    Sammanfattning : Atherosclerosis is the primary cause of cardiovascular events such as angina pectoris and myocardial infarction, which together with stroke are responsible for around 50% of all deaths in the United States and Europe. Usually atherosclerosis develops over several decades and leads to a progressive narrowing of arterial vessels. LÄS MER

  3. 22. Renewable Energy in Energy-Efficient, Low-Pollution Systems

    Författare :Bengt Johansson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; ethanol; methanol; rape methyl ester; biomass; renewable energy; cogeneration; energy efficiency; scenarios; air pollution; carbon dioxide; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. LÄS MER

  4. 23. Spray drying of particles intended for inhalation - Investigation of significant process variables and product characteristics, with focus on degradation and solid state properties

    Författare :Kristina Mosén; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Läkemedelsteknik och relaterad teknik; Pharmaceutical and related technologies; carbohydrate; insulin; process conditions; crystallinity; degradation; particle size; spray drying; inhalation;

    Sammanfattning : The interest in spray drying for production of inhalable particles has grown considerably since the late 1980s. However, which process variables that control degradation and the solid state properties have not been subject to extensive research. This thesis deals with how important characteristics of inhalation particles can be controlled, i.e. LÄS MER

  5. 24. Helicobacter pylori infection in a mouse model: Development, optimization and inhibitory effects of antioxidants

    Författare :Xin Wang; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; virology; bacteriology; Microbiology; mice; Helicobacter pylori; gastritis; lymphoma; antioxidant; diet; Th1 and Th2; cytokines; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Helicobacter pylori is a human pathogen strongly associated with chronic type B gastritis, peptic ulcer disease, gastric cancer and MALT lymphoma. Our aims were to establish a mouse model of H. pylori infection, to study pathogenesis of gastritis and gastric cancer and to investigate new treatment strategies in this model. LÄS MER

  7. 25. Calcium transport in the Pacific oyster, Crassostrea gigas - in a changing environment

    Författare :Kirsikka Sillanpää; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate changes; Ussing chambers; Calcium uptake; Sodium potassium ATPase; Calcium ATPase; Sodium calcium exchanger; Calcium channel; Hemocytes; Mantle epithelium;

    Sammanfattning : Pacific oyster, Crassostrea gigas, is globally one of the most important farmed bivalve species. A prominent features of the C. gigas is the thick CaCO3 shell covering the body of the animal and protecting it from the environment. LÄS MER
