  2. 1. Drug Partitioning into Natural and Artificial Membranes : Data Applicable in Predictions of Drug Absorption

    Author : Caroline Engvall; Birgitta Tomkinson; Katarina Edwards; Sven Engström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Bilayer disk; Cholesterol; Drug partitioning; Drugs; Electrostatic effects; Immobilized liposome chromatography; Liposome; Membrane protein; Model membrane; Oligonucleotide-liposome complex; Phospholipid; Phospholipid bilayer; Proteoliposome; Surfactant; Biokemi; Biochemistry; Biokemi;

    Abstract : When drug molecules are passively absorbed through the cell membrane in the small intestine, the first key step is partitioning of the drug into the membrane. Partition data can therefore be used to predict drug absorption. READ MORE

  4. 2. Protein-surfactant interactions

    Author : Ank Valstar; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Abstract : Protein-surfactant interactions in aqueous media have been investigated. The globular proteins lysozyme and bovine serum albumin (BSA) served as model proteins. Several ionic and non-ionic surfactants were used.Fluorescence probe measurements showed that at low sodium dodecyl sulfate (SDS) concentration (< 0. READ MORE

  6. 4. Association and Interactions in Protein-Surfactant Systems

    Author : Anna Stenstam; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catanionic surfactant; SANS; NMR; gel; sodium alkylsulfate; Protein-surfactant interactions; lysozyme; LH2; Physical chemistry; Fysikalisk kemi;

    Abstract : Aggregation in protein-surfactant systems have been studied with the ambition of reaching a deeper understanding of the balance of the interaction forces involved. A pure system with maximized electrostatic interactions has been used. READ MORE

  7. 5. Wetting and Capillary Flow of Surfactant Solutions and Inks

    Author : Maria von Bahr; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; AKD; ink-jet printing; paper; penetration; absorption; adsorption; hydrophobicity; nonionic; surfactant; spreading; dynamic wetting;

    Abstract : This thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. READ MORE
