2016). However, the profiling of metabolites using electrospray ionization tandem mass spectrometry in mapping or GWAS (the sample size is quite large) is very costly and hence, is expensive to apply for a large sample size (Gieger et al. 2008; Gibon et al. 2012). Therefore, to study ...
Numerous analytical methods, such as elemental analysis, molar conductivity, electronic spectroscopy, infrared spectroscopy, mass spectrometry, magnetic susceptibility measurements, and thermogravimetric analysis, were used to confirm the chelation process and determine the structures of these complexes. The ...
Chromium(III) is extensively used as a supplement for muscle development and the treatment of diabetes mellitus. However, its mode of action, essentiality, and physiological/pharmacological effects have been a subject of scientific debate for over half a century owing to the failure in identifying t...
Meanwhile, high resolution mass spectrometry (HRMS) analysis of the reaction mixture also suggested the absence of potentially generated TEMPO-captured or BHT-captured THIQ radicals. These results, coupled with TEMPO's ability to act as a hydrogen atom transfer (HAT) agent, indicates that free ...
The individual components were unambiguously identified by direct comparison of GC- retention times and EI-mass spectra with those of authentic 3, 4, 5, and 1 that were generated from FPP in a separate incubation with recombinant S. coelicolor A3(2) germacradienol/geosmin synthase [15]. A ...

The Cu(II) and Zn(II) complexes were synthesized using Schiff base ligand by refluxing with CuCl2 and ZnCk A Schiff base ligand (L) was synthesized by condensing o-vanillin and 4-aminoantipyrine. The synthesized ligand and metal complexes were characterized by IR and mass spectrometry. The ...
Our group have reported a synthesis-free PET imaging strategy for BAT mass [58]. After a top-down screening with a number of 64Copper ligands through a PET scanner, we found that the combination of 64CuCl2 with an FDA-approved drug for alcoholism, disulfiram, provided a considerable high ...
The difference in the structure of tetrasubstituted metal phthalocyanines, which can be synthesized from different TPPN conformers, has been shown. Keywords: gas electron diffraction; mass spectrometry; DFT calculations; IR spectrum; molecular structure; 4-(4-tritylphenoxy)phthalonitrile; conformers 1....
