  2. 1. Delayed Cell Death after Traumatic Brain Injury : Role of Reactive Oxygen Species

    Author : Fredrik Clausen; Lars Hillered; Tiit Mathiesen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Traumatic Brain Injury; Reactive oxygen species; Fluid percussion injury; Controlled cortical impact; weight drop injury; Extracellular-signal regulated kinase; apoptosis; free radical scavenging; morphology; functional outcome; Neurovetenskap; Neurology; Neurologi;

    Abstract : Traumatic brain injury (TBI) is a leading cause of death and disability TBI survivors often suffer from severe disturbances of cognition, memory and emotions. Improving the treatment is of great importance, but as of yet no specific neuroprotective treatment has been found. READ MORE

  4. 2. Surface reactions on metallic nanoparticles : Ligand adsorption, metal release, and reactive oxygen species generation

    Author : Amanda Kessler; Inger Odnevall; Tommy Nylander; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metallic nanoparticles; ROS; reactive oxygen species; metal release; ligand adsorption; corrosion; Fenton like Haber Weiss reactions; metalliska nanopartiklar; ROS; reaktiva syreradikaler; metallfrisättning; adsorption; korrosion; Fenton lika Haber Weiss reaktioner; Kemi; Chemistry;

    Abstract : Humans are exposed daily to metallic nanoparticles (Me NPs) from multiple sources which can have both natural and anthropogenic origins. Such exposures take place via different routes including inhalation and skin contact and may result in adverse health effects. READ MORE

  5. 3. Reactive oxygen species as signalling molecules in immunity

    Author : Åsa Betten; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reactive oxygen species; NK cells; phagocytes; serotonin; histamine; myeloperoxidase;

    Abstract : Cytotoxic lymphocytes such as natural killer (NK) cells and subsets of T cells are key components of the host defense against malignancy and infection. Earlier studies have demonstrated that NK cells and several phenotypes of T cells become dysfunctional and apoptotic after exposure to autologous monocyte/macrophages and other phagocytes. READ MORE

  6. 4. Bioelectronic Approaches for On-Demand Generation of Reactive Oxygen Species

    Author : Eva Miglbauer; Eric Glowacki; Oliya Abdullaeva; Lars Peter Nielsen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ROS; ORR; WOR; Fenton reaction; Electrolysis; Bioelectronics;

    Abstract : Reactive oxygen species (ROS) are an integral part of our lives. They perform essential functions in our biology and are, due to their high oxidative power, key molecules in advanced oxidation processes in industrial applications such as treatment of wastewater. READ MORE

  7. 5. The role of reactive oxygen species in traumatic brain injury : Experimental studies in the rat

    Author : Niklas Marklund; Uppsala universitet; []
    Keywords : Medical sciences; Apoptosis; CBF; controlled cortical contusion injury; 3; 4-dihydroxybenzoate; fluid percussion injury; glucose; 4-hydroxybenzoate; microdialysis; Morris Water Maze; neuroprotection; nitrones; PBN; rat; reactive oxygen species ROS ; salicylate; S-PBN; TBI; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Neurosurgery; neurokirurgi;

    Abstract : Traumatic brain injury (TBI) is a major cause of mortality and disability. As common sequelae in survivors of TBI are disabling functional, emotional and cognitive disturbances, improved treatment of TBI patients is urgently needed. At present, no neuroprotective pharmacological treatment exists. READ MORE
