“Additionally, the authors were unable to identify” co-author: Another retraction for Lemus

env microWe’ve been following the case of Jesús A. Lemus, the Spanish veterinary researcher with five retractions and two expressions of concern under his belt so far for suspected data fabrication and including a fake author on his papers.

Yes, a fake author. When this story first broke, El Pais called Javier Grande a ” ghost with a good academic background with at least six scientific publications in international journals.”

Grande’s — and Lemus’s — publication count declined by one more yesterday, as Environmental Microbiology retracted a 2007 paper: Continue reading “Additionally, the authors were unable to identify” co-author: Another retraction for Lemus

Not immune: Jesús A. Lemus earns another Expression of Concern

Jesús A. Lemus, the Spanish researcher whose work has left a lot of people questioning his data, has another Expression of Concern for his resume.

Here’s the notice, from Functional Ecology: Continue reading Not immune: Jesús A. Lemus earns another Expression of Concern

Lemus, Stapel each rack up another retraction

The retraction counts keep mounting for two Retraction Watch frequent flyers.

First, Diederik Stapel’s 26th retraction, according to our count. Psychologist Stapel admitted to making up data in dozens of studies, and is also facing a criminal inquiry for misuse of funds.

Feeling sheepish: Another retraction for Lemus, of study of whether livestock can spread chlamydia to birds

Jesús A. Lemus, the Spanish veterinary researcher whose work has been the subject of a misconduct inquiry, has another retraction for his CV. It’s his third, according to our count.

The newest retraction is from PLoS ONE:

Walk (back) an Egyptian (vulture): Another paper by Spanish vet under scrutiny retracted

With apologies to the Bangles for this post’s title, we have another vulture-related retraction from Jesús A. Lemus, the Spanish veterinary researcher whose results have come into question.

This one involves a paper that appeared in PLoS ONE in 2009, titled “Susceptibility to Infection and Immune Response in Insular and Continental Populations of Egyptian Vulture: Implications for Conservation.”

Carrion, my wayward son: Vulture paper from Spanish researcher suspected of misconduct retracted

Back in March, we wrote about the doubts that had emerged in Spain about the work of a prominent local veterinary scientist, Jesús Ángel Lemus, suspected of being a data fabricator and inventor of co-authors (one in particular).

We hadn’t heard anything since about Lemus — who specialized in the effects of environmental toxins on birds — until now.

The Proceedings of the Royal Society B has retracted a 2009 paper by Lemus and a (legitimate) c0-author, Guillermo Blanco, of the National Museum of Natural History, and issued an expression of concern about another article on which both men appeared.

The retracted paper, “Cellular and humoral immunodepression in vultures feeding upon medicated livestock carrion,” has been cited seven times, according to Thomson Scientific’s Web of Knowledge, and purported to find that: Continue reading Carrion, my wayward son: Vulture paper from Spanish researcher suspected of misconduct retracted

Two more retractions for Spanish leukemia researcher Román-Gómez

The journal Haematologica has retracted two papers by José Román-Gómez, both of which involve image manipulation, bringing his total to four.

Here’s the first notice, for a 2007 article titled “Epigenetic regulation of human cancer/testis antigen gene, HAGE, in chronic myeloid leukemia” that has been cited 20 times, according to Thomson Scientific’s Web of Knowledge: Continue reading Two more retractions for Spanish leukemia researcher Román-Gómez

A Wnt-er’s tale: Blood pulls second signaling paper from Spanish scientists over image fakery

Blood has pulled a paper 2007 paper from a group of Spanish researchers, one of whom appears to have been manipulating images.

The group’s work became the focus of expressions of concern from the Journal of Clinical Oncology this spring and in 2010.

The article, “Epigenetic regulation of Wnt-signaling pathway in acute lymphoblastic leukemia,” purported to show “a role of abnormal Wnt signaling in ALL and establish a group of patients with a significantly worse prognosis (methylated group)” and earned a commentary on the significance of the findings.

But as the notice explains, the first author lifted and manipulated a figure from a previously published article: Continue reading A Wnt-er’s tale: Blood pulls second signaling paper from Spanish scientists over image fakery

JCO expresses concern over images from Spanish group that had aroused earlier concern

The Journal of Clinical Oncology has issued an expression of concern about a 2003 article by a group of researchers in Spain who appear to have had recurrent problems with images.

The paper has been cited 56 times, according to Thomson Scientific’s Web of Knowledge. Here’s the notice:

It has been brought to our attention, regarding Figure 1, Part A, that similarity exists between bands 3, 4, and 5 of the top row and bands 1, 2, and 3 of the bottom row, including the presence of artifacts, in the April 15, 2003 article by [Jose] RomanGomez et al, entitled, “Cadherin-13, a Mediator of Calcium Dependent Cell-Cell Adhesion, Is Silenced by Methylation in Chronic Myeloid Leukemia and Correlates With Pretreatment Risk Profile and Cytogenetic Response to Interferon Alfa” (J Clin Oncol 21:1472-1479, 2003).  This similarity has raised concerns about whether these rows represent independent data. We alerted the corresponding author, Dr. Roman-Gomez, of this concern, and he has repeated the experiment shown in the original Figure 1, with the results below. Although the results of the figure appear to be unchanged, we wish to inform the readers of this issue, so that they may make their own independent assessment.

Spanish veterinary researcher under suspicion of creating “ghost” author, fabricating data

The Spanish press has picked up on the story of a prominent veterinary scientist in that country who has been accused of research misconduct.

According to El Pais, the researcher, Jesús Ángel Lemus, whose areas of interest include the effects of toxins on birds, ran into trouble in December when colleagues complained to the Ethics Committee of the Higher Council for Scientific Research about the reproducibility of his results and other problems. That triggered an inquiry by the CSIC into Lemus’ body of work, an investigation that, evidently, could not find a body.
