Chem paper fails to catalyze when wrong files are “inadvertently used”

joceah_v080i008.inddThree chemists at the Indian Institute of Technology Guwahati in India have retracted a paper from the Journal of Organic Chemistry because the “incorrect files were inadvertently used.”

The article, “Room-Temperature Cu(II)-Catalyzed Chemo- and Regioselective Ortho-Nitration of Arenes via C–H Functionalization,” described a protocol to perform nitration — the addition of nitro groups onto an organic compound — using an inexpensive copper catalyst.

All three authors signed the one-sentence notice:

Reporting errors sink chem paper on liquid-liquid equilibrium

Jced_coverA team of chemists at Hunan University and Zhejiang Shuyang Chemical Company in China have retracted a paper from the Journal of Chemical & Engineering Data after “inconsistencies with the literature” led them to discover “errors” in the way the data were reported.

According to the corresponding author Qinbo Wang, in December 2014, Robert Chirico, an associate editor at the journal, contacted Wang with concerns that the paper’s data were an anomaly.

Wang then went through the original notes with the first author, and realized that the data reported in the paper didn’t match the experimental results. The lab then conducted further experiments, and discovered that multiple corrections would be necessary. They were, as Wang told us: Continue reading Reporting errors sink chem paper on liquid-liquid equilibrium

Snail egg article retracted for fishing for material from six other papers

APJTB_ak1The first author of a review article on extracting pharmacological compounds from marine organisms, published in the Asian Pacific Journal of Tropical Biomedicine, has retracted it due to plagiarism.

There were also some authorship issues, according to the retraction notice for the paper, which absolves the last author, based at Pondicherry University in India, from responsibility:

This article has been retracted at the request of the Editor-in-Chief and the First Author. Both the first author and the journal’s editor confirmed that Dr. A Yogamoorthi is not responsible for the plagiarism since his/her name was added without consent.

There is one other author, R. Siva Sankar, also based at Pondicherry. Somewhere along the way, according to the retraction note, the paper scooped up wording from six papers previously published by researchers in Australia. Here’s more from the retraction note for “Antimicrobial secondary metabolites from marine gastropod egg capsules and egg masses”: Continue reading Snail egg article retracted for fishing for material from six other papers

Chinese medical case study erased after guardian consent withdrawn

JMCRThe editor of the Journal of Medical Case Reports, a BioMed Central title, has retracted and removed a case study of a novel surgical treatment after the patient’s legal guardian withdrew consent post-publication.

The paper, “Novel two-stage surgical treatment for Cantrell syndrome complicated by severe pulmonary hypertension: a case report,” describes the treatment of a six-month-old Han Chinese girl suffering from a rare combination of birth defects called Cantrell syndrome, complicated by pulmonary hypertension.

The original article, published in March 2014, has been removed from the journal’s website, though the abstract can be read on PubMed. It is unclear whether the authors, the child’s guardian, or some other party informed the editor of the withdrawal of consent.

The brief notice offers few details:

When should a paper be retracted? A tale from the obesity literature

obesity factsIn our line of work, we see it all — mega-corrections that don’t quite rise to the level of retraction, letters to the editor that point out seemingly fatal flaws in papers that remain untouched, and studies retracted for what seem like minor reasons. It can make you wonder what makes a paper worthy of a retraction. A recent case in an obesity journal may not provide a definitive answer, but it gives us a lot to chew on.

Here’s the story: In September 2013, Rosely Sichieri and a colleague from the State University of Rio de Janeiro submitted an article to Obesity Facts, “Unbalanced Baseline in School-Based Interventions to Prevent Obesity: Adjustment Can Lead to Bias?” The article examined statistical issues in randomized controlled trials of school-based weight loss programs. Peer reviewers said the paper needed major revisions before it could be accepted; the authors revised the paper enough in a second draft, submitted in November 2013, that the original reviewers accepted it. The paper was published in June 2014.

Then, in September 2014, a group of authors including David Allison of the University of Alabama, Birmingham, and colleagues from Clemson, Thomas Jefferson, and the University of Minnesota, wrote a critical letter that was published in the journal in April. The letter, according to a just-published editorial: Continue reading When should a paper be retracted? A tale from the obesity literature

Urology researcher in Iran up to six retractions

safarinejadA urologist in Iran has lost three papers in BJU International, bringing his retraction count to a half-dozen.

In December 2013, we reported on three retractions by Mohammad Reza Safarinejad. None of those notices, about papers related to incontinence and erectile dysfunction, made the reasons for retraction very clear. After that post ran, Safarinejad told us that Hartmut Porst, former president of the European Society for Sexual Medicine, had raised questions about the data in a number of his papers. Porst confirmed that for us earlier this month.

All of the latest papers, about aspects of male sexual dysfunction, are being retracted due to “inappropriate” statistical analyses.

Here’s the notice for “Analysis of association between the 5-HTTLPR and STin2 polymorphisms in the serotonin-transporter gene and clinical response to a selective serotonin reuptake inhibitor (sertraline) in patients with premature ejaculation,” which has been cited 17 times, according to Thomson Scientific’s Web of Knowledge: Continue reading Urology researcher in Iran up to six retractions

Does peer review ferret out the best science? New study tries to answer

scienceGrant reviewers at the U.S. National Institutes of Health are doing a pretty good job of spotting the best proposals and ranking them appropriately, according to a new study in Science out today.

Danielle Li at Harvard and Leila Agha at Boston University found that grant proposals that earn good scores lead to research that is more cited, more published, and published in high-impact journals. These findings were upheld even when they controlled for notoriously confounding factors, such as the applicant’s institutional quality, gender, history of funding and experience, and field.

Taking all those factors into consideration, grant scores that were 1 standard deviation lower (10.17 points, in the analysis) led to research that earned 15% fewer citations and 7% fewer papers, along with 19% fewer papers in top journals.

Li tells Retraction Watch that, while some scientists may not be surprised by these findings, previous research has suggested there isn’t much of a correlation between grant scores and outcomes:

Author from China blames translation company for plagiarism in retracted vascular paper

apjcpDo we need a “throwing vendors under the bus” category here at Retraction Watch?

Earlier this year, we reported on the retraction of a paper because of sloppy work by an outside lab. Now, we have the story of a retraction for “negligence” by a translator. Specifically, the author says the passages shared between the retracted 2015 vascular paper and another paper in EMBO Journal are a result of “negligence on the part of the translation company that I trusted to make my manuscript ready for submission.”

Here’s more from the notice in the Asian Pacific Journal of Cancer Prevention, written by Yong Jiang, of Laboratory Medical College, Jilin Medical College, China: Continue reading Author from China blames translation company for plagiarism in retracted vascular paper

Bielawski and Wiggins retraction count grows to six

Authorship issues spell retraction for breast cancer paper

ijmponcThe corresponding author of a 2014 paper in the Indian Journal of Medical and Paediatric Oncology has retracted the article because he was a bit too generous with his list of coauthors.

The article, “Outcome of neoadjuvant chemotherapy in locally advanced breast cancer: A tertiary care centre experience,” reviewed medical records from a local population of breast cancer patients treated with chemotherapy. It came from a group at the Post Graduate Institute of Medical Education and Research, in Chandigarh. The first author was Tapesh Bhattacharyya, followed by four other names.

According to the notice:  Continue reading Authorship issues spell retraction for breast cancer paper
