    Notes: [Auszug] Plasma was obtained from a 30 year old white female patient (B. C.) with abetalipoproteinaemia, through the generosity of Drs David Law and Walter Nance of Vander-bilt University. pLP was prepared from normal, fasting subjects by precipitation with heparin and manganese followed by ultracentrifugal ...

    Description / Table of Contents: Zusammenfassung Die Verfasser berichten vergleichend über vier Methoden zur Mineralisierung organischer Verbindungen, deren Schwefelgehalt bestimmt werden soll, und zwar die Verbrennung in der Knallgasflamme, im Sauerstoffstrom im leeren Rohr, im Schönigerkolben und die reduktive Zerstörung mit Kalium im verschlossenen Röhrchen. Diese Methoden wurden mit der maßanalytischen Bestimmung des Sulfats bzw. Sulfids kombiniert. Daraus ergab sich, daß die Reduktion mit Kalium und die nachfolgende jodometrische Bestimmung des Sulfids am allgemeinsten anwendbar und am sichersten ist.
    Abstract: Résumé Four methods of mineralization of organic compounds are recalled and compared with respect to determining sulfur in them; they are the oxyhydrogen combustion method, combustion in oxygen, in an empty tube, or in a flask of the Schöniger type, and the reductive mineralization in a sealed tube by potassium. They are combined with the titration methods for the SO4 2− or S2− ions. This study has enabled the authors to select the reductive method of mineralization by means of potassium followed by the iodometric titration of S2− ions as the most general and most reliable among the various procedures.
    Notes: Résumé Les auteurs rappellent et comparent quatre méthodes de minéralisation des composés organiques en vue d'y doser le soufre: ce sont la méthode de combustion oxhydrique, la combustion dans l'oxygène, soit en tube droit vide, soit en fiole du type «Schöniger» et la minéralisation réductrice en tube scellé par le potassium. Ils les associent aux méthodes de titrage des ions SO4 2− ou S2−. Leur étude leur permet de sélectionner parmi les méthodes décrites la minéralisation réductrice par le potassium associée au titrage iodométrique des ions S2− comme la plus universelle et la plus sûre d'entre elles.

    Notes: [Auszug] Beta-lipoprotein was prepared by ultracentrifugation alone or by precipitation with heparin and manganese followed by ultracentrifugation between densities 1.019 and 1.063 (ref. 3). The beta-lipoprotein preparations were immunochemically pure. Applying techniques similar to those used for the ...

    Description / Table of Contents: Résumé En laboratoire, la planaireDugesia dorotocephala (Woodworth) a été soumise à du temephos (0,001 ppm), fenthion (0,003; 0,0035 et 0,004 ppm), malathion (0,1 ppm), chlorpyrifos (0,001 et 0,004 ppm), methoprene (0,005 ppm) et à du Dimilin® (0,005 ppm) pendant 24 heures sans montrer d'effets immédiats ou différés sur la survie, le comportement et le pouvoir de reproduction asexuée. La tolérance deD. dorotocephala à des concentrations relativement élevées de pesticides et de régulateurs de croissance rend cette planaire intéressante pour la lutte intégrée contre les moustiques. Des observations, ultérieures au traitement, relatives au pouvoir reproducteur des planaires élevées avant l'expérimentation dans de l'eau contenant 1200–1500 ppm de chlorures (planaires du type 1) et 780–870 ppm (planaires du type 2) indiquent que le taux de reproduction asexuée du type 1 est significativement plus élevé que chez le type 2. D'après ces résultats il serait possible de stimuler la reproduction asexuée, donc la production deD. dorotocephala par un traitement avec certains pesticides et régulateurs de croissance et/ou en recourant à des modifications de la salinité de l'eau d'élevage.
    Notes: Abstract In laboratory tests, the planarianDugesia dorotocephala (Woodworth) was exposed to temephos (0.001 ppm), fenthion (0.003, 0.0035 and 0.004 ppm), malathion (0.1 ppm), chlorpyrifos (0.001 and 0.004 ppm), methoprene (0.005 ppm) and Dimilin ® (0.005 ppm) for 24 h without producing recognizable immediate or delayed effects to the viability, behavior, and asexual reproductive capacity of this planarian.D. dorotocephala tolerated relatively high concentrations of the pesticides and growth regulators suggesting their potential for integrated mosquito control. Post-exposure observations concerning the asexual reproductive capacity ofD. dorotocephala that were initially reared in water with a chloride content of 1200–1500 ppm (type 1 planaria) and 780–870 ppm (type 2 planaria) before experimentation indicated that the degree of asexual reproduction of type I planaria was significantly greater than was observed with type 2 planaria. These results would indicate the possibility of artificially stimulating asexual reproduction, hence mass production by stressingD. dorotocephala in some pesticides and growth regulators and/or by subjecting them to changes in chloride or salinity levels.

    Notes: Abstract The spectral distribution and decay of the blue-green luminescence of AgCl has been measured at very low temperatures, using u.v. laser excitation. A structure was observed in the emission band at 77°K. The decay consists of three processes: a) a very fast process which follows the laser pulse (10−8 sec), b) a fast exponential process which is also observed with low intensity u.v. excitation,(τ∼10−4–10−5 sec) and, finally, c) a slow exponential process (τ∼seconds).
