Karel Bezouška, who broke into lab to tamper with investigation, has JACS paper retracted

Karel Bezouška, who, as we noted last year “broke into a lab refrigerator so he could tamper with samples being used to try to replicate the experiments during the investigation,” has had his fourth paper retracted. Here’s the notice, for “Synthesis of Multivalent Glycoconjugates Containing the Immunoactive LELTE Peptide: Effect of Glycosylation on Cellular Activation … Continue reading Karel Bezouška, who broke into lab to tamper with investigation, has JACS paper retracted

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

We’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 … Continue reading Third retraction for Karel Bezouška, of lab break-in fame

Second retraction for Czech fraudster Bezouska, who broke into lab

Earlier 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 … Continue reading Second retraction for Czech fraudster Bezouska, who broke into lab

Two more retractions bring lab break-in biochemist up to eleven

Karel Bezouška, the Czech biochemist who was caught on hidden camera breaking into a lab fridge to fake results, has turned it up to eleven with two new retractions. Both retractions appeared in Biochemical and Biophysical Research Communications, one in October 2014 and one in January 2015.  His story began two decades ago in 1994, when he published … Continue reading Two more retractions bring lab break-in biochemist up to eleven

Nature, facing “considerable rise” in retractions, blames lawyers for opaque and delayed notices

Nature, as we and others have noticed, has had what Paul Knoepfler referred to as a “torrent” of retractions in the past two years. That torrent — 13 research papers — has prompted a welcome and soul-searching editorial, as it did in 2010 when the journal had what it called an “unusually large number” of … Continue reading Nature, facing “considerable rise” in retractions, blames lawyers for opaque and delayed notices

Researcher who broke into lab up to nine retractions

Karel Bezouška, a researcher who broke into a lab refrigerator to tamper with an investigation into his work, has nine retractions. Here’s the retraction notice in Biochemistry for 2010’s “Cooperation between Subunits Is Essential for High-Affinity Binding of N-Acetyl-d-hexosamines to Dimeric Soluble and Dimeric Cellular Forms of Human CD69:”

Researcher who tampered with investigation up to 8 retractions

Karel Bezouška, the scientist who tried to derail an investigation into his work by breaking into a lab refrigerator has had an eighth paper retracted. Here’s the notice for “Synthetic N-Acetyl-d-glucosamine Based Fully Branched Tetrasaccharide, a Mimetic of the Endogenous Ligand for CD69, Activates CD69+ Killer Lymphocytes upon Dimerization via a Hydrophilic Flexible Linker:”

Seventh retraction appears for author who tampered with investigation

Karel Bezouška, who tried tampering with an investigation into his work by breaking into a lab refrigerator, has had a seventh paper retracted. Here’s the notice for “Carboxylated calixarenes bind strongly to CD69 and protect CD69+ killer cells from suicidal cell death induced by tumor cell surface ligands,” which was first published in Bioorganic & … Continue reading Seventh retraction appears for author who tampered with investigation

Author who broke into lab to tamper with investigation now up to half a dozen retractions

Karel Bezouška, the scientist who tried to tamper with an investigation into his work by breaking into a lab refrigerator, has had his fifth and sixth papers retracted. Here’s the notice from Bioconjugate Chemistry for 2012’s “Dimerization of an Immunoactivating Peptide Derived from Mycobacterial hsp65 Using N-Hydroxysuccinimide Based Bifunctional Reagents Is Critical for Its Antitumor … Continue reading Author who broke into lab to tamper with investigation now up to half a dozen retractions

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

We’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 … Continue reading Retraction of 19-year-old Nature paper reveals hidden cameras, lab break-in, evidence tampering
