No animal testing before Walles tracheal transplants, admits Fraunhofer Society

No animal testing before Walles tracheal transplants, admits Fraunhofer Society

The tracheal transplant experiments on three human patients were performed by the German scientists Heike and Throsten Walles without any previous animal testing, as now admitted to me by the Fraunhofer Institute for Interfacial Engineering and Biotechnology (Fraunhofer IGB) in Stuttgart.  It also came to light that the pig intestine-based tracheal transplant was eventually deemed as too toxic, and a follow-up animal testing was apparently cancelled. Heike Walles is still associated with Fraunhofer IGB while being together with her husband employed as professors at the University Clinic of Würzburg. A patient of theirs received in 2007 a tracheal transplant of unknown size and shape, prepared from decellurised and in vitro re-populated pig intestine; this unnamed person died only some weeks after, of causes unknown to us. We know however, that two weeks before that operation, a tubular tracheal graft made from pig intestine was test-implanted into the patient’s arm for a week. After a quick analysis, a second in parallel prepared graft was implanted into the patient’s airways. Remarkably, only preliminary first in-arm test, but not the main operation, was ever published (Mertsching et al 2009), around two years after the patient’s death. The next patient, an Indian immigrant Pavninder Singh, received a large tracheal patch, which apparently did not perform as expected: the patient’s tracheostomy had to be re-opened, there was also apparently heavy inflammation. That patient committed suicide 2.5 years after the operation, and became in 2013 a central character of a book chapter which described his and the scientists Walles’ story (Bernhard Albrecht, “Patient of My Life”). Only in 2015 was the case of that patient published as a research paper (Steinke et al, 2015), his tracheostomy went for some reason unmentioned, just like the fact that Singh was no longer alive since 2011. All these tracheal transplants were prepared in the lab of Heike Walles (back then under her former husband’s name Mertsching) at Fraunhofer IGB, the transplantations took place at the neighbouring  Robert Bosch Hospital, Clinic Schillerhöhe,  where Thorsten Walles used to work as surgeon, before becoming professor in Würzburg. The details can be read in this article. Continue reading “No animal testing before Walles tracheal transplants, admits Fraunhofer Society”

Open Letter in support of my investigation of trachea transplants in Germany, by Rafael Cantera

Below a support letter by Rafael Cantera, professor of zoology at the University of Stockholm in Sweden, addressed to the leadership of the University Clinic Würzburg. This is because two professors of this German university, Thorsten Walles and Heike Mertsching (now Walles) chose to respond to my inquiries about their earlier trachea transplants made from pig intestine (see my detailed report here) with lawyers’ financial blackmail and right after, with court actions, which had me sentenced guilty with a  threat of a prison term of 6 months, without my prior knowledge (see case description here). Such are the peculiarities of German law: internet bloggers are basically  legally defined here by default as criminals, and professors as infallible and divine beings (in fact, even Walleses’ former boss and collaborator Paolo Macchiarini is still a protected adjunct professor at their former common place of work, the Medical University Hannover). I received lots of support from my readers, and was also invited to give an interview with the French magazine Mediapart (German version here). Now, I am deeply grateful to Prof. Cantera for his support, and hope other international and maybe even German academics join in and sign below.  Continue reading “Open Letter in support of my investigation of trachea transplants in Germany, by Rafael Cantera”

The western blot doctors of Silesia

The western blot doctors of Silesia

Protein expression analysis by western blots appears to be the weak spot of life science, because these blots are so often reported to be manipulated. However, this is only because anybody, even without any background in biology can spot re-used western blot bands, just using a good eye or some computer skills. Unlike with other analytical tools, like real-time PCR or microscopy imaging, you don’t need specialist knowledge or access to raw data to spot digital manipulations of western blots. One of the most famous western blot breeders is the Brazilian diabetes researcher Mario Saad (see whistleblower reports on my site here and here). Below is the case of his two colleagues from Poland.

Some time ago, I was contacted by a Polish scientist with a dossier of suspected western blot duplications in the publication of the pharmacologist Bożena Gabryel from the Department of Pharmacology at the Medical University of Silesia in Katowice, Poland. Gabryel specializes in oxidative stress research, four of her publications on this topic were accused to feature duplicated western blots, in different context. Sometimes suspicions were raised that selected individual bands in different western blots look too similar, which might suggest manipulative band duplications.

Soon after, another whistleblower independently contacted me with another dossier about yet another set of Gabryel’s papers, all featuring as lead or even corresponding author Krzysztof Łabuzek, who is an adjunct professor at this same Medical University  of Silesia with interest in immune system and who also has a clinical practice for internal medicine in a small town near Katowice. Labuzek’s papers seem to feature a whole gallery of re-used western blots, as the dossier suggests. Additionally, that second whistleblower expressed concerns about  western blot splicing and suspected band re-used in papers featuring the first author Joanna Ślusarczyk, PhD student in the lab of Agnieszka Basta-Kaim at the Polish Academy of Sciences in Krakow. Basta-Kaim is also co-author on one Gabryel paper now suspected of data manipulations.

Macchiarini and his Russian megagrant

Macchiarini and his Russian megagrant

Below I am publishing the most recent dossier authored by the four whistle-blowers from the Karolinska Institutet (KI) in Sweden: Oscar SimonsonKarl-Henrik Grinnemo, Matthias Corbascio and Thomas Fux. Two of their earlier notifications of research misconduct to KI by their former colleague Paolo Macchiarini are available in full on my site, here and here.

This time it is about Macchiarini’s trachea transplants in Russia, and the so-called Megagrant funding he received from the Russian government for his work at the Kuban State Medical University in Krasnodar. The accusation goes that the KI star surgeon misrepresented the true outcomes of his two first disastrous human experiments with a plastic trachea, performed at KI on the patients Andemariam Beyene and Chris Lyles, both of who died. Also, the whistle-blowers criticise that KI failed to investigate these failed transplants and patient deaths and did not report those to the Russian authorities, which might have helped avoid the unnecessary deaths of at least two Russian patients, Yulia Tuulik and Alexander Zozulya.

Bavarian court sentences me to prison if I dare repeat unwelcome facts of Walles’ trachea transplants

Just before the end of the year 2016, I received per mail an official letter from the Bavarian Regional Court in Würzburg, where I was found guilty of lies and libel in a trial I was not invited to. Under the threat of a prison sentence of 6 months (since I could never pay even a fraction of the fine of €250,000) I was ordered by the judge to remove a short paragraph from this article which described the same tracheal transplants which the Würzburg University professors Heike and Thorsten Walles were proudly promoting through all available media only a couple of years ago. Now, when the trachea transplant scandal around their former collaborator Paolo Macchiarini exploded, the mere reference to their earlier common publications amounts to a crime of libel in the German state of Bavaria. I was also sentenced to pay the court costs, though I only learned about this Kafkaesque “Prozeß” once a final decision against me was delivered by mail. Luckily, I still have the right to appeal, which I will do once I recruit a suitable legal counsel. If you wish to help in any way, please get in touch.
