This paper proposes Inter PAN mobility support for 6LoWPANs moving within an IP domain. In order to reduce the processing and signaling load on the mobile node (MN) caused by the movement, the mobility related processing of 6LoWPAN nodes is delegated to the existing PAN entities with less power constraints. Also this mobility support mechanism aims to(More)
Anticancer activity of silibinin, a flavonoid, has been demonstrated in various cancer cell types. However, the underlying mechanisms were not elucidated in human ovarian cancer cells. The present study was undertaken to examine the effect of silibinin in vitro and in vivo on tumor growth in human ovarian cancer cells. Silibinin decreased cell viability in(More)
The liver is covered by visceral peritoneum except at the bare area, bed of the gallbladder, and porta hepatis. The investing peritoneum becomes contiguous with the adjacent structures such as the diaphragmatic peritoneum, lesser omentum, and ligamentum teres. An inflammatory process or tumors involving the perihepatic space are usually affected by(More)
BACKGROUND Silibinin, a natural polyphenolic flavonoid, has been reported to induce cell death in various cancer cell types. However, the molecular mechanism is not clearly defined. Our previous study showed that silibinin induces glioma cell death and its effect was effectively prevented by calpain inhibitor. The present study was therefore undertaken to(More)
OBJECTIVE To measure the prognostic value of the lymphocyte-monocyte ratio (LMR) in patients with epithelial ovarian cancer (EOC). METHODS We retrospectively examined the LMR as a prognosticator in a cohort of 234 patients with EOC who underwent surgical resection. Patients were categorized into two different groups based on the LMR (LMR-low and LMR-high)(More)
OBJECTIVES Test of human papillomavirus (HPV) is a useful adjunctive tool of Pap smear to screen cervical cancer. We have developed a novel HPV genotyping DNA chip arrayed by multiple oligonucleotide probes of both L1 and E6/E7 gene sequence of 42 types of anogenital HPV. METHODS Consensus PCR products of L1 and E6/E7 gene sequences of HPV are hybridized(More)
OBJECTIVE To investigate the relationship between follicular blood flow and the follicular fluid vascular endothelial growth factor (VEGF) and nitric oxide (NO) concentrations and to determine which factor might be a better predictor of the outcome of IVF-ET. DESIGN Prospective study. SETTING Academic research laboratory. PATIENT(S) Forty-seven cycles(More)
The flavonoid, luteolin, has been shown to have anticancer activity in various cancer cells; however, the precise molecular mechanism of its action is not completely understood, and studies were conducted to find out how it induces apoptosis in breast cancer cells. Luteolin induced a reduction of viability in a dose- and time-dependent manner. The(More)
OBJECTIVE To investigate the effects of nitric oxide on endometrial cell proliferation and the effects of peritoneal fluid from women with and without endometriosis on the production of nitric oxide and upon the nature of nitric oxide-induced changes. STUDY DESIGN Ovarian endometriotic and endometrial stromal cells and peritoneal fluid were obtained from(More)
BACKGROUND Resistance to apoptosis is 1 of the key events that confer chemoresistance and is mediated by the overexpression of antiapoptotic proteins, which inhibit caspase activation. The objective of this study was to evaluate whether the activation of an alternative, caspase-independent cell death pathway could promote death in chemoresistant ovarian(More)
