Mucosal T cells are essential to immune tolerance in the intestine, an organ constantly exposed to large amounts of dietary and bacterial Ags. We investigated whether local fibroblasts affect mucosal T cell survival, which is critical for maintenance of immune tolerance. Coculture with autologous fibroblasts significantly increased viability of mucosal T(More)
The aim of this study was to quantitate of vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), and angiogenin in follicular fluid (FF) and to correlate the levels of these substances with oocyte maturation. FF were aspirated from women undergoing in vitro fertilization and embryo transfer. Sera were collected from women with normal(More)

BACKGROUND Women with polycystic ovary syndrome (PCOS) are generally insulin- resistant and are consequently often treated with metformin. We investigated the effect of metformin and AICAR on the AMP-activated protein kinase (AMPK) pathway. METHODS We evaluated the effects of 5-amino-imidazole-4-carboxyamide-1- beta-D-ribofuranoside (AICAR) and metformin(More)
The incidence of ectopic pregnancy is approximately 1.3-2% of all pregnancies, and more than 90% of ectopic pregnancies are detected in the ampulla of the fallopian tube. Ectopic pregnancy occurring in tubal stump after tubectomy is extremely rare, and the frequency of tubal stump pregnancy is approximately 0.4% of all pregnancies. We report one of these(More)
Mayer-Rokitanski-Kuster-Hauser (MRKH) syndrome is a rare disease. A 27-year-old woman was admitted for primary amenorrhea and cyclic pelvic pain. Magnetic resonance imaging (MRI) revealed bilateral Müllerian remnants with functioning endometrium and a pelvic mass considered to be an endometriotic cyst. Bilateral Müllerian remnants were removed, and right(More)
While mature cystic teratoma of the ovary is the most common ovarian tumor in young women, immature teratoma is a very rare tumor, representing only 1% of all ovarian cancers. In the three cases presented here, young women who were suspected to have mature cystic teratoma, based on CT scan and MRI, were ultimately diagnosed with immature teratoma Ic (b) G1(More)
