  1. 1. The oxidative stress response of Francisella tularensis

    University dissertation from Umeå : Umeå Universitet

    Author : Marie Honn; Umeå universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella tularensis; FupA; MglA; OxyR; ROS; oxidative stress; molekylärbiologi; Molecular Biology;

    Abstract : 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. READ MORE

  2. 2. Exosomes and the NKG2D receptor-ligand system in pregnancy and cancer using stress for survival

    University dissertation from Umeå : Umeå university

    Author : Malin Hedlund; Umeå universitet.; [2010]
    Keywords : Exsosomes; NKG2D; MICA; MICB; ULBP; human placenta; trophoblast; syncytiotrophoblast; thermal stress; oxidative stress; leukemia; lymphoma; immunologi; Immunology;

    Abstract : Although not obvious at first sight, several parallels can be drawn between pregnancy andcancer. Many proliferative, invasive and immune tolerance mechanisms that supportnormal pregnancy are also exploited by malignancies to establish a nutrient supply andevade or edit the immune response of the host.

  3. 3. Prostaglandins and Isoprostanes in Relation to Risk Factors for Atherosclerosis Role of Inflammation and Oxidative Stress

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johanna Helmersson; Uppsala universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Public health; prostaglandin F2α; F2-isoprostane; interleukin-6; C-reactive protein; serum amyloid A; tocopherols; cardiovascular risk factors; variation; inflammation; oxidative stress; human; Folkhälsomedicin; MEDICINE Social medicine Public health medicine research areas; MEDICIN Socialmedicin Folkhälsomedicinska forskningsområden;

    Abstract : Inflammation and oxidative stress may be involved in atherogenesis. This thesis describes clinical studies of prostaglandin F2α (PGF2α), an inflammatory mediator, and the isoprostane 8-iso-PGF2α, a reliable indicator of oxidative stress, and cytokine-related inflammatory mediators and indicators in healthy subjects and in a population-based cohort of Swedish men.

  4. 4. Effect of Dietary Antioxidants on Oxidative Stress, Inflammation and Metabolic Factors Studies in Subjects with Overweight and with Type 2 Diabetes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elisabet Rytter; Uppsala universitet.; Uppsala universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antioxidants; supplementation; fruit and vegetables; oxidative stress; isoprostanes; lipid peroxidation; oxidative damage to DNA; glycaemic control; inflammation; overweight; type 2 diabetes; MEDICINE; MEDICIN; Nutrition; Nutrition;

    Abstract : Observational studies have indicated that fruit and vegetables, and dietary antioxidants may play an important role in reducing the risk of chronic diseases, potentially by affecting pathogenic mechanisms such as oxidative stress and inflammation. Clinical trials investigating the effects of supplementation with single or a few antioxidants in high doses have, however, shown inconsistent results and thus have not been able to support the observational findings.
