Variations of natural 15N abundances in the tissues and digesta of domestic animals.
The natural abundance of 15N (expressed as delta 15N per mil relative to air N2) in the tissues and the change of 15N abundance during the digestion processess in cattle, pig, and goat were investigated. The 15N abundances of cattle tissues differed by about 3.5% with high values in heart, urinary bladder and diaphragm. The ages of cattle did not affect on the 15N abundances of liver and kidney...
متن کاملSeasonal Variation of Earthworm Abundances and Biomass in Natural Forests and Plantations (North of Iran)
Soil productivity and plant growth are usually affected by biological activities of earthworms. The objective of this study was a comparative evaluation of earthworm abundances in 20-year-old plantations of Alder, Oak, Maple and Cypress with the adjacent natural mixed broad-leaved deciduous forest in the Caspian region of Iran. In this research one sample plot, each 1 ha; was selected in every ...
متن کامل[15N,1H]/[13C,1H]-TROSY for simultaneous detection of backbone 15N-1H, aromatic 13C-1H and side-chain 15N-1H2 correlations in large proteins.
This paper describes a [15N,1H]/[13C,1H]-TROSY experiment for the simultaneous acquisition of the heteronuclear chemical shift correlations of backbone amide 15N-1H groups, side chain 15N-1H2 groups and aromatic 13C-1H groups in otherwise highly deuterated proteins. The 15N-1H and 13C-1H correlations are extracted from two subspectra of the same data set, thus preventing possible spectral overl...
متن کاملRegional patterns of 15N natural abundance in forest ecosystems along a large transect in eastern China
The regional determining factors underlying inter- and intra-site variation of (15)N natural abundance in foliage, O horizon and mineral soil were investigated in eastern China.(15)N natural abundance values for these forest ecosystems were in the middle of the range of values previously found for global forest ecosystems. In contrast to commonly reported global patterns, temperate forest ecosy...
متن کامل13C and 15N natural isotope abundance reflects breast cancer cell metabolism
Breast cancer is the most common cancer in women worldwide. Despite the information provided by anatomopathological assessment and molecular markers (such as receptor expression ER, PR, HER2), breast cancer therapies and prognostics depend on the metabolic properties of tumor cells. However, metabolomics have not provided a robust and congruent biomarker yet, likely because individual metabolit...
