Transepithelial Transport and Metabolism of Thyrotropin-Releasing Hormone (TRH) in Monolayers of a Human Intestinal Cell Line (Caco-2): Evidence for an Active Transport Component?

AbstractCell culture models for gastrointestinal transport and metabolism are important mechanistic tools. Our studies of Caco-2 monolayers demonstrate heterogeneity in transport characteristics depending on passage number and origin of the cells.

Diffusion in zeolites: is surface resistance a critical parameter?

Gravimetric uptake measurements were performed with cyclohexane for different Silicalite-1 crystals sizes. It was observed that the apparent diffusion coefficients vary with crystal size, confirming the existence of a surface resistance.

A dynamic model for assessing the impact of diffusing capacity on arterial oxygenation during apnea

Preterm infants have a reduced pulmonary diffusing capacity that has been invoked to explain rapid arterial O2-desaturation during apnea, despite little evidence to support this view.

Approximations to and local properties of diffusions with discontinuous controls

AbstractThe paper discusses several properties of control systems defined by stochastic differential equations, which are defined by the method of Girsanov, using a transformation of measures, and where the controls are discontinuous.

Optimal diffusion of a new technology when both demand and supply are nonstatic

AbstractThe investment problem of a monopolized sector selling an innovated product is explored. Learning by doing is supposed to occur on the supply side, while learning by using is introduced to explain demand growth.
