Le nez électronique avec une configuration très simple fournit des résultats encourageants pour détecter une odeur dans l’environnement. Il existe un réel espoir de pouvoir fabriquer des instruments portables capables de prévoir une odeur inconnue en temps réel sur le terrain. Le monitoring des odeurs environnementales est un challenge, mais une simple estimation est suffisante, il n'y a pas besoin de conditions opératoires très rigoureuses. Il reste néanmoins beaucoup de travail à faire avant que le nez électronique ne devienne une réalité dans l’environnement. La communication présente ce challenge en l'illustrant par de nombreuses applications réalisées par l'équipe de recherche. [less ▲]

The introduction sets the scene of the present paper i.e. the extensive research works performed at the University of Liege in order to derive acceptable calculation methods for the re design of concrete columns. It is explained that all previous works have been based on square or rectangular cross sections, for which corner spalling was observed very often, whereas circular section are nowadays becoming more and more popular. In order to examine the influence of the circular shape on the behavior under re conditions, an experimental research study has been performed recently at the University of Liege. This paper describes the test procedure, the observations made, and the values obtained for the re resistance. Theoretical methods have been developed for a quick, safe, and efficient design of concrete columns under re conditions. These methods have been applied successfully to the recently tested circular columns. [less ▲]

This paper presents a reflection about the key success factors involved in the process of turning traditional courses into on-line active courses. Within the context of ‘FORMADIS’ and other programmes, more than twenty projects have been accompanied by the LabSET in the past 3 years. The paper gives an overview of the tools and methods used for teacher support and training. It examines the projects ‘doing well’ and analyse what makes them sucessful. It considers the moment at which the success factors take place (before, during and after the various phases of development). It illustrates these key factors with practical examples. Whereas the majority of these factors seem to be obvious, this analysis will help considering the relations between them as well as the way of managing them successfully. [less ▲]

En ce début de siècle, nous assistons à un changement du type de violence associé aux manifestations sportives, notamment aux matches de football. En effet, la violence dans le sport, qui se cantonnait aux stades de football et avait un caractère exceptionnel et spontané, a gagné les zones urbaines et le coeur des villes. La société contemporaine est désormais confrontée à une violence dans le sport souvent préméditée et généralement provoquée par un noyau dur de supporters qui recherchent la confrontation systématique et organisée, lors des matches et des tournois locaux, nationaux et internationaux. Etant donné que le hooliganisme devient international et crée des problèmes similaires en Europe et partout dans le monde, il est nécessaire de lui apporter, à l’échelle internationale, une réponse commune et concertée, axée sur la prévention. La prévention de la violence dans le sport propose des actions et des structures fondées sur des expériences en cours qui ont montré une certaine efficacité. Ces initiatives donnent une gamme de solutions permettant de mettre en place des activités de prévention intégrées de haut niveau, qui peuvent être adaptées aux besoins locaux. [less ▲]

The beginning of this century has seen a shift in the type of violence associated with sports events, in particular football. Once contained by football grounds and generally one-off and spontaneous in nature, sports violence has moved to urban areas and city centres. Contemporary society is now confronted with sports violence which is often premeditated, and commonly involves hard-core supporters who seek systematic and organised confrontation at local, national and international matches and tournaments. As hooliganism becomes international, generating similar problems in Europe and throughout the world, a common and concerted preventive response at international level is needed. The prevention of violence in sport proposes actions and structures based on experiments in progress which have already shown some degree of effectiveness. These initiatives open up a range of solutions for developing integrated preventive activities of a high standard that can be adapted to local needs. [less ▲]

The effect of manipulation and distracting noise on immediate serial recall was measured in patients with dementia of the Alzheimer type (DAT), neurologically healthy elderly individuals and young adults. In experiment 1, the authors compared serial word recall with word recall in alphabetical order. Alphabetical recall requires the active manipulation of the contents of working memory. Findings indicated that DAT patients were severely impaired in the alphabetical recall task, whereas the performance of neurologically healthy elderly participants was comparable with the performance of young adult participants. In experiment 2, the authors investigated the effect of different irrelevant auditory backgrounds on immediate digit recall. In this task, both elderly participants and DAT patients performed similarly to the group of young adult participants, indicating comparable efficacy to resist auditory distraction. [less ▲]

Purpose: The purpose of this study was to assess the activity and toxicity of a combined regimen of topotecan and cisplatin in "sensitive" (s) and "refractory" (r) small-cell lung cancer (SCLC) patients treated previously. Experimental Design: Patients with measurable SCLC and progressive disease after one first-line regimen were eligible for the study. Patients were enrolled in two separate groups: r group (patients who failed first-line treatment <3 months from treatment discontinuation) and s group (patients who responded to first-line treatment and progressed 2:3 months after treatment discontinuation). Cisplatin was given i.v. at the dose of 60 mg/m(2) on day 1, and topotecan was administered as a daily i.v. infusion at the dose of 0.75 mg/m(2) from day 1 to 5, every 3 weeks. Results: A total of 110 eligible (68 s and 42 r) patients were enrolled from 24 institutions. The main patient characteristics were as follows: median age 60 (s) and 55 (r) years, median performance status 1 for both (s) and (r). Seventy-four percent (s) and 67% (r) had extensive stage disease, including 22% and 36%, respectively, with brain metastases. A total of 398 chemotherapy courses were administered [median 4 (s) and 3 (r) per patient]. The most frequent and serious toxicity was myelosuppression. Grade IV neutropenia occurred in 62% (s) and 49% (r) of patients, with a 19% (s) and 15% (r) incidence of febrile neutropenia, and grade IV thrombocytopenia in 54% (s) and 44% (r). Most of these toxicities occurred during the first chemotherapy course and led to topotecan dose reduction and/or delay in the following courses. Grade III-IV nonhematological toxicity was uncommon. Five deaths possibly related to toxicity occurred among s patients only. Objective responses have been documented in 20 s patients, 19 partial responses and 1 complete response, (29.4% response rate; 95% confidence interval, 19-42), whereas, among r patients, 10 partial responses have been observed (23.8% response rate; 95% confidence interval, 12-39). Median survival for s and r was 6.4 and 6.1 months, respectively. Conclusions: The combination of cisplatin and topotecan, at this dose and schedule, shows activity and promising results in patients with refractory SCLC, with reversible myelosuppression being the main side effect. Additional development of this regimen, using better-tolerated schedules, is warranted in patients with refractory SCLC. [less ▲]

Variable numbers of CD34(+) cells can be harvested from the blood of AML patients in CR after G-CSF supported mobilization following consolidation chemotherapy. We hypothesized that a decreased ability to mobilize stem cells reflects a chemotherapy-induced reduction in the number of normal and leukemic stem cells. We therefore analyzed whether the mobilizing capacity of these patients was of prognostic significance. 342 AML-patients in first CR received daily G-CSF from day 20 of the consolidation course and underwent 1-6 aphereses to obtain a minimum dose of 2 x 10(6) CD34(+) cells/kg. Afterwards they were randomized for autologous bone marrow (M) or blood SCT. As a surrogate marker for the mobilizing capacity, the highest yield of CD34(+) cells of a single apheresis was adopted. Patients could be categorized into four groups: no harvest (n = 76), low yield (<1 x 10(6) CD34(+)/kg; n = 50), intermediate yield (1-6.9 x 10(6) CD34(+) cells/kg; n = 128) and high yield ( :7 x 106 CD34+ cells/kg; n = 88). The median follow-up was 3.4 years; 163 relapses and 16 deaths in CR were reported. Autologous blood or BM SCT was performed in 36%, 64%, 81% and 88%, respectively, of the patients assigned to the no harvest, low, intermediate and high CD34(+) yield group. The 3-year disease-free survival rate was 46.7%, 65.0%, 50.4% and 26.9% (P= 0.0002) and the relapse incidence was 47.5%, 30.1%, 43.1% and 71.9% (P < 0.0001). Multivariate Cox's proportional hazards model showed that the CD34(+) yield was the most important independent prognostic variable (P = 0.005) after cytogenetics. Patients with the highest mobilizing capacity have a poor prognosis due to an increased relapse incidence. [less ▲]

Qualitative characteristics of cryptomnesia, or unintentional plagiarism were investigated. In Experiment I we compared accurate and inaccurate source attributions in terms of their level of confidence using instructions that did not require a fixed number of responses. Confidence was lower for plagiarised responses than for correct responses. Nevertheless, participants provided high ratings of certainty for a large proportion of their plagiarised responses. In Experiment 2 the phenomenological differences between plagiarised recall and veridical recall were compared by using an adaptation of the memory characteristics questionnaire (Johnson, Foley, Suengas, [less ▲]

Thiopurine S-methyltransferase (TPMT) deficient patients develop life threatening haematoxicity (for example, pancytopenia) when treated with a standard dose of azathioprine (AZA) and 6-mercaptopurine (6-MP) due to excessive accumulation of cytotoxic metabolites. At present, it is generally recommended that these patients should not receive AZA or 6-MP treatment for inflammatory bowel disease. We report for the first time that Crohn's disease patients with TPMT deficiency can be successfully treated with AZA. We illustrate this with three cases where treatment has been successful and toxicity has been avoided by carefully titrating the drug dose. Thus very low TPMT activity demands pharmacogenetically guided dosing. [less ▲]

El segundo propósito es plantear el pluralismo como principio fundamental que orienta y describe la acción del Estado Social de Derecho hacia el reconocimiento efectivo de las diversidades que conforman el pueblo colombiano. Se intenta demostrar, que la integración nacional sólo se logra cimentando la identidad cultural sobre el diálogo intercultural y la disposición abierta a la interacción con otras culturas dentro y más allá del ámbito Estatal.

The discovery of an anterior asymptomatic mediastinal mass with acromegaly creates a dilemma for the clinician. As acromegaly can be due to a pituitary tumor but also to an ectopic production of GHRH, the first diagnostic step consists of finding the etiology of the disease in order to use adequate treatment. This can be complicated by the fact that acromegaly can be associated with other tumors (for instance in MEN-1 disease and Carney Complex) and because chronic GH hypersecretion can stimulate tumor overgrowth and perhaps tumor formation. We describe the case of a 44-year-old acromegalic woman with an anterior mediastinal mass. We present the different diagnoses and a review of the literature. [less ▲]
