  1. 6. Autoproteolysis accelerated by conformational strain - a novel biochemical mechanism

    Författare :Denny Johansson; Göteborgs universitet; []
    Nyckelord :SEA domain; autoproteolysis; MUC1; conformational strain; protein folding;

    Sammanfattning : Natural fragmentation of polypeptide chains by autoproteolysis occurs in a number of protein families. It is a vital step in the maturation of several enzymes and in the formation of membrane-associated mucins that constitute a part of the protective mucus barrier lining epithelial cells. LÄS MER

  3. 7. Mediators of synaptic activity in anxiety- and depression-related behaviors

    Författare :Carly Kiselycznyk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Depression and anxiety are leading causes of years lost to disability, despite antidepressants being among the most commonly prescribed medications. Most currently prescribed antidepressants were found serendipitously rather than from an understanding of the biological mechanisms underlying depression. LÄS MER

  4. 8. Synthesis and Reactivity Studies of Zwitterionic Silenes and 2-Silenolates

    Författare :Tamaz Guliashvili; Henrik Ottosson; Kim M. Baines; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Silicon; Zwitterionic Silene; 2-Silenolate; Diels-Alder Reaction; Silacyclohexene; X-ray Crystallography; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis describes synthesis and reactivity studies of 2-amino-2-siloxysilenes and 2-silenolates, species that are strongly influenced by reversed Si=C bond polarization, i.e. an Siδ-=Cδ+ polarization as compared to the natural Siδ+=Cδ- polarization. LÄS MER

  5. 9. Structural Aspects of Halocuprate and Haloargentate Anions in Supramolecular Systems

    Författare :Catrin Hasselgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coordination chemistry; molecular modelling; supramolecular chemistry; haloacuprate; mass spectrometry; density functional theory; haloargentate; intermolecular interactions;

    Sammanfattning : There is a growing interest in designing and engineering crystals of compounds with desired structures and properties. In this context, a better understanding of the intermolecular interactions present in crystals is of importance and much work is currently being directed towards this goal. LÄS MER

  7. 10. The adrenalectomized rat : a model for neurodegeneration

    Författare :Atiqul Islam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The hippocampus is a highly organized laminar structure known to be a focus of damage in several neurodegenerative conditions. This neural structure is a primary target for glucocorticoids and has been strongly implicated in cognitive processes such as learning and memory. LÄS MER
