It will be sought to understand the importance of Jesus' resurrection in Paul's conversion and, at the same time, to understand how the resurrection of Jesus is at the center of Paul's preaching, his faith, his vision, and how he struck the New Testament Church to substantiate these questions, we go through a bibliographical analysis of the theories of biblical theologians and some theologians of systematic theology. / Esta disserta??o reflete sobre o tema: ?E Apareceu tamb?m a mim?: A vis?o de Paulo sobre a ressurrei??o, ap?s o encontro com Jesus no caminho de Damasco. Buscar-se-? compreender a import?ncia da ressurrei??o de Jesus na convers?o de Paulo, e, concomitantemente entender como a ressurrei??o de Jesus est? no centro da prega??o de Paulo, a sua f?, a sua vis?o e como atingiu a Igreja do Novo Testamento para fundamentar essas quest?es, percorremos atrav?s de uma an?lise bibliogr?fica o pensamento de te?logos da ?rea b?blica e alguns te?logos da teologia sistem?tica.

Background: Syllids are a species rich annelid family possessing remarkable regenerative ability, which is not only the response after traumatic injury, but also a key step during the life cycle of several syllid taxa. In these animals the posterior part of the body becomes an epitoke and is later detached as a distinct unit named stolon. Such a sexual reproductive mode is named schizogamy or stolonization. The prostomium and the proventricle, a modified foregut structure, have been proposed to have a control function during this process, though the concrete mechanisms behind it have never been elucidated. Results: By using different experimental set-ups, histology and immunohistochemistry combined with subsequent cLSM analyzes, we investigate and document the regeneration and stolonization in specimens of Typosyllis antoni that were amputated at different levels throughout the antero-posterior body axis. The removal of the anterior end including the proventricle implies an incomplete anterior regeneration as well as severe deviations from the usual reproductive pattern, i.e. accelerated stolonization, masculinization and the occurrence of aberrant stolons. The detailed anatomy of aberrant stolons is described. A histological study of the proventricle revealed no signs of glandular or secretory structures. The ventricle and the caeca are composed of glandular tissue but they are not involved in the reproductive and regenerative processes. Conclusions: As in other investigated syllids, the proventricle region has a significant role during stolonization and reproduction processes in Typosyllis antoni. When the proventricle region is absent, anterior and posterior regeneration are considerably deviated from the general patterns. However, proventricle ultrastructure does not show any glandular component, thereby questioning a direct involvement of this organ itself in the control of reproduction and regeneration. Our findings offer a comprehensive starting point for further studies of regeneration and reproductive control in syllids as well as annelids in general.
