  2. 6. Physics of Viral Infectivity: Energetics of Genome Ejection

    Author : Meerim Jeembaeva; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microfluidics.; differential scanning calorimetry; capsid; Key words: phage; osmotic suppression; DNA ejection; isothermal titration calorimetry; enthalpy;

    Abstract : All viruses that infect bacteria, plant, or animal cells involve a genome (RNA or DNA) that is encapsidated by a rigid protein shell. After delivery of the viral genome into the host cell, new capsid proteins, which are encoded by viral DNA or RNA, are expressed and self-assembled into new viral capsids. READ MORE

  4. 7. Evaluation of the Tactoid Formation in Clay Systems

    Author : Maria Jansson; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lera; Montmorillonit; Nano-plattor; Taktoider; Anisotropi; Grov korninga modeller; MD simuleringar; MC simuleringar; SAXS; Svälltryck; Clay; Montmorillonite; Nanoplatelets; Tactoid; Anisotropy; Coarse-grained models; MD simulations; MC simulations; SAXS; Swelling pressure;

    Abstract : Clay minerals consist of anisotropic nanoplatelets where the majority of the clay minerals are highly charged, and thus, swell in aqueous solution. The structure and swelling depend on the type of clay mineral, and also on the ionic composition, and temperature. READ MORE

  5. 8. Structure and Function of the Borrelia burgdorferi Porins, P13 and P66

    Author : Mari Bonde; Sven Bergström; Melissa Caimano; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; P13; P66; porin; protein complex; dissemination; osmotic stress;

    Abstract : Borrelia burgdorferi is an elongated and helically shaped bacterium that is the causal agent of the tick-borne illness Lyme disease. The disease manifests with initial flu-like symptoms and, in many cases, the appearance of a skin rash called erythema migrans at the site of the tick bite. READ MORE

  6. 9. Characterization of the Mechanisms of Drug Release from Polymer-Coated Formulations using Experiments and Modelling

    Author : Mariagrazia Marucci; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ethyl cellulose; Release mechanism; coating; polymer blend; modelling; ESPI; diffusion; osmotic pumping; SEM; single pellet; CLSM; hydroxypropyl cellulose; multiple-unit release;

    Abstract : The main objectives of the work presented in this thesis were to develop new experimental methods to improve the understanding of the release mechanism from a coated formulation and to develop new mechanistic models to describe the release process for pellets coated with a semi-permeable film. Another aim was to characterize the release mechanism from a formulation coated with films made of a blend of a water-insoluble polymer, ethyl cellulose (EC), and a water-soluble polymer, hydroxypropyl cellulose (HPC).

  7. 10. Responding Model Membranes. Lipid Phase Behaviour, Domain Formation and Permeability

    Author : Emma Sparr; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water and solute flux; Gradients; Monolayer; Two-dimensional crystals; Line activiy; Osmotic stress; Interlamellar forces; Phospholipid-cholesterol interactions; Phase transitions; Bilayer stack; Stratum corneum; Physical chemistry; Fysikalisk kemi;

    Abstract : This thesis concerns the interplay between the lipid phase behaviour, domain formation and the permeability of bilayer membranes. An essential part of this work has been the understanding of the phase transitions and equilibrium properties of lipid bilayers. READ MORE
