Ecotoxicology and Environmental Safety, 2021 Stable isotope labeling of pollutants is a valuable tool to investigate their environmental transport and degradation. For the globally most frequently used herbicide glyphosate, such studies have, so far, been hampered by the absence of an analytical ...

Journal of Forest Science, 2008 We analysed stable isotopes of N in a spruce forest under ambient rainfall (no further manipulation of the atmospheric input) and clean rain application (10 years of reduced inorganic N- and acid-constituent input).

Production of Four 15N-Labelled Cobalamins via Biosynthesis Using Propionibacterium freudenreichii
Frontiers in Microbiology, 2021 Cobalamins (vitamin B12) are required by humans for their essential roles as enzyme cofactors in diverse metabolic processes. The four most common cobalamin vitamers are hydroxocobalamin (OHCbl), adenosylcobalamin (AdoCbl), methylcobalamin (MeCbl), and ...

Impact of two-bond 15N–15N scalar couplings on 15N transverse relaxation measurements for arginine side chains of proteins [PDF]
Journal of Biomolecular NMR, 2018 NMR relaxation of arginine (Arg) 15Nε nuclei is useful for studying side-chain dynamics of proteins. In this work, we studied the impact of two geminal 15N-15N scalar couplings on measurements of transverse relaxation rates (R 2 ) for Arg side-chain 15Nε nuclei.

Global Ecology and Conservation, 2022 In N-limited temperate regions of China, rates of atmospheric N deposition remain high during winter due to industrial development and energy consumption. Winter-deposited N accumulates and is then released after snowmelt.

Evaluation of deep root phenotyping techniques in tube rhizotrons
Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019 Selection for deep rooting is critical for the development of genotypes that are able to explore deep soil water and nutrients, particularly as agricultural resources become more limited.

Protein restricted diet during gestation and/or lactation in mice affects 15N natural isotopic abundance of organs in the offspring: Effect of diet 15N content and growth. [PDF]
PLoS ONE, 2018 OBJECTIVES AND STUDY:This study aimed at measuring the effect in normal to restricted protein diets with specific 15N natural isotopic abundance (NIA) given during gestation and/or lactation on the 15N NIA of fur, liver and muscle in dams and their ...
