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:

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.

BioMed Central retracts study it published twice while acquiring journal

jdmdYesterday, we wrote about the retraction of a paper that ended up published despite the fact that peer reviewers had recommended rejecting it. Today, we have the (short) tale of a paper retracted because the publisher posted it a second time while they were buying acquiring the journal where it appeared.

Here’s the notice for “The association between depression, socio-economic factors and dietary intake in mothers having primary school children living in Rey, South of Tehran, Iran,” published in the Journal of Diabetes & Metabolic Diseases: Continue reading BioMed Central retracts study it published twice while acquiring journal

Nanotech researcher SK Sahoo notches fifth retraction

acta biomaterialiaNanotech researcher SK Sahoo, whom as we reported in February lost four papers from Acta Biomaterialia for what the journal called “highly unethical practices,” has actually retracted five papers from that journal.

According to a notice for “Enhanced cellular uptake and in vivo pharmacokinetics of rapamycin loaded cubic phase nanoparticles for cancer therapy” that appears in the June issue along with the other four: Continue reading Nanotech researcher SK Sahoo notches fifth retraction

Madoff retracts scientific paper

dcrectNo, not that Madoff.

We’re talking about Robert Madoff, editor of Diseases of the Colon & Rectum. His journal is pulling a 2012 paper by a group of authors in Spain who seem to have been unable to back up their findings when they were found to contain errors.

The article, “Perianal versus endoanal application of glyceryl trinitrate 0.4% ointment in the treatment of chronic anal fissure: results of a randomized controlled trial. Is this the solution to the headaches?” looked at what evidently is a significant side effect of nitroglycerin treatment for anal fissures: headaches. According to the abstract:

Failure to reproduce experiments, errors lead to retraction of pancreatic cancer paper

lab investThe authors of a paper in Laboratory Investigation have retracted it after they were unable to “reproduce key experiments,” and discovered “several minor errors.”

Here’s the retraction notice for “Slug enhances invasion ability of pancreatic cancer cells through upregulation of matrix metalloproteinase-9 and actin cytoskeleton remodeling,” by Liqun Wu and colleagues of The Affiliated Hospital of Medical College, QingDao University, in China’s Shan Dong Province: Continue reading Failure to reproduce experiments, errors lead to retraction of pancreatic cancer paper
