OBJECTIVE: This study was conducted to assess retrospectively the clinical tolerance of SD treated plasma and to compare it to other labile blood products (red blood cell and platelet concentrates). METHODS: Adverse events (AEs) related to the use of blood products at the Blood Transfusion Center (BTC) are routinely collected through a formalised system of hemovigilance. All AEs reported are entered into a safety data base which was used for the study. All AEs reported during a one-year period to the BTC were retrospectively re-assessed and descriptive statistics calculated. RESULTS: 5064 units of SD treated plasma were transfused to 894 recipients during the study period at the occasion of 1553 transfusions. No AE associated to SD treatment plasma was reported during that period. In contrast, during the same period, 485 AEs associated with the use of red blood cell concentrates (RBCC) were reported in 251 patients at the occasion of 262 transfusions. 2.1% (251/11,748) of the patients transfused with RBCC experienced one or more AEs. The incidence of AEs per unit transfused was 1.3% (485/37,332), and 2.4% (485/20,460) of RBCC transfusions were associated with one or more AEs. 142 AEs associated with the use of platelet concentrate (PC) were observed in 69 patients at the occasion of 73 transfusions. 4.2% (69/1645) of patients transfused with PC experienced one or more AEs. The incidence of AEs per unit transfused was 1.1% (142/12,772), and 2.8% (142/5034) of PC transfusions were associated with one or more AEs. All reported AEs were classified and non serious. The most frequently observed AEs were fever, chills and rashes which accounted for roughly 64% of all reported AEs. CONCLUSION: As for the overall clinical tolerance of red cell and platelet concentrates, the results of this study are in complete agreement with the published literature. The study also confirms the extremely good tolerability of SD treated plasma in comparison with other labile blood products. [less ▲]

We describe the development of a multipoint nonparametric quantitative trait loci mapping method based on the Wilcoxon rank-sum test applicable to outbred half-sib pedigrees. The method has been evaluated on a simulated dataset and its efficiency compared with interval mapping by using regression. It was shown that the rank-based approach is slightly inferior to regression when the residual variance is homoscedastic normal; however, in three out of four other scenarios envisaged, i.e., residual variance heteroscedastic normal, homoscedastic skewed, and homoscedastic positively kurtosed, the latter outperforms the former one. Both methods were applied to a real data set analyzing the effect of bovine chromosome 6 on milk yield and composition by using a 125-cM map comprising 15 microsatellites and a granddaughter design counting 1158 Holstein-Friesian sires.

Town and country planning also involves care of individual "territories" as well as those of groups and societies. After a brief recapitulation of motivations for and objections to taking into account citizen's expectations concerning "territorial" planning this paper illustrates the situation in Wallonia. Three types of planning are illustrated : pure theoretical planning, participatory planning and empathic planning. Finally, the paper underlies the challenges facing public services, education and research wich must be addressed if empathic and effective planning is to be implemented. [less ▲]

Shear-induced order of aqueous micellar solutions of a poly(tert-butylstyrene)-b-poly(sodium methacrylate) diblock (c ) 2.5-15 w/v %) has been investigated by small-angle X-ray scattering. Data collected from a Couette cell in both radial and tangential geometries agree with a crystalline ordering of micelles in close packed hexagonal layers perpendicular to the velocity gradient, when c is in the 5-10 w/v % range. The measured interlayer distance is indeed very close to the value expected for a closepacked structure. The experimental data are consistent with a zigzag motion of adjacent planes upon shear. Shear-induced order is, however, restricted to a narrow concentration range just above the concentration for the sol-gel transition. This domain is thought to correspond to a regime where relative layer translation modes are allowed whereas mutual rotation is hindered. [less ▲]
