1. 21. Characteristics of Particulate Emissions from Low Temperature Combustion and Renewable Fuels : Aerosol Mass Spectrometry of Refractory Carbonaceous Particles

   Författare :Vilhelm Malmborg; NanoLund: Centre for Nanoscience; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emissions; Soot; BC; BrC; ROS; SP-AMS; MiniCAST; Diesel Engine; HVO; RME; Cook Stove; Emissions; Soot; BC; BrC; SP-AMS; ROS; MiniCAST; Diesel Engine; HVO; RME; Cook Stove;

   Sammanfattning : Particulate air pollution is one of the major causes of premature death in the world, and combustion-derived soot emissions contribute strongly to the particulate pollution to which humans are exposed. Black carbon (BC) is one such emission and denotes soot with strong light absorption in the ultraviolet to infrared spectrum. LÄS MER

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

   Författare :Amanda Kessler; Inger Odnevall; Tommy Nylander; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 23. The Role of Reactive Oxygen Species in Animal Models of Autoimmunity

   Författare :Malin Hultqvist; Immunologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mice; Phytol; ROS; NOX; NADPH; p47phox; Ncf1; EAE; inflammation; Arthritis; RA; MS; Rats; Autoimmunity;

   Sammanfattning : Reactive oxygen species (ROS) produced by the phagocyte NADPH oxidase complex are important in the killing of invading pathogens. Lately, a role of ROS has been suggested in regulation of the immune system. LÄS MER

5. 24. Bioelectronic Approaches for On-Demand Generation of Reactive Oxygen Species

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

   Sammanfattning : 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. LÄS MER

7. 25. The oxidative stress response of Francisella tularensis

   Författare :Marie Honn; Anders Sjöstedt; Helena Lindgren; Andres Melendez; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella tularensis; FupA; MglA; OxyR; ROS; oxidative stress; molekylärbiologi; Molecular Biology;

   Sammanfattning : Francisella tularensis is capable of infecting numerous cell types, including professional phagocytes. Upon phagocytosis, F. tularensis resides within the phagosome before escaping into the cytosol to replicate. Phagocytes constitute a hostile environment rich in ROS, which are employed as a means of killing pathogens. LÄS MER
