    Notizen: A tensile-strained five-step asymmetric coupled quantum well (FACQW) structure is proposed for large field-induced refractive index change without polarization dependence and redshift of the absorption edge. A strong exciton absorption peak is caused by electron-hole transitions between symmetric wave functions and antisymmetric wave functions with a small applied electric field. The field-induced refractive index change of strained the FACQW is larger by one order of magnitude compared to that of a rectangular quantum well and the difference in the refractive index change of TE and TM modes is under 2% when the operation wavelength is not at the absorption edge. © 1997 American Institute of Physics.

    Notizen: Abstract. Two patients with a large leiomyoma arising from the gastric fundus underwent laparoscopic resection. In case 1, the tumor was located in the anterior wall of the gastric fundus. To prevent stenosis and preserve the volume of the residual stomach, intragastric resection was adopted. The tumor was markedly and resected with laparosonic coagulating shears with a 1-cm safety margin. In case 2, a large tumor was detected in the duodenal bulb. Serious hemorrhage mandated emergency resection. The tumor originated from the posterior wall of the fundus. Attempts at reduction with the forceps failed. Reduction by digital manipulation via laparoscopic port sites was successful. An endostapler was used to resect the tumor and close the anterior wall. Both patients recovered uneventfully.

    Notizen: Abstract. pp and πd scattering and pp →πd reaction processes at incident proton laboratory energies T L ≤ 1 GeV are studied in the framework of πNN dynamics. For this purpose three-body calculations are performed with the πN interaction in the P 11, P 33, S 11 and S 31 states and NN forces in the 3 S 1 -3 D 1, 1 S 0, and 3 P 2 states. In addition, the backward-going pion contribution at the πNΔ vertex, the πN-ρN coupling, the heavy-meson exchanges in the NN → NN driving term, and the effect of the off-shell structure in the πN-ρN P 33 interaction are taken into account.

    Notizen: Abstract Wilson disease (WD) is an autosomal recessive disorder of copper accumulation leading to liver and/or brain damage. In this paper, we describe the results of a pilot study of screening for WD using ceruloplasmin determinations in dried blood samples. Specimens were collected from children aged 1 to 6 years who were seen at local paediatric outpatient clinics in the Miyagi Prefecture. We measured ceruloplasmin (CP) concentrations in 2789 children using an enzyme-linked immunosorbent assay. The mean value was 12.4±3.95 mg/dl blood. Among these children, we identified two (case 1, male, 2 years old; case 2, female, 3 years old) with markedly reduced CP concentrations. Apart from low serum copper concentrations, their biochemical findings were almost normal, as were growth and development. To confirm the diagnosis, we analysed the WD gene and detected A803T/2871delC mutations in case 1 and R778L/G1035V mutations in case 2. We conclude that these children were presymptomatic WD patients. The CP level in dried blood samples from children aged 1 to 6 years appears to be a reliable marker for early detection of WD.
