Alejandra Bravo and Mario Soberon, a wife-husband research team at the National Autonomous University of Mexico (UNAM) who received sanctions — later lifted — for manipulating images in a number of papers have corrected another article.
The paper, “The mitogen-activated protein kinase p38 is involved in insect defense against Cry toxins from Bacillus thuringiensis,” appeared in Insect Biochemistry and Molecular Biology in 2010 and has been cited 23 times, according to Thomson Scientific’s Web of Knowledge. Here’s the correction notice: Read the rest of this entry »
PNAS has a curious correction in a recent issue. A group from Toronto and Mount Sinai in New York, it seems, had been rather too liberal in their use of text from a previously published paper by another researcher — what we might call plagiarism, in a less charitable mood.
To paraphrase Beyoncé: If you like it, better put some quotation marks around it. But we’re pretty sure she meant before, not after, the fact.
The article, “Structural basis for substrate specificity and catalysis of human histone acetyltransferase 1,” had appeared in May 2012, in other words, some 17 months ago. It has been cited twice, according to Thomson Scientific’s Web of Knowledge.
The Journal of Biological Chemistry has a fairly gory correction — we’d call it a mega-correction — for a 2010 paper by Levon Khachigian, an Australian researcher whose studies of a new drug for skin cancer recently were halted over concerns about possible misconduct, including image manipulation. As we reported earlier this year, Khachigian has already lost four papers, including one in the JBC — which the journal simply noted had “been withdrawn by the authors.”
The new correction involves the article “c-Jun regulates shear- and injury-inducible Egr-1 expression, vein graft stenosis after autologous end-to-side transplantation in rabbits, and intimal hyperplasia in human saphenous veins,” which Khachigian wrote with Jun Ni and Alla Waldman. The paper has been cited nine times, according to Thomson Scientific’s Web of Knowledge. Here’s the notice: Read the rest of this entry »
Ariel Fernandez, an Argentine chemist (who claims to hold the fastest-awarded PhD from Yale) and the subject of institutional investigations at multiple universities, has corrected several papers recently. What makes the moves particularly unusual — and interesting — is the stated reason for the amendments: disclaiming any funding from the National Institutes of Health for the work.
Fernandez was the recipient in 2005 of a $275,880 award “Protein packing defects as functional markers and drug targets.” The following year he received $294,217, and in 2007, $284,461, for the same four-year project, if we’re reading the link correctly.
Fernandez, readers of this blog might recall, threatened us with legal action when we wrote last spring about an expression of concern regarding his 2011 paper in BMC Genomics, “Subfunctionalization reduces the fitness cost of gene duplication in humans by buffering dosage imbalances.” According to that notice: Read the rest of this entry »
Last week, we reported on a new paper by Scripps Research Institute researchers in which they described how two of their previous papers had been based on mistaken interpretations. The authors wrote in their new paper that they were retracting the earlier works, but the journal had told them the papers would be corrected instead.
A group of animal health researchers from the Chinese Academy of Agricultural Sciences have lost their 2009 paper in the Journal of Microbiology and Biotechnology because they’d published the data in at least four other articles.
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 Journal of Neuroscience has retracted a 2012 paper by a group from Sweden’s Karolinska Institutet for what appears to be research misconduct. But more on that in a moment.
The article, “The Existence of FGFR1-5-HT1A Receptor Heterocomplexes in Midbrain 5-HT Neurons of the Rat: Relevance for Neuroplasticity,” came from the lab of Kjell Fuxe, whose interests include Parkinson’s disease, addiction and depression. The first and second authors, Dasiel Oscar Borroto-Escuela and Wilber Romero-Fernandez, are listed as being post-docs in the lab.
