Las criadas de Penélope. Escribir la violencia
2007
Partiendo de las reflexiones sobre la violencia de Walter Benjamin, Simone Weil y Hannah Arendt, en este artículo se analiza la reescritura que realizan Wislawa Szymborska, Sophia de Mello, Claribel Alegría, Margaret Atwood y María Zambrano de una serie de figuras míticas que sufrieron la violencia: la mujer de Lot, Eurídice, las criadas de Penélope y Antígona.
Mitos, significados y usos políticos: Hernán Cortés y Bartolomé de Las Casas en la crisis del Antiguo Régimen
2017
Las figuras históricas de Hernán Cortés y Bartolomé de Las Casas han adquirido diferentes valoraciones y significados a lo largo del tiempo. Historiarlos en el contexto de la crisis del Antiguo Régimen es uno de los principales objetivos que se ha pretendido alcanzar en esta tesis doctoral. Alrededor de ambos personajes se han construido diversas corrientes de opinión que han dado lugar a una compleja mitología histórica, teñida con el negro y el dorado de la Leyenda, aún vigente en nuestros días. En un momento histórico de debate intelectual sobre el mundo americano, de crisis colonial y críticas contra la monarquía española, atenderemos a dos de las representaciones que adquirieron especi…
Conocimiento pedagógico del contenido para la enseñanza del tema mitosis: un estudio de casos con docentes universitarios de Argentina
2015
The pedagogical content knowledge (PCK) for teaching mitosis at university isan unexplored field. We report the characterization of university teachers’ PCK on mitosisemploying the Content Representation questionnaire (CoRe) and Professional and Pedagogicalexperience Repertoire (PaP-eR). The differences found in the teachers’ CDC are consistent withthe characteristics of this construct: it is specific to a topic, a teacher and a context. The PCKdevelopment of university teachers in the context of teaching centered on the transmissionof knowledge emerges as a possible strategy to reorient the teaching of mitosis to approachesbased on the construction of scaffoldings that facilitate student l…
PML nuclear body-residing proteins sequentially associate with HPV genome after infectious nuclear delivery.
2019
Subnuclear promyelocytic leukemia (PML) nuclear bodies (NBs) are targeted by many DNA viruses after nuclear delivery. PML protein is essential for formation of PML NBs. Sp100 and Small Ubiquitin-Like Modifier (SUMO) are also permanently residing within PML NBs. Often, large DNA viruses disassemble and reorganize PML NBs to counteract their intrinsic antiviral activity and support establishment of infection. However, human papillomavirus (HPV) requires PML protein to retain incoming viral DNA in the nucleus for subsequent efficient transcription. In contrast, Sp100 was identified as a restriction factor for HPV. These findings suggested that PML NBs are important regulators of early stages o…

La representación de la historia reciente en la ficción televisiva española actual
2017
Based upon the assumption that television has a strong impact in the vision that we have about the pass, along the next pages we analyse the recent history representations present in Spain's tv-fiction and cinematographic productions too. As we establish relationships between both audiovisual productions, we propose to investigate about the construction of Transition's mythos and analyse if there is a television model in the mode of representing the recent history.
Prediction model for aneuploidy in early human embryo development revealed by single-cell analysis.
2014
Aneuploidies are prevalent in the human embryo and impair proper development, leading to cell cycle arrest. Recent advances in imaging and molecular and genetic analyses are postulated as promising strategies to unveil the mechanisms involved in aneuploidy generation. Here we combine time-lapse, complete chromosomal assessment and single-cell RT–qPCR to simultaneously obtain information from all cells that compose a human embryo until the approximately eight-cell stage (n=85). Our data indicate that the chromosomal status of aneuploid embryos (n=26), including those that are mosaic (n=3), correlates with significant differences in the duration of the first mitotic phase when compared with e…
The pattern of neuroblast formation, mitotic domains and proneural gene expression during early brain development in Drosophila.
2003
In the Drosophila embryo, studies on CNS development have so far mainly focused on the relatively simply structured ventral nerve cord. In the trunk, proneural genes become expressed in small cell clusters at specific positions of the ventral neuroectoderm. A lateral inhibition process mediated by the neurogenic genes ensures that only one cell within each proneural cluster delaminates as a neural stem cell (neuroblast). Thus, a fixed number of neuroblasts is formed, according to a stereotypical spatiotemporal and segmentally repeated pattern, each subsequently generating a specific cell lineage. Owing to higher complexity and hidden segmental organisation, the mechanisms underlying the dev…
Long-term response of osteogenic cells on micron and submicron-scale-structured hydrophilic titanium surfaces: sequence of cell proliferation and cel…
2010
Objective: Modifications of surface topography and surface chemistry are key factors for guiding target cells during dental implant healing. Recent in vitro studies confirmed promotion of early osteogenic cell differentiation on submicron scaled surfaces in particular when hydrophilized. However, no long-term observations on both osteogenic cell proliferation as well as on cell maturation have been reported for respectively modified surfaces. Aim of this study was to monitor osteogenic cell proliferation and expression of specific osteogenic cell differentiation markers on a protein level over an extended period of 3 weeks with respect to surface modifications. Material and methods: Modifie…
Organometallic complexes with biological molecules: V.In vivo cytotoxicity of diorganotin(IV)-amoxicillin derivatives in mitotic chromosomes ofrutilu…
1995
In order to test in vivo cytotoxicity of diorganotin(IV)-amoxicillin (amox) derivatives, mitotic chromosomes of Rutilus rubilio (Pisces, Cyprinidae) have been analyzed using two different chromosome-staining techniques. Results gathered after exposure of fish to the free amox.3H 2 O, R 2 SnClamox.2H 2 O, and R 2 Snamox 2 .2H 2 O (R = methyl, butyl and phenyl ; amox - = 6-[D(-)-β-amino-p-hydroxyphenylacetamido]penicillinate) suggest that methyl derivatives seem to exert a lower cytotoxicity than butyl and phenyl ones and that R 2 Snamox 2 .2H 2 O derivatives are more toxic than R 2 Snclamox.2H 2 O at both 10 -5 and 10 -7 mol dm -3 concentrations. The following structural lesions have been id…
