  1. 1. Dietary inorganic nitrate : role in exercise physiology, cardiovascular and metabolic regulation

    Författare :Filip J. Larsen; Jon Lundberg; Eddie Weitzberg; Björn Ekblom; Victor M Darley-Usmar; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Medicin Teknik; Medicine Technology;

    Sammanfattning : Nitric oxide (NO) is a ubiquitous signaling molecule with a vast number of tasks in the body, including regulation of cardiovascular and metabolic function. A decreased bioavailability of NO is a central event in disorders such as hypertension and metabolic syndrome. LÄS MER

  3. 2. Nitrate, Nitrite and Nitric Oxide in Gastric Mucosal Defense

    Författare :Joel Petersson; Lena Holm; Jon Lundberg; Mia Phillipson; Matthew Grisham; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dietary nitrate; mucus gel layer; mucosal blood flow; mucus thickness; laser-Doppler flowmetry; mucosal damage; intra-vital microscopy; mucosal permeability; Physiology; Fysiologi;

    Sammanfattning : The human stomach normally contains high levels of bioactive nitric oxide (NO). This NO derives from salivary nitrate (NO3-) that is converted to nitrite (NO2-) by oral bacteria and thereafter non-enzymatically reduced in the acidic gastric lumen to NO. LÄS MER

  4. 3. 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

  5. 4. Mitochondrial efficiency : focus on dietary nitrate, hypoxia and exercise

    Författare :Tomas Schiffer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Metabolic efficiency affects weight control, generation of heat, exercise performance and health. The tiny radical nitric oxide (NO) targets several cellular components that can influence metabolic efficiency. NO is produced endogenously from L-arginine and molecular oxygen by specific NO-synthases. LÄS MER

  7. 5. Aspects on luminal nitric oxide in relation to oesophageal acid exposure and mucosal integrity

    Författare :Mogens Bove; Göteborgs universitet; []
    Nyckelord :nitric oxide; nitric oxide synthase; acid; gastro-esophageal reflux disease; membrane potentials; saliva; nitrate; blood flow; ferret; histopathology;

    Sammanfattning : Nitric oxide (NO) exerts important neuromuscular control of the oesophagus, but little is known about the sources and effects of the NO present in the distal oesophageal lumen. These questions were presently addressed in both human and animal experiments. LÄS MER
