A pair of expressions of concern in PLOS ONE over vet science papers

PLoS ONE has issued two Expressions of Concern on unrelated studies, each of which offers plenty to be concerned about — and not just about the research itself.

One is a casualty of our old friend,  Jesús Lemus, the Spanish veterinary scientist accused of fabricating his data.

The article, titled “The PHA-Skin Test Reflects Acquired T-Cell Mediated Immunocompetence in Birds,” was published in September 2008 and cited 61 times, according to Google Scholar.

Back in April, the publisher posted this comment to the paper: Continue reading A pair of expressions of concern in PLOS ONE over vet science papers

And then there were 28: Two more retractions for Diederik Stapel

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

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

Most retraction notices don’t involve research misconduct or flawed data: new study

October, apparently, is “studies of retractions month.” First there was a groundbreaking study in PNAS, then an NBER working paper, and yesterday PLoS Medicine alerted us to a paper their sister journal, PLoS ONE, published last week, “A Comprehensive Survey of Retracted Articles from the Scholarly Literature.”

The study, by Michael L. Grieneisen and Minghua Zhang, is comprehensive indeed, reaching further back into the literature than others we’ve seen, and also including more disciplines: Continue reading Most retraction notices don’t involve research misconduct or flawed data: new study

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

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:

Feeling sheepish: Another retraction for Lemus, of study of whether livestock can spread chlamydia to birds

Jesús A. Lemus, the Spanish veterinary researcher whose work has been the subject of a misconduct inquiry, has another retraction for his CV. It’s his third, according to our count.

The newest retraction is from PLoS ONE:

Correction for MD Anderson’s Bharat Aggarwal arches eyebrows for the right reasons

We’ve written about mega-corrections that allow scientists to retrace virtually all of their steps yet preserve their publications as supposedly legitimate. And we’ve seen plenty of corrections that allow authors to assert that their conclusions are correct when evidently important pieces of data are themselves unreliable.

Now comes a correction that seems to us to strike the right chords, given the fact that editors are to a large extent at the mercy of authors in these situations. Continue reading Correction for MD Anderson’s Bharat Aggarwal arches eyebrows for the right reasons

Walk (back) an Egyptian (vulture): Another paper by Spanish vet under scrutiny retracted

With apologies to the Bangles for this post’s title, we have another vulture-related retraction from Jesús A. Lemus, the Spanish veterinary researcher whose results have come into question.

This one involves a paper that appeared in PLoS ONE in 2009, titled “Susceptibility to Infection and Immune Response in Insular and Continental Populations of Egyptian Vulture: Implications for Conservation.”

According to the notice: Continue reading Walk (back) an Egyptian (vulture): Another paper by Spanish vet under scrutiny retracted

Final report on cardiology researcher Poldermans confirms claims of misconduct

Erasmus Medical Center in the Netherlands has released the final report on Don Poldermans, finding that the institution’s once-star cardiology researcher committed misconduct.

As Larry Husten of CardioBrief reports, Erasmus MC’s investigation included that Poldermans — perhaps best known for his work on beta-blockers — has admitted to acts of misconduct but not to fraud.

That’s not merely a distinction without a difference. Continue reading Final report on cardiology researcher Poldermans confirms claims of misconduct
