Application of traditional and reverse labeling approaches to assess dietary bioavailability of metals in biofilms

Environment International
The accuracy of stable isotope tracing techniques, traditional and reverse labeling, in evaluating metal bioavailability remains uncertain. This study employed pulse-chase feeding combined with multi-heavy-metal stable isotope labeling to compare the ...

Deletion of Genes Encoding Arginase Improves Use of "Heavy" Isotope-Labeled Arginine for Mass Spectrometry in Fission Yeast.

PLoS ONE, 2015
The use of "heavy" isotope-labeled arginine for stable isotope labeling by amino acids in cell culture (SILAC) mass spectrometry in the fission yeast Schizosaccharomyces pombe is hindered by the fact that under normal conditions, arginine is extensively ...

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

Advanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Ambient nitrate switches the ammonium consumption pathway in the euphotic ocean

Nature Communications, 2018
The underlying regulatory mechanisms of phytoplankton assimilation and microbial oxidation of ammonium in the surface ocean are unclear. Here, using isotope labeling experiments, the authors show that ambient nitrate is a key variable bifurcating ...

Atomic Scale Engineering of Multivalence‐State Palladium Photocatalyst for Transfer Hydrogenation with Water as a Proton Source

Advanced Materials, EarlyView.
Photocatalytic transfer hydrogenation is achieved over a multivalence‐state palladium photocatalyst, in which protons generated from photocatalytic water splitting are added to unsaturated double bonds. The operando light‐induced Electron Paramagnetic Resonance (EPR) spectroscopy confirms the synergistic action between Pd single atoms and nanoparticles,

Systematic NMR analysis of stable isotope labeled metabolite mixtures in plant and animal systems: coarse grained views of metabolic pathways.

PLoS ONE, 2008
BackgroundMetabolic phenotyping has become an important 'bird's-eye-view' technology which can be applied to higher organisms, such as model plant and animal systems in the post-genomics and proteomics era.

Photocatalytic Aqueous Reforming of Methyl Formate

Advanced Materials, EarlyView.
A 3d‐metal Cu‐based atomically dispersed photocatalyst, supported on modified g‐C₃N₄, facilitates the photocatalytic selective hydrogen (7.5 mmol gcat−1 of hydrogen; nothing else than H2 and CO2) generation from methyl formate. This diverse system functions under mild conditions, providing high hydrogen yield, selectivity, and enduring stability ...

General statistical framework for quantitative proteomics by stable isotope labeling.

Journal of Proteome Research, 2014
The combination of stable isotope labeling (SIL) with mass spectrometry (MS) allows comparison of the abundance of thousands of proteins in complex mixtures. However, interpretation of the large data sets generated by these techniques remains a challenge
