Pour permettre à une femme enceinte de continuer à travailler en toute sécurité, l'OProma (ordonnance du Département fédéral de l'économie sur les activités dan- gereuses ou pénibles en cas de grossesse et de maternité) est entrée en vigueur en 2001. Cette loi concerne les employeurs, les médecins traitants, les gynécologues et les travailleuses enceintes et précise comment certains travaux, substances, ou micro- organismes peuvent faire courir un risque potentiel à la mère et à son enfant et comment ces risques doivent être évalués et traités. Le but de l'étude est d'évaluer, par le biais de questionnaires, l'état des connaissances des mesures légales de protection de la maternité au travail en général et plus spécifi- quement de l'OProma, chez 76 femmes enceintes suivies à la consultation d'obstétrique du CHUV (questionnaires administrés en face à face) et chez 87 gynécologues du CHUV et installés en Suisse romande (questionnaire on line). Les objectifs sont : déterminer la prévalence de la connaissance de ces dispositions légales, évaluer les facteurs person- nels pouvant influencer la connaissance de ces dernières, les raisons possibles du manque d'information et les mesures pouvant être prises pour améliorer cet état de fait. Concernant les femmes enceintes, 68% savent qu'il existe des mesures légales et 32% connaissent l'OProma, surtout par le biais de l'employeur et de l'entourage. L'unique facteur personnel significatif influençant la connaissance des mesures légales est le niveau de formation. Concernant les gynécologues, 95% savent qu'il existe des mesures légales et 47% connaissent l'existence de l'ordonnance, surtout dans le cadre de la formation continue. Les facteurs personnels significatifs sont l'âge et leurs années d'expérience pro- fessionnelle. Les deux populations trouvent que le manque d'information provient d'une méconnaissance de ces dispositions légales chez les employeurs. Les gynécologues re- connaissent aussi leurs lacunes et se sentent mal informés. Pour améliorer le manque d'information, les femmes demandent à en être informées par leur gynécologue. Les gy- nécologues désirent plus d'information et de formation sur la thématique. Il en ressort que les deux populations ont une bonne connaissance de l'existence de me- sures légales en général mais l'OProma spécifiquement est peu connue. Les gynécologues la connaissent mieux que les femmes enceintes, ce qui est loin d'être suffisant. Chez les femmes enceintes, le niveau de formation a été choisi dans cette étude comme indica- teur pour la classe sociale. L'appartenance à une classe sociale plus élevée induit une meilleure connaissance des mesures légales et de l'OProma. Chez les gynécologues, les médecins plus âgés et donc plus expérimentés connaissent mieux les mesures légales et l'OProma. Probablement, un médecin avec plus de pratique, la globalité de la patiente avec sa problématique sociale sera mieux prise en considération, en comparaison à un jeune médecin plus focalisé sur les problèmes somatiques. Il y a encore des efforts à faire concernant la formation des gynécologues et des em- ployeurs à propos de ce sujet. En effet, ces derniers se doivent d'assurer à la travailleuse enceinte une grossesse sans danger.

The main objective of this study was to evaluate the hydraulic performance of riprap spurs and weirs in controlling bank erosion at the Southern part of the Raccoon River upstream U.S. Highway 169 Bridge utilizing the commercially available model FESWMS and field monitoring. It was found based on a 2 year monitoring and numerical modeling that the design of structures was overall successful, including their spacing and stability. The riprap material incorporated into the structures was directly and favorably correlated to the flow transmission through the structure, or in other words, dictated the permeable nature of the structure. It was found that the permeable dikes and weirs chosen in this study created less volume of scour in the vicinity of the structure toes and thus have less risk comparatively to other impermeable structures to collapse. The fact that the structures permitted the transmission of flow through them it allowed fine sand particles to fill in the gaps of the rock interstices and thus cement and better stabilize the structures. During bank-full flows the maximum scour hole was recorded away from the structures toe and the scourhole size was directly related to the protrusion angle of the structure to the flow. It was concluded that the proposed structure inclination with respect to the main flow direction was appropriate since it provides maximum bank protection while creating the largest volume of local scour away from the structure and towards the center of the channel. Furthermore, the lowest potential for bank erosion also occurs with the present set-up design chosen by the IDOT. About 2 ft of new material was deposited in the area located between the structures for the period extending from the construction day to May 2007. Surveys obtained by sonar and the presence of vegetation indicate that new material has been added at the bank toes. Finally, the structures provided higher variability in bed topography forming resting pools, creating flow shade on the leeward side of the structure, and separation of bed substrate due to different flow conditions. Another notable environmental benefit to rock riprap weirs and dikes is the creation of resting pools, especially in year 2007 (2nd year of the project). The magnitude of these benefits to aquatic habitat has been found in the literature that is directly related to the induced scour-hole volume.

Needle-free procedures are very attractive ways to deliver vaccines because they diminish the risk of contamination and may reduce local reactions, pain or pain fear especially in young children with a consequence of increasing the vaccination coverage for the whole population. For this purpose, the possible development of a mucosal malaria vaccine was investigated. Intranasal immunization was performed in BALB/c mice using a well-studied Plasmodium berghei model antigen derived from the circumsporozoite protein with the modified heat-labile toxin of Escherichia coli (LTK63), which is devoid of any enzymatic activity compared to the wild type form. Here, we show that intranasal administration of the two compounds activates the T and B cell immune response locally and systemically. In addition, a total protection of mice is obtained upon a challenge with live sporozoites.

(Résumé de l'ouvrage) The book of Hebrews has often been the Cinderella of the New Testament, overlooked and marginalized; and yet it is one of the most interesting and theologically significant books in the New Testament. A Cloud of Witness examines the theology of the book in the light of its ancient historical context. There are chapters devoted to the structure of Hebrews, the person of Jesus Christ, Hebrews within the context of Second Temple Judaism and the Greco-Roman empire and the role of Hebrews in early Christian thought.

Airborne microbial products have been reported to promote immune responses that suppress asthma, yet how these beneficial effects take place remains controversial and poorly understood. We have found that pulmonary exposure with the bacterium Escherichia coli leads to a suppression of allergic airway inflammation, characterized by reduced airway-hyperresponsiveness, eosinophilia and cytokine production by T cells in the lung. This immune modulation was neither mediated by the induction of a Th1 response nor regulatory T cells; was dependent on TLR-4 but did not involve TLR-desensitization. Dendritic cell migration to the draining lymph nodes and subsequent activation of T cells was unaffected by prior exposure to E.coli indicating that the immunomodulation was limited to the lung environment. In non-treated control mice ovalbumin was primarily presented by airway CD11b+ CD11c+ DCs expressing high levels of MHC class II molecules whilst the DCs in E.coli-treated mice displayed a less activated phenotype and had impaired antigen presentation capacity. Consequently, in situ Th2 cytokine production by ovalbuminspecific effector T cells recruited to the airways was significantly reduced. The suppression of airways hyper responsiveness was mediated through the recruitment of IL-17-producing gd-T cells; however, the suppression of dendritic cells and T cells was mediated through a distinct mechanism that could not be overcome by the local administration of activated dendritic cells, or by the in vivo administration of TNF-alpha. Taken together, these data reveal a novel multi-component immunoregulatory pathway that acts to protect the airways from allergic inflammation.
