A Cl− Cotransporter Selective for Nh4+ over K+ in Glial Cells of Bee Retina

There appears to be a flux of ammonium (NH(4)(+)/NH(3)) from neurons to glial cells in most nervous tissues. In bee retinal glial cells, NH(4)(+)/NH(3) uptake is at least partly by chloride-dependant transport of the ionic form NH(4)(+). Transmembrane transport of NH(4)(+) has been described previously on transporters on which NH(4)(+) replaces K(+), or, more rarely, Na(+) or H(+), but no trans...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

NH4+ inhibits K-Cl Cotransport in Low K Sheep Red Blood Cells

Parameter Estimation for Models of NH4 Transport by the Renal Na-K-2Cl and K-Cl Cotransporters

An optimization algorithm was used to compute parameter values for kinetic models of NH4 transport by the renal Na-K-2Cl cotransporter (NKCC2) and K-Cl cotransporter (KCC). The optimization method finds model off-binding and translocation rate constants by minimizing the difference between model unidirectional fluxes and published data on NH4 -dependent 86Rb+ uptake by the NKCC and KCC transpor...
