... Trachemys scripta elegans , a species undergoing strong metabolic suppression when cold and anoxic. In warm normoxic turtles, free H 2 S was higher in red blood cells (RBCs) and kidney (∼9–10 µmol l −1 ) than in brain, liver and lung (∼1–2 µmol l −1 ). These values overall aligned with the tissue H 2 S...

...William R. Driedzic; Kathy A. Clow; Connie E. Short Energy metabolism was assessed in red blood cells (RBCs) from Atlantic cod and short-horned sculpin, two species that have markedly different levels of blood glucose. The objective was to determine whether the level of extracellular glucose has...

... and smaller red blood cells. However, these differences disappeared after 6 weeks of acclimation to normoxia at low altitude. The measured traits were also indistinguishable between the F 1 progeny of highland and lowland mice, indicating that there were no persistent differences in phenotype that could...

... conducted until the point of isotopic steady state with a diet. We kept six leopard sharks in captivity for 1250 days, measured their growth, and serially sampled plasma, red blood cells and muscle for stable carbon and nitrogen isotope analysis. A single-compartment model with first-order kinetics...

...A. J. Esbaugh; B. L. Tufts SUMMARY Carbonic anhydrase (CA) is a multi-functional enzyme that catalyzes the hydration/dehydration of carbon dioxide. In the red blood cell (rbc), CA is necessary to facilitate the transport of carbon dioxide out of the body. Results from earlier biochemical studies...

.... The objective of the current study was to determine if branchial CA activity in rainbow trout was the result of a general cytoplasmic CA isozyme, with kinetic properties,tissue distribution and physiological functions distinct from those of the red blood cell (rbc)-specific CA isozyme. Isolation and sequencing...
