Lime and Phosphate Could Reduce Cadmium Uptake by Five Vegetables Commonly Grown in South China

引用

Pedosphere 2011年第2期21卷 223-229页

作者： TAN Wan-Neng LI Zhi-An QIU Jing ZOU Bi LI ning-Yu zhuang Ping WANG Gang South China Botanical Garden Chinese Academy of Sciences Guangzhou 510650 (China)

A pot experiment was conducted in artificially Cd-contaminated （5 mg Cd kg 1） soils to investigate the feasibility of using lime （3 g kg-1） or phosphate （80 mg P kg-1） to mitigate uptake of Cd by vegetables. Five common vegetables in South China, including lettuce （Lactuca sativa L. var. ramosa Hort.）, Chinese cabbage [Brassica rapa L. subsp. Chinensis （L.） var. parachinensis （L. H. Bailey） Hanect], Chinese broccoli （Brassica oleracea L. vat. albiflora Kuntze）, white amaranth （Amaranthus tricolor L.） and purslane （Amaranthus viridis L.）, were grown in the soils and harvested after 60 d. The results showed that liming significantly reduced Cd uptake by most vegetables by 40%-50% （or a maximum of 70%）, mainly due to immobilization of soil Cd. Increased availability of Ca in the soil might also contribute to the Cd uptake reduction as a result of absorption competition between Ca and Cd. Liming caused biomass reduction in white amaranth and purslane, but did not influence growth of the other vegetables. Phosphate decreased Cd uptake by vegetables by 12% 23%. Compared with lime, phosphate decreased, to a smaller extent, the bioavailability of Cd in most cases. Phosphate markedly promoted growth of vegetables. Changes in soil chemistry by adding lime or phosphate did not markedly influence nutrient uptake of vegetables except that lime increased Ca content and phosphate increased P content in shoots of the vegetables. The results suggested that a proper application of lime could be effective in reducing Cd uptake of vegetables, and phosphate could promote growth of the vegetables as well as alleviate the toxicity of Cd.

In situ enhanced bioremediation of dichlorvos by a phyllosphere Flavobacterium strain

引用

Frontiers of Environmental Science & Engineering 2012年第2期6卷 231-237页

作者： Jiying ning Gang GANG Zhihui BAI Qing HU Hongyan QI Anzhou MA Xuliang ZHUAN Guoqiang zhuang Research Centre for Eco-Environmental Sciences Chinese Academy of SciencesBeijing 100085China

A bacterium capable of degrading dichlorvos was isolated from the rape phyllosphere and designated YD4. The strain was identified as Flavobacterium sp., based on its phenotypic features and 16S rRNA gene sequence. Strain YD4 was able to utilize dichlorvos as the sole source of phosphorus. In situ enhanced bioremedia- tion of dichlorvos by YD4 was hereafter studied. Chlorpyrifos and phoxim could also be degraded by this strain as the sole phosphorus source. A higher degradation rate of dichlorvos was observed after spraying YD4 onto the surface of rape leaves when compared to the sterilized- YD4 and water-treated samples. The results indicated that pesticide-degrading epiphytic bacterium could become a new way for in situ phyllosphere bioremediation where the hostile niche is unsuitable for other pesticide-degrading bacteria isolated from soil and water.

Nonlinear short-term heart rate variability prediction of spontaneous ventricular tachyarrhythmia

引用

Chinese Science Bulletin 2008年第16期53卷 2446-2453页

作者： zhuang JianJun ning XinBao DU SiDan WANG ZhenZhou HUO ChengYu YANG Xi FAN AiHua Key Laboratory of Modern Acoustics and Department of Electronic Science & Engineering Institute for Biomedical ElectronicEngineering Nanjing University Nanjing 210093 China Department of Medical Engineering Kunming People's Liberation Army General Hospital Kunming 650032 China

As malign ventricular tachyarrhythmias triggering sudden cardiac death (SCD), both ventricular tachycardia (VT) and ventricular fibrillation (VF) are major causes of mortality. The most efficient ther- apy for SCD prevention is implantable cardioverter defibrillators (ICD). The ICD can accurately and ef- fectively identify the forthcoming of fatal ventricular tachyarrhythmias and deliver a shock in order to restore patients’ normal sinus rhythm. In this study, two nonlinear complexity measures based on en- tropy: approximate entropy (ApEn) and sample entropy (SampEn) as well as two time linear indices: the mean RR interval (the average of time intervals between consecutive R-waves) and the standard devia- tion of RR intervals were used for short-term forecasting of VT-VF occurrence. The last small sections of interbeat intervals preceding 135 VT-VF episodes from 78 patients stored by the ICD were analyzed and compared with individually acquired control time series (CON series) from the same patients, which are normally intrinsic sinus rhythms. The results demonstrate that in addition to an obvious in- crease in heart rates of the patients, the values of two entropy measures are significantly smaller for VT-VF episodes than those for CON series. Conclusions can be drawn that when a ventricular tach- yarrhythmia approaches, the sympathetic tone of the patients is increased, and the complexity of their RR intervals immediately before the onset of VT-VF events is obviously lower than that of RR intervals recorded during sinus rhythms. For a better separation, the optimal range of threshold r is determined for two algorithms. ApEn and SampEn measures might be the suitable nonlinear parameters for short- term prediction of life-threatening ventricular tachyarrhythmias in the application of the cardioversion and defibrillation.

How does Bank Capital Affect Bank Profitability and Risk？ Evidence from China＇s WTO Accession

引用

China & World Economy 2015年第4期23卷 19-39页

作者： Chien-Chiang Lee Shao-Lin ning Chi-chuan Lee Department of Finance National Sun Yat-sen University Kaohsiung Taiwan School of Management Beijing Normal University Zhuhai Guangdong

This paper examines how bank capital affects bank profitability and risk in China, and how its impact differed before and after the nation entered the WTO. Our study uses the dynamic generalized method of moments approach with a panel database containing 171 Chinese commercial banks. We ftnd that bank capital has significant influence on bank profitability and risk, but its impact has declined since China joined the WTO in 2001. For different sized groups, the impact of capital on profitability exhibits a distinct trend. The effects of capital on bank risk are different for large and small banks depending on the risk variables used for the Chinese banking industry.

胶质瘤是最常见的原发性颅内肿瘤,具有极强的侵袭性和异质性,高达90%的原位复发率严重影响了患者的生活质量,并缩短了他们的生存期。为减少复发,胶质瘤切除术需要在保护脑功能的前提下尽可能切除瘤体并采取早期综合治疗。术中精确定位胶质瘤的边界和进行分子分型是实现这一治疗目标的关键。目前临床上广泛应用的病理学检测方法耗时长且很大程度上依赖临床医师和病理医师的主观判断。拉曼和太赫兹光谱都具有反映生物大分子结构的能力,在胶质瘤诊断领域得到广泛应用;二者在技术特点上的互补性可以帮助医师在术中精准定位胶质瘤边界的同时实现术中快速定性,以帮助医师采取合适的治疗手段。本文主要概括近年来拉曼光谱和太赫兹光谱技术在胶质瘤领域的研究进展和局限性,总结拉曼光谱-太赫兹光谱技术联用的研究现状及在胶质瘤诊断领域的研究进展,进一步展望二者联用在胶质瘤领域的发展前景。

Plant Temperature for Sterile Alteration of a Temperature-Sensitive Genic Male Sterile Rice,Peiai64S

引用

Agricultural Sciences in China 2007年第11期6卷 1283-1290页

作者： Lǖ chuan-gen ZOU Jiang-shi HU ning YAO Ke-min Jiangsu Academy of Agricultural Sciences Nanjing 210014 P.R.China Nanjing University of Information Science and Technology Nanjing 210044 P.R. China

The forecast of sterile alteration for the temperature-sensitive genic male sterile （TGMS） line in two-line hybrid rice seed production was traditionally based on screen temperature determined by weather station. The article put forward a new approach based on plant temperature, which was more exact and direct than the traditional method. The result of the simulation of the self-seeded setting rate of a widely used TGMS line, Peiai64S, by several temperature parameters and durations, showed that the fertility was directly affected by the plant temperature at a height of 20 cm or the air temperature around it in three days duration. Using the stem temperature of three days at a height of 20 cm as the simulation parameter, the fertility of Peiai64S had the maximum, minimum and optimum temperatures as 22.8, 21.7 and 22.5℃, respectively, whereas 23.2, 21.5 and 21.8℃ when using the air temperature of three days around the height of 20 cm as the parameter. Such temperature indices can be used to conclude the sterile alteration of TGMS for safeguarding seed production of twoline hybrid rice. The article also established a statistic model to conclude plant temperature by water temperatures at inflow and outflow, and air temperature and cloudage from weather station.
