    Mackinnon, L. Jay (University of St Andrews, 2007-06) - Thesis
    Isoflavones are biologically active plant chemicals (phytoestrogens) which are ordinarily present in human diets. There is considerable research interest in their potential to prevent or treat several chronic diseases. ...
  • Biomass recycling and Earth's early phosphorus cycle 

    Kipp, Michael; Stueeken, Eva Elisabeth (2017-11-22) - Journal article
    Phosphorus sets the pace of marine biological productivity on geological time scales. Recent estimates of Precambrian phosphorus levels suggest a severe deficit of this macronutrient, with the depletion attributed to ...
  • Biomineralisation during operculum regeneration in the polychaete Spirobranchus lamarcki 

    Szabo, Reka; Calder, Angus; Ferrier, David Ellard Keith (2014-11) - Journal article
    Formation of calcified biominerals is widespread in marine animals and is often associated with important elements of their biology, such as support and protection. Serpulid polychaetes are relatively understudied examples ...
  • Biophysical aspects of photodynamic therapy 

    Valentine, Ronan (University of St Andrews, 2011-11-30) - Thesis
    Photodynamic therapy (PDT) is a multimodality cancer treatment available for the palliation or eradication of systemic and cutaneous malignancies. In this thesis, the application of PDT is for the treatment of non-melanoma ...
  • Biosocial selfhood : overcoming the ‘body-social problem’ within the individuation of the human self 

    Higgins, Joe (2017-06-10) - Journal article
    In a recent paper, Kyselo (2014) argues that an enactive approach to selfhood can overcome ‘the body-social problem’: “the question for philosophy of cognitive science about how bodily and social aspects figure in the ...
  • Biosonar performance of foraging beaked whales (Mesoplodon densirostris) 

    Madsen, P T; Johnson, M; de Soto, N A; Zimmer, W M X; Tyack, P (2005-01-15) - Journal article
    Toothed whales (Cetacea, odontoceti) emit sound pulses to probe their surroundings by active echolocation. Noninvasive, acoustic Dtags were placed on deep-diving Blainville's beaked whales (Mesoplodon densirostris) to ...
  • Biosynthesis of magnetic nanoparticles by human mesenchymal stem cells following transfection with the magnetotactic bacterial gene mms6 

    Elfick, Alistair; Rischitor, Grigore; Mouras, Rabah; Azfer, Asim; Lungaro, Lisa; Uhlarz, Marc; Herrmannsdörfer, Thomas; Lucocq, John Milton; Gamal, Wesam; Bagnaninchi, Pierre; Semple, Scott; Salter, Donald M. (2017-01-04) - Journal article
    The use of stem cells to support tissue repair is facilitated by loading of the therapeutic cells with magnetic nanoparticles (MNPs) enabling magnetic tracking and targeting. Current methods for magnetizing cells use ...
  • Biparental incubation-scheduling : no experimental evidence for major energetic constraints 

    Bulla, M; Cresswell, Will; Rutten, A; Valcu, M; Kempenaers, B (2015) - Journal article
    Incubation is energetically demanding, but it is debated whether these demands constrain incubation-scheduling (i.e., the length, constancy, and timing of incubation bouts) in cases where both parents incubate. Using 2 ...
  • Bipolar conductance switching of single anthradithiophene molecules 

    Borca, Bogdana; Schendel, Verena; Petuya, Remi; Pentegov, Ivan; Michnowicz, Tomasz; Kraft, Ulrike; Klauk, Hagen; Arnau, Andres; Wahl, Peter; Schlickum, Uta; Kern, Klaus (2015-12-22) - Journal article
    Single molecular switches are basic device elements in organic electronics. The pentacene analogue anthradithiophene (ADT) shows a fully reversible binary switching between different adsorption conformations on a metallic ...
  • Bird species richness and diversity at montane Important Bird Area (IBA) sites in south-eastern Nigeria 

    Manu, S; Imong, I. S.; Cresswell, Will (2010-09) - Journal article
