  1. 1. Statistical Physics of DNA: Melting and Confinement Effects

    Författare :Michaela Reiter-Schad; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biopolymers; DNA melting; DNA confinement; random walk; Fysicumarkivet A:2015:Reiter-Scad;

    Sammanfattning : Investigation of single macromolecules makes it possible to gain insight into and characterize important biological processes. DNA as the molecule of life is of special interest here. LÄS MER

  3. 2. Transport Modes in Nanotube-Vesicle Networks

    Författare :Michal Tokarz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; confinement; liposome; biomimetic; micromanipulation; Vesicle; electrophoresis; network; nanotube; transport;

    Sammanfattning : Methods for construction of surface-immobilized microscopic networks of phospholipid bilayer vesicles (3-50 µm in diameter) interconnected by lipid tubes (30-150 nm in radius), have previously been developed. The networks have controlled connectivity and are well-defined with regard to container size, content, angle between nanotube extensions, and nanotube length. LÄS MER

  4. 3. Repression of transcription factor NF-[kappa]B by glucocorticoids : a molecular mechanism for their anti-inflammatory and immuno-modulatory effects

    Författare :Johan Lidén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : It has been known since the late 1940s that glucocorticoids (GCs) possess anti-inflammatory activity. Their various uses in the clinic include treatment of, rheumatoid arthritis, asthma and AIM skin diseases and also as means for avoiding rejection during transplantation. LÄS MER

  5. 4. A Quantum Chemical View of Molecular and Nano-Electronics

    Författare :Jun Jiang; Yi Luo; Jim Greer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi;

    Sammanfattning : This dissertation presents a generalized quantum chemical approach for electron transport in molecular electronic devices based on Green's function scattering theory. It allows to describe both elastic and inelastic electron transport processes at first principles levels of theory, and to treat devices with metal electrodes either chemically or physically bonded to the molecules on equal footing.

  7. 5. The genetic composition and diversity of Francisella tularensis

    Författare :Pär Larsson; Anders Sjöstedt; Andrew K. Benson; Umeå universitet; []
    Nyckelord :Microbiology; tularemia; genotyping; evolution; microarray; genome sequencing; virulence; genome reduction; Mikrobiologi; Francisella tularensis; klinisk bakteriologi; Clinical Bacteriology;

    Sammanfattning : Francisella tularensis is the causative agent of the debilitating, sometimes fatal zoonotic disease tularemia. To date, little information has been available on the genetic makeup of this pathogen, its evolution, and the genetic differences which characterize subspecific lineages. These are the main areas addressed in this thesis. LÄS MER
