Third retraction for Karel Bezouška, of lab break-in fame

bichaw_v052i049.inddWe’ve found a third retraction for Karel Bezouška, the Czech scientist, who, as we reported this summer, broke into a lab in an attempt to tamper with experiments trying to replicate his own falsified data.

The article, “Molecular Characterization of Binding of Calcium and Carbohydrates by an Early Activation Antigen of Lymphocytes CD69,” had appeared in 2003 in Biochemistry. and has been cited 29 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction notice: Continue reading Third retraction for Karel Bezouška, of lab break-in fame

Okay, so it’s not quite Kafka, but a group of forensic geneticists from Prague’s Charles University has lost a paper in Folia Biologica (a journal from that famed institution where Kafka studied) over what appears to be a rather Byzantine dispute about authorship and the quality of the data.

The 2010 article, “DNA analysis of ancient skeletal remains” was written by a trio of authors from Charles University’s Department of Anthropology and Human Genetics. According to its abstract: Continue reading Author stalemate in Czech DNA paper leads to retraction

Second retraction for Czech fraudster Bezouska, who broke into lab

bmc biotechEarlier this month we wrote about the retraction by Nature of a 19-year-old paper by Karel Bezouska, a former star researcher at Prague’s Charles University whose “dangerous and irresponsible deviations” from acceptable practice went as far as tampering with refrigerated samples to cover his tracks.

BMC Biotechnology has retracted another Bezouska paper, this one from 2011. He’s the second author on the article, titled “Heterologous expression, purification and characterization of nitrilase from Aspergillus niger K10.”

Researchers get a mulligan: JBC paper withdrawn sans explanation

jbc july 2013A group of authors has withdrawn a paper from the Journal of Biological Chemistry (JBC), but readers won’t know why.

The paper, “Static High-Gradient Magnetic Fields Activate Transient Receptor Potential Vanilloid 4 (TRPV4) Ion Channels Enabling Remote Control of Cell Function,” whose corresponding author is Thomas Simmet of Ulm University, appeared online on June 11. Since June 24, the PDF of the paper has been stamped: Continue reading Researchers get a mulligan: JBC paper withdrawn sans explanation

Retraction of 19-year-old Nature paper reveals hidden cameras, lab break-in, evidence tampering

nature bezouskaWe’ve often found that when some authors refuse to sign retraction notices, there’s a much bigger story than terse notices let on. And a retraction in this week’s Nature of a 19-year-old paper is a shining example of that.

Here’s the brief notice for “Oligosaccharide ligands for NKR-P1 protein activate NK cells and cytotoxicity,” a 1994 paper by researchers from the UK and the Czech Republic that had already been subject to a 1996 correction: Continue reading Retraction of 19-year-old Nature paper reveals hidden cameras, lab break-in, evidence tampering

Hip, hip, retract! Cobalt poisoning case study pulled as duplicate

hipinternationalHip International has retracted a case study for duplication. (We apologize for the partial duplication of a headline for an earlier post about this journal, which told readers that “Similar cases will be referred to retractionwatch.”)

The article was titled “Chronic intoxication with cobalt following revision total hip arthroplasty,” and it appeared online ahead of print. Cobalt toxicity associated with metal-on-metal replacement hips has been raised as a potential adverse effect from the devices.
