Questionner le tourisme rural, c’est se poser la question des particularités de celui-ci notamment liées à sa dispersion, à ses difficultés d’organisation en une « destination », à ses représentations idylliques, à ce patrimoine plus ou moins commun, plus ou moins privatisé, que le touriste consomme, aux difficiles questions du partage des revenus du développement touristique, aux problèmes des équipements et surtout de l’accessibilité par transports individuels et collectifs de ces zones excentrées. Autour de quelques collègues soucieux de partager leur enthousiasme pour la recherche, nous avons convié des doctorants à partager dans le cadre d’une journée de l’école doctoral thématique en géographie auprès du Fonds National de la Recherche Scientifique, leurs interrogations et leurs premières investigations. Ce numéro thématique rassemble les principales contributions à cette réflexion commune, en proposant une étude de l'utilisation de l’autoroute pour développer des produits touristiques à proximité d’un flux important de personnes (Malet, 21-35), une analyse de la mise en tourisme d'un produit de terroir et de la manière d'en faire une ressource clé du tourisme régional (De Myttenaere, 37-51), une recherche sur les images et représentations d'une destination rurale et leur utilisation pour développer l’accueil et la promotion (Mazuel et Bonniot, 7-19), une enquête sur le rôle des associations intercommunales et des municipalités dans le développement des entreprises touristiques en milieu rural (Vanneste et Ryckaert 53-71), une réflexion sur la complexité des polémiques autour des loisirs motorisés (Haye et Mounet, 73-84) et enfin une lecture critique de textbooks anglais qui permet de constater le chemin fait et le chemin qui reste à faire pour réellement passer des monographies à des théories du tourisme sensibles aux particularités du milieu rural (Dubois, 85-94).

Listeria monocytogenes can proliferate at the beginning of cheesemaking as the conditions favor growth. The objective of this study was to establish the growth limits of L. monocytogenes in a cheese matrix, in case of potential contamination of the milk prior to cheese manufacture. A semisoft laboratory scale model cheese system was made at different initial pH and water activity (a(w)) levels with a mix of two strains of L. monocytogenes. A factorial design of five pH values (5.6 to 6.5), four a(w) values (0.938 to 0.96), and two L. monocytogenes inoculation levels (1 to 20 CFU/ml and 500 to 1,000 CFU/ml) was carried out. Each combination was evaluated in six independent replicates. In order to determine if there was a dominant strain, isolated colonies from the cheeses were analyzed by pulsed-field gel electrophoresis. The data relating to growth initiation were fitted to a logistic regression model. The a(w) of milk influenced the probability of growth initiation of L. monocytogenes at both low and high contamination levels. The pH, at the concentrations tested, had a lower effect on the probability of growth initiation. At pH 6.5 and a(w) of 0.99 for low contamination levels and pH 6.5 and a(w) of 0.97 for high contamination levels, increases in population of up to 4 and 2 log were observed at low and high contamination levels, respectively. This shows that if conditions are favorable for growth initiation at the early stages of the cheesemaking process, contamination of milk, even with low numbers, could lead to L. monocytogenes populations that exceed the European Union's microbiological limit of 100 CFU/g of cheese.

In this study, a new method has been developed to produce pure crystalline BaZrO3 powders from Ba+Zr solution or weakly soluble reactants by using precipitation route in highly basic aqueous solution. The influence of several synthesis parameters is studied. At high OH- concentration ([NaOH] = 20 mol/l), it is possible to obtain the well-crystallized stoichiometric perovskite phase at relatively low temperature (~80°C), after a short reaction time (15 minutes) and without requiring any precaution to avoid the presence of CO2. This synthesis method yields spherical particles, whose size can be controlled by changing the concentration of the Ba+Zr solution. No calcination treatment is necessary since the precipitate is crystalline. Suitable choice of the synthesis parameters ([NaOH] = 20 mol/l, [Ba+Zr] = 1 mol/l, reaction time = 15 minutes) yields a sub-micron precipitate. [less ▲]

463 lichen taxa are reported from the island of Reunion (Mascarene archipelago) in the Indian Ocean. This report is based on extensive collections recently made by the authors or hosted in B and LG. A total of c. 600 species is estimated for the number of lichenized fungi present on the island; although this is a low figure for a varied tropi- cal area, this is plausible due to its small size and remoteness. The significance of the lichen diversity of the island lays in its endemics, which need further study for a reliable assessment, and in the occurrence of a poorly known southern hemisphere element (“austral” species). The discovery of the following in Reunion is of special interest as it considerably enlarges their distribution range: Anzia corallophora, Caloplaca caesiosorediata, Coccocarpia delicatula, Fuscopannaria praetermissa, Gomphillus morchelloides, G. pedersenii, Gyalideopsis bispora, Heterodermia koyana, Hypotrachyna evansii, Lithogyalideopsis zeylandica, Lobaria asperula, Megaloblastenia marginiflexa var. dimota, Menegazzia capitata, Myeloconis erumpens and Pannaria squamulosa.

Six variants of human lysozyme (single-point mutations I56T, F57I, W64R, D67H and double mutations F57I/T70N, W112R/T70N) are associated with a hereditary non-neuropathic systemic amyloidose. These ... [more ▼]

Six variants of human lysozyme (single-point mutations I56T, F57I, W64R, D67H and double mutations F57I/T70N, W112R/T70N) are associated with a hereditary non-neuropathic systemic amyloidose. These proteins form extracellular amyloid fibrils that deposit in a wide range of tissues and organs such as liver, spleen and kidneys where they cause damages [1]. It was shown that the D67H and I56T mutations cause a loss in stability and more particularly a loss of global cooperativity of protein [1]. Consequently, under physiologically relevant conditions, these variants can transiently populate a partially unfolded state in which the beta-domain and the C-helix are cooperatively unfolded while the rest of the protein remains native like [1]. The formation of intermolecular interactions between the regions that are unfolded in this intermediate state is likely to be a fundamental trigger of the aggregation process that ultimately leads to the formation and deposition of fibrils in tissues. We have also shown that the binding of three variable domain of camelid antibodies or (VHHs) - raised against the wild type human lysozyme inhibit in vitro the formation of amyloid fibrils by the lysozyme variants. These three VHHs bind on different regions of lysozyme and act as amyloid fibrils inhibitor through different mechanisms [2, 3, and unpublished results]. In the present work, sixteen new VHHs specific of human lysozyme have been generated. Competition experiments have shown that they bind to five non overlapping epitopes. We have demonstrated that five of these new VHHs are able to bind lysozyme in conditions used for amyloid fibril formation, and interestingly two of them recognize two epitopes that are different from those of the three VHHs previously characterized [2, 3, and unpublished results]. The effects of these new VHHs on the properties of lysozyme variants such as activity, stability, cooperativity and aggregation will be discussed. [less ▲]
