  1. 1. Daphnids adaptive strategies to UV radiation

    University dissertation from Lund University, Faculty of Engineering

    Author : Carla Eloisa Fernández; [2018-04]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cladocera; Zooplankton; Andean lakes; Daphnia; Ultraviolet radiation; Migration strategy; Photo-protection;

    Abstract : This thesis focuses on the adaptive strategies of daphnids that allows them to maintain stable populations while deal with UV radiation, highlighting the differences in the responses that populations with different evolutionary histories may have.Although exposition to lethal doses in nature is unlikely, sub-lethal UV-B radiation doses may have strong impacts on zooplankton.

  2. 2. Intestinal Mucosa Reconstitution and Protection: Impact of Luminal Factors

    University dissertation from Department of Surgery, Clinical Sciences Lund, Lund University

    Author : Yilei Mao; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Probiotics; Pectin; Oat; Methotrexate; Lactobacilli; Intestinal injury; Intestinal immunity; Intestinal barrier; Enterocolitis; Fiber; Radiation; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Abstract : The gastrointestinal mucosa is one of the most rapidly proliferating tissues in the body, and serves as a barrier to luminal bacteria and toxins. Enteral nutrition, luminal fiber and probiotics are of crucial importance for the integrity of this barrier. READ MORE

  3. 3. Formation and repair of complex DNA damage induced by ionizing radiation

    University dissertation from Göteborg : University of Gothenburg

    Author : Karin Magnander; Göteborgs universitet.; Gothenburg University.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ionizing radiation; clustered damage; chromatin structure; DSB;

    Abstract : DNA is the critical target when cells are exposed to ionizing radiation, a potent stressor with capacity to produce complex DNA damages, thereby increasing the risk of cancer. DNA and associated histones form chromatin, which is an effective protection against ionizing radiation. READ MORE

  4. 4. Factors modifying cellular response to ionizing radiation

    University dissertation from Stockholm : Department of Molecular Bioscience, The Winner-Gren Institute, Stockholm University

    Author : Lei Cheng; Andrzej Wojcik; Siamak Haghdoost; Lovisa Lundholm; Penelope A. Jeggo; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radiation biology; DNA damage; gene expression; alpha particles; X-rays; mixed beams; gamma rays; hypothermia; dose rate.; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Many physical factors influence the biological effect of exposure to ionizing radiation, including radiation quality, dose rate and temperature. This thesis focuses on how these factors influence the outcome of exposure and the mechanisms behind the cellular response. READ MORE

  5. 5. A1M: a heme and radical binding protein. A study on structure, function and mechanisms

    University dissertation from Division of Infection Medicine

    Author : Sigurbjörg Rutardottir; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; α1-microglobulin; oxidative stress; heme; radiation; reactive oxygen species; preeclampsia;

    Abstract : This thesis describes functional and structural studies of the human protein α1-microglobulin (A1M), an evolutionarily well-conserved 26 kDa plasma and tissue protein mainly synthesized in the liver. A1M belongs to the lipocalin protein family. Lipocalins share a very similar structur, an 8-stranded β-barrel forming a hydrophobic pocket. READ MORE
