  1. 21. Inactivation of pulmonary surfactant and its prevention

    Författare :Guido Stichtenoth; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pulmonary surfactant is a lipoprotein complex coating the conducting airways down to the terminal airspaces. Its main function is to lower surface tension at the air liquid interface thus preventing alveolar collapse at end expiration. LÄS MER

  3. 22. Electrochemistry, photoelectrochemistry and photoelectron spectroscopy of nanostructured metal oxides

    Författare :Sven Södergren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : Dye-sensitized nanostructured metal oxides are promising materials for solar energy conversion in photoelectrochemical solar cells. For nanostructured TiO2 electrodes, photocurrents were used to study the electron transport. In both steady state and time resolved measurements, the photocurrents could be described by diffusion of electrons. LÄS MER

  4. 23. All-ceramic Fixed Partial Denture. Studies on aluminum oxide- and zirconium dioxide-based

    Författare :Per Vult von Steyern; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental ceramics; dental porcelain; all-ceramic; fixed partial dentures;

    Sammanfattning : Keramiska material har länge använts inom tandvården för framställning av tandersättningar. Keramer har många goda egenskaper som gör dem särskilt lämpliga att använda i munnen. LÄS MER

  5. 24. On angiotensin II receptor type 2 receptors in the small intestine

    Författare :Sara Ewert; Göteborgs universitet; []
    Nyckelord :renin-angiotensin; angiotensin; small intestine; mucosa; epithelium; AT1; AT2; bradykinin; BK2 receptor; nitric oxide; iNOS; smooth muscle; contractility;

    Sammanfattning : The endocrine renin-angiotensin system (RAS) is important in the regulation of extracellular fluid volume and systemic blood pressure in strenuous conditions such as hypovolemia. Also present locally in peripheral tissues, all components of RAS are expressed and have been shown to modulate development, cell growth and inflammation. LÄS MER

  7. 25. Analysis of ginesenosides

    Författare :Jian-fang Cui; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : New analytical methods were developed in order to evaluate commercial ginseng preparations and to allow studies on urinary excretion of ginsenosides in humans after consumption of ginseng preparations. An optimized alkaline procedure was developed for cleavage of the glycosidic bonds that was clearly superior to previously reported hydrolysis procedures of ginsenosides because of (a) completeness of the reaction and (b) absence of the artifacts found in acid hydrolysis.
