  1. 6. Evolving the Methodology for Detection of Primary DNA Damage : Development, adaptation and assessment of the single cell gel electrophoresis (comet) assay

    Författare :Erik Bivehed; Björn Hellman; Hanna Karlsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Comet assay; DNA damage; DNA strand breaks; Flash-comet; Genotoxicity; In vitro; Single cell gel electrophoresis; Polymerase assisted DNA damage assay PADDA ; TK6 cells; UCDAS; U937 cells; Toxikologi; Toxicology; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Deoxyribonucleic acid (DNA) is one of the most important molecules in nature. It is the fundamental carrier of evolutionary information and constitutes the genetic blueprint of all living organisms. Being the sole source of information, it is vital for the cell to transmit the correct genetic information from generation to generation. LÄS MER

  2. 7. Quantification of Radiation Induced DNA Damage Response in Normal Skin Exposed in Clinical Settings

    Författare :Martin Simonsson; Ingela Turesson; Gunilla Enblad; Dag Rune Olsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA damage response; low-dose hypersensitivity; dose response; normal tissue; epidermis; dermis; keratinocyte; fractionated radiotherapy; DNA double strand break; DSB; foci; gamma-H2AX; 53BP1; p21; checkpoint; apoptosis; mitosis; micro-RNA; miR-34a; Oncology; Onkologi; Oncology; Onkologi;

    Sammanfattning : The structure, function and accessibility of epidermal skin provide aunique opportunity to study the DNA damage response (DDR) of a normaltissue. The in vivo response can be examined in detail, at a molecularlevel, and further associated to the structural changes, observed at atissue level. LÄS MER

  3. 8. Biomarkers of internal exposure/dose : Methods to quantify adducts to protein and DNA by LC/MS studied with benzo[a]pyrene and isocyanates

    Författare :Emelie Westberg; Margareta Törnqvist; Kimmo Peltonen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biomarker; PAH; serum albumin; adduct; DNA; isocyanate; miljökemi; Environmental Chemistry;

    Sammanfattning : This thesis focuses on methods for quantification by liquid chromatography/mass spectrometry (LC/MS) of specific biomarkers for internal dose of chemicals which induce toxicity through their electrophilic reactivity. In vivo such compounds are short-lived, and could feasibly be measured as their reaction products (adducts) with biomacromolecules. LÄS MER

  4. 9. Genital human papillomaviruses. Studies of their occurrence, type spectrum and expression

    Författare :Ola Forslund; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mRNA expression; microwell; HPV 70; type determination; CIN; quantification; urine; multifocal infections; hybridization; PCR; HPV; human papillomavirus; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The occurrence of genital human papillomavirus infection was determined in different categories of patients by means of PCR. In high proportion of young women attending an adolescent clinic, the presence of HPV DNA was demonstrated in simultaneously urethral and cervical samples, suggesting that genital HPV infections are often multifocal.

  5. 10. Organic phosphorus speciation in environmental samples : Method development and applications

    Författare :Julia V. Paraskova; Per J.R. Sjöberg; Emil Rydin; William T. Cooper; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic phosphorus; DNA; phospholipids; inositol phosphates; sediment; soil; extraction; liquid chromatography LC ; mass spectrometry MS ; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Sammanfattning : This thesis investigates the development of new methodology for the identification and quantification of organic phosphorus compounds in environmental samples.Phosphorus is a vital element for primary production and one of the factors contributing to eutrophication. LÄS MER
