    Notes: Abstract In a two-lever, food-reinforced drug-discrimination paradigm separate groups of rats were trained to discriminate either arecoline, pilocarpine or oxotremorine from saline. The discriminative cues of all three agonists were potently blocked by scopolamine, but only by 30–60 fold higher doses of methylscopolamine. The three agonists all suppressed overall response rate. These rate-suppressant effects were not blocked by scopolamine in doses which blocked the discriminative cues. In generalization tests, arecoline elicited selection of the drug-appropriate lever in all groups of trained animals. Pilocarpine was discriminated as drug by all pilocarpine-trained animals and by a majority of oxotremorine-trained animals, but was not significantly discriminated by the arecoline-trained group. Oxotremorine was discriminated by all oxotremorine-trained animals but only by some pilocarpine-trained animals, and was not significantly discriminated by the arecoline-trained group. Morphine, haloperidol, chlordiazepoxide, pentobarbital and nicotine were not generalized to any of the training drugs. The discriminative stimuli produced by the training drugs are therefore specific and exhibit properties indicative of an origin at central muscarinic receptors but may not be identical.

    Description / Table of Contents: Zusammenfassung Bei 185 Patienten (8/74 bis 12/86) im Alter von 19–85 J. (Median 66 J.) wurde wegen Residualsteins bei noch liegendem T-Drain die EST vorgenommen. EST und Steinextraktion gelangen bei je 93%. Alle Komplikationen (9,3%) waren leicht und konservativ beherrschbar. Die Letalität nach EST war 0, nach offener 2. Revision 1,8%. 34% waren zur Zeit der EST unter 50 J. alt. Kontrollen 2,5 bis 9 J. nach EST ergaben Beschwerdefreiheit bei 95%, AP-Erhöhungen bei 7%, sonographisch Aerobilie bei 20%. Das Risiko der Spät-Cholangitis nach EST ist nach wie vor unbekannt. Beobachtungen über 3–4 Jahrzehnte und leberhistologische Befunde sind erforderlich.
    Notes: Summary In 185 patients (August 1974 to December 1986), aged 19–85 years (median 66 years), with indwelling T-tube drains, endoscopic sphincterotomy was performed for residual biliary concrements. EST and stone extraction both had a success rate of 93%. All complications (9.3%) responded to conservative therapy. Lethality was 0% for EST and 1.8% for open biliary revision. At the time of EST, 34% were under 50 years of age. Follow-up at an interval of 2.5–9 years after EST indicated no pain in 95%, elevated AP in 7%, and sonographic aerobilia in 20%. The risk of late cholangitis is still unknown. Follow-ups over a period of 4–5 decades and histological examination of liver biopsies are essential.

    Description / Table of Contents: Zusammenfassung Durch ein aggressiveres endoskopisch-chirurgisches Therapieschema (endoskopische Blutstillung unabhängig vom Forrest-Stadium, F Ia: Auch nach erfolgreicher Unterspritzung OP innerhalb 6 h, F Ib, II: Kontroll-Endoskopie und evtl. nochmalige Unterspritzung) konnten die Ergebnisse -signifikant verbessert werden: Senkung der Re-Blutungsrate von 35% auf 16% (P〈0,05), der Notfall-OP-Rate wegen Re-Blutung von 66% auf 28% (P 〈 0,05), Senkung der Letalität von 14,3% auf 6,3%.
    Notes: Summary Using a new therapeutic regimen for bleeding peptic ulcers, the results improved significantly: endoscopic hemostasis regardless of the Forrest stage, F I a: early operation within 6 h, even if the primary endoscopic hemostasis was successful; F I b, 11: second endoscopy within 24 h and repeat hemostasis, if necessary. The rate of rebleeding was reduced from 35% to 16% (sP〈 0.05), the rate of emergency operations due to rebleeding from 66% to 28% (P〈0.05), and mortality decreased from 14.3% to 6.3%.

    A peak in the η ω mass spectrum from diffractive photoproduction (1987)

    Notes: Abstract The η ω mass spectrum resulting from diffractive photoproduction, by photons of 25–50 GeV, shows a peak at a mass of 1.61±0.04 GeV and width of 0.23±0.08 GeV. Comparison with the corresponding η ρ0 mass spectrum suggests that a resonance interpretation is favoured.

    Diffractive photoproduction of ab 1π system (1987)
    Springer

    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract It is shown that a likely interpretation of theb 1 ± π∓ mass spectrum from diffractive photoproduction is that it is due to contributions from the ω3(1670), in accord with corresponding production of the ρ3(1690), and from a further peak with a mass of 1.88±0.04 GeV and a width ≦0.3 GeV. The possibility that this latter peak can be due to a group of $$q\bar qg$$ hybrid states, as proposed by Isgur and Paton, is explored.

    Description / Table of Contents: Crystal Structures of Loellingite FeAs2 and of Pyrite RuTe2The structures of loellingite FeAs2 and pyrite type RuTe2 hitherto only known from powder measurements were redetermined by single crystal X-ray methods. Single crystals of FeAs2 (as large as 6 × 2 × 2 mm) were grown by CVD method with iodine in a temperature gradient of 800°C to 765°C, those of RuTe2 from a Te flux. The refinements of the structural parameters yielded a final R = 3.9% for 511 observed reflections (1 〉 2σI) of FeAs2 and R = 3.8% (3.7%) for 429 (410) reflections (I 〉 3σI) of RuTe2 (two experiments). For RuTe2, there are some intensities (even with I 〉 2σI) due to simultaneous diffraction.
    Notes: Die bisher nur aus Pulverdaten bekannten Strukturen der Verbindungen FeAs2 (Löllingit) und RuTe2 (Pyrit) wurden anhand von Einkristalldaten neu bestimmt. Die Darstellung der FeAs2-Einkristalle (Kantenlänge bis zu 6 mm) erfolgte durch Gasphasentransport mit Iod, die Einkristalle des RuTe2 wurden aus einer Tellurschmelze erhalten. Die Verfeinerung der Strukturparameter konvergierte beim FeAs2 für 511 beobachtete Reflexe (I 〉 2σI) bei R = 3.9% und beim RuTe2 für 429(410) beobachtete Reflexe (I 〉 3σI) bei 3,8% (3,7%) (zwei Kristalle). Einige Reflexe des RuTe2 mit I 〉 2σI sind auf Mehrfachreflexionen zurückzführen.
