    Notes: Background : Symptom relief, through adherence to appropriate maintenance therapy, is the sole objective of treatment for patients with endoscopy-negative gastro-oesophageal reflux disease.Aim : To compare the efficacy of ‘on-demand’ treatment with esomeprazole 20 mg vs. continuous treatment with lansoprazole 15 mg daily in patients with endoscopy-negative gastro-oesophageal reflux disease.Methods : Endoscopy-negative gastro-oesophageal reflux disease patients who achieved complete resolution of heartburn after short-term (2–4 weeks) treatment with esomeprazole 20 mg (n = 774) were randomized to receive either esomeprazole 20 mg on-demand (n =311) or lansoprazole 15 mg continuous daily treatment (n = 311) for 6 months.Results : Significantly more patients were willing to continue taking esomeprazole on-demand than lansoprazole continuous therapy after 6 months (93% vs. 88%; P = 0.02). This superior outcome was achieved despite patients on esomeprazole requiring medication only 38% as often as those on lansoprazole, leading to direct cost savings of more than one-third (36%). Furthermore, patients receiving esomeprazole 20 mg on-demand were more satisfied with their treatment after 1 month compared with patients taking lansoprazole 15 mg continuously.Conclusions : In patients with endoscopy-negative gastro-oesophageal reflux disease, esomeprazole 20 mg on-demand is more acceptable to patients and is an economically more effective treatment than lansoprazole 15 mg continuously.

    Notes: [Auszug] DURING the nineteenth century, the discovery and study of 'lost civilizations' gave great impetus to the development of archaeology. The surviving traces of such civilizations - whether in the Mycenaean and Minoan palaces of the Aegean, the frontier defences of the Roman Empire, the pyramids of the ...

    Notes: Abstract The host-selection behavior of three species of grasshopper feeding on creosote bush,Larrea tridentata, in southern California was investigated. The species wereBootettix argentatus, which is monophagous;Ligurotettix coquilletti, oligophagous; andCibolacris parviceps, polyphagous. The monophagous species is stimulated to bite by nordihydroguaiaretic acid (NDGA), a compound that is characteristic of the host plant and that may comprise up to 10% of the dry weight of the leaf. Host specificity ofB. argentatus is enhanced by deterrent responses to compounds present in the surface waxes of all non-host-plant species. Both the oligophagous and polyphagous species are deterred by NDGA at naturally occurring concentrations. Their association withLarrea is probably based on tolerance of the plant chemicals rather than on dependence on specific chemicals. Factors other than the chemistry of the plant probably also contribute to the specificity ofB. argentatus andL. coquilletti.

    Notes: Abstract: High-spin states in neutron-rich Dy isotopes, populated in deep-inelastic processes produced by the interaction of 234 MeV 37Cl ions with a 160Gd target, have been studied using the highly sensitive EUROBALL IV gamma-ray detector array. The previously known level schemes for 159,160,161,162Dy have been extended to significantly higher spin ( ? 30?) and the i 13/2 band crossing in 159Dy has been observed for the first time. The experimental results are discussed within the framework of cranked shell model and projected shell model calculations with particular reference to the observed delayed band crossing in 162Dy.

    Notes: Abstract Factors inducing outbreaks of spider mites (Acari: Tetranychidae) following use of pyrethroid insecticides are reviewed. Differentials in direct toxicity between spider mites and phytoseiid (Acari: Phytoseiidae) predators provide one explanation. Wide variation exists between pyrethroids in their direct toxicity toTetranychus urticae. The acaricidal action of pyrethroids is largely controlled by the amount of irritancy or repellency induced by the respective chemicals. Laboratory assays for repellency reflect field results. Repellent activity induces spider-mite dispersal to either recolonise plants free of residues or leave the treated habitat. Pyrethroids may also affect reproduction and development rates. Residual activity is likely to vary, so limiting any general theory of spider-mite responses to pyrethroids. Variable responses to pyrethroids, strain variation and development of behavioural resistance also add complications to understanding outbreaks. Future research needs are identified.
