Desarrollo e interrupción de la generatividad en ámbitos familiares, comunitarios y políticos. Development and interruption of the generatividad in familiar, communitarian and political ambients.

El presente proyecto está centrado en tres crisis vitales del desarrollo humano: la identidad, la generatividad y la integridad del yo (Erikson, 1961). Se indagará la relación existente entre estos momentos del desarrollo psicosocial con las vicisitudes y crisis sociales y políticas que atraviesan el desarrollo personal. El sentido de lo político, la participación comunitaria y social se pondrán en tensión con la historia de acontecimientos que le sucedieron a las personas a lo largo de su vida y se plasman en las narrativas vitales.La tarea de actualizar las identificaciones tempranas, fundirse en un proyecto personal, de pareja, social y laboral implica la consolidación de la identidad y prepara a las personas para la etapa más fructífera de la adultez: la intimidad y la generatividad. Esta tarea implica involucrarse en la guía de otras generaciones más jóvenes a la vez que se sostiene el cuidado personal y el propio desarrollo y expansión del self.Sin embargo, existen dificultades en el desarrollo adulto que, sin conformarse en patologías, obturan la expresión de estos componentes egosintónicos y se manifiestan otros componentes egodistónicos o debilidades del yo. Asimismo, crisis sociales y eventos históricos significativos atraviesan la vida de las personas marcando sus metas de desarrollo y transformando el sentido de sí mismos y el significado de ser en el mundo con otros. Las expresiones personales y familiares de la generatividad tienen diferentes manifestaciones que se expresan en el campo social, comunitario y político y en el ejercicio de distintos roles sociales (voluntariado, participación política, inclusión en organizaciones comunitario, liderazgo de instituciones sociales, gremiales, partidarias o religiosas). En cualquier caso interesa conocer y determinar qué factores del desarrollo temprano y adulto establecen diferentes niveles de compromiso, interés e involucramiento. Los objetivos se centran en determinar los componentes de la generatividad y sus expresiones agénticas y comunitarias. Se utilizará un abordaje combinado de metodología cuantitativa y cualitativa. Se desarrollará una escala de generatividad aportando las evidencias de confiabilidad y validez requeridos en el desarrollo psicométrico. Posteriormente se administrará una entrevista pautada semidirigida, que permita valorar cualitativamente las diferencias centrales en las historias de vida entre sujetos con diferentes niveles de generatividad y grupos u organizaciones específicamente vinculadas al cuidado de los otros (derechos humanos, organizaciones comunitarias y ONG's vinculados al desarrollo infantil y cuidado de la vejez). De esta forma se valorará el impacto de crisis vitales y familiares, tanto como adversidades sociales y políticas (violencia, represión) en la generatividad, la madurez en adultez y la participación social y comunitaria.Se espera, así, identificar los aspectos egosintónicos comunes que son esenciales para desarrollar y consolidar fortalezas, secuencias de sentido, de redención y plenitud vital y compromiso político y comunitario a pesar de las adversidades en poblaciones diversas. La contrastación de las narrativas vitales permitirá elucidar qué potencialidades y recursos psicológico se ponen en juego, no sólo para la recuperación tras la adversidad (factores resilientes), sino para el desarrollo de una madurez comprometida con causas sociales y humanitarias que de forma reparatoria, restauran una porción de la realidad en la que se sufrió la injusticia y la crueldad, no ya para sí mismos sino para el resto de la sociedad.

Vacunación en la Enfermedad de Chagas experimental: estudio de mediadores involucrados en la protección en ratones y aplicación de la vacuna en perros. Vaccination in experimental Chagas'disease: study of intermediates involved in the protection of mice and application of the vaccine in dogs.

La Enfermedad de Chagas es una de las principales endemias de América Latina donde existen cerca de 18 millones de infectados y 90 millones en riesgo. Entre el 25 y el 30 por ciento desarrolla patología cardíaca o digestiva en el período crónico. Se ha postulado que mecanismos autoinmunes, sumados a la acción directa del parásito, podrían estar involucrados en la patogenia de la enfermedad. El desarrollo de vacunas tradicionales en Enfermedad de Chagas es una meta difícil de alcanzar, por lo cual parece más factible abordar estrategias basadas en la inmunomodulación, para disminuir la carga parasitaria, minimizar las acciones deletéreas en el periodo agudo y prevenir el desarrollo de patología en la etapa crónica. Para ello es necesario avanzar en el conocimiento de los mecanismos involucrados en la protección y en la patogenia. Si se acepta la hipótesis autoinmune, una estrategia de vacunación con un tripanosoma antigénicamente similar al T. cruzi pero no patógeno podría evitar posibles mecanismos autoagresivos. En nuestro Laboratorio se ha empleado un modelo de vacunación en ratones utilizando como inmunógeno el Trypanosoma rangeli, no patógeno en humanos. Los ratones vacunados, infectados con T. cruzi, mostraron buena respuesta inmune celular y humoral, bajas parasitemias, ausencia de lesiones histológicas, y sobrevida cercana al 100 por ciento. Los controles no vacunados tuvieron una elevada mortalidad. Debido al ciclo biológico del parásito, la defensa efectiva contra el T. cruzi requiere una potente respuesta de anticuerpos contra las formas extracelulares y una eficaz respuesta celular contra los amastigotes intracelulares. En el modelo desarrollado en nuestro laboratorio la protección se asocia con un adecuado equilibrio entre respuesta TH1 y TH2, con leve predominio TH1, disminución de citoquinas (Ck) proinflamatorias e incremento de receptores solubles de Ck. El esquema de inmunización demostró asimismo su eficacia en cobayos y en perros mantenidos en el Laboratorio. Hipótesis de trabajo: - La vacunación con T. rangeli desencadena mecanismos inmunomodulatorios que protegen de la infección con T. cruzi, entre los cuales se encuentran eventos que actúan tempranamente en el sitio de inoculación y en los que están involucradas células y moléculas del sistema inmune innato. - La vacunación a perros constituye una nueva herramienta en la lucha contra la Enfermedad de Chagas. Objetivos: i) profundizar el estudio tendiente a dilucidar los mecanismos involucrados en la resistencia inducida por la inmunización con T. rangeli en ratones; ii) estudiar el efecto que tiene el estrés físico de los ratones sobre la eficacia de la vacunación y iii) analizar la inmunogenicidad de la vacuna en perros de zonas endémicas para Enfermedad de Chagas. Material y metodos: Los ratones y perros serán vacunados con tres dosis de epimastigotes de T. rangeli, fijados con glutaraldehido y los controles solo recibirán PBS. Los ratones seran desafiados con T. cruzi. Se estudiará en liquido peritoneal: a) poblaciones celulares por Citometria de flujo; b) cuantificación de los distintos tipos de inmunoglobulinas, de citoquinas y sus receptores solubles, por ELISA, c) ON y arginasa, por técnicas colorimetricas; d) est.udio de la interacción macrófago-parásito y de receptores celulares por Inmunofluorescencia. e) En perros, se realizarán estudios parasitológicos (xenodiagnostico) y serológicos en vacunados y controles, 12 y 24 meses post vacunación. Resultados esperados e importancia del proyecto: se espera conocer los principales eventos tempranos que participan en la eliminación de los parásitos en los animales vacunados, el efecto del stress sobre la vacunación y asimismo, la inmunogenicidad de la vacuna en perros de campo. Todo ello permitirá obtener información sobre la eficacia de la vacunación experimental y podría aportar una herramienta adicional contra la Enfermedad de Chagas, interfiriendo en la cadena epidemiológica en áreas endémicas.

The design and development of heat extraction technologies for the utilisation of compost thermal energy

A composting Heat Extraction Unit (HEU) was designed to utilise waste heat from decaying organic matter for a variety of heating application The aim was to construct an insulated small scale, sealed, organic matter filled container. In this vessel a process fluid within embedded pipes would absorb thermal energy from the hot compost and transport it to an external heat exchanger. Experiments were conducted on the constituent parts and the final design comprised of a 2046 litre container insulated with polyurethane foam and kingspan with two arrays of qualpex piping embedded in the compost to extract heat. The thermal energy was used in horticultural trials by heating polytunnels using a radiator system during a winter/spring period. The compost derived energy was compared with conventional and renewable energy in the form of an electric fan heater and solar panel. The compost derived energy was able to raise polytunnel temperatures to 2-3°C above the control, with the solar panel contributing no thermal energy during the winter trial and the electric heater the most efficient maintaining temperature at its preset temperature of 10°C. Plants that were cultivated as performance indicators showed no significant difference in growth rates between the heat sources. A follow on experiment conducted using special growing mats for distributing compost thermal energy directly under the plants (Radish, Cabbage, Spinach and Lettuce) displayed more successful growth patterns than those in the control. The compost HEU was also used for more traditional space heating and hot water heating applications. A test space was successfully heated over two trials with varying insulation levels. Maximum internal temperature increases of 7°C and 13°C were recorded for building U-values of 1.6 and 0.53 W/m2K respectively using the HEU. The HEU successfully heated a 60 litre hot water cylinder for 32 days with maximum water temperature increases of 36.5°C recorded. Total energy recovered from the 435 Kg of compost within the HEU during the polytunnel growth trial was 76 kWh which is 3 kWh/day for the 25 days when the HEU was activated. With a mean coefficient of performance level of 6.8 calculated for the HEU the technology is energy efficient. Therefore the compost HEU developed here could be a useful renewable energy technology particularly for small scale rural dwellers and growers with access to significant quantities of organic matter

The endodermis--development and differentiation of the plant's inner skin.

Controlling external compound entrance is essential for plant survival. To set up an efficient and selective sorting of nutrients, free diffusion via the apoplast in vascular plants is blocked at the level of the endodermis. Although we have learned a lot about endodermal specification in the last years, information regarding its differentiation is still very limited. A differentiated endodermal cell can be defined by the presence of the "Casparian strip" (CS), a cell wall modification described first by Robert Caspary in 1865. While the anatomical description of CS in many vascular plants has been very detailed, we still lack molecular information about the establishment of the Casparian strips and their actual function in roots. The recent isolation of a novel protein family, the CASPs, that localizes precisely to a domain of the plasma membrane underneath the CS represents an excellent point of entry to explore CS function and formation. In addition, it has been shown that the endodermis contains transporters that are localized to either the central (stele-facing) or peripheral (soil-facing) plasma membranes. These features suggest that the endodermis functions as a polar plant epithelium.

Development and growth of the early juveniles of the spider crab Maja squinado (Brachyura: Majoidea) in an individual culture system

The spider crab Maja squinado is an endangered Mediterranean species; therefore, culturing it successfully is essential for developing restocking programs. The survival, growth and development of post-larval stages (juvenile crabs, C1-C8) were studied using larvae obtained from adult individuals collected in the Catalan Sea. The juvenile crab stages were cultured individually from a megalopal stage using a semi-open recirculation system to obtain the precise growth data of each juvenile crab stage until C8. Development up to C8 at 20ºC lasted 154±10 days. Survival from C1 to C8 was 5.8 %. Moult increment values in cephothoracic length were similar in all the crab stages (21-35 %). Intermoult duration (9±1 in C1-C2 to 51±8 days in C7-C8) increased sharply from juvenile stage 5. Males and females can be distinguished from C4 based on sexual dimorphism in the pleopods and the presence of gonopores. The allometric growth of the pleon is sex-dependent from C4, with females showing positive allometry and males isometric growth. The juvenile growth rate was lower compared with that of the previously studied Atlantic species Maja brachydactyla.

IPH Submission to Department of the Environment, Heritage and Local Government Climate Change Response Bill 2010

The main purpose of the Clmate Change Bill is to provide for the adoption of a national policy for reducing greenhouse gas (GHG) emissions; to support this through the making of mitigation and adaptation action plans; and to make provision for emission reduction targets to support the objective of transition to a low carbon, climate resilient and environmentally sustainable economy.The remit of the Institute of Public Health in Ireland (IPH) is to promote cooperation for public health between Northern Ireland and the Republic of Ireland in the areas of research and information, capacity building and policy advice. Our approach is to support Departments of Health and their agencies in both jurisdictions, and maximise the benefits of all-island cooperation to achieve practical benefits for people in Northern Ireland and the Republic of Ireland.IPH has a keen interest in the effects of climate change on health. In September 2010 the IPH published a paper – Climate Change and Health: A platform for action - to inform policy-makers and the public about the health benefits in reducing greenhouse gas emissions. This paper followed a seminar with international speakers, opened by Minister Gormley, on the same topic in February 2010.

Effect of Temperature on the Development and Survival of the Argentine Ant, Linepithema humile

The influence of temperature on the developmental times and survival of insects can largely determine their distribution. For invasive species, like the Argentine ant, Linepithema humile Mayr (Hymenoptera: Formicidae), these data are essential for predicting their potential range based on mechanistic models. In the case of this species, such data are too scarce and incomplete to make accurate predictions based on its physiological needs. This research provides comprehensive new data about brood survival and developmental times at a wide range of temperatures under laboratory conditions. Temperature affected both the complete brood development from egg to adult worker and each of the immature stages separately. The higher the temperature, the shorter the development times. Brood survival from egg to adult was low, with the maximum survival rate being only 16% at 26º C. Temperature also affected survival of each of the immature stages differently: eggs were negatively affected by high temperatures, while larvae were negatively affected by low temperatures, and the survival of pupae was apparentlyindependent of environmental temperature. At 32º C no eggs survived, while at 18º C less than 2% of the eggs hatched into larva. The data from the present study are essential for developing prediction models about the distribution range of this tramp species based on its physiological needs in relation to temperature
