A year after a federal misconduct finding, a cancer researcher loses a paper

Sudhakar Yakkanti

A cancer specialist formerly affiliated with Boys Town National Research Hospital in Nebraska who was found to have committed misconduct in nearly 20 grant applications and papers has lost an article in Scientific Reports — a year after his misconduct case became public. 

According to the journal, which, to its credit, flagged the paper with an editor’s note last February, the delay stemmed from efforts to verify information that was not part of the official inquiry. 

The article, “Type IV collagen α1-chain noncollagenous domain blocks MMP-2 activation both in-vitro and in-vivo,” was written by a group led by Yakkanti Akul Sudhakar, whose name — last, at least — might be familiar to RW readers. 

In November 2019, Sudhakar — who also has published as Sudhakar Yakkanti and Akulapalli Sudhakar — was sanctioned by the U.S. Office of Research Integrity for:

Stem cell researchers lose two more papers, making three

A Hindawi journal has retracted two 2013 papers by a group of stem cell researchers in China over issues with the images in the articles, bringing their count to three.  

Here’s the notice for “Side-by-Side comparison of the biological characteristics of human umbilical cord and adipose tissue-derived mesenchymal stem cells,” by Lili Chen and colleagues from Huazhong University of Science and Technology in Wuhan:

Johns Hopkins student newspaper deletes, then retracts, article on faculty member’s presentation about COVID-19 deaths

A student newspaper at Johns Hopkins has retracted an article claiming that COVID-19 has had “relatively no effect on deaths in the United States.”

The article, “A closer look at U.S. deaths due to COVID-19” (link from the Wayback Machine) was published on November 22 and relied on a presentation by Genevieve Briand, assistant program director of the Applied Economics master’s degree program at Hopkins. 

From the article:

Subtraction by addition: A journal expresses concern again — but this time, with feeling

A journal published by the Royal Society in the United Kingdom has issued an updated expression of concern for a 2018 paper by a mathematician whose work has been the subject of intense scrutiny on this website and elsewhere. But the notice is less of a statement of problems than a rationalization.

The paper, “Quantum correlations are weaved by the spinors of the Euclidean primitives,” was written by Joy Christian, of the “Einstein Centre for Local-Realistic Physics in Oxford.” In May 2018, the journal issued an initial EoC about the article, stating:

The Office of Research Integrity (ORI) found that David Panka

Stem cell researcher’s retraction count may near two dozen

A stem cell researcher in Japan could end up with 23 retractions after officials at his former institution confirmed that he’d committed research misconduct in nearly two dozen papers. 

According to a report released last week by Aichi Gakuin University, Nobuaki Ozeki misused images, fabricated data and recycled text in 20 papers. Ozeki has had 19 papers retracted to date, 17 of which are described in the analysis. The latest report — an offshoot of one in 2018 that found he had committed misconduct in three papers — expands Ozeki’s liability to 22 articles. 

Ozeki has roughly 40 indexed journal articles on his CV, however, and journals may decide to conduct their own investigations into his work. Articles in the International Journal of Medical Sciences, Differentiation, and the Journal of Endodontics were named in the report but so far remain intact.

Psychologist’s paper retracted after Dutch national body affirms misconduct findings

Lorenza Calzato

A cognitive psychologist in Germany has lost one of two papers slated for retraction after her former institution found her guilty of misconduct. 

In a 2019 report, Leiden University found that Lorenza Colzato, now of TU Dresden, had failed to obtain ethics ethics approval for some of her studies, manipulated her data and fabricated results in grant applications. Although the institution did not identify Colzato by name, Retraction Watch confirmed her identity. 

The Leiden report — the conclusions of which were affirmed by the Netherlands Board on Research Integrity last month — called for the retraction of two papers by Colzato and her co-authors, three of whom acted as whistleblowers in the case. As the trio told us in an interview last December:
