Molecular Characteristics of Carbapenem-Resistant Enterobacter cloacae in Ningxia Province, China.

abstract：:(S)-equol is one of the major metabolites of daidzein that is produced by human and animal gut bacteria. Most of the physiological functions of soybean isoflavones, such as anti-oxidative activity, anti-cancer activity, and cardiovascular protection have been ascribed to (S)-equol. However, only 30-50% people contain ...
