Acondicionamiento acústico de un auditorio existente en Valencia
Este informe presenta el estudio del acondicionamiento acústico de un Auditorio existente en un edificio docente (conservatorio de música) en Valencia, proyecto elaborado por Laura Tarrazona Gasque.
A grandes rasgos, se pueden diferenciar en el edificio dos grandes zonas por sus caracterÃsticas y usos. Por una parte el Auditorio y por otra el Conservatorio integrado todo en un edificio en alturas.
En este proyecto será objeto de estudio el Auditorio, sin tener en cuenta el resto de edificio.Tarrazona Gasque, L. (2011). Acondicionamiento acústico de un auditorio existente en Valencia. http://hdl.handle.net/10251/14251.Archivo delegad
Single-cell longitudinal analysis of SARS-CoV-2 infection in human airway epithelium identifies target cells, alterations in gene expression, and cell state changes.
There are currently limited Food and Drug Administration (FDA)-approved drugs and vaccines for the treatment or prevention of Coronavirus Disease 2019 (COVID-19). Enhanced understanding of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and pathogenesis is critical for the development of therapeutics. To provide insight into viral replication, cell tropism, and host-viral interactions of SARS-CoV-2, we performed single-cell (sc) RNA sequencing (RNA-seq) of experimentally infected human bronchial epithelial cells (HBECs) in air-liquid interface (ALI) cultures over a time course. This revealed novel polyadenylated viral transcripts and highlighted ciliated cells as a major target at the onset of infection, which we confirmed by electron and immunofluorescence microscopy. Over the course of infection, the cell tropism of SARS-CoV-2 expands to other epithelial cell types including basal and club cells. Infection induces cell-intrinsic expression of type I and type III interferons (IFNs) and interleukin (IL)-6 but not IL-1. This results in expression of interferon-stimulated genes (ISGs) in both infected and bystander cells. This provides a detailed characterization of genes, cell types, and cell state changes associated with SARS-CoV-2 infection in the human airway
Single-cell multi-omics reveals dyssynchrony of the innate and adaptive immune system in progressive COVID-19.
Dysregulated immune responses against the SARS-CoV-2 virus are instrumental in severe COVID-19. However, the immune signatures associated with immunopathology are poorly understood. Here we use multi-omics single-cell analysis to probe the dynamic immune responses in hospitalized patients with stable or progressive course of COVID-19, explore V(D)J repertoires, and assess the cellular effects of tocilizumab. Coordinated profiling of gene expression and cell lineage protein markers shows that S100
The role of the complement system in traumatic brain injury: a review
Traumatic brain injury (TBI) is an important cause of disability and mortality in the western world. While the initial injury sustained results in damage, it is the subsequent secondary cascade that is thought to be the significant determinant of subsequent outcomes. The changes associated with the secondary injury do not become irreversible until some time after the start of the cascade. This may present a window of opportunity for therapeutic interventions aiming to improve outcomes subsequent to TBI. A prominent contributor to the secondary injury is a multifaceted inflammatory reaction. The complement system plays a notable role in this inflammatory reaction; however, it has often been overlooked in the context of TBI secondary injury. The complement system has homeostatic functions in the uninjured central nervous system (CNS), playing a part in neurodevelopment as well as having protective functions in the fully developed CNS, including protection from infection and inflammation. In the context of CNS injury, it can have a number of deleterious effects, evidence for which primarily comes not only from animal models but also, to a lesser extent, from human post-mortem studies. In stark contrast to this, complement may also promote neurogenesis and plasticity subsequent to CNS injury. This review aims to explore the role of the complement system in TBI secondary injury, by examining evidence from both clinical and animal studies. We examine whether specific complement activation pathways play more prominent roles in TBI than others. We also explore the potential role of complement in post-TBI neuroprotection and CNS repair/regeneration. Finally, we highlight the therapeutic potential of targeting the complement system in the context of TBI and point out certain areas on which future research is needed
Diaqua(nitrato-κ2O,O′)bis(l-valine-κO)lead(II) nitrate at 296 K
The structure of the title complex, [Pb(NO3)(C5H11NO2)2(H2O)2]NO3, had been determined previously at 173 and 193 K, and is now reported at 296 K, in the same space group. The main difference with the low-temperature structures is that a methyl group of one valine ligand is clearly disordered over two positions, for which the occupancies converged to 0.56 (3) and 0.44 (3). Bond-length variations within the coordination sphere of PbII as a function of T are difficult to assess because uncertainties on these parameters are high. On the other hand, Pb...O distances above 2.9 Å cannot be assigned unambiguously to formal Pb—O bonds. As a consequence, the polymeric nature of the complex previously described at 173 K is uncertain, as well as the actual coordination number of PbII, and it is thus not possible to determine if the metal environment is holo- or hemidirected
Aquatris[1-(2,4-dioxo-2H-1-benzopyran-3-ylidene)ethan-1-olato]ethanolgadolinium(III) ethanol monosolvate
The title compound, [Gd(C11H7O4)3(C2H5OH)(H2O)]·C2H5OH, was crystallized from ethanol, affording a solvate. The main ligand in the complex results from deprotonation of the hydroxy group in 3-acetyl-4-hydroxycoumarin (C11H8O4) and the resulting anionic ligands chelate the GdIII centre. Three anions, one ethanol and one water molecule are bonded to the lanthanide, giving an eight-coordinate metal centre with a slightly distorted trigonal–prismatic square-face-bicapped coordination geometry. All water and ethanol molecules participate in an intricate three-dimensional framework of hydrogen bonds. The complex is isostructural to the Tb and Dy compounds reported previously [Guzmán-Méndez et al. (2018). Inorg. Chem. 57, 908–911]
