Aging of the erythrocyte. 23. Changes in the permeation of spin-labeled electrolytes

, : Aging of the erythrocyte. 23. Changes in the permeation of spin-labeled electrolytes. American Journal of Hematology 14(4): 377-379

The transport of spin-labeled anions and cations was studied in bovine erythrocyte fractions of various ages. Permeation of a spin-labeled anion, 3-carboxy-2,2,5,5-tetramethylpyrrolidine-1-oxyl into the cells was found to be significantly slower in older cells, suggesting a functional impairment of the band 3 protein of the erythrocyte membrane during red cell aging in vivo.

Shortening of the tail fin of frog larvae is stimulated in the early stages of development and is retarded in the late stages by taurine. The effect of triiodothyronine [T3] on metamorphosis is antagonized by taurine. This antagonistic effect is d...

In the karstic upper Floridan aquifer, surface water flows into conduits of the groundwater system and may exchange with water in the aquifer matrix. This exchange has been hypothesized to occur based on differences in discharge at the Santa Fe Ri...
