We investigated the relationship between oxidative stress and poor oocyte quality and whether the antioxidant melatonin improves oocyte quality. Follicular fluid was sampled at oocyte retrieval during in vitro fertilization and embryo transfer (IVF-ET). Intrafollicular concentrations of 8-hydroxy-2'-deoxyguanosine (8-OHdG) in women with high rates of(More)
BACKGROUND Clomiphene citrate (CC) is most commonly used as a first-line treatment of infertility. However, a disturbance of endometrial growth by the adverse effects of the CC has been recognized. Since a thin endometrium is recognized as a critical factor of implantation failure, preventing CC-induced thinning of the endometrium is important. This study(More)
A home-network is expected to spread now. We considered the security issues on home networks based on power line communication, because these topics have not been sufficiently considered. We discuss the issues, risk and required countermeasures. These issues are categorized into control network, information network, AV network and community network. We also(More)
BACKGROUND Blood flow in the corpus luteum (CL) is associated with luteal function. The present study was undertaken to investigate whether luteal function can be improved by increasing CL blood flow in women with luteal phase defect (LFD). METHODS Blood flow impedance in the CL was measured by transvaginal color-pulsed-Doppler-ultrasonography and was(More)
MIS (mobile Internet services) architecture is designed for secure connection and fast handover with wireless LAN. This architecture consists of three protocols, MISP (mobile Internet services protocol), MISAUTHP (mobile Internet services authentication protocol) and MIS MobilelP, and two kinds of servers, authentication servers and home agent, base routers(More)
A loss of the DNA copy number at chromosomal region 11q23-24 as detected by comparative genomic hybridization (CGH) is a marker of poor prognosis in patients with endometrial cancer. Malignant tumors display genetic instability, which is classified into two types: microsatellite instability (MIN) and chromosomal instability (CIN). In the present study, we(More)
In the event of a disaster, communication networks including telephone, cell phone, and CATV may stop these services due to the damages caused by the disaster such as earthquake and typhoon. Even in that case, we should maintain communication lines to share the information of sufferers and to grasp the situation of the damaged-area, e.g. line disconnection(More)
—We designed and implemented seamless handover on wireless LAN with MISP (Mobile Internet Services Protocol), PDMA (Packet Division Multiple Access) and mobile IP. MISP is a protocol designed for mutual authentication, IP address assignments, session key sharing and various negotiations between mobile nodes and access points with a single exchange of(More)
BACKGROUND Blood flow in the corpus luteum (CL) is closely related to luteal function. It is unclear how luteal blood flow is regulated. Standardized ovarian-stimulation protocol with a gonadotropin-releasing hormone agonist (GnRHa long protocol) causes luteal phase defect because it drastically suppresses serum LH levels. Examining luteal blood flow in the(More)
