  1. 1. Telomerase activation and its clinical implications in human thyroid tumors

    Författare :Na Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Telomerase is a ribonucleoprotein enzyme. The catalytic and rate-limiting component of telomerase is referred to as telomerase reverse transcriptase (TERT) that plays an important role in telomere maintenance, cell immortalization and malignant transformation. LÄS MER

  3. 2. Differential maturation of Na+,K+-ATPase in the rat : transcriptional regulation by glucocorticoids

    Författare :Zheng-Ming Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :glucocorticoids; ontogeny; Na ; K -ATPase; H ; K -ATPase; iontransporter; kidney; lung; heart; stomach; colon.;

    Sammanfattning : Na+,K+-ATPase is a ubiquitous transmembrane enzyme that creates the electrochemical gradient across the cell membrane. Na+,K+-ATPase activity is low in many immature tissues. LÄS MER

  4. 3. Influenza Neuraminidase : Novel mechanisms of influenza NA that enable adaptation and promote diversification

    Författare :Hao Wang; Robert Daniels; Colin Russell; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Influenza; IAV; neuraminidase; transmembrane domain; the central Ca2 binding site; heterotetrameric formation; viral incorporation; evolution; adaptation; diversification; Biochemistry; biokemi;

    Sammanfattning : Influenza A viruses (IAVs) are one of the most common human respiratory pathogens and are largely responsible for the seasonal influenza epidemics that cause mild to severe disease. The two IAV glycoproteins, hemagglutinin (HA or H) and neuraminidase (NA or N), serve as the major surface antigens and also are the main determinants of infectivity, pathogenicity and transmissibility.

  5. 4. Theoretical studies of thermodynamic properties of condensed matter under high temperature and high pressure

    Författare :Yi Wang; KTH; []
    Nyckelord :;

    Sammanfattning : Based on first-principles calculations coupled with theclassical mean-field potential approach. A wide range ofthermodynamic properties have been studied. This includesambient condition properties, 300-K equation of state,shock-wave Hugoniot, reduction of shock-wave data, highpressure melting, anharmonic e.ects and etc. LÄS MER
