| 1 | Geochemical characteristics and applications of 18α(H)-neohopanes and 17α(H)-diahopanes显示文摘Distributions and geochemical significances of 18α(H)-neohopanes and of 17α(H)-diahopanes in oils from west Xialiaohe depression of the Bohai Bay Basin have been studied. Relative abundance of 18α(H)-neohopanes and of 17α(H)-diahopanes can be effectively used as maturity parameters, in a range of medium-high mature stage, based on consideration on sedimentary-organic facies of source rocks. With a dual geochemical significance of maturity and sedimentary-organic facies, neohopane and diahopane parameters can be well used in oil-source correlation and in petroleum population division. Formation, primary concentration and preservation of precursors of rearranged hopanes are closely related to depositional conditions such as Eh-pH and clays content. A series of probable diahopanes (series D) was detected in the oils, which exhibits a similar distribution pattern and geochemical behavior as that of 17α(H)-diahopanes (series B). | WANG Chunjiang, FU Jiamo, SHENG Guoying, XIAO Qianhua, LI Jinyou, ZHANG Yali & PIAO Mingzhi1.

| 2 | A β-glucosidase-producing M-2 strain: Isolation from cow dung and fermentation parameter optimization for flaxseed cake显示文摘Flaxseed cake contains cyanogenic glucosides, which can be metabolized into hydrocyanic acid in an animal's body, leading to asphyxia poisoning in cells. Beta-glucosidase is highly efficient in degrading cyanogenic glucosides. The Cattle may have b-glucosidase-producing strains in the intestinal tract after eating small amounts of flaxseed cake for a long time. This study aimed to isolate of a strain from cow dung that produces b-glucosidase with high activity and can significantly reduce the amount of cyanogenic glucosides. We used cow dung as the microflora source and an esculin agar as the selective medium. After screening with 0.05% esculin and 0.01% ferric citrate, we isolated 5 strains producing high amounts of b-glucosidase. In vitro flaxseed cake fermentation was fermented by these 5 strains, in which the strain M-2 exerted the best effect(P < 0.05). The strain M-2 was identified as Lichtheimia ramosa and used as the fermentation strain to optimize the fermentation parameters by a single factor analysis and orthogonal experimental design. The optimum condition was as follows: inoculum size3%, water content 60%, time 144 h, and temperature 32℃. Under this condition, the removal rate of cyanogenic glucosides reached 89%, and crude protein increment reached 44%. These results provided a theoretical basis for the removal of cyanogenic glucosides in flaxseed and the comprehensive utilization of flaxseed cake. | Chenhui Li Junshu Wei Yaping Jing Baoxia Teng Pingrong Yang Xinjun Chen Haiying Huang Tang Zhao Tuanjie Che Chunjiang Zhang | 2019 | Animal Nutrition2019，，1： | 5 |

| 4 | A deep learning-integrated phenotyping pipeline for vascular bundle phenotypes and its application in evaluating sap flow in the maize stem显示文摘Plant vascular bundles are responsible for water and material transportation, and their quantitative and functional evaluation is desirable in plant research. At the single-plant level, the number, size, and distribution of vascular bundles vary widely, posing a challenge to automatically and accurately identifying and quantifying them. In this study, a deep learning-integrated phenotyping pipeline was developed to robustly and accurately detect vascular bundles in Computed Tomography(CT) images of stem internodes. Two semantic indicators were used to evaluate and identify a suitable feature extraction network for semantic segmentation models. The epidermis thickness of maize stem was evaluated for the first time and adjacent vascular bundles were improved using an adaptive watershed-based approach. The counting accuracy(R^(2)) of vascular bundles was 0.997 for all types of stem internodes, and the measured accuracy of size traits was over 0.98. Combining sap flow experiments, multiscale traits of vascular bundles were evaluated at the single-plant level, which provided an insight into the water use efficiency of the maize plant. | Jianjun Du Ying Zhang Xianju Lu Minggang Zhang Jinglu Wang Shengjin Liao Xinyu Guo Chunjiang Zhao | 2022 | The Crop Journal2022，10，5： | 3 |
| 5 | Therapeutic potential of bone marrow-derived mononuclear cells for experimental cerebral ischemia in mice显示文摘Bone marrow mononuclear cells (BMMCs) can be directly harvested from the donor, allowing for easier application compared with bone marrow mesenchymal stem cells. The present study hypothesized that BMMC transplantation could ameliorate cerebral ischemia in a mouse model. BMMCs were double-labeled with PKH26 and 4', 6-diamidino-2-phenylindole (DAPI), followed by infusion into mice via the tail vein to induce focal cerebral ischemia. At 14 days after transplantation, morphological and neurofunctional recovery were analyzed. PKH26 and DAPI double-positive BMMCs were detected in the cerebral hemisphere of all transplantation mice. Following BMMC administration, there was significant difference in neurofunctional recovery, but no significant difference in survival rates between BMMC-treated mice and other mice. These results demonstrate that transplanted BMMCs migrate to brain tissue and | Xuemei Zhang Fang Du Dan Yang Chunjiang Yu Xiangnan Huang Wei Liu Jin Fu | 2010 | Neural Regeneration Research2010，5，23： | 3 |
| 6 | Grain size-dependent electrical resistivity of bulk nanocrystalline Gd metals显示文摘The electrical resistivity of the as-consolidated and coarse-grained bulk gadolinium(Gd) metals was studied in the temperature range of 3-315K.The experimental results showed that with decrease in the grain size of Gd grains from micrometer to nanometer range,the room temperature electrical resistivity increased from 209.7 to 333.0 μΩcm,while the electrical resistivity at the low temperature of 3K was found to increase surprisingly from 16.5 to 126.3 μΩcm.The room temperature coefficient resistivity(TCR) values were obtained as 39.2×10-3,5.51×10-3 and 33.7×10-3K-1.The ratios of room temperature to residual resistivity [RRR=ρ(300K)/ρ(3K)] are 2.64,11.0,respectively,for the as-consolidated samples at 280℃ and 700℃ with respect to that of the coarse-grained sample.All results indicate the remarkable influence of the nanostructure on the electrical resistivity of Gd due to the finite size effect and large fraction of grain boundaries. | Hong Zeng Ying Wu Jiuxing Zhang Chunjiang Kuang Ming Yue Shaoxiong Zhou | 2013 | Progress in Natural Science:Materials International2013，23，1： | 2 |
| 7 | Balance control of grid currents for UPQC under unbalanced loads based on matching-ratio compensation algorithm显示文摘In three-phase four-wire systems, unbalanced loads can cause grid currents to be unbalanced, and this may cause the neutral point potential on the grid side to shift. The neutral point potential shift will worsen the control precision as well as the performance of the threephase four-wire unified power quality conditioner(UPQC),and it also leads to unbalanced three-phase output voltage,even causing damage to electric equipment. To deal with unbalanced loads, this paper proposes a matching-ratio compensation algorithm(MCA) for the fundamental active component of load currents, and by employing this MCA,balanced three-phase grid currents can be realized under 100% unbalanced loads. The steady-state fluctuation and the transient drop of the DC bus voltage can also be restrained. This paper establishes the mathematical model of the UPQC, analyzes the mechanism of the DC bus voltage fluctuations, and elaborates the interaction between unbalanced grid currents and DC bus voltage fluctuations;two control strategies of UPQC under three-phase stationary coordinate based on the MCA are given, and finally, the feasibility and effectiveness of the proposed control strategy are verified by experiment results. | Xiaojun ZHAO Chunjiang ZHANG Xiuhui CHAI Jinlong ZHANG Fanqi LIU Zhe ZHANG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，6： | 2 |
| 8 | Forms of potassium and chlorine from oxy-fuel co-combustion of lignite coal and corn stover显示文摘In this work,the forms of potassium and chlorine from oxy-fuel co-combustion of lignite coal and corn stover under atmospheric pressure were investigated.In order to check transitional stage,the feedstocks were combusted stepwise,first by pyrolysis to form coke under N2 environment and later by coke combustion into the ash at 850℃ in O_(2)/CO_(2) atmosphere.The results show that an increase in blend ratio from 15%to 40%results in an increase in water-soluble potassium in the feedstock and the ashes from 0.15%to 0.4%and 0.015%to 0.038%in weight respectively.The water-soluble potassium is present mainly as KCl and K2SO4.For ammonium acetate soluble potassium,a similar trend to water-soluble potassium is presented but with a much lower content of potassium.The bound potassium in the fuel matrix exists,likely in the form of AlKSi_(2)O_(6).Chlorides are present mainly in the form of KCl which is the dominant water-soluble compound. | Chansa Oris Zhongyang Luo Wennan Zhang Chunjiang Yu | 2019 | Carbon Resources Conversion2019，2，2： | 2 |

| 10 | Physiological and Molecular Changes of Detached Wheat Leaves in Responding to Various Treatments显示文摘Leaf senescence is induced or accelerated when leaves are detached. However, the senescence process and expression pattern of senescence-associated genes (SAGs) when leaves are detached are not clearly understood. To detect senescence-associated physiological changes and SAG expression, wheat (Triticum aestivum L.) leaves were detached and treated with light, darkness, low temperature (4 C), jasmonic acid (JA), abscisic acid (ABA), and salicylic acid (SA). The leaf phenotypes, chlorophyll content, delayed fluorescence (DF), and expression levels of two SAGs, namely, TaSAG3 and TaSAG5, were analyzed. Under these different treatments, the detached leaves turned yellow with different patterns and varying chlorophyll content. DF significantly decreased after the dark, ABA, JA and SA treatments. TaSAG3 and TaSAG5, which are expressed in natural senescent leaves, showed different expression patterns under various treatments. However, both TaSAG3 and TaSAG5 were upregulated after leaf detachment. Our results revealed senescence-associated physiological changes and molecular differences in leaves, which induced leaf senescence during different stress treatments. | Lifeng Zhao Haoshan Zhang Bingjing Zhang Xiaojuan Bai Chunjiang Zhou | 2012 | Journal of Integrative Plant Biology2012，54，8： | 2 |
