Revealing the pathogenesis of gastric intestinal metaplasia based on the mucosoid air-liquid interface

Journal of Translational Medicine
Background Gastric intestinal metaplasia (GIM) is an essential precancerous lesion. Although the reversal of GIM is challenging, it potentially brings a state-to-art strategy for gastric cancer therapeutics (GC).

Fore-aft clearance controls how three-dimensional confinement affects micropropulsion [PDF]

arXiv, 2022
Systems of active particles are often affected by confinement due to nearby boundaries. Recently, there has been interest in the effect of confinement by complex three dimensional geometries, as might occur in structured environments such as porous media, foams, gels, or biological tissues and ducts.
