Nanoparticle paper earns retraction for lack of reproducibility

issue 1 - RSC Advances_2012.inddA nanoparticle article published earlier this year has been retracted by RSC Advances for lack of reproducibility, although we haven’t been able to get more details about what happened.

Here’s the notice for “Sonochemical synthesis of poly(methyl methacrylate) core–surfactin shell nanoparticles for recyclable removal of heavy metal ions and its cytotoxicity” (freely available but requires sign-in): Continue reading Nanoparticle paper earns retraction for lack of reproducibility

“Conscious fabrication” leads to retraction of diabetes study

diabetcoverDiabetologia has retracted a 2011 meeting abstract from a group in Sweden, indicating that the second author has been found guilty of research misconduct — a charge the scientist denies.

The abstract, “Reduced syntaxin-5 in skeletal muscle of patients with type 2 diabetes is linked to increased diacylglycerol, activation of PKCtheta and impaired insulin signalling,” was presented at the annual meeting of the European Association of the Study of Diabetes. The first author was Kurt Højlund, who now is at the University of Southern Denmark. The second author was Pontus Boström, of the Karolinska Institutet.

In June, we reported on a retraction in Current Biology that came after a number of PubPeer commenters suggested that the authors had engaged in figure manipulation, memorably comparing watching the published videos to playing the old-school arcade game “Space Invaders.”

Now a second paper from the same team has been retracted from Biology Open after the authors “were unable to repeat the results.” The journal was unable to get in touch with first author Livana Soetedio, whom the University of Illinois at Chicago found had fabricated the data and images in both publications.

Here’s the notice for “Targeting of vasoactive intestinal peptide receptor 2, VPAC2, a secretin family G-protein coupled receptor, to primary cilia”: Continue reading Second retraction appears for arcade game-like image manipulation

Leukemia paper retracted for plagiarism — 18 years later

BTER_116_1_cvr_spine.p65Nearly two decades after a Polish researcher plagiarized the work of a Turkish team, her theft has been exposed and the paper retracted.

According to an article in Polish-language paper Gazeta Wyborcza, Jolanta Rzymowska of the Medical University of Lublin was the subject of two disciplinary hearings, the first in February 2014, following the discovery of her plagiarism by well-known Polish fraud hunter Marek Wronski. It was determined that her 1996 paper contained word-for-word text from a paper by a team at the University of Ankara.

Ultimately, Rzymowska was given an official reprimand, rather than any harsher disciplinary action, because she copied descriptions rather than results. From a Google translation of the article: Continue reading Leukemia paper retracted for plagiarism — 18 years later

A paper by a former postdoc at MD Anderson Cancer Center who “admitted to knowingly and intentionally falsifying” a figure has been retracted.

In August, the Office of Research Integrity announced that it had sanctioned Jun Fu for faking data in a study of the results of a mouse study of NVP-HSP990, a Novartis compound designed to fight brain tumors. Here’s the notice for the study in question, published in Cancer Research:

Paper on circulating tumor cells taken out of circulation after lab error

medical oncologyA group of researchers at the Guangdong Academy of Medical Sciences in Guangzhou, China have retracted a paper that came out of a clinical trial on transarterial chemoembolization, a targeted kind of chemotherapy.

According to the notice, one of the authors mixed up the control samples with the clinical samples, and “could not recall which samples were in the wrong group.” The paper hasn’t yet been cited, according to Thomson Scientific’s Web of Knowledge.

Univ.: No misconduct, but “poor research practice” in mgt prof’s work now subject to 7 retractions

The Leadership Quarterly has retracted a trio of papers by Frederick Walumbwa, an “ethical leadership” guru at Florida International University, whose work has come under scrutiny for flawed methodology. And another journal  has pulled one of his articles for similar reasons. That brings his count – as far as we can tell — to seven retractions and a mega-correction.

Meanwhile, Arizona State University, Walumbwa’s former employer, has found

that the preponderance of evidence does not support the charge of research misconduct by Dr. Walumbwa…

but that he engaged in “poor research practice.”

The bottom line, according to the Leadership Quarterly, which first announced problems with the articles in February:
