  1. 6. Ionization and Fragmentation of Complex Molecules and Clusters : Biomolecules and Polycyclic Aromatic Hydrocarbons

    Författare :Henrik A. B. Johansson; Henning Schmidt; Henrik Cederquist; Henning Zettergren; Thomas Schlathölter; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Sammanfattning : This work deals with ionization and fragmentation of biomolecules and polycyclic aromatic hydrocarbon (PAH) molecules. They are studied in the gas phase both as isolated molecules and as weakly bound clusters. LÄS MER

  3. 7. Epidemiology of venous thromboembolism with focus on risk markers

    Författare :Magdalena Johansson; Lars Johansson; Marcus Lind; Jan-Håkan Jansson; Gerd Lärfars; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Venous thromboembolism; venous thrombosis; deep vein thrombosis; pulmonary embolism; incidence; risk markers; diabetes; glucose; alcohol consumption; alcohol dependence; physical activity; medicin; Medicine;

    Sammanfattning : Background: Venous thromboembolism (VTE) is a vascular disease with an incidence of approximately 140 cases per 100,000 person-years in adults. The incidence of VTE has increased over the last decades, and more than 20% of affected individuals die in the first year after diagnosis. LÄS MER

  4. 8. Asymmetric Oligothiophenes : Chemical Evolution of Multimodal Amyloid Ligands

    Författare :Leif B.G. Johansson; Peter Nilsson; Peter Konradsson; Mikael Elofsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Luminescent conjugated polymers (LCPs) and luminescent conjugated oligothiophenes (LCOs) can be used as molecular probes to study diseases associated with protein aggregation. The conventionally used dyes to study and detect protein aggregates, denoted amyloid, have been Congo red (CR) and Thioflavin T (ThT). LÄS MER

  5. 9. Biochemical analysis of Pfh1, the essential Pif1 family helicase in Schizosaccharomyces pombe

    Författare :Jani B. Mohammad; Nasim Sabouri; Erik Johansson; Per Elias; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; G4; Pfh1; Genome integrity; helicase; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : DNA stores the genetic information of all living organisms, and this information needs to be copied accurately and passed on to each daughter cell when a cell divides. However, the DNA replication machinery often meets obstacles in the genome that cause fork pausing and might result in DNA damage. LÄS MER

  7. 10. Extended Förster Theory of Electronic Energy Transport within Pairs of Reorienting Chromophoric Molecules
