Team in Japan earns third retraction for misconduct

without comments

JSRA team of researchers has earned its third retraction after an investigation at Oita University in Japan found instances of misconduct in their research.

The most recent notice mentions the investigation, and specifies that the first author, Satoshi Hagiwara, was responsible for the problematic figures in the paper. Hagiwara is also the first author on two retracted papers we reported on last year; one of the earlier retractions also mentions the investigation, but does not assign responsibility to any particular author. All three papers share three authors.

The retraction notice for “Continuous Hemodiafiltration Therapy Ameliorates LPS-Induced Systemic Inflammation in a Rat Model,” published in the Journal of Surgical Research, explains the issues with the paper:

Retraction count for Shigeaki Kato climbs to 39

Shigeaki Kato

We’ve found another retraction for Shigeaki Kato, number seven on our leaderboard.

Our count for Kato has now risen to 39; we added five retraction notices to our count for Kato last month. These notices follow an investigation at the University of Tokyo, where Kato used to work, which found 43 papers contained “likely altered or forged materials,” according to a 2013 news article from The Asahi Shimbun.

Here’s the retraction note for “1alpha,25(OH)2D3-induced DNA methylation suppresses the human CYP271B1 gene,” published in Molecular and Cellular Endocrinology:

Raw files help fix 2003 figure by heart researcher accused of fraud

with one comment


A researcher accused of misconduct by an anonymous Japanese blogger has corrected a 2003 paper in Circulation Research, after providing a university investigation with the original source files.

Allegations of fraud have dogged Shokei Kim-Mitsuyama for years, and even caused him to step down from his position as editor in chief at another journal. However, Kim-Mitsuyama and his colleagues call the latest correction a “mistake,” which didn’t affect any of the paper’s conclusions.

We’ve unearthed a total of five publications co-authored by Kim-Mitsuyama that have earned corrections, the latest of which cites an investigation by the university:

Poop paper flushed due to possible sample contamination

without comments

cover (3)The authors of a paper on a new probiotic strain of bacteria found in pig feces have retracted it from Animal Science Journal after discovering some of the bacteria might have been contaminated.

Readers likely know by now how easy it is for this to happen, as we frequently report on retractions due to similar reasons. Like other instances of mistaken cell identity, the authors of this 2013 paper realized the mistake following further tests of the bacteria used in the experiment.

The retraction for “Isolation, characterization, and effect of administration in vivo, a novel probiotic strain from pig feces

Shigeaki Kato up to 38 retractions

Shigeaki Kato

Shigeaki Kato

Our retraction notice count for Shigeaki Kato, number seven on our leaderboard, has grown to 38.

The former University of Tokyo endocrinologist recently earned another retraction, for a paper in Archives of Biochemistry and Biophysics that contained image manipulation. As we’ve noted before, Kato resigned from the university in 2012 as it investigated his work for misconduct; in 2013 a Japanese newspaper reported that the investigation had found 43 papers from his lab contained “likely altered or forged materials.”

In addition to the new retraction, we’ve dug up four others for Kato from the past few years, plus one correction. Two of the retraction notices mention an investigation at the University of Tokyo.

First, the retraction note for “Multiple co-activator complexes support ligand-induced transactivation function of VDR,” published in December:

Surgery studies lacked ethics committee approval

with 4 comments

3Surgery Today has pulled a pair of papers that share many authors because the studies they describe were not approved by an institutional ethics committee.

One describes a case in which the researchers removed a mass from a 64-year-old woman’s small intestine; the other describes how the authors removed a growth from a patient’s pancreas. They conclude that the surgery techniques used — like a laparoscopic pancreaticoduodenectomy, a take on the “Whipple Procedure” — can be “feasible, safe, and effective” in certain patients.

The papers share several authors, including a first author, Akihiro Cho, who’s affiliation on the papers is Chiba Cancer Center Hospital in Japan. They also share a retraction note, which explains how the journal learned of the issue:

STAP stem cell researcher Obokata loses another paper

with 4 comments

Nature protocols

The first author of two high-profile Nature retractions about a technique to easily create stem cells has lost another paper in Nature Protocols.

Haruko Obokata, once “a lab director’s dream,” according to The New Yorker, also had her PhD revoked from Waseda University last fall.

After learning of concerns that two figures are “very similar” and “some of the error bars look unevenly positioned,” the rest of the authors were unable to locate the raw data, according to the note. The journal could not reach Obokata for comment before publishing the retraction.

Reproducible subcutaneous transplantation of cell sheets into recipient mice” has been cited 21 times, according to Thomson Reuters Web of Science. It was published in June 2011, soon after Obokata earned her PhD.

2001 sepsis paper “deviates from the ethical standard of authorship,” says journal

with one comment

Screen Shot 2016-02-11 at 1.50.33 PMWe don’t have a lot of information on a recent retraction of a 2001 paper published in a Japanese journal — just a brief and strongly worded note explaining that it follows “a strict, extensive, and judicious review.”

The paper, retracted 14 years after it was published, describes patients in Okinawa, Japan who developed severe symptoms following infection by bacteria belonging to the Aeromonas genus. One example:

The one patient was a 15-year-old high school girl student, who had been healthy in her school life, was admitted to the hospital with a sudden onset of left thigh muscle pain and swelling. She subsequently went into septic shock and died one day after admission. Pathological examination on autopsy revealed massive gas formation, skin bullas and ulcers, and extensive severe soft tissue damage throughout the body.

Aeromonas species infection with severe clinical manifestation in Okinawa, Japan-association with gas gangrene” has been cited three times, according to Thomson Scientific’s Web of Knowledge. It was published in a Japanese journal, Rinsho Biseibutshu Jinsoku Shindan Kenkyukai Shi — which translates to the Journal of the Association for Rapid Method and Automation in Microbiology.

Journals retracts three bone papers for duplication by same author

with 4 comments

1-s2.0-S0168365907X02700-cov150hA journal is Journals are retracting three papers after a biomaterials researcher duplicated his own work, sometimes using the same figures to describe different experiments.

Two of the papers are on bone regeneration; one is about targeting tumors. In addition to issues with figures, two one of the retraction notes explain that the papers contain “widespread plagiarism of text” from other papers by the researcher, Hossein Hosseinkhani.

Hosseinkhani is currently affiliated with the National Taiwan University of Science and Technology; when he did the work in the now retracted papers, published in 2004 and 2007, he was based at Kyoto University Hospital and then National Institute for Materials Science in Japan.

The Journal of Controlled Release published all three two of the papers. Here’s the retraction note for “Bone regeneration through controlled release of bone morphogenetic protein-2 from 3-D tissue engineered nano-scaffold,” which has been cited 118 times, according to Thomson Scientific’s Web of Knowledge.

2001 Fujii papers retracted — finally. What took so long?

with one comment


Nearly four years after an analysis of more than 160 papers by Yoshitaka Fujii concluded the chances the data were authentic were infinitesimally small, the British Journal of Ophthalmology has decided to formally retract one of the papers included in that review.

The name Yoshitaka Fujii should ring a bell — an alarm bell, in fact — for our readers. He’s firmly listed in the number one spot on our leaderboard, with more than 180 retractions.

The recently retracted paper — “Ramosetron compared with granisetron for the prevention of vomiting following strabismus surgery in children” — has been included in that retraction total for years, because it was part of a seminal 2012 analysis by J.B. Carlisle that put the odds of data occurring naturally in some of Fujii’s papers at: Read the rest of this entry »
