Double-dipping leads to removal of petroleum research paper

pst journalcoverIranian scientists have lost one of two articles they submitted — and published — simultaneously to different journals. Watch as confusion ensues.

The retracted paper, “Permeability Estimation of a Reservoir Based on Neural Networks Coupled with Genetic Algorithms,” appeared online in August 2011  in Petroleum Science and Technology, a Taylor & Francis journal. According to the liner notes, the paper had been received on January 15, 2010 and accepted a few weeks later. It has been cited once since, according to Thomson Scientific’s Web of Knowledge, by its authors, in a paper published in the same journal.

Meanwhile, in August 2011 the authors (minus one name) also published “Evolving neural network using real coded genetic algorithm for permeability estimation of the reservoir,”  in Expert Systems With Applications, an Elsevier title.

The standing paper — which has been cited seven times — now carries the following erratum notice (dated far into the future, September 2013): Continue reading Double-dipping leads to removal of petroleum research paper

Plagiarism: It’s just an “approach” to writing papers, right?

chemistry coverWe’ve heard a lot of rationalizations for plagiarism on this beat — “I didn’t know I had to cite that text”; “That author said it better than I ever could”; etc. — but here’s a new one for the wall of shame.

Chemistry – A European Journal is retracting a 2012 article, “A New Indicator for Potassium Ions at Physiological pH by Using a Macrocyclic Luminescent Metal Complex,”  by a group of Chinese authors who used the cut-and-paste method to put together their manuscript. That’s not unusual. But the notice is:

Retraction for image issues forces correction of herbal remedies editorial

jmm mayBack in March, we wrote about the case of Chinese researchers who pulled their 2011 paper in the Journal of Molecular Medicine on ginseng’s potential as a heart remedy because a couple of their images were suspect (duplicated was the word they’d used).

Turns out the journal suffered some collateral damage. JMM also has corrected a “Clinical Implications” article by a group of Canadian researchers about the defunct ginseng paper.

The article, “Use of ginseng to reduce post-myocardial adverse myocardial remodeling: applying scientific principles to the use of herbal therapies,”  appeared in the same issue as the original, but for some reason the correction notice appeared online only last week.

It states: Continue reading Retraction for image issues forces correction of herbal remedies editorial

Heart pulls sodium meta-analysis over duplicated, and now missing, data

heart cover may13The journal Heart has retracted a 2012 meta-analysis after learning that two of the six studies included in the review contained duplicated data.  Those studies, it so happens, were conducted by one of the co-authors.

The article, “Low sodium versus normal sodium diets in systolic heart failure: systematic review and meta-analysis,” came from an eclectic group of authors from the United States, Canada and Italy (the first author is listed as being at a Wegmans pharmacy in Ithaca, N.Y.). The paper, published online in August 2012, purported to find that: Continue reading Heart pulls sodium meta-analysis over duplicated, and now missing, data

One-too-many authors scuttles paper on mouse metabolism

reg pepcoverRegulatory Peptides is retracting a 2010 paper by a group of five authors in China and one in Texas — and the presence of that last one was the problem.

The article, “Erythropoietin as a possible mechanism for the effects of intermittent hypoxia on bodyweight, serum glucose and leptin in mice,” had as its last (dare we say, senior) author Susan T. Howard, a mycobacterium expert at the University of Texas Health Science Center in Tyler. Trouble was, Howard disavowed any role in the paper.

According to the retraction notice: Continue reading One-too-many authors scuttles paper on mouse metabolism

Authors retract CT scan-cancer paper, citing faulty data

medicine coverA 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 article, titled “Usefulness of systemic CT scanning in the detection of malignant lymphadenopathy,” came from the lab of Norio Komatsu, a hematologist at Juntendo University School of Medicine.

The paper’s no longer online, but we did find an abstract floating around: Continue reading Authors retract CT scan-cancer paper, citing faulty data

ORI finds former North Carolina company lab tech faked data in NIH grant

advanced liquid logicThe Office of Research Integrity has sanctioned a former technician at a North Carolina technology firm after concluding that the researcher fabricated data while working on a project funded by the National Institute of Allergy and Infectious Diseases.

The researcher, Matthew Poore, was a technician at Advanced Liquid Logic when he committed the misconduct, according to the report. While at North Carolina State University prior to his job at Advanced Liquid Logic, Poore published, by our count, 11 papers, one of which was cited more than 50 times, according to Thomson Scientific’s Web of Knowledge. The ORI report does not mention any of them.

Here’s what it does say: Continue reading ORI finds former North Carolina company lab tech faked data in NIH grant

Purloined dissertation on stroke ends in retraction for Iranian group

intjneursciThe International Journal of Neuroscience, an Informa Healthcare journal, has retracted a paper it published earlier this year after learning that the article was the doctoral work of another scientist — not listed among the authors — that had appeared previously in a Persian-language journal.

The retraction notice, admirably thorough, explains what happened with the paper:

Authors retract already-corrected Nature malaria paper

Nature is retracting a 2010 paper by a team from Princeton and Drexel on the workings of Plasmodium falciparum, which causes malaria in people. How that came about seems to have been a winding road.

The article — a research letter — titled “Branched tricarboxylic acid metabolism in Plasmodium falciparum,” came from the Princeton lab of Manuel Llinás. It purported to find that:

Mitochondrial fission paper falls for fusing data from earlier work

brain research coverA 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:
