| cellular basis of brain maturation and acquisition of complex behaviors in salamanders. | the overall bauplan of the tetrapod brain is highly conserved, yet significant variations exist among species in terms of brain size, structural composition and cellular diversity. understanding processes underlying neural and behavioral development in a wide range of species is important both from an evolutionary developmental perspective as well as for the identification of cell sources with post-developmental neurogenic potential. here, we characterize germinal processes in the brain of notop ... | 0 | 29217751 |

| reaction to visual flicker in the newt triturus. | the flicker response curve for the newt triturus viridescens (water phase) has much the same quantitative structure as that found with various fresh-water teleosts at the same temperature (21.5 degrees ). the variability of critical intensity and of critical flash frequency likewise follows the same rules. the cone portion of the f - log i curve is much more widely spread, however. this, and the rather low maximum to which the rod curve rises, produce a considerable overlapping of the two parts ... | 1940 | 19873182 |

| changes in the pattern of nitrogen excretion during the life cycle of the newt. | in the course of its life cycle the eastern newt, triturus (diemyctylus) viridescens, undergoes two metamorphoses, the first from the aquatic larva to the terrestrial red eft; the second, 2 to 3 years later, from the eft to the permanently aquatic and sexually mature adult newt. the pattern of nitrogen exretion changes during both transformations. older larvae excrete about 75 percent of the nitrogen as ammonia, 25 percent as urea; during the first metamorphosis the ratio of ammonia to urea is a ... | 1959 | 14426063 |

| genetic disparity and cancer induction by normal tissue implants in amphibia. | fifty percent of the implants of normal adult triturus cristatus kidney made into the forelimbs of immature but postmetamorphic xenopus laevis hosts initiated the formation of lymphosarcoma at the site of implantation. donor-host genetic disparity as it relates to the intensity of the reaction, when homografts, heterografts, and xenografts are compared, appears to be one of several factors which play a role in the post-embryonic induction of both lymphosarcomas in xenopus laevis and accessory li ... | 1964 | 14207463 |

| lens fiber differentiation and gamma crystallins: immunofluorescent study of wolffian regeneration. | from the adult lens of triturus viridescens, a fraction of proteins was isolated which corresponds to gamma-crystallins of higher vertebrates. tests by immuno-electrophoresis indicate that the antiserum against this fraction reacts with gamma-crystallins, but not with alpha- or beta-crystallins. with this antiserum, an immunofluorescent reagent has been prepared for detection of gamma-crystallins from newts. in the normal lens of the adult newt, these crystallins are detected in fiber cells and ... | 1965 | 14250323 |

| spheroidal and ring nucleoli in amphibian oocytes. patterns of uridine incorporation and fine structural features. | in maturing oocytes of the newt triturus viridescens, the nucleoli undergo a series of morphological changes that are very similar to those described by callan for the axolotl, ambystoma mexicanum. the nucleoli first assume the form of spheroids which then become extended into ring or necklace shapes that are dnase-sensitive; in mature oocytes the nucleoli revert to a spheroidal form. short term in vitro incorporation studies with uridine-(3)h on both species show that rna synthesis occurs in a ... | 1967 | 6055993 |
| isolation and characterization of viruses from the kidneys of rana pipiens with renal adenocarcinoma before and after passage in the red eft (triturus viridescens). | viruses were isolated from kidneys of normal and renal tumor-bearing vermont rana pipiens after subinoculation into red eft newts (triturus viridescens). organs of efts inoculated with viable cell suspensions from four of seven tumor-bearing kidneys yielded virus (lt-1, -2, -3, -4) when inoculated into th-1 (terrapene heart) cell culture. one tumor-bearing kidney also yielded virus (l-4) by direct inoculation into th-1 cells. an additional isolate (l-5) was obtained from 1 of 52 normal vermont f ... | 1968 | 4972302 |

| ribonucleoprotein particles in the amphibian oocyte nucleus. possible intermediates in ribosome synthesis. | studies of the sedimentation properties of rnp(1) material from the nucleus of the amphibian oocyte have indicated (1) that there are few, if any, 78s ribosomes in the nucleus, (2) that there are smaller particles sedimenting at 50-55s and 30s, and (3) that the larger of these is the precursor of the 60s subunit of the cytoplasmic ribosomes. although the nature of the 30s material is not completely clear, it probably includes precursor particles to the 40s ribosomal subunit. heavy (50-55s) parti ... | 1968 | 5645543 |

| development of the neuromuscular junction : ii. cytological and cytochemical studies on the neuromuscular junction of dedifferentiating muscle in the regenerating limb of the newt triturus. | following amputation of the limb of the newt, triturus viridescens, muscle fibers dedifferentiate giving rise to mesenchymal cells. the earliest changes detected in neuromuscular junctions of dedifferentiating muscle fibers are the appearance of a few vacuoles and decrease in density of the terminal axoplasm. later, synaptic vesicles become tightly clustered in the axon termination, and their content appears denser than normal. then, vesicles diminish in number until few are seen in the ending. ... | 1970 | 19866741 |

| leech-repellent property of eastern red-spotted newts, notophthalmus viridescens. | eastern red-spotted newts (notophthalmus viridescens, salamandridae) are rarely attacked by leeches. this protection is not shared by related salamandrids or by ambystoma (ambystomatidae). tetrodotoxin is not the repelent. the immunity of notophthalmus to leech parasitism is probably most significant in its aquatic stages, although the terrestrial efts are also protected. | 1971 | 17779402 |
