THYROIDAL METABOLISM OF IODINE IN THE SHARK SCYLIORHINUS (SCYLLIUM) CANICULA
Endocrinology, 1952THE physiological role of the thyroid gland in the fishes remains largely enigmatic, since most research has demonstrated a lack of response of oxygen consumption to thyroidal hormone (Root and Etkin, 1937; Hasler and Meyer, 1942; Smith and Everett, 1943) in this group of animals.

Cloning of iNOS in the small spotted catshark (Scyliorhinus canicula)
Developmental & Comparative Immunology, 2006The first cartilaginous fish iNOS gene has been cloned in the small spotted catshark, Scyliorhinus canicula. The cDNA was 4568 bp long, with a 3375 bp open reading frame encoding a protein of 1125 amino acids and a predicted molecular mass of 127.8 kDa.

Evidence of collagen in the egg capsule of the dogfish, scyliorhinus canicula
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976Abstract 1. 1. The amino acid composition of the dogfish egg capsule and X-ray patterns of samples are conclusive regarding the evidence of collagen in this structure. 2. 2. Labelling of the egg capsule secreting gland (nidamental gland) with radioactive proline demonstrates that this collagen is secreted by very narrow cells of tubules ...

Coronary myointimal lesions in the dogfish shark Scyliorhinus canicula
Journal of Comparative Pathology, 1991Proliferative lesions have been found in the coronary arteries of five specimens of dogfish shark (Scyliorhinus canicula). Three specimens lacked the internal elastic membrane and had a diffuse thickening of the intima obliterating most of the vascular lumen in several intramyocardial branches.

Development of the lymphomyeloid system in the dogfish, Scyliorhinus canicula
Developmental & Comparative Immunology, 1993Previous studies on the morphology of the lymphomyeloid tissues in the dogfish, Scyliorhinus canicula, have been confined to adults. This study was restricted to the structure and functioning of the developing immune system in embryonic and post-hatch dogfish. A major feature of the developing immune system in S.

Cutaneous O2 and CO2 exchanges in the dogfish, Scyliorhinus canicula
Respiration Physiology, 1982Total and cutaneous O2 and CO2 exchanges were studied in the unanesthetized, spinalectomized dogfish, Scyliorhinus canicula. Total oxygen uptake and carbon dioxide output were measured with an open flow respirometer. Cutaneous fluxes of O2 and CO2 were determined on the tail, confined in the posterior compartment of a two-chambered respirometer, in ...

Incorporation of [1-14C]-glucosamine in a selacian Scyliorhinus canicula
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1973Abstract 1. 1. d -[1- 14 C]-Glucosamine was injected into the hearts of small dogfish ( Scyliorhinus canicula ) in order to study its incorporation into serum glycoproteins, liver glycoproteins and glycogen. 2. 2. The radioactive label, in its free form, disappeared rather rapidly from the blood and, after a delay, radioactivity was found ...

Ultrastrictural Study of the Posterior Cornea of the Dogfish, Scyliorhinus canicula
Cornea, 1987The cornea of Elasmobranchs remains transparent and exhibits a remarkable resistance against swelling when deprived of its endothelium. Sutural fibers, which traverse the corneal stroma anteroposteriorly, may be responsible for this property. We studied the structure of the cornea of Scyliorhinus canicula L., a galeiform Elasmobranch, with special ...

Effects of hypophysectomy on vitellogenesis in the elasmobranch Scyliorhinus canicula L
General and Comparative Endocrinology, 1978Abstract The effects of total hypophysectomy on vitellogenesis in adult female Scyliorhinus canicula were investigated by injection of 32 P-phosphate 5 days after operation. The rate of plasma vitellogenin formation was not significantly altered by the operation, but removal of vitellogenin from the plasma was delayed relative to controls. Similar

Spectral sensitivity of the dogfish shark (Scyliorhinus canicula)
Fish Physiology and Biochemistry, 2006The action spectrum of the electroretinographic (ERG) b-wave and the unmasked late receptor potential (LRP) were measured under a variety of conditions (isolated eyecup, detached retina, b-wave recording in fresh preparations, LRP measurements after low-temperature aging, dark and light adaptation).
