  1. 21. Fiber-optic communications with microresonator frequency combs

    Författare :Attila Fülöp; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Modern data communication links target ever-higher information throughput. To utilize the available bandwidth in a single strand of fiber, optical communication links often require a large number of lasers, each operating at a different wavelength. LÄS MER

  3. 22. DNA fragmentation in cultured cells exposed to high linear energy transfer radiation

    Författare :Erik Höglund; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi; Oncology; Onkologi; Biomedical Radiation Science; biomedicinsk strålningsvetenskap;

    Sammanfattning : The DNA double-strand break (DSB) is a critical lesion which, if not completely restored, can have serious biological consequences. The relative biological effectiveness (RBE) of many severe end-points are closely related to radiation quality, with increased effectiveness at elevated ionization density. LÄS MER

  4. 23. Characterization of dengue virus isolates from patients experiencing dengue fever, dengue hemorrhagic fever, and dengue shock syndrome

    Författare :Anne Tuiskunen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The four serotypes of dengue virus (DENV) belong to the genus flavivirus, and have a positive sense, single-stranded RNA genome of ~11 kb. The DENVs cause the most common arthropod-borne viral disease in man with ~100 million infections per year. The sole measure of control is limiting the mosquito vectors Aedes aegypti and Ae. LÄS MER

  5. 24. Development of novel DNA vaccine and immunotherapeutic approaches

    Författare :Maroof Hasan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Many potential DNA vaccination and immunotherapeutic strategies has been explored in both animal models and human settings in recent years. However, the failure of efficient and safe method development suggests that it is time to rethink, since more innovative approaches are needed for better control of infection and immunotherapy.

  7. 25. The role of chromatin in the induction and repair of DNA damage

    Författare :Mats Ljungman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA damage; Chromatin; Kromatin; DNA;

    Sammanfattning : The role of chromatin in the induction and repair of DNA damage has a dual nature.The constituent proteins of chromatin protect the DNA against the induction of DNAdamage, while at the same time they reduce the accessibility of DNA to repair enzymes. LÄS MER
