Journal retracts two papers by Japanese cardiologist under investigation

matsubaraThe Circulation Journal, the official organ of the Japanese Circulation Society, is retracting two papers by Hiroaki Matsubara, lead researcher on the Kyoto Heart Study, for unreliable findings. Matsubara’s institution, Kyoto Prefectural University, confirmed to us last March that it was investigating the prominent cardiologist.

The work of Matsubara came into question last year when the American Heart Association issued an expression of concern for five papers the society published in its journals. Larry Husten, at Forbes/CardioBrief, reports today that the two retracted articles were “Effects of Valsartan on Cardiovascular Morbidity and Mortality in High-Risk Hypertensive Patients With New-Onset Diabetes Mellitus: Sub-Analysis of the KYOTO HEART Study,” published in September 2012; and “Enhanced cardiovascular protective effects of valsartan in high-risk hypertensive patients with left ventricular hypertrophy: Sub-analysis of the KYOTO HEART study,” which appeared in March 2011.

The retraction notice for the most recent paper states: Continue reading Journal retracts two papers by Japanese cardiologist under investigation

Journal of Neuroscience retraction, typically opaque, from author with history of errors

jneuroscienceThe Journal of Neuroscience has retracted a 2011 paper by an international group of scientists, including the prominent Maryland researcher Ronald Dubner, but readers won’t know why.

As the notice “explains“: Continue reading Journal of Neuroscience retraction, typically opaque, from author with history of errors

Failure at System — systems failure? — leads to duplicate publication, retraction

systemcoverThe journal System evidently needs a new one — at least when it comes to production.

The publication has been forced to retract an article that it published twice — in the same issue.

Here’s what happened: Continue reading Failure at System — systems failure? — leads to duplicate publication, retraction

Two Moriguchi stem cell papers being retracted

It was, as Nature News wrote last month, a story that “seemed too good to be true:”

Stem-cell transplant claims debunked

Transplant of induced pluripotent stem cells to treat heart failure probably never happened

Hisashi Moriguchi, a visiting researcher at the University of Tokyo, had claimed a result that would have put him years ahead of researchers toiling in stem cell research. But the claims were met with a great deal of doubt — to say the least — and the story began to unravel when Harvard, where Moriguchi said he’d done the work, denied it had ever taken place.

And as expected, the retractions have now started. Today, a Nature Publishing Group journal said they would be retracting two papers, “A therapeutic method for the direct reprogramming of human liver cancer cells with only chemicals” and “Successful cryopreservation of human ovarian cortex tissues using supercooling.” The notices for the Scientific Reports papers will both say the same thing: Continue reading Two Moriguchi stem cell papers being retracted

Three gynecologic cancer studies retracted for figure duplication, image manipulation

A gynecologic cancer researcher at Oita University in Japan has retracted three papers by his group after the discovery of duplicated figures and manipulated images.

The three papers by Noriyuki Takai and colleagues all appeared in Gynecologic Oncology: Continue reading Three gynecologic cancer studies retracted for figure duplication, image manipulation

Slew of retractions appears in Neuroscience Letters

We’re not sure how many you need for a “slew,” but we’ve seen five retractions in Neuroscience Letters recently, most of them because researchers republished translations of papers in English, so we thought we’d round them up in a post.

We’ll start the count — appropriately, we think — with the notice for “Simple mental arithmetic is not so simple: An ERP study of the split and odd–even effects in mental arithmetic“, published in February by researchers from Nanjing Normal University in China: Continue reading Slew of retractions appears in Neuroscience Letters

Eighteen years later, derm journal retracts overlapping article, citing editorial error

Eighteen years ago, the Journal of Dermatology published an article, “A sulfated proteoglycan as a novel ligand for CD44,” by a group of Japanese researchers (the journal is the official periodical of the Japanese Dermatological Society).

The JoD is now retracting that paper because it overlaps with another article by the same group, published a few months earlier in a different journal.

Here’s the notice (behind a pay wall — tsk, tsk, Wiley): Continue reading Eighteen years later, derm journal retracts overlapping article, citing editorial error

Former Tokyo Tech materials researcher sanctioned after bringing forward evidence of data fabrication

A materials researcher faced three months without salary, retired from his research position and may have to return a portion of a grant worth $1 million US as punishment after a postdoc in his lab was caught fabricating data.

Seizo Miyata, formerly a materials researcher at the Tokyo Institute of Technology, headed a group that worked on carbon alloy catalysts. Last year, Miyata told Retraction Watch, he found evidence that postdoc Wu Libin had fabricated data.

Reached by Retraction Watch by phone, Miyata didn’t say who uncovered the evidence, nor how, but when he confronted Libin, the postdoc confessed. Miyata said he alerted Texas Tokyo Tech administrators last year, and requested the retraction of “Preparation of carbon-based catalysts for PEFC cathodes from aromatic polyamide with Fe compound,” which appeared in Applied Catalysis A: General in July 2011. That retraction notice reads: Continue reading Former Tokyo Tech materials researcher sanctioned after bringing forward evidence of data fabrication

A correction for Alirio Melendez, in Journal of Cellular Physiology

We’ve been covering the case of Alirio Melendez, three of whose papers have been retracted amidst questions about almost 70 studies. The latest development is a correction in the Journal of Cellular Physiology, which has already retracted one of his papers, of a study on which he was a co-author.

Here’s the correction for “Short dysfunctional telomeres impair the repair of arsenite-induced oxidative damage in mouse cells”: Continue reading A correction for Alirio Melendez, in Journal of Cellular Physiology

Does anesthesiology have a problem? Final version of report suggests Fujii will take retraction record, with 172

Japanese investigators have concluded that Yoshitaka Fujii, an expert in postoperative nausea and vomiting whose findings drew scrutiny in 2000 but who continued to publish prolifically for a decade after, fabricated his results in at least 172 published studies.

That number nearly doubles that of the current unofficial retraction record holder, Joachim Boldt.

An inquiry by the Japanese Society of Anesthesiologists (JSA) has determined that Fujii, who was fired in February from his post at Toho University, falsified data in 172 of 212 papers published between 1993 and 2011. Investigators said they found no evidence of fraud in three of the papers, but could not determine whether the results reported in the remaining 37 were reliable.

Of the 172 bogus studies, 126 involved randomized controlled trials. Investigators believe this was not a coincidence: Continue reading Does anesthesiology have a problem? Final version of report suggests Fujii will take retraction record, with 172
