  1. 21. Alzheimer's disease : uncovering mechanisms for amyloid precursor protein processing and trafficking

    Författare :Saket Milind Nigam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer’s Disease (AD) is a progressive neurodegenerative disorder characterized by impairment of memory and, eventually, by disturbances in cognitive abilities. Brain regions crucial for learning and memory exhibit atrophy, but the underlying mechanisms for neurodegeneration continues to be point of debate. LÄS MER

  3. 22. Modelling of dynamic and quasistatic events with special focus on wood-drying distortions

    Författare :Mats Ekevad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : This thesis deals mainly with computer simulations of wood-drying distortions, especially twist. The reason for this is that such distortions often appear in dried timber, and the results are quality downgrades and thus value losses in the wood value chain. LÄS MER

  4. 23. Cellular receptors for viruses with ocular tropism

    Författare :Emma C Nilsson; Niklas Arnberg; Eric J Kremer; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; picornavirus; receptors; antivirals; Virology; Virologi; molekylärbiologi; Molecular Biology; Infectious Diseases; infektionssjukdomar; mikrobiologi; Microbiology;

    Sammanfattning : Several viruses from different virus families are known to cause ocular infections, e.g. members of the Adenoviridae, Picornaviridae and the Herpesviridae families. These infections are spread by contact and in the case of adenoviruses (Ads) and picornaviruses they are also highly contagious. LÄS MER

  5. 24. The effect of Gal alpha(1,3)gal glycopeptide-conjugates and human serum on HIV-1 infection and replication

    Författare :Maria Fernanda Perdomo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The first step in the entry of HIV-1 is the binding of the viral envelope glycoprotein (gp120) to the CD4 molecule expressed mainly on T helper cells. Upon binding, gp120 undergoes a series of conformational changes that expose inner epitopes, which in turn facilitate binding to the viral co-receptors (CCR5 or CXCR4). LÄS MER

  7. 25. Flame-Retardant Cellulose Fibre/Fibril Based Materials via Layer-by-Layer Technique

    Författare :Oruc Koklukaya; Lars Wågberg; Gero Decher; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flame-retardant; cellulose fibre; cellulose nanfibril; layer-by-layer technique; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : According to an analysis conducted by the Swedish Chemicals Inspectorate in 2006, the approximate numbers of fire injuries per year in Sweden are 100 deaths, 700 major and 700 minor injuries.1 Observations also show that there has been an increase in the number of house fires during recent years.
