[more ▼] A tendency to an increase in migration times was observed when different water-soluble vitamins were analysed repeatedly in pharmaceutical preparations by capillary electrophoresis. In order to better understand the origin of this effect, the influence of the vitamins and the excipients, such as cellulose derivatives, was investigated. These studies indicated that the increase in analyte migration times was most probably due to the adsorption of different kinds of constituents to the capillary wall. Different rinsing procedures were tested in order to eliminate these unfavourable effects. A rinse of the capillary with a 25 mM sodium dodecyl sulfate (SDS) solution in the running buffer between successive runs was found to be particularly effective when the analysis was performed by free solution capillary zone electrophoresis (CZE). When the vitamins were determined by micellar electrokinetic chromatography (MEKC) using SDS as surfactant, a short capillary rinse with the running buffer was sufficient to obtain reproducible migration times. The CZE and MEKC methods developed were validated and compared. Both methods could be applied to the determination of water-soluble vitamins in different multivitamin formulations.

[more ▼] It is well understood that energy rich polyatomic molecules do not dissociate promptly because the number, P, of their energy states far exceeds the number, N, of the decay channels. In the simplest RRK theory, the fraction N/P is the probability of dissociation. We discuss the distribution of the decay rates of maximal entropy and conclude that it is governed by at most N linearly independent constraints, N < P, or, more typically, N << P. This mathematical requirement already severely restricts the number of constraints. Beyond it however, on physical grounds, one constraint, or at most a few, may be dominant. We discuss why just one constraint, or a few but less than N, can be sufficient to describe the product state distribution.

[more ▼] Les services d’urgence sont régulièrement confrontés au problème d’encombrement à l’admission par une demande qui dépasse l’offre de soins. Il est essentiel de réguler le flux d’entrée par la mise en place d’un dispositif de tri. Ce mécanisme s’affine depuis une quinzaine d’années. Nous proposons un algorithme de tri (ELISA ou Echelle Liégeoise de l’Indice de Sévérité à l’Admission) qui vise à définir l’état d’urgence selon 5 niveaux depuis la catégorie U1 (urgence absolue) à U5 (urgence relative). Ces niveaux sont associés à un délai de contact médical (immédiat à 120 minutes) et à un trajet de soin correspondant (salle de déchoquage, secteur B ou brancard, secteur A ou ambulatoire, salle d’attente) réunissant ainsi des impératifs de temps et de lieu de prise en charge optimaux. Notre algorithme de tri montre une excellente fiabilité par la comparaison du niveau initial de la catégorisation au devenir du patient (soins intensifs, hospitalisation, et sortie du service).
