Fried Divine Comedy, featuring anti-cancer cockroach and phallic fungus

Fried Divine Comedy, featuring anti-cancer cockroach and phallic fungus

This is a follow-up to the previous article, about a misconduct investigation at the Cardiff University in UK into the published works of cancer researcher Wen Jiang, professor of Surgery and Tumour Biology, Fellow of Royal Society of Medicine and chair of Cardiff China Medical Research Collaborative. The following guest post by my regular contributor Smut Clyde now delves deep into the peculiar approach with which Professor Jiang intends to cure cancer: namely by peddling herbal (and not so herbal) medicinal powders, manufactured by a Chinese company Yiling Pharmaceuticals. Jiang sees there no conflict of interest, even in presenting the patented concoctions of Yiling as his own research in Cardiff. It is not exactly the case that Jiang was hiding his connections to Yiling, outside of his conflict of interest declarations, that is. His own Cardiff University initiated the collaboration with the Chinese company in 2013 and proudly announced the engagement to the British Parliament in 2014. In 2015, Yiling helped Jiang and Cardiff University to organise The China–United Kingdom International Cancer Conference, attended by the First Minister of Wales and the Vice-Chancellor of the Cardiff University.

Jiang’s cancer-fighting magic ingredients are ginseng and other herbs, plus a cockroach, a parasitic fungus and bits of chicken gizzard, all sold by Yiling. Sometimes it includes Divine Comedy (don’t ask). Yiling’s potion named “Yangzheng Xiaoji” was certified by Cardiff University in an Impact statement as a metastasis inhibitor, which “has been shown to be beneficial to patients with certain solid tumours when used alone…“. The sole basis for this bold claim from respected British university was a 2009 paper by Yiling in an obscure Chinese journal, which incidentally is edited and published by Yiling.

Oncogene EiC Justin Stebbing, a hypocrite of research integrity?

Oncogene EiC Justin Stebbing, a hypocrite of research integrity?

The cancer research journal Oncogene issued on October 16th 2017 an Editorial on the topic of research integrity:

“The importance of being earnest in post-publication review: scientific fraud and the scourges of anonymity and excuses”.

The editorial contains a list of 8 common excuses dishonest authors used to escape responsibility for manipulated data. It was authored by David Sanders, virologist and professor at the Department of Biological Sciences at the Purdue University in West Lafayette, Indiana, US, as well as Justin Stebbing, professor of cancer medicine and oncology at the Imperial College London, UK, who is also one of the two Editors-in-Chief (EiC) of the journal Oncogene. Sander is one of these rare brave academics who is unafraid to call out scientific misconduct while his peers hide in the bushes and instead even point fingers at whistleblowers like him. As the newspaper USA Today wrote earlier this year, Sanders made himself a very powerful enemy, the star US cancer researcher with Italian origins, Carlo Croce:

“But that didn’t stop Sanders from alleging that Dr. Carlo Croce, a prominent cancer researcher at Ohio State University, falsified data or plagiarized text in more than two dozen articles Croce has authored. For the past two-plus years, Sanders has contacted scientific journals in which the articles appeared to alert them of his concerns. Earlier this month, he went more public with his claims in an investigative piece by the New York Times that delved into years of ethics charges against Croce.

“There are, and I anticipate there will be additional, consequences for my career,” Sanders said Tuesday afternoon while sitting in his office inside the Hockmeyer Hall of Structural Biology at Purdue.

This isn’t the first time Sanders has publicly accused a scientist of bad behavior. In 2012, Sanders had an article by a former colleague retracted on the basis that the colleague used their former deceased research partner’s data in the paper without permission”.

A long article appeared in The New York Times prior to that, “Years of Ethics Charges, but Star Cancer Researcher Gets a Pass“, detailing the case of Carlo Croce and the role of Sanders the whistleblower, and the Ohio State University, who were mostly covering up the affair. Croce hit back: he is now suing the newspaper, and in separate lawsuit, also Sanders at a New York court, as reported by Retraction Watch.

Hence, Sanders knows first-hand what research misconduct is and how to act upon it. Indeed, the editorial was his idea, and his co-author Stebbing joined afterwards. As Sanders wrote to me:

“The impulse for the editorial and the list was from me.  We discussed the inclusion of particular items and how they were described together”.

Stebbing indeed is not much of a whistleblower, quite the opposite, he can be in fact seen as victim of such. His own publication was heavily criticised on PubPeer, for suspected western blot band duplications. And the piquant bit is: Stebbings, together with his first author  Georgios Giamas (now Reader in Biochemistry at the University of Sussex, UK) offered on PubPeer explanations which sound very much as what he himself has been ridiculing in the Sanders & Stebbing editorial in his journal Oncogene.

Chocolate health: advice by Thomas Lüscher and peer review by Jonas Malmstedt

Chocolate health: advice by Thomas Lüscher and peer review by Jonas Malmstedt

Christmas season is the time to eat lots of chocolate. And as science teaches us, your confectionery is actually the superfood which will make you healthy, slim and clever. Good for you, good for the chocolate industry which often generously sponsors such scientists.

In May 2016, I brought a story about chocolate health research and how it is funded by food industry giants Mars and Nestle. The main protagonist was Thomas Lüscher, cardiology professor at the University of Zürich and head of the heart centre at the University Hospital Zurich in Switzerland. Lüscher postulated that eating dark chocolate daily is beneficial for heart insufficiency patients and may prevent heart attacks, he now offers some additional advice. Now his peer, the Swedish vascular surgeon Jonas Malmstedt, provides his analysis of Lüscher’s publications below. Another study which Malmstedt unpicks, is an opus from the Luxembourg Institute of Health (Alkerwi et al, 2016), which declared that eating chocolate makes you younger and healthier, and prevents diabetes on top.

The Voinnet investigator and the tricky issue of conflict of interests

The Voinnet investigator and the tricky issue of conflict of interests

Great scientists never have any conflicts of interests, and in the case of the investigation of the research misconduct by the plant scientist Olivier Voinnet, led by his Swiss employer ETH Zürich, this was also apparently the case. Voinnet was found guilty of misconduct and admitted image manipulations in many papers. Yet his science remained largely unquestioned, and even original data behind the most outrageously manipulated figures was said to have been available in many cases. The ETH investigation recommended 6 retractions, one of which was even avoided thanks to the concerns the journal Science had towards that paper’s junior authors (Voinnet’s current retraction count stands at 8 papers and almost 20 corrections, where manipulated data was simply exchanged with new one). Professor emeritus Witold Filipowicz, of the Friedrich-Mieschner-Institute in Basel, is like Voinnet a specialist in the field of regulatory small RNAs, and he was therefore one of two external Voinnet investigators whom ETH invited in early 2015. It did not matter to ETH that it was actually Filipowicz who nominated Voinnet for the EMBO Gold Medal, which the disgraced plant scientist then lost after EMBO’s own investigation into his many years of data manipulation.

Regenerating in Hannover, Part 2: Axel Haverich’s “growing” heart valves

Regenerating in Hannover, Part 2: Axel Haverich’s “growing” heart valves

The science of the fallen star of regenerative medicine Paulo Macchiarini was simple: take a dead organ, strip it of its cells and seed the carcass with stem cells (usually the magic cells from bone marrow). After some days in a “bioreactor”, you take out a living trachea, esophagus, even heart, and implant it into a patient. Another human life saved, and not only media, even scientist colleagues fell for this outrageous quackery. As the result of this hubris, several patients died, others remained in permanent critical care. Macchiarini and his partners Philipp Jungebluth, Martin Birchall and others had to fake ethics approvals as well as to lie and cheat about medical records in their publications in The Lancet, all in order to present a miserably suffering recipient of a ”regenerated” trachea as fully recovered. Animal experiments were performed only after Macchiarini’s team operated their first human patient, as indirectly evidenced by Jungebluth’s own doctorate thesis at the Medical University Hannover (MHH) in Germany.

Macchiarini began to develop his “decell-recell” method of organ regeneration while working in Hannover, close to the renowned heart surgeon and MHH clinic director, Axel Haverich (see Part 1 for the background). In 2009, the Italian cheater then moved on to a professorship at the Karolinska Institute in Stockholm, where he was showered in funding money and received best institutional protection, despite his patient abuse and his lies about his qualifications.

The 3rd editor and failure of ‘proper channels’

The 3rd editor and failure of ‘proper channels’

A scientist finds serious measurement errors in three publications of his former collaborators. He alerts the journals and makes his concerns public, openly under his own name. The errors would make obsolete several key observations of an established German neurophysiology lab. Indeed, one journal retracts the criticised paper, another issues a correction describing the affected results as “not reliable”. The Editor-in-Chief of the third journal however accuses the whistle-blower of unspecified conflict of interests and retracts his already published letter to editor, in the process tainting his reputation with a public insinuation of research misconduct.

Here is this story in detail. Continue reading “The 3rd editor and failure of ‘proper channels’”

Chocolate is good for your funding

Chocolate is good for your funding

Chocolate is good for your health, scientists keep saying. This may sound counter-intuitive; given that chocolate is an extremely calorie-rich confectionery, which mostly contains industrially refined cocoa fat and huge quantities of added sugar, a substance finally about to be recognised as the prime cause for the obesity epidemics.

A recent clinical study from the Luxembourg Institute of Health, published in the British Journal of Nutrition (Alkerwi et al, 2016), discovered that “chocolate consumers (81·8 %) were more likely to be younger, physically active, affluent people with higher education levels and fewer chronic co-morbidities”. The authors used data from the nationwide Observation of Cardiovascular Risk Factors in Luxembourg (ORISCAV-LUX) survey to determine that “chocolate consumption may improve liver enzymes and protect against insulin resistance, a well-established risk factor for cardiometabolic disorders”. Basically, this paper advices hyperglycaemic and diabetic patients to eat sugar-rich confectionery, which may appear somewhat irresponsible or even dangerous. These alleged chocolate benefits on diabetes prevention present a new turn in a long history of bold claims about the medicinal magic inside the sweets wrapper. Moreover, the lead author Ala’a Alkerwi also determined that chocolate improves cognitive capacities (Crichton et al 2016).

A fresh editorial in the BMJ journal Heart simply asked: “Is life longer with a box of chocolates?”. The authors Donaldson et al present “the health benefits of eating chocolate” as a scientific fact, which only needs physiological and molecular elucidation. Clinical studies have allegedly proven that regular consumption of chocolate reduces risk of heart attack and heart failure. The authors, led by Phyo Kyaw Myint, Chair for Medicine of Old Age at University of Aberdeen, decree that “future studies will need to narrow down exactly how chocolate exerts its beneficial effects”.

There were however quite a lot of chocolate studies done for more than a decade, funded with millions from the public, but also from the chocolate industry. Reliable reports of people cured of any cardiovascular diseases by eating chocolate do not exist. Even the health benefits of the purportedly medicinal raw cocoa ingredients of the flavanol compound family are far from being conclusively proven.
