Update: Data fabricator had masters’ degree revoked

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

Data fabrication fells muscle physiology paper

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.

Lemus, Stapel each rack up another retraction

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

Loose lips sink paper on company’s experimental pain drug

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.

Gastro journal continues tough stance on duplication, with two new retractions

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

ORI investigating University of Florida ob-gyn researcher accused of misconduct

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

Jumbled analysis leads to retraction of cancer study — but also another paper

The authors of a study on cancer incidence and survival in the Dutch migrant community have retracted it after realizing they’d made some errors that significantly affected the results.

But in what seems like an appropriate reward for coming forward, the newly analyzed data, with additional information, will be part of a forthcoming paper in another journal by the same authors.

The original retrospective study came out in May 2011 in the European Journal of Cancer Prevention and found that risk and survival of breast and stomach cancers differed depending on the person’s mother country. The problem was that the study jumbled up many of the participants’ homelands during the analysis.

The authors issued the following retraction: Continue reading Jumbled analysis leads to retraction of cancer study — but also another paper

HIV paper retracted after authors recommend a colleague as a reviewer

Nothing like a little home cooking.

Genetic Vaccines and Therapy (GVT) has retracted a paper by a group of Pakistani authors who recommended one of their colleagues as a reviewer for their manuscript.

That’s not all: According to the journal, the researchers apparently also misappropriated data from a previous study.

The article in question, “Structure based sequence analysis & epitope prediction of gp41 HIV1 envelope glycoprotein isolated in Pakistan,” was published in June 2012. The first author is  Syyada Samra Jafri, who we see as being at the University of the Punjab in Lahore. According to the retraction notice: Continue reading HIV paper retracted after authors recommend a colleague as a reviewer
