This paper provides the experience of applying an advanced version of our former spurious power suppression technique (SPST) on multipliers for high-speed and low-power purposes. To filter out the useless switching power, there are two approaches, i.e., using registers and using AND gates, to assert the data signals of multipliers after the data transition.(More)
This paper proposes a high-performance low-power direct 2-D transform coding IP design for H.264 with a switching power suppression technique. The proposed transform coding design not only suitably arranges the data sequences in row and column transforms to greatly increase the data processing rate but also takes advantage of the correlation existed in(More)
Tangeretin (5,6,7,8,4'-pentamethoxyflavone) is a polymethoxylated flavonoid concentrated in the peel of citrus fruits. Recent studies have shown that tangeretin exhibits anti-proliferative, anti-invasive, anti-metastatic, and antioxidant activities. However, the anti-inflammatory properties of tangeretin are unclear. In this study, we examine the effects of(More)
A significant loss of neurons in the dorsal root ganglia (DRG) has been reported in animal models of peripheral nerve injury. Neonatal sensory neurons are more susceptible than adult neurons to axotomy- or nerve growth factor (NGF) withdrawal-induced cell death. To develop therapies for preventing irreversible sensory cell loss, it is essential to(More)
In this paper, a CMOS cascaded two-stage distributed amplifier for ultra-wideband (UWB) application is presented. The circuit using two-stage cascaded topology achieves better gain-bandwidth product performance than conventional CMOS distributed amplifiers. The simulated gain is 18dB with /spl plusmn/1dB gain flatness over 3.1/spl sim/10.6 GHz bands. Input(More)
BACKGROUND In this study, we tested the hypothesis that a combined adipose-derived mesenchymal stem cell (ADMSC) and ADMSC-derived exosome therapy protected rat kidney from acute ischemia-reperfusion (IR) injury (i.e., ligation of both renal arteries for 1h and reperfusion for 72h prior to euthanization). METHODS AND RESULTS Adult-male SD rats (n=40) were(More)
