The toxicity of herbicides to animals and human is an issue of worldwide concern. The present study was undertaken to evaluate toxic potential of widely used pesticide - glyphosate, its metabolites: aminomethylphosphonic acid (AMPA); methylphosphonic acid and its impurities: N-(phosphonomethyl)iminodiacetic

The mechanism of nucleation, steady-state growth, and repair is investigated for an oxygen evolving catalyst prepared by electrodeposition from Co(2+) solutions in weakly basic electrolytes (Co-OEC). Potential step chronoamperometry and atomic force microscopy reveal that nucleation of Co-OEC is progressive

The intracellular pH of Escherichia coli cells, respiring on endogenous energy sources, was monitored continuously by 31P NMR over an extracellular pH range between 5.5 and 9. pH homeostasis was found to be good over the entire range, with the

In large-scale phosphoproteomics studies, fractionation by strong cation exchange (SCX) or electrostatic repulsion-hydrophilic interaction chromatography (ERLIC) is commonly used to reduce sample complexity, fractionate phosphopeptides from their unmodified counterparts, and increase the dynamic range for phosphopeptide identification. However, these procedures

Reversible phosphorylations play a critical role in most biological pathways. Hence, in signaling studies great effort has been put into identification of a maximum number of phosphosites per experiment. Mass spectrometry (MS)-based phosphoproteomics approaches have been proven to be an
