Oleadas de energía. Una iniciativa sostenible para aprovechar la energía de mares y océanos.
2010
El objetivo de este trabajo es mostrar diferentes aplicaciones de la energía undimotriz como energía limpia y alternativa y construir un generador undimotriz piezoeléctrico capaz de aprovechar la energía de las olas para producir electricidad. Hoy en día existen multitud de prototipos que aprovechan el movimiento de las olas para producir energía eléctrica. Como es una tecnología relativamente joven los sistemas undimotrices tienen un margen de evolución muy grande. Algunos países ya tienen sistemas funcionando y conectados a la red eléctrica, como Portugal que ha apostado claramente por esta nueva energía renovable. Noruega y Escocia son países pioneros en la tecnología undimotriz. En Espa…
Production, oxidation traits and health of dairy ewes fed diets supplemented with fungus myceliated grains.
2019
Mushrooms contain many bioactive compounds, mainly poly- and oligosaccharides, known to have benefits for human health. Polysaccharides from mushrooms exhibited immunomodulatory, antibacterial, antiviral, and antifungal properties, as well as antitumor activity. Furthermore, some mushrooms showed to have potent antioxidant properties due to the presence of phenolic acids, flavonoids, polysaccharides, carotenoids, ascorbic acid, and tocopherols. These beneficial properties of mushrooms bioactive compounds indicate their potential use as performance-enhancing natural feed additives for livestock animals. In this regard, the use of mushrooms and mushroom-derived products has largely been inves…
The Fibronectin RGD and synergy sites function in integrin interaction
2018
Fibronectin (FN) is a large glycoprotein component of the extracellular matrix (ECM). It presents two forms: soluble in plasma or insoluble (fibrillar) within the ECM surrounding the cells in tissues. FN is one of the most important proteins in the ECM, it directly mediates cell adhesion, and therefore is essential for several biological processes such as embryonic development or blood clotting. Its involvement in these processes relay in its interaction with the cellular receptors integrins. The major binding site for integrins in FN is the so-called RGD site located in the 10th FN type III repeat (FNIII10), which is recognized by a5b1, aIIbb3 and all the av-containing integrins. Additiona…
Factors associated with milk urea concentrations in Girgentana goats
2010
A total of 1,481 milk samples of 166 Girgentana goats, taken along the entire lactation, were utilised to evaluate the effect of non nutritional factors on milk urea (MU). Parity, stage of lactation and month of sampling significantly influenced MU, while no effect was found for born kids number. The first kidding goats produced lower MU than multiparous goats. Trend of MU was similar to milk production course with a peak found at 60 DIM. The different MU levels between several months of production are often linked to pasture chemical variations.
Hipofīzes neiroendokrīno audzēju raksturīgo mikro RNS identificēšana un izpēte pacientu plazmā
2021
Cirkulējošās plazmas mikro RNS (miRNS) ir plaši pētīts biomarķieris ļaundabīgo audzēju diagnostikā, bet saistībā ar hipofīzes neiroendokrīnajiem audzējiem (PitNET) tās ir maz izpētītas. Darbā, izmantojot nākamās paaudzes sekvencēšanu, tika analizētas miRNS izmaiņas pacientu plazmas paraugos pirms un 24 stundas pēc ekstirpācijas, kā arī novērtēts miRNS saturs plazmā no pacienta, kuram tika veikta bilaterālā inferioro petrozālo sinusu katetrizācija (BIPSS). Pirms un pēc ekstirpācijas cirkulējošo miRNS sastāvs tika analizētas 34 pacientos un diferenciālekspresijas analīzē statistiski būtiskas izmaiņas (P < 0,05) 24 stundas pēc PitNET ekstirpācijas tika detektētas 22 miRNS, no kurām 15 bija aug…

Molecular mechanics models for the image charge, a comment on “including image charge effects in the molecular dynamics simulations of molecules on m…
2017
We re-investigate the image charge model of Iori and Corni (Iori and Corni, J. Comput. Chem. 2008, 29, 1656). We find that a simple symmetrization of their model allows to obtain quantitatively correct results for the electrostatic interaction of a water molecule with a metallic surface. This symmetrization reduces the magnitude of the electrostatic interaction to less than 10% of the total interaction energy. © 2017 Wiley Periodicals, Inc.
Nuevas metodologías en la reacción aza-Michael intramolecular organocatalítica
2022
La síntesis asimétrica es un área clave en la Química moderna, especialmente relevante en la industria farmacéutica dada la íntima relación entre la actividad biológica de las biomoléculas y su estereoquímica. Al mismo tiempo, la concienciación sobre la contaminación y los múltiples problemas que esta puede ocasionar, ha impulsado que estas metodologías sean más ecológicas y respetuosas con en el medio ambiente. En este sentido, la organocatálisis se ha revelado en los últimos años como una de las estrategias más interesantes para la obtención de compuestos enantioenriquecidos. En consecuencia, nuestro grupo de investigación se ha centrado en la aplicación de dicha estrategia a la reacción …
Measurement of the low-energy antideuteron inelastic cross section
2020
In this Letter, we report the first measurement of the inelastic cross section for antideuteron-nucleus interactions at low particle momenta, covering a range of $0.3 \leq p < 4$ GeV/$c$. The measurement is carried out using p-Pb collisions at a center-of-mass energy per nucleon-nucleon pair of $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV, recorded with the ALICE detector at the CERN LHC and utilizing the detector material as an absorber for antideuterons and antiprotons. The extracted raw primary antiparticle-to-particle ratios are compared to the results from detailed ALICE simulations based on the GEANT4 toolkit for the propagation of antiparticles through the detector material. The analysis of th…
