    Sammanfattning : .... LÄS MER

  3. 2. The large sialoglycoprotein of human lymphocytes

    Författare :Bernt Axelsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : L-LSGP is an abundant cell surface glycoprotein (a.m.w. intact 115—125 kdalton, desialylated 140—160 kdalton) restricted to lymphocytes in the hemopoietic system. LÄS MER

  4. 3. Radiation-induced apoptosis in human lymphocytes : studies on expression, function and effects of different radiation qualities

    Författare :Annelie Meijer; Fabrizio Palitti; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Apoptosis; clonogenic survival; growth factors; chromosomal aberrations CA ; low dose-rate LDR ; linear energy transfer LET ; relative biological effectiveness RBE ; radio sensitivity; ataxia telangiectasia A-T ; Physical Biology; fysikalisk biologi;

    Sammanfattning : We are constantly exposed to radiation. Radiation causes damage to our cells. By the removal of damaged and unwanted cells, apoptosis is considered to be one of the most indispensable defence processes for a multi-cellular organism. LÄS MER

  5. 4. Chemically Induced DNA Damage in Extended-term Cultures of Human Lymphocytes

    Författare :Maria Andersson; Björn Hellman; Leif Busk; Uppsala universitet; []
    Nyckelord :Toxicology; Comet assay; DNA-damaging agents; DNA repair; Extended-term Cultures of Human Lymphocytes; Genotoxicity; Induced DNA damage; In vitro; Mouse Lymphoma Cells; Primary Cell Cultures; Reactive Oxygen Species; Toxikologi;

    Sammanfattning : Generation of DNA damage is regarded to be an important initial event in the development cancer. Consequently, a battery of tests have been developed to detect different types of genotoxic effects in order to be able to predict the potential genotoxicity and mutagenicity of chemicals, including both pharmaceutical drugs and various types of environmental and occupational agents, as well as dietary factors.

  7. 5. Biosynthesis and biological role of leukotrienes in human lymphocytes

    Författare :Yilmaz Mahshid; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Leukotrienes (LT) are biologically active metabolites of arachidonic acid. The key enzyme in leukotriene biosynthesis is 5-lipoxygenase (5-LO). Leukotriene B4 exerts its biological effect mainly via BLT1, the high affinity receptor for LTB4. Leukotriene B4 is a potent proinflammatory and chemotactic mediator. LÄS MER
