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

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Lukas Boge; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hexosome; antimicrobial peptide; cubosome; proteolysis; AMP; liquid crystalline nanoparticles; glycerol monooleate; Liquid crystals;

    Abstract : The development of antimicrobial resistance is a great challenge within the health sector around the world. The demand for new efficient treatments is alarming in order to treat various bacterial infections in the near future. Antimicrobial peptides (AMPs) are a group of novel antibiotics that have gain more and more attraction the past decade. READ MORE

  2. 2. Drugs and polymers in dissolving solid dispersions NMR imaging and spectroscopy

    University dissertation from Stockholm : KTH

    Author : Carina Dahlberg; KTH.; [2010]

    Abstract : The number of poorly water-soluble drug substances in the pharmaceutical pipeline is increasing, and thereby also the need to design effective drug delivery systems providing high bioavailability. One favourable formulation approach is preparation of solid dispersions, where dispersing a poorly water-soluble drug in a water-soluble polymer matrix improves the dissolution behaviour and the bioavailability of the drug.

    Abstract : 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. READ MORE

    Abstract : A new kind of lipid/polymer composite particle, consisting of a biodegradable polymer matrix with well-defined lipid domains, has been created. The lipid used is the water-swelling lipid monoolein (MO), which forms a reversed bicontinuous cubic diamond structure in aqueous solutions. READ MORE
