  1. 16. Studies on the remineralization of white spot lesions : longitudinal assessment with quantitative light-induced fluorescence

    Författare :Susan Al-Khateeb; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The global aim of this work was to develop and test the light induced fluorescence method using either laser light or a regular, i.e. noncoherent light source for quantification of mineral changes in white spot lesions. Validation studies were carried out to establish the correlation between fluorescence loss and mineral loss. LÄS MER

  5. 19. Light induced destruction of indole-3-acetic and some physiological effects on one of its metabolites, 3-methyleneoxindole

    Författare :Punam Bhatnagar; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Studies conducted on Lemma gibba in sterile nutrition medium with labelled indole-3-acetic acid (IAA-1- 14C), confirmed that IAA is highly photosensitive in aqueous solutions. About 80 % of the IAA was decarboxylated within 24 h of exposure to fluorescent light. LÄS MER

  7. 20. Formation and metabolism of the tryptophan-derived 6-formylindolo[3,2-b]carbazole - a light-induced Ah-receptor ligand

    Författare :Linda Bergander; Ulf Rannug; Agneta Rannug; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Toxikologi;

    Sammanfattning : The aryl hydrocarbon receptor (AhR) is a ligand dependent transcription factor ubiquitously expressed in mammalian cells. It is a genetically ancient protein mostly known for binding the extremely toxic contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). LÄS MER
