BACKGROUND AND AIMS: Expression of distinct types of myosin heavy chain (MHC) isoforms in skeletal muscle is accepted as one of critical factors providing the molecular basis of muscle fibre functional diversity and plasticity. However, chronic nerve stimulation experiments have provided a strong evidence that modifications in the contractile regulatory and the energy metabolism systems occur much...
Gas chromatography–mass spectrometry and gas chromatography with electron-capture detection have been investigated for analysis of per-sistent chlorinated aromatic compounds in the aquatic environment. A ran-ge of polychlorinated veratroles, guaiacols, and catechols produced during pulp bleaching and during PCB degradation were derivatized with penta-fluorobenzyl bromide to improve their chromatographic...
