“Questioned as implausible:” Journal retracts paper because a researcher claimed to perform a large clinical trial single-handedly

Is it possible for just one researcher to perform a clinical trial of more than 200 participants?

According to the editorial board of the European Journal of Obstetrics & Gynecology and Reproductive Biology, an Elsevier title, the answer would seem to be no. The journal has decided to retract a 2016 paper in which the author claimed to have conducted such a large trial on their own.

Here’s the notice for “Calcium versus oral contraceptive pills containing drospirenone for the treatment of mild to moderate premenstrual syndrome: A double blind randomized placebo controlled trial:”

“A flooding accident:” Engineer has seven papers retracted at once

A chemical engineer in China who claims his supporting data were wiped out in a flood has notched his ninth retraction, seven from a single journal, for suspicious images and related issues.

The work of Dong Ge Tong, of Chengdu University of Technology, had come under scrutiny in PubPeer, and several of his articles received expressions of concern before ultimately falling to retraction.

Last week, the Journal of Materials Chemistry A pulled seven papers on which Tong was an author. Here’s the notice for one of those articles, “Hollow amorphous NaFePO4 nanospheres as a high-capacity and high-rate cathode for sodium-ion batteries,” first published in 2015:

UCLA group has three papers retracted

The Journal of Biological Chemistry has retracted three papers by a group from the University of California, Los Angeles, citing problems with the figures.

Two of the papers, published in 2002, 2004 and 2009, have the same last author, Mark H. Doolittle, who is the first author of the most recent article. Doolittle, who appears to be a highly talented woodworker, has left UCLA and did not respond to a request for comment.

The retraction notice for the 2002 paper, “Maturation of lipoprotein lipase in the endoplasmic reticulum: Concurrent formation of functional dimers and inactive aggregates,” states:

Cancer researcher up to five retractions

A researcher in India is up to five retractions, by our count, for problematic data and image issues.

The latest retractions involve articles published in 2008 and 2013 in the journal Life Sciences. The last author on the papers is Yogeshwer Shukla, of the Council of Scientific and Industrial Research, about whom we have previously written.

The first paper, “Resveratrol induces apoptosis involving mitochondrial pathways in mouse skin tumorigenesis,” is rife with image problems:

University of Kentucky moves to fire researchers after misconduct finding

The University of Kentucky has started termination proceedings against a pair of scientists found guilty of “significant departures from accepted practices of research,” according to the institution.

The scientists, Xianglin Shi, who up until now had held the William A. Marquard Chair in Cancer Research and served as associate dean for research integration in the UK College of Medicine, and Zhuo Zhang in the Department of Toxicology and Cancer Biology in the College of Medicine, have lost access to their laboratories, which are shuttered, and other university equipment, UK said in a statement. A third researcher, Donghern Kim, who worked under Zhang, already has been fired in the scandal.

In October, the university told us that it was aware of the retractions but “not able to provide more information at this time.” The ongoing investigation was first reported in April by the Lexington Herald-Leader.

According to the UK’s announcement today, the inquiry, which began in June 2018, into Shi, Zhang and Kim found that:

Journals retract more than a dozen studies from China that may have used executed prisoners’ organs

Wendy Rogers, who has called attention to questionable papers

In the past month, PLOS ONE and Transplantation have retracted fifteen studies by authors in China because of suspicions that the authors may have used organs from executed prisoners.

All of the original studies — seven in Transplantation, and eight in PLOS ONE — were published between 2008 and 2014. Two involved kidney transplants, and the rest involved liver transplants. Two other journals, the Clinical Journal of the American Society of Nephrology and Kidney International, have recently issued expressions of concern for the same reason.

In an editorial explaining the seven retractions from its journal, the editors of Transplantation write:

Aluminum paper foiled by slew of errors

The authors of a 2019 paper on the properties of an aluminum alloy have retracted the work because, well, it was pretty much wrong.

The article, “Effect of ultrasonic temperature and output power on microstructure and mechanical properties of as-cast 6063 aluminum alloy,” appeared in the March issue of the Journal of Alloys and Compounds, an Elsevier title. The authors are affiliated with Taiyuan University of Science and Technology in China.

According to the abstract:

Materials scientist up to five retractions as publishers investigate dozens of his papers

A materials scientist in Australia, by way of Iran, has recently had five papers retracted for duplicating his prior work, and the reader who brought the issue to publishers’ attention says it could affect some 100 articles.

Ali Nazari, now of Swinburne University of Technology in Australia, was at Islamic Azad University in Iran when he published the five papers in Energy and Buildings, an Elsevier title, in 2010 and 2011. The retractions came sometime after January of this year, when an anonymous reader contacted Elsevier about dozens of Nazari’s papers.

A typical notice, for “Physical, mechanical and thermal properties of concrete in different curing media containing ZnO2 nanoparticles,” reads:

Journal expresses a great deal of concern over deceased author’s work

A gastroenterology journal has issued an extensive expression of concern about a 2013 paper by Yoshihiro Sato, a Japanese endocrinologist who has posthumously been climbing the Retraction Watch leaderboard. (He’s now ranked number three, ahead of Diederik Stapel.)

To call the statement an “expression of concern” is like calling Charles M. Schulz a talented cartoonist, or Escoffier a pretty good cook. Indeed, the journal expresses so much concern, about, well, so much, that we’re not sure what in the paper would be left unscathed.

Sato, formerly of Hirosaki University, currently has 77 retractions for a range of misconduct-related issues including likely data fabrication and duplication.

Authors object as “doubtful” data doom dermatology paper

A dermatology journal has retracted a 2017 article by a pair of researchers in Saudi Arabia after receiving a “serious complaint” about the integrity of the data. But the first author of the paper pushed back, saying the move was unjustified.

The article, “Successful use of combined corticosteroids and rituximab in a patient with refractory cutaneous polyarteritis nodosa,” was written by Ibrahim Al-Homood and Mohammad Aljahlan, rheumatologists at King Fahad Medical City in Riyadh and appeared in the Journal of Dermatology & Dermatologic Surgery. It described (with rather grisly pictures) the case of a 25-year-old man with severe leg ulcers that resolved after the described combination therapy.

But at the notice explains, the paper can’t be trusted:
