Dibenzothiophene (DBT) and its derivatives can be microbially desulfurized by Dsz enzymes. We investigated the expressional characteristics of the dsz operon. The result revealed that the ratio of mRNA quantity of dszA, dszB, and dszC was 11:3.3:1; however, western blot analysis indicated that the expression level of dszB is far lower than that of dszC.(More)
Variation of anthocyanin and flavonol in Vaccinium uliginosum berry from seven locations in the Lesser Khingan Mountains was examined for the first time. A total of 14 anthocyanins and 10 flavonols were identified using HPLC-DAD and HPLC-ESI-MS(2) analysis. The composition of anthocyanins and flavonols in berries were the same in all of the locations(More)
Colonial aggregation of Microcystis plays a key role in bloom formation. Limited studies have been reported about effects of environmental factors on the aggregation of Microcystis. Calcium is an important chemical element in water system. In this study, we investigated the effects of a low- (0.015 g l−1) and a high-concentration of calcium (0.100 g l−1) on(More)
AIM Mangiferin is glucosylxanthone extracted from plants of the Anacardiaceae and Gentianaceae families. The aim of this study was to investigate the effects of mangiferin on Nrf2-antioxidant response element (ARE) signaling and the sensitivity to etoposide of human myeloid leukemia cells in vitro. METHODS Human HL-60 myeloid leukemia cells and(More)
We extended our previous genome-wide association study for psoriasis with a multistage replication study including 8,312 individuals with psoriasis (cases) and 12,919 controls from China as well as 3,293 cases and 4,188 controls from Germany and the United States and 254 nuclear families from the United States. We identified six new susceptibility loci(More)
Dibenzothiophene (DBT) and its derivatives can be microbially desulfurized by enzymes DszC, DszA, and DszB, which are encoded by the operon dszABC and contribute to the conversion in tandem. We investigated the expression characteristics of the dsz operon. Our results revealed that the levels of transcription and translation of dszA, dszB, and dszC(More)
Perillaldehyde (PAH), a major component of essential oil of Perilla Frutescens, has antidepressant-like effects and anti-inflammatory effects. The present study was designed to determine whether PAH is effective in treating lipopolysaccharide (LPS)-induced depression-like behavior in mice and to explore the possible mechanism between its antidepressant-like(More)
Animal bile is popularly used as a traditional medicine in China, and bile acids are their major bioactive constituents. In the present study, effects of bile extract from crocodile gallbladder on QBC939 cell growth, cell cycle, and apoptosis were investigated by MTT assay, inverted microscopy, fluorescence microscopy, transmission electron microscopy,(More)
AIM To investigate the effects of ESC-3 isolated from crocodile bile on the growth and apoptosis induction of human cholangiocarcinoma cells. METHODS ESC-3 was isolated from crocodile bile by Sephadex LH-20 and RP-18 reversed-phase column. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay was conducted to determine the effects of ESC-3(More)
Cytochrome P-450 2E1 CYP2E1 induction has been linked to oxidative stress in a number of experimental models. The aim of this study was to investigate the relationship between CYP2E1 activity and markers of oxidative stress and cardiac cell apoptosis during the development of alcoholic cardiomyopathy (ACM). Changes in left ventricular morphology were(More)
