A real-time immunoquantitative PCR (iqPCR) method for detection of Staphylococcus aureus enterotoxin B (SEB) was developed and evaluated using both pure cultures and foods. The assay consisted of immunocapture of SEB and real-time PCR amplification of the DNA probe linked to the detection antibody. iqPCR was compared to an in-house enzyme-linked immunosorbent assay (ELISA) using the same couple of capture-detection antibodies and to commercial kits for detection of S. aureus enterotoxins (SE). The iqPCR was approximately 1,000 times more sensitive (< 10 pg ml(-1)) than the in-house ELISA and had a dynamic range of approximately 10 pg ml(-1) to approximately 30,000 pg ml(-1). iqPCR was not inhibited by any of the foods tested and was able to detect SEB present in these foods. No cross-reactivity with SE other than SEB was observed. Application of iqPCR for detection of SEB in cultures of S. aureus revealed the onset of SEB production after 4 It of incubation at 22, 37, and 42 degrees C, which was in the first half of the exponential growth phase. The total amounts of SEB produced by the two strains tested were larger at 42 degrees C than at 37 degrees C and were strain dependent. [less ▲]

The study is conducted in the frame of a programme of monitoring of all landfill sites in Wallonia. The "odour" part is assigned to ULg. The present report concerns more particularly a second campaign on the site of Hallembaye. The research group applied the usual field inspection technique to assess the global odour emission rate generated by the site. The influence of relief is particularly discussed with the results of 3D modelling. [less ▲]

Hypersensitivity to electricity has been reported many times in the literature. From another point of view, numerous measurements have been performed on perception level. Even if it appears that part of the population has a lower perception level of current, there is no clear link with the so called “hypersensitivity to electricity” which is more related to declared physiological disorders in part of the population (sleeping problem, headache ...). Such declared hypersensitivity is currently not yet related to any biological parameter. Our research team is currently trying to determine a relationship between hypersensitive declared people and the perception level when injecting current in the low frequency range 50-1000 Hz. We have performed current perception tests with individuals under different conditions (different wave shapes, frequencies, influence of external electric field, male and female...) using a particular protocol and our own designed system for current injection. This paper will present our test system design (current injector, wave shape converter, safety aspects) and our first results based on both sine wave (different frequencies) and wide band signal.

Recent studies point to an important role for the main olfactory epithelium (MOE) in regulating sexual behavior in male mice. We asked whether sexual experience could compensate for the disruptive effects of lesioning the MOE on sexual behavior in male mice. Male mice, which were either sexually naive or experienced, received an intranasal irrigation of either a zinc sulfate solution to destroy the MOE or saline. Sexual behavior in mating tests with an estrous female was completely abolished in zinc sulfate-treated male mice regardless of whether subjects were sexually experienced or not before the treatment. Furthermore, zinc sulfate treatment clearly disrupted olfactory investigation of both volatile and nonvolatile odors. Destruction of the MOE by zinc sulfate treatment was confirmed by a significant reduction in the expression of Fos protein in the main olfactory bulb following exposure to estrous female urine. By contrast, vomeronasal function did not seem to be affected by zinc sulfate treatment: nasal application of estrous female urine induced similar levels of Fos protein in the mitral and granule cells of the accessory olfactory bulb (AOB) of zinc sulfate- and saline-treated males. Likewise, the expression of soybean agglutinin, which stains the axons of vomeronasal organ neurons projecting to the glomerular layer of the AOB, was similar in zinc sulfate- and saline-treated male mice. These results show that the main olfactory system is essential for the expression of sexual behavior in male mice and that sexual experience does not overcome the disruptive effects of MOE lesioning on this behavior.

Allogeneic hematopoietic cell transplantation ( HCT) following nonmyeloablative conditioning has been extensively evaluated in patients with hematologic malignancies who are ineligible for conventional HCT because of age or medical comorbidities. Nonmyeloablative regimens have led to an initial state of mixed hematopoietic chimerism defined as coexistence of donor- and host-derived hematopoiesis. While nonmyeloablative regimens have been associated with reduced regimen-related toxicities in comparison with conventional myeloablative conditioning, graft rejection, graft-versus-host disease ( GVHD), and disease progression have remained significant challenges. In this article, after briefly introducing current techniques for chimerism assessment, we describe factors affecting donor chimerism levels after nonmyeloablative conditioning, and then review data suggesting that chimerism assessment early after HCT might help identify patients at risk for graft rejection, GVHD and relapse/progression. Finally, we discuss how these observations have opened the way to further research protocols evaluating manipulation of postgrafting immunosuppression, and/or infusion of donor immune cells.

Objective. To evaluate whether implementation of discharge management by trained social workers or nurses reduces hospital readmissions and institutionalizations of geriatric patients in a real-world setting. Design. Quasi-experimental design. Setting. Six general hospitals in Belgium. Participants. A representative sample of 824 patients, 355 of whom were assigned to the experimental group receiving comprehensive discharge management and 469 to the control group receiving usual care. Inclusion criteria were patients admitted to a geriatric, rehabilitation, or internal medicine ward, not residing in a nursing home, and showing risk of readmission or institutionalization on admission in the hospital. Intervention. In-hospital discharge planning according to a case management protocol allowing for adjustment to participating hospitals' case mix and patients' and families' specific needs. Main outcome measures. Hospital readmission within 15 and 90 days post discharge; institutionalization at discharge and within 15 and 90 days post discharge. Results. Discharge management resulted in fewer institutionalizations (n = 53; 14.9%) compared with usual care (n = 130; 23.7%) (adjusted odds ratio = 0.47; CI 95% = 0.31-0.70). Readmission rates between the intervention and usual care group were not significantly different. Conclusions. This implementation project showed that a discharge planning intervention can reduce institutionalization rates of elderly patients in real-life settings. [less ▲]

Un diamant correspond à l'existence de plusieurs chemins alternatifs entre deux points du réseau. Cette notion joue un rôle important en ingénierie du trafic où il faut, par exemple, répartir la charge de trafic entre plusieurs chemins. Ces diamants peuvent être présents au niveau SA ou au niveau IP. Cet article s'intéresse au niveau IP et propose une méthode récursive d'étiquetage des diamants, RLPA. Nous avons appliqué RLPA sur un sous-ensemble des données skitter. Nous montrons, sur le sous-ensemble observé, que les diamants sont majoritairement composés d'un seul noeud intermédiaire, qu'ils sont formés de deux chemins alternatifs, qu'ils sont essentiellement symétriques et qu'ils se situent entre 10 et 15 sauts de la source du traceroute.

In the past few years, the network measurement community has been interested in the problem of internet topology discovery using a large number (hundreds or thousands) of measurement monitors. The standard way to obtain information about the internet topology is to use the traceroute tool from a small number of monitors. Recent papers have made the case that increasing the number of monitors will give a more accurate view of the topology. However, scaling up the number of monitors is not a trivial process. Duplication of effort close to the monitors wastes time by reexploring well-known parts of the network, and close to destinations might appear to be a distributed denial-of-service (DDoS) attack as the probes converge from a set of sources towards a given destination. In prior work, authors of this paper proposed Doubletree, an algorithm for cooperative topology discovery, that reduces the load on the network, i.e., router IP interfaces and end-hosts, while discovering almost as many nodes and links as standard approaches based on traceroute. This paper presents our open-source and freely downloadable implementation of Doubletree in a tool we call traceroute@home. We evaluate the performance of our implementation on the PlanetLab testbed and discuss a large-scale monitoring infrastructure that could benefit of Doubletree. [less ▲]

Prion cell tropism varies significantly among animal species, depending on both the agent strain and host-specific factors. For example, prions show high lymphotropism in scrapie infected sheep and vCJD, but little, if any, in sCJD or BSE. In particular, the BSE strain is associated with significant PrP-res accumulation in tonsils, spleen and appendix in humans, whereas it is largely confined to the nervous system in infected cattle. Therefore, at least in the case of BSE and vCJD, it appears that host properties can influence the accumulation of the infectious agent in lymphoid organs. Mature FDC play an important role in prion pathogenesis, since neuroinvasion following peripheral challenge is significantly impaired in their absence. The proximity between these FDC and sympathetic nerve endings is known to affect the speed of prion neuroinvasion. In this study, we analysed the mucosal innervation and the interface between nerve fibres and FDC in bovine and human tonsils and in ileal and jejunal bovine Peyer’s patches using a panel of antibodies observed by confocal microscopy. Since differences in the innervation of lymphoid organs depending on age have been reported, we analysed three categories of bovine ages (new born calves, calves less than 12 months old and bovines older than 24 months) and two categories of human ages (patients less than 5 years old and patients older than 25 years). In both species, hypothetical ways of innervation by-passing germinal centre could be postulated: nerve fibres are widely distributed in antigens/cells traffic area (the lamina propria, the interfollicular zone, the suprafollicular dome in Peyer’s patches and the lymphoepithelial area in tonsils). We pointed out that, only in ileal and jejunal Peyer’s patches and in tonsils of bovines older than 24 months, nerve fibres are observed to be in contact with FDC. In contrast, in human tonsils, no nerve fibres established contact with FDC, whatever the age. Thus, innervation of germinal centres can be said to be an age-dependent dynamic process in bovines and a weak innervation of the secondary lymphoid organs could thus be a rate-limiting step to neuroinvasion in humans. This variation could influence the way of neuroinvasion and thus, the differences of susceptibility of bovines and humans to the BSE agent. [less ▲]

Glick and Fiske's (1996) Ambivalent Sexism Inventory is a measure of hostile sexism (sexist antipathy) and benevolent sexism (a subjectively positive attitude toward women). This paper proposes a French version of this scale, the Echelle de Sexisme Ambivalent (ESA). Three studies on more than 1000 participants established the validity of this new scale. The first one is the application of Rasch's extended model that confirmed the psychometrical qualities of the ESA, for both male and female participants. The second study established the structural and predictive validity in a covariance analysis. This study again showed that both male and female participants displayed the same structural pattern. Next, both discriminant and convergent validity were assessed, by comparison to the Neosexism Scale (Tougas, Brown, Beaton and Joly, 1995) and the Social Dominance Scale (Sidanius and Pratto, 1999). Finally, practical and theoretical implications are discussed. [less ▲]
