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 »

Retractions follow misconduct by biologist, one more on the way

with one comment

Screen Shot 2016-01-06 at 11.11.12 AM

Two journals have retracted papers by a biologist at the University of Tokyo who admitted to scientific misconduct, including data duplication and misrepresentation. Another journal is planning to retract one of the researcher’s papers later this month.

Hyun Kim studies a protein known as the “ski protein.” However, one analysis of the role of ski protein in development was retracted late last month by the Asian-Australasian Journal of Animal Sciences. The journal decided to investigate after Kim admitted to misconduct in two other papers published in a different journal.

Here’s the note for the paper:

Osteoporosis paper felled by concerns with “scientific integrity”

with one comment

cover (3)

A paper suggesting that exposure to sunlight might help prevent hip fractures in the elderly has been retracted, due to duplication and “concerns about the underlying data.”

An expression of concern that appeared last July flagged the 2005 paper as containing text that matched another paper with the same first author that was published in 2011. According to the publisher, that duplicated text sparked a closer look at the text, which raised concerns about the scientific integrity of the paper.

The retraction note, published by the Journal of Bone and Mineral Research, says that the first author was responsible for the content of the paper: Read the rest of this entry »

When a paper is retracted, so is its previous correction–sometimes

without comments

1-s2.0-S0968089612X0018X-cov150hSometimes, the path to correcting the scientific record takes a few turns. In the case of a paper about a new cancer compound, authorship issues led to a correction and, ultimately, a retraction — along with a double-back to retract the earlier correction.

We reported on the first part of the story back in January: A 2011 paper that described a novel compound that could work as a drug for the side effects of chemotherapy was corrected in 2012 to add additional authors. But once the authors realized their supposedly novel compound had actually been synthesized by another author, they decided to retract the paper from Bioorganic and Medicinal Chemistry earlier this year, concluding “these facts made the paper inappropriate and unfaithful.”

Apparently, around the same time, the authors decided to retract the earlier correction, as well:

University revokes PhD of first author on retracted STAP stem cell papers

with 4 comments

800px-Waseda_University_Logo.svgWaseda University has revoked the doctorate degree of the first author on the now-retracted Nature papers about a technique to create stem cells.

The technique — which claimed to provide a new way to nudge young cells from mice into pluripotency — was initially described in two 2014 Nature papers, both first-authored by Haruko Obokata. However, the papers were soon mired in controversy, corrected, then retracted later that year due to “several critical errors,” some of which were categorized by a RIKEN investigation as misconduct.

Shortly after Nature retracted the two papers, Waseda revoked Obokata’s doctorate degree — on a probationary basis, according to the university: Read the rest of this entry »

“Insufficient permission” from funder resects liver disease paper

without comments

HepatologyA study on chronic liver inflammation was pulled from the journal Hepatology because of “insufficient permission by the authors’ funding institution to submit and publish the manuscript.” 

The paper, which was published in July, looked into how steatosis, the abnormal retention of fat in the liver, turns into steatohepatitis, also known as fatty liver disease. Researchers found that Treg cells play a central role in controlling the disease.

Unfortunately, the journal’s managing editor didn’t provide any information about the nature of the permission problems, and the notice doesn’t give any details.

Here it isin full:

Mirror image in plant study flagged on PubPeer grows into retraction

with 8 comments

djs_mpmi_28_9_cover-online.inddA 2010 paper on plant fungus has been retracted after a comment on PubPeer revealed that a study image had been flipped over and reused to represent two different treatments.

In May, a commenter pointed out the plants in Figure 2a of the paper in the journal Molecular Plant-Microbe Interactions “look remarkably similar.” A commenter writing under the name of corresponding author, Yukio Tosa at Kobe University in Japan, posted a response two days later agreeing with the assessment and stating that the paper should be retracted.

When the title states the wrong result, a paper gets corrected

with 5 comments


Ever wonder why, on a round-trip, the leg home often feels shorter? A group of researchers found that’s only true in hindsight, as people look back on which leg felt shorter — the trouble is, when the paper first appeared, the title mistakenly stated the opposite was true.

One June 10, PLOS ONE published a paper entitled “The Return Trip Is Felt Longer Only Postdictively: A Psychophysiological Study of the Return Trip Effect”; 17 days later, it was republished under the correct title, “The Return Trip Is Felt Shorter Only Postdictively: A Psychophysiological Study of the Return Trip Effect.”

On July 15, the journal posted a correction notice explaining its mistake:

Researchers suspended in Japan for funding violations

Hokkaido University has suspended two of its professors after an investigation found “improper receipt of research funding.”

One member of the team was awarded more than 15 million yen (roughly $120,000 USD) in research grants from the Japan Society for the Promotion of Science (JSPS), according to the official statement (translated by One Hour Translation).

The researchers share a last name. Hiroyoshi Ariga, a professor of Biomedical and Pharmaceutical Science and the head of a university lab, was given 8 million yen in 2006 and 7.5 million in 2007. It appears that Sanae Ariga also received funds for a similar study, based on the translation:

Ethics dispute forces retraction of paper on Hep C in Japanese leper colony

without comments

jcmcoverHere’s a case of retraction being a hammer when a scalpel might have been better.

The authors of a 2011 paper in the Journal of Clinical Microbiology looking at transmission of hepatitis C in a former leper colony in Japan have retracted the article because an ethics panel in that country objected to the scientists’ use of fetal tissue.

The article involves a controversial aspect of modern Japanese history — the country’s efforts to eradicate leprosy, or Hansen’s disease, by isolating patients in a string of state-run sanatoriums. The policy was eventually realized to be unnecessary and ruled unconstitutional in 2001, triggering a wave of apologies to patients and their families.
