1. 6. Selenium Compounds in Milk. Studies of Selenoproteins, Selenium Enrichment and Oxidative Stability of Food

   Författare :Tien Hoac; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; Natural science; Copper; Zinc; Oxidative stability; Thioredoxin reductase; Glutathione peroxidase; Selenoproteins; Milk; Selenium supplementation; Technological sciences; Teknik;

   Sammanfattning : Selenium is an essential nutrient and in animals and humans it can either be specifically incorporated into proteins as selenocysteine or randomly as selenomethionine. It can also occur as low-molecular-weight compounds and the form of selenium in foods may also influence food quality. LÄS MER

3. 7. Experimental Helicobacter pylori infection in an animal model

   Författare :Yi-Qian Sun; Torkel Wadström; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Background: Helicobacter pylori is a microaerophilic Gram-negative bacterium colonizing the human stomach. The prevalence of this infection is between 20-90% depending on geographic location. Comprehensive studies have shown significant relationships between H. pylori infection and chronic gastritis, peptic ulcer and gastric carcinoma. LÄS MER

4. 8. Iron and macrophages in atherogenesis

   Författare :Xi Ming Yuan; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Oxidation of low density lipoprotein (LDL) may result in its uptake by macrophages and ensuing foam cell formation. Thus, oxidised LDL may play an important role in atherogenesis. Extensive in vitro evidences are in favour of the notion that LDL oxidation by cells present in atherosclerotic plaques requires the presence of transition metals. LÄS MER

5. 9. LDL Oxidation Susceptibility and Its Relation To Antioxidants and Fatty Acids : A Clinical and Experimental Study

   Författare :Bo Ziedén; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Atherosclerosis is an arterial disease characterized by lipid deposits in the artery wall. These lipid deposits partly consist of oxidatively modified low density lipoprotein (LDL). Several lines of evidence indicate a role of oxidized LDL in atherogenesis. LÄS MER

7. 10. Prevention of hemolysis as a novel strategy to limit hemoglobin-mediated lipid oxidation in fish - towards a more sustainable use of fish raw materials

   Författare :Semhar Ghirmai; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hemoglobin; herring Clupea harengus ; fish; rainbow trout Oncorhynchus mykiss ; erythrocyte; hemolysis; side-stream; antioxidant; lipid oxidation; blood plasma;

   Sammanfattning : Hemoglobin (Hb) has been recognized as a main pro-oxidant in fish, causing fast and intense lipid oxidation. This thesis explores the hypothesis that maintaining red blood cells (RBCs) intact for an extended time during fish processing could delay Hb-mediated lipid oxidation. LÄS MER
