Definition of tetrodotoxin in English:

tetrodotoxin

noun ˌtɛtrədə(ʊ)ˈtɒksɪnteˌtrōdəˈtäksin

mass noun

A poisonous compound present in the ovaries of certain pufferfishes. It is a powerful neurotoxin.
河鲀毒素，河豚毒素
Example sentencesExamples
- Since failures were not observed when selecting fluorescent spots lying in a row on top of a neuronal process, in later experiments 0.5 M tetrodotoxin was applied to prevent rundown, and the destaining step was omitted.
- Calcium currents were isolated by replacing extracellular sodium with TEA and adding tetrodotoxin and other K + channel blockers.
- The highly selective sodium channel blocker, tetrodotoxin has been instrumental in characterization of voltage-gated sodium channels.
- Newts of the genus Taricha possess large quantities of tetrodotoxin in their skin and other tissues.
- Research is now being conducted into the properties of the fugu's lethal poison, tetrodotoxin at six centres across Canada, much of it in Montreal.
- External solution included 0.6 M tetrodotoxin to block any small endogenous sodium current.
- The poison in fugu is neurotoxin tetrodotoxin and although it is not always fatal, it can cause an unpleasant death.
- The approach is illustrated with data from a predator-prey arms race between garter snakes and newts that operates through the interface of tetrodotoxin and resistance to it.
- The liver and reproductive organs of the puffer fish contain tetrodotoxin, an extremely powerful nerve poison.
- Furthermore, application of tetrodotoxin, which blocks impulse generation in the cardiac ganglion, had no effect on the larval heart but stopped the heart of older juveniles from beating.
- My doctoral research focuses on those two genera; the birds carry batrachotoxin, not tetrodotoxin, a very different chemical.
- The effects of the nitric oxide synthase inhibitor on the response to histamine were mimicked by vagotomy or selective nerve blockade with tetrodotoxin.
- If neural activity is blocked during development by the injection of tetrodotoxin, ocular dominance columns do not develop, and the inputs from the two eyes into the visual cortex remain mixed.
- Brachycephalus ephippium is bright orange, and some of its skin glands secrete tetrodotoxin.
- Similarly, tetrodotoxin is another blocker of certain voltage-gated Na+ channels that occurs in numerous species of animals, including the puffer fish, Tetraodontidae spp., and newts, Taricha spp. and Cynops spp.
- That's enough to thwart the tetrodotoxin and keep the muscles going - until either prey or predator evolves a new weapon.
- After tetrodotoxin was identified in puffers, it started turning up in a variety of places around the globe.
- However, only trace amounts of tetrodotoxin have been found in balloonfish, mainly concentrated in the ovaries.
- Drugs presently available act on sodium channels sensitive to tetrodotoxin and thus have widespread side effects in the heart and central nervous system.
- Some gobies even rely on chemical protection, producing a poison called tetrodotoxin, which also occurs in pufferfishes and species of salamander.

Origin

Early 20th century: from modern Latin Tetrodon (former genus name, from Greek tetra- 'fourfold' + odous, odont- 'tooth') + toxin.
