Abstract Issue The national physical activity plan (NPAP) for Ireland originated from an interdepartmental, cross-disciplinary structure that was put in place to promote population (PA) levels. There is a documented gap between research, policy and practice which hinders this promotion of levels PA. Irish Physical Activity Research Collaboration (I-PARC) established play key role contributing t...

Mutants of wild-type Streptococcus pneumoniae IID553 with mutations in parC were obtained by selection with trovafloxacin, levofloxacin, norfloxacin, and ciprofloxacin. All of the parC mutants were cross-resistant to the selecting agents but were not resistant to gatifloxacin and sparfloxacin. On the other hand, gyrA mutants were isolated by selection with gatifloxacin and sparfloxacin. The gyr...

In this talk we present a number of problems for network design, planning and analysis and show how they can be addressed with different hybrid CP solutions. Clearly, this problem domain is of huge practical importance, but it also provides us with interesting, complex problem structures. CP directly competes with MILP and local search approaches to these problems, with best results often obtai...

Construction of the Japan Proton Accelerator Research Complex (J-PARC), which consists of a 400 MeV Linac, a 3 GeV Rapid Cycling Synchrotron (RCS), and a 50 GeV Main Ring (MR), commenced in 2001. J-PARC is a multipurpose accelerator complex. The RCS uses 1 MW proton beams to generate pulse neutrons that will be used for various research projects ranging from basic science to applied science at ...

To the Editor: In pneumococci, resistance to fluoroquinolones is associated with chromosomal mutations in the quinolone-resistance–determining regions (QRDR) of type II topoiso-merase enzymes, predominantly gyrA and parC. Several mutations have been described in these enzymes, but only a few have been shown by in vitro studies to confer resistance: S81F or Y, C, or I and E85K in gyrA; E474K in ...

Background/aims: T lymphocytes are present in increased numbers in the conjunctiva of patients with vernal keratoconjunctivitis (VKC) and their activation has a central role in the pathogenesis of the chronic allergic inflammatory reactions seen in VKC. The aims of this study were to examine the expression of three recently described potent T lymphocyte chemoattractants, PARC (pulmonary and act...

  Target modification and reduced drug accumulation are the main resistance mechanisms against fluoroquinolone antibiotics in Pseudomonas aeruginosa. We performed a genotypic characterization of three major Mex multidrug efflux pumps (MexAB-OprM, MexXY-OprM and MexCD-OprJ) in ciprofloxacin resistant clinical isolates of P. aeru­ginosa, collected from Tehran, Iran this was followed by sequencin...

Sir, A recent review by Smith et al.1 and associated correspondence2,3 raised important unresolved issues regarding which quinolones exert dual activity through gyrase and topoisomerase IV in Streptococcus pneumoniae. Dual action involves the substantial engagement of both enzyme killing pathways and is of particular interest in potentially limiting the emergence of resistance. Smith et al.3 co...

We examined the antimicrobial susceptibilities of 85 Neisseria gonorrhoeae isolates, classified according to the presence of amino acid substitutions in the GyrA and ParC proteins, to 12 fluoroquinolones and 7 other antibiotics. Sitafloxacin and HSR-903 showed excellent activity against N. gonorrhoeae, including strains with both GyrA and ParC substitutions. Among the strains with various GyrA ...
