Observation of electro-kinetic phenomena by imposing oscillating pressure and voltage gradients across some epithelial membranes.
When hydrostatic pressure across epithelia fixed between a Ussing-type chamber was oscillated mechanically, the membrane potential was found to oscillate synchronously. When the transepithelial potential was oscillated artificially, the hydrostatic pressure difference also oscillated synchronously. Under such oscillating gradient conditions, concentration changes in the unstirred layer can be m...

15 صفحه اولUltrastructure and transport across epithelial membranes.
For epithelia, all too frequently this or that ultrastructure is spoken of as "absorptive" or '(secretory.'' Correlation between structure and function must relate to phenomena, such as the apparent active transport of weak electrolytes or water, that are unique for the epithelium. The macroscopic tubule of the gastric mucosa eannot sequester the active transport of hydrochloric acid from the s...

متن کاملOn Localized Vapor Pressure Gradients Governing Condensation and Frost Phenomena.
Interdroplet vapor pressure gradients are the driving mechanism for several phase-change phenomena such as condensation dry zones, interdroplet ice bridging, dry zones around ice, and frost halos. Despite the fundamental nature of the underlying pressure gradients, the majority of studies on these emerging phenomena have been primarily empirical. Using classical nucleation theory and Becker-Dör...
