Recent studies indicate that insulin resistance resulting from altered post-receptor signaling is associated with polycystic ovary syndrome (PCOS). We hypothesized that insulin receptor substrate-1 (IRS-1) Gly972Arg polymorphism and/or ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) Lys121Gln polymorphism predisposes women to PCOS and that these(More)
BACKGROUND Vaginal radical trachectomy (RT) ligates and cuts several arteries supplying the uterus. Changes of blood supply to the uterus in two patients who experienced pregnancy and delivery were studied by using 3-D CT scanning. Effects of changes of blood supply to the uterus on the pregnancy courses were also examined. METHODS Vascular distribution(More)
Gap-junction plaques are often observed with tight-junction strands of vascular endothelial cells but the molecular interaction and functional relationships between these two junctions remain obscure. We herein show that gap-junction proteins connexin40 (Cx40) and Cx43 are colocalized and coprecipitated with tight-junction molecules occludin, claudin-5, and(More)
BACKGROUND An approach consisting of elective cryopreservation of all embryos has been proposed for patients at risk of ovarian hyperstimulation syndrome (OHSS). Although elective cryopreservation can prevent pregnancy-induced late OHSS, it cannot prevent early OHSS. Early OHSS is reported to have been complicated with thromboembolism. The study was carried(More)
OBJECTIVE To report a rare case of spontaneous ovarian hyperstimulation syndrome (OHSS) associated with spontaneous pregnancy and a FSH-secreting pituitary adenoma. DESIGN Case report. SETTING University hospital. PATIENT(S) A 32-year-old woman with spontaneous OHSS. INTERVENTION(S) Transsphenoidal resection of the tumor. MAIN OUTCOME MEASURE(S)(More)
We have performed 36 vaginal radical trachelectomies (RTs) for patients with early invasive uterine cervical cancer and experienced 10 deliveries. Pregnancy after RT has far higher risks of prematurity and complications such as preterm premature rupture of the membrane (pPROM) and chorioamnionitis. We report the significance of transabdominal cerclage in(More)
Treatment of placenta increta often entails abdominal total hysterectomy. We present a case of placenta increta in which 3-dimensional computed tomography shows very high blood flow to the placenta, even after chemotherapy with methotrexate. Nonetheless, we were able to remove the region of the uterus that had been invaded by chorionic villi. Massive(More)
Single-incision laparoscopic surgery (SILS) has been quickly accepted, especially for women, because the cosmetic benefits may be greater than with ordinary laparoscopic surgery. In gynecologic disease, SILS is appropriate for diagnostic laparoscopy, oophorectomy, and salpingectomy, among other conditions. In addition, the knot-tying process for(More)
One of the characteristics of polycystic ovary syndrome (PCOS) is the presence of cystic follicles in various stages of growth and atresia, the latter of which is known to be the result of apoptosis and tissue remodeling. To further investigate the process of follicular atresia, we compared ovarian expression and localization of Fas, Fas ligand (FasL),(More)
