Evidence for intimate interconnections between the three major systems of cell communication, the nervous, endocrine and immune systems, has opened important novel research perspectives. Neuroimmune-endocrine interactions are now established as crucial factors for the control of body development and homeostasis. In distant species and invertebrates, the foundations of both the neuroendocrine system and innate immunity were coexisting until now without any apparent problem. Some 400 millions years ago, in a relatively short period after agnathan fishes (e.g., hagfish and lamprey), adaptive immunity emerged in the first gnathostomes, cartilaginous fishes (e.g., shark and ray). Somatic recombination machinery characterizes adaptive immunity and is responsible for the random generation of the huge diversity of immune receptors able to recognize infectious antigens. The emergence of this novel form of immune defenses exerted a so potent pressure that structures and mechanisms developed along the paths of lymphocyte traffic to impose immunological self-tolerance, that is, the inability of the immune system to attack the host organism. Together with the generation of diversity and memory, self-tolerance constitutes a fundamental property of the immune system. The progressive rise in the level of immune diversity and complexity also explains why self-tolerance failures (i.e., organ-specific autoimmune diseases) were increasingly detected during evolution, the maximum being currently observed in the human species. The first thymus appeared in cartilaginous fishes (chondrichthyes), concomitantly with the emergence of rudimental forms of adaptive immunity. Though some forms of tolerance induction already takes place in primary hemopoietic sites (fetal liver and bone marrow), antigen-dependent B-cell tolerance is primarily due to an absence of T-cell help. Among all lymphoid structures, the thymus is the only organ specialized in the establishment of central self-tolerance. The thymus crucially stands at the crossroad between the immune and neuroendocrine systems. In this organ responsible for thymopoiesis—T-cell generation—(Kong et al., 1998), the neuroendocrine system regulates the process of T-cell differentiation from the very early stages. In addition, T lymphocytes undergo inside the thymus a complex educative process that establishes central T-cell self-tolerance of neuroendocrine principles (Geenen et al., 1992; Martens et al., 1996). Within the thymus, a confrontation permanently occurs between previously established neuroendocrine principles and a recent system equipped with recombination machinery promoting stochastic generation of response diversity. Contrary to a previous assumption, the thymus functions throughout life (Poulin et al., 1999; Geenen et al., 2003) and plays a fundamental role in the recovery of a competent T-cell repertoire after intensive chemotherapy or during highly active antiretroviral therapy (Mackall et al., 1995; Douek et al., 1998).

The 4M-µpump project attempts to breach the gap between traditional mechanics and micro mechanics and this in two ways. The first one consists in producing a general set of rules suitable for the miniaturisation of well-known macromachines. The second one consists in developing this fundamental aspect of the research through the design and realization of an implantable pump dedicated to the administration of medication agents inside the human body. The project thus touches upon the field of design, manufacturing, metrology and assembly of mini components as well as the study of minimotors. [less ▲]

The pore texture of carbon materials obtained from evaporative drying and pyrolysis of resorcinol-formaldehyde aqueous gels is controlled by the initial pH of the precursors solution. In order to produce transition metal-containing carbons with tailored texture, various metallic salts were dissolved in the precursors solution. When necessary, a complexing agent (HEDTA or DTPA) was added to render the metal ions soluble. Ni, Fe and I'd loaded carbon xerogels were synthesized and their pore texture was studied after evaporative drying and after pyrolysis. The carbon texture was also studied with regard to the nature of the metal and the amount of complexing agent. The solubilization of transition metal salts in the resorcinol-formaldehyde aqueous solution does not prevent the texture regulation, even though this texture control is influenced: the limits of the pH interval leading to micro mesoporous carbon materials can slightly differ when a metal salt and/or a complexing agent are added. The pH range shift depends mainly on the amount and nature of the complexing agent, but also slightly on the nature of the metal ion. Nevertheless, the metal particles obtained are rather big (diameter > 15 nm). For catalytic applications, the metal dispersion must be enhanced, especially in the case of expensive metals.

This paper presents an extension of the energy momentum conserving algorithm, usually developed for hyperelastic constitutive models, to the hypoelastic constitutive models. For such a material no potential can be defined, and thus the conservation of the energy is ensured only if the elastic work of the deformation can be restored by the scheme. We propose a new expression of internal forces at the element level which is shown to verify this property. We also demonstrate that the work of plastic deformation is positive and consistent with the material model. Finally several numerical applications are presented.

The methanol dissociative adsorption on Pt(1 0 0) at low potentials in the hydrogen region is studied using nonlinear vibrational sum-frequency generation (SFG) spectroscopy. It is shown that adsorbed hydrogen atoms effectively block atop sites at the surface. In the hydrogen potential region, CO produced by the methanol dissociation adsorbs at step-edges and in bridge sites on terraces as shown by the characteristic stretching frequencies observed for adsorbed CO.
