molecular and Cellular Biochemistry CoverA biochemistry journal has pulled a paper after deciding that its layout and content overlapped significantly with a previously published paper.

The researcher who reported the similarity to Molecular and Cellular Biochemistry has sent us his correspondence with the journal. After a “thorough investigation,” the journal felt the paper was worth retracting.

Here’s the retraction notice for “TNF receptor-associated factor 6 regulates proliferation, apoptosis, and invasion of glioma cells:” Continue reading Biochem journal retracts paper for “striking level of similarity” with another

Neuroscientist in Serbia earns 8th retraction amid investigation

RadenovicA neurobiologist has notched her eight retraction in the midst of an ongoing investigation into her work by her institution, the University of Belgrade in Serbia.

As we reported previously, a mass clean-up by the Archives of Biological Sciences (ABS), the official journal of the Serbian Biological Society resulted in six retractions of papers co-authored by Lidija Radenović. (Radenović served as vice president of the Serbian Biological Society until July 2014.)

In April, we reported that Radenović was about to notch her seventh retraction in Acta Neurologica Scandinavica; that paper has now been pulled, and ABS has retracted another one of her papers.

Here’s the retraction notice by ABS: Continue reading Neuroscientist in Serbia earns 8th retraction amid investigation

You’ve been dupe’d: Nice data — let’s see them again

As we’ve said before, with hundreds of retractions per year, there are simply too many for us to cover individually.

So from time to time we’ll compile a list of retractions that appeared relatively straightforward, just for record-keeping purposes.

Often, these seemingly straightforward retractions involve duplications, in which authors — accidentally or on purpose — republish their own work elsewhere.

Sometimes journals and authors blame this event on “poor communication,” our first example notes:

Four more retractions for biomaterials researcher brings total to 7

Journal of Controlled ReleaseA biomaterials researcher has lost four more papers for figure-related issues such as duplications, bringing his total to seven retractions.

We previously reported on three retractions — two by the Journal of Controlled Release (JCR) — of papers co-authored by Hossein Hosseinkhani, who is currently based at the National Taiwan University of Science and Technology in Taipei. Now, the JCR is pulling four more studies that list Hosseinkhani as a co-author.

Here’s the retraction notice for “Enhanced expression of plasmid dna – cationized gelatin complex by ultrasound in murine muscle:” Continue reading Four more retractions for biomaterials researcher brings total to 7
