The 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.
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: Read the rest of this entry »
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: Read the rest of this entry »
Royal 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.
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.
Here’s the notice for “Proanthocyanidins from grape seeds inhibit expression of matrix metalloproteinases in human prostate carcinoma cells, which is associated with the inhibition of activation of MAPK and NFκB”: Read the rest of this entry »
Family Practice has retracted a 2009 review article on diabetes whose author had published a similar — in spots identical — paper two years earlier in another journal. We think the notice is nine-tenths solid, but there’s a part at the end that raises an important question about how much, or little, editors should do to accommodate the embarrassments of their authors.
Here’s our attempt at a summary: Jacques Donnez, chair of Catholic University of Louvain’s (UCL) gynecology department, and colleagues published two studies in Human Reproduction in 2010. One study claimed to show that a woman had given birth after undergoing chemotherapy for severe sickle cell disease and then getting an ovarian transplant from her sister.
The other of those studies, the authors noted, confirmed “data published earlier as a case report” in 2007. That case report of a woman with another type of anemia — the pregnancy only went as far as an embryo, which did not survive — garnered a good deal of attention, because, as New Scientist reported: Read the rest of this entry »
The European Journal of Cardiothoracic Surgery has retracted a 2007 article by Chinese researchers after the senior author decided he liked the data so nice he’d publish them twice. And he appears to have done so without the knowledge of the corresponding author.
