Au moment où nos sociétés contemporaines s'interrogent avec passion sur le statut de l'animal et sur la responsabilité éthique des êtres humains envers la création et l'environnement - jusqu'à la question des OGM -, cette étude est d'une brûlante actualité. Qu'en est-il de la notion de dignité de la créature, ancrée dans la Constituton fédérale? Est-elle, comme le prétendent certains, une coquille vide, un mot magique et creux, sans signification réelle? Quelle pourrait être sa portée pour les animaux prétendus inférieurs et pour les plantes? Les auteurs s'appuient sur la distinction entre dignité et valeur. Ils pennent leurs distances par rapport aux catégories d'anthropocentrisme, de pathocentrisme et et de biocentrisme, catégories conditionnant la plupart des théories éthiques au sujet de l'animal et de l'environnement. Il en résulte une nouvelle conception de la relation anthropologique en ^tre l'être humain, l'animal et la nature. La perspective de l'anthropo-relationalité sert de fondement à une approche respectueuse des animaux et des plantes, tout en reconnaissant la place et la responsabilité spécifiques de l'être humain et des sociétés démocratiques.

Thank you Chairman I would like to extend a warm welcome to our keynote speakers, David Byrne of the European Commission, Derek Yach from the World Health Organisation, and Paul Quinn representing Congressman Marty Meehan who sends his apologies. When we include the speakers who will address later sessions, this is, undoubtedly, one of the strongest teams that have been assembled on tobacco control in Europe. The very strength of the team underlines what I see as a shift – a very necessary shift – in the way we perceive the tobacco issue. For the last twenty years, we have lived out a paradox. It isn´t a social side issue. I make no apology for the bluntness of what I´m saying, and will come back, a little later, to the radicalism I believe we need to bring – nationally – to this issue. For starters, though, I want to lay it on the line that what we´re talking about is an epidemic as deadly as any suffered by human kind throughout the centuries. Slower than some of those epidemics in its lethal action, perhaps. But an epidemic, nonetheless. According to the World Health Organisation tobacco accounted for just over 3 million annual deaths in 1990, rising to 4.023 million annual deaths in 1998. The numbers of deaths due to tobacco will rise to 8.4 million in 2020 and reach roughly 10 million annually by 2030. This is quite simply ghastly. Tobacco kills. It kills in many different ways. It kills increasing numbers of women. It does its damage directly and indirectly. For children, much of the damage comes from smoking by adults where children live, study, play and work. The very least we should be able to offer every child is breathable air. Air that doesn´t do them damage. We´re now seeing a global public health response to the tobacco epidemic. The Tobacco Free Initiative launched by the World Health Organisation was matched by significant tobacco control initiatives throughout the world. During this conference we will hear about the experiences our speakers had in driving these initiatives. This Tobacco Free Initiative poses unique challenges to our legal frameworks at both national and international levels; in particular it raises challenges about the legal context in which tobacco products are traded and asks questions about the impact of commercial speech especially on children, and the extent of the limitations that should be imposed on it. Politicians, supported by economists and lawyers as well as the medical profession, must continue to explore and develop this context to find innovative ways to wrap public health considerations around the trade in tobacco products – very tightly. We also have the right to demand a totally new paradigm from the tobacco industry. Bluntly, the tobacco industry plays the PR game at its cynical worst. The industry sells its products without regard to the harm these products cause. At the same time, to gain social acceptance, it gives donations, endowments and patronage to high profile events and people. Not good enough. This model of behaviour is no longer acceptable in a modern society. We need one where the industry integrates social responsibility and accountability into its day-to-day activities. We have waited for this change in behaviour from the tobacco industry for many decades. Unfortunately the documents disclosed during litigation in the USA and from other sources make very depressing reading; it is clear from them that any trust society placed in the tobacco industry in the past to address the health problems associated with its products was misplaced. This industry appears to lack the necessary leadership to guide it towards just and responsible action. Instead, it chooses evasion, deception and at times illegal activity to protect its profits at any price and to avoid its responsibilities to society and its customers. It has engaged in elaborate ´spin´ to generate political tolerance, scientific uncertainty and public acceptance of its products. Legislators must act now. I see no reason why the global community should continue to wait. Effective legal controls must be laid on this errant industry. We should also keep these controls under review at regular intervals and if they are failing to achieve the desired outcomes we should be prepared to amend them. In Ireland, as Minister for Health and Children, I launched a comprehensive tobacco control policy entitled “Towards a Tobacco Free Society“. OTT?Excessive?Unrealistic? On the contrary – I believe it to be imperative and inevitable. I honestly hold that, given the range of fatal diseases caused by tobacco use we have little alternative but to pursue the clear objective of creating a tobacco free society. Aiming at a tobacco free society means ensuring public and political opinion are properly informed. It requires help to be given to smokers to break the addiction. It demands that people are protected against environmental tobacco smoke and children are protected from any inducement to experiment with this product. Over the past year we have implemented a number of measures which will support these objectives; we have established an independent Office of Tobacco Control, we have introduced free nicotine replacement therapy for low-income earners, we have extended our existing prohibitions on tobacco advertising to the print media with some minor derogations for international publications. We have raised the legal age at which a person can be sold tobacco products to eighteen years. We have invested substantially more funds in health promotion activities and we have mounted sustained information campaigns. We have engaged in sponsorship arrangements, which are new and innovative for public bodies. I have provided health boards with additional resources to let them mount a sustained inspection and enforcement service. Health boards will engage new Directors of Tobacco Control responsible for coordinating each health board´s response and for liasing with the Tobacco Control Agency I set up earlier this year. Most recently, I have published a comprehensive Bill – The Public Health (Tobacco) Bill, 2001. This Bill will, among other things, end all forms of product display and in-store advertising and will require all retailers to register with the new Tobacco Control Agency. Ten packs of cigarettes will be banned and transparent and independent testing procedures of tobacco products will be introduced. Enforcement officers will be given all the necessary powers to ensure there is full compliance with the law. On smoking in public places we will extend the existing areas covered and it is proposed that I, as Minister for Health and Children, will have the powers to introduce further prohibitions in public places such as pubs and the work place. I will also provide for the establishment of a Tobacco Free Council to advise and assist on an ongoing basis. I believe the measures already introduced and those additional ones proposed in the Bill have widespread community support. In fact, you´re going to hear a detailed presentation from the MRBI which will amply illustrate the extent of this support. The great thing is that the support comes from smokers and non-smokers alike. Bottom line, Ladies and Gentlemen, is that we are at a watershed. As a society (if you´ll allow me to play with a popular phrase) we´ve realised it´s time to ´wake up and smell the cigarettes.´ Smell them. See them for what they are. And get real about destroying their hold on our people. The MRBI survey makes it clear that the single strongest weapon we have when it comes to preventing the habit among young people is price. Simple as that. Price. Up to now, the fear of inflation has been a real impediment to increasing taxes on tobacco. It sounds a serious, logical argument. Until you take it out and look at it a little more closely. Weigh it, as it were, in two hands. I believe – and I believe this with a great passion – that we must take cigarettes out of the equation we use when awarding wage increases. I am calling on IBEC and ICTU, on employers and trade unions alike, to move away from any kind of tolerance of a trade that is killing our citizens. At one point in industrial history, cigarettes were a staple of the workingman´s life. So it was legitimate to include them in the ´basket´ of goods that goes to make up the Consumer Price Index. It isn´t legitimate to include them any more. Today, I´m saying that society collectively must take the step to remove cigarettes from the basket of normality, from the list of elements which constitute necessary consumer spending. I´m saying: “We can no longer delude ourselves. We must exclude cigarettes from the considerations we address in central wage bargaining. We must price cigarettes out of the reach of the children those cigarettes will kill.” Right now, in the monthly Central Statistics Office reports on consumer spending, the figures include cigarettes. But – right down at the bottom of the page – there´s another figure. Calculated without including cigarettes. I believe that if we continue to use the first figure as our constant measure, it will be an indictment of us as legislators, as advocates for working people, as public health professionals. If, on the other hand, we move to the use of the second figure, we will be sending out a message of startling clarity to the nation. We will be saying “We don´t count an addictive, killer drug as part of normal consumer spending.” Taking cigarettes out of the basket used to determine the Consumer Price Index will take away the inflation argument. It will not be easy, in its implications for the social partners. But it is morally inescapable. We must do it. Because it will help us stop the killer that is tobacco. If we can do it, we will give so much extra strength to health educators and the new Tobacco Control Association. This new organisation of young people who already have branches in over fifteen counties, is represented here today. The young adults who make up its membership are well placed to advise children of the dangers of tobacco addiction in a way that older generations cannot. It would strengthen their hand if cigarettes move – in price terms – out of the easy reach of our children Finally, I would like to commend so many public health advocates who have shown professional and indeed personal courage in their commitment to this critical public health issue down through the years. We need you to continue to challenge and confront this grave public health problem and to repudiate the questionable science of the tobacco industry. The Research Institute for a Tobacco Free Society represents a new and dynamic form of partnership between government and civil society. It will provide an effective platform to engage and mobilise the many different professional and academic skills necessary to guide and challenge us. I wish the conference every success.

Backgrounds and Aims The spatial separation of stigmas and anthers (herkogamy) in flowering plants functions to reduce self-pollination and avoid interference between pollen dispersal and receipt. Little is known about the evolutionary relationships among the three main forms of herkogamy - approach, reverse and reciprocal herkogamy (distyly) - or about transitions to and from a non-herkogamous condition. This problem was examined in Exochaenium (Gentianaceae), a genus of African herbs that exhibits considerable variation in floral morphology, including the three forms of herkogamy. Methods Using maximum parsimony and maximum likelihood methods, the evolutionary history of herkogamic and non-herkogamic conditions was reconstructed from a molecular phylogeny of 15 species of Exochaenium and four outgroup taxa, based on three chloroplast regions, the nuclear ribosomal internal transcribed spacer (ITS1 and 2) and the 5·8S gene. Ancestral character states were determined and the reconstructions were used to evaluate competing models for the origin of reciprocal herkogamy. Key results Reciprocal herkogamy originated once in Exochaenium from an ancestor with approach herkogamy. Reverse herkogamy and the non-herkogamic condition homostyly were derived from heterostyly. Distylous species possessed pendent, slightly zygomorphic flowers, and the single transition to reverse herkogamy was associated with the hawkmoth pollination syndrome. Reductions in flower size characterized three of four independent transitions from reciprocal herkogamy to homostyly. Conclusions The results support Lloyd and Webb's model in which distyly originated from an ancestor with approach herkogamy. They also demonstrate the lability of sex organ deployment and implicate pollinators, or their absence, as playing an important role in driving transitions among herkogamic and non-herkogamic conditions.

The concept of anti-inflammation is currently evolving with the definition of several endogenous inhibitory circuits that are important in the control of the host inflammatory response. Here we focus on one of these pathways, the annexin 1 (ANXA1) system. Originally identified as a 37 kDa glucocorticoid-inducible protein, ANXA1 has emerged over the last decade as an important endogenous modulator of inflammation. We review the pharmacological effects of ANXA1 on cell types involved in inflammation, from blood-borne leukocytes to resident cells. This review reveals that there is scope for more research, since most of the studies have so far focused on the effects of the protein and its peptido-mimetics on neutrophil recruitment and activation. However, many other cells central to inflammation, e.g. endothelial cells or mast cells, also express ANXA1: it is foreseen that a better definition of the role(s) of the endogenous protein in these cells will open the way to further pharmacological studies. We propose that a more systematic analysis of ANXA1 physio-pharmacology in cells involved in the host inflammatory reaction could aid in the design of novel anti-inflammatory therapeutics based on this endogenous mediator.

(Résumé de l'ouvrage) " Le livre de Raymond Brown sur la mort du Messie est un chef-d'eouvre monumental de l'exégèse historique. Il fait le point de la recherche historicocritique appliquée à la Passion de Jésus et en magnifie les résultats. Dans ce livre se dépose plus d'un siècle de critique textuelle, d'interrogation philologique, de comparaison littéraire, de vérification historique - un siècle d'enquêtes minutieuses, attachées à sonder les récits évangéliques sur la souffrance et la mort de Jésus le Nazôréen. La visée de cette somme exégétique est très clairement énoncée par l'auteur : "Expliquer en détail ce que les évangélistes ont voulu dire et ont transmis à leur auditoire par leurs récits de la Passion et de la mort de Jésus." (...) Les questions qui guident l'enquête sont aussi bien littéraires qu'historiques et théologiques. Quel regard les évangélistes posent-ils sur cette tragédie? Leurs récits sont-ils historiquement plausibles? D'où proviennent leurs informations? Que sait-on des pratiques judiciaires et religieuses de ce temps-la? Comment démêler les faits de l'interprétation dont ils sont enrobés? Peut-on recosntruire le scénario des événements? ". Daniel Marguerat

Screening for undernutrition among hospitalized children requires a systematic assessment of dietary intake. The development of a new tool for quick and playful assessment of dietary intake, called "Fleur" ("Flower"), at the Hôpital de l'Enfance in Lausanne allows to identify children at risk of undernutrition and to adapt their nutrition to their specific needs.

BACKGROUND The randomized placebo-controlled IFIGENIA-trial demonstrated that therapy with high-dose N-acetylcysteine (NAC) given for one year, added to prednisone and azathioprine, significantly ameliorates (i.e. slows down) disease progression in terms of vital capacity (VC) (+9%) and diffusing capacity (DLco) (+24%) in idiopathic pulmonary fibrosis (IPF). To better understand the clinical implications of these findings we performed additional, explorative analyses of the IFGENIA data set. METHODS We analysed effects of NAC on VC, DLco, a composite physiologic index (CPI), and mortality in the 155 study-patients. RESULTS In trial completers the functional indices did not change significantly with NAC, whereas most indices deteriorated with placebo; in non-completers the majority of indices worsened but decline was generally less pronounced in most indices with NAC than with placebo. Most categorical analyses of VC, DLco and CPI also showed favourable changes with NAC. The effects of NAC on VC, DLco and CPI were significantly better if the baseline CPI was 50 points or lower. CONCLUSION This descriptive analysis confirms and extends the favourable effects of NAC on lung function in IPF and emphasizes the usefulness of VC, DLco, and the CPI for the evaluation of a therapeutic effect. Most importantly, less progressed disease as indicated by a CPI of 50 points or lower at baseline was more responsive to therapy in this study.

Globularia alypum és un arbust termòfil típic de la regió oest del Mediterrani. Aquest nanofaneròfit té un patró de floració molt ampli. Les poblacions primerenques floreixen des del Juliol fins al Desembre i les poblacions tardanes des del Gener fins a l’Abril. L’objectiu del projecte és esbrinar quins factors climàtics determinen la fenologia de la floració de l’espècie a partir de mostres d’herbari i conèixer l’abast geogràfic d’ambdós patrons de floració a la península Ibèrica i França. També l’estudi d’altres característiques fenològiques en relació amb el clima: els braquiblasts i les espigues de capítols. Els plecs d’herbari han estat georeferenciats per ser utilitzats en un entorn SIG junt amb les dades del clima i s’ha realitzat una anàlisi estadística. El resultats mostren que les poblacions primerenques creixen majoritàriament en zones costaneres mentre que les tardanes ho fan en zones continentals. Les poblacions primerenques creixen en àrees on les temperatures (mitjana, mínima, màxima i mínima del mes més fred) són més altes que les tardanes per l’efecte temperador del mar. Al analitzar totes les poblacions, el nombre de mesos des de la transició floral es correlaciona negativament amb la temperatura mínima mensual i la temperatura mitjana mensual en tots els mesos, mentre que amb la temperatura màxima mensual entre Octubre i Abril. Al estudiar sols les poblacions tardanes les correlacions són similars, però no en les primerenques on no se’n troba cap. Les correlacions entre el nombre de mesos des de la transició floral i les variables climàtiques anuals són iguals, a més de trobar-se una correlació negativa amb la temperatura mínima del mes més fred i l’índex tèrmic, i positiva amb l’índex de continentalitat. No s’ha trobat cap diferència en presència de braquiblasts segons la població, però sí en les espigues de capítols, essent més freqüents en les poblacions primerenques. Es suggereix que la temperatura és un factor més determinant per a les poblacions tardanes, mentre que es desconeix si és la precipitació en les primerenques. Tampoc es té coneixement sobre si les diferències entre els dos patrons són genètiques o fenotípiques i quin mecanisme possibilita el desenvolupament de braquiblasts i espigues de capítols.

Résumé de la thèseBien que le mutualisme puisse être considéré comme une relation harmonieuse entre différentes espèces, son étude révèle plutôt une exploitation réciproque où chaque partenaire tente de maximiser ses bénéfices tout en réduisant ses coûts. Dans ce contexte, l'identification des facteurs qui favorisent ou contrarient, au cours de l'évolution, une issue mutualiste est une étape majeure pour pouvoir reconstruire les étapes clés menant à l'apparition et au maintien des interactions mutualistes. Le but de ce doctorat était l'identification des traits phénotypiques qui permettent à la plante Silene latofolia (Caryophyllacée)et à son pollinisateur - prédateur de graines, la phalène Hadena bicruris (Noctuidé), d'augmenter les bénéfices nets que chacun retire de l'interaction. Ce système d'étude est particulièrement bien approprié à l'étude de ces traits, car on peut assez facilement estimer la qualité et la quantité des descendants (fitness) des deux partenaires. En effet, la femelle papillon pond un oeuf dans la fleur qu'elle pollinise et sa larve se développe dans le fruit, consommant les graines de la plante. Ainsi, sur une même plante, il est possible d'estimer les succès respectifs de la plante et du papillon à obtenir une descendance. De plus, le conflit d'intérêt autour des graines qui sont indispensables, à la fois à la plante et au papillon, peut stimuler l'évolution de traits qui limitent la surexploitation réciproque des partenaires. Dans une première étude, j'ai montré que le papillon mâle était un pollinisateur efficace de S. latifolia et qu'ainsi, il permettait à la plante d'augmenter le nombre de graines produites (i.e.bénéfice) sans pour autant augmenter la quantité de larves sur la plante. Dans ce système, les papillons pondent un seul oeuf par fleur, déposé soit à l'intérieur de la fleur, dans le tube de corolle, soit sur le pétale. Ma seconde étude montre que les plantes répondent différemment à la présence des oeufs suivant leur position. Aussi, quand l'oeuf est placé dans la fleur, la plante a davantage tendance à ne pas développer le fruit de la fleur infesté ou bien à produire des fruits plus petits que lorsque l'oeuf est placé sur le pétale. Enfin, j'ai montré que la femelle du papillon pond plus souvent sur le pétale lorsque elle visite des fleurs dotées d'un long tube de corolle, et que les larves issues de ces oeufs ont moins de chances de réussir à pénétrer dans le fruit que les larves issues des oeufs placés à l'intérieur de la fleur. Aussi, la variation observée du site de ponte pourrait être causé par la morphologie de la fleur qui contraint le papillon à pondre sur le pétale. Vu dans leur ensemble, les résultats obtenus pendant ce doctorat suggèrent que la participation des mâles à la pollination, l'absence de développement des fruits et la profondeur du tube de corolle pourraient réduire les coûts que S. latifolia subit dans son interaction avec H. bicruris. Par ailleurs, je n'ai pas détecté de mécanismes qui permettraient au papillon de réduire les coûts que la plante pourrait lui imposer. La prochaine étape serait de déterminer l'effet des traits identifiés dans ce doctorat sur la fitness globale de la plante et du papillon pour estimer pleinement leur efficacité à réduire les coûts et à favoriser une issue mutualiste. De même, il faudrait évaluer l'effet de ces traits en populations naturelles pour identifier le rôle des facteurs environnementaux sur leur efficacité.AbstractAlthough mutualisms can be regarded as harmonious relationships between the interacting partners, they are best conceptualized as reciprocal exploitations in which each partner attempts to increase its own benefits and decrease its costs. To date, identifying the factors which promote or discourage mutualistic outcomes remains a major goal to reconstruct the ecological conditions leading to mutualisms. The aim of this PhD thesis was to identify phenotypic traits that may increase the net benefits of each partner in the interaction between the plant Silene latifolia (Caryophyllaceae) and its pollinator / seed predator, the moth Hadena bicruris (Noctuidae). This study system is particularly well suited because the fitness of both interacting species can be assessed. The female moth lays its egg in the flower it pollinated, and its offspring grows in the fruit, feeding on the seeds of the plant, which allows for the follow-up of both larva and fruit fates. Furthermore, the inherent conflict of interest over the seeds as plant progeny vs. larval resource may stimulate the evolution of traits that reduce overexploitation in both the moth and plant. In a first study, I show that male moths are efficient pollinators, hence increasing seed production without increasing oviposition. The contribution of male moths to pollination might thus improve the net benefits of the interaction for the host plant. Females of the H. bicruris moth lay a single egg per flower, and place it either inside the corolla tube or on the petal. My second study shows that plants are more likely to abort the infested flower or to produce a smaller fruit when the egg was experimentally placed inside the flower compared to plants that received an egg on the petal. Finally, female moths were found to lay their eggs more frequently on the petal when visiting a flower with a deep corolla tube, and larvae hatching from these eggs less likely to successfully attack the fruit. Variation in egg position on the flower may thus be the result of a constraint imposed by floral morphology. Overall, this PhD work suggests that the pollination by male moths, flower abortion, and deep corolla tube may efficiently reduce the costs experienced by S. latifolia in its interaction with H. bicruris. Interestingly, no apparent mechanism of costs reduction was detected for the moth. Further studies should focus on the effects of these traits (i) in the long term fitness of both the plant and the insect and (ii) their interactions with environmental factors (biotic and abiotic) that may affect their efficiency in natural populations.

L'article veut montrer à quel point le cinéma est d'abord une fiction de mots pour Blaise Cendrars, qui fut pourtant assistant d'Abel Gance, figurant, scénariste et même réalisateur. Le cinéma fut une passion, un art nouveau perçu comme LE révélateur de l'âme humaine. Aucun film ne subsiste parmi les archives, alors que les projets rédigés sont nombreux.
