La carta

Este documental narra la fuga de tres presos ocurrida, en 2003, en la localidad de Tres Lomas, un pequeño pueblo ubicado al oeste de la provincia de Buenos Aires donde prevalece la tranquilidad y prácticamente se conocen entre todos. El hecho es relatado por distintos protagonistas del pueblo, entre ellos, policías implicados, periodistas locales, y vecinos. Estos testimonios, junto a escenas ficcionadas y registros documentales del pueblo y lugares claves para esta historia; reflejan cómo se vivó este suceso y de qué manera corrompió la vida rutinaria y tranquila de la comunidad.Facultad de Arte

Nanoparticles and potential neurotoxicity: focus on molecular mechanisms

The last decades have seen an explosive increase in the development of nanoparticles and in their use in consumer, industrial and medical applications. Their fast diffusion has also raised widespread concern about the potential toxic effects on living organisms, including humans: at the nanoscale, they can interact with subcellular components such as membranes, proteins, lipids, nucleic acids, thus inducing unpredicted functional perturbations in cells and tissues. The nervous tissue is a particular sensitive target, because its cellular components (mainly neurons and glial cells) are tightly regulated and metabolically exigent biological entities. While the literature on the potential toxicity of nanoparticles has grown in parallel with their utilization, the available data on neurotoxicity are less abundant. In particular, information on the neuronal molecular targets of nanoparticles is still largely incomplete. A better understanding of this issue is highly relevant for the rational and controlled design of nanoparticles, both for their general utilization and more specifically for their use in the promising field of nanoneuromedicine. In this review, we will discuss the available information on the mechanisms involved in the interaction between nanoobjects and cells of the nervous system, focusing on the known molecular actors, both at the plasma membrane and in intracellular compartments

Foraminíferos y sedimentos de playa blanca, isla gorgona

Se estudió la microfauna de foraminíferos y los sedimentos de Playa Blanca, isla Gorgona. Se identificó un conjunto bentónico característico de zona litoral, sin la presencia de especies propias de ambiente arrecifal. Lapobreza de la población es la principal característica y se justifica por la amplitud de las mareas y la acidez de las aguas. La composición mineralógica del sedimentodemuestra su procedencia de las rocas que forman la isla.Foraminiferal microfauna and the sediment of Playa Blanca, Gorgona Island, were studied. A group of characteristic foraminifera on the litoral zone were identified, with the absence of the typical species of the coral reef environment. The scarcity of the population is the main characteristic and it is "supported" by the amplitude of the tides and the water "acidity".  The mineralogical composition of the sediment shows its provenance from the rocks of the island
