Noriyuki Takai, a gynecologic cancer researcher in Japan, has notched one more retraction — bringing the total to eight — due to figures that were “processed inappropriately” and did “not accurately report the original data.”
According to the notice, Takai alone put the figures together in the 2006 Oncology paper, which tested a histone deacetylase inhibitor on endometrial and ovarian cancer cell lines. The team is part of the department of obstetrics and gynecology at Oita University in Japan.
Journal ISIJ International minced no words about why the 2014 paper on steel manufacturing was withdrawn, because there were no words. Here’s the notice for “Microstructure and Properties of Fiber Laser Welded Joints of Ultrahigh-strength Steel 22MnB5 and its Dissimilar Combination with Q235 Steel” in its entirety – half the length of the title!: Read the rest of this entry »
A new paper in the MDPI journal Publications reports that the only controlled study on the effect of giving COPD patients Omega-3 has been cited 52 times since being retracted. Of those, only two mentioned the retraction.
In 2005, Chest published an article that found that COPD patients who took omega-3 supplements for 2 years experienced improvements in their condition, such as better walking tests and a decrease in sputum cytokines. But when an institutional investigation found the lead author had falsified the data, the journal retracted the paper in 2008.
That’s news to many researchers in the field. Among the 50 papers that cited the research after 2008 without stating it had been retracted, 20 included “specific data” from the paper, while the other 30 “cited the reference in passing.” Articles citing the retracted study have themselves been cited 947 times total, pointing to the ripple effect this kind of unwitting mention can have throughout the literature.
Takeda group retracts paper after realizing “novel” compound had already been synthesized…by a colleague
A group of scientists at Takeda Pharmaceutical, including vice president Yoshinori Ikeura, has lost a paper after realizing that their “novel” compound had been previously synthesized by another Takeda researcher.
The 2011 paper, published in Elsevier journal Bioorganic & Medicinal Chemistry, was the subject of a 2012 corrigendum adding two authors to the paper. The retraction appeared online in December of this year.
Seems like they didn’t add enough authors, though. Read the rest of this entry »
Frequent Retraction Watch subject Hiroaki Matsubara resigned his post at Kyoto Prefectural University in 2013, after his work on valsartan was shown to be riddled with data errors and undisclosed conflicts of interest.
Also that year, suspicions about Chiba University hypertension researcher Issei Komuro’s work were first raised by an anonymous blog, which detailed numerous image manipulations in the researcher’s published works. Komuro, who frequently collaborated with Matsubara, has been a senior author on a number of valsartan papers, including the now-retracted one, which reported the results of Novartis-sponsored Valsartan Amlodipine Randomized Trial in 2011 without reporting the Novartis funding.
Former University of Tokyo researcher Shigeaki Kato continues to put big numbers on the board.
Last month, we reported on his 26th, 27th, and 28th retractions, all in Nature Cell Biology and cited close to 700 times. Yesterday, EMBO Journal and EMBO Reports published a total of five more retractions for the endocrinology researcher, who resigned from the university in 2012 following investigations found he had faked images.
Jaime A. Teixeira da Silva, Judit Dobránszki, Jean Carlos Cardoso, and Songjun Zeng had submitted the manuscript, “Genetic transformation of Dendrobium,” to GM Crops and Food: Biotechnology in Agriculture and the Food Chain earlier this year. It was accepted on July 29, and posted online on October 30.
Taylor and Francis — who recently took over the journal from Landes Biosciences — had requested $1,000 in page charges, and $340 in color charges. But Teixeira da Silva — who has been made persona non grata by an Elsevier journal following “personal attacks and threats,” and had a paper retracted by a Springer journal after he demanded the editors’ resignations — insisted in an email to the publisher that Read the rest of this entry »

Some, though, we’re just not qualified to understand, like this retracted paper in the Journal of Management Studies, which according to the abstract “demonstrates that the persistence of brokerage positions decreases broker performance.”
What is clear is the retraction: the author already published the conclusion in a Japanese management journal in 2011.
