By quantifying the diet composition of GAPs over crop stages, farm types and years, this study reveals that generalist predators have potential to produce a stable, predictable top‐down effect on pests in rice agro‐ecosystems. Therefore, promoting the field densities of ubiquitous generalist predators will likely enhance pest management and support ...

目的比较食管鳞癌患者和健康志愿者的血清代谢谱,寻找食管鳞癌特有的代谢标志物。方法选择一组明确诊断的食管鳞癌患者作为实验组、一组健康志愿者作为对照组,以液相色谱-质谱法(LC-MS)检测其血清轮廓代谢谱,通过单变量分析和多变量(主成分分析及偏最小二乘回归分析法等)比较两组代谢谱并寻找差异性代谢物,通过代谢物质通路的富集分析探讨其可能异常生物学过程。结果入组食管鳞癌患者20例为实验组,健康对照20例为对照组,变异倍数分析和T检验等单因素分析结果得出21种差异性代谢物(P<0.05);选择单变量分析P ...

Allelic Imbalance in Four Tumor Types [PDF]
肿瘤是人最主要的致死性疾病,其发生发展过程中均伴随着大量的基因组改变。当同源染色体片段相对于另一条同源染色体的拷贝数增加或减少时,伴随着一个现象的发生,等位基因不平衡。如果被扩增的同源染色体的片段携带着比另一条同源染色体更有利于肿瘤生长的遗传变异位点,则此片段在肿瘤细胞生长过程中有选择性优势。高通量测序技术的快速应用与精准医疗研究的快速发展,产生了海量基因组学数据,现在我们可以较容易且准确的获得整个基因组的完整信息。本研究从一个独特的视角来探究四种高发肿瘤(乳腺腺癌、结直肠腺癌、肺腺癌和前列腺癌 ...

基于生物信息学探讨合并心力衰竭的扩张型心肌病靶基因的预测 [PDF]
【目的】为了研究合并心力衰竭的扩张型心肌病发生发展相关的差异基因与调控信号通路,利用生物信息学方法探讨了基因表达汇编(GEO)中的基因芯片和人类基因和遗传疾病的在线目录(OMIM)中扩张型心肌病相关基因。【方法】本研究选择了由德国波鸿大学Herz-&DiabeteszentrumNRW实验室利用临床病例心肌活检标本在GPL570平台进行测序并上传至GEO公共数据库的两张芯片基因集:GSE29819和GSE21610。将合并心力衰竭的扩张型心肌病和正常心脏功能的心肌活检标本分别作为实验组 ...

Conservation benefits of a large marine protected area network that spans multiple ecosystems
Abstract Marine protected areas (MPAs) are widely implemented tools for long‐term ocean conservation and resource management. Assessments of MPA performance have largely focused on specific ecosystems individually and have rarely evaluated performance across multiple ecosystems either in an individual MPA or across an MPA network.

Adaptive Root of Mangrove Plant Avicennia marina: Structure and Transcriptome Analyses [PDF]
红树林泛指生长在热带、亚热带地区河口或海岸潮间带的木本植物群落,是适应陆地与海洋过渡区域的一种特殊森林类型。白骨壤(Avicenniamarina)是红树林中常见的红树植物,是群落演替中的先锋物种。对于生长在滨海湿地相对低氧环境的白骨壤而言,其根系统对湿地环境有高度专业化的适应。根据白骨壤根结构生长位置和生长方向不同,将其分为四种根结构,分别为在地面下方水平生长且围绕树干延伸数米的水平根(Cableroot)、垂直于水平根向地下生长的锚定根(Anchorroot ...

After the great Chinese poet Qu Yuan (屈原) was exiled to Xupu (溆浦) county in Hu' nan province, he described the forest there as follows: “mysterious is the deep forest, the place where Yuán yòu dwell (深林杳以冥冥兮,乃猿狖之所居).” What is the referent of the name Yuán yòu in this sentence?

Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions between plants and soil microorganisms in the rhizosphere are vital for maintaining the nutrient cycle and stability of terrestrial ecosystems. Nitrogen, closely related to carbon (C) cycling and ecosystem productivity, undergoes transformation by soil ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Many invasive plant species have demonstrated a better ability to tolerate and accumulate heavy metals than their co‐occurring native plants. Given the potential biological toxicity of heavy metals to phytopathogens, we postulated that heavy metal contamination could ...
