13. A fauna dos bancos de areia de phragmatopoma lapidosa Kinberg, 1867, (Annelidae-Polychaeta), da região de Ubatuba, SP
Sabellariideos têm sido notados por sua habilidade em formar arrecifes ou aglomerados de tubos. Utilizando partículas de areia cimentadas com muco proteínas, constroem estruturas compactas as quais abrigam considerável fauna associada. No Brasil os estudos sobre esta família restringem-se a pequenas notas e observações preliminares. Constatada a impor

14. A endofauna de schizoporella unicornis (Johnston, 1847) (Bryozoa), no litoral norte do Estado de São Paulo
Os briozoários têm sido considerados pouco interessantes em termos de fauna associada. Para que se pudesse demonstrar sua importância dentre os animais sésseis que, reconhecidamente, se constituem em abrigo ou substrato para diversos organismos, propôs-se estudar a endofauna de Schisoporella unicornis. Tentou-se também esclarecer os fatores que determi

15. Inducible morphology, heterochrony, and size hierarchies in a colonial invertebrate monoculture.
Conditional or inducible strategies are a powerful tool for analyzing the evolution of aggressive behavior. Structures such as stolons and nematocyst-laden tentacles, induced to deter encroachment by competitors, are proportionately better represented in clonal and colonial marine invertebrates than in aclonal animals. Stolons can be produced by colonies of

16. Distinct modulatory effects of bryostatin 1 and staurosporine on the biosynthesis and expression of the HIV receptor protein (CD4) by T cells.
A family of structurally related macrocyclic lactones, bryostatins, have recently been shown to display several intriguing pharmacologic properties. Bryostatins are biosynthetic products of bryozoa phyllum of marine animals. To extend the analyses of the biological activities of these highly unusual biosynthetic animal products, we have examined the effect o

17. The design, computer modeling, solution structure, and biological evaluation of synthetic analogs of bryostatin 1
The bryostatins are a unique family of emerging cancer chemotherapeutic candidates isolated from marine bryozoa. Although the biochemical basis for their therapeutic activity is not known, these macrolactones exhibit high affinities for protein kinase C (PKC) isozymes, compete for the phorbol ester binding site on PKC, and stimulate kinase activity in vitro
