The erythrocyte, as an oxygen carrier, is submitted to areas where oxidative stress is important. The maintenance of the structure and fluidity of its membrane is essential to its function. Indeed, oxygen must diffuse through the membrane and the deformability of the cell is essential to its progression through capillaries. The structure and, as a consequence, the fluidity of the membrane influence these properties. The red blood cell presents antioxydant capacities, but in some cases, free radical production is increased and exceeds antiradical defences leading to irreversible defects of the membrane, and, as a consequence, of its function. Horse erythrocyte seems to be more sensitive to oxidative stress than other species and resulting hemorheological changes could have tissular and organic consequences. [less ▲]

Accelerated failure time models with a shared random component are described, and are used to evaluate the effect of explanatory factors and different transplant centres on survival times following kidney transplantation. Different combinations of the distribution of the random effects and baseline hazard function are considered and the fit of such models to the transplant data is critically assessed. A mixture model that combines short- and long-term components of a hazard function is then developed, which provides a more flexible model for the hazard function. The model can incorporate different explanatory variables and random effects in each component. The model is straightforward to fit using standard statistical software, and is shown to be a good fit to the transplant data. [less ▲]

In order to predict delayed settlements of heavy structures, the authors decided to use the elasto-viscoplastic model of Dafalias-Kaliakin. To identify the parameters of the constitutive equations, they use above all the data of a new in-situ test, the Diflupress L.D. designed to approach the creep behavior of soil. In a first section, the principle of the model is presented. Then, the important parameters of the model are identified, mostly from in-situ test data since the laboratory tests data are not numerous and reliable. Finally, a study of sensitivity on the parameters which influence the viscoplastic response of the model is made. [less ▲]

RATIONALE: Repeated administrations of ethanol induce a progressive and enduring increase in its locomotor stimulant effects, a phenomenon termed behavioral sensitization that has not been systematically characterized. OBJECTIVE: The aim of the present studies was to characterize the development and expression of ethanol sensitization in female Swiss mice by examining (1) the doses of ethanol that induce behavioral sensitization, (2) the doses of acute ethanol challenges that are necessary to express behavioral sensitization, (3) the effects of the intervals between administrations, and (4) the context dependency of ethanol sensitization. MATERIALS AND METHODS: Mice were i.p. injected for 8 days with various ethanol doses, and locomotion was recorded for 5 min. Two days after the last sensitization session, ethanol sensitization was tested in 30-min test sessions. RESULTS: Mice repeatedly injected with 2.5 g/kg ethanol showed a progressive (200-300%) increase in locomotor activity. In response to a 2.5 g/kg ethanol challenge, the mice repeatedly treated with doses above 1.5 g/kg showed a significant sensitization. Following the induction of sensitization with the maximally effective sensitizing dose (2.5 g/kg), mice showed greater activation after challenges with 1.5, 2.0, 2.5, and 3.0 g/kg ethanol. The intervals (24, 48, or 96 h) between ethanol injections did not affect the induction or expression of sensitization. Finally, sensitization to 2.5 g/kg ethanol was expressed regardless of the context in which it was induced. CONCLUSIONS: Female Swiss mice develop a robust context-independent sensitization after repeated ethanol injections at all doses above 1.5 g/kg, including highly sedative doses such as 4 g/kg.

Numerical modelling of the lateral-torsional buckling of steel beams at elevated temperature has shown that the beam design curve from EN 1993-1-2 is over-conservative in the case of non-uniform bending. Based on the newly proposed methodology for cold design from the EN 1993-1-1, an improved proposal for the lateral-torsional buckling of unrestrained steel beams subjected to fire is presented in this paper that addresses the issue of the influence of the loading type, the steel grade, the pattern of the residual stresses (hot-rolled or welded sections) and the ratio h/b, between the depth h and the width b of the cross-section on the resistance of the beam, achieving better agreement with the numerical behaviour while maintaining safety. The proposal is found to be safe and accurate through an extensive comparison with the results of FEM numerical simulations of more than 5000 beams. A statistical study of the results is performed, showing the accuracy of the improved proposal presented in this paper. (C) 2007 Elsevier Ltd. All rights reserved. [less ▲]
