Nitrogen Dioxide 13-16 NBL1, DAN family BMP antagonist Homo sapiens 18-21 7493969-6 1995 Adding superoxide dismutase to the medium markedly reduced the ratio of NO3- to NO2-, consistent with the hypothesis that NO3- in the medium results primarily from the extracellular reaction of NO with O2-.. Nitrogen Dioxide 80-83 NBL1, DAN family BMP antagonist Homo sapiens 122-125 8140629-8 1994 Measurement of plasma nitrite (NO2-) and nitrate (NO3-), which are the stable end products of NO, revealed that NO2- decreased about 50% after reperfusion (from 1.64 +/- 0.32 mumol/L to 0.80 +/- 0.17 mumol/L; P < 0.001), whereas NO3- levels remained unchanged (76 +/- 23 mumol/L vs. 63 +/- 8 mumol/L). Nitrogen Dioxide 112-115 NBL1, DAN family BMP antagonist Homo sapiens 50-53 8140629-8 1994 Measurement of plasma nitrite (NO2-) and nitrate (NO3-), which are the stable end products of NO, revealed that NO2- decreased about 50% after reperfusion (from 1.64 +/- 0.32 mumol/L to 0.80 +/- 0.17 mumol/L; P < 0.001), whereas NO3- levels remained unchanged (76 +/- 23 mumol/L vs. 63 +/- 8 mumol/L). Nitrogen Dioxide 112-115 NBL1, DAN family BMP antagonist Homo sapiens 232-235 34515997-3 2022 It was found that NO3 - ion is easily reduced into NO2 - and NOx and then further into N2 and NH3 (in the form of NH4 + ) in the process. Nitrogen Dioxide 51-54 NBL1, DAN family BMP antagonist Homo sapiens 18-21 1855835-8 1991 Thus, the effective amount of NO2- for 6 mmol NO3- ingested was calculated to be 18 mumol, and 33% of this nitrite was trapped by ingestion of 0.45 mmol thioproline. Nitrogen Dioxide 30-33 NBL1, DAN family BMP antagonist Homo sapiens 46-49 34529971-3 2022 It is an effective method to obtain NO2- by denitrifying the NO3-, including the by-product of Anammox. Nitrogen Dioxide 36-40 NBL1, DAN family BMP antagonist Homo sapiens 61-64 34529971-6 2022 The reduction of NO3- amount increased with an increase in Inf-NO3-, which was greater than that of NO2-. Nitrogen Dioxide 100-103 NBL1, DAN family BMP antagonist Homo sapiens 17-20 34529971-9 2022 This study showed that NO2- can be supplied by reducing the by-product NO3- with denitrification cathode at Anammox environment in-situ. Nitrogen Dioxide 23-27 NBL1, DAN family BMP antagonist Homo sapiens 71-74 34687681-10 2022 The data also indicated that as much as 80% of the removed NO3- was converted to NO2-, and this is noteworthy. Nitrogen Dioxide 81-85 NBL1, DAN family BMP antagonist Homo sapiens 59-62 34914357-6 2022 In addition, in situ differential electrochemical mass spectrometry (DEMS) indicated that ultrafast *NO2- to *NO reduction and highly selective *NO to *N2O or *N transformation played crucial roles during the NO3- reduction process. Nitrogen Dioxide 101-104 NBL1, DAN family BMP antagonist Homo sapiens 209-212 34874391-4 2021 Furthermore, analysis via a combination of experimental and theoretical methods revealed that the -OH group-functionalized samples reduce the energy barriers for conversion of the main intermediate (NO2), which is easily transformed to NO2-, thus accelerating the oxidation of NO to the final product (NO3-). Nitrogen Dioxide 199-202 NBL1, DAN family BMP antagonist Homo sapiens 302-305 34874391-4 2021 Furthermore, analysis via a combination of experimental and theoretical methods revealed that the -OH group-functionalized samples reduce the energy barriers for conversion of the main intermediate (NO2), which is easily transformed to NO2-, thus accelerating the oxidation of NO to the final product (NO3-). Nitrogen Dioxide 236-239 NBL1, DAN family BMP antagonist Homo sapiens 302-305 34328950-3 2021 We found that (1) changes in NO3 precursors (NO2 and O3) led to a significant increase in NO3 formation in the surface layer in winter but a decrease in summer; (2) a reduction in NOx promoted thermal equilibrium, favoring the formation of NO3 rather than dinitrogen pentoxide (N2O5). Nitrogen Dioxide 45-48 NBL1, DAN family BMP antagonist Homo sapiens 29-32 34328950-3 2021 We found that (1) changes in NO3 precursors (NO2 and O3) led to a significant increase in NO3 formation in the surface layer in winter but a decrease in summer; (2) a reduction in NOx promoted thermal equilibrium, favoring the formation of NO3 rather than dinitrogen pentoxide (N2O5). Nitrogen Dioxide 45-48 NBL1, DAN family BMP antagonist Homo sapiens 90-93 34328950-3 2021 We found that (1) changes in NO3 precursors (NO2 and O3) led to a significant increase in NO3 formation in the surface layer in winter but a decrease in summer; (2) a reduction in NOx promoted thermal equilibrium, favoring the formation of NO3 rather than dinitrogen pentoxide (N2O5). Nitrogen Dioxide 45-48 NBL1, DAN family BMP antagonist Homo sapiens 240-243 34506950-4 2021 Both animal and human experiments indicated that inorganic NO3- modulates the oral microbiome by increasing the abundance of health-associated NO3--reducing bacteria (e.g., Neisseria and Rothia) and decreasing the plenty of species Prevotella and Veillonella, leading to oral NO2- accumulation and improved systemic NO availability. Nitrogen Dioxide 276-280 NBL1, DAN family BMP antagonist Homo sapiens 59-62 15092051-4 1992 It is suggested that the most likely mechanism for this nitrate production was due to the solution of N2O5 and NO3 formed from the reaction of NO2 with O3. Nitrogen Dioxide 143-146 NBL1, DAN family BMP antagonist Homo sapiens 111-114 34086442-4 2021 The uptake process of NO2 on OA gives HONO as a reaction product, and the highest HONO production was observed upon the heterogeneous reaction of NO2 with OA in the presence of nitrate (NO3-) ions. Nitrogen Dioxide 22-25 NBL1, DAN family BMP antagonist Homo sapiens 186-189 34467355-2 2021 The generation of NO3 , however, is of grand demand due to the need of NO2 /O3, radioactive element, or NaNO3/HNO3 in the presence of highly energized electron/light. Nitrogen Dioxide 72-75 NBL1, DAN family BMP antagonist Homo sapiens 18-21 34086442-4 2021 The uptake process of NO2 on OA gives HONO as a reaction product, and the highest HONO production was observed upon the heterogeneous reaction of NO2 with OA in the presence of nitrate (NO3-) ions. Nitrogen Dioxide 146-149 NBL1, DAN family BMP antagonist Homo sapiens 186-189 34086442-5 2021 The formation of gaseous nitroaromatic compounds was also enhanced in the presence of NO3- ions upon light-induced heterogeneous processing of NO2 with OA, as revealed by membrane inlet single-photon ionization time-of-flight mass spectrometry (MI-SPI-TOFMS). Nitrogen Dioxide 143-146 NBL1, DAN family BMP antagonist Homo sapiens 86-89 24201842-1 1989 The hypothesis of NO2 (-) toxicity as the causative factor of NO3 (-) inhibition of nitrogenase (N2ase; EC 1.18.6.1) activity has been evaluated using a short-term exposure (3 d) of several legumes. Nitrogen Dioxide 18-21 NBL1, DAN family BMP antagonist Homo sapiens 62-65 35128037-8 2022 The wastewater analyses confirm the occurrence of nitrate (NO3 -), nitrite (NO2 -), and ammonia (NH4 +), which provide an appropriate condition for NO2 release. Nitrogen Dioxide 148-151 NBL1, DAN family BMP antagonist Homo sapiens 59-62 24201842-7 1989 It is concluded that NO2 (-) is not responsible for the initial NO3 (-)-induced decline of N2ase activity, and that toxic amounts of NO2 (-) only build up in nodules following longer exposures to NO3 (-), when this anion is actively reduced by bacteroid and cytosol enzymes. Nitrogen Dioxide 133-136 NBL1, DAN family BMP antagonist Homo sapiens 196-199 2509627-4 1989 In M phi and endothelial cells, citrulline and NO2-/NO3- are the stable endproducts of this metabolic pathway.

Nitrogen Dioxide 63-66 NBL1, DAN family BMP antagonist Homo sapiens 28-31 2851879-5 1988 The marked enrichment of H+, SO4(2-) and NO3- in precipitation compared with NH4+ could be explained by assuming either that SO2 and NO2 are oxidized in cloud droplets or that acidic sulfate and nitrate are scavenged directly in-cloud or below-cloud. Nitrogen Dioxide 133-136 NBL1, DAN family BMP antagonist Homo sapiens 41-44 3221192-5 1988 The effect of NO3- on methanogenesis was twofold: firstly, H2 accumulation decreased due to diversion of electrons towards NO3-/NO2- reduction, and as a result of H2 being used as an electron donor for NO3- reduction, resulting in the removal of the methanogenic substrate; secondly, there was direct inhibition of methane-producing bacteria by NO3- and NO2-.
