摘要:

By measuring the quantity and ways in which antimicrobials are used, and reviewing different technical and socioeconomic factors influencing antimicrobial use at farm level, this study discusses the main knowledge gaps in antimicrobial use in food animal production and provides recommendations for future research and policy development. The review reveals that antimicrobial use in food animals exhibit strong regional and species differences, and there are still large information gaps concerning the current state of antimicrobial use. Factors associated with animal health (including antimicrobial resistance), animal health improvement, economic costs and benefits relevant to animal diseases, and potential technological alternatives or alternative systems all have an impact on antimicrobial use on the farm. There is a clear need to resolve the data gap by monitoring antimicrobial use and developing an analytical framework to better understand farmer behaviors under different technical, economic and environmental circumstances.

《医学前沿(英文)》 2016年 第10卷 第4期   页码 517-521 doi: 10.1007/s11684-016-0480-9

摘要:

This study aimed to compare the antimicrobial activities of topical agents against Propionibacterium acnes isolated from patients admitted to a hospital in Shanghai, China. The minimal inhibitory concentrations of the cultured P. acnes were determined in accordance with the Clinical and Laboratory Standards Institute. Susceptibilities to clindamycin and erythromycin were compared in terms of gender, age, disease duration, previous treatment, and disease severity. A total of 69 P. acnes strains were isolated from 98 patients (70.41%). The susceptibility to triple antibiotic ointment (neomycin/bacitracin/polymyxin B) and bacitracin was 100%. The susceptibility to fusidic acid was 92.7%. The resistance rates to neomycin sulfate, erythromycin, and clindamycin were 11.7%, 49.3%, and 33.4%, respectively. The high resistance rate to clindamycin and erythromycin was significantly affected by gender, previous treatment, and disease severity rather than by age and disease duration. Topical antibiotics should not be used separately for long-term therapy to avoid multiresistance. The use of topical antibiotics should be determined by clinicians on the basis of clinical conditions.

摘要:

新冠病毒肺炎疫情的大流行,使得抗菌纺织品的重要性以及人们对其需求达到了新的高度。除了医疗目的,抗菌纺织品还可以成为普通人对抗微生物的自我防御实体。抗菌纺织品可以有效地防止微生物在全世界的传播。纺织品的传统抗菌整理工艺采用的是湿式处理方法,即采用填充—干燥—固化或排气技术。但纺织品湿处理行业是世界范围内引起环境污染的主要原因之一,这一点令人极为担忧。鉴于目前和近期的高需求,将等离子体纳入抗菌整理工艺,以实现高效率的生产,同时保持一个安全的环境,是当务之急。因此,本文通过对近期研究的批判性分析,回顾了等离子体在纺织品抗菌整理技术中的应用原理,并强调了用于实际应用的等离子体技术的类型和机制。

摘要:

副猪嗜血杆菌是一种对全球养猪业造成重大经济损失的病原菌。副猪嗜血杆菌防控失败的原因之一是细菌耐药性不断加重。越南拥有亚洲排名第二的生猪产量,但是缺乏针对副猪嗜血杆菌耐药性的相关研究和数据。本研究的目的是调查越南副猪嗜血杆菌的耐药性,并分析耐药性和耐药性基因之间的关系。本研究所使用的副猪嗜血杆菌分离菌株来自我们之前研究中从越南广平省和顺化省猪场分离到的菌株。本研究分别利用肉汤微稀释法和聚合酶链反应(PCR)法检测了这些菌株对25种抗生素的耐药性及相关耐药基因的存在情况。结果显示,这些分离株对甲氧苄啶/磺胺甲恶唑的耐药率达高到94.6%,其次是黏菌素、氯霉素、庆大霉素、青霉素、林可霉素和阿莫西林。这些菌株中相关联耐药基因的检出率分别为blaTEM-1 94.6%、int 76.8%、gyrA 58.9%以及rmtD 50.0%。头孢呋辛、氯霉素和妥布霉素的耐药性表型分别与耐药基因blaROB-1 [优势比(OR) = 26.3, 95% 置信区间(CI)2.7~255.7, p = 0.002]、catl (OR = 25.1, 95% CI 2.4~258.9, p = 0.004)以及strB (OR = 23.5, 95% CI 2.6~212.6, p = 0.001)呈显著正相关。本研究首次揭示了越南中部地区副猪嗜血杆菌的耐药性情况,有助于该疾病的临床控制,能够为降低越南中部的养猪业中该菌的耐药性以及为相关政策制定和临床用药提供指导。

Moving policy and regulation forward for single-use plastic alternatives

《环境科学与工程前沿(英文)》 2021年 第15卷 第3期 doi: 10.1007/s11783-021-1423-5

摘要: Single-use plastics are often used once or cannot be reused for extended periods. They are widely consumed with the rapid development of social economy. The waste generated by single-use plastics threatens ecosystem health by entering the environment and ultimately restricts sustainable human development. The innovation of sustainable and environmentally friendly single-use plastic alternative materials and the joint participation of governments, enterprises and the public are promising technologies and management approaches that can solve the problem of single-use plastics wastes. The development of single-use plastic alternative products can be promoted fundamentally only by improving relevant legislation and standards, providing differentiated industrial policies, encouraging scientific and technological innovation and expanding public participation.

Strategies on designing multifunctional surfaces to prevent biofilm formation? ?

Yang Lu,Zhanguo Yue,Wei Wang,Zhiqiang Cao

《化学科学与工程前沿(英文)》 2015年 第9卷 第3期   页码 324-335 doi: 10.1007/s11705-015-1529-z

摘要: Bacteria adhesion and biofilm formation have raised severe problems on public health, food industry and many other areas. A variety of reagents and surface coatings have been developed to kill bacteria and/or limit their interaction with surfaces. It has also attracted many efforts to integrate different bactericidal elements together and maximize antibacterial efficiency. Herein, we review mechanisms for both passive and active approaches to resist and kill bacteria respectively, and discuss integrated strategies based on these two approaches. We also offer perspective on future research direction.

Approaches to achieve high grain yield and high resource use efficiency in rice

《农业科学与工程前沿(英文)》 2015年 第2卷 第2期   页码 115-123 doi: 10.15302/J-FASE-2015055

摘要: This article discusses approaches to simultaneously increase grain yield and resource use efficiency in rice. Breeding nitrogen efficient cultivars without sacrificing rice yield potential, improving grain fill in later-flowering inferior spikelets and enhancing harvest index are three important approaches to achieving the dual goal of high grain yield and high resource use efficiency. Deeper root distribution and higher leaf photosynthetic N use efficiency at lower N rates could be used as selection criteria to develop N-efficient cultivars. Enhancing sink activity through increasing sugar-spikelet ratio at the heading time and enhancing the conversion efficiency from sucrose to starch though increasing the ratio of abscisic acid to ethylene in grains during grain fill could effectively improve grain fill in inferior spikelets. Several practices, such as post-anthesis controlled soil drying, an alternate wetting and moderate soil drying regime during the whole growing season, and non-flooded straw mulching cultivation, could substantially increase grain yield and water use efficiency, mainly via enhanced remobilization of stored carbon from vegetative tissues to grains and improved harvest index. Further research is needed to understand synergistic interaction between water and N on crop and soil and the mechanism underlying high resource use efficiency in high-yielding rice.

摘要:

多重耐药菌的出现迫切需要发现具有新作用机制的抗生素。在本研究中,笔者将疏水的吖啶分子连接到核定位序列 (NLS) 的N末端合成了一种新型的抗菌药物Acr3-NLS。为了进 一步提高该试剂的抗菌活性,笔者将两个单体Acr3-NLS分子通过二硫键连接合成了二聚体(Acr3-NLS)2。结果显示,与NLS相比,Acr3-NLS,特别是(Acr3-NLS)2,对革兰阴性菌和革兰阳性菌表现出显著的抗菌活性。随后,其作用机制的研究表明,Acr3-NLS 和(Acr3-NLS)2 可通过细胞膜破坏方式和DNA 结合方式杀死细菌。作用于细胞膜和细胞内DNA的双靶点抑杀机制可以降低细菌对Acr3-NLS 和(Acr3-NLS)2 产生耐药性的风险。总之, 本研究提供了一种新的策略,可用于设计具有双重作用机制的高效抗菌药物。

WATER USE IN HUMAN CIVILIZATIONS: AN INTERDISCIPLINARY ANALYSIS OF A PERPETUAL SOCIAL-ECOLOGICAL CHALLENGE

《农业科学与工程前沿(英文)》 2021年 第8卷 第4期   页码 512-524 doi: 10.15302/J-FASE -2021393

摘要:

Settlement patterns and social structures have been shaped by access to water since the onset of human societies. This review covers historical and recent examples from Cambodia, Central Asia, India, Latin America and the Arabian Peninsula to analyze the role of water resources in determining the rise and collapse of civilizations. Over recent decades increasing globalization and concomitant possibilities to externalize water needs as virtual water have obscured global dependence on water resources via telecoupling, but rapid urbanization brings it now back to the political agenda. It is foremost in the urban arena of poorer countries where competing claims for water increasingly lead to scale-transcendent conflicts about ecosystem services. Solutions to the dilemma will require broad stakeholder-based agreements on water use taking into account the available data on water resources, their current and potential use efficiency, recycling of water after effective treatment, and social-ecological approaches of improved governance and conflict resolution.
