Absorption of oxybutynin from vaginal inserts: drug blood levels and the response of the rabbit bladder.
2000
Abstract Objectives. Oxybutynin has been used for treatment of urge urinary incontinence for more than 20 years. However, one of the major problems with its use is uncomfortable anticholinergic side effects that can lead to discontinuation of treatment. Alternative forms of drug administration may reduce side effects and thus improve patient compliance. Methods. A cylinder-shaped, curved silicone elastomer insert containing oxybutynin was anchored in the vagina of female rabbits. The inserts were designed to release oxybutynin at rates of 0.5, 1.0, and 5.0 mg/day, respectively. Blood drug and metabolite levels were monitored for 1 to 7 days and cystometry was carried out after 7 days of tre…
Análisis y validación de una rúbrica para evaluar habilidades de presentación oral en contextos universitarios
2017
Introducción. Este trabajo analiza la validez convergente entre la evaluación sumativa de las habilidades de comunicación oral con apoyo visual de estudiantes universitarios efectuada por el profesorado y por los pares a través de la aplicación de una rúbrica.Método. Se analiza el nivel de convergencia entre las valoraciones efectuadas por el profesorado y por los pares desde una perspectiva analítica –criterio a criterio- y holística –puntuación global-. La percepción de validez y utilidad se determina a partir de las valoraciones efectuadas por los estudiantes sobre ambos aspectos en relación a la rúbrica desarrollada.Resultados. Los estudiantes señalan que la rúbrica resulta útil para ex…
Características sociales y clínicas de un grupo de madres infectadas por VIH en Valencia: influencia de la drogadicción parenteral
2000
Resumen Objetivo Al principio de conocerse la infeccion por el virus de la inmunodeficiencia humana (VIH), la causa mas importante de su transmision en las mujeres occidentales fue el consumo de drogas por via parenteral. El objetivo de nuestro trabajo consistio en describir las principales caracteristicas sociales y clinicas de un grupo de madres seropositivas, y en analizar su relacion potencial con el uso intravenoso de drogas. Metodos Realizamos un estudio observacional prospectivo con 220 mujeres infectadas por VIH que presentaban la particularidad de haber dado a luz ninos con riesgo de infeccion. Se incluyeron todas las madres reclutadas en la Unidad VIH de un hospital de Valencia qu…
Some genotypic and environmental conditions of the host in cutaneous malignant melanoma
2006
The factors involving the development of melanoma vary according to the phenotype and environment conditions experienced by the host MC1R variant alleles that are associated with increased melanoma risk are likely to sensitize melanocytes to DNA damage by ultraviolet (UV) exposure, and the interactions between UV radiation and the genome induce melanoma. In fact, the non-functional MC1R cells have a very slow rate of cyclobutane pyrimidine dimers removal. The most significant mutations induced by UV in the skin occur in the CDKN2A gene being the major target of UV, that encodes 2 distinct proteins cell cycle regulators: p16INK4A and p14ARF. Inactivation of both tumor suppressors results in …

A survey on peer-to-peer SIP based communication systems
2010
Published version of an article from the journal: Peer-to-Peer Networking and Applications. The original publication is available at Spingerlink. http://dx.doi.org/10.1007/s12083-009-0064-4 Recently, both academia and industry have initiated research projects directed on integration of P2PSIP paradigm into communication systems. In this paradigm, P2P network stores most of the network information on each participating peer without help of the central servers. The concept of self-configuration, self-establishment greatly improves the robustness of the network system compared with the traditional Client/Server based systems. In this paper, we survey P2PSIP solutions proposed recently both in …
The effect of Mo and Ge reactive elements on high-temperature oxidation of higher manganese silicide
2021
Abstract Higher manganese silicide (HMS) alloys (Mnx-αMoαSiy-βGeβ (x = 0.99–1.011, α = 0.005–0.02, y = 1.75, β = 0.005–0.01)) were studied to elucidate the effect of Mo and Ge pertaining to oxidation. Oxidation experiments were conducted using thermogravimetry and characterized using x-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Isoconversion experiments below 450 °C, shows that doping (up to 2 at%) raises the oxidation potential of HMS. Isothermally, the oxidation rate reduces buy one order of magnitude by doping on Mn and/or Si sites from 0.5 to 2 at%, revealing that the dopants-based oxides do not lessen the robustness of SiO2 oxide.

Josephson Traveling Wave Parametric Amplifiers as Non-Classical Light Source for Microwave Quantum Illumination
2021
Abstract Detection of low-reflectivity objects can be enriched via the so-called quantum illumination procedure. In order that this quantum procedure outperforms classical detection protocols, entangled states of microwave radiation are initially required. In this paper, we discuss the role of Josephson Traveling Wave Parametric Amplifiers (JTWPAs), based on circuit-QED components, as suitable sources of a two-mode squeezed vacuum state, a special signal-idler entangled state. The obtained wide bandwidth makes the JTWPA an ideal candidate for generating quantum radiation in quantum metrology and information processing applications.
