1. 1. Endothelial dysfunction in the pulmanory circulation after cardiopulmonary bybass : with special reference to the reactivity to acetylcholine

   Författare :Monika Angdin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Acetylcholine; acetylcysteine; allopurinol; antioxidants; cardiopulmonary bypass; heart surgery; L-arginine; nitric oxide; pulmonary circulation; reperfusion injury; vascular resistance; vitamin C; vitamin E.;

   Sammanfattning : The endothelium is important as a physical barrier between the bloodstream and the body tissues. It also plays an important role in the control of vasomotor tone, coagulation, and for the interaction between the vessel wall, leukocytes and platelets. One of the most important regulators released from the endothelium is nitric oxide (NO). LÄS MER

3. 2. Aspects of sepsis/SIRS - An experimental study on fluid therapy, vitamin C and plasma volume in increased permeability

   Författare :Björn Bark; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : In sepsis, after major surgery or severe trauma, the human body may suffer from various degrees of generalized inflammation, a syndrome called Systemic Inflammatory Response Syndrome (SIRS). One feature of SIRS is increased capillary permeability, caused by disruption of the capillary endothelium due to e.g. LÄS MER

4. 3. Pre-harvest factors affecting quality and shelf-life in raspberries and blackberries (Rubus spp. L.)

   Författare :Liaqat Ali; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Fruit including berries have been demonstrated to exhibit a broad spectrum of benefits including protection against cardiovascular, neurological, and lung diseases, as well as having antioxidant, antimicrobial, anti-inflammatory, anti- diabetic and anti-aging properties. These protective effects are reported to be due to their high content of bioactive compounds, such as vitamin C, vitamin E, phenolic acids, ellagitannins, flavonoids and carotenoids. LÄS MER

5. 4. 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

7. 5. Antioxidants from diet and supplements in relation to cardiovascular disease

   Författare :Susanne Rautiainen Lagerström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Many epidemiological studies have reported an inverse association between fruit and vegetable consumption and cardiovascular diseases (CVD). Because fruits and vegetables are high in antioxidants they were hypothesized to be one the factors responsible for the protective mechanisms. LÄS MER
