  1. 1. Dissecting sterol function during clathrin-dependent endocytosis and cytokinesis in Arabidopsis thaliana

    Författare :Márcia Frescatada-Rosa; Markus Grebe; Wolfgang Lukowitz; Umeå universitet; []
    Nyckelord :Arabidopsis; membrane; sterols; cytokinesis; KNOLLE; endocytosis; clathrin; DRP1A; Developmental Biology; miljömedicinsk utvecklingsbiologi; molekylärbiologi; Molecular Biology; molecular cell biology; molekylär cellbiologi;

    Sammanfattning : Sterols are lipid components of eukaryotic membranes. Alterations of membrane sterol composition perturb the execution of cell division, which in diverse eukaryotes can have severe consequences for development of the organism. Partitioning of the cytoplasm during cell division occurs at the final stage of cell division named cytokinesis. LÄS MER

  3. 2. Dietary intake of naturally occurring plant sterols in relation to serum cholesterol and myocardial infarction - Epidemiological studies from Sweden and the UK

    Författare :Sofia Klingberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; plant sterols; dietary intake; food sources; serum cholesterol; CVD; myocardial infarction; nutrition; epidemiology;

    Sammanfattning : Cardiovascular diseases (CVDs) are the leading cause of death in the world. High serum level of cholesterol is one of the major risk factors for CVD development. Serum levels of cholesterol can be modified by diet. LÄS MER

  4. 3. Mass spectrometry based analysis of endogenous sterols and hormones

    Författare :Neil de Kock; Jonas Bergquist; Kumari Ubhayasekera; William J. Griffiths; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mass spectrometry; supercritical fluid chromatography; UPSFC–MS MS; bioanalysis; steroids; oxysterols; thyroid hormones; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Sammanfattning : Bioanalytical applications using supercritical fluid chromatography (SFC) as analytical technique are of increasing interest. In essence, bioanalysis involves measurement of bioactive or endogenous compounds in biological matrices. LÄS MER

  5. 4. Phytosterols. Effect of intake on cholesterol absorption and colorectal cancer risk

    Författare :Lena Normén; Göteborgs universitet; []
    Nyckelord :phytosterols; phytostanols; soy sterols; sitostanol; ester; gas-liquid chromatography; GLC; cholesterol absorption; sterol excretion; fruit; vegetables; cereals; colon cancer; rectal cancer; dietary fiber;

    Sammanfattning : Phytosterols are lipid components of all food items of plant origin. They are effective in decreasing plasma cholesterol concentrations, but have also been suggested to protect against colorectal cancer. LÄS MER

  7. 5. Evaluation of microbial health risks associated with the reuse of source-separated humna urine

    Författare :Caroline Höglund; KTH; []
    Nyckelord :urine-separation; urine; wastewater systems; wastewater reuse; recycling; enteric pathogens; faecal sterols; indicator bacteria; hygiene risks; microbial persistence; microbial risk assessment; QMRA; fertiliser; crop;

    Sammanfattning : Human excreta contain plant nutrients and have the potentialto be used as a fertiliser in agriculture. Urine contributesthe major proportion of the nutrients (N, P and K) in domesticwastewater whereas faeces contribute a smaller amount andinvolves greater health risks if reused due to the possiblepresence of enteric pathogens.
