OBJECTIVE To analyze whether blastomere biopsy affects early embryonal growth as observed through time-lapse cinematography. DESIGN Comparative prospective study between embryos in which a blastomere was removed and embryos in which a blastomere was not removed. SETTING An experimental laboratory of the university. MAIN OUTCOME MEASURE(S) We(More)
OBJECTIVE To investigate the clonality of ectopic gland cells in peritoneal endometriosis. DESIGN Prospective study. University hospital. PATIENT(S) Seventeen women with surgically diagnosed endometriosis. INTERVENTION(S) Samples of peritoneal endometriotic lesions were obtained from patients during laparoscopic surgery. MAIN OUTCOME MEASURE(S)(More)
To determine the relationship between premature ovarian failure (POF) and skewed X-chromosome inactivation (XCI), karyotype, and XCI status in 43 patients with POF (group I) and 43 age-matched control women with regular menstrual cycles (group II) were evaluated. Evaluation of XCI status was based on the CAG triplet repeat polymorphism assay in the androgen(More)
Using time-lapse imaging, we found different behavior of mouse embryonal development after blastomere biopsy for preimplantation genetic diagnosis. Blastomere removal has effects on the developmental behavior of the mouse embryo, including speed of growth, contraction and expansion movements, and hatching.
BACKGROUND Cultures of human endometrial tissue are useful for analysing the mechanisms underlying the menstrual cycle. However, long-term culture of endometrial tissue is difficult in vitro. Xenotransplantation of normal human endometrial tissue into immunodeficient mice could allow prolonged survival of the transplanted tissues. METHODS(More)
A 30-year-old-woman presented with uterine leiomyoma and primary sterility. Abdominal myomectomy was performed; however, one cervical leiomyoma was not resected because of a risk of excessive blood loss. Two years after the procedure, a secondary myomectomy using preoperative adjuvant uterine artery embolization (UAE) was performed because of pronounced(More)
Tumors formed by a highly metastatic human lung cancer cell line are characterized by activated signaling via vascular endothelial growth factor (VEGF)-C through its receptor (VEGFR-3) and aggressive lymph node metastasis. In this study, we examined how these highly metastatic cancers acquired aggressive lymph node metastasis. Compared with their lower(More)
AIM Since ovarian endometrioma is frequently diagnosed in women of reproductive age, laparoscopic excision of the endometrioma is performed for most cases. However, endometriomas frequently recurs even after repeated surgical procedures. The aim of our study is to identify risk factors for recurrence and re-recurrence of endometriomas after the first and(More)
A 38-year-old woman, gravida 3, para 1 with a history of a left salpingectomy for an ectopic pregnancy was admitted for treatment of a presumed ectopic pregnancy. Transvaginal sonography revealed an ill-defined gestational sac and fetal heart beat within the fundal myometrium adjacent to the left cornua. Laparoscopy was performed for a suspected left(More)
A 19-year-old-woman had a cystic adenomyoma located within the myometrium. She complained of severe dysmenorrhea. Gonadotropin-releasing hormone agonist therapy was administered, but her dysmenorrhea was more pronounced than before treatment. Therefore, total laparoscopic resection of the lesion was performed. The external appearance of the patient's uterus(More)
