Hispania en la obra geográfica de Agripa

2015

Marco Vipsanio Agripa (64/63-12 a.C.) estuvo en Hispania en 19 a.C. para dirigir la campaña que culminó la conquista romana de la península durante el principado de Augusto. Han quedado diversas menciones a la obra geográfica que, bajo sus auspicios, recogió distancias y medidas de todo el mundo conocido en su época, valiéndose de la enorme cantidad de recursos humanos y materiales que la administración romana estaba en disposición de poner a su alcance.

Geografía literaria y límites provinciales: la península Ibérica entre Eratóstenes y Agripa

2013

Desarrollamos aquí una revisión de la concepción geográfica de la península Ibérica, centrando el estudio de manera prioritaria en los fundamentos numéricos transmitidos por las principales fuentes geográficas del mundo antiguo. En esta panorámica, se evidencia la esencial importancia de las obras cartográficas de Eratóstenes y Agripa. La primera tendrá un influjo decisivo para el surgimiento de la literatura de contenido geográfico desarrollada por Polibio, Artemidoro y Posidonio, y servirá de sustento a la cartografía de Ptolomeo, que reproduce en sus líneas esenciales los resultados de Eratóstenes, pero filtrados a través de la intermediación crítica de Hiparco. La obra cartográfica de A…

De Montaigne a Lope: distintos resultados de una misma decisión

2009

This essay presents the initial hypothesis of the diversity of cases shown by Lope de Vega’s theatre, that multiply perspectives and different endings from the same basic types of conflicts and designs, and tries to verify them with contemporary thought. This diversity is related with a certain type of discourse that has begun to spread out in the very beginning of the Renaissance and was gradually displacing the pre-eminence of universal principles (neo-platonic, or neoaristotelic and scholastic) for an invitation to casuistic analysis, an ethical modality applied that chose the concrete analysis of the concrete situation in front of the universally required dogmas. A type of discourse tha…

Quantitative characterization of tetraspanin 8 homointeractions in the plasma membrane

2021

The spatial distribution of proteins in cell membranes is crucial for signal transduction, cell communication and membrane trafficking. Members of the Tetraspanin family organize functional protein clusters within the plasma membrane into so-called Tetraspanin-enriched microdomains (TEMs). Direct interactions between Tetraspanins are believed to be important for this organization. However, studies thus far have utilized mainly co-immunoprecipitation methods that cannot distinguish between direct and indirect, through common partners, interactions. Here we study Tetraspanin 8 homointeractions in living cells via quantitative fluorescence microscopy. We demonstrate that Tetraspanin 8 exists i…

A Golgi study of the principal projection neurons of the medial cortex of the lizardPodarcis hispanica

1997

The medial cortex of lizards is a simple three-layered brain region displaying many characteristics that parallel the hippocampal fascia dentata of mammals. Its principal neurons form a morphologically diverse population, partly as a result of the prominent continuous growth of this nervous center. By using the classic Golgi impregnation method, we describe here the morphology of the principal neurons populating the medial cortex of Podarcis hispanica. These were projection neurons giving off descending axons. These axons displayed deep collateral branches provided with prominent axonal boutons, while the main axonal branch reached adjacent cortical areas and the bilateral septum. According…

Regulation of IgG antibody responses by epitope density and CD21-mediated costimulation

2002

Epitope density and organization have been shown to be important factors for B cell activation in many animal model systems. However, it has been difficult to separate the role of antigen organization from the role of local antigen concentrations because highly organized antigens are usually particulate whereas non-organized antigens are more soluble. Hence, highly organized and non-organized antigens may interact with different cell types and in different locations within lymphoid organs. In order to assess the role of antigen organization in regulating B cell responses, we immunized mice with highly repetitive virus-like particles, which exhibit different epitope densities covalently atta…
