Another correction appears for husband-wife team found to have manipulated images

insectAlejandra 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: Continue reading Another correction appears for husband-wife team found to have manipulated images

Correction by punctuation? PNAS fixes paper by putting quotes around plagiarized passages

PNAScover1113PNAS 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.

As the notice states: Continue reading Correction by punctuation? PNAS fixes paper by putting quotes around plagiarized passages

JBC issues correction for paper by Khachigian, who has had four others retracted

jbc1113The 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this year, Khachigian has already lost four papers, including one in the JBC — which the journal simply noted had “been withdrawn by the authors.”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: Continue reading JBC issues correction for paper by Khachigian, who has had four others retracted

A complicated case involving two microbiology researchers at the National Autonomous University of Mexico (UNAM) appears to have come to some conclusion.

In November of last year, we reported that Continue reading “Not exoneration”: University reverses sanctions on husband-wife team found to have manipulated images

Researcher who threatened Retraction Watch with lawsuit corrects funding source for several papers

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: Continue reading Researcher who threatened Retraction Watch with lawsuit corrects funding source for several papers

Ask Retraction Watch: Should these papers be retracted?

protein scienceLast 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.

We had asked Protein Science editor Brian Matthews for clarification, and he emailed us late last week:

Birds of a feather: Authors who play games with fowl data earn multiple retractions

jmicrobiotechA 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.

The paper, “Two Novel Duck Antibacterial Peptides, Avian β-Defensins 9 and 10, with Antimicrobial Activity,” reported that: Continue reading Birds of a feather: Authors who play games with fowl data earn multiple retractions

Three retractions, two lawsuits, one institutional inquiry for San Diego orthopedic surgeon

11832_5_2_OC.inddThree 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. Continue reading Three retractions, two lawsuits, one institutional inquiry for San Diego orthopedic surgeon

Duplication earns engineering paper a corrigendum rather than a retraction

kybernetesTwo authors in Turkey have had their paper subjected to a correction after it became clear that material was lifted heavily from two previous papers by one of the researchers.

The corrigendum reads: Continue reading Duplication earns engineering paper a corrigendum rather than a retraction

Journal of Neuroscience retracts plasticity paper for “substantial data misrepresentation”

jneuroscicoverThe 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.
