    Notes: A 5.4 m-long 239-pole undulator comprising three rigid and precise standardized-unit undulators was completed and installed in the Tristan main ring, which was operated as a light source at a beam energy from 8 to 10 GeV. This undulator was successfully tested, characterized and used as a brilliant hard X-ray source for several synchrotron radiation experiments during the last 3.5 months of 1995.

    Measurement of the structure factors of diamond (1990)

    Notes: The absolute values of the structure factors of diamond are determined for nine low-order reflections by measuring the X-ray Pendellösung beats on the wavelength scale. Parallel-sided wafers of synthetic diamond single crystals are used for specimens. The deformation charge density and the Debye-Waller B factor are evaluated from the structure factors. The charge density of pile-up electrons is estimated to be 0.44(17) eÅ-3 at the midpoint between the nearest-neighbour atoms. The density is slightly smaller than that determined by the powder diffraction method. The obtained B factor, 0.142 (9) Å2, is in good agreement with that evaluated to date from neutron diffraction measurements.

    The Japanese food distribution system and the Large Scale Retail Store Law (1997)
    Bingley : Emerald
    International journal of social economics 24 (1997), S. 197-206 
    Details
    ISSN: 0306-8293
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: Spotlights important developments in the Japanese food distribution system over the past two to three years. States that, foreign pressure, combined with economic and social change in Japan, has forced the Japanese Government to alter some government regulations, including the Large Scale Retail Store Law. Reports that these regulatory changes, combined with other changes in the Japanese economy and society, have led to an increase in the number of supermarkets in Japan, and also to an expansion in the number of convenience stores and mini supermarkets. Discusses these developments and outlines possible implications for foreign firms interested in selling into the Japanese food market.

    Selective loss of nigral neurons in Pick's disease: a morphometric study (1990)
    Springer
    Acta neuropathologica 81 (1990), S. 155-161 
    Details
    ISSN: 1432-0533
    Keywords: Pick's disease ; Substantia nigra ; Pigmented neurons ; Morphometry ; Parkinsonism

    Topics: Medicine
    Notes: Summary Loss of neurons from the substantia nigra (SN), which is often encountered in Pick's disease, was quantitatively analyzed in 13 cases of Pick's disease and 19 age-matched controls. On sections from the upper and lower portions of the SN, the pigmeted zone (zona compacta) and the non-pigmented zone (zona reticulata) were delineated, and these zones were partitioned into quarters: medial, mid-medial, mid-lateral and lateral. Neuronal loss was fairly severe and more evident in the upper section of the SN (−40%), especially in the midmedial and lateral quarters. In the lower section (neuronal loss:−28%), the medial quarter was most severely affected. Non-pigmented neurons were preserved. Fibrillary gliosis was denser in the zona reticulata, where neuronal loss was minimal. These findings revealed a selective vulnerability of nigral neurons according to their topography and pigmentation and suggests the primary involvement of some neuronal groups (especially the pigmented neurons) of the SN in Pick's disease.

    Distribution of cerebral cortical lesions in corticobasal degeneration: a clinicopathological study of five autopsy cases in Japan (1997)

    Notes: Abstract We investigated five Japanese patients with autopsy-proven corticobasal degeneration (CBD) both clinically and pathologically, and examined the distribution of their cerebral cortical lesions in hemisphere specimens. The lesions were classified into three categories (slight, moderate and severe). Only two of our patients had clinical features considered to be typical of CBD. Severe lesions were present in the posterior portions of the frontal lobe, anterior to the precentral gyrus in two patients with the clinical diagnosis of CBD. By comparison, in two patients with clinically diagnosed frontal Pick’s disease, and one with the clinical diagnosis of progressive supranuclear palsy (PSP), severe lesions were seen in the anterior portions of the frontal lobe. The primary motor area of all five had mostly slight to moderate lesions. We postulate that the clinical features of CBD have a much wider spectrum than previously believed. Our data also indicate that the lesion responsible for limb-kinetic apraxia in CBD is in the premotor cortex. We suggest that when the anterior portions of the frontal lobe are damaged, the clinical picture mimics those of Pick’s disease and PSP. In addition, we consider that focal cerebral atrophy of CBD is multicentric.

    Vitamin E deficiency in acquired fat malabsorption (1990)
    Springer
    Journal of neurology 237 (1990), S. 103-106 
    Details
    ISSN: 1432-1459
    Keywords: Vitamin E deficiency ; Fat malabsorption ; Diabetes mellitus ; Chronic pancreatitis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Thirteen patients with adult-onset vitamin E deficiency due to fat malabsorption were investigated clinically and electrophysiologically. These patients had slightly or moderately decreased serum vitamin E (1.7–4.8 μg/ml, normal 〈6.0) or vitamin E/cholesterol ratio (0.21–0.31 mg/g, normal 〈0.35). Only one patient had typical neurological manifestations of vitamin E deficiency, which improved with supplementary vitamin E. The pathological findings in this patient were also compatible with vitamin E deficiency. This patient had poorly controlled diabetes mellitus due to advanced chronic pancreatitis. Reviewing previously reported cases of vitamin E deficiency with diabetes mellitus in chronic pancreatitis, the duration of deficiency until the onset of symptoms was shorter than in those cases without complications. Although adult patients with early, slight deficiency of vitamin E are generally asymptomatic, patients with diabetes mellitus tend to have early neurological symptoms. The vitamin E tolerance test should be used, because even in some patients with vitamin E deficiency due to malabsorption, the deficiency can be overcome by large oral doses of vitamin E.
