| mauthner neurons survive metamorphosis in anurans: a comparative hrp study on the cytoarchitecture of mauthner neurons in amphibians. | giant medullary neurons were revealed in adult xenopus laevis and rana esculenta following hrp injections to the spinal cord. these neurons were identified as mauthner neurons because (1) they have the same position and orientation as the larval mauthner neurons, i.e., they lie at the level of the viiith nerve root. (2) they have two large dendritic trees that for each species are similar to those of the larval mauthner neurons, (3) they are clearly distinguishable from other large reticular neu ... | 1986 | 3081602 |
| a new species of the genus <i>paramesotriton</i> (caudata: salamandridae) from fujian, southeastern china. | new amphibian species have been constantly discovered throughout southern china, including from areas close to heavily populated cities that remain poorly surveyed for amphibian diversity. we describe a new species of the newt genus paramesotriton from fujian, a developed province on the southeastern coast of mainland china. the mitochondrial genealogy suggests that the new species is the sister taxon to paramesotriton hongkongensis, separated by an uncorrected pairwise distances of 5.8% at the ... | 2016 | 27988548 |
| tetrodotoxin in asian newts (salamandridae). | tetrodotoxin (ttx) and its analogues occur in a wide range of marine animals but also in terrestrial vertebrates such as frogs, toads and newts. despite numerous studies on ttx in new world newts (notophthalmus viridescens, taricha spp.), few data only exist for asian newts. methanolic extracts of newts from china (cynops orientalis, pachytriton labiatus, paramesotriton chinensis), vietnam (paramesotriton deloustali, p. guangxiensis), and laos (laotriton laoensis) were analyzed by liquid-chromat ... | 2017 | 28528177 |
