... that at least some teleosts have a third option: to reversibly remodel the gill morphology. Studies have shown that the lamellae of crucian carp Carassius carassius gills are embedded in a cell mass during normoxic conditions or at low temperature,while much of this cell mass dies off in hypoxia and at higher...

... acclimation as well as in hypoxia adaptation in poikilotherms, we studied HIF-1 DNA binding activity and HIF-1α expression in normoxia and during hypoxia (0.7 mg l –1 O 2 ) in crucian carp at temperatures of 26, 18 and 8°C. Temperature had a marked influence on HIF-1 in normoxia. Although HIF-1α mRNA levels...

...Jørund Sollid; Roy E. Weber; Göran E. Nilsson SUMMARY We have previously found that the gills of crucian carp Carassius carassius living in normoxic (aerated) water lack protruding lamellae,the primary site of O 2 uptake in fish, and that exposing them to hypoxia increases the respiratory surface...

...Matti Vornanen ABSTRACT A patch-clamp analysis of L-type Ca 2+ current in ventricular myocytes of cold- and warm-acclimated rainbow trout ( Oncorhynchus mykiss ) and crucian carp ( Carassius carassius ) hearts was performed. Trout were acclimated at 4 and 17°C and carp at 4 and 24°C for a minimum...

...Dan Johansson; Göran E. Nilsson ABSTRACT The crucian carp ( Carassius carassius L.) is one of the most anoxia-tolerant vertebrates known, being able to maintain ion homeostasis in its brain for many hours of anoxia. This study aims to clarify the importance of glycolysis during anoxia and also...

...Göran E. Nilsson; Peter Rosén; Dan Johansson ABSTRACT The crucian carp ( Carassius carassius L.) is one of the most anoxia-tolerant fishes. An important strategy used by the crucian carp to survive anoxia is to lower its rate of energy consumption. Anoxia-tolerant fish are known to utilize...

...G. E. Nilsson ABSTRACT Crucian carp ( Carassius carassius L.), which are extremely anoxia-tolerant, were exposed to 17 days of anoxia at 8 °C. One group of fish was transferred to normoxic water for 1–8 h immediately after the anoxic period. All the eight amino acids measured in brain (including...

...E. Nilsson Göran ABSTRACT In the brain, oxygen is required for both the synthesis and the degradation of monoamine transmitters, so monoaminergic systems can be expected to be strongly affected by anoxia. However, crucian carp ( Carassius carassius L.) may survive anoxia for many days or even weeks...
