Modulation by extracellular and intracellular iodide of volume-activated Cl- current in HeLa cells (1998)The patch-clamp technique was used to study the effect of extracellular and intracellular iodide on the properties of the volume-activated anion current in HeLa cells. Upon hypotonic challenge, HeLa cells responded by ...
-
(1998)Background: Helicobacter pylori produces a gastric mucosal inflammation characterized by neutrophil infiltration, due to the liberation of interleukin-8. Aim: To measure interleukin-8 levels in gastric mucosa samples from ...
