The effectiveness of ginseng in preventing and treating various central nervous system (CNS) diseases has been widely confirmed. However, ginsenosides, the principal components of ginseng, are characterized by poor accessibility to the brain, and this pharmacokinetic-pharmacological paradox remains poorly explained. Anti-inflammatory approaches are becoming(More)
The dopamine, serotonin, and kynurenine metabolic pathways play pivotal roles on brain function, and their disturbances are closely related to various neurological diseases. Comprehensive measurements of these metabolites is thus essential for monitoring the global neurochemical responses to pathological challenges or drug intervention. However,(More)
Although pharmacokinetic alternations by hepatic injury have been extensively studied, little is known about the potential influence of hepatoprotective agent's treatment. This study was aimed to investigate the holistic pharmacokinetics of multiple lignans, CYP3A regulations, and their correlations with hepatic injury biomarkers, in hepatic injured rats(More)
BACKGROUND AND PURPOSE Metabolites of the endocannabinoid, 2-arachidonoylglycerol (2-AG) have been postulated to act as endogenous activators of TRPV4, a Ca(2+) -permeable cation channel that plays a critical role in endothelium-dependent relaxation. However, it is unclear if TRPV4 contributes to the vascular actions of 2-AG. EXPERIMENTAL APPROACH(More)
This study was to develop and evaluate a practical approach of mass defect filtering (MDF), a post-acquisition data processing technique, for the rapid classification of complicated peaks into well-known chemical families based on the exact mass acquired by high resolution mass spectrometry. The full-scan LC-MS/MS data of the Ophiopogon japonicus extract(More)
BACKGROUND Studies on the relationship between thyroid function and non-alcoholic fatty liver disease (NAFLD) among euthyroid subjects have produced conflicting results. OBJECTIVES The aim of this study was to investigate the association between thyroid function and the presence of NAFLD in a large-sample middle-aged euthyroid subjects. METHODS A total(More)
This study was to systematically investigate the effect of mobile phase additives, including ammonia water, formic acid, acetic acid, ammonium chloride and water (as a control), on qualitative and quantitative analysis of fifteen representative ginsenosides based on liquid chromatography hybrid quadrupole-time of flight mass spectrometry (LC-Q-TOF/MS). To(More)
Metabolic research for herbal medicine (HM) is a formidable task, which is still in its infancy due to complicated components in HM, complex metabolic pathways, and lack of authentic standards. The present work contributes to the development of a powerful technical platform to rapidly identify and classify metabolites of herbal components based on a liquid(More)
Field experiments were conducted in two different locations to determine the dissipation pattern and residue levels of myclobutanil in tobacco leaves and soil. Myclobutanil 12.5 % microemulsion (ME) formulation was sprayed once at 3.0 mL/ha, and the residues in green tobacco leaves dissipated to more than 50 % of the initial deposits 5 days after(More)
Oral cancer is the sixth most common human cancer, with a high morbidity rate and an overall 5-year survival rate of less than 50%. It is often not diagnosed until it has reached an advanced stage. Therefore, an early diagnostic and stratification strategy is of great importance for oral cancer. In the current study, urine samples of patients with oral(More)
