TL;DR: The FIA method is found to be equally sensitive as NO measurement by means of oxyhemoglobin assay and seven times more sensitive than HPLC methods, and its design is significantly simpler than the traditional Griess method.

TL;DR: The basal concentration of nitrogen oxide in the plasma was reduced, at least in the peripheral circulation, in individuals with essential hypertension and the plasma nitrogen oxide concentration showed significant inverse correlations with both systolic and diastolic blood pressures.
Abstract: Patients with essential hypertension exhibit blunted endothelium-dependent vasodilator responses, which may be largely attributable to reduced bioactivity of nitric oxide (NO). Therefore, we measured the end product of NO, nitrate plus nitrite (nitrogen oxide), and examined the relationship between the degree of hypertension and plasma nitrate plus nitrite levels in patients with essential hypertension. The combined plasma concentration of nitrate plus nitrite, end products of NO metabolism, was reduced in individuals with essential hypertension relative to that in control subjects (15.7±1.1 versus 22.8±1.4 mmol · L−1, P <.001); individuals with borderline hypertension showed values that were intermediate between those of the other two groups (18.2±1.2 mmol · L−1, P <.001). The plasma nitrogen oxide concentration showed significant inverse correlations with both systolic and diastolic blood pressures. The basal concentration of nitrogen oxide in the plasma was reduced, at least in the peripheral circulation, in individuals with essential hypertension.

TL;DR: The viability of the electro-oxidation technology provided with boron doped diamond (BDD) electrodes for the treatment and reuse of the seawater used in a Recirculating Aquaculture System (RAS) was evaluated, observing that complete TAN removal together with important reductions of the other considered contaminants could be achieved, thus meeting the requirements for reuse of seawater in RAS systems.

TL;DR: In this paper, two different carbon substrates (ethanol and acetic acid) were compared in order to set up the denitrification of a concentrated industrial wastewater (115 mM nitrate, 0 mM nitrite).

TL;DR: Direct evidence for nitric oxide release in response to N-methyl-D-aspartate receptor activation in the adult cerebellar cortex is provided, in vivo, by coupling microdialysis with the azo dye detection method of Griess.
