Digestive Diseases and Sciences has retracted two papers for duplication.
The first paper, “Membrane-Bound Mucins and Mucin Terminal Glycans Expression in Idiopathic or Helicobacter pylori, NSAID Associated Peptic Ulcers,” was published in October 2012 by a group from Israel and the United States. It found that:
Cytoplasmic MUC17 staining was significantly decreased in the cases with idiopathic ulcer. The opposite was demonstrated for MUC1. This observation might be important, since different mucins with altered sialylation patterns likely differ in their protection efficiency against acid and pepsin.
But, as the retraction notice suggests, that much had been found before: Continue reading A double-bill from Digestive Diseases and Sciences, both for regurgitation — aka duplication
