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 ▲]

Context: High angular resolution imaging of nearby pre-main sequence stars with ages between 1 and 30 Myr can give valuable information on planet formation mechanisms. This range of ages is thought to correspond to the dissipation of the optically thick dust disks surrounding young stars and to the end of the planet formation. Aims: This paper presents new observations of three weak-line T Tauri Stars (WTTS) of intermediate ages ranging from 7 to 16 Myr. It aims at increasing the knowledge and sample of circumstellar disks around "old" WTTS. Methods: We observed three stars with the VLT's NAOS-CONICA adaptive optics system in coronagraphic mode. The four-quadrant phase mask coronagraph was used to improve the dynamic range (by a factor of 100) while preserving the high angular resolution (inner working angle of 0farcs 15). Results: One object of our sample (PDS 70), a K5 star, exhibits a brown dwarf companion and a disk in scattered light with a surface brightness power law of r[SUP]-2.8[/SUP], extending from a distance of 14 to 140 AU (assuming a stellar distance of 140 pc) and an integrated luminosity of 16.7 mJy in the K_s-band. The mass of the companion can be estimated to be within a range between 27 and 50 Jupiter masses with an effective temperature of 2750 ± 100 K. This object also shows a resolved outflow stretching up to 550 AU. Conclusions: This newly detected circumstellar disk shows strong similarities with the disk around TW Hya, and adds to the observed population of "old" TTS surrounded by circumstellar material. Moreover, three clues of planetary formation are brought to light by this study. [less ▲]

Recent publications about carotid-stenting are submitted to a critical analysis. The fact that an interventional approach in asymptomatic carotid lesions generates only marginal benefit being universally admitted, it is disturbing to see that modern series devoted to carotid artery stenting include a lot of asymptomatic patients and many symptomatic patients with a degree of stenosis well below the optimal range defined in NASCET (70 to 99%). Moreover, the degree of stenosis is often calculated from an inappropriate method that overestimates the degree of stenosis. Two objections have been made about an "hyper-selection" of the patients enrolled in the NASCET study and the production of ideal not realistic results, not attainable in community hospitals; both objections have been overruled. The rate of acute perioperative myocardial infarction is mentioned, both in NASCET and ECST, it is around 0.9% vs 7.5% in SAPPHIRE study. Moreover, carotid artery stenting with an embolic protection device has resulted in the production of infra-clinical cerebral micro-infarcts in 40% of the patients. Significantly, the independent study EVA-3S, devoted to symptomatic patients had to be stopped because of the high cerebral morbidity in the dilatation-stenting group. Carotid artery stenting of asymptomatic lesions is futile (and potentially harmful because of microinfarcts) while carotid artery stenting of symptomatic lesions generate emboli. [less ▲]

Primary aorto-oesophageal fistula, secondary to an aneurysm of the thoracic aorta, are almost fatal. In the literature, only twenty six successfully operated cases have been reported. We report the case of a 78-year-old man with a thoracic aortic aneurysm eroded into the mid oesophagus. Prompt diagnosis of an aorto-oesophageal fistula resulted from clinical history, CT-imaging and oesophagoscopy. The patient was successfully operated by exclusion of the thoracic aneurysm (insertion of a straight cryopreserved arterial allograft), oesophagectomy and cervical oesophagostomy and jejunostomy. The continuity of the digestive tube was later restored after preliminary aortic valve remplacement (stenosis of 0.8 cm2). This case report is the second in which a cryopreserved allograft was successfully implanted in the management of a primary aorto-oesophageal fistula. [less ▲]
