A simple analytical procedure based on single-drop microextraction combined with in-syringe derivatization and GC-MS was developed for determination of some phenolic acids in fruits and fruit juices. Cinnamic acid, o-coumaric acid, caffeic acid, and p-hydroxybenzoic acid were used as model...

Expression of oncogenes or short telomeres can trigger an anticancer response known as cellular senescence activating the p53 and RB tumor suppressor pathways. This mechanism is switched off in most tumor cells by mutations in p53 and RB signaling pathways....

Trace analysis of phenolic compounds in water was performed by coupling single-drop microextraction (SDME) with in-syringe derivatization of the analytes and GC-MS analysis. The analytes were extracted from a 3ml sample solution using 2.5microl of hexyl acetate. After extraction, derivatization...
