    • The invention provides transgenic, non-human animals and transgenic non-human mammalian cells harboring a transgene encoding a TGII (activator of the protein kinase cdk 5) polypeptide. The two neuropathological lesions associated with Alzheimer's disease (AD) are amyloid plaques and neurofibrillary tangles (NFTs), composed predominantly of amyloid β peptides and hyperphosphorylated tau, respectively. While animal models for plaque formation exist, there is no animal model that recapitulates the formation of NFTs. This invention provides transgenic mice that overexpress human TGII, an activator of cdk5, resulting in tau that is hyperphosphorylated at AD-relevant epitopes. Deposition of tau is detected in the amygdala, thalamus and cortex. Increased phosphorylated neurofilament, silver-positive neurons and neuronal death are also observed in these regions. We conclude that the overexpression of TGII, an activator of cdk5, is sufficient to produce hyperphosphorylation of tau and neuronal death. The TGII transgenic mouse represents the first model for tau pathology in AD.
    • 本发明提供具有编码TGII(蛋白激酶cdk 5的激活物)多肽的转基因的转基因非人动物和转基因非人哺乳动物细胞。 与阿尔茨海默氏病(AD)相关的两个神经病理学损伤分别是淀粉样蛋白斑和主要由淀粉样β肽组成的神经原纤维缠结(NFT)。 虽然存在斑块形成的动物模型,但没有重现NFT形成的动物模型。 本发明提供过表达人类TGII(cdk5的激活剂)的转基因小鼠,导致在AD相关表位上过度磷酸化的tau。 在杏仁核,丘脑和皮质中检测到tau的沉积。 在这些区域也观察到增加的磷酸化神经丝,银阳性神经元和神经元死亡。 我们得出结论,cdk5的激活剂TGII的过度表达足以产生tau和神经元死亡的过度磷酸化。 TGII转基因小鼠代表AD中第一个tau病理模型。

    • In large scale proteome applications, protein separation is paramount to observing discrete changes and quantitative evaluation must coincide with qualitative protein identification for effective differential analysis. A four dimensional (4D) platform for resolving and differentially analyzing complex biological samples is presented. The system, collectively termed CAX-PAGE/RPLC-MSMS, combines bi-phasic ion-exchange chromatography (1st dimension) and polyacrylamide gel electrophoresis (2nd dimension) for protein separation, quantification and differential band targeting leading toward subsequent capillary reverse phase liquid chromatography (3rd dimension) and data dependant tandem mass spectrometry (4th dimension) for semi-quantitative and qualitative peptide analysis.

    • Two reference signals are applied to an RC calibration circuit, which utilizes programmable resistors and switched capacitor resistors in parallel at the inputs of a differential amplifier with feedback capacitors, for the first cycle and then the two reference signals are swapped for the successive cycle. The circuit inherent DC offset is cancelled by these two successive cycles. The time duration when the difference of the differential amplifier outputs in the calibration circuit starts to reverse ramping direction and the time when the difference crosses zero is counted in terms of reference clock cycles by a binary counter. The binary count is used to select the capacitance of the capacitor arrays in an RC filter for time constant calibration. This calibration circuit provides the flexibility for various reference clock rates by adjusting the programmable resistors. By tuning the same programmable resistors, this calibration circuit in addition provides the capability to changing the cut-off frequency of an RC filter circuit to another predetermined value.
    • 两个参考信号被施加到RC校准电路,其在具有反馈电容器的差分放大器的输入端并联使用可编程电阻器和开关电容器电阻器,用于第一周期,然后两个参考信号被交换为连续循环。 电路固有的直流偏移由这两个连续的周期消除。 当校准电路中的差分放大器输出的差开始反向斜坡方向和差异跨越零的时间时,通过二进制计数器来计算参考时钟周期的持续时间。 二进制计数用于选择RC滤波器中电容器阵列的电容进行时间常数校准。 该校准电路通过调整可编程电阻器为各种参考时钟速率提供了灵活性。 通过调谐相同的可编程电阻器,该校准电路另外提供了将RC滤波器电路的截止频率改变到另一个预定值的能力。

    • A drive tray has a drive tray body with a retaining protrusion. A first lever arm is pivotally mounted on the drive tray body at a first lever arm first end and at a primary axis. The first lever arm has an open position and a closed position. The first lever arm also has a stopping protrusion. The first lever arm has a first lever arm length sufficient for providing a mechanical advantage to the stopping protrusion. The stopping protrusion protrudes away from a flat side of the drive tray for locking the drive tray to a case when in the first lever arm is in a closed position. The stopping protrusion retracts into a flat face of the drive tray when the first lever arm is in open position.
