  1. 21. Nerve-induced release of nitric oxide in gastrointestinal and erectile tissue

    Författare :Katarina Hallén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Autonomic neurotransmission; cyclic guanosine monophosphate; guinea pig colon; neuronal nitric oxide synthase; nitric oxide; nitrite; phosphodiesterase; rabbit corpus cavernosum; smooth muscle; soluble guanylate cyclase;

    Sammanfattning : Nitric oxide (NO) is an important messenger of the autonomic nervous system, innervating the gastrointestinal and urogenital tracts among many other tissues. The aim of the present thesis was to study the nitrergic neurotransmission in enteric and erectile tissue with special emphasis on modulation of nitrergic neurotransmission by the soluble guanylate cyclase (sGC)/cyclic guanosine monophosphate (cGMP)-pathway.

  3. 22. The role of dietary nitrate in regulation of blood pressure and metabolism

    Författare :Michaela Sundqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A diet rich in vegetables is recommended for health in general and is also associated with lower blood pressure. Research suggests that inorganic nitrate present in leafy green vegetables could be a contributing factor for the favourable effect. LÄS MER

  4. 23. Exhaled nitrogen oxides and carbon monoxide in asthma and cystic fibrosis : markers of inflammation?

    Författare :Wilhelm Zetterquist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Exhaled markers of airway inflammation have attracted much interest as potential tools for monitoring the bronchial inflammation of respiratory disease. Exhaled nitric oxide (NO), its metabolites nitrite and nitrate in breath condensate (EBC), and exhaled carbon monoxide (CO), have been suggested for this purpose. LÄS MER

  5. 24. Dietary nitrate and the microbiota : modulators of metabolic function

    Författare :Chiara Moretti; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nitric oxide (NO) deficiency represents a known feature of cardiovascular and metabolic diseases as well as natural aging. The NO metabolites nitrate and nitrite have long been considered as health-threatening food components with potential carcinogenic effects. LÄS MER

  7. 25. Nitric oxide formation from inorganic nitrate and nitrate : contribution from eukaryotic and prokaryotic pathways

    Författare :Liyue Huang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nitric oxide (NO) is an essential signaling molecule that plays a central role in a broad range of physiological functions. Classically, NO is synthesized from L-arginine and molecular oxygen by NO synthases. Once formed, it is rapidly oxidized to nitrite and nitrate. LÄS MER
