Second retraction for Czech fraudster Bezouska, who broke into lab

bmc biotechEarlier this month we wrote about the retraction by Nature of a 19-year-old paper by Karel Bezouska, a former star researcher at Prague’s Charles University whose “dangerous and irresponsible deviations” from acceptable practice went as far as tampering with refrigerated samples to cover his tracks.

BMC Biotechnology has retracted another Bezouska paper, this one from 2011. He’s the second author on the article, titled “Heterologous expression, purification and characterization of nitrilase from Aspergillus niger K10.”

JCI paper retracted for duplicated panels after authors can’t provide original data

jciSo how long do researchers have to keep records of experiments?

We had that question while reading the retraction notice for a 2007 paper in the Journal of Clinical Investigation: Continue reading JCI paper retracted for duplicated panels after authors can’t provide original data

Researchers get a mulligan: JBC paper withdrawn sans explanation

jbc july 2013A group of authors has withdrawn a paper from the Journal of Biological Chemistry (JBC), but readers won’t know why.

The paper, “Static High-Gradient Magnetic Fields Activate Transient Receptor Potential Vanilloid 4 (TRPV4) Ion Channels Enabling Remote Control of Cell Function,” whose corresponding author is Thomas Simmet of Ulm University, appeared online on June 11. Since June 24, the PDF of the paper has been stamped: Continue reading Researchers get a mulligan: JBC paper withdrawn sans explanation

Former Duke researcher charged with embezzlement has a paper retracted

j app physA new retraction notice in the Journal of Applied Physiology gives only a hint at the problems in the paper, but what it does say has led us to a story about one of its co-authors.

Here’s the notice, from a team at Duke: Continue reading Former Duke researcher charged with embezzlement has a paper retracted

Cell line mixup causes retraction of paper on blood vessel damage

britjournnutWe’ve written before about retractions for cell lines that turn out not to be what researchers thought they were. In a few cases, that has involved contamination by HeLa cells, named for Henrietta Lacks. Today, we note the retraction of a paper whose authors, from Taiwan, thought they were using human muscle cells that line blood vessels when they were actually studying such cells from rat embryos.

Here’s the notice in the British Journal of Nutrition for “Molecular mechanism of green microalgae, Dunaliella salina, involved in attenuating balloon injury-induced neointimal formation”: Continue reading Cell line mixup causes retraction of paper on blood vessel damage

A masterbatch: More polymer retractions, gerontology journal lifts paywall, Microbiology notices appear

Our mothers told us that if we used the masterbatch process, we’d go blind. And what better way to gather some updates to recent posts than to include one that involves said masterbatch process?

First, a retraction John Spevacek noticed when he tried clicking on the link in a Journal of Applied Polymer Science retraction we’d covered: Continue reading A masterbatch: More polymer retractions, gerontology journal lifts paywall, Microbiology notices appear

Lost from translation(al) medicine: Publisher error leads to retraction

jrntransmedA technical hiccup led the Journal of Translational Medicine to double publish a 2012 paper by a pair of researchers from China and the United States, leading to a retraction.

The article is/was titled “Opportunities and challenges of disease biomarkers: a new section in the journal of translational medicine,” and it was written by Xiangdong Wang and Peter Ward — both members of the journal’s editorial board. It appeared in the Nov. 7, 2012 issue of the JTM. And it appeared less than a month later, on Dec. 5.

A mega-correction for Rui Curi, whose lawyers threatened to sue Science-Fraud.org

plos oneA Brazilian researcher whose legal threats helped lead to the shutdown of Science-Fraud.org and who has had two papers retracted has had to correct another paper.

The fourth correction for Rui Curi — and we’d call it a mega-correction — is of a paper in PLOS ONE. Curi is the fourth out of 11 authors; someone named Tania Pithon-Curi is the final author:

French journal retracts nanomedicine paper for ethics violations, more

bioladjcoverThe French journal Biologie Aujourd’hui — Biology Today — has retracted an article it published earlier this year after learning of ethics violations,  authorship issues with the paper and a problematic image.

The article, titled “Utilisation de dendrimères pour une nanomédecine innovatrice,” or “Using dendrimers for an innovative nanomedicine,” was written by Jean Pierre Majoral of the Laboratoire de Chimie de Coordination in Toulouse. (We haven’t been able to get our virtual hands on the paper yet.)

According to the retraction notice, which in fact says “withdrawal notice“:  Continue reading French journal retracts nanomedicine paper for ethics violations, more

Kidney International paper retracted after lab records “were improperly filed”

kidney intA group of University of California, Davis kidney researchers have retracted a paper after being unable to verify key parts of it.

Here’s the detailed retraction notice for “Proteinuria decreases tissue lipoprotein receptor levels resulting in altered lipoprotein structure and increasing lipid levels,” published by Limin Wang, George Kaysen, and colleagues in Kidney International last July: Continue reading Kidney International paper retracted after lab records “were improperly filed”
