Notropics

OBJECTIVE: Persistent shock (PS) or recurrent shock (RS) after initial fluids and vasoactives can be secondary to myriad complex mechanisms, and these patients can have a high mortality. We developed a noninvasive tiered hemodynamic monitoring approach which included, in addition to basic echocardiography, cardiac output monitoring and advanced Doppler studies to determine the etiology and provide targeted therapy of PS/RS. DESIGN: Prospective observational study...

Rhabdias anolis n. sp. from the lungs of Anolis frenatus collected in Panama is described and illustrated. Rhabdias anolis n. sp. represents the 45th species assigned to the genus and the ninth from the Notropical Realm. It is distinguished from all other Neotropical species by the presence of a pair of sessile lateral papillae on its tail.

Various 1-trans-cinnamoyl-2-pyrrolidinones (6a-k) and 1-[trans-3-(pyridyl)acryloyl]-2-pyrrolidinones (9a-c) were prepared as analogues of the notropic agent, aniracetam (2), and their effects on hemicholinium-induced impairment of water maze learning in mice were examined. 1-(trans-3-Methoxycinnamoyl)-, 1-(trans-4-methoxycinnamoyl)- and 1-(trans-4-chlorocinnamoyl)-2-pyrrolidinones (6c, d, h) and 1-[trans-3-(3-pyridyl)acryloyl]-2-pyrrolidinone (9c) were found to be more active than aniracetam in these tests...
