By tha way, regarding recent publication on Amphinomidae we just posted in
our lab page another one on a new deep sea Paramphinome, and regarding Rocas
Atoll, there is one on Sabellids from the same place.  All of them are in
the page: http://www.biologia.ufrj.br/labs/labpoly/publications.html

Yours,

> Abstract: "The marine fireworm, Eurythoe complanata, is known as a
> dangerous animal for humans because it induces skin inflammation through its
> small setae. Here, the inflammation-inducing substance was successfully
> isolated from the whole body using a methanolic extraction, and the
> inflammatory activity was determined using a bioassay. The structure was
> spectroscopically revealed to be a trimethylammonium with an unsaturated
> carbon chain and was named complanine. Complanine enhanced PKC activity in
> combination with TPA in vitro. This may explain the molecular mechanism
> behind its inflammation-inducing activity.
