  2. 1. Computer Simulations of Membrane–Sugar Interactions

    Author : Jon Kapla; Arnold Maliniak; Alexander Lyubartsev; Ilpo Vattulainen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular simulations; Molecular dynamics; Lipid bilayers; Carbohydrates; Biological membranes; Trehalose; Glycolipids; Membrane—sugar interactions; fysikalisk kemi; Physical Chemistry;

    Abstract : Carbohydrate molecules are essential parts of living cells. They are used as energy storage and signal substances, and they can be found incorporated in the cell membranes as attachments to glycoproteins and glycolipids, but also as free molecules. READ MORE

  4. 2. Composition-Structure Correlations of Bioactive Glasses Explored by Multinuclear Solid-state NMR Spectroscopy

    Author : Renny Mathew; Mattias Edén; Robert Hill; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioactive glasses; glass structure; orthophosphate distribution; solid-state NMR; dipolar interactions; dipolar recoupling; multiple-quantum spin counting; READOR; REAPDOR; fysikalisk kemi; Physical Chemistry;

    Abstract : This PhD thesis presents a study of structure-composition correlations of bioactive glasses (BGs) by employing solid-state Nuclear Magnetic Resonance (NMR) spectroscopy.Silicate-based Na2O−CaO−SiO2−P2O5 BGs are utilized clinically and are extensively investigated for bone regeneration purposes.

  5. 3. Solitons, vortices and shell structure in ultracold atomic quantum systems

    Author : Gunnar Eriksson; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; few-body physics; finite-size effects; solitary waves; quantized vortices; quantum hysteresis; shell structure; dipolar interactions; Fysicumarkivet A:2020:Eriksson;

    Abstract : This dissertation deals with finite-size effects in a few different quantum many-body phenomena in ultracold atomic systems. The finite-sized systems were simulated numerically using both mean-field methods and methods beyond mean-field, e.g. quadratic configuration interaction and exact diagonalization. READ MORE

  6. 4. Anisotropic Protein Interactions in Salt Solutions and at Interfaces: Coarse Grained Modeling

    Author : Anil Kurut Sabanoglu; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anisotropic interactions; protein electrostatics; phase association; surface adsorption; coarse grained models; Monte Carlo simulations;

    Abstract : Anisotropic protein interactions have a strong orientation dependence resulting from an uneven distribution of charged and hydrophobic residues on the protein surface. They play an important role in protein behaviors such as protein association, surface adsorption and phase separation. READ MORE

  7. 5. Molecular basis for galectin-ligand interactions : Design, synthesis and analysis of ligands

    Author : Kristoffer Peterson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galectin; Structure-based design; Thiodigalactoside; Huisgen 1; 3-dipolar cycloaddition; Protein-ligand binding interactions;

    Abstract : Galectins are a class of β-galactoside-binding proteins that bind glycoconjugates and have been implicated in cancer, regulation of immunity and inflammation. Design and synthesis have achieved highly potent and selective galectin ligands that can inhibit interactions with glycoproteins and have consequent cellular effects. READ MORE
