  2. 2. Modeling DNA Damage

    Författare :Patric Schyman; Aatto Laaksonen; Sason Shaik; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; DNA; Ionizing radiation; DNA radicals; Strand break; Hydrogen abstraction; Density Functional Theory; Car-Parrinello Molecular Dynamics; QM MM; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : In this thesis methods of computational chemistry have been used to examine DNA damaging processes initiated by ionizing radiation, free radicals, or Low-Energy Electrons (LEE). The computational chemistry method based on quantum mechanics that has been mainly used here is the Density Functional Theory (DFT). LÄS MER

  3. 3. Stability of bacterial DNA in relation to microbial detection in teeth

    Författare :Malin Brundin; Ulf Sjögren; Anders Johansson; David Figdor; Inge Fristad; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-bound DNA; cell-death; dentine; DNA binding affinity; DNA decomposition; DNA preservation; extracellular DNA; hydroxyapatite; PCR; polymerase chain reaction; odontologi; Odontology;

    Sammanfattning : The fate of DNA from dead cells is an important issue when interpreting results from root canal infections analysed by the PCR technique. DNA from dead bacterial cells is known to be detectable long time after cell death and its stability is dependent on many different factors. LÄS MER

  4. 4. Advances in DNA Detection

    Författare :Yajing Song; Olof Emanuelsson; Jonas Tegenfeldt; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA detection; active filter paper; visual detection; throughput; fluorescence; superparamagnetic beads; rare DNA; Q-PCR; chemical fragmentation; DNA library preparation; massively parallel sequencing; SRA - Molekylär biovetenskap; SRA - Molecular Bioscience;

    Sammanfattning : DNA detection technologies have an increasing importance in our everyday lives, with applications ranging from microbial diagnostics to forensic analysis, food safety evaluation, and environmental monitoring. Currently, as the associated costs decrease, DNA diagnostic techniques are routinely used in research laboratories, in clinical and forensic practice. LÄS MER

  5. 5. Development of benzoquinoquinoxaline derivatives as triplex-specific probes : Recognition of DNA structures at repeats sequences

    Författare :Helen Bergquist; Rula Zain; Keith Fox; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Triplex; H-DNA; BQQ; BQQ-OP; BQQ-Bodipy; triplet repeat; DNA; non-B-DNA; pkd1; frataxin; Friedreich s ataxia; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : Repeat sequences are associated with several human diseases, such as Friedreich’s ataxia, polycystic kidney disease and cancer. These sequences can form non-B-DNA structures, including triplex (H-DNA) DNA, and are associated with genomic instability and altered gene expression. LÄS MER
