The bovine mastitis : from initiation to resolution The cure of a cow suffering from a bacterial mastitis relies on the balance between the eradication of the pathogen and the resolution of the inflammatory response, two processes that are essential to come back to a normal milk composition with low somatic cell count. The persistence of the inflammatory response, which main consequence is a reduction in milk yield, is a feature of chronic mastitis. This frequent disease depends on inappropriate host-pathogen interactions and is not yet well understood. This review resumes the main defence mechanisms of the bovine mammary gland, emphasizing the predominant roles played by the neutrophil, and brings some precisions on lipoxin implications in the resolution of inflammation. Reasons that may explain the persistence of the inflammatory reaction, a phenomenon found in the Staphylococcus aureus chronic mastitis, are also discussed. [less ▲]

Intracellular invasion of Staphyloccocus aureus in nonphagocytic cells Staphylococcus aureus often causes chronic diseases. It is now believed that recurrence of these infections could be related to the ability of S. aureus to invade and persist within nonphagocytic cells. Adherence to eucaryotic cells is crucial for S. aureus to invade and persist within invasion and depends on interactions between bacterial fibronectin-binding proteins, fibronectin and the host cell fibronectin receptor, integrin alpha(5)beta(1). It is currently established that fibronectin acts as a bridging molecule. Penetration of S. aureus in host cells requires also activation of protein tyrosine kinases that mediate signal transduction and actin polymerization leading to cytoskeletal rearrangements. After internalization, S. aureus either remains in membrane-bound vacuoles or appears free in the cytoplasm. After bacterial proliferation, S. aureus induces host cell apoptosis or persist inside cells as small colony variants, which represent a less virulent subpopulation of S. aureus that grows slower. Although numerous in vitro and in vivo studies have demonstrated the ability of S. aureus to invade nonphagocytic cells, additional experiments have to be realized to understand the relevance of intracellular localization in vivo.

The Kigali university medical centre (CHUK) lacks visibility on its activities for many years. Institution management as well understanding the institution as the corner stone of the Rwandese health system and reinforcement of its visibility are all health policy major issues. Nevertheless, to this point no such tool has been developed nor implemented. The objective is to assess the feasibility of the use of the thesaurus 3BT as data collection tool in a Rwandese health institution. In august 2005, the thesaurus 3BT (Belgian, bilingual, biclassified ICD-10/ICPC-2) adapted to the CHUK has been implemented. Main issues : encoding quality and thesaurus operationality. Qualitative analysis has been performed on 899 coding of which 16 empty. Low occurrences (! 0.2 %) of about 25 % of codings of clinical diagnosis show the need for using a thesaurus but also to upgrade it. Near 45 % of the empty codings could be fulfilled with a quick look to the original medical record. Some diagnoses are missing in the thesaurus 3BT. 66 % of which have similar concepts in the thesaurus although not identifiable by a lay person. Finally, a clinical data blind coding test by a doctor used to classifications and by a lay person used to code clinical diagnosis from medical records of the hospitalised patients shows an exact similarity in 70 % of the coding and a loss of coding precision in 20 %. No coding error has been identified at this time. In conclusion, operationality of the thesaurus is quite acceptable in this study. The thesaurus makes easy the coding of clinical diagnosis even by lay people. Quality of data is enough to be able to interpret the quantitative results of the coding process. This study has to be repeated on a wider basis. [less ▲]

Research activities are part of the cooperation model developed by the Cemubac. The foundation for the research is based on strengthening the capacity of health systems and services resulting in the improvement of care offered to communities. The research (quantitative and qualitative) has a high participatory dimension and was able to develop thanks to partnerships with professionals and beneficiaries. It relies heavily on the implication of national public staff trained specifically for this work and on long-term presence in the area. The work in Kivu has continued over the past fifteen years despite a deteriorating social, economic and security context. As an organism for acquiring knowledge, the Cemubac’s work in Kivu is primarily geared towards improving health services. [less ▲]

Successfully modelling flows over a spillway and on strongly vertically curved bottoms is a challenge for any depth-integrated model. This type of computation requires the use of axes properly inclined along the mean flow direction in the vertical plane and a modelling of curvature effects. The proposed generalized model per-forms such computations by means of suitable curvilinear coordinates in the vertical plane, leading to a fully integrated approach. This means that the flows in the upstream reservoir, on the spillway, in the stilling basin and in the downstream river reach are all handled in a single simulation. The velocity profile is generalized in comparison with the uniform one usually assumed in the classical shallow water equations. The pressure dis-tribution is modified as a function of the bottom curvature and is thus not purely hydrostatic. Representative test cases, as well as the application of the extended model to the design of a large hydraulic structure in Bel-gium, lead to satisfactory validation results. [less ▲]

In [Prog Theor Phys Suppl 49(3):173–196, 1999], Lecomte conjectured the existence of a natural and projectively equivariant quantization. In [math.DG/0208171, Submitted], Bordemann proved this existence using the framework of Thomas–Whitehead connections. In [Lett Math Phys 72(3):183–196, 2005], we gave a new proof of the same theorem thanks to the Cartan connections. After these works, there was no explicit formula for the quantization. In this paper, we give this formula using the formula in terms of Cartan connections given in [Lett Math Phys 72(3):183–196, 2005]. This explicit formula constitutes the generalization to any order of the formulae at second and third orders soon published by Bouarroudj in [Lett Math Phys 51(4):265–274, 2000] and [C R Acad Sci Paris Sér I Math 333(4):343–346, 2001].

This book describes the general guidelines for waste and landfill management, especially for developing countries. It contains four chapters. Ch. 1 describes waste management in developing countries (waste composition, production and harvesting modes; landfills characteristics; valorisation). Ch. 2 describes environmental aspects of waste management (biodegradation phenomenons; bioreactor-like landfill management; environmental impacts; investigation of biological activity of landfill in developing countries). Ch. 3 describes the general guidelines for controlled landfill (investigations for site location; landfill construction under wet and dry climates; landfill management and monitoring; financial aspects). Ch. 4 synthesizes the social and economical aspects of waste and landfill management and describes some best practices for harvesting, valorisation, and disposal of MSW) [less ▲]

The development, the establishment and the embryonic survival at early stages of gestation are depending on an intimate dialogue between the embryo and his mother. For the embryo part, it is especially the trophoblast, or the future placenta, which plays a key role in initializing pregnancy. The placenta emits many signals of various chemical natures ( steroids, prostaglandins, peptides, proteins), some of them, e. g. the interferon tau, determine the maintenance of the corpus luteum at the beginning of gestation. Until now, although having raised many speculations, the earliest of these signals were not identified in peripheral circulation. Consequently, they cannot be used as a pregnancy diagnosis or to indicate embryonic mortality. However, since the eighties, the specific proteins "associated with pregnancy", produced by the trophoblastic cells are used as tool for breeding management. Most of these molecules are present in peripheral circulation. In this review, we will describe the major mechanisms associated with the maternal recognition of the gestation and their possible applications as pregnancy diagnosis tool in the cow. [less ▲]
