Methodology was developed for presenting to fish cells in culture whole-water samples without extraction and used to evaluate the toxicity to a rainbow trout gill cell line, RTgill-W1, of more than 30 whole-water samples collected from a paper mill over ap ...
Methods are provided for producing microcapsules based on two oppositely charged polymers, in particular to optimise the permeability and mechanical stability of microcapsules. The capsules are formed by introducing liquid droplets from an aqueous solution ...
Conformational changes occurring upon membrane binding and subsequent insertion of staphylococcal alpha-toxin were studied using complementary spectroscopic techniques. Experimental conditions were established where binding could be uncoupled from membrane ...
A review with 9 refs. Description of polyelectrolyte complex formation by anal. ultracentrifugation, exptl. detection of membrane formation, and study of membrane formation are introduced. [on SciFinder (R)] ...
This paper introduces the notion of Voronoi diagrams and Delaunay triangulations generated by the vertices of a piecewise flat, triangulated surface. Based on properties of such structures, a generalized flip algorithm to construct the Delaunay triangulati ...
Tumor necrosis factor TNF can trigger increases in membrane conductance of mammalian cells in a receptor-independent manner via its lectin-like domain. A lectin-deficient TNF mutant, lacking this activity, was able to bind to artificial liposomes in a pH-d ...
A review with 91 refs. The use of solid-state NMR as a tool to det. the structure of membrane mols. is reviewed with a particular emphasis on techniques that provide information on orientation or order. Expts. reported here have been performed in membranes ...
Batch cultures of a mouse/mouse hybridoma cell line secreting a dimeric IgA were performed in combination with a membrane process for the continuous removal of ammonia from the culture medium. The latter involves hydrophobic porous membranes with an assocd ...
The synthesis, characterization, and membrane-transport properties of a series of benzo-15-crown-5- andp-tert-butylcalix[4]arene-substituted polysiloxanes are described. Receptor-functionalized poly(dimethylsiloxane)s, randomly substituted with up to 37 mo ...
New types of oxygen-sensitive membranes based on immobilized (meso-α,α,α,α-tetrakis(o-pivalamidophenyl)porphinato)cobalt(II) (CoP) were prepared, and their optical response behavior was studied. The complex CoP was immobilized on poly(octylmethacrylate-co- ...
