  1. 1. Interplay between Transcription and Homologous Recombination in the Presence of DNA Damage

    Författare :Ivaylo Stoimenov; Thomas Helleday; Niklas Schultz; Natalia Issaeva; Thierry Nouspikel; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; homologous recombination; transcription; DRB; UVC; 6-thioguanine; mammalian cells; BRCA1; BRCA2; PARP inhibitors; XP-V; Molecular biology; Molekylärbiologi; molekylärgenetik; Molecular Genetics;

    Sammanfattning : The biochemical processes of DNA repair, replication and recombination compete for the same substrate, the DNA molecule. This competition is natural, as each process requires the same template. In order to resolve possible conflicts between these processes, when they take place on a particular stretch of DNA, certain crosstalk is expected. LÄS MER

  2. 2. The role of MTH1 in ultraviolet radiation-induced mutagenesis

    Författare :Asal Fotouhi; Siamak Haghdoost; Harry Vrieling; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ultraviolet radiation; MTH1; reactive oxygen species; 8-oxo-dGTP; 2-OH-dATP; micronucleus; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Ultraviolet radiation (UVR) is known to be highly mutagenic. What types of DNA lesions that are induced by different UVR wavelengths are still a matter of debate. UVR induces mutagenesis mostly by the formation of photoproducts and the induction of reactive oxygen species (ROS). LÄS MER

  3. 3. PFAS in the water supply: source water contamination

    Författare :Dauren Mussabek; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; source water; drinking water; per- and polyfluoroalkyl substances; PFAS; AFFF; UV treatment;

    Sammanfattning : Water contamination with per- and polyfluoroalkyl substances (PFAS) is a serious problem for water suppliers in many regions. Due to persistence of the substances and a complex distribution mechanism, PFAS can have an adverse impact on water quality. LÄS MER

  4. 4. Towards Novel AlGaN-Based Light Emitters

    Författare :Martin Stattin; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AlGaN; light emitting diode; deep ultraviolet; III-Nitrides; near infrared; quantum cascade laser;

    Sammanfattning : The unique properties of the AlGaN semiconductors make them a suitable choice for optoelectronic devices at both short and long wavelengths, based on interband and intersubband transitions, respectively. What sets AlGaN apart from other wide-bandgap semiconductors is the possibility to obtain both p- and n-type conductivity as well as the direct bandgap. LÄS MER
