... of the first two steps in glucose utilization in the gas gland of Atlantic cod ( Gadus morhua ). Glucose metabolism by isolated gas gland cells was 12- and 170-fold higher, respectively, than that in heart and red blood cells (RBCs) as determined by the production of 3 H 2 O from [2- 3 H]glucose. In the gas...

Glucose metabolism was assessed by the production of 3 H 2 O from [2- 3 H]glucose. Glucose metabolism was 3.5- to 6-fold higher by myocytes from Atlantic cod than...

... glucose induced by CHHBP RNAi reached the same level as that observed in the eyestalk ablation group, suggesting that CHHBP is involved in glucose metabolism regulated by CHH. In addition, compared with the control group, injection of CHH was unable to rescue the decreased glucose levels in CHHBP RNAi...

... an impact on rates of glucose metabolism. The blood glucose level was 2.5 mmol l −1 in Atlantic cod and 0.2 mmol l −1 in short-horned sculpin, respectively. Oxygen consumption, lactate production and glucose utilization were measured in whole blood and related to grams of RBCs. Glucose utilization...

This study investigated glucose metabolism in fasting and developing neonatal elephant seals. Glucose production and glucose cycle activity were measured early (2 weeks) and late(6 weeks...

...S. Panserat; E. Plagnes-Juan; S. Kaushik SUMMARY Rainbow trout ( Oncorhynchus mykiss ) are known to use dietary carbohydrates poorly. One of the hypotheses to explain the poor utilisation of dietary glucose by these fish is a dysfunction in nutritional regulation of hepatic glucose metabolism...

The experiments were designed to investigate the importance of anaerobic glucose metabolism for the secretory activity of the swimbladder and to provide a data set consistent with that on the gas exchange of swimbladder tissue ( Pelster and Scheid, 1992 b...
