    Notes: Summary. Dietary assessments and biochemical indices including plasma zinc and copper were determined in pregnant vegetarian and non-vegetarian Gujerati women in India at 28 weeks gestation, and the results were contrasted with those of a comparable group of Gujerati pregnant women living in Harrow. Even though the dietary intake of energy, protein and zinc was significantly lower in the Indian vegetarian Gujerati group when compared to the equivalent group in Harrow, the birthweights of the babies delivered at term were similar. The intake of zinc in the diet of the Gujerati Indian vegetarian and non-vegetarian groups was only one quarter of the US recommended intake during pregnancy and was approximately one half in the Harrow Indian groups. Even so, the plasma concentrations of zinc were similar in all dietary groups in either India or Harrow. The albumin content in the plasma of both the Gujerati Indian vegetarian and non-vegetarian was significantly reduced when compared to the equivalent Harrow dietary groups. The plasma concentrations of both calcium and sodium were significantly correlated with the albumin concentration but not with the plasma content of zinc. Copper levels were elevated to the normal range in both dietary groups of the Gujerati and were similar to the concentrations found in the Harrow groups.

    The relation between plasma urate and placental bed vascular adaptation to pregnancy (1986)

    Notes: Summary. Placental bed biopsies were obtained at caesarean section from 34 women. Their plasma urate was directly related to maximum mean arterial pressure and inversely to adjusted birthweight; but it was related most closely to the histological appearances of the spiral arteries in the placental bed. Nine women had physiological changes in the spiral arteries: their mean urate (233, SD 28·9 μmol/l) was significantly (P 〈0·00l) lower than the mean urate in those who did not have adequate physiological changes (339, SD 90·3 μmo1/l) or that in the nine women who had atherosis (397, SD 153·2 μmol/l). Raised plasma urate appears to be better related to maternal vascular pathology than to the clinical condition or infant birthweight.

    The relation of birthweight to histological appearances in vessels of the placental bed (1986)

    Notes: Summary. Biopsy of the placental bed was attempted at caesarean section in 109 patients: 77 consecutive and 32 selected because of the maternal or fetal condition. Forty-seven (44%) of these biopsies were from the placental bed and contained spiral arteries suitable for comment. Histological examination separated the patients into four groups: comprising 11 whose vessels showed normal physiological changes, 20 who showed inadequate physiological change, 12 with acute atherosis, and four with a mixed pattern. There was no relation between these changes and maternal age, parity, race or smoking habit, but no physiological change and atherosis were more common in association with maternal hypertension. Mean adjusted birthweight was greatest in those with physiological changes, less in those without physiological changes or the mixed pattern, and least in those with atherosis. The four patients in the mixed group did not have any unifying clinical characteristics.

    THE DETERMINATION OF A REFERENCE RANGE FOR URINARY OESTROGEN EXCRETION IN LATE PREGNANCY (1980)

    Notes: A reference range for urinary oestrogen excretion between 28 and 40 weeks has been produced by analysis of 18 870 estimations. The data were transformed logarithmically to give a Gaussian distribution on which parametric analysis was performed: non-parametric analysis was carried out on the untransformed data : the results of both analyses were compatible. Multiple pregnancies tended to have levels above the 50th centile, light-for-dates fetuses below the 50th centile. Antepartum haemorrhage showed no difference from the general reference range. Intrauterine death was preceded by a level below the 5th centile if the estimation was carried out less than one week before the fetus died.

    FETAL ELECTROENCEPHALOGRAPHY USING A NEW, FLEXIBLE ELECTRODE (1981)

    Notes: A single flexible active electrode for monitoring the fetal electroencephalogram (FEEG), has been designed specifically for use in routine obstetrics. It does not require penetration of or adherence to the fetal scalp, and it is reusable. The equipment's performance has been tested in 20 normal labours. The recordings obtained were not contaminated by the fetal electrocardiogram and were relatively free from artefact so that minimal filtering of the signal was required. No FEEG signal was obtained if the electrode was applied to breech presentations. The trace obtained from a healthy fetus was comparable with that recorded after delivery.

    Implementation of differential phase contrast Lorentz microscopy on a conventional transmission electron microscope (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 64 (1988), S. 6011-6013

    Notes: Differential phase contrast (DPC) Lorentz microscopy is a powerful technique for investigating magnetization distributions within magnetic thin films. Previously this imaging technique has only been used on microscopes with nonstandard electron optical configurations because of two conflicting requirements: (1) The electron beam must be focused to a very fine probe on the specimen to obtain a high spatial resolution. (2) The specimen cannot be in the magnetic field of the objective lens, as this would destroy the magnetic domain structures of interest. This paper will describe the implementation of the technique on a conventional microscope, a JEOL JEM 2000 FX fitted with an ASID 20 scanning attachment, which satisfies these two requirements. We have modified the controls for the lenses and deflection coils in the microscope to allow an electron probe of less than 40 nm to be formed using the three condenser lenses, with the objective lens off. A position sensitive quadrant detector, required for DPC imaging, is mounted on a sliding O-ring below the projector lens and can be moved in for DPC work or out for standard microscope operation. Attached to the microscope is a digital image acquisition system based on an IBM PC AT. This system is used to acquire signals from the four quadrants of the detector simultaneously. The signals are then mixed digitally to produce the DPC images and an incoherent bright-field image. These images can be further processed to produce vector maps of the in-plane magnetization distributions within the sample. The spatial resolution of 40 nm is less than that of the VG HB501 STEM vacuum generators (VG) HB501 scanning transmission electron microscope (STEM) previously used for DPC imaging. This is due to the larger emitting area of the LaB6 filament compared to the field emission gun of the VG. The LaB6 has a much lower brightness than the FEG and this necessitates long image acquisition times. DPC images and the corresponding vector map from a NiFe film will be shown to demonstrate the technique.

    Fetal urinary tract obstruction: is active intervention before delivery indicated? (1983)

    Notes: Summary. Obstruction of the urinary tract was diagnosed by ultrasound in four fetuses at 16—30 weeks: three of these diagnoses were confirmed after delivery; the fourth fetus had multicystic kidneys with hydroureter and hydronephrosis but no obstruction. The fetus with obstruction diagnosed at 16 weeks was terminated: it had lung hypoplasia with the prune-belly syndrome. The other two fetuses with obstruction were diagnosed at 25 and 34 weeks; the urinary tracts of both were drained for 5–14 days with reduction of distension. Both were born alive but that diagnosed at 25 weeks died of lung hypoplasia, the other survived, required nephrectomy and at the age of 3 is small but developing normally. Fetal urinary tract obstruction may prevent normal development of the lungs, be associated with other anomalies which cannot be diagnosed before delivery and retard infant development in survivors. Drainage of the dilated urinary tract does not harm the fetus or mother but has not been shown to improve neonatal survival or infant development.
