Cristina Castellote i Bargalló. 1981.D'entre els tractaments d'utilitat clínica més notoria de l'asma extrínseca, patología molt comú. a la nostra ciutat i que afecta amb molta freqüencia a la població infantil, és de destacar la hiposensibilització especlfica en front l'al.lergen desencadenant. Actualment, s'admet la teoria segons la qual el mecanisme d'acció
d'aquesta immunoterápia, comporta la formació d'anticossos bloquejants corresponents a la classe IgG i que actuen competitivament amb la IgE especifica per al mateix al.lerge

Interaction dynamics between a contaminated dredged sediment and extracting solutions of different nature
No full text[Purpose]: The purpose of this work is to study the dynamics between the matrix of a contaminated marine sediment, its contaminants and various desorbing solutions by means of equilibrium tests, sedimentation trials and zeta potential, with the focus on assessing optimum enhancing solutions for decontamination purposes.[Materials and methods]: The sediment samples were analysed to determine their physico-chemical characteristics: particle size distribution, solids concentration, total organic carbon (TOC), content of heavy metals, organic contaminants, mineralogical phases, zeta potential and buffer capacity. Twelve extracting solutions of different nature were used for equilibrium tests, in which the dynamic behaviour of the sediment was evaluated. Elemental analysis was carried out for the sediment samples and the solutions before and after the tests.[Results and discussion]: The sediment was mainly composed of clay and lime, with a high content of iron, which has a strong influence on sorption-desorption processes. The sediment had a considerable buffer capacity at low and high pH values. The desorption of the metals was not proportional to pH. The highest decrease in the concentration of metals from the sediment was obtained with 0.2 M ethylenediaminetetra-acetic acid (EDTA) and 1 M nitric acid, while the lowest degree of metal extraction occurred in pure water and potassium iodide (KI).[Conclusions]: The most important parameters for contaminant release were complexation ability of the solution for the sediment components and pH of the solution. A promising design for the remediation treatment for the investigated sediment includes complexation and strong acid agents.The authors want to acknowledge the support of the Community of Madrid through the program “Garantía Juvenil” for the doctoral grant of the first author of this research.Peer reviewe

Achieving underwater noise regulation through an ecosystem-based approach: the “Mediterranean strategy on Underwater Noise Monitoring”.
No full textThe Contracting Parties to the Barcelona
Convention are considering the issue of underwater noise pollution under the
ongoing implementation of the Ecosystems Approach process (EcAp, Decision
17/6). In order to assess the environmental status of the Mediterranean, eleven
Ecological Objectives (EOs), and respective operational objectives and indicators
have been agreed through Decision 20/4 during the 17th Meeting of Contracting
Parties (COP 17). In line with the Marine Strategy Framework Directive of the
European Union (2008/56/EC), the overarching principle of the EcAp is the
achievement of the Good Environmental Status (GES). According to the definition
contained in the Decision 20/4, GES related to EO11 is achieved when noise from
human activities causes no significant impact on marine and coastal ecosystems.
In this context, the Agreement on the Conservation of Cetaceans of the Black Sea,
the Mediterranean Sea and the contiguous Atlantic area (ACCOBAMS), in
accordance with the Secretariat of the UNEP/MAP, launched a study to develop a
basin-wide strategy for underwater noise monitoring in the Mediterranean. The
present paper outlines the main elements of the Mediterranean strategy on
underwater noise monitoring
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The StartReact Effect on Self-Initiated Movements
No full textCopyright © 2013 J. M. Castellote et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.Preparation of the motor system for movement execution involves an increase in excitability of motor pathways. In a reaction time task paradigm, a startling auditory stimulus (SAS) delivered together with the imperative signal (IS) shortens reaction time significantly. In self-generated tasks we considered that an appropriately timed SAS would have similar effects. Eight subjects performed a ballistic wrist extension in two blocks: reaction, in which they responded to a visual IS, and action, in which they moved when they wished within a predetermined time window. In 20–25% of the trials, a SAS was applied. We recorded electromyographic activity of wrist extension and wrist movement kinematic variables. No effects of SAS were observed in action trials when movement was performed before or long after SAS application. However, a cluster of action trials was observed within 200 ms after SAS. These trials showed larger EMG bursts, shorter movement time, shorter time to peak velocity, and higher peak velocity than other action trials ( for all), with no difference from Reaction trials containing SAS. The results show that SAS influences the execution of self-generated human actions as it does with preprogrammed reaction time tasks during the assumed building up of preparatory activity before execution of the willed motor action
