Exploring effective drugs that are capable of promoting nerve regeneration has gained much attention. Ginsenoside Re (Re) is the main ingredient of ginseng berries and roots. Research in the area has shown that ginsenoside Re exhibits multiple pharmacological activities via different mechanisms both in vivo and in vitro. But the potential therapeutic(More)
—In recent years, the security issues of the cognitive radio (CR) networks have drawn a lot of research attentions. Primary user emulation attack (PUEA), as one of common attacks, compromises the spectrum sensing, where a malicious user forestalls vacant channels by impersonating the primary user to prevent other secondary users from accessing the idle(More)
—This paper proposes to use a cognitive-relay technique to mitigate intercell interference (ICI) in cellular systems. In the proposed system, several relay stations (RSs) that are equipped with cognitive radio are deployed near the cell boundary. The base station (BS) and the RS in each cell operate in the same spectrum band as primary and secondary(More)
—With the requirement of average end-to-end bit error rate (BER) performance, we study power-adaptation problems for multihop ad hoc networks to minimize the power consumption in fading channels, considering two scenarios with regard to the knowledge of the channel-state information (CSI). One is that the transmitter for each hop knows the instantaneous CSI(More)
LIN28, an RNA-binding protein, is known to be involved in the regulation of many cellular processes, such as embryonic stem cell proliferation, cell fate succession, developmental timing, and oncogenesis. However, its expression and function in central nervous system still unclear. In this study, we performed an acute spinal cord contusion injury (SCI)(More)
To investigate the expression of Sam68 in articular cartilage of knee osteoarthritis (OA) and the relationship between Sam68 and NF-κB activation and apoptosis signaling in OA articular chondrocytes. Sam68 expression in normal and osteoarthritic cartilage was assessed by immunohistochemistry and RT-PCR on both meniscal/ligamentous injury (MLI)-induced OA(More)
