  1. 1. Amphiphilic Peptide Interactions with Complex Biological Membranes Effect of peptide properties on antimicrobial and anti-inflammatory effects

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Shalini Singh; Uppsala universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LPS; Antimicrobial; Peptide; Inflammation; Infections; Liposome; Binding; PEG; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Sammanfattning : With increasing problem of resistance development in bacteria against conventional antibiotics, as well as problems associated with diseases either triggered or enhanced by infection, there is an urgent need to identify new types of effective therapeutics for the treatment of infectious diseases and its consequences. Antimicrobial and anti-inflammatory peptides have attracted considerable interest as potential new antibiotics in this context. LÄS MER

  2. 2. Biomimetic Formation of Calcium Phosphate Based Nanomaterials

    Sammanfattning : The intercellular material in bone is a nanocomposite of aligned “hard” inorganics—calcium phosphate (CaP) platelets embedded in the long-range ordered “soft” organic collagen matrix. This elaborate structural arrangement redeems the weaknesses of the individual components (being soft protein or brittle mineral) and gives bone its excellent mechanical properties for the protection and support of our bodies.

  3. 3. Functionalization and characterization of surface supported lipid membranes and their application in cell culture

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Dorota Thid; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cell - surface interaction; supported phospholipid bilayer; IKVAV; DHA; stem progenitor cells; neural cells; surface analytical techniques; QCM-D; surface functionalization; peptide; cell differentiation; cell attachment; membrane; fatty acid;

    Sammanfattning : Phospholipid bilayers supported on a solid surface constitute a versatile, biomimetic platform for a variety of applications, such as biosensing, drug delivery research, cell engineering and as cell membrane mimics in fundamental cell research. Phosphocholine supported lipid bilayers are resistant to cell attachment in a wide range of conditions, and can be functionalized with bioactive signaling molecules to promote specific interactions with cells.

  4. 4. Development of lipodisks as carriers for cationic amphiphilic peptides

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Karin Reijmar Brunnström; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Antibiotics have made a tremendous contribution to mankind. They are one of the most successful medicines in human history. However, more and more bacterial strains develop resistance and the risk to public health can hardly be overstated. New types of antibiotics are urgently needed. LÄS MER

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

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Sammanfattning : Många av oss har någon gång blivit tvungna att ta en penicillinkur mot halsfluss eller kanske i samband med någon annan infektion. Oftast har behandlingen varit till stor nytta, och infektioner som förr i tiden kunde leda till döden har varit lätta att behandla med hjälp av antibiotika. LÄS MER
