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:

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

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”

“Ephemeral nature” of samples — and co-author — leads to ninth Jesús Lemus retraction

j app ecolJesús Lemus — the veterinary researcher whose work colleagues have had trouble verifying, including being unable to confirm the identity of one of his co-authors — has notched his ninth retraction.

It’s a clear and comprehensive notice, from the Journal of Applied Ecology, despite the bizarre nature of the case: Continue reading “Ephemeral nature” of samples — and co-author — leads to ninth Jesús Lemus retraction

Don’t feel so bad, The Aging Male: It happens to lots of journals

aging maleThe Aging Male (the journal, not the demographic) is retracting a 2013 paper by a group of Chinese researchers who’d published the same work — more or less — in a Chinese title.

The article, “Testosterone therapy improves psychological distress and health-related quality of life in Chinese men with symptomatic late-onset hypogonadism patients,” came from a group at Peking University People’s Hospital, in Beijing.

But as the retraction notice explains: Continue reading Don’t feel so bad, The Aging Male: It happens to lots of journals

Paper on partially entangled states retracted for partially entangling authors

phys rev aA paper on partially entangled states seems to have fallen victim to a confusing entanglement of authors and studies.

Here’s the notice for the paper, “Optimal quantum communication using multiparticle partially entangled states,” by Atul Kumar, Satyabrata Adhikari, Subhashish Banerjee, and Sovik Roy: Continue reading Paper on partially entangled states retracted for partially entangling authors

A retraction with “serious consequences to wheat production”

pmbrChinese researchers have had a 2012 paper in Plant Molecular Biology Reporter on genetically modified wheat retracted, in a notice that cites fraud.

The article, “Isolation and Functional Characterization of an Antifreeze Protein Gene, TaAFPIII, from Wheat (Triticum aestivum),” came from the same group we wrote about in April 2012 when they retracted a paper from Acta Biochimica et Biophysica Sinica, also about genetically altered wheat.

At the time, the authors said they were pulling the other paper because they were having trouble replicating their findings. That now seems accurate, but not entirely complete.

As the new retraction notice states: Continue reading A retraction with “serious consequences to wheat production”

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.

As the retraction notice explains: Continue reading “Technical but fundamental errors” lead to retraction of brain tumor paper

Update: Microbiologists face two more retractions for Northern blot problems

microbiologyWe have an update on a case we reported last week involving four papers in two different journals. The Journal of Bacteriology retracted two papers by Carlos Barreiro and colleagues, in notices that referred to the fact that

…identical bands for the 16S rRNA probe controls in the Northern blots were reported to correspond to experiments using different strains and experimental conditions in articles published in this journal and in Microbiology over a period of 5 years…

We checked with the editor of Microbiology, Agnes Fouet, who tells us: Continue reading Update: Microbiologists face two more retractions for Northern blot problems
