Cancer paper flagged due to “credible” concerns over its reliability, journal says

rsc-advancesA journal has issued an expression of concern (EOC) for a cancer study after the publisher received what it called a “credible” tip that its results may not be reliable.

According to the EOC, published in RSC Advances, the paper is now under investigation.

Here’s the EOC for “Filled and peptide-modified single-walled carbon nanotubes: synthesis, characterization, and in vitro test for cancer cell targeting:” Continue reading Cancer paper flagged due to “credible” concerns over its reliability, journal says

Parkinson’s researcher Caroline Barwood pleaded not guilty to fraud-related charges in a Brisbane courtroom Monday.

According to 9News, Barwood is accused of three counts of fraud, and four instances of attempted fraud, which include trying to obtain approximately $700,000 (AUD) from various organizations between 2011 and 2013 for a study that never occurred. The case follows an investigation at her former institution, the University of Queensland (UQ), which resulted in three of her papers being retracted. 

Crown Prosecutor Caroline Marco alleged that Barwood was also intimately involved with Bruce Murdoch, her former colleague at the UQ, who has pleaded guilty to 17-fraud related charges, and received a two-year suspended sentence earlier this year.

Marco also claimed that Barwood admitted that Continue reading Parkinson’s researcher in Australia pleads not guilty to fraud

Despite retraction, antipsychotics still effective, safe for dementia, says author

alzheimers-research-and-therapyResearchers have retracted a systematic review that suggested that antipsychotic drugs are effective and safe for patients with symptoms of dementia — but claim their re-analysis of the updated data still comes to the same conclusions.

According to the retraction notice in Alzheimer’s Research and Therapy, some participants were incorrectly included twice in the meta-analysis. 

The corresponding authors recently lost another paper for an entirely different reason — earlier this year, we reported on a retraction in Annals of Neurology for Jin-Tai Yu and Lan Tan, affiliated with the Ocean University of China, Qingdao University, and Nanjing Medical University in China. The authors pulled that paper after appearing to pass off others’ data as their own.

Here’s the retraction notice for the review, issued earlier this year: Continue reading Despite retraction, antipsychotics still effective, safe for dementia, says author

Authors fix three Diabetes papers flagged for image issues

diabetesResearchers have corrected three studies published in the journal Diabetes after users flagged issues with the images on PubPeer.

All three papers share a number of authors, including the same last and corresponding author, Aimin Xu, from The University of Hong Kong.

Since the corrections appear relatively extensive, we asked the journal if retractions were ever on the table. According to Chris Kohler, associate publisher, scholarly journals at American Diabetes Association, which publishes Diabetes, an ethical panel reviewed the papers before allowing the authors to issue the errata, all of which were published online this month: Continue reading Authors fix three Diabetes papers flagged for image issues

A high-profile plant scientist who has been racking up corrections and retractions at a steady clip has had another paper — this one from Science — retracted.

The retraction, of a paper that had been previously corrected, is the eighth for Olivier Voinnet. According to the notice, the correction did not address all the figure problems with the paper, which “cannot be considered the result of mistakes.”

Here’s the notice in full: Continue reading Eighth Voinnet paper retracted — this one from Science

Cancer researcher earns 5th retraction after misconduct finding

oncoimmunologyA cancer researcher has logged her fifth retraction following an investigation that concluded she had committed scientific misconduct.

We’ve previously reported on four retractions of papers by Stephanie Watkins, a researcher at Loyola Medicine. The previously issued notices — in The Journal of Clinical Investigation and Cancer Research — note that an investigation committee appointed by the National Institutes of Health (NIH) found Watkins to be solely responsible for the misconduct, with none of the co-authors aware of it.

The editor of OncoImmunology previously informed us that the journal was investigating another one of Watkins’ papers; the journal has now pulled that paper, citing “fabrication and falsification of data” in the original studies referenced in the paper.

Here’s the retraction notice, published online earlier this year: Continue reading Cancer researcher earns 5th retraction after misconduct finding

Retraction notice for GMO paper updated to include fraud

fns2015012717103119Earlier this year, a nutrition journal retracted an article about the potential dangers of eating food containing genetically modified organisms (GMOs), noting the paper contained a duplicated image.

At the time, news outlets in Italy were reporting accusations that the last author, Federico Infascelli, an animal nutrition researcher at the University of Naples, had falsified some of his research.

Food and Nutrition Sciences has now updated its initial notice, saying the paper was pulled for data fabrication. In addition, Infascelli is no longer listed on its editorial board – he is included on an archived link to the editorial board from March 2016, but not on the current list of members.

Here is the updated version of the retraction notice for “Gamma-Glutamyl Transferase Activity in Kids Born from Goats Fed Genetically Modified Soybean:” Continue reading Retraction notice for GMO paper updated to include fraud

Gov’t researchers lose three papers for data doctoring

Eukaryotic Cell A researcher in New Mexico has retracted three papers tainted by fraud.

Lead author Samuel Lee, who works at the New Mexico Veterans Affairs (VA) Healthcare System and the University of New Mexico (UNM), requested Eukaryotic Cell retract two papers after identifying multiple instances of fabricated or falsified data. He requested the retraction of a review article based on those papers as well.

In addition, the research is subject to an investigation, Ellie Ghatineh, a production editor at the journal, told us:

Cardiovascular researcher in Taiwan logs four retractions

clinical-scienceA researcher has earned four retractions following an investigation at his institutions in Taiwan.

The retraction notices, which appear in Clinical Science, mention investigations into the work of Kou-Gi Shyu at the Shin-Kong Wu Ho-Su Memorial Hospital and Taipei Medical University (TMU).

Shyu is listed as being affiliated with both institutions in the original papers, but a TMU official told us Shyu left his teaching role at TMU amidst the probe. Shyr-Yi Lin, professor of medicine and dean of research and development at TMU, noted: Continue reading Cardiovascular researcher in Taiwan logs four retractions

Cancer biologist says Nature journal “censored” his News & Views, retracts it

nature-reviews-clinical-oncologyA cancer biologist has retracted a 2016 News & Views article in a Nature journal, alleging that the journal tried to censor his writing by asking him to remove passages that criticized another journal (Cell). 

Carlo Croce, the sole author of the article in Nature Reviews Clinical Oncology from Ohio State University in Columbus, described the journal’s actions to us as “disgusting” and “worrisome.”

A spokesperson from the journal sent us this statement:

We regret that this situation occurred. We cannot comment beyond the retraction notice.

This isn’t Croce’s first retraction (we just found another recent one, in the Journal of Biological Chemistry, over image problems). He’s also co-authored multiple papers with Alfredo Fusco, a cancer researcher in Italy who has nine retractions under his belt, and is undergoing criminal investigation for scientific misconduct.

Here’s the retraction notice, published in Nature Reviews Clinical Oncology on October 4: Continue reading Cancer biologist says Nature journal “censored” his News & Views, retracts it
