  1. 36. Structural transitions of proton-gated ion channels : Involving pH sensing, heterogeneity and lipid interactions

    Författare :Urška Rovšnik; Erik Lindahl; Hugues Nury; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ion channels; cryo-electron microscopy; pH gating; simulations; structure-function relationship; GLIC; DeCLIC; biokemi; Biochemistry;

    Sammanfattning : Studying protein structure and function involves analyzing the relationship between a protein's three-dimensional assembly and its dynamic biochemical activity. The superfamily of pentameric ligand-gated ion channels (pLGICs) constitutes a classic yet illuminating experimental system for structure-function studies. LÄS MER

  3. 37. Le corps de l'enfant

    Författare :Nathalie Tresch; France Robert Schuman University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Rättsvetenskap; Law;

    Sammanfattning : The thesis is divided in two main parts. On one hand the protection of the child's body, on the other its utilization. One tries to verify to what extent the protection and the utilization can be compatible and to criticize the situations where utilization takes over protection. LÄS MER

  4. 38. Sharing the doughnut : Exploring sustainable and just futures

    Författare :Eléonore Fauré; Ulrika Gunnarsson-Östling; Göran Finnveden; Frances Fahy; KTH; []

    Sammanfattning : Despite decades of international discussions or summits on the need to radically reduce e.g. increasing concentrations of greenhouse gases (GHGs) or biodiversity loss, these are still rising. LÄS MER

  5. 39. Conséquences d’un stress chronique sur la barrière de mucus intestinal chez le rat : effet du probiotique Lactobacillus farciminis

    Författare :Stéphanie da Silva; Muriel Mercier-Bonin; Annick Bernadier-Donadille; Bruno Pot; Nathalie Juge; France Clermont Ferrand University UMR454 INRA; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background. Despite a large body of literature incriminating mucus alterations in the pathogenesis of Intestinal Bowel Diseases (IBD), structural and physical changes in the mucus layer remain poorly understood in the micro-inflammatory context of Irritable Bowel Syndrome (IBS).

  7. 40. Poly(Ethylene Oxide) Based Bottle-Brush Polymers and their Interaction with the Anionic Surfactant Sodium Dodecyl Sulphate : Solution and Interfacial Properties

    Författare :Joseph Iruthayaraj; Per M. Claesson; Regine v. Klitzing; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEO brush polymers; brush polymers; PEO; poly ethylene oxide ; polymer-surfactant; sodium dodecyl sulphate SDS ; Ellipsomtery; PEO-SDS interactions; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The aim of this thesis work is to study the physico-chemical properties of poly(ethylene oxide), PEO, based brush polymers both in solution and at solid/aqueous interfaces. The importance of studying the surface properties of brush polymers can be related to a broad spectrum of interfacial-related applications such as colloidal stability, lubrication, detergency, protein repellency to name a few.
