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)
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 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 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)
The lack of access to fast Internet services is a serious digital divide for future networks. Most areas outside fast Internet service coverage are rural areas. Many kinds of wireless systems have been proposed for rural areas because of their low establishment cost per residence. Where there are several residences in a small area, a wireless system is(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)
