  1. 16. New Materials and Improved Ambient Techniques in Mass Spectrometry

    Författare :Nicolò Riboni; Leopold Ilag; Elisa Robotti; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass Spectrometry; Solid Phase Microextraction; Ambient Mass Spectrometry; Desorption Electrospray Ionization; Paper Spray Ionization; Cavitands; BTEX; New Psychoactive Substances; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Mass spectrometry (MS) is used in several fields, e.g. biology, environmental monitoring, medicine and forensics due to excellent qualitative and quantitative capabilities. The development of new instrumental setups and ionization sources is crucial to analyze a variety of compounds at trace levels. LÄS MER

  3. 17. Analytical Methods For Sports Drugs: Challenges and Approaches

    Författare :Hatem Elmongy; Magnus Ericsson; Leopold Ilag; Mikael Hedeland; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sports Drugs; Doping in Sports; Steroids; LC-MS MS; Chiral analysis; high-resolution mass spectrometry; Sample preparation; Biological samples; solid phase extraction; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Drugs used to enhance human performance in sport competitions are prohibited by the world anti-doping association (WADA). Biological samples from athletes are continuously tested for adverse analytical findings regarding the identity and/or quantity of the banned substances. LÄS MER

  4. 18. Occurrence and removal of organic micropollutants in drinking water : Analytical approaches for wide-scope screening of contaminants of emerging concern

    Författare :Rikard Tröger; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : With the rapidly expanding global population, demand for clean drinking water is increasing. However, the widespread use of synthetic chemicals makes it challenging to produce safe and clean drinking water. LÄS MER

  5. 19. Secondary metabolites from the saprotrophic fungus Granulobasidium vellereum

    Författare :Christina Nord; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The production of secondary metabolites by the saprotrophic fungus Granulobasidium vellereum was investigated. G. vellereum is a wood decomposing basidiomycete fungus that arrives at dead trunks of fallen hard wood trees at a later stage of the decomposition process and hence need to outcompete the organisms already colonizing the site.

  7. 20. The activation and regulation of plasmacytoid dendritic cells in SLE : and possible therapeutic interventions

    Författare :Karin Hjorton; Lars Rönnblom; Maija-Leena Eloranta; Hans Carlsten; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SLE; pDCs; NK cells; interferon; autoantibodies; immune complex; hydroxychloroquine; IRAK4 inhibition;

    Sammanfattning : Systemic Lupus Erythematosus (SLE) is an autoimmune disease, characterized by the presence of anti-nuclear antibodies and the formation of nucleic acid containing immune complexes (ICs), which can cause organ damage by deposition in tissues. ICs strongly trigger the plasmacytoid dendritic cells (pDCs) to produce interferon (IFN)-α, which potently activates the immune system. LÄS MER
