Authors fix three Diabetes papers flagged for image issues

without comments

diabetesResearchers have corrected three studies published in the journal Diabetes after users flagged issues with the images on PubPeer.

All three papers share a number of authors, including the same last and corresponding author, Aimin Xu, from The University of Hong Kong.

Since the corrections appear relatively extensive, we asked the journal if retractions were ever on the table. According to Chris Kohler, associate publisher, scholarly journals at American Diabetes Association, which publishes Diabetes, an ethical panel reviewed the papers before allowing the authors to issue the errata, all of which were published online this month: Read the rest of this entry »

JACS corrects, removes author from previously flagged paper

with 3 comments

JACSA paper at the center of a high-profile case of alleged misconduct in Hong Kong has earned a correction notice.

The correction replaces an expression of concern on the Journal of the American Chemical Society (JACS) paper, which followed allegations of data manipulation. It provides some un-cropped images, and removes a co-author from the paper. However, it does not appear to address previous allegations of misconduct, nor a recent ruling from an investigation at Hong Kong University (HKU), which found that some of the data were “invalid.”

Here is the correction notice for “Molecular Imaging of Peroxynitrite with HKGreen-4 in Live Cells and Tissues:”

JACS imaging paper “under editorial review” has been replicated, says author

with 11 comments

JACS The author of a paper “under editorial review” at the Journal of the American Chemical Society has told us the results the paper have been replicated, contrary to claims made by a former member of her lab.

What’s more, the author said she has submitted a correction to the paper, which is currently flagged with an expression of concern, to provide uncropped images.

We originally reported on the case in February from the perspective of Roger Wong, a former chemist at Hong Kong University who said he hasn’t been able to replicate the findings out of the lab of Dan Yang, a current chemistry professor at HKU (who is female, despite the fact that “Dan” is frequently used as a male name in English). We unfortunately failed to reach Yang in February because of an email glitch; once we contacted Yang, she told us she does not believe Wong’s side of the story:

The Journal of the American Chemical Society has issued an expression of concern over “the presentation of results” in a 2014 paper about a new probe for use in imaging.

We haven’t heard back from the journal nor the authors of the paper, so there’s not much we can officially say about what the journal is investigating.

Here’s the text from the expression of concern:

Image issues force retraction of liver transplant papers

with 7 comments

ajtranspA group of researchers in Hong Kong and China have lost a pair of papers on liver transplantation after concerns were raised about the “origin of images” in the two studies.

The articles appeared in the American Journal of Transplantation in January and February of 2006, and came from the lab of S. T. Fan, of the University of Hong Kong. When the authors were asked about the images, they “were unable to satisfactorily mitigate the concerns.”

According to this bio from the journal Hepatobiliary Surgery and Nutrition, Fan: Read the rest of this entry »

Investigation ups nursing researcher’s retraction count to 3

with 2 comments

Journal of Clinical NursingThe Journal of Clinical Nursing is retracting a paper “due to major overlap with a previously published article” from the same journal, following an investigation by the National University of Singapore.

By our count, this is the third retraction for first author, Moon-fai Chan, all for “overlap” with other papers.

As we reported in May, the Journal of Advanced Nursing retracted a paper co-authored by Chan for “major overlap” with a paper in JCN, that too the result of the investigation. We’ve also learned that the journal Nursing & Health Sciences issued a similar notice last year for another pair of overlapped papers.

Chan said in a statement to Retraction Watch Read the rest of this entry »

Marine mammal injury study retracted for using restricted gov’t data

with one comment

Integrative ZoologyA 2012 paper that analyzed injuries to aquatic mammals in China has been retracted “due to the usage of restricted data from the Ministry of Agriculture of China.”

The authors — from Shandong University in China, The University of Hong Kong and the Peruvian Centre for Cetacean Research — “organized the collection of official documents related to strandings, bycatches and injuries of aquatic mammals in the waters of mainland China from provincial fishery administrations for the years 2000 to 2006,” according to the abstract. However, they may not have been supposed to do that.

Here’s the retraction notice from Integrative Zoology (which is paywalled, tsk, tsk):
