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. 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

5. 3. 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

6. 4. Hyperbaric oxygen treatment for pelvic radiation-induced injuries. From a multicenter randomized controlled trial to an experimental cell model

   Author : Nicklas Oscarsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyperbaric oxygen treatment; hyperbaric oxygen; late radiation-induced injury; cystitis; proctitis; reactive oxygen species; radiation therapy; quality of life;

   Abstract : Introduction Cancer is affecting a growing number of persons. Still, the treatment and survival of cancer is improving. Radiation therapy is used in the treatment of cancer. Late radiation-induced injuries afflict 5–15% of irradiated patients. READ MORE

7. 5. Redox effects on neutrophils in wound healing conducted by wound dressings and hyperbaric oxygen

   Author : Herman Sahlin; Göteborgs universitet; []
   Keywords : neutrophil granulocyte; wound healing; wound dressing; reactive oxygen species; NO; hyperbaric oxygen; bacterial killing;

   Abstract : The increased influx of neutrophils into chronic wounds results in increased production of reactive oxygen species (ROS), nitric oxide (NO) and lipid peroxidation products (LPP), as well as a ROS-induced increase in protease levels. The NO and LPP impair the respiratory burst response of the neutrophils and reduce their capacity to kill bacteria and digest debris. READ MORE
