Prominent NIH researcher up to a dozen retractions

with 10 comments

Neuroscientist Stanley Rapoport hasn’t had much luck with his co-authors.

Recently, we’ve reported on multiple retractions of papers co-authored by Rapoport after three different first authors were found to have committed misconduct. Now, the fallout from one of those cases had led to four more retractions, bringing Rapoport’s total to 12.

The latest batch of retractions stem from the actions of Jagadeesh Rao.

Here’s the first notice, issued by Psychopharmacology:

Lost your data? Blame an earthquake

with 7 comments

A natural disaster is to blame for a retraction about lethal brain tumors. At least, that’s where the authors say the problem started: with a 2010 earthquake that caused a loss of “substantial data.”

The paper, “Superoxide-dependent uptake of vitamin C in human glioma cells,” looks at how the cells of lethal brain tumors interact with the vitamin commonly used to reduce side effects of therapies.

Post earthquake, someone digitally filled in a western blot analysis of proteins from a cell line and rat brains, as a “temporary solution.” And then the temporary solution made its way into the Journal of Neurochemistry.

Here’s the retraction note from the journal, including an image of the sneaky western blot:

Cut and paste and a PC crash: figure manipulations sink two papers

with 4 comments

Two papers by an overlapping group of researchers in Italy have been retracted for manipulated figures.

In late 2013, perennial tipster Clare Francis sent their concerns about several papers, including the two that have been retracted, by authors who frequently publish together. One of the papers, in the Journal of Neurochemistry, is from a team led by Ferdinando Nicoletti; four other papers from the group have been criticized on PubPeer for image manipulation, which he addressed via email with us.

The second retracted paper, from the Journal of Immunology, has shares one author with the first: Patrizia Di Iorio of the University of Chieti, though according to Nicoletti she had no role in preparing the figures.

Here’s the April 2014 notice for “Neuroprotection mediated by glial group-II metabotropic glutamate receptors requires the activation of the MAP kinase and the phosphatidylinositol-3-kinase pathways” in the Journal of Neurochemistry. It’s behind a paywall, but the journal has assured us this is against policy and they will be fixing it shortly:

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

with 6 comments

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: Read the rest of this entry »

And then there were eight: Three more retractions for Alirio Melendez, all in the Journal of Immunology

without comments

alirio_melendezAlirio Melendez, who has already retracted five papers and was found by one of his former universities to have committed misconduct on more than 20, has three more retractions.

Here’s the notice for “Antisense Knockdown of Sphingosine Kinase 1 in Human Macrophages Inhibits C5a Receptor-Dependent Signal Transduction, Ca2+ Signals, Enzyme Release, Cytokine Production, and Chemotaxis,” cited 68 times, according to Thomson Scientific’s Web of Knowledge: Read the rest of this entry »

Author whose duplications forced Cell correction retracts paper on Down syndrome

without comments

Sebastian Schuchmann, a neuroscience researcher whose duplication errors led to a Cell correction last year, has retracted a 12-year-old paper in the Journal of Neurochemistry whose figures were copied from two of his earlier papers.

Here’s the notice: Read the rest of this entry »

Neurochemistry journal retracts paper after earlier mega-correction for an author who’s no stranger to errata

without comments

The Journal of Neurochemistry has retracted a 2008 paper, “Toll-like receptor 3 contributes to spinal glial activation and tactile allodynia after nerve injury,” it had initially corrected — and how.

The correction, which appeared online in August 2010, was extensive: Read the rest of this entry »

Journal of Neurochemistry retracts paper after SUNY Upstate medical school finds evidence of fraud

with 16 comments

Following an investigation by the State University of New York (SUNY) Upstate into the work of one of its neuroscientists, the Journal of Neurochemistry has retracted a 2007 paper.

The retraction notice is quite clear about why the paper is being withdrawn: Read the rest of this entry »

Another retraction for Jatinder Ahluwalia, in Journal of Neurochemistry

with 3 comments

The Journal of Neurochemistry will retract a paper by Jatinder Ahluwalia, the scientist who recently left his post at the University of East London following an investigation into his work.

Ahluwalia was lead author of the 2003 paper, “Activation of capsaicin-sensitive primary sensory neurones induces anandamide production and release,” while earning his PhD at Imperial College London. It had already been the subject of a June 2010 correction. That correction blamed the paper’s problems on a typo:  Read the rest of this entry »
