Lack of conflict of interest disclosure undoes scoliosis study

scoliosisThe journal Scoliosis has retracted a 2012 paper by a pair of German spine doctors over what the editors have called a less-than-fully declared conflict of interest involving one of the authors.

That should be relatively straigtforward – but it’s not quite. Turns out the article does include a disclosure, although perhaps the information it contains was incomplete.

The article, “Soft braces in the treatment of Adolescent Idiopathic Scoliosis (AIS) – Review of the literature and description of a new approach,” was written by Hans-Rudolf Weiss and Mario Werkmenn. Weiss, it seems, has something of a pedigree in the field. According to this website, he practices the “Schroth method” of recurvature, a technique pioneered by his grandmother, Katharina Schroth. From the site: Continue reading Lack of conflict of interest disclosure undoes scoliosis study

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

Mislabeled sample leads to a chain reaction of physics retractions

physrevbTwo different teams of physicists have retracted papers from Physical Review B after realizing that a sample used in the paper published first — and which formed the basis of the second paper — was mislabeled.

Here’s the notice for the first paper, “s-wave superconductivity in barium-doped phenanthrene as revealed by specific-heat measurements,” by Jianjun Ying of the University of Science and Technology of China, Hefei, and colleagues: Continue reading Mislabeled sample leads to a chain reaction of physics retractions

Referencing failure (we mean, plagiarism) leads to retraction of water testing paper

evirmonassFrom the Not Saying What You Mean Files: Environmental Monitoring and Assessment has retracted a recent article by authors in Kuwait who appear to have plagiarized, although you couldn’t really tell from the notice.

The paper, “Detection of bacterial endotoxin in drinking tap and bottled water in Kuwait,” appeared in the December 2012 issue of the journal, which is a Springer title. Continue reading Referencing failure (we mean, plagiarism) leads to retraction of water testing paper

Two Journal of Bacteriology papers retracted for data duplication spanning five years

j bacteriolA group of bacteria researchers in Spain and Germany has lost two papers in the Journal of Bacteriology after the journal found evidence that they had reused figures.

The two notices, for “Heat Shock Proteome Analysis of Wild-Type Corynebacterium glutamicum ATCC 13032 and a Spontaneous Mutant Lacking GroEL1, a Dispensable Chaperone” and “Transcriptional Analysis of the groES-groEL1, groEL2, and dnaK genes in Corynebacterium glutamicum: Characterization of Heat Shock-Induced Promoters,” say the same thing: Continue reading Two Journal of Bacteriology papers retracted for data duplication spanning five years

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

A new record? 27-plus years later, a notice of redundant publication

royal society bA 1984 paper in Philosophical Transactions of The Royal Society B is now subject to a notice of redundant publication because a lot of it had been published in Cell the same year.

Whether 28 years — 27 years and 9 months, to be precise — is any kind of official record is unclear, since we haven’t really kept track of notices of redundant publication. It would, however, beat the record for longest time between publication and retraction, 27 years and one month.

Here’s the notice, which ran in September of last year but just came to our attention: Continue reading A new record? 27-plus years later, a notice of redundant publication

Double-dipping leads to removal of petroleum research paper

pst journalcoverIranian scientists have lost one of two articles they submitted — and published — simultaneously to different journals. Watch as confusion ensues.

The retracted paper, “Permeability Estimation of a Reservoir Based on Neural Networks Coupled with Genetic Algorithms,” appeared online in August 2011  in Petroleum Science and Technology, a Taylor & Francis journal. According to the liner notes, the paper had been received on January 15, 2010 and accepted a few weeks later. It has been cited once since, according to Thomson Scientific’s Web of Knowledge, by its authors, in a paper published in the same journal.

Meanwhile, in August 2011 the authors (minus one name) also published “Evolving neural network using real coded genetic algorithm for permeability estimation of the reservoir,”  in Expert Systems With Applications, an Elsevier title.

The standing paper — which has been cited seven times — now carries the following erratum notice (dated far into the future, September 2013): Continue reading Double-dipping leads to removal of petroleum research paper

Paper by Bristol-Myers Squibb researchers retracted for “unsolved legal reasons”
