- The use of imprinted polymers for selective solid-phase extraction of local anaesthetics from human plasma was investigated. Methacrylic acid-ethylene glycol dimethacrylate based MIPs were developed by the alternative template approach using a structural analogue, pentycaine, as the template. The influence of the type and concentration of detergent in the buffer on selective and non-specific binding was investigated. Tween 20, Triton X-100 and Brij 35 were found to eliminate non-specific adsorption and leave selective imprint-onalyte binding essentially unaffected. Efficient pre-concert ration of ropivacaine and bupivacaine from plasma samples, both off-line prior to GC and in-line with LC-MS-MS, was demonstrated.

- We study linear PDE with constant coefficients. The constant rank condition on a system of linear PDEs with constant coefficients is often used in the theory of compensated compactness. While this is a purely linear algebraic condition, the nonlinear algebra concept of primary decomposition is another important tool for studying such system of PDEs. In this paper we investigate the connection between these two concepts. From the nonlinear analysis point of view, we make some progress in the study of weak lower semicontinuity of integral functionals defined on sequences of PDE constrained fields, when the PDEs do not have constant rank.

- A Gram- negative rod with a single polar flagellum was isolated from a freshwater reservoir used for household purposes in Boane District, near Maputo, Mozambique, and designated as strain DB1T. Growth was observed at 30???42 ??C (optimum, 30???37 ??C) and with 0.5???1.5 % NaCl. Whole- genome-, rpoD- and 16S rRNA- based phylogenies revealed this isolate to be distant from other Pseudomonas species with Pseudomonas resinovorans, Pseudomonas furukawaii and Pseudomonas lalkuanensis being the closest relatives. Phenotypic analyses of strain DB1T showed marked differences with respect to type strains P. resinovorans CCUG 2473T, P. lalkuanensis CCUG 73691T, P. furukawaii CCUG 75672T and Pseudomonas otiditis CCUG 55592T. Taken together, our results indicate that strain DB1T is a representative of a novel species within the genus Pseudomonas for which the name Pseudomonas boanensis is proposed. The type strain is DB1T (=CCUG 62977T=CECT 30359T).
