Citations lend credibility to a scientific paper. And sometimes even result in a cash bonus. But while most researchers just hope their paper will be cited by others, some authors have found more ‘creative’ ways of getting their papers noticed. A recent comment on PubPeer offers a glimpse behind the scenes.Continue reading “Citation Statistics and Citation Rings”
Most of these papers included reused images, presented as new experiments without proper citation, while some others appeared to show overlapping photos or duplicated elements within the same photo. You can read my 2020 blog post here.
I shared my concerns about these papers with the university in February 2019.
Today -March 23, 2022 – the University of Louisville sent their final decision to me, and I am sharing this here with their permission.
“The University of Louisville found there was no research misconduct. The institution followed its established, thorough, and robust process and made no findings of research misconduct against Dr. Ratajczak associated with any of the allegations, including all the allegations that continue to persist publicly on the internet. ”
In October 2020 and 2021 I reported a total of 21 papers published by Professor Vojtěch Adam that contained image problems. Vojtěch Adam is a professor in chemistry, and head of the Department of Chemistry and Biochemistry, at Mendel University in Brno, Czech Republic. He is a top Czech researcher in cancer and nanotechnology.
Today, a day before his appointment as the new Rector (Dean) of Mendel University, a committee released a report of their findings from an investigation into twelve of these papers. Their conclusions came as a big surprise.Continue reading “New Mendel University Rector found guilty of misconduct”
This is Part 3 of a series describing papers from the Institut Hospitalo-Universitaire Méditerranée-Infection (IHUMI or IHU) and Aix-Marseille Université (AMU) — institutions in Marseille, France — with potential problems.
In Part 1, I listed papers with image concerns. In Part 2, I focused on a set of papers describing many different research projects on specimens collected from homeless people — but all run under the same IRB approval number.
In this post, we’ll take a look at IHU/AMU papers describing samples obtained from people in African countries. Many of them lack wording on ethical approval by the local authorities, and all lack authors from these countries. This type of research might fall under the definition of neo-colonial science.Continue reading “Concerns about Marseille’s IHUMI/AMU papers – Part 3”
This is part 2 of a series describing papers from the IHUMI/AMU institutions in Marseille, France, with potential problems. In Part 1, I listed papers with image concerns. In this follow-up I’ll focus on a set of papers that might have problems with human subjects research not having received proper ethical approval. The articles span a decade of research on homeless people in Marseille, and involve different studies and specimens — but all were run under just one IRB approval number.Continue reading “Concerns about Marseille’s IHUMI/AMU papers – Part 2”
A group of anonymous persons filed a Statement of Concern with the FDA regarding the integrity of research papers about Simufilam, an Alzheimer’s Disease treatment drug candidate developed by Cassava Sciences (Nasdaq: $SAVA). The petition raises concerns about Western blots and methodology. I took a look at the problematic photos included in the report, and agree with most of those concerns. I also found some additional problems.Continue reading “Cassava Sciences: Of stocks and blots”
Last March, I shared my concerns about a paper from the IHU-Méditerranée Infection (IHUMI)/ Aix-Marseille University (AMU) claiming that Hydroxychloroquine in combination with Azithromycin could reduce coronavirus viral loads faster than no treatment.
Other papers by this group of researchers led by Professor Didier Raoult and/or his right-hand man Professor Eric Chabrière, also appear to contain problems, ranging from potentially duplicated images to ethical concerns.
In this blog post I have gathered the papers by the Raoult and Chabrière group that have image concerns. This post is not an accusation of misconduct, but a compilation of the potential problems found in 22 different papers by this group. I welcome the authors removing any concerns by providing the original figures.Continue reading “Concerns about Marseille’s IHUMI/AMU papers – Part 1”
A chemistry professor at Northeastern University in Boston, MA who has almost 70 papers flagged on PubPeer resigned yesterday, May 4, 2021.
On his blog For Better Science (Update May 5, at the bottom), Leonid Schneider shared an email from the Chair of the Department of Engineering, which states that Thomas J Webster has resigned from the university.
Webster has 69 papers flagged on PubPeer, mostly for concerns about image irregularities. I reported 59 to the journals and institution in March 2020.Continue reading “Northeastern University professor with 69 papers on PubPeer has resigned”
The Technion-Israel Institute of Technology is the oldest university in Israel, ranking itself ‘among the world’s top science and technology research universities’.
It is here that a group of researchers appears to have been publishing remarkably similar photos for the last decade — or more.Continue reading “Similar images from the Technion”
This week I worked on a large set of papers from a research group at the Tianjin Life Science Research Center at Tianjin Medical University. The group, headed by Dr. Hua Tang and funded by many National Natural Science Foundation of China grants, has published a total of 113 PubMed-indexed papers.
However, a significant number of these — 45 as of today — have PubPeer posts in which concerns are raised about their figures.Continue reading “Forty five papers from Tianjin Medical University”
