Genome-wide association studies (GWAS) have reported a number of loci harboring common variants that influence risk of colorectal cancer (CRC) in European descent. But all the SNPs identified explained a small fraction of total heritability. To identify more genetic factors that modify the risk of CRC, especially Chinese Han specific, we conducted a(More)
Dielectrophoresis (DEP) can be used to noninvasively measure the dielectric state of the cell, and this data can be used to monitor cell health or apoptosis. In this study, we followed events associated with cytosine arabinoside (Ara-C)-induced apoptosis in NB4 cells using DEP analysis. Our data showed that the membrane capacitance of NB4 cells decreases(More)

As a driving device, the DC-motor makes the steering wheel tum left or right above 3 rounds respectively. When the DSP regulator receives an instruction from the computer, it can make the DC-motor tum quickly and can transmit data which includes the angle and the angular velocity to the computer. Some main components of the HILSTP are shown as Fig.2 and(More)
