VAGUE This study was conducted to evaluate the influence of proinsulin C-peptide on erythrocyte Na + ,K + -ATPase and endothelial nitric...

...Esther Castaño; PAU Marzabal; F. Javier Casado; Antonio Felipe; Marçal Pastor-Anglada 1. Na+,K+-ATPase activity and its α 1 subunit protein and mRNA in kidney cortex were monitored in rats developing Fanconi syndrome after the administration of maleate. Na+,K+-ATPase activity was significantly...

...Rosa A. Rabini; Giovanna Zolese; Roberto Staffolani; G. Lucarelli; E. Amler; Nelvio Cester; Laura Mazzanti 1. Na + ,K + -ATPase is the membrane enzyme catalysing the active transport of Na + and K + across the plasma membrane of animal cells. A reduced activity of Na + ,K + -ATPase has been...

...Roland J. Ede; Christopher D. Gove; Robin D. Hughes; William Marshall; Roger Williams 1. Previously we have shown that sera from patients with fulminant hepatic failure (FHF) will inhibit partially purified rat brain Na + ,K + -ATPase and sodium efflux from human leucocytes in vitro . Similar...

...Corinna Pippard; P. H. Baylis 1. Total and Na + ,K + -ATPase activities have been measured in sections (10 μm thick) from blocks of rat kidney cultured for 5 h at 37°C, pH 7.5, in Glasgow Eagle's Minimum Essential Medium. 2. Synthetic [arginine]vasopressin ([Arg]VP) stimulated ATPase activity...

... by digoxin, i.e. a much greater rise in plasma rubidium concentrations and a much smaller rise in intra-erythrocytic rubidium concentrations, after the oral load of rubidium chloride. 4. These findings are consistent with widespread reduction in Na + ,K + -ATPase activity in subjects who have taken a loading...
