Example Sentences:
(1) In other dogfish, glomerular filtration rate, urine flow, and Na and K excretory rates were measured for 3 days following implantation of desoxycorticosterone (DOCA), adrenocorticotropin (ACTH), or spironolactone; a control group was given no drug.
(2) The results showed that dogfish lenses developed superficial opacities due to near-UV exposure.
(3) The N-terminal tridecapeptide sequence was identical with the proposed structure of dogfish alpha-melanocyte-stimulating hormone (alpha-MSH).
(4) The "apo" lactate dehydrogenase structure was solved by use of the known apo-M4 dogfish lactate dehydrogenase molecule as a starting model.
(5) In addition, the interrenal cells of the common dogfish are strikingly rich in microfilament-like inclusions.
(6) In contrast to dogfish sharks, stringrays with high spinal transections do not locomote.
(7) It is concluded that, despite a broader specificity, the activity spectrum of dogfish enzyme is, in many respects, similar to that of calf chymosin.
(8) Tissue from the digitiform rectal gland of the spiny dogfish, Squalus acanthias, was fixed briefly by formaldehyde perfusion and studied for the specificity and localization of p-nitrophenyl phosphatase (NPP'ase) activity.
(9) A melanocyte-stimulating hormone (MSH) has been isolated from extracts of the neurointermediate lobe of the pituitary of the dogfish Squalus acanthias by gel-filtration and ion-exchange chromatography.
(10) Initial-rate studies were made of the oxidation of L-glutamate by NAD+ and NADP+ catalysed by highly purified preparations of dogfish liver glutamate dehydrogenase.
(11) Aqueous humor dynamics were studied in the dogfish, Squalus acanthias, using isotopically labeled inulin, Na+, Cl-, and HCO-3.
(12) The spiracular sense organs of the little skate, Raja erinacea, and the smooth dogfish, Mustelus canis, respond to movements of the hyomandibula-cranial joint.
(13) The primary structure of glucagon isolated from the intestine of the common dogfish, Scyliorhinus canicula, was established as H S E G T F T S D Y S K Y M D N R R A K D F V Q W L M N T. The peptide shows four substitutions compared with human glucagon: Glu-3 for Gln, Met-14 for Leu, Asn-16 for Ser and Lys-20 for Gln.
(14) Glycogen debranching enzyme (4-alpha-glucanotransferase amylo-1,6-glucosidase, EC 2.4.1.25 + 3.2.1.33) was purified 140-fold from dogfish muscle in a rapid, high-yield procedure that takes advantage of a strong binding of the enzyme to glycogen, and its quantitative adsorption to concanavalin A-Sepharose only when the polysaccharide is present.
(15) The skin of the dogfish in an exchanger for oxygen supplying 10% of oxygen requirements of other organs of the body in these experimental conditions (t = 13 degrees C).
(16) In marine fish (herring, dogfish shark, hagfish) FAO activities were all less than 15% that of rats and undetectable in hagfish.
(17) The dogfish enzyme has a higher pH optimum (8.5) and a broader spectrum of activity above and below its optimum than a commercial porcine lipase preparation (optimum, 7.5).
(18) The physiological effects of dogfish GnRH included the release of not only gonadotropin but also growth hormone from goldfish pituitary fragments.
(19) In this experiment, testicular tissues from different dogfish corresponding to the zones of lobules with spermatogonia (A), spermatocytes (B), early spermatids (C) and late spermatids (D) were dissected out and pooled.
(20) The vascular capacitance and volume distensibility of the isolated dogfish gut and segments of dogfish arteries and veins were investigated.
