We know why the caged dimers sing: They’re being retracted

jacsat_v135i024.inddHere’s a good example of a retraction done the right way (we think).

The Journal of the American Chemical Society has retracted — at the behest of the principal investigator  — a 2008 article by a group of researchers whose subsequent studies undermined their confidence in the validity of their initial findings.

The article was titled “Cooperative melting in caged dimers of rigid small molecule DNA-hybrids,” and it came from the lab of SonBinh Nguyen, of Northwestern University. As the paper’s abstract stated:

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 fifth retraction for former Pitt and Hopkins oncology researcher Getzenberg

ccrA cancer researcher whose work was the subject of a lawsuit has retracted his fifth paper, this one from 2004.

Robert Getzenberg, formerly of the University of Pittsburgh and Johns Hopkins, has had two papers on prostate cancer biomarkers retracted, and two on colon cancer. The newly retracted paper is about a potential bladder cancer biomarker.

Here’s the notice from Clinical Cancer Research: Continue reading A fifth retraction for former Pitt and Hopkins oncology researcher Getzenberg

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”

A double-bill from Digestive Diseases and Sciences, both for regurgitation — aka duplication

ddsComing back up?

Digestive Diseases and Sciences has retracted two papers for duplication.

The first paper, “Membrane-Bound Mucins and Mucin Terminal Glycans Expression in Idiopathic or Helicobacter pylori, NSAID Associated Peptic Ulcers,” was published in October 2012 by a group from Israel and the United States. It found that:

Cytoplasmic MUC17 staining was significantly decreased in the cases with idiopathic ulcer. The opposite was demonstrated for MUC1. This observation might be important, since different mucins with altered sialylation patterns likely differ in their protection efficiency against acid and pepsin.

But, as the retraction notice suggests, that much had been found before: Continue reading A double-bill from Digestive Diseases and Sciences, both for regurgitation — aka duplication

Quorum sensing paper retracted when new study suggests compounds weren’t what they seemed

plos oneThe authors of a paper on quorum sensing — in simple terms, how bacteria “talk” to one another — have retracted it after another group’s findings led them to discover that the mixture they used weren’t what they thought.

The refreshingly detailed retraction notice in PLOS ONE explains: Continue reading Quorum sensing paper retracted when new study suggests compounds weren’t what they seemed

Amid a legal dispute, journal downgrades a retraction to an expression of concern

cellcyclecoverThe journal Cell Cycle is expressing a “note” of concern about a 2012 paper by a former researcher at the University of Minnesota, who has claimed that her mentor at the institution was violating her copyright. It turns out the journal had briefly retracted the paper, but reversed itself with the expression of concern — a curious about-face that, in our experience, often indicates the work of lawyers.

That seems to be the case here, too.

The article, “Chalcone-based small-molecule inhibitors attenuate malignant phenotype via targeting deubiquitinating enzymes,” was already the subject of an erratum, available here:

Cell reviewing allegations of image reuse in human embryonic stem cell cloning paper

cell cloningCell is looking into whether the authors of a widely hailed study published last week claiming to have turned human skin cells into embryonic stem cells manipulated images inappropriately, Retraction Watch has learned.

The potential image problems came to light on PubPeer, a site designed to allow for post-publication peer review. A commenter, identified as Peer1, identified “several examples of image reuse which might be of interest to PubPeer members and readers:” Continue reading Cell reviewing allegations of image reuse in human embryonic stem cell cloning paper

Journal expresses concern over flawed multiple sclerosis treatment guideline

neurology may13coverThe journal Neurology has issued an Expression of Concern over recommendations it published earlier this year regarding the treatment of multiple sclerosis.

The journal’s website received multiple comments from clinicians expressing their own concern about the flawed recommendation, which was published as part of a paper titled “The American Academy of Neurology’s Top Five Choosing Wisely recommendations.” The problematic item was number 4: Continue reading Journal expresses concern over flawed multiple sclerosis treatment guideline
