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

Authors hit for image manipulation cycle, but don’t worry, they’ll resubmit retracted paper

j virologyRegrets were had, mistakes were made, but gosh-darn-it, they’re gonna resubmit that retracted paper in the future.

Such is the message from a retraction of “Tsg101 Interacts with Herpes Simplex Virus 1 VP1/2 and Is a Substrate of VP1/2 Ubiquitin-Specific Protease Domain Activity,” from Italian virologists who admitted to copying and pasting their way into the Journal of Virology: Continue reading Authors hit for image manipulation cycle, but don’t worry, they’ll resubmit retracted paper

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

A partial retraction appears for former Salzburg crystallographer who admitted misconduct

j imm april 2013A paper by a crystallographer fired from his university for misconduct has been partially retracted.

Last year, we covered the case of Robert Schwarzenbacher, formerly of Salzburg University. Schwarzenbacher had provided the crystallographic data for a paper in the Journal of Immunology, but those results raised questions with another crystallographer and prompted an investigation by the university.  Schwarzenbacher admitted he’d committed misconduct, although he recanted at one point, and was eventually fired.

Now, the authors have retracted the crystallographic data from the Journal of Immunology paper. Here’s the partial retraction, which is listed as a correction:

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:

Author break prompts retraction of bone protein paper

ejpcoverThe European Journal of Pharmacology has — against its will, it would seem — retracted a 2012 paper by a group of Chinese heart researchers embroiled in a what appears to be a rather messy authorship dispute.

The article, “The effect of alendronate on the expression of osteopontin and osteoprotegerin in calcified aortic tissue of the rat,”  came from the Institute of Cardiovascular Disease at Tongji Hospital, part of of Huazhong University of Science and Technology.

As the retraction notice states:

Dodgy figure in cord blood paper prompts Expression of Concern in oncology journal

cmionccoverThe editor of Clinical Medicine Insights: Oncology has issued an Expression of Concern over a 2008 paper by a group of authors in China after identifying “flaws” in one of the figures.

The article, “Exvivo experiments of human ovarian cancer ascites-derived exosomes presented by dendritic cells derived from umbilical cord blood for immunotherapy treatment,” purported to show that:

tumor-specific antigens present on exosomes can be presented by DCs [dendritic cells] derived from unrelated umbilical cord blood to induce tumor specific cytotoxicity and this may represent as a novel immunotherapy for ovarian cancer.

But according to William C. S. Cho, editor of the journal, there’s reason to doubt the conclusions. As the notice explains:
