  2. 21. Supercritical Hydrogenation of Vegetable Oils

    Author : Maj-Britt Macher; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palladium catalyst; supercritical; hydrogenation; silver ion HPLC; rapeseed oil; fatty acid methyl ester; trans fatty acid; palm oil; deactivation; propane;

    Abstract : Vegetable oils were hydrogenated in a supercritical single-phase mixture with propane and hydrogen. The reaction was carried out in a small (0.5 ml) fixed-bed reactor and the influence of different process parameters was investigated. READ MORE

  4. 22. Exploring the Interplay of Lipids and Membrane Proteins

    Author : Candan Ariöz; Åke Wieslander; Daniel O. Daley; Malcolm East; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane lipids; membrane proteins; anionic lipids; membrane remodeling; intracellular vesicles; model membrane systems; glycosyltransferase; Escherichia coli; lipid composition; fatty acid modification; membrane curvature; bacterial homeoviscous adaptation; Biochemistry; biokemi;

    Abstract : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. READ MORE

  5. 23. Fatty acid transport proteins : candidate genes for the insulin resistance syndrome

    Author : Karl Gertow; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Fatty acid transport protein; fatty acid; triglyceride; lipoprotein; obesity; insulin resistance; adipose tissue; polymorphism; association study; gene expression;

    Abstract : The insulin resistance syndrome is characterised by insulin resistance, obesity, hypertension, and a typical dyslipidaemia, predisposing to diabetes and cardiovascular disease. Metabolic disturbances of the insulin resistance syndrome include dysregulation of fatty acid (FA) homeostasis, for which adipose tissue serves a critical function. READ MORE

  6. 24. When the paediatric heart is affected : impact on nutrition, growth and body composition from infancy to adolescence

    Author : Lena Hansson; Annika Rydberg; Inger Öhlund; Torbjörn Lind; Tanis Fenton; Umeå universitet; []
    Keywords : Congenital heart disease; Patent ductus arteriosus; Preterm infant; Infant growth; Energy intake; Dietary fatty acid; Micronutrient intake; Vitamin D; Dual-energy X-ray absorptiometry DXA ; Fontan circulation.; pediatrik; Pediatrics; Food and Nutrition; kostvetenskap; kardiologi; Cardiology;

    Abstract : BackgroundChildren with complex congenital heart disease (CHD) and very low birth weight (VLBW) infants with a patent ductus arteriosus (PDA) are two distinct groups of patients with different clinical care needs. Irrespective of the type of heart condition, nutritional intake and growth is largely affected in these individuals during infancy. READ MORE

  7. 25. Characterization of nucleic acid delivery with fatty acid modified cell-penetrating peptide nanoparticle formulations

    Author : Tõnis Lehto; Ülo Langel; Patrick Midoux; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transfection; gene delivery; oligonucleotide; complexes; non-viral; in vivo; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Recent advances with techniques used for manipulating gene expression have brought us to an era where various gene therapeutic approaches are becoming common therapeutic tools for many previously incurable diseases. The main factor impeding the wider translation of gene therapy is that the active pharmaceutical ingredients used for interfering with gene expression are based on nucleic acids and synthetic oligonucleotides and such molecules do not readily reach their intracellular targets due to their physicochemical properties and therefore they require delivery vectors to cross the cell membrane.
