A nivel de políticas en salud todavía hay una importante brecha que completar. En 2010, ya el estigma era parte de los temas definidos en la Estrategia Nacional de Salud, dentro del eje estratégico de “Enfermedades no transmisibles, violencia y discapacidad”, bajo el resultado esperado “Promover la inclusión social de las personas con discapacidad de origen mental”, por ejemplo, se plateó el resultado de “Contar con un plan regional para reducir estigma hacia personas con problemas o trastornos mentales”. Si bien esto movilizó algunos desarrollos regionales, esto no alcanzó a todo el país. Por esta razón, el Plan Nacional de Salud Mental 2017-2025 volvió a retomar el tema. Esta vez, asignándole mayor prioridad, lo cual queda plasmado en el plan de acción asociado, donde la materia tiene una línea específica. El objetivo de la línea es “reducir el estigma relacionado a problemas de salud mental” y cuenta entre sus principales iniciativas con: • Diseñar e implementar un plan para abordar el estigma relacionado con la salud mental • Desarrolla un levantamiento sistemático de información acerca de buenas prácticas sobre estigma en la salud mental, en la red de salud, la sociedad civil y el mundo académico. • Realizar un Diagnóstico de estigma asociado a salud mental en población seleccionada[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Cumplo un rol de Investigador Asociado. Which are the molecular and physiological mechanisms involved in priming and defense activation in cherry plants upon Pss infection? Are these mechanisms differentially activated between susceptible and resistance cherry varieties? Do susceptible and resistance cherry varieties present a differential priming under different PRIs exposure? Even more, the increasing of aridity and drought in the North of the country, the advancing desert toward the South and a reduction in water resources in the central zone of Chile, are expected along the XXI century. In this scenario of climate change, other question arises: Which are the molecular and physiological mechanisms involved in priming and defense activation in cherry plants upon Pss infection combined with water deficit? Through this proposal, we intend to answer to these questions, in order to establish the basis for optimize the control of the bacterial canker in cherry fruit tree, by strategies that provide for the use of resistance inductors. We propose two hypotheses: a) Cherry cultivars with differential susceptibility to bacterial canker, caused by Pseudomonas syringae pv. syringae, present genetic differences in the molecular machinery of plant immunity; b) Pseudomonas syringae pv. syringae infection is enhanced by water restriction due to an alteration of the molecular machinery of plant immunity. The aims of this proposal is to obtain a better understanding of the plant-pathogen molecular interactions of sweet cherry bacterial canker in relationship with water deficit, using mainly omics strategies.

[vc_section el_class="container mx-auto align-items-center circle--pattern" css=".vc_custom_1648956589196{padding-top: 3rem !important;}"][vc_row el_class="pb-5"][vc_column][vc_wp_custommenu nav_menu="6"][uoh_breadcrumb_component automatic_breadcrumb="true"][uoh_title_component title_dropdown="big" title_decorator="true"]{{title}}[/uoh_title_component][vc_column_text css=""]Soils constitute the largest terrestrial organic carbon (C) pool, which is three times the amount of CO2 currently in the atmosphere and several times the current annual fossil fuel emissions. Thus, increasing net soil C storage can represent a substantial C sink potential with the concomitant effect in the reduction of greenhouse gas (GHG) emissions under climate change scenario. Soils in central areas of Chile showed very low organic C levels as consequence of an intensive activity of different industries such as agriculture and mining. In this sense, the high incorporation of agrochemicals in conventional and intensive agriculture and the inadequate disposal of wastes in mining operations can negatively impact the different natural and agro-ecosystems, with detrimental effects on the soil ranging from erosion, loss of organic matter (OM) and C, and a large accumulation of trace elements, which ultimately results in a significant decrease in the quality of this resource. A significant increase in the accumulation of a wide range of heavy metals in the soil, including copper, lead, cadmium and zinc among others have been widely described and associated to mining and agricultural industries. On the other hand, under the context of sustainable agriculture, the use of agricultural wastes and thus the recycling of nutrients through biotechnological strategies is receiving increasing attention. Globally, the annual production of agricultural residues is approximately 3.7 Pg of dry matter. Straw, roots, stems and other tissues of corn, wheat and rice, are the main annual crop residues, which represent approximately 40.6%, 24.2% and 15.7%, respectively, of world production. Moreover, according to the literature, approximately 3.8 billion tons of livestock (pig and cow) and poultry manure is produced annually. For the sustainable management of these residues, aerobic composting has served as technological approach to transform this organic material into soil amendments used to increase C stock and improve different physical, chemical and biological properties of soil. However, some type of composts is degraded relatively fast under field conditions producing important nutrient losses and GHG emissions among others. The utilization of clay minerals and recalcitrant C sources as pyrogenic C (biochar) produced by pyrolysis, have gained increasing interest as additives of composting operations, due to their influence in the reduction of GHG emissions and their effectivity in the stabilization of C both in compost and soils, leading to a cleaner compost production (reduced in emissions and leaching) and potentially C sequestrant amendments. In our previous research we reported an increase in the stabilization of C during the composting of beef manure and wheat straw mixtures and the potential sequestration of C once end-products were applied to grassland soil by the effect of halloysite (nanoclay) and oat-based biochar applied as additives. Therefore, and taking into account the positive effect related to the utilization of these additives in the composting mixture, to know how the composting process of pig manure-slurry (which is highly in heavy metal contents and GHG and odors emissions) and corn stubble can be affected by the utilization of these additives (e.g., biochar and halloysite nanoclay) in the stability of the final product has not been studied yet and result as an interesting topic of research. Moreover, the influence of additives in GHG emissions, odors, C stabilization, metal availability and the main physico chemical and biological properties during the process of composting of these organic material mixtures is also not known. Furthermore, to understand how the incorporation of this additives can also contribute in the accumulation of C and potential C sequestration once end-products are applied to metal polluted soils, and how the produced amendments affects the metal availability in soil also needs to be elucidate. Hence, this proposal suggests as main objectives 1.- To study the influence of oat based-biochar and halloysite nanoclay as additives in the composting of pig manure-slurry/corn stubble and 2.- To evaluate the effects of the end-products from composting process in the restoration of metal polluted soils from mining and agricultural industries. In a first stage, a composting study using agricultural waste co-composted with biochar and nanoclays will be conducted wherein C stabilization and gas emissions will be analyzed. Then, in order to determine the decomposition and the environmental impacts of compost in soils such as nutrient leaching and gas emissions, the produced compost will be mixed with soil and incubated. Finally, with the aim to analyze the impacts of compost in metal availability in heavy metal polluted soil, a mesocosm experiment under greenhouse conditions, and field trials will be conducted. For a better understanding of C stabilization, GHG emission, heavy metal availability and the potential mechanisms associated to the process, analytical techniques such as stable C isotope ratios (δ13C), CPMAS13CNMR spectroscopy and ICP-OES spectroscopy will be used in collaboration with the Instituto de Recursos Naturales y Agrobiología de Sevilla, Spain (IRNAS-CSIC) and ICA-CSIC Madrid. It expects that the use of described additives will improve the composting of pig manure-slurry mixture producing amendments able to be efficiently used in the remediation of contaminated soils by increasing the preservation of C and reducing the availability of heavy metals minimizing its environmental impacts and losses[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Permanecer en cuarentena implica mantenerse en un lugar, a veces aislado de otras personas, con exposición a información negativa en los medios y con alta incertidumbre respecto a su duración. Existen varias consecuencias negativas en la salud mental de las personas producto de las medidas de cuarentena (Brooks y cols., 2020; Iasevoli y cols., 2020). Por ejemplo, la gente que ha pasado por cuarentenas demuestra síntomas de trastornos de ansiedad y depresión; así mismo, algunas condiciones como la duración de la cuarentena incrementan la prevalencia de síntomas (Hawryluck y cols., 2004). Además, las noticias e información sobre la cuarentena son un factor de estrés que pueden aumentar los niveles de ansiedad de la población (Brooks y cols., 2020). Considerando estos efectos, es relevante examinar si el confinamiento y las noticias de la pandemia afectan la ansiedad y el rendimiento en tareas de aprendizaje.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]

Las situaciones realistas generalmente involucran a ambos, lo que lleva a procesos de interacción complejos que son difíciles de separar y desenredar. En esta propuesta nos enfocamos en estudiar experimentalmente cómo la presencia de estructuras coherentes, tales como vórtices o singularidades, afectan las propiedades de las ondas superficiales en un régimen turbulento. Para ello, construiremos dos montajes experimentales para poder estudiar de forma sistemática las propiedades estadísticas de las ondas cuando interactúan con las estructuras mencionadas. Ambos sistemas tienen la ventaja de que, ajustando los parámetros de forzamiento, podemos controlar la aparición e intensidad de las estructuras. Por lo tanto, un estudio sistemático de su influencia en turbulencia de ondas (WT) es sencillo. La naturaleza intermitente del campo de ondas, así como los mecanismos detrás de la ruptura del espectro de WT en presencia de estas estructuras son algunas de las preguntas que pretendemos responder. Para abordar estas preguntas, proponemos realizar mediciones espaciotemporales, como la fotografía de luz difusa (DLP) y la velocimetría de imagen de partículas (PIV). Los resultados que surjan de esta investigación podrían ser de gran importancia para una teoría que, si bien es válida en muchos sistemas, aún está incompleta. Las aplicaciones de los resultados a otros sistemas, como los flujos geofísicos, también podrían ser posibles y bastante relevantes para una amplia comunidad.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]
