    Notes: Identification of priorities for nursing research in Spain: a Delphi study Aim. The aim of this work was to identify priorities for nursing research in Spain. The Co-ordination and Development of Nursing Research Centre (Investén-isciii group) carried out the study using the Delphi technique during the period April 1998 to January 1999. Methods. Study subjects were professionals involved in different nursing activities. From 1250 eligible professionals initially contacted, 452 (38%) responded in round 1 and 258 (57%) in round 2. But only 189 filled out correctly the questionnaires from both rounds of data collection (overall response rate was 21·6%). Results. The participants identified priorities related to continuity and co-ordination of nursing care, quality of nursing care, impact of invasive techniques and treatments on the quality of life of patients, needs of the primary care givers, quality of life among elders, satisfaction of customers and needs of terminal patients and their families.

    Notes: Myxococcus xanthus, a member of the Proteobacteria delta-class, has two independent recA genes, recA1 and recA2, but only recA2 is DNA damage-inducible. The lexA gene has been isolated from M. xanthus by PCR amplification with oligonucleotides designed after sequence identification by tblastn analysis of its genome at the Cereon Microbial Sequence Database. The M. xanthus purified LexA protein is shown to bind specifically to the consensus sequence CTRHAMRYBYGTTCAGS present upstream of lexA and recA2. A degenerate copy of this motif but with important differences can be identified in the region upstream of the recA1 gene. A knock-out lexA(Def) mutant that has been generated does not differ significantly from wild type in morphology, growth rate, light-induced carotenogenesis or development. Using transcriptional lacZ fusions and quantitative RT-PCR analysis, it has been demonstrated that expression of both lexA and recA2 genes is constitutive in the lexA(Def) mutant, whereas the transcription of the DNA damage non-inducible recA1 gene is not affected in this strain. recN and ssb, whose expression in Escherichia coli are LexA-regulated, are induced by DNA damage in the M. xanthus lexA(Def) mutant. These data reveal the existence of different regulatory mechanisms for DNA damage-inducible genes in bacteria belonging to different phyla.

    Notes: In this work, we have investigated by DSC the structural relaxation of amorphous polymethyl(α-n-alkyl)acrylates in which it is possible to change the length of the alkyl chain. We have evaluated the Narayanaswamy parameter, x, which controls the relative contribution of temperature and of structure to the relaxation time, the apparent activation energy, Δh*, and the nonexponentiality parameter, β, of the stretched exponential response function. The results suggest that x increases while Δh* decreases and β remains constant as the length of the side chain increases. This allows us to comment on the effect of chemical modification on the relaxation kinetics. © 1998 John Wiley & Sons, Inc. J Polym Sci B: Polym Phys 36: 583-593, 1998
