BACKGROUND: The incidence of syphilis is on the rise in many cities worldwide. Both the clinical and histopathological changes do not always fulfil the typical diagnostic criteria. Immunohistochemistry is available to identify and localize Treponema pallidum. Two main patterns of T. pallidum distribution were described in the skin, namely heavy intraepidermal infiltration and scattered pattern inside the lichenoid cell infiltrate. OBJECTIVE: To search for a third pattern consistent with dissemination of the disease. METHODS: Immunohistochemistry using an antispirochete (T. pallidum and Borrelia) antibody was used in all cases of syphilis submitted to our laboratory. In addition, deposits of immunoglobulins and complement indicative of immune complexes were searched for. RESULTS: According to the cases, T. pallidum was disclosed in a combination of three patterns. The previously described epidermal and lichenoid patterns were confirmed, and a third pattern predominating in a perivascular location throughout the dermis was clearly identified in primary syphilis. The microorganisms were abundant in extracellular and intracellular locations, particularly inside endothelial cells. No deposits of immunoglobulins and complement were disclosed. CONCLUSION: The perivascular cuff of T. pallidum throughout the dermis might be representative of the dissemination phase of T. pallidum. [less ▲]

A time-domain extension of the classical frequency-domain thin-shell approach is used for the finite-element analysis of a shielded pulse-current induction heater. The time-domain interface conditions at the shell surface are expressed in terms of the average (zero-order) instantaneous flux and current density vectors in the shell, as well as in terms of a limited number of higher-order components. The three-dimensional thin-shell model is validated by comparing the numerical results with measurements performed on the heating device at different working frequencies. [less ▲]

Abstract : Here, we aim to develop the conditions of possibility of a collective learning process for the forest ecosystem governance. We argue that stakeholders’ discussion and public debate should be intrinsically interconnected with the expertise of the soil-plant cycle. As Chris Argyris underlines, “[i]t is possible to develop knowledge, both valid and which can be “put into action” in everyday life” and which “provides an opportunity to test it in everyday life”. Primary forest is the most biologically diverse type of vegetation system and is characterized by a balance between biomass production and soil evolution. Soil, as the nutrient source, plays a crucial role in the forest productivity. Currently, only 21% of the world forests are indigenous. Human activities, through the “production paradox”, disrupt this homeostasis between the nutrient source and the vegetal production. The mobility of nutrients in the soil-plant system has to be taken into account for sustainable forest governance. Then, the knowledge of the relationship between soil and plant is a “proper way to compose, decompose, or recompose problem sets” and could also be a proper possibility of “controversy” that allows us to elaborate a collective and critical learning process which “entails an appreciation of complexity and an effort to integrate problems into a more comprehensive whole”. Finally, our governance hypothesis focuses on a critical environmental ethics which integrates both the common sense moral feelings involving stakeholders and the knowledge of causal relationship in a forest ecosystem (i.e. soil-plant cycle). This critical environmental ethics will be established on a “critical knowledge” as Jean Ladrière underlines it into his work on science and rationality. [less ▲]

BACKGROUND: Skin aging is a multifaceted process influenced by various factors affecting at variable degree at different body sites. This study focused on the aging process affecting dermal dendrocytes and the microvasculature. We also explored the effect of substance P released by capsaicin because this neuropeptide is known to affect the microvasculature environment. METHODS: The first part of the present study was undertaken in two groups of 35 men who were younger than 30 years and older than 65 years, respectively. A skin biopsy was taken from the intact skin of a thigh during orthopedic surgical intervention after road accident. The second part of the study was performed on 30 men aged 65-68 years. They applied once daily a 0.05% capsaicin gel and the vehicle in a randomized design on the volar forearms. A skin biopsy was taken at inclusion and after a 5-month treatment phase. Immunohistochemistry was performed using a panel of antibodies. Dermal cells were distinguished according to the presence of factor XIIIa, CD34 or thrombomodulin. Blood and lymphatic vessels were studied by Ulex europaeus agglutinin-1, human podoplanin, human vascular endothelial growth factor-C (H-VEGF-C) and alpha-actin immunoreactivities. RESULTS: In the study phase 1, a significant decrease in thrombomodulin-positive cells and vascularity were evidenced in the aged group. In the study phase 2, capsaicin appeared to boost the factor XIIIa-positive dendrocytes, the thrombomodulin-positive cells and the blood vessel network as well. CONCLUSIONS: Specific subsets of the dermal dendrocyte populations and the blood microvasculature appear affected by aging. Capsaicin may limit these aging effects. [less ▲]

Dans la littérature scientifique, il n’a pas été question d’une vraie contextualisation du Technology Assessment en Wallonie. Ce Courrier hebdomadaire tente de reconstituer le chemin qu’ont suivi les acteurs de l’innovation (tant du monde politique que scientifique ou industriel) depuis les années 1980 jusqu’à nos jours, et de mettre en avant les éléments qui constituent des obstacles ou des atouts pour une réflexion concrète et efficace sur le rôle d’un Technology Assessment dans la gouvernance wallonne des choix scientifiques et technologiques. Nous commencerons par retracer l’historique du TA en Wallonie, et nous décrirons les éléments qui ont mené à son institutionnalisation temporaire, en 1994, bien avant la création de l’IST flamand. Nous explorerons les raisons qui ont mené à un échec avant de nous livrer à un rappel historique et analytique du régime wallon de recherche et d’innovation, depuis les grandes réformes institutionnelles de 1988-1989. Nous tenterons ensuite de comprendre comment des pratiques et des institutions se stabilisent et créent un cadre commun pour l’action, mais aussi des obstacles au changement. Tant la réflexion entamée par le programme Prométhée (1998) que les initiatives de « réseaux d’entreprises » (grappes technologiques et clusters) ou encore les pôles de compétitivité (2005) ont profondément transformé le régime wallon de recherche et d’innovation. Ces évolutions sont intéressantes à suivre et à relier au Technology Assessment car, en tant qu’instrument politique, il est en charge de la gestion de l’interface entre le système politique et le système de recherche et d’innovation. En parallèle des transformations qui touchent au système wallon de recherche et d’innovation, nous pensons que les initiatives qui voient actuellement le jour au niveau politique reflètent peut-être une certaine évolution des mentalités, notamment pour ce qui touche au TA. Pour illustrer ce propos, il sera question à la fin de cet article d’une récente proposition de résolution, votée à l’unanimité en commission du Parlement wallon, et qui vise à doter le Conseil wallon de la politique scientifique d’une mission de Technology Assessment. Nous nous attacherons à mettre en perspective la construction d’un cadre d’analyse qui a récemment permis un alignement des acteurs autour de ce projet concret et nous conclurons en analysant cette initiative wallonne, dont le futur sera intimement lié aux développements consécutifs aux élections régionales de juin 2009.
