METHODS:Nestin expression was detected in 33 cases of neuroepithelial tumors using the immunocytochemical staining. The Nestin positive and negative cells were isolated by magnetic activated cell sorting. Nestin positive cells were culutered, identified, and induced to differentiate. The expression of Nestin protein was detected in Nestin+ cells by RTPCR.

RESULTS: The neural stem cells isolated from neonatal rat brains had the potential of serial passage and proliferation, besides, they express neuroepithelial stem cell protein and differentiate into neurons, astrocytes and oligodendrocytes.

One Nitroso-bacteria named N1(GenBank registered number: EU647556) was isolated from the SBBR one-step completely nitrogen removal process, and was identified as Nitrosomonas sp. The characteristics of N1 were studied. Results showed that the optimal temperature and pH of N1 were 8.0 and 30℃respectively and sufficient dissolved oxygen was demanded.

N1(NCBI数据库中注册号为EU647556)，该菌株对氧气需求量存在较严格要求，pH及温度对其氨氧化活性具有明显的影响，最适条件分别为pH8.0和30℃，在氨氮浓度80～800mg/L较宽的底物浓度范围内具有活性，当氨氮浓度高达800mg/L时，其氨氧化活性没有受到明显的抑制。

So far, no sequence isolated from Nitzschia dosterium f. minutissima has been published in NCBI.

此外，小新月菱形藻的分类地位一直不是非常明确，有人认为它是三角褐指藻的另一种形式。

In order to discover acid-tolerant Rhizobium meliloti that can nodulate alfalfa high-effectively on acidic soil, researches were explored to isolate rhizobia from alfalfa nodules on acidic soil (pH5.2), methods based on the thesis of adaptive acid-tolerance response of the Rhizobia were adopted, six strains were isolated, which could grow on solid medium with pH4.8 steadily. In addition, the nodulation characteristics, growth curves and mean generation time under different acidity of the strains were examined.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
