This paper examines the value relevance of net income vs. impairment in Chinese listed agribusinesses. By linking valuation analysis with earnings time-series properties, we present additional evidence to support value relevance for listed agribusinesses: An earnings component is impounded in stock prices as long as it is persistent and no persistent impairment are value irrelevant. However, the time-series...
Imaging mass spectrometry based on matrix assisted laser desorption ionization-time of flight-mass spectrometry (MALDI-TOF-MS) for biological tissues was established. The key experimental factors were optimized as follows: 20 mg ml −1 of sinapic acid as matrix, ACN:H 2 O (1:1, v/v) as matrix solvent; MALDI-TOF-MS was operated at positive linear scan mode, 30%–50% of laser power range,...
Tetrandrine, a bisbenylisoquinoline alkaloid isolated from the dried root of Stephenia tetrandra (S Moore), possesses a remarkable pharmacological profile. However, the mechanisms of tetrandrine hepatotoxicity remain to be elucidated. In this study, we first proved apoptosis and mitochondrial dysfunction induced by tetrandrine in Sprague–Dawley rat liver in vivo. By further assuming apoptosis as an...
