Community Education Needs to be Supported by Strong Public Policy to Tackle Food Poverty

Community education needs to be supported by strong public policy if it is to be fully effective at tackling food poverty and obesity, a project evaluation by the Institute of Public Health in Ireland (IPH) has found. In its evaluation of Decent Food for All (DFfA) - a major project to improve community diet and health - IPH found that where people live and shop had a greater impact on their diet than their own individual awareness and attitudes. Access Tackling Food Poverty: lessons from the Decent Food for All intervention at www.publichealth.ie DFfA was funded by safefood (the Food Safety Promotion Board) and the Food Standards Agency Northern Ireland. The project lasted four years and included hundreds of community education activities designed to improve diet in poorer parts of Armagh and South Tyrone. safefood commissioned IPH to undertake the evaluation of DFfA. Dr. Kevin Balanda, IPH Associate Director, said 'The aim of the project was to reduce food poverty (this is defined as not being able to consume adequate healthy food) and improve health in the target communities. DFfA delivered over 370 core activities to 3,100 residents including local education talks on diet, cookery workshops, fresh fruit in schools, healthy food tastings and information stands. One in eight residents in the target areas participated in at least one of these activities.' The evaluation found that over 1 in 5 adults in the target areas reported they had cut their weekly food spending in the last six months to pay other household bills such as rent, electricity and gas. During the four years of the DFfA activities, this percentage had not changed significantly. There were mixed changes in the nature of food in local stores. While the overall availability and price of food increased, both ﾓhealthierﾔ food and ﾓunhealthierﾔ food were included in that increase. It was only in the larger ﾓmultiple/discount freezerﾔ type of shops that the overall price of food had decreased.

The interaction of human pathogenic arena viruses with the host cell

SummaryResearch projects presented in this thesis aimed to investigate two major aspects of the arenaviruses life cycle in the host cell: viral entry and the biosynthesis of the viral envelope glycoprotein.Old World arenaviruses (OWAV), such as Lassa virus (LASV) and lymphocytic choriomeningitis virus (LCMV), attach to the cell by binding to their receptor, alpha-dystroglycan. Virions are then internalized by a largely unknown pathway of endocytosis and delivered to the late endosome/lysosome where fusion occurs at low pH. In the major project of my thesis, we sought to identify cellular factors involved in OWAV cell entry. Our work indicates that OWAV cell entry requires microtubular transport and a functional multivesicular body (MVB) compartment. Infection indeed depends on phosphatidyl inositol 3-kinase (PI3K) activity and lysobisphosphatidic acid (LBPA), a lipid found in membranes of intraluminal vesicles (ILVs) of the MVB. We further found a requirement of factors that are part of the endosomal sorting complex required for transport (ESCRT), involved in the formation of ILVs. This suggests an ESCRT-mediated sorting of virus- receptor complex during the entry process.During viral replication, biosynthesis of viral glycoprotein takes place in the endoplasmic reticulum (ER) of the host cell. When protein load exceeds the folding capacity of the ER, the accumulation of unfolded proteins is sensed by three ER resident proteins, activating transcription factor 6 (ATF6), inositol-requiring enzyme 1 (IRE1) and PKR-like ER kinase (PERK), whose signaling induces the cellular unfolded protein response (UPR). Our results indicate that acute LCMV infection transiently induces the activation of the ATF6 branch of the UPR, whereas the PERK, and IRE1 axis of UPR are neither triggered nor blocked during infection. Our data also demonstrate that activation of ATF6 pathway is required for optimal viral replication during acute infection.The formation of the mature, fusion-active form of arenaviruses glycoproteins requires proteolytic cleavage mediated by the cellular protease subtilisin kexin isozyme-1 (SKI-l)/site-l protease (SIP). We show that targeting the SKI-1/S1P enzymatic activity with specific inhibitors is a powerful strategy to block arenaviruses productive infection. Moreover, characterization of protease function highlights differences in processing between cellular and viral substrates, opening new possibilities in term of drug development against human pathogenic arenaviruses.RésuméLes projets de recherche présentés dans cette thèse visaient à étudier deux aspects du cycle de vie des arenavirus: l'entrée du virus dans la cellule hôte et la biosynthèse de la glycoprotéine durant la réplication virale.Les arenavirus du vieux monde (OWAV), tels que le virus de Lassa (LASV) et le virus de la chorioméningite lymphocytaire (LCMV) s'attachent à la cellule hôte en se liant à leur récepteur, l'alpha-dystroglycane. Les virions sont ensuite intemalisés par une voie d'endocytose inconnue et livrés à l'endosome tardif/lysosome, où le pH acide permet la fusion entre l'enveloppe virale et la membrane du compartiment. Le projet principal de ma thèse consistait à identifier les facteurs cellulaires impliqués dans l'entrée des OWAV dans la cellule hôte. Nos résultats indiquent que l'entrée des OWAV nécessite le transport microtubulaire et la présence d'un corps multivésiculaire (MVB) fonctionnel. L'infection dépend en effet de l'activité de phosphatidyl inositol 3-kinase (PI3K) et de lysobisphosphatidic acid (LBPA), un lipide présent dans les membranes des vésicules intraluminales (ILVs) du MVB. Nous avons également trouvé l'implication de facteurs constituant l'endosomal sorting complex required for sorting (ESCRT) qui joue un rôle dans la formation des ILVs. Ces donnés suggèrent l'incorporation du complexe virus-récepteur dans des ILVs durant le processus d'entrée.Lors de la réplication virale, la biosynthèse de la glycoprotéine virale a lieu dans le réticulum endoplasmique (ER) de la cellule hôte. Lorsque la charge de protéines nouvellement synthétisées excède la capacité de pliage des protéines dans le ER, l'accumulation de protéines mal pliées est détectée par trois facteurs: activating transcription factor 6 (ATF6), inositol-requiring enzyme 1 (IRE1) et PKR-like ER kinase (PERK). Leur signalisation constitue la réponse cellulaire face aux protéines mal pliées (UPR). Nos résultats montrent que l'infection aiguë avec LCMV induit transitoirement l'activation de la voie de signalisation ATF6 alors que les axes PERK et IRE1 de l'UPR ne sont ni induits ni bloqués pendant l'infection. Nos données prouvent également que l'activation de la voie ATF6 est nécessaire à une réplication virale optimale lors de l'infection aiguë avec LCMV.La maturation des glycoprotéines des arenavirus nécessite un clivage protéolytique par la protéase cellulaire subtilisin kexin isozyme-1 (SKI-l)/site-l protease (SIP). Nous avons démontré que le ciblage de l'activité enzymatique de SKI-1/SIΡ avec des inhibiteurs spécifiques est une stratégie prometteuse pour bloquer l'infection par les arenavirus. La caractérisation du mécanisme d'action de la protéase a, par ailleurs, révélé des différences au niveau du clivage entre les substrats cellulaires et viraux, ce qui ouvre de nouvelles perspectives en terme de développement de médicaments contre les arenavirus pathogènes pour l'homme.

Exploring unfrequent events with accelerated molecular dynamics simulations: from photochemistry to drug design

La meva incorporació al grup de recerca del Prof. McCammon (University of California San Diego) en qualitat d’investigador post doctoral amb una beca Beatriu de Pinós, va tenir lloc el passat 1 de desembre de 2010; on vaig dur a terme les meves tasques de recerca fins al darrer 1 d’abril de 2012. El Prof. McCammon és un referent mundial en l’aplicació de simulacions de dinàmica molecular (MD) en sistemes biològics d’interès humà. La contribució més important del Prof. McCammon en la simulació de sistemes biològics és el desenvolupament del mètode de dinàmiques moleculars accelerades (AMD). Les simulacions MD convencionals, les quals estan limitades a l’escala de temps del nanosegon (~10-9s), no son adients per l’estudi de sistemes biològics rellevants a escales de temps mes llargues (μs, ms...). AMD permet explorar fenòmens moleculars poc freqüents però que son clau per l’enteniment de molts sistemes biològics; fenòmens que no podrien ser observats d’un altre manera. Durant la meva estada a la “University of California San Diego”, vaig treballar en diferent aplicacions de les simulacions AMD, incloent fotoquímica i disseny de fàrmacs per ordinador. Concretament, primer vaig desenvolupar amb èxit una combinació dels mètodes AMD i simulacions Car-Parrinello per millorar l’exploració de camins de desactivació (interseccions còniques) en reaccions químiques fotoactivades. En segon lloc, vaig aplicar tècniques estadístiques (Replica Exchange) amb AMD en la descripció d’interaccions proteïna-lligand. Finalment, vaig dur a terme un estudi de disseny de fàrmacs per ordinador en la proteïna-G Rho (involucrada en el desenvolupament de càncer humà) combinant anàlisis estructurals i simulacions AMD. Els projectes en els quals he participat han estat publicats (o estan encara en procés de revisió) en diferents revistes científiques, i han estat presentats en diferents congressos internacionals. La memòria inclosa a continuació conté més detalls de cada projecte esmentat.

IDENTITÉ, PROJET, CHANGEMENT : DES REPRÉSENTATIONS SOCIALES AUX LEVIERS DE L'ACTION PUBLIQUE. POUR UN MODE DE GOUVERNANCE AXÉ SUR LE DÉVELOPPEMENT TERRITORIAL. ETUDE DE CAS : CANTON DU JURA (SUISSE)

Thirty years after the Canton of Jura entered sovereignty, it has to be admited that the creation of the newly canton did't fullfill the hopes of economic and demografic growth that many could have expected from political independance. Through a plurality of complementary approaches, the research suggest a closer look at, on one hand, the position of the Canton in its territorial context as well as its structure and dynamics and on the other hand, the representations of the territory and its evolution by the social actors. This in order to formulate a set of social demands (of debate, of openness and of overcoming cleavages) which augurs for a new territoriality regime and testify of a requirement of reflexivity toward the state institutions and actions. The analysis allowed to set in evidence the central role of the couple identity-project in the dynamics of change, and to identifiy three main periods in the recent past of the Canton: a period of territorialization, during which grew a strong collective identity, coupled with a major project of society (the creation of the canton of Jura); then followed a period of deterritorialization, with the fragmentation of the collective identity and the lack of a project of society. Then, the third period, with a paradoxical event, the failure in public vote of the the project Jura open Land (Jura Pays ouvert), which was meant to give a second wind to the Canton. We consider this turning point as the start of a new period (of reterritorialization), with an issue linked with the outlines of a renewed "jurassian" identity and the elaboration of a shared territory project.Trente ans après l'entrée en souveraineté, force est de constater que la création du canton du Jura n'a pas permis de répondre aux espérances de développement économique et démographique que l'indépendance politique devait entraîner dans son sillage. Cette recherche se propose, à travers une pluralité d'approches complémentaires, d'examiner d'une part la position du Canton dans son contexte territorial ainsi que sa structure et sa dynamique; d'autre part, les représentations que se font les acteurs du territoire et de son évolution, pour déboucher sur une série de demandes sociales (de débat, d'ouverture et de dépassement des clivages) qui augurent de la transition vers un nouveau régime de territorialité et témoignent d'une exigence de réflexivité envers les institutions et les actions de l'Etat. L'analyse a permis de mettre en évidence le rôle central du couple identité-projet dans la dynamique de changement et d'identifier trois temps forts dans l'évolution récente du Canton, une phase de territorialisation au cours de laquelle s'est constituée une identité forte doublée d'un projet de société majeur, suivie d'une phase de déterritorialisation avec une fragmentation de l'identité collective et l'absence de projet mobilisateur. Enfin, un moment paradoxal, l'échec du projet Jura Pays ouvert, censé redonner un second souffle au Canton, qui amorce une nouvelle étape (de reterritorialisation) avec un questionnement lié aux contours d'une identité jurassienne renouvelée et à l'élaboration d'un projet de territoire partagé.Les ressorts de la production du territoire et de son développement sont analysés à travers le rôle des représentations sociales dans la constitution identitaire et le projet territorial, à l'exemple du canton du Jura. La mise en évidence du rôle central du couple identité-projet dans la dynamique de changement a permis d'identifier trois temps forts dans l'évolution récente du Canton. Une première phase (la création du canton du Jura), au cours de laquelle s'est constituée une identité forte doublée d'un projet de société majeur, suivie d'une phase au cours de laquelle l'identité collective s'est fragmentée en l'absence de projet mobilisateur (la phase de « gestion » de l'Etat). Puis un moment de rupture (l'échec du projet Jura Pays ouvert) et l'amorce d'une transition vers une nouvelle étape, avec un questionnement lié aux contours d'une identité jurassienne renouvelée, à l'élaboration d'un projet de territoire partagé, et à l'action des pouvoirs publics dans un contexte de repositionnement du Canton.

Large scale assessment of regulatory evolution and transcriptome complexity in mammals

AbstractIn addition to genetic changes affecting the function of gene products, changes in gene expression have been suggested to underlie many or even most of the phenotypic differences among mammals. However, detailed gene expression comparisons were, until recently, restricted to closely related species, owing to technological limitations. Thus, we took advantage of the latest technologies (RNA-Seq) to generate extensive qualitative and quantitative transcriptome data for a unique collection of somatic and germline tissues from representatives of all major mammalian lineages (placental mammals, marsupials and monotremes) and birds, the evolutionary outgroup.In the first major project of my thesis, we performed global comparative analyses of gene expression levels based on these data. Our analyses provided fundamental insights into the dynamics of transcriptome change during mammalian evolution (e.g., the rate of expression change across species, tissues and chromosomes) and allowed the exploration of the functional relevance and phenotypic implications of transcription changes at a genome-wide scale (e.g., we identified numerous potentially selectively driven expression switches).In a second project of my thesis, which was also based on the unique transcriptome data generated in the context of the first project we focused on the evolution of alternative splicing in mammals. Alternative splicing contributes to transcriptome complexity by generating several transcript isoforms from a single gene, which can, thus, perform various functions. To complete the global comparative analysis of gene expression changes, we explored patterns of alternative splicing evolution. This work uncovered several general and unexpected patterns of alternative splicing evolution (e.g., we found that alternative splicing evolves extremely rapidly) as well as a large number of conserved alternative isoforms that may be crucial for the functioning of mammalian organs.Finally, the third and final project of my PhD consisted in analyzing in detail the unique functional and evolutionary properties of the testis by exploring the extent of its transcriptome complexity. This organ was previously shown to evolve rapidly both at the phenotypic and molecular level, apparently because of the specific pressures that act on this organ and are associated with its reproductive function. Moreover, my analyses of the amniote tissue transcriptome data described above, revealed strikingly widespread transcriptional activity of both functional and nonfunctional genomic elements in the testis compared to the other organs. To elucidate the cellular source and mechanisms underlying this promiscuous transcription in the testis, we generated deep coverage RNA-Seq data for all major testis cell types as well as epigenetic data (DNA and histone methylation) using the mouse as model system. The integration of these complete dataset revealed that meiotic and especially post-meiotic germ cells are the major contributors to the widespread functional and nonfunctional transcriptome complexity of the testis, and that this "promiscuous" spermatogenic transcription is resulting, at least partially, from an overall transcriptionally permissive chromatin state. We hypothesize that this particular open state of the chromatin results from the extensive chromatin remodeling that occurs during spermatogenesis which ultimately leads to the replacement of histones by protamines in the mature spermatozoa. Our results have important functional and evolutionary implications (e.g., regarding new gene birth and testicular gene expression evolution).Generally, these three large-scale projects of my thesis provide complete and massive datasets that constitute valuables resources for further functional and evolutionary analyses of mammalian genomes.

Roadway Design Standards for Rural and Suburban Subdivisions Final Report, June 2007

In Iowa, there are currently no uniform design standards for rural and suburban subdivision development roadways. Without uniform design standards, many counties are unable to provide adequate guidance for public facilities, particularly roadways, to be constructed as part of a rural subdivision development. If a developer is not required to install appropriate public improvements or does not do so properly, significant liability and maintenance expenses can be expected, along with the potential for major project costs to correct the situation. Not having uniform design standards for rural and suburban subdivision development improvements in Iowa creates situations where there is potential for inconsistency and confusion. Differences in the way development standards are applied also create incentives or disincentives for developers to initiate subdivision platting in a particular county. With the wide range of standards or lack of standards for local roads in development areas, it is critical that some level of uniformity is created to address equity in development across jurisdictional lines. The standards must be effective in addressing the problem, but they must not be so excessive as to curtail development activities within a local jurisdiction. In order to address the concerns, cities and counties have to work together to identify where growth is going to be focused. Within that long-term growth area, the roadways should be constructed to urban standards to provide an easier transition to traditional urban facilities as the area is developed. Developments outside of the designated growth area should utilize a rural cross section since it is less likely to have concentrated urban development. The developers should be required to develop roadways that are designed for a minimum life of 40 years, and the county should accept dedication of the roadway and be responsible for its maintenance.

09029-015 Otter Creek Watershed Final Report

The City of West Union has been selected by Iowa Department of Economic Development as a Green Pilot Community. A major project within this designation is the reconstruction of the downtown business district public infrastructure in a sustainable, innovative, and replicable way. A key component of this project is replacement of the impermeable street and sidewalk surfacing with a porous paver system. This system, along with bio-retention cells in intersection bumpouts and sidewalk planters, will infiltrate, then cleanse and cool the storm water prior to a very slow discharge rate to Otter Creek. The project area will see a 95% reduction in peak discharge rate for a 100 year storm and a 20% reduction in runoff volume. West Union is located within the Otter Creek watershed, a designated cold water trout stream just below the city. Fayette County Soil and Water Conservation District and IDNR consider improvement of the water quality of Otter Creek to be very important. This reconstruction of downtown West Union in a sustainable manner will be the start of an overall Otter Creek watershed improvement project.

Student projects: plagiarism and assessment

Within the Information Technology degree programme of the University of Reading, the students undertake a major project in their final year. The module is both a hurdle to an honours degree and significant in terms of assessment weighting. The two year history so far has shown that bad citation and plagiarism are issues, and in one case called for the due referral of a project report. In the light of experience to date, we are focusing firstly on plagiarism prevention, giving generic advice on report writing and citation practice, and secondly on detection. In the longer term, I believe we need to reflect on what capabilities we should be creating in our undergraduates and therefore what and how we should be assessing them.

Expert system to calculate the cofficient of friction : an approach to enhance traffic safety

Friction plays a key role in causing slipperiness as a low coefficient of friction on the road may result in slippery and hazardous conditions. Analyzing the strong relation between friction and accident risk on winter roads is a difficult task. Many weather forecasting organizations use a variety of standard and bespoke methods to predict the coefficient of friction on roads. This article proposes an approach to predict the extent of slipperiness by building and testing an expert system. It estimates the coefficient of friction on winter roads in the province of Dalarna, Sweden using the prevailing weather conditions as a basis. Weather data from the road weather information system, Sweden (RWIS) was used. The focus of the project was to use the expert system as a part of a major project in VITSA, within the domain of intelligent transport systems
