  1. 1. Regulation of Proton Coupled Electron Transfer from Amino Acids in Artificial Model Systems: A Mechanistic Study

    Författare :Martin Sjödin; Leif Hammarström; Jan Davidsson; G. Daniel Nocera; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Proton Coupled Electron Transfer; Tyrosine; Tryptophan; Electron Transfer; Hydrogen bond; Photosystem II; Proton transfer; Radical protein; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Amino acid radicals are key redox intermediates in several natural enzymes including Cytochrome c peroxidase, DNA photolyase, ribonucletide reductase, cytochrome c oxidase and photosystem II. Electron transfer from amino acids is often coupled to deprotonation and this thesis concerns the coupling of electron transfer from tyrosine and tryptophan to trisbipyridineruthenium(III) with deprotonation in model complexes.

  2. 2. Insiders’ outside/Outsiders’ inside : Rethinking the insider regulation

    Författare :Ulrika Sjödin; Thomas Bay; Pierre Guillet de Monthoux; Elton G. McGoun; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Financial trade; speculation; insider trading; insider regulation; market professionals; law; game rule; gambling; economy; financial markets; desire; investment; risk; symmetric information; genealogy; deconstruction; Business studies; Företagsekonomi;

    Sammanfattning : Financial speculation has increased dramatically over the last 30 years. This means that a practice that used to be viewed as immoral gambling has become legitimate financial trade. This book explores the genealogy of the coexisting insider trading laws. LÄS MER

  3. 3. Evaluation of the Endo-Lysosomal System and the Ubiquitin-Proteasome System in Neurodegenerative Diseases

    Författare :Simon Sjödin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; Parkinson’s disease; frontotemporal dementia; dysfunctional proteostasis; cerebrospinal fluid; mass spectrometry;

    Sammanfattning : Neurodegeneration is the process of neuronal cell loss where the symptoms will reflect the regions affected. Neurodegenerative disorders including Alzheimer’s disease (AD), Parkinson’s disease (PD) and frontotemporal dementia (FTD) are all characterised by an accumulation of protein aggregates suggesting impaired production or turnover of these proteins.

  4. 4. Resonant multi-photon ionisation studies of high-energy states in small molecules

    Författare :Marica Sjödin; Lars-Erik Berg; Arne Rosén; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : This thesis describes separate studies of high-energy Rydberg and ion-pair states in small molecules using resonant multi-photon ionisation spectroscopy. * OODR/REMPI study of ungerade Rydberg states in O2 The energy region between 75000 and 99900 cm-1 of O2 has been studied using optical-optical double resonance (OODR) with resonance enhanced multi-photon ionisation (REMPI).

  5. 5. Pharmacological Studies of Four Neuropeptide Y-family Receptor Subtypes

    Författare :Paula Sjödin; Dan Larhammar; Nina Mohell; Nigel Levens; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Sammanfattning : The neuropeptide Y (NPY) family of structurally related peptides includes NPY, peptide YY (PYY) and pancreatic polypeptide (PP). They bind to G-protein coupled receptors named Y receptors, and include in mammals Y1, Y2, Y4, Y5, Y6 and in non-mammalian vertebrates also Y7, Yb and Yc. LÄS MER
