2. 6. Nitric Oxide Exchange in Central and Peripheral Airways : Determinants in Health and Respiratory Disease

   Author : Andrei Malinovschi; Christer Janson; Kjell Alving; Lena Holm; Elisabeth Bel; Uppsala universitet; []
   Keywords : exhaled nitric oxide; alveolar NO; bronchial NO flux; extended NO analysis; asthma; smoking; snus; IgE-sensitization; pharyngo-oral tract; nitrate; nitrite; pulmonary hypertension;

   Abstract : Background: Exhaled nitric oxide (NO) is a marker of eosinophilic steroid-sensitive inflammation in the airways of patients with respiratory disease. Moreover, information about the localization of inflammation in the respiratory tree is obtained by estimates of bronchial and alveolar contributions to exhaled NO. READ MORE

4. 7. 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. 8. Structural and biochemical analysis of two copper proteins - plastocyanin from spinach and nitrite reductase from Rhodobacter sphaeroides 2.4.3

   Author : Frida Jacobson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plastocyanin; X-ray crystallography; nitrite reductase; copper geometry; redox; copper protein; photosynthesis; reduction potential; denitrification; electron transfer;

   Abstract : Plastocyanin from spinach and nitrite reductase from Rhodobacter sphaeroides 2.4.3 are two copper-containing proteins that are involved in biological electron transport chains: plastocyanin operates in photosynthesis and nitrite reductase takes part in the denitrification pathway.

6. 9. Nitrite ion : its role in vasoregulation and host defenses

   Author : Håkan Björne; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Nitrate; nitrite; nitric oxide; gastro protection; ventilator-associated pneumonia; bactericidal; vasodilation;

   Abstract : Nitrite and nitrate are distributed throughout the human body, with especially high levels being present in saliva. Until recently, these anions were considered merely to be inert end-products of the oxidation of endogenous nitric oxide (NO). READ MORE

7. 10. Nitrate, Nitrite and Nitric Oxide in Gastric Mucosal Defense

   Author : Joel Petersson; Lena Holm; Jon Lundberg; Mia Phillipson; Matthew Grisham; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE
