  1. 1. Investigating nano-scale viscous and elastic forces withintermodulation : Studies in multifrequency atomic force microscopy

    Författare :Per-Anders Thorén; David B. Haviland; Greg Haugstad; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic Force Microscopy; Nonlinear dynamics; Soft materials; High- speed friction measurements; Modeling and numerical simulations; Fysik; Physics;

    Sammanfattning : Investigating visco-elastic forces at the nanometer-scale is important to thecharacterization of soft materials. A quantitative force measurement can be ob-tained using an atomic force microscope (AFM) with a calibrated force transducer(the AFM cantilever). LÄS MER

  3. 2. Membrane Interactions of Arginine-Rich Peptides for the Intracellular Delivery of Gene-Targeted Drugs

    Författare :Per Thoren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellular uptake; translocation; protein transduction; circular dichroism; drug delivery; liposomes; resonance energy transfer; PNA; antigene; antisense;

    Sammanfattning : A major obstacle for the therapeutic use of e.g. oligonucleotides is their inherently poor cellular uptake. A recently discovered class of peptides, denoted cell-penetrating peptides, has been shown to traverse cell membranes, even when conjugated to oligonucleotides or even full-length proteins. LÄS MER

  7. 5. The Role of Kit and Thrombopoietin in Regulation of Hematopoietic Stem Cells

    Författare :Lina Thorén; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thrombopoietin; hematopoiesis; Thpo; c-kit; stem cells;

    Sammanfattning : The hematopoietic stem cell (HSC) is postulated to be the ultimate hematopoietic precursor providing production of mature blood cells, and is characterized by a life long capacity for self-renewal and multilineage differentiation. In a healthy human, the HSC produces 1,000,000,000,000 cells per day, illustrating the high turnover within the hematopoietic system and the need for replenishments by HSCs. LÄS MER
