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.

Authors dispute ethical lapse in case of double physics publication that wasn’t

Plasma Processes and Polymers has retracted a paper it published in March 2012 for what it describes as a “possible breach of ethics.”

That certainly sounds bad — if inconclusive — but the authors maintain the whole thing was a simple misunderstanding.

The article, “Plasma Acid: Water Treated by Dielectric Barrier Discharge,” came from the lab of Gary Friedman, a physicist at Drexel University in Philadelphia. The first, and corresponding, author was Natalie Shainsky, an award-winning graduate student at the school.

Bitter authorship issues prompt Expression of Concern in rheumatology journal

A difficult authorship dispute, involving two journals and at least two continents, has led to an Expression of Concern in the Brazilian Journal of Rheumatology.

Here’s the Expression of Concern: Continue reading Bitter authorship issues prompt Expression of Concern in rheumatology journal

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

Another odd retraction for alcohol researcher, this time for lack of animal research committee approval

The journal Neuroscience has retracted a 2011 paper by an alcohol researcher from the United Arab Emirates, who apparently conducted some mouse studies without the blessing of his institution’s animal ethics officials. At least, that’s what the retraction notice would have us believe.

The paper in question, “The pre-synaptic metabotropic glutamate receptor 7 “mGluR7” is a critical modulator of ethanol sensitivity in mice,” by Amine Bahi, was published in December 2011 and cited three times (twice by the author), according to Thomson Scientific’s Web of Knowledge. But as the notice explains:

Duplication forces retraction of paper on effects of prenatal environment on behavior

A journal has retracted a 2005 paper by a group of physiologists at the University of Toronto after it became clear that the work duplicated five other articles by the same researchers.

Here’s the notice in Neuroscience & Biobehavioral Reviews for “Maternal adversity, glucocorticoids and programming of neuroendocrine function and behaviour:” Continue reading Duplication forces retraction of paper on effects of prenatal environment on behavior

“Major errors” lead to retraction of Nature Photonics paper on quantum dots

Maybe it’s an occupational hazard of dealing with quantum physics — uncertainty and all that — but a group of Swiss researchers has retracted their paper on quantum dots after discovering “major errors” that undermined their conclusions.

The article, published in 2010 as a research letter in Nature Photonics, was titled “Polarization-entangled photons produced with high-symmetry site-controlled quantum dots,” by Eli Kapon and colleagues.

According to the retraction notice: Continue reading “Major errors” lead to retraction of Nature Photonics paper on quantum dots

High school whiz kid retracts PLoS ONE herd immunity paper

Georgette speaking at the Davidson Institute’s award ceremony, Library of Congress, 2008

It’s pretty impressive to publish two peer-reviewed papers on complicated vaccination models while you’re still in high school. So it’s not surprising that Nathan Georgette, who grew up outside of Jacksonville, Florida, earned a prestigious fellowship from the Davidson Institute for Talent Development.

But perhaps even more impressive is realizing you’ve made a fundamental error in one of those studies, and retracting it while you’re still a college senior at Harvard. Continue reading High school whiz kid retracts PLoS ONE herd immunity paper
