    Notes: Abstract: In contrast to brain, the scialic nerve concentration of vitamin E in rats increased rapidly during the postnatal period (approximately fivefold between days 1 and 8), then decreased dramatically (about twofold between days 8 and 30), and further decreased slowly between days 30 and 60 and remained constant up to 2 years. Although the sciatic nerve concentration of vitamin E decreased by 58% between days 8 and 30, the concentration of vitamin E in serum presented a marked decrease (∼75%). The vitamin E concentrations varied in a similar pattern in whole sciatic nerve and in endoneurium and showed a very close correlation (r= 0.94). The age-related changes in fatty acid concentration of the endoneurial fraction of the sciatic nerve were characterized by a large increase in content of saturated and monounsaturated fatty acids up to 6 months (twofold for saturated and fourfold for monounsaturated fatty acids). Then, up to 24 months, the amount of these fatty acids decreased very slowly. The content of (n-6) polyunsaturated fatty acids (PUFAs) decreased rapidly up to 1 year and slowly afterward. In contrast, during development the amount of (n-3) PUFA was relatively stable and decreased during aging. A highly significant correlation between vitamin E and (n-6) PUFA [18:2(n-6), 20:4(n-6), and total (n-6)) was observed but not between (n-3) PUFA and vitamin E. It is suggested that there may be a relationship between vitamin E and (n-6) PUFA in the PNS membranes during development and aging.

    Precursors for Cholesterol Synthesis (7-Dehydrocholesterol, 7-Dehydrodesmosterol, and Desmosterol): Cholesterol/7-Dehydrocholesterol Ratio as an Index of Development and Aging in PNS but Not in CNS (1990)

    Notes: In rat sciatic nerve, the 7-dehydrocholesterol content decreased dramatically during the postnatal period and slowly during adulthood and aging. In contrast, the 7-dehydrodesmosterol content peaked at 14 days and was nearly undetectable after 60 days. The desmosterol content peaked at 21 days and was nearly undetectable after 1 year. The cholesterol content increased up to 21 days and remained nearly constant thereafter. In brain (in contrast to sciatic nerve), 7-dehydrodesmosterol and desmosterol contents decreased dramatically during development and slightly during adulthood and aging; the 7-dehydrocholesterol content peaked at 21 days and remained constant during aging. Only 7-dehydrocholesterol was dramatically more concentrated in PNS than in CNS. In brain, the cholesterol/7-dehydrocholesterol ratio increased during development and remained stable after 6 months. In contrast, in sciatic nerve, this ratio continuously increased during development and aging (950-fold between 5 days and 18 months). Thus, the cholesterol/7-dehydrocholesterol ratio is a useful biochemical index of development and aging in the PNS.

    A typical case of pemphigoid gestationis with a unique pattern of intercellular immunofluorescence (1997)

    Notes: Pemphigoid gestationis is an autoimmune bullous disorder affecting pregnant women which typically presents in the second and third trimester of pregnancy with an itchy bullous eruption on the abdomen and limbs. The diagnosis is confirmed by the presence of complement-binding IgG antibasement membrane zone (BMZ) antibodies, which bind to the roof of salt-split skin. We describe a case of clinically typical pemphigoid gestationis with the combination of intercellular IgG and BMZ IgG and C3 staining on immunofluorescence, a pattern which is unique for this condition.

    Analysis of positron beam data by the combined use of the shape- and wing-parameters (1996)

    Notes: An improved approach is presented for the analysis of positron beam Doppler broadening data. Instead of analyzing the energy-dependent shape parameter, the so-called S(E) data, we combined the shape S(E) and wing W(E) data by plotting them as a trajectory in the S–W plane, using the implantation energy as a running parameter. It is shown that this plot is of particular interest for the qualitative interpretation of the data. Furthermore, it allows the independent determination of the characteristic shape and wing parameters of the different positron trapping layers without the use of a numerical simulation and fitting program. The method and its advantages and limitations are illustrated for three cases: a silicon sample implanted with helium, a metal–oxide–silicon system subjected to a bias voltage and a bare oxide layer on silicon. © 1996 American Institute of Physics.

    Notes: As-deposited iridium-silicon interface structures have been characterized by cross-section high-resolution transmission electron microscopy. Iridium films were deposited by an e-beam gun on (100) Si wafers heated at 200 °C during the deposition. A planar polycrystalline interfacial layer, 2–3 nm thick, was formed between the iridium and the silicon substrate. Thermodynamic calculations are presented which describe the development of the interfacial layer. Correlation between the observed structure and that proposed by thermodynamic calculations is discussed. © 1995 American Institute of Physics.

    Transport of positrons in the electrically biased metal-oxide-silicon system (1997)
    [S.l.] : American Institute of Physics (AIP)

    Notes: This paper describes a study of the effect of an external electric field on the behavior of positrons in metal-oxide-silicon (MOS) systems. Doppler broadening measurements of the annihilation radiation were performed on capacitors with identical thermally grown SiO2 layers and with Al, W and Au layers as a gate. The data were analyzed by the combined use of the shape- and wing-parameters of the photo peak. The observed effects of the electric field are due to the field-driven transport of positrons through the SiO2, silicon and the interfaces. By applying a field of the order of 1 MV/cm the positrons can be efficiently transported through the approximately 100 nm thick SiO2 layer. From the transport behavior of the positrons it is concluded that the positron affinity is higher for SiO2 than for silicon and for the gate metal. By properly choosing the direction of the field, the positrons implanted into the SiO2 layer are collected either at the Si/SiO2 interface or at the SiO2/gate interface. For negative gate bias the positrons implanted into the substrate, that diffuse back to the SiO2, are transported through the oxide layer and injected into the gate metal. This is the first time that field-assisted transport of positrons across an insulating layer has been demonstrated. © 1997 American Institute of Physics.

    The Clash of Globalizations in the Middle East (2007)

    Notes: Globalization connotes the removal of barriers between states to the movement of capital, goods and labor. While the lowering of barriers to the movement of factors of production has resulted in transnational networks of production and elements of an international civil society, it has also facilitated international terrorist networks, drug cartels and the like. In the Middle East, for strategic reasons discussed in this paper, the spectrum of barriers to be removed includes not just protectionist trade or monetary policies but the regimes as well. 'Regime change' can be brutal or gradual, imposed or developed from within. This paper examines the sorts of political change envisaged by the authors of the Arab Human Development Report 2002 to overcome the region's 'freedom deficit' as well as the darker, by now all too familiar, scenarios associating this dimension of globalization-- regime change--with American (multilateral or unilateral) military operations. The Middle East is home to most of the oil that fueled the world's first truly global industry, but the region may also become the epicenter of forces that reverse the globalizing tendencies of states.

    Notes: The most common forms of localized primary cutaneous amyloidosis are lichen (papular) and macular amyloidosis. Nodular or tumefactive amyloidosis is rare and demonstrates important clinical, historical, pathogenic and prognostic differences from the lichen and macular variants. We report two cases of nodular localized primary cutaneous amyloidosis.
