... transporters currently ascribed to the renal collecting duct. Here, we re-examine the effect of bafilomycin A 1 , an inhibitor of vacuolar (V-type) H + -ATPases, on acid secretion by intact isolated bladders from Pseudemys scripta turtles. Serosal-side bafilomycin had no effect on the transepithelial...

... − –H + equilibration in blood-perfused turtle ( Pseudemys scripta ) lungs. Turtle lungs perfused in situ with red cell suspensions containing inhibitors of erythrocyte anion exchange and/or pulmonary and red cell carbonic anhydrase produced significant postcapillary blood and pH disequilibria, while...

... pulmonale is functionally separated from the rest of the ventricle during systole. The purpose of this study was to test the two principal hypotheses in a turtle, Pseudemys scripta , after inducing a right-to-left shunt by electrical stimulation of the vagus nerve. Animals were anaesthetized with sodium...
