Nature is retracting a 2010 paper by a team from Princeton and Drexel on the workings of Plasmodium falciparum, which causes malaria in people. How that came about seems to have been a winding road.
The article — a research letter — titled “Branched tricarboxylic acid metabolism in Plasmodium falciparum,” came from the Princeton lab of Manuel Llinás. It purported to find that:
The article, “Determinants of project success among HIV/AIDS NGOs in Rakai, Uganda,” appeared in the International Journal of Health Planning and Management, a Wiley title. The author was Stevens Bechange, who was listed as being with the Uganda Virus Research Institute, in Entebbe. Bechange’s Linkedin page says he is a doctoral student at the University of East Anglia, in Norwich, UK, studying “Health, Wellness and Fitness.” His contact information on the article was an email with a CDC address (we’ve put in a call to the agency to find out more about his status but haven’t heard back yet).
As the abstract stated:
Last August, we reported on an Expression of Concern in the American Journal of Respiratory and Critical Care Medicine for a paper on HIV and lung injury. The notice said that the University of Nebraska, home to several of the paper’s authors, had begun an inquiry.
Today, the university issued a statement on the case, clearing the researchers of misconduct: Read the rest of this entry »
A group of Turkish researchers has had a paper retracted on how to treat the bacterium that cause ulcers after the journal’s editors found “issues related to the institutional review board approval” of the project.
In late December, we reported on the retraction of a 2010 research letter in Emerging Infectious Diseases looking at the genetics of swine flu.
The notice in the journal, a CDC publication, indicated that the conclusions were in error, although it didn’t really say much more:
To the Editor: We would like to retract the letter entitled “Triple Reassortant Swine Influenza A (H3N2) Virus in Waterfowl,” which was published the April 2010 issue of Emerging Infectious Diseases (1). The nucleoprotein gene sequences from the viruses reported in that letter are very closely related to those from the earliest detected triple reassortant swine influenza viruses [CY095676 A/sw/Texas/4199–2/1998(H3N2)]. Although these viruses could have acquired a swine-origin segment, the branch lengths are quite short for 9 years of evolution. Therefore, we have withdrawn these 4 isolates from GenBank and subsequently retract this letter.
As it happens, there was more to the story.
A team of Swiss microbiologists has retracted their 2012 paper in PLoS One on the genetics of the TB mycobacterium after learning that the fusion protein they thought they’d used in their study was in fact a different molecule.
Here’s the retraction notice for the article, “A β-lactamase based reporter system for ESX dependent protein translocation in mycobacteria,” which has been cited once, according to Thomson Scientific’s Web of Knowledge: Read the rest of this entry »
A new study in Clinical Chemistry paints an alarming picture of how often scientists deposit data that they’re supposed to — but perhaps not surprisingly, papers whose authors did submit such data scored higher on a quality scale than those whose authors didn’t deposit their data.
Ken Witwer, a pathobiologist at Hopkins, was concerned that a lot of studies involving microarray-based microRNA (miRNA) weren’t complying with Minimum Information About a Microarray Experiment (MIAME) standards supposedly required by journals. So he looked at 127 such papers published between July 2011 and April 2012 in journals including PLOS ONE, the Journal of Biological Chemistry, Blood, and Clinical Chemistry, assigning each one a quality score and checking whether the authors had followed guidelines.
A review paper published in the Serbian journal Medicinski pregled (Medical review) has been retracted for plagiarising a 2002 paper published in the Croatian Journal of Infection (or Infektološki glasnik).
The retraction note (in Serbian only) in the current issue (vol. 65, issue 11-12) of Medicinski pregled, published by the Society of Physicians of Vojvodina of the Medical Society of Serbia reads: Read the rest of this entry »
Partial retractions — as opposed corrections or the full monty — are unusual events in scientific publishing. But they appear to come in twos.
The article in question, by a group from the University of Kentucky in Lexington led by Susan Straley, appeared online in 2007. It was titled “yadBC of Yersinia pestis, a New Virulence Determinant for Bubonic Plague,” and, as the words suggest, involved a gene marker for the virulence of plague. Or so it initially seemed.
