  1. 21. On HIV-1 infection in the central nervous system

    Författare :Åsa Mellgren; Göteborgs universitet; []
    Nyckelord :HIV-1; antiretroviral therapy; cerebrospinal fluid; neurofilament protein; AIDS dementia complex; neuropsychological test;

    Sammanfattning : HIV-1 (hereafter referred to as HIV) is a neurotropic virus that invades the central nervous system (CNS). The CNS is then susceptible to an acute infection and later to CNS opportunistic diseases and AIDS dementia complex (ADC). HIV does not infect the neurons, and neuropathogenesis is largely mediated by the immune system. LÄS MER

  3. 22. Networks of urban interaction - Growth and centrality in the complex geography of urban activity

    Författare :Alexander Hellervik; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; accessibility; power law; urban activity; centrality; urban growth; transport infrastructure; spatial interaction; complex networks; Zipf’s law;

    Sammanfattning : How cities and regions grow and decline depend on technological, social and economic factors. Understanding the interplay of these forces is central in research efforts aiming to improve urban and transport planning. LÄS MER

  4. 23. Pathophysiological effects of alpha-synuclein on SNARE complex proteins in models of alpha-synucleinopathies

    Författare :Emma Brolin; Joakim Bergström; Anna Erlandsson; Martin Ingelsson; Arianna Bellucci; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alpha-synuclein; Parkinson’s disease; synaptosome; SNARE complex; proximity ligation assay; extracellular vesicles;

    Sammanfattning : Accumulation and spread of alpha-synuclein (α-syn) aggregates are central to the disease pathogenesis of Parkinson’s disease and dementia with Lewy bodies, collectively known as α-synucleinopathies. Native α-syn is a monomeric presynaptic protein that can act as a molecular chaperone for the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex assembly. LÄS MER

  5. 24. Testing Tectonic Concepts in the Seve Nappe Complex, Jämtland, Sweden

    Författare :Hagen Bender; Uwe Ring; Bjarne Almqvist; Karin Högdal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Caledonian orogeny; Seve Nappe Complex; Kinematic analysis; Geology; geologi;

    Sammanfattning : When continental plates collide, one of the involved continents is subducted beneath the other one. As a consequence, the lithosphere thickens along the convergent plate boundary and causes the formation of a mountain belt. LÄS MER

  7. 25. The Alnö alkaline and carbonatitic complex, east central Sweden - a petrogenetic study

    Författare :Jaana Hode Vuorinen; Alasdair Skelton; Ulf Hålenius; Stefan Claesson; Ian Parsons; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbonatite; alkaline; Alnö; geochemistry; isotope; Earth sciences; Geovetenskap;

    Sammanfattning : The Alnö complex on the central Swedish east coast is composed of a main composite intrusion (the main intrusion) and four smaller satellite intrusions (Söråker, Sälskär, Långharsholmen and Båräng) distributed around the main intrusion on Alnö Island and on the mainland north of the island. The major rock types exposed within the complex are melilitolite, pyroxenite, ijolite series (melteigite-ijolite-urtite), nepheline syenite, carbonatite and alnöite dykes. LÄS MER
