A model retraction in the Journal of Neurochemistry for “unexpected effect” of a filter

jneurochemThey say that a poor workman blames his tools. If you’re a scientist and you discover your tools don’t do exactly what you thought they did, however, the right thing to do is let other scientists relying on your work know.

That’s what the University of Auckland’s Nigel Birch and colleagues did recently, after a 2012 study they published in the Journal of Neurochemistry didn’t hold up. Here’s the notice, which we’d consider a model for retractions everywhere: Continue reading A model retraction in the Journal of Neurochemistry for “unexpected effect” of a filter

Mitochondrial fission paper falls for fusing data from earlier work

brain research coverA team of neuroscientists in Japan has lost their 2012 article in Brain Research for duplicating elements of a figure from a paper they’d published earlier that year in another journal.

The article, “Dynamic changes of mitochondrial fission proteins after transient cerebral ischemia in mice,” came from a lab at Okayama University. The last author was Koji Abe. According to the retraction notice:

Duplicate publication of headache paper earns Expression of Concern, erratum

eottA 2003 paper is now subject to an Expression of Concern after its author reused a lot of its material in a 2007 paper.

Here’s the Expression of Concern for “New therapeutic target in primary headaches – blocking the CGRP receptor” by Lars Edvinsson of the University of Copehagen: Continue reading Duplicate publication of headache paper earns Expression of Concern, erratum

“Conflicting investigations” prompt expression of concern in BMC Genomics

BMC Genomics has issued an expression of concern for a 2011 paper by a prominent Argentine chemist, Ariel Fernandez, whose work covers several disciplines — “His research spans representation theory in algebra, physical chemistry, molecular biophysics, and more recently, molecular evolution and drug discovery” — and institutions. And therein lies the tale.

Fernandez appeared as the first author of the article, titled “Subfunctionalization reduces the fitness cost of gene duplication in humans by buffering dosage imbalances,” along with a pair of researchers from Taiwan. Fernandez’s affiliations were listed as being with the Instituto Argentino de Matemática “Alberto P. Calderón”, CONICET (National Research Council of Argentina), in Buenos Aires, the Department of Computer Science at the University of Chicago, and the Morgridge Institute for Research, in Madison, Wisc.

According to the abstract:

Eric Smart, the former University of Kentucky researcher found by the Office of Research Integrity to have faked images in ten papers, has two more retractions, both in the American Journal of Physiology — Cell Physiology.

Here’s one, for a paper cited four times, according to Thomson Scientific’s Web of Knowledge: Continue reading Two more Eric Smart retractions appear

ORI rules in longstanding University of Washington misconduct case

A case of alleged misconduct at the University of Washington in Seattle may finally be over. The Office of Research Integrity released its findings following an investigation into the work of Andrew Aprikyan, a former hematology researcher at the university.

The Aprikyan case has dragged on for a decade. In 2010, the university fired the scientist after a court denied his appeals based on allegations that they had denied him due process. As the Seattle Times reported at the time:  Continue reading ORI rules in longstanding University of Washington misconduct case

Second retraction appears for University of Wisconsin neuroscientist who faked images

brain researchA University of Wisconsin scientist who was found by the Office of Research Integrity (ORI) to have faked data in two papers, has had a second study retracted.

Here’s the notice: for “Secretory phospholipase A2 IIA is up-regulated by TNF-α and IL-1α/β after transient focal cerebral ischemia in rat,” by Rao Adibhatla and colleagues and originally published in Brain Research in February 2007: Continue reading Second retraction appears for University of Wisconsin neuroscientist who faked images

“Unsolved legal reasons” cause retraction of two biophysics papers

eur biophys jEvery now and then, we see retraction notices that refer vaguely to legal issues. Sometimes, we can dig up the actual reason. But the European Biophysics Journal has two retractions that leave us completely in the dark.

The two notices basically say the same thing. Here’s one: Continue reading “Unsolved legal reasons” cause retraction of two biophysics papers

Kenji Okajima retraction count grows to five

We’ve been following the case of Kenji Okajima, a professor at Nagoya City University in Japan who was suspended for six months following an investigation into work in his lab. Bits of the story — including at least one other university investigation, and scrutiny of Okajima’s colleagues, one of whom was fired — have been dribbling out for almost two years since a retraction notice in the Journal of Neuroscience.

In all, it looks as Nagoya found evidence of misconduct in 19 papers. The Journal of Neuroscience retraction appeared in 2011, and another showed up in the Journal of Immunology last year. Now there are three more: One in Translational Research and two in Blood.

Here’s the notice from Translational Research: Continue reading Kenji Okajima retraction count grows to five
