    Sammanfattning : Inflammatory bowel disease (IBD) is a group of chronically relapsing immune-related disorders, engaging the gastrointestinal tract. Symptoms vary depending on inflammatory phenotype, but may include diarrhoea, bowel pain and weight loss. The two most common entities are Crohn's disease and ulcerative colitis (UC). LÄS MER

  3. 2. Meteoric Aerosols in the Middle Atmosphere

    Författare :Linda Megner; Jörg Gumbel; Martin Ridal; Gary E. Thomas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; meteoroid; meteor; nucleation; mesosphere; stratosphere; ablation; smoke; NLC; PMSE; PSC; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : This thesis concerns the fate of the meteoric smoke in the Middle Atmosphere, and its effect on ice phenomena such as noctilucent clouds (NLC) and polar stratospheric clouds (PSC). The potential role of NLC as tracer for mesospheric processes and variability, and as a tool for monitoring this remote and inaccessible region, has generated substantial interest within the scientific community.

  4. 3. Biliary epithelial cells, the immune system and PSC pathogenesis

    Författare :Lena Berglin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Primary sclerosing cholangitis (PSC) is a chronic, inflammatory liver disease that leads to destruction of the bile duct system. PSC is strongly associated with inflammatory bowel disease, and PSC patients have an increased risk of developing malignancies, especially cholangiocarcinoma (CCA). LÄS MER

  5. 4. Magnetic resonance imaging as a tool for diagnosis, evaluation, and prognosis in patients with primary sclerosing cholangitis

    Författare :Aristeidis Grigoriadis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Primary sclerosing cholangitis (PSC) is a chronic liver and bile duct disease of unknown etiology. It usually progresses to liver failure and need for liver transplantation. Additionally, patients with PSC have an increased risk of developing hepatobiliary malignancies, predominantly cholangiocarcinoma. LÄS MER

  7. 5. Biliary strictures in primary sclerosing cholangitis : aspects on inflammation and malignancy

    Författare :Erik von Seth; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Primary sclerosing cholangitis (PSC) is a rare liver disease that is characterized by chronic inflammation of bile ducts with development of fibrosis and strictures. The pathogenic mechanisms involved in this disease are insufficiently understood. LÄS MER
