...) and SO 4 2– -enriched seawater (30 mmol l –1 ). Unlike Mozambique tilapia and chum salmon, Japanese eels maintained higher plasma SO 4 2– concentration in freshwater (6.2±2.3 mmol l –1 ) than in seawater (0.7±0.1 mmol l –1 ). We then analyzed the whole-body SO 4 2– budget using 35 SO 4 2– . 35 SO 4 2...

... produced by heterospecifics, we investigated possible differences in the odour of bile between the sexes and among different species – the eel ( Anguilla anguilla ), goldfish ( Carassius auratus ) and Mozambique tilapia ( Oreochromis mossambicus ) – using the electro-olfactogram (EOG). We also identified...

...Vincent van Ginneken; Erik Antonissen; Ulrike K. Müller; Ronald Booms; Ep Eding; Johan Verreth; Guido van den Thillart SUMMARY One of the mysteries of the animal kingdom is the long-distance migration(5000–6000 km) of the European eel Anguilla anguilla L. from the coasts of Europe to its spawning...

...-transporting epithelium,the intestine of the euryhaline teleost Anguilla anguilla . Eel intestinal epithelium, when symmetrically bathed with Ringer solution,develops a net Cl - current giving rise to a negative transepithelial potential at the basolateral side of the epithelium. The eel intestinal epithelium...

...Eric D. Tytell SUMMARY Simultaneous swimming kinematics and hydrodynamics are presented for American eels, Anguilla rostrata , swimming at speeds from 0.5 to 2 L s -1 . Body outlines and particle image velocimetry (PIV)data were collected using two synchronized high-speed cameras, and an empirical...

...Eric D. Tytell; George V. Lauder SUMMARY Eels undulate a larger portion of their bodies while swimming than many other fishes, but the hydrodynamic consequences of this swimming mode are poorly understood. In this study, we examine in detail the hydrodynamics of American eels ( Anguilla rostrata...

...Toshihiro Uesaka; Keiichi Yano; Seiji Sugimoto; Masaaki Ando SUMMARY A new glucagon-like peptide was isolated from the intestine of the eel Anguilla japonica . The primary structure was determined by sequence analysis after cleavage with lysyl endopeptidase, quantitative amino acid analysis...

.... To examine the mechanisms by which the body in particular contributes to thrust production, we chose eels, which have no pronounced tail fin and hence are thought to generate all their thrust with their body. We investigated the interaction between body movements and the flow around swimming eels using two...

..., we assessed the effects of NO on the cardiac performance of the eel Anguilla anguilla . We examined basal cardiac performance (at constant preload, afterload and heart rate), the effects of cholinergic stimulation and the Frank–Starling response (preload-induced increases in cardiac output...

...Michaël Theron; François Guerrero; Philippe Sébert ABSTRACT Previous studies have suggested that the efficiency of oxidative phosphorylation in the freshwater eel ( Anguilla anguilla ) is increased after acclimation to high hydrostatic pressure. Analysis at atmospheric pressure of the respiratory...

...Tiziano Verri; Michele Maffia; Antonio Danieli; Martina Herget; Uwe Wenzel; Hannelore Daniel; Carlo Storelli ABSTRACT H + /peptide cotransport in brush-border membrane vesicles (BBMVs) from eel ( Anguilla anguilla ) intestine was studied by measuring D-[ 3 H]-phenylalanyl-L-alanine uptake...

...Gary B. Gillis ABSTRACT Eels ( Anguilla rostrata ) are known to make occasional transitory excursions into the terrestrial environment. While on land, their locomotor kinematics deviate drastically from that observed during swimming. In this study, electromyographic (EMG) recordings were made from...

... eels, Anguilla anguilla . Transepithelial Ca 2+ inflow in the gills increased 2 weeks after transfer of the eels from fresh water to sea water and after stanniectomy. Neither of these treatments changed the membrane density or the affinity of the Ca 2+ -extrusion mechanisms (Ca 2+ -ATPase and Na + /Ca...

... + /K + -ATPase activity. An enriched preparation of basolateral membranes was prepared from the gills of freshwater- and seawater-acclimated American eel ( Anguilla rostrata ). Phospholipid class distribution, fatty acyl chain compositions and cholesterol contents were determined. Phosphatidylcholine...

... were investigated using saline- or blood-perfused swimbladder preparations of the freshwater European eel Anguilla anguilla . While β-adrenergic vasodilation was not detectable, a bolus injection of adenosine (100 μl, 10 −7 mol l −1 ) and application of VIP (10 −7 mol kg −1 ) caused a significant...

...A. Bicho; H. Gil Ferreira; K. Gil Ferreira ABSTRACT Patches of freshly isolated epithelial cells from eel Anguilla anguilla intestine bathed by the same solution on both sides in the cell-attached configuration had conductances of 57.0±1.8 pS (for positive voltages) and 13.3±0.7 pS (for negative...

... about either of these areas in eels, which represent an extreme body form among fishes and utilize a mode of locomotion found at one end of the undulatory spectrum (anguilliform locomotion). To assess how this swimming mode and body form influence the neuromuscular control of swimming, I recorded...

...Colin J. Brauner; Roy E. Weber ABSTRACT H + titrations were conducted on the separated haemoglobin components of eel Anguilla anguilla in both the oxygenated and deoxygenated states. In anodic haemoglobin, the addition of GTP, and to a lesser extent Cl − , increased the magnitude of the Haldane...

...Gary B. Gillis ABSTRACT Historically, the study of swimming eels (genus Anguilla ) has been integral to our understanding of the mechanics and muscle activity patterns used by fish to propel themselves in the aquatic environment. However, no quantitative kinematic analysis has been reported...

...Kenneth J. Rodnick; John R. Bailey; Jenny L. West; Alison Rideout; William R. Driedzic ABSTRACT We investigated the effects of anoxia and contractile activity on glucose uptake and the intracellular location of hexokinase in cardiac muscle of the American eel Anguilla rostrata . Uptake of 2...
