Evaluación morfológica y morfométrica de neuroimágenes retinianas y cerebrales como factor pronóstico de la función visual en pacientes con esclerosi…
2013
El propósito de esta tesis doctoral es estudiar la proporción de pérdida neurológica en el tiempo a nivel cerebral y retiniano en relación con la deficiencia sensorial y motora en pacientes diagnosticados de esclerosis múltiple. La muestra está constituida por 35 pacientes clasificados en tres grupos en función del subtipo de enfermedad (síndromes clínicos aislados, formas remitentes-recurrentes y formas progresivas) diagnosticados de esclerosis múltiple según los criterios de McDonald, aunque a efectos del análisis estadístico, las unidades de observación fueron los 70 ojos correspondientes. Se recopiló información mediante la anamnesis y revisión de la historia clínica de los pacientes re…
Puntos de encuentro musicales a las orillas del Mediterráneo: Nápoles y Valencia (ca. 1450-1550)
2000
Síntesis ponderativa de la espléndida capilla musical que el rey Alfonso el Magnánimo portó consigo a Nápoles: predominancia de cantantes hispanos y francoflamencos, sus compositores y su repertorio (deducible). El cambio de orientación impresa por el sucesor Ferrante I y la recuperación de aquélla del Duque de Calabria en Valencia.
Sleep–wake problems in patients with amyotrophic lateral sclerosis: implications for patient management
2012
SUMMARY Sleep–wake problems are frequent, although unrecognized, complications of amyotrophic lateral sclerosis (ALS). Sleep disorders such as insomnia, sleep-disordered breathing and restless legs syndrome have all been reported in patients with ALS, despite the limited number of studies and the small populations investigated so far. Sleep disturbances gradually worsen with disease progression, suggesting a relationship between the severity of disease and the neurodegenerative process. However, poor sleep can also be a consequence of several disturbances such as anxiety, depression, pain, choking, sialorrhea, fasciculations, cramps, nocturia and the inability to get comfortable and move f…
Aircraft wing rock oscillations suppression by simple adaptive control
2020
Abstract Roll angular motion of the modern aircraft operating in non-linear flight modes with a high angle of attack often demonstrates the limit cycle oscillations, which is commonly known as the wing rock phenomenon. Wing rock dynamics are represented by a substantially non-linear model, with parameters varying over a wide range, depending on the flight conditions (altitude, Mach number, payload mass, etc.) and angle of attack. A perspective approach of the wing rock suppression lies in the adaptation methods. In the present paper an application of the simple adaptive control approach with the Implicit Reference Model (IRM) is proposed and numerically studied. The IRM adaptive controller …

By the possession of unique exocrine scent glands, Opiliones (harvestmen) arise as a perfect model for studies on the evolutionary history of secretion chemistry. Among gland compounds of harvestmen, it is the quinones that represent recurring elements across the secretions of all suborders. Reliable data on quinone-distribution, however, is only known for Laniatores (benzoquinones) and Cyphophthalmi (naphthoquinones). We here unraveled the quinone-distribution across scent gland secretions of the third large harvestman suborder, the Palpatores (= Eu- and Dyspnoi): Naphthoquinones were found in phalangiid Eupnoi across all subfamilies as well as in nemastomatid (and at least one ischyropsal…
Persistent inflammation alters the function of the endogenous brain stem cell compartment
2008
Endogenous neural stem/precursor cells (NPCs) are considered a functional reservoir for promoting tissue homeostasis and repair after injury, therefore regenerative strategies that mobilize these cells have recently been proposed. Despite evidence of increased neurogenesis upon acute inflammatory insults (e.g. ischaemic stroke), the plasticity of the endogenous brain stem cell compartment in chronic CNS inflammatory disorders remains poorly characterized. Here we show that persistent brain inflammation, induced by immune cells targeting myelin, extensively alters the proliferative and migratory properties of subventricular zone (SVZ)-resident NPCs in vivo leading to significant accumulation…

Atherogenic dyslipidemia and oxidative stress: a new look
2009
Although results from in vitro studies and clinical trials demonstrate strong associations between oxidative stress and cardiovascular risk, to date still no convincing data are available to suggest that treatment with antioxidants might reduce vascular events. Oxidative modifications of low-density lipoproteins (LDL) represent an early stage of atherosclerosis, and small, dense LDL are more susceptible to oxidation than larger, more buoyant particles. Oxidized LDL are independent predictors of subclinical and clinical atherosclerosis. Recent studies suggested that novel therapeutic strategies may take into account the removal of such particles from circulation. Future research is required …
Concentrations, composition, and sources of ice-nucleating particles in the Canadian High Arctic during spring 2016
2019
Modelling studies suggest that the climate and the hydrological cycle are sensitive to the concentrations of ice-nucleating particles (INPs). However, the concentrations, composition, and sources of INPs in the atmosphere remain uncertain. Here, we report daily concentrations of INPs in the immersion freezing mode and tracers of mineral dust (Al, Fe, Ti, and Mn), sea spray aerosol (Na+ and Cl−), and anthropogenic aerosol (Zn, Pb, NO3-, NH4+, and non-sea-salt SO42-) at Alert, Canada, during a 3-week campaign in March 2016. In total, 16 daily measurements of INPs are reported. The average INP concentrations measured in the immersion freezing mode were 0.005±0.002, 0.020±0.004, and 0.186±0.040…
Abstención sexual durante la Cuaresma en Andalucía a lo largo del siglo XX y su impacto en la estacionalidad de los nacimientos
2018
Durante siglos ha permanecido vigente en las poblaciones católicas un precepto religioso que prohibía las relaciones sexuales durante la Cuaresma. Esta interdicción repercutía en una disminución de concepciones y en un repunte tras dicho periodo, ambos difíciles de detectar porque, en poblaciones que no ejercían un control efectivo de la fecundidad, también se registraba un pico de concepciones durante la primavera. En la actualidad este precepto ha desaparecido como consecuencia de un proceso de erosión que no conocemos suficientemente. Con los datos anonimizados de todas las personas nacidas en Andalucía y supervivientes a 1 de enero de 2003 (n=8.397.206), este trabajo pretende determinar…
