| 1 | 甲烷化抑制剂在微生物电化学合成乙酸系统中的生物抑制效应显示文摘研究了利用2-溴乙烷磺酸钠(BES)选择性抑制产甲烷菌,从而提高微生物电化学系统合成乙酸产率的可行性,并对比了BES添加前后阴极室微生物菌群结构的变化。结果表明,厌氧混合菌接种物未经BES处理时甲烷是电化学系统CO_2还原的主导产物,最大生成速率达0.95 mmol·L^(-1)·d^(-1),8 d反应时间甲烷中电子回收率达55.0%,16S r RNA测序结果显示固态阴极的主要菌群为Methanobacteriaceae。BES的添加基本抑制了产甲烷菌的活动,使得乙酸成为主导产物,其合成速率最高达2.22 mmol·L^(-1)·d^(-1),系统总电子回收率达67.3%。Rhodocyclaceae(15.1%),Clostridiaceae(11.9%)、Comamonadaceae(11.1%)和Sphingobacteriales(11.0%)为主要菌群。研究结果表明了微生物电化学合成系统中抑制甲烷生成对调控微生态结构,从而调控电化学终产物的重要性。 | 戚玉娇 BRIDIER Arnaud DESMOND LE QUEMENERElie 吕凡 何品晶 BOUCHEZ Théodore | 2016 | 化工学报2016，67，5： | 3 |
| 2 | Diuretic and antioxidant activities of the aqueous extract of leaves of Cassia occidentalis(Linn.) in rats显示文摘Objective: To assess the putative diuretic and antioxidant properties of Cassia occidentalis(C. occidentalis) leaves' aqueous extract. Methods: Adult rats were administered with C. occidentalis leaves aqueous extract acutely(24-h) and subchronically(7 d), at doses 80, 160, 240, 320, and 400 mg/kg(per os). Negative control group received only an equivalent volume of distilled water, while the two positive control groups received the diuretic drugs furosemide(20 mg/kg, i.p.) and hydrochlorothiazide(HCTZ, 20 mg/kg, i.p.). Urinary elimination of electrolytes in response to treatments was evaluated, together with changes in concentrations of creatinine, urea, aldosterone, glucose, and albumin in urine and plasma. Various urinary indicators of kidney function and plasmatic markers of oxidative stress were also assessed. Results: The acute administration of C. occidentalis increased the urinary excretion of 107.58% at the higher dose tested, compared to negative control. The reference drugs furosemide and HCTZ induced increases of 84.27 % and 48.05 %, respectively. Acutely, the extract induced Na+ and Cl- elimination, whereas subchronically an increase in K+ elimination was also observed. The extract also improved the kidney function indexes and oxidative stress markers. These effects were dose-dependent and comparable with positive control observations. Conclusions: Our i ndings strongly suggest that C. occidentalis aqueous extract has diuretic and antioxidant activities, and deserves further studies considering the potential for the treatment of hypertension. | Théophile Dimo Fidèle Ntchapda Joseph Barama David Romain Kemeta Azambou Paul Faustin Seke Etet | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，9： | 2 |

| 20 | Electron paramagnetic resonance characterization of aluminum ion implantation-induced defects in 4H-SiC显示文摘Deep-level defects in silicon carbide(SiC)are critical to the control of the performance of SiC electron devices.In this paper,deep-level defects in aluminumion-implanted 4H-SiC after high-temperature annealingwere studied using electron paramagnetic resonance(EPR)spectroscopy at temperatures of 77 K and 123 K under different illumination conditions.Results showed that the main defect in aluminum ion-implanted 4H-SiC was the positively charged carbon vacancy(VC+),and the higher the doping concentration was,the higher was the concentration of VC+.Itwas found that the type of material defectwas independent of the doping concentration,although more VC+defects were detected during photoexcitation and at lower temperatures.These results should be helpful in the fundamental research of p-type 4H-SiC fabrication in accordance with functional device development. | Xiuhong Wang Zongwei Xua Mathias Rommel Bing Dong Le Song Clarence Augustine TH Tee Fengzhou Fang | 2019 | Nanotechnology and Precision Engineering2019，2，4： | 1 |
