  1. 1. Biomedical and atmospheric applications of optical spectroscopy in scattering media

    Författare :Johannes Swartling; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Turbid media; Tissue optics; Tissue optical properties; Multiple scattering; Radiative transfer; Diffusion equation; Monte Carlo method; Time-resolved spectroscopy; Atomic and molecular physics; Integrating spheres; Atom- och molekylärfysik; Fysicumarkivet A:2002:Swartling;

    Sammanfattning : Spectroscopic analysis of scattering media is difficult because the effective path length of the light is non-trivial to predict when photons are scattered many times. The main area of research for such conditions is biological tissues, which scatter light because of variations of the refractive index on the cellular level. LÄS MER

  3. 2. The influence of temperature on enzyme selectivity in organic media

    Författare :Åsa Jönsson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water activity; sub-zero temperatures; enantioselectivity; peptide yields; asymmetric reductions of ketones; peptide synthesis; ADH from Thermoanaerobium brockii; subtilisin; Enzyme catalysis; a-chymotrypsin; organic solvent; aqueous media; Biotechnology; Bioteknik;

    Sammanfattning : The influence of different reaction parameters on enzyme selectivity was investigated. The reaction conditions studied were solvent dependence, water activity and reaction temperature. LÄS MER

  4. 3. On the Use of Ultrasound Phase Data for Arterial Characterization

    Författare :Tobias Erlöv; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atherosclerosis; Ultrasound; Carotid Artery; Plaque Characterization; Scatter Size; Longitudinal Movement; Intima-Media Thickness;

    Sammanfattning : Atherosclerosis is one of the major causes of death in the world. It is an inflammatory disease in the arteries which causes a gradual increase in arterial wall thickness and stiffness. Eventually a plaque could be formed, protruding into the artery and partially occluding the blood flow. LÄS MER

  5. 4. Regulatory Immune Responses and Repair Mechanisms in Atherosclerosis

    Författare :Sara Rattik; Kardiovaskulär forskning - immunitet och ateroskleros; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atherosclerosis; Cardiovascular disease; T helper 2 cells; ApoB100; Regulatory B cells; Regulatory T cells; Smooth muscle cells; IL-22.;

    Sammanfattning : Atherosclerosis is a chronic inflammatory disease characterized by the formation of lipid rich plaques in the arterial wall. Rupture of a plaque results in clinical manifestations such myocardial infarction or stroke. LÄS MER

  7. 5. Lipid-based liquid crystals as drug delivery vehicles for antimicrobial peptides

    Författare :Lukas Boge; Martin Andersson; Lovisa Ringstad; RISE; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Liquid crystals; liquid crystalline nanoparticles; cubosome; hexosome; phase behavior; antimicrobial peptide; AMP; glycerol monooleate; proteolysis; antimicrobial effect; antimicrobial resistance; bacterial membrane; membrane interaction; infection; topical delivery; pulmonary delivery;

    Sammanfattning : The development of antimicrobial resistance is a great challenge within health sectors worldwide. Thus, demand for new, efficient treatments is urgent in order to treat various bacterial infections. Antimicrobial peptides (AMPs) are a group of antibiotics that have gained more and more attraction in the past decade. LÄS MER
