The article, “Testosterone therapy improves psychological distress and health-related quality of life in Chinese men with symptomatic late-onset hypogonadism patients,” came from a group at Peking University People’s Hospital, in Beijing.
But as the retraction notice explains: Read the rest of this entry »
The journal Neuro-Oncology has retracted a 2011 paper by a group of researchers in Japan who had purported to find a genetic mechanism for how fluorescence can be used to diagnose certain brain tumors.
The paper, “Enhanced expression of coproporphyrinogen oxidase in malignant brain tumors: CPOX expression and 5-ALA–induced fluorescence,” reported measurements using quantitative real-time (qRT)-PCR.
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.
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 »
The journal Neurology has issued an Expression of Concern over recommendations it published earlier this year regarding the treatment of multiple sclerosis.
The journal’s website received multiple comments from clinicians expressing their own concern about the flawed recommendation, which was published as part of a paper titled “The American Academy of Neurology’s Top Five Choosing Wisely recommendations.” The problematic item was number 4: Read the rest of this entry »
No, not that Madoff.
We’re talking about Robert Madoff, editor of Diseases of the Colon & Rectum. His journal is pulling a 2012 paper by a group of authors in Spain who seem to have been unable to back up their findings when they were found to contain errors.
The article, “Perianal versus endoanal application of glyceryl trinitrate 0.4% ointment in the treatment of chronic anal fissure: results of a randomized controlled trial. Is this the solution to the headaches?” looked at what evidently is a significant side effect of nitroglycerin treatment for anal fissures: headaches. According to the abstract:
Here’s the retraction notice for “Slug enhances invasion ability of pancreatic cancer cells through upregulation of matrix metalloproteinase-9 and actin cytoskeleton remodeling,” by Liqun Wu and colleagues of The Affiliated Hospital of Medical College, QingDao University, in China’s Shan Dong Province: Read the rest of this entry »
Back in March, we wrote about the case of Chinese researchers who pulled their 2011 paper in the Journal of Molecular Medicine on ginseng’s potential as a heart remedy because a couple of their images were suspect (duplicated was the word they’d used).
Turns out the journal suffered some collateral damage. JMM also has corrected a “Clinical Implications” article by a group of Canadian researchers about the defunct ginseng paper.
The article, “Use of ginseng to reduce post-myocardial adverse myocardial remodeling: applying scientific principles to the use of herbal therapies,” appeared in the same issue as the original, but for some reason the correction notice appeared online only last week.
