Genetics study flagged for reliability issues by Frontiers journal

frontiers-in-geneticsA genetics journal has issued an expression of concern (EOC) for a study after an investigation by its chief editors.

According to the notice in Frontiers in Genetics, the authors of the paper — based at Hokkaido University in Sapporo, Japan — are conducting further experiments to resolve the issues raised by the journal’s investigation.

In February, the same paper received a corrigendum due to errors in the assembly of one of the figures.

Here’s the EOC, issued earlier this week: Continue reading Genetics study flagged for reliability issues by Frontiers journal

Second paper about major blood pressure drug trial in Japan to be retracted

hr_cimageA second paper about a major randomized trial in Japanese patients with heart disease is being retracted, after an investigation reportedly found multiple problems with the paper.

As predicted by Pharma Japan, Hypertension Research is retracting a 2011 paper, already the subject of two errata. Although a spokesperson said she couldn’t say why the paper was being retracted, as the notice was still in production, editor Toshihiko Ishimitsu told us: Continue reading Second paper about major blood pressure drug trial in Japan to be retracted

Two more retractions bring bone researcher’s total to 12

jbmrA bone researcher based in Japan with 10 retractions under his belt has retracted two more papers for similar reasons — problems with the underlying data, and including co-authors who didn’t participate in the project.

In both notices, Yoshihiro Sato is pegged as responsible for the content of the papers. The newly retracted research covers a long timespan — one paper was published in 2000, the other in 2013.

Here’s the first notice, issued by the Journal of Bone and Mineral Research:  Continue reading Two more retractions bring bone researcher’s total to 12

Anesthesia journal pulls study lacking patient consent

Journal of AnesthesiaAn anesthesia journal has retracted a paper after an author admitted that the study did not obtain appropriate consent from patients receiving a neuromuscular block in muscles on the face and hands. 

The first author, Yuhji Saitoh, has the same name as a co-author of Yoshitaka Fujii, the all-time record holder with 183 retractions listed on our leaderboard. Thirty-six of those retracted papers include a co-author with the name of Yuhji Saitoh, but we were unable to confirm this is the same person listed on the newly retracted paper.  

Here’s the retraction notice, issued by the Journal of Anesthesia on August 11: Continue reading Anesthesia journal pulls study lacking patient consent

More than half of plant toxicity paper isn’t original, journal says

Plagiarism and duplication can be deadly to a paper in any dose. In the case of a study on the toxicity of nanoparticles to plants, the publisher has presented the precise amount of plagiarism and duplications that ultimately felled the paper.

Specifically, according to Nanomaterials, 56% of “Potential Impact of Multi-Walled Carbon Nanotubes Exposure to the Seedling Stage of Selected Plant Species” was taken from other work.

Here are more details from the retraction notice, published last year:

Four more retractions for biomaterials researcher brings total to 7

Journal of Controlled ReleaseA biomaterials researcher has lost four more papers for figure-related issues such as duplications, bringing his total to seven retractions.

We previously reported on three retractions — two by the Journal of Controlled Release (JCR) — of papers co-authored by Hossein Hosseinkhani, who is currently based at the National Taiwan University of Science and Technology in Taipei. Now, the JCR is pulling four more studies that list Hosseinkhani as a co-author.

Here’s the retraction notice for “Enhanced expression of plasmid dna – cationized gelatin complex by ultrasound in murine muscle:” Continue reading Four more retractions for biomaterials researcher brings total to 7

“Great shock and sadness:” Publishing gadfly to retract paper for duplication

untitledA vociferous advocate for correcting the literature — who has been banned by two publishers for his persistent communications — has asked journals to retract one paper and correct three others for duplications.

After a reader flagged his 2004 paper on PubPeer last month, author Jaime Teixeira da Silva “immediately” contacted the journal to alert it that the paper had been duplicated, as he noted on a recent comment on our site:

You’ve been dupe’d (again): Do these data look familiar? They are

plant_growth_regulationWe can’t keep up with the growing number of retraction notices, so we’ve compiled a list of recent duplications to update our records.

1. Authors don’t always intentionally duplicate their own work, of course. The first paper on our list was retracted after the authors included a figure from a previous paper by accident, according to the publisher: Continue reading You’ve been dupe’d (again): Do these data look familiar? They are

Sixth retraction appears for bone researcher due to “extensive self-plagiarism”

cov150hA bone researcher in Japan has logged his sixth retraction, after acknowledging he duplicated substantial portions of a 2011 paper and added “honorary” co-authors.

The retraction, in Parkinsonism & Related Disorders, follows five others for Yoshihiro Sato, including one from JAMA, some of which were pulled over concerns regarding authorship and data integrity. The latest retraction duplicated text from another 2005 paper that was itself retracted last year, both for duplicating from this newly retracted paper and for “concerns about the underlying data.”

Sato — who is listed at Mitate Hospital on the paper — told the journal he takes full responsibility.

Here’s the retraction notice: Continue reading Sixth retraction appears for bone researcher due to “extensive self-plagiarism”

“All co-authors are honorary:” Team earns fifth retraction

Movement DisordersA team of researchers from Japan has earned a fifth retraction, after co-authors told the journal that they did not participate in much of the paper.

Yoshihiro Sato, listed at Mitate Hospital, is the only author of the paper who was not “honorary,” the managing editor of the journal confirmed. He and the same co-authors recently lost three other papers about preventing hip fractures for “concerns regarding data integrity” and authorship issues — one of those papers, published in JAMA, specified that Sato was responsible for the data. All four authors were also included in a retraction last year of a paper with “concerns about the underlying data;” there, too, Sato said his co-authors were named “for honorary reasons.”

Here’s the retraction notice for “Alendronate and vitamin D2 for prevention of hip fracture in Parkinson’s disease: A randomized controlled trial,” published in Movement Disorders:
