We use an extensive set of spectroscopic observations to reinvestigate the properties of the massive binary HDE 228766. Conventional classification criteria suggest that HDE 228766 consists of an O7 primary and an Of(+) secondary. However, several spectral features of the secondary, such as the simultaneous presence of N III, N IV and N V emissions, make it a rather unusual object. We find that the orbital motion of the secondary is probably best described by the radial velocities of the narrow N III emission lines. Our orbital solution yields m(1) sin(3) i = 31:7 and m(2) sin(3) i = 25:5 M. for the primary and secondary respectively. The He II lambda 4542 absorption in the secondary's spectrum appears considerably blue-shifted with respect to the narrow emission lines, indicating that the absorption is probably formed in the accelerating part of the secondary's wind. We use a tomographic technique to investigate the profile variability of the broader emission lines. In addition to a strong emission from the secondary, the Halpha line displays a weak emission feature that is probably associated with a wind interaction region located near the surface of the primary star. Finally, our analysis of the spectrum with a non-LTE code indicates that the secondary is an evolved object that exhibits some CNO processed material in its atmosphere and has a large mass loss rate. Assuming a distance of 3.5 kpc (which follows from adopting M-V,M-s = -6 for the secondary) we infer (M) over dot similar or equal to 10(5) M. yr(-1) for the secondary. Our results suggest that HDE 228766 could be in a post-Roche lobe overflow stage. The secondary may be classified as WN8ha and is currently in a transition stage between a "normal" Of staranda WNL-type Wolf-Rayet star. [less ▲]

BACKGROUND: Using clinical symptoms alone to inform treatment decisions in Crohn's disease (CD) may increase the risk of disease progression and complications. Treatment beyond symptoms may offer improved outcomes. METHODS: We explore alternative definitions of remission, beyond traditional clinical remission, incorporating more objective parameters of inflammation control, which may support prevention or delay the disease progression. These definitions could serve as a platform for future clinical research, evaluating whether treating beyond symptoms alters the natural history of CD. RESULTS: Proposed definitions may include endoscopic remission (mucosal healing), normalization of serologic or fecal markers of inflammation, and even radiographic remission, in addition to clinical remission (symptom control). Endoscopic remission is the leading candidate for inclusion because it is the best studied. The definition should include considerations for both early and late disease given that in late disease, which may be associated with operation-related symptoms or irreversible bowel damage, symptomatic remission may not achievable. Desired outcomes in early disease are complete absence of symptoms, no disease progression, no complications or disability, and normal quality of life. In late disease, there are stabilization of noninflammatory symptoms, no progression of damage or disability, and improved quality of life. CONCLUSIONS: Over time, we anticipate that a working definition of remission that includes both biological remission and clinical remission will evolve and be evaluated in clinical trials. Our proposed definition is a possible starting point for that evolution. Ultimately, the goal in evolving the definition of remission is to improve the outcomes in patients with CD. [less ▲]

Science, technology and innovation (STI) policies have gone through deep changes since the early 80’s. Multiple scholars have shown that there are new forms of links, or a renewed “contract” between science, as an institution, and the society: effects of neoliberalism, public controversies or technology assessment (TA) practices are some common features of this transformation. Innovation is pushed forward by policymakers as a crucial tool for economic growth and competitiveness of political entities. In other words, there is a new regime of STI governance. As a PhD student, I investigate the policies of science and innovation in Belgium. Since the regionalization of these competences in the 1980’s, the STI regimes have evolved separately in Flanders and Wallonia. The goal of my research is to depict and compare how constitutive elements of the regimes such as discourses, tools, institutions, networks, etc. have changed in the two Regions. Adopting a cognitive approach in policy analysis, I focus on the imaginaries or master narratives that shape programs and individuals at different policy levels. These levels range from the “micro” (individual interactions in the institutions) to the “macro” (the EU and OECD), the “meso” level being the core of the research question (regional programs and institutions). I seek to point out the local enactment of ideas such as “regional competitiveness”, “innovation-led growth”, “clustering” and its impact on STI regime. The research relies on document analysis, participant observation, and in depth semi-structured interviews designed as life stories of key STI informants. [less ▲]

Our interest is to understand the challenges to modern science and innovation regimes under conditions of globalization and “multiple modernities” (Eisenstadt 2000). Different scholarly attention has been paid to existing institutions that may no longer be adequate to address those challenges. This may be because modern institutions are pressured for a greater reflexive opening up of their structures (Beck and Lau 2005) or because the modern world-system is facing severe turbulences that would ultimately lead to a time of structural dissolution (Wallerstein 2005). This renders it interesting to trace the responses to these challenges, and we suggest doing it in the field of STS. Our ongoing multi-level comparative research takes Latin American countries as an entrance point to finding responses that are different from those occurring in European countries. Our presentation is based on Argentina and it focuses on biotechnology in agriculture. Argentina today is the second largest exporter of GM crops and it has been the first country in Latin America to establish a professional regulatory framework in the early 1990s. GM soya crop is specifically analysed because of its importance — more than 60% of the cultivated areas — and its controversial aspect : it is presented at the same time as an elixir for agro-industrial ills and as a techno-economic network increasing the benefits of the global North while dramatically affecting public health and the environment. We suggest diagnosing developments and perceptions of issues related to health, economy, ecological diversity, fertility of soils, regulation and intellectual property. [less ▲]

Our interest is to understand the challenges to modern (national) science and innovation regimes under conditions of globalization and “multiple modernities” (Eisenstadt 2000). Different scholarly attention has been paid to existing institutions that may no longer be adequate to address those challenges. This may be because modern institutions are pressured for a greater reflexive opening up of their structures (Beck and Lau 2005) or because the modern world-system is facing severe turbulences that would ultimately lead to a time of structural dissolution (Wallerstein 2005). This renders interesting to trace the responses to these challenges, and we suggest to do it in the field of science, technology and society, one where we can make a contribution. Unlike many studies mainly focusing on European models and regimes, our ongoing multi-level comparative research takes Latin American countries as an entrance point to finding responses that are different from those occuring in European countries. Latin American countries are interesting to study in this respect because institutions of science and technology have not been set up in the same way as in Europe and the governance patterns have been different. Our presentation is based on one country, Argentina, and focuses on one important sector: biotechnology in agriculture. Argentina is taken as a central case study because in addition of being today the second largest exportator of GM crops (behind the US and before Brasil), it has been the first country in Latin America to establish a professional regulatory framework in the early 1990s, looking at ecological, health and commercial aspects. GM soya crops is specifically analysed because of its importance — GM soya represents 60% of the cultivated areas — and its controversial aspect : the « GM soya model » is presented at the same time as an elixir for agro-industrial ills and as a techno-economic network increasing the benefits of the global North while dramatically affecting public health and the environment in Argentina. We suggest to diagnose developments and perceptions of issues related to health, economy, ecological diversity, fertility of soils, regulation and intellectual property. Our methodology favours qualitative data collection (individual interviews with key actors of science and innovation) and analysis, while using quantitative data when available and relevant.

The reference to historical imaginaries and legitimizations for territorial settlements after a military conflict can be considered « classical ». This contribution aims to show how Carolingian and Lotharingian imaginaries influenced certain actors of expansionist movements in Belgium after 1945, the continued existence of which constituted an echo of 1918. Even if the Belgian territorial demands at the expense of Germany were, after all, hardly grounded in such discourses, this contribution highlights the fact that the discourse aiming to transform Aix-la-Chapelle and Cologne into “Belgian” cities, insisting on the kinship between “Belgians” and “Rhinelanders”, would serve as base for the rapprochement between old enemies in the 1950s. From then on, the historical landscape between Meuse and Rhine was integrated in the discourse on the “Occident” (the West) the political organization of which was considered as of utmost necessary, given the impending Soviet menace.

Alcelaphine herpesvirus 1 (AlHV-1), carried by wildebeest asymptomatically, causes malignant catarrhal fever (WD-MCF) when cross-species transmitted to a variety of susceptible species of the Artiodactyla order. Experimentally, WD-MCF can be reproduced in rabbits. The lesions observed are very similar to those described in natural host species. Recently, we demonstrated that WD-MCF induced by AlHV-1 in rabbits is associated with the proliferation of CD8+ cells supporting a latent type of infection. In the present study, we investigated whether the virus could be detected ex vivo in the tissues of rabbits developing WD-MCF. Taking advantage of the recent cloning of the AlHV-1 genome as a bacterial artificial chromosome (BAC), we produced a recombinant plasmid encoding a firefly luciferase (LUC) expression cassette inserted in a non-coding region of the AlHV-1 genome. In vitro, the reconstituted AlHV-1 LUC strain replicated comparably to the parental strain in permissive cells and was able to induce a bioluminescent signal. In vivo, rabbits infected with the AlHV-1 LUC strain developed WD-MCF similarly to the parental wild-type strain with hyperthermia, increased CD8/CD4 ratio and viral genomic charge over time in PBMC and in lymph nodes at time of death. To identify the presence of AlHV-1 infection ex vivo, various organs of infected rabbits developing WD-MCF were analysed by bioluminescent imaging. Luciferase activity could be detected macroscopically at the time of death in most of analyzed organs including lung, popliteal and mesenteric lymph nodes, spleen, liver, kidney and appendix. Infectious virus could be isolated following co-cultures of lymph node and permissive cells, and the isolated virus retained the ability to induce a bioluminescent signal. In conclusion, we produced an AlHV-1 LUC recombinant and we were able to detect the AlHV-1 infection ex vivo in many organs at the time of death. [less ▲]

Alcelaphine herpesvirus 1 (AlHV-1), carried by wildebeest asymptomatically, causes malignant catarrhal fever (WD-MCF) when cross-species transmitted to a variety of susceptible species of the Artiodactyla order. Experimentally, WD-MCF can be reproduced in rabbits. WD-MCF is described as a combination of lymphoproliferation and degenerative lesions in virtually all organs and caused by unknown mechanisms. Recently, we demonstrated that WD-MCF is associated with the proliferation of CD8(+) cells supporting a latent type of infection in lymphoid tissues. Here, we investigated the macroscopic distribution of AlHV-1 infection using ex vivo bioluminescence imaging in rabbit to determine whether it correlates with the distribution of lesions in lymphoid and non-lymphoid organs. To reach that goal, a recombinant AlHV-1 strain was produced by insertion of a luciferase expression cassette (luc) in an intergenic region. In vitro, the reconstituted AlHV-1 luc(+) strain replicated comparably to the parental strain and luciferase activity was detected by bioluminescence imaging. In vivo, rabbits infected with the AlHV-1 luc(+) strain developed WD-MCF comparably to the parental wild-type strain with hyperthermia and increase of both CD8(+) T cells frequencies and viral genomic charge over time in peripheral blood mononuclear cells and in lymph nodes at time of euthanasia. Bioluminescent imaging revealed that AlHV-1 infection could be detected ex vivo in lymphoid organs but also in lung, liver and kidney during WD-MCF, demonstrating that AlHV-1 infection is prevalent in tissue lesions. Finally, we show that the infiltrating mononuclear leukocytes in non-lymphoid organs are mainly CD8(+) T cells and that latency is predominant during WD-MCF. [less ▲]
