Scalable synthesis of A_2S_3 (A=Sb, Bi) submicro/nanowires using their powders via solvothermal proceeding

引用

Chinese Science Bulletin 2006年第6期51卷 655-660页

作者： JI Tianhao LIU Guanrao QI Xingyi YANG Qinglin DENG yuan guo lin Applied Chemistry Department School of Materials Science and Engineering Beijing University of Aeronautics and Astronautics Beijing100083 China

Single-crystal A2S3 (A=Sb, Bi) nanowires were successfully prepared via using their powders as precursors by solvothermal proceeding. The reac-tion temperature and time as well as solvent strongly influence final A2S3 crystalline morphology and size. Experimental results show that Sb2S3 rods prepared in ethylene glycol are thicker than its wires with av-erage diameter of 400 nm prepared in the mixture solvent of ethylene glycol and ethylenediamine at 200 oC for 24 h. However, under the same reaction con-dition, uniform submicrowires of Bi2S3 with average diameter of 150 nm can be obtained. When reaction temperature is decreased to 150 oC and reaction time is 40 h, pure Sb2S3 wires cannot be prepared. The possible mechanism is briefly discussed for the transformation of the Sb2S3 powders to their wire-like crystals.

Dyslipidemia in rat fed with high-fat diet is not associated with PCSK9-LDL-receptor pathway but ageing

引用

Journal of Geriatric Cardiology 2013年第4期10卷 361-368页

作者： Yan-Jun Jia Jun Liu yuan-lin guo Rui-Xia Xu Jiang Sun Jian-Jun Li Division of Dyslipidemia State Key Laboratory of Cardiovascular Disease Fu Wai Hospital National Center for Cardiovascular Diseases Chinese Academy of Medical Sciences Peking Union Medical College BeiLiShi Road 167 Beijing 100037 China

BACKGROUND: Obesity is associated with unfavorable alternations in plasma lipid profile and a broad spectrum of cardio-metabolic disorders。 Proprotein convestase subtilisin kexin type 9 (PCSK9) is a novel circulating protein that promotes hypercholesterolemia by decreasing hepatic low lipoprotein density receptor (LDLR) protein。 However, the relationship between PCSK9 concentration and lipid profile in an obesity condition has less been investigated。 OBJECTIVE: To examine the changes of plasma PCSK9 concentration in a rat model fed with high fat diet (HFD) and its correlation to lipid profile, body weight and ageing。 METHODS: Twenty male Sprague Dawley (SD) rats were divided into two groups, control group (fed with normal pellet for 4 weeks), and high-fat diet group (fed with 3% cholesterol enrich diet for 4 weeks)。 Blood samples of rats were obtained before and at days 14, 21, and 28 in both groups。 The body weight, plasma metabolic parameters (glucose, lipid profile) and PCSK9 were determined at indicated time points。 RESULTS: The body weights were significantly increased in rats fed with HFD compared to that in rats with normal pellets at day 28。 Additionally, total cholesterol (TC), triglyceride (TG), and low density lipoprotein cholesterol (LDL-C) levels in rat fed with HFD were also higher than that in rats fed with control diet while decreased high density lipoprotein cholesterol (HDL-C) levels were found in rats with HFD at day 28。 More interesting, there were no differences of plasma PCSK9 concentrations as well as hepatic expression of LDLR between the two groups at day 28。 CONCLUSIONS: Although the body weight and LDL-C were significantly increased in rats fed with HFD at 4 weeks, there were no differences of changes in plasma PCSK9 concentration and LDLR expression of liver tissue in both groups at baseline and day 28, suggesting that dyslipidemia in the rat model with HFD appears not to be associated with PCSK9-LDLR pathway but ageing。
