The playa environments of the Lodève Permian basin (Languedoc-France).
2008
28 pages; International audience; The Lodève Permian synrift sequence is represented by thick stacked climate-controled playa cycles which have been constrained by structural, sedimentological, geochemical and paleontological processes. The present paper merges the different results in order to better constrain the dynamics and palaeoecologycal evolution of the playa system from Late Cisuralian to Early Lopingian time. In this depositional environment, thining upwards sheet-flood sequences represent flooding events; they are relayed by ephemeral ponding, suspension settling and limited carbonate precipitation accompanied by large amounts of shallow to subaerial sedimentary structures (curre…
Aplicación de la clasificación de San Diego en el estudio médico-legal de la Muerte Súbita del Lactante
2020
INTRODUCCIÓN La Muerte Súbita del Lactante (MSL) representa un problema universal y grave. El Síndrome de Muerte Súbita del Lactante (SMSL) es la primera causa de muerte en lactantes durante el primer año de vida en países desarrollados y se define como la muerte súbita e inesperada de un lactante, que ocurre durante el sueño y permanece inexplicada tras la realización de una completa investigación postmortem (autopsia con análisis complementarios, examen del lugar de la muerte y revisión de la historia clínica). De esta definición se desprende la clasificación de San Diego basada en las categorías IA, IB y II. Tiene una patogénesis compleja y heterogénea, siendo la teoría del triple riesgo…
Infection-induced chromatin modifications facilitate translocation of herpes simplex virus capsids to the inner nuclear membrane
2021
Herpes simplex virus capsids are assembled and packaged in the nucleus and move by diffusion through the nucleoplasm to the nuclear envelope for egress. Analyzing their motion provides conclusions not only on capsid transport but also on the properties of the nuclear environment during infection. We utilized live-cell imaging and single-particle tracking to characterize capsid motion relative to the host chromatin. The data indicate that as the chromatin was marginalized toward the nuclear envelope it presented a restrictive barrier to the capsids. However, later in infection this barrier became more permissive and the probability of capsids to enter the chromatin increased. Thus, although …
