Notch-mTOR信号介导的免疫反应与能量代谢轴:中医药预防IBD复发的可能关键

open access: yes, 2016
炎症性肠病(inflammatory bowel disease,IBD)是世界性难治性疾病,其难治在于高复发率.中医药治疗IBD疗效高且复发率低,但作用机制不明,然Notch与mTOR信号间相互关联,且通过各种途径调控机体免疫水平和细胞能量代谢变化,并与IBD的发作密切相关,提示调控Notch-mTOR信号介导免疫与能量轴变化可能是探索中医药预防和防止IBD复发的可能突破口和有效策略.

Production of 1,3-Propanediol from Raw Glycerol by Biocatalytic Transformation [PDF]

open access: yes, 2013
1,3-丙二醇(1,3-PD)是一种重要的化工原料,具有广泛的应用领域。发酵法生产1,3-PD以利用可再生资源等优点日益受到重视。大部分研究以纯甘油为底物,成本高,如果以粗甘油为底物,可大大降低生产成本。 本论文的研究目的是以粗甘油为底物,以Clostridiumbutyricum(丁酸梭状芽孢杆菌)为生产菌株,通过厌氧发酵生产1,3-PD,在粗甘油预处理、提高菌体浓度、提高单位菌体生产能力、延长发酵周期和建立动力学模型这几个方面进行了研究,主要结果如下: (1 ...

Fat storage and drought tolerance in a seasonally‐adapted primate: Implications for modeling the effects of animal responses to global climate change 灵长类动物在季节性适应下的脂肪储存和耐旱性:模拟动物应对全球气候变化影响的启示

open access: yesIntegrative Conservation, Volume 3, Issue 3, Page 168-182, September 2024.
Using long‐term field data, we examined the impact of severe droughts on the health, reproductive success, and behavior of the critically endangered Verreaux's sifaka (Propithecus verreauxi) in Madagascar's seasonally dry tropical forest. Despite reduced availability of high‐quality foods, sifaka exhibited stable body condition and reproductive success,

Gut microbiota dynamics of adult and sub‐adult sika deer during reintroduction 重引入过程中成年和亚成年梅花鹿肠道微生物的动态变化

open access: yesIntegrative Conservation, Volume 3, Issue 3, Page 257-270, September 2024.
Natural training enclosure design schematic. We selected 12 sika deer including six adults and six sub‐adults. Key considerations in the design of the natural training were to divide the training spatial ground into two parts (30 × 30 m small areas for isolation of new individuals and large areas measuring 200 × 600 m for free walking), and the ...

Metaproteomic study of marine phytoplankton blooms [PDF]

open access: yes, 2015
浮游植物是海洋初级生产力的主要贡献者,也是海洋食物链的重要组成,在海洋碳循环、生态系统维持和全球气候调节中起着重要作用。浮游植物藻华,特别是高频发生的甲藻和硅藻藻华,深刻地影响着海洋生态系统、全球气候以及人类健康。目前在浮游植物藻华形成的生态学和海洋学机制方面开展了大量工作,但我们对藻华形成的分子机制知之甚少。 本论文将宏蛋白质组学理念和方法应用于海洋浮游植物藻华研究,结合生物信息学分析手段,建立了海洋浮游植物藻华宏蛋白质组学研究方法,比较研究了藻华爆发区与非藻华区 ...
