    Keywords : Medical sciences; homocysteine; methylenetetrahydrofolate reductase MTHFR ; first-ever stroke; first-ever myocardial infarction; longitudinal; prospective; risk factor; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Abstract : Abnormalities in homocysteine metabolism have been suggested as risk factors for stroke and myocardial infarction. In retrospective studies, elevated levels of total plasma homocysteine (tHcy) and/or methylenetetrahydrofolate reductase (MTHFR) 677C>T polymorphism have indicated an increase in risk. READ MORE

    Abstract : Background Cardiovascular diseases, including myocardial infarction and stroke, are the main reason of death in Sweden and Western Europe. High iron stores are believed to produce oxygen radicals, which is the presumed putative mechanism behind lipid peroxidation, atherosclerosis and subsequent cardiovascular disease. READ MORE

  4. 4. Nutritional aspects of behaviour and biology during pregnancy and postpartum

    Abstract : Background: Most errors in the venous blood testing process are preanalytical, i.e. they occur before the sample reaches the laboratory. Unlike the laboratory analysis, the preanalytical phase involves several error-prone manual tasks not easily avoided with technological solutions. READ MORE
