The link quality variation of wireless channels has been a challenging issue in data communications until recent explicit exploration in utilizing this characteristic. The same broadcast transmission may be perceived significantly differently, and usually independently, by receivers at different geographic locations. Furthermore, even the same stationary(More)
When incorporating machine-to-machine (M2M) communications into the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) networks, one of the challenges is the traffic overload since many machine-type communication (MTC) devices activated in a short period of time may require access to an evolved node B (eNodeB) simultaneously. One approach(More)
Opportunistic data forwarding has drawn much attention in the research community of multihop wireless networking, with most research conducted for stationary wireless networks. One of the reasons why opportunistic data forwarding has not been widely utilized in mobile ad hoc networks (MANETs) is the lack of an efficient lightweight proactive routing scheme(More)
OBJECTIVE MicroRNAs (miRNAs) are non-coding, single-stranded small RNAs that regulate gene expression negatively, which is involved in fundamental cellular processes and the initiation, development and progression of human cancer. In this study, we investigated the role of miR-27a in the development of drug resistance in ovarian cancer cells. METHODS(More)
Cancer-associated fibroblasts (CAFs) are thought to play an essential role in cancer initiation and development. However, little research has been done to evaluate the role of CAFs in epithelial ovarian cancer (EOC) development. To address this issue, ninety-one specimens were immunostained with α-smooth muscle actin (α-SMA) and fibroblast activation(More)
The current wireless cellular networks can be used to provide machine-to-machine (M2M) communication services. However, the Long Term Evolution (LTE) networks, which are designed for human users, may not be able to handle a large number of bursty random access requests from machine-type communication (MTC) devices. In this paper, we propose a scheme that(More)
Enhancer of Zeste Homologue 2 (EZH2), a specific histone 3 lysine 27 (H3K27) methyltransferase, plays a critical role in tumorigenesis and cancer progression through epigenetic gene silencing and chromatin remodeling. However, the role of EZH2 in chemotherapy resistance is unknown. In this study, we found that EZH2 was overexpressed in cisplatin-resistant(More)
OBJECTIVE To examine the expression of PDGF and its receptors in leiomyoma tissue and to investigate the regulation of PDGF on leiomyoma cell proliferation. MATERIALS AND METHODS The expression of PDGF and its receptors was examined in 21 pairs of uterine leiomyoma and the adjacent myometrium tissues using an immunostaining method. Paired cultures of(More)
OBJECTIVE Individuals with Fanconi anemia (FA) are predisposed to develop ovarian cancer than those without FA, this is largely contributed to promoter methylation of the FANCF gene and subsequent disruption of the FA-BRCA pathway. In an attempt to understand more molecular genetic bases of ovarian cancer, we examined the expression of the FANCF and the(More)
OBJECTIVE The purpose of this study was to investigate the role of miR-130b in the development of multidrug-resistant ovarian cancer. METHODS The expression of miR-130b was assessed in ovarian tissues and cell lines by qRT-PCR. In vitro, miR-130b level was manipulated by transfection with mimics or inhibitors. Methylation level of miR-130b was evaluated(More)
