    Notes: We report atomic force microscopy images of one-dimensional silicon chains (polysilanes) individually bonded to a substrate surface [quartz glass (SiO2), sapphire (Al2O3), and Si(111)]. The sample was prepared by a one-to-one chemical reaction between a reactive anchor of alkylbromide on the surface and a polysilanyl lithium. We observed dot images with variable densities which depended on the reactive anchor density. Each dot, with a diameter of about 20 nm and a height of about 5 nm, corresponded to an isolated single polysilane molecule with a collapsed structure typical of usual end-grafted polymers under poor solvent conditions. © 1999 American Institute of Physics.

    α-L-FUCOSYLTRANSFERASES RELATED TO BIOSYNTHESIS OF BLOOD GROUP SUBSTANCES IN HUMAN SALIVA (1980)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: α-L-Fucosyltransferases were demonstrated in human saliva which catalyze the transfer of L-fucose from GDP-L-[14C]-fucose to oligosaccharides from human milk. An α-(1→4)-L-fucosyltransferase that synthesizes lacto-N-fucopentaose II and lacto-N-difucohexaose I from lacto-N-tetraose and lacto-N-fucopentaose I, respectively, was detected in saliva samples of Le(a-b+) secretors and Le(a + b-) non-secretors in which Lea substance was secreted. This enzyme activity was demonstrable neither in saliva samples of Le(a-b-) secretors nor non-secretors. An α-(1→2)-L-fucosyltransferase, that synthesizes lacto-N-fucopentaose I from lacto-N-tetraose, was detected in saliva samples from Le(a-b+) secretors which secreted H and Leb substances and from Le(a-b-) secretors which secreted only H substance. An α-(1→3)-L-fucosyltransferase was present in all saliva samples of different ABO and Lewis blood groups, irrespective of their ABH secretor status of the donors. The fucosyltransferases in saliva were activated by Mn++ or Mg++ ions, and were inhibited by ATP, GTP and EDTA. They had a broad pH optimun between pH 5.0 and 6.5.

    Mobilities of Li+ in Ne and in N2 and Na+ in SF6: Effect of inelastic energy loss (1996)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 105 (1996), S. 3031-3034

    Topics: Physics , Chemistry and Pharmacology
    Notes: Ion mobility measurements were made for Li+ in Ne and in N2 and Na+ in SF6 using a variable-temperature drift tube. The measurements were made by two different methods: variable-E/N method at constant T and variable-T method at constant E/N, where E, N, and T are the electric field strength, the gas number density, and the gas temperature, respectively. Two datasets were compared at the same effective temperature Teff, as calculated from the Wannier equation. For Li+ in Ne, the two datasets are put on a single curve in the range 150 K〈Teff〈10 000 K, indicating that the scaling rule holds well. However, for Li+ in N2 and Na+ in SF6 there exists a mobility difference between the two datasets, which is attributed to inelastic energy loss in the variable-E/N measurement. Using the modified Wannier equation developed by Viehland et al., we determined the inelastic energy loss factor for Na+ in SF6. © 1996 American Institute of Physics.

    Notes: α-Galactosyltransferase which participates in the biosynthesis of blood group B substance was found in urine from group B and AB healthy persons of both secretors and non-secretors.The activity of α-galactosyltransferase in the urine of healthy variant Bm person was lower than that found in a normal group B person. This enzyme in urine of A1Bm persons must be much lower than that in normal AB persons. Its activity was not detected by the method of group O to group B transformation of erythrocytes.

    IMMUNOCHEMICAL PROPERTIES OF HUMAN PLASMA α1 → 2 FUCOSYLTRANSFERASE SPECIFIED BY BLOOD GROUP H-GENE (1983)
    Oxford, UK : Blackwell Publishing Ltd
    International journal of immunogenetics 10 (1983), S. 0

    Notes: A β-galactoside α1 → 2 fucosyltransferase (H-enzyme) from human group O plasma which provides H blood group specificity to erythrocyte membranes has been purified approximately 22,000-fold by chromatography on DEAE-Sepharose CL-6B, GDP-hexanolamine-Sepharose 4B and SP-Sephadex C-50. The molecular weight of the H-enzyme was estimated to be 150,000 by gel filtration. Human group O erythrocyte membranes which had lost their H blood group activity by the action of α1 → 2 fucosidase were fucosylated by the transferase, and restored the H activity. Radioactive L-fucose appeared to be incorporated into glycolipid blood group substances of erythrocyte membranes. The activity of the α1 → 2 fucosyltransferase from human plasma, stomach mucosa, erythrocyte membranes and porcine stomach mucosa were specifically inhibited by the rabbit antiserum immunized with the preparation of human plasma H-enzyme. The anti-plasma H-enzyme antiserum did not inhibit the activities of α1 → 3 N-acetygalactosaminyltransferase (A-enzyme), α1 → 3 galactosyltransferase (B-enzyme), and β-N-acetylglucosaminide α1 → 3 and α1 → 4 fucosyltransferases from human plasma and stomach mucosa.

    γ-Mangostin, a novel type of 5-hydroxytryptamine 2A receptor antagonist (1997)
    Springer

    ISSN: 1432-1912
    Keywords: Key wordsγ-Mangostin ; 5-Hydroxytryptamine ; 5-Hydroxytryptamine 2A receptor antagonist ; Rabbit aorta ; Rat coronary ; Rabbit platelet

    Notes: Abstract γ-Mangostin, purified from the fruit hull of the medicinal plant Garcinia mangostana caused a parallel rightwards shift of the concentration/response curve for the contraction elicited by 5-hydroxytryptamine (5-HT) in the rabbit aorta (pA2 = 8.2) without affecting the contractile responses to KCl, phenylephrine (α1) or histamine (H1). The perfusion pressure response of rat coronary artery to 5-HT (5-HT2A) was reduced concentration dependently by γ-mangostin (IC50 = 0.32 μM). 5-HT amplified, ADP-induced aggregation of rabbit platelets (5-HT2A) was inhibited by γ-mangostin (IC50 = 0.29 μM), whereas that induced by thrombin was not affected, nor did γ-mangostin affect 5-HT-induced contraction of the guinea-pig ileum (5-HT3)in the presence of 5-HT1, 5-HT2 and 5-HT4 receptor antagonists. Furthermore, 5-HT-induced contraction of the rat fundus (5-HT2B) and 5-HT-induced relaxation of the rabbit aorta in the presence of ketanserin (5-HT1) and carbachol-induced contraction of the guinea-pig ileum (muscarinic M3) were not affected by γ-mangostin (5 μM). γ-Mangostin inhibited [3H]spiperone binding to cultured rat aortic myocytes (IC50 = 3.5 nM). The K d for [3H]spiperone binding was increased by γ-mangostin (3 nM) from 11.7 to 27.4 nM without affecting B max. These results suggest that γ-mangostin is a novel competitive antagonist, free from a nitrogen atom, for the 5-HT2A receptors in vascular smooth muscles and platelets.

    Notes: Abstract A laboratory upflow anaerobic sludge blanket reactor, seeded with fine, suspended, bacterial floc with 1.76 g volatile suspended solids/l, was used to treat synthetic methanolic waste. After 180 days of continuous peration, granular sludge with discrete granules of 1 to 2 mm diam. was formed, with 52 g volatile suspended solids/l. Granules were brown, relatively soft and had a settling velocity of 1.61 cm/s. Extracellular polymeric matter extracted from the granular sludge had high carbohydrate content but low nucleic acid content. The ash of the granular sludge contained Na+, K+ and Mg2+ up to 15.0, 11.7 and 3.75 mg/g, respectively. Scanning and transmission electron microscopy revealed that the granular sludge was dominated by methanogens resembling Methanosarcina.
