AIMS To isolate and characterize atrazine-degrading bacteria in order to identify suitable candidates for potential use in bioremediation of atrazine contamination. METHODS AND RESULTS A high efficiency atrazine-degrading bacterium, strain AD1, which was capable of utilizing atrazine as a sole nitrogen source for growth, was isolated from industrial(More)
This study aimed to investigate the protective effect of emodin on endoplasmic reticulum (ER) stress in rats with severe acute pancreatitis (SAP) and the underlying molecular mechanism. Sprague–Dawley male rats were randomly divided into sham operation group, SAP model group, and emodin treatment group. SAP was constructed through injecting sodium(More)
ETHNOPHARMACOLOGICAL RELEVANCE Neferine was isolated from green seed embryo of Nelumbo nucifera Gaertn which has been used as an anti-obesity agent in traditional Chinese herbal medicine. AIM OF THE STUDY This study was conducted to investigate the effects of neferine on enhancing insulin sensitivity in insulin resistant rats compared with rosiglitazone(More)

According to the theory of traditional Chinese herbal medicine, S. miltiorrhizae is always used in combination with borneol to obtain better pharmacological effects. The purpose of this study was(More)
ETHNOPHARMACOLOGICAL RELEVANCE Radix Aconiti Lateralis (Fuzi in Chinese, derived from the lateral roots of Aconitum Carmichaeli Debx.) is widely used for the treatment of heart failure, internal cold, arthralgia, diarrhea and edema for thousands of years. It was usually prescribed in combination with Rhizoma Zingiberis (Ganjiang in Chinese, derived from the(More)
UPLC-MS-MS system was used for the identification of arbidol metabolites in the rat feces, urine and plasma samples. The system was so powerful a way with high ability of separation and analysis, based on both chromatography and mass properties. The isotope of Br was also a good indicator for metabolites finding. There were altogether 9 metabolites detected(More)
Osteoporosis is a disease of bones that leads to an increased risk of fracture. Fructus of Psoralea corylifolia L. (scurfpea fruit) is commonly utilized for treating bone fractures and joint diseases for thousands of years in China. This study was aimed to screen active principles, which might have the potency to stimulate osteoblasts proliferation and(More)
Two new acetophenone derivatives were isolated from the roots of Euphorbia ebracteolata Hayata, their structures were elucidated as 2,4-dihydroxy-6-methoxyl-methylene-3-methyl-acetophenone (1) and 2-dihydroxy-6-methoxyl-methylene-3-methyl-acetophenone-4-O-beta-D-glucopyranoside (2) on the basis of chemical and spectroscopic methods including (1)D- and(More)
OBJECTIVE To develop an HPLC method for determining four components in Sini Tan, benzoylmesaconine, liquiritin, glycyrrhizic acid and 6-gingerol. METHOD The Hypersil BDS column was adopted with gradient elution program at a flow rate of 1.0 mL x min(-1) and the detection wavelength of 235 nm. RESULT Benzoylmesaconine, liquiritin, glycyrrhizic acid and(More)
Using data collected at the Pierre Auger Observatory during the past 3.7 years, we demonstrated a correlation between the arrival directions of cosmic rays with energy above 6 x 10(19) electron volts and the positions of active galactic nuclei (AGN) lying within approximately 75 megaparsecs. We rejected the hypothesis of an isotropic distribution of these(More)
