    Treatment with allyl alcohol selects specifically for mutants of Clostridium acetobutylicum defective in butanol synthesis (1986)

    Notizen: Abstract Treatment of Clostridium acetobutylicum with allyl alcohol allowed the selection of mutants which were unable to produce n-butanol, whereas the synthesis of acetone and ethanol was unaffected. Enzymatic investigations revealed that all mutant strains were devoid of butyraldehyde dehydrogenase or showed a very low activity of this enzyme as compared to the wild type.

    Zur Technik der Vitamin C-Bestimmung Mittels Dichlorphenol-Indophenol (1941)
    Springer
    Journal of molecular medicine 20 (1941), S. 1174-1176

    Thema: Medizin
    Notizen: Zusammenfassung Es wird eine neue Methode zur Bestimmung von Ascorbinsäure mittels Dichlorphenol-Indophenol beschrieben, die darin besteht, der zu titrierenden Lösung einen geringen Überschuß an Farbstoff zuzusetzen (2 ccm über den annähernden Umschlagpunkt) und diesen Überschuß nach 1/2 Minute mit einer n/200 -Lösung von Mohrschem Salz in Gegenwart von Natriumoxalat zurückzutitrieren. Die Methode liefert einen scharfen Umschlagpunkt im Gegensatz zu der ziehenden direkten Titration. Es werden Vergleichsanalysen für direkte Titration und Rücktitration gegeben, die gute Übereinstimmung ergeben.

    Notizen: Summary The action of the non-steroidal antiinflammatory drugs indomethacin, tiaprofenic acid, diclofenac and meclofenamate on vascular and plateletcyclooxygenases was studied by measuring the arachidonic acid-induced thromboxane A2 (TXA2)-formation of washed human platelets and prostacyclin (PGI2)-formation of bovine coronary artery rings. TXA2 was bioassayed as RCS on rabbit aorta strips, PGI2 in terms of its antiaggregatory activity on ADP-induced aggregation of human platelet-rich plasma. All of the substances studied produced concentration-dependent inhibition of PGI2- and RCS-release. The IC50 [μM] in inhibition of RCS-formation was 0.019 for indomethacin, 0.070 for tiaprofenic acid but 44.9 for meclofenamate and 63.2 for diclofenac. The IC50 [μM] in inhibition of PGI2-release was 0.42 for diclofenac, 0.63 for indomethacin and 0.99 for tiaprofenic acid. The data suggest (1) high sensitivity of human platelet-cyclooxygenase against indomethacin and tiaprofenic acid, (2) different sequence of the substances studied in inhibiting arachidonic acid-induced TXA2- and PGI2-formation. The possible therapeutic value of selective inhibition of platelets and vascular cyclooxygenases in discussed.

    Althesin interaction with human plasma steroid binding globulins (1985)
    Springer
    European journal of clinical pharmacology 29 (1985), S. 181-185

    Notizen: Summary The binding affinities of two steroid anaesthetics, alphaxalone (Alfx) and alphadolone acetate (Alfd), for testosterone-oestradiol-binding globulin (TeBG) and corticosteroid-binding globulin (CBG) were measured in human serum. In 8 male patients, the effect of i.v. administration of Althesin (a mixture of Alfx and Alfd) on the transport of testosterone (T) and cortisol (F) was studied. Both Alfx and Alfd bind to TeBG and CBG with a relatively high affinity (106M−1). A significant change in the percentage of unbound T was observed during Althesin infusion, with no change in total T concentration or in the TeBG binding parameters. The results suggest that by interaction with TeBG binding sites Alfx and/or Alfd displaced T bound to TeBG, and transiently increased the percentage of unbound T. A significant increase in the concentration of F was observed during althesin infusion, while the percentage of unbound F and the CBG binding parameters were unchanged. The dose of Alfx and Alfd used was not sufficient to alter the transport of F during brief althesin anaesthesia in men.

    pH changes at near-electrode surfaces (1983)
    Springer
    Journal of applied electrochemistry 13 (1983), S. 189-207 
    Details
    ISSN: 1572-8838
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie , Elektrotechnik, Elektronik, Nachrichtentechnik
    Notizen: Abstract Anodic or cathodic processes in which protons are released or consumed, respectively, lead to local pH changes at the electrode surface. The phenomenon is important in several branches of metal finishing, in corrosion, electro-organic synthesis and other branches of applied electrochemistry, as well as being a factor which can invalidate mechanistic investigations. The concept of ‘pHs’ (near-surface pH) is examined, as are the experimental techniques which have been used to measure it. Many of these are inherently weak. Published results are shown to be largely discrepant, both in respect of the magnitude of the effect and even its incidence. Attempts to treat the phenomenon theoretically are briefly summarized.

    Electrical leakage currents in bipolar cell stacks (1980)
    Springer
    Journal of applied electrochemistry 10 (1980), S. 233-237

    Notizen: Abstract A brief review of the origins of bipolar leakage currents, the means used for its measurement and calculation and the importance of minimizing the phenomenon, is followed by a novel means of computing leakage currents more accurately than hitherto possible, using a commercially available simulation program. This has the further advantage that the reali-V characteristics of an electrochemical cell can be used, there being no need to represent the cell itself as a zener diode which is a poor representation of reali-V cell characteristics.
