  1. 6. p53 Alterations in Human Skin : A Molecular Study Based on Morphology

    Författare :Ling Gao; Christer Bush Bush; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; p53; skin; mutation; carcinogenesis; microdissection; UV; Basal cell cancer BCC ; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : Mutation of the p53 gene appears to be an early event in skin cancer development. The present study is based on morphology and represents a cellular and genetic investigation of p53 alterations in normal human skin and basal cell cancer. LÄS MER

  3. 7. Enhancing UV protection of clear coated exterior wood by reactive UV absorber and epoxy functional vegetable oil

    Författare :Sara Olsson; Mats Johansson; Gilles Sèbe; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Since ancient times wood has played a large role in human activities, both in terms of fuel and for construction purposes. A drawback with wood in exterior applications is, however, its susceptibility to photo-initiated degradation, caused by radiation from the sun. LÄS MER

  4. 8. Functional composite coatings containing conducting polymers

    Författare :Shadi Jafarzadeh; Per Martin Claesson; Arjan Mol; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Conducting polymer; Polyaniline; Conductive network; Nanocomposite; Active corrosion protection; Interfacial energy; UV curing; Kemi; Chemistry;

    Sammanfattning : Organic coatings are widely used to lower the corrosion rate of metallic structures. However, penetration of water, oxygen and corrosive ions through pores present in the coating results in corrosion initiation and propagation once these species reach the metal substrate. LÄS MER

  5. 9. Dermal exposure to UV-radiation and UV-curable acrylate coatings in the wood working industry

    Författare :Jouni Surakka; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : The work with UV radiation curable coatings (UV-coatings), increasingly used in the wood working industry, involves risks from skin exposure to hazardous UV-radiation and to harmful compounds in UV-coatings. The coatings contain acrylates that are known skin irritants and sensitizers. LÄS MER

  7. 10. Chemical and Dermatological Aspects of UV-absorbing Compounds

    Författare :Isabella Karlsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Contact Allergy; Photoallergy; Dibenzoylmethane; Octocrylene; Ketoprofen; Scytonemin;

    Sammanfattning : ABSTRACT The sun’s UV radiation is necessary for the existence of life on earth. However, too much UV exposure can lead to the development of skin cancer. Therefore, sunscreens are often used by the general population as protection from excessive UV radiation. LÄS MER
