Example Sentences:
(1) A preliminary hypothesis is put forth that explains the apparent constancy of the cephalic vascular system of ophidians in terms of possible constraints due to cranial kinesis.
(2) This preliminary investigation has brought to light differences in GC percentages and in the shape of melting curves between chelonian DNA and that from saurians and ophidians.
(3) The gross and ultrastructural heterogeneity of the organisation of the ophidian lung is illustrated and the dearth of pulmonary morphological data in this taxon is pointed out.
(4) Thus, at variance with the situation in the mammalian SCO, in the ophidian SCO most of the secretion is stored in secretory granules rather than in dilated cisternae of the rough endoplasmic reticulum.
(5) Thus, it may be concluded that the pineal gland of this ophidian participates in the regulation of seasonal testicular cycle, probably via the hypothalamo-hypophyseal axis, and hence the effects of pinealectomy are seasonal and a reproductive phase-dependent phenomenon.
(6) A wide variety of ophidian venoms (crotaline, viperine, elapid, hydrophid and colubrid) were examined for the presence of this toxin using Ouchterlony, immunoelectrophoresis, ELISA and Western transfer.
(7) A new ophidian kidney preparation is described which allows the measurement of glomerular arteriolar diameters, glomerular blood flow, and glomerular capillary pressure in real time.
(8) In this method amino acids produced by hydrolysis of peptides are oxidized by ophidian L-amino acid oxidase and the hydrogen peroxide produced during reoxidation of the reduced enzyme is estimated spectrophotometrically.2.
(9) This is the first study to reveal an ophidian response to internal chemicals of potential prey organisms.
(10) The DNA base composition was studied in 9 reptilian species (4 chelonians, 3 saurians, and 2 ophidians) by the thermal denaturation method.
(11) The primary and secondary elements of the cephalic vascular system in some sea snakes are similar to those of the generalized ophidian pattern.
(12) In embryos of Snake-like Reptiles (Anguis fragilis) and of Ophidians (Tropidonotus, Python), the lay-out of motor neuroblast in the ventral horns of the spinal cord, in the brachial and the lumbar regions differs from the one observed in the same regions of embryos of tetrapod Reptiles (Lacerta viridis).
(13) The cell masses of the diencephalon of Amphisbaena darwini heterozonata are studied and confronted with those of other reptiles, specially with the burrowing ophidian Typhlopidae.
(14) In seven ophidian species, in which the female is the heterogametic sex, H-Y was detected in the female; and in three species of Ranidae in which the male is heterogametic, it was detected in the male.
(15) For 3 enzymes,ophidian L-amino acid oxicase, ATPpyrophosphatase, and acetylcholinesterase, some of the problems pertaining to venom toxicity are discussed.
(16) Finally, the ophidian saccular lung is postulated to assist in maintenance of high tidal volume.
(17) Some of these procedures were also applied to the ophidian and canine SCO.
