 D'Eyealogues - Fixing Epithelial Basement Membrane Dystrophy
Corneal epithelial adhesion was assessed immediately preoperatively using a cellulose surgical sponge (adhesion test), and the incidence, extent, and location of epithelial defects occurring during the microkeratome incision of the corneal flap were recorded.
The adhesion test was positive in 16 (80%) of corneas having macrodefects, with 4 (20%) false negatives.
Thus, the overall positive predictive value of the adhesion test [using a cellulose surgical sponge] was 59%

 CHEST: Is asthma an epithelial disease? - The Thomas L. Petty 37th Aspen Lung Conference: Asthma - Structure and ...
As the role of the airway epithelial cell in asthma is defined, it seems likely that new opportunities for therapeutic intervention will be possible.
Prostaglandin E, for example, is a product of airway epithelial cells[4] and has been suggested to mediate smooth muscle relaxation induced by airway epithelium.[5-7] Nitric oxide has been suggested as an additional epithelial-derived smooth muscle relaxing factor.
Sousa and colleagues,[26] for example, have used immunohistochemical techniques to demonstrate increased granulocyte monocyte colony stimulating factor (GMCSF) production by the asthmatic airway epithelium.

 The Varied and Surprising Spectrum of Mutations in Epithelial Cells - DERT
Background: Epithelial cells, such as skin cells, cells that line the intestinal and respiratory tracts, etc., comprise about 60% of the cells in the human body and are the source of about 85% of human cancers.

 REGULATION OF EBV INFECTION IN EPITHELIAL CELLS
Abstract: Epstein-Barr virus (EBV) infection in humans is associated with the development of both lymphoid and epithelial cell malignancies.
In this grant, we propose to continue our long-term studies investigating the mechanisms by which EBV latency is maintained or disrupted, with particular emphasis upon understanding the biology of EBV infection in epithelial cells.
The proposed studies should help define why EBV infection is normally lytic in epithelial cells (but not B cells), and will explore the mechanisms by which EBV infection becomes latent during the development of NPC.
