Inhibition of the anammox activity by aromatic compounds [PDF]

open access: yes, 2015
The short-term effect of several aromatic compounds (o-cresol, p-nitrophenol, o-chlorophenol and quinoline) was evaluated over granular anammox sludge cultivated over 2 years in a Sequencing Batch Reactor (SBR). The anammox granular sludge had an average

Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

open access: yesAngewandte Chemie, EarlyView.
The human metabolism has been investigated for several millennia. The metabolome is known for a high complexity due to a large number of different metabolites that are present at different concentrations. Metabolomics has been developed as a field to investigate the entire human metabolome and to elucidate disease development mechanisms.

Urinary o-cresol in toluene exposure

open access: yesScandinavian Journal of Work, Environment & Health, 1979
The determination of urinary o-cresol in varying exposure to toluene vapor showed a linear relationship between the metabolite and the inhaled solvent. The analytical method involves acid hydrolysis of 20 ml of urine with subsequent extraction of the phenolic compounds in dichloromethane, followed by gas chromatographic analysis.

A Circular and Tacticity‐Independent Crystalline Mono‐Substituted Nylon‐6 Platform: Unexpected Large Positional Effects on Crystallizability and Performance

open access: yesAngewandte Chemie, EarlyView.
Methyl substitution positions on the nylon‐6 backbone markedly affect crystallizability, thermomechanical properties, and recyclability of the resulting atactic nylon‐6 variants. While γ‐methyl substitution gives an amorphous nylon, all other four methyl‐substitution positions (α, β, δ, and ε) afford, unexpectedly, crystalline nylons, showing tacticity‐
