    Surface wave and lithospheric structure across the northwestern part of the Indian peninsula (1991)

    Notes: Abstract Group velocities of fundamental mode Rayleigh and Love waves have been obtained across the central highlands in the northwestern part of the Indian peninsula and across the plateau region of the peninsula. Such data across the latter region were also obtained earlier and revealed model lithosphere IP11 for this region. Data of the two regions are similar and show that the lithospheric model IP11 continues from the plateau region to the central highlands. The model IP11 has been verified by comparing observed Love wave forms with synthetics ones.

    Heterogeneity of dystrophin expression in patients with Duchenne and Becker muscular dystrophy (1990)
    Springer
    Acta neuropathologica 80 (1990), S. 239-250

    ISSN: 1432-0533
    Keywords: Dystrophin ; Duchenne muscular dystrophy ; Becker muscular dystrophy ; Muscle proteins

    Topics: Medicine
    Notes: Summary This report documents the results of an integrated biochemical and immunocytochemical investigation into the expression of dystrophin (the protein product of the Duchenne muscular dystrophy gene) in muscle biopsies from 226 patients. It is the first study in which dystrophin has been analysed on blots and on tissue sections in such a large number of patients using the same (monoclonal) antibody. The 140 patients with Xp21 muscular dystrophy who were included in this study represent a continuous spectrum of disease severity and this range was reflected in the heterogeneity of dystrophin expression which was observed with respect to abundance, size and the pattern of tissue localisation. Approximately 40% of biopsies obtained from patients diagnosed as having Duchenne muscular, dystrophy (DMD) contained isolated clearly positive fibres and a further 20% had very weak labelling on a large number of fibres. Biopsies from patients with Becker muscular dystrophy (BMD) showed labelling patterns which varied from weak labelling on the majority of fibres to clear labelling on all fibres. Typically, however, there was inter-and intra-fibre variation in labelling intensity. Approximately 85% of the 52 BMD and 54 DMD patients who had unequivocal labelling on blots demonstrated a protein of abnormal size. The remaining 15% had a protein of normal size but reduced abundance. Overall, the estimated abundance of dystrophin correlated well with clinical assessments of the disease severity expressed in patients: We conclude that dystrophin analysis is an essential and dependable technique for the differential diagnosis of patients with Xp21 muscular dystrophy.

    Increased band sharing in DNA fingerprints of an inbred human population (1991)
    Springer
    Human genetics 〈Berlin〉 87 (1991), S. 341-347 
    Details

    Notes: Summary We have compared band sharing between the DNA fingerprints of members of an inbred human population with band sharing between members of an outbred population. It had not previously been determined whether the high rate of mutation at minisatellite loci is sufficient to prevent an increase in band sharing in moderately inbred populations. We have found that there is an increase in band sharing in the 2-kb to 9-kb size range, but not in the 〉9-kb size range, in the inbred population. The difference was consistently observed using four different multi-locus probes, viz. 33.6, 33.15, (CAC)5 and M13. Thus, we have demonstrated that moderate but prolonged inbreeding can lead to increased similarity in human DNA fingerprints. This should be considered when analysing DNA fingerprints in forensic or paternity cases involving members of an inbred community.

    Localisation of the gene for Norrie disease to between DXS7 and DXS426 on Xp (1992)

    Notes: Summary A highly informative microsatellite marker, DXS426, which maps proximal to DXS7 in the interval Xp11.4–Xp11.23, has been used to refine further the localisation of the gene for Norrie disease (NDP). The results from a multiply informative crossover localize the NDP gene proximal to DXS7. In conjunction with information from 2 NDP patients who have a deletion for DXS7 but not for DSX426, our data indicate that the NDP gene lies between DXS7 and DXS426 on proximal Xp.

    Mechanisms of optical response in superconducting YBa2Cu3O7−δ thin films and grain-boundary weak links (1994)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The optical response of single grain-boundary weak links in superconducting YBCO thin films has been investigated. At temperatures well below the transition temperature, the grain boundary exhibits an optical response which is qualitatively different from transition edge response. Using a resistively shunted-junction model for the grain-boundary weak link, we find that the optical response below the transition temperature can be described by radiation induced thermal modulation of the critical currents of the weak links. The dependence on the bias current and the temperature distinguishes the weak-link optical response from the transition edge optical response. We discuss novel aspects of a potential radiation detector based on grain-boundary weak-link junctions.

    Discontinuity of B-diffusion profiles at the interface of polycrystalline Si and single crystal Si (1993)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 73 (1993), S. 3800-3804

    ISSN: 1089-7550

    Notes: Boron diffusion in polycrystalline Si-on-single crystal Si systems has been studied by secondary ion mass spectrometry. The extrapolated B-diffusion profiles in polycrystalline Si and in the single crystal Si substrate reveal a discontinuity at the polycrystalline Si-single crystal Si interface. The discontinuity in the B profiles is believed to occur due to the blockage of B-defect complexes by the interfacial oxide between polycrystalline Si and the single-crystal Si substrate, as well as the immobility of these defect complexes in single crystal Si. The B in the implant peak region above the B solid solubility limit is found to be immobile in single crystal Si during annealing due to the formation of electrically inactive B-defect complexes. In polycrystalline Si, however, our results show that the B in the peak region spreads out more rapidly than in single crystal Si possibly due to the diffusion of B-defect complexes along grain boundaries. The B-defect complexes are electrically inactive as determined by spreading resistance analysis. If the B concentration is lowered below the solid solubility limit, either by decreasing the dose or by raising the anneal temperature, no discontinuity is observed in the B profile across the polycrystalline Si-single crystal Si interface.

    Torsade de pointes and long QT syndrome following major blood transfusion (1992)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: We report a rare complication following transfusion of a large volume of blood in an adult patient. An electrophysiological disturbance of the cardiac cycle with prolongation of the QT interval developed, which was followed by recurrent episodes of torsade de pointes, a unique form of ventricular tachycardia. The most likely cause of this acquired long QT syndrome was hypomagnesaemia secondary to massive blood transfusion. Treatment with a magnesium infusion restored the QT interval to normal and temporary ventricular pacing prevented further ventricular arrhythmias.
