Two patch-clamping retractions in PNAS and the JCI after first author admits image manipulation

jci1212A group of cardiology researchers formerly of the University of Cologne has retracted two papers, after investigations into allegations of misconduct led to an admission of guilt by one of the lab’s junior members.

Here’s the first retraction, for “Connexin 43 acts as a cytoprotective mediator of signal transduction by stimulating mitochondrial KATP channels in mouse cardiomyocytes,” published last week in the Journal of Clinical Investigation: Continue reading Two patch-clamping retractions in PNAS and the JCI after first author admits image manipulation

Serial plagiarists earn lifetime publishing ban from Saudi journal

saudimedicineIn April, we wrote about a group of cancer researchers from Tunisia:

The M.O. of the group…appears to be quite simple: Find a study that looks easy to “replicate,” change a few of the particulars and submit as if it were a piece of local, original work.

One of the papers we cited in that post for appearing to be heavily plagiarized has now been retracted, with a heavy penalty for the authors. Here’s the notice, from the Annals of Saudi Medicine:  Continue reading Serial plagiarists earn lifetime publishing ban from Saudi journal

“Serious errors” in figures prompt concerning Neuroscience retraction

neuroscience1212 coverNeuroscience has retracted a 2009 paper by a team of Korean sports researchers for what appear to be figure irregularities. But the journal’s handling of the case is puzzling and unhelpful.

The article, “Treadmill exercise improves cognitive function and facilitates nerve growth factor signaling by activating mitogen-activated protein kinase/extracellular signal-regulated kinase1/2 in the streptozotocin-induced diabetic rat hippocampus,” came out of Korea National Sport University, among others. It seemed to suggest that exercise could make diabetic rats smarter.

According to the retraction notice: Continue reading “Serious errors” in figures prompt concerning Neuroscience retraction

Irritation turns to aggravation in Neuroscience correction

neuroscience1212 coverNeuroscience has an amusing correction in one of its December issues, involving a paper that appeared in its November 2011 issue on Parkinson’s disease by a group from Germany.

As the notice explains: Continue reading Irritation turns to aggravation in Neuroscience correction

Environmental engineer loses paper after co-authors say he didn’t have permission to publish it

j chem tech biotechAn environmental engineer at Israel’s Ben-Gurion University has been forced to retract a paper amid an ethics committee investigation into whether he had the right to publish it.

The Journal of Chemical Technology and Biotechnology retracted a study from the Vitaly Gitis lab just months after its publication: Continue reading Environmental engineer loses paper after co-authors say he didn’t have permission to publish it

Math paper retracted because some of it makes “no sense mathematically”

appmathlett

What do you do when a math paper that contains some “constructions and arguments [that] make no sense mathematically” gets published?

If you’re Applied Mathematics Letters, you retract the paper, “For the origin of new geometry.” Here’s the notice: Continue reading Math paper retracted because some of it makes “no sense mathematically”

“Additionally, the authors were unable to identify” co-author: Another retraction for Lemus

env microWe’ve been following the case of Jesús A. Lemus, the Spanish veterinary researcher with five retractions and two expressions of concern under his belt so far for suspected data fabrication and including a fake author on his papers.

Yes, a fake author. When this story first broke, El Pais called Javier Grande a ” ghost with a good academic background with at least six scientific publications in international journals.”

Grande’s — and Lemus’s — publication count declined by one more yesterday, as Environmental Microbiology retracted a 2007 paper: Continue reading “Additionally, the authors were unable to identify” co-author: Another retraction for Lemus

A new record: A retraction, 27 years later

jsbmbIn October, we noted the apparent record holder for longest time between publication and retraction: 25 years, for “Retention of the 4-pro-R hydrogen atom of mevalonate at C-2,2′ of bacterioruberin in Halobacterium halobium,” published in the Biochemical Journal in 1980 and retracted in 2005. (Although an author requested that another 52-year-old paper be retracted, it remains untouched in the literature.)

That record has now been broken. Congratulations to the Journal of Steroid Biochemistry and Molecular Biology and the authors of a December 1985 paper, “Increasing the response rate to cytotoxic chemotherapy by endocrine means.” Here’s the notice, which appears in the January 2013 issue of the journal, making 27 years — and a month, if you’re counting: Continue reading A new record: A retraction, 27 years later

“This publication should be ignored”: Authorship issues, flawed data fell neuro-oncology paper

Neon 2009 regular volume.inddThe Journal of Neuro-Oncology wants you to ignore the following paper: “A single chain (scFv425):sTRAIL fusion protein with specificity for the EGF receptor is effective in vitro but not in an in vivo brain tumor animal model.”

The 2007 article, from a group in The Netherlands, suffered from two fatal problems. According to the retraction notice: Continue reading “This publication should be ignored”: Authorship issues, flawed data fell neuro-oncology paper

Which came first? Plagiarism flap forces retraction of chicken nugget paper

food chem coverIt never pays to take a closer look at the inside of a chicken nugget.

The journal Food Chemistry has retracted a 2010 article by Iranian researchers who claimed to have used spectroscopy to examine the inner workings of breaded-fried chicken nuggets. Trouble was, someone else had already done the work.

Issues with the paper first surfaced in March, in the form of a correction that should have given the editors serious indigestion: Continue reading Which came first? Plagiarism flap forces retraction of chicken nugget paper
