  2. 1. Organic complexing agents for remediation of heavy metal contaminated soil

    Author : Zandra Arwidsson; Bert Allard; Mats Åström; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; soil washing; heavy metals; chelators; recycling; NATURAL SCIENCES; NATURVETENSKAP; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Abstract : Soil washing of heavy metal contaminated soil may be enhanced by the addition of synthetic chelators. Since many of these chelators may imply stress to soil organisms and are poorly biodegraded, identification and evaluation of effective biodegradable or recyclable chelators (synthetic and/or naturally produced) is of great interest.

  4. 2. Development of 18F- and 68Ga-Labelled Tracers : Design Perspectives and the Search for Faster Synthesis

    Author : Elisabeth Blom; Bengt Långström; Oleksiy Itsenko; Irina Velikyan; Farhad Karimi; Frank Rösch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PET; nucleophilic 18F-fluorination; perfluoro; F-SPE; molecular design; 68Ga; chelators; DOTA; NOTA; microwave; halogen exchange; harmine; biotin; RGD; VEGF; CRP; Chemistry; Kemi; Organisk kemi; Organic Chemistry;

    Abstract : This thesis deals with the design of 18F- and 68Ga-labelled positron emission tomography (PET) tracers and the development of technologies that enable faster and simpler preparation with high specific radioactivity. Techniques like microwave heating and reducing the concentrations of the precursor were investigated with this perspective. READ MORE

  5. 3. Microbe-mineral interactions in soil : Investigation of biogenic chelators, microenvironments and weathering processes

    Author : Engy Ahmed; Sara Holmström; Roger Finlay; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Podzol; Biotite; Apatite; Oligoclase; Microbial attachment; Siderophores; Soil microorganisms; geokemi; Geochemistry;

    Abstract : The interplay between geology and biology has shaped the Earth during billions of years. Microbe-mineral interactions are prime examples of this interplay and underscore the importance of microorganisms in making Earth a suitable environment for all forms of life. READ MORE

  6. 4. Radiolabelled affibody molecules for imaging EGFR expression in tumours

    Author : Maryam Oroujeni; Vladimir Tolmachev; Martin Behe; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Affibody molecules; ZEGFR:2377; radionuclide molecular imaging; PET; SPECT; labelling chemistry.;

    Abstract : Affibody molecules are promising scaffold-based targeting proteins for radionuclide imaging and cancer therapy. This thesis is based on 5 original research articles (Papers I-V), with the primary focus being placed on the optimization of molecular design of EGFR-binding affibody variants for high contrast imaging of epidermal growth factor receptor (EGFR) expression in tumours.

  7. 5. Oligomerization of human and bacterial frataxin : Structural and functional studies

    Author : Mostafa Abdalkhalik; Biokemi och Strukturbiologi; []
    Keywords : Frataxin; Friedreich’s ataxia; iron; reactive oxiden species; protein oligomerization; SAXS; EM; cross-linking; XAFS; nano- DSF;

    Abstract : Friedreich’s ataxia (FRDA) is an autosomal recessive neurodegenerative disease caused by defeciency in frataxin, a highly conserved protein central to iron homeostasis in mirochondria. The function of frataxin is related to its capability to bind, store and deliver iron to different biochemical process such as iron-sulfur cluster assembly and heme biosynthesis. READ MORE
