(55). After 3 weeks the researchers noted a significantly increased resting fat burning (fat oxidation) and a 1.94 lb (0.88 kg) decrease in body fat (measured by the golden standard method DEXA). There was no change in body weight. This fat loss was seen despite that subjects were told...
3). Irrespective of the medium in question, no single analysis method, no matter how refined, is able to characterize the full chemical contents of a given sample. The use of multiple methods and analytical platforms, however, can greatly extend surveillance capabilities. A goal of ENTACT is ...
