| 1 | Magnesium deficiency in plants:An urgent problem显示文摘Although magnesium(Mg) is one of the most important nutrients, involved in many enzyme activities and the structural stabilization of tissues, its importance as a macronutrient ion has been overlooked in recent decades by botanists and agriculturists, who did not regard Mg deficiency(MGD) in plants as a severe health problem. However, recent studies have shown,surprisingly, that Mg contents in historical cereal seeds have markedly declined over time, and two thirds of people surveyed in developed countries received less than their minimum daily Mg requirement. Thus, the mechanisms of response to MGD and ways to increase Mg contents in plants are two urgent practical problems. In this review, we discuss several aspects of MGD in plants, including phenotypic and physiological changes, cell Mg2+homeostasis control by Mg2+transporters, MGD signaling, interactions between Mg2+and other ions, and roles of Mg2+in plant secondary metabolism. Our aim is to improve understanding of the influence of MGD on plant growth and development and to advance crop breeding for Mg enrichment. | Wanli Guo Hussain Nazim Zongsuo Liang Dongfeng Yang | 2016 | The Crop Journal2016，4，2： | 39 |
| 2 | Amelioration of Saline-Sodic Soils with Tillage Implements and Sulfuric Acid Application显示文摘Amelioration of saline-sodic soils through land preparation with three tillage implements (disc plow, rotavator and cultivator) each followed by application of sulfuric acid at 20% of gypsum (CaSO4·2H2O) requirement or no sulfuric acid application during crop growth period was evaluated in a field study for 2.5 years at three sites, i.e., Jhottianwala, Gabrika (Thabal), and Thatta Langar, in Tehsil Pindi Bhattian, Hafizabad District, Pakistan. Within 2.5 years, there was a decrease in the salinity parameters measured (electrical conductivity, pH, and sodium adsorption ratio), with a gradual increase in rice and wheat grain yields. It was observed that the disc plow, which not only ensured favorable yields but also helped improve soil health at all the three sites, was the most effective tillage implement. Also, application of sulfuric acid resulted in higher yields and promoted rapid amelioration of the saline-sodic soils. | M.SADIQ G.HASSAN S. M. MEHDI N. HUSSAIN M.

| 3 | Use of Biochar as an Amendment for Remediation of Heavy Metal-Contaminated Soils:Prospects and Challenges显示文摘Biochar(BC), known as the new black gold, is a stable, novel carbonaceous by-product that is synthesized through pyrolysis of biological materials in the absence of O_2.Recently, an emerging interest in the application of BC as a robust soil amendment has given rise to a broad research area in science and technology.It is considered a promising remediation option for heavy metal(HM)-contaminated soils to reduce HM bioavailability to plants.Remediation efficacy of BC depends on the porosity, composition,pyrolysis temperature, feedstock, and residence time of pyrolysis.This review article aimed to present an overview of BC use in the immobilization of HMs, i.e., Cd, As, Pb, Zn, Ni, Cu, Mn, Cr, and Sb, in contaminated soils.The remaining uncertain factors, including the specific soil HM immobilization mechanisms, long-term beneficial effects, and potential environmental risks associated with BC application are analyzed.Future research must be conducted to ensure that the management of environmental pollution is in accord with ecological sustainability and adaptation of the black gold biotechnology on a commercial basis for immobilization of HMs in contaminated soils. | Altaf Hussain LAHORI GUO Zhanyu ZHANG Zengqiang LI Ronghua Amanullah MAHAR Mukesh Kumar AWASTHI SHEN Feng Tanveer Ali SIAL Farhana KUMBHAR WANG Ping JIANG Shuncheng | 2017 | Pedosphere2017，27，6： | 28 |
| 4 | 不同硒源及水平对肉鸡组织硒含量及抗氧化功能的影响显示文摘本文旨在研究和比较不同硒源及水平对爱拔益加(AA)肉鸡生长性能、组织硒含量和抗氧化功能的影响,并探讨在生产中应用较低水平(0.20 mg/kg)有机硒替代较高水平(0.30 mg/kg)无机硒的可行性。选用1日龄AA肉仔鸡600只,随机分为5组,分别饲喂基础饲粮(对照组)及在基础饲粮中添加0.30 mg/kg硒(以亚硒酸钠形式)(SS组)、0.20 mg/kg硒(以酵母硒形式)(SYⅠ组)、0.30 mg/kg硒(以酵母硒形式)(SYⅡ组)和0.30 mg/kg混合硒(亚硒酸钠和酵母硒形式硒各0.15 mg/kg)(MS组)的试验饲粮,每组6个重复,每个重复20只鸡。试验期42 d。结果表明:1)SYⅡ组肉鸡前期平均日采食量显著低于对照组(P<0.05),饲粮添加各水平有机硒均显著降低了肉鸡全期平均日采食量(P<0.05或P<0.01)。2)与对照组和SS组相比,添加各水平有机硒均显著提高了肉鸡胸肌中的硒含量(P<0.01),且以SYⅡ组最高,显著高于其他各组(P<0.01);SYⅠ组和SYⅡ组肉鸡血浆中的硒含量显著高于对照组(P<0.05或P<0.01);添加各水平有机硒均显著提高了42 d肉鸡肝脏中的硒含量(P<0.05或P<0.01)。3)在试验前期(1~21 d),较SS组,SYⅡ组肉鸡血浆谷胱甘肽过氧化物酶(GSH-Px)和总超氧化物歧化酶(T-SOD)的活性均显著提高(P<0.05);较对照组,SS组、SYⅠ组和SYⅡ组肉鸡肝脏T-SOD的活性均显著提高(P<0.05或P<0.01)。在试验后期(22~42 d),较对照组,SS组、SYⅠ组和SYⅡ组肉鸡血浆和肝脏GSH-Px的活性均显著提高(P<0.05或P<0.01),各添加有机硒组肉鸡的血浆丙二醛含量均显著降低(P<0.05或P<0.01);与对照组相比,MS组肉鸡肝脏过氧化氢酶(P<0.05)和GSH-Px的活性均显著提高(P<0.01)。由此可知,饲粮添加0.30 mg/kg酵母硒能够提高肉鸡组织硒沉积量,对其生长性能和抗氧化功能的改善效果最佳;饲粮添加0.20 mg/kg的酵母硒替代0.30 mg/kg亚硒酸钠,在改善肉鸡的生长性能、提高组织硒含量和抗氧化功能方面是可行的。 | 田金可 Ahmad Hussain 李伟 高尚 王恬 | 2012 | 动物营养学报2012，24，6： | 23 |

| 13 | Recent advances in gel polymer electrolyte for high-performance lithium batteries显示文摘Lithium batteries (LBs) have become increasingly important energy storage systems in our daily life. However, their practical applications are still severely plagued by the safety issues from liquid electrolyte, especially when the batteries are exposed to mechanical, thermal, or electrical abuse conditions. Gel polymer electrolytes (GPEs) are being considered as an effective solution to replace currently available organic liquid electrolyte for building safer LBs. This review provides recent advancements in GPEs applied for high-performance LBs. On the one hand, from the environmental and economic point of view, the skeletons of GPEs changed from traditional polymer to renewable and degradable polymer. On the other hand, in addition to being as a component with good electrochemical and physical characterizations, the GPEs also need to provide some functions for addressing the concerns of lithium (Li) dendrites, unstable cathode electrolyte interface, dissolution and migration of transition metal ions,'shuttle effect' of polysulfides, and so on. Finally, to synchronously meet the challenges from the advanced cathode and Li metal anode, the bio-based GPEs with multi-functionality are proposed to develop high-energy/powerdensity batteries in the future. | Ming Zhu Jiaxin Wu Yue Wang Mingming Song Lei Long Sajid Hussain Siyal Xiaoping Yang Gang Sui | 2019 | Journal of Energy Chemistry2019，28，10： | 17 |

| 15 | Crop photosynthetic response to light quality and light intensity显示文摘Under natural conditions, plants constantly encounter various biotic and abiotic factors, which can potentially restrict plant growth and development and even limit crop productivity. Among various abiotic factors affecting plant photosynthesis, light serves as an important factor that drives carbon metabolism in plants and supports life on earth. The two components of light(light quality and light intensity) greatly affect plant photosynthesis and other plant's morphological, physiological and biochemical parameters. The response of plants to different spectral radiations and intensities differs in various species and also depends on growing conditions. To date, much research has been conducted regarding how different spectral radiations of varying intensity can affect plant growth and development. This review is an effort to briefly summarize the available information on the effects of light components on various plant parameters such as stem and leaf morphology and anatomy, stomatal development, photosynthetic apparatus, pigment composition, reactive oxygen species(ROS) production, antioxidants, and hormone production. | Iram SHAFIQ Sajad HUSSAIN Muhammad Ali RAZA Nasir IQBAL Muhammad Ahsan ASGHAR Ali RAZA FAN Yuan-fang Maryam MUMTAZ Muhammad SHOAIB Muhammad ANSAR Abdul MANAF YANG Wen-yu YANG Feng | 2021 | Journal of Integrative Agriculture2021，20，1： | 16 |

| 19 | Analysis of the delayed approach to the management of infected pancreatic necrosis显示文摘AIM: To analyze outcomes of delayed single-stage necrosectomy after early conservative management of patients with infected pancreatic necrosis (IPN) associated with severe acute pancreatitis (SAP). METHODS: Between January 1998 and December 2009, data from patients with SAP who developed IPN and were managed by pancreatic necrosectomy were analyzed. RESULTS: Fifty-nine of 61 pancreatic necrosectomies were performed by open surgery and 2 laparoscopically. In 55 patients, single-stage necrosectomy could be performed (90.2%). Patients underwent surgery at a median of 29 d (range 13-46 d) after diagnosis of acute pancreatitis. Sepsis and multiple organ failure accounted for the 9.8% mortality rate. Pancreatic fistulae (50.8%) predominantly accounted for the morbidity. The median hospital stay was 23 d, and the median interval for return to regular activities was 110 d.CONCLUSION: This series supports the concept of delayed single-stage open pancreatic necrosectomy for IPN. Advances in critical care, antibiotics and interventional radiology have played complementary role in improving the outcomes. | Nilesh Doctor Sujith Philip Vidhyachandra Gandhi Maharra Hussain Savio G Barreto | 2011 | World Journal of Gastroenterology2011，17，3： | 15 |
