Early life host-microbe interactions : implications for the development of asthma

Plus de 300 millions de personnes dans le monde souffrent de l'asthme. L'asthme est une maladie inflammatoire chronique des voies respiratoires caractérisée par des symptômes variables et récurrents, une obstruction bronchique réversible et des bronchospasmes. Les symptômes communs incluent une respiration sifflante, de la toux, une oppression thoracique et de la dyspnée. Normalement, la maladie commence à se manifester pendant l'enfance. Pourtant, facteurs génétiques héréditaires et événements environnementaux survenant au cours de la petite enfance sont responsables de sa manifestation, indiquant que le développement de la maladie est lié à des événements qui se produisent bien avant son déclenchement. L'infection respiratoire virale aiguë constitue un de ces facteurs environnementaux jouant un rôle prépondérant. Un des virus les plus communs est le virus respiratoire syncytial (VRS), qui infecte presque tous les enfants avant l'âge de 2 ans. Ce virus, s'il infecte des tout-petits, peut en effet provoquer une bronchiolite aiguë, un phénomène qui a été épidémiologiquement lié à l'apparition d'asthme plus tard dans la vie. Dans le premier chapitre de cette thèse, nous avons étudié, chez la souris, comment une infection avec le VRS influe sur l'asthme allergique. Nous avons constaté que seule l'infection des souris à l'état de nouveau-né prédispose à un asthme allergique plus sévère chez l'adulte. En effet, si des souris adultes étaient infectées, elles étaient protégées contre l'apparition des symptômes asthmatiques. Cela nous a mené à investiguer les mécanismes immunitaires spécifiques durant cette courte période du début de la vie. Deux événements se produisent en parallèle au cours de la petite enfance: (1) Le système immunitaire, qui est encore immature immédiatement après la naissance, commence à se développer pour être en mesure de jouer son rôle protecteur contre les agents infectieux. (2) Le corps, y compris les poumons, est colonisé par des bactéries commensales, qui vivent en symbiose avec leur hôte humain. Chez l'adulte, ces bactéries sont connues pour influencer notre système immunitaire, l'éduquant à générer des réponses immunitaires adéquates et efficaces. Dans la deuxième partie de cette thèse, nous avons voulu déterminer si ces bactéries symbiotiques étaient impliquées dans l'éducation du système immunitaire du nouveau-né et quelles conséquences cela pourrait avoir sur les réponses immunitaires engendrées par ce dernier. Pour étudier l'effet de ces bactéries symbiotiques, nous avons utilisé des souris stériles, en d'autres termes des souris qui n'hébergent pas ces bactéries symbiotiques. En comparant ces souris stériles à des souris qui abritent une flore microbienne normale, nous avons constaté que les bactéries symbiotiques sont vitales pour la bonne éducation du système immunitaire du nouveau-né. Nous avons démontré que le contact direct des cellules immunitaires avec la flore microbienne dans les poumons modifie le phénotype de ces cellules immunitaires, ce qui change probablement leur réaction au cours de réponses immunitaires. Nous avons donc vérifié si l'éducation immunitaire induite par cette microflore est importante pour prévenir les maladies pulmonaires telles que l'asthme allergique, affections qui sont causées par une réaction excessive du système immunitaire envers des agents inoffensifs. En effet, nous avons observé que le processus de maturation du système immunitaire néonatal, lequel a été déclenché et façonné par la flore microbienne, est important pour éviter une réaction asthmatique exagérée chez la souris adulte. Ce phénomène est dû aux lymphocytes T régulateurs. Ces cellules, dont la présence est induite dans les poumons, ont des capacités immunosuppressives et atténuent donc les réponses immunitaires pour prévenir une inflammation excessive. En conclusion, nous avons montré dans cette thèse que la colonisation par des bactéries symbiotiques tôt dans la vie est un événement décisif pour la maturation du système immunitaire et pour prévenir le développement de l'asthme. Dans l'avenir, il serait intéressant de découvrir quelles bactéries sont présentes dans les poumons du nouveau-né et lesquelles sont directement impliquées dans ce processus de maturation immunitaire. Une prochaine étape serait alors de favoriser la présence de ces bactéries au début de la vie au moyen d'un traitement avec des agents pré- ou probiotiques, ce qui pourrait éventuellement contribuer à une prévention précoce du développement de l'asthme. -- L'asthme est une maladie chronique inflammatoire des voies respiratoires affectant près de 300 millions d'individus dans le monde. Bien que les traits caractéristiques du phénotype asthmatique s'établissent généralement pendant l'enfance, la prédisposition au développement de la maladie est intimement liée à des événements survenant durant la petite enfance, comme le sont par exemple les infections virales respiratoires aiguës. Les mécanismes par lesquels ces événements provoquent un dysfonctionnement immunitaire et, par conséquent, conduisent au développement de l'asthme n'ont pas encore été entièrement décelés. La dysbiose du microbiote des voies respiratoires a été récemment associes au phénotype asthmatique, touisTcis, la cuûoboiatioî! d un lien cause à effet entre la dysbiose microbienne et l'apparition des symptômes asthmatiques reste à être démontrée. Dans cette thèse, nous avons étudié le rôle que joue la colonisation microbienne des voies respiratoires au cours de la petite enfance dans la maturation du système immunitaire ainsi que dans la protection contre l'inflammation pulmonaire de type allergique. Nous avons de surcroît développé un modèle expérimental pour comprendre comment les infections virales respiratoires interfèrent avec ce processus. Dans la première partie de cette thèse, nous avons évalué l'effet d'infections causées par le virus respiratoire syncytial (VRS) sur le développement de l'asthme. En accord avec des études épidémiologiques, nous avons constaté qu'une infection au VRS lors de la période néonatale exacerbait les réponses pulmonaires allergiques ultérieures. Par contraste, une infection à l'âge adulte avait un effet protecteur. Nous avons ainsi démontré que l'influence d'une infection à VRS sur l'issue et la sévérité de l'asthme respiratoire était strictement dépendante de l'âge. Ces résultats nous ont conduit à émettre l'hypothèse que des différences dans le phénotype homéostatique des cellules immunitaires pourraient être responsables de ces disparités liées à l'âge. Par conséquent, dans la deuxième partie de cette thèse, nous avons suivi et caractérisé le processus de maturation des cellules immunitaires dans les poumons du nouveau-né en condition d'homéostasie. Nous avons découvert que leur phénotype change de façon dynamique pendant le développement néonatal et que la colonisation par des microbes était déterminante pour la maturation des cellules immunitaires dans les poumons. Dans la dernière partie de cette thèse, nous avons démontré comment le microbiote pulmonaire éduque le développement immunitaire durant la période néonatale l'orientant de manière à induire une tolérance face aux aéroallergènes. Nous avons découvert que la colonisation microbienne des voies respiratoires provoque une expression transitoire de PD-L1 sur les cellules dendritiques (CD) pulmonaires du type CD11b+ dans les deux premières semaines de la vie. Cet événement engendre par la suite la génération de lymphocytes T régulateurs (TREG) dans les poumons, lesquels sont responsables de la protection contre une réponse inflammatoire allergique exagérée chez la souris adulte. Par conséquent, nous proposons un rôle pivot de la maturation immunitaire induite par le microbiote pulmonaire dans l'établissement de la tolérance aux aéroallergènes. En conclusion, les résultats présentés dans cette thèse fournissent de nouveaux indices révélant comment des événements se produisant lors de la petite enfance peuvent façonner les réponses du système immunitaire dirigées contre les allergènes et soulignent le rôle central joué par le microbiote pulmonaire dans l'édification d'une réponse immunitaire équilibrée. En résumé, notre travail met en évidence le microbiote pulmonaire comme étant une cible potentielle pour la prévention de certaines maladies respiratoires. -- Asthma is a chronic inflammatory disorder of the respiratory tract and affects approximately 300 million individuals world-wide. Although the asthmatic phenotype commonly establishes during childhood, predisposition towards disease development has been linked to events in early infancy, such as severe respiratory viral infections. However, the mechanisms by which these events cause immune dysfunction and, therefore, lead to the development of asthma have yet to be fully deciphered. Dysbiosis of the airway microbiota has recently been associated with the asthmatic phenotype; however, conclusive evidence for a causal link between microbial dysbiosis in the ail ways and asthma development is still missing. In this thesis we investigated the role of early-life microbial airway colonization in immune maturation and the protection against allergic airway inflammation and established an experimental model to address how respiratory viral infections interfere in this process. In the first part of this thesis we evaluated the effect of Respiratory syncytial virus (RSV) infections on the development of asthma. In concurrence with epidemiological studies, we found that neonatal infection exacerbated subsequent allergic airway inflammation. In contrast, adult infection was protective in the same context. Thus, we could demonstrate that the influence of RSV infection on subsequent allergic airway responses was strictly age-dependent. These findings led us to the hypothesis that differences in the homeostatic phenotype of immune cells could be responsible for the age-related disparities seen within the context of RSV. Therefore, in a second part of this thesis, we followed the process of homeostatic immune cell maturation in the neonatal lung. Immune cell phenotypes changed dynamically during neonatal development. We discovered that the colonization with microbes was central to the maturation of immune cells in the lung. In the last part of this thesis, we demonstrated how microbiota-driven immune development during the neonatal period induces tolerance against aeroallergens. We discovered that microbial colonization led to a transient programmed death-ligand (PD-L) 1 expression on CD11b+ pulmonary dendritic cells (DCs) during the first two weeks of life. This in turn induced regulatory T (TREG) cells in the lung, which were responsible for the protection against exaggerated allergic airway inflammation in adult mice. Thus, we propose a key role for microbiota-driven immune maturation in the establishment of tolerance towards aeroallergens. In conclusion, the results presented in this thesis provide new insights into how early-life events shape pulmonary immune responses towards allergens and suggest the airway microbiota as a key player in establishing a balanced immune response. Overall, our work highlights the airway microbiota as potential target for disease prevention.

Development of Furnace Model for Bubbling Fluidized Bed Boiler

The aim of this thesis was to develop a model, which can predict heat transfer, heat release distribution and vertical temperature profile of gas phase in the furnace of a bubbling fluidized bed (BFB) boiler. The model is based on three separate model components that take care of heat transfer, heat release distribution and mass and energy balance calculations taking into account the boiler design and operating conditions. The model was successfully validated by solving the model parameters on the basis of commercial size BFB boiler test run information and by performing parametric studies with the model. Implementation of the developed model for the Foster Wheeler BFB design procedures will require model validation with existing BFB database and possibly more detailed measurements at the commercial size BFB boilers.

Customer driven business model – connecting customer value to firm resources in ICT value networks

The objective of this thesis is to provide a business model framework that connects customer value to firm resources and explains the change logic of the business model. Strategic supply management and especially dynamic value network management as its scope, the dissertation is based on basic economic theories, transaction cost economics and the resource-based view. The main research question is how the changing customer values should be taken into account when planning business in a networked environment. The main question is divided into questions that form the basic research problems for the separate case studies presented in the five Publications. This research adopts the case study strategy, and the constructive research approach within it. The material consists of data from several Delphi panels and expert workshops, software pilot documents, company financial statements and information on investor relations on the companies’ web sites. The cases used in this study are a mobile multi-player game value network, smart phone and “Skype mobile” services, the business models of AOL, eBay, Google, Amazon and a telecom operator, a virtual city portal business system and a multi-play offering. The main contribution of this dissertation is bridging the gap between firm resources and customer value. This has been done by theorizing the business model concept and connecting it to both the resource-based view and customer value. This thesis contributes to the resource-based view, which deals with customer value and firm resources needed to deliver the value but has a gap in explaining how the customer value changes should be connected to the changes in key resources. This dissertation also provides tools and processes for analyzing the customer value preferences of ICT services, constructing and analyzing business models and business concept innovation and conducting resource analysis.

Development of a population-based cost-effectiveness model of chronic graft versus host disease in Spain

Chronic graft-versus-host disease (cGvHD) is the leading cause of late nonrelapse mortality (transplant-related mortality) after hematopoietic stem cell transplant. Given that there are a wide range of treatment options for cGvHD, assessment of the associated costs and efficacy can help clinicians and health care providers allocate health care resources more efficiently. OBJECTIVE: The purpose of this study was to assess the cost-effectiveness of extracorporeal photopheresis (ECP) compared with rituximab (Rmb) and with imatinib (Imt) in patients with cGvHD at 5 years from the perspective of the Spanish National Health System. METHODS: The model assessed the incremental cost-effectiveness/utility ratio of ECP versus Rmb or Imt for 1000 hypothetical patients by using microsimulation cost-effectiveness techniques. Model probabilities were obtained from the literature. Treatment pathways and adverse events were evaluated taking clinical opinion and published reports into consideration. Local data on costs (2010 Euros) and health care resources utilization were validated by the clinical authors. Probabilistic sensitivity analyses were used to assess the robustness of the model. RESULTS: The greater efficacy of ECP resulted in a gain of 0.011 to 0.024 quality-adjusted life-year in the first year and 0.062 to 0.094 at year 5 compared with Rmb or Imt. The results showed that the higher acquisition cost of ECP versus Imt was compensated for at 9 months by greater efficacy; this higher cost was partially compensated for ( 517) by year 5 versus Rmb. After 9 months, ECP was dominant (cheaper and more effective) compared with Imt. The incremental cost-effectiveness ratio of ECP versus Rmb was 29,646 per life-year gained and 24,442 per quality-adjusted life-year gained at year 2.5. Probabilistic sensitivity analysis confirmed the results. The main study limitation was that to assess relative treatment effects, only small studies were available for indirect comparison. CONCLUSION: ECP as a third-line therapy for cGvHD is a more cost-effective strategy than Rmb or Imt.

An integrated model of adoption and development of e-commerce in companies

Since the mid-1990s researchers have sought to understand why some firms embark on e-commerceoperations on the Internet while others prefer to wait and see how events unfold. We still have todetermine which variables contribute to explaining the extent to which firms use e-commerce, giventhat to date the literature has not yet offered conclusive evidence on this question. The current workaims to provide an integrated vision of the set of factors influencing the e-commerce adoptionprocess. We use a sample of 2,038 firms of all types that trade their products either with otherorganizations or with end-consumers.

Commodity Price Driven Risk Management from Viewpoint of High Grade Steel Alloys

The study of price risk management concerning high grade steel alloys and their components was conducted. This study was focused in metal commodities, of which nickel, chrome and molybdenum were in a central role. Also possible hedging instruments and strategies for referred metals were studied. In the literature part main themes are price formation of Ni, Cr and Mo, the functioning of metal exchanges and main hedging instruments for metal commodities. This section also covers how micro and macro variables may affect metal prices from the viewpoint of short as well as longer time period. The experimental part consists of three sections. In the first part, multiple regression model with seven explanatory variables was constructed to describe price behavior of nickel. Results were compared after this with information created with comparable simple regression model. Additionally, long time mean price reversion of nickel was studied. In the second part, theoretical price of CF8M alloy was studied by using nickel, ferro-chrome and ferro-molybdenum as explanatory variables. In the last section, cross hedging possibilities for illiquid FeCr -metal was studied with five LME futures. Also this section covers new information concerning possible forthcoming molybdenum future contracts as well. The results of this study confirm, that linear regression models which are based on the assumption of market rationality, are not able to reliably describe price development of metals at issue. Models fulfilling assumptions for linear regression may though include useful information of statistical significant variables which have effect on metal prices. According to the experimental part, short futures were found to incorporate the most accurate information concerning the price movements in the future. However, not even 3M futures were able to predict turning point in the market before the faced slump. Cross hedging seemed to be very doubtful risk management strategy for illiquid metals, because correlations coefficients were found to be very sensitive for the chosen time span.

Comparison of a deterministic and a data driven model to describe MBR fouling

Membrane bioreactors (MBRs) are a combination of activated sludge bioreactors and membrane filtration, enabling high quality effluent with a small footprint. However, they can be beset by fouling, which causes an increase in transmembrane pressure (TMP). Modelling and simulation of changes in TMP could be useful to describe fouling through the identification of the most relevant operating conditions. Using experimental data from a MBR pilot plant operated for 462days, two different models were developed: a deterministic model using activated sludge model n°2d (ASM2d) for the biological component and a resistance in-series model for the filtration component as well as a data-driven model based on multivariable regressions. Once validated, these models were used to describe membrane fouling (as changes in TMP over time) under different operating conditions. The deterministic model performed better at higher temperatures (>20°C), constant operating conditions (DO set-point, membrane air-flow, pH and ORP), and high mixed liquor suspended solids (>6.9gL-1) and flux changes. At low pH (<7) or periods with higher pH changes, the data-driven model was more accurate. Changes in the DO set-point of the aerobic reactor that affected the TMP were also better described by the data-driven model. By combining the use of both models, a better description of fouling can be achieved under different operating conditions

Innovación y Aprendizaje: un nuevo modelo para la formación universitaria: ¿Por qué y para qué? = Innovation and Learning: a New Model for University Education: Why and for What?

The legislative reforms in university matters driven in recent years, beyond the provoked controversies, offer to universities the possibility to develop a new model in line with the European environment, focusing on quality aims and adapting to the socioeconomic current challenges. A new educational model centered on the student, on the formation of specific and transverse competitions, on the improvement of the employability and the access to the labor market, on the attraction and fixation of talent, is an indispensable condition for the effective social mobility and for the homogeneous development of a more responsible and sustainable socioeconomic and productive model

A Development and Application of a Three-Dimensional Model for a CFB Gasifier

The developing energy markets and rising energy system costs have sparked the need to find new forms of energy production and increase the self-sufficiency of energy production. One alternative is gasification, whose principles have been known for decades, but it is only recently when the technology has become a true alternative. However, in order to meet the requirements of modern energy production methods, it is necessary to study the phenomenon thoroughly. In order to understand the gasification process better and optimize it from the viewpoint of ecology and energy efficiency, it is necessary to develop effective and reliable modeling tools for gasifiers. The main aims of this work have been to understand gasification as a process and furthermore to develop an existing three-dimensional circulating fluidized bed modeling tool for modeling of gasification. The model is applied to two gasification processes of 12 and 50 MWth. The results of modeling and measurements have been compared and subsequently reviewed. The work was done in co-operation with Lappeenranta University of Technology and Foster Wheeler Energia Oy.

Customer Driven Service Development – Technology-based Care and Services for the Elderly

The objective of this master’s thesis was to examine technology-based smart home devices and services. Topic was approached through basic theories, transaction cost theory and resource-based view in order to build basis for this thesis. Conceptual framework was discussed by means of networks, value networks and service systems which provide a useful framework for service development. The needs of the elderly living at home were discussed in order to find out which technology-based services could be used to satisfy the needs. Segmentation and need data collected previously during proactive home visits was exploited and additionally a survey targeted to experts and professionals of social and health care sector was done to verify the needs. Finally, the results of the survey were analyzed using quality function deployment method to figure out the most important and suitable service offerings for the elderly. As a conclusion of analysis, social media and monitoring services are the most useful technology-based services. However, traditional home services will still maintain their necessity too.

Development of a weather-based model for Botrytis leaf blight of onion

ABSTRACT In the present study, onion plants were tested under controlled conditions for the development of a climate model based on the influence of temperature (10, 15, 20 and 25°C) and leaf wetness duration (6, 12, 24 and 48 hours) on the severity of Botrytis leaf blight of onion caused by Botrytis squamosa. The relative lesion density was influenced by temperature and leaf wetness duration (P <0.05). The disease was most severe at 20°C. Data were subjected to nonlinear regression analysis. Beta generalized function was used to adjust severity and temperature data, while a logistic function was chosen to represent the effect of leaf wetness on the severity of Botrytis leaf blight. The response surface obtained by the product of two functions was expressed as ES = 0.008192 * (((x-5)1.01089) * ((30-x)1.19052)) * (0.33859/(1+3.77989 * exp (-0.10923*y))), where ES represents the estimated severity value (0.1); x, the temperature (°C); and y, the leaf wetness (in hours). This climate model should be validated under field conditions to verify its use as a computational system for the forecasting of Botrytis leaf blight in onion.
