| 1 | Effects of Artificial Aging on Physiological Characteristics of Rice Seeds with Different Dormancy Characteristics显示文摘In this study,two indica varieties with different dormancy characteristics [4 K58( II-32 B dormant),4 K59( II-32 B) ] and their F2 seeds( C178,C179) obtained through hybridization with sterile line( II-32 A) were used as materials. Different aged seeds( 0,3,6 and 9 d) of these four varieties were acquired by artificial accelerated aging method. Effects of artificial aging on malondialdehyde( MDA) content and catalase( CAT),ascorbate peroxidase( APX),peroxidase( POD) and superoxide dismutase( SOD) activity were investigated. The results showed that with the prolongation of aging time,MDA contents of these four rice varieties increased significantly,while the activity of antioxidant enzymes decreased dramatically. Besides,MDA contents and SOD,CAT and APX activity of the two inbred lines were significantly lower than those of the hybrid varieties. In addition,the activity of antioxidant enzymes in 4 K58 and C178 was significantly lower than that in 4 K59 and C179,respectively. This study indicated that artificial aging treatment significantly inhibited the activity of antioxidant system in seeds,improved membrane lipid peroxidation degree,and thus aggravated the deterioration of seeds. In addition,it also suggested that rice seeds with dormant property were more intolerant to storage. | Dongdong CAO Shanyu CHEN Yutao HUANG Yebo QIN Guanhai RUAN | 2019 | Agricultural Biotechnology2019，8，1： | 5 |
| 2 | A new approach for the aerobic oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid without using transition metal catalysts显示文摘The organic compound 2,5-furandicarboxylic acid(FDCA) has been identified by the US Department of Energy(DOE) as a valuable platform chemical for a wide range of industrial applications. Currently, the most popular route for FDCA synthesis is reported to be the oxidation of 5-hydroxymethylfurfural(HMF)by O_2 over the catalysis of noble metals(e.g., Au, Pt, Ru, and Pd). However, the high costs of noble metal catalysts remain a major barrier for producing FDCA at an industrial scale. Herein, we report a transition metal-free synthesis strategy for the oxidation of HMF to FDCA under O_2 or ambient air. A simple but unprecedented process for the aerobic oxidation of HMF was carried out in organic solvents using only bases as the promoters. According to the high performance liquid chromatography(HPLC) analysis, excellent product yield(91%) was obtained in the presence of NaOH in dimethylformamide(DMF) at room temperature(25 ℃). A plausible mechanism for the NaOH-promoted aerobic oxidation of HMF in DMF is also outlined in this paper. After the reaction, the sodium salt of FDCA particles were dispersed in the reaction mixture, making it possible for product separation and solvent reuse. The new HMF oxidation approach is expected to be a practical alternative to current ones, which depend on the use of noble metal catalysts. | Lu Zhang Xiaolan Luo Yebo Li | 2018 | Journal of Energy Chemistry2018，27，1： | 5 |
| 3 | Long-lived connection between the North China and North Australian cratons in supercontinent Nuna: paleomagnetic and geological constraints显示文摘It has been proposed by Zhang et al.[1] that the northern part of the North Chirm Craton (NCC) was connected to the north-western part of the North Australian Craton (NAC) in the Proterozoic, mainly based on the radial geometry of correlative -1.32 Ga dyke swarms in the two cratons (Fig. la). While the hypothetical connection between the NCC and the NAC was thought to be paleomagnetically permissible at ~1.80- 1.78Ga but w让h a slightly different configuration [2], the exact duration of either configuration is uncertain (e.g.,[2,3]). | Chong Wang Zheng-Xiang Li Peng Penga Sergei Pisarevsky Yebo Liu Uwe Kirscher Adam Nordsvan | 2019 | Science Bulletin2019，64，13： | 3 |
| 4 | 堆肥预处理对松木屑厌氧发酵的影响显示文摘针对目前针叶类林木松树厌氧发酵前预处理效果差、成本高的问题,在添加食品废弃物的条件下,研究好氧堆肥方法对松木屑(6.35 mm、9.53 mm和12.70 mm)和食品废弃物混合物料的预处理效果,以及对后续干式厌氧发酵过程的影响。研究结果表明,好氧堆肥过程对松木屑的预处理效果明显,但随着松木屑粒径的增大预处理效果降低;经堆肥预处理后物料的厌氧发酵原料的VS产气率均维持在199~215 L/kg范围内,约为未预处理组的1.4倍,而且发酵后物料中的VFA总量均维持在24.5左右,约为未堆肥预处理组的1.5倍,后续产气潜力更大。 | 王忠江 Yebo Li 赵佳 | 2014 | 农业机械学报2014，45，8： | 3 |

| 6 | Enhanced sympathetic activity and cardiac sympathetic afferent reflex in rats with heart failure induced by adriamycin显示文摘Our previous studies have shown that the cardiac sympathetic afferent reflex is enhanced in rats with chronic heart failure(CHF) induced by coronary artery ligation and contributes to the over-excitation of sympathetic activity.We sought to determine whether sympathetic activity and cardiac sympathetic afferent reflex were enhanced in adriamycin-induced CHF and whether angiotensin II(Ang II) in the paraventricular nucleus(PVN) was involved in enhancing sympathetic activity and cardiac sympathetic afferent reflex.Heart failure was induced by intraperitoneal injection of adriamycin for six times during 2 weeks(15 mg/kg).Six weeks after the first injection,the rats underwent anesthesia with urethane and α-chloralose.After vagotomy and baroreceptor denervation,cardiac sympathetic afferent reflex was evaluated by renal sympathetic nerve activity and mean arterial pressure(MAP) response to epicardial application of capsaicin(1.0 nmol).The response of MAP to ganglionic blockade with hexamethonium in conscious rats was performed to evaluate sympathetic activity.The renal sympathetic nerve activity and cardiac sympathetic afferent reflex were enhanced in adriamycin rats and the maximum depressor response of MAP induced by hexamethonium was significantly greater in adriamycin rats than that in control rats.Bilateral PVN microinjection of angiotensin II(Ang II) caused larger responses of the cardiac sympathetic afferent reflex,baseline renal sympathetic nerve activity and MAP in adriamycin rats than control rats.These results indicated that both sympathetic activity and cardiac sympathetic afferent reflex were enhanced and Ang II in the PVN was involved in the enhanced sympathetic activity and cardiac sympathetic afferent reflex in rats with adriamycin-induced heart failure. | Shujuan Zhang Feng Zhang Haijian Sun Yebo Zhou Ying Han | 2012 | The Journal of Biomedical Research2012，26，6： | 3 |
