  4. 28. The evolution of ribonucleotide reductases

    Författare :Daniel Lundin; Anthony Poole; Britt-Marie Sjöberg; Christos Ouzounis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; ribonucleotide reductase; horizontal gene transfer; phylogeny; protein classification; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : Ribonucleotide reductase (RNR) catalyses the transformation of RNA building blocks, ribonucleotides, to DNA building blocks, deoxyribonucleotides. This is the only extant reaction pathway for de novo synthesis of DNA building blocks and the enzyme is thus necessary for life. RNR is found in all but a few organisms. LÄS MER

  5. 29. Pain and radiographic changes of the arthritic temporomandibular joint : relation to cytokines in synovial fluid and plasma

    Sammanfattning : In patients with rheumatoid arthritis and other inflammatory joint diseases, radiographic changes of the TMJ are frequently observed. Common symptoms of TMJ involvement are pain at rest and on movement of the jaw. LÄS MER

  7. 30. Cognitive functioning in late senescence : influences of age and health

    Författare :Tarja-Brita Robins Wahlin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cognitive functioning; aging; health; individual differences;

    Sammanfattning : The overall aim of this doctoral thesis was to investigate potential age-related differences between groups of healthy very old adults from 75 to 96 years of age in various cognitive functions. An additional objective was to examine the influence of individual-difference variables within demographic (e.g., education, gender), psychometric (e. LÄS MER
