  2. 1. [11C]Carbon Monoxide in Rhodium-/Palladium-Mediated Carbonylation Reactions

    Author : Julien Barletta; Bengt Långström; Yu-Shin Ding; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; carbonylation reaction; carbon monoxide; PET; 11C-labelling; rhodium; palladium; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : Methods for the 11C-labeling of carbonyl compounds applicable in the preparation of radiotracers for Positron Emission Tomography (PET) are described. To this end [11C]carbon monoxide at low concentration was used in transition metal- mediated reactions. READ MORE

  4. 2. Isocyanates and Amines – Sampling and Analytical Procedures

    Author : Åsa Marand; Gunnar Skarping; Marianne Dalene; Daniel Karlsson; Roy Rando; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Isocyanates; Amines; Polyurethane; Air sampling; Industrial hygiene; Mass spectrometry; Liquid chromatography; Chemiluminescence; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis covers sampling and analytical procedures for isocyanates (R-NCO) and amines (R-NH2), two kinds of chemicals frequently used in association with the polymeric material polyurethane (PUR). Exposure to isocyanates may result in respiratory disorders and dermal sensitisation, and they are one of the main causes of occupational asthma. READ MORE

  5. 3. Antigens derived from the mucin MUC1 : Solution and solid-phase synthesis of saccharides, peptides and glycopeptides

    Author : Maciej Pudelko; Mikael Elofsson; Fredrik Almqvist; Thisbe K. Lindhorst; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lactones; glycopeptides; signal peptide; neoglycolipid arrays; solid-phase synthesis; MUC1; gel-phase 19F NMR spectroscopy; fluorinated alpha-amino protective group; Organic chemistry; Organisk kemi;

    Abstract : Mucin is a term used to describe a large family of heavily glycosylated proteins which are present on the surfaces of secretory epithelial cells and are overexpressed by many carcinomas. Membrane-bound mucin MUC1 is of special interest. Its backbone consists of repeating units of twenty amino acids with five potential glycosylation sites. READ MORE
