Death, retirement, and inability to contact authors leads to retraction of paper first flagged five years ago

More than five years after comments appeared on PubPeer about a 2012 paper in PLoS ONE with a raft of problematic images — and a deceased member of the group whom the corresponding author suggests might have been able to support the validity of the data — the journal has retracted the article.

The article, “Placental expression of CD100, CD72 and CD45 is dysregulated in human miscarriage,” was written by a team of researchers at the Università Politecnica delle Marche, in Ancona, Italy. The first, and corresponding, author of the paper was Teresa Lorenzi, of the school’s Division of Neuroscience and Cell Biology.

The paper has 19 citations, including two in 2019, according to Clarivate Analytics’ Web of Science. The lengthy notice begins with a rundown of 14 questions about three of the paper’s figures. We’ll spare you the entire catalog of ships, but here are a few examples:

Two spectrometry papers retracted, one for “intolerable” mistakes. The authors don’t agree.

Saudi researchers have lost a pair of papers in a spectrometry journal for errors the editors found fatal but the authors apparently dismiss as trivial. 

The articles appeared in the Journal of Analytical Atomic Spectrometry, published by the Royal Society of Chemistry in the United Kingdom. The principal author on both papers is Mohammad Gondal, of the King Fahd University of Petroleum and Minerals in Dharhan. According to his website, Gondal is a highly decorated physicist, with

‘The methodology does not generate the results’: Journal corrects accounting study with flawed methods

What a difference a Yi,t=β0+β1IOˆi,t+β2Xi,t+ωt+εi,t.Yi,t=β0+β1IO^i,t+β2Xi,t+ωt+εi,t. makes.

The authors of a 2016 paper on institutional investing have corrected their article — to include the equation above — in the wake of persistent questions about their methodology. The move follows the protracted retraction earlier this year of a similar article in The Accounting Review by the duo, Andrew Bird and Stephen Karolyi, of Carnegie Mellon University in Pittsburgh, for related problems.

The bottom line, it seems, is that Bird and Karolyi appear to be unable adequately to explain their research methods in ways that stand up to scrutiny. 

The correction involves a paper published in The Review of Financial Studies, from Oxford University Press, titled “Do institutional investors demand public disclosure. According to the statement (the meat of which is behind a paywall):

A failure at Renal Failure leads to retraction of duplicate article

A kidney journal has retracted a 2019 paper by a group of researchers in China for an unfortunate own-goal. 

The article, “The relationship between hemodialysis mortality and the Chinese medical insurance type,” was first published in January in Renal Failure, a Taylor & Francis title. It appeared again in the journal nine months later. 

According to the retraction notice

‘Reused over and over again:’ Image recycling leads to 5-year funding ban for cancer researcher

Sudhakar Yakkanti

A former researcher at Boys Town National Research Hospital in Nebraska has agreed to a five-year ban from the U.S. Office of Research Integrity (ORI) on receiving federal science funding after being found guilty of having fabricated data in numerous grant applications and articles. 

According to the ORI, Sudhakar Yakkanti, a Harvard-trained cancer specialist who from 2004 to 2012 held the post of Director of the Cell Signaling, Retinal & Tumor Angiogenesis Laboratory at Boys Town:

A former postdoc at Johns Hopkins University has been hit by the U.S. Office of Research Integrity (ORI) with a four-year ban on receiving federal research funding after being found  guilty of misconduct in several studies and her doctoral dissertation. 

We covered problems with several of Deepti Malhotra’s papers in February of 2016. At the time, Hopkins refused to tell us if the issues stemmed from misconduct.  But nearly four years later, the ORI has announced that Deepti Malhotra, while at the Johns Hopkins Bloomberg School of Public Health:

What’s the hernia? Authors lose surgery paper for miscounting cases

Inguinal hernia

A group of pediatric surgeons in China has lost their 2016 paper on a technique for repairing abdominal defects in children because they apparently had trouble keeping those defects straight. 

The article, “A new technique for extraperitoneal repair of inguinal hernia,” appeared in the Journal of Surgical Research, an Elsevier title. The authors reported that a laparoscopic method of repairing inguinal hernias in children was superior to conventional, open surgery. According to the authors, they had nearly 1,900 patients to prove their point. 

But as the retraction notice indicates, the numbers didn’t add up.

Stem cell researchers have papers retracted for image manipulation

A group of dentistry researchers in Japan, whose work on stem cells has been the subject of an institutional investigation, have now lost two papers in PLOS ONE for image problems. 

The authors, from Aichi Gakuin University in Nagoya, were led by Makio Mogi, a medicinal biochemist at the school. Mogi asked for at least one of the retractions. 

The first article, published in 2013, was titled “Matrix metalloproteinase-3 in odontoblastic cells derived from Ips cells: unique proliferation response as odontoblastic cells derived from ES cells.” It has been cited 18 times, according to Clarivate Analytics’ Web of Science. According to the notice

Feds ban ex-Duke lab tech from funding after she faked data linked to 60 NIH grants

The Duke Chapel

Erin Potts-Kant, who lost her job as a researcher at Duke University in 2013 for embezzling more than $25,000 from the institution, has received a rare permanent Federal funding ban from the U.S. Office of Research Integrity (ORI) after investigators concluded that she had used fabricated data in nearly 120 figures. 

The case has been ongoing since 2013. Potts-Kant and a former colleague, William Michael Foster, were named in a 2015 whistleblower lawsuit which alleged that they, with the knowledge of their institution, had used bogus data to collect hundreds of millions of dollars in government grants. Earlier this year, Duke settled the case for $112.5 million, of which nearly $34 million went to the whistleblower, Joseph Thomas.  

According to an ORI finding issued today, investigators determined that Potts-Kant

PLOS ONE realizes an academic editor had a conflict of interest that the publisher says it now tries harder to avoid

A group of genetics researchers in Italy has lost a 2014 paper in PLOS ONE for a range of image problems and a glaring conflict of interest. 

The article, titled “Neuronal differentiation dictates estrogen-dependent survival and ERK1/2 kinetic by means of caveolin-1,” came from a team led by Luca Colucci-D’Amato, of the Second University of Naples. 

The retraction notice in PLOS ONE lays out a raft of issues with the paper, for example:
