There were fewer deliveries before 33 weeks in the cerclage group (83 (13%) compared with 110 (17%), P=0.03) and this difference reflected deliveries characterised by features of cervical incompetence (painless cervical dilatation and prelabour rupture of the membranes). There was a corresponding difference in very low birthweight deliveries (63 (10%) compared with 86 (13%), P=0.05). The difference in the overall rate of miscarriage, stillbirth or neonatal death (55 (9%) compared with 68 (11%)) was less marked and was not statistically significant. The use of cervical cerclage was associated with increased medical intervention and a doubling of the risk of puerperal pyrexia.Conclusions These results suggest that the operation had an important beneficial effect in 1 in 25 cases in the trial (95% confidence interval (CI) 1 in 12 to 1 in 300 sutures). Its use is associated with increased medical intervention and puerperal pyrexia. Nevertheless, this trial suggests that, on balance, cervical cerclage should be offered to women at high risk, such as those with a history of three or more pregnancies ending before 37 weeks gestation.Type of Medium: Electronic ResourceURL: -

ISSN: 1471-0528Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Summary. A case of extremely severe birth asphyxia is reported. In spite of successful resuscitation the arterial pH was still only 6.6 at the age of 1 h. Assessment at 3 years 10 months revealed that the child was not only completely normal, but was of superior intelligence. This case demonstrates the advisability of maintaining an optimistic approach even when very severe fetal acidosis is detected around the time of birth.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Crystals of α-[(4'-methoxyphenyl)methylene]-4-nitro-benzeneacetonitrile exhibit powder second-harmonic generation (SHG) efficiencies under 1.06 μm irradiation several times that of 2-methyl-4-nitroaniline. We have identified three distinct, solution-grown polymorphs which show marked variation in SHG efficiency. Controlled transformation between these polymorphs can be made either solvent assisted or thermally. One polymorph shows a 25-fold increase in SHG efficiency when the irradiation wavelength is changed to 1.32 μm while the others show a small or no increase.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1471-0528Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Summary. In the 13-month period between June 1985 and July 1986, 27 children were found to be HIV positive in the Princess Margaret Hospital in Nassau. Nineteen of the children had clinical AIDS, four were in the prodromal phase and four were symptom free. The clinical course of these infants is presented. Of the 18 mothers 16 were screened and were all seropositive and asymptomatic. They remained healthy in spite of subsequent pregnancies in nine of them (56%) during a follow-up period of between 13 and 65 months (mean 40 months). Fifteen of the 18 mothers were Haitian but only three had other risk factors, throwing doubt on the value of selective screening in Afro-Caribbean countries.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1471-0528Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Objective To assess the usefulness of a leaflet distributed to women before colposcopy designed to reduce their anxiety and psychosexual by providing information.Design Prospective randomised study.Setting Colposcopy clinic of a large district general hospital.Sample Two hundred consecutive women undergoing colposcopy for the first time for a cervical cytological abnormality of severity no greater than moderate dyskaryosis.Methods Women were randomised into one of two groups (leaflet or control). Those in the leaflet group were sent an information leaflet prior to attending the clinic. In the colposcopy clinic all the women completed a Statenrait Anxiety Inventory (StAVTrAI) and a modified psychosexual questionnaire before undergoing colposcopy. This was repeated at the six-month follow up visit. Women in the leaflet group also completed a further questionnaire on the leaflet.Main outcome measures Differences of anxiety and psychosexual scores between leaflet and control groups.Results The leaflet was well received. There were no statistical differences in StAI and TrAI scores between the study group and the control group at either visit, although in the whole study population StAI and TrAI scores were reduced at the second visit. The leaflet group had significantly more psychosexual problems but by the second visit, the scores had improved and the two groups were similar. When the mean differences in anxiety and psychosexual scores at the initial and second visits were compared between the groups, the reduction in negative sexual feelings and deterioration of TrAI scores experienced by the leaflet group was significant.Conclusions This study suggests that the provision of sending an information leaflet prior to colposcopy is not beneficial in isolation. Other approaches need to be considered.Type of Medium: Electronic ResourceURL: -

ISSN: 1747-6593Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Energy, Environment Protection, Nuclear Power EngineeringNotes: Bray Weir on the River Thames near Maidenhead was refurbished during the summers of 1993 and 1994. The existing structure, which had become unsound and unsafe to operate, was replaced by nine vertical-lift (or buck) gates. Construction works within a cofferdam and utilizing floating plant were undertaken in two phases. Following demolition of the existing weir, a network of reinforced concrete beams was supported on new driven piled foundations. Twin leaf gates slide in guides and span between new steel A-frames, and are lifted by pairs of threaded spindles rotated by actuators operating through gearboxes. Fine flow control is achieved by allowing overtopping of the upper leaves of the gates. Following commissioning, operational difficulties resulting from seal vibration and excessive friction on the spindles necessitated design modifications.This paper outlines a brief history of the site, the design options considered, the contract strategy employed, and includes a description of the construction phase and subsequent postcommissioning aspects.Type of Medium: Electronic ResourceURL: -

Published 1994Staff ViewISSN: 1365-246XSource: Blackwell Publishing Journal Backfiles 1879-2005Topics: GeosciencesNotes: An analysis of Satellite Laser Ranging (SLR) data to the LAGEOS satellite has yielded improved estimates of the horizontal motion for a subset of 34 tracking sites within the global tracking network. The analysis, called SL8.3, utilized data acquired between 1980 January and 1993 June by the global network composed of 71 sites. The solution design provides for the simultaneous estimation of site positions and their velocities within a pre-defined kinematic frame. The solution is statistically rigorous and retains the full correlation information content. Least-squares estimates of relative poles of rotation, which are used to model the motion of one plate relative to another, were made based on the SLR estimated velocities for sites known to be well away from deformation zones. The resulting SLR-based relative rotation poles differ slightly from those of NUVEL-1, but in general, indicate that the magnitude of the SLR implied velocities is slower than those implied by NUVEL-1, consistent with the 4–5 per cent slowing in relative spherical rates noted in earlier comparisons. Spherical rates between sites in western North America support models of extension in the Basin and Range Province and the rotation of the Sierra Nevada microplate. An analysis of the spherical rates crossing the North Atlantic shows that SL8.3 estimated extension between North America-Eurasia sites is generally smaller than those implied by NUVEL-1: meanwhile SL8.3 rates between North America-Africa sites are in better agreement with NUVEL-1, although they are not so well determined. The maintenance and ongoing monitoring of global SLR site kinematics provides a well-defined global reference which will aid in combination global kinematic solutions where information from other technologies are merged (e.g. Very Long Baseline Interferometry and Global Positioning System) and in providing the context for densification studies of regional kinematics derived from terrestrial and Global Positioning System observations.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1365-2958Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyMedicineNotes: The relative LD50 values in two test Lepidoptera of Bacillus thuringiensis subspecies kurstaki HD1, which contains three crylA protoxin genes, was the same as a plasmid-cured derivative or a Bacillus cereus transcipient containing only one of the three genes. Differential rates of transcription of these genes in the original strain could account, at least partly, for this result. Strains containing only the single protoxin gene (crylA(b)) produced inclusions when grown at 25°C but not 32°C, despite transcription of this gene at both temperatures. The instability of the crylA(b) protoxin was not found in the parental B. thuringiensis subsp. kurstaki HD1 strain grown at either temperature, however, so kurstaki HD1 strains with multiple protoxin genes must produce some stabilizing factor, perhaps another protoxin.The cryl protoxins contain a highly conserved carboxyl half which is proteolytically removed upon conversion to toxin. All of the protoxin cysteines are present in protease-sensitive regions and they are oxidized in inclusions. Most of the disulphides appear to be essential for specificity since their reduction in the crylA(b) protoxin resulted in loss of selectivity for one of the test insects. This lack of specificity was also found for this protoxin produced by an Escherichia coli clone, probably because of the reducing conditions in these cells. Specificity was restored by reoxidation of the pure protoxin, by removal of the carboxyl half of oxidized protoxin with trypsin, or by subcloning of the toxin portion. The oxidized form of protoxins must be important for specificity, for the formation of crystalline inclusions, and probably for interactions required for the stabilization of some protoxins.Type of Medium: Electronic ResourceURL: -
