At the instigation of the Musée du Louvre’s Department of Egyptian Antiquities, an intensive programme to study black bronze has been carried out at the Centre de Recherche et de Restauration des Muse´es de France. Systematic research has been undertaken on the museum’s collection to identify objects that might have an intentional black patina. The same experimental protocol has been applied to all the objects, alllowing this study to be one of the most important coherent investigation on this type of bronze decoration. It involves the use of non-invasive analytical methods in order to obtain the maximum amount of information possible about the chemical nature and structure of the surface layer. The protocol makes it possible to compare objects and to propose an interpretation of how this decorative technique evolved during the Egyptian period. Based on previous stylistic investigations (by J. Cooney, 1966) and personal observation, sixteen objects dating from the Middle Kingdom to the Late Period were selected. Thanks to elemental analyses, twelve of them were identified as being intentionally patinated. Only ten of these could be described as hmty-km, because the base patinated alloy contains small amounts of gold and/or silver and the black patina is made up mainly of cuprous oxide Cu2O (cuprite). Among the four other objects, one patina is very close to the black bronze patina, but contains neither gold nor silver. Three other pieces have an unusual patina. A lack of other comparable examples makes it very difficult to determine whether the patinas are of ancient origin. [less ▲]Detailed reference viewed: 124 (4 ULg)

Nanometer-sized titanium dioxide (TiO2) particles were prepared on carbon substrates by reactive direct-current magnetron sputtering. By performing measurements with high resolution electron microscopes, the mean nanoparticle diameter and the coverage fraction of the substrate by the nanoparticles (NPs) were measured at 19 nm and 30%, respectively. Moreover, electron diffraction analysis showed that the TiO2 NPs' crystalline structure on the carbon substrate was a mixture of anatase and rutile. Finally,we provided information on the TiO2 initial growth stage: crystalline NPs were formed after deposition of amorphous nanoparticles on the substrate and heating.

BACKGROUND AND AIMS: The familial Mediterranean fever (FMF) gene (MEFV) encodes pyrin, a major regulator of the inflammasome platform controlling caspase-1 activation and IL-1beta processing. Pyrin has been shown to interact with the gene product of NLRP3, NALP3/cryopyrin, also an important active member of the inflammasome. The NLRP3 region was recently reported to be associated with Crohn's disease (CD) susceptibility. We therefore sought to evaluate MEFV as an inflammatory bowel disease (IBD) susceptibility gene. METHODOLOGY AND RESULTS: MEFV colonic mucosal gene expression was significantly increased in experimental colitis mice models (TNBS p<0.0003; DSS p<0.006), in biopsies from CD (p<0.02) and severe ulcerative colitis (UC) patients (p<0.008). Comprehensive genetic screening of the MEFV region in the Belgian exploratory sample set (440 CD trios, 137 UC trios, 239 CD cases, 96 UC cases, and 107 healthy controls) identified SNPs located in the MEFV 5' haplotype block that were significantly associated with UC (rs224217; p = 0.003; A allele frequency: 56% cases, 45% controls), while no CD associations were observed. Sequencing and subsequent genotyping of variants located in this associated haplotype block identified three synonymous variants (D102D/rs224225, G138G/rs224224, A165A/rs224223) and one non-synonymous variant (R202Q/rs224222) located in MEFV exon 2 that were significantly associated with UC (rs224222: p = 0.0005; A allele frequency: 32% in cases, 23% in controls). No consistent associations were observed in additional Canadian (256 CD trios, 91 UC trios) and Scottish (495 UC, 370 controls) sample sets. We note that rs224222 showed marginal association (p = 0.012; G allele frequency: 82% in cases, 70% in controls) in the Canadian sample, but with a different risk allele. None of the NLRP3 common variants were associated with UC in the Belgian-Canadian UC samples and no significant interactions were observed between NLRP3 and MEFV that could explain the observed flip-flop of the rs224222 risk allele. CONCLUSION: The differences in association levels observed between the sample sets may be a consequence of distinct founder effects or of the relative small sample size of the cohorts evaluated in this study. However, the results suggest that common variants in the MEFV region do not contribute to CD and UC susceptibility. [less ▲]Detailed reference viewed: 67 (14 ULg)

OBJECTIVE: Treatment of depression should result in the absence of symptoms, i.e. remission, in order to restore the functional status of the patient and reduce the risk for relapse. The study assessed the current remission rates in primary care and determined the influencing factors. METHODS: 10 consecutive depressive patients treated by antidepressants for at least 3 months and not more than 12 months were screened by each investigator. Remission rates were defined using the Hamilton-Depression scale 7 items (score of 3 or less) as well as the Carroll self rating scale (score of 7 or less). In addition, patients completed the Sheehan Disability Scale (SDS). Initial severity of depression, type of treatment and socio-economic factors were collected. RESULTS: 292 general practitioners screened a total of 2630 patients. Results indicated low remission rates: 28.3% according to the clinician and 17.1% according to the patient. Absence of remission was associated with higher impairment in work, social and family life. The most frequently reported residual symptoms in nonremitters were general somatic symptoms (92%), depressed mood (92%), psychic anxiety (91%) and impaired work and activities (89%). No differences were observed in remission rates between men and women. Remission rates were significantly lower in patients living alone as compared to those living in couple or family (25.1% vs 30.2%, p=0.03), in patients with lower education (21.3% vs 32.3%, p<0.001), in patients speaking French as compared to Dutch (24.0% vs 34.0% p<0.001), and unemployed patients compared to patients having an occupation (17.1% vs 39.0%, p<0.001). Higher initial severity and number of previous episodes decreased remission rates (p<0.001). CONCLUSION: This study shows low remission rates in depressed patients treated in general practice. The absence of remission is associated with impairment in work, social and family life. Special attention should be given to identify patients who do not reach remission.

Plant defensive strategies bring into play blends of compounds dependent on the type of attacker and coming from different synthesis pathways. Interest in the field is mainly focused on volatile organic compounds (VOCs) and jasmonic acid (JA). By contrast, little is known about the oxidized polyunsaturated fatty acids (PUFAs), such as PUFA-hydroperoxides, PUFA-hydroxides, or PUFA-ketones. PUFA-hydroperoxides and their derivatives might be involved in stress response and show antimicrobial activities. Hydroperoxides are also precursors of JA and some volatile compounds. In this paper, the differential biochemical response of a plant against insects with distinct feeding behaviours is characterized not only in terms of VOC signature and JA profile but also in terms of their precursors synthesized through the lipoxygenase (LOX)-pathway at the early stage of the plant response. For this purpose, two leading pests of potato with distinct feeding behaviours were used: the Colorado Potato Beetle (Leptinotarsa decemlineata Say), a chewing herbivore, and the Green Peach Aphid (Myzus persicae Sulzer), a piercing-sucking insect. The volatile signatures identified clearly differ in function with the feeding behaviour of the attacker and the aphid, which causes the smaller damages, triggers the emission of a higher number of volatiles. In addition, 9-LOX products, which are usually associated with defence against pathogens, were exclusively activated by aphid attack. Furthermore, a correlation between volatiles and JA accumulation and the evolution of their precursors was determined. Finally, the role of the insect itself on the plant response after insect infestation was highlighted. [less ▲]Detailed reference viewed: 146 (17 ULg)

This study was aimed at investigating whether the recognition of familiar faces is more likely to be associated with an experience of Remembering than the recognition of familiar names. Using the Remember/Know paradigm the proportions of episodic memories recalled following the recognition of famous faces and names (Conditions) were assessed. Presented faces and names were previously judged by an independent group of participants as eliciting an equivalent level of familiarity. Nevertheless significant differences between the two conditions appeared in hit and false alarm rates. However, present results showed no significant difference in the recollection of personal memories (Remember responses conditionalized on the hits), following familiar faces compared with familiar names recognition. This finding contrasts with recent accounts assuming that faces are more prone to yield episodic memories than other cues to person identity. These results and their implications for current Interactive Activation and Competition person recognition models are discussed. [less ▲]Detailed reference viewed: 111 (50 ULg)

OBJECTIVE: We aimed to analyze trends in drug-eluting stents (DES) use in four international health care and regulatory settings. BACKGROUND: Accounts suggest a differential approach to DES internationally and recent reductions in use following reports of late stent thrombosis. Current studies of clinical practice are limited in their scope. METHODS: Data were pooled from angioplasty registries in Alberta (Canada), Belgium, Mayo Clinic (Rochester, MN), and Scotland (UK) that have routinely recorded consecutive patients treated since 2003. Trend analysis was performed to examine variations in DES use over time and by clinical subgroup. RESULTS: A total of 178,504 lesions treated between January 2003 and September 2007 were included. In the Mayo Clinic Registry, rapid adoption to a peak of 91% DES use for all lesions by late 2004 was observed. In contrast, Alberta and Scotland showed delayed adoption with lower peak DES use, respectively, 56% and 58% of lesions by early 2006. Adoption of DES in Belgium was more gradual and peak use of 35% lower than other registries. Reductions in DES use were seen in all data sets during 2006, although this varied in absolute and relative terms and by clinical subgroup. CONCLUSION: Adoption and use of DES showed wide variation in four countries. The determinants of use are complex, and it is likely that nonclinical factors predominate. Recent reductions in use may be as a consequence of publicity and concerns regarding late stent thrombosis. The optimum application of DES in clinical practice is unclear and is reflected in the degree of international variation demonstrated. [less ▲]Detailed reference viewed: 5 (0 ULg)

De la communication, souligner non les vertus, mais les vices ; examiner, au titre de ses pathologies - et plus spécialement de ses pathologies sociales -, non les biais dont elle peut faire l'objet, mais ceux à la source desquels il arrive qu'elle se trouve ; l'envisager, non comme facteur de prévention ou de résorption de ces pathologies, mais plutôt comme leur éventuel vecteur d'aggravation circulaire, voilà comment pourrait être résumé à grands traits le propos du dossier ouvert dans la présente livraison de Questions de communication. Programme exorbitant : quelques articles réunis pour la cause ne sauraient épuiser ni même baliser avec précision une problématique pouvant aller, de façon très reçue, des phénomènes d'addiction électronique et des syndromes de déréalisation ou d'isolement induits par les technologies du virtuel aux dispositifs de propagande et autres techniques de lissage des différends politiques ou sociaux. Programme qui n'en paraîtra pas moins incongru au regard des conceptions enchantées de la communication et de la doxa qui l'institue non seulement en principe actif de la vie sociale en général, mais encore en ressource de première nécessité et en valeur indiscutable.
