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

    Detta är en avhandling från Göteborg

    Författare :Lena Normén; Göteborgs universitet.; Gothenburg University.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

  2. 2. Studies of sterol 12alpha-hydroxylase (CYP8B1) : Distribution and role for cholesterol homeostasis and gallstone formation

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Laboratory Medicine

    Författare :Jin Wang; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP8B1; CY7P7A1; bile acid; cholesterol homeostasis; gallstone; nuclear receptor; cellular distribution; cholesterol hypersecretion; ABCG5 G8; SREBP2; cholesterol absorption; diabetes mellitus; anti-atherogenesis;

    Sammanfattning : Bile acids are essential physiological molecules which carry out multiple functions such as facilitating the absorption of dietary lipids and regulating the metabolism of cholesterol and bile acids. The formation of bile represents the major route for elimination of excess cholesterol, either by conversion of cholesterol into bile acids or excretion of intact cholesterol in mixed micelles.

  3. 3. Studies on the regulatory roles of cholesterol and bile acids

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Laboratory Medicine

    Författare :Charlotte Murphy; Karolinska Institutet.; Karolinska Institutet.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cholesterol; cholic acid; bile acids; cholesterol homeostasis; squalene epoxidase; mevalonate kinase; cob I alamin adenotransferase; SREBP; NF-Y;

    Sammanfattning : Cholesterol is essential for normal growth and development in mammals. However, excess cholesterol can be harmful leading to diseases such as atherosclerosis and gallstones. Once formed the ring structure of cholesterol cannot be catabolised by the body and must therefore be converted to other compounds for excretion. LÄS MER

  4. 4. Studies on the regulatory role of cholic acid in cholesterol metabolism

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Laboratory Medicine

    Författare :Charlotte Murphy; Karolinska Institutet.; Karolinska Institutet.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cholesterol is essential for normal growth and development in both man and mouse. However, excess cholesterol can be harmful leading to diseases such as atherosclerosis and gallstones. Once formed cholesterol cannot be catabolised by the body and must therefore be converted to other compounds for excretion. LÄS MER

  5. 5. Hygiene Aspects of Greywater and Greywater Reuse

    Detta är en avhandling från Stockholm : Mark och vatten

    Författare :Jakob Ottosson; KTH.; [2003]
    Nyckelord :greywater; greywater reuse; greywater treatment; microbial risk assessment; groundwater recharge; irrigation; recreational water; faecal contamination; indicator bacteria; index organisms; faecal sterols; bacteriophages; enteric pathogens; rotavirus; ;

    Sammanfattning : Greywater is domestic household wastewater without inputfrom the toilet, i.e. wastewater from sinks, the shower,washing machine and dishwasher in a home. Source separation ofgreywater can be a strategy to enhance recirculation of plantnutrients and/or improve water use. LÄS MER
