  2. 16. High-performance liquid chromatography for analysis of 32P-postlabeled DNA adducts

    Author : Magnus Zeisig; Karolinska Institutet; Karolinska Institutet; []
    Keywords : DNA adducts; 32P-postlabeling; HPLC; method development;

    Abstract : The formation of DNA adducts, i.e. the covalent binding of chemicals and chemical groups to DNA, is believed to be an important step in chemical carciogenesis. DNA adducts are usually formed at very low levels which requires very sensitive methods to analyze them. READ MORE

    Abstract : Bauxite residue, also known as red mud, is produced in large quantities as a result of alumina refining (the first stage in aluminium production), and is one of the world’s most abundant and important industrial wastes. As demand for aluminium continues to increase and space to store this residue diminishes, the potential to utilise bauxite residue as a secondary resource is increasingly being considered by the alumina industry.

  5. 18. Methodological advancements in data analysis and quantitative performance of positron emission tomography

    Author : Martin Schain; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Positron emission tomography (PET) is a medical imaging modality with which neurophysiological functions can be studied. After a radio-labeled molecule is injected intravenously, it is transported by the blood stream to the target of interest. The radioactive atom of the molecule decays, resulting in two gamma rays that the PET system detects. READ MORE

  6. 19. Rapid analysis of actinide isotopes using quadrupole ICP-MS for emergency preparedness and environmental monitoring

    Author : Christina Greis; Stefan Karlsson; Bert Allard; Anders Düker; Håkan Pettersson; Gi-Hoon Hong; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; quadrupole ICP-MS; actinides; plutonium; preparedness; NATURAL SCIENCES; NATURVETENSKAP; Chemistry; Kemi; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Abstract : Transuranium elements in the environment are mainly derived from nuclear weapons testing and the nuclear fuel cycle. Of growing concern are illicit nuclear trafficking and the threat of terror acts. READ MORE

  7. 20. Reverse transcriptase assay for analysis of resistance to anti-HIV drugs and their mechanism of action

    Author : Xingwu Shao; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV-1; RT; antiviral drugs; NRTls; NNRTls; drug resistance; viral load;

    Abstract : Reverse transcriptase (RT) is a viral enzyme and one of the main targets for drugs against human immunodeficiency virus (HIV). This work presents a set of sensitive non-radioactive RT assays were developed: standard RT inhibition assay (IC assay); RT binding inhibition assay; RTprotein detection assay and template-primer destruction assay or chain termination assay (CT assay).
