    THREE NATURAL ZIRCON STANDARDS FOR U-TH-PB, LU-HF, TRACE ELEMENT AND REE ANALYSES (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Geostandards and geoanalytical research 19 (1995), S. 0

    Notes: We report here the results of a study to develop natural zircon geochemical standards for calibrating the U-(Th)-Pb geochronometer and Hf isotopic analyses. Additional data were also collected for the major, minor and trace element contents of the three selected sample sets. A total of five large zircon grains (masses between 0.5 and 238 g) were selected for this study, representing three different suites of zircons with ages of 1065 Ma, 2.5 Ma and 0.9 Ma. Geochemical laboratories can obtain these materials by contacting Geostandards Newsletter.

    Developmental effects of 24-epibrassinolide in excised roots of tomato grown in vitro (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 87 (1993), S. 0

    Notes: The effects of 1 pM–10 μM 24-epibrassinolide presented to apical and basal regions of excised roots of tomato (Lycopersicon esculentum Mill. cv. Best of All) grown aseptically in a two-well culture vessel have been investigated. Only inhibitory effects were observed and only at 0. 1 μM or greater. At 10 μM basally- and apically-applied epibrassinolide inhibited growth in apical regions, but not in basal regions. Lower concentrations (1 and 0. 1 μM) also inhibited growth, again only in apical regions and usually only when presented directly to those regions. Cultured tomato roots therefore appear to transport epibrassinolide acropetally, but whether they do so basipetally is not yet clear. The reduced responsiveness to epibrassinolide observed in roots grown by this method is thought to be due to the larger inoculum used rather than the physiological age of the roots. There was some evidence that the sensitivity of cultured roots to epibrassinolide is directly related to growth rate

    Resolving International Conflict: What Role for Business? (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Business strategy review 7 (1996), S. 0 
    Details
    ISSN: 1467-8616
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Economics
    Notes: This second 1996 Stockton Lecture focuses on poverty as a cause of international conflict - and on what businesses can do or avoid doing to reduce it. Poverty, Roddick argues, fuels revolution. And while the western armaments industry is especially to blame, big institutions like the World Bank and the multinationals have all contributed to causing conflict. Her answers to the problem include more “microenterprise” and fair trading initiatives by multinationals in local communities in the developing world. Her central message is that business “must not only avoid hideous evil; it must actively do good”.

    Effect of steroidal glycoalkaloids of the potato on the permeability of liposome membranes (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 68 (1986), S. 0 
    Details
    ISSN: 1399-3054

    Topics: Biology
    Notes: At pH 7.2, the potato glycoalkaloid α-chaconine caused release of entrapped peroxidase from phosphatidylcholine liposomes containing different free sterols but was ineffective against sterol-free liposomes. The alkaloid was able to complex with all the tested sterols in vitro although there was no close correlation between the extent of sterol binding and liposome disruption. α-Solanine also complexed with sterols in vitro but had no effects on sterol-containing liposomes under these conditions. Both sterol concentration and alkaloid concentration were limiting factors in the action of chaconine but did not markedly affect that of solanine. Solanine destabilized liposome membranes only at pH values of 8 and above but was less effective than chaconine. The importance of the carbohydrate moiety of glycoalkaloids was further demonstrated by the inability of β2-chaconine to complex with sterols or disrupt liposomes.

    Comparison of the effects of epibrassinolide and steroidal estrogens on adventitious root growth and early shoot development in mung bean cuttings (1988)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 73 (1988), S. 0

    Topics: Biology
    Notes: Concentrations of 24-epibrassinolide as low as 0.1 μM consistently inhibited adventitious root formation and elongation in both hypocotyl and epicotyl cuttings from mung bean (Phaseolus aureus L.). Similar, but less pronounced, inhibitory effects on root elongation were also observed with estrone sulphate and estradiol sulphate. With regards to root number, estrone sulphate enhanced this in both types of cutting, whereas estradiol sulphate was stimulatory in hypocotyl cuttings but inhibitory in epicotyl cuttings. Brassinolide caused a marked stimulation of epicotyl (but not hypocotyl) elongation and a swelling and splitting of the epicotyl in both types of cutting, whereas estrogens varied in their effect from inhibition of epicotyl growth to no effect. Root-applied brassinolide and estrogen sulphates brought about similar morphological abnormalities in shoots viz. epinasty and inrolling of primary leaves and delayed expansion of the first trifoliate leaf.

    Epibrassinolide-inhibition of development of excised, adventitious and intact roots of tomato (Lycopersicon esculentum): comparison with the effects of steroidal estrogens (1988)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 74 (1988), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The brassinosteroid, 24-epibrassinolide, caused observable inhibition of the growth of aseptically-cultured excised tomato (Lycopersicon esculentum Mill. cv. Best of All) roots at a concentration of 0.01 μM. Root formation and outgrowth in tomato shoot cuttings and root biomass in intact tomato seedlings were also depressed by epibrassinolide, but only at a higher concentration (0.1μM). Concentrations of the steroidal estrogens, estrone and estradiol (as sulphate derivatives), in excess of 1.0 μM, reduced cultured root growth as well as root number and total (but not mean) root length in shoot cuttings. Seedling root growth was only slightly inhibited by estradiol but not by estrone. Both epibrassinolide and estrogens caused morphological abnormalities, such as epinasty and leaf-inrolling in cuttings and seedlings. Epibrassinolide stimulated extension growth of the hypocotyl and epicotyl in cuttings and of the hypocotyl in seedlings, but estrogens exerted no effects on shoot growth.
