A Novel Role for CSRP1 in a Lebanese Family with Congenital Cardiac Defects
2017
Despite an obvious role for consanguinity in congenital heart disease (CHD), most studies fail to document a monogenic model of inheritance except for few cases. We hereby describe a first-degree cousins consanguineous Lebanese family with 7 conceived children: 2 died in utero of unknown causes, 3 have CHD, and 4 have polydactyly. The aim of the study is to unveil the genetic variant(s) causing these phenotypes using next generation sequencing (NGS) technology. Targeted exome sequencing identified a heterozygous duplication in CSRP1 which leads to a potential frameshift mutation at position 154 of the protein. This mutation is inherited from the father, and segregates only with the CHD phen…
Uso de Software-Defined Radio en la enseñanza de sistemas de comunicaciones
2017
[ES] En la docencia de sistemas de comunicación hay una componente teórica elevada. La percepción de los estudiantes al estudiar estas asignaturas es negativa. Este trabajo trata de explicar la motivación y la estrategia seguida para reorientar esta percepción a partir de la introducción de elementos de “Software-Defined Radio” (SDR) y “Universal Software Radio Peripherals” (USRP) en diferentes asignaturas del Grado de Ingenier´ıa Telem´atica de la Universitat de València
Phosphorylation Regulates CIRBP Arginine Methylation, Transportin-1 Binding and Liquid-Liquid Phase Separation
2021
Arginine-glycine(-glycine) (RG/RGG) regions are highly abundant in RNA-binding proteins and involved in numerous physiological processes. Aberrant liquid-liquid phase separation (LLPS) and stress granule (SGs) association of RG/RGG regions in the cytoplasm have been implicated in several neurodegenerative disorders. LLPS and SG association of these proteins is regulated by the interaction with nuclear import receptors, such as transportin-1 (TNPO1), and by post-translational arginine methylation. Strikingly, many RG/RGG proteins harbour potential phosphorylation sites within or close to their arginine methylated regions, indicating a regulatory role. Here, we studied the role of phosphoryla…
Innovación en docencia de sistemas de comunicación en el Grado de Ingeniería Telemática de la UVEG
2016
[EN] In teaching Communication Systems, we find a high theoretical component. The perception about the related subjects cause a negative perception in the students. This work explains the motivation and the strategy followed to re-orientate this perception by introducing Software Defined Radio elements (like USRPs) in different subjects in the Degree and the Master in Telecommunication Engineering at the University of Valencia
Mikrokokoistetut leviämisvastus- ja nelipisteanturimittaukset puolijohderakenteen varauksenkuljettajien syvyysjakaumien määrittämisessä
2013
Entistä pienemmät puolijohderakenteet vaativat analyysityökaluilta erittäin hyvää herkkyyttä, jonka on myös kehityttävä rakenteiden vaatimusten mukaisesti -- muussa tapauksessa kehitys voi hidastua hyvin paljon ilman kunnollista tietoa valmistusmenetelmien tuloksista. Yksi oleellinen osa rakenteiden analysoimisessa on tieto seostusatomien ja varauksenkuljettajien pitoisuuksista rakenteen syvyyssuunnassa, eli syvyysjakauma. Vuosikymmeniä syvyysjakauman mittaukseen on käytetty leviämisvastusmittausta (SRP, engl. Spreading Resistance Profiling), ja nelipisteanturimittausta (4PP, engl. Four Point Probe) on käytetty kuvaamaan koko syvyysjakauman vaikutusta sähköisessä kontaktissa. Molempien tekn…
Knockout of the KH-Type Splicing Regulatory Protein Drives Glomerulonephritis in MRL-Faslpr Mice
2021
KH-type splicing regulatory protein (KSRP) is an RNA-binding protein that promotes mRNA decay and thereby negatively regulates cytokine expression at the post-transcriptional level. Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by dysregulated cytokine expression causing multiple organ manifestations
Protein SRP54 iz morske spužve Geodia cydonium
2002
In the systematic search for phylogenetically conserved proteins in the simplest and most ancient extant metazoan phylum – Porifera, we have identified and analyzed a cDNA encoding the signal recognition particle 54 kD protein (SRP54) from the marine sponge Geodia cydonium (Demospongiae). The signal recognition particle (SRP) is a universally conserved ribonucleoprotein complex of a very ancient origin, comprising SRP RNA and several proteins (six in mammals). The nucleotide sequence of the sponge cDNA predicts a protein of 499 amino acid residues with a calculated Mr of 55175. G. cydonium SRP54 displays unusually high overall similarity (90 %) with human/mammalian SRP54 proteins, higher th…
Frequency-Sliding Generalized Cross-Correlation: A Sub-Band Time Delay Estimation Approach
2020
The generalized cross correlation (GCC) is regarded as the most popular approach for estimating the time difference of arrival (TDOA) between the signals received at two sensors. Time delay estimates are obtained by maximizing the GCC output, where the direct-path delay is usually observed as a prominent peak. Moreover, GCCs play also an important role in steered response power (SRP) localization algorithms, where the SRP functional can be written as an accumulation of the GCCs computed from multiple sensor pairs. Unfortunately, the accuracy of TDOA estimates is affected by multiple factors, including noise, reverberation and signal bandwidth. In this paper, a sub-band approach for time del…
Active learning in digital communications with low-cost software defined radio
2021
Las comunicaciones digitales se enseñan tradicionalmente en sesiones de laboratorio desde un punto de vista teórico, utilizando plataformas de simulación. Sin embargo, el sistema de Acreditación Académica incluye la dimensión de "lo que se espera que los estudiantes sean capaces de hacer", lo que plantea la necesidad de disminuir la brecha entre las sesiones de laboratorio simuladas y un enfoque más práctico y realista. En este trabajo, proponemos una metodología para mejorar el aprendizaje de los aspectos prácticos relacionados con los cursos de Comunicaciones Digitales, así como para aumentar la motivación de los estudiantes, mediante el uso de dispositivos de radio definida por software …
