A 2003 paper is now subject to an Expression of Concern after its author reused a lot of its material in a 2007 paper.
Here’s the Expression of Concern for “New therapeutic target in primary headaches – blocking the CGRP receptor” by Lars Edvinsson of the University of Copehagen: Continue reading Duplicate publication of headache paper earns Expression of Concern, erratum
BMC Genomics has issued an expression of concern for a 2011 paper by a prominent Argentine chemist, Ariel Fernandez, whose work covers several disciplines — “His research spans representation theory in algebra, physical chemistry, molecular biophysics, and more recently, molecular evolution and drug discovery” — and institutions. And therein lies the tale.
Fernandez appeared as the first author of the article, titled “Subfunctionalization reduces the fitness cost of gene duplication in humans by buffering dosage imbalances,” along with a pair of researchers from Taiwan. Fernandez’s affiliations were listed as being with the Instituto Argentino de Matemática “Alberto P. Calderón”, CONICET (National Research Council of Argentina), in Buenos Aires, the Department of Computer Science at the University of Chicago, and the Morgridge Institute for Research, in Madison, Wisc.
According to the abstract:

We have an update on two papers about lung cancer screening by Claudia Henschke and colleagues that were subject to an Expression of Concern early last year.
The original Expression of Concern in Cancer read, in part: Continue reading ORI, OHRP find “some human subject issues” in Henschke lung cancer studies, but no evidence of misconduct
A potential weight loss drug has been dealt what could be a serious setback after regulators found problems at two trial sites.
While awaiting a final report, The Lancet, which published a study of the drug, tesofensine, has issued an Expression of Concern: Continue reading Trial irregularities earn Lancet study of potential weight loss drug tesofensine Expression of Concern
PLOS ONE has issued a fascinating expression of concern about data collection in a paper it published late last year on the possible spread of deadly viruses among Indonesian orangutans. The case has been brought to the attention of the Indonesian government, but more on that in a moment.
The article, published last July by an international group of primate scientists led by Chairul Nidom, a virologist at Indonesia’s Airlangga University, sounded an alarm about “wild” orangutans in Borneo: Blood tests of 353 “healthy” animals showed antibodies for viruses akin to Ebola. What’s more, the filoviruses viruses to which the antibodies responded, as New Scientist and other outlets reported when the original paper came out, included strains not previously seen outside Africa (as well as Marburg, another deadly infection).
The article immediately prompted two comments. The first, by a poster called orangutanborneo, raised questions about the scale and logistics of the project: Continue reading Orangutan-Ebola link in PLOS ONE paper under scrutiny
A six year-old review on bird flu that failed to credit some content from another six year-old review of bird flu is now stamped with an Expression of Concern.
Here’s the notice, from Influenza and Other Respiratory Viruses: Continue reading Flu paper duplication earns Expression of Concern
The Journal of the American College of Cardiology, or JACC, has issued expressions of concern for three papers by Don Poldermans, the Dutch cardiologist who was fired earlier this year amid allegations of misconduct.
Cardiobrief’s Larry Husten had the story first.
The, um, heart of the matter is that neither the investigators at Erasmus Medical Center, Poldermans’ former institution, nor the JACC editors, can say whether the researchers conduct rose to the level of fabricating data. As the Notice of Concern states: Continue reading Concern — in triplicate — arrives for Poldermans papers
Diederik Stapel has three more retractions, making 31.
The most recent three we’ve found all appear in the European Journal of Social Psychology: Continue reading Diederik Stapel notches retractions 29, 30, and 31
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
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.
