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

Immunology paper retracted because “documents were not archived with due diligence”

A group of researchers from Austria, Canada, Germany, and the U.S. have retracted a 2008 paper in the Journal of Immunology after being unable to verify the contents of some key figures.

The authors of a paper suggesting that cassava, a starchy vegetable that’s a major food source in much of the developing world, could one day be turned into a food staple “capable of supplying inexpensive, plant-based proteins for food, feed and industrial applications” have retracted it, following an institutional investigation that failed to find critical supporting data.

Here’s the notice for the PLoS ONE study, “Transgenic Biofortification of the Starchy Staple Cassava (Manihot esculenta) Generates a Novel Sink for Protein:” Continue reading PLoS ONE GMO cassava paper retracted after data “could not be found”

PLoS ONE expresses concern over flu vaccine paper

PLoS ONE has issued an expression of concern over a  2010 paper by Chinese scientists about how the immune system responds to the vaccine against the swine flu.

The article, “Protection Induced on Day 10 Following Administration of the 2009 A/H1N1 Pandemic Influenza Vaccine,” claimed to study 58 subjects given the inoculation (more on that below) and that Continue reading PLoS ONE expresses concern over flu vaccine paper

Spanish veterinary researcher under suspicion of creating “ghost” author, fabricating data

The Spanish press has picked up on the story of a prominent veterinary scientist in that country who has been accused of research misconduct.

According to El Pais, the researcher, Jesús Ángel Lemus, whose areas of interest include the effects of toxins on birds, ran into trouble in December when colleagues complained to the Ethics Committee of the Higher Council for Scientific Research about the reproducibility of his results and other problems. That triggered an inquiry by the CSIC into Lemus’ body of work, an investigation that, evidently, could not find a body.

Author who took responsibility for errors in retracted PNAS paper cites it…in error

via Wikimedia

One of the issues we’ve touched on at Retraction Watch is what happens once papers are retracted. A few studies have found that other authors continue to cite those studies anyway, without noting their withdrawal from the literature. A more recent paper found that retractions are linked to a dramatic decline in citations (see last half of post). And we’ve reported on one case in which the authors of a retracted study decided not to cite it at all when they republished their findings elsewhere.

But it seems unusual for an author to cite his or her own retracted work without noting it had been retracted. That’s what happened in a recently published PLoS ONE paper, “Loss of Secreted Frizzled-Related Protein 4 Correlates with an Aggressive Phenotype and Predicts Poor Outcome in Ovarian Cancer Patients.” The second to last paragraph of that paper ends: Continue reading Author who took responsibility for errors in retracted PNAS paper cites it…in error

PLoS One and Nature Medicine have issued corrections for papers by Zhiguo Wang, the former Montreal Heart Institute researcher who resigned in September following an investigation into image manipulation in his lab. 

In September, PLoS One told us that they were investigating the paper. Here’s the text of the correction for “Transcriptional and Post-Transcriptional Mechanisms for Oncogenic Overexpression of Ether À Go-Go K+ Channel:” Continue reading Corrections in PLoS One, Nature Medicine for Zhiguo Wang, and details about Montreal Heart Institute investigation

Concerns over language in PLoS One autism paper lead to brief withdrawal and correction

via Wikimedia

On September 28, PLoS One published a paper, “The Level and Nature of Autistic Intelligence II: What about Asperger Syndrome?”

But rather than celebrate another publication for her CV, one of the authors, Michelle Dawson, of Centre d’Excellence en Troubles Envahissants du Développement de l’Université de Montréal (CETEDUM) in Montréal, wasn’t happy. The PLoS One editors had made some changes she didn’t like. And she let everyone on Twitter know: Continue reading Concerns over language in PLoS One autism paper lead to brief withdrawal and correction

Potti retraction tally grows to six with a withdrawal in PLoS ONE, and will likely end up near a dozen

Anil Potti and his former Duke colleagues have retracted a sixth paper, this one in PLoS ONE.

According to the retraction notice for “An Integrated Approach to the Prediction of Chemotherapeutic Response in Patients with Breast Cancer,” the withdrawal was prompted by the retraction of a Nature Medicine paper that formed the basis of the PLoS ONE study’s approach: Continue reading Potti retraction tally grows to six with a withdrawal in PLoS ONE, and will likely end up near a dozen
