FLORES, AURA G. A., AND GEOFFREY Mr. G. SHARP. Endogenous prostaglandins and osmotic waterflow in the toad bladder. Am. J. Physiol. 223 (6) : 1392-1397. 1972.-Prostaglandins, at low concentrations, inhibit the osmotic water-flow response to antidiuretic hormone (ADH) and to theophylline in toad bladder. They have no effect upon the response to dibutyryl cyclic AMP. Thus the prustaglandins inhib...

This Letter reports the measurement of electro-osmotic flows (EOF) in microchannels with surface charge patterned on the 200 microm scale. We have investigated two classes of patterns: (1) Those in which the surface charge varies along a direction perpendicular to the electric field used to drive the EOF; this type of pattern generates multidirectional flow along the direction of the field. (2)...

The objective of the study was to develop Controlled porosity and elementary osmotic pump-based drug delivery systems of Glibenclamide. The elementary osmotic pump (EOP) consists of an osmotic core with the drug surrounded by a semipermeable membrane drilled with a delivery orifice through which drug releases where as in controlled porosity osmotic pump drug release is accomplished by the use o...

The authors have addressed theoretically the hydrodynamic effect on the translocation of DNA through nanopores. They consider the cases of nanopore surface charge being opposite to the charge of the translocating polymer. The authors show that, because of the high electric field across the nanopore in DNA translocation experiments, electro-osmotic flow is able to create an absorbing region comp...
