The aims of this study were to characterise a model of feline allergic airway inflammation and to test through a longitudinal investigation whether five repeated allergen exposures would lead to signs of airway remodelling that would be detectable in vivo. Eight healthy control cats and eight cats sensitised with Ascaris suum allergens were investigated. Barometric whole body plethysmography (BWBP) was used for the assessment of respiratory variables and airway responsiveness (AR). Bronchoalveolar lavage fluid (BALF) was sampled for cytology and determination of F-2-isoprostane concentration and matrix metalloproteinase type 9 (MMP-9) activity. Thoracic radiography and bronchoscopy scores were also established. Cats were investigated prior to sensitisation and after inhalation of placebo or allergen challenge 1. BWBP measurements revealed a significant increase of enhanced pause (Penh), an index of bronchoconstriction, and AR in sensitised cats in response to allergen challenge 1. A significant increase in BALF neutrophil and eosinophil %, F-2-isoprostane concentration and MMP-9 activity, and increased radiography and bronchoscopy scores were recorded. After a recovery period of 6 weeks, all variables except BALF MMP-9 returned to baseline values. Four further allergen challenges induced similar changes to those seen in challenge I and no signs of persistent changes suggestive of bronchial remodelling were detectable. The model provides an in vivo approach to functional, inflammatory and morphological changes occurring in response to single and repeated allergen exposure. [less ▲]

Voltaire n'a pas ménagé le pays de Liège. État clérical, berceau de la Fête-Dieu, la principauté était symbolisée par l'Almanach de Mathieu Laensbergh, dont les prédictions entretenaient un fatalisme obscurantiste. Le présent ouvrage montre une réalité plus contrastée, où s'entrecroisent industrie de la contrefaçon littéraire, séjours d'écrivains en cavale et grandes entreprises typographiques, pour former une toile de fond sur laquelle se détache une véritable révolution des mentalités. L'impulsion fut-elle donnée par la création en 1756 du Journal encyclopédique? L'imprimeur Bassompierre avait-il auparavant ouvert la voie en publiant Diderot, l'École de la volupté du matérialiste La Mettrie ou le Code de la nature, sorte de charte pré-socialiste? Le règne de Charles d'Oultremont installe-t-il une parenthèse pieuse avant qu'apparaisse en 1772 son successeur Velbruck, franc-maçon et modèle de «prince-évêque éclairé»? Telles sont quelques-unes des questions discutées ici. Figurant parmi les capitales européennes de la contrefaçon du livre, Liège et sa filiale maastrichtoise participeront aux premières tentatives d'édition des oeuvres complètes des philosophes : Voltaire (en trente-deux volumes!), Helvétius, Montesquieu, Beaumarchais, Raynal. L'imprimeur Clément Plomteux se spécialisera dans d'ambitieux projets de totalisation du savoir, dont une refonte de l'Encyclopédie. La poésie, réveillée par le long séjour qu'effectue à Liège l'écrivain Léonard, stimulera l'idéal d'une régénération de l'homme par le retour à la nature. La Société Libre d'Émulation (1779) fournira la caisse de résonance que réclamaient un puissant souci collectif de modernité et l'avènement d'une «société des talents». S'y joignirent des revendications de justice sociale qui se lisent dans la littérature des procès opposant nobles et communautés, ou dans l'Histoire des deux Indes de Raynal et Diderot. L'«embrasement inévitable» de 1789 n'était plus loin. [less ▲]

The objectives of the study were to measure the prevalence of periodic leg movements during NREM and REM sleep (PLMS) and while awake (PLMW) and to assess the impact of PLMS on nocturnal sleep and daytime functioning in patients with narcolepsy. One hundred and sixty-nine patients with narcolepsy and 116 normal controls matched for age and gender were included. Narcoleptics with high and low PLMS indices were compared to assess the impact of PLMS on sleep and Multiple Sleep Latency Test (MSLT) variables. More narcoleptics than controls had a PLMS index greater than 5 per hour of sleep (67% versus 37%) and an index greater than 10 (53% versus 21%). PLMS indices were higher both in NREM and REM sleep in narcoleptic patients, but the between-group difference was greater for REM sleep. A significant increase of PLMS index was also found with aging in both narcoleptic patients and controls. PLMW indices were also significantly higher in narcoleptic patients. Patients with an elevated index of PLMS had a higher percentage of stage 1 sleep, a lower percentage of REM sleep, a lower REM efficiency and a shorter MSLT latency. The present study demonstrates a high frequency of PLMS and PLMW in narcolepsy, an association between the presence of PLMS and measures of REM sleep and daytime functioning disruption. These results suggest that PLMS represent an intrinsic feature of narcolepsy. [less ▲]

Depuis une vingtaine d’années, les sociétés occidentales ont connu de profondes modifications sociales, techniques, économiques et idéologiques habituellement reprises sous le concept global de post-modernité. Or, les bases fondamentales des dispositifs de formation des adultes sont issues pour bonne partie des positions épistémologiques et méthodologiques de la psychosociologie clinique, de l’approche rogérienne de la relation et de l’approche lewinnienne du groupe telles qu’elles se sont développées en France dans les années 1960. Après avoir examiné les tensions qui existent entre ces deux modèles, nous formulons des propositions méthodologiques qui permettent d’articuler ces positions épistémologiques et méthodologiques avec les évolutions qui marquent les sociétés post-modernes.

This structured experience addresses four goals: to allow the participants to introduce themselves to each other; to facilitate interpersonal sharing; for the sessions focusing specifically on interpersonal relationships, to raise awareness of the different dimensions of interpersonal encounters; and finally, for the sessions focusing specifically on creativity, to foster reflection on the relationship between oneself, others, the work that is produced, and the audience to whom it is addressed.

Invasive exotic plants can modify soil organic matter (SOM) dynamics and other soil properties. We evaluated changes in particulate organic matter (POM) and carbon (C) mineralisation in adjacent plots invaded by Solidago gigantea, Prunus serotina, Heracleum mantegazzianum and Fallopia japonica, and non-invaded control plots on different soils in Belgium. Litter decomposition of S. gigantea and P. serotina was compared to that of the native species Epilobium hirsutum, Betula pendula and Fagus sylvatica. Disregarding the differences in site characteristics (soil texture, parental material and plant species), we argued that the invasion by S. gigantea and P. serotina enhance SOM dynamics by increasing C mineralisation in 2 out of 3 sites invaded by S. gigantea and in 1 out of 3 sites invaded by P. serotina; C in coarse POM (cPOM, 4,000-250 mu m) and fine POM (fPOM, 250-50 mu m) in 1 site invaded by S. gigantea and C content in total POM (tPOM, 4,000-50 mu m) and the organo-mineral fraction (OMF, 0-50 mu m) in 1 site invaded by P. serotina. H. mantegazzianum and F. japonica slowed down SOM dynamics by reducing C mineralisation in three out of four sites; C and nitrogen (N) of fPOM in the invaded compared with the non-invaded plots at one site invaded by H. mantegazzianum. However, N content of cPOM (4,000-250 mu m) was higher in the invaded sites by F. japonica compared with the non-invaded plots. Our results indicated that the effects of invasion by exotic plant species were not species-specific but site-specific. [less ▲]

The analysis of cultural heritage metal artefacts is essential to obtain information on the provenance, the fabrication techniques and the art history, even if it is very critical and submitted to very severe constraints of preservation. This article shows an aspect of this analysis, neglected for a too long time: the analysis of the artefacts surface and of the decorations, in particular a very specific decoration: the black intentional patinas. A specific analytical protocol based on non destructive analysis (ion beam analysis-PIXE-RBS, X-ray diffraction, Raman spectrometry...) is developed and applied to an exceptional corpus of artefacts coming from the French museum collections. This study leads to reveal and assure a better comprehension of the use by antic craftsmen of a decoration technique based on a chemical treatment, providing essential information to the history of techniques and technologies. It led also to study a surface layer on copper based alloys with a very surprising chemistry. [less ▲]
