  2. 11. Site-specific labeling of affinity molecules for in vitro and in vivo studies

    Author : Anna Perols; Amelie Eriksson Karlström; Christian Hackenberger; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Affibody molecules; molecular imaging; site-specific labeling; solid phase peptide synthesis; IgG-binding domains; photoconjugation.; Bioteknologi; Biotechnology;

    Abstract : The thesis is focused on site-specific labeling of affinity molecules for different applications where two types of binding proteins, Affibody molecules and antibodies, have been used. For the purpose of improving the properties of Affibody molecules for in vivo imaging, novel bi-functional chelators for radiolabeling using the radionuclide 111In were evaluated. READ MORE

  4. 12. Metabolism of inorganic arsenic and biomarkers of exposure

    Author : Gabriela Concha; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Arsenic; metabolism; methylation; biomarker; infant; children; women; drinking water; breast milk;

    Abstract : Humans as well as most mammals metabolize inorganic arsenic (Inorg As), a recognized human carcinogen, by methylation. The end-metabolites methylarsonic acid (MMA) and dimethylarsinic acid (DMA) are less toxic and more readily excreted in the urine than Inorg As. READ MORE

  5. 13. Synthesis and Characterization of Sec-Packings Based on Trimethylolpropane Trimethacrylate

    Author : Andrea Schmid; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bulk polymerization; N; hydrophilic gels; separation; methyl methacrylate; hydrophobic networks; acrylamide; porous networks; Suspension; N -methylene-bis-acrylamide; chemically crosslinked networks; dry gels; polysaccharide standards; distilled water; copolymerization; trimethylolpropane trimethacrylate;

    Abstract : Suspension and bulk polymerization of trimethylolpropane trimethacrylate (TRIM) and copolymerization of TRIM with methyl methacrylate (MMA) resulted in porous, hydrophobic, and chemically crosslinked networks. Copolymerization of TRIM with acrylamide (AA) and with N,N'-methylene-bis-acrylamide (bis-AA) resulted in hydrophilic gels. READ MORE

  6. 14. Lubrication mechanism of hydrocarbon-mimicking ionic liquids

    Author : Erik Nyberg; Ichiro Minami; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; P-SiSO; boundary film; silicate; friction; wear; anti-wear; friction modifier; base fluid; Maskinelement; Machine Elements;

    Abstract : Lubrication is critical in order to achieve high efficiency and reliability of machine elements such as gears, bearings, and other moving mechanical assemblies (MMA). In space applications, tribological properties of lubricants are quickly growing more important. READ MORE

  7. 15. Contact Allergy to Acrylates

    Author : Anthony Goon; Yrkes- och miljödermatologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; volatility; stability; screening; allergic contact dermatitis; Acrylates; baseline series; contact allergy; dental; gel permeation chromatography; high performance liquid chromatography; industrial; patch testing; methacrylates;

    Abstract : Acrylate contact allergy has been frequently reported since the 1970s, with hundreds of articles published in dermatology journals so far. The purpose of this thesis was to investigate the frequency of contact allergy to acrylates / methacrylates in patients with exposure to industrial, dental and nail uses of these substances. READ MORE
