    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; serologi; serology; Immunology; survival; proliferation; inhibition; NF-kB; Uncaria tomentosa; quinic acid;

    Sammanfattning : Extracts from the bark of the vine Uncaria tomentosa have anti-inflammatory, antiviral, antimutagenic and antioxidant effects. In this study, we evaluate the effects of an Uncaria tomentosa extract, denoted C-Med 100, on the cellular level of the immune system both in vivo and in vitro. LÄS MER

  5. 19. The metabolism of HIV RT inhibitors : biochemical and clinical studies

    Författare :Bengt Jacobsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : HIV infection is currently treated with a combination of nucleoside analogues and protease inhibitors. Nucleoside analogues inhibit HIV-1 reversed transcriptase (RT), a vital enzyme in the life cycle of HIV. Nucleoside analogues are phophorylated by host-cell enzymes to their respective triphosphate.
