  1. 6. Novel functions of cardiovascular P2 receptors

    Författare :Anna-Karin Wihlborg; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Kardiovaskulära systemet; mRNA; EDHF; UTP; UDP; ADP; ATP; P2 receptor; contraction; dilatation; endothelial cells; Heart; VSMC;

    Sammanfattning : The aim of the thesis was to examine the expression and function of the extracellular nucleotide P2 receptors in the cardiovascular system. In the cardiovascular system nucleotides are released during shear stress, hypoxia, ischemia, from endothelial cells, smooth muscle cells, aggregating platelets, inflammatory cells and erythrocytes.

  3. 7. Electromyography and bite force studies of muscular function and dysfunction in masticatory muscles

    Författare :Catharina Hagberg; []
    Nyckelord :Electromyography; bite force; contraction; isometric; masticatory muscles; mastication; intramuscular injections;

    Sammanfattning : Electromyographic (EMG) activity versus bite force was studied during a gradually increased isometric contraction up to maximal effort for patients with painful masseter muscles and referents. The masseter muscle, the anterior temporal muscle and the descending part of the trapezius muscle were chosen for the recordings. LÄS MER

  4. 8. The mechanisms controlling heat and mass transfer on frying of beefburgers

    Författare :Bea Kovácsné Oroszvári; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; permeability; porosity; contraction; frying; beefburger; heat and mass transfer;

    Sammanfattning : The aim of the present work was to gain better understanding of the mechanisms controlling heat and mass transfer during thermal processing of beefburgers. The effects of different factors such as the chemical composition and comminution of the meat raw material, the pan temperature and the meat patty diameter on the characteristics of heat and mass transfer were studied.

  5. 9. Endothelin receptor changes during inflammation in the lung

    Författare :Bengt Granström; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Andningsorganen; Respiratory system; Upregulation; Smooth muscle cells; Smoking; Sephadex; Remodeling; Rat; mRNA; Human; ETB receptor; ETA receptor; Lung; Endothelin; Asthma bronchiale; Contraction;

    Sammanfattning : Endothelin-1 (ET-1) is an extremely potent smooth muscle spasmogen well known from the vascular system but also active within the airways. The importance of its proinflammatory and co-mitogenic properties has become increasingly evident, the endothelin system also having been shown to mimic the signal features of asthma, COPD and other pulmonary diseases.

  7. 10. Dynamic Fetal and Placental Circulatory Changes during Uterine Contractions

    Författare :Hui Li; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexualitet; reproduktion; andrologi; gynekologi; Obstetrik; sexuality; reproduction; andrology; gynaecology; Obstetrics; Venous; Uterine; Umbilical; Resistance; Pregnancy; Oxytocin; Labor; IUGR; Flow; Doppler; Contraction; Brain-sparing; Cerebral;

    Sammanfattning : The best mode of delivery for fetuses with intrauterine growth restriction (IUGR) and umbilical artery (UA) blood flow changes is not well elucidated. Uterine artery, fetal UA, middle cerebral artery (MCA), and venous blood flow changes during uterine contractions during an oxytocin challenge test (OCT) have not been observed systemically. LÄS MER
