Image highjinx lead to retraction of hot pepper paper

pcp 913coverYou might be forgiven for thinking that the editors were describing a bad relationship rather than a paper gone wrong, the journal of Plant and Cell Physiology is retracting a 2004 article by Korean researchers who “manipulated and repeatedly used” micrographs.

The article, “Ornithine Decarboxylase Gene (CaODC1) is Specifically Induced during TMV-mediated but Salicylate-independent Resistant Response in Hot Pepper,” which appeared a s a short communication in the journal, came from the lab of Kyung-Hee Paek at Korea University.

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”

“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.

Scientists doing the right thing: Malfunctioning lab equipment leads to retraction of neuroscience paper

cerebral cortexFor the second time inside of a week, we come to praise scientists who did the right thing when they realized their lab equipment or reagents weren’t performing as expected.

Here’s the retraction of a 2011 paper in Cerebral Cortex: Continue reading Scientists doing the right thing: Malfunctioning lab equipment leads to retraction of neuroscience paper

Environmental scientists call for retraction of oil industry-funded paper on benzene exposure

carcinogenesis 13A paper suggesting that scientists may want to rethink what levels of benzene are carcinogenic has led to a sharp exchange in the journal that originally published it.

In 2006, Stephen Rappaport, of UNC-Chapel Hill, and colleagues, published a paper that began by saying that benzene

is an important industrial chemical that is also emitted into the air from gasoline, engine exhausts and combustion of organic materials (including cigarette smoke) (1,2). Occupational exposures to benzene at air levels greater than ∼10 p.p.m., have long been linked to hematotoxicity and to acute myelogenous leukemia (3–5). A recent report of hematotoxic effects in workers exposed to benzene <1 p.p.m. (6) has raised additional concerns regarding the health consequences of low exposures to this contaminant.

The authors conclude: Continue reading Environmental scientists call for retraction of oil industry-funded paper on benzene exposure

Study of blood pressure drug valsartan retracted

matsubaraHiroaki Matsubara, a prominent cardiologist with five Expressions of Concern and two retractions for his CV, has another retraction.

As Larry Husten, who first reported the retraction at Forbes, notes, the notice for 2009’s “Effects of valsartan on morbidity and mortality in uncontrolled hypertensive patients with high cardiovascular risks: KYOTO HEART Study,” which appeared in the European Heart Journal, says very little: Continue reading Study of blood pressure drug valsartan retracted

Royal jelly figure flushed: Author removes figure from 2002 paper

j biochemRoyal jelly — “the goo that sustains honeybees destined for royalty” and is touted dubiously for everything “from youthful skin to virility,” as Nature put it — is apparently a hot research topic. So when a Retraction Watch tipster sent us a corrigendum that seemed to have done something we hadn’t seen before — retract a single figure, without saying why — we figured we’d check it out.

Here’s the text of the corrigendum: Continue reading Royal jelly figure flushed: Author removes figure from 2002 paper

ORI investigating University of Florida ob-gyn researcher accused of misconduct

A prominent researcher at the University of Florida is under federal investigation for research misconduct and has lost at least one paper as a result of the fraud.

The researcher, Nasser Chegini, was a professor of obstetrics and gynecology at the U of Florida until about six months ago, when he retired, according to the chair’s office. Nasser has received at least $4 million in federal grant funding, according to the university.

The retracted paper, “MicroRNA 21: response to hormonal therapies and regulatory function in leiomyoma, transformed leiomyoma and leiomyosarcoma cells,” was published in 2010 by Molecular Human Reproduction. The authors were Qun Pan and Xiaoping Luo and Chegini.

Authors retract prostate cancer-grape seed compound paper for figure presentation error

University of Alabama researchers have retracted a paper claiming that a grape skin seed compound might have anti-prostate cancer effects.
