  2. 16. Effects of sex steroids on normal human breast : studies in vivo using microdialysis and in vitro in cell culture

    Author : Charlotta Dabrosin; Bo von Schoultz; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Prolonged exposure to sex steroids may constitute a risk factor for the development of breast cancer. The biological mechanisms involved in breast carcinogenesis are not well understood. READ MORE

  4. 17. Antibacterial effects of nitrite in urine

    Author : Stefan Carlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Nitrite; nitrate; nitric oxide; urinary tract infection; catheter-associated urinary tract infection; antimicrobial; Escherichia coli.;

    Abstract : Urinary tract infections (UTI`s) are among the most common conditions causing individuals to seek medical care. In addition, catheter-associated infections account for most of the hospital-acquired UTI´s and is also a major source of resistant nosocomial pathogens. READ MORE

  5. 18. Enzymatic synthesis of lipids containing omega-3 fatty acids

    Author : Ann-Marie Lyberg; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzymologi; Proteiner; enzymology; Proteins; Enzymes; DHA; EPA; Biotechnology; Bioteknik;

    Abstract : Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids, which have health promoting effects. Since they are highly prone to oxidation, they should be protected, in particular DHA. READ MORE

  6. 19. Towards More Specific Microcalorimetric Studies With Special Emphasis on Biological Systems

    Author : Peter Johansson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; isothermal heat conduction micro calorimetry spectrophotometry diode array pH oxygen titration chemical reaction biological bacteria perfusion photo carbon dioxide plant enthalpy Gibbs energy kinetic; Biology; Biologi;

    Abstract : A new approach in isothermal heat conduction microcalorimetric studies of chemical and biological processes is explored. The general (non-specific) method of calorimetry is combined with more specific analytical methods of analysis to "multi-functional microcalorimetric process monitors". READ MORE

  7. 20. Formation and role of nitric oxide in host defense reactions in the urinary bladder

    Author : Edward R I Morcos; Karolinska Institutet; Karolinska Institutet; []
    Keywords : bladder cancer; BCG; cytokines; urinary tract infection; nitric oxide; nitric oxide synthase; nitrite; nitrate; capillary electrophoresis;

    Abstract : Nitric oxide (NO) is an important biological mediator and cell signaling molecule. It is also involved in several host defense reactions. NO is formed in vivo from L-arginine by the enzyme NO synthase (NOS). However, it can also be formed non-enzymatically from acidified nitrite. READ MORE
