  1. 11. What contributes to human body burdens of phthalate esters? : An experimental approach

    Författare :Georgios Giovanoulis; Cynthia A. de Wit; Jörgen Magnér; Brice Appenzeller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phthalates; Alternative plasticizers; DINCH; In vivo screening; Urine; Nails; Air; Dust; Hand wipes; Duplicate diet; Predictors of exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Phthalate esters (PEs) and alternative plasticizers used as additives in numerous consumer products are continuously released into the environment leading to subsequent human exposure. The ubiquitous presence and potential adverse health effects (e.g. LÄS MER

  3. 12. Molecular genetic studies on cystinuria

    Författare :Lotta Harnevik; Peter Söderkvist; Catharina Larsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amino acid transport systems; Amino acids diamino; Mutation; Sulphydryl compounds; urine; Cystine; Carrier proteins; Cystinuria; DNA mutational analysis; Dog diseases; genetic; Membrane glycoproteins; Medical genetics; Medicinsk genetik;

    Sammanfattning : Cystinuria is defined as an inherited disorder characterized by increased urinary excretion of cystine and the dibasic amino acids arginine, lysine and ornithine. The only clinical manifestation of cystinuria is renal cystine stone formation due to the low solubility of cystine in the urine. LÄS MER

  4. 13. Analysis of Metabolites in Complex Biological Samples Using LC/MS and Multivariate Data Analysis : Metabolic Fingerprinting and Detection of Biomarkers

    Författare :Helena Idborg; Sven Jacobsson; Per-Olof Edlund; Jonas Bergquist; Stockholms universitet; []

    Sammanfattning : To facilitate early diagnosis of diseases and elucidation of the processes involved in their development and progression, various specific compounds or ‘biomarkers’ are often monitored. The first step is to decide which compounds to analyze. LÄS MER

  5. 14. Molecularly Imprinted Solid-Phase Extraction and Liquid Chromatography for Biological Samples

    Författare :Kristina Möller; Ulrika Nilsson; Maria Kempe; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi;

    Sammanfattning : This thesis focuses on the use of molecularly imprinted polymers as selective sorbents for solid-phase extraction (MISPE). The MISPE methods developed were mainly intended for use with biological samples, such as human urine and blood plasma. LÄS MER

  7. 15. Detection and Structure Elucidation of Drug Metabolites in Biological Samples using HPLC-MS/MS Techniques

    Författare :Annica Tevell Åberg; Mikael Hedeland; Ulf Bondesson; Mario Thevis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Sammanfattning : This thesis describes the structure elucidation of drug metabolites in biological samples by the use of high performance liquid chromatography (HPLC) atmospheric pressure ionization (API) tandem mass spectrometry (MS/MS). Due to their different advantages, various mass analyzers have been used in the different experiments. LÄS MER
