    Sammanfattning : We prove equidistribution results for (pieces of) closed horospheres in cofinite hyperbolic manifolds of dimension n+1, using spectral methods. This extends earlier results by Hejhal [Hej2] and Str¨ombergsson [St1] in dimension 2... LÄS MER

  4. 4. Atherosclerotic cardiovascular disease in rheumatoid arthritis aspects of pathogenesis and risk

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Bengt Wahlin; Solveig Wållberg-Jonsson; Anna Södergren; Anders Bengtsson; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; inflammation; atherosclerosis; cardiovascular disease; risk estimation; cytomegalovirus; T-cells; bone turnover; osteoprotegerin; osteocalcin; Medicine; medicin;

    Sammanfattning : Patients with rheumatoid arthritis (RA) have an increased prevalence and severity of atherosclerosis, and a corresponding increased risk of cardiovascular disease. The mechanisms causing this are not well elucidated, but both traditional cardiovascular risk factors and RA-associated factors have been associated with atherosclerosis and increased risk of cardiovascular events in patients with RA.
