| 1 | 发展中国家的可再生能源:沼气的机遇和挑战显示文摘能源对于现代社会至关重要,是社会经济发展最重要的指标之一。尽管科技不断发展,但仍然有约30亿人(主要集中在发展中国家的农村地区),继续通过在传统的炉灶中燃烧生物质资源(如柴薪、秸秆、动物粪便)的方式来满足烹饪的能源需求。这种方式对环境、社会、经济、公众健康都带来极大负面影响。这些地区要实现可持续性发展,开发干净清洁、价格低廉的可再生能源就势在必行。把现有的生物质资源(动物粪便、秸秆、餐厨垃圾、绿色废弃物)提炼成更加清洁高效的能源载体(例如厌氧发酵产生的沼气),不仅具有提供清洁、可靠能源的独特潜力,同时又能保护当地和全球的环境。尽管沼气对发展中国家来说意义重大,但其面临着成本高、设备安装和维护专业知识缺乏等问题,因而在地理位置分散的社区难以广泛推广应用。因此,政府和非政府层面的通力协作就显得至关重要,从而促进沼气技术的更新改造和传播,开发尚未被开发的潜力。文章旨在通过分析沼气技术的现状、挑战和潜力,明确它在发展中国家未来的研究方向和发展传播路径。 | K C Surendra Devin Takara rew G Hashimoto Samir Kumar Khanal 李谦 | 2015 | 中国沼气2015，33，1： | 3 |

| 6 | Expression analysis of reactive oxygen species detoxifying enzyme genes in Anopheles stephensi during Plasmodium berghei midgut invasion显示文摘Objective:To investigate the involvement of reactive oxygen species detoxification system in Anopheles stephensi during Plasmodium berghei midgut invasion.Methods:Eight key reactive oxygen species metabolizing enzymes were cloned and characterized,and their expression was monitored in parasite-infected mosquitoes.Results:Superoxide anion detoxifying superoxide dismutases(Fe/Mn SOD,Cu/Zn SOD 2,Cu/Zn SOD 3A,and Cu/Zn SOD 3B)depicted varied expression patterns.Fe/Mn SOD expression declined,whereas Cu/Zn SOD expression was elevated in the infected mosquitoes.Peroxidases,catalase and glutathione peroxidase showed lack of induction in expression during the Plasmodium berghei infection.Further,expression of thioredoxin reductase increased in the infected mosquitoes,whereas gluthathione S-transferase levels decreased markedly.Conclusions:Detoxification enzymes may play a role in modulating host immunity and parasite transmission. | RK Chaitanya P Sridevi K Surendra Kumar Babu S Mastan K Arun Kumar A Dutta-Gupta | 2014 | Asian Pacific Journal of Tropical Medicine2014，7，9： | 0 |
