  1. 1. Attractive Patchy Protein Interactions : Understanding of protein dimerization

    Författare :Weimin Li; Fysikalisk kemi; []
    Nyckelord :Patchy Attractions; Protein Interactions;

    Sammanfattning : Protein interactions are important in understanding various protein relevant cellular and technological processes.This is a challenging task due to the intrinsically irregular shape and inhomogeneous surface distribution of neutral, charged, hydrophobic amino acid residues.

  3. 2. Fluids, Gels and Crystals : Phase behavior of binary thermoresponsive microgel mixtures

    Författare :Jasper Immink; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colloidal phase behavior; microgel; binary mixture; colloidal gel; sequential gelation; patchy particle; binary crystal; crystal-to-crystal transition;

    Sammanfattning : Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction.

  4. 3. On transplantation of fetal ventral mesencephalon with focus on dopaminergic nerve fiber formation

    Författare :Nina Törnqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :VM; graft; Parkinson s disease; graft reinnervation; striatum; patchy; intraocular transplantation; intracranial transplantation; primary culture;

    Sammanfattning : Poor cell survival and striatal reinnervation are two of the postulated limiting factors of fetal ventral mesencephalic (VM) grafting in Parkinson's disease. It has, however, been reported that an increased survival of VM dopaminergic neurons does not correlate with an enhanced target innervation. LÄS MER

  5. 4. Modelling anisotropic interactions in colloidal systems

    Författare :Alexei Abrikossov; Fysikalisk kemi; []
    Nyckelord :SIMULATION; Modelling; electrostatic interactions; Colloids; Statistical mechanics; SIMULATION; Modelling; electrostatic interactions; colloid; Statistical mechanics;

    Sammanfattning : There has been an increased interest to design “smart materials” which can self-assemble into complex structures in accordance to external factors such as for example electromagnetic fields. By designing particles with directional interactions one is able to control how particles will interact with each other. LÄS MER

  7. 5. Intracranial and intraocular grafting of fetal ventral mesencephalic and striatal tissues : neuronal survival and nerve growth characteristics

    Författare :Lars Björklund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Parkinson s disease; grafting; ventral mesencephalon; striatum; dopamine; innervation; growth pattem; GDNF; U-74006F;

    Sammanfattning : Parkinson's disease is caused by degeneration of dopaminergic neurons in the ventral mesencephalon. Various animal models and clinical trials has shown that grafts of fetal ventral mesencephalic tissue can survive and functionally reinnervate the dopamine-depleted striatum, leading to long-term improvements of therapeutic value, but still symptomatic relief is far from complete.
