    Notes: Abstract Love wave dispersion in various semi-infinite media consisting of inhomogeneous layers is discussed. The phase and group velocities are computed when shear wave velocity and density in each inhomogeneous layer are varying exponentially with depth. At the beginning one or two inhomogeneous layers over a homogeneous semi-infinite medium are considered. The dispersion results for these structures are compared with those for their approximations with homogeneous layers. Comparisons show that differences of phase and group velocities for the original models from those for their approximated models (i) increase with the increase of wave number and (ii) are larger for group velocity than for phase velocity. The difference is approximately proportional to the rate of change of parameters in the layers. Finally, dispersion curves are obtained for model IP3MC, which consists of many inhomogeneous and homogeneous layers over a homogeneous semi-infinite medium. The results are compared with the observed group velocity data across the Indian Peninsula.

    Women's perceptions of decision-making about hysterectomy (2004)

    Notes: Objective  To explore women's views of decision-making relating to hysterectomy.Design  Structured questionnaire and in-depth interview surveys.Setting  A teaching hospital and a district general hospital in northeast Scotland.Sample  Women scheduled for hysterectomy for benign menstrual problems.Methods  Pre-operative questionnaires were sent to a consecutive sample of women booked for hysterectomy. A purposive sample was interviewed post-operatively.Main outcome measures  Women's experiences of, and satisfaction with, information provision, communication and decision-making processes; the relationship between views of decision-making processes and decisions made.Results  One hundred and four women (66%) returned questionnaires. Most responded positively to structured questions about the process by which the decision to have a hysterectomy was reached. Almost all (97%) reported satisfaction with the decision made. Twenty women were interviewed post-operatively. A number, including some who had responded positively on the questionnaire, described aspects of the decision-making process that were suboptimal. Women's perceptions of the decision-making process, including the way their doctors communicated with them, did impinge on their views of the course of action selected. Some women had residual doubts about the appropriateness of hysterectomy.Conclusions  In a significant minority of women, there are important shortcomings in current patterns of information provision and communication relating to decision-making. These are unlikely to be picked up by conventional structured patient feedback surveys. Further efforts are required to ensure that women are adequately informed and involved in decisions about gynaecological treatments.

    EFFECT OF SOME PROSTAGLANDIN SYNTHESIS INHIBITORS ON THE ANTINOCICEPTIVE ACTION OF MORPHINE IN ALBINO RATS (1978)

    Notes: 1. Five prostaglandin synthesis inhibitors, indomethacin, diclofenac, mefenamic acid, ibufen and paracetamol, were found to inhibit the antinociceptive action of morphine without affecting the antinociceptive response of an equi-analgesic dose of prostaglandin E12. Diclofenac was found to be the most potent and longest acting, whereas paracetamol was the least potent and shortest acting. Indomethacin, mefenamic acid and ibufen occupied an intermediate position, both in potency and duration of action.3. The results suggest that prostaglandins may be involved in the antinociceptive action of morphine in albino rats.

    Potentiation of antinociceptive action of morphine by prostaglandin E1 in albino rats (1975)

    Notes: 1. Prostaglandin E1 (0·4 mg/kg, i.p.) significantly potentiated the antinociceptive action of morphine in albino rats.2. This potentiation was significantly inhibited by pretreatment with reserpine, p-chlorophenylalanine or methysergide but not by α-methyl-p-yrosine, phentolamine or propranolol.3. The results suggest that the potentiation of morphine by prostaglandin E1 is mediated by serotonin, since it is inhibited by pharmacological agents known to reduce central turnover of serotonin receptors.

    A randomised controlled trial of intravenous versus inhalational analgesia during outpatient oocyte recovery (2000)

    Notes: To compare the efficacy and acceptability of conventional intravenous sedation with patient-controlled inhalational isodesox, 57 women undergoing outpatient oocyte recovery were randomly allocated to receive isodesox by face mask, while 55 women were given intravenous fentanyl and midazolam. Women's satisfaction with pain relief, peroperative pain, clouding of memory and the surgeons' assessment of operating conditions were evaluated. Thirty-eight women in the inhalation group (67%) and 41 (75%) women in the intravenous group were ‘very satisfied’ with their analgesia (p = 0.41). The mean (SD) pain score in women given isodesox was 46.8 (34.7), while in the intravenous group it was 34.1 (21.3) (p = 0.02). Oxygen saturation levels 〈 94% were recorded in one woman using isodesox and in 16 (29%) women given intravenous analgesia. Despite higher pain scores, in comparison with the conventional analgesia, patient-controlled isodesox offers a safer method of pain relief with comparable satisfaction rates.

    PROSTAGLANDINS: ANTINOCICEPTIVE EFFECT OF PROSTAGLANDIN E1 IN THE RAT (1977)

    Notes: 1. The antinociceptive effect of prostaglandins E1, E2 and F2α was studied in albino rats. Though all three prostaglandins produced similar degrees of sedation, only prostaglandin E1 (PGE1) produced a dose-related antinociceptive activity.2. The antinociceptive activities of equi-analgesic doses of morphine (7.5 mg/kg, i.p.) and PGE1 (2.0 mg/kg, i.p.) were inhibited to almost similar extents after pretreatment with drugs known to reduce central turnover of serotonin receptors, namely reserpine, fenclonine (p-chlorophenylalanine), methysergide and 5,6-dihydroxytryptamine.3. Prostaglandin F2α (2.0 mg/kg, i.p.) significantly inhibited the antinociceptive effects of both morphine and PGE1.4. The prostaglandin synthesis inhibitors, indomethacin and diclofenac, significantly inhibited morphine analgesia.5. Probenecid markedly prolonged the duration of antinociceptive effect of morphine and the duration of PGE1-induced potentiation of subanalgesic dose of morphine.6. The results suggest that, in albino rats, PGE1-induced antinociceptive activity is serotonin mediated and that morphine analgesia is not only mediated through serotonin but also through prostaglandins (PGE1?) and 5-hydroxyindole acetic acid, the serotonin metabolite.

    Multiphonon hopping conduction in nonconventional chromium-doped Bi3Pb1Sr3Ca3Cu4−nCrnOx (n=0.025–0.2) glasses with nanocrystalline particles and clusters (2000)

    Notes: Transport properties of Cr containing multicomponent oxide glasses Bi3Pb1Sr3Ca3Cu4−nCrnOx (n=0.025, 0.05, 0.1, and 0.2) dispersed with nanocrystalline particles (5–20 nm depending on the values of n) have been reported in the temperature range of 250–450 K. Conductivity of this glass-nanocrystal composite system shows little decrease with increasing Cr content. Above θD/2 (θD is the Debye temperature), conductivity data can be analyzed with small polaron hopping models. Interestingly, unlike undoped Bi4Sr3Ca3Cu4Ox (or Bi-4334) glasses [showing nonadiabatic small polaron hopping (SPH) conduction at T〉θD/2], the Cr doped glasses supports adiabatic SPH conduction mechanism above θD/2 indicating change of glass network structure due to partial substitution of Cu by Cr. But below this temperature Mott's or Greaves' variable range hopping models can be consistently used to fit the experimental conductivity data only with larger (compared to the usual transition metal oxide glasses) values of the density of states at the Fermi level N(EF). The most probable transport mechanism for the entire range of temperature and glass compositions is concluded to be due to multiphonon tunneling of large polarons between the nanoclusters present in the glasses which is also in sharp contrast to the behavior of the undoped (Bi-4334) glass. All the glass samples (except n≥0.2) are found to become superconductors by annealing at higher temperatures. © 2000 American Institute of Physics.
