Noradrenergic And Specific Serotonergic Antidepressant
Noradrenergic and specific serotonergic antidepressants (NaSSAs) are a class of psychiatric drugs used primarily as antidepressants. They act by antagonizing the α2-adrenergic receptor and certain serotonin receptors such as 5-HT2A and 5-HT2C, but also 5-HT3, 5-HT6, and/or 5-HT7 in some cases. By blocking α2-adrenergic autoreceptors and heteroreceptors, NaSSAs enhance adrenergic and serotonergic neurotransmission in the brain involved in mood regulation, notably 5-HT1A-mediated transmission. In addition, due to their blockade of certain serotonin receptors, serotonergic neurotransmission is not facilitated in unwanted areas, which prevents the incidence of many side effects often associated with selective serotonin reuptake inhibitor (SSRI) antidepressants; hence, in part, the "specific serotonergic" label of NaSSAs. List of NaSSAs The NaSSAs include the following agents: * Aptazapine (CGS-7525A) * Esmirtazapine (ORG-50,081) * Mianserin (Bolvidon, Norval, Tolvon) * Mirt ...

Nassa (gastropod)
''Nassa'' is a genus of sea snails, marine gastropod mollusks in the subfamily Rapaninae of the family Muricidae, the murex snails or rock snails. Taxonomy The history of the name ''Nassa'' is rather confused, because the name was allocated twice: * ''Nassa'' Röding, 1798 for mainly muricid species with the type species : ''Nassa picta'' Röding, 1798 (= ''Nassa serta'' (Bruguière, 1798). * ''Nassa'' Lamarck, 1799 : established for the species ''Buccinum mutabile'' Linnaeus, 1758, which is now classified as a synonym of ''Nassarius'' Duméril, 1805 in the family Nassariidae. In the 19th and much of the 20th century, all species that were added to the genus ''Nassa'' were Nassa mud snails belonging to the family Nassariidae. After the rediscovery of Röding's catalogue of his collection ''Museum Boltenianum sive catalogus cimeliorum e tribus regnis naturæ quæ olim collegerat Joa. Fried Bolten, M. D. p. d. per XL. annos proto physicus Hamburgensis. Pars secunda continens con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
