  2. 1. Role of POU/Oct transcription factors in Drosophila immunity

    Author : Widad Dantoft; Ylva Engström; Anne Uv; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antimicrobial peptides; Drosophila; host-pathogen interaction; immune gene expression; immune signaling; NF-kB; microbiota; POU Oct transcription factors; protein degradation; stress response; transcriptional regulation; Molecular Biology; molekylärbiologi;

    Abstract : In response to infection, Drosophila melanogaster relies on the ability to mount a robust and potent innate immune response, characterized by induction of cellular and humoral processes. While rapid immune induction is of utmost importance, it is equally important to restrict and repress immune gene expression, where and when it is not needed. READ MORE

  4. 2. Enhancing UV-protection of clear coated wood by utilizing reactive UV-absorber and epoxyfunctionalized soybean oil

    Author : Sara Olsson; Mats KG Johansson; Emma Östmark; Mats Westin; Philip Evans; Minna Hakkarainen; Peter Weissenborn; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; UV-protaction; wood; clear coating; UV absorber; epoxy functionalized soybean oil; grafting;

    Abstract : This work presents the development of a new pretreatment for clear coated wood, that aims to increase the photoprotection of exterior wood products, and at the same time make the system more environmentally friendly. The pretreatment comprises the reactive UV absorber 2-hydroxy-4(2,3-epoxy­propoxy)-benzophenone (HEPBP), which has a primary epoxy group that can be covalently attached to the hydroxyl groups of the wood substrate.

  5. 3. Regulation of UV induced apoptosis in human melanocytes

    Author : Cecilia Bivik; Inger Rosdahl; Karin Öllinger; Maria Shoshan; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; apoptosis; UV; melanocyte; lysosome; cathepsin; Bcl-2; Bax; Hsp70; JNK; Dermatology and venerology; Dermatologi och venerologi;

    Abstract : Malignant melanoma arises from the pigment producing melanocytes in epidermis and is the most aggressive type of skin cancer. The incidence of malignant melanoma is increasing faster than any other type of cancer in white population worldwide, with a doubling rate every 10-20 years. READ MORE

  6. 4. Process Optimization of UV-Based Advanced Oxidation Processes in VOC Removal Applications

    Author : Francesco Montecchio; Klas Engvall; Roberto Lanza; Ernest Blatchley III; KTH; []

    Abstract : Polymeric materials are found in virtually all areas of daily life; they are found in everything from packages keeping our food safe to the buildings where we spend our days, and the production is a worldwide industry. Although polymeric materials play a big part in sustainable solution’s, a lot can be done to develop more environmental methods for producing them. READ MORE
