We have an update on a case we reported last week involving four papers in two different journals. The Journal of Bacteriology retracted two papers by Carlos Barreiro and colleagues, in notices that referred to the fact that
…identical bands for the 16S rRNA probe controls in the Northern blots were reported to correspond to experiments using different strains and experimental conditions in articles published in this journal and in Microbiology over a period of 5 years…
We checked with the editor of Microbiology, Agnes Fouet, who tells us: Read the rest of this entry »
The liver is the only internal organ that can regenerate. So perhaps it shouldn’t be surprising that Egyptian researchers tried to publish the same paper about liver ischemia twice in different journals. They succeeded — for a little while, at least.
The Journal of Molecular Histology is retracting the second of the articles to appear. Titled “Effect of preischemic treatment with fenofibrate, a peroxisome proliferator-activated receptor-α ligand, on hepatic ischemia–reperfusion injury in rats,” (which is still available online) it was published in 2011 by Vivian Boshra and Amal M. Moustafa of Mansoura University.
Trouble was, in 2011 Moustafa and Boshra, in that order, had also published “Effect of fenofibrate on the experimentally induced hepatic ischemia/reperfusion injury in rats: biochemical, light, and electron microscopic studies” in the Egyptian Journal of Histology (link to pdf).
That, as we know, is not done.
Readers of this blog — and anyone who has been following the Anil Potti saga — know that MD Anderson Cancer Center was the source of initial concerns about the reproducibility of the studies Potti, and his supervisor, Joseph Nevins, were publishing in high profile journals. So the Houston institution has a rep for dealing in issues of data quality. (We can say that with a straight face even though one MD Anderson researcher, Bharat Aggarwal, has threatened to sue us for reporting on an institutional investigation into his work, and several corrections, withdrawals, and Expressions of Concern.)
We think, therefore, that it’s worth paying attention to a new study in PLOS ONE, “A Survey on Data Reproducibility in Cancer Research Provides Insights into Our Limited Ability to Translate Findings from the Laboratory to the Clinic,” by a group of MD Anderson researchers. They found that about half of scientists at the prominent cancer hospital report being unable to reproduce data in at least one previously published study. The number approaches 60% for faculty members: Read the rest of this entry »
The journal Scoliosis has retracted a 2012 paper by a pair of German spine doctors over what the editors have called a less-than-fully declared conflict of interest involving one of the authors.
That should be relatively straigtforward – but it’s not quite. Turns out the article does include a disclosure, although perhaps the information it contains was incomplete.
The article, “Soft braces in the treatment of Adolescent Idiopathic Scoliosis (AIS) – Review of the literature and description of a new approach,” was written by Hans-Rudolf Weiss and Mario Werkmenn. Weiss, it seems, has something of a pedigree in the field. According to this website, he practices the “Schroth method” of recurvature, a technique pioneered by his grandmother, Katharina Schroth. From the site: Read the rest of this entry »
Nanotech researcher SK Sahoo, whom as we reported in February lost four papers from Acta Biomaterialia for what the journal called “highly unethical practices,” has actually retracted five papers from that journal.
According to a notice for “Enhanced cellular uptake and in vivo pharmacokinetics of rapamycin loaded cubic phase nanoparticles for cancer therapy” that appears in the June issue along with the other four: Read the rest of this entry »
