  • Antibacterial free fatty acids : activities, mechanisms of action and biotechnological potential 

    Desbois, Andrew Paul; Smith, Valerie Jane (2010-02) - Journal article
    Amongst the diverse and potent biological activities of free fatty acids (FFAs) is the ability to kill or inhibit the growth of bacteria. The antibacterial properties of FFAs are used by many organisms to defend against ...

    The aim of this thesis was to isolate the compounds responsible for the antibacterial activity of cell extracts of the marine diatom, Phaeodactylum tricornutum. Marine microalgae are not only important primary producers ...
  • Antibodies for immunolabeling by light and electron microscopy : not for the faint hearted 

    Griffiths, Gareth; Lucocq, John Milton (2014-10) - Journal item
    Reliable antibodies represent crucial tools in the arsenal of the cell biologist and using them to localize antigens for immunocytochemistry is one of their most important applications. However, antibody-antigen interactions ...
  • Anticipation, learning and welfare : the case of distortionary taxation 

    Gasteiger, Emanuel; Zhang, Shoujian (University of St Andrews, 2013-08-26) - Working or discussion paper
    We study the impact of anticipated fiscal policy changes in a Ramsey economy where agents form long-horizon expectations using adaptive learning. We ex- tend the existing framework by introducing distortionary taxes as ...

    Kouneni, Garyfallia (University of St Andrews, 2009-06-25) - Thesis

  • Antitrust penalties and the implications of empirical evidence on cartel overcharges 

    Katsoulacos, Yannis; Ulph, David Tregear (2013-11) - Journal article
    In this paper we provide a number of extensions to the theory of antitrust fines and we use these, with existing and new datasets, to contribute to a better understanding of the current fining policies of Competition ...
  • Antitumour activity of the novel flavonoid oncamex in preclinical breast cancer models

    Background: The natural polyphenol myricetin induces cell cycle arrest and apoptosis in preclinical cancer models. We hypothesised that myricetin-derived flavonoids with enhanced redox properties, improved cell uptake and ...
  • Antrim Area Hospital wind turbine 

    Sustainable Development Commission (Sustainable Development Commission, 2006-10) - Report
    Antrim Area Hospital in Northern Ireland is on track to save £90,000 a year in energy costs by generating its own wind power, to the benefit of patients and the environment.
  • Ants as flower visitors : floral ant-repellence and the impact of ant scent-marks on pollinator behaviour 

    Ballantyne, Gavin (University of St Andrews, 2011-11) - Thesis
    As flower visitors, ants rarely benefit a plant, commonly disrupting pollination by deterring other flower visitors, or stealing nectar. This thesis examines three aspects of ant-flower interactions, focusing on the ...
  • Anxiety reduction via brief intervention in dentally anxious patients : a randomized controlled trial 

    Hull, P; Humphris, Gerald Michael (2010-12) - Journal article
    Aim: To compare the degree of anxiety reduction in dentally anxious patients attending a Dental Access Centre where the dentist did or did not receive the patients’ assessment of dental anxiety. Methods: Patients attending ...
  • APE-type non-LTR retrotransposons of multicellular organisms encode virus-like 2A oligopeptide sequences, which mediate translational recoding during protein synthesis 

    Odon, Valerie Marie Nathalie; Luke, Garry Alec; Roulston, Claire; De Felipe, Pablo; Ruan, Lin; Escuin, Helena; Brown, Jeremy; Ryan, Martin Denis; Sukhodub, Andriy (2013-08) - Journal article
    2A oligopeptide sequences (“2As”) mediate a cotranslational recoding event termed “ribosome skipping.” Previously we demonstrated the activity of 2As (and “2A-like sequences”) within a wide range of animal RNA virus genomes ...
  • Apes have culture but may not know that they do 

    Gruber, Thibaud; Zuberbuehler, Klaus; Clement, Fabrice; van Schaik, Carel (2015-02-06) - Journal article
    There is good evidence that some ape behaviors can be transmitted socially and that this can lead to group-specific traditions. However, many consider animal traditions, including those in great apes, to be fundamentally ...
  • Apes in the Anthropocene : flexibility and survival 

    Hockings, Kimberley J.; McLennan, Matthew R.; Carvalho, Susana; Ancrenaz, Marc; Bobe, René; Byrne, R.W.; Dunbar, Robin I.M.; Matsuzawa, Tetsuro; McGrew, William C.; Williamson, Elizabeth A.; Wilson, Michael L.; Wood, Bernard; Wrangham, Richard W.; Hill, Catherine M. (2015-04) - Journal article
    We are in a new epoch, the Anthropocene, and research into our closest living relatives, the great apes, must keep pace with the rate that our species is driving change. While a goal of many studies is to understand how ...
  • Apicoplast lipoic acid protein ligase B is not essential for Plasmodium falciparum 

    Guenther, Svenja; Wallace, Lynsey; Patzewitz, Eva-Maria; McMillan, Paul J.; Storm, Janet; Wrenger, Carsten; Bissett, Ryan; Smith, Terry K; Mueller, Sylke (2007-12) - Journal article
    Lipoic acid (LA) is an essential cofactor of alpha-keto acid dehydrogenase complexes (KADHs) and the glycine cleavage system. In Plasmodium, LA is attached to the KADHs by organelle-specific lipoylation pathways. Biosynthesis ...
