    Notes: Abstract Familial amyloid polyneuropathy (FAP) is an autosomal dominant disorder originally and most frequently described in Portugal. The usual constituent amyloid fibril protein is transthyretin (TTR) and the most frequent mutation in the TTR gene associated with FAP (including all Portuguese cases) is that at position 30 (met 30). Three different TTR haplotypes have been described in association with the met 30 mutation in European patients. We studied the haplotypes of 27 families (24 French, 2 British and 1 Greek) with FAP met 30 by analysing three polymorphisms in introns of the TTR gene. We also studied 6 families (2 British, 3 French and 1 Spanish) with FAP tyr 77. There were two main haplotypes in French patients with FAP met 30, one most commonly seen in the French families of Portuguese descent which was the same haplotype as previously described in Portuguese patients (haplotype I) and another haplotype (III) detected in most informative French families not of Portuguese origin. The age of onset of symptoms was consistently later in French than in Portuguese patients and in patients with haplotype III as the disease-associated haplotype rather than haplotype I. British and French patients with the tyr 77 mutation had different haplotypes. The most likely explanation of these findings is multiple founders of both mutations.

    Three-dimensional imaging of walleye pollock otoliths: reconstruction from serial sections and fluorescent laser cytometry (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 47 (1995), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Two techniques have been developed to examine the three-dimensional internal structure of otoliths. In the first, otoliths were sectioned serially, images were digitized, and the otolith was reconstructed as a computer model. In the second method growth increments were marked in vivo during their formation by immersing the fish in a fluorescent dye, and then the internal structure of the otolith visualized using laser cytometry. The results are useful for evaluating the potential for bias in otolith measurements and for determining the sectional plane with the least bias.

    The magnetic and microstructural properties of Pt/Co multilayers grown on ZnO : 37th Annual conference on magnetism and magnetic materials (1993)

    Notes: We measured the magnetic properties and examined the microstructure of Pt/Co multilayers sputtered at ambient temperature on ZnO underlayers grown between 25 and 500 °C. For ZnO grown at 150 °C, the perpendicular magnetic anisotropy energy of Pt/Co multilayers was a maximum, ∼1.1×107 erg/cm3, and then decreased monotonically to ∼3×106 erg/cm3 for ZnO grown at 500 °C. From measuring the angular dependence of magnetic coercivity, we deduced that magnetic reversal was by domain-wall motion in multilayers on low temperature (≤200 °C) ZnO, and predominantly by rotation on high-temperature ZnO. By cross-sectional transmission electron microscopy of Pt and Co layers on ZnO, we determined that all layers were rougher for high ZnO growth temperatures, although higher temperature promoted better multilayer (111)-fcc texture. The microstructure of Pt/Co multilayers on high-temperature ZnO was also particulate or granular, compared to more continuous on low-temperature ZnO. We concluded that the multilayer roughness reduced perpendicular magnetic anisotropy, and that particulate structural features caused magnetic reversal by rotation.

    An evaluation of ultrasound imaging for identificationof lumbar intervertebral level (2002)
    Oxford, UK : Blackwell Science Ltd

    Topics: Medicine
    Notes: The accuracy of ultrasound imaging to identify lumbar intervertebral level was assessed in 50 patients undergoing X-ray of the lumbar spine. Using an ultraviolet marker, an anaesthetist attempted to mark the L2/3, L3/4 and L4/5 intervertebral spaces. A radiologist unaware of these marks attempted to mark the same spaces with the aid of ultrasound imaging. X-ray-visible pellets were taped to the back at the various marks prior to lateral lumbar X-ray. Ultrasound imaging identified the correct level in up to 71% of cases, but palpation was successful in only 30% (p 〈 0.001). Up to 27% of marks using the palpation method were more than one spinal level above or below the assumed level using palpation, but none were more than one level high or low using ultrasound guidance.

    Installation and initial operation of the Suss Advanced Lithography Model 4 X-ray Stepper : The 9th National conference on synchrotron radiation instrumentation (1996)

    Notes: A Suss Advanced Lithography X-ray Stepper designed as a production tool for high throughput in the sub-quarter-micron device range has been installed and is being commissioned at the University of Wisconsin's Center for X-ray Lithography (CXrL). Illumination for the stepper is provided by a scanning beamline designed and constructed at CXrL. The beamline optical components are a gold-coated plane mirror, a 1-micron-thick silicon carbide window, and a 25-micron-thick beryllium exit window. Beamline features include synchronized scanning of the mirror and exit window, variable scan velocity to compensate for reflectivity changes as a function of incident angle, and a horizontal oscillation of the beryllium window during vertical scanning to average the effects of nonuniform beryllium window transmission. A helium purged snout transports the x-rays from the beamline exit window, to the exposure plane in the stepper. This snout is retractable to allow for the loading and unloading of masks into the stepper. The motions of the mirror, exit window, and snout are computer controlled by a LABVIEW program that communicates with the stepper control software. The design of the beamline and initial operating experiences with the beamline and stepper will be discussed. © 1996 American Institute of Physics.

    Measurement of the silver freezing point with an optical fiber thermometer: Proof of concept (1986)

    Notes: Measurements were made at the gold and silver freezing points to demonstrate the accuracy of the new optical fiber thermometer (OFT). It is shown that the output signal from the OFT is related to the radiance from a blackbody source in a simple manner and that the temperature interval between the gold and silver freezing points, as determined with the OFT, is close to other recent results.

    X-ray damage in low temperature ultrathin silicon dioxide (1992)

    Notes: The electrical characteristics of ultrathin oxides used in an x-ray lithography n-channel metal-oxide-silicon process grown at 700 and 950 °C were studied. The breakdown field exceeded 15 MV/cm for both low and high temperature oxides and the interface trap density of the fresh oxide was of order of 1010 cm−2 eV−1. Oxides grown at 950 °C had a lower interface trap density than 700 °C oxides, but 950 °C oxides are more sensitive to x-ray radiation damage. After 350 °C hydrogen annealing about 80% of the radiation damage in the form of interface traps was recovered.
