  1. 1. Cerium Oxide Nanoparticles and Gadolinium Integration : Synthesis, Characterization and Biomedical Applications

    Författare :Peter Eriksson; Kajsa Uvdal; Caroline Brommesson; Xuanjun Zhang; Zhang-Jun Hu; Duncan Sutherland; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A challenging task, in the area of magnetic resonance imaging is to develop contrast enhancers with built-in antioxidant properties. Oxidative stress is considered to be involved in the onset and progression of several serious conditions such as Alzheimer’s and Parkinson’s disease, and the possibility to use cerium-contained nanoparticles to modulate such inflammatory response has gained a lot of interest lately.

  2. 2. The role of virus neutralization in primate lentivirus pathogenesis

    Författare :Yi jun Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : The antiviral neutralizing activity of sera from primate lentivirus-infected human and monkey hosts was studied. In addition, factors affecting the neutralization reaction were investigated. In simian immunodeficiency virus (SIVsm)-infected macaque monkeys, SIVsm variants able to escape neutralization emerged regularly. LÄS MER

  3. 3. Synthesis and characterization of fluorescent stilbene-based probes targeting amyloid fibrils

    Författare :Jun Zhang; Peter Konradsson; Per Hammarström; Xiongyu Wu; Lin Li; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Alzheimer’s disease (AD) is characterized by two main protein aggregate hallmarks in the brain: extracellular deposition of the amyloid-β (Aβ) in senile plaques and intracellular neurofibrillary tangles (NFTs) consisting of hyperphosphorylated tau protein. The past decade has seen great progress in the development of imaging probes for the non-invasive detection of Aβ and tau aggregates. LÄS MER

  4. 4. Integration of metallic source/drain contacts in MOSFET technology

    Författare :Jun Luo; Mikael Östling; Shi-Li Zhang; Anthony O'Neill; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; CMOS technology; MOSFET; Schottky barrier MOSFET; metallic source drain; contact resistivity; NiSi; PtSi; SALICIDE; ultrathin silicide; FinFET; Semiconductor physics; Halvledarfysik;

    Sammanfattning : The continuous and aggressive downscaling of conventional CMOS devices has been driving the vast growth of ICs over the last few decades. As the CMOS downscaling approaches the fundamental limits, novel device architectures such as metallic source/drain Schottky barrier MOSFET (SB-MOSFET) and SB-FinFET are probably needed to further push the ultimate downscaling.

  5. 5. Immunogenicity of and apoptosis modulation by Epstein-Barr virus (EBV)-encoded latent membrane protein-1 (LMP1) : Implications for nasopharyngeal carcinoma

    Författare :Xiangning Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Epstein-Barr virus (EBV) is a ubiquitous human herpesvirus which infects more than 90% of individuals in the population, and has been shown to be associated with a variety of human tumors. The viral genome encodes a number of transforming proteins which enable the virus to efficiently immortalize B lymphocyte and also transform cells of other types. LÄS MER
