Abstract
![]()
Selenium X-ray absorption
spectroscopy (XAS) has found widespread
use in investigations of Se-containing materials, geochemical processes,
and biologically active sites. In contrast to sulfur Kβ X-ray
emission spectroscopy (XES), which has been found to contain electronic
and structural information complementary to S XAS, Se Kβ XES
remains comparatively underexplored. Herein, we present the first
Se Valence-to-Core (VtC) XES studies of reduced Se-containing compounds
and FeSe dimers. Se VtC XES is found to be sensitive to changes in
covalent Se bonding interactions (Se–Se/Se–C/Se–H
bonding) while being relatively insensitive to changes in Fe oxidation
states as selenide bridges in FeSe dimers ([Fe2Se2]2+ vs [Fe2Se2]+). In
contrast, Se Kβ HERFD XAS is demonstrated to be quite sensitive
to changes in the Fe oxidation state with Se Kβ HERFD XAS demonstrating
experimental resolution equivalent to Kα HERFD XAS. Additionally,
computational studies reveal both Se VtC XES and XAS to be sensitive
to selenium protonation in FeSe complexes. Selenium is a trace element that plays
vital roles in biological
and geochemical cycles, energy storage, photovoltaics, and nanomaterials.
Herein, selenium Valence-to-Core X-ray emission spectroscopy is explored
as a new method of probing the chemical and electronic structure in
selenium-containing compounds, demonstrating sensitivity to selenium
bonding interactions. When paired with high-resolution Se X-ray absorption
spectroscopy (HERFD XAS), these two methods have the potential to
reveal greater insight into protonation and redox changes of Se-substituted
FeS clusters.

Abstract
When human hepatoma HepG2 cells were exposed to sodium selenite, an unknown selenium metabolite was detected in the cytosolic fraction by HPLC-inductively coupled plasma mass spectrometry (ICP-MS). The unknown selenium metabolite was also detected in the mixture of HepG2 homogenate and sodium selenite in the presence of exogenous glutathione (GSH). The unknown selenium metabolite was identified as selenocyanate by electrospray ionization mass spectrometry (ESI-MS) and ESI quadrupole time-of-flight mass spectrometry (ESI-Q-TOF-MS). Because exogenous cyanide increased the amount of selenocyanate in the mixture, selenocyanate seemed to be formed by the reaction between selenide or its equivalent, the product of the reduction of selenite, and endogenous cyanide. Rhodanase, an enzyme involved in thiocyanate synthesis, was not required for the formation of selenocyanate. Selenocyanate was less toxic to HepG2 cells than selenite or cyanide, suggesting that it was formed to reduce the toxicity of selenite. However, selenocyanate could be assimilated into selenoproteins and selenometabolites in rats in the same manner as selenite. Consequently, selenite was metabolized to selenocyanate to temporarily ameliorate its toxicity, and selenocyanate acted as an intrinsic selenium pool in cultured cells exposed to surplus selenite.

Abstract
Metallomics is newly coined terms and defined as a comprehensive analysis of the entirety of metal and metalloid species within a cell or tissue type. Then, metallome is defined as the entire category of metalloproteins and any other metal-containing biomolecules. Metallomics and research on metallome require analytical techniques that can provide information on the identification and quantification of metal/metalloid-containing biomolecules. This concept has been called speciation, and the acquisition of data according to the concept is performed using hyphenated techniques involving both separation and detection methods. In this review, the author intends to present several applications of complementary use of HPLC-inductively coupled plasma mass spectrometry (ICP-MS) and HPLC-electrospray ionization tandem mass spectrometry for identification of unknown selenium-containing metabolites, and also to present a newly developed technique, capillary LC-ICP-MS to be used for the analysis of metal-binding proteins.

Abstract
A method for the simultaneous speciation of selenoproteins and selenometabolites in human serum has been developed on the basis of in series three dimensional chromatography: size exclusion, affinity and anion exchange high performance liquid chromatography (3D/SE-AF-AEC-HPLC), using different columns of each type and hyphenation to inductively coupled plasma-(quadrupole) mass spectrometry (ICP-qMS). The method allows the quantitative simultaneous analysis of selenoprotein P (SeP), extracellular glutathione peroxidase (eGPx), selenoalbumin (SeAlb), selenite and selenate in human serum using species-unspecific isotope dilution (SUID). The 3D chromatographic separation is proposed to remove typical spectral interferences in this matrix from chloride and bromide on (77)Se ((40)Ar(37)Cl), (80)Se ((79)Br(1)H) and (82)Se ((81)Br(1)H). In addition, a previous method based on 2D/SE-AF-HPLC is proposed as a simple alternative when low molecular mass selenium species are absent in the samples. The method is robust, reliable and fast with typical chromatographic runtime less than 35min. Detection limits are in the range of 0.2-1.3ng of Seg(-1). Method accuracy for determination of total protein-bound to Se was assessed by analyzing an human serum reference material (BCR-637) certified for total Se content and method reliability checked in samples of human serum providing results in good agreement with the total selenium concentration. In addition, the application of the method to commercial human serum and plasma reference materials for quality control analysis, certified for total Se, has provided, for the first time, indicative levels of selenium containing proteins in these samples.
