Roman d'apprentissage et liberté romanesque

RésuméA l'image de son personnage, qui se déplace en subissant toutes sortes d'expériences lui permettant de « grandir », le roman d'apprentissage traverse les siècles et les cultures en Occident, mais trouve aussi un écho tout à fait particulier parmi de nombreux romans d'Afrique noire francophone. Ce genre littéraire se découvre tant parmi les productions de l'époque coloniale que parmi les plus contemporaines et peut être envisagé en tant que métaphore d'une autonomie langagière et littéraire progressivement acquise, tout en gardant à l'esprit que les catégories génériques occidentales n'ont pas à être dupliquées telles quelles sur les productions fictionnelles africaines. L'hypothèse de travail associe les dimensions diachronique et synchronique pour observer un croisement de pratiques formelles et génériques dans les textes de fiction romanesque d'Afrique subsaharienne. Elle utilise dans ce cadre les romans Karim d'Ousmane Socé (1935) et Une Vie de boy de Ferdinand Oyono (1956).AbstractLike their protagonists, who undergo a journey and in the process come of age, coming-on-age novels have abounded and evolved throughout the centuries in the West - but they are also present in sub-Saharian African literature. The coming-of-age genre was popular during colonial times and is even more so today. Where African Francophone literature is concerned, we can take this type of novel as a metaphor for its gradually acquired linguistic and literary autonomy, keeping in mind that Western genres and patterns cannot be applied willy-nilly to this new generation of African litterateurs. Taking into account both historical and territorial aspects, we will examine African Francophone literature, stylistically and thematically, in its approch to gender. To do so, we will analyse Ousmane Socé's Karim (1935) and Ferdinand Oyono's Une vie de boy (A boy servant's life, 1956).

Induction of apoptosis by mercury compounds depends on maturation and is not associated with microglial activation

The earliest sign of neurotoxicity observed after exposure of three-dimensional brain cell cultures to low concentrations of mercury compounds is a microglial reaction. We hypothesized that an induction of apoptosis by mercury compounds could be an activating signal of the microglial reaction. Aggregating brain cell cultures of fetal rat telencephalon were treated for 10 days with either mercury chloride or monomethylmercury chloride at noncytotoxic concentrations during two developmental periods: from day 5 to 15, corresponding to an immature stage, and from day 25 to 35 corresponding to a mature stage. Apoptosis was evaluated by the TUNEL technique. It was found that both mercury compounds caused a significant increase in the number of apoptotic cells, but exclusively in immature cultures exhibiting also spontaneous apoptosis. Double staining by the TUNEL technique combined with either neuronal or astroglial markers revealed that the proportion of cells undergoing apoptosis was highest for astrocytes. Furthermore neither an association nor a colocalization was found between apoptotic cells and microglial cells. In conclusion, it appears that the induction of apoptosis by mercury compounds in immature cells is only an acceleration of a spontaneously occurring process, and that it is not a directly related to the early microglial reaction.

Teresa San Roman, antropologa

Después publicar de la entrevista a Ramón Valdés (v. Perifèria 5), continúa la colaboración de la revista con el Proyecto Entrevistas3. En esta ocasión los alumnos han entrevistado a la Catedrática de la UAB, Teresa San Román Espinosa. La entrevista tuvo lugar el pasado 25 de junio de 2007 en su despacho del departamento, en un ambiente muy cercano y distendido, dando como resultado un extenso pero a su vez ameno repaso por el recorrido vital e intelectual de una figura de referencia imprescindible en la antropología social española, reconocida y admirada por su trabajo de investigación con los gitanos y por su compromiso personal y profesional con una antropología aplicada e implicada.
