    Notes: Room temperature continuous wave operation of ZnSe-based blue/green laser diodes grown homoepitaxially on conductive ZnSe substrates with threshold current densities as low as 176 A/cm2 has been demonstrated. This is the lowest reported threshold among all short wavelength lasers in the blue/green region. Lifetimes at room temperature of up to 2.1 h have been obtained for lasers with pre-existing defect densities lower than 3×104 cm−2. © 1998 American Institute of Physics.

    Notes: The saturation of the critical current as a function of the gate voltage found in the Nb-Si-Nb superconducting field effect transistor is analyzed numerically using the de Gennes expression for the proximity effect. According to the analysis, (i) the Schottky barrier effect is found to be negligible under experimental conditions, (ii) mobility of silicon fitted to the experimental curve shows a power relation to the gate voltage with exponent of about −0.81. This exponent is consistent with the results from independent experiments and a simple theory of surface scattering. The results indicate that the surface scattering effect causes the saturation phenomenon.

    Notes: A recovery process of minority-carrier recombination lifetime after ultraviolet (UV) irradiation has been investigated with a laser-microwave photoconductance technique for silicon wafers with native oxide. It is found that the effective lifetime which greatly increases after UV irradiation recovers to the initial value primarily with an exponential law characterized by a specific time constant called recovery time. The recovery time depends on experimental conditions where, for example, an accumulation effect of UV irradiation is observed. A mechanism of the effective lifetime recovery process is correlated mainly with the behavior of slow states associated with the silicon/native oxide interface.

    Notes: Minority carrier conductance mobility was measured in a noncontact fashion using a laser excitation/microwave reflection photoconductance technique. The mobility was obtained from the surface component of recombination lifetime via measurements of effective lifetime on sample pairs which consist of an oxidized wafer, which is subsequently damaged by lapping, or two lapped wafers with different thicknesses. The experimental temperature dependence of mobility was compared with theoretical predictions given by semiempirical formulas. A good agreement between experimental data and theoretical calculations for both measurement algorithms and n- and p-type conductivity silicon material was obtained.

    Description / Table of Contents: Résumé La perfusion continue hyperthermique (CHPP) avec une solution contenant 30 mg de mytomycine C (MMC) et 300 mg de cisplatine (CDDP) a été utilisée comme traitement prophylactique pour prévenir la récidive péritonéale chez 79 patients avec un cancer gastrique avancé réséqué. Un groupe composé de 81 patients avec un cancer gastrique avancé qui ont eu une chirurgie à visée curatrice pendant la même période de temps a servi de contrôle. La CHPP, perfusion de MMC et de CDDP mélangés au sérum physiologique réchauffé à 43.5°C par un appareil spécial, était administrée pendant 60 minutes. Lorsque l'envahissement séreux a été confirmé par l'examen anatomopathologique, la survie des patients ayant eu la CHHP était significativement plus longue que lorsque les patients n'avaient pas eu de CHHP. La survie des patients classés stade IV était également améliorée. Il n'y avait aucune amélioration, par contre, de la survie lorsque la couche séreuse n'était pas envahie. Des effets secondaires ont été observés chez quatre patients qui ont une CHHP: un a développé une aplasie médullaire sévère, alors que les trois autres n'ont eu qu'une hyperazotémie transitoire. Il n'y avait, en définitive, aucune différence de mortalité ou de morbidité entre les deux groupes. Ces résultats indiquent que la CHPP est sûre et facilement disponible comme thérapie prophylactique contre la récidive péritonéale après résection de cancer gastrique.
    Abstract: Resumen La perfusión hipertérmica peritoneal continua (CHPP) con una solución que contiene 30 mg de mitomicina C y 300 mg de cisplatino ha sido introducida como tratamiento profiláctico para prevenir recurrencia peritoneal luego de la resección curativa en 79 pacientes con cáncer gástrico avanzado. El grupo control consistió en 81 pacientes con cáncer gástrico avanzado que fueron sometidos a cirugía curativa en el mismo período de tiempo. La CHPP fue realizada durante 60 minutos con solución salina con MMC y CDDP calentada a 43.5°C por medio de un sistema de CHPP. En los pacientes con invasión serosa confirmada histológicamente, la tasa de sobrevida del grupo CHPP fue significativamente mayor que la del grupo control. También se detectó una ventaja de sobrevida en los pacientes en estado IV tratados con CHPP. Sin embargo, no se encontró ventaja en cuanto a sobrevida entre el grupo CHPP y el grupo control en los pacientes con tumores negativos para invasión serosa. Efectos adversos fueron registrados en 4 pacientes con CHPP:1 desarrolló severa depresión de la médula ósea, e hiperazotemia transitoria fue observada en los otros 3 pacientes. Sin embargo, no se halló diferencia en cuanto a mortalidad y morbilidad entre los dos grupos. Estos resultados indican que la CHPP es una modalidad terapéutica segura y fácilmente disponible para prevenir la recurrencia peritoneal luego de cirugía por cáncer.
    Notes: Abstract Continuous hyperthermic peritoneal perfusion (CHPP) with a solution which contains 30 mg mitomycin C and 300 mg cisplatin has been introduced as a prophylactic treatment for peritoneal recurrence after curative resection of 79 advanced gastric cancers. The control group consisted of 81 patients with advanced gastric cancer who underwent curative surgery during the same period. CHPP was performed for 60 minutes by perfusing MMC- and CDDP-containing saline solutions warmed at 43.5°C by a special CHPP device. In patients with pathologically confirmed serosal invasion-positive tumors, the survival rate of the CHPP group was significantly higher than that of the control group. A survival advantage for stage IV patients was also obtained by CHPP. However, there was no survival advantage between the CHPP group and the control group with serosal invasion-negative tumors. Adverse effects were observed in four patients who underwent CHPP: One developed severe bone marrow suppression, and transient hyperazotemia was ebserved in the other three. There was no difference in the incidence of mortality and morbidity between the two groups. These results indicate that CHPP is a safe, readily available prophylactic therapy for peritoneal recurrence after gastric cancer surgery.

    Notes: Abstract. An 11-month-old girl with congenital heart disease developed infective endocarditis. Blood cultures revealed an unusual gram-negative rod, Rahnella aquatilis. The patient was successfully treated with a combination of netilmicin and ceftazidime. This is the first case report of infective endocarditis caused by this organism. R. aquatilis should be recognized as a clinical pathogen capable of causing life-threatening infection in children and adults.

    Notes: Abstract E3330 {(2E)-3-[5-(2,3-dimethoxy-6-methyl-1,4-benzoquinoyl)]-2-nonly-2-propenoic acid}, a novel synthesized hepatoprotective compound, has suppressive effects on tumor necrosis factor-α (TNF-α) generation from monocytes/macrophagesin vitro. E3330 (1–100 μM) reduced lipopolysaccharide (LPS, 10 mg/ml or 1μg/ml)-induced TNF-α generation from rat resident andPropionibacterium acnes (P. acnes)-elicited peritoneal macrophages, rat and human monocytes, rat Kupffer cells, and splenic mononuclear cells in a concentration-dependent manner. E3330 also (1–100 μM) suppressed TNF-α generation stimulated with egg-albumin immune complex in ratP. acnes-elicited peritoneal macrophages. Northern blot analysis showed that LPS-induced expression of TNF-α messenger RNA (mRNA) in human blood monocytes was suppressed by E3330. These findings indicate that E3330 has a suppressive effect on TNF-α generation from monocytes/macrophages, regardless of origin or species, and this effect is based in part on the suppression of TNF-α mRNA expression.

    Notes: Abstract To elucidate the role of collagenase in tissue destruction in chronic inflammation (e.g., in rheumatoid arthritis), we established a novel air pouch model in rats. Ten ml of air was injected subcutaneously on the dorsa of F344 rats, and 24 hours thereafter, Freund's complete adjuvant was injected into the air pouch. A remarkably high activity of trypsin-activated collagenase was detected dose-dependently in the pouch fluid at 8 days after the challenge injection. Concomitantly with the increase of collagenase activity, the weight of granuloma formed in the pouch decreased, suggesting that collagenase participates in the resorption of granuloma tissues.
