    Notes: Summary. The vagina is a common source of non-sporing anaerobic bacteria which may be the cause of postoperative infection after hysterectomy. A single vaginal pessary containing 1 g of metronidazole inserted the night before abdominal hysterectomy reduced the mean duration of postoperative pyrexia from 15·4 to 8·3 h (P〈0·05).

    A retrospective review of cervical cytology in women developing invasive squamous cell carcinoma (1983)

    Notes: Summary. The records of 93 women who presented with invasive squamous cell carcinoma were searched for evidence of cervical cytology during the years preceding this diagnosis; a search was also made through the files of local laboratories and contact was made with general practitioners and relevant hospital departments. Only 26 (28%) of these 93 women had had a cervical smear at any time before the diagnosis of invasive cancer, and only 11 (12%) had had regular cytological surveillance. Fifteen (60%) had had a smear taken and reported as negative within the previous 5 years, six (6%) within the previous year. Eleven of these 15 slides were obtained for review: three were regarded as positive and three more were re-classed as too scanty for conclusive assessment. In nine of the 67 women who had never had a smear, a gynaecological or obstetric examination was known to have been performed or indicated within the previous 5 years, thereby representing a missed opportunity for screening. In three patients cytological abnormalities had been reported within the previous 3 years but no action had been taken.

    YBa2Cu3O7-δ single crystals revisited: Scanning probe data on very pure samples grown in BaZrO3 crucibles (1998)

    Notes: 2 Cu3O7-δ (YBCO) single crystals grown in BaZrO3 crucibles by scanning and friction force microscopy (SFM, FFM) as well as by scanning tunneling microscopy (STM) and angle resolved X-ray photo-electron spectroscopy (ARXPS). By STM and SFM, clean stepped terraces are observed on as-grown crystals. Friction contrast, however, implies the presence of different materials, presumably traces of flux. After oxidation of the YBCO crystals, particles of 10 to 100 nm in size appear on the surface. Their number per unit area increases with time when the crystal is stored in air. Complementary information on such aged YBCO surfaces is provided by ARXPS. These data reveal 3 nm of mainly BaCO3 and CuO on top of the YBCO matrix and suggest a very slow aging rate of the crystals, which is 20 times slower than for epitaxial thin films. The superconducting energy gap has been determined on fresh crystals by scanning tunneling spectroscopy (STS) at 4.6 K as 2Δ≈30 meV. By spatially resolved tunneling spectroscopy the vortex lattice in a magnetic field of 4 T has been imaged. The inter-vortex distance amounts to 20±2 nm.

    Behavior of trifluralin in aquatic model ecosystems (1980)
    Springer
    Bulletin of environmental contamination and toxicology 24 (1980), S. 134-141

    Notes: Conclusions These data illustrate the variation that can be obtained when using different model ecosystem designs in studying the behavior of pesticides in the aquatic ecosystem. These differences were probably related to the rapid metabolism and degradation of soil-incorporated trifluralin in the first experiment and to the continuous input of trifluralin in the second experiment. A very important difference between the two ecosystems was the toxic effect of trifluralin on the algae and fish during the second experiment. We believe that the risks of trifluralin in the aquatic ecosystem are greatest when there is a continuous input of tribluralin. With an occasional soil-incorporated input, the degradation processes would minimize this risk.

    Stone algebra extensions with bounded dense sets (1997)

    Notes: Abstract. Stone algebras have been characterized by Chen and Grätzer in terms of triples $ (B, D, \varphi) $ , where D is a distributive lattice with 1, B is a Boolean algebra, and $ \varphi $ is a bounded lattice homomorphism from B into the lattice of filters of D. If D is bounded, the construction of these characterizing triples is much simpler, since the homomorphism $ \varphi $ can be replaced by one from B into D itself. The triple construction leads to natural embeddings of a Stone algebra into ones with bounded dense set. These embeddings correspond to a complete sublattice of the distributive lattice of lattice congruences of S. In addition, the largest embedding is a reflector to the subcategory of Stone algebras with bounded dense sets and morphisms preserving the zero of the dense set.

    In vivo apparent affinity and efficacy estimates for μ opiates in a rat tail-withdrawal assay (1998)

    Notes: Abstract Experiments in a rat tail-withdrawal assay tested the hypothesis that the magnitude and pattern of antagonism of μ opiate agonists by the insurmountable μ opioid antagonist clocinnamox are inversely related to agonist efficacy. In addition, these experiments examined whether this antagonism could be quantified to yield apparent affinity and efficacy estimates for the pharmacological characterization of five opiate agonists. Etonitazene, etorphine, morphine, buprenorphine, and GPA 1657 produced dose-dependent increases in tail-withdrawal latency until 100% maximum possible effect (%MPE) was obtained. Morphine required a higher dose of clocinnamox for a 50% reduction in maximal antinociceptive effect than did buprenorphine or GPA 1657. In contrast, no dose of clocinnamox tested decreased the%MPE for etonitazene or etorphine. These data suggest a rank order of relative efficacy of etonitazene ≥ etorphine 〉 morphine ≥ GPA 1657 ≥ buprenorphine. Similarly, numerical analysis of these data yielded the following apparent affinity and efficacy estimates: etonitazene (0.38 mg/kg, 128); etorphine (0.68 mg/kg, 125); morphine (50 mg/kg, 38), GPA 1657 (6.6, 39); and buprenorphine (0.042 mg/kg, 2.2). These data illustrate that in vivo affinity and efficacy estimates for a number of agonists are remarkably similar across different methods of analysis and are useful for drug classification.

    Notes: Abstract  The purpose of these experiments was to examine the relationship of agonist relative efficacy to the pattern of tolerance and cross-tolerance to the morphine-like stimulus effects of three opioid agonists. Rats were trained to discriminate 3.2 mg/kg morphine from saline under fixed-ratio 15 schedule of food reinforcement. Morphine, nalbuphine, and fentanyl produced dose-dependent increases in morphine-like stimulus effects and decreases in response rates. Repeated treatment with 20 mg/kg per day morphine increased the ED50 for stimulus control by fentanyl, morphine, or nalbuphine two-, four-, or 40-fold, respectively. Repeated treatment with 64 mg/kg per day nalbuphine increased the ED50 for stimulus control for morphine by two-fold, but lower or higher treatment doses had no significant effect. Treatment with 100 mg/kg per day nalbuphine increased the ED50 for nalbuphine by six-fold. Repeated treatment with 0.22 mg/kg per day fentanyl increased the ED50 for stimulus control by fentanyl or morphine by approximately two-fold. Comparisons among treatment conditions suggested that magnitude of tolerance to morphine-like stimulus effects did not vary as an inverse function of the relative efficacy of the agonist used for repeated treatment. Rather repeated morphine and fentanyl treatments produced comparable tolerance, whereas repeated nalbuphine treatment did not evoke substantial tolerance. Comparisons within treatment conditions, however, suggested that magnitude of tolerance may vary inversely with relative efficacy of the agonist tested for morphine-like stimulus effects. During treatment with morphine or fentanyl, greater tolerance was observed to the morphine-like stimulus effects of the lower efficacy agonist relative to the higher efficacy agonist.
