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.

Here’s the notice from Translational Research: Continue reading Kenji Okajima retraction count grows to five

Seals of disapproval, as pinniped paper gets yanked for plagiarism

ImageJoseph Hoffman, an animal behavior researcher at the University of Bielefeld in Germany says he got a “kind of odd” feeling as he read a recent paper on the transcriptome of the spotted seal. Let’s just call it deja vu.

The article, “Characterization of the spotted seal Phoca largha transcriptome using Illumina paired-end sequencing and development of SSR markers,” which appeared in Comparative Biochemistry and Physiology Part D: Genomics and Proteomics:

Post 982 — in which we find plagiarized bone graft paper that grafted from other papers

thesurgeonThe Surgeon has retracted a 2012 article by a group from the U.K. who took text from a previously published article. So, you say? Nu?

Well, we found — through relatively little effort — that the plagiarizees were themselves, shall we say, liberal in their use of material from other sources.

The retracted article was titled “Bone graft substitutes: What are the options?,” and it appeared in August 2012. One of the options, we guess, was to steal text.

According to the retraction notice: Continue reading Post 982 — in which we find plagiarized bone graft paper that grafted from other papers

The “unintentionality” of being leads to nothingness for paper on protein’s role in cancer

empcoverA group of cancer researchers in Argentina has retracted a paper on the p300 protein in breast cancer that appeared in Experimental and Molecular Pathology.

The article, titled “Intracellular distribution of p300 and its differential recruitment to aggresomes in breast cancer,” was published in 2010 by Maria E. Fermento and colleagues. It has been cited 11 times since, according to Thomson Scientific’s Web of Knowledge.

“Considerable overlap” leads to retraction of medical imaging paper

PRL cover313

We have poked fun at Pattern Recognition Letters before for failing to catch blatant plagiarism. We probably should have held off on those jokes for this post.

A group of IT researchers from India has suffered the retraction of a paper in PRL for heavily basing the piece on at least four previous papers written by one of the co-authors without proper attribution (not that such attribution likely would have absolved the sin).

The paper, titled “A robust kernelized intuitionistic fuzzy c-means clustering algorithm in segmentation of noisy medical images,” was published in January of this year by Prabhjot Kaur and colleagues.

Here’s the retraction notice:

Paper — with longest title ever? — retracted for lack of author approval

inorgchimactaThe journal Inorganica Chimica Acta has retracted a paper it published earlier this year over an authorship dispute involving the lead researcher and his colleagues in France.

The title of the paper — whose bulk alone gave us a headache  — was “Reaction of a bidentate ligands (4,4′-dimethyl 2,2′-bipyridine) with planar-chiral chloro-bridged ruthenium: Synthesis of cis-dicarbonyl[4,4′-dimethyl-2,2′-bipyridine- κO1,κO2]{2-[tricarbonyl(η6-phenylene- κC1)chromium]pyridine-κN}ruthenium hexafluorophosphate” — and it purportedly came from a lab in Beirut.

However, as the retraction notice indicates, that’s not quite so:

Study plagiarizes so many other papers, retraction notice can’t list them all

j controlled releaseIn a new retraction notice, the Journal of Controlled Release is living up to its name.

The editor-in-chief has retracted a study that plagiarized “a large number” of papers, but only three are listed in the notice. Here’s the notice for “In situ-forming hydrogels for sustained ophthalmic drug delivery,” by Basavaraj K. Nanjawade, F.V. Manvi, and A.S. Manjappa, three researchers at India’s KLES’s College of Pharmacy, JN Medical College Campus, Karnataka: Continue reading Study plagiarizes so many other papers, retraction notice can’t list them all
