Journal expresses concern — we think — about papers by Surgisphere founder

More than six months after two of the world’s leading medical journals retracted papers on COVID-19 based on suspect data from a questionable company, a journal says it has cleared a raft of articles by the controversial founder of the firm. Or, has it? 

Vascular, a SAGE title, says it has investigated all papers in the journal by Sapan Desai that relied on  “a significant amount of data,” whatever that means. Desai, you’ll recall, founded Surgisphere, which is now famous for refusing to share its data in articles published in The Lancet and The New England Journal of Medicine

We counted 18 11 papers in Vascular on which Desai was a co-author. The journal says — in a rather oblique way — that all but two of the articles it examined either checked out or didn’t include enough data to raise alarms.

The expression of concern reads:

The grad student who found a fatal error that may affect lots of papers

A team of researchers in England has retracted a 2014 paper after a graduate student affiliated with the group found a fatal error while trying to replicate parts of the work — and which might affect similar studies by other scientists, as well.

The article, “Perceptual load affects spatial tuning of neuronal populations in human early visual cortex,” was written by Benjamin de Haas, then of the Institute of Cognitive Neuroscience at the University College London, and his colleagues at UCL. 

According to the retraction notice

An associate dean at the University of Miami stepped down from his post two weeks after agreeing to sanctions stemming from a finding of misconduct by a government watchdog, Retraction Watch has learned.

Yesterday, we reported that the U.S. Office of Research Integrity (ORI) found that Charles Downs, “engaged in research misconduct by intentionally, knowingly, or recklessly falsifying and/or fabricating data” in six federal grant applications while on the faculty of the University of Arizona.

Downs was appointed associate dean of Miami’s nursing school in 2018, and stepped down from the position on December 4, according to a university spokesperson. He remains an associate professor at the school.

A former researcher at the University of Arizona who is now was until last week an associate dean at the University of Miami “engaged in research misconduct by intentionally, knowingly, or recklessly falsifying and/or fabricating data” in six federal grant applications, according to a new finding by the U.S. Office of Research Integrity (ORI).

Charles A. Downs’ work “focuses on acute lung injury and pulmonary diseases,” according to a 2018 press release from the University of Miami announcing his appointment. He “neither admits nor denies ORI’s findings of research misconduct,” the ORI announced today. The agency said that Downs

Researcher at Tehran medical school loses three papers because “overlap without cross-referencing is not legitimated”

Hamid Akbari Javar

A pharmacy researcher at Tehran University of Medical Sciences has had three papers retracted, and one corrected, because he duplicated his other articles.

Hamid Akbari Javar is the common author on all four papers, which appear in the African Journal of Pharmacy and Pharmacology, the International Journal of Pharmaceutical Sciences and Research, the Indian Journal of Pharmaceutical Sciences, and the International Journal of Molecular Medicine

Narges Shokri, of the School of Pharmacy of Ardabil University of Medical Sciences, also in Iran, is an author of the three retracted papers, but not the corrected paper in the International Journal of Molecular Medicine.

Here’s the notice for “Comparison of Calcium Phosphate and Zinc Oxide Nanoparticles as Dermal Penetration Enhancers for Albumin,” in the Indian Journal of Pharmaceutical Sciences:

Western University materials scientist committed misconduct, according to investigation

Bernd Grohe

An investigation into the work of a researcher at Western University “resulted in a clear determination of research misconduct,” according to a retraction notice, but details are scant.

Here’s the notice for “Synthetic peptides derived from salivary proteins and the control of surface charge densities of dental surfaces improve the inhibition of dental calculus formation,” published in Materials Science and Engineering: C in 2017 by Bernd Grohe:

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:

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:
