  1. 1. Lipid peroxidation in vivo Evaluation and application of methods for measurement

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Eva Södergren; Uppsala universitet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; lipid peroxidation; hydroperoxides; F2-isoprostanes; MDA; prostaglandins; measurement; carbon tetrachloride; vitamin E; dietary fat quality; rapeseed oil; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Geriatrics; geriatrik;

    Abstract : Lipid peroxidation is thought to be an important factor in the pathophysiology of a number of diseases and in the process of ageing, but its measurement in vivo has been difficult. The aim of this thesis was to evaluate methods for measurement of lipid peroxidation in vivo that are suitable for clinical investigations, and to apply these methods in animal and human studies investigating basal conditions and situations associated with increased lipid peroxidation.

  2. 2. Determination of biomarkers for lipid peroxidation and oxidative stress Development of analytical techniques and methods

    University dissertation from Stockholm : Institutionen för analytisk kemi

    Author : Kristina Claeson Bohnstedt; Stockholms universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary electrophoresis; mass spectrometry; electrospray; porous graphitic carbon; oxidative stress; lipid peroxidation; biomarker; malondialdehyde; hydroxynonenal; isoprostane; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi;

    Abstract : Oxidative stress can be defined as a state of disturbance in the pro-oxidant/antioxidant balance in favour of the former, leading to potential damage. Processes associated with oxidative stress involve reactive oxygen species and radicals and can result in elevated levels of oxidatively modified or toxic molecules that can cause cellular malfunction, and even cell death.

  3. 3. Measurement and Evaluation of Antioxidant Status and Relation to Oxidative Stress in Humans

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Cecilia Nälsén; Uppsala universitet.; [2006]
    Keywords : Nutrition; antioxidant; antioxidant status; antioxidant capacity; oxidative stress; lipid peroxidation; F2-isoprostanes; dietary factors; vitamin E; n-3 fatty acids; human; Näringslära;

    Abstract : Numerous diseases are associated with reduced antioxidant defence and oxidative stress. The antioxidant defence includes dietary and endogenous antioxidants and involves complex interactions between them. READ MORE

  4. 4. Milk Fat Intake and Conjugated Linoleic Acid (CLA) Supplementation Dietary Markers and Associations to Clinical and Biochemical Characteristics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

  5. 5. Homocysteine and Coronary Artery Disease With special Reference to Biochemical Effects Of Vitamin Therapy

    University dissertation from Department of Cardiology, Clinical sciences, Lund University

    Author : Torfi Jonasson; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; pyridoxine.; oxidative stress; lipid peroxidation; inflammation; homocysteine; endothelial function; folate; F2-isoprostanes; cystatine C; Acut coronary syndrome; cardiovascular disease; asymmetric dimethylarginine; cobalamine;

    Abstract : An elevated plasma level of homocysteine has been suggested as a risk factor for cardiovascular disease. The objectives of this thesis were to study the influence of renal function on homocysteine levels in patients with coronary artery disease and to explore the association of elevated plasma levels of homocysteine to oxidative stress, inflammation, and endothelial dysfunction.
