  1. 1. Drug Eluting Hydrogels : Design, Synthesis and Evaluation

    Author : Lage Ahrenstedt; Deon Bezuidenhout; Michael Malkoch; University of Cape Town; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drug delivery; PEGylation; Rapamycin; Dexamethasone; Controlled release; Hydrogels; Slow release;

    Abstract : Hydrogels have successfully proved themselves useful for drug delivery applications and several delivery routes have been developed over the years. The particular interest in this work was to design, synthesise and evaluate in situ forming drug eluting hydrogels, which have the potential to ameliorate the healing of cardiovascular diseases.

  2. 2. Structural studies of drug targets and a drug metabolizing enzyme

    Author : Daniela Cederfelt; U. Helena Danielson; Doreen Dobritzsch; Inari Kursula; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biophysics; Protein structure; X-ray crystallography; Cryogenic electron microscopy; Enzymology; Drug discovery; Pyrimidine degradation; Biokemi; Biochemistry;

    Abstract : The work presented in this thesis describes how structural information about a protein can be acquired, and how it can be used to answer scientific questions about proteins’ function, their dynamic behaviour and their interactions with other proteins or ligands.The catalytic function of the pyrimidine-degrading, drug metabolizing enzyme β-ureidopropionase (βUP) is dependent on the shift between oligomeric states.

  3. 3. Development and Evaluation of Lipodisks Intended for Use as Biomimetic Membranes and Drug Carriers

    Author : Malin Morin Zetterberg; Katarina Edwards; Jonas Bergquist; Ana Maria Carmona-Ribeiro; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; model membranes; drug delivery; drug partitioning; antimicrobial peptides; nanocarriers; cryo-TEM; polymer-stabilized bilayer disks; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : Polyethylene glycol-stabilized lipodisks have emerged as a novel type of lipid-based nanoparticles with high potential as both drug carriers and biomimetic membranes. In this thesis we assess both of these applications, and show how the properties of the lipodisks can be further developed and optimized. READ MORE

  4. 4. In vitro and in silico Predictions of Hepatic Transporter-Mediated Drug Clearance and Drug-Drug Interactions in vivo

    Author : Anna Vildhede; Per Artursson; Maria Karlgren; Maria Kjellsson; Ulf Norinder; Kim Brouwer; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; OATP1B1; OATP1B3; OATP2B1; NTCP; drug transporters; human hepatocytes; atorvastatin; pitavastatin; proteomics; sandwich-cultured human hepatocytes; SCHH; mechanistic modeling; in vitro-in vivo extrapolation; transport inhibition; hepatic uptake; hepatocyte isolation; transporter contribution; Biopharmaceutics; Biofarmaci;

    Abstract : The liver is the major detoxifying organ, clearing the blood from drugs and other xenobiotics. The extent of hepatic clearance (CL) determines drug exposure and hence, the efficacy and toxicity associated with exposure. Drug-drug interactions (DDIs) that alter the hepatic CL may cause more or less severe outcomes, such as adverse drug reactions. READ MORE

  5. 5. Bacteria-responsive materials for drug delivery

    Author : Marina Craig; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; triggered release; multilayer; controlled release; Layer-by-layer; nanofilm; infection; enzymatic degradation;

    Abstract : The number of diabetics, obese individuals and other patients carrying other lifestyle diseasesis increasing worldwide. At the same time the population is ageing. These patients all sufferfrom poor blood circulation, which often gives rise to non-healing, or chronic, wounds. Thus,the number of chronic wounds is also increasing at a fast pace. READ MORE
