    [Auszug] At least 30 different complex-type bi-antennary oligosaccharides are associated with human serum IgG (Fig. 2). To compare the molar proportions of each of these structures, each serum IgG sample was subjected to controlled hydrazinolysis to release intact its associated oligosaccharide moieties11. ...

    Notes:
    Summary The new immunosuppressive agent cyclosporine (Cyclosporin A, Cy) is the most prominent member of a group of cyclic peptide fungal metabolites (cyclosporins) produced byTolypocladium inflatum in submerged fermentations. In the present study, kinetics and physiology of mycelial growth and Cy production byT. inflatum were examined. A new semi-synthetic medium was formulated, consisting of a single carbon/energy source, Bacto-peptone, potassium phosphate and potassium chloride. A wide variety of carbon sources supported growth and Cy production. 3% (w/v) sorbose gave the highest final Cy titer (105.5 mg/l), based on 10-day fermentations. The best specific Cy production was observed with 2% sorbose (14.3 mg Cy/g biomass) followed by 5%myo-inositol (13.4 mg Cy/g biomass). A feeding strategy consisting of sequential addition of two carbon sources such as sorbose and maltose was developed in order to reach higher volumetric production. Genetic studies were also conducted, focussing on the development of mutants for increased Cy production and for the synthesis of novel cyclosporins. In the course of these studies, viable protoplasts ofT. inflatum have been isolated and regenerated.

    Notes:
    Four commercial disperse dyes were purified and their different crystal forms were prepared by crystallizing from different solvents or precipitating from their solutions in glacial acetic acid by dilution with water. These forms were found to have different melting points. They were dyed on polyester fibers at 130°C to fiber saturation values by changing the dyebath every 15 min. The effect of pretreatment of the dyes in an aqueous environment at different temperatures (60°, 100°, and 130°C) for 15-60 min in the presence and absence of a dispersing agent on the dye uptake values was also studied. Such treatments are shown to reduce the dye uptake. The implication of these treatments in practical dyeing are pointed out.

    Notes:
    The thermogravimetry (TGA) in nitrogen was measured for poly(tetramethyl-p-silphenylene)-siloxane (TMPS) fractions with narrow molecular weight distributions and for block copolymers of TMPS and dimethyl siloxane (DMS) with varying composition. The measurements were made with the Perkin-Elmer DCS IB-TGA attachment which consists of a Cahn electrobalance and a wire-wound furnace with programmable temperature controls. The weight loss curves for heating rates of 10, 20, and 40°C/min were analyzed using the method of Flynn and Wall. The analysis indicates that thermal degradation proceeds primarily by scission of the siloxane bond with an activation energy of 44 ± 3 kcal/mole for the uncatalyzed reaction and 13 ± 2 kcal/mole for the reaction occurring in the presence of residual catalyst. The thermal stability of the TMPS-DMS copolymer is impaired through increasing the concentration of the DMS component. Cyclic DMS trimer and TMPS monomer and dimer were observed by mass spectrometry which gave results consistent with the proposed mechanism of degradation.
