    • This disclosure generally relates to components and methods of using a high throughput screening (HTS) systems for intracellular proteases, using Caspases as a prototype. Genetic systems are disclosed for monitoring exogenous caspase activation pathways in the yeast, Saccharomyces cerevisiae. The yeast-based cellular systems permit facile expression of proteases (e.g., caspase) and protease-activating proteins in combinations that reconstitute entire mammalian pathways in these simple eukaryotes. Among the assay methods integrated into the yeast system are cleavable reporter gene activators, in which protease-mediated cleavage activates a transcription factor. Exemplary systems rely, singly or in concert, on exogenous recombinant caspases and exogenous upstream activators of caspases to cleave a chimeric protein giving rise to a transcription factor which induces the expression of the LacZ and LEU2 genes. The activities of these genes result in colored cultures and impart the ability of the yeast to grow in leucine deficient media. The intensity of the color is measured by colorimetry and quantified with OD units. The OD units are directly proportional to the activity of the caspase in the system. The method of quantification is referred to as the “readout”.
    • 本公开通常涉及使用胱天蛋白酶作为原型的细胞内蛋白酶的高通量筛选(HTS)系统的组件和方法。 公开了用于监测酵母,酿酒酵母中的外源半胱天冬酶活化途径的遗传系统。 基于酵母的细胞系统允许在这些简单真核生物中重组整个哺乳动物途径的组合,容易地表达蛋白酶(例如胱天蛋白酶)和蛋白酶活化蛋白。 整合到酵母系统中的测定方法中是可裂解的报告基因激活因子,其中蛋白酶介导的切割激活转录因子。 示例性系统单独或一致地依赖于外源重组胱天蛋白酶和胱天蛋白酶的外源上游激活剂以切割嵌合蛋白,产生诱导LacZ和LEU2基因表达的转录因子。 这些基因的活性导致有色培养物,并赋予酵母在亮氨酸缺乏培养基中生长的能力。 通过比色法测量颜色的强度并用OD单位定量。 OD单位与系统中半胱天冬酶的活性成正比。 定量方法被称为“读出”。

    • A current detection unit detects an electric current caused by superimposing a direct current from a direct-current power source on an alternating current from an alternating-current power source and supplied through a brush to a direct-current motor. An extracting unit extracts an alternating-current component of the detected electric current. An angle detection unit detects a rotation angle of the motor according to the extracted alternating-current component. A direction detection unit detects a rotative direction of the motor according to a change pattern of the extracted alternating-current component. A core of the motor has slots each defined between adjacent two of teeth. The slots respectively accommodate phase coils respectively wound around the teeth. Turns of the phase coils are different from each other.
