Oxalate transport by anion exchange across rabbit ileal brush border.
This study demonstrates the presence of oxalate transporters on the brush border membrane of rabbit ileum. We found that an inside alkaline (pH = 8.5 inside, 6.5 outside) pH gradient stimulated [14C]oxalate uptake 10-fold at 1 min with a fourfold accumulation above equilibrated uptake at 5 min. 1 mM 4,4'-diisothiocyanostilbene-2,2'-disulfonate (disodium salt; DIDS) profoundly inhibited the pH-g...
متن کاملFacilitated Transport Membrane Systems
R. D. Noble, a research profissor in chemical engineering at the Univ. of Colorado, specializes in the use of reversible chemical reactions in chemical gas and liquid separation processes, most notably the use of ion-exchange membranes as supports for complexing agents and the modeling and analysis of various facilitated transport systems. Refore joining the Univ, of Colorado, he served as an a...
متن کاملThe relationship between anion exchange and net anion flow across the human red blood cell membrane
The conductive (net) anion permeability of human red blood cells was determined from net KCl or K2SO4 effluxes into low K+ media at high valinomycin concentrations, conditions under which the salt efflux is limited primarily by the net anion permeability. Disulfonic stilbenes, inhibitors of anion exchange, also inhibited KCl or K2SO4 efflux under these conditions, but were less effective at low...
متن کاملStudy the Transport Properties of Anion and Cation Exchange Membranes toward Various Ions Using Chronopotentiometry
The transport properties of various anion and cation exchange membranes were studied in different electrolyte solutions using chronopotentiometry technique to get insight about the influence of the counter ion on the transport properties of the membranes. The investigated samples include heterogeneous ion exchange membranes varying in the functionality of fixed charged gro...
متن کاملComputational modelling of amino acid exchange and facilitated transport in placental membrane vesicles
Placental amino acid transport is required for fetal development and impaired transport has been associated with poor fetal growth. It is well known that placental amino acid transport is mediated by a broad array of specific membrane transporters with overlapping substrate specificity. However, it is not fully understood how these transporters function, both individually and as an integrated s...
