Ethnobotanical uses of wild taxa as galactagogues in Sicily (Italy)
2018
<p>Breastfeeding furnishes optimal nutrition, immune support, and a multitude of health benefits to mothers and newborns. Since ancient times plants have been employed as galactagogues in the folk medicine of many human cultures. In Sicily, a region with great floristic diversity in the Mediterranean area, where a conspicuous pool of species is traditionally used for food and aromatic, cosmetic, handicraft, agricultural, forestry, and medicinal purposes, some people recognize the galactagogue properties of some spontaneous plants.</p><p>The goal of this study was to identify wild plants with galactagogue properties and vegetable-food remedies traditionally used by women du…
A contribution to the knowledge of myxomycetes diversity in volcanic islands
2015
A list of myxomycetes collected in Pantelleria, a volcanic island located 110 km southwest of the island of Sicily ( Italy), is presented with data on distribution. Forty-nine taxa were identified, 38 of which are new for Sicily. The myxomycete diversity of Pantelleria was also compared with that of other volcanic islands located in the Atlantic and Pacific oceans.

The impact of rituximab infusion protocol on the long-term outcome in anti-MuSK myasthenia gravis
2018
ObjectiveTo evaluate whether the clinical benefit and relapse rates in anti-muscle-specific kinase (MuSK) myasthenia gravis (MG) differ depending on the protocol of rituximab followed. MethodsThis retrospective multicentre study in patients with MuSK MG compared three rituximab protocols in terms of clinical status, relapse, changes in treatment, and adverse side effects. The primary effectiveness endpoint was clinical relapse requiring a further infusion of rituximab. Survival curves were estimated using Kaplan-Meier methods and survival analyses were undertaken using Cox proportional-hazards models. ResultsTwenty-five patients were included: 11 treated with protocol 4 + 2 (375 mg/m(2)/4 w…
Analytical solution of kinematic wave time of concentration for overland flow under green-ampt infiltration
2015
In this paper the well-known kinematic wave equation for computing the time of concentration for impervious surfaces has been extended to the case of pervious hillslopes, accounting for infiltration. An analytical solution for the time of concentration for overland flow on a rectangular plane surface is derived using the kinematic wave equation under the Green-Ampt infiltration. The relative time of concentration is defined as the ratio between the time of concentration of an infiltrating plane and the soil sorptivity time scale, depending on the normalized rainfall intensity and a parameter synthesizing the soil and hillslope characteristics. It is shown that for a more complex case (corre…
Design and synthesis of optical sensors for the detection of molecules with biological activity
2015
A la present tesi doctoral, titulada “Disseny i síntesi de sensors òptics per a la detecció de molècules amb activitat biològica”, s’han utilitzat diferents conceptes de la química supramolecular per a preparar compostos capaços de senyalitzar macroscópicament la presència de molècules tòxiques o actives biològicament. Així, s’han preparat quimio-sensors i quimiodosímetres per a la detecció d’anions, sals, zwitterions i agents de guerra química tal i com agents nerviosos i agents sanguinis. Addicionalment, es descriu el disseny i la construcció d’un aparell electrònic per a la monitorització automàtica d’aquests compostos. La tesi té un capítol introductori on s'expliquen els conceptes bàsi…

Polyester microplastic fibers affect soil physical properties and erosion as a function of soil type
2021
Microplastics are recognized as a factor of global change contaminating many environmental compartments. Agricultural soils are very likely to receive microplastic contamination and are of particular concern due to their role in food production. Microplastic fibers have already been shown to be able to affect soil properties, but their effect on different soil types is poorly understood. Moreover, limited information is available on how the presence of this pollutant can affect soil water erosion processes, which are extremely important issues in many environments. In the light of this, we performed two experiments (carried out on a microscale) to investigate how the presence of polyester m…
Valor pronóstico de la resonancia magnética cardiaca tras un infarto agudo de miocardio con elevación del segmento ST
2011
INTRODUCCIÓN Las enfermedades cardiovasculares, y en concreto el infarto agudo de miocardio con elevación de ST (IAMEST) son una importante causa de mortalidad en los países desarrollados. La resonancia magnética cardiaca (RMC) es una técnica cada vez más usada tras un IAMEST, permite un análisis simultáneo y fiable de varios índices cardiacos, que han demostrado valor para predecir la recuperación de la función sistólica. No obstante, los datos sobre su valor pronóstico son escasos y no hay estudios que realicen un análisis exhaustivo de todos los índices. Esta información es imprescindible para que la RMC se incorpore definitivamente a nuestra práctica clínica habitual. OBJETIVOS - Valora…
Aportación de la radioterapia guiada por la imagen al tratamiento del cáncer de próstata
2010
Objetivo: Demostrar que la verificación mediante Cone Beam CT (CBCT) en una serie de pacientes tratados con radioterapia externa 3D (RTE3D) por su cáncer de próstata (CP) se relaciona con una reducción de los niveles de toxicidad aguda y tardía. Material y Métodos: Se ha realizado un estudio retrospectivo no aleatorizado de 2 grupos homogéneos de pacientes tratados entre 2005 y 2008, 46 pacientes verificados mediante Electronic Portal Devices (EPIC) y 48 verificados mediante CBCT (Electa Synergy), con una mediana de edad de 67 años (42-85 años). Recibieron RTE3D por CP estadio localizado ( T1-T3b N0 M0 ), prescribiéndose las mismas dosis, simulados y planificados con los mismos criterios y …
Extent and persistence of soil water repellency induced by pines in different geographic regions
2018
The extent (determined by the repellency indices RI and RIc) and persistence (determined by the water drop penetration time, WDPT) of soil water repellency (SWR) induced by pines were assessed in vastly different geographic regions. The actual SWR characteristics were estimated in situ in clay loam soil at Ciavolo, Italy (CiF), sandy soil at Culbin, United Kingdom (CuF), silty clay soil at Javea, Spain (JaF), and sandy soil at Sekule, Slovakia (SeF). For Culbin soil, the potential SWR characteristics were also determined after oven-drying at 60°C (CuD). For two of the three pine species considered, strong (Pinus pinaster at CiF) and severe (Pinus sylvestris at CuD and SeF) SWR conditions we…
