Total Nitrogen Determination by a Spectrophotometric Method.
Koistinen J, Sjöblom M, Spilling K. Koistinen J, et al. Methods Mol Biol. 2020;1980:81-86. doi: 10.1007/7651_2019_206. Methods Mol Biol. 2020. PMID: 30734162
Being able to measure total nitrogen (TN) is important for following the nitrogen budget. In this chapter, we present the spectrophotometric method we use for determining TN. The method relies on oxidation and reduction steps, involving persulfate digestion of ni

Natural Nitrogenous Sesquiterpenoids and Their Bioactivity: A Review.
Chen DL, Wang BW, Sun ZC, Yang JS, Xu XD, Ma GX. Chen DL, et al. Molecules. 2020 May 27;25(11):2485. doi: 10.3390/molecules25112485. Molecules. 2020. PMID: 32471218 Free PMC article. Review.
Nitrogenous sesquiterpenoids fromnatural sourcesare rare, so unsurprisingly neither the potentially valuable bioactivity nor thebroad structural diversity of nitrogenous sesquiterpenoids has been reviewed before. ...This complete and in-depth reviewshouldbe helpful

The European perspective on nitrogen emission and deposition.
Erisman JW, Grennfelt P, Sutton M. Erisman JW, et al. Environ Int. 2003 Jun;29(2-3):311-25. doi: 10.1016/S0160-4120(02)00162-9. Environ Int. 2003. PMID: 12676218 Review.
Further reductions are necessary to reach critical limits for ecosystem protection, air quality standards, and climate change. Emissions of nitrogen compounds result from an overload of reactive nitrogen that is produced by combustion processes, by synthesis of ammo …

First-Principles Study of Nitrogen Adsorption and Dissociation on PuH(2) (111) Surface.
Wang C, Zhang K, Song P, Hu X, Mu J, Miao Z, Zhou J, He H. Wang C, et al. Molecules. 2020 Apr 19;25(8):1891. doi: 10.3390/molecules25081891. Molecules. 2020. PMID: 32325911 Free PMC article.
Plutonium mononitride is one of the main fuels for Generation IV reactors and can be prepared from nitrogenation of plutonium hydride. We investigated the adsorption and dissociation of nitrogen on PuH(2) (111) surface to elaborate the initial stage of nitrogenat

'Trophic' and 'source' amino acids in trophic estimation: a likely metabolic explanation.
O'Connell TC. O'Connell TC. Oecologia. 2017 Jun;184(2):317-326. doi: 10.1007/s00442-017-3881-9. Epub 2017 Jun 6. Oecologia. 2017. PMID: 28584941 Free PMC article. Review.
Amino acid nitrogen isotopic analysis is a relatively new method for estimating trophic position. ...I draw on isotopic tracer studies of protein metabolism, together with a consideration of amino acid metabolic pathways, to suggest that the 'trophic'/'source' groupings ha …

Air-breathing and excretory nitrogen metabolism in fishes.
Ip YK, Chew SF. Ip YK, et al. Acta Histochem. 2018 Oct;120(7):680-690. doi: 10.1016/j.acthis.2018.08.013. Epub 2018 Sep 2. Acta Histochem. 2018. PMID: 30180995 Review.
During water-land transition, ancient fishes acquired the ability to breathe air, but air-breathing engendered problems in nitrogenous waste excretion. Nitrogen is a fundamental component of amino acids, proteins, and nucleic acids, and the degradation of these n
