Determination of Nitrite and Nitrate by Forming Two 8-Hydroxyquinoline Based Azo Dyes [PDF]

شیمی کاربردی روز, 2012
Two sensitive and selective spectrophotometric methods are presented for the determination of trace amounts of nitrite and nitrate. It relies on the reaction of nitrite with sulfadimidine (SD) and cisapride (CP) in acidic medium to form diazonium ions ...

Nitrate decreases xanthine oxidoreductase-mediated nitrite reductase activity and attenuates vascular and blood pressure responses to nitrite

Redox Biology, 2017
Nitrite and nitrate restore deficient endogenous nitric oxide (NO) production as they are converted back to NO, and therefore complement the classic enzymatic NO synthesis.

Nebulization of the acidified sodium nitrite formulation attenuates acute hypoxic pulmonary vasoconstriction

Respiratory Research, 2010
Background Generalized hypoxic pulmonary vasoconstriction (HPV) occurring during exposure to hypoxia is a detrimental process resulting in an increase in lung vascular resistance. Nebulization of sodium nitrite has been shown to inhibit HPV.
