APPLICATION AND DEVELOPMENT OF ‘GREEN’ PREVENTIVE AND CONTROL TECHNOLOGIES IN GUIZHOU TEA PLANTATIONS

《农业科学与工程前沿（英文）》 2022年第9卷第1期 doi: 0.15302/J-FASE-2021424

摘要：

The application and development of ‘green’ preventive technologies in tea plantations is an important means of ensuring tea quality and ecological safety. Ecological, agronomic and biological controls are the main preventive measures used in Guizhou Province. This paper summarizes the ‘green’ preventive technologies being applied in Guizhou tea plantations, including the use of plant defense inducers to regulate tea plant responses to pathogens, natural enemies to control pest species causing damage to shoots and Trifolium repens to control the main weed species. In addition, it summarizes the integrated ‘green’ preventive technologies being used in Guizhou and provides a foundation for the ecological maintenance of tea plantations.

Triterpenoid inducers of Nrf2 signaling as potential therapeutic agents in sickle cell disease: a review

null

《医学前沿（英文）》 2015年第9卷第1期页码 46-56 doi: 10.1007/s11684-015-0375-1

摘要：

Sickle cell disease (SCD) is an inherited disorder of hemoglobin in which the abnormal hemoglobin S polymerizes when deoxygenated. This polymerization of hemoglobin S not only results in hemolysis and vaso-occlusion but also precipitates inflammation, oxidative stress and chronic organ dysfunction. Oxidative stress is increasingly recognized as an important intermediate in these pathophysiological processes and is therefore an important target for therapeutic intervention. The transcription factor nuclear erythroid derived- 2 related factor 2 (Nrf2) controls the expression of anti-oxidant enzymes and is emerging as a protein whose function can be exploited with therapeutic intent. This review article is focused on triterpenoids that activate Nrf2, and their potential for reducing oxidative stress in SCD as an approach to prevent organ dysfunction associated with this disease. A brief overview of oxidative stress in the clinical context of SCD is accompanied by a discussion of several pathophysiological mechanisms contributing to oxidative stress. Finally, these mechanisms are then related to current management strategies in SCD that are either utilized currently or under evaluation. The article concludes with a perspective on the potential of the various therapeutic interventions to reduce oxidative stress and morbidity associated with SCD.

Polyamines and antioxidant defense system are associated with cold tolerance in centipedegrass

Jingjing CHEN, Junyang FANG, Zhenfei GUO, Shaoyun LU

《农业科学与工程前沿（英文）》 2018年第5卷第1期页码 129-138 doi: 10.15302/J-FASE-2017197

摘要： Physiological responses to low temperature were analyzed in a chilling-tolerant centipedegrass ( ) accession, Shao Guan (SG), in comparison to the commercial cultivar, Common. Lower levels of ion leakage and higher chlorophyll (Chl) concentration were observed in SG than in Common during chilling stress. The maximum photochemical efficiency, the actual photosystem II (PSII) efficiency, photochemical quenching efficiency, and net photosynthetic rate were decreased during chilling stress in both genotypes, with higher levels of these parameters shown by SG than Common. In addition, higher activities of superoxide dismutase (SOD), catalase (CAT), ascorbate-peroxidase (APX) and glutathione reductase (GR), and higher concentrations of ascorbic acid (AsA) and glutathione (GSH) were observed in SG than in Common. Moreover, higher concentrations of putrescine (Put), spermidine (Spd), and spermine (Spm) were observed in SG than in Common. Correlation analysis indicated that SOD, CAT, APX and GR activities, and AsA and GSH concentrations showed high correlation to Put, while APX, GR, and AsA concentrations were correlated to Spd. Exogenous Put or Spd increased antioxidant enzyme activities and chilling tolerance. The results suggested that polyamine-regulated antioxidants are important for chilling tolerance in centipedegrass and protect plants against chilling induced oxidative damage.

IN VITRO ACTIVITY OF EXTRACTS OF FIVE MEDICINAL PLANT SPECIES ON PLANT PATHOGENIC FUNGI

《农业科学与工程前沿（英文）》 2021年第8卷第4期页码 635-644 doi: 10.15302/J-FASE -2020343

摘要：

The antifungal effectiveness of extracts of five medicinal plant species was determined. The inhibitory activity of extracts of Eucalyptus tereticornis, Xanthium sibiricum, Artemisia argyi, Tupistra chinensis and Pyrola calliantha were evaluated against the mycelial growth of the plant pathogenic fungi Aspergillus niger, Botrytis cinerea, Penicillium digitatum, P. expansum, P. italicumand Rhizopus stolonifer. All plant extracts were prepared at 60°C using solvents (either water, 50% ethanol (v/v), 95% ethanol (v/v), ethyl acetate or petroleum ether). Fungicidal effects of all plants tested were confirmed. Different extracts from the same plant species gave different degrees of inhibition. All aqueous extracts had weak or no activity on all fungi tested. Ethyl acetate and 95% ethanol extracts from T. chinensis rhizomes gave greater inhibition and a broader spectrum inhibition than the other extracts. T. chinensis may have potential as a new natural fungicide and may be used for the preservation of agricultural and forestry products such as fruits and vegetables.

拟态防御技术结合软件多样化在软件安全产业中的应用

庞建民,张宇嘉,张铮、邬江兴

《中国工程科学》 2016年第18卷第6期页码 74-78 doi: 10.15302/J-SSCAE-2016.06.015

摘要：

随着互联网的飞速发展，计算机软件全球化的进程不断推进。大量相同软件安装在数以万计的计算机中，容易导致黑客利用软件的漏洞，攻击安装了该软件的所有计算机。传统的软件安全措施是依靠对漏洞进行修补，其只能起到亡羊补牢的作用。软件多样化技术可以使这种情况得到缓解，但其并没有从根本上消除漏洞带来的威胁。本文提出将拟态防御技术与软件多样化技术相结合应用于软件安全产业，可以消除漏洞带来的威胁。

基于多维动态网络属性的新型企业网防御系统的设计与实现 None

Yang CHEN, Hong-chao HU, Guo-zhen CHENG

《信息与电子工程前沿（英文）》 2019年第20卷第2期页码 238-252 doi: 10.1631/FITEE.1800516

摘要：虽然周界安全模型在内部主机可靠时足够有效，但是随着企业采用移动和云技术，如自带设备（BYOD），该模型难以为继。有针对性的高级网络攻击通常采用网络杀伤链，例如，基于网络扫描技术收集潜在目标信息。本文提出一种“隔离和动态”网络防御方法，切断潜在杀伤链，降低攻击者收集信息的可用性。首先，通过网络隔离构建一个零信任网络环境，操纵多维网络属性跳变，使攻击者无法获得目标主机的特征和位置；其次，为企业网络提出一种基于软件定义的主动网络防御解决方案（SPD），并设计了一个通用框架，在不显著影响网络性能条件下，策略性地操纵IP地址、网络端口、域名和路径的协同跳变；然后，通过软件定义网络控制器（OpenDaylight）实现SPD概念验证系统；最后，搭建实验平台验证系统防扫描、防窃听和防拒绝服务（DoS）攻击的能力。结果表明，该系统可以显著降低网络侦察扫描信息的可用性，阻止网络窃听，并大幅增加攻击者的网络攻击成本。
