Published: 15 July 2011
...Jodie L. Rummer; Colin J. Brauner SUMMARY During a generalized acidosis in rainbow trout, catecholamines are released into the blood, activating red blood cell (RBC) Na + /H + exchange (βNHE), thus protecting RBC intracellular pH (pH i ) and subsequent O 2 binding at the gill. Because...

... physiological and cellular stress responses following a 1 h heat shock in juvenile fish in dominance hierarchies. We measured stress hormone (cortisol and catecholamines) concentrations and blood, brain and liver tissue levels of three heat shock proteins (HSPs), the stress inducible HSP70, the constitutive...

...Bruno Tota; Maria Carmela Cerra; Alfonsina Gattuso Summary In the past 50 years, extensive evidence has shown the ability of vertebrate cardiac non-neuronal cells to synthesize and release catecholamines (CA). This formed the mindset behind the search for the intrinsic endocrine heart properties...

... with a strong preference for aromatic catechol-branched substrates, especially phenylalanine and its derivatives tyrosine and L-DOPA,but not catecholamines. It represents a previously unknown SNF phenotype, and also appears to be the first sodium-dependent B 0 type transporter with a narrow selectivity...

...B. McNeill; S. F. Perry SUMMARY An in situ saline-perfused posterior cardinal vein preparation was used to assess the role of nitric oxide (NO) in the regulation of basal and stimulus-evoked catecholamine secretion from rainbow trout Oncorhynchus mykiss chromaffin cells. Addition of the NO donor...

...Brian McNeill; Colin J. Montpetit; Steve F. Perry SUMMARY The goal of the present study was to assess the catecholamine secretory capabilities of rainbow trout Oncorhynchus mykiss chromaffin cells experiencing desensitization of the nicotinic receptor. It was hypothesized that the potential...

... important) chemoreceptive sites that are not confined to the first gill arch. Plasma catecholamine levels were elevated during hypercarbia,and this response was unaffected by prior gill extirpation. To assess whether the CO 2 chemoreceptors of the first gill arch were sensing water and/or blood P CO 2...

Administration of exogenous catecholamines(10 and 100 nmol kg -1 adrenaline) to fish with intact brains and minimal surgical preparation reduced both respiratory frequency and amplitude,suggesting that humoral release of adrenaline also could not be responsible for the increase in breathing...
