Nearly six months after first expressing concern about the validity of a 2010 paper on multiple sclerosis, Nature Medicine has retracted the article for containing “erroneous” data — which in this case don’t seem to have existed, making them more fabricated than wrong.
The paper, “Crucial role of interleukin-7 in T helper type 17 survival and expansion in autoimmune disease,” came from a group led by Jingwu Zhang, who at the time ran GlaxoSmithKline’s Research and Development Center in Shanghai.
Last week, we reported on a retraction in the Journal of Analytical Atomic Spectrometry that left us a bit puzzled. The notice referred to a problem with “the way the data was presented,” but the authors told us this was just an error picked up in proofreading, somehow after the paper had been published online.
We now have much more of the story. The Royal Society of Chemistry’s May Copsey, who edits the journal, tells Retraction Watch: Read the rest of this entry »
mBio, whose editor, Arturo Casadevall, has contributed greatly to our knowledge about why articles are retracted, has an interesting retraction of its own.
The journal — a publication of the American Society for Microbiology and the American Academy of Microbiology — is pulling a 2011 paper by a trio of researchers from the University of Alabama, Birmingham, Li Tan, Mei Li and Charles L. Turnbough Jr. The article was titled “An Unusual Mechanism of Isopeptide Bond Formation Attaches the Collagenlike Glycoprotein BclA to the Exosporium of Bacillus anthracis.” The paper, which has been cited twice, according to Thomson Scientific’s Web Knowledge, purported to show that:
In July, we reported on the unfortunate math of Harish Hosalkar, a San Diego orthopedic surgeon who was at the center of an institutional investigation into the integrity of his data, two lawsuits and three retractions.
At the time, we were waiting on the third retraction, in the journal Orthopedic Reviews. It has now arrived.
The article was titled “Open reduction and internal fixation of displaced clavicle fractures in adolescents,” and Hosalkar wrote it with Gaurav Parikh, James D. Bomar and Bernd Bittersohl. Read the rest of this entry »
But one group of scientists made hummus out of their approach when they botched what evidently was a key element of a figure in their 2011 paper in Plant Cell Reports (PCR).
The article, “High-efficiency Agrobacterium-mediated transformation of chickpea (Cicer arietinum L.) and regeneration of insect-resistant transgenic plants,” came from researchers at the National Botanical Research Institute in Lucknow, India. Cited three times, according to Thomson Scientific’s Web of Knowledge, it purported to find that: Read the rest of this entry »
Three retractions, two lawsuits, one institutional inquiry. That’s not the kind of math anyone likes to do — but it’s the tally for Harish Hosalkar, a San Diego surgeon specializing in pediatric orthopedics.
Hosalkar became embroiled in a messy affair after problems surfaced in data he had published while at Rady Children’s Hospital — a facility he left under a cloud of recriminations. More on that in a bit. Read the rest of this entry »
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 »
