Anilato-based multifunctional molecular materials
2018
En esta Tesis presentamos varias series de compuestos moleculares basados en el ligando anilato (anilato = C6O4X22- = 2,5-disustituida-3,6-dihidroxi-1,4-benzoquinona) y diferentes átomos metálicos incluyendo metales de los bloques s, p, d y f. En el capítulo uno presentamos la síntesis y caracterización de nuevas sales precursoras, basadas en el ligando anilato, con fórmula general A3[M(C6O4X2)3]; (MIII = Fe, Cr y Ga; X = Cl, Br and NO2). Hemos usado diferentes cationes A+ (A = K+, [PPh3Et]+, [PPh3Pr]+, [PBu4]+, [NBu4]+, [NHep4]+, [PPh4]+ y K+, compuestos 1-20) para estudiar el papel que juega la forma y el tamaño del catión en la estructura y simetría de las correspondientes sales. Este es…
Integrated CGH/WES Analyses Advance Understanding of Aggressive Neuroblastoma Evolution: A Case Study
2021
Neuroblastoma (NB) is the most common extra-cranial malignancy in preschool children. To portray the genetic landscape of an overly aggressive NB leading to a rapid clinical progression of the disease, tumor DNA collected pre- and post-treatment has been analyzed. Array comparative genomic hybridization (aCGH), whole-exome sequencing (WES), and pharmacogenetics approaches, respectively, have identified relevant copy number alterations (CNAs), single nucleotide variants (SNVs), and polymorphisms (SNPs) that were then combined into an integrated analysis. Spontaneously formed 3D tumoroids obtained from the recurrent mass have also been characterized. The results prove the power of combining C…
Genomic structure and functional characterization of the human ADAM10 promoter
2005
The ADAM10 gene encodes a membrane-bound disintegrin-metalloproteinase, which, after overexpression in an Alzheimer disease (AD) mouse model, prevents amyloid pathology and improves long-term potentiation and memory. Because enhancing ADAM10 expression appears to be a reasonable approach for treatment of AD, we functionally analyzed the ADAM10 gene. Both human and mouse ADAM10 genes comprise approximately 160 kbp, are composed of 16 exons, and are evolutionarily highly conserved within 500 bp upstream of either translation initiation site. By using luciferase reporter assays, we demonstrate that nucleotides -2179 to -1 upstream of the human ADAM10 translation initiation site represent a fun…

Synthesis, Thermal, and Optical Properties of Tris(5‐aryl‐1,3,4‐oxadiazol‐2‐yl)‐1,3,5‐triazines, New Star‐Shaped Fluorescent Discotic Liquid Crystals
2019
Abstract The synthesis of tris(aryloxadiazolyl)triazines (TOTs), C 3‐symmetrical star‐shaped mesogenes with a 1,3,5‐triazine center, 5‐phenyl‐1,3,4‐oxadiazole arms, and various peripheral alkoxy side chains is reported. Threefold Huisgen reaction on a central triazine tricarboxylic acid and suitable aryltetrazoles yields the title compounds. Selected analogues with a benzene center are included in this study and allow for an evaluation of the impact of the central unit on the physical properties. Thermal (differential scanning calorimetry, DSC; polarization optical microscopy, POM), optical (UV/Vis, fluorescence), electric (time of flight, TOF), and structural (single crystal; wide‐angle X‐…

STABILITY OF A STOCHASTICALLY PERTURBED MODEL OF INTRACELLULAR SINGLE-STRANDED RNA VIRUS REPLICATION
2019
Compared to the replication of double-stranded RNA and DNA viruses, the replication of single-stranded viruses requires the production of a number of intermediate strands that serve as templates for the synthesis of genomic-sense strands. Two theoretical extreme mechanisms for replication for such single-stranded viruses have been proposed; one extreme being represented by the so-called linear stamping machine and the opposite extreme by the exponential growth. Of course, real systems are more complex and examples have been described in which a combination of such extreme mechanisms can also occur: a fraction of the produced progeny resulting from a stamping-machine type of replication that…
Solid-state mechanochemical synthesis of multinary metal halide semiconductors for optoelectronics: From powder to thin film
2020
En la última década, las perovskitas de haluro de plomo, así como otros haluros de metales múltiples, incluidas las alternativas sin plomo, han demostrado ser materiales prometedores para su uso en optoelectrónica. Por lo tanto, se buscan activamente nuevas formas de producir semiconductores de alta pureza a gran escala. Por tanto, el objetivo principal de esta tesis doctoral es el desarrollo de perovskitas y semiconductores relacionados utilizando métodos sin disolventes. Además, con la perspectiva del uso de dichos materiales en optoelectrónica a escala industrial, el foco está puesto en trabajar con materiales benignos para el desarrollo de alternativas a las perovskitas tóxicas. La sínt…
Search for a Dark Leptophilic Scalar in e(+) e(-) Collisions
2020
Many scenarios of physics beyond the standard model predict the existence of new gauge singlets, which might be substantially lighter than the weak scale. The experimental constraints on additional scalars with masses in the MeV to GeV range could be significantly weakened if they interact predominantly with leptons rather than quarks. At an e+e- collider, such a leptophilic scalar (φL) would be produced predominantly through radiation from a τ lepton. We report herein a search for e+e-→τ+τ-φL, φL→ℓ+ℓ- (ℓ=e, μ) using data collected by the BABAR experiment at SLAC. No significant signal is observed, and we set limits on the φL coupling to leptons in the range 0.04<mφL<7.0 GeV. These bounds s…
