"Las manos de mama" di Nellie Campobello: madre reale e madre mitica
2018
In "Las manos de mama" by the Mexican writer Nellie Campobello the figure of the mother is idealized and associated with nature, she is mother-nature who reminds the vision that AZtec civilitazion shared about Teteoinnan, the mother goddess, queen of the earth.

Stick around: Cell–Cell Adhesion Molecules during Neocortical Development
2021
The neocortex is an exquisitely organized structure achieved through complex cellular processes from the generation of neural cells to their integration into cortical circuits after complex migration processes. During this long journey, neural cells need to establish and release adhesive interactions through cell surface receptors known as cell adhesion molecules (CAMs). Several types of CAMs have been described regulating different aspects of neurodevelopment. Whereas some of them mediate interactions with the extracellular matrix, others allow contact with additional cells. In this review, we will focus on the role of two important families of cell–cell adhesion molecules (C-CAMs), classi…
Adaptación y resistencia al orden social neoliberal en Chile : habitus y discursos sociales El caso de la Región de Antofagasta.
2013
La transición política chilena (1990-2010) presenta rasgos propios que la convierten en un caso de estudio de interés al menos por dos motivos. En primer lugar, porque tanto la recuperación de la democracia como la desinstalación del modelo socioeconómico neoliberal están siendo más lentas y problemáticas que en el resto del cono sur, y, en segundo lugar, porque la dictadura militar y/o el modelo neoliberal han transformado profundamente la subjetividad política del pueblo chileno, que hasta ahora parece mayoritariamente adaptado, ya sea por resignación o convencimiento, al nuevo orden social. La aparente singularidad del caso Chileno en el ámbito suramericano lleva a preguntarnos por las c…
Enkephalin-containing interneurons are specialized to innervate other interneurons in the hippocampal CA1 region of the rat and guinea-pig
1998
Enkephalins are known to have a profound effect on hippocampal inhibition, but the possible endogenous source of these neuropeptides, and their relationship to inhibitory interneurons is still to be identified. In the present study we analysed the morphological characteristics of met-enkephalin-immunoreactive cells in the CA1 region of the rat and guinea-pig hippocampus, their coexistence with other neuronal markers and their target selectivity at the light and electron microscopic levels. Several interneurons in all subfields of the hippocampus were found to be immunoreactive for met-enkephalin. In the guinea-pig, fibres arising from immunoreactive interneurons were seen to form a plexus …
Continuous neuronal integration in the cerebral cortex of rodents and humans
2021
La plasticidad neuronal es la capacidad del sistema nervioso para realizar cambios funcionales adaptativos, durante el desarrollo y la edad adulta. Se refiere a todo tipo de cambios que modifican la forma y estructura de las neuronas y de las células gliales del sistema nervioso central (SNC). Entre los diferentes niveles de plasticidad que ocurren en el cerebro adulto, la neurogénesis es un tipo de plasticidad cerebral, que implica la producción e incorporación continua de nuevas neuronas en las redes neuronales funcionales. En el cerebro de los mamíferos adultos, las nuevas neuronas se generan tradicionalmente en dos "nichos neurogénicos canónicos": la zona subventricular (SVZ) y la zona …
The lizard cerebral cortex as a model to study neuronal regeneration
2002
The medial cerebral cortex of lizards, an area homologous to the hippocampal fascia dentata, shows delayed postnatal neurogenesis, i.e., cells in the medial cortex ependyma proliferate and give rise to immature neurons, which migrate to the cell layer. There, recruited neurons differentiate and give rise to zinc containing axons directed to the rest of cortical areas, thus resulting in a continuous growth of the medial cortex and its zinc-enriched axonal projection. This happens along the lizard life span, even in adult lizards, thus allowing one of their most important characteristics: neuronal regeneration. Experiments in our laboratory have shown that chemical lesion of the medial cortex…

Renta de emergencia familiar en Gandia
2011
Sensible ante la situación económica y de nuevas necesidades emergentes, el Ayuntamiento de Gandia, como principal promotor de políticas sociales, considera necesario integrar dentro de sus iniciativas para promover la igualdad, la solidaridad y la mejora de la calidad de vida, un recurso económico para paliar las distintas situaciones en las que se encuentran familias sin ingresos debido a que los adultos integrantes de la unidad familiar se encuentran en situación de desempleo. Se impulsa, como respuesta a estas nuevas necesidades, una prestación de carácter periódico denominada Renta de Emergencia Familiar (REF) que viene acompañada de un conjunto de actuaciones de carácter municipal dir…
Revision of New World Species of the Shore-fly Subgenus Allotrichoma Becker of the Genus Allotrichoma with Description of the Subgenus Neotrichoma (D…
2012
The New World species of the subgenera Allotrichoma Becker and Neotrichoma (new subgenus) are revised, including a phylogenetic analysis of the species groups and subgenera within the genus Allotrichoma. For phylogenetic perspective and to document the monophyly of the genus Allotrichoma and its included subgenera and species groups, we also provide a cladistic analysis of genera within the tribe Hecamedini. The ingroup included seven exemplar congeners from within Allotrichoma. Outgroup sampling included exemplars of other genera within Hecamedini and from the putative sister group, Lipochaetini, and to root the analysis, we used an exemplar of the tribe Discocerinini. Analyses with succes…
