Permselective silicon-containing vinyl copolymers
Polymer, 1994Abstract This paper presents the synthesis of copolymers of vinyl p-t-butylbenzoate (PTBBA) with 3-methacryloxypropyltris(trimethylsiloxy)silane (Si-1) and their permselective properties for oxygen and nitrogen. Analysis of the glass transition temperature profile by the Kwei equation implied the existence of some interaction between PTBBA and Si-1 ...

Mechanisms of Glomerular Permselectivity
1983The hydraulic pressure gradient acting across the glomerular capillary wall serves as the principal driving force for the separation of plasma into a nearly ideal ultrafiltrate. In spite of its remarkably low resistance to water flow, however, this capillary network retains within it the plasma proteins, so that only a small fraction of these ...

Selectivity enhancement using permselective microcapsule
Chemical Engineering Journal, 2012Abstract Multi-competitive enzymatic reactions were performed to determine the selectivity properties of enzymes immobilised in polyacrylamide-alginate 2 (pAAm-Alg) microcapsules. The transesterification of fatty acid ethyl esters of different chain lengths (C 2 –C 14 ) with various alcohols catalysed by the enzyme lipase Mucor Miehei was chosen

Renal hemodynamics and permselectivity.
Journal of the American Society of Nephrology : JASN, 2006Glomerular capillary hemodynamics influence glomerular permselectivity to macromolecules, and alterations in these factors can evoke proteinuria. Changes in hemodynamic patterns can alter protein flux by changing its diffusion- or concentration-driven movement in the presence of a constant membrane barrier. Alternatively, hemodynamic forces may disrupt,

An amphoteric Ion-permselective membrane
Desalination, 1975Abstract A membrane made by reacting sulphochlorinated polyethylene with 1-amino-3-dimethylamino-propane containing water, was found to be amphoteric: about 5 6 of its capacity was due to dimethylamino groups while sulphonic acid groups accounted for the remaining 1 6 of its capacity. In acid the dimethylamino groups are ionised and the

Structural determinants of glomerular permselectivity.
Federation proceedings, 1977Molecular size has been considered in the past to be the major factor in glomerular restriction of macromolecules. Ultrastructural tracer studies have suggested that the restrictive barriers(s) are present in the glomerular basement membrane (GBM), the epithelial filtration slits, or both. Recent morphologic and functional tracer studies have indicated
