A notice on the paper, “Autologous human cardiac stem cells transplantation for the treatment of ischaemic cardiomyopathy: first study of human-induced pluripotent stem (iPS) cell-derived cardiomyocytes transplantation,” which appeared in BMJ Case Reports, now reads: Continue reading Dubious stem cell researcher Moriguchi notches temporary withdrawal, notice of redundant publication

Authors withdraw already-corrected JBC paper questioned on PubPeer

jbc 8-9-13An assistant professor of neuroscience at Tufts has withdrawn a paper published last year after one round of corrections wasn’t enough to fix all of the study’s problems.

The study, “Sirtuin 2 (SIRT2) enhances 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced nigrostriatal damage via deacetylating forkhead box O3a (Foxo3a) and activating Bim protein,” by Gizem Donmez and colleagues, had already been subject to an extensive correction in May: Continue reading Authors withdraw already-corrected JBC paper questioned on PubPeer

The Office of Research Integrity (ORI) has sanctioned an assistant professor of dermatology at Case Western Reserve University in Cleveland for plagiarizing from a grant application she was reviewing — which feels like a scientific version of insider trading — and a number of published papers.

According to the ORI’s findings, Pratima Karnik Continue reading Case Western dermatology department hit with second ORI sanction within 6 months

A sad postscript: Paper by deceased researcher retracted

cancer researchIt was the last study ever published from prominent scientist Gerd Maul’s lab. And now it’s been retracted.

Maul was a highly cited cell biologist, with 30 papers cited at least 100 times, according to Thomson Scientific’s Web of Knowledge. He was also a well-known sculptor. When he died in 2010, he had a paper under submission at Cancer Research, which was published late that year.

This year, however, his co-authors found problems with the study. And as the notice — one of the most detailed we’ve ever seen — explains: Continue reading A sad postscript: Paper by deceased researcher retracted

University of Utah finds former faculty member guilty of misconduct because of “reckless disregard”

utahSince last May, we’ve been reporting on a case at the University of Utah involving two retractions and two corrections. When the story first broke, the lab blamed a former worker for inappropriately removing data from the premises, and the university has been investigating. Last month, we reported that Ivana De Domenico, the junior faculty member who was first author on those papers, had left the university, and that senior author Jerry Kaplan had retired.

But the problems went beyond the four papers we reported on, as the Salt Lake Tribune reported on Friday. In a 9-page report provided to the Tribune, the panel overseeing the investigation details its examination of 11 papers. This is the first of six findings: Continue reading University of Utah finds former faculty member guilty of misconduct because of “reckless disregard”
