... urea transporter (UT) in the kidney of the dogfish Triakis scyllia . We isolated a cDNA encoding a UT that is homologous to the facilitative UT cloned from another dogfish species, Squalus acanthias . The Triakis UT mRNA is abundantly expressed in the kidney, while low levels of expression were...

...F. Lou; N. A. Curtin; R. C. Woledge SUMMARY Maximum isometric tetanic force produced by bundles of red muscle fibres from dogfish, Scyliorhinus canicula (L.), was 142.4±10.3 kN m -2 ( N =35 fibre bundles); this was significantly less than that produced by white fibres 289.2±8.4 kN m -2 ( N =25...

... the dogfish Scyliorhinus canicula . Heat production was also measured because the sum of work and heat is equivalent to the energy cost of the contraction (ATP used). These energy fluxes were evaluated in contractions with constant-velocity shortening either during stimulation or during relaxation. The muscle...

... fibres isolated from dogfish Scyliorhinus canicula were used to characterize the force–velocity relationship of the contractile component (CC) and the stress–strain relationship of the passive, elastic component (SEC) in series with the CC. A simple model of the time course of crossbridge activation...

...N. A. Curtin; M. J. Kushmerick; R. W. Wiseman; R. C. Woledge ABSTRACT Recovery after contraction of white muscle fibres of dogfish was investigated using 31 P-NMR and measurements of heat production. The muscle fibres were stimulated to perform either a single isometric tetanus or a series of brief...

...F. Lou; N. A. Curtin; R. C. Woledge ABSTRACT The energetic cost of activation was measured during an isometric tetanus of white muscle fibres from the dogfish Scyliorhinus canicula . The total heat production by the fibres was taken as a measure of the total energetic cost. This energy consists...

... from the SR. This apparent difference in myocardial excitation–contraction (E–C) coupling was investigated further by determining DHPR and RyR densities in ventricular homogenate preparations from rat, trout, dogfish and hagfish. DHPR B max values (means ± S.E.M.) were highest in rat (0.30±0.01 pmol mg...
