Seventy-three papers published between 2004 and 2017 by scientists at the Indian Institute of Toxicology Research (CSIR-IITR), Lucknow have serious problems with the images. Leading the pack with 40 problematic papers is Dr. Yogeshwer Shukla, a senior scientist at IITR. He says investigation is already under way at the institute.

Publishing papers by plagiarising is on the wane in India with almost all journals checking for plagiarism at some stage before papers get published. So, Indian researchers seem to have gained expertise at another kind of fraud — manipulating images, producing images by repeatedly using certain portions in one frame and reuse of images in the same paper or from those published earlier. Or probably, Indian researchers manipulated images the same way they used plagiarised content. Only that  papers with manipulated images are now being exposed as more researchers based outside India have started looking for them.

At last count, 73 papers published between 2004 and 2017 by scientists at the Indian Institute of Toxicology Research (CSIR-IITR), Lucknow have serious problems with the images. The final numbers might be way higher if one were to critically look at all papers published by scientists at IITR during the last 20-25 years. 

All the 73 papers listed below have been posted on Pubpeer website by independent researchers who have an eye to spot image manipulation and duplication, something that peer-reviews seem to have failed to spot at the time of reviewing the manuscripts.

Leading the pack with 40 problematic papers is Dr. Yogeshwer Shukla, a senior scientist at IITR. In a blog post in For Better Science, Smut Clyde has exposed Dr. Shukla’s unethical practices in about 25 papers.

In an email, Dr. Shukla says: “It may please be noted that for reasons other than originality the papers are now appearing in Pubpeer. I have also been informed that this information of Pubpeer is addressed by a committee at our institute to verify  authenticity.”

While not denying the problems cited on Pubpeer, over telephone he says: “We are hurt. I admit that unintentional mistakes might have been made. There was no way to check if the images have already been used in other papers. This is done just to create doubts about Ayurveda and to target someone. A committee is looking into it and we will clarify each and every query raised by the committee.”

A pattern with problematic papers

There is a pattern to the kind of manipulation that IITR researchers seem to have resorted to. Manipulated and reused Western Blots are the most common.  They are also a little harder to spot. The most common practice is to duplicate bands of Western Blot for completely different experiments mostly in the same paper and at times in other papers.

“Western blots are the most common types I see in papers with photographic images and those are also the ones I seem to find the most,” Dr. Elisabeth M. Bik, Science consultant at Harbers-Bik LLC, San Francisco, California says in an email. Dr. Bik has an eye for manipulated images and has caught tens of papers.

Duplication of microscopic images within the same paper and between papers is the next common practice adopted by IITR scientists. While using the same image within the same panel or between panels in the same paper might arise from honest mistakes at the time of making the panels, repeating them in papers dealing with very different experiments can be called outright fraud.

“[In general], simple duplications (same magnification, same orientation) are the most common, and they might just be simple errors, caused by selecting the same image twice instead of picking the correct one. After that, overlapping images are very common as well. Rotated or manipulated images (in which the same cells are visible multiple times) are less common, but also harder to spot,” says Dr. Bik.

“There is no good software yet on the market to automatically screen images for duplications, but several journals and publishers use human eyes for initial screening, and subsequently software to help confirm irregularities in background noise or similarities using false-colour imaging,” she adds.

Retracted papers

Two of his papers published in 2011 in PLOS ONE and another in Life Sciences in 2007 were retracted for problematic images. Both the papers were listed on Pubpeer website (here and here) and the problems listed with the images have been cited by the journals in their retraction notice. The third one that has been retracted is an old paper.

After pointing out the problematic images in the retraction notice, PLOS ONE says: “The authors have been unable to provide any primary data underlying the figures. The authors commented that the regions of similarity in histopathological images arose due to similarity in lesions studied. For the similarities noted in flow cytometry plots, the authors commented that this could have arisen due to similarity in equipment and protocols. In the absence of the data underlying the figures and in light of the above concerns, the PLOS ONE Editors retract the article.”

The retraction note in Life Sciences paper notes: “Multiple figures in this article appear to be falsified/fabricated.

“Figure 2A. The images appear to be rotated and reused.

“Figure 3A. The Beta-actin band appears to be identical to articles from multiple [four] other journals.

“Figure 6. The Beta-actin band appears to have been reused and possibly manipulated.”
