Les articles sur le devenir de l'Eglise catholique en Belgique mettent souvent en évidence le renouveau des pratiques dans certains groupes de la population, mais négligent l'apport des enquêtes quantitatives, qui montrent que, selon tous les critères possibles, la sécularisation de la société belge se poursuit : non seulement les pratiques, mais les croyances, se regugient dans la partie la plus âgée de la population et concernent un nombre toujours décroissant de personnes. Ce qui n'exclut pas le maintien d'une forme de "spriritualité religieuse" assez floue dans une partie significative de ceux qui ont abandonné les pratiques classiques. [less ▲]

A vast body of experimental in vitro work and modelling studies suggests that the firing pattern and/or rate of a majority of midbrain dopaminergic neurons may be controlled in part by Ca2+-activated K+ channels of the SK type. However, due to the lack of suitable tools, in vivo evidence is lacking. We have taken advantage of the development of the water-soluble, medium potency SK blocker N-methyl-laudanosine (CH3-L) to test this hypothesis in anaesthetized rats. In the lateral ventral tegmental area, CH3-L iontophoresis onto dopaminergic neurons significantly increased the coefficient of variation of their interspike intervals and the percentage of spikes generated in bursts as compared to the control condition. The effect of CH3-L persisted in the presence of a specific GABA(A) antagonist, suggesting a direct effect. It was robust and reversible, and was also observed in the substantia nigra. Control experiments demonstrated that the effect of CH3-L could be entirely ascribed to its blockade of SK channels. On the other hand, the firing pattern of noradrenergic neurons was much less affected by CH3-L. We provide here the first demonstration of a major role of SK channels in the control of the switch between tonic and burst firing of dopaminergic neurons in physiological conditions. This study also suggests a new strategy to develop modulators of the dopaminergic (DA) system, which could be of interest in the treatment of Parkinson's disease, and perhaps other diseases in which DA pathways are dysfunctional.

This paper presents an on-line system for capturing and interpreting architectural sketches. The prototype is based on a multi-agent system, which enables real-time management of recognition scenarios. We describe the different types of agents, their characteristics, the basic mechanisms involved in interpreting freehand architectural drawings and the collaboration modes between agents. Finally, we illustrate the general operations of the system by a short example. r 2005 Elsevier Ltd. All rights reserved. [less ▲]

The aim of this study was to compare the socioeconomic consequences of early and late rheumatoid arthritis in Belgium and to assess the patient out-of-pocket contributions. This multicentre longitudinal study in Belgium evaluated patients with rheumatoid arthritis. Early disease was defined as diagnosis since less than 1 year. At baseline sociodemographic and disease characteristics were assessed and during the following year patients recorded all healthcare- and non-healthcare-related direct costs and out-of-pocket contributions. The study included 48 patients with early and 85 patients with late rheumatoid arthritis. Mean disease duration was 0.5 vs 12.5 years in patients with early and late rheumatoid arthritis, respectively. The disease activity score (DAS28) was comparable between both groups (4.1 vs 4.5, p=0.14), but physical function (Health Assessment Questionnaire, HAQ) was more impaired in patients with long-standing disease (1.0 vs 1.7, p < 0.001). Work disability had increased from 2% in patients with early to 18% in patients with late disease. The annual societal direct costs per patient were E 3055 (median: E 1518) opposed to E 9946 (median: E 4017) for early and late rheumatoid arthritis, respectively. The higher direct cost for patients with long-standing disease was seen for all categories, but especially for physiotherapy and need for devices and adaptations. Patients with early as well as late disease contribute out of pocket about one-third to the direct healthcare costs. Within each group, HAQ was a strong determinant of costs. In Belgium, patients with long-standing rheumatoid arthritis are nine times more likely to be work disabled than patients with less than 1 year disease duration and have a threefold increase in costs. Differences in healthcare consumption between patients could be mainly explained by differences in physical function (HAQ). [less ▲]

Excitatory amino acids, glutamate in particular, have a marked stimulatory effect on the reproductive axis, particulary at puberty. Glutamate, N-methyl-D-aspartate (NMDA), and kainate stimulate gonadotropin-releasing hormone (GnRH) secretion in immature mammals and NMDA receptor stimulation results in precocious puberty in rats and monkeys. Puberty is characterized by an increased sensitivity of GnRH to glutamate as well as an increase in glutaminase activity in the hypothalamus. Glutamatergic and GABAergic regulation of GnRH secretion seem strongly interdependent around puberty. in addition to the transsynaptic glutamatergic regulation of GnRH secretion, a coordinated activity of glutamatergic neurons and astroglial cells has been shown to play an active role in puberty. The participation of kainate receptors in the estradiol-induced advancement of puberty suggest that these receptors may be involved in the estradiol-mediated activation of GnRH secretion at puberty. A case of precocious puberty associated with hyperglycinemia illustrates the NMDA involvement in puberty in humans. in this patient, the occurrence of precocious puberty was thought to result from excessive stimulation by glycine of the NMDA receptors linked to the GnRH neurons. Glutamate plays several roles in the hypothalamic mechanism of puberty as it has been shown in animal models, but there are still few clinical data supporting the role of glutamate in human puberty.
