    Notes: Abstract When deciding an appropriate upper limit for pulse oxygen saturation (SpO2) in preterm infants the usefuleness of current data is limited by the fact that previous studies have examined a population of more mature infants and children or have applied various exclusion criteria which produce results unrepresentative of clinical practice. We tested the hypothesis of previous workers that maintaining the SpO2 below 98% would ensure an arterial oxygen tension (PaO2) less than 12 kPa. A total of 477 simultaneous measurements of PaO2 and SpO2 were made using Ohmeda Biox oximeters on 43 infants who were less than 33 weeks gestation and receiving supplementary oxygen. Of 435 measurements performed when the SpO2 was 97% or less, 26 (6%) had a PaO2 greater than 12 kPa. Further examination of the data showed that of 108 estimations performed when the SpO2 was less than 94%, none had a PaO2 greater than 12 kPa. Conclusion When using Ohmeda Biox pulse oximeters an upper limit of 97% for SaO2 is not effective in preventing hyperoxaemia; however, a limit of 93% is likely to maintain the PaO2 below 12 kPa.

    Notes: Abstract The preterm infant is deficient in vitamin A (retinol) and this has been implicated in the pathogenesis of chronic lung disease of prematurity. Conjunctival impression cytology (CIC) has been used in adults to assess retinol status. We aimed to assess the feasibility of performing CIC in the preterm infant and to determine the significance of abnormal CIC findings. CIC samples were collected during routine retinopathy screening, and classified as inadequate, normal, borderline normal or abnormal. Ninety preterm infants were studied. Seventy-four (82%) CIC specimens produced a positive yield, whereas 16 (18%) were inadequate. Of the 74 adequate samples, 61 (82%) were normal or borderline normal and 13 (18%) abnormal. Seventy-three CIC specimens were assessed by a second histopathologist with complete agreement on 64 (88%) samples and disagreement on 9 (12%) samples. Ten sets of conjunctival impressions, taken from both eyes, gave identical results in all adequate samples. Birth weight was significantly lower in this abnormal group. Four infants (32%) in the abnormal group required treatment for retinopathy compared to two (3%) in the normal/borderline normal group. (P 〈 0.01) Conclusion Conjunctival impression cytology is simple and reproducible technique which maybe easily applied to the preterm infant. Abnormal CIC is associated with retinopathy of prematurity requiring treatment.

    Outcome predictors in pregnant opiate and polydrug users (1999)
    Springer
    European journal of pediatrics 158 (1999), S. 748-749

    Notes: Abstract A retrospective case note study of 93 women was performed in order to assess the effect of maternal factors on neonatal outcome in a group of women attending a specialist clinic for pregnant drug users. There were no significant differences in outcome for chaotic drug users compared with non-chaotic drug users, or for cocaine users compared with non-cocaine using drug users. Women who reduced their methadone dose during pregnancy delivered babies of significantly higher birth weight than those whose methadone dose remained the same or increased (median 3027 g, range 1780–3629 g vs 2645 g, range 580–3720 g). Women who abused benzodiazepines during pregnancy produced babies of significantly lower birth weight than those women who did not use benzodiazepines (median 2100 g, range 580–3520 g vs 2767 g, range 1530–3720 g). Conclusion The results of this study give healthcare staff evidence to use in encouraging drug-using women to avoid benzodiazepines during pregnancy and to reduce their methadone dosage. The treatment received from a specialist clinic may mitigate against some of the other recognised effects of drug use during pregnancy.

    Biotin production under limiting growth conditions by Agrobacterium/Rhizobium HK4 transformed with a modified Escherichia coli bio operon (1999)

    Notes: E. coli biotin (bio) operon was modified to improve biotin production by host cells: (a) the divergently transcribed wild-type bio operon was re-organized into one transcriptional unit; (b) the wild-type bio promoter was replaced with a strong artificial (tac) promoter; (c) a potential stem loop structure between bioD and bioA was removed; and (d) the wild-type bioB ribosomal binding site (RBS) was replaced with an artificial RBS that resulted in improved bioB expression. The effects of the modifications on the bio operon were studied in E. coli by measuring biotin and dethiobiotin production, and bio gene expression with mini-cells and two-dimensional polyacrylamide gel electrophoresis. The modified E. coli bio operon was introduced into a broad host-range plasmid and used to transform Agrobacterium/Rhizobium HK4, which then produced 110 mg L−1 of biotin in a 2-L fermenter, growing on a defined medium with diaminononanoic acid as the starting material. Biotin production was not growth-phase dependent in this strain, and the rate of production remained high under limiting (maintenance) and zero growth conditions.

    Morphological effects and the diffusion of iodine in CdTe (1995)

    Notes: Abstract The morphology of undiffused and iodine-diffused CdTe slices and its effect on iodine concentration profiles is discussed. Such CdTe slices were analysed using defect etching, scanning electron microscopy (SEM), infrared microscopy and secondary ion mass spectrometry (SIMS). The results suggest that during diffusion a layer of an iodine compound forms in the surface region of the CdTe while, over a limited range further into the material, clusters of either this or a similar compound form at defect sites causing a high degree of crystal distortion.

    Andreev reflection of a beam of ballistic quasiparticle excitations incident on a static B-A phase interface in superfluid3He (1995)

    Notes: Abstract We have attempted to observe the Andreev reflection of a beam of ballistic quasiparticle excitations as it impinges on a static B-A phase interface. The beam is created, and the Andreev reflected component measured, by the quasiparticle equivalent of a black-body radiator. The A-phase is stabilized at low temperature and pressure by a magnetic field which is generated by a miniature superconducting solenoid, situated next to the radiator orifice and which provides the necessary 0.34 T field in a small, localized region. Preliminary results indicate that we can observe Andreev reflection both from the high-field distorted B-phase energy gap and from the larger equatorial A-phase energy gap.

    Persistent Precessing Texture-Trapped Domains in Low Temperature Superfluid 3He (1998)

    Notes: Abstract It has recently been discovered that at temperatures below about 0.2T C in superfluid 3 He-B, pulsed NMR excitation can generate a new coherently precessing spin state which can have a lifetime of tens of seconds. The free induction decay signal from this state has been called the persistent induction signal (PIS). The earlier observations of the PIS have found it to be highly irreproducible indicating a strong connection with the magnetic texture. Here we describe measurements of the PIS within an experimental cell which was designed to fix the textural configuration of the superfluid. The resulting PIS signals are now far more reproducible allowing a more systematic study of the behaviour which we present here. Furthermore in the latest cell the decay of this signal has been observed to last for up to 4 minutes at the lowest temperatures. While the precessing state is readily accessible to observation, at these temperatures it is a very delicate object and we can immediately see the influence of background radiation on the time evolution of the decay.
