    • Disclosed is a method of extracting all metabolites existing in a biological sample to detect a comprehensive difference between metabolites of a control group and a test group, thereby verifying significance thereof. More particularly, the invention comprises a first step of analyzing a fraction extracted with a solid phase extraction method, a fraction obtained by extracting the remnant fraction with a liquid-liquid extraction method and fractions extracted with the liquid-liquid extraction method at two pH different from each other after the hydrolysis, with a gas chromatography-mass spectrometry; a second step of converting the chromatogram result into numerical values capable of being statistically processed; and a third step of analyzing the numerical values with a principal component analysis (PCA) and a discriminant analysis (DA) to detect a difference between the control group and the test group. According to the invention, the difference between the two groups can be comprehensively detected with the areas of the peaks on the chromatogram, without a standard material or verified quantitative method. Therefore, it is possible to detect the metabolic change in the organism due to the disease or gene mutation, without an accurate quantitative analysis of the metabolites.
    • 公开了提取生物样品中存在的所有代谢物的方法,以检测对照组和试验组的代谢物之间的综合差异,从而验证其意义。 更具体地说,本发明包括分析用固相萃取法萃取的馏分的第一步骤,用液 - 液萃取方法提取剩余馏分获得的馏分,并用液 - 液萃取方法在两种pH值下提取馏分 水解后,用气相色谱 - 质谱联用; 将色谱图结果转换为能够进行统计处理的数值的第二步骤; 以及通过主成分分析(PCA)和判别式分析(DA)分析数值以检测对照组和测试组之间的差异的第三步骤。 根据本发明,可以用色谱图上峰的面积全面检测两组之间的差异,无需标准材料或经过验证的定量方法。 因此,可以检测由于疾病或基因突变而导致的生物体的代谢变化,而不对该代谢产物进行准确的定量分析。

    • Disclosed is a clock-based data storage device, which includes a dual pulse generating device and a data starge device having two dynamic nodes for prior chargement/dischargement. The clock-based data storage device includes a dual pulse generating unit which delays a clock signal and then outputs a first clock signal corresponding to inversion of a clock signal and a second clock signal corresponding to the clock signal by using the delayed clock signal when the clock signal shifts, a pull-up wait for outputting a pull-up output signal to an output port, based on the first clock signal outputted from the dual pulse generating unit and an input data signal which has beeb inputted, a pull-down unit for outputting a pull-down output signal to the output port, based on the second clock signal outputted from the dual pulse generating unit and the input data signal inputted which has been inputted, and a latch unit which is disposed between the pull-up and pull-down units, and the output port so as to store at least one output signal outputted f roars the pull-down unit as well as the pull-down unit.
