Trait-based community assembly analysis, which links the plant traits to the variation of community composition along environmental gradients, has potential to improve understanding of the impacts of
鄱阳湖部分湖区已经出现明显水华蓝藻聚集现象,并呈逐年加重的趋势.为探索鄱阳湖水华蓝藻的源头,对其水华蓝藻的现状及其影响因素进行分析.研究结果表明,鄱阳湖浮游植物的优势种为硅藻,蓝藻为鄱阳湖的次级优势种,并且蓝藻占浮游植物总生物量的比例有逐年增加的趋势.鱼腥藻为水华蓝藻的主要优势种,其次为微囊藻和浮游蓝丝藻.鄱阳湖水华蓝藻主要分布区域是营养盐浓度相对较高且水流较缓的内湾及尾闾区,仅在夏秋季水位较高时
Long-range anterograde transport of tropomyosin receptor kinase B (TrkB) in axons is important for exerting appropriate BDNF responses and plays a key role in neuronal survival, differentiation and sy
Oxidative stress affects diverse biological processes, including neuron homeostasis as well as cell survival and cell death.
Objective: toll-like receptors (TLRs) could mediate innate and adaptive immunity and also could be affected by oxidative stress.We previously had found that 17β-estradiol (E2) repressed the apoptosis
D-Ribose, an important reducing monosaccharide, is highly active in the glycation of proteins, and results in the rapid production of advanced glycation end products (AGEs) in vitro.
蛋白质的磷酸化和去磷酸化是一个动态可逆的过程,参与细胞内许多重要的生命活动,如细胞增殖、分化、迁移、凋亡等,而蛋白质的磷酸化和去磷酸化分别由激酶和磷酸酶来完成。过去很多年对激酶的研究非常重视和深入,近10多年来对磷酸酶的研究也越来越受到研究者的关注和重视。通过生物信息学的研究,我们发现了一种新的磷酸酶MIP,它是MTM家族成员的一种。
We have previously reported that five copies of the hypoxia response element (HRE) can conditionally regulate brain-derived neurotrophic factor gene expression under hypoxic/ischemic conditions in mic
Age-related cognitive impairment undergoes a continuous progression: from pre-mild cognitive impairment (preMCI) to mild cognitive impairment (MCI) and to Alzheimers disease (AD).
我们报道了人尿液细胞中可以分离出类上皮样的细胞，这类细胞能够被高效的诱导出多能干细胞及神经干细胞，为将来的再生医学研究提供了很好的来源。然而在实际工作中，我们发现尿细胞的组成具有多样性，而且批次之间的重编程差异比较大。另外，我们添加的几种小分子化合物如何导致神经干细胞命运的形成，尚不清楚。本研究中，我们利用单细胞分离技术，明确了尿液中细胞的种类及来源，并进一步研究了各种小分子化合物对于细胞重编程命
