Constructing Memory through Television in Argentina

La televisión representa el pasado reciente de la Argentina a través de vínculos específicos con la memoria social: como un “emprendedor de la memoria” definiendo las agendas públicas, como un vehículo de transmisión intergeneracional sobre el pasado y como un creador de significados por medio de imágenes, sonidos y palabras, esto es, un “escenario para la memoria”. Un análisis de los vínculos entre televisión y memorias, construido alrededor de la desaparición forzada de personas durante la dictadura militar de 1976 a 1983, revela la manera compleja en la cual los obstáculos para relatar ese periodo trágico se combinan con el intento de vender un producto y entretener al espectador.Television represents Argentina’s recent past through three specific links with social memory: as an “entrepreneur of memory,” shaping public agendas, as a vehicle of intergenerational transmission of past events, and as a creator of meaning through images, sounds, and words, a “stage for memory”. An analysis in terms of the links between television and the memories constructed around the forced disappearance of persons during the 1976–1983 military dictatorship reveals the complex way in which the obstacles when narrating an extreme experience are combined with the attempt to sell a product and entertain the spectator.Fil: Feld, Claudia Viviana.

Pedagogía y entretención en la industria cultural italiana

La nueva mirada a la historia de los medios ha penetrado hasta las raíces de aquellas disciplinas que parecían haberla excluido. Éstas, por el contrario, le han ofrecido un fértil terreno de cultivo. Partiendo de esta premisa, Fausto Colombo aborda el panorama evolutivo de la industria cultural italiana y muestra una contraposición entre dos estrategias divergentes que por largo tiempo se han justificado recíprocamente, la educativa y la del entretenimiento. Ambas son constantes recurrentes y, en períodos determinados, se puede asistir al predominio de una o de la otra

Cream Formulation Impact on Topical Administration of Engineered Colloidal Nanoparticles

In order to minimize the impact of systemic toxicity of drugs in the treatment of local acute and chronic inflammatory reactions, the achievement of reliable and efficient delivery of therapeutics in/through the skin is highly recommended. While the use of nanoparticles is now an established practice for drug intravenous targeted delivery, their transdermal penetration is still poorly understood and this important administration route remains almost unexplored. In the present study, we have synthesized magnetic (iron oxide) nanoparticles (MNP) coated with an amphiphilic polymer, developed a water-in-oil emulsion formulation for their topical administration and compared the skin penetration routes with the same nanoparticles deposited as a colloidal suspension. Transmission and scanning electron microscopies provided ultrastructural evidence that the amphiphilic nanoparticles (PMNP) cream formulation allowed the efficient penetration through all the skin layers with a controllable kinetics compared to suspension formulation. In addition to the preferential follicular pathway, also the intracellular and intercellular routes were involved. PMNP that crossed all skin layers were quantified by inductively coupled plasma mass spectrometry. The obtained data suggests that combining PMNP amphiphilic character with cream formulation improves the intradermal penetration of nanoparticles. While PMNP administration in living mice via aqueous suspension resulted in preferential nanoparticle capture by phagocytes and migration to draining lymph nodes, cream formulation favored uptake by all the analyzed dermis cell types, including hematopoietic and non-hematopoietic. Unlike aqueous suspension, cream formulation also favored the maintenance of nanoparticles in the dermal architecture avoiding their dispersion and migration to draining lymph nodes via afferent lymphatics
