    Low-threshold operation of hemispherical microcavity single-quantum-well lasers at 4 K (1993)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 62 (1993), S. 443-445

    Notes: We demonstrate low-threshold lasing at 4 K in optically pumped hemispherical In0.2Ga0.8As single-quantum-well microcavities. The incident threshold pump power density is 11 kW/cm2 corresponding to an absorbed power density of about 320 W/cm2, and the measured spontaneous emission factor β is about 0.01.

    Notes: [Auszug] The quantum-mechanical properties of long-lived optical pulses known as solitons have recently been studied theoretically and observed experimentally. These experiments suggest effective ways of reducing quantum noise in signal transmission and of performing quantum-mechanical non-demolition ...

    In vitro effects of hyaluronan on prostaglandin E2 induction by interleukin-1 in rabbit articular chondrocytes (1993)
    Springer
    Inflammation research 38 (1993), S. 122-125

    ISSN: 1420-908X

    Topics: Medicine
    Notes: Abstract Effects of hyaluronan (HA) on the prostaglandin E2 (PGE2) production induced by recombinant human interleukin-1β (rhIL-1β) in rabbit articular chondrocytes were studiedin vitro. The rhIL-1β-induced PGE2 production was dose-dependently inhibited by HA. HA with the highest molecular weight (M r=2.0×106) exhibited an inhibitory effect that was statistically more significant than the same polymer of lower molecular weights (M r=1.0×106, 0.5×106). This effect was observed in both young and adult rabbit articular chondrocytes. Since PGE2 has been implicated as a mediator of inflammatory joint diseases, our observations suggest that HA may elicit an anti-inflammatory effect by inhibiting PGE2 production.

    Vertical lengthening of the unilateral cleft lip after a triangular flap repair (1993)

    Notes: Summary A triangular flap repair for unilateral cleft lip is stated to have the potential problem of creating a lip that is too long. Although preoperative measurements were performed with calipers, the gap created in the medial segment was directly measured during the procedure, in order to determine the size of the flap more precisely. Ninety patients with complete unilateral cleft lips underwent a triangular flap repair using this method. The symmetry of the Cupid's bow was evaluated at a follow-up period averaging between six years and three months. Sixty-two lips obtained “symmetry” and the remaining 28 cases showed a lip which was “too long”; none of the lips were “too short”. The comparison between 27 primary palate clefts (UCLA) and 63 primary and secondary palate clefts (UCLP) showed no significant difference in the surgical result. The preoperative shortness of the lip on the cleft side was significantly greater in the “too long” group (5.01 ± 0.95 mm) than in the “symmetry” group (4.40 ± 0.87 mm). The width of the flap used was significantly larger in the “too long” group (3.76 ± 0.79 mm) than in the “symmetry” group (3.42 ± 0.69 mm). The triangular flap repair with intraoperative measurements is considered to be beneficial, although preoperative measurements provide an optimal design in most cases. It is suggested that the use of a wider triangular flap results in a lip which tends to be too long in spite of the preoperative shortness on the cleft side.
