Sir, that’s not my colon: Journal has a bite of a chicken and egg problem

Case report: An 85-year-old man eats some chicken and unknowingly swallows a bone. After two days of worsening abdominal pain, he shows up to the emergency room. A CT scan reveals the bone perforating his colon. He is rushed to surgery, which is successful. Then, during his otherwise uneventful recovery, he develops female breasts.

That’s not exactly the case report that showed up in the International Journal of Surgical Case Reports earlier this month, but then again, the images in the relevant case report aren’t exactly of someone’s colon, either.

With a warning that the clinical images below are mildly NSFW, here’s Figure 1 from the cleverly titled “Chicken or the leg: Sigmoid colon perforation by ingested poultry fibula proximal to an occult malignancy:” Continue reading Sir, that’s not my colon: Journal has a bite of a chicken and egg problem

Retraction appears for Harvard scientist who had two mega-corrections last year

molecular cellSam Lee, a Harvard biologist who had two mega-corrections published last year, has retracted a paper in Molecular Cell because some of the figures were “inappropriately assembled.”

Here’s the notice for “GAMT, a p53-Inducible Modulator of Apoptosis, Is Critical for the Adaptive Response to Nutrient Stress:” Continue reading Retraction appears for Harvard scientist who had two mega-corrections last year

Irony alert: Authors lose paper in loss prevention journal for plagiarism

losspreventionIf it seems that we write “irony alert” often, well, can you blame us? The Journal of Loss Prevention in the Process Industries (we’ll call it JLPPI for short) has retracted a paper it published earlier this year for plagiarism from multiple sources.

The article, “FTA vs. Tripod-Beta, which seems better for the analysis of major accidents in process industries?” was written by two occupational health researchers at Hamadan University of Medical Sciences in Iran. According to the abstract:

Paper retracted because images “were, in fact, electron microscopy results of totally different catalysts”

catcommA group of chemical engineers in China has retracted their article on photocatalysts after alerting the journal that images in the paper did not show what they’d reported.

The article, which appeared in Catalysis Communications earlier this year, was titled “Synthesis and characterization of novel Cu2O/PANI composite photocatalysts with enhanced photocatalytic activity and stability,” and was written by Xiufang Wang, Guangmei Chen and Jun Zhang of the School of Materials and Chemical Engineering at Anhui University of Architecture, in Hefei.

Here’s the retraction notice: Continue reading Paper retracted because images “were, in fact, electron microscopy results of totally different catalysts”

Penkowa notches fourth retraction, in Experimental Neurology

exp neuroMilena Penkowa, the Danish neuroscientist who resigned from the University of Copenhagen in December 2010 amid suspicions of misconduct, has had another paper retracted.

The new retraction appears in Experimental Neurology. Here’s the notice for “M-CSF deficiency leads to reduced metallothioneins I and II expression and increased tissue damage in the brain stem after 6-aminonicotinamide treatment”: Continue reading Penkowa notches fourth retraction, in Experimental Neurology

That face rings a bell, but where have I published it before?

ieriprocediaIrony alert: If you’re going to write a paper about face recognition technology, well, do we really need to go on?

A group of researchers in Wuhan, China, evidently didn’t quite realize they were walking into a ridicule trap when they agreed to have their paper, “Face Recognition with Learning-based Descriptor,” published in IERI Procedia. The article appeared in 2012 and was part of an issue devote to that year’s International Conference on Future Computer Supported Education, which took place in Seoul.

And now comes this: Continue reading That face rings a bell, but where have I published it before?

Anticancer-fungus paper retracted because some of the results “may be inaccurate”

biomacroMaybe it was a case of hitting the “send” button a bit too soon, or maybe it was a spasm of seller’s remorse, but a group of Chinese researchers has retracted a paper they’d published preliminarily a few months earlier.

The paper, “Antitumor and immunomodulatory activity of a polysaccharide from fungus Coprinus comatus (Mull.:Fr.) Gray,” by a group from various institutions in Shaanxi, appeared in April on the website of International Journal of Biological Macromolecules (as what appears to have been an uncorrected proof). But that didn’t stick.

According to a retraction notice dated August 2nd: Continue reading Anticancer-fungus paper retracted because some of the results “may be inaccurate”

Neural Networks retracts rerun

neuralnetworksIrony alert: If you’re going to write articles about recurrent neural networks, make sure they don’t, well, recur.

The journal Neural Networks has retracted a 2012 paper by a group of researchers from Spain for publishing what amounted to a repeat of a 2011 article in a different but closely related journal. Scientific publishing, alas, is not like Hollywood, where remakes of movies and TV shows is not only acceptable, it seems to be the only flavor producers are willing to taste.

The article was titled “Hopf Bifurcation Stability in Hopfield Neural Networks” — Hopf, for those keeping score at home, is Eberhard Hopf, a famous (and politically controversial) mathematician and founder of something called ergodic theory — and it came from scientists at the University of La Laguna, in the Canary Islands.

According to the notice: Continue reading Neural Networks retracts rerun

Virtual reality researcher notches fifth retraction

techforcchangeA researcher who studies the use of virtual reality and other media and who has already had four retractions has retracted another paper.

The 2007 paper by Dong Hee Shin, then of Penn State University, appeared in Technological Forecasting and Social Change and was titled “Potential user factors driving adoption of IPTV. What are customers expecting from IPTV?” It has been cited 24 times, according to Thomson Scientific’s Web of Knowledge.
