Quenching of Nitric Oxide by an Oral Carbonaceous Adsorbent

Kinetics of nitric oxide desorption from carbonaceous surfaces

We carried out a molecular modeling study of an important reaction in the combustion of nitrogen-containing chars, the evolution of nitric oxide, (CNO)!NO+(C*). Density functional theory at the B3LYP level was used to provide potential energy surface information and transition state theory was used to provide temperature dependant rate constants. Desorption of NO from nitrogen-containing carbon...

An Inducible Nitric Oxide

Transformation of Nitrite and Nitric Oxide Produced by Oral Bacteria to Reactive Nitrogen Oxide Species in the Oral Cavity

Nitrate and nitrite are present in the human oral cavity. The main origin of these components is nitrate that is contained in leafy vegetables such as lettuce and spinach (Tamme et al., 2006). Ingested nitrate is absorbed into human body by the intestine, and part of the absorbed nitrate is secreted into the oral cavity as a component of saliva. In the oral cavity, nitrate is reduced to nitrite...

Nitric oxide produced by endothelial nitric oxide synthase promotes diuresis.

Extracellular fluid volume is highly regulated, at least in part, by peripheral resistance and renal function. Nitric oxide (NO) produced by NO synthase type 3 (NOS 3) in the nonrenal vasculature may promote fluid retention by reducing systemic vascular resistance and arterial pressure. In contrast, NO produced by renal NOS 3 promotes water excretion by reducing renal vascular resistance, incre...

Nitric oxide produced by THAL nitric oxide synthase inhibits TGF.

Nitric oxide (NO) produced by neuronal NO synthase (nNOS) in the macula densa decreases tubuloglomerular feedback (TGF). NO produced by NOS in the thick ascending limb (THAL) inhibits NaCl transport. We hypothesized that NO produced by NOS in the THAL reaches the macula densa and inhibits TGF. Rabbit afferent arterioles and attached macula densa were simultaneously microperfused in vitro. TGF r...
