  2. 21. Structure and function of the HDL receptor SR-BI : scavenger receptor class B type I

    Author : Magnus S.C. Johnson; Göteborgs universitet; []
    Keywords : SR-BI; HDL; Cholesterol; Scavenger receptor; Apoptosis; Ovary; Gallbladder; Peroxisome;

    Abstract : Low plasma levels of high-density lipoprotein (HDL) and high levels of low-density lipoprotein (LDL) are well-recognized risk factors for cardiovascular disease. The uptake and degradation of LDL cholesterol have been characterized in detail at the molecular level. Less is known about the metabolism and cellular uptake of HDL cholesterol. READ MORE

  4. 22. Self-Assembly in Lipid-Protein Systems : Lung Surfactant, Stratum Corneum and Model Membranes

    Author : Jenny Andersson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lipid self-assembly; lung surfactant; stratum corneum; dehydrin; cholesterol; osmolytes; urea; TMAO; ssNMR; cSAXS;

    Abstract : This thesis explores lipid self-assembly and aims to give a broad picture of self-assembly structures in simple and complex lipid-protein systems. The systems studied are lung surfactant, stratum corneum and simple model membranes. The lung surfactant mixture lines the alveolus in our lungs and stabilises the air- tissue interface. READ MORE

  5. 23. Risk factors for fractures - a link between metabolic bone disease and cardiovascular disease

    Author : Penelope Trimpou; Göteborgs universitet; []
    Keywords : Risk factors; General population; Physical activity; Sex hormones; Cholesterol; Stroke; Fracture;

    Abstract : Introduction: Fractures and cardiovascular disease (CVD) are a burden to society, as they result in high morbidity and mortality in both men and women. Aim: The aim was to study prospectively modifiable risk factors for fractures in the general population and to possibly identify a link between metabolic bone disease and CVD. READ MORE

  6. 24. A Surface Phase Model of the Alveolar Lining: Ultrastructural Analysis and in vivo Applications

    Author : Marcus Larsson; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; X-ray diffraction; cryo-TEM; dynamic swelling; ARDS; surface phase; surfactant replacement therapy; cholesterol; minimal surface; pulmonary surfactant; alveolar surface; Physiology; Fysiologi;

    Abstract : In this thesis the relation between lung surfactant structure and functional properties have been studied. Experimental results show that the alveolar surface is formed by a coherent surface phase with a structure equal to tubular myelin. The properties of this phase may explain certain unresolved issues in lung physiology, e.g. READ MORE

  7. 25. Methods for elucidating membrane protein structure and function

    Author : Carolina Trkulja; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; patch clamp; antibodies; mass spectrometry; ion channels; proteomics; fluorescence; TRPV1; cholesterol.; limited proteolysis; Membrane proteins;

    Abstract : Elucidation of the structure-function relationship of membrane proteins increases our understanding of many biological processes, both physiological and pathological. However, membrane proteins have been notoriously difficult to study, having part of their structure embedded into the lipid cell membrane. READ MORE
