... the involvement of a hypertonically induced Na + /H + exchanger and an accompanying Cl − /HCO 3 − exchanger. Both the hypertonically induced Na + influx and the RVI were blocked by oxygenation of shrunk cells. The β-adrenergic agonist isoproterenol also strongly activated a Na + influx and caused cell swelling...

... 1997 protein phosphorylation K + /Cl − cotransport Na + /H + antiport volume regulation oxygenation Animal cells are surrounded by a thin and flexible plasma membrane which, lacking structural rigidity, is unable to withstand hydrostatic forces. As a result, cells exist in osmotic...

.... Deoxygenated blood taken by caudal puncture exhibited lower viscosities than oxygenated samples at low shear rates, whereas the opposite was true at high shear rates. However, blood from cannulated trout had similar viscosities in its deoxygenated and oxygenated states. In the deoxygenated state, addition...

...Hans-Otto Pörtner ABSTRACT The in vitro oxygen-binding characteristics of haemocyanin were investigated in whole blood of two species of pelagic squid, Illex illecebrosus and Loligo pealei . pH-independent Haldane coefficients (ΔHCO 3 − /ΔHcyO 2 ) (where HcyO 2 is haemocyanin-bound oxygen) slightly...
