3. 2. Biomarkers for DNA damage in human biomonitoring

   Författare :Natalia Kotova; Dag Jenssen; Jan Grawé; Lilianne Abramsson-Zetterberg; Mats Ljungman; Stockholms universitet; []
   Nyckelord :biomonitoring; biomarkers; DNA damage; cancer; diet; UV-light; molekylärgenetik; Molecular Genetics;

   Sammanfattning : Genomic DNA in humans is constantly exposed to different kinds of damage. Therefore, it is desirable to implement methods for detecting and measuring of inflicted body burden. Human biomonitoring (HBM) can here be a useful tool as a link between environmental exposure and disease outcome. LÄS MER

4. 3. Quantum Chemical Studies of Protein-Bound Chromophores, UV-Light Induced DNA Damages, and Lignin Formation

   Författare :Bo Durbeej; Leif Eriksson; Tim Clark; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; quantum chemistry; calculations; density functional theory; excited states; photochemistry; chromophores; absorption spectra; bathochromic shift; isomerization; UV radiation; DNA damages; cycloaddition reactions; photoenzymic repair; electron transfer; lignin; polymerization; phenoxy radicals; dilignols; Kvantkemi; Quantum chemistry; Kvantkemi;

   Sammanfattning : Quantum chemical methods have been used to provide a better understanding of the photochemistry of astaxanthin and phytochromobilin; the photoenzymic repair of UV-light induced DNA damages; and the formation of lignin. The carotenoid astaxanthin (AXT) is responsible for the colouration of lobster shell. LÄS MER

5. 4. Photosensitivity in cutaneous lupus erythematosus clinical and experimental studies

   Författare :Filippa Nyberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Lupus Erythematosus; skin; photosensitivity; polymorphous light eruption PLE ; adhesion molecules; ICAM-1; VCAM-1; E-selectin; fibroblasts; cytokines; UV light; UVA; UVB;

   Sammanfattning : Lupus erythematosus (LE) is an autoimmune disease in which the skin is one of the main target organs. Photosensitivity is a common feature for the different subtypes of cutaneous LE, but photosensitivity has not been well defined. LÄS MER

7. 5. Photochemistry of Eumelanin Precursors Role of Excited State Proton Transfer for UV Photoprotection

   Författare :Alice Corani; Kemisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time-resolved; Fluorescence spectroscopy; Excited State Proton Transfer ESPT ; Photochemistry; Eumelanin; Melanin;

   Sammanfattning : Melanin is an epidermal pigment commonly known to give darker skin coloration under sun exposure. It is also present in the hair, eyes, inner ear and brain. LÄS MER
