    Pelvic floor damage and childbirth: a neurophysiological study (1990)
    Oxford, UK : Blackwell Publishing Ltd
    BJOG 97 (1990), S. 0

    Notizen: Summary. Ninety six nulliparous women were investigated to establish whether childbirth causes damage to the striated muscles and nerve supply of the pelvic floor. The techniques used were concentric needle electromyography (EMG), pudendal nerve conduction tests and assessment of pelvic floor contraction using a perineometer. There was EMG evidence of re-innervation in the pelvic floor muscles after vaginal delivery in 80% of those studied. Women who had a long active second stage of labour and heavier babies showed the most EMG evidence of nerve damage. Forceps delivery and perineal tears did not affect the degree of nerve damage seen. We conclude that vaginal delivery causes partial denervation of the pelvic floor (with consequent re-innervation) in most women having their first baby. In a few this is severe and is associated with urinary and faecal incontinence. For some it is likely to be the first step along a path leading to prolapse and/or stress incontinence.

    Photofluxonic detection: A new mechanism for infrared detection in superconducting thin films (1990)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 57 (1990), S. 2847-2849

    ISSN: 1077-3118

    Thema: Physik
    Notizen: A new model is proposed in which a photon of energy E=hf is absorbed by a superconducting film to create a pair of equal and opposite fluxons (or vortices), each with quantized flux Φ0=h/2e. An applied current sweeps these fluxons to opposite edges of the film, causing a voltage pulse with time-integrated magnitude Φ0, and leading to a time-averaged voltage responsivity Rv = Φ0/E = 1/(2ef). This is directly analogous to photoconductive detection in a semiconductor via creation of electron-hole pairs. Data on an ultrathin granular NbN film are presented which indicate a responsivity of 6000 V/W in red light, in agreement with the model. This is promising for the development of a sensitive, high-speed infrared detector using thin films of either low or high Tc superconductors.

    Mosaic acral keratosis (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Clinical and experimental dermatology 15 (1990), S. 0 
    Details
    ISSN: 1365-2230
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: We describe two patients with acral keratosis with a striking mosaic or jigsaw-puzzle pattern of keratotic papules on the dorsal aspects of the feet and adjacent parts of the legs. Both patients also showed mild diffuse palmoplantar keratosis and clavus-like lesions over the interphalangeal joints of the toes; one patient also had keratotic papules on the hands and hyperkeratotic plaques over the knees. The differential diagnosis of acral keratoses, including several recently described forms, is briefly discussed.

    A large tumour from the gray snapper, Lutjanus griseus (L.) (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish diseases 13 (1990), S. 0

    Notizen: Abstract. Using a panel of special stains employed in human histopathology and immunohistology, the authors diagnosed a tumour from the common gray snapper, Lutjanus griseus (L.), as a myoma, Only a few such tumours have been previously reported from fishes. Gray snapper are readily available and may provide a model for basic studies on this, as well as other, types of tumour.

    X-RAY PHOTOGRAMMETRY OF ARTIFICIAL JOINTS (1990)
    Oxford, UK : Blackwell Publishing Ltd
    The @photogrammetric record 13 (1990), S. 0 
    Details
    ISSN: 1477-9730
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Architektur, Bauingenieurwesen, Vermessung
    Notizen: X-ray photogrammetry has the potential to make a significant contribution to clinical orthopaedic practice. The features of X-ray photogrammetry as it can be applied in the clinical setting are reviewed, together with some of the analytical methods of three dimensional reconstruction. A major effort in orthopaedics involves the further improvement in the durability of artificial hip joints, whose ultimate life is usually limited by loosening of the components within the bone. Current methods of assessment are described and a review presented of X-ray photogrammetry of the hip. It is believed that a proposed system at Oxford combines the best features of earlier methods. Some possible developments of X-ray photogrammetry in orthopaedics are suggested.

    Isle of Wight Water Metering Trial (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Water and environment journal 4 (1990), S. 0 
    Details
    ISSN: 1747-6593

    Thema: Energietechnik
    Notizen: The Isle of Wight water metering trial is one of twelve being conducted in England and Wales. The paper describes the consultations that were undertaken, leading up to the design of a metered tariff to meet local requirements. The trial was designed to investigate the problems which a large-scale implementation of water metering would have and specifically examines meters placed either within a property or laid at the property boundary. The particular problems that arose are discussed, and the problems associated with electrical earthing are briefly described.The trial, which commenced in the autumn of 1988, involves installing a water meter in all 53 000 Island properties. Southern Water Services Ltd engaged Southern Projects (a sister company within the Southern Water Group) to organize the installation work.The paper outlines the principal activities of how the trial was planned and executed, with some thoughts on the problems arising during the installation phase.

    Sites of [3H]taurine Uptake in the Rat Substantia Nigra in Relation to the Release of Taurine from the Striatonigral Pathway (1990)
    Oxford, UK : Blackwell Publishing Ltd
    European journal of neuroscience 2 (1990), S. 0 
    Details
    ISSN: 1460-9568
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: The autoradiographic localization of radiolabelled taurine taken up in the rat substantia nigra in vivo together with conditions of release of the [3H]taurine taken up into brain slices were studied to determine whether they are consistent with the hypothesis that taurine may act as a neurotransmitter in the striatonigral pathway.At the light microscopic level the main cellular elements that became radiolabelled following the injection of [3H]taurine into the substantia nigra could be identified as glial cells. Electron microscope autoradiography confirmed that a subpopulation of glial cells including astrocytes, pericytes, and oligodendrocytes were radiolabelled and that neuronal perikarya were not radiolabelled. In addition, axonal elements including both terminal and preterminal boutons were found to have silver grains overlying them and were thus considered to be radiolabelled. This was supported by a quantitative analysis of the distribution of the silver grains; whereas glial elements had a significantly higher number of grains associated with them than with any other structure, axonal elements had a significantly greater number of grains than dendritic structures.Release of the preloaded [3H]taurine from superfused slices of substantia nigra occurred in response to veratridine, was calcium-dependent and was sensitive to inhibition by high magnesium concentrations or tetrodotoxin. Following the destruction of neurons in the striatum by ibotenic acid injections, although the weight of the ipsilateral substantia nigra was reduced, the uptake of [3H]taurine was not altered. In contrast to this, the veratridine-stimulated release was markedly attenuated, implying that the destruction of striatal neurons causes the loss of sites in the substantia nigra from which exogenous taurine is released.These results add further support to previous suggestions that taurine might act as a neurotransmitter or neuromodulator in the striatonigral pathway.
