Historic exposure to herbivores, not constitutive traits, explains plant tolerance to herbivory in the case of two Medicago species (Fabaceae)
Altres ajuts: Direcció General de PolÃtica Università ria i Recerca (Govern de les Illes Balears) FPI/1925/2016Mechanisms that allow plants to survive and reproduce after herbivory are considered to play a key role in plant evolution. In this study, we evaluated how tolerance varies in species with different historic exposure to herbivores considering ontogeny. We exposed the range-restricted species Medicago citrina and its closely related and widespread species M. arborea to one and two herbivory simulations (80 % aerial biomass loss). Physiological and growth parameters related to tolerance capacity were assessed to evaluate constitutive values (without herbivory) and induced tolerance after damage. Constitutive traits were not always related to greater tolerance, and each species compensated for herbivory through different traits. Herbivory damage only led to mortality in M. citrina; adults exhibited root biomass loss and increased oxidative stress after damage, but also compensated aerial biomass. Despite seedlings showed a lower death percentage than adults after herbivory in M. citrina, they showed less capacity to recover control values than adults. Moderate tolerance to M. arborea herbivory and low tolerance to M. citrina is found. Thus, although the constitutive characteristics are maintained in the lineage, the tolerance of plants decreases in M. citrina. That represents how plants respond to the lack of pressure from herbivores in their habitat

Anà lisi del metabolisme ambiental de nuclis turÃstics litorals : el cas de Menorca
L'objectiu del present estudi és l'anà lisi del metabolisme energètic associat a nuclis turÃstics litorals de l'illa de Menorca (Mediterrani occidental) i el grau d'autosuficiència a partir d'energies renovables. La caracterització dels nuclis i la definició del perfil del turista s'ha realitzat mitjançant SIG i informació de qualitat a partir d'enquestes. Els principals resultats mostren que els nuclis turÃstics de Menorca tenen unes emissions associades entre 213 i 318 kg de CO2 per estada. De mitjana, el recorregut del turista fins a la illa (mobilitat externa) és de 1334 km (representant el 80% de les emissions), mentre que la mobilitat interna durant l'estada és de 22 km. A diari, cada turista consumeix entre 8 i 26 kWh d'electricitat, consum que es podria satisfer en un 100% amb la instal·lació de sistemes fotovoltaics a les cobertes del nucli.El objetivo del presente estudio es el análisis del metabolismo energético asociado a los núcleos turÃsticos litorales de la isla de Menorca (Mediterráneo occidental) y el grado de autosuficiencia a partir de energÃas renovables.

Atherosclerotic plaque destabilization in Mice: A comparative study
Atherosclerosis-Associated diseases are the main cause ofmortality and morbidity in western societies. The progression of atherosclerosis is a dynamic process evolving from early to advanced lesions thatmay become rupture-prone vulnerable plaques. Acute coronary syndromes are the clinical manifestation of life-Threatening thrombotic events associated with high-risk vulnerable plaques. Hyperlipidemic mouse models have been extensively used in studying the mechanisms controlling initiation and progression of atherosclerosis. However, the understanding of mechanisms leading to atherosclerotic plaque destabilization has been hampered by the lack of proper animalmodelsmimicking this process. Although various mouse models generate atherosclerotic plaques with histological features of human advanced lesions, a consensus model to study atherosclerotic plaque destabilization is still lacking. Hence, we studied the degree and features of plaque vulnerability in different mouse models of atherosclerotic plaque destabilization and find that the model based on the placement of a shear stress modifier in combination with hypercholesterolemia represent with high incidence the most human like lesions compared to the other models
Analizying MOOCs from an educational perspective in Spain
ABSTRACT: This article is the result of a Teaching Innovation Project funded by the University of Cantabria’s Vice-Rectorate for Teaching Staff. Its goals are to analyze the phenomenon of MOOCs with pedagogical criteria and to develop a Best Practice Guide. The project was developed by the Universities of Cantabria and Oviedo, all the work was divided into three phases: 1) Theoretical review and the design of classroom activities, 2) The implementation of classroom activities and analysis of the main results and 3) The development of a MOOC Best Practice Guide. The results of the second phase at the University of Cantabria are presented here. They demonstrate the need to introduce these massive open online courses into degree programmes in Education, updating higher education studies and providing valuable knowledge for understanding the educational potential (not just technological or financial) of this online training
Histone Deacetylase 9 Activates IKK to Regulate Atherosclerotic Plaque Vulnerability
Rationale: Arterial inflammation manifested as atherosclerosis is the leading cause of mortality worldwide. Genome-wide association studies have identified a prominent role of histone deacetylase 9 (HDAC9) in atherosclerosis and its clinical complications including stroke and myocardial infarction.
Objective: To determine the mechanisms linking HDAC9 to these vascular pathologies and explore its therapeutic potential for atheroprotection.
Methods and Results: We studied the effects of Hdac9 on features of plaque vulnerability using bone marrow reconstitution experiments and pharmacological targeting with a small molecule inhibitor in hyperlipidemic mice. We further employed two-photon and intravital microscopy to study endothelial activation and leukocyte-endothelial interactions. We show that hematopoietic Hdac9 deficiency reduces lesional macrophage content whilst increasing fibrous cap thickness thus conferring plaque stability. We demonstrate that HDAC9 binds to IKKα and β resulting in their deacetylation and subsequent activation, which drives inflammatory responses in both macrophages and endothelial cells. Pharmacological inhibition of HDAC9 with the class IIa HDAC inhibitor TMP195 attenuates lesion formation by reducing endothelial activation and leukocyte recruitment along with limiting pro-inflammatory responses in macrophages. Transcriptional profiling using RNA-Seq revealed that TMP195 downregulates key inflammatory pathways consistent with inhibitory effects on IKKβ. TMP195 mitigates the progression of established lesions and inhibits the infiltration of inflammatory cells. Moreover, TMP195 diminishes features of plaque vulnerability and thereby enhances plaque stability in advanced lesions. Ex vivo treatment of monocytes from patients with established atherosclerosis reduced the production of inflammatory cytokines including IL-1β and IL-6.
Conclusions: Our findings identify HDAC9 as a regulator of atherosclerotic plaque stability and IKK activation thus providing a mechanistic explanation for the prominence of HDAC9 as a vascular risk locus in genome-wide association studies. Its therapeutic inhibition may provide a potent lever to alleviate vascular inflammation
Environmental and self-sufficiency assessment of the energy metabolism of tourist hubs on Mediterranean Islands : the case of Menorca (Spain)
SostenipraEnergy performance of island tourism has been analyzed in the literature. However, tourist services tend to concentrate in tourist hubs, especially where mass tourism predominates (e.g., Mediterranean), and the energy metabolism of these systems has not yet been assessed. The present paper models and estimates the energy metabolism of tourist hubs in the Menorca Island (Spain) by integrating social, geographical and environmental methods. Mobility (both external and internal) and consumption of lodging services were characterized through surveys to users (tourists) and business managers. An environmental assessment evaluated COâ‚‚ emissions, and energy self-sufficiency potential was estimated via GIS data. The results indicate that, on average, a tourist consumes 4756 MJ with associated emissions of 277 kg of COâ‚‚ per stay (20 days on average). Of all the energy flows, external mobility contributes the most to total emissions (77%). For every day spent in a tourist hub, a tourist consumes between 29 MJ and 93 MJ in lodging services, consumption that could be 100% satisfied by photovoltaic systems, and these systems would result in positive effects for the island. Sustainable tourism management might focus on promoting environmentally friendly transportation, energy efficient practices, and environmental communication through ecolabeling
