Reviewing lymnaeid vectors of fascioliasis by ribosomal DNA sequence analyses.
2005
AbstractSnails of the family Lymnaeidae are of great parasitological importance due to the numerous helminth species they transmit, mainly trematodiases (such as fascioliasis) of considerable medical and veterinary impact. The present knowledge of the genetics and host–parasite relationships of this gastropod group is far from adequate. Fascioliasis is caused by two species, Fasciola hepatica and F. gigantica, which, as in the case of other trematodes, show a marked snail host specificity. Many lymnaeid species involved in fascioliasis transmission still show a confused systematic-taxonomic status. The need for tools to distinguish and characterize species and populations of lymnaeids is ev…
Use of amitriptyline for the treatment of chronic tension-type headache : review of the literature
2008
Amitriptyline is a tricyclic antidepressant, considered the treatment of choice for different types of chronic pain, including chronic myofascial pain. Its antinociceptive property is independent of its antidepressant effect. Although its analgesic mechanism is not precisely known, it is believed that the serotonin reuptake inhibition in the central nervous system plays a fundamental role in pain control. Although this medication is widely used in the prevention of chronic tension-type headache, few studies have investigated the efficacy of this treatment and the published results are contradictory. The objective of this article was to review the literature published on the use of amitripty…
Use of Different Food Classification Systems to Assess the Association between Ultra-Processed Food Consumption and Cardiometabolic Health in an Elde…
2021
The PREDIMED-Plus trial was supported by the European Research Council (Advanced Research grant 2014–2019; agreement #340918; granted to M.Á.M.-G.); the official Spanish institutions for funding scientific biomedical research, CIBER Fisiopatología de la Obesidad y Nutrición (CIBEROBN) and Instituto de Salud Carlos III (ISCIII) through the Fondo de Investigación para la Salud (FIS) which is co-funded by the European Regional Development Fund (coordinated FIS projects led by J.S-S. and J.V., including the following projects: PI13/00673, PI13/00492, PI13/00272, PI13/01123, PI13/00462, PI13/00233, PI13/02184, PI13/00728, PI13/01090, PI13/01056, PI14/01722, PI14/00636, PI14/00618, PI14/00696, PI…
Effects of ions on water structure: a low-field (1) H T1 NMR relaxometry approach
2014
Aqueous salt solutions play an important role in nature because of their effects on environmental biogeochemical processes and on structural properties of biomolecules. Upon dissolution, salts split in ions that are solvated. Water in hydration shells is subjected to molecular motions that can be monitored by (1) H T1 NMR relaxometry. This technique allowed the evaluation of the nature of the interactions between water and ions via variable temperature experiments. Examination of relaxometry properties of aqueous solutions at variable salt concentrations allowed acknowledgement of the role played by ions in either structuring or destructuring water aggregates. A mathematical model has been …
ULTRA-BROADBAND COHERENT DETECTION OF TERAHERTZ PULSES VIA CMOS-COMPATIBLE SOLID-STATE DEVICES
Il presente lavoro di tesi presenta e dimostra una tecnica innovativa e completamente integrata dedita alla rilevazione coerente di radiazioni a frequenze Terahertz (THz), cioè di onde elettromagnetiche il cui contenuto frequenziale cade convenzionalmente nella finestra spettrale compresa tra 0.1-10x1012 Hz. Tale tecnica è stata battezzata col nome di solid-state-biased coherent detection (SSBCD), dal momento che essa sfrutta le proprietà di un mezzo a stato solido e consente di ricostruire simultaneamente l’informazione sulla fase e sull’ampiezza degli impulsi THz, anche nel caso in cui quest’ultimi siano dotati di spettri a banda cosiddetta “ultra larga” (> 10 THz). Tale metodo di rivelaz…
Descripción anatómica del espacio rectogenital: fascia de Denonvilliers y espacio rectovaginal
2015
Desde el siglo pasado hasta la actualidad persiste un debate con respecto a la posible existencia y composición de un septo rectovaginal independiente situado medialmente entre la pared rectal y la vaginal. Se ha creído que el septo rectovaginal representa el análogo femenino de la fascia masculina prostato-perineal descrita por primera vez por el anatomista francés Denonvilliers en 1836. Asimismo, ha existido un largo debate acerca de la existencia, definición y composición de la fascia de Denonvilliers. Existe controversia acerca de si es posible identificar esta estructura durante una cirugía in vivo, así como de sus relaciones exactas con la fascia propia del recto y en cuál es el plano…
Improving the Performance of Steel Machining Processes through Cutting by Vibration Control
2021
Machining processes through cutting are accompanied by dynamic phenomena that influence the quality of the processed surfaces. Thus, this research aimed to design, make, and use a tool with optimal functional geometry, which allowed a reduction of the dynamic phenomena that occur in the cutting process. In order to carry out the research, the process of cutting by front turning with transversal advance was taken into account. Additionally, semi-finished products with a diameter of Ø = 150 mm made of C45 steel were chosen for processing (1.0503). The manufacturing processes were performed with the help of two tools: a cutting tool, the classic construction version, and another that was the i…
The dynamics of a developing CW supercontinuum: Analytical predictions and experiments
2010
International audience; We show that the development of the supercontinuum spectrum in the quasi-CW regime can be interpreted analytically in terms of Akhmediev Breathers. Theory and experiment are in excellent agreement.
Proyecto de Innovación Educativa 2014 del Laboratorio de Termodinámica (PIE2014LT)
2015
El objetivo del proyecto de Innovación Educativa 2014 del Laboratorio de Termodinámica (PIE2104LT) es mejorar la enseñanza y aprendizaje de los conceptos fundamentales de física que son objeto de estudio en el Laboratorio de Termodinámica en sus aspectos experimentales y en sus descripciones teóricas, tanto desde la perspectiva macroscópica como microscópica. Para ello se plantea el desarrollo de una nueva metodología para la docencia en el Laboratorio de Termodinámica basada en la comparación de observaciones experimentales reales y sus correspondientes versiones virtuales. La experiencia adquirida en este proyecto y en su antecesor, PIE2013LT, está demostrando que esta metodología docente…
Health-Improved Textiles Obtained by Heat Surface Ecodyeing Treatments
2015
The central idea of the present research aims at achieving textile substrates through an efficient inclusion of a wild black cherry extract into the grafting agent-monochlorotriazinyl-β-cyclodextrin (MCT-β-CD). The methodology consists in a permanent/irreversible entrapment onto the fibres surface of the natural extract through inclusion mechanism. Exhaustion and sonication dyeing procedures were used alternatively. The obtained materials were characterized, by FT-IR and BET analysis. The experimental results reveal good adsorptive feature of the samples, due to a higher specific surface created by the inclusion complex (MCT-β-CD-dye pigment). An efficient blocking of the natural dye pigmen…
