.... Branchial Na + ,K + -ATPase activity was much higher in SW gills, but could not be activated by NH 4 + . Overall, the more effective response of SW trout was explained by differences in physical chemistry between SW and FW, which greatly reduced the plasma NH 3 tension gradient for NH 3 entry, as well...

... for a successful terrestrial invasion. Crabs can actively uptake or excrete ions upon salinity change, and the gills play a major role among the osmoregulatory organs. Several enzymes are involved in the osmoregulatory process, including Na + ,K + -ATPase and V-type H + -ATPase (V-H + -ATPase). Na + ,K + -ATPase...

... are functionally similar in seawater, but in freshwater the gills actively absorb Na + but not Cl – , whereas the opercular epithelium actively absorbs Cl – but not Na + . These differences in freshwater physiology are likely due to differences in absolute levels of gene expression (measured using real-time PCR...

... in the brain of five mammalian and eight avian species ranging in size from 30 g mice to 280 kg cattle and 13 g zebra finches to 35 kg emus, respectively. Sodium pump(Na + ,K + -ATPase) activity was higher in the smaller species and showed a significant allometric decline with body mass in both the mammals...

... potassium was not significantly decreased in the D flies during desiccation but was reduced(i.e. excreted) in the C flies; hence, we suggest that the potassium content paralleled tissue water level. Hemolymph Na + content of the C flies dropped significantly (84%reduction) during the initial 8 h ( P...
