  2. 6. Analysis of sterol metabolism in the pathogenic oomycetes Saprolegnia parasitica and Phytophthora infestans

    Author : Paul Dahlin; Vincent Bulone; Lisbeth Jonsson; Katharina Pawlowski; Lauren Mckee; Sophia Ekengren; Folke Sitbon; Steven Kelly; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant Physiology; växtfysiologi;

    Abstract : The primary objective of this thesis was to investigate the sterol metabolism of two pathogenic oomycetes, specifically the processes of sterol synthesis and sterol acquisition in the fish pathogen Saprolegnia parasitica (Saprolegniales) and the plant pathogen Phytophthora infestans (Peronosporales). Furthermore, the effects of steroidal glycoalkaloids from Solanaceous plants, on P. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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.

  6. 9. Characterisation of actin cytoskeletal functions and interactions during planar polarity formation in Arabidopsis

    Author : Christian Kiefer; Markus Grebe; Tijs Ketelaar; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The establishment of cell and tissue polarity is essential for the development of eukaryotic organisms including plants and animals. When cell polarity is uniformly organised within a plane of a single tissue layer, it is referred to as planar polarity. READ MORE

  7. 10. Regulation of sterol and glycoalkaloid biosynthesis in potato (Solanum tuberosum L.) : identification of key genes and enzymatic steps

    Author : Nurun Nahar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Steroidal glycoalkaloids (SGA) are toxic secondary metabolites present in some members of the Solanaceae family, including potato and tomato. The SGA level in tubers of potato (Solanum tuberosum L.) depends on genetic factors, but can also increase in response to e.g. READ MORE
