Erythrocytes Blood volume Interstitial fluid volume Allometry When a human body enters microgravity during a space flight, gravity ceases to pull blood to the lower part of the body, causing blood and other body fluids to redistribute. This fluid shift is manifest in the well-documented decrease...

... the respiratory chain was blocked, adrenergic stimulation increased the rates of ATP consumption and glycolysis of red blood cells. Moreover, adrenergic stimulation of deoxygenated erythrocytes also increased cell volume but did not enhance glycolysis or ATP consumption, and the cells remained swollen. Our...

..., methyl amines), which are lost from cells in response to swelling, share a single pathway having the characteristics of an anion channel. However, the molecular identity of this pathway remains to be established. It has been suggested that the erythrocyte anion exchanger (AE1) or some AE1-related...

Human erythrocyte membrane rigidity is only weakly dependent on temperature, but membrane viscosity is more strongly so ( Hochmuth et al . 1980 ). If trout red cell membrane viscosity (not investigated here) also has a strong temperature...

.... These characteristics are in agreement with those reported for the GLUT-1 glucose carrier of human and Japanese eel erythrocytes. These cells also contained a saturable carrier for L-lactate in the concentration range 0–10 mmol l −1 ( K m 6.74±0.36 mmol l −1 , J max 2.29±0.09 mmol lactate l −1 cell water min −1...

...Steinar M. Thoroed; Margrethe Soergaard; Edward J. Cragoe, JR; Kjell Fugelli ABSTRACT Stimulation of flounder erythrocytes by noradrenaline under isosmotic conditions (330 mosmol kg -1 ) and physiological Na + concentration (113 mmol l -1 ) caused swelling of the cells. The EC 50 of this cell...

...S. M. Thoroed; K. Fugelli ABSTRACT 95 % of the Na + -independent influx of taurine in flounder erythrocytes at normal osmolality (330 mosmol kg −1 ) and 0.30 mmol l −1 taurine was mediated by a saturable system ( V max =0.689 nmol g −1 dry mass min −1 ; K m =0.47 mmol l −1 ). The influx...

...Martha Kaloyianni; Basile Michaelidis; Katerina Moutou ABSTRACT The effects of adenosine and inosine on Rana ridibunda erythrocyte metabolism were studied. Adenosine can be metabolized by Rana ridibunda erythrocytes as a carbon source for glycolysis to maintain ATP levels, whereas neither inosine...
