Dogfish hair cells sense hydrostatic pressure
Nature, 2002Many marine invertebrates and fish respond to hydrostatic pressure in order to regulate their depth and synchronize their behaviour to tidal cycles. Here we investigate the effect of hydrostatic pressure on the vestibular hair cells located in the labyrinth of the dogfish Scyliorhinus canicula, and find that it modulates their spontaneous activity and ...

Gelatin has been prepared from the skin and skeleton (separately) of the dogfish, Squalus suckleyi. The gelling and melting points of a 10% solution were 15 and 22 °C respectively, for gelatin from skin, and 14 and 23 °C for that from skeleton. The skin gelatin contained 16.3%, total nitrogen, 6.4% hydroxyproline, and 0.28% tyrosine. The corresponding

Cardiovascular Actions of Dogfish Urotensin I in the Dogfish,Scyliorhinus canicula
General and Comparative Endocrinology, 1998A synthetic replicate of dogfish urotensin 1 (U-I), a 41-amino-acid residue peptide isolated from an extract of the caudal spinal cord region of the European spotted dogfish Scyliorhinus canicula was prepared in order to study its cardiovascular actions in the species of origin.

Cardiovascular actions of dogfish urotensin II in the dogfish Scyliorhinus canicula
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1993Bolus injections of synthetic dogfish urotensin II (0.1-1.0 nmol) into the celiac artery of the conscious dogfish Scyliorhinus canicula (n = 8) resulted in sustained and dose-dependent increases in arterial blood pressure and pulse pressure. A maximum rise in mean arterial pressure of 10.5 +/- 1.2 mmHg (equivalent to 38.6 +/- 4.2% over mean basal ...

Swelling properties of dogfish cornea
Experimental Eye Research, 1969In the dogfish stroma the normal hydration was approximately 3·2 mg H 2 O/mg dry weight—slightly less than the normal value obtained previously for mammalian stroma. At this hydration the swelling pressure was zero. When fluid was removed from the stroma, a swelling pressure was obtained which varied depending upon the composition of the test solution.

Structural proteins of dogfish skeletal muscle
Biochemistry, 1975As part of a study on the evolutionary aspects of control mechanisms, a number of structural muscle components from the Pacific dogfish (Squalus acanthias) are described. These include troponin, tropomyosin, actin, and myosin. Troponin (mol wt 108.000) was resolved into its constitutive subunits, repeated by a 20,500 mol wt fragment which binds 2 mol ...

Ultrastructure of the dogfish adenohypophysis
Cell and Tissue Research, 1978Granular hormone-producing cells and agranular cells (stellate cells, including giant and pericavitary cells) were electron microscopically studied in the hypophysis of the small spotted dogfish (Scyllium canicula) up to several months after hatching. Comparisons of results obtained in embryos, newly-hatched fish and adults show an increase of the mean

Amino acid sequence of dogfish trypsin
Biochemistry, 1975The amino acid sequence of pancreatic trypsin from the spiny Pacific dogfish (Squalus acanthias) has been determined and compared with the sequences of bovine and porcine trypsin. Dogfish trypsin contains one less amino acid residue (222) than the other two enzymes. Two-thirds of the residues in corresponding positions in dogfish and bovine trypsin are
