The importance of myeloperoxidase in apocynin-mediated NADPH oxidase inhibition

Apocynin is widely used as an inhibitor of the NADPH oxidase. Since myeloperoxidase (MPO) has been considered as essential for the mechanism of action of apocynin, here we used cells with different levels of MPO and compared their sensitivity to apocynin. HL-60 cells were differentiated with DMSO or IFN γ /TNF α and compared with peripheral mononuclear (PBMC) and polymorphonuclear cells (PMN). The relative MPO activity was PBMC = HL60 DMSO < HL60 IFN γ < PMN. Apocynin inhibited the intracellular reactive oxygen species production by PMN (80%) and IFN γ /TNF α -differentiated HL-60 cells (45%) but showed a minor effect in PBMC and DMSO differentiated HL-60 cells (20%). The addition of azide decreased the efficiency of apocynin in PMN and the addition of peroxidase increased the inhibition in PBMC. We also determined the gene expression of the components gp91phox, p47phox, p22phox and p67phox in the resting cells. Apocynin did not change gp91phox, p47phox or p22phox gene expression in nonstimulated PBMC, HL60 DMSO, HL60 IFN γ /TNF α , and PMN and has a subtle increase in p67phox in HL60 IFN γ /TNF α . The results from this work suggest that a rational search for better inhibitors of NADPH oxidase in leukocytes should include a correlation with their affinity as substrates for MPO.

Promoting ethical and environmental awareness in vulnerable communities: a research action plan

Urban populations that live in the outskirts of major Latin American cities usually face conditions of vulnerability attached to complex environmental issues, such as the lack of sewerage, floods, pollution and soil and water contamination. This article reports an intervention research programme in Sao Paulo, Brazil that combines a moral education approach with sustainability awareness in vulnerable communities. The main conceptual foundations of the project, designed to empower the community and promote ethical and environmental awareness are: strengthening the ties between the school and the surrounding community in order to construct 'moral atmosphere'; adoption of Problem- and Project-based Learning and the Design Thinking approach to reach the proposed goals.

Crafting strategy : embodied metaphors in practice

The rationalist approach to strategizing emphasizes analytical and convergent thinking. Without denying the importance of this approach, this book argues that strategists must learn to complement it with a more creative approach to strategizing that emphasizes synthetic and divergent ways of thinking. The theoretical underpinnings of this approach include embodied realism, interpretivism, practice theory, theory of play, design thinking, as well as discursive approaches such as metaphorical analysis, narrative analysis, dialogical analysis and hermeneutics. The book includes in-depth discussions of these theories and shows how they can be put into practice by presenting detailed analyses of embodied metaphors built by groups of agents with step-by-step explanations of how this process can be implemented and facilitated. The link between theory and practice is further supported by the inclusion of several vignettes that describe how this approach has been successfully employed in a number of organizations, including BASF and UNICEF

Modelado experimental de un sistema de e-Salud aplicado en cooperación al desarrollo

Los Objetivos de Desarrollo del Milenio comprometieron a los países con una nueva alianza mundial de alcanzar gradualmente una cobertura universal de los niveles mínimos de bienestar en los países en desarrollo (reducir la pobreza y el hambre y dar respuesta a problemas como la mala salud, las desigualdades de género, la falta de educación, el acceso a agua salubre y la degradación ambiental). Para dar continuidad a esta iniciativa, recientemente en septiembre de 2015, la ONU promulgó la declaración de los Objetivos de Desarrollo Sostenible. Los ODM sitúan la salud en el corazón del desarrollo y establecen un novedoso pacto mundial que vincula a los países desarrollados y los países en desarrollo por medio de obligaciones claras y recíprocas. En este sentido, diversos organismos de cooperación a través de sus programas de cooperación internacional, tratan de mejorar el acceso a la asistencia sanitaria, especialmente a la población vulnerable que vive en zonas rurales de países en desarrollo. Con el fin de ayudar a cumplir los ODM que apoyan los temas de salud en dicha población, estos organismos desarrollan proyectos que despliegan sistemas de e-salud. Las intervenciones se enfrentan a múltiples retos: condicionantes de los países en desarrollo, las necesidades y demandas de los sistemas sanitarios y la complejidad de implantar las TIC en entornos complejos y altamente dinámicos como son los países en desarrollo. Estos condicionantes ocasionan la mayoría de proyectos fallidos que terminan convirtiéndose en soluciones aisladas, que anteponen la tecnología a las necesidades de la población y no generan el impacto esperado en su desarrollo. En este contexto tuvo origen esta tesis doctoral, que persigue como objetivo analizar, planificar, diseñar, verificar y validar un marco arquitectónico de implantación de sistemas de e-salud en áreas rurales de países en desarrollo, que promueva el mejoramiento de la calidad de vida de la población vulnerable de estas regiones y la efectividad de las intervenciones de e-salud en el marco de proyectos de cooperación al desarrollo. Para lograrlo, tomé como punto de partida, diversas estrategias, modelos, metodologías de implantación de e-salud, modelos de gestión de proyectos propuestos por distintos organismos internacionales y propuse una instanciación de estos modelos a proyectos de implantación de sistemas de e-salud en países en desarrollo. Apliqué la metodología action research y los enfoques twin track, middle out y design thinking que me permitieron el refinamiento iterativo del modelo propuesto en la tesis doctoral mediante el trabajo de campo realizado en dos zonas rurales de países de Centroamérica: Jocotán (Guatemala) y San José de Cusmapa (Nicaragua). Como resultado obtuve un modelo experimental basado en cuatro componentes: un modelo de referencia tipo, un modelo conceptual de e-salud, los procesos de gestión y de implantación de sistemas de e-salud en países en desarrollo y una arquitectura de referencia. El modelo experimental resultante aporta herramientas importantes para el despliegue de sistemas de e-salud en países en desarrollo. Se ha propuesto un modelo de referencia que proporciona una visión holística del contexto del país en desarrollo donde se desarrollarán las intervenciones. Un modelo conceptual de e-salud que representa los principales conceptos involucrados en un sistema de e-salud. Los procesos ii- de gestión del proyecto y de implantación del sistema que proporcionan a los grupos de cooperación, herramientas para el análisis, diseño, desarrollo y despliegue de los sistemas de e-salud en áreas rurales de países en desarrollo. Y finalmente la arquitectura de referencia que sienta las bases para la aplicación de estos procesos a un contexto en particular. Las líneas futuras de trabajo sugieren extender el modelo a más casos de estudio que permitan su refinamiento y evaluar los futuros usos que pueden surgir de los sistemas de e-salud resultantes. ABSTRACT Millennium Development Goals (MDGs) committing the countries with a new global partnership to achieve universal coverage of minimum levels of well-being in Developing Countries (for addressing extreme poverty in its many dimensions-income poverty, hunger, disease, lack of adequate housing, and exclusion-while promoting gender equality, education, and environmental sustainability). From September 2015, these goals are replaces with Sustainable Development Goals (SDGs). The MDG place health at the heart of development and establish a novel global compact, linking developed and developing countries through clear, reciprocal obligations. Many public and private institutions promote international cooperation programs to support in achieving the MDGs. Some of these cooperation programs deal improving access to healthcare to poor people living in isolated areas from developing countries. In order to accomplish this goal organizations perform projects (interventions or cooperation projects) that deploy e-health systems in these zones. Nevertheless, this kind of projects face multiple challenges that dismiss the effectiveness of the projects results. In particular, cooperation teams face issues such as constraints in developing countries, lack of electrical and ICT infrastructure, scarce transport, extreme climate conditions, lack ICT capacity, lack of access to healthcare and inefficient delivery methods, etc. Hence, these issues increase the complexity of implementing e-health in developing countries and then causes the most projects fail. In other words, the solutions do not meet population needs and do not generate the expected impact on development. This context is the starting point of this doctoral thesis, which deals with analysing, planning, designing, testing and validating an architectural framework in order to implement e-health systems in rural areas from developing countries, promote development of the population in these regions, and thus improve the impact of interventions of development cooperation projects. To achieve this goal, I took as a starting point the strategies, models, e-health implementation methodologies and projects management models proposed by various international agencies. Then I proposed an instantiation of these models to manage the intervention and implement e-health systems in developing countries. I applied the action research methodology and the approaches twin track, middle out and design thinking which allowed me the iterative refinement of the model proposed in this doctoral thesis. The proposed framework was validated by running two cases studies in rural areas of Central America: Jocotán (Guatemala) and San José de Cusmapa (Nicaragua). As a result, I obtained an experimental model based on four components: a Type reference model, an e-health conceptual model, both process management and implementation e-health systems in developing countries and a reference architecture. The resulting experimental model provides important tools for the deployment of e-health systems in developing countries. The model become as reference model that provides a holistic view of the developing countries context where the interventions will be running. The conceptual model of e-health represents the main concepts involved into an e-health system. The project management and implementation processes of the iv- system provide to the cooperation teams with tools for analysing, designing, developing and deploying e-health systems in rural areas from developing countries. Finally, the reference architecture provides the basis for the implementation of these processes into a particular context. The future research suggest the extension the model to other cases studies in order to refine and evaluate the viability the model.

Ambientes tecno-pedagógicos para o desenvolvimento de competências transversais para a inovação em engenharia.

Muito se fala na crescente velocidade de inovações tecnológicas que se apresenta ao mundo e que vai se acelerando. Antes, gerações se passavam para termos uma evolução tecnológica. Hoje, uma mesma geração presencia vários saltos tecnológicos. Neste contexto de inovações frequentes, surge a preocupação sobre como formar um profissional responsável, ético e que consiga acompanhar e ser protagonista de tais mudanças. O trabalho desenvolvido nesta tese busca colaborar na discussão sobre a formação do engenheiro, com foco na engenharia elétrica e de computação, revisitando as definições de conceitos como educação em engenharia, aprendizagem ativa, inovação, Design Thinking e competências transversais, e definindo, como contribuição de pesquisa, os conceitos de tecno-pedagogia e ambientes tecno-pedagógicos, como pressuposto de convergência de estruturas tecnológicas, estratégias pedagógicas e métodos de avaliação em aprendizagem ativa para a inovação. Apresenta um método para identificar e quantificar o grau de ênfase das competências transversais para a inovação a partir da demanda de mercado para engenheiros eletricistas e da computação; e um método de observação, coleta e análise de dados sobre o desenvolvimento de competências transversais na participação em duas experiências de aula: na disciplina global ME310 da Universidade de Stanford; e na disciplina 030-3410 da Escola Politécnica da Universidade de São Paulo. Com isso, foi possível elaborar um método para auxiliar no planejamento de disciplinas e cursos com foco em inovação, identificando as competências transversais que devem ser incentivadas e relacionando tais competências com estratégias de ensino e aprendizagem e sugerindo a estrutura tecnológica e método de avaliação a serem adotados.

Seguridad alimentaria, nutrición y erradicación del hambre CELAC 2025: elementos para el debate y la cooperación regionales

La región de América Latina y el Caribe ha mostrado una trayectoria exitosa en el proceso de erradicación del hambre y es la única región del mundo que redujo a la mitad tanto la proporción de personas que padecen hambre (meta establecida en los Objetivos de Desarrollo del Milenio) como el número absoluto de personas afectadas por el hambre (meta establecida en la Cumbre Mundial sobre la Alimentación, de 1996). El propósito de esta publicación es suministrar a los países de la región información actualizada y oportuna sobre el estado de la seguridad alimentaria y nutricional, el papel que tienen distintas áreas como la agricultura, el comercio agroalimentario y la gestión de recursos naturales en la erradicación del hambre y la posibilidad de enfrentar con éxito la doble carga de la malnutrición, en un contexto en que los efectos del cambio climático pueden amenazar los avances observados hasta el momento en América Latina y el Caribe. El Plan para la Seguridad Alimentaria, Nutrición y Erradicación del Hambre de la CELAC 2025 es una herramienta trascendental para el logro de los Objetivos de Desarrollo Sostenible de la Agenda 2030 para el Desarrollo Sostenible y, por ello, alienta a los países de América Latina y el Caribe a redoblar los esfuerzos para identificar las áreas clave de política que permitan acelerar y consolidar el proceso de erradicación del hambre y hacer frente a la doble carga de la malnutrición en la región, donde el sobrepeso y la obesidad se suman cada vez más a ese flagelo.

DEVELOPMENT OF A MECHANISM AND PROCESS TO CONTINUOUSLY PRODUCE SPHERICAL, TORREFIED BIOMASS PELLETS

A recently developed novel biomass fuel pellet, the Q’ Pellet, offers significant improvements over conventional white pellets, with characteristics comparable to those of coal. The Q’ Pellet was initially created at bench scale using a proprietary die and punch design, in which the biomass was torrefied in-situ¬ and then compressed. To bring the benefits of the Q’ Pellet to a commercial level, it must be capable of being produced in a continuous process at a competitive cost. A prototype machine was previously constructed in a first effort to assess continuous processing of the Q’ Pellet. The prototype torrefied biomass in a separate, ex-situ reactor and transported it into a rotary compression stage. Upon evaluation, parts of the prototype were found to be unsuccessful and required a redesign of the material transport method as well as the compression mechanism. A process was developed in which material was torrefied ex-situ and extruded in a pre-compression stage. The extruded biomass overcame multiple handling issues that had been experienced with un-densified biomass, facilitating efficient material transport. Biomass was extruded directly into a novel re-designed pelletizing die, which incorporated a removable cap, ejection pin and a die spring to accommodate a repeatable continuous process. Although after several uses the die required manual intervention due to minor design and manufacturing quality limitations, the system clearly demonstrated the capability of producing the Q’ Pellet in a continuous process. Q’ Pellets produced by the pre-compression method and pelletized in the re-designed die had an average dry basis gross calorific value of 22.04 MJ/kg, pellet durability index of 99.86% and dried to 6.2% of its initial mass following 24 hours submerged in water. This compares well with literature results of 21.29 MJ/kg, 100% pellet durability index and <5% mass increase in a water submersion test. These results indicate that the methods developed herein are capable of producing Q’ Pellets in a continuous process with fuel properties competitive with coal.

McLean builds strong connections between the cultural capital of the Jerwood prizewinning craft maker and the world of business and trade. It is crucial that higher education research can consider its relationship to the creative industries. London is a fashion capital, known for its style experimentation and playful creativity. The wit and anarchic play of the art school is a leading force in fashion innovation and Mclean's work articulates this clearly. Designing hats that reference the stylised coiffures of Hollywood icons, in the soft medium of felted wool, is a sophisticated play on the relations between nature and culture that, according to Levi Straus, are at the heart of all culture. The Fifty Hats that Changed the World makes direct allusion to the way that fashion is often regarded with mild disdain as insignificant or trivial, and the Design Museum London, an international leader in disseminating design discourse has, recently, included fashion design within its agenda for exhibition. McLean's work is a leading component of this transformation of design culture.

Designing Creative Destruction

This research aims to make a contribution in the context of design thinking at a global cultural scale and specifically how design methods are a feature of the homogenising and heterogenising forces of globalisation via creative destruction. Since Schumpeter’s description of economic innovation destroying the old and creating the new, a number of other interpretations of creative destruction have developed including those driving cultural evolution. However a design model showing the impact of different types of design method on cultural evolution can develop an understanding on a more systemic level from the medium to longer term impact of new designs that homogenise or increase the differences between various cultures. This research explores the theoretical terrain between creative destruction, design thinking and cybernetics in the context of exchanging cultural influences for collaborative creativity and concludes with an experiment that proposes a feedback loop between ubiquitising and differentiating design methods mediating cultural variety in creative ecosystems.
