12q21 Interstitial Deletions: Seven New Syndromic Cases Detected by Array-CGH and Review of the Literature.
2022
Interstitial deletions of the long arm of chromosome 12 are rare, with a dozen patients carrying a deletion in 12q21 being reported. Recently a critical region (CR) has been delimited and could be responsible for the more commonly described clinical features, such as developmental delay/intellectual disability, congenital genitourinary and brain malformations. Other, less frequent, clinical signs do not seem to be correlated to the proposed CR. We present seven new patients harboring non-recurrent deletions ranging from 1 to 18.5 Mb differentially scattered across 12q21. Alongside more common clinical signs, some patients have rarer features such as heart defects, hearing loss, hypotonia an…
Application of Electronic Nose for Evaluation of Wastewater Treatment Process Effects at Full-Scale WWTP
2019
This paper presents the results of studies aiming at the assessment and classification of wastewater using an electronic nose. During the experiment, an attempt was made to classify the medium based on an analysis of signals from a gas sensor array, the intensity of which depended on the levels of volatile compounds in the headspace gas mixture above the wastewater table. The research involved samples collected from the mechanical and biological treatment devices of a full-scale wastewater treatment plant (WWTP), as well as wastewater analysis. The measurements were carried out with a metal-oxide-semiconductor (MOS) gas sensor array, when coupled with a computing unit (e.g., a computer with…
Cancer Signaling Transcriptome Is Upregulated in Type 2 Diabetes Mellitus
2020
We aimed to explore the differences in the whole transcriptome of peripheral blood mononuclear cells between elderly individuals with and without type 2 diabetes (T2D). We conducted a microarray-based transcriptome analysis of 19 individuals with T2D and 15 without. Differentially expressed genes according to linear models were submitted to the Ingenuity Pathway Analysis system to conduct a functional enrichment analysis. We established that diseases, biological functions, and canonical signaling pathways were significantly associated with T2D patients when their logarithms of Benjamini&ndash
Estuio y caracterización de un perfil de miRNAs en el líquido peritoneal de pacientes con endometriosis para su posterior validación como herramienta…
2023
Se trata de un estudio retrospectivo, donde hemos descrito el contenido de miRNAs del líquido peritoneal de una cohorte de pacientes, por medio de dos procedimientos. Por una parte se han realizado arras de expresión para hacer un estudio previo y determinar que miRNAs se encontraban diferentemente expresados en el líquido peritoneal de las pacientes respecto de las controles. Posteriormente se ha llevado a cabo la segunda parte del estudio, validando por medio de la técnica RT-PCR aquellos micros diferentemente expresados. Hemos seleccionado los miRNAs que presentaban un particular interés en la etiopatogenia de la endometriosis. Así mismo también se han medido el contenido de diversos met…
A multi-input, single-inductor power system for multisource energy harvesting
2013
Today, energy harvesting is drawing a great deal of attention due to modern trends in energy saving and sustainable development purposes. Among renewable energy sources fuel cells and photovoltaic arrays are the most promising for a wide variety of applications, ranging from few mWatts of wireless sensor networks to kWatts for household appliances. Coupling several harvesters and renewable sources is the winning strategy to ensure a proper supply overcoming the uncertainty and limited availability of common harvesters and renewable sources. Multisource energy harvesting is actually an open research topic involving several pressing and often conflicting requirements. System cost, complexity,…
A High-Efficiency Optical Energy Harvester based on a Low-Impedance Plasmonic Nanoantenna
2022
In this paper, for the first time, an investigation in terms of efficiency of an energy harvester based on a plasmonic nanorectenna array is proposed. The novel proposed mirrored-arrowhead nanoantenna presents a very low impedance value at the resonant frequency which reduces the mismatching between the antenna and rectifier circuit. Simulation results carried out by the CST 2020 Studio show a resistance value equal to 1.1 kohms at about 350 THz and a very wide bandwidth as the equivalent RF rhombic antenna. This study paves the way to nanoantennas for high-efficiency electromagnetic energy harvesting applications overcoming the photovoltaic technology.
FPGA-based Acceleration of Detecting Statistical Epistasis in GWAS
2014
Abstract Genotype-by-genotype interactions (epistasis) are believed to be a significant source of unexplained genetic variation causing complex chronic diseases but have been ignored in genome-wide association studies (GWAS) due to the computational burden of analysis. In this work we show how to benefit from FPGA technology for highly parallel creation of contingency tables in a systolic chain with a subsequent statistical test. We present the implementation for the FPGA-based hardware platform RIVYERA S6-LX150 containing 128 Xilinx Spartan6-LX150 FPGAs. For performance evaluation we compare against the method iLOCi[9]. iLOCi claims to outperform other available tools in terms of accuracy.…
FLUMO: FLexible Underwater MOdem
2019
The last years have seen a growing interest in underwater acoustic communications because of its applications in marine research, oceanography, marine commercial operations, the offshore oil industry and defense. High-speed communication in the underwater acoustic channel has been challenging because of limited bandwidth, extended multipath, refractive properties of the medium, severe fading, rapid time variation and large Doppler shifts. In this paper, we show an implementation of a flexible Software-Defined Acoustic (SDA) underwater modem, where modulation parameters are completely tunable to optimize performance. In particular, we develop the system architecture following two key ideas. …
Nuevas Posibilidades Terapéuticas en el Fallo de Implantación
2015
RESUMEN DE TESIS DOCTORAL Hipótesis: El fallo de implantación (FI) se define como la ausencia de gestación en pacientes con ≥ 3 ciclos previos de fecundación in vitro (FIV) con transferencia en fresco de al menos 2 embriones en cada ciclo. En el FI podrían jugar un papel importante tanto factores embrionarios como endometriales. Se han utilizado distintas estrategias de tratamiento a nivel de laboratorio FIV. Esto incluye transferencia en día 3, cultivo prolongado y transferencia en estadio de blastocisto utilizando el método co-cultivo, hatching asistido, diagnóstico genético preimplantacional (DGP) o donación de ovocitos (ovodon). El PGS se está convirtiendo en un procedimiento habitual e…
