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.
Two different teams of physicists have retracted papers from Physical Review B after realizing that a sample used in the paper published first — and which formed the basis of the second paper — was mislabeled.
Here’s the notice for the first paper, “s-wave superconductivity in barium-doped phenanthrene as revealed by specific-heat measurements,” by Jianjun Ying of the University of Science and Technology of China, Hefei, and colleagues: Read the rest of this entry »
A group of cancer researchers in Japan has retracted their 2011 paper in the journal Medicine. The reason: They seem to have had some trouble — well, perhaps a bit more than some — with their patient population.
The paper’s no longer online, but we did find an abstract floating around: Read the rest of this entry »
A team of neuroscientists in Japan has lost their 2012 article in Brain Research for duplicating elements of a figure from a paper they’d published earlier that year in another journal.
The article, “Dynamic changes of mitochondrial fission proteins after transient cerebral ischemia in mice,” came from a lab at Okayama University. The last author was Koji Abe. According to the retraction notice:
We’ve been following the case of Kenji Okajima, a professor at Nagoya City University in Japan who was suspended for six months following an investigation into work in his lab. Bits of the story — including at least one other university investigation, and scrutiny of Okajima’s colleagues, one of whom was fired — have been dribbling out for almost two years since a retraction notice in the Journal of Neuroscience.
In all, it looks as Nagoya found evidence of misconduct in 19 papers. The Journal of Neuroscience retraction appeared in 2011, and another showed up in the Journal of Immunology last year. Now there are three more: One in Translational Research and two in Blood.
Hiroaki Matsubara, a leading Japanese cardiology researcher who has had three papers retracted and another five subject to expressions of concern, has resigned from Kyoto Prefectural University, according to local media.
Mainichi Shimbun reports — according to our roughest of (Google) translations — that Kyoto Prefectural University accepted Matsubara’s resignation following an investigation. That investigation — which the university had told us about last year — revealed serious problems with 27 studies.
There’s a new retraction in the journal Carbon.
The case didn’t involve a Carbon copy — say, plagiarism or duplication — but rather an instance of fraud in a Japanese university, part of a larger case we covered last August.
Here’s the retraction notice for the paper, “The role of Fe species in the pyrolysis of Fe phthalocyanine and phenolic resin for preparation of carbon-based cathode catalysts,” which appeared in August 2010: Read the rest of this entry »
As Larry Husten, who first reported the retraction at Forbes, notes, the notice for 2009′s “Effects of valsartan on morbidity and mortality in uncontrolled hypertensive patients with high cardiovascular risks: KYOTO HEART Study,” which appeared in the European Heart Journal, says very little: Read the rest of this entry »
An endocrinologist who resigned from the University of Tokyo last March as the university was investigating his work has retracted another paper.
