  1. 16. Analytical approaches to the study of mucin glycosylation

    Författare :Kristina A Thomsson; Göteborgs universitet; []
    Nyckelord :mucins; O-linked glycosylation; mass spectrometry; cystic fibrosis; salivary mucins; sulfated oligosaccharides.;

    Sammanfattning : Mucins constitute the major protein component of the mucus layer, which covers the epithelial surfaces of the respiratory, the gastrointestinal and the genitourinary tracts. Mucins carry O-linked oligosaccharides which contribute to the molecule by 50-80 weight percent, and these can be highly diverse, with 50-150 different oligosaccharides found on a purified mucin population.

  2. 17. New Techniques for Sample Preparation in Analytical Chemistry

    Författare :Zeki Altun; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Kemi; Chemistry;

    Sammanfattning : Sample preparation is often a bottleneck in systems for chemical analysis. The aim of this work was to investigate and develop new techniques to address some of the shortcomings of current sample preparation methods. LÄS MER

  3. 18. Determination of OPAHs and PAHs in Particulate Matter from Ambient Air and Engine Emissions : Multidimensional Chromatography

    Författare :Trifa Mohammad Ahmed; Roger Westerholm; Peter Haglund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Particulate matter (PM) is an air pollutant that seriously impacts human health. Epidemiological studies have shown associations between human exposure to urban air PM and lung cancer, respiratory and cardiovascular diseases. LÄS MER

  4. 19. Metabolomics and wood development : catching a metabolome

    Författare :Annika Johansson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The tree industry is one of Sweden's most important economic sectors, producing pulp, paper, wooden goods and wood as a bioenergy source. Understanding the biology behind the processes of tree growth and wood development is a key to maximizing the use of wood as raw material. LÄS MER
