Interruptions de grossesse dans le canton de Vaud en 2007

En 2007, un total de 1439 interruptions de grossesse ont été pratiquées dans le canton de Vaud, dont 89% concernaient des femmes domiciliées dans le canton. Rapporté à la population féminine en âge de procréer (15-49 ans), le taux d'interruption de grossesse est estimé à 7,6 pour mille (15-44 ans : 9,4 pour mille). Le taux d'interruptions de grossesses pour 1000 résidentes âgée de 15 à 49 ans marque une légère progression, passant de 6,8 pour mille en 2004 à 7,6 pour mille en 2007. Un écart important se maintient entre les femmes de nationalité étrangère (2007 : 13,1pour mille) et les Suissesses (4,6 pour mille). Dans les deux groupes, néanmoins, l'augmentation des interruptions de grossesse parmi les adolescentes (15-19 ans), observée au cours des trois dernières années, s'est interrompue en 2007. Le ratio des interruptions de grossesse par rapport aux nombre de naissances vivantes (exprimé en %) marque une très légère progression depuis 2003, passant de 15.2 à 16.7. Comme lors des années précédentes, on n'observe pas d'évolution particulière au niveau de l'âge gestationnel au moment de l'interruption. Dans leur très grande majorité, les interruptions de grossesse sont pratiquées avant la douzième semaine suivant l'arrêt des règles. En outre, l'âge gestationnel ne varie quasiment pas selon l'âge et la nationalité. Le pourcentage d'interruptions de grossesse par voie médicamenteuse continue d'augmenter. Il est passé de 31% en 2005 à 41% en 2007. Cette valeur reste encore nettement inférieure à la moyenne suisse (56%). Le recours à la méthode médicamenteuse demeure fortement associé au niveau de formation de la patiente (formation supérieure) et au type d'établissement dans lequel l'intervention est pratiquée. La probabilité d'une intervention médicamenteuse est ainsi trois fois plus élevée dans un hôpital régional qu'au CHUV. On observe peu d'évolution au niveau des caractéristiques sociodémographiques et des caractéristiques de la carrière reproductive. Le pourcentage de femmes ayant déjà interrompu une grossesse par le passé demeure élevé (31 %) en particulier dans certains groupes de nationalité (Afrique, Amérique du Sud). On note également, parmi les femmes ayant déjà eu un/des enfant/s, qu'un laps de temps relativement court sépare l'interruption de grossesse du dernier accouchement : 20% ont recouru à l'interruption de grossesse dans l'année ou dans l'année précédant l'interruption de grossesse.

Metabolic role of aquaglyceroporin 9 in astrocytes

Aim: Aquaglyceroporin-9 (AQP9) is a member of the Aquaporin channel family involved in water flux through plasma membranes and exhibits the distinctive feature of also being permeable to glycerol and monocarboxylates. AQP9 is detected in astrocytes and catecholaminergic neurons.1 However, the presence of AQP9 in the brain is now debated after a recent publication claiming that AQP9 is not expressed in the brain.2 Based on our results,3 we have evidence of the presence of AQP9 in the brain and we further hypothesize that AQP9 plays a functional role in brain energy metabolism. Methods: The presence of AQP9 in brain of OF1 mice was studied by RT-PCR and immunohistochemistry. To address the role of AQP9 in brain, we used commercial siRNA against AQP9 to knockdown its expression in 2 cultures of astrocytes from two distinct sources (from differentiated stem cells4 and primary astrocyte cultures). After assessment of the decrease of AQP9, glycerol uptake was measured using [H3]-glycerol. Then, modifications of the astrocytic energy metabolism was evaluated by measurement of glucose consumption, lactate release5 and evaluation of the mitochondrial activity by MTT staining. Results: AQP9 is expressed in astrocytes of OF1 mouse brain (mRNA and protein levels). We also showed that AQP9 mRNA and protein are present in cultured astrocytes. Four days after AQP9 siRNA application, the level of expression is significantly decreased by 76% compared to control. Astrocytes with AQP9 knockdown exhibit a 23% decrease of glycerol uptake, showing that AQP9 is a glycerol channel in cultured astrocytes. In parallel, astrocytes with AQP9 knockdown have a 155% increase of their glucose consumption without modifications of lactate release. Moreover, considering the observed glucose consumption increase and the absence of proliferation induction, the significant MTT activity increase (113%) suggests an increase of oxidative metabolism in astrocytes with AQP9 knockdown. Discussion: The involvement of AQP9 in astrocyte energy metabolism adds a new function for this channel in the brain. The determination of the role of AQP9 in astrocytes provides a new perspective on the controversial expression of AQP9 in brain. We also suggest that AQP9 may have a complementary role to monocarboxylate transporters in the regulation of brain energy metabolism.

Cation distribution and magnetization of BaFe12-2xCoxSnxO19 (x=0.9,1.28) single crystals

The distribution of Sn4+ cations within the five crystallographic sites of the magnetoplumbite (M) ‐like compound BaFe12−2xCoxSnxO19 has been analyzed using single‐crystal x‐ray‐diffraction data. The species Fe3+ and Co2+ cannot be distinguished using x rays because of their very similar atomic numbers; however, the calculation of the apparent valencies for the different sites allows an insight into the Co2+ cation segregation. The use of previous data from neutron powder diffraction allows a precise picture of the cation distribution, which indicates a pronounced site selectivity for both Sn4+ and Co2+ cations. The Sn4+ cations prefer the 4f2 sites and to a much lower extent the 12k sites, while they do not enter the octahedral 2a sites at all. Co2+ cations are distributed among tetrahedral and octahedral sites displaying a clear preference for the tetrahedral 4f1 sites. Magnetic measurements indicate that the compound still exhibits uniaxial anisotropy with the easy direction parallel to the c axis. Nevertheless, the magnetic structure shows a considerable degree of noncolinearity. A strong reduction of the magnetic anisotropy regarding that of the undoped compound is also detected.

Cedar-Iowa River Rail Transit Project Feasibility Study, November 9, 2006

Five Seasons Transportation & Parking (FSTP) and the Johnson County Council of Governments (JCCOG) are interested in evaluating the feasibility of prospective passenger rail service(s) that would operate over existing trackage of the Cedar Rapids and Iowa City Railway Company (CRANDIC), seen below left, and/or the Iowa Interstate Railroad System (IAIS), seen below right, connecting Cedar Rapids, Iowa City and the Amana Colonies. To perform the study, FSTP and JCCOG selected R.L. Banks & Associates, Inc. (RLBA) as Prime Contractors, HNTB Corporation (HNTB) and Snyder & Associates, Inc. (Snyder) as Subcontractors, hereafter Consultant Team. Both railroads participated in the study and contributed time and resources, as did many local government and civic organizations. The purpose of the study is to determine whether it is feasible to establish regularly scheduled passenger rail service and/or special event excursion rail service, in conjunction with the Five Seasons Transit system, Iowa City Transit, East Central Iowa Transit, Coralville Transit and the University of Iowa CAMBUS.

Iowa 86 from Iowa 9 to 700 feet South of 110th Street Dickinson County, Iowa, May 2011

The Transportation Equity Act of the 21st Century (TEA-21) (23 CFR) mandated environmental streamlining in order to improve transportation project delivery without compromising environmental protection. In accordance with TEA-21, the environmental review process for this project has been documented as a Streamlined Environmental Assessment (EA). This document addresses only those resources or features that apply to the project. This allowed study and discussion of resources present in the study area, rather than expend effort on resources that were either not present or not impacted. Although not all resources are discussed in the EA, they were considered during the planning process and are documented in the Streamlined Resource Summary, shown in Appendix A. The following table shows the resources considered during the environmental review for this project. The first column with a check means the resource is present in the project area. The second column with a check means the impact to the resource warrants more discussion in this document. The other listed resources have been reviewed and are included in the Streamlined Resource Summary.
