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

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:

Cardiology journals retract five Matsubara studies

matsubaraThe American Heart Association (AHA) is retracting five studies by Hiroaki Matsubara, a former Kyoto Prefectural University cardiology researcher, that it had subjected to an expression of concern last year.

Here’s the notice: Continue reading Cardiology journals retract five Matsubara studies

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:

Tenth retraction appears for Jesús Lemus, this one in PLOS ONE

plos oneJust two days ago, we covered the ninth retraction for Jesús Lemus, “the veterinary researcher whose work colleagues have had trouble verifying, including being unable to confirm the identity of one of his co-authors.” And already another of his retractions has appeared in one of our daily alerts.

This one appears in PLOS ONE, for “Infectious Offspring: How Birds Acquire and Transmit an Avian Polyomavirus in the Wild:” Continue reading Tenth retraction appears for Jesús Lemus, this one in PLOS ONE

Doing the right thing: Psychology researchers retract after realizing data “were not analyzed properly”

cerebral cortexAmid an ongoing investigation, a group of psychology researchers at the University of Leuven (KU Leuven) in Belgium have taken a painful decision to retract a paper now that they’ve realized there were serious problems with one aspect of the work.

Here’s the notice for “The Emergence of Orthographic Word Representations in the Brain: Evaluating a Neural Shape-Based Framework Using fMRI and the HMAX Model,” by Wouter Braet, Jonas Kubilius, Johan Wagemans, and Hans P. Op de Beeck: Continue reading Doing the right thing: Psychology researchers retract after realizing data “were not analyzed properly”

Not your data: Nursing paper retracted for misuse of findings

nurse education todayWe’re all for research on improving communication and collaboration among colleagues. But we trust that the experts know what they’re doing. You can see where this is going.

The journal Nurse Education Today has retracted a 2012 article, “Interprofessional learning in acute care: Developing a theoretical framework,” by a UK scholar because, how shall we put it, he might need a few lessons in interprofessionalism.

The retraction notice explains it neatly: Continue reading Not your data: Nursing paper retracted for misuse of findings

“Technical but fundamental errors” lead to retraction of brain tumor paper

neuro-oncologyThe journal Neuro-Oncology has retracted a 2011 paper by a group of researchers in Japan who had purported to find a genetic mechanism for how fluorescence can be used to diagnose certain brain tumors.

The paper, “Enhanced expression of coproporphyrinogen oxidase in malignant brain tumors: CPOX expression and 5-ALA–induced fluorescence,” reported measurements using quantitative real-time (qRT)-PCR.
