OBJECTIVE: To investigate the gene targets of estradiol (E2)-estrogen receptor-α (ESR1) in human endometrial stromal cells. DESIGN: Basic science. SETTING: University research center. PATIENT(S): Premenopausal women with or without endometr…

Pelvic endometriosis is a complex syndrome characterized by an estrogen-dependent chronic inflammatory process that affects primarily pelvic tissues, including the ovaries. It is caused when shed endometrial tissue travels retrograde into t…

Defective endometrial stromal fibroblasts (EMSFs) contribute to uterine factor infertility, endometriosis, and endometrial cancer. Induced pluripotent stem cells (iPSCs) derived from skin or bone marrow biopsies provide a patient-specific s…

Regenerative medicine offers the potential for replacement or repair of different types of cells within damaged tissues or the tissues themselves, typically through cell therapy or tissue engineering. Stem cells are critical to these approa…

Uterine endometrium is one of the most important organs for species preservation. However, the physiology of human endometrium remains poorly understood, because the human endometrium undergoes rapid and large changes during each menstrual …

Nerve growth factor (NGF) has been recently proposed as one of the key factors responsible not only for promotion of nerve fiber growth but also for the onset and maintenance of pain in a variety of diseases. The aim of this study was to in…

The human uterus is composed of the endometrial lining and the myometrium. The endometrium, in particular the functionalis layer, regenerates and regresses with each menstrual cycle under hormonal control. A mouse xenograft model has been d…

Study objectiveTo investigate clinical features and biologic behavior of ovarian cancer that might be closely related to endometrioma and/or endometriosis.DesignRetrospective study (Canadian Task Force classification II-2).SettingUniversity…

A 55-year-old woman was referred to our hospital for evaluation of a lower abdominal mass. Menopause had occurred at age 52 years. Ultrasonography and magnetic resonance imaging showed a partially solid right ovarian tumor, an appearance su…

This is a report of a live birth after conservative surgery for severe adenomyosis following diagnosis by MRI and therapy with GnRH-a. A 33-year-old gravida 1 para 1 woman with a 5-year history of secondary infertility received a gonadotrop…

We report the first known case of right endometrial cyst and multiple uterine leiomyomata complicated by an ovarian granulosa cell tumour of adult type. A 42 year old woman had an adult type left granulosa cell tumour. Laparoscopy 13 years …

We examined peripheral blood T-lymphocyte subsets before initiation of therapy in 79 healthy controls, 3 patients with endometriosis, 95 patients with common epithelial tumors of the ovary, 15 patients with ovarian germ cell tumors, and 3 p…

The magnetic resonance (MR) appearances of three cases of atypical polypoid adenomyoma are reported. The signal intensity of the tumor was similar to that of adenomyosis on T2-weighted MR Imaging (MRI). On contrast-enhanced study, irregular…

PURPOSE: To assess the value of phase-shift gradient-echo magnetic resonance (MR) imaging with the fast low-angle shot (FLASH) technique in the differentiation of hemorrhagic tumors and teratomas. MATERIALS AND METHODS: T1- and T2-weighted…

Ovarian twin pregnancy is quite uncommon. We present a case of an ovarian twin pregnancy associated with pelvic endometriosis. The ultrasonographic findings in our case were similar to those of malignant ovarian tumor. Five cases of ovarian…

Myosin light chain kinase activity and the amount of calmodulin were measured in rabbit myometrium after the rabbits had been treated with oestrogen, progesterone and human chorionic gonadotrophin, and also during pregnancy. Injections of o…
