  1. 6. Airway antioxidant responses to oxidative air pollution and vitamin supplementation

    Författare :Annelie Behndig; Anders Blomberg; Ian S Mudway; Ragnberth Helleday; Isabelle Romieu; Umeå universitet; []
    Nyckelord :Medicine; air pollution; ozone; diesel exhaust; airway inflammation; antioxidant; vitamin C; dehydroascorbate; vitamin supplementation; Medicin; lungmedicin; Lung Medicine;

    Sammanfattning : Air pollutants, such as ozone (O3) and diesel exhaust particles, elicit oxidative stress in the lung. Antioxidants within the respiratory tract lining fluid (RTLF) protect the underlying tissue from oxidative injury. LÄS MER

    Sammanfattning : Diabetes mellitus in pregnancy causes congenital malformations in the offspring.The aim of this work was to characterize biochemical and morphologic anomaliesin the conceptus of an animal model of diabetic pregnancy. In addition, apreventive treatment against diabetes-induced dysmorphogenesis was developed. LÄS MER

  4. 8. Oxidative stress, antioxidative defence and outcome of gestation in experimental diabetic pregnancy

    Författare :Jonas Cederberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pregnancy; rat; ROS; free oxygen radicals; TBARS; isoprostanes; protein carbonyls; embryo; vitamin C; vitamin E; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Maternal type 1 diabetes is associated with an increased risk for foetal malformations. The mechanism by which diabetes is teratogenic is not fully known. Previous studies have demonstrated that radical oxygen species can contribute to the teratogenicity of glucose and diabetes. LÄS MER

  5. 9. Experimental and Clinical Studies of Oxidative Stress in Pre-Eclampsia

    Författare :Peppi Nash; Ulf Eriksson; Matts Olovsson; Leif Jansson; Lucilla Poston; Uppsala universitet; []
    Nyckelord :Obstetrics and gynaecology; Pre-eclampsia; Oxidative stress; Diabetes; Placenta; Rat; Antioxidants; Suramin; Vitamin E; Vitamin C; PAI-1; PAI-2; Obstetrik och kvinnosjukdomar;

    Sammanfattning : Impaired placentation and oxidative stress are proposed to play major roles in the pathogenesis of pre-eclampsia (PE). It has recently been pointed out that PE might be more than one disease and may have several different pathogeneses. LÄS MER
