The two notices, for “Prediction of cardiovascular events in statin-treated patients by lipid and non-lipid biomarkers” and “Plasma PCSK9 levels and clinical outcomes in the TNT (Treating to New Targets) Trial,” are highly detailed and say the same thing: Read the rest of this entry »
Editor on retraction details: “I do not think this is the business of anyone but our journal, please”
Our readers will no doubt know by now that we think they’re basically everyone’s — at least if journals want us to believe that they’re interested in maintaining the integrity of the scientific record. But not all editors seem to agree. Hank Edmunds, for example, didn’t in early 2011, telling us, “It’s none of your damn business.” A chemistry journal editor said, in a similar vein, “the purpose of keeping these retraction notices slim is not to produce too much detail.”
A group of nutrition researchers at the University of California, Davis has retracted their paper in the International Journal of Molecular Sciences for what they describe as a botched experiment involving mixed-up cultures.
The article, titled “Dextran Sulfate Sodium Inhibits Alanine Synthesis in Caco-2 Cells,” appeared in 2011 and was retracted in February 2012, although it just came to our attention.
According to the abstract:
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.
A group of researchers from Mexico has been forced to retract their July 2012 paper in the International Journal of Radiation Oncology *Biology*Physics after a reader noticed cracks in the data that proved to be signs of fatal instability.
A researcher at the University of Ruhuna in Sri Lanka has been forced to retract a paper in the International Journal of Public Administration after evidently failing to properly install the computer software used to process the data.
The study, a letter titled “Triple Reassortant Swine Influenza A (H3N2) Virus in Waterfowl,” claimed to shed new light on how flu viruses might jump between species: Read the rest of this entry »
A group of smoking researchers — no, not scientists who are on fire; scientists who study the effects of tobacco smoke — has retracted a 2009 article after deciding that they were no longer “satisfied with the quality of the data.”
The paper, “Cigarette Smoke–induced Oxidative/Nitrosative Stress Impairs VEGF- and Fluid Shear Stress–Mediated Signaling in Endothelial Cells,” came from the lab of Irfan Rahman, a lung disease expert at the University of Rochester. It appeared online in 2009 in Antioxidants & Redox Signaling, which will be familiar to readers watching the case of Dipak Das.
The journal Environmental Entomology (that’s insects, not words) is retracting a 2010 paper on a sugarcane-loving borer insect by a group from south Florida.
The article, “Life Table Studies of Elasmopalpus lignosellus (Lepidoptera: Pyralidae) on Sugarcane,” came from the Everglades Research & Education Center, an arm of the University of Florida.
