Achtentwintig.
That’s 28 in Dutch, and is the number of retractions so far racked up by Diederik Stapel, according to our count.
The latest two to come to our attention are in the British Journal of Social Psychology, where Stapel has already had a retraction.
Here’s one notice: Continue reading And then there were 28: Two more retractions for Diederik Stapel
PLOS ONE has retracted an article it published earlier this year by a group from Australia who failed to receive adequate ethics approval for their study.
The paper, “Late Complications of Clinical Clostridium Histolyticum Collagenase Use in Dupuytren’s Disease,” came from Warren M. Rozen, Yasith Edirisinghe and John Crock (sorry, irony machine not working today). Dupuytren’s causes thickening of the fascia in the hands and often requires surgery. In 2011 the FDA approved a treatment for the ailment that involves injections of an enzyme — Clostridium Histolyticum Collagenase, or CHC — into the affected area.
The Aussie article looked at the effects of CHC injections in 12 patients over one year, finding that two of the patients suffered Continue reading PLoS ONE retracts paper on treatment of tissue disease for lack of ethical approval, erroneous data
The International Journal of Hydrogen Energy has retracted a paper by a group from Malaysia and India who, reading between the lines, couldn’t quite get the low notes to overcome what the high notes lacked. Or something like that.
The paper, “Hydrogen production from sea water using waste aluminium and calcium oxide,” appears to have come out of the quaintly named 7th Petite Workshop on the Defect Chemical Nature of Energy Materials, held in March 2011 in Norway.
According to the notice: Continue reading Hydrogen study has “merit” — just not enough to avoid retraction
On Friday, we reported on the case of a retraction in the American Journal of Physiology — Cell Physiology by kinesiology researchers at Canada’s University of Waterloo for data fabrication by a graduate student, Sara Michelle Norris. We heard back from Waterloo yesterday, and have more details.
In our Friday post, we wondered whether Norris’s 2009 masters’ thesis,“Contribution of Sarcoplasmic Reticulum Calcium Pumping to Resting Mouse Muscle Metabolism,” might have been compromised. Waterloo tells us Norris is no longer at the university: Continue reading Update: Data fabricator had masters’ degree revoked
Kinesiology researchers at the University of Waterloo in Canada have been forced to retract a 2010 paper in the American Journal of Physiology — Cell Physiology in the wake of revelations that the first author, then a graduate student, fabricated her data.
The paper, “ATP consumption by sarcoplasmic reticulum Ca2+ pumps accounts for 50% of resting metabolic rate in mouse fast and slow twitch skeletal muscle,” was written by Sarah Michelle Norris and colleagues and published in March 2010.
According to the retraction notice: Continue reading Data fabrication fells muscle physiology paper
Pfizer has retracted a 2009 Journal of Clinical Oncology study purporting to show a benefit of their experimental drug for lung cancer figitumumab after discovering that its clinical lead on the project had done analyses improperly.
Here’s the text of the notice: Continue reading Pfizer retracts study of experimental cancer treatment figitumumab for incorrect analyses
The retraction counts keep mounting for two Retraction Watch frequent flyers.
First, Diederik Stapel’s 26th retraction, according to our count. Psychologist Stapel admitted to making up data in dozens of studies, and is also facing a criminal inquiry for misuse of funds.
Here’s the notice: Continue reading Lemus, Stapel each rack up another retraction
A bit of intellectual property indiscretion has led to the retraction of a paper by Korean scientists. Although the details are fuzzy, several of the authors are affiliated with a Korean pharma company called SK.
The paper, “A Novel Carbamoyloxy Arylalkanoyl Arylpiperazine Compound (SKL-NP) Inhibits Hyperpolarization-Activated Cyclic Nucleotide-Gated (HCN) Channel Currents in Rat Dorsal Root Ganglion Neurons,” was published in the The Korean Journal of Physiology & Pharmacology earlier this year.

Monica Acalovschi is serious about ridding the literature of duplicate publications.
That would seem to be the message of two new retraction notices in the Journal of Gastrointestinal and Liver Diseases, which Acalovschi edits — two retractions that join another for similar reasons, which we covered earlier this year.
Here are the notices, from the June issue of the journal (but which were just indexed by Medline):
For “Intestinal Pseudo-obstruction – a Rare Condition with Heterogeneous Etiology and Unpredictable Outcome. A Case Report:” Continue reading Gastro journal continues tough stance on duplication, with two new retractions
A prominent researcher at the University of Florida is under federal investigation for research misconduct and has lost at least one paper as a result of the fraud.
The researcher, Nasser Chegini, was a professor of obstetrics and gynecology at the U of Florida until about six months ago, when he retired, according to the chair’s office. Nasser has received at least $4 million in federal grant funding, according to the university.
The retracted paper, “MicroRNA 21: response to hormonal therapies and regulatory function in leiomyoma, transformed leiomyoma and leiomyosarcoma cells,” was published in 2010 by Molecular Human Reproduction. The authors were Qun Pan and Xiaoping Luo and Chegini.
As the notice explains: Continue reading ORI investigating University of Florida ob-gyn researcher accused of misconduct
