Chemist who cooked data claims PhD years after it was revoked

By the time Shiladitya Sen was officially declared guilty of research misconduct in 2018 by U.S. federal officials, The Ohio State University had long since stripped him of his doctorate in chemistry.

Years later, however, Sen is still billing himself as a PhD in the signature of his work email at a company that provides lab mice and other animals to many scientists, Retraction Watch has learned.

Sen, now a director of analytical chemistry at Charles River Laboratories, with headquarters in Wilmington, Mass., confirmed to us by phone that he has not earned another doctoral degree. He hung up when asked why his email signature claims he has a PhD.

Harvard surgeon has five papers pulled following internal investigation

Citing an investigation by Harvard Medical School and Brigham and Women’s Hospital, two journals last week retracted five articles by Edward Whang, an associate professor of surgery at the school.

The journals, Oncogene and Surgery, both refer to problems with images of Western blots that could not be resolved because “no underlying research data” were available, according to the investigation.

Questions have loomed over Whang’s research for a decade, and more than 20 of his studies have been flagged on PubPeer for possible image problems. As one commenter wrote in 2014 about one of the now-retracted papers, “It is perhaps fortunate that figure assembly and liver surgery require such unrelated skill sets.”

It is not clear how many of Whang’s papers were affected by the investigation. We reached out to Harvard Medical School for more details, but it declined to share information about the investigation.

Five years on, convicted transplant surgeon earns expressions of concern from Lancet

In 2018, when The Lancet pulled two studies by once-celebrated transplant surgeon Paolo Macchiarini after he was found guilty of misconduct, we suggested in a post that the journal’s chapter of the long-running Macchiarini saga was finally over.

We were wrong.

Last week, the journal issued expressions of concern about a pair of papers by the Italian doctor, who is currently on probation after a court in Sweden convicted him of causing bodily harm to a patient.

‘I was fired up’: Psychiatrist effort prompts retraction of antidepressant treatment paper

Eric Ross was listening to a popular psychiatry podcast one day last spring when “some pretty remarkable” research findings caught his attention.

A team of researchers in Egypt had shown that adding a cheap diabetes drug—metformin—to antidepressant therapy nearly doubled the treatment’s efficacy in people with moderate to severe depression. That meant the drug worked better than electric shock therapy, an option when antidepressants fail. It was a breakthrough.

“I thought, you know, wow, this is something that I’m comfortable prescribing that could make a huge difference for my patients,” said Ross, who at the time was doing his residency in psychiatry at Massachusetts General Hospital.

But when he looked up the study, he discovered several oddities. For instance, the number of patients who experienced an adverse event differed by exactly one for 17 out of 18 single events like fatigue or bloating. That seemed unlikely to have occurred by chance. And all of the scores of statistical tests the authors had done turned out just the way they would have wanted, a dream that rarely comes true in biomedical sciences.

Scholar calls journal decision on ‘comfort women’ paper ‘rotten at the core’

The journal that published a hotly contested article by a professor at Harvard Law School arguing that Korean women forced into sexual slavery during World War II were willing prostitutes has reaffirmed a prior expression of concern over the paper, but stopped short of retracting the article.

However, the International Review of Law and Economics encourages readers of the article, by Mark Ramseyer, to “also consult the comments published in IRLE and in other venues for the broader historical perspective.”

Alexis Dudden, a professor of history at the University of Connecticut who has written extensively about Japan’s wartime system of military sexual slavery, called the statement “wishy-washy.”

“For the denialists, this is a victory,” she told Retraction Watch. “The IRLE decision is rotten at the core.”

Urologist blames Big Pharma as concerns mount over his research

With retractions piling up and more than a dozen expressions of concern now added to the list of his publishing woes, a urologist in Iran claims his research is being targeted by American drugmaker Johnson & Johnson.

Mohammad Reza Safarinejad, who offered no evidence for his allegations, says he retired from academia about 10 years ago and now runs a private clinic in Tehran. He has published scores of studies on topics ranging from treatments for premature ejaculation to saffron’s effect on semen, some of which have garnered hundreds of citations.

Starting in 2011, however, journals began pulling his papers over such issues as failure to verify data and inappropriate statistical analyses. The latest retraction, from August 2022, brings the tally up to 15, according to the Retraction Watch Database. And on January 10, The Journal of Urology issued expressions of concern for 14 of his papers, which have been cited a total of nearly 800 times, according to Clarivate’s Web of Science.

The journal states:

Ob-gyn who called criticism ‘racist’ and ‘hate speech’ earns retraction, several expressions of concern

There shouldn’t have been many differences between the women recruited for the three clinical trials: All of them gave birth at the same two Cairo hospitals over a period of less than three years, and all of them were treated to prevent or manage postpartum bleeding. Three samples from this pool of patients, Ben Mol felt, should have had largely similar baseline characteristics.

Yet, mysteriously, the women’s mean age and BMI varied markedly across the studies—from 25 to 34 years and from 25 to 29 kg/m2, respectively—as did the birthweight of their babies.

So the researcher turned data sleuth began digging. His worries only grew. Eventually, he would come to question the integrity of nearly two dozen randomized controlled trials led by Ahmed Maged, a professor of obstetrics and gynecology at Egypt’s top medical school, Kasr AlAiny at Cairo University.

Now, based in part on Mol’s findings, two journals published by Taylor & Francis have issued a retraction and nine expressions of concern for the following papers:

Japanese university asks surgeon to retract eight ‘fraudulent’ papers

An oral surgeon in Japan falsified images in several papers, granted authorship to whomever he saw fit and stored experimental data sloppily, according to an investigation by Showa University in Tokyo, where the physician was a lecturer at the time of the misconduct.

As a result of the findings, the university has recommended retracting eight papers by the surgeon, Masayasu Iwase, according to a translation commissioned by Retraction Watch of a December report from the committee that investigated the case.

The university also is discussing revoking the graduate degrees of two of Iwase’s former students whose dissertations were based on the “fraudulent” papers, the report explains.

Tadashi Hisamitsu, Showa’s president, wrote on the university’s website:

Police investigating after Polish journal accuses authors of ‘crime of plagiarism’

Polish police are investigating alleged plagiarism in a series of articles by a group of researchers at the University of Life Sciences in Lublin, Retraction Watch has learned.

A university commission also is looking into the allegations, which one of the authors told Retraction Watch had “greatly damaged” his career. While plagiarism is not usually considered a crime, it can be prosecuted under national copyright laws in Poland and elsewhere.

The alleged plagiarism was first discovered by a reviewer for Postępy Mikrobiologii – Advancements of Microbiology, a quarterly of the Polish Society of Microbiologists, said Radosław Stachowiak, who worked as the journal’s deputy editor-in-chief until the end of last year.

President of Iranian university in ‘serious breach of ethical standards’

The president of an Iranian university and a colleague appear to have published the same microelectronics paper twice, according to allegations seen by Retraction Watch.

The articles, by Bahram Azizollah Ganji and Kamran Delfan Hemmati of Babol Noshirvani University of Technology, deal with the design of a new capacitive accelerometer with a high dynamic range and sensitivity. Both appeared online in 2020, first in the Slovenia-based Journal of Microelectronics, Electronic Components and Materials and later in the higher-impact Springer journal Microsystem Technologies. The former version has yet to be cited, according to Clarivate’s Web of Science, while the latter has been cited twice.

The editors of Microsystem Technologies were made aware of the allegations on November 16 in an email that cited “significantly identical content” in the two papers. “Pretty much the entire introduction section and almost all figures are an exact copy from” the authors’ previous article, the email stated.
