An endocrinologist who resigned from the University of Tokyo last March as the university was investigating his work has retracted another paper.
Here’s the notice for the paper by corresponding author Shigeaki Kato and colleagues in the Journal of Bone and Mineral Research: Continue reading Shigeaki Kato notches fifth retraction
Royal jelly — “the goo that sustains honeybees destined for royalty” and is touted dubiously for everything “from youthful skin to virility,” as Nature put it — is apparently a hot research topic. So when a Retraction Watch tipster sent us a corrigendum that seemed to have done something we hadn’t seen before — retract a single figure, without saying why — we figured we’d check it out.
Here’s the text of the corrigendum: Continue reading Royal jelly figure flushed: Author removes figure from 2002 paper
Keeping up with the various investigations into the activities of Yoshitaka Fujii — the assumed record holder for retractions by a single author, with 172 likely — can be a challenge. Between the journals pulling his papers and the institutions looking into his misconduct, it’s hard to keep everything straight.
But we have a new report, from a past employer, that makes for interesting reading and helps tie up some loose ends. The document is from Tsukuba University, where Fujii worked more than a decade ago when questions about the propriety of his findings first surfaced. Continue reading Retraction record broken, again: University report should up Fujii total to 183
The Circulation Journal, the official organ of the Japanese Circulation Society, is retracting two papers by Hiroaki Matsubara, lead researcher on the Kyoto Heart Study, for unreliable findings. Matsubara’s institution, Kyoto Prefectural University, confirmed to us last March that it was investigating the prominent cardiologist.
The work of Matsubara came into question last year when the American Heart Association issued an expression of concern for five papers the society published in its journals. Larry Husten, at Forbes/CardioBrief, reports today that the two retracted articles were “Effects of Valsartan on Cardiovascular Morbidity and Mortality in High-Risk Hypertensive Patients With New-Onset Diabetes Mellitus: Sub-Analysis of the KYOTO HEART Study,” published in September 2012; and “Enhanced cardiovascular protective effects of valsartan in high-risk hypertensive patients with left ventricular hypertrophy: Sub-analysis of the KYOTO HEART study,” which appeared in March 2011.
The retraction notice for the most recent paper states: Continue reading Journal retracts two papers by Japanese cardiologist under investigation
The Journal of Neuroscience has retracted a 2011 paper by an international group of scientists, including the prominent Maryland researcher Ronald Dubner, but readers won’t know why.
As the notice “explains“: Continue reading Journal of Neuroscience retraction, typically opaque, from author with history of errors
The journal System evidently needs a new one — at least when it comes to production.
The publication has been forced to retract an article that it published twice — in the same issue.
Here’s what happened: Continue reading Failure at System — systems failure? — leads to duplicate publication, retraction
It was, as Nature News wrote last month, a story that “seemed too good to be true:”
Stem-cell transplant claims debunked
Transplant of induced pluripotent stem cells to treat heart failure probably never happened
Hisashi Moriguchi, a visiting researcher at the University of Tokyo, had claimed a result that would have put him years ahead of researchers toiling in stem cell research. But the claims were met with a great deal of doubt — to say the least — and the story began to unravel when Harvard, where Moriguchi said he’d done the work, denied it had ever taken place.
And as expected, the retractions have now started. Today, a Nature Publishing Group journal said they would be retracting two papers, “A therapeutic method for the direct reprogramming of human liver cancer cells with only chemicals” and “Successful cryopreservation of human ovarian cortex tissues using supercooling.” The notices for the Scientific Reports papers will both say the same thing: Continue reading Two Moriguchi stem cell papers being retracted
A gynecologic cancer researcher at Oita University in Japan has retracted three papers by his group after the discovery of duplicated figures and manipulated images.
The three papers by Noriyuki Takai and colleagues all appeared in Gynecologic Oncology: Continue reading Three gynecologic cancer studies retracted for figure duplication, image manipulation
We’re not sure how many you need for a “slew,” but we’ve seen five retractions in Neuroscience Letters recently, most of them because researchers republished translations of papers in English, so we thought we’d round them up in a post.
We’ll start the count — appropriately, we think — with the notice for “Simple mental arithmetic is not so simple: An ERP study of the split and odd–even effects in mental arithmetic“, published in February by researchers from Nanjing Normal University in China: Continue reading Slew of retractions appears in Neuroscience Letters
Eighteen years ago, the Journal of Dermatology published an article, “A sulfated proteoglycan as a novel ligand for CD44,” by a group of Japanese researchers (the journal is the official periodical of the Japanese Dermatological Society).
The JoD is now retracting that paper because it overlaps with another article by the same group, published a few months earlier in a different journal.
Here’s the notice (behind a pay wall — tsk, tsk, Wiley): Continue reading Eighteen years later, derm journal retracts overlapping article, citing editorial error
