  1. 1. Application and interpretation of biomarkers in ecotoxicology - from molecular to individual level responses

    Author : Sara Furuhagen; Elena Gorokhova; Carlos Barata; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomarkers; oxidative stress; ORAC; reproduction; Daphnia magna; toxicity; environmental stress; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The use of biomarkers is considered a promising alternative, or complement, to traditional ecotoxicological assays. Toxic effects are often initially manifested at the molecular or biochemical level, biomarkers are therefore used as sensitive indicators of toxic exposure. READ MORE

  2. 2. Oxidative Damage in Fish Used as Biomarkers in Field and Laboratory Studies

    Author : Bethanie Carney Almroth; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fish; oxidative stress; antioxidant enzymes; glutathione; protein carbonyls; lipid peroxidation; biomarkers; pollution; aging;

    Abstract : Many toxic xenobiotics entering into the aquatic environment exert their effects through redox cycling. Oxidative stress, incorporating both antioxidant defences as well as oxidative damage, is a common effect in organisms exposed to xenobiotics in their environment. READ MORE

  3. 3. Determination of biomarkers for lipid peroxidation and oxidative stress : Development of analytical techniques and methods

    Author : Kristina Claeson Bohnstedt; Bo Karlberg; Niels Heegaard; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary electrophoresis; mass spectrometry; electrospray; porous graphitic carbon; oxidative stress; lipid peroxidation; biomarker; malondialdehyde; hydroxynonenal; isoprostane; Analytical chemistry; Analytisk kemi;

    Abstract : Oxidative stress can be defined as a state of disturbance in the pro-oxidant/antioxidant balance in favour of the former, leading to potential damage. Processes associated with oxidative stress involve reactive oxygen species and radicals and can result in elevated levels of oxidatively modified or toxic molecules that can cause cellular malfunction, and even cell death.

  4. 4. Biomarkers of oxidative stress and their application for assessment of individual radiosensitivity

    Author : Siamak Haghdoost; Mats Harms-Ringdahl; Steffen Loft; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oxidative stress; 8-oxo-dG; 8-oh-dG; Radiosensitivity; Toxicology; Toxikologi;

    Abstract : Radiotherapy is one of the most common therapeutic methods for treatment of many types of cancer. Despite many decades of development and experience there is much to improve, both in efficacy of treatment and to decrease the incidences of adverse healthy tissue reactions. READ MORE

  5. 5. Improved environmental monitoring and assessment : Establishing links between effects of chemical pollution at different levels of biological organization in a Baltic Sea bioindicator species (Monoporeia affinis)

    Author : Martin Reutgard; Magnus Breitholtz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental health assessment; environmental monitoring; chemical pollution; hypoxia; bioindicators; biomarkers; teratogenicity; embryo toxicity; oxidative stress; acetylcholine esterase. Monoporeia affinis; Baltic Sea; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : A large number of chemicals enters the marine environment via atmospheric deposition, run-off, rivers and streams, industrial effluents and municipal wastewater. To understand how chemicals affect environmental health, monitoring and assessment approaches need to combine physical, chemical and biological effect parameters from different levels of biological organization.
