A journal has added expressions of concern (EOCs) to four papers about diabetes, including one co-authored by an author who previously sued a different journal when it took a similar action on his papers.
The Journal of Physiology flagged the papers after an investigation “could not rule out the possibility” that they contained duplicated Western blots. Though the three other papers do not include Mario Saad on their author list, he plays a role: The papers include blots duplicated from other papers of Saad’s. And they reveal that Saad may have published those blots multiple times in his own work.
Authors have retracted three papers from the Journal of Physiology because they contained “falsified or fabricated data.”
The papers, which address calcium signaling in heart muscle cells, are among the six pegged for retraction after an Office of Research Integrity (ORI) investigation into one of the authors, Igor Dzhura, formerly of Vanderbilt University. The ORI found that Dzhura had committed an enormous amount of fraud, involving dozens of faked images and more.
A former Vanderbilt University biomedical engineer committed fraud on a massive scale, according to a new Office of Research Integrity (ORI) report.
Igor Dzhura is banned from receiving federal funding for three years, and is retracting six papers, which have been cited more than 500 times. Since leaving Vanderbilt, he has worked at SUNY Upstate Medical University, and now works at Novartis.
The scientific literature has started to hint at the fallout of a case of potential fraud in Denmark. As Nature reported in January:
A high-profile neuroscientist in Denmark has resigned after facing allegations that she committed research misconduct and misspent grant money. Meanwhile, the administration at the university where she worked has been accused of ignoring her alleged misdeeds for the better part of a decade.
Milena Penkowa, a 37-year-old researcher who was lauded in 2009 by the Danish science ministry, denies all the accusations against her and stands by her work, but left her post as a full professor at the University of Copenhagen in December.
