  2. 1. Association and Microstructure in Self-Assembling Catanionic Systems

    Author : Eduardo Marques; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFG NMR self-diffusion; cryogenic-transmission electron microscopy; catanionic systems; gels; bile salts; polyelectrolytes; liquid crystals; vesicles; Surfactants; phase diagrams; light microscopy; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

    Abstract : This thesis addresses the phase behavior and phase structure in mixed surfactant-surfactant and surfactant-polymer systems, where the co-solutes have opposite charges (catanionic systems). The initial goal has been to investigate self-assembly aspects in mixtures of single-/double-chained surfactants and bile salt/double-chained surfactants, with the main focus on vesicle assembly in dilute regions.

  4. 2. Versatile Association Behavior in Mixtures of Oppositely Charged Amphiphiles : From DNA-Like Assembly of Supramolecular Helices to Coacervation in Chiral Surfactant Systems

    Author : Guanqun Du; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bile salts; Block copolymers; Oppositely charged polymer-surfactant systems; Co-assembly; BS sequestrants; Gemini surfactants; Supramolecular helices; Hexagonal packing; Chirality; Thermoresponsive behavior; Scattering; Tomography; Calorimetry;

    Abstract : As biological surfactants, bile salts (BSs), play important roles in biological processes, i.e., food digestion, but also in BS-related diseases, as well as in applications. READ MORE

  5. 3. Hydrophobic interactions of serpins

    Author : Sabina Janciauskiene; Enheten för kroniska inflammatoriska och degenerativa sjukdomar; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Proteiner; enzymology; polymerization.; Proteins; conformational polymorphism; hydrophobic interaction; amyloid fibrils; Alzheimer`s peptide Ab; alpha-1-antichymotrypsin; C-terminal peptide; lithocholic acid; cholesterol; Key words: alpha-1-antitrypsin; bile acids; enzymologi;

    Abstract : The proteins of the serpin family are primarily but not exclusively proteinase inhibitors, which share a common, similar structure. It is known that this structure undergoes major conformational changes upon cleavage in the serpin reactive site loop, and that these changes include rearrangements within the hydrophobic core of the molecule.

  6. 4. Studies on the Expression and Regulation of Enterotoxins and Colonization Factors in Enterotoxigenic Escherichia coli (ETEC)

    Author : Matilda Nicklasson; Göteborgs universitet; []
    Keywords : ETEC; heat-stable enterotoxin; heat-labile enterotoxin; colonization factors; CS5; CS6; virulence gene expression; in vivo and in vitro; genetic variability;

    Abstract : Enterotoxigenic Escherichia coli (ETEC) is one of the most common causes of acute watery diarrhoea in developing countries, particularly among local children less than five years and is also the most common cause of diarrhoea in travellers to ETEC endemic areas. The infection is transmitted by ingestion of contaminated food and water and the disease is established in the small intestine. READ MORE

  7. 5. Water-swelling tablets based on hydrophobically modified poly(acrylic acid) - Effects of amphiphiles on swelling and drug release

    Author : Patrik Knöös; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drug deliver; Controlled release; Hydrophobically modified polymers; Surfactant-polymer interactions; Poorly soluble drug;

    Abstract : An important issue within the pharmaceutical world today is the increasing number of poorly soluble drugs. These often show a low bioavailability and a susceptibility to varying conditions in the intestine. READ MORE
