    Notizen: The fabrication of n+ and p+ silicon thin film by using a combination of "spin-on-glass'' and XeCl excimer-laser doping is described. The doping can be achieved by rapid dopant atom diffusion into molten silicon from a spin-coated film containing the dopant. This technology offers the advantages of process simplicity, low processing temperature, and ultrashallow high-concentration doping. The obtained sheet resistances (2 kΩ/(D'Alembertian) for n+ and 9 kΩ/(D'Alembertian) for p+) are acceptable for thin-film transistors (TFTs). The energy required for doping into a thin film was less than half of that for a silicon wafer. This is mainly due to the absorption rate difference between noncrystalline and crystalline silicon. This process appears extremely promising for TFT fabrication.

    Notizen: Abstract We present a patient with vertebrobasilar insufficiency, with vertigo and horizontal nystagmus, induced by turning the head to the right. Angiography demonstrated transient occlusion of the left vertebral artery at the atlantoaxial joint during rotation of the head. The pathogenesis and angiographic findings are discussed.

    Notizen: Summary The nucleotide sequences of the 5′-portion of the HCV genome, consisting of 2672 nucleotides, were determined by analysis of clones derived from 5 different patients with liver cirrhosis and hepatocellular carcinoma. Comparison of 5 genomes and 8 isolates already reported demonstrated the significant genome diversity in the structural regions. Genetic divergence was outstanding in the envelope regions (E1 and NS1/E2, 〉59.7% identity) in contrast to the sequence conservation of the 5′ non-coding (〉93.8% identity) or core regions (〉82.0% identity). Although hypervariable regions were found in the NS1/E2 region as reported, hydropathicity was maintained for all clones, reflecting the biological functions of these regions.

    Notizen: Abstract Two hundred and thirty eight persons were examined to evaluate the interrelations among seven key factors for arteriosclerosis: body mass index (BMI), systolic blood pressure (BPs), plasma glucose (PG), serum cholesterol (CHO), serum triglyceride (TG), serum glutamic-pyruvic transaminase (SGPT), and serum insulin (IRI). BPs showed the significant positive correlation with PG (r=0.346), BMI (r=0.318), and IRI (r=0.200).However, there were no significant correlations between BPs and CHO, between BPs and TG, between BPs and SGPT. SGPT showed the significant positive correlation with IRI (r=0.367), BMI (r=0.268), and TG (r=0.343); but no significant correlations were observed in relations between SGPT and PG, between SGPT and BPs, between SGPT and CHO. IRI showed the significant positive correlations with TG (r=0.234), and PG (r=0.427). These data suggest that IRI has an effect on BPs and SGPT. The effect of IRI on BPs relates with PG but does not relate with serum lipid. The effect of IRI on SGPT relates with TG but not with PG.

    Notizen: A new type of microelectrode array device has been developed using semiconductor-processing techniques. An array of 15 × 15 square electrodes as small as 1 μm, spaced 100 μm apart, has been fabricated on a silicon chip of dimensions 1.5 × 1.5 mm2. Steady state electrochemistry was performed using these devices in both aqueous and non-aqueous media.
