Human squamous epithelial cells produce lower amounts of laminin and fibronectin when cultured on DEAE-dextran than when cultured on gelatin-coated polystyrene (Biotechnol. Bioeng., 33:1235). The epithelial cells also spread much more slowly on DEAE-dextran than they do on gelatin-coated polystyrene. To determine if the low level of matrix production by cells grown on DEAE-dextran contributed t...

HYPOTHESIS Various forms of electrical stimulation can improve wound healing in different tissues, but their application to gastrointestinal tract healing has not been investigated. We assumed that positively charged diethylaminoethyl cross-linked dextran bead (diethylaminoethyl Sephadex [DEAE-S]) particles would have a beneficial effect on the healing of colonic anastomoses. DESIGN Experimen...

Euler’s equation expresses the relationship between the velocity and the pressure fields in inviscid flow. Written in terms of streamline coordinates, this equation gives information about not only about the pressure-velocity relationship along a streamline (Bernoulli’s equation), but also about how these quantities are related as one moves in the direction transverse to the streamlines. The tr...

Streamline methods have received renewed interest over the past decade as an attractive alternative to traditional finite-difference (FD) simulation. They have been applied successfully to a wide range of problems including production optimization, history matching, and upscaling. Streamline methods are also being extended to provide an efficient and accurate tool for compositional reservoir si...

Basic polysaccharide strongly inhibited the hydrolysis of trioleoylglycerol (TO) emulsified with phosphatidylcholine and taurocholate by either pancreatic lipase or carboxylester lipase. DEAE-Sephadex dose-dependently inhibited the hydrolysis of TO by pancreatic lipase and carboxylester lipase; however, carboxymethyl-Sephadex and Sephadex G-50 did not inhibit the hydrolysis. Polydextrose (PD), ...
